Space Time-keeping System is defined a kind of time unification system that is built on the coordinate of barycentre of solar system, to measure proper time based on definition of International Units System (SI) second and cesium atomic clock, and to unify the coordinate time based on pulsars. The current time keeping system on earth thinks the standard time to be unique and absolute, the technology of time dissemination or time service can unify whole human being's time, this thinking is called absolution viewpoint of time keeping. The instruments for measuring time synchronized by standard time, they have none ability and duty to do reproduction of SI second, because their time unit were trained by the dissemination single, and only the atomic clock groups which mission were time keeping have ability of reproduction of SI second. Now, there are about 500 atomic clocks to keep the International Atomic Time (TAI) by means of weight average, local on the earth geoid, and TAI is a kind of proper time on geoid. The earth geoid is actually an ideal ellipsoid surface, and each one atomic clock could not be placed exactly on geoid. In the future, human being will set bases on planet or satellite for long term, and space craft will do exploration task for long term, if still maintains the viewpoint of absolution time keeping, hold the earth standard time and deliver far away to the bases and space craft by the technology of time service, it will be seriously restricted by long distance in time-space. Einstein's theory of relativity told us that the effect of relative speed makes 'moving clock become slower', and the effect of red-shift makes 'clock in weak gravity field become faster', and the effect of Sagnac makes 'temporal metric in non-inertial coordinate depend on rotation rate', therefore, the time is also relative. The theory of space metrology based on General relativity put forward 4 viewpoints that 1) the absolute definition of SI second is a common convention by whole human being, it must be applied to any local and wide area; 2) Simultaneity is only valid in the same coordinate, different coordinates cannot get synchroneity, dissemination time between difference coordinate cannot get high accuracy; 3) the unification of time unit and unification of time measurement are conflict, therefore, the navigation by earth satellite and the navigation by pulsar are two different ways of unifying time; 4) the cesium atomic clock and the pulsar will be micro- and macro- primary standard. Our workgroup continues researched the definition and concept of Space Time-keeping System (STKS) base on the theory of space metrology, and put forward the viewpoint of relative time keeping. First choose the barycentre of solar system as origin of coordinate, this point and infinite far away point, where pulsar is situated, both have the characteristic that their proper time equal coordinate time. Only from origin to observe pulse signal of pulsar, the period is even, time dose not influence by effect of relativistic. Besides origin, from the others point with relative speed and gravity potential to observe pulsar, the result of period is non-even. However, once we take the relative speed and gravity potential as known parameters, and measure proper time by cesium atomic clock which unit follows the SI second, and then transform the proper time into coordinate time by a general relativistic formula, and we can unify time by means of coordinate time in space. In that way, pulsar's period expressed by coordinate time is unified. Within whole frame of solar system, different time from different local area can only compare by the means of their coordinate time. Pulsar can be looked as common tele-primary standard. The signal of pulse is actually plane electromagnetic wave, by giving it sequence number and the time arrived to origin, a feedback system can be built as a stable time keeping system in space. In the viewpoint of relative time keeping, human being needs two conventions, that one is absolution definition of SI second, another one is initial epoch of sequence number of pulsar's signal. The first one had been unified by CGPM, and the second one need scientist's effort. So we put a proposal that establish a workgroup to discuss how to get time rule in space, especially, how to define initial epoch of pulsar's signal. A local workgroup of URSI Commission A in china has built in June 2019. We hope our Commission A to join more scientists for this topic.


This paper proposes a novel approach for human activity recognition based on body part histograms and Hidden Markov Models. From a depth video frame, body parts are segmented first using a trained random forest. Then, a histogram for each body part is combined to represent histogram features for a depth image. The depth video activity features are then applied on hidden Markov models for training and recognition. The proposed method was superior when compared with other conventional approaches.


At the second decade of the 21st century, the use of a new set of agricultural technologies, such as smart farming (SF), emerge among agribusiness organizations and agents. This study aims to identify the smart farming technologies used in grain production systems in Brazil and to verify the perception of the farmers regarding technical assistance for SF. A survey was conducted with farmers and 119 valid observations were collected. The study used non-probabilistic sampling, since it considered grain farmers whose farms produced more than 50% of their gross revenue in grains. Descriptive and content analysis were used to analyze the data. The results indicate that soil sampling is the main precision agriculture technology adopted by the production systems assessed, while smartphone applications to assist in agricultural management are the most used information technology. The machines used in grain production systems are undergoing a digitization process, especially due to the increase in availability of equipment with sensors and automated processes. However, the question remains about the capacity of farmers and assistance agents to monitor and take advantage of the potential of SF technologies in farms.


The kinetics of chromic acid oxidation of glyoxal is reported. The reaction is first-order in glyoxal and indicates a gradual change from a first-order to a zero-order dependence on acidity. The kinetic nature of this reaction has been studied and the rate law is consistent with a proposed mechanism as follows; rate = kKb, K[Cr+6][Gx][H+]/(l+0.238[H+]) at 25°C. The product analysis indicates that formic acid is the oxidation product under similar kinetic condition.

"Have you met our senior manager?" The question was put to the veteran consultant, as an entourage of important looking people swept through the department. "He's been here for years."⇑

A polite handshake and the customary pleasantries ensued, and both parties asserted how lovely it was to meet each other. I melted obsequiously into the background a couple of metres away, knowing my place as a junior doctor. A minute later and the encounter was over.

"I've never heard of him," said the consultant turning to me, with a slightly puzzled look. "I've been …


The history and methods of dip-shooting are outlined and the degree of accuracy obtainable by the method is investigated. Plotting of the misclosures on 151 dip-shooting traverses in the Gulf Coast to yield a frequency curve shows a probable error of about 87 feet, in traverses averaging 27,500 feet in length. This error is apparently independent of the length of the traverse, and within the range of spreads commonly used, that is, from 1,400 to 2,400 feet, independent of the spacing of the dip determinations. The smoothness of the frequency curve is broken by an excessive number of misclosures greater than 250 feet. These may be due to unusual structural conditions on the traverses concerned, such as terracing between dip points or faulting, or to gross personal errors. he principal common errors appear to lie in the drafting of the profiles, the determination of the time step-out, and the weathering correction. These errors on individual dips may considerably exceed the probable error, but on traverses of average length will tend to compensate one another. Other sources of error are discussed, but are believed to be of minor importance.


without morbidity and detractors. There is a need for a more formal survey and more uniform protocol, validated by empirical data. Of course the argument that efficacious electroencephalograph (EEG) seiz ure activity can occur in the absence of a clinically detectable fit impacts upon this subject and warrants further study. Nevertheless, in the interim, specific attention should be given to whether the application of a repeat stimulus significantly increases the likeli hood of a fit and, if the stimulus is repeated, what its optimal characteristics (e.g. amplitude and duration of current) and †̃¿ climate' (e.g.degreeof oxygenation of patient, concurrentdrug therapy) should be.

Nickel phthalocyanine (NiPc, 1) periphery has been decorated by alkyl chains of varying chain length via [1,3,4]-oxadiazole moiety (NiPcs 3a–3f). All the newly synthesized compounds NiPcs 3a–3d have been completely characterized by elemental analysis, FT-IR, solid-state UV-Vis, and solid-state 13C NMR spectroscopy, in addition to X-ray diffraction, scanning electron microscopy, and thermal analysis. The effect of chain length in the NiPc periphery on electronic absorption and DC electrical conductivity has been investigated.


LED (light emitting diode) is a solid luminescent source of fairly wide uses, a type of electronic components capable of transforming electric energy to luminous energy, which, emitted from LED, is highly centralized and strongly directive. LED can be driven simply by low-voltage direct current. This paper chiefly introduces the actualization of drive circuits by the constant current pattern, and proposes a type of high-power LED constant current drive solutions based on the constant current drive circuit PT4115. This drive circuit is simple, highly efficient and cost effective, suitable for the market demand of solar energy products.


