Chemical modification of Norway spruce (Picea abies (L) Karst) wood with melamine formaldehyde resin

Impregnation of Norway spruce soft wood with melamine formaldehyde (MF) resin under vacuum-pressure process showed promising potential to improve number of properties, such as, dimensional stability and surface hardness. In this study, MF resin impregnated wood was evaluated at different levels of weight percent gain (WPG) compared to untreated one, mainly for dimensional stability and surface hardness. The modified wood, at 22.9 level of WPG possessed increase in dimensional stability in terms of anti-swelling efficiency and surface hardness by 17.5% and 124% over untreated, control. Chemical adherence and/or reaction takes place onto wood cell wall components other than cell lumens, which was proved by vertical density profile (VDP), UV microscopic and scanning electron microscopic (SEM) studies.

In order to study possible mediators of the vascular manifestations of passive cutaneous anaphylaxis (PCA), several arachidonic acid metabolites were injected into guinea-pig skin. SRS-A, LTB4, LTC and LTD increased vascular permeability, responses to LTs being enhanced by PGE2. Mepyramine inhibited responses to histamine, but not those to SRS-A and LTs: the latter were inhibited by the SRS-A antagonist FPL-55712. Both mepyramine and FPL-55712 exert limited inhibitory effects on vascular permeability during PCA. Leukotrienes may contribute towards vascular permeability during PCA.

The Michael reaction of enamines with nitroolefins

Abstract Several Michael reactions of enamines with nitroolefins (or their cogeners, the β-nitroalkyl acetates) are described. Reduction of the products with amalgamated aluminum leads to heterocyclic compounds, e.g. from 2-(β-nitro-α-phenylethyl)cyclohexanone (IV) to a partially hydrogenated 3-phenylindole (VII).

The establishment of reliable serological methods for cysticercosis in pigs is important for the surveillance, control and prevention of taeniosis/cysticercosis in humans as well as in pigs to prevent economic loss. Both ELISA and immunoblot using glycoproteins (GPs) purified by a single step of preparative iso-electric focusing, which are highly useful for human cysticercosis, have been applied for a serological study in pigs naturally infected with Taenia solium . All sera from pigs showed similar responses to those in human cysticercosis. Therefore, it is expected that both ELISA and immunoblots using GPs would be useful in differentiating infected pigs from uninfected ones.

SIMULTANEOUS SPECTROPHOTOMETRIC ESTIMATION OF ESOMEPRAZOLE AND NAPROXEN IN BULK AND TABLET DOSAGE FORM

Esomeprzole and naproxen are available in tablet dosage form in the ratio 1:25. Two simple, accurate, precise and economic methods; simultaneous equation method and multicomponent method have been described for the simultaneous estimation of esomeprzole and naproxen in tablet dosage form. Absorption maxima of esomeprzole and naproxen in distilled water were found to be 301.0 nm and 262.0 nm respectively. Beer’s law was obeyed in the concentration range 5-50 µg/ml for esomeprzole and 5-50 µg/ml for naproxen. The methods allow rapid analysis of binary pharmaceutical formulation with accuracy. Results of two methods were validated statistically and by recovery studies and were found to be satisfactory.

Bioavailability of potassium from controlled-release tablets with and without water loading

The relative availability of potassium from a controlled-release multiple-units tablet (Kalinorm) and a single-unit tablet (Slow-K) were compared in 13 volunteers on a low potassium diet (less than 30 mmol), by observing changes in urinary potassium excretion after administration of a single dose of 32 mmol potassium, either with or without water loading. Irrespective of procedure, the two products had the same extent of availability. The use of water loading, and special precautions about the level of dietary potassium and its composition when studying urinary potassium excretion, are discussed. It is suggested that water loading should be avoided when investigating the rate of potassium excretion.

Abstract Cation concentration profiles in solid—solution scales on NiCo alloys have been calculated by making use of Wagner's theoretical analysis. As a result of the computation method used, it becomes unnecessary to incorporate experimental values in the calculation for either the parabolic rate constant, k p , or the boundary conditions of the cation profile. The agreement between the independently determined theoretical and experimental cation profiles provides strong support for Wagner's model. The calculated variation of k p with alloy composition is also in agreement with the experimental data.

THE OXIDATION OF A COMPLEX URANIUM SALT IN ALKALINE SOLUTION

The reaction of hydrogen peroxide with U salts in the presence of an excess of alkaline carbonate produces a red-orange solution. Spectrophotometric studies indicate the formation of a peroxide complex as a result of the reaction between an H/sub 2/O/sub 2/ molecule and a U atom. The equilibrium constant, indicating the stability of the compound, was determined. (tr-auth)

Background ::: Unsaturated fatty acids (FA) are required for cancer cell growth. In normoxia cells can generate unsaturated FA from saturated stearic and palmitic acid by desaturation. However, since the desaturation step is oxygen-dependent hypoxic cancer cells display an increased dependence on the uptake of unsaturated FA. Up to now the mechanism of increased FA uptake in hypoxia is largely unknown. Here we aimed to study the role of human serum and glucocorticoid-inducible kinase (SGK1) in the regulation of FA uptake in cancer cells exposed to acute or chronic cycling hypoxia and explore its use as target for the radiosensitization of hypoxic cancer cells.

