We consider the series expansion of the [Formula: see text]-Hardy inequality of [G. Barbatis, S. Filippas and A. Tertikas, Series expansion for [Formula: see text] Hardy inequalities, Indiana Univ. Math. J. 52 (2003) 171–190], in the particular case where the distance is taken from an interior point of a bounded domain in [Formula: see text] and [Formula: see text]. For [Formula: see text] we improve it by adding as a remainder term an optimally weighted critical Sobolev norm, generalizing the [Formula: see text] result of [S. Filippas and A. Tertikas, Optimizing improved Hardy inequalities, J. Funct. Anal. 192 (2002) 186–233] and settling the open question raised in [G. Barbatis, S. Filippas and A. Tertikas, A unified approach to improved [Formula: see text] Hardy inequalities with best constants, Trans. Amer. Math. Soc. 356 (2004) 2169–2196]. For [Formula: see text] we improve it by adding as a remainder term the optimally weighted Hölder seminorm, extending the Hardy–Morrey inequality of [G. Psaradakis, An optimal Hardy–Morrey inequality, Calc. Var. Partial Differential Equations 45 (2012) 421–441] to the series case.


Background Acute esophageal necrosis is an uncommon clinical disorder diagnosed on endoscopy as a black esophagus. It has a multifactorial etiology that probably represents a combination of poor nutritional status, gastric outlet obstruction, and ischemia secondary to hypoperfusion of the distal esophagus. It typically occurs in older males with comorbidities. Case A 37-year-old woman presented with diabetic ketoacidosis and hematemesis. At esophagogastroduodenoscopy acute esophageal necrosis was diagnosed. The treatment included fluid and electrolyte management, insulin, and a proton pump inhibitor. She improved and left the hospital on day 3. Conclusion Diabetic ketoacidosis can result in a profound osmotic diuresis, fluid loss, and hypoperfusion of the distal esophagus. This condition can then lead to ischemic injury and acute esophageal necrosis. Awareness of the possibility of its presence in young women with hematemesis and poorly controlled diabetes is important since early identification with esophagogastroduodenoscopy is necessary to prevent serious postnecrotic complications.


Knowledge management facilitates the firms and employees to deliver better products and services and hence achieve competitive advantages and profits. The issues of knowledge management have drawn much attention form industry and academia. However, few reports have been found available investigating how knowledge management is adopted and diffused in organizations. This paper adopts structural equation modeling to investigate employees' cognitions pertaining to knowledge management and their impacts on knowledge management activities based on Innovation Diffusion and Technology Acceptance Model with empirical data collected among the life insurance enterprises in Taiwan. The results indicate that perceived usefulness and subjective norm significantly influence the employees' attitudes toward knowledge management, and the attitudinal factor significantly affects knowledge management practice. The findings assist organizations to recognize the value and associated obstacles of knowledge management. This paper also presents the instrument and comprehensive model which provides directions for future research.


In the course of a project of determining the provenance of Aegean Bronze Age pottery with Neutron Activation Analysis 46 examples of Late Mycenaean pictorial pottery mainly deriving from the Pelo ponnese and Eastem Central Greece, but also from Macedonia, Cyprus and Western Anatolia were sampled and analyzed. The new corpus of analyses is presented and discussed tagether with 20 pieces of such pottery already analyzed by Perlman and Asaro. The Neutron Activation Analysis (NAA) Ieads to the definition of 9 chemically different groups. the samples from the Argolid two groups called Mycenae/Berba ti and Tiryns/Asine, which are al ready weil known from the analysis of regular Mycenaean decor ated pottery, can be differentiated, and this is interpreted as the re sult of the existence of two workshops producing pictorial pottery. One of these was presumably situated in Tiryns or its vicinity, which is corroborated by the fact that all newly analyzed pieces from this site belang to this group. In addition, the results show that pictorial pottery in the palatial and post-palatial period was pro duced on a regional basis in different parts of the Greek Mainl and. In the pictorial pottery found in other parts of the Eastern Mediter ranean, however, of all these mainland Greek groups the group Mycenae/Berbati clearly predominates.


A UV-spectrophotometric method has been developed for the quantitative estimation of atorvastatin in tablet. The present study describes development and validation of UV-spectroscopic method for estimation of atorvastatin in tablet dosage form and validation of newly developed method. During development of analytical method methanol: phosphate buffer (20:80), methanol: water (20:80), methanol: water (50:50), acetonitrile: water (10:90) were tried but drug was found to be soluble in methanol: water (50:50). Standard stock solution was prepared in methanol: water (50:50). The detection eave length (ëmax) was found to be 248nm. Calibration curves were prepared. The proposed method obeys Beer's law in the range of 5-15ìg/ml. Absorption maxima was determined with 10 ìg/ml by scanning in the range of 200-400nm. Percent recovery studies are in the range of 98.78%-100.36%. The method was validated in terms of specificity, linearity, accuracy, range, precision, repeatability, robustness, system suitability, stability of analytical solution. Results of analysis were validated statistically and by specificity studies. From that it was observed that there is no interference of blank, excipients during the estimation of drug in formulation. This shows the adaptability of the method for routine estimation of atorvastatin in tablet dosage form.


The order of words in a Greek sentence is much freer and less predictable than in most European languages. The author explains and illustrates the principles which govern word order in Greek. He finds three: the tendency of certain words to take a constant position; certain types of logical relation between the sentence and its context; and the tendency to adhere to familiar patterns. His three main chapters discuss word order dictated by lexical or semantic, by syntactical, and by logical determinants.

Worldwide about one billion pounds of maleic anhydride is used annually in the manufacture of a number of commercially valuable products, including unsaturated polyester resins, agricultural chemicals, and lubricating oil additives. Maleic anhydride is not found in nature. It was first prepared in 1834 by heating malic acid (hydroxy-succinic acid, a compound found in apples and many other fruits). Maleic anhydride was not available commercially until ca. 1930 when the catalytic air oxidation of benzene was begun by National Aniline and Chemical on an industrial scale. The estimated worldwide production in 1985 was 1023 million pounds coming from more than 35 plants varying in capacity from 6 million pounds to 170 million pounds annually.


