Abstract : The Telemetry Transducer Handbook was prepared in an effort to present information and data useful to the transducer user. The characteristics are discussed of the transmission system and its relation to transducers and telemetry systems. A guide is presented to more specialized investigation of the many aspects of telemetry systems. The fundamentals involved in various physical measurements and how these fundamentals are employed in the general design of transducers are presented. Measurements of displacement, strain, pressure, fluid flow, rotary speed, fuel quantity, ac power, acceleration, temperature, shock and vibration and thrust are discussed. General information and examples in the application of telemetry transducers are presented. Testing and calibration techniques and facilities available are also presented. A list of performance reports available from NBS offers some evaluation information on telemetry transducers. An extensive bibliography is presented with 835 listings. An index to the bibliography is also included.


Dasgupta et al. present a well-conceived technical study that seeks to resolve the paramagnetic NMR spectrum of the trinuclear copper centre in the small laccase from S. coelicolor. I judge their analysis and interpretation to be sound and correct. The work reported appears to be a follow-on to work reported by the same authors in Biophys. J. 119, 9-14, 2020. To an outsider in this area, it would be useful to have some explicit discussion about how this previous report links into the present work.


Electric utility demand-side management (DSM) programs affect the efficiency and timing of customer electricity use. As the number and cost of these programs increase, evaluations will become increasingly important. A key challenge is the role of evaluation in determining the amount of financial incentive that a utility earns for its DSM programs. Most regulatory incen tives for DSM programs depend on the net benefits provided by these programs. The total benefit is the reductions in electricity use and demand multiplied by the appropriate avoided costs (energy or capacity). The net benefit is the difference between total benefit and program cost. Evaluations determine the total benefits of DSM programs. This article presents a hypothetical example of problems that might arise when evaluations are subject to litigation, a likely occurrence when utility earnings depend on evaluation results. A hypothetical illustration is used because such incentives are so new that they have yet to be tested in regulatory proceedings. Possible resolutions to the problems raised by the hypothetical example are discussed.


Abstract The investigation dealt with the fabrication of β-tricalcium phosphate (β-TCP) coating layer on titanium through electrochemical reactions using micro-arc oxidation (MAO) technique. For this purpose, MAO coatings of titanium samples were carried out in the electrolyte containing hydroxyapatite (HA) particles together with various concentrations of tripotassium phosphate (K3PO4). After MAO coating, the average size of the micropores increased as the concentration of K3PO4 increased since higher concentration of K3PO4 might trigger the electrophoretic migration of HA particles incorporated into the coating layer. The X-ray diffraction patterns of the sample coated in the electrolyte with 0·2M K3PO4 exhibited the peaks of β-TCP and TiO2 compounds, whereas the other samples showed α-TCP, HA and TiO2 compounds. This phenomenon was discussed by taking the micro-arc temperature during MAO coating into account.


This paper have pondered over the condition of evaluation for research achievements on humanity and social sciences. We should put important on the data development of the evaluation information for not only scientometric evaluation but also peer review. Purifying the science environment must start from the peer review and it's mechanism for publishing paper. Novel consulting of social science achievements could help us to evaluation innovation of research achievements.


Guatemalan author Rodrigo Rey Rosa's first novella, Cárcel de árboles (1991), tells the story of a secret politico-medical experiment conducted on prisoners who have been condemned to death by the State. The experiment takes place in a prison camp located in the tropical forest. In this article, I examine the portrayal of power and embodiment in Rey Rosa's novella, placing the text in dialogue with thanatopolitical theory and outlining the ways it evokes the historical context of violence and economic transition in Guatemala. I commence by discussing the forms of power at work in the novella's prison camp, before examining the significance of medical science to Rey Rosa's depiction of embodiment. I then explore the complex aesthetic and ethical questions embedded in the relationship between language, textuality and the body in the novella. Finally, I discuss the post-human dimensions of the text that emerge in the relationship between the human bodies of the prisoners and the non-human terrain. Over the course of this analysis, I contend that Rey Rosa marshals the body to invoke the ways in which the category of the 'human' is formed, deconstructed and reconfigured in the face of the destructive power that operates in the modern techno-scientific epoch.

Unsteady flows around flapping airfoils are simulated at low Reynolds number,by solving incompressible Navier-Stokes based on pseudo compressibility method.The effect of maximum thickness variations is investigated using uncambered NACA four-digit airfoils range from 4% to 12% thickness.For pure pitching motion,the results show that average drag coefficient decreases as airfoil thickness is reduced.But for pure plunging motion,it was found that the thickness variations have a different effect on aerodynamic performance compared with that of pitching motion.Average drag coefficient increases as airfoil thickness is reduced.An analysis of periodic flow streamlines shows that it is probably due to the effect of leading edge vortex.As airfoil thickness is increased,the average pressure drag,affected by leading edge vortex is reduced even to be negative,and meanwhile friction has little increase.For Reynolds-number,as it increases,average drag coefficient is reduced slowly.The research work of this paper is expected to be useful for the design of flapping micro air vehicles.

After briefly abstracting Dr. W. Busch's description of the early stages in the growth of the young of Comatula, the author details his own observations, carried on during the last four years, on the development and subsequent changes of the larva. After complete segmentation of the yelk, a more consistent nucleus appears within the mulberry mass still contained within the vitelline membrane. The external more transparent flocculent portion of the yelk liquefies and is absorbed into this nucleus, which gradually assumes the form of the embryo larva, a granular cylinder contracted at either end and girded with four transverse bands of cilia.


With the advantage of high energy density, long cycle life and environmental friendliness, Lithium-ion battery has become a promising power source for hybrid and electric vehicles, which are liable to two kinds of failure, overcharge and overdischarge. Because of the capability of detecting multiple faults, Multiple Model Adaptive Estimation (MMAE) method was applied to a model-based fault detection of a lithium-ion battery with a two-order linear electrical model. Parameters that represent normal-mode and faulty-mode of the battery were obtained by a series of experiments, and three Kalman filters were designed thereafter. Finally, simulation verified the performance of the MMAE algorithm on fault detection of these two kinds of fault and it is shown that this technique is able to discern these faults rapidly and accurately.


Plasma triiodothyronine (T,) and thyroxine (T4) levels, as well as thyroid free (f) and bound (b) thyroid hormones (TH) content, were determined by radioimmunoassay (RIA) in adult Ranu gereri frogs during a 24 h cycle in winter, spring, summer, and autumn. Significant daily changes in plasma Tj levels were present in all the seasons except for winter, being the lowest values observed during the scotophase. In contrast, plasma T4 only showed significant changes in spring, following a similar pattern to the one described for T3. Thyroid fT3 content did present day/night significant changes only in spring showing high contents at early scotophase. Mean fT4 content was higher at the beginning of light phase than during the rest of daily photocycle in spring and autumn, but significant differences appeared only in autumn. Regarding the thyroid bound content of TH, bT1, and bT4 presented significant daily changes in spring and autumn. However, different profiles were observed in these two seasons. High bound contents were found at early photoand scotophase with lower values at late dark phase in spring, whereas higher contents were detected at this time in autumn. The present results indicate the existence of seasonally changing daily fluctuations in thyroid activity in Rana pereli and it seems that an interaction between photoperiod and temperature plays a role in the regulation of these daily changes.

The past decade has occasioned a dramatic increase in research on relationships between school size and a variety of outcomes, including measured achievement, high school completion rates, and postsecondary enrollment rates. An interesting interaction effect which has been found in replications across seven very different states is that as school size increases, the "achievement test score costs" associated with the proportion of economically disadvantaged students enrolled in a school also increase. In short, as schools get larger, average achievement among schools enrolling larger proportions of low socioeconomic-status students suffers. A traditional argument against smaller schools, however, is that they are simply


A prime concern in cultivating crops has always been water availability. The earliest crops may have been seeded about 18,000 years ago on the high dunes area of the Nile floodplain immediately after the flood waters receded (Wendorf et al. 1982). This practice assured adequate moisture for plants to grow and produce grain. Plant water-use efficiency was a topic for early scientific study (Briggs and Shantz 1913, Lawes 1850, Woodward 1699). Knowledge of the factors influencing crop water-use efficiency and a hope to improve the efficiency has continued to be an objective in many modern investigations. Wittwer (1975) identified water as the second-most limiting factor, behind land area, to increasing food production. He argued that a high research priority should be an improvement in the efficiency of water use by plants. Considerable research has been done on crop water-use efficiency during the past century, but much work resulted in empirical conclusions that seemed confusing or contradictory. However, recent developments in the understanding of the physical and physiological processes regulating crop growth and water loss allow crop water-use efficiency to be analyzed in quantitative, mechanistic terms.