Bentiromide as a test of exocrine pancreatic function in adult patients with pancreatic exocrine insufficiency: Determination of appropriate dose and urinary collection interval

Abstract A dose-ranging crossover study of orally administered bentiromide was conducted in 47 patients with chronic pancreatic disease and 61 healthy volunteers. Four doses (100 mg, 500 mg, 1 g, and 5 g) and postdosing urine collection periods (0–3, 0–6, 0–12, and 0–24 h) were studied. Of these, the 500-mg dose and 0–6-h urine collection period afforded maximal separation of urinary arylamine excretion rates between the two populations. At this dose and collection period, the lower limit of normal (mean − 2 SD) for the control group was 57%; none of the healthy volunteers had 6-h arylamine excretion rates

Biochemistry of Halogenated Aldehydes and Ketones

The susceptibility of a halogen situated at the α position of an aldehyde or ketone to nucleophilic displacement plays a central role in much of the biochemical behavior of these compounds. Examples to be reviewed in this chapter include the reaction of α-chloro- and α-bromoaldehydes with nucleic acid components and the use of α-halocarbonyl compounds as affinity labels. The presence of halogen also affects the chemistry of the neighboring carbonyl group, making the carbonyl carbon more electrophilic, an effect especially pronounced with α-fluorine substitution. This has been used to advantage in the design of several transition state analogue enzyme inhibitors, based on the ready formation of tetrahedral intermediates from such halogen-substituted analogues.

Abstract Using multicanonical sampling, zero-temperature properties of the 3d Edwards-Anderson Ising spin glass model are studied. Finite size scaling with a zero-temperature scaling exponent y = 0.74±0.12 describes the data well. Alternatively, a descriptions in terms of Parisi mean field behavior is still possible. The two scenarios give significantly different predictions on lattices of size ≥12 3 .

In this paper we investigate the relationship between the mixing times of the Glauber dynamics of a statistical mechanical system with its thermodynamic equilibrium structure. For this we consider the mean-field Blume-Capel model, one of the simplest statistical mechanical models that exhibits the following intricate phase transition structure: within a two dimensional parameter space there exists a curve at which the model undergoes a second-order, continuous phase transition, a curve where the model undergoes a first-order, discontinuous phase transition, and a tricritical point which separates the two curves. We determine the interface between the regions of slow and rapid mixing. In order to completely determine the region of rapid mixing, we employ a novel extension of the path coupling method, successfully proving rapid mixing even in the absence of contraction between neighboring states.

We study the non-equilibrium dynamics of the spherical p-spin models in the scaling regime near the plateau and derive the corresponding scaling functions for the correlators. Our main result is that the matching between different time regimes fixes the aging function in the aging regime to h(t) = exp [t1 − μ]. The exponent μ is related to the one giving the length of the plateau. Interestingly 1 − μ is quickly very small when one goes away from the dynamic transition temperature in the glassy phase. This sheds new light on the interpretation of experiments and simulations where simple aging was found to be a reasonable but not perfect approximation, which could be attributed to the existence of a small but non-zero stretching exponent.

In agreement with experimental findings, transient phases are obtained at low temperatures. Observed structures are investigated, and the kinetics of their domain formation is described. The convergence of the system is seen to be exceptionally slow, and the rate of domain evolution is found to increase with decreasing oxygen content. The implications of these findings on the development of a complete theoretical ordering model for this system are discussed.

Structure of negatively charged muonium in n-type GaAs.

Muon level-crossing resonance and muon-spin-rotation measurements on heavily doped {ital n}-type GaAs:Si and GaAs:Te show that the majority of positive muons implanted at room temperature form an isolated diamagnetic muonium center located at a high-symmetry site with Ga neighbors along the {l_angle}111{r_angle} direction(s). These experiments, together with theoretical considerations, imply that negatively charged muonium is at or near the tetrahedral interstitial site with four Ga nearest-neighbor atoms. Except for zero-point energy differences, these results should model negatively charged isolated hydrogen in GaAs.

We find a very good description of the fine spectral features, which improves considerably over the conventional cluster model. We analyze the role of the non-local screening and its relationship to the long-range magnetic order and the lattice geometry. Our results reveal the potential of the present method for the analysis and interpretation of the modern high-energy-resolution experiments.

First-principles study on the electronic structure of bismuth transition-metal oxides

The electronic structure, magnetic and electric properties, and lattice stability of multiferroic BiMnO 3 as a typical system in perovskite Bi transition-metal oxides (BiMO 3 ) are studied from first principles. It is demonstrated theoretically for the first time that the orbital ordering within the Mn eg orbitals is actually realized in BiMnO 3 , being consistent with crystallographic data, and plays a crucial role in the appearance of ferromagnetism. Total-energy calculation shows the ferromagnetic state is indeed stabilized. Electrical polarization of BiMnO 3 is also estimated based on the Berry phase theory. Lattice instability to off-centred displacement, which is driven by strong covalent bonding between Bi 6p and O 2p states, is found to be rather common in the BiMO 3 series.