In this paper, we propose a fast and efficient inter mode decision using support vector machine (SVM) for HEVC inter prediction. In the proposed algorithm, we use information such as MV variance, neighboring CU depth level and coded block flag (CBF) as features for SVM-based CU size decision; while MV variance, SKIP flag and RDO ratio for SVM-based PU mode decision. The experimental results reveal that the proposed algorithm can achieve average 29.6% reduction of computation time with 0.09% bit rate increment only, compared to the original HEVC inter prediction.


The essay reads Mary Tighe as reconstructing notions of late eighteenth‐century femininity through the aesthetics of her long poem, Psyche. While other scholarship has understood Tighe as appropriating a conventional gaze structure so often used and championed by canonical male poets, this essay argues that Tighe creates a new female, Romantic aesthetic through a shrewd refusal to take up that gaze structure as a poetic technique in her poem. In Psyche, she interrogates a sight‐driven sense of the world by using tropes of blindness that resituate her work in the space of less conventional, female epistemologies. Rather than privileging vision, the poetess privileges sensory experiences like speech and touch so as to undermine, deconstruct, and then circumvent the gaze structure altogether. Through these alternative sensibilities, Tighe creates a Romantic poetic aesthetic liberated from the constraints of feminine propriety and characterized instead by the expression of female desire and sexual agency.


Hypertensive disorders of pregnancy remain a leading cause of maternal and fetal morbidity and mortality [1]. There is no consensus on the relative efficacy and safety of the medications to treat severe hypertension in pregnancy and the most recent Cochrane review found insufficient data to recommend a specific drug [2]. The current drug choice is empirical and simplistic. Pharmacological agents have different mechanisms of action but they are often used interchangeably. Hence the choice of antihypertensive treatment is linked to the experience and familiarity of the clinician with the drug and it is not based on the features of the patients. The gold standard of medical treatment is based on blood pressure without considering maternal hemodynamic profile. Latest, maternal hemodynamic assessment has assumed a key role in the understanding, prediction and management of many severe complications in pregnancy: gestational hypertension, fetal growth restriction, and preeclampsia [3,4]. Noninvasive methods, such as maternal echocardiography, can give data about cardiac output and peripheral vascular resistance. A therapeutic scheme to treat hypertensive disorders in pregnancy based on cardiovascular parameters, other then blood pressure, has not been yet created. On this purpose, we would like to propose our vade mecum after many years of maternal hemodynamic studies, to choose the best fitted drug treatment aimed at the hemodynamic features of the patients. First we have made three simple rules:


Some advantages about growth and survival of mycorrhizal fungus with their hosts are described as a biotechnological alternative for making possible the compatibility of forestal production with environmental conservation. Mycelia propagation of mycorrhizal fungus is supported on laboratory or the nursery cultures in order to be used for inoculating coniferae plantules.


Parallel hole collimators which are currently routinely used in SPECT imaging were designed a few decades ago, when filtered backprojection (FBP) was used for tomographic reconstruction. Statistical reconstruction methods with precise modeling of the projection measurement offer a different standard, and the question of optimizing resolution - sensitivity tradeoff by choosing appropriate collimator aperture needs to be revised. In this paper we search for a parallel hole collimator which offers best performance in detection of hot lesions on a uniform background. To evaluate the image quality we use standard quantitative measures like the contrast recovery coefficient, coefficient of variation, and contrast to noise ratio. We also performed signal detection by human observers followed by Receiver Operating Characteristics (ROC) analysis for a few lesions close to the limit of visibility. Our results consistently indicate that optimal performance is achieved with collimators of sensitivity 6 - 9 times that of the conventional high resolution (HR) collimator. When the optimized collimator is applied, the image quality of the conventional image obtained with the HR can be achieved at scanning time or activity dose reduced by factor of 3.


Dynamic Adaptive Streaming over HTTP (DASH) was introduced to enable high video quality streaming over HTTP. DASH depends on the adaptation logic at the client to choose which video bitrate to stream from the content server for each chunk. For clients receiving video over a cellular network, the cellular first hop tends to be the bandwidth bottleneck and can exhibit significant swings in available bandwidth. In this paper we develop and evaluate a Dynamic Adaptation for mobile Video Streaming (DAVS), a technique that can be used within DASH adaptation to handle the significant bandwidth variability experienced by cellular mobile clients. In our scheme the main innovation is that the client chooses a bitrate based on whether the playout buffer occupancy (BO) falls below or above a dynamic threshold. In addition, the scheme attempts to minimize bitrate switching by again delaying a change of video bitrate selection by a window of time - that is also dynamically determined. We evaluate the performance of DAVS over real traces collected from a mobile network operator. DAVS shows better performance over different video streaming metrics. Furthermore, It increases the QoE by a range 15% – 55% compared to benchmark algorithms.


