Non-orthogonal transmission, although not entirely new to the wireless industry, is gaining more attention due to its promised throughput gain and unique capability to support a large number of simultaneous transmissions within limited resources. In this article, several key techniques for non-orthogonal transmission are discussed. The downlink technique is featured by MUST, which is being specified in 3GPP for mobile broadband services. In the uplink, grantfree schemes such as multi-user shared access and sparse code multiple access, are promising in supporting massive machine-type communication services. The multi-antenna aspect is also addressed in the context of MUST, showing that MIMO technology and non-orthogonal transmission can be used jointly to provide combined gain.


Digital transformation has become an important engine for economic high-quality development and environment high-level protection. However, green total factor productivity (GTFP), as an indicator that comprehensively reflects economic and environmental benefits, there is a lack of studies that analyze the effect of digital transformation on heavily polluting enterprises' GTFP from a micro perspective, and its impact mechanism is still unclear. Therefore, we aim to study the impact of digital transformation on heavily polluting enterprises' GTFP and its mechanism, and explore the heterogeneity of its impact.We use Chinese A-share listed enterprises in the heavily polluting industry data from 2007 to 2019, measure enterprise digital transformation indicator using text analysis, and measure enterprise GTFP indicator using the GML index based on SBM directional distance function, to investigate the impact of digital transformation on heavily polluting enterprises' GTFP.Digital transformation can significantly enhance heavily polluting enterprises' GTFP, and this finding still holds after considering the endogenous problem and conducting robustness tests. Digital transformation can enhance heavily polluting enterprises' GTFP by promoting green innovation, improving management efficiency, and reducing external transaction costs. The improvement role of digital transformation on heavily polluting enterprises' GTFP is more obvious in the samples of non-state-owned enterprises, non-high-tech industries, and the eastern region. Compared with blockchain technology, artificial intelligence technology, cloud computing technology, big data technology, and digital technology application can significantly improve heavily polluting enterprises' GTFP.Our paper breaks through the limitations of existing research, which not only theoretically enriches the literature related to digital transformation and GTFP, but also practically provides policy implications for continuously promoting heavily polluting enterprises' digital transformation and facilitating their high-quality development.


Brain is the most complex organ amongst all the systems in human body. The study of the electrical signals produced by neural activities of human brain is called Electroencephalogram. Electroencephalogram (EEG) is a technique which is used to identify the neurological disorder of brain. Epilepsy is one of the most common neurological disorders of brain. Epilepsy needs to be detected efficiently using required EEG feature extraction such as: mean, standard deviation, median, entropy, kurtosis and skewness etc. The framework of proposed technique is an efficient EEG signal classification approach. The proposed approach is used to classify the EEG signal into two classes: epileptic seizure or not. Extraction of the features by applying Discrete Wavelet Transform (DWT) in order to decompose the EEG signals into sub-bands. These features, extracted from details and approximation coefficients of DWT sub-bands, are used as input to Principal Component Analysis (PCA). The classification is based on reducing the feature dimension using PCA and deriving the Support Vector Machine (SVM), neural network analysis (NNA) and k-nearest neighbour (K-NN). In classification of normal and epileptic, results obtained exhibited an accuracy of 100% by applying NNA and k-NN. It has been found that the computation time of NNA classifier is lesser than SVM and k-NN to provide 100% accuracy. So, the detection of an epileptic seizure based on DWT statistical features using NNA classifiers is more suitable in real time for a reliable, automatic epileptic seizure detection system to enhance the patient's care and the quality of life.


Abstract It has been 6 years since the last pronounced case of an "explosive" stratospheric warming was observed over Berlin. This stratospheric warming began over southeastern Europe on 20 January 1958, a few days after a considerable increase in the drag of the satellite Sputnik β1, 1957 (II). The warming of the 25-mb surface reached its greatest intensity over the North Sea on 25 January, and the highest temperature was measured over Iceland on 30 January 1958. The warming continued to spread upstream in a westerly and northwesterly direction, crossed northern North America and finally dissolved over the northern Pacific. During the same period a second warming moved from the Aleutian Islands across Siberia to northern Europe and Greenland. The associated high-level pressure rise, were followed by surface highs a few days later. About half a year later, a few days after the very strong solar flare of 7 July 1958 and simultaneously with a remarkable increase on the drag of Sputnik III, a first summerly ...