1 The response of adrenal blood flow to adrenocorticotropic hormone (ACTH) was measured with radioactive microspheres in anaesthetized, dexamethasone‐treated, mongrel dogs. 2 Adrenocorticotropic hormone (2 u/h i.v.) increased adrenal blood flow within 15 min and this persisted for the duration of the infusion. 3 Cortisol concentrations also rose with ACTH infusion. 4 Indomethacin (6 mg/kg i.v. followed by 1 mg/min) did not affect the adrenal response to ACTH although plasma concentrations of indomethacin (21.9 ± 2.5 μg/ml) adequate to suppress prostaglandin synthesis were achieved. 5 We conclude that prostaglandins are not required for steroidogenesis or the adrenal haemodynamic response to ACTH.


Background: Burst fractures of the L5 vertebral body are uncommon. Treatment options described include prolonged immobilization and surgical stabilization, most commonly with an instrumented fusion from L4 to the sacrum. Methods: We describe the use of a minimally incisional technique to provide temporary internal fixation in a patient with an L5 burst fracture who was not a candidate for prolonged immobilization. Results: This technique resulted in an excellent outcome without the requirement for a fusion. Conclusion: Minimally incisional fixation procedures are a treatment option for select patients with L5 burst fractures.

21 Influenza A virus (IAV) and Streptococcus pneumoniae (S. pn.) are major causes of 22 respiratory tract infections, particularly during co-infection. The synergism between these 23 two pathogens is characterized by a complex network of dysregulated immune 24 responses, some of which last until recovery post IAV infection. Despite the high 25 serotype-diversity of S. pn. and the serotype-replacement observed since the 26 introduction of conjugate vaccines, little is known about pneumococcal strain-27 dependency in the enhanced susceptibility to severe secondary S. pn. infection following 28 IAV infection. Thus we studied how pre-infection with IAV alters host susceptibility to 29 different S. pn. strains with varying degrees of invasiveness using a highly invasive 30 serotype 4, an invasive serotype 7F and a carrier serotype 19F strain. A murine model of 31 pneumococcal co-infection during the acute phase of IAV infection showed a 32 significantly increased degree of pneumonia and mortality for all tested pneumococcal 33 strains at otherwise sublethal doses. The incidence and kinetics of systemic 34 dissemination however remained bacterial strain-dependent. Furthermore we observed 35 strain-specific alterations in the pulmonary levels of alveolar macrophages, neutrophils 36 and inflammatory mediators ultimately affecting immunopathology. During the recovery 37 phase following IAV infection, bacterial growth in the lungs and systemic dissemination 38 were enhanced in a strain-dependent manner. Altogether, this study shows that acute 39 IAV infection predisposes the host to lethal S. pn. infection irrespective of the 40 pneumococcal serotype, while the long lasting synergism between IAV and S. pn. is 41 bacterial strain-dependent. These results hold implications for developing tailored 42 therapeutic treatment regimens for dual infections during future IAV outbreaks. 43

IEEE 802.11 MAC protocol standard, DCF(CSMA/CA), is originally designed to ensure the fair channel access between mobile nodes sharing the local wireless channel. It has been, however, revealed that some misbehavior nodes transmit more data than other nodes through artificial means in hot spot area spreaded rapidly. The misbehavior nodes may modify the internal process of their MAC protocol or interrupt the MAC procedure of normal nodes to achieve more data transmission. This problem has been referred to as a selfish node problem and almost literatures has proposed methods of analyzing the MAC procedures of all mobile nodes to detect the selfish nodes. However, these kinds of protocol analysis methods is not effective at detecting all kinds of selfish nodes enough. This paper address this problem of detecting selfish node using Tsallis-Entropy which is a kind of statistical method. Tsallis-Entropy is a criteria which can show how much is the density or deviation of a probability distribution. The proposed algorithm which operates at a AP node of wireless LAN extracts the probability distribution of data interval time for each node, then compares the one with a threshold value to detect the selfish nodes. To evaluate the performance of proposed algorithm, simulation experiments are performed in various wireless LAN environments (congestion level, how selfish node behaviors, threshold level) using ns2. The simulation results show that the proposed algorithm achieves higher successful detection rate.


Because of pressures of new ventures, Ray King has had to resign as Chairman of the Wave Propagation Standards Committee (WPSC). Ray stepped down at the June '89 San Jose meeting, and turned the gavel over to me, Bud Flood.


In this paper, we propose an optimal power allocation scheme for joint pilot placement and space frequency (SF) code design for multiple input multiple output orthogonal frequency division multiplexing (MIMO-OFDM) wireless channels. OFDM is combined with multiple antennas to increase data diversity gain on a time varying multipath fading channel, resulting in a MIMO-OFDM system. A set of fast time-varying and frequency-selective fading channels is considered. The proposed pilot assisted transmission scheme multiplexes known symbols with information bearing data to estimate the channel in the presence of inter symbol interference (ISI). The channel is assumed to be unchanged for the duration of one OFDM block and change independently from one OFDM block to the other. The number of pilot symbols for each OFDM block is held constant and the symbols are dispersed throughout the block for efficient channel estimation. However, equally distributing the total power between the data and pilots doesn't optimize the transmission over a frequency-selective fading channel. We propose an optimal power allocation scheme for the joint pilot placement and space frequency code design scheme based on the channel response and the bit error rate (BER) values. This leads to substantial improvement in performance for a 2 times 2 MIMO-OFDM system. The results can be extended to MIMO-OFDM systems with any number of transmit and receive antennas.


This report is the second series of 157nm alternating phase shifting mask done at ISMT. In this report, we present a comprehensive study of balancing aerial image through various feature sizes and pitches. New resutls of resist imagse are analyzed from a 157-nm alternating PSM with a 0.85 NA lens. The mask is made by dual trench technique with a phase-etch of 115nm and an isotropic under-etch of 90nm based on optimized simulation results. With this dual trenched mask, the wafer printing images show tremendous improvement on 'line paring' phenomena. We also investigate some abnormal CD variation across line array observed during this study. The results from this work give an initial assessment of 157-nm capability of alternating PSM and 157-nm resist imaging quality.


This paper reports the mechanical response of semi-hexagonal part with three different multi-layer reinforcements. Unidirectional, plain woven and orthogonal fabric under quasi-static axial compression were considered. Meso-scale finite element numerical models with failure criterion were also established to simulate the onset and development of internal damage during the compression process. There were two different crush-failure modes occurring in the crush tests of the three different composite samples: a splaying mode for samples with unidirectional fabric, a buckling mode for samples with 3D orthogonal woven fabric and a mixture mode of both buckling and splaying for samples with the plain woven fabric. The samples reinforced by unidirectional fiber have the highest specific energy absorption and lowest peak loading, whereas the samples by 3D orthogonal fabric present the lowest specific energy absorption and highest peak loading. It was also demonstrated by a numerical model that the existence of Z-binder suppresses the delamination by restraining the expanding of warp and weft yarns. The comparison of numerical results and experimental data indicates that the structure of reinforcement has a significant role in the mechanical performance of textile composite.


In labs across Europe physicists are pushing the boundaries of how far we can cool the electrons in nano-fabricated circuits and quantum-enhanced devices. The cryogen-free revolution in dilution refrigeration has liberated researchers from a reliance on helium, a costly and non-renewable resource, and hugely expanded the numbers of cooling machines available for new science and quantum technology applications which exploit the properties of materials at kelvin and millikelvin temperatures.