ESTABLISHING THE CULTURAL CONTEXT. To set your watch, reply to a stranger's wisecrack, or write a piece of music is to partake of some culture. An observer wishing to determine which parts of what culture have thus been enacted faces a difficult task, however. That is the challenge the essays in this section seek to meet, and they must go about it without the guidelines—of comparison, function, repetition, or formal ideas—conventionally used to show how a broad culture is reflected within a particular religion, institution, ritual, or law, or expressed through events of obvious social consequence like a marriage or a revolution. For these general categories there are appropriate theories to test, predictable questions to ask, and special vocabularies to use. Spontaneous behavior and lesser issues may also reveal the content of a culture or the hidden tensions within it, but there are fewer accepted models on which to build an interpretation. Siamak Movahedi wants to explain the opposition to (and later acceptance of) daylight-saving time in Iran. To do so, he first uses survey techniques to connect the response of his informants to the change in time with their attitudes toward other issues, and he then employs a striking comparison between Iranian responses and those of Americans opposed to daylight-saving time. In each country he finds that there are two operative cultures, one sacred and one profane, sustaining two competing conceptions of time. (Articles by Du Toit, Lincoln, and Berg in the last issue of CSSH dealt with a number of profane uses of the sacred.) A culture can, of course, be in part defined by its perception of time and therefore of the past (see Rigby in 25:3; Wylie, 24:3; Cohn, 3:3; and Marcus, 3:2). Michael Roberts, interested in the relations of anthropology and history (like Hammel and like Cohn in 22:2), finds in the activation of historical memories a clue that explains the power of a reply suddenly spoken within the ritual enclosure of a Sri Lankan cricket match. Words that can sail across layered histories and competing cultures can have radical force (see Felstiner and Lincoln, both in 25:1, on revolutionary language but compare the incident in Sri Lanka with the one in India analyzed by Yang in 22:4). Even so, words are not the primary expression of a revolution in music; but Catherine M. Cameron takes the comments of composers seriously, Like Movahedi, she uncovers interlocking sets of values that form a cultural context, in this case one that favors avant-garde music by associating it with democratic change and American independence from European tradition. (For a contrasting approach, see Kasdan and Appleton, 12:1; compare also the discussions of style in Katz, 15:3; Kuper, 15:3; and Garvan, 3:1.) The review essays in this issue are also attentive to the complex difficulties of determining the cultural context that informs specific behaviors. Jane H. Hill


Background: Breast cancer in men is rare and requires therapy concepts including health considerations different from those in female patients. Case Report: We report on a 64-year-old male patient with metastatic breast cancer in the lung and cervical lymph nodes. Upon metastasis, initial adjuvant endocrine therapy with tamoxifen was changed to anastrozole. After 1 year of treatment, the patient was found to have rising prostatespecific antigen (PSA) levels, and diagnostic workup confirmed the diagnosis of early prostate cancer. Because of simultaneous progressive disease of metastatic breast cancer, chemotherapy with 6 cycles of docetaxel was administered resulting in a partial remission of both tumor types. The patient is currently treated with an endocrine combination therapy of fulvestrant, goserelin, and bicalutamide. He is in good clinical condition, and tumor markers for both tumor types are stable. Conclusion: Elevated PSA levels under therapy with aromatase inhibitors have been described in individual cases but always warrant a careful diagnostic workup to exclude prostate cancer as an important differential diagnosis. Genetic counseling has to be taken into consideration in the case of male breast cancer as well as in the case of coincidence of different tumor types, such as breast and prostate cancer, due to the possibility of e.g. BRCA mutations in these patients.


The Visual Analysis System (VAS) was developed to couple emerging successes in data mining with information visualization techniques in order to create a richly interactive environment for information retrieval from the World Wide Web. VAS's retrieval strategy operates by first using a conventional search engine to form a core set,of retrieved documents. This core set is expanded by crawling from links in these documents to form a much larger set. The link topology of the larger set is then examined using data mining techniques to identify pages likely to be both relevant to the query and reliable as sources of information. Information visualization techniques are used to display the filtered set in a form amenable to the use of perceptual processes to filter and guide further user directed search.

The essence of traditional family training culture is: "Tao", "Benevolence" and "Righteousness". Its connotation is: benevolence, righteousness, courtesy, wisdom, faith, loyalty, forgiveness, filial piety. It has many positive values for the cultivation of excellent moral character of contemporary college students.


We consider the problem of distributed detection of a common random signal. After evaluating the detection performance of the centralized detector, we propose two distributed detectors. Detector 1 employs energy detector at the local sensors and a monotone fusion rule at the fusion center (FC). Detector 2 uses a Sign detector at each local sensor and a two-sided test at the FC. Detector 1 performs better for the somewhat extreme cases where the number of sensors is very small. When the number of sensors is reasonably large, we prove that detector 2 outperforms detector 1 using the Kullback-Leibler divergence (KLD) and Stein's lemma. In fact, for sensor networks with a reasonable number of sensors, the performance of detector 2 is about equation as effective as the centralized case where no local quantization is made. We validate the derived results via numerical Monte Carlo Simulations.


Disease and phenology were compared in 2 wheat cultivars (Aroona and Spear) differing in disease resistance and maturity, at early (April-May) to late (June) sowing dates in 1991 and 1992. The cultivars had similar rates of leaf development but the longer season cultivar Spear averaged up to one leaf more on the main stem than the midseason cultivar Aroona, depending on sowing date. The extra leaf production which delayed flag leaf emergence on Spear compared to Aroona at early sowings was associated with lower disease levels in 1991. The occurrence of leaf rust may have diminished this advantage in 1992. Resistance to Septoria tritici in Aroona did not affect disease progress compared to Spear. A comparison of disease over a segment of accumulated thermal time revealed that in 1991, under average seasonal conditions, the earliest sowing experienced the most disease. In 1992, above average late spring rainfall occurred and time of sowing had little influence on disease over the same segment of thermal time. We conclude that a cultivar appropriate for early sowing on the south coast should exhibit increasing leaf production in response to early sowing. This can result in a reduction of disease severity on the upper leaves through disease escape.