For demonstration, a planar bandpass filter (3-dB bandwidth 21.9%) was designed and fabricated.

[Circumstances of Parkinson's disease diagnosis].

Parkinson's disease is one of the most frequent neurodegenerative diseases. The usual characteristic signs combine the classical triad, rest tremor, bradykinesia and rigidity. The diagnosis is usually easy after several years, especially when the levodopa responsiveness is established, and most of the differential diagnosis can then be ruled out. However, the diagnosis of Parkinson's disease is not confirmed at autopsy in 25% of cases. The errors are much more frequent at disease onset since the clinical presentation may be insidious and may comprise non-motor signs such as pain, vegetative, sensory or neuropsychological signs. In the future, early recognition of the disease will become more and more important with the development of neuroprotective therapeutic strategies.

Abstract A simple pseudopotential (PP) model developed by us earlier was used here to study lattice dynamics and lattice statics of copper. Comparison of the accuracy attainable in different model calculations of the off-symmetry phonon frequencies was made, and the PP model appeared to be at least as accurate as the embedded atom method (EAM). We suggest that calculation of further lattice properties is necessary to evaluate any microscopic model properly. As an example we give a brief review of the PP model application in the lattice dynamics of alloys including the calculation of frequency shifts in different palladium-based alloys.

Critical dynamics of a uniaxial and dipolar ferromagnet

We study the critical dynamics of three-dimensional ferromagnets with uniaxial anisotropy by taking into account exchange and dipole-dipole interaction. The dynamic spin correlation functions and the transport coefficients are calculated within a mode coupling theory. It is found that the crossover scenario is determined by the subtle interplay between three length scales: the correlation length, the dipolar and uniaxial wave vector. We compare our theoretical findings with hyperfine interaction experiments on Gd and find quantitative agreement. This analysis allows us to identify the universality class for Gd. It also turns out that the µSR relaxation rate can be best fitted if it is assumed that muons occupy octahedral interstitials sites within the Gd lattice.

Effect of magnetic field dependent viscosity and rotation on ferroconvection saturating a porous medium in the presence of dust particles

This paper deals with the theoretical investigation of the combined effect of magnetic field dependent (MFD) viscosity and rotation on ferroconvection saturating a porous medium in the presence of dust particles subjected to a transverse uniform magnetic field. For a flat fluid layer contained between two free boundaries, an exact solution is obtained. A linear stability analysis has been carried out to study the onset of ferroconvection. The cases of stationary convection and oscillatory modes have been discussed. In this paper, an attempt is also made to obtain the sufficient conditions for the non-existence of overstability.

For Cu and Ag impurities our results point to errors of density-functional theory in estimating the d contribution to σ SO . In total a consistent interpretation of the trends is given

Magnetic Resonance Studies of Solid-State Hydrogen and Hydrogen-Related Defects

Hydrogen is a detrimental impurity in many chemical vapor deposited (CVD) materials, particularly those involved in electronic or optical applications. For example, active hydrogen defects have been observed in materials such as silicon, Si, gallium arsenide, GaAs, and diamond, C, thin films. Hydrogen and its related defects can be identified, quantified, and observed using magnetic resonance techniques. These techniques allow a unique quantitative, non-destructive view of hydrogen in the solid-state. Nuclear magnetic resonance (NMR) is used to study hydrogenated defects directly, while electron paramagnetic resonance (EPR) is used to observe hydrogen associated with paramagnetic defects. These observations can enhance our understanding of the effects of hydrogen incorporation on the properties of such materials.

Spatiotemporal modulation (STM) has emerged as a promising paradigm for the development of magnetless nonreciprocal devices, but it poses significant practical challenges when sought to be implemented over structures with a large number of modulated components, such as metasurfaces. Here it is shown that this problem may be overcome in metasurfaces biased with circular-polarized waves. In particular, it is shown that this type of biasing can create modulation equivalent to angular-momentum modulation, without any complicated modulation network. Different forms of CP modulation are discussed and shown how they can lead to different nonreciprocal functionalities, including Faraday rotation, nonreciprocal amplification and isolation.

We study in this paper the properties of a two-body random matrix ensemble for distinguishable spins. We require the ensemble to be invariant under the group of local transformations and analyze a parametrization in terms of the group parameters and the remaining parameters associated with the 'entangling' part of the interaction. We then specialize to a spin chain with nearest-neighbour interactions and numerically find a new type of quantum-phase transition related to the strength of a random external field, i.e. the time-reversal-breaking one-body interaction term.

Direct observation of ferrimagnetic/ferroelastic domain interactions in magnetite below the Verwey transition

Abstract The magnetic behaviour of magnetite at low temperatures is dominated by its transformation to a monoclinic crystal structure that is simultaneously ferrimagnetic, ferroelastic and ferroelectric below ∼ 125 K (the Verwey transition). Here we use electron microscopy to reveal the relationship between ferrimagnetic and ferroelastic domain structures in monoclinic magnetite. We present dynamic observations of magnetite during heating and cooling across the Verwey transition, revealing a diversity of unexpected interaction phenomena between crystallographic twins and magnetic domain walls. This study provides a new understanding of the low-temperature magnetic properties of magnetite that will affect a broad range of rock magnetic studies, from the interpretation of magnetic remanence in terrestrial rocks and sediments to the search for biogenic magnetite in extraterrestrial materials.