Study Design. A retrospective database review. Objective. The purpose of this study was to analyze the rate of nonunion in patients treated with structural allograft and intervertebral cages in anterior cervical discectomy and fusion (ACDF). Summary of Background Data. Existing literature consists primarily of single-center studies with inconsistent findings. Methods. We performed a retrospective analysis of 6130 patients registered in the PearlDiver national database through Humana Insurance from 2007 to 2016. All ACDF patients with anterior plating who were active in the database for at least 1 year were included in the study. Patients with a fracture history within 1 year of intervention, past arthrodesis of hand, foot, or ankle, or a planned posterior approach were excluded from the study. Patients were stratified by number of levels treated, tobacco use, and diabetic condition. Nonunion rates of structural allograft and intervertebral cage groups after 1 year were compared using Chi-squared analyses. Results. Four thousand sixty-three patients were included in the allograft group, while 2067 were included in the cage group. Overall nonunion rates were significantly higher in the cage group (5.32%) than in allograft group (1.97%) (P < 0.01). When controlling for confounders, increased rates of nonunion were consistently observed in the cage group, achieving statistical significance in 25 of the 26 analyses. Conclusion. The increased rate of nonunion associated with intervertebral cages may suggest the superiority of allograft over cages in ACDF. Level of Evidence: 3


In this study, a series of novel D–π–A porphyrin sensitizers with different alkyl chains were designed and synthesized for dye-sensitized solar cells. The effects of different alkyl chains (methyl, methoxyl and hexyloxy groups) on the photophysical, electrochemical and photovoltaic performance were investigated systematically. The results indicate that the molar extinction coefficients of three dyes normally increase as the alkyl chain length increases. Furthermore, it is also found that the incident photo-to-current conversion efficiencies (IPCEs), short circuit current (Jsc) and open circuit voltage (Voc) of the dye-sensitized solar cells (DSSCs) based on WH-C1, YD20 and WH-C2 increase with the elongation of alkyl chains in the order of WH-C1 < YD20 < WH-C2. Accordingly, under standard global air mass 1.5 solar conditions, the optimized WH-C2-sensitized cell could produce a high conversion efficiency (η) of 7.77%, with a Jsc of 13.10 mA cm−2, a Voc of 831.10 mV, and a fill factor (FF) of 0.70.


This article narrates the process whereby my work as a qualitative researcher has undergone some profound vicissitudes—from a study of life stories, to a popular book, and then to a play, each construction adding insight and meaning to the topic, and empowerment to the participants. The reflexive writing about these airs issues which normally remain undisclosed in academic reports. The study dealt with autobiographical narratives ofwomen in the New Family. The book represented these storied lives with the necessary alterations. The play brought the characters back to life, albeit a different life than the "real" one. The narrative of these transformations is presented in the context of the " performance turn in the social sciences" on one hand, and the ethical concerns for the research participants and their life stories on the other hand.


This article reviews the causal exclusion argument and confronts it with some recently proposed refutations based on the interventionist account of causation. I first show that there are several technical and interpretative difficulties in applying the interventionist account to the exclusion issue. Different ways of accommodating the two to one another are considered and all are shown to leave the issue without a fully satisfactory resolution. Lastly, I argue that, on the most consistent construal, the interventionist approach can provide grounds for thinking that higher-level causal notions are as legitimate as lower-level causal notions, but it does not provide grounds for postulating inter-level causal interactions.


The exploration of safe and efficient polycationic gene vectors from natural small molecules such as kanamycin was proposed. Cationic hyperbranched glycoconjugated polymer was synthesized by the Michael-addition polymerization of kanamycin and N,N′-methylenebisacrylamide, and the resultant product was well characterized by FTIR, 1H NMR, 13C NMR, SEC-MALLS and ζ-potential analyses. The nitrogen content (7.3%) of this kanamycin-based hyperbranched glycoconjugated polymer was much lower than that (32.6%) of polyethylenimine (PEI) control. Moreover, this resultant polymer could be degraded in acidic conditions. Therefore, the hyperbranched glycoconjugated polymer showed low cytotoxicity, even lower than that of natural biomacromolecule chitosan. Due to the existence of various primary, secondary and tertiary amines in the polymer backbone, hyperbranched glycoconjugated polymer exhibited high buffering capacity and strong pDNA condensation ability. In vitro transfection showed that the luciferase expression of hyperbranched glycoconjugated polymer was about 4.4 × 108 RLU per mg protein, approximately 33-fold greater than that of chitosan transfection. These results demonstrate that the construction of highly branched polycations from natural small molecules provides a new opportunity for developing safe and efficient gene vectors.


Ni/Si multilayer contact structures to 4H-SiC after subsequent annealing steps are investigated with electron microscopy methods. After high temperature annealing step, specific defects in the contact structures are observed. The influence of phase transformations during annealings on the morphology on the contacts is discussed and the explanation of formation mechanism of voids within contact layer is proposed.


The growth was studied in Pacific white leg shrimp Litopenaeus vannamei reared in an indoor tanks for 20,40,60,and 80 days and water quality and nitrogen and phosphorus budgets were monitored in the culture tanks at different culture time.The results showed that the main water quality indexes including pH,DO,TAN,NH3-N,NO-2-N,and CODMn were effectively controlled within safe range at different culture period.The regression equations of body weight(W)-length(L) relationship of the shrimp was expressed as W=aLb(a: 0.0126 to 0.0135,b: 2.7919 to 2.8873),and the linear correlation between body length and culture time was described as L=at+b(a: 0.0673 to 0.0818,b: 1.7310 to 2.1536),with the linear relationship between body weight and culture time of W=at+b(a: 0.0187 to 0.0496,b:-0.3390 to 0.0535).The relationship between survival and culture time was expressed as a logarithmic equation of S=-11.807 ln t+100.66.The diets were found to be the main factor affecting the nitrogen and phosphorus inputs,followed by initial water quality and the shrimp size in each pond at different culture time.The output nitrogen and phosphorus derived from the shrimp were found to be dropped over the culture procedure.


The aetiology of sporadic colorectal cancer (CRC) is complex and involves genetic and lifestyle factors. To deal with the daily load of carcinogens, present in food, tobacco smoke etc., humans possess an efficient system of defence against such compounds and an important role is reserved for the detoxification enzymes UDP-glucuronosyltransferases (UGTs) and NAD(P)H:quinone oxidoreductase (NQO1). However, when the detoxification capacity of the colon is insufficient, this may lead to DNA mutations and damage of cells and ultimately to development of CRC. Here, we described that addition of dietary compounds to the diet of rats induced UGT enzyme activity in liver (flavone: 10.6x, coumarin: 6.2x, alpha-angelicalactone: 4.2x, D-limonene 3.2x) and colon (curcumin: 3.1x, coumarin: 2.7x, quercetin and alpha-angelicalactone: both 2.2x). Furthermore, it seems worthwhile to study the combined effect of dietary compounds, since additional or synergistic effects may occur. This could be concluded from a study in which a combination of flavone and alpha-angelicalactone was supplemented to the diet of rats. Enhanced enzyme activity might lead to more efficient detoxification of carcinogens and hence contribute to the prevention of CRC. However, the significance of results from animal studies should be verified in human intervention studies. Genetic polymorphisms in detoxification enzymes may result in less active enzymes, which may lead to reduced conversion of carcinogens in the colon and eventually an increased risk for CRC. Here, we reported that polymorphisms in the detoxification enzymes UGT1A6, UGT1A7 and NQO1 were found significantly more often in patients with CRC as compared to healthy controls, indicating that the presence of these variant genotypes may contribute to development of CRC. Finally, we showed by measuring oxygen radical production in whole blood from patients with a history or at risk for CRC and age- and gender-matched controls, that oxidative stress might be involved in the aetiology of sporadic CRC


A simple, rapid and sensitive UV spectrophotometric method was developed for the simultaneous estimati on of Enalapril maleate (ENM) and Hydrochlorothiazide (HC TZ) in pharmaceutical dosage forms. This method emp loys solving of simultaneous equations based on the meas ur ment of absorbance at the λ max values of ENM (207nm) and HCTZ (272nm).Calibration curves were linear in the range of 5-50μg/mL and 5-30μg/mL for ENM and HCTZ respectively. Recovery studies for ENM and HCTZ wer e p rformed and the percentage recovery for both th e drugs was obtained in the range of 98.4-99.1 % and 98.8-9 9.1 % respectively. The method showed good reprodu cibility and recovery with % RSD less than 2. The proposed m thod can be successfully applied for the determina tio of ENM and HCTZ in pharmaceutical formulations and is validated according to ICH guidelines.


"Diffusion‐weighted" MRI in the normal human brain and in a patient with a cerebral metastasis is demonstrated. The method employed was a modified CE‐FAST sequence with imaging times of only 6‐10 s using a conventional 1.5‐T whole‐body MRI system (Siemens Magnetom). As with previous phantom and animal studies, the use of strong gradients together with macroscopic motions in vivo causes unavoidable artifacts in diffusion‐weighted images of the human brain. While these artifacts are shown to be considerably reduced by averaging of 8‐16 images, the resulting diffusion contrast is compromised by unknown signal losses due to motion. © 1989 Academic press, Inc.