This article examines referral exchange relationships between black churches and local community health agencies by examining whether organizational and clergy characteristics influence clergy in black churches to refer parishioners to, and receive referrals from, community mental health agencies. We are interested in identifying the typical characteristics of churches and their clergy that tend to participate in these exchanges. The most significant indicators in predicting the probability of church referrals are the extent of interorganizational links and the size of a church. The data do not, however, suggest a reflective relationship; organizational factors do not significantly predict whether a church receives client referrals from community Agencies. We speculate that the lack of reciprocity in this pattern may be caused by a conflict in the levels of rationality within community agencies.


Paddy is a labour-intensive crop and requires about 90 labour days during one season. Timely availability of labour for various activities is becoming a problem for farmers in Andhra Pradesh. This can be attributed to several factors including the migration of labourers from villages to nearby towns and cities in search of employment. With agriculture becoming risky due to frequent weather changes (droughts and floods), people in rural areas find it more secure to get a job in urban areas. Another factor are the ongoing government welfare programs such as the National Rural Employment Guarantee Act (NREGA) that hire rural people. The government of India has also passed a number of laws in order to promote the standard of labour in agriculture. These laws concern issues such as minimum wage fixing, equal remuneration, discrimination (employment and occupation), minimum age convention, safety and health in agriculture convention.


neous rupture: successful closure with endoscopic suture device We report a case of successful closure of postoperative esophageal leakage using an endoscopic suture device. A 60-yearold man was initially admitted for spontaneous rupture of the esophagus requiring emergency surgery. Intraoperatively a 3-cm perforation was identified on the right side of the lower esophagus. Themucosal defect was first closedwith a laparoscopic linear stapler (EndoGIAUltra; Covidien, Medtronic, Minneapolis, Minnesota, USA) while the muscular defect was approximated with absorbable interrupted sutures (●" Fig.1). He developed fever and leukocytosis again on postoperative day 10, and computed tomography (CT) of the thorax showed the presence of a right pleural collection and posterior mediastinal gas locules suggestive of leakage. Image guided drainage of the pleural collection was performed. Esophagoscopy subsequently located the leakage site at the mid-esophagus over the distal end of the previous surgical repair (●" Fig.2). Two figure-of-eight sutures were applied using an endoscopic suture device (Overstitch; Apollo Endosurgery, Austin, Texas, USA) and good approximation of tissue was achieved (●" Fig.3, ●" Video 1). Later, nasojejunal feeding was initiated. Repeat endoscopy 2 weeks later showed that stitches from the previous endoscopic intervention had remained in situ and good healing of the leakage site was observed (●" Fig.4a,●" Video1). Contrast injection showed no further leakage at the esophagus (●" Fig.4b,●" Video1). An oral diet was resumed and the patient was discharged home.

However passive sleep may seem, in reality a complex neurological factory is working hard. During wakefulness, most new information gets stored temporarily in the short-term memory part of your brain. Only during sleep, this new information gets integrated into already existing neural networks, ready to be stored for the long term. During sleep, memories are being 'replayed', strengthening their accessibility. During this process, new and existing networks get re-organized, facilitating a higher level of abstraction and insight, while clearing brain capacity for new learning tasks (Feld & Diekelmann, 2015).


The article addresses the problems of defining an indigenous people by deconstructing the Sámi debate in Finland, which has escalated with the government's commitment to ratify ILO Convention No. 169. We argue that the ethnopolitical conflict engendered by this commitment is a consequence of groupism, by which, following Rogers Brubaker, we mean the tendency to take discrete groups as chief protagonists of social conflicts, the tendency to treat ethnic groups, nations and races as substantial entities and the tendency to reify such groups as if they were unitary collective actors. The aim of the article is to deconstruct groupist thinking related to indigenous rights by analytically separating the concepts of group and category. This allows us to deconstruct the ethnicised conflict and analyse what kinds of political, social and cultural aspects are involved in it. We conclude that indigeneity is not an ethnocultural, objectively existing fact, but rather a frame of political requirements.


cell membrane phospholipids. Choline is metabolized through phosphorylation that produces phosphorylcholine through choline kinase, further incorporated into phosphatidylcholine, a major component of biological membranes and a member of the lecithin group of yellow-brownish fatty substances. Choline is also metabolized through acetylation through choline acetyltransferase, which produce acetylcholine. Thus PET/CT imaging with C-choline and F-fluorocholine can be used to identify tumoral tissue where an increase in cell proliferation as well as the activity of the enzyme choline is associated with an increase in choline component and has long been used in work up of prostate cancer. Apart from prostatic adenocarcinoma, F-choline PET/CT is known to have good performances in other neoplastic cell type, such as hepatocellular-carcinoma, glioma, bone tumor, soft-tissue tumor, and lung cancer. Besides, F-choline PET/CT can be useful in detecting hyperplastic tissue, such as thymomas and parathyroid adenoma. But for lung cancer, even for bronchioloalveolar cancer subtype, although F-choline PET/CT is a reliable tool for lung tumor staging and to differentiate malignant and benign lung lesions (through the phosphorylation and acetylation pathways), a superiority of F-choline over FDG has not been demonstrated in this setting, except for the detection of brain metastases, whereas its price is three to five times the price of FDG. F-choline PET/CT imaging, like F-FDG PET/CT scan, is also subject to several causes of false-positive, such as infection, tuberculoma, or inflammation. There is only one published case of mucinous cancer detected with F-choline PET/CT. It was a primary poorly differentiated mucinous rectal cancer. So in the case of the mucinous colorectal adenocarcinoma lung metastasis reported by Balata et al.; whether F-choline PET/CT could have significantly contributed to diagnosis remains uncertain. The differentiation degree could play a role in the avidity of tumor cell for F-choline. The spatial resolution of F-choline PET/CT (from 4 to 8 mm) being similar to that of F-FDG PET/ CT, the positivity of F-choline PET/CT Address for correspondence: Jérémie Calais, MD, Médecine Nucléaire et Biophysique Hôpital Bichat, 46 rue Henri Huchard 75018 Paris, France.

Most large elliptical galaxies should now host a massive black hole leftover from an earlier quasar phase. Such galaxies also have an extensive hot gaseous halo. Here we consider why the nuclei of elliptical galaxies are not luminous sources due to the accretion of the hot gas by the central black hole, yet have weak radio sources. In particular we suggest that accretion from the hot medium has low radiative efficiency and forms a hot ion torus surrounding the black hole. Synchrotron emission from the torus can account for at least part of the weak radio sources commonly seen in otherwise normal elliptical galaxies. The inner funnel of the ion torus can also begin the collimation of a narrow jet. We speculate on the difference between jets from the nuclei of spiral and elliptical galaxies and suggest that the extensive hot atmosphere seen in ellipticals is essential for maintaining the collimation and provoking the observed radio structures of radio galaxies. We also note that low radiative efficiency, and not necessarity a large change in accretion rate, may be responsible for the demise of quasars and may contribute to the hard X-ray Background. Hot ion tori may be common in galactic nuclei.


Objective To investigate the effect of respiratory function training on respiratory function and conscious state of patients with severe cerebrovascular disease (SCVD). Methods A total of 27 patients with SCVD were divided into control group (N = 17) and observation group (N = 10). Control group received routine drug and rehabilitation treatment, and observation group was added respiratory function training based on routine treatment. The respiratory rate, tidal volume (TV), heart rate, blood pressure and artery oxygen saturation (SaO 2 ) of patients were monitored by breathing machine before and after 4-week treatment. Meanwhile, arterial blood gas analysis was used to detect arterial partial pressure of oxygen (PaO 2 ), oxygenation index, partial pressure of carbon dioxide (PaCO 2 ) and pH value. At the same time, Glasgow Coma Scale (GCS) was used to evaluate the conscious state of patients.  Results All patients successfully completed 4-week rehabilitation training, without asphyxia, arrhythmia or other adverse events. Compared with before training, the respiratory rate ( P = 0.006) and pH value ( P = 0.010) were significantly decreased, while SaO 2 ( P = 0.001), oxygenation index ( P = 0.000) and GCS scores ( P = 0.004, 0.017) were significantly increased in both groups of patients after training. There was no statistically significant difference between 2 groups on respiratory function indexes and GCS scores after training ( P > 0.05, for all). Conclusions Respiratory function training did not significantly improve the respiratory function and conscious state of patients with SCVD, yet to be further studied. Randomized controlled clinical trials with larger, layered samples and long-term prognosis observation are needed. Examination method of respiratory function of SCVD patients is also a topic to be explored. DOI: 10.3969/j.issn.1672-6731.2017.04.007


Much of the criticism of Stevens's criterion for permissible statistics as applied to measurement data results from a lack of clarity in Stevens's position. In this paper set-theoretical notions have been used to clarify that position. We define a sig-function as a function defined on numerical assignments. If A and R are empirical and numerical relational systems, respectively, then a sig-function F is constant on A with respect to R if, and only if, the value of F is the same for all numerical assignments for A with respect to R. Using these notions we prove rigorously certain generalizations of Stevens's results.