We present an electronic structure calculation of the valence band for some II--VI binary/ternary alloy interfaces. We use the empirical tight-binding method and the surface Green's function matching method. For the ternary alloys we use our previously set Hamiltonians they describe well the band gap change with composition obtained experimentally. At the interface domain, we find three non-dispersive and two interface states besides the known bulk bands. The non-dispersive states are reminiscent of the ones already obtained experimentally as well as theoretically, in (001)-oriented surfaces. We make use of the available theoretical calculations for the (001)-oriented surfaces of the binary compounds and for the binary/binary interfaces to compare our new results with.

Normal and anomalous densities in Bose–Einstein condensates with optical lattices

We study the quantum phase transition from the superfluid to the Mott insulator state in two- and three-dimensional Bose–Einstein condensate with optical lattices using Bose–Hubbard Hamiltonian within the generalized Hatree–Fock–Bogoliubov approximation. The behavior of the depletion and the anomalous fraction has been investigated in the Mott insulator phase. We found that at T = 0, these quantities become significant in two and three dimensions. It is shown also that the dimensionality of the lattice enhances the anomalous density.

Abstract A layer of random defects in the simple cubic Ising model with nearest neighbor ferromagnetic interactions of strength J is considered. Using the real space renormalization group method we calculate defect free energy in the whole temperature range. Specifically, we analyze: the layer of diluted defects, the layer of spin-glass type defects, and the layer of mixed defects. The free energy is strongly dependent on the value of couplings between the defect and the bulk.

Leigh syndrome, a mitochondrial encephalo(myo)pathy: A review of the literature

Results of a literature survey of 173 patients with Leigh syndrome are presented, with emphasis on signs and symptoms in relation to age at onset, contributions of technical investigations to the diagnosis, pathophysiology, genetic considerations and therapeutic aspects. Based on this study we are of the opinion that it is possible to come to a diagnosis of "most probable Leigh syndrome" durante vitamin on the combination of clinical signs and symptoms, autosomal recessive mode of inheritance, association with a defect of energy metabolism, and CT or MRI abnormalities.

We present a computational study of 2$p$ core-level X-ray photoemission spectra of transition metal monoxides MO (M=Ni, Co, Mn) and sesquioxides M$_2$O$_3$ (M=V, Cr, Fe) using a theoretical framework based on the local-density approximation (LDA) $+$ dynamical mean-field theory (DMFT). We find a very good description of the fine spectral features, which improves considerably over the conventional cluster model. We analyze the role of the non-local screening and its relationship to the long-range magnetic order and the lattice geometry. Our results reveal the potential of the present method for the analysis and interpretation of the modern high-energy-resolution experiments.

205Tl NMR study of vortex state of Tl2Ba2CuO6+δ

Abstract We report a 205 Tl NMR study of vortex state for an oriented polycrystalline sample of an overdoped high- T c superconductor Tl 2 Ba 2 CuO 6+δ ( T c ∼85 K) with magnetic field 2 T along the c -axis. An obvious Redfield pattern of the 205 Tl NMR spectrum for our sample at T =5 K indicates the vortex lattice state without local antiferromagnetic order at vortex cores. We emphasize that nonexponential nuclear spin-lattice relaxation curves indicate an imperfect vortex lattice or Bragg glass phase.

Ag-added Y–Ba–Cu–O bulk superconductors were joined using Ag-added Er–Ba–Cu–O solder and different Er211 contents. Microstructural analysis revealed that the volume fraction of Er211 at the joint with a composition of Er123:Er211 = 4:1 was the same as that for the expected volume fraction of the initial composition. That is, this composition seems to be optimum, since the mass balance was maintained during the crystal growth from the initial growth stage to the final stage. The trapped-field distribution for the joint using this composition was uniform and the only single peak indicated that strong coupling was achieved.

Transition Metal Complexes With Perfluorinated Ligands.

Abstract : We have continued to make progress in preparing transition metal complexes containing fluorinated ligands, and have completed several sub-projects. We have prepared the first examples of transition metal compounds containing tetrafluoroethylene ligands that rotate rapidly on the NMR time scale. This is a significant discovery en route to a transition metal catalyst that will promote the Ziegler-Natta polymerization of fluorinated olefins to give high polymers. The factors governing the barrier to fluoroolefin rotation have been identified. We have synthesized the first example of a transition metal complex containing the pentafluorocyclopentadienyl ligand. This is an important ligand that may improve the thermal robustness of many transition metal compounds. (jg)

(Received 19 June 2011 ; in final form 25 February 2012) Abstract In this study, we investigated the spin dependent electronic transport of a fishbone-like nanostructure including two magnetic atoms at its ends. The electronic conductance of this nanostructure for three different orientations of atomic magnetic moments was numerically studied when the structure was sandwiched between two nonmagnetic leads. By using Green’s function technique at the tight-binding model, we calculated the spin dependent electronic transmission coefficient. The calculated results revealed that the conductance depends on the incident electron energy as well as the magnitude and orientation of atomic magnetic moments in the nanostructure.