Photon echo measurements made at 2 °K on the 3H4 - 1D2 transition in Pr3+:LaF3 show that magnetic dipolar couplings between the Pr and F nuclei account for the 56 kHz homogeneous linewidth of this transition.1 The homogeneous broadening arises from the enhanced 141Pr nuclear moment (I=5/2) interacting with the local field fluctuations of the 19F nuclear moments undergoing mutual spin flip transitions. Such resonant fluctuations should, in the absence of a fluorine spin diffusion barrier, produce a homogeneous linewidth of about 200 kHz which is, in fact, roughly what is observed for the inhomogeneous broadening of the Pr3+ hyperfine levels and is considerably broader than that obtained by the photon echo measurements. Shelby et al2 proposed a simple model analogous to the spin diffusion barriers responsible for narrowing the homogeneous lines in certain electron paramagnetic resonance transitions3. In such systems, the field produced by the electron magnetic dipole moment (2-3 orders of magnitude larger than the enhanced nuclear moment associated with the ground state of Pr3+ in LaF3) de-tunes the nearest neighbors from each other, prohibiting mutual spin flips among them. Thus, the fields produced by the neighboring spins are static and their interaction with the paramagnetic ion contributes to the inhomogeneous linewidth and not to homogeneous broadening. The de-tuned neighbors are referred to as the "frozen core." Application of this picture to the case of Pr3+:LaF3 is supported by the calculation of Devoe et al.4 Their Monte Carlo calculation of the Pr3+ optical dephasing times shows that the observed homogeneous linewidth could be explained by deleting the nearest neighbor F spins from the lattice of rapidly fluctuating fluorine moments, in effect, treating them as part of a frozen core.


Dams and reservoirs greatly influence flow and sediment discharge regimes of rivers and can have significant impact on downstream reaches water quality. Bed load sediment management in reservoirs is required to save the reservoir capacity. In the paper a method for estimation of sediment accumulation/and removal is presented. The method allows determining future trends of the reservoir sedimentation.


This paper explores the usefulness of various aspects of recent feminist
thought on the 'maternal subject' for thinking about the ethical relation to
future generations. Much ethical literature on future generations is characterized
by an assumption that future generations are separate and distant
from the 'present' generation who make ethical decisions. I put forward
the idea of the 'social maternal' to challenge this assumption, and suggest

Statistical tests in the ANOVA and correlation families (e.g., t-test, Pearson's correlation, multiple regression, path analysis) require the distribution underlying the dependent variables to be normally distributed. Because the normal curve is defined by two parameters (the mean and standard deviation), such tests are referred to parametric. Another class of tests is called nonparametric, or more properly, distribution-free, because they do not make any assumptions about the parameters of the population from which the sample(s) are drawn. However, while they are distribution-free, they are not assumption-free. Many of the nonparametric tests have the same assumptions as parametric ones, such as that the observations are independent; that they are at a certain level of measurement (e.g., nominal or ordinal); and with some, that the distributions are similar across groups (i.e., if they are skewed, then they are skewed in the same direction for all groups).

Abstract : A field-scale investigation of pump-and-treat remediation was conducted at Dover AFB, DE, in sheet-pile test cells isolating two adjacent segments of a long-extant groundwater plume. For a given volume of extracted water, the fractional removal of contaminant mass was higher for the pulse pumped cell (PPC) than the continuously pumped cell (CPC) for all contaminants whose maximum aquifer concentrations were at or very near the aquiferlaquitard interface. Overall, the results of this work indicate that contaminant transport and subsurface remediation are influenced not only by (I) spatial variability of the transport medium (aquifer), but also by (2) spatial variability in the pre-remediation contaminant distribution, and (3) spatial variability of the sorption properties of the impacted low permeability media (aquitards, clay lenses, etc.). The results of this work have been and will continue to be extrapolated from Dover-specific conditions to a variety of hydrogeologic situations via modeling to emphasize the effects ofaquitard and initial" contamination heterogeneity on long-term remediation by any method constrained by diffusion of contaminants from low permeability media.

Meanwhile, the theory of information mining is used to forecasting load of boilers. Obtain remarkable benefit of energy saving 9%, and to achieve the boiler load guidance, the error of 1%.


A novel asymmetric U-Shaped slot antenna with WLAN application is proposed and fabricated. The proposed antenna consists of an asymmetric U-shaped slot and an inverted L-shaped slot which are designed to applied to WLAN devices, in addition, fed by a coplanar waveguide (CPW) Furthermore, Good agreement is achieved between the measurement and simulation, which indicates that a 10-dB bandwidth of 21.8% from 2.25 to 2.8 GHz which completely cover the WALN (2.4 – 2.48 GHz) band is covered in the designed antenna. Meanwhile, compared to other recent works, a single layer structure, and a more compact size are the key features of the proposed antenna. Keywords-WLAN; slot antenna; coplanar waveguide (CPW)


We propose an auto-adaptive segmentation approach (non-linear) based on a description of satellite images using an adjacency graph. The represented space is modeled using the Voronoi diagrams and their dual graph (Delaunay triangulation). The morphological transformations of opening and closing are applied to obtain suitable and significant regions conserving the principal features of the most important landscape units. The results of this approach have been tested using a SPOT5 image of Toulouse, France.


Summary. We report a case of Sezary syndrome with two abnormal CD4+ T‐cell populations detected in the peripheral blood by flow cytometry immunophenotyping and DNA cell content, suggesting a biclonal T‐cell lymphoproliferative disorder. Despite these findings, molecular analysis of the T‐cell receptor genes was consistent with a monoclonal T‐cell proliferation, supporting the existence of intraclonal diversity rather than a true biclonal disease. The patient achieved a transient response with 2‐deoxycoformycin, with a selective decrease of the larger/hyperploid T‐cell population; later on, an increased representation of this T‐cell population was observed concomitantly with clinical relapse.


How do citizens hold their leader accountable during an ongoing war? The authors distinguish between two models of accountability—the "decision maker" and "managerial" models—and investigate their implications in the context of the current war in Iraq. They employ a novel measurement model and a database of survey marginals to estimate weekly time series of aggregate beliefs about various aspects of the war. Consistent with the "decision maker" model, they find that shifts in aggregate support for the war have a greater impact on presidential approval than do equivalent shifts in perceptions of war success or approval of the president's handling of the war. Conversely, aggregate perceptions of success are more responsive to casualties and key events than are aggregate beliefs about the war's merits. This suggests that the link from casualties and events to presidential approval is less direct than previously assumed.


Manganese oxides have been recently investigated as excellent catalysts for peroxymonosulfate (PMS) activation and the reported mechanisms are mostly forming reactive oxygen species (ROSs). This study investigated the use of an iron-doped manganese oxide, synthesized via air oxidation under strong alkaline conditions. The oxidation of three substrates was affected by their adsorption at the catalyst surface, solution pH and co-solutes. Common ROS scavengers inhibited the oxidation of bisphenol A (BPA), suggesting the possible involvement of ROSs; however, the PMS decomposition tests with and without BPA and the comparison with a 1O2-generation system ruled out the formation of ROSs, and pointed to direct electron transfer between the adsorbed BPA and complexed PMS as the mechanism. To prove this mechanism, the catalyst was coated to graphite sheets and a Galvanic Oxidation Process (GOP) was developed to separate BPA and PMS into two half-cells. Upon PMS addition into one cell, BPA was quickly oxidized in the other cell, confirming the occurrence of electron transfer. The GOP system successfully degraded BPA in both surface water and hypersaline shale gas produced water. Overall, this study developed a new catalyst for PMS activation and unveiled the advantages and potential applications of electron shuttling catalysts.


the internet of things (IoT) is consisting of many complementary elements which have their own specificities and capacities. These elements are gaining new application and use cases in our lives. Nevertheless, they open a negative horizon of security and privacy issues which must be treated delicately before the deployment of any IoT. Recently, different works emerged dealing with the same branch of issues, like the work of Yuwen Chen et al. that is called LightPriAuth. LightPriAuth has several drawbacks and weakness against various popular attacks such as Insider attack and stolen smart card. Our objective in this paper is to propose a novel solution which is "authentication scheme with three factor using ECC and fuzzy extractor" to ensure security and privacy. The obtained results had proven the superiority of our scheme's performances compared to that of LightPriAuth which, additionally, had defeated the weaknesses left by LightPriAuth.


The excretion of radioactivity in the urine and feces of female rhesus monkeys after administration of C-carbon-14 labeled progesterone was studied to measure the conversion rate of progesterone to androsterone. During the first 7-9 days 37% of the radioactivity appeared in the urine and 49% in the feces. The rate of excretion was greatest the first 24 hours after injection. Fecal radioactivity was greatest after the first 24 hour period while urinary radioactivity was greatest the first 24 hours. Androsterone has the same inportance in these animals as a urinary catabolite of progesterone as pregnanediol does in man.