Hyperspectral unmixing is the process of finding the fractional abundances and corresponding spectral signatures of a mixed pixel in a hyperspectral image. However, several types of noise such as dead pixels, stripes, impulse noise and Gaussian noise called as mixed noise are introduced in the hyperspectral images due to imperfect imaging sensors and atmospheric conditions, which degrades the performance of the unmixing algorithms. We propose a robust semi-supervised unmixing method to obtain the fractional abundances of the spectral signatures based on low-rank representation (LRR)and total variation (TV)using a a priori available spectral library. LRR estimates the global lowest rank representation of the abundance matrix whose columns are the abundance vectors of each pixel and TV regularization promotes the spatial piecewise smoothness of the abundance map. The sparse noise components are suppressed using an $l_{1}$ norm regularization term. Extensive simulation results on synthetic and real hyperspectral data sets show that the proposed method is effective in obtaining the abundance maps under mixed noise.


Our earlier arguments (Berry M V and Robbins J M 1997 Proc. R. Soc. Lond. A 453 1771-90) leading to the spin-statistics relation are summarized and then revisited. Constructions are described that satisfy all our previous requirements but lead to the wrong exchange sign (one such alternative is the replacement of commutators by anticommutators in the Schwinger representation of the spins of the particles); we suggest why these might be unacceptable.


One potential application of multirobot systems is collective transport, a task in which multiple robots collaboratively move a payload that is too large or heavy for a single robot. In this review, we highlight a variety of control strategies for collective transport that have been developed over the past three decades. We characterize the problem scenarios that have been addressed in terms of the control objective, the robot platform and its interaction with the payload, and the robots' capabilities and information about the payload and environment. We categorize the control strategies according to whether their sensing, computation, and communication functions are performed by a centralized supervisor or specialized robot or autonomously by the robots. We provide an overview of progress toward control strategies that can be implemented on robots with expanded autonomous functionality in uncertain environments using limited information, and we suggest directions for future work on developing such controllers. Expected final online publication date for the Annual Review of Control, Robotics, and Autonomous Systems, Volume 5 is May 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.


The temporal and spatial behavior of a large-amplitude filament oscillation is investigated using wavelet analysis. The extreme-ultraviolet (EUV) images of the phenomenon, which occurred on 2002 October 15, were taken from the EUV Imaging Telescope on board the Solar and Heliospheric Observatory (SOHO). The wavelet spectra, extracted from the intensity data, show that the filament oscillates as a rigid body, with a period of about 2.5Y2.6 hr which is almost constant along the filament. The period slowly decreases with time until the filament erupts. No clear sign of the eruption is found in the wavelet spectrum prior to the eruption, that followed the filament oscillation. The axial component of the magnetic field is estimated between 1 and 5 G, which is believed to be reasonable for a polar crown filament of this kind.

This bachelor thesis on the topic of patients self-care after the breast cancer surgery is aimed at mapping the problem of breast cancer diagnosis and treatment. It deals with problems that may occur on these patients. The basis of the submitted work is the theory of self-care deficit by D. E. Oremova. According to this theory the need of patients self-care situation after surgery of breast cancer was made. The aim is to monitor the activities of self-care patients after surgery of breast cancer treatment interventions, the impact of the disease at the personal life and to find the most common problems that worry patients. To meet these objectives, the questionnaire survey was used. One of the findings was also that women after undergoing the breast cancer surgery don?t know the breast forms or they use them very little. For that reason the educational material for patients focused on the follow-up care after surgery for breast cancer using breast forms - breast replacements entitled "Availability and use of breast forms after breast surgery? was made.


Despite the availability of several atmospheric reanalyses (e.g. ERA‐Interim) there exists both considerable uncertainty in surface forcing fields for ice/ocean modelling and sensitivity to the choice of product used. Here we introduce a relatively high‐resolution alternative forcing dataset for ice–ocean models derived from the Canadian Meteorological Centre's (CMC) global deterministic prediction system (GDPS). A set of daily 30 h reforecasts is produced using the GDPS 33 km resolution model providing hourly atmospheric forcing fields for the period 2002–2011. The CMC GDPS reforecasts (CGRF) are compared with ERA‐Interim and several observational datasets to evaluate their suitability for forcing ocean models. In particular, the surface temperature, humidity and winds of the CGRF show equivalent biases to those found in ERA‐interim. Moreover, the higher resolution of the CGRF permit a more detailed representation of atmospheric structures and topographic steering, resulting in finer‐scale coastal features and wind‐stress curl. Although the CGRF dataset is not a reanalysis and thus is expected to be less well constrained by available observations, its higher resolution and small bias make it an attractive alternative for forcing ice‐ocean models.

Abstract:Iberomedievalism in the United States has always been at the cutting edge of innovative approaches and methodologies. The development of computational, and subsequently digital, techniques corresponds almost exactly with the existence of La corónica. This article, in part a response to Kathleen Kish's update on the activities of the Wisconsin Seminary of Medieval Spanish Studies published in 1979, traces the significance of the journal as an important part of the dissemination of new techniques and methodologies in the study of medieval Iberia.


The transition to the new content of education in the elementary school has been prepared by fundamental psychological and pedagogical research that demonstrates the possibility of essentially changing the nature of the entire elementary education process. The findings of scholarly teams headed by L. V. Zankov, A. A. Liublinskaia, M. A. Mel'nikov, N. A. Menchin-skaia, D. B. El'konin, S. M. Iazykov, and other scholars are of fundamental importance. Colleagues of the USSR Academy of Pedagogical Sciences, in collaboration with personnel of other scholarly pedagogical institutions, have worked out both the theoretical principles and the curricular content for the reorganization of elementary instruction throughout the country. As a result of their research, the feasibility of a three-year period of elementary education was demonstrated and new syllabuses for grades 1-3 were compiled after many years of experimental verification.

The object of research is the mode of movement of the granules of mineral fertilizers obtained in the towers. The subject of research is the effect of the physical and chemical properties of granules, their size and initial hydrodynamic parameters on the speed of movement of the granules in the tower. The fertilizer industry is characterized by high requirements for the production of mineral fertilizers, which makes it promising to use granulation plants of large unit capacity, tower production. The resulting product must have a stable physical and chemical composition, be monodisperse with a spherical shape of granules, which allows long-term storage in bulk without the use of auxiliary equipment and meet international quality standards. The main granulation equipment that is used in the tower production of mineral fertilizers is spray type granulation equipment. In such towers, there is a likelihood of crossing pellet flares, getting pellets into the walls of the pelletizing tower and adhesion of the melt on this surface in industrial conditions, which leads to negative consequences. Therefore, the determination of the modes of motion of granules is still important. Methods of mathematical modeling of the movement of granules under different conditions were used in the work. Numerical methods were used to solve the equations of differential equations. As a result, an equation was obtained to determine the speed components along the x and y axes. The calculation of the horizontal speed of the granule and the determination of the time of its movement in the working area of the prilling tower makes it possible to determine the length of the granule path in this direction, to determine the diameter of the spray torch of the granules. Provides information on preventing the ingress of granules into the walls of the prilling tower and adhesion of the melt on this surface in industrial conditions, which leads to negative consequences. The magnitude of the speed, especially for the vertical component, changes its value several times over time due to a change in the mode of motion of the granules when moving from the granulator down the tower. This indicates the need to also take into account the change in the value of the resistance coefficient over time. When deriving the equations, simplifications were used, and the motion of a solid granule was considered. However, a drop begins to move from the granulator (disperser), which then crystallizes into a granule. Comparing the obtained results, allowing to predict by calculation the behavior of the spray plume of granules, with the initial ones obtained in industrial conditions, it is possible to conclude that the error of the equations obtained is 10.5%. Therefore, work on improving the obtained equations describing the mode of motion (speed) of the granules will be continued.