Fano-Rashba effect and enhancement of figure of merit and violation of Wiedemann-Franz law

Abstract In the present article, we study the spin-dependent thermoelectric properties of a quantum dot connected to two ferromagnetic contacts. We obtain results for the conductance, thermopower, thermal conductance, Lorentz ratio and figure of merit. The transmission probability shows antiresonances as a function of the energy due to the quantum interference effects. It results in a violation of the Wiedemann-Franz law which produces an improvement of the spin-dependent thermopower and the merit figure of the system. This set up can be used to design new spin-dependent thermoelectric devices with high efficiencies.

In this paper, we extend our previous template analysis of a self-exciting Faraday disc dynamo with a linear series motor to the case of a nonlinear series motor. This introduces two additional nonlinear symmetry-breaking terms into the governing dynamo equations. We investigate the consequences for the identification of a possible template on which the unstable periodic orbits (UPOs) lie. By computing Gauss linking numbers between pairs of UPOs, we show that their values are not incompatible with those for a template for the Lorenz attractor for its classic parameter values.

X-ray photoelectron spectroscopic study of the surface composition of sediment or soil models

Abstract X-ray photoelectron spectroscopy was applied to analyze the surface composition of sodium dihydrogenphosphate/ferric oxide systems and montmorillonite which were chosen as model sediment (soil) systems. Striking differences in the photoelectron emission intensities for certain elements were observed for samples of differing preparations and where the bulk composition of elements were retained. Adsorbed phosphate ion was persistent on ferric oxide surface against repeated leaching by water where sodium ion was lost completely from the surface.

Health and well-being of the homeless in South African cities and towns

Little is known about the health and well-being of people who live on the streets although their lifestyle involves health risks. This study used qualitative and quantitative methods to explore the health status and health service needs of homeless people in several South African cities and towns. It was found in some cases that their own or family members' ill-health had contributed to their homelessness. Illnesses associated with poor living conditions or lifestyles were more common in the homeless than in the general population in certain age and sex categories. Access to healthcare was generally good in urban centres and most respondents were satisfied, although some reported discriminatory treatment. The risk profile of the homeless shows that systematic health promotion is required and that some health service providers need to be made more aware of the health needs of the homeless.

The roughly 0.5-km{sup 2} (0.2-mi{sup 2}) Hanford Waste Vitrification Plant (WHVP) site is located in the Pasco Basin in south-central Washington State at the US Department of Energy`s Hanford Site. The HWVP site is planned for use as a waste treatment facility for treating the high-activity fraction of waste currently stored in underground storage tanks on the Hanford Site. In order to determine the pre-construction chemical properties of the proposed construction site soils and to enable the HWVP to segregate these, as necessary, from any impact of HWVP operations, a soil baseline sampling plan was written and implemented. The report describes the baseline sampling plan.

Advanced Coal Conversion Solid Wastes: Waste‐Management Implications

Characterization data are presented for solid wastes obtained from three advanced coal‐utilization processes and one conventional pulverized‐coal combustion process. Tables and figures summarize the data and compare the properties of the wastes. Based on the results, the impact of the advanced process wastes on the power‐production industry is examined and potentially useful waste‐management practices are evaluated. The evaluation indicated that it is possible to use conventional waste‐management technology to handle and dispose of most advanced process wastes. However, some of these wastes may present special problems. The utilization potentials of the advanced process wastes are also evaluated. It was found that some advanced process wastes may not be suitable for established fly ash uses such as cement replacement, but that they are acceptable for other uses such as fill materials, soil‐stabilization additives, and soil‐amendment activities.

Sod-podzolic soils with a complex organic profile of the southern Vyatka River basin

The article is devoted to the morphology and substantive properties of the sod- podzolic soils with a complex organic profile having the second humus horizons and found on the southern right bank of the lower Vyatka River. The research results of the mineral and organic phases are the evidence of the relict origin of the second humus horizon as well as the evidence of profile polygenicity of the given soils. They went through two fundamentally different pedogenesis stages during the postglacial period: 1) the developmental accumulative evolution stage in the first half of the Holocene and 2) the accumulative-eluvial stage of erasing evolution including the elements of inheriting evolution in the second half of the Holocene. Keywords: granulometric composition, fractional and group composition, humus age, genesis, soil evolution

ABSTRACT A field study investigated the perception of environmental hazards in residential areas polluted by chemical wastes. Soil pollution is an important problem in The Netherlands. The government expects that in the period from 1982 to 1997 some 1000 sites will need remedial action. Of these sites about 50 concern pollution in residential areas. In four cases of soil pollution experiences of the inhabitants, the information process, social and medical assistance and participation by the inhabitants are studied. The data were collected in comprehensive interviews with involved professionals, the relevant authorities and 756 inhabitants. The cases were in different stages of technical investigation and remedial action. Differences in managing approach, nature of the pollutants and age of the houses were related to the perceptions and expectations of the inhabitants. It will be argued that increased understanding of individual reactions to cases of soil pollution could have important consequences for pol...