A method for controlled growth of silicon carbide and structures produced by the method are disclosed. A crystal of silicon carbide (SiC) can be grown by placing a sacrificial substrate in a growth zone with a source material. The source material may include a low-solubility impurity. SiC is then grown on the sacrificial substrate to condition the source material. The sacrificial substrate is then replaced with the final substrate, and SiC is grown on the final substrate. A single crystal of silicon carbide is produced, wherein the crystal of silicon carbide has substantially few micropipe defects. Such a crystal may also include a substantially uniform concentration of the low-solubility impurity, and may be used to make wafers and/or SiC die.


The unrelenting technological advancement in the generation of wireless networks in recent years has awakened the motion concerning the inclusion of satellites in personal communications. Leveraging their ability to provide wide coverage, uniform services, wide bandwidth, and so forth, Satellite systems will be expected to co-exist with the current state-of-the-art infrastructure of terrestrial networks. Herein, we present a comparative study on the representative digital modulation techniques for use in personal satellite communications. We discuss the advantages and limitations of different modulation techniques, such as phase shift keying, continuous phase modulation, amplitude phase shift keying, and quadrature amplitude modulation. We also perform evaluations based on spectral efficiency, power efficiency, modulation error ratio, error vector magnitude, and peak-to-average power ratio in the presence of high power amplifier nonlinearities and Doppler effects. Comparisons in the form of tables, illustrations, and curves are also presented. In correspondence to the comparisons made basing on the aforementioned metrics, we conclude that continuous phase modulation is the best candidate modulation scheme for personal satellite communications since it outperforms other schemes by compromising the trade-off between power efficiency, bandwidth efficiency, and immunity to errors. We further present open issues that would reinforce personal satellite communications in terms of reliability, throughput and latency, other than power and spectral efficiency, if combined with appropriate modulation schemes.


Abstract Quasi-biennial global, midlatitude, and tropical oscillations were observed using top-of-the-atmosphere outgoing longwave radiation (OLR), surface air temperature (SAT), and cloud amount for the period from 1979 to 1989. The in-phase quasi-biennial variations of OLR and SAT were strongest in the Tropics. Two prominent peaks in these two data fields were observed after the end of the main phases of the 1982–83 and 1986–87 El Nino-Southern Oscillation (ENSO) events, which were also accompanied by a decrease in the mean tropical cloud cover. The quasi-biennial signal was less noticeable in the midlatitudes during the two ENSO events but was strong during two non-ENSO peaks occurring in 1980–81 and 1989–90. In this study, the authors used two SAT datasets comprised of departures estimated from a specific base period, where the record of these two datasets predates the start of this century. The OLR dataset was obtained by concatenating Nimbus-7 (1979–87) and Earth Radiation Budget Satellite (ERBS) (1...

Past attempts to generalize the Stolper-Samuelson theorem have used a matrix of real income terms which are sufficient but not necessary to define a change in utility. One can define a second matrix of terms which are necessary and sufficient for a change in indirect utility. Using this matrix, the paper extends the Stolper-Samuelson theorem to a model of any dimensions and to households which have diversified ownership of factors. The theorem states that there is a positive and a negative element in every row and every column of the matrix showing household responses to changes in goods prices.

A number of recent studies have suggested that for small businesses to maximise the benefits and minimise difficulties when adopting electronic commerce, they should be involved in some form of strategic alliance (network) with other small firms. This study compares the benefits gained and the difficulties encountered by SMEs that were part of a strategic alliance and those that were not. The results show that while difficulties are minimised by involvement in a strategic alliance, there are no significant differences in the benefits gained.


Background. This paper reports on the attitudes towards dementia and self-rated competence of staff working in residential care homes for the elderly (RCHE) in Hong Kong. Methods. This cross-sectional survey involved 1780 RCHE staff. Staff attitudes were assessed using the Chinese version of the Approach to Dementia Questionnaire, whereas self-rated competence in relation to dementia care was assessed using a specially developed questionnaire. Results. Of the respondents, 64.9% (n=1155) were working in subvented RCHE and 92.1% (n=1640) were females. In terms of education levels of staff, 18.0% (n=320) were professional, 70.3% (n=1252) were semiskilled, 2.5% (n=45) were non-trained, and 9.2% (n=163) were missing data. Respondents from private RCHE had significantly lower education levels (p 45 hours per week). Staff training to improve knowledge and attitudes, and provision of enabling work condition for staff to adopt a more person-centred approach in dementia care are recommended.


All the data for this article have been collected and organized during the specialization course in Rural Family Agriculture and Education offered by 19 Universities in Brazil. In this course, the student Edvânia de Souza Silva wrote, under my supervision, the thesis 'Formation for the Transition of Conventional Agriculture to Agroecology Agriculture: The case of the diffusing family of Pajeú Mirim-Tabira/PE. Our research environment is the community of Pajeú Mirim, located 18 km away from its main city of Tabira. From the gathered data and debates developed there, we produced this article in order to raise thoughts about the speeches and practices built through our research process. Our main proposal is to contribute to the formation of a new professional in the family agriculture scenario in the countryside of the Pernambuco State. Thus, we gave priority to the learning experience of techniques, methodologies, and acquaintance among the 'true authors' of this history the agriculturists in a way to develop actions together, therefore contributing to the formation and understanding of the current transition from a conventional agriculture to a process based on agroecology. To achieve that, we focused on the use of different alternatives to help in the production system recovery, managing plagues, and diseases with natural defenses, rational use of water through an irrigation system by micron-aspersion and dripping. Our main research question relates to the agriculture scenario in the countryside that involves less diversification and lack of hydric infrastructure. In areas for agricultural production, families who own lands nearby the dam of 'Brotas' and the Pajeú river, plant fruits and vegetables using agrochemicals. In such manner, the debate on economic and environmental sustainability raises questions about changing the current planting culture to an agrochemicalfree environment. Our methodology was based on the community needs and demands, considering the importance of theoretical approach for the farmers. Hence, the following activities were carried through:Mobilization within community reunions, for a better interaction between agriculturists and researchers so they could preview and understand their own problems and demands;Informal interviews with people from the community; Trainings related to the negative impact of agrochemicals usage;Trainings related to agroecological alternatives as a preparation for the natural defenses in the handling of plagues and diseases;Experience and knowledge exchange between agriculturists and researchers. Our research sample consisted of three families with a certain level of awareness, following these criteria: to have access to their own water in their properties, which is an important requirement for proper production. That was possible because the families are located near the Pajeú river.


In the course of property distribution and case execution of bankrupt industries and companies,should their managers' salary be payed in advance like the workers? Because there is no concrete regulation and theoretical explanation,it becomes a legislative proplem.To solve this problem,we should distinguish the workers' salary and the managers' salary debt based on the idea of workers' salary priority.

Purpose. to present new opportunities in the rehabilitation of children with congenital anophthalmos and microphthalmos with method of step-by-step prosthetics. Material and methods. the analysis of clinical material for 3 years (2015-2017) on the basis of ocular prosthetics office of Moscow Helmholtz Research Institute of Eye Diseases. The clinical group consisted of 155 children: with congenital anophthalmos - 59 patients and microphthalmos - 96 patients (bilateral microphthalmos (9), bilateral anophthalmos (5)). The age of patients ranged from 1 month to 11 years. Under the age of 1 year, there were 82 children (53%). The identified dynamics in the age category of children significantly increased the number of patients under the age of 1 year who were treated for primary ocular prosthetics (53% for 2015-2017. versus 20.2% for 2000, 2013). Results. all 155 patients were treated for dilatation of the conjunctival cavity by the method of step-by-step eye prosthetics. To step eye prosthesis used set increasing in size retail, which can be varied in 3-4 weeks as stretching of soft tissues. In congenital anophthalmos to achieve stable results were performed from three to 6-7 replacement of the eye prosthesis, in congenital microphthalmos, depending on the size of the eye 4-6 replacement of the eye prosthesis. The volume of eye prosthesis used for 3 years increased by 4-5 times, respectively, noted an increase in the size of the conjunctival cavity, eyelids and the size of the orbit. Conclusion. The possibility of frequent and timely replacement of the medical eye prosthesis ensures the gradual formation of an adequate conjunctival cavity, and, accordingly, the development of bone orbit and eyelids. This treatment tactics promotes both functional and cosmetic rehabilitation of patients of early childhood with congenital anophthalmos and microphthalmos.