This study deals with analysis of grid integrated Switched Reluctance Generator (SRG) based wind farm control using Modified Hybrid Multicell Converter (MHMC). A Finite Element Analysis (FEA) model is developed for the existing machine geometry using MagNet 7.1.1 and solved to obtain the parameters like flux linkage, inductance and torque. The data obtained from FEA Model is utilized to develop model of SRG in the MATLAB/SIMULINK environment. Asymmetric Half Bridge Converter (AHBC) with dedicative buses for source and load is used for excitation. Developed wind turbine with Maximum Power Point Tracking (MPPT) algorithm to extract maximum power from the wind turbine. Output of the SRG is integrated with grid through Modified Hybrid Multicell Converter. The MHMC uses a flying capacitor module on each cell to generate a positive variable dc-link voltage. The variable dc link is inverted at fundamental switching frequency by an H-bridge to generate the cell output voltage. Phase-Disposition level-shifted Pulse Width Modulation (PD-PWM) Technique is used to obtain the high performance waveforms. In this study wind farm having four SRG'S controlled through MHMC is proposed.

Purpose – This study aims to provide insights into glocalisation of international channels of distribution. The study also seeks to identify the key principles and patterns of glocalisation in general.Design/methodology/approach – The authors utilise the single case study approach to study glocalisation in international channels of distribution by conducting in‐depth interviews with the firm's senior executives.Findings – Results reveal that the firm employs glocal channels of distribution strategies. The study specifically identifies two types of glocalisation: inter‐decision and intra‐decision, and it is found that the firm follows a combination of both. The findings also suggest that the decision on how to glocalise channel strategies is based upon the firm's global practices as well as several local conditions specific to individual markets.Practical implications – The study concludes that there is no uniform formula to pursue glocalisation. Firms may choose to pursue inter‐decision or intra‐decision ...

To manage fishery resources in Indonesia with the principle of sustainability, it is necessary to apply the ecofishing port concept. This study aims to develop a model for assessment of eco-fishing port with prevailing conditions and regulations in Indonesia. From the model that prepare, the application on Coastal Fishing Port (PPP) Pondokdadap has result value of the eco-fishing port is 67, with details of ecological indicator value 58, fishing indicator value 69 and port indicator value 76. The value indicates that PPP Pondokdadap has not met the criteria of eco-fishing port conformity (value 80-100) and in the process of applying the fishing port management principle of environmentally friendly. The non-fulfillment of these criteria is due to the environmental regulations not implemented properly, or the level of compliance under 100%. From the indicators obtained a fishing port environmental management index (FEMI) this study developing a model of eco-fishing port management, which use as a tool to check the fishing port environmental management development. Increased FEMI values will show that improvements in ecological, fishing, and port indicators to fulfill eco-fishing port assessment standards.

Coronavirus disease (COVID-19) is spreading rapidly at an unprecedented
scale across continents and has emerged as the single biggest risk the world has faced in modern times.
Some scientists are comparing it to Spanish flu that created havoc around a century ago. The fear of
death by COVID-19 looms large in the world today. The disease has reached devastating proportions
since its first reports in December 2019. Doctors are having a difficult time dealing with this challenge
and the microbiologists are having sleepless nights to bring about an effective vaccine for this disease.
Methods: A number of research and review articles have been exhaustively reviewed. The collected data
has been meticulously analyzed and documented.

 This paper reviews the different types of coronaviruses, the structure of SARS-CoV-2 responsible
for COVID-19, its transmission, and virulence. Further, the article discusses the diagnosis,
signs and symptoms like fever, breathlessness, cough, potential loss of taste or smell, sneezing, runny
nose, fatigue, headache, sore throat and different treatment approaches including drug repurposing being
tried by doctors around the globe that may come handy in the management of disease symptoms. The
article describes the use of remdesivir, ribavarin, lopinavir, favipiravir, hydoxychloroquine, chloroquine,
and tocilizumab among others in treating COVID-19.


The dairy industry consists one of the most energy intensive food industries, with milk powder production being the most energy consuming process. The aim of this work is to present the state of the art skimmed milk powder production processing chain in order to identify the processes with high environmental and energy impact. A life cycle assessment (LCA) has been performed to analyse the environmental footprint and energy balance derived from the skimmed milk powder (medium heat) production on the post-harvest chain. Therefore, a comparative gate to gate LCA was performed within the boundaries of the processing plant (i.e. standardization/separation, homogenization, pasteurization, evaporation, spray drying). In this study, two scenarios were evaluated on their environmental performance: a) the conventional production of skimmed milk powder (SMP) with the inclusion of Reverse Osmosis (Scenario 1) and b) the production of SMP exclusion of Reverse Osmosis (Scenario 2). The standard framework of LCA was followed according to the ISO 14044, which is also in line with the International Reference Life Cycle Data System (ILCD) Handbook. LCA study was performed on Gabi 6 software with databases from within the food industry. Inventory data were collected from the industry and completed using the literature and databases, impact categories were evaluated adopting a CML method with the energy analysis carried out based on the cumulative energy demand (CED).

Antonovsky has proposed the sense of coherence (SOC) as a crucial factor that protects against symptoms of mental disease. A central issue in research on the SOC construct is whether this is most appropriately considered as one‐dimensional or three‐dimensional with comprehensibility (C), manageability (Ma) and meaningfulness (Me) as separate dimensions. In this paper we address this issue by means of confirmatory factor analysis of a shortened nine‐item version of Antonovsky's original 29‐ and 13‐items Sense of Coherence Scale (SOCS‐29), using epidemiological data from a mental health survey of adults in local communities (N = 1,062). In addition to analysing the internal structure of the SOC items, we examine the association between estimated factor scores and variables expected to be statistically related to SOC. Goodness‐of‐fit indices were very good for the three‐factor model but acceptable even for the one‐factor model. In the three‐factor model, however, the factors were found to be very highly or, with regard to Ma and C, even perfectly correlated. Moreover, the factor scores had very similar correlations with measures of psychological wellbeing, depression and anxiety and they are also very similarly related to age (and none of them are related to gender). We therefore conclude in favour of a one‐factor model. Copyright © 2006 John Wiley & Sons, Ltd.


A review of those forms of standard quantum mechanics that include the Pauli Exclusion Principle as it is applied to atomic species, (that is versions of quantum that are multi-electron and multi-orbital) shows they are not consistent with energy conservation. Particular focus is given to helium in which it is shown that energy conservation is not consistent with current models. If the two electrons in the ground state, per current theory, are at the same energy as the ionization energy, it is demonstrated that according to the standard theory approximately 30 eV are lost during ionization, or alternatively, about 30 eV of energy are created during ionization/electron attachment. The same issue of energy loss during relaxation of energy levels following ionization is shown to exist for all atomic species, thus demonstrating that the Pauli Exclusion Principle (PEP) and energy conservation are not consistent for any atomic species for current forms of distinguishable electron forms of quantum theory. Only that form of quantum that has a single orbital, and for which only one ionization energy can be computed (that is the original Schrodinger form), is consistent with an energy balance. However, this form is not consistent with common spectroscopy results, and it is argued PEP has no meaning in this form of quantum theory. In contrast a new model, Classical Quantum Mechanics (CQM), invented by R. Mills,, following modification, is consistent with all spectroscopy and energy conservation for bound electron systems. This new model is based on the validity of Maxwell s Equations and Newton s Laws at all scales. Detailed, and remarkably simple, computations for determining the ground state energy levels in one and two electron systems using CQM are presented. Agreements with data are excellent.