Glides and initial vowels within the onset prominence representational environment

This paper discusses the notion of "onsets" within the Onset Prominence representational environment (OP; e.g. Schwartz 2010, 2013), with empirical focus on the representation of glides and initial vowels. Both glides and initial vowels have been shown to exhibit ambiguous behavior across languages, which has been problematic for representational theories based on a linear string of segments. The OP environment is based on a hierarchy of phonetic events, incorporating structural ambiguities that may serve as parameter settings for the dual behavior of both glides and initial vowels. This approach eliminates the need for an ONSET constraint, and offers an explicit reference point by which the concept of markedness in prosodic structure may be defined.

We study in perturbative QCD the helicity amplitudes of the process ${\ensuremath{\gamma}}^{*}\stackrel{\ensuremath{\rightarrow}}{p}\ensuremath{\rho}p$ at large virtualities Q of the photon ${\ensuremath{\gamma}}^{*}.$ We estimate all spin-flip amplitudes taking into account an important effect of the scale behavior of the gluon density. The transition of a transverse virtual photon to a longitudinal vector meson is not small at typical conditions at the DESY ep collider HERA. This helicity nonconserving amplitude leads by interference to a measurable effect in the distribution of the angle between the electron scattering and the meson production planes.

What is another term occasionally used to refer to A cappella?

A cappella [a kapˈpɛlla] (Italian for "in the manner of the chapel") music is specifically group or solo singing without instrumental accompaniment, or a piece intended to be performed in this way. It contrasts with cantata, which is accompanied singing. The term "a cappella" was originally intended to differentiate between Renaissance polyphony and Baroque concertato style. In the 19th century a renewed interest in Renaissance polyphony coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists led to the term coming to mean unaccompanied vocal music. The term is also used, albeit rarely, as a synonym for alla breve.

Short-term memory is believed to rely mostly on an acoustic code for storing information, and to a lesser extent a visual code. Conrad (1964) found that test subjects had more difficulty recalling collections of letters that were acoustically similar (e.g. E, P, D). Confusion with recalling acoustically similar letters rather than visually similar letters implies that the letters were encoded acoustically. Conrad's (1964) study, however, deals with the encoding of written text; thus, while memory of written language may rely on acoustic components, generalisations to all forms of memory cannot be made.

Phonological neighborhood density and word retrieval - An ERP study

During the process of word retrieval, words a re elicited from the mental lexicon. According to the Cohort Model, word recognition occurs when only one candidate in the cohort of possible words remains. Words are recognized via successive reductions in the number of possible word candidates as each phoneme is perceived. Each word has a particular number of neighbors, whereas a word can have dense or sparse neighborhood density (ND) depending on the number of words that sound similar to a target word. Words with dense neighborhooods are defined less accurately than words with sparse neighborhoods. Our study aimed to investigate the influence of neighborhood density in the process of spoken word and non-word retrieval using the ERP technique and expecting the N400 effect.

Discovering consistent word confusions in noise

Listeners make mistakes when communicating under adverse conditions, with overall error rates reasonably well-predicted by existing speech intelligibility metrics. However, a detailed examination of confusions made by a majority of listeners is more likely to provide insights into processes of normal word recognition. The current study measured the rate at which robust misperceptions occurred for highly-confusable words embedded in noise. In a second experiment, confusions discovered in the first listening test were subjected to a range of manipulations designed to help identify their cause. These experiments reveal that while majority confusions are quite rare, they occur sufficiently often to make large-scale discovery worthwhile. Surprisingly few misperceptions were due solely to energetic masking by the noise, suggesting that speech and noise “react” in complex ways which are not well-described by traditional masking concepts.

what is spoken language

Spoken language, is language produced by articulate sounds, as opposed to written language. Many languages have no written form, and so are only spoken.Oral language or vocal language is language produced with the vocal tract, as opposed to sign language, which is produced with the hands and face.n spoken language, much of the meaning is determined by the context. This contrasts with written language, where more of the meaning is provided directly by the text.

Language is the ability to acquire and use complex systems of communication, particularly the human ability to do so, and a language is any specific example of such a system.The scientific study of language is called linguistics.frica is home to a large number of language families, the largest of which is the Niger-Congo language family, which includes such languages as Swahili, Shona, and Yoruba. Speakers of the Niger-Congo languages account for 6.9% of the world's population.

It has traditionally focused largely on the study of the systems of phonemes in particular languages (and therefore used to be also called phonemics, or phonematics), but it may also cover any linguistic analysis either at a level beneath the word (including syllable, onset and rime, articulatory gestures, articulatory features, mora, etc.) or at all levels of language where sound is considered to be structured for conveying linguistic meaning. Phonology also includes the study of equivalent organizational systems in sign languages.

Brooke Foss Westcott (1825–1901) and Fenton J. A. Hort (1828–1892) published an edition of the New Testament in Greek in 1881. They proposed nine critical rules, including a version of Bengel's rule, "The reading is less likely to be original that shows a disposition to smooth away difficulties." They also argued that "Readings are approved or rejected by reason of the quality, and not the number, of their supporting witnesses", and that "The reading is to be preferred that most fitly explains the existence of the others."