The Enguri dam is situated in the Enguri River in the west part of Georgia and is the largest arch dam in the world. The structure is 271,5 m tall, 750 m wide, the dam body has a volume of 4 millions of cubic meters and the volume of the basin is about 1,1 billions of cubic meters, it is linked to a high pressure tunnel with a diameter of 9,5 meters and a length of 14,5 km and is equipped with 5 x 275 MW generators unit, Francis type. The construction started in the late 70's and the dam entered in temporary operation in the year 1978 and was finished in the year 1987. The dam crosses a valley formed by fractured limestone and interested by an important fault, the area has also a seismic activity.


Although recent statistics from the National Institute on Drug Abuse (NIDA) have shown a downward trend over the last several years in patterns of recent or lifetime methamphetamine use and abuse, the problem continues to be a priority public health issue in the US. Among the nearly one million visits to emergency departments in 2009 that were drug and alcohol related, approximately 10% involved the illicit use of stimulants (NIDA, May 2011). Of those who were treated in 2008 for chemical dependency in publicly funded treatment programs, approximately 10% were addicted to stimulants, with methamphetamine dependence comprising the majority of these cases (NIDA, March 2011). According to the NIDA (2005), patterns of methamphetamine abuse are becoming less clustered and more widely distributed geographically, and the demographic profi le of methamphetamine abusers is becoming less homogenous than ever before. Methamphetamine is a highly addictive drug of abuse because of its ability to easily cross the blood brain barrier to produce its " high " through dopaminergic activation in the mesolimbic pathway (NIDA, 2005; Stahl, 2008). Methamphetamine also produces a more sustained and intense euphoria or " high " than many other psychostimulants due to a longer half-life in vivo (NIDA, 2005). The neurotoxic effects of methamphetamine and other stimulants can result in long-term physiological and psychological sequelae that include neurodegenerative changes and neurotransmitter dysregulation, and these changes are clinically manifested among abusers as loss of cognition, perceptual disturbances, mood alterations, and dependence (NIDA, 2005). Treatment for methamphetamine and other stimulant dependence has primarily relied on behavioral modalities to date, given the limited research data on pharmacological treatment options to reduce abuse and to support abstinence (NIDA, 2005). In response to major public health concerns and the lack of available pharmacological treatment options for methamphetamine dependence, the NIDA issued a report to Congress in 2005 reaffi rming the agency ' s continued support for clinical drug trials and other research on the epidemiology, neurobiology, prevention, and behavioral treatment of methamphetamine dependence. The purpose of this review is to examine new research developments that have emerged in the treatment of stimulant abuse since the NIDA-issued report in 2005. Hopefully, these studies will begin to bridge the gap in effective treatment options for methamphetamine and other stimulant dependence. An overview of four research studies with multi-faceted approaches to assessment and treatment will be presented, along with a discussion of clinical signifi cance and implications for practice.


Observations of mesospheric OH(6,2) temperatures by the Utah State University Mesospheric Temperature Mapper located at Cerro Pachon, Chile (30.3°S, 70.7°S) reveal a large range of nightly variations induced by atmospheric gravity waves and tides, as well as strong seasonal oscillations. Comparative studies with other data sets including the satellite-borne SABER instrument show good agreement on nightly, as well as seasonal, temperature measurements.

CONCLUSION
Immunosuppressive treatment must be used on all cases of sympathetic ophthalmia with the goal of improving visual prognosis.


This paper addresses the model reference fuzzy tracking control design for a class of uncertain singularly perturbed nonlinear (USPN) systems. Based on the Lyapunov stability theorem and the tool of linear matrix inequality (LMI), we solve fuzzy controller gain matrices and some common positive-definite matrices and then two sufficient conditions are derived to stabilize the USPN systems. The allowable perturbation bound ε* can be determined via some algebra inequalities, such that the proposed model reference fuzzy tracking control design will stabilize the USPN systems for all εϵ(0, ε*). A practical nonlinear circuit system is given to illustrate the validity of the proposed scheme.