Up to now, neither technical guidelines nor experiences for public medium voltage direct current (MVDC) grids exist leading to different questions concerning the design of these grids. Therefore, this paper analyzes relevant technical options for realizing MVDC grids. Technical requirements and degrees of freedom, including grid structure, operating voltage, line configuration, possible apparatuses, grid operation, power flow controllability and protection equipment are elaborated. An optimization method which allows to consider these different options and which can be applied for developing MVDC grids is presented. For an exemplary supply task, two grids are designed. Resulting grid structures indicate that the choice of line configuration and operating voltage has a significant impact on power transmissibility and the necessary amount of power lines. By choosing an asymmetric monopole and a comparatively low operating voltage for the given supply task, a more meshed grid structure results, also to avoid voltage problems. Based on further sensitivity analyses the impact of different technical options on MVDC grid design can be investigated and knowledge concerning MVDC grids can be gained, which is essentially required for further research as well as for the development of standardizations and MVDC grid components.

In the literature, there is an extensive discussion on cities demetropolitanization or metropolization and their role across their area of influence. This study discusses these issues taking as a subject the Metropolitan Region of Belem (rmb), capital of Para State, Brazilian Amazon. It recovers the history of the territorial development of Belem over almost 400 years, and using economic data and official former studies on Brazilian urban network, this paper seeks to demonstrate the coexistence of two dynamics in rmb. One associated to its role as the prime city within the Amazon network until the mid-twentieth century, and another that reveals the incorporation of the region to the industrial capitalist dynamics of Brazil after the 1950s. We may say that despite of the ratio decreased in the State' gdp, rmb's metropolitan expansion and services specialization shows that it has actually assumed new functions and maintains the characteristics of a regional metropolis.


Introduction Livestock and poultry producers continually face economical and time restraint challenges. They seek a lifestyle that does not demand 10 to 16 hours of labor each day. As a result, producers have expanded and concentrated their operations in recent years to make the operation more efficient and bring in additional labor to share the workload. However, this expansion has also resulted in a community concern about emissions of air pollutants, especially odorants. Because of this concern, there has been an increase in complaints towards animal production facilities (Figure 1).

L'analyse conclut que si les gammes operatoires sont tenues a peu pres a jour par les logiciels adequats et s'il existe un suivi de l'evolution du prix des ressources, la methode UVA est un outil commode pour calculer des couts.(VA)This article shows that the principal source of error in the AVU method is the error of aggregation. It then looks further into the conditions which prevent this error from becoming too significant.

The vital signs of respiratory rate, pulse oximetry, heart rate, blood pressure, level of consciousness (Glasgow Coma Scale, GCS) and temperature are recorded because, if abnormal, they indicate that a patient has deranged physiology. This derangement may be indicative of a disease process with the risks of morbidity and mortality. To be of value, these observations need to be made on the correct population and repeated at a frequency that will provide useful information on the progression of the disease. Much time and effort is expended within nurse training and practice to obtain vital signs, yet there is no nationally agreed standard for this common nursing activity within the emergency department. We need to agree on the patients in whom vital signs should be measured, which vital signs, how often and, importantly, what should be done with that information. It should be emphasised that the measurement of vital signs complements all the other senses involved in patient assessment rather than replaces them. What follows are a series of proposed standards which, if agreed and implemented, could establish the value of such observations.

There are four areas which we would …

For the first time, the Weather Research and Forecast (WRF) model with the Wind Farm Parameterization (WFP) modeling method is utilized for a short-range wind power forecast simulation of 48 h of an offshore wind farm with 100 turbines located on the east coast of the China Yellow Sea. The effects of the horizontal multi-grid downsize method were deployed and investigated on this simulation computation. The simulation was validated with the field data from the Supervisory Control and Data Acquisition (SCADA) system, and the results showed that the horizontal mesh downsize method improved the accuracy of wind speed and then wind power forecast. Meanwhile, the wind power plant aerodynamics with turbine wake and sea–land shore effects were investigated, where the wake effects from the wind farm prolonged several miles downstream, evaluated at two wind speeds of 7 m/s and 10 m/s instances captured from the 48 h of simulation. At the same time, it was interesting to find some sea–land atmospheric effects with wind speed oscillation, especially at the higher wind speed condition. Finally, the research results show that the WRF + WFP model for the wind power forecast for production operation may not be ready at this stage; however, they show that the methodology helps to evaluate the wind power plant aerodynamics with wake effects and micrometeorology of the sea–land interconnection region. This plant aerodynamics study set the stage for a wake turbine interaction study in the future, such as one utilizing the NREL FAST.FARM tool.


Introduction: Patellar instability is a frequent cause of total knee arthroplasty (TKA) failure. In cases of post-arthroplasty patellar instability, the medial structures may be damaged. The objective of this study was to study the effectiveness of medial patellofemoral ligament (MPFL) reconstruction. We hypothesized that MPFL reconstruction will effectively realign the patella, making it a viable treatment option for managing post-arthroplasty patellar instability. Material and methods: In this retrospective study of six patients treated by four different surgeons, patients were included if they had a recurring or permanent patellar dislocation after undergoing TKA. Patients were excluded if the patellar instability was painful but did not result in dislocation. Each patient underwent MPFL reconstruction using the gracilis; additional procedures could be performed depending on the diagnosis. One patient required TKA revision because of an abnormally rotated femoral implant. The main outcome measure was the non-recurrence of the dislocation. The IKDC and Kujala functional scores, joint range of motion and patellar tilt on X-rays were analyzed preoperatively and at the last follow-up. Results: At a mean follow-up of 23 months (6–46), none of the patients experienced a recurrence of the patellar dislocation. Only one patient had no improvements in the functional outcome scores. The patellar tilt was reduced in all patients. Conclusion: MPFL reconstruction—in isolation or with femoral component revision—is effective at treating post-arthroplasty patellar instability. It has its place in the treatment of patellar dislocation following TKA and its indications must be based on exact analysis of the reasons for the instability. rospe Level of evidence: IV – Ret . Introduction Patellar instability is often the cause of total knee arthroplasty TKA) failure [1,2]. The reason underlying this instability must be etermined precisely before it can be treated: error in prostheis implantation (abnormal internally rotated femoral and/or tibial omponent, poorly restored patellar offset; medialization of the emoral component or abnormal patellar resurfacing), alignment efect, excessively large tibial tuberosity to trochlear groove (TTG) distance, and/or patella alta [3,4]. After TKA, the medial patellar estraining structures may be damaged because of the use of a edial parapatellar approach or patellar dislocation; this can be he root cause, either alone or in combination with other factors, of ecurring patellar dislocations. ∗ Corresponding author.

Among the various surgical methods for treating frank patellar instability on an otherwise normal knee, medial patellofemoral ligament (MPFL) reconstruction is being used more often [5–9]. To our knowledge, few cases of this technique being used to realign the patella following TKA have been described [10–15]. The objective of this study was to evaluate the effectiveness of MPFL reconstruction in this context. We hypothesized that by effectively realigning the patella, MPFL reconstruction is effective at managing post-arthroplasty patellar instability. 2. Material and methods 2.1. Study population Six patients (3 men, 3 women) with a mean age of 77 years (70–87) were included in this retrospective study of MPFL reconstruction cases carried out between September 2011 and September 2014 by four surgeons (Table 1). diffuser ce document. 608 A.

The purpose of this research is to understand the conditions of attributes of MICE destinations in Medan City and strategic development plan for MICE destinations to increase comparative advantage using the Cooper method approach in Medan City. This research is conducted using quantitative survey method. Questionnaire and interview are carried out as the data collecting method. The population of this research are the government stakeholders, which are represented by Medan City Tourism Office, and MICE industry entrepreneurs. The sampling technique is conducted by choosing the appropriate respondents which fit the sample criteria. Gap analysis is used as the data analysis method. The outcome of this research shows that the perceptions of the government stakeholders regarding the attribute of MICE are higher compared to those of the MICE industry entrepreneurs. Only the attribute of amenities has low gap, with the value of 0.1. The attribute of attraction possesses the highest gap value. Therefore, it is important for the government to increase the attribute of attraction which includes everything that can be shown to the tourists whether it is culture, natural richesse, or man-made attractions of Medan City to increase the level of comparative advantage of Medan City as a tourism destination.