Aside from bleeding what is an order of rules that define how pronunciation of a sound changes?

Phonology also includes topics such as phonotactics (the phonological constraints on what sounds can appear in what positions in a given language) and phonological alternation (how the pronunciation of a sound changes through the application of phonological rules, sometimes in a given order which can be feeding or bleeding,) as well as prosody, the study of suprasegmentals and topics such as stress and intonation.

Is there a place on the internet where I could find actual Star Trek episode scripts? Through the years I have purchased a few Star Trek scripts. I even have a DS9 script a buddy of mine mistakenly took off set and dazzled me with at Christmas years ago. As neat as those are to own, they are impossible to search. Is there a place on the internet where the Star Trek show or movie scripts can be obtained in digital format? (Sometimes I remember a quote and would love to find it. From time to time the internet delivers. Occasionally it does not. I want to have a resource to find quotes as I think of them.)

language analysis examples

Analysis of Language. Linguists divide the study of spoken language into two categories--phonology and grammar. Phonology is the study of sounds. Grammar is how the sounds are used to make sense. Phonology. The smallest unit of sound that can be altered to change the meaning of a word is called a phoneme. In English, for example, the words gin, kin, pin, sin, tin, and win all have different meaning due to the fact that the initial sound, or phoneme, is different.

The influence of gravity disturbance vector can't be neglected in high-precision long-time inertial navigation system (INS). In this paper, proceeding from INS arrange equations, we establish an error model of INS with gravity disturbance vector, and discuss on the basis of a case study of single channel how gravity disturbance vector influences INS in three varying situations. The simulation result indicates that the gravity disturbance vector has a conspicuous influence on high-precision long-time INS. On the basis of the comprehensive treatise of the influence of gravity disturbance vector on high-precision long-time INS, combined with the actual situation, we put forward two methods of gravity disturbance compensation.

A methodology for designing critical systems subject to magnitude- and rate-limited reference inputs is proposed. The worst-case tracking error is minimized under the constraint on the control effort. The LMI-based technique developed by Chilali and Gahinet is utilized to assign the resulting closed-loop poles into the intersection of vertical strips and a conic sector. The optimal pole region is searched by means of the simple genetic algorithm. An illustrative design example of the position control system for a two-inertia system is provided to demonstrate the proposed design methodology.

This paper proposes a robust controller design method for an norm-bounded uncertain linear system with disturbance. At First, we derive the necessary and sufficient condition for regional pole assignment for uncertain linear system, then derive the criteria of H 2 /H ∞ performance of uncertain linear system with disturbance. Hence combining them, we get the mixed H 2 /H ∞ controller control with regional assignment for norm-bounded uncertain linear system with disturbance. The problem of the robust controller designed is changed into an optimization problem, and the robust controller is parameterized by the solution of the optimization. Since the optimization problem conditions are expressed in term of linear matrix inequalities, so it makes the proposed method practical utility. Finally the numerical example illustrates the effectiveness of the proposed approach.

Smartphones may be seen as miniature toolboxes to perform Physics experiments. In this paper, we present three different “optics workbenches" mainly based on the light meter of a smartphone. One is aimed at the precise study of Malus law and other effects associated to linearly polarized light, the second allows quantifying the light intensity distribution of diffraction or interference patterns projected on a screen, and the third demonstrates the so-called inverse square law obeyed by the light from a point-like source. These experiments allow to quantitatively demonstrate three fundamental laws of optics using quite inexpensive equipment.

Pedicle violation and Navigational errors in pedicle screw insertion using the intraoperative O-arm: A preliminary report

Background ::: Use of computer-assisted insertion of pedicle screws has some advantages owing to the reportedly decreased incidence of pedicle breach and clinical events. Registration-based methods based on preoperative computed tomography imaging, 2D fluoroscopy, and 3D fluoroscopy are the most popular, however each has its limitations. O-arm–based navigation, which uses intraoperative acquisition and registration of navigated images, may overcome many of these disadvantages. We set out to study the clinical accuracy and navigational accuracy for pedicle screw insertion using our recently acquired O-arm and present our preliminary findings.

Using repeated measures to correct correlated measurement errors through orthogonal decomposition

AbstractIn a physical activity study, the 7-day physical activity log viewed as an alloyed gold standard was used to correct the measurement error in the physical activity questionnaire. Due to correlations between the errors in the two measurements, the usual regression calibration may result to a biased estimate of the calibration factor. We propose a method of removing the correlation through orthogonal decomposition of the errors, then the usual regression calibration can be applied. Simulation studies show that our method can effectively correct the bias.

A detailed 3D ankle-foot model for simulate dynamics of lower limb orthosis

The objective of this study is to develop a 3D ankle-foot model containing toe expression for designing an AFO (ankle-foot orthosis) with a training function. Two experiments were conducted to (1) show the influence of toes by comparing walking with and without an AFO, and (2) clarify the functions of toes during walking by correlating the activity of the major muscles controlling the ankle and the toes to the sole pressure data during walking. By analyzing the results of these two experiments, the necessary components and conditions of a detailed 3D foot-ankle model for developing an AFO with a training effect were clarified. A model was built and examined with empirical facts, and data were collected from the AFO simulation.