Tourism is a dynamic and one of the most profitable sectors for the world economy as well as for many developing countries like Bangladesh. Bangladesh has so many natural, cultural, historical, archeological, religious and man-made tourist destinations. By visiting this country one can get the opportunity to know about the tribal people, their unique culture, traditions, food habit, wildlife of various species and also can enjoy diversified tourism-related activities like water skiing, river cruising, hiking, rowing, yachting, kidding, sea bathing etc. Tourism industry is considered as a growing industry for many developing countries. It plays a significant role directly and indirectly in the GDP growth rate of Bangladesh by creating new employment opportunities for both male and female, alleviating poverty, enhancing local community participation, earning foreign currency via foreign tourists, improving the economic standards of locals, making people economically and socially stable. This research is carried out based on the qualitative approach.


The effect of GABA upon the nervous system in general, and especially upon isolated structures (i.e. cell body, axon, dendrite, receptors etc.) has been intensely studied. Topical GABA application leads to an increase in the threshold of evoked potential responses of nervous cells and receptors, while it does not affect axonal conduction.' The main site of action is believed to be a t the cell body and dendrite. The C N S GABA level is determined by the balance between formation (decarboxylation of glutamic acid) and utilization (transamination). During the latter, GABA is introduced into the Krebs cycle. An increase in GABA level leads to decreased C N S excitability with an increase in the convulsion-inducing threshold. On the other hand, decreased GABA level induces convulsions due to a lowered convulsion-inducing threshold.2 The protective effect of GABA has been demonstrated in a number of experimental and clinical convulsive states. GABA effects upon processes of higher nervous activity have been studied to a lesser extent. This is probably due to the impossibility of maintaining an increased or decreased GABA level in C N S long enough without affecting other C N S functions and because of the toxicity per se of substances that affect the GABA level. The majority of researchers believes that GABA effects are a result of its generalized hyperpolarizing action and not its specific inhibitory a ~ t i o n . ~ Iontophoretic application of GABA into the spinal and higher neural structure neurons supports this view, although a number of electrographical observations implicates marked inhibitory action.' Consideration of influence of GABA on higher nervous activities is studied in the performance of conditioned reflex behaviors in teleosts.


The differences between the U.S. war in Vietnam and the U.S. war in Iraq are vast, and the contributors to this collection of essays acknowledge and list many of them — the totally different international context, the nature of the insurgency, the scale and methods of the U.S. intervention, among others. One might conclude, therefore, that a book called Vietnam in Iraq would not have much to say. But in fact, the articles gathered here provide a provocative consideration of some of the ways in which the earlier war influences the current conflict and present some intriguing parallels, comparisons, and connections between the two. The eleven authors do not put forward a uniform view and the topics they cover are not carefully distinct from one another. Though the book has a 2007 copyright date, most of the pieces seem to have been completed in 2005. Here I will comment on just a few of the book's important themes. The Vietnam war profoundly affected the Iraq war because the former, as a key watershed event in world politics, helped define the nature of all subsequent U.S. foreign policy. Many of the authors in the book note that one of the most important legacies of Vietnam was the "Vietnam syndrome," a skepticism about the efficacy and justice of U.S. military intervention abroad. To U.S. officials — especially, but not confined to, the neoconservatives — stanching and reversing this syndrome became one of their major foreign policy goals. It was a goal for Kissinger as early as May 1975, when, as David Ryan notes, he ordered unnecessary military action in the Mayaguez incident (114, 123). It was an independent motive for going to war against Iraq in 1991 for Bush senior, who gushed afterwards that the Vietnam syndrome had finally been kicked. (His pronouncement was somewhat premature, Jon Roper notes [152]: Saddam Hussein remained in power precisely because of the syndrome.) And it was an independent motive for the 2003 Iraq war as well. The United States has to be prepared to "act decisively to use the force necessary to prevail, plus some," in Rumsfeld's words. (The Bush administration's approach to these matters was foreshadowed, Lloyd C. Gardner reminds us, in the 1992 Defense Guidance supervised by Paul Wolfowitz, then an aide to Secretary of Defense Dick Cheney [11].) Several of the authors point out that the current Iraq debacle may in fact exacerbate the Vietnam syndrome, which would be one of the few bright spots to emerge from the daily cataclysm that is Iraq.

The stress-strain curves of the fabric flexible composites and the soft tissues under various biaxial loads appear to be similar. They all contain curved fibers in soft matrices. Because of the curved fibers, inhomogeneous deformation occurs within the material. Most researchers believe that the uniaxial data cannot be used to characterize multiaxial behavior of the soft tissues in general. The constitutive equation obtained using data regression method usually gives a good description of the stress-strain behavior for the homogeneous material. It gives no physical meaning of these input values obtained for the soft tissues. Thus, these constitutive relations are highly dependent on the experimental procedure and cannot be generalized.