The nickel catalysts derived from Cr-doped LaNiO3 perovskite-like precursors were characterized by X-ray diffraction, high-resolution transmission electron microscopy, temperature-programmed oxidation, temperature-programmed reduction, and X-ray photoelectron spectroscopy. Their catalytic performance in CO2 reforming of methane under microwave irradiation was investigated. It was found that the structure and morphology of the oxide composites in this research were influenced by the ratio of Ni and Cr, and the mismatch of La3+, Ni3+, and Cr3+ may cause phase segregation. The catalytic performance of the Ni catalysts is dependent on the oxygen mobility of the perovskite oxide matrix, the content of the reduced Ni0, and the content of the remaining perovskite structure. The mobile oxygen in the perovskite matrix in the catalyst may enhance the conversion of CO2 during the reaction.


The effects of varying periods of pre-sampling handling (1.5 min, 3 min, 4.5 min, 6 min) on selected biochemical indices were monitored in a group of 8–9-month-old common pheasants (Phasianus colchicus) kept at a pheasantry in Jinacovice, Czech Republic. The duration of pheasant handling (capture, restraint, and blood sampling) was positively correlated with plasma corticosterone (p < 0.001) and lactate (p < 0.05) levels. Negative correlations were found between the handling duration and glucose concentration (p < 0.01), and aspartate aminotransferase level (p < 0.05) in the blood plasma. A significant increase in corticosterone plasma concentrations and a decrease in glucose plasma concentrations were already found in blood samples taken after 3 min of capture in comparison to blood samples of pheasants taken within 1.5 min. Corticosterone, glucose, blood sample, sampling time, capture, stress Current scientific research has focused on stress in animals with the aim to identify factors affecting animal well-being, both in captivity and in its natural habitat. Since one of the hallmarks of stress in birds is the release of corticosterone, a member of the glucocorticoid family of steroid hormones, there has been an interest in analyzing corticosterone concentrations in both domestic and wild birds (Romero and Romero 2002). Collecting blood for glucocorticoid analysis that involves capture and handling of birds is at present the most common way of determining corticosterone concentrations, even though there were attempts to avoid possible stressful effects of blood sampling per se by measuring faecal concentrations of glucocorticoid metabolites (Kotrschal et al. 1998; Harper and Austad 2000; Goymann et al. 2002). Evaluating an animal's response to stress-inducing events requires knowledge of the baseline concentrations of the monitored indicators - presumed to reflect pre-stress levels (Romero et al. 1997; Wingfield and Romero 2001). It is well documented that in particular the duration of pre-sampling handling influences hormonal levels, and corticosterone concentrations quickly rise (Romero 2004; Romero and Reed 2005; Voslařova et al. 2008). Romero and Romero (2002) emphasized that the elapsed handling time before sampling is a critical variable in the stress responses in wild birds. However, only a few studies have directly tested whether glucocorticoid concentrations begin to increase in the first few minutes of capture, and results have been equivocal (Romero and Reed 2005). Wingfield et al. (1982), Schoech et al. (1999), Sockman and Schwabl (2001) and Voslařova et al. (2008) indicated that corticosterone did not change in the first 3 min in their avian studies. In addition, Mizrahi et al. (2001) found changes in corticosterone titres between the 3 and 5 min mark. In contrast, Dawson and Howe (1983) reported a corticosterone increase after only 1 min and Romero and Reed (2005) approximately 2 min after capture. Since corticosterone concentrations vary within animal species,


My PhD work thesis is divided in two sections, the first one is an academic part and the second one is an industrial part.
The first part of my thesis represents a contribution to the program of the research group of the Department of Organic Chemistry of the University of Camerino, that has for a long time been studying the cerium chemistry and has dedicated itself particularly to the study of new
methodologies involving the use of system CeCl3·7H2O with NaI.
In many trials good results have been achieved and the procedures developed are characterized not only by the efficiency of the reactions, but also by chemoselective
processes, by a good stereochemical control, by reacting available and inexpensive reagents and in some cases, from the possibility of recovering the catalytic promoter system used through simple procedures of work-up. One of the objectives of the modern organic synthesis concern the substitution of the chemical processes that use substances dangerous for the environment with eco-friendly methodologies. The system CeCl3·7H2O-NaI is inexpensive,
non-toxic, very stable when exposed to water and air, it is able to work under solvent-free conditions and it can be recycled. This means that it is an excellent catalyst in various reactions, contributing in this way to the development of green chemistry, in response to the
problem of environmental pollution caused by the difficulty eliminating of the organic solvents. This also means the development of new strategies for the synthesis of natural
substances and unnatural with important biological activities, it represents a field of remarkable interest and in continuing development in organic chemistry.
In the academic part of this work, we are employed about the synthesis of (+)-Furanomycin, specifically we proposed a new short synthesis of a useful intermediate, a 1,2-diprotected 2-amino-pent-4-ene-1,3-diol, starting from the inexpensive natural amino acid L-serine, and via a Gamer-type aldehyde.
In the last part, that is completely different, is performed in Goldenplast spa. This company is located in Potenza Picena (MC) and it works in the manufacturing of polymer blend for footwear market and grain as infill in artificial turf.
Goldenplast spa was founded in 1993 by Germano Ercoli, the managing director, Gianni Perozzi, the technical manager and Massimo Vallesi, the sales manager, with the scope of
thermoplastic, SBS compounds production. The production started in 1994.
The scope of Goldenplast spa is to provide footwear industry with solutions for moulding applications of soles.
During its activity, in fact, Goldenplast spa has periodically created and introduced on the market new materials which has opened to customers new work opportunities and new markets. This innovating attitude is recognised both from Goldenplast's customers and
competitors.
From 1996, with the first innovation material, called Superlight®, a low density thermoplastic rubber compound, the company introduced many other new materials up to produce a grain used like infill in artificial football fields. In 2004 this grade called Runplast® and in 2008
Runplast-2S®, with an improving formulation awards with two stars FIFA homologation.
Cause the increasing demand of high performance compounds like GPU and XP series, two family of TPU based thermoplastic rubber compounds modified with rubber resins, in 2008, the management takes decision to produce on your own TPU (Thermoplastic Poly Urethane), with the commercial name HIPUR® that begun in first months of 2009.
Nowadays, Goldenplast spa it's able to achieve a productive capacity about 150 tons a day and about 50% of this material is exported all over the world.
When plant's management begun to work on TPU project, they understood the importance they need external resources to develop this new business, completely different to the existing work activity done until now. Since the proximity of the University of Camerino, they thought to propose a long-range collaboration to solve possible problems and find out new solutions. Union among university and industry lead to a doctorate with main purpose to follow the new project until the completion and implementation in the factory.
To sum up, the second part of this PhD thesis have to be understood like not classical research approach, but in this case like a problem solving approach.


A novel neural network parallel algorithm for sorting problems is presented. The proposed algorithm using O(n/sup 2/) processors requires only two steps, and does not depend on the size of the problem, while the conventional parallel sorting algorithm using O(n) processors by F.T. Leighton (1984) needs the computation time O(log n/sup 2/). A set of simulation results substantiates the proposed algorithm. The hardware system based on the proposed parallel algorithm is also presented. >


A purification of the Neurospora protein with coal solubilization activity (CSA) using DEAE cellulose chromatography is described. The protein is heavily glycosylated suggesting that it is different than tyrosinase or common phenol oxidases even though it resembles these proteins in enzyme activity and molecular weight.