There are a lot of mountain cities in western China. A large number of landfills in mountain cities in western China were constructed before the 1990s. Where these landfills are not adapted to modern needs, the landfills will be closed and renovated. The law of leachate transport must be studied in order to close and remediate them successfully. This paper provides a study of the Qilongcun landfill in Chongqing city in western China. The Qilongcun landfill is typical of those in mountain cities. The law of leachate transport in the landfill reflects the law of leachate transport for all mountain cities. The geological model was generalized for the Qilongcun landfill and a mathematical model was established. Then, the simulated density of leachate was compared with the actual density and the mathematical model was identified and adjusted. The correct mathematical model had been acquired when the simulated density of leachate approximates the actual density of leachate. The variation of leachate density was numerically simulated for inside and outside, northward, southward and both sides of the landfill, and the law of leachate transport was analyzed. The law is that the leachates move rapidly along faults and in the Quaternary strata and influx to low-lying land on the southward side of the landfill. The law supplies a basis to close and remediate other landfills of mountain city in western China. Resume: Il y a beaucoup de villes de montagne en Chine occidentale. Un grand nombre d'enfouissements des dechets dans des villes de montagne en Chine occidentale a ete construit avant les annees 1990. Ou ces enfouissements des dechets ne sont pas adaptes aux besoins modernes, les enfouissements des dechets seront fermes en haut et renoves. La loi de transport de leachate doit etre etudiee pour fermer en haut et les reobtenir par mediation avec succes. Le papier fournit une etude de l'enfouissement des dechets Qilongcun dans la ville Chongqing en Chine occidentale. L'enfouissement des dechets Qilongcun est typique de ceux dans des villes de montagne. La loi de transport de leachate dans l'enfouissement des dechets Qilongcun reflete la loi de transport de leachate pour toutes les villes de montagne. Le modele geologique a ete generalise pour l'enfouissement des dechets Qilongcun et un modele mathematique a ete etabli. Puis, la densite simulee de leachate a ete comparee avec la densite reelle et le modele mathematique a ete identifie et ajuste. Le modele mathematique juste avait ete acquis quand la densite simulee de leachate se rapproche a la densite reelle de leachate. La variation de densite leachate a ete numeriquement simulee pour l'interieur et exterieur, vers le nord, vers le sud et les deux cotes de l'enfouissement des dechets et la loi de transport de leachate a ete analysee. La loi est que le leachates se deplace le long des fautes et le mouvement rapidement dans la strate Q et l'afflux dans la cavite sur le cote vers le sud de l'enfouissement des dechets. La loi fournit une base pour fermer en haut et reobtenir par mediation d'autres enfouissements des dechets de ville de montagne en Chine occidentale.


ABSTRACT The local tetragonal distortions (α − α0) (where α is the angle defined as tgα = R⊥/R//, R⊥ and R// are the metal–ligand distances parallel with and normal to the C4 axis, α0 = 45° is the same angle in cubic symmetry) of (CrF6)3− and (FeF6)3− octahedral clusters in the tetragonal Rb2KGaF6 crystals are estimated by analyzing their electron paramagnetic resonance (EPR) zero-field splittings D. The results indicate that the two impurity octahedra and hence the host (GaF6)3− octahedra are tetragonally elongated. The distortion (α − α0) in magnitude differs from impurity to impurity because of the different sizes and natures of these impurities. These results are analogous to those in ABX3 and doped ABX3 perovskite crystals where the cubic-to-tetragonal phase transition is due to the rotation of BX6 octahedra associated with the release or elongation of B–X bond along the C4 rotational axis.


Abstract We draw on both life course and decision-making theories to examine decision strategies prior to moving to a continuing care retirement community (CCRC) and subsequent satisfaction following the move. Multivariate analyses drawing on panel data for a sample of 92 older adults (age 64 to 94) before and after their move to a CCRC show that frequent residential relocation in the adult years reduces the odds of considering staying in one's own home. Cognitive orientations at time 1 predict subsequent satisfaction with the move to a CCRC: mastery increases the odds, desiring age-integrated housing reduces the odds.


Earlier findings that human activated T blasts display HLA‐DR determinants have been confirmed. After phytohemagglutinin activation, Percoll gradient‐purified blast cells were cultured for two weeks in mitogen‐derived supernatants from human lymphocyte cultures. Using purified T blasts and internal labeling procedures, it was established that T blasts actively produced HLA‐DR‐like chains, as assessed by sodium dodecyl sulfate polyacrylamide gel electrophoresis. Further, HLA‐DR chains obtained from Epstein‐Barr virus‐transformed B cells and from T blasts of the same donor were compared. Two‐dimensional gel electrophoretic comparisons indicated a striking homology between 29 kD and 35 kD chains, obtained from the two different cell types. Peptide map analysis and preliminary amino acid sequence comparisons further supported this similarity. A more complete analysis would, however, be required to prove actual identity. The fact that human T blasts produce and display HLA‐DR molecules very similar, if not identical, to those present on B cells must then be incorporated into models discussing major histocompatibility complex‐restricted collaborations involving HLA‐DR molecules.


A new approach for direct determination of S‐adenosylmethionine (SAM), S‐adenosylhomocysteine (SAH), and methylthioadenosine (MTA) in urine was developed based on MEKC by using SDS modified with isobutanol in the presence of PEG‐300. Analytes were first extracted with grafted phenylborononic acid. Using a 50 µm internal diameter silica capillary of 32 cm total length filled with 0.05 M SDS, 0.05 M H3PO4, 5% (v/v) isobutanol, and 10% (v/v) PEG‐300, LOQ of 0.15 µM for SAM and SAH, and 0.2 µM for MTA was reached. Accuracy was 92% for MTA, 109% for SAH, and 105% for SAM, intra‐ and interday imprecision were <2.5 and ≤3%, respectively. The total time of analysis for one sample was 10 min. Analysis of 30 urine samples from healthy volunteers showed that the median SAM and SAH levels were 12.1 and 0.73 µM, respectively. MTA levels, which were determined in urine for the first time (according to our data), were 0.43 µM, and these values correlated well with the SAM level (r = 0.748, p < 0.01).


12 NOVEMBER 2005 • AMERICAN LABORATORY In the quest to develop innovative products, researchers are increasingly relying on computational technologies to help simulate the properties of new materials. Ultimately, scientists engaged in materials research aim to develop new compounds that can predictably be applied to a product development program. While there are many disciplines that contribute to the research of new materials, nanotechnology research offers the greatest opportunity to develop innovative compounds to significantly enhance products and quality of life for consumers.