This paper argues that QCA is a suitable methodological choice for the analysis of a specific but widely used form of large-N data in the social sciences, namely survey data collected through computer-assisted telephone interviews or internet surveys. The reason is that the linguistic form of survey data often lends itself to a direct translation into fuzzy sets. Likert-scaled survey items let respondents make qualitative statements of agreement, disagreement and indifference. Fuzzy sets can capture these qualitative differences in a way that classical interval- scaled indicators cannot. Moreover, fuzzy algebra allows researchers to combine multiple sets in a simple and transparent manner, thereby giving QCA an important advantage over regression-based approaches. However, the analysis of large-N survey data removes one of the characteristic strengths of QCA: its case orientation. In the case of large-N survey data, the case orientation is typically weak and causal inference thus questionable. To remedy this shortcoming QCA methodologists have suggested robustness tests to enhance confidence in the proposed relationships. This paper shows how these robustness tests can be used in a large-N setting and suggests a new robustness test that is particularly suited for large-N survey data.


Numerous recent studies have suggested a possible link between childhood sexual abuse and adult psychiatric disorders. However, these studies must be interpreted with careful attention to the problems of selection bias, information bias, and the effects of confounding variables. To our knowledge, no available studies in the scientific literature have adequately controlled for all three of these sources of error. Indeed, many published studies are so vulnerable to these forms of error that they are rendered almost valueless. Therefore at present we cannot reasonably conclude whether childhood sexual abuse is, or is not, an etiologic factor in adult psychiatric disorders.


Minor differences in the vibration characteristics of a vehicle may greatly influence the comfort experienced by the driver. Therefore, such characteristics are significant in the process of vehicle development. In this experimental study, just-noticeable differences were determined for sinusoidal vertical whole-body vibrations at the frequencies 1.3 Hz and 6.0 Hz, and for the vibration amplitudes 0.2 m/s², 0.5 m/s² and 1.2 m/s². The stimulation set up was realised using a test rig constituting a seating position similar to that in a real vehicle environment. A transformed one-up-three-down method, in conjunction with a two-interval forced choice procedure, was used to determine difference thresholds, in accordance with Weber's Law, for 14 test subjects. Median relative difference thresholds in the range of 6.7% to 11.0% were observed, and were examined for statistical significance (α < 0.05) and practical importance on amplitude and frequency, with respect to this law. The results showed a frequency-dependence at the lowest vibration amplitude and an amplitude-dependence for both frequencies from a statistical point of view. However, the amplitude-dependence at 6.0 Hz was considered as negligible for practical use.


If (X; Y) 2 A D A is a pair of random variables with probability P , where A is a nite alphabet and D an integer, we consider the problem of estimating P (Y jX) when a data set (Xi; Yi) n i=1 of i.i.d variables is observed. Introducing a family of possible regression models, we build various adaptive estimators based on this family, whose risks in terms of conditional Kullback-Leibler divergence converges toward the smallest risk of the family considered at a rate that can be of the order of the minimax rate for the best model. We focus on the case when the number of observations is too small to estimate accurately all models, and introduce several estimators for dealing with such situations. The models considered are based on regression trees, leading to eecient implementations thanks to the use of a context tree and recursive computations. Their use for modeling texts written in natural language is suggested through an experiment of text clustering.


We develop a simple model that links the adoption of a productivity-enhancing technology to increased vertical integration and a less skilled workforce. We test the model's key prediction using novel microdata on vehicle ownership patterns from the Economic Census during a period when computerized dispatching systems were first adopted by taxicab firms. Controlling for time-invariant firm-specific effects, firms increase the proportion of taxicabs under fleet ownership by 12% when they adopt new computerized dispatching systems. An instrumental variables analysis suggests that the link between dispatching technology and vertical integration is causal. These findings suggest that increasing a firm's productivity can lead to increased vertical integration, even in the absence of asset specificity.