Abstract A multi-objective discounted Markov decision process (MDP) with expectation and variance criteria is discussed. First, difficulties in variance minimization are discussed and it is shown that variance minimization is much more difficult than the expectation optimization. Then, the multi-objective MDP with expectation and variance criteria is formulated as a multi-objective non-linear programming problem. An algorithm for finding a stationary satisfactory Pareto policy is proposed by applying the satisficing trade-off method of Nakayama. In the proposed algorithm, a decision-maker need not have a high degree of judgment and it is easy to take the balance of expectation and variance criteria and furthermore, the number of auxiliary optimization problems to be solved is quite small. Numerical examples show the efficiency of the proposed algorithm.


At present fruit beverages are generally synthetic flavored, bottled and sold in the market. If this could be substituted with fruit pulp and milk, it will be more beneficial to the consumer, dairy industries and beverage manufacturers and fruit growers. The development of nutritionally value added product could therapeutically help on improving the health of consumers. Mango pulp and milk can be utilized to make the product therapeutic, prophylactic and nutritionally rich which may increase its demand in food and beverage industry. Mango (Mangifera indica L.) is one of the favored fruits in the tropical and sub-tropical regions. It has an excellent flavor, attractive fragrance, delicious taste and high nutritional value that have made it one of the best fruits. The researchers reported preparation of fruit flavored beverages using whey obtained from coagulation of cow milk, Gajarani et al., (1986).


Particulate matter with a diameter of less than 2.5 microns (PM2.5) in the air is one of the most critical pollutants related to air quality. Exposure to high levels of PM2.5, which can be inhaled and carry harmful chemicals deep into the lungs and bloodstream, can have acute or chronic adverse health effects. A reliable, convenient and low-cost method to obtain PM2.5 concentration can help people improve their awareness of it. At the same time, it can also provide a certain reference for the prevention and control of haze, for air purification and for some other work to reduce the harm of air pollution to human health. In this paper, from the perspective of deep learning, with the help of photos that can be taken anywhere, we combined convolution neural network and support vector regression machine to estimate PM2.5. The method used in this paper is compared with other methods using the same dataset to prove its effectiveness.


Pulses are grown in about 3.35 million hectare area in Rajasthan, which is about 16% of the total cropped area of the state. Mung bean and moth bean are the main rainfed crops of arid zone. The average productivity of these crops is very low (250-300 kg ha-I). Despite many factors, low adoption of improved technologies is one of the important reasons for low production. Lot of technologies have been developed by research institutes and agricultural universities, but few of them have been adopted by the farmers. There may be gap between the technologies developed at Research Station and technologies adopted by the farmers. Keeping this in view the present study was under taken to find out the adoption gap in mung bean and moth bean production technology.


A generalization of step‐up and step‐down multiple test procedures is proposed. This step‐up‐down procedure is useful when the objective is to reject a specified minimum number, q, out of a family of k hypotheses. If this basic objective is met at the first step, then it proceeds in a step‐down manner to see if more than q hypotheses can be rejected. Otherwise it proceeds in a step‐up manner to see if some number less than q hypotheses can be rejected. The usual step‐down procedure is the special case where q = 1, and the usual step‐up procedure is the special case where q = k. Analytical and numerical comparisons between the powers of the step‐up‐down procedures with different choices of q are made to see how these powers depend on the actual number of false hypotheses. Examples of application include comparing the efficacy of a treatment to a control for multiple endpoints and testing the sensitivity of a clinical trial for comparing the efficacy of a new treatment with a set of standard treatments.


This paper proposes a genetic-based K-means (GK) algorithm for selection of the k value and selection of feature variables by minimizing an associated objective function. The algorithm combines the advantage of genetic algorithm (GA) and K-means to search the subspace thoroughly. Therefore, our algorithm converges globally. A weighting junction is then introduced to initialize the parameters of the algorithm. The experiments on a synthetic dataset and a real dataset shows that (i) GK outperforms K-means since GK achieves the minimal value of the objective junction and (ii) GK with the weighting function performs better than GK


Axonal loss occurs in many neurologic disorders and its prevention is a major target of disease-modifying therapies. Over the past several years, studies in the Wlds mutant mouse model characterized by delayed Wallerian degeneration (WD) following axonal transection have provided important insights into the mechanisms of axon death.1-3 Wlds mutant mouse axons survive 10-fold longer than in wild-type mice following axotomy. Studies show that WD occurs via a canonical pathway that results in a reduced availability of nicotinamide adenine dinucleotide (NAD+) and thus directly affects energy metabolism.4-6 Accordingly, there is increasing evidence that mitochondria have a critical role as initiators of the axonal degeneration program.7,8 Axons are particularly vulnerable to mitochondrial damage given their high energy requirement.9 The basic pathways for axon injury are relevant not only following transection, but also in a wide range of axonal disorders, as supported by several preclinical disease models4-6 (Figure). The effects of mutations in genes regulating the axonal injury program in humans10-15 confirm that these basic mechanisms occur in a wide range of neurologic disorders. The elucidation of the central regulators of programmed axon death4,5,16-20 and the identification of molecular biomarkers that signal the activation of this process21 provide potential therapeutic targets for axonal protection.22


We discuss the effects of spatial interference between two infectious hotspots as a function of the mobility of individuals (wind speed) between the two and their relative degree of infectivity. As long as the upstream hotspot is less contagious than the downstream one, increasing the wind speed leads to a monotonic decrease of the infection peak in the downstream hotspot. Once the upstream hotspot becomes about between twice and five times more infectious than the downstream one, an optimal wind speed emerges, whereby a local minimum peak intensity is attained in the downstream hotspot, along with a local maximum beyond which the beneficial effect of the wind is restored. Since this nonmonotonic trend is reminiscent of the equation of state of nonideal fluids, we dub the above phenomena "epidemic condensation". When the relative infectivity of the upstream hotspot exceeds about a factor five, the beneficial effect of the wind above the optimal speed is completely lost: any wind speed above the optimal one leads to a higher infection peak. It is also found that spatial correlation between the two hotspots decay much more slowly than their inverse distance. It is hoped that the above findings may offer a qualitative clue for optimal confinement policies between different cities and urban agglomerates.

Objectives We studied the different risk factors to involvement lymph pelvic node and to recurrence in patients with early cervical cancer in our population. Methods We retrospectively analysed the data from 85 patients with early cervical cancer treated at the European Hospital George Pompidou in Paris between January 2004 and June 2018. Inclusion criteria: patients with cervical cancer stage IA1- IIA. Exclusion criteria: missing or insufficient follow-up data (< 6 months), not node stage evaluation and patients who received neoadjuvant radiochemotherapy. The chi-square test (or Fisher's test if sample size too small) was used to compare qualitative variables. A value of p=0.05 was used as the limit of statistical significance in the parametric analyses NS = no significance. Results Abstract 149 Table 1 Association between patients and tumor characteristics and pelvic nodes status. Abstract 149 Figure 1 Abstract 149 Table 2 Association between patients and tumor characteristics and recurrences Conclusions Many factors for recurrence have been described in patients with cervical cancer. Lymph node involvement is considered the main prognostic factor. Other prognostic factors for recurrence are tumour size, maximum stromal invasion, and presence or absence of lymphovascular space involvement (LVSI) have been evaluated. Different factors had been associated for risk to involvement lymph pelvic nodes: depth of invasion parametrial involvement, lymphatic-vascular space invasion, tumor grade and size of primary tumor. We don´t find any factors associated with the risk of involved nodes. The only factor associated with the risk of recurrence was tumor size.

Although having shown promising clinical outcomes, the effectiveness of 5‐aminolevulinic acid‐based photodynamic therapy (ALA‐PDT) for squamous cell carcinoma (SCC) and glioblastoma remains to be improved. The analgesic drug methadone is able to sensitize various tumors to chemotherapy. In this in vitro study, the influence of methadone to the effectiveness of ALA‐PDT for SCC (FADU) and glioblastoma (A172) was investigated on the protoporphyrin IX (PpIX) fluorescence, survival rates, apoptosis, and cell cycle phase, each with or without the presence of methadone. The production of PpIX was increased by methadone in FADU cells while it was decreased in A172 cells. The survival rates of both cell lines treated by ALA‐PDT were significantly reduced by the combination with methadone (P < .05). Methadone also significantly increased the percentage of apoptotic cells and improved the effect of ALA‐PDT on the cell cycle phase arrest in the G0/G1 phase (P < .05). This study demonstrates the potential of methadone to influence the cytotoxic effect of ALA‐PDT for both SCC and glioblastoma cell lines.