Breath holding (BH) allows to immobilize organs during radiotherapy treatment of lung cancer. Deformable registration methods applied on 3D Computerized Tomography (CT) scans acquired in BH can be used to evaluate the breath holding reproducibility. Resulting 3D vector fields could then be used to adapt internal margins for each patient. In this work we compare three non-rigid registration schemes with Gaussian, linear-elastic and Nagel-Enckelmann based regularizations. As we do not dispose of gold standard, we analyze vector fields by several operators (transitivity, symmetry, volume dilatation, Jacobian). Experiments were based on clinical data sets of two patients: one with normal lung behavior and second with lung discrepancies which lead to bad BH reproducibility. Results show that none of operators allows to clearly highlight the superiority of a method, except for convergence rapidity and Jacobian.


China has stepped into the period of building an innovative country, and Dongguan, as a famous manufacturing city, is also urgent to establish innovative cities. In this paper, nine variables are selected for the innovation development capability of each town in Dongguan. Through the principal component analysis method, combined with SPSS25.0 statistical software as the analysis tool, the development factors of 33 districts in Dongguan are compared and evaluated. Corresponding countermeasures are proposed for the existing problems.


The onset of convection in the form of magneto-inertial waves in a rotating fluid sphere permeated by a constant axial electric current is studied in this paper. Thermo-inertial convection is a distinctive flow regime on the border between rotating thermal convection and wave propagation. It occurs in astrophysical and geophysical contexts where self-sustained or external magnetic fields are commonly present. To investigate the onset of motion, a perturbation method is used here with an inviscid balance in the leading order and a buoyancy force acting against weak viscous dissipation in the next order of approximation. Analytical evaluation of constituent integral quantities is enabled by applying a Green's function method for the exact solution of the heat equation following our earlier non-magnetic analysis. Results for the case of thermally infinitely conducting boundaries and for the case of nearly thermally insulating boundaries are obtained. In both cases, explicit expressions for the dependence of the Rayleigh number on the azimuthal wavenumber are derived in the limit of high thermal diffusivity. It is found that an imposed azimuthal magnetic field exerts a stabilizing influence on the onset of inertial convection and as a consequence magneto-inertial convection with azimuthal wave number of unity is generally preferred.


This paper presents the key findings of an ESA-funded programme of work to investigate refractive systems and their application to precision polarimetry experiments. We briefly summarize the derivation of requirements on the optical system for CMB polarimetry, and the design of a refractive telescope system which meets these stringent requirements. An extensive programme of experimental work was undertaken in order to better understand the optical, thermal and mechanical characteristics of the lens material, and of lenses made from this material. A repeatable and controllable antireflection coating procedure was developed and validated, and used to coat lenses used in this study. Optical measurements before and after coating have been used to validate a new module for an industry-standard antenna modelling software package.


Informing and supporting researchers' understanding of the challenges of scholarly communication, particularly how to avoid deceptive publishing practices, remains a challenge for the academic community and its stakeholders. Over the past decade, this community has developed various strategies to assist its members in addressing this issue. However, these measures do not seem to be sufficient, and many researchers, particularly younger and less experienced ones, continue to fall prey to predatory publications. This article presents a series of workshops on scholarly communication literacy as a pedagogical strategy to raise awareness and to prevent novice researchers from falling victim to the challenges of scholarly communication and unethical publishing practices. Most participants perceived these training workshops as an effective educational approach. The results of these educational seminars demonstrate that this type of pedagogical strategy that consists of training, awareness-raising, and prevention approaches is a key factor to informing and warning novice researchers about scholarly communication pitfalls and deceptive publishing practices.

The performance of any brand can be measured by many methods. One of the widely used ways to calculate brand performance is through brand equity. Brand equity can be observed by customer's perspective as well as financial perspective. This research paper investigates the impact of advertising & promotion, research & development (R&D) and profitability (return on assets) on brand equity. In this research paper data is used from 20 international IT brands for a period of 5 years from 2011 to 2015. The results show that advertising & promotion and profitability have statistically significant impact on brand equity whereas R&D doesn't make significant impact on brand equity. Based on the findings, it is observed that advertising is having the strongest impact on brand equity.


The language style in Luxun's novels is the same as that in his essays,irony and sharp,deeply critical,full of rich thoughts and complex spirits.Lacan's psychoanalysis following Freud's doctrine put stress on linguistics.Lacan divided the subject language into four types: master discourse,college discourse,hysteria discourse,analyst discourse,discussing the paradox of the subject being social existence and self-existence.Use of his psychoanalytical discourse mode in analyzing Luxun's novel Zhu Fu enables us to understand women's oppression in the Feudal society and their existence and to know clearly speech acts of Luxun's novels.

L2/L3 forwarding requirements determine what Programmable (SDN) Networking means for transport networks. The end of Moore's law (16–7 nm silicon) and optical channel capacity (Shannon-Nyquist limits) pose constraints on hardware architectures. We look at how programmable L2/L3 SDN maps to technology contrained physical architectures.


The benefit of highly developed usability for a good acceptance of mobile devices is undisputed. The way to produce entirely satisfactory software is also well described through the principles of usability engineering. But with the outcome of new mobile technology such as tablet PCs and Smartphones in the daily business of physicians and nurses the known principles of usability engineering has to be revaluated in this context.


In a wireless power transfer (WPT) system, the power transfer efficiency (PTE) decreases sharply with the increase in transfer distance. Metamaterials (MMs) have shown great potential to enhance PTE in mid-range WPT systems. In this paper, we propose two MM slabs of a 3 × 3 array to enhance the magnetic coupling. The MM unit cell was designed by using square spiral patterns on a thin printed circuit board (PCB). Moreover, the asymmetric four-coil WPT system was designed and built based on the practical application scenario of wireless charging for unmanned devices. The simulation and experimental results show that two MM slabs can enhance power transmission capability better than one MM slab. By optimizing the position and spacing of two MM slabs, the PTE was significantly improved at a mid-range distance. The measured PTEs of a system with two MM slabs can reach 72.05%, 64.33% and 49.63% at transfer distances of 80, 100 and 120 cm. When the transfer distance is 100 cm, the PTE of a system with MMs is 33.83% higher than that without MMs. Furthermore, the receiving and load coils were integrated, and the effect of coil offset on PTE was studied.

Deep levels in iron‐doped n‐type silicon have been investigated by deep‐level transient spectroscopy (DLTS). Three deep levels of Ec−0.29 eV (E1), Ec−0.36 eV (E2), and Ec−0.48 eV (E3) were observed. The concentration of E1 and E2 levels increased during the storage at room temperature. The depth profile of the E3 level concentration indicates the out‐diffusion and precipitation of the defects related to the E3 level. In addition, after annealing at 80 °C for 30 min, the E2 and E3 concentrations decreased and then recovered at room temperature. These results suggest that the defects related to these levels are mobile during quenching and storage at room temperature. The temperature dependence of the E3 level concentration shows a formation energy of about 2 eV, which is smaller than that of interstitial iron, and the E3 level concentration is two orders of magnitude lower than the concentration of interstitial iron. The origins of these levels are probably loosely associated iron‐related complexes such as ...

Abstract - We used egg-mass counts to monitor populations of Lithobates sylvaticus (Wood Frog) and Ambystoma maculatum (Spotted Salamander) at 4 ponds located in central Vermont. We monitored numbers of egg-masses for 15 springs over the course of 20 years (2000–2020). Each year, the number of Wood Frog egg-masses at our breeding sites increased rapidly, over a period of close to 2 weeks. Spotted Salamanders deposited eggs beginning about a week later than the Wood Frogs, and the number of their egg-masses increased at our study sites over a period of up to 8 weeks. Consequently, when using egg-mass counts to determine presence/absence or to monitor populations, it is important to take the relative phenology of these 2 species into consideration.