The crystallization of the r-phase of ammonium pentaborate tetrahydrate by slow evaporation at room temperature (Domenech, 1981)is linked to the presence in the solution of NH4MgCla.6H20. A structural and morphological study of the title compound has been carried out in order to obtain crystallographic data to determine the possible influence of this compound on the obtention of different phases of ammonium pentaborate tetrahydrate. Experimental. Colourless hygroscopic crystals were obtained by fractional crystallization and slow evaporation from a solution of NHa, HaBO 3 and MgC1E.6H20 in water. In the first crystallization crystals of the r-phase of ammonium pentaborate tetrahydrate were separated. In the second, crystals of the title compound were obtained.

Magnetoresistance measurements on 1000-ppm CuMn mesoscopic spin-glass samples reveal phase-coherent electron propagation on 0.4 μm length scales observed as conductance fluctuations and Aharonov-Bohm resistance oscillations. Exploiting the broken time-reversal symmetry of the spin-glass state, a unique magnetofingerprint of the specific frozen spin configuration is extracted from a pair of resistance measurements. These «spin-glass fingerprints» are manifestly different after several thermal histories, but are surprisingly robust upon field cycling to over 9 times the typical exchange field

The thermodynamic system of a human organism is subjected to the laws of thermodynamics which stable Internal Energy (U) and Internal Medium are suppoted by Internal Works (Wint) and External Works (Wext) of an organism according to first law of thermodynamics. Just both Internal Works (Wint) and External Works (Wext) of an organism are carried out by driving mechanisms cellular cycles of cells in all organs of an organism. Thus driving mechanisms cellular cycles of an open non equilibrium non linear thermodynamic system of a human organism and of the organism's organs in norm and in different pathologies are exerted by driving mechanisms of cells' cellular cycles of an organism's tissues in different organs which are studied both in norm and in cancer pathology. Besides there are studied genetic development of an organism's cells from embryonic single cell state to old aged organism from the point of view of thermodynamics. Also it is studied the influences of driving mechanisms cells' cellular cycles on mechanisms both cells development and an organism development. Moreover there are studied differences driving mechanisms of cellular cycles in different tissues of different organs. Furthermore there are compared driving mechanisms cellular cycles both Viral haploid cellular cycle and Human diploid cellular cycle. Besides there are described transmutation driving mechanisms of healthy genomic cellular cycle into cancer genomic cellular cycle from the point of view of thermodynamics. Also there are discussed driving mechanisms of cellular cycle from point of views of thermodynamics, biophysics and biochemistry


Construction of motorways and road traffic bring a new line element into the landscape, which fundamentally influences the local hydrological regime and water quality. Impermeable surfaces are introduced into the landscape, affecting the natural infiltration of water in the environment. The aim of the present research was to assess the long-term historical development of changes in the landscape retention potential due to construction of the D1 motorway in the Jihlava region and also evaluate the impact of winter maintenance on the quality of surface waters and soils. During the reference period, the research area showed an increase in land take and related increases in soil sealing by impermeable surfaces due to the construction of the D1 motorway. This fact has clearly contributed to the deterioration of the retention potential of the landscape in the area. Chloride concentrations of both matrices were evaluated in relation to the amount of de-icing salt applied at the sites and precipitation recorded in this region. Water samples collected at the outflow contained in all cases higher concentrations of chloride than samples of the inflow water. The highest chloride concentration in soil was measured in samples collected at a distance of 2 m from the road.

Health equipment in hospitals determines the productivity of health service delivery. Medical equipment must continue to function properly. One way to measure the success of maintaining medical devices is by standard Breakdown Time. This study aims to determine the application of standard Breakdown Time on damaged medical devices. The research method used is a descriptive qualitative method with in-depth interviews. There are interviewees with private status and ASN (government employees). From the private sector, there are consultants, technical managers, and administrators of professional organizations in the field of medical equipment. Interviewees with ASN status are practitioners of maintenance and repair of health equipment in government hospitals. The results of the interviews were compiled into 6 groups based on the main questions asked, then analyses descriptively. The results of the study, Standard Breakdown Time have not been applied comprehensively in hospitals. Several informants informed that although there is an application of breakdown time, the standard is not yet clear and is only applied to high-tech equipment and/or for a minimal number of equipment there is only one in the hospital. For other equipment, there is no standard when the damage occurs, until when the damaged equipment must be able to function again. In conclusion, the Standard Breakdown Time for medical devices is important and its application must be supported by Ministerial-level regulations.