Abstract Applications of the shifted Legendre polynomial expansion to the analysis and identification of the non-linear system described by a Hammerstein model which consists of a single-valued non-linearity followed by a linear plant are studied. For the analysis, by using the shifted Legendre polynomial expansion, the solution of a non-linear state equation is reduced to the solution of a linear algebraic matrix equation. For the identification, through the shifted Legendre expansions of the measured input-output data, the unknown parameters of both the linear plant and the characterization of the non-linear element are estimated using the least-squares method. Algorithms are presented. Numerical examples are given to illustrate the use of this approach.

Abstract Polygynous mammals often have male-biased sexual size dimorphism due to male–male competition for mates. However, fecundity selection may enlarge female body size. The Mongolian gerbil Meriones unguiculatus (Milne-Edwards, 1867) is a social rodent of promiscuous mating. Male gerbils exhibit social dominance hierarchy, which may differentiate reproductive success among male gerbils with larger males having more reproductive opportunities. This study investigated the hypothesis that social dominance hierarchy would result in male-biased sexual size dimorphism in Mongolian gerbils. We also tested the prediction of fecundity selection, that litter size would be positively related to female body mass of Mongolian gerbils. Body mass, carcass weight and body length of male gerbils were greater than those of females. Therefore, male-biased sexual size dimorphism was supported in Mongolian gerbils. Although litter size of female gerbils increased with increasing carcass weight, ecological constraints (e.g. burrow living and increased energy expenditure during pregnancy) probably kept female body size smaller than male body size of the gerbil. Social interactions may mediate sexual and fecundity selections on the body size of social rodents.

Description: Wound management and reconstructive surgery are among the most challenging and innovative subspecialties of veterinary surgery. As treatment options for traumatic injuries and cancers have advanced, so too has the focus and importance grown of understanding wound healing, wound management and atraumatic surgical technique. Atlas of Small Animal Wound Management and Reconstructive Surgery, Third Edition is a valuable, one–stop reference for veterinary surgeons, residents, and small animal practitioners. This full–color reference presents essential information on basic principles of wound healing and wound management, common complications, and general surgical considerations. Also, new to this edition, the text presents a wider variety of topics including skin fold disorders, urogenital surgery, new flap techniques, and an expanded chapter on facial reconstruction. It also contains significant updates on wound healing physiology and equipment and dressing materials.


ABSTRACT AH-7921 is a synthetic opioid that was developed in the early 1970s. It has resulted in several fatal and nonfatal intoxications, despite not having approval from the US Food and Drug Administration. To date, AH-7921 is listed as a schedule I drug, and there have been no clinical trials exploring the safety of AH-7921. Herein, we provide an analysis of existing case reports available in the literature regarding AH-7921. We searched PubMed, Scopus, Web of Science, and EBSCO for articles (up until December 2017) using the terms "AH-7921" and "AH7921." In total, 48 articles were identified, and 5 articles were included in our review. A total of 14 cases were found, of which 13 resulted in fatalities. The oral route of administration was reported in two cases, and most cases reported use of concomitant pharmaceutical agents. Pulmonary edema was the most common finding postmortem among deceased cases, with nine of the cases having heavier lungs. Overall, fatalities occurred with low and high concentrations of AH-7921 in the femoral blood. We strongly encourage toxicology screenings for this novel opioid to be included when an overdose of an opioid of unknown nature is suggested.


A thermochromic magnetic ionic liquid containing a cationic iron(III) Schiff-base complex has been developed, whose color and magnetic moment change with temperature because of spin crossover in the liquid state. This spin-crossover behavior closely resembles that of a solid having the same cation.

This article analyzes part of the data collected in a doctoral research linked to the National University of Rosario, Argentina. The research focused on the place of Catholic schools in the contemporary educational scenario based on the perception of the various actors in education (managers, educators, pastoralists, and students). It intended to problematize the perceptions of High School students about their experience of schooling. One hundred fifty-seven students from six Catholic schools in Belo Horizonte/MG presented their perceptions of school life through a written questionnaire 2 E.D'A.F. GUIMARÃES & P. DABIN Revista de Educação PUC-Campinas, Campinas, 26: e215325, 2021 https://doi.org/10.24220/2318-0870v26e2021a5325 and a drawing. The data were analyzed using Qualitative Epistemology and its concept of subjective meanings. Based on their experience in the Catholic school, the students: evaluate how plastered educational system prevents the development of integral educational processes focused on human development; report the traditionalism that runs through schooling today; demonstrate difficulty in identifying the school's contribution to their formation and definition of life project; and attribute different meanings to the school education, according to their trajectory in the Catholic school.


2-Mercaptobenzothiazole (C7H5NS2) has been investigated by synchrotron radiation photoelectron spectroscopy (PES) in the gas phase. The valence region, C 1s and S 2p photoemission spectra have been measured. Comparison of the experimental results with theoretical ab initio calculations, performed for two possible tautomeric forms of the molecule, shows that only the thione form is present in the gas phase. Vibrational structure has been clearly observed in the valence photoemission spectra. In the C 1s spectrum the seven components due to the inequivalent carbon atoms in the molecule have been assigned on the basis of ab initio calculations. S 2p components have also been assigned. The photoemission results have been compared with previously reported photoemission measurements for 2-mercaptobenzoxazole.

The CCD image sensor converts the light impinging on the imaging surface into an electrical signal, a base supporting the slider and the CCD CCD image sensor and the CCD image sensor relative to the movement of the imaging surface, the piezoelectric actuator drive assembly of the slider CCD and the substrate, so that the driving force of the driving force generator is connected to the portion applied thereon and the broken line extends along the guide part on the imaging surface of the CCD image sensor.


Objective:In order to know the situation of noscomial infection(NI) in comprehensive hospitals,and to adjust the policy of prevention and control of NI. Methods: We invsetigated 1237 patients of NI in four comprehensive hospitals in Guiyang city in April,2000. Results: The total infection rate of NI was 8.6%. Higher risk population of NI was the patients aged more than 60 years or less than 10 years. Higher infectional department of NI was comprehensive department. Higher infectional location of NI was lower respiratory tract. The main pathogens of NI were gram-negative bacilli. Drug sensitive tests:the NI pathogens were commenly resistan to many antibiotics and the resisting rates were 50%-100%. NI patients stayed longer in hospital than no-NI patients (P0.01). So the treating costs for the NI patients increased. Conclusion:Total infection rate,the distribution and the pathogins of NI in Guiyang are similar to those reported from other countries.The key point of preverting and controlling NI is to prevent and control higher infectional departments,higher risk populations, and higher infectional locations; and emphasis should be payed on drugsensitive tests and identification of pathogens befor using antibiotics.


In this study, roughened Ni/Pd/Au-Ag alloy-plated Cu leadframe and two types of mold compounds (A and B) were studied in terms of button shear tests on the leadframe surfaces and package performance after assembly and after reliability stresses. The package reliability stresses include pre-conditioning at Moisture Sensitivity Level 3 (MSL3) with three cycles of reflow at 260 °C (peak temperature) according to the standard for automotive products, followed by 100 cycles of temperature cycling (TC), autoclaving (AC) for 96 hours, and TC for 500 cycles. The results show that the button shear force of Mold Compound A on the leadframe surface is much higher than that of Mold Compound B on the same leadframe surface at room temperature as well as after MSL3 pre-conditioning. The package using Mold Compound A shows positive results after all the stresses stated above, while the package using Mold Compound B shows no delamination after assembly but does show minor delamination after AC for 96 hours and gross delamination after TC for 500 cycles at the bottom side of a die paddle. It is understood that the roughened surface is only on the top side of the leadframe surface and the bottom die paddle surface is the normal surface. Thus, the interface between the bottom die paddle of the leadframe and mold compound is the weakest interface in terms of adhesion, and after stresses it is weakened further and shows delamination. This study shows that the mold compound plays a very critical role in the package reliability in roughened Ni/Pd/Au-Ag pre-plated leadframe packages.

5-(Bromoacetyl)salicylamide is an important intermediate of medicine and pesticide. 5-Acetyl salicylamide was brominated by bromine to give 5-(bromoacetyl)-salicylamide in high selectivity. The yield was 93.2% when the molar ratio of 5-acetyl salicylamide to bromine was 1 ∶ 1.05 at 5 ℃ for 12 h.


In this paper, the Henstock-Stieltjes integral (HS integral) of a function with values ranging in an $\ell_p-$space, with $0<p<1$, is defined. Results such as the uniqueness of the HS integral, the Cauchy-Criterion for HS-integrability, HS-integrability of continuous functions, linearity of the HS-integral, HS-integrability of a function over a subinterval, and the additive property of HS integral on subintervals are obtained.