The paper introduces a new method of digital image correlation by making use of the transitioning state of the digital micro-mirror device (DMD). The projector should be given an OFF time in order to introduce flashing light for dynamic imaging. The dark period between DMD's ON time is used to solve the saturation problem. Multiple captures are made during each projector cycle. The final unsaturated camera image can be obtained by combining all the images captured during that cycle. Experiments conducted demonstrate the success of the proposed method in performing digital image correlation for highly reflective surface.


This chapter looks at the stained-glass windows of the crossing and the choir clerestory of the Princeton University Chapel. On the east side of the two transepts and in the choir above the organ cases are four windows which together illustrate aspects of the great themes in the Book of the Psalms. The windows are composed of numerous little scenes that are literal illustrations of verses from the Psalms, or are scenes from the life of Christ suggested by the verses. The four lancets in each window are to be read from left to right, and the three panels in each lancet from top to bottom. The north transept features Psalms 147, 148 and 150, while the south transept shows Psalm 107. In the north side of the choir are Psalms 22 and 23, and in the south side is Psalm 91.


The purpose of this study, based on job characteristics model, is to study structural relationship among job characteristics, organizational trust and organizational citizenship behavior(OCB) for sports center employees. For this study, data were collected from those people who work for hotel, large private and citizens' sports facilities around Seoul, Korea. To analyze data, the study executed frequency analysis, exploratory factor analysis, and reliability analysis by using SPSS 16.0. Also AMOS 16.0 was used to execute confirmatory factor analysis. Finally, structural equation model and Aroian test were executed to verify the hypothesis and the mediation effect, respectively. As a result, the task significance, a sub-factor of job characteristic model, directly showed a positive effect on the OCB. And task identities, skill variety, task significance, and feedback directly showed a positive effect on organizational trust. Also, organizational trust directly showed a positive effects on OCB. Conclusively, organizational trust seemed to have complete mediation effects only between sports center employees' task significance, task identity, and feeddback among job characteristics and OCB as it showed positive effects to each one of them.


Stellar Imager (SI) will be a Space-Based telescope consisting of 20 to 30 separated apertures. It is designed for UV/Optical imaging of stellar surfaces and asteroseismology. This report describes details of an alternative optical design for the beam combiner, dubbed the Spatial Frequency Remapper (SFR). It sacrifices the large field of view of the Fizeau combiner. In return, spectral resolution is obtained with a diffraction grating rather than an array of energy-resolving detectors. The SFR design works in principle and has been implemented with MIRC at CHARA for a small number of apertures. Here, we show the number of optical surfaces can be reduced and the concept scales gracefully to the large number of apertures needed for Stellar Imager. We also describe a potential application of this spatial frequency remapping to improved imaging with filled-aperture systems. For filled-aperture imaging, the SFR becomes the core of an improved aperture masking system. To date, aperture-masking has produced the best images with ground-based telescopes but at the expense of low sensitivity due to short exposures and the discarding of most of the light collected by the telescope. This design eliminates the light-loss problem previously claimed to be inherent in all aperture-masking designs. We also argue that at least in principle, the short-integration time limit can also be overcome. With these improvements, it becomes an ideal camera for TPF-C; since it can form speckle-free images in the presence of wavefront errors, it should significantly relax the stability requirements of the current designs.


We have shown that the off-state degradation in GaN based metal-oxide-semiconductor high electron mobility transistors has three field dependent regimes. We have considered Al 2O 3 and AlO xN y as the gate dielectrics. The degradation is dominated by electron trapping near the drain edge at relatively low electric field; hole trapping followed by structural defects tends to dominate at high electric field. The structural defects may potentially be caused by an inverse piezoelectric effect when the AlGaN/GaN interface may relax partially. The hole trapping, in particular, at moderate to high electric field can lead to an anomalous trend. The off-state drain current bears the signature of the degradation. The transistor performance is found to deteriorate for all the cases independent of the degradation mechanism. The trapping contribution toward the degradation is partially recoverable; however, the structural damage is found to be permanent. It is also observed that both the gate dielectrics qualitatively suffer from the same degradation mechanism with oxynitride high electron mobility transistors showing higher resilience than their oxide counterpart.We have shown that the off-state degradation in GaN based metal-oxide-semiconductor high electron mobility transistors has three field dependent regimes.

The process implications of catalyzing coal with impregnated calcium on the production of Synthetic Natural Gas (SNG) were evaluated. An Illinois No. 6 was catalyzed with calcium at various treatment conditions and then gasified in a thermal gravimetric analyzer (TGA) to determine empirical relationships relating its reactivity to treatment and gasification conditions. Catalyzed coal was also gasified in a continuous bench-scale fluid bed steam/oxygen gasifier. Results of these tests indicate catalyzation eliminates agglomeration and substantially increases gasification reactivity. In addition, the calcium acts as a sulfur adsorbent. Process cost modeling studies indicated that the greatest economic potential for the utilization of catalyzed coal is to take advantage of the reactivity by utilizing a system for steam gasification of the coal using heat supplied by combustion of the gasified char in a separate combustor thereby eliminating the need for oxygen while maintaining production of a medium BTU gas. The results of this work are also directly applicable to gasification systems for electric power generation as well as for the production of synthesis gas for chemical production.


The lubricating properties of three different grades of lubricating oils were calculated and researched after the thermoelastohydrodynamic lubrication model of main bearings of ICE was established.The results show that the main bearing is in hydrodynamic lubrication state when three types of lubricants are used in the engine under low speed and low load operation conditions;under medium speed and load conditions,the main bearing still maintains lubrication state though oil film thickness decreases,oil film temperature rises,friction power increases;in high speed and load conditions,the bearing lubricated by CD5W/30 oil is in the boundary lubrication state,which indicates that the lubricant oil is not suitable for use in the model machine.