In the summer of 1995, Thomas W. Parham went to his physician, Peter Arcan, for an ordinary check up. During his visit, Dr. Arcan suggested that Mr. Parham join a clinical trial studying a new drug to shrink enlarged prostates. Mr. Parham was confused because he never had prostate problems, but Dr. Arcan stated that the drug might prevent future difficulties. When asked why he joined the study, Mr. Parham stated, "I just followed his advice, just like if he said to take two aspirin instead of one. He's a doctor and I'm not." Mr. Parham should not have been entered into the study because he had been hospitalized a year earlier due to a chronic slow heart rate, a clear study-exclusion criterion that would disqualify him from being a subject in the protocol. However, Dr. Arcan sought an exemption from the drug company stating that Mr. Parham's heart rate was only "mildly slow," failing to report the prior hospitalization. After Mr. Parham began taking the study medication, he complained of fatigue, a symptom of a slow heart rate. Within weeks, after requesting to be taken off the study, he was hospitalized and a pacemaker was implanted for his slow heart rate. The drug's manufacturer, SmithKline Beecham P.L.C., was paying Dr. Arcan $1,610 for each patient enrolled in the study. The fee covered study expenses, but was sufficient to give the recruiting physician a profit for each subject enrolled.

Benign prostatic hyperplasia (BPH) and associated lower urinary tract symptoms (LUTS) are common conditions. Little is known about their etiologies except that studies have suggested a substantial heritable component. Our objective is to provide a comprehensive, genome‐wide evaluation of inherited risks and possible mechanisms of etiology in BPH.


Pervasive information visualization and interaction are fundamental tools to support learning in smart cities (SCL), for example to promote sustainable behaviours and social interaction. Building on a review of existing work, we identify the main limitations of traditional approaches based on large displays and smart-phones apps, first from a technological point of view then connecting to implications for design, user interaction and experience. In the paper we propose a set of authoring primitives at different semantic levels, ranging from more generic inter-net of things (IoT) primitives to more domain specific approaches connected to learning in SCL applications. We focus more in detail on new design opportunities, developing possible scenarios of interest that involve SCL. The use of a toolkit for rapid prototyping is proposed as a valuable support instrument for application design and development .


The post-apocalyptic world of the Fallout series is home to an array of mutated creatures, including 'super mutants', humans that have been mutated to be much larger and stronger. The biggest of these is the super mutant behemoth, which can grow to gargantuan sizes, run very fast and perform acts of incredible strength. This paper investigates the viability of such a creature existing, using dimensional analysis to determine what would happen if an ordinary super mutant were scaled up to the size of a behemoth. First the relative strength of the behemoth was estimated, then the effects of gravity on such a creature were discussed. It was found that the behemoth represented in-game would find it very difficult to survive in reality.


The utility model discloses a hot-air stirring reaction device. The hot-air stirring reaction device comprises a vertical cylinder, wherein a vertical stirring rod is arranged in the cylinder; stirring blades are arranged on the stirring rod; a hollow layer is arranged in the cylinder; a hot-air pipe communicated with the hollow layer is arranged on the cylinder; air outlet pipes communicated with the hollow layer are formed on the inner wall of the cylinder. Due to the fact that the air outlet pipes communicated with the hollow layer are formed on the inner wall of the cylinder, heated air is fed through the hot-air pipe, hot air enters the cylinder from the air outlet pipes, and raw materials in the cylinder are heated and insulated by the hot air and can be stirred and mixed by virtue of the hot air. Compared with the effect of stirring and mixing by virtue of only the stirring blades, the effect of the hot-air stirring reaction device is better. In addition, due to the fact that the air outlet pipes are arranged on the inner wall, a lump attached to the inner wall can be blown down by virtue of the hot air of the air outlet pipes. Finally, due to the fact that the hollow layer is formed on the inner wall of the cylinder, the hot air flows through the hollow layer and insulates the raw materials in the cylinder.


Abstract : A series of Advanced Reduced Scale Fuel System Simulator (ARSFSS) Runs evaluating the impact of Fatty Acid Methyl Esters (FAME) contamination on the thermal stability of a Jet A additized with a military package of additives, a JP-8 and a JP-5, were accomplished. BFA wetted-wall temperature change profiles were obtained and carbon deposition was measured. It is therefore generally concluded that FAME has no significant impact on either Jet A with the military package of additives or JP-8 or JP-5, although the data is less conclusive for the JP-5 than for the Jet A with the military package of additives and the JP-8.