This paper presents a new modulation method for matrix converters based on the indirect modulation model. During the switching period, the proposed modulation method uses a combination of only one active vector and a zero vector in the inversion stage to achieve minimum flux error, while in the rectification stage a single current vector is selected, according to the error of the input current vector angle. This reduces the number of switching sequences in the switching period, improving the accuracy of generating the output voltage vector especially in the low modulation index range. Supplementary, the direct control of the input current vector is implemented. The estimation of the angle of the input current vector is done by applying the inverse transformation, that corresponds to the applied active vector, to the output currents.


The sequence alignment is a fundamental problem in computational biology. Many sequence alignment methods have been proposed, such as pair-wise sequence alignment, multiple sequence alignment (MSA), syntenic alignment, constraint multiple sequence alignment, and etc. Among them, pair-wise sequence alignment is a most commonly used method. Recently, MSA is more and more important which has been used to solve many molecular biological problems. The sum-of-pairs MSA problem has been proved to be a NP-complete problem. A progressive algorithm was used to solve MSA problem which is based on the pair-wise sequence alignments. However, this progressive MSA has a problem. This problem may be solved by using three-sequence alignment as a basic step instead of pair-wise sequence alignment. Three-sequence alignment can be solved sequentially in O(mnl) time complexity and O(mn) space complexity, where m, n and l are the lengths of the sequences to be aligned. The complexities of three-sequence alignment limit its applicability. Hence, to reduce the complexities becomes an important issue. In this paper, we propose a parallel algorithm to solve this problem. Our parallel algorithm requires O((mn)/p) space complexity and O((mnl)/p) time complexity, where p is the number of processors. Both experimental results and theoretical analysis are presented. The experimental results show that our parallel algorithm is applicable and achieves a good speed up.


Although the application of composites can be found back to the mid-nineteenth century, but renewed interest in these materials has been emerged only in the last decade or so. Wood has been the major source of raw material particleboards and fibreboards, but recently, rice-wheat straw( RWS) has gained more attention of researchers to be used as an alternative of wood. In Pakistan the RiceWheat grain production in 2006-07 was 5438 thousand tonnes and 23520 thousand tonnes respectively. For every 4 tonnes of rice or wheat grain, about 6 tonnes of straw is produced. Around 43437 thousand tonnes RWS is produced in Pakistan. RWS is primarily composed of cellulose, hemicellulose, and lignin. Use of RWS as a feedstock for producing materials, fuels, and chemicals still has been inadequate due to a number of factors including capital costs, waste streams, energy consumption, production logistics, and the quality of the biomass feedstock. RWS contain a relatively large amount of vessel elements, sclerenchyma fibers, epidermal cells (Dermal tissues) and parenchyma cells as compared to wood. The outer thin waxy layer of RWS lowers their wettability with water based formaldehyde resins. In additional to this, straw has a higher content of hemicelluloses and ash, but a lower content of lignin compared with wood. Particleboards, medium and high density fiberboards like composite materials are mainly manufactured from wood using binders such as acid curing amino-formaldehyde resins, alkaline curing phenol-formaldehyde resins, using polyisocyanate adhesives. Wood-based materials including natural materials and composites are being used as construction materials for long and forest wood has been used in paper and wood-based panels industries. RWS have not been used before for Particleboards, medium and high density fiberboards manufacture with the use of conventional formaldehyde resins like urea-formaldehyde (UF) resins, melamine-urea formaldehyde (MUF) resins, phenol-formaldehyde (PF). Therefore, the main aim of this study is to review the literature on methods to improve the bondability of straw with conventional resins. The study will help in efficient utilizing wheat and rice straw as an alternate resource for the industrial manufacture of particleboards and fibreboards.


A major challenge in most object detection datasets is class imbal-ance. It is especially apparent in uncurated datasets where framesoriginate from a real-world setup such as a set of cameras col-lecting data from fixed locations. In that case, the dataset classdistribution mirrors the real-world distribution, causing a bias to-wards over-represented classes if used for model training. In thispaper we propose a synthesis technique for balancing the dataset,which exploits having sets of frames from the same camera view.The result is synthesized frames containing only rare objects, whileguaranteeing realistic object placement both in terms of scene con-text and perspective. We train a deep learning object detectionmodel on the augmented dataset and compare its performance toa model trained on the original, imbalanced dataset. Results showthat including the synthesized frames in the training results in asignificant performance boost for the rare classes.


Subject of this work is conceptual solution for the regulation of the Neretva river left bank upstream from the Metkovicbridge. Regulation of the Neretva river left bank, upstream from the Metkovic bridge, is necessary because of the negative impact that water stream has on the bank and erosion processes.Increased erosion process appear partly because of the unauthorized construction of the various small objects near and within the coastal line of Neretva River on this section. Erosion processes adversely affect valuable flora and fauna of the river area. In order to minimize the negative impacts it is necessary to regulate that part of the watercourse in order to revitalize present biology, flora and fauna.
Proposal of the conceptual design of this very complex problem will be displayed within the master theses work during which the selected water flow regulation by means of regulating river with the groins, walkways and retaining walls in order to stabilize the road adjacent to the watercourse.Groins will gradually and naturally form a new coastline threw the years, which will have positive impact on flora and fauna resources. Also groins will enable the creation of space for recreation of domestic people.


ABSTRACT Supplemental Nutrition Assistance Program (SNAP) participation has been demonstrated to improve household food insecurity, yet not all those who are eligible for the program participate. This article describes findings from both peer-reviewed and grey literature pertaining to factors that influence SNAP participation. SNAP participation has demonstrated benefits for low-income individuals and families for improving dietary intake, reducing food insecurity, and ultimately providing one strategy to alleviate poverty. The findings are described with a social science and behavioral lens in order to glean public health implications and recommendations from a broad array of literature. Factors influencing SNAP participation across the social–ecological model are discussed. Macro- and microlevel recommendations are made and actions applicable in targeted outreach, program, and organizational strategies are recommended.


This Article explores the connotation of the term "diversity" in the corporate governance sphere and the utility of such a connotation. To explore what the term has come to mean, this Article conducts a comparative analysis of how the term is used in the corporate governance context in the U.S., U.K., Australia, Canada, India, and Malaysia. Based on this analysis, this Article argues that the push for "diversity" (in the way it has come to be understood) on company boards needs to be re-examined and recommends that the SEC needs to define the term in accordance with its policy goals.


Tax collection and management system under the system of tax allocation had implemented for about ten years. Financial circles and academy pay close attention to the result. But they had different versions of the system reform. This paper researched the existing problems and the reason of tax collection and management system.The paper used the domestic experience and foreign experience for reference and proposed that the State Taxation Bureau andLocal Taxation Bureau should take the road to amalgamate in order to reduce the cost of tax collection and management,and improve the efficiency of collecting.


This study determined the operation parameters of a microfite antenna with textile substrate on curved surfaces for biomedical applications in Wireless Body Area Network (WBAN). It is an exploratory research in the form of technological development, of quantitative approach, divided in three stages: definition and physical and electrical characterization of the textile material; mathematical modeling of the antenna; and simulation. The results show the non-linear alteration of the antenna parameters as their curvature increases. Although feasible, antenna design for e-health applications through the WBAN requires application-centric development.


The work reported in this thesis is principally concerned with the experimental and theoretical behaviour of polypropylene- and high modulus polyethylene-reinforced cements in tension and in flexure. Polypropylene-reinforced cement has a proposed application as a thin sheet cladding material and developments in associated thin sheet fibre-reinforced cement technologies are discussed. Existing theories to account for the tensile and flexural behaviour of fibre-reinforced cements are reviewed. A comprehensive theoretical treatment is presented for the complete behaviour in loading-unloading-reloading in direct tension of a cement composite, reinforced by continuous, aligned fibres. The treatment is modified to account for the measured non-linear stress-strain behaviour exhibited by polyolefin fibres. A satisfactory comparison is drawn between theoretical and experimental results for residual strains, reloading moduli and energy absorption during an unloading/reloading cycle. It la argued that an existing approach for the prediction of the flexural load-deflection relationship of a fibre cement composite is inappropriate and an alternative 'crack development' approach is presented, which yields a more realistic comparison with experimental data from flexural tests on polyolefin-reinforced cement composites. The behaviour of specimens under cyclic flexural loading and in reversed flexure through zero is discussed. The theoretical developments are expected to be generally applicable to a range of fibre-reinforced brittle matrix composites.