Thanks to the recent renaissance in R&D the outlook for an AIDS vaccine is more promising today than ever. The progress was achieved in laboratories and in clinical testing centers but was made possible by policies and practices beyond the domain of pure science that encourage collaboration capacity-building innovation and private-sector engagement. Those practices must be extended and expanded if we are to reach the goal of making an AIDS vaccine a reality. (Excerpt)


AbstractIn this study, the center composite design in response surface methodology was firstly applied to optimize the photocatalytic degradation of aqueous styrene under visible light. Twenty experiments were done by adjusting three parameters (initial concentration of styrene, concentration of catalyst and initial pH of reaction mixture) at five levels by the method of multiple variable analyses. Based on the experimental design, an empirical expression was firstly established and subsequently applied to predict the photocatalytic degradation efficiency of aqueous styrene under visible light. The results showed that the experimental photocatalytic degradation efficiencies are in accordance with the theoretically predicted values very well with a high correlation. The strongest interaction between the parameters assessed was concentration of catalyst /initial pH of mixture. Optimal experimental conditions for arbitrary aqueous styrene concentration of 115 mg L−1 were found initial pH 6.8 and catalyst loa...


Residual stresses throughout the cure cycle in thick filament wound tubes are analysed considering the effects of thermal expansion, chemical shrinkage, orthotropic viscoelasticity, and the gelation and cure process. Good correlation with measured strains is obtained, but only if gelation is modelled. It is shown that interlaminar stresses during the cure cycle are generally low. However, if three dimensional constraint is present, significant stresses can arise due to the relatively high bulk modulus of the material even in the partially cured state. Since the strength is low early in the cure cycle, it is postulated that these stresses may be responsible for delamination.


ABSTRACT As the use of screens holding projected images becomes more prevalent in contemporary stage design, concerns have been raised over the tendency for images projected on stage to draw attention away from the live actor — what Katie Mitchell has referred to as 'the lure of the screen'. Two productions performed by the final year acting students at Central School of Speech and Drama provided an opportunity to test some ideas around the use of still and moving projected image in stage design, attempting to control this lure. Projected image was key to the design of both shows, which were — to a greater or lesser extent — devised with the company in the rehearsal room and the performance space. A major function of these productions is to showcase the performers and the design needed to support this aim, which, it was generally agreed, it did. In this short article, I will share some thoughts on why that was the case, and how the design team achieved a result that was scenographically successful and yet enabled the audience focus to remain largely with the live performers.

Opportunities of scientific electronic journals and alternative models of publishing for scientific communication From electronic journals and alternative models of scientific benefit both publishing info-documentary institutions which have funding problems for subscription and researchers for science communication. This article reveals the results of sociological research carried out between December 2010 January 2011 at the Academy of Sciences of Moldova and 9 universities of the country on scientific communication. Study results show that researchers from Moldova consider that is very important to provide open access to scientific information, but about one third of the participants in sociological research are not determined or not accepted to publish their works in open access journals or in electronic archives.


This volume represents a bold undertaking. Medieval warfare is both a complex and wide-ranging theme, made more so by research work of recent years, work in which the editor and the remaining 11 contributors have all been heavily involved. Inevitably there are omissions. Keen explains in his introduction the lack of an in-depth treatment of the `Byzantine face of medieval war' due to lack of space, but provides a vital paragraph emphasizing how the Byzantine story stands as a reverse image of the rest of the book, declining when the rest of Europe was developing to its strongest point. The next six chapters take us through the various chronological phases of this development, with specialists showing us their wares. There is no obvious template for these surveys, with the result that some omit aspects one would like to know about for the sake of comparison. Gillingham, for instance, says next to nothing on the size and nature of armies in his period (c.1020± 1204), and is the only one to insert a large number of subheadings into his text. The contribution of Philip Augustus to French military organization and expansion is somewhat minimized by the divide being placed at 1200/04, but Housley' s chapter on c. 1200± 1320 shows clearly how thirteenth-century changes prepare the way for the more ferocious struggles of the later Middle Ages. Rogers con® nes his observations on the Age of the Hundred Years War to its two main protagonists, but does so in a wideranging fashion with plenty of examples and a repeat of his signi® cant argument on the chevauche e, though he includes less discussion of crucial ® fteenth-century developments. Edbury reveals clearly the differences between Muslim and western armies, and emphasizes the problem of manpower shortages for the latter, operating as they were away from home territories. These surveys will be of immense value to students and enthusiasts because they offer something not found anywhere else ± a scholarly (even without footnotes), up-to-date and readable overview of nearly a millennium of military development, whereby informality yielded increasing place to formality, and organized inter-state war took the place of random raids by war bands. The latter survived, but the medieval mercenary, as Mallett's chapter in the second, thematic half of the book (`The Arts of Warfare') shows, was essentially part of the rise of