Mobile location estimation has attracted much interest over the past few years. The most challenging issues, which render to reach the required accuracy for the time-based location system, are multipath and non line-of-sight (NLOS) problems. This paper suggests the simple but robust techniques using biased Kalman filter to smooth and mitigate the NLOS effect for TOA measurements. The processed TOAs are then used for DTOA formulation and provided for location estimation. The further tracking stage is shown not to improve the accuracy much but to be necessary to smooth the mobile trajectory. The better accuracy for mobile location is suggested for future work by using the geographical information through searching the match between the path loss measured at multiple BSs and that estimated by ray-tracing techniques.

Quaternion normalization in spacecraft attitude determination

Methods are presented to normalize the attitude quaternion in two extended Kalman filters (EKF), namely, the multiplicative EKF (MEKF) and the additive EKF (AEKF). It is concluded that all the normalization methods work well and yield comparable results. In the AEKF, normalization is not essential, since the data chosen for the test do not have a rapidly varying attitude. In the MEKF, normalization is necessary to avoid divergence of the attitude estimate. All of the methods of the methods behave similarly when the spacecraft experiences low angular rates.

Quantum Mechanics at Planck scale is considered as a deformation of the conventional Quantum Mechanics.

Ranging Accuracy and Doppler Tolerance of CW Signal Based on Pseudo-Random Code Bi-Phase Modulation

Ambiguity function method is used to study the ranging and Doppler tolerance performance of CW signal based on pseudo-random code bi-phase modulation (PRCBPM). Its ranging resolution and Doppler tolerance confine are calculated, the ranging performance and Doppler tolerance capability are simulated by using the software of Matlab and the influence factors are analyzed. The simulation results are consistent with the calculation values. The results show that the ranging precision of PRCBPM signal depends on the code width and is more improved with the narrower code width, and that the Doppler tolerance performance lies on and is inverse proportion to the product of code width and code length.

AbstractAn exact solution is established pertaining to the problem of undamped free vibration of a thin circular plate resting on a Winkler foundation with variable subgrade modulus. The solution is performed by applying the infinite power series method. Moreover, the solution procedure is demonstrated through an illustrative example, wherein the general frequency equation is derived for two different boundary conditions. The correctness of the solution is also verified using results available in the literature. Finally, it is shown that the proposed method of solution is directly applicable to the more-general problem of circular plates on a variable-modulus Pasternak-type foundation.

Autoguider servo design and testing of the W. M. Keck Telescope

The servo design and model of the W. M. Keck telescopes autoguider is presented. Telescope servo models often do not include the guider loop and therefore do not take advantage of traditional control analysis and test techniques to improve performance. Guide camera dynamics, computational and transport lags, and compensation networks are discussed. A means of measuring the actual frequency response characteristics of the guide loop is presented and the results are compared to those predicted by the model. Guide performance as a function of integration time is illustrated. An improved compensation network is developed and its performance examined.© (1997) COPYRIGHT SPIE--The International Society for Optical Engineering.

A MATHEMATICAL MODEL FOR CORRECTING THE PHOTOGRAPHIC COORDINATES DUE TO ORIENTATION ERRORS (AN APPLICATION IN CLOSE RANGE PHOTOGRAMMETRY)

Photographic coordinates x and y are fundamental data in analytical photogrammetry. At the same time these coordinates are functions of interior and exterior orientation elements, and contain some errors. Therefore some corrections and reductions are applied to the image coordinates measured in comparators before they are used in mathematical models. Some corrections and reductions related to the physical error sources inherent in photogrammetric system are applied to the comparator coordinates, but any correction related to the exterior orientation elements is not applied to these coordinates. In this study, a mathematical model has been proposed to correct the photographic coordinates due to the small errors of exterior orientation elements of camera. The data obtained a close-range test field have been used in the offered mathematical model and the results have been criticized.

Effects of glucose on glycogen synthetase, phosphorylase, and glycogen deposition in the perfused rat liver.

An increase in the perfusate glucose concentration from near zero to about 11 mM increased glycogen synthesis in the perfused, isolated rat liver from zero to a value about half the maximum seen in the intact animal. Increased synthesis appeard to due not only to provision of substrate but also to conversion of glycogen synthetase to the active form and of glycogen phosphorylase to the inactive form. These glucose effects, which are apparently independent of changes in levels of hormones or adenosine 3':5'-cyclic phosphate, may be physiologically significant for control of the blood glucose level.

A recurring problem in forensic medicine is the need to fix the time of death within the limits of probability. Errors in overestimating and underestimating the post-mortem interval based on body cooling is common. Post-mortem biochemistry has become a potent additional procedure in forensic death investigation. However, in our experiment, to determine the post-mortem interval we investigated the ATPase activity. The investigation was performed on the liver tissue of 25 corpses (21 men and four women) of age ranging between 40–60 years. The study of ATPase enzymatic activity shows that there is a considerable drop in the levels of ATPase activity with increasing post-mortem interval up to 24 h and this is one of the most reliable methods for estimating time of death.