This study investigated 2 different homogenization techniques for reducing the size of calcium alginate beads during the microencapsulation process of 8 probiotic bacteria strains, namely, Lactobacillus rhamnosus, L. salivarius, L. plantarum, L. acidophilus, L. paracasei, Bifidobacterium longum, B. lactis type Bi-04, and B. lactis type Bi-07. Two different homogenization techniques were used, namely, ultra-turrax benchtop homogenizer and Microfluidics microfluidizer. Various settings on the homogenization equipment were studied such as the number of passes, speed (rpm), duration (min), and pressure (psi). The traditional mixing method using a magnetic stirrer was used as a control. The size of microcapsules resulting from the homogenization technique, and the various settings were measured using a light microscope and a stage micrometer. The smallest capsules measuring (31.2 microm) were created with the microfluidizer using 26 passes at 1200 psi for 40 min. The greatest loss in viability of 3.21 log CFU/mL was observed when using the ultra-turrax benchtop homogenizer with a speed of 1300 rpm for 5 min. Overall, both homogenization techniques reduced capsule sizes; however, homogenization settings at high rpm also greatly reduced the viability of probiotic organisms.


This paper presents floristic and phytossociology survey, and floristic similarity between two sites of beach vegetation in Itacare and Mata de Sao Joao shores of Bahia. Twenty eight species, belonging to 15 families were identified. Poaceae and Fabaceae are the species richest families (five species each). Remirea maritima (Cyperaceae) is the most important species in both sites (IVI = 118 in the Itacare shore, and IVI = 124 in the Mata de Sao Joao shore). Itacare shore has 34.38% of exclusive species, whereas Mata de Sao Joao shore presents 43.75%. Sorensen Similarity Index (44.4%) showed that the two study areas are weakly similar. Thus, beach vegetation development is associated to coastal line stability.


Designing deep neural network models for embedded devices is a challenging task since the models need to be lightweight, fast, and accurate. This paper proposes a hardware-aware model optimization tool (HOT) to optimize a given model in terms of latency or accuracy by replacing its existing operators with the best-performing operators for target hardware. The proposed tool finds optimal operators with high accuracy and low latency in a short searching time while keeping the existing model structure rather than finding an entirely new network architecture. The result shows that the HOT improves MobileNetV2 backbone based models by up to 13.93% in accuracy (mAP) or 37.84% in latency (ms) with cascaded pyramid network (CPN) (pose estimation) and 31.03% in mAP or 56.64% in latency (ms) for single shot multi-box detector (SSD) (object detection) on digital television.


FIELD: physics. SUBSTANCE: method of measuring the gap in a plasma jet between a plasma torch and a billet in the production of metal powders and granules is proposed. In the claimed method for measuring the gap in a plasma jet between a plasma torch and a workpiece in the production of metal powders and granules, a video of the process of melting the workpiece with a digital colour FHD-camera with a black high-density filter is carried out, and the image is transferred to a computer. The obtained digital image undergoes the operations of excluding illumination, glare and redundancy by means of digital framing, filtering the blue and interactive formation of the polychrome colour profile, the subsequent conversion to the image in grayscale, binarization with a predetermined threshold, the allocation of the informative area of the black and white image for the maximum density of the pixel horizontal fill in the longitudinal-vertical plane. The obtained image is compared with the scale of the measuring calibrated dimension grid and the result of a single gap measurement is obtained. The sampling of the measurements and their statistical processing are accumulated, followed by an estimate of the average value of the gap and dispersion. EFFECT: increasing the productivity of the technological process of centrifugal spraying of the billet. 1 dwg

In this paper, we introduce some experience in a temperature screening of a mainboard.


In the presence of a rotating Kerr black hole, we investigate hydrodynamics of the massive particles and massless photons to construct relations among number density, pressure and internal energy density of the massive particles and photons around the rotating Kerr black hole and to study an accretion onto the black hole. On equatorial plane of the Kerr black hole, we investigate the bound orbits of the massive particles and photons around the black hole to produce their radial, azimuthal and precession frequencies. With these frequencies, we study the black holes GRO J1655-40 and 4U 1543-47 to explicitly obtain the radial, azimuthal and precession frequencies of the massive particles in the flow of perfect fluid. We next consider the massive particles in the stable circular orbit of radius of 1.0 ly around the supernovas SN 1979C, SN 1987A and SN 2213-1745 in the Kerr curved spacetime, and around the potential supermassive Schwarzschild black holes M87, NGC 3115, NGC 4594, NGC 3377, NGC 4258, M31, M32 and Galatic center, to estimate their radial and azimuthal frequencies, which are shown to be the same results as those in no precession motion. The photon unstable orbit is also discussed in terms of the impact parameter of the photon trajectory. Finally, on the equatorial plane of the Kerr black hole, we construct the global flat embedding structures possessing (9 + 3) dimensionalities outside and inside the event horizon of the rotating Kerr black hole. Moreover, on the plane, we investigate the warp products of the Kerr spacetime.


The coastal ecosystems of the Rio de la Plata are in a situation of increasing vulnerability. The advance of urbanization over natural spaces and the lack of adequate management have led to the loss of native species, the invasion of exotic species, the modification of spatial succession and the reduction, fragmentation and / or disappearance of these ecosystems and therefore to the loss of the services that they can provide. In this paper, the state of the natural spaces on the Punta Lara shore was characterized and evaluated. A temporary evolution evaluation of the natural riverside spaces was droven, including a description of the plant communities, the characterization of its ecological quality and surveys of the local population to know their perception and interests about the riparian space. Based on our results, a Management Proposal is presents in order to recover and preserve the riparian ecosystem.


The existence and size of a metallic core in 4 Vesta place key constraints on the asteroid's differentiation and thermal history. Because convecting cores can generate magnetic fields, remanent magnetization in planetary rocks can be used to infer past dynamo activity and therefore core formation and convection. To search for records of such a dynamo, we performed a paleomagnetic study of the Millbillillie eucrite. Our data provide the first unambiguous evidence of remanent magnetism recorded on its parent body 4 Vesta. Mutually-oriented subsamples contain at least one stable, unidirectional component of magnetization. This remanence is likely a record of crustal fields on 4 Vesta before 3.55 Ga or a dynamo field during a period of global thermal metamorphism within the first 100 Myr of formation. The intensity and acquisition timing of this remanence constrain the strength and duration of a proposed early Vesta dynamo, and have important implications for detecting crustal magnetic fields using observations of possible space weathering features by the Dawn spacecraft.


From the perspective of mainstream medicine, the author has summarized the topic in a didactically and thematically excellent way.

I wish to add the following facts, which deserve consideration:

"Abnormal intrinsic motility" is included among the pathophysiological components of chronic constipation. In order to activate or facilitate such abnormal motility, measures from conservative physical therapy or complementary medicine are available that all exert an influence on the autonomous enteric nervous system.

Such measures include colon treatment (5-point treatment according to Vogler, Kraus) and connective tissue massage as reflex zone therapy, in the sense of utilizing cutaneovisceral reflexes, as well as reflex zone therapy of the feet. The existence of reflex zones on the feet has not been neurophysiologically confirmed or proved, but last year, linked reflexes between the plantar surface and the knee were found in cats (1).

The empirical efficacy of plantar reflexology in influencing motility disorders of the gastrointestinal tract has been observed for a long time. We are currently researching this influence in a scientific study. There are data to show that reflex zone therapy of the feet improves the local circulation in the intestine when treating the zone that is associated with the colon (2).

In the context of complementary and extended complementary therapies and naturopathic treatments, moist, hot compresses on the abdominal region and osteopathic (visceral) techniques to stimulate motility and to accelerate delayed motility also deserve mention.

Patients with constipations should have the option of receiving these autoregulatory interventions.

Abstract Macrophomina phaseolina (Tassi) Goid. is found on all five crop-growing continents. In hot and dry seasons, this fungus is capable of causing considerable damage. In this study, mycelial compatibility of M. phaseolina isolates was investigated. In total the 30 samples collected were tested to examine their compatibility. The sunflower samples examined were collected in 2019 and 2020 in different regions of Hungary (29 isolates) and Slovakia (1 isolate). A total of 465 pairing tests were made with 30 isolates. The results of our examination showed incompatibility in 12 pairings. In our studies, we also measured the size of the microsclerotia of the isolates in order to determine which group they belong to. The diameter of the microsclerotia ranged from 74 to 182 μm. Based on this, microsclerotia belong to group 'C', as well as the data of previous studies in Hungary.