In this work a blasting seismograph was tested on a vibration shaker controlled by a single-point laser Doppler vibrometer (LDV). A total of 43 tests were made to measure the transfer properties (transmissibility and phase shift) of the basic elements of the full monitoring chain and investigate the performance of the full system. The main elements of the seismograph are described by second order transfer functions with typical parameters calibrated through nonlinear fit of the measured responses. The resulting transfer function is used to compare the behavior of the tested seismograph with four theoretical seismographs representative of those used in blasting. Fifteen theoretical inputs are run through the transfer function of each seismograph to assess their steady-response. The error (expressed as gain) in the peak velocity has been assessed. It varies from -1.5 to 2.3 dB (equivalent to a transmissibility of 0.84 to 1.3, respectively) depending on the seismograph and frequencies of the input. The largest errors occurred for input signals with frequencies in the low (<32 Hz) or high ranges (>125 Hz), where the mechanical, electronics and digital parts of the seismograph modify the signals. Seismographs with the nominal transfer function described by DIN 45669:1:2010 are ranked with the smallest errors. Monitoring devices with transmissibility around one in a narrow bandwidth, in line with ISEE suggested criteria for amplitude response, involve large phase shifts at low and high frequencies, resulting in a worst performance. Introduction Digital seismographs are the most common vibration monitoring system used to assess compliance of vibrations from blasting with existing damage prevention criteria (AENOR, 1993; BSI, 1993; DIN, 1999; Siskind et al., 1980). They are composed by three orthogonally oriented sensors placed in a metallic case and connected to a recording-processing unit. The response of the seismograph (including the geophones and the processing unit) to the incoming ground motion is described by the complex frequency response or by its mathematical equivalent, transfer function (Wielandt, 2002). These are generally given as curves of the amplitude response (or transmissibility) and phase shift versus frequency. Transmissibility is the modulus of the frequency response showing at each frequency the factor by which the input is modified, whereas the phase response is the argument and gives the time shift between the output and input signals. The measurement of the phase shift on a vibration shaker by comparison to a reference transducer requires the same source of time for the system under calibration and the reference transducer (see ISO 1606321:2003). This is not a problem when the sensor is investigated alone as was made for geophones used in blasting by Farnfield (1996). But is more complicated when the phase response of the sensor and the processing unit is examined together. DIN standard (2010) and US Geological Survey (Hutt et al., 2009) force to measure the phase shift only in the primary or type (classification) tests to confirm that the requirements of the monitoring device have been meet. Monitoring transmissibility is simpler, as it can be carried out without connecting the seismograph and the reference transducer to the same data acquisition system. It has been measured for various seismographs (Fogelson and Johnson, 1962; Segarra et al. 2015a, b; Stagg and Engler, 1980), but the phase response has not, as far as we know. The seismographs used nowadays are qualified according to ISEE (2011) or German DIN 45669:1:2010 (2010) specifications. ISEE define tolerance bounds of the transmissibility of the apparatus as function of frequency, whereas the phase shift is only defined in terms of the maximum error produced in the peak particle velocity. DIN standard (2010), with a more general scope than blasting, provides the nominal transfer function of the seismograph, so both amplitude and phase responses are well defined. This information is usually provided for the devices used in seismological stations (Nanometrics, 2009; Nofal et al., 2015; Ueno et al., 2015), but has been little investigated for the whole seismograph. This prevents removing the instrument response from the signal or comparing the seismograph performance with design characteristics without measuring the phase response of the system. Experiments and instrumentation The experimental set-up used to measure the response of a seismograph (identified as S0) is shown in Figure 1 (left graph). The geophone's case was directly anchored to the vibration shaker. A hex lag bolt with a reflective adhesive on its head was set between both sensors to measure the velocity of the shaker motion with a laser Doppler vibrometer (LDV). The signal from the LDV is fed back to the vibration controller to correct, if necessary, the driven signal supplied to the exciter. The shaker table was set to vibrate under a vertical harmonic motion of constant amplitude of 10 mm/s (0.4 in/s) and single frequency; vibrations in the horizontal plane were discarded to minimize tilt-induced errors (Hutt et al., 2009). The frequency of the input motion was varied from 2 to 256 Hz at intervals of 1/6 of octave in 43 tests. An additional test was made at 315 Hz to investigate the response at very high frequencies which may occur when vibrations are monitored at very close distances to the blast (Dowding et al., 2016). Figure 1. Experimental layout (left) and flowsheet of seismograph S0 (right); fn is natural frequency, SC signal conditioner, AA anti-aliasing, ADC analog to digital converter. The LDV and the vertical geophone (the two horizontal geophones were disabled to avoid cross-talk on the vertical geophone) were connected to the digital unit of the seismograph S0 that processes and records the signals from both sensors. The flowsheet of the complete monitoring chain is shown in Figure 1 (right graph). The unit has a range of ±200 mm/s, a resolution of 0.006 mm/s and a sampling rate of 2048 Hz. In each test, the seismograph was triggered manually once the driven and control signals of the exciter converge. The unit stopped recording vibrations automatically 8 s later. The output from the vertical geophone was fed into channels 1 and 2. In the later the processing elements were set to a minimum: signal conditioner and an analog to digital converter (ADC). No aliasing is expected for the frequencies investigated (i.e. the highest frequency investigated is well below the Nyquist frequency, 1024 Hz), and no anti-aliasing filter was used in channel 2 to ensure that the output from this channel is essentially the geophone response (vgeo). Channel 1 includes all the processing stages typical of modern seismographs to modify the frequency response of the geophone (that we thus called vseis). These stages are colored in dark in the right graph, Figure 1, and are: an analog anti-aliasing filter, the ADC, and the digital equalization filter. The later stage is implemented in a vast majority of seismographs using electronic active circuits before the ADC. The recording unit was adapted to record the signal from the LDV in channel 7 (vldv), so the geophone and the LDV have the same time origin. This channel, as with channel 2, is composed by the signal conditioner and the ADC. Results All the signals were processed to remove offset. The steady-state complex response to a long enough input signal of a linear-time invariant system, like a geophone or a seismograph, is calculated as the ratio between the discrete Fourier transform of the output and the discrete Fourier transform of the input. These are for the geophone and seismograph, respectively: ldv geo geo V V H /  and ldv seis seis V V H /  Equations 1 and 2 where Vgeo, Vseis and Vldv are the discrete fast Fourier transforms of the signals recorded in the tests at each excitation frequency (the same subscripts used for the waveforms, right graph in Figure 1, are considered, but the lowercase v is replaced by an uppercase). The imposed motion is described from the output of channel 7 (vldv or Vldv) as in all the tests the frequency of this signal is the same than the excitation frequency, and its peak velocity differs from the nominal (10 mm/s or 0.4 in/s) by less than 1.2 % (the overall expanded uncertainty of the testing procedure considering other sources, can be fixed roughly, as 1.5 %). Figure 2 shows the complex frequency responses of the geophone (top graphs) and seismograph (lower graphs) using Equations 1 and 2, respectively; the amplitude or transmissibility is shown in left graphs and the phase shift in the right ones. At a given frequency, transmissibility above one indicates that the input is amplified, and values below one involves damping. The same sign criteria for the phase shift that it is used in earthquake engineering (Havskow and Alguacil, 2002) is considered here, and negative phases means a delay or a time-shift to the right as considered; phases of ±0.5 and ± indicate that the signals are in quadrature and completely out of phase with different polarity, respectively. The behaviour of the geophone at its natural frequency (8 Hz), with a transmissibility of 0.7 (upper-left graph, Figure 2) and a phase shift of -/2 (upper-right graph, Figure 2), is in line with typical values for this sensor (Telford et al., 1990). In order to show the effect of this sensor in the recorded waveform, the signals measured by the geophone and the LDV in tests at the band limits investigated are plotted, as an example, in Figure 3. It shows that vibrations of 2 Hz are strongly damped by the geophone (transmissibility of 0.06) that also shifts the output forward by 218 ms (i.e. /(2fm),  being the phase and fm the frequency, 0.88 and 2 Hz, respectively). At 315 Hz, distortion is limited, being the amplitudes of both signals and their relative position similar; top graphs in Figure 2 shows that transmissibility a

RENO TRYONO. Detection and Identification of Pineapple mealybug wiltassociated virus Causing Wilt Disease on Pineapple in Indonesia. Under supervised of GEDE SUASTIKA and SOBIR. Field surveys on pineapple wilt disease were conducted on pineapple production areas in Subang, West Java, Indonesia. The disease was characterized by severe tip dieback, downward curling, reddening, and wilting of the leaves which can lead to total collapse of the plant. The objective of the research is to identify the viruses causing wilt disease on pineapple in Indonesia. Tissue blot immunoassays (TBIAs) using two different antibodies specific to either Pineapple mealybug wilt-associated virus-1 (PMWaV-1) or PMWaV-2 (Agdia Inc., USA) successfully detected the viruses in leaf tissues from both symptomatic and asymptomatic pineapple plants. A reverse transcription-polymerase chain reaction (RT-PCR) assays using oligonucleotide primers specific to HSP 70 gene of PMWaV-1 and PMWaV-2 were also successfully amplified the regions succesfully. These finding indicated that both closteroviruses were associated with wilt disease on pineapple plants in Indonesia. Protein analysis by using sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) revealed that the viruses have a major structural protein with molecular mass of approximately kDa. Flexuous filamentous particles were also observed in electron microscopy preparations from infected plants. These results were in agreement with characteritics of the closteroviruses. Aligments of partial nucleotide sequences of the viral genomes exhibited 96 to 98% homology with that of PMWaV-1 and PMWaV-2 Hawaiian isolates as previously reported by Sether et al. (2001), respectively. Phylogenetic analysis revealed that Indonesian and Hawaiian virus isolates were belong to mealybugtransmitted closterovirus and closely related to Grapevine leafroll-associated virus-3 (GLRaV-3).

Background: A 24-year-old female had attempted suicide twice, at the age of 20 and 24, using tamoxifen.Case report: Subsequent to the first acute intoxication a development of bilateral ovarian cysts was observed. Cysts regressed spontaneously within 8 weeks. Five weeks after the second suicidal attempt, pregnant patient (15 weeks of gestation) was admitted to the hospital with vaginal bleeding and suspicion of miscarriage. The autopsy of the fetus did not reveal any gross abnormalities, whereas the microscopic examination demonstrated numerous foci of necrosis in the placental decidua. Other fetal membranes as well as the umbilical cord were normal.Conclusions:1.Acute intoxication with tamoxifen may be connected with the formation of follicular ovarian cysts.2.During pregnancy, intoxication with tamoxifen, may result in delayed miscarriage.

SOME READERS WILL NO DOUBT RECOGNIZE in the title chosen for this article a commonplace, since it treats of what is perhaps the most critical and overworked theme regarding Antonio Genovesi. But it suggested itself to me since there is a need to attempt a revision of a historical thesis which does not seem to have lost its influence even today. I have in mind the introductory pages of the synthesis that Giovanni Gentile dedicated in 1903 to the His tory o f Italian P h i l o sophy f r o m Genoves i to Galluppi, 1 which is perhaps the only book that makes use of Genovesi 's name to indicate an entire period of Italian culture. However, this does not have much significance since Gentile, who was at that time intent on elaborating his Rebir th o f Idealism 2 and fresh from his attempt to bring up to date Bertrando Spaventa's thesis of the "circulation of European thought ," saw in the "historical process by which there gradually came to be elaborated that empiricism initiated by Genovesi" a break, a moment " n o t directly fastened as one link to another link o f a chain in the history of Italian philosophy from Rosmini onwards ." As is well known, this historiographic statement was a continuation of Spaventa 's cultural polemic and of his classical formulation of this thesis in the lectures with which he inaugurated his own teaching at the universities of Bologna and Naples in 1860, the very year of the unification of Italy. It is easy to find in the cultural situation of Naples before and after 1848 the grounds for Spaventa's rejection both of the still dominant empiricism and even more of the eclecticism jus te -mi l ieu inspired by Victor Cousin and Frangois Guizot. Spaventa's translation of Hegel's philosophy of history and history of philosophy into Italian terms corresponds to his revaluation of the "providence" of Vico and to his reinterpretation of Rosmini and Gioberti. Gentile did not disassociate himself


Surge tanks and air chambers are the most useful solution to deal with water hammer in water transmission systems (WTS). The optimal design of these protective devices can be effective in reducing the costs of constructing and operating a water transmission system. In this article, some software with the capability of simulating and optimizing these protective equipment is presented. To simulate the behavior of the system in the transient condition, the characteristic method was used. To optimize the number, dimensions and location of the surge tanks and air chambers, the genetic algorithm was employed. Constraints of the problem included the control of negative and positive pressures within the permissible range to prevent the cavitation and water hammer. To test the performance of simulation and optimization models, a well-known water transmission system in the previous research was selected as a case study. The results indicated that the critical heads were damped to a safer and allowable range; also, the total cost of the surge tanks and air chambers was reduced by 17% by the proposed method.

Total chip size has additional area of about 18% for BIST circuit.


I created a Shanxi Province GIS -based Planning Support System (SPGPSS) for transportation and industrial plant location studies of the cokemaking sector in Shanxi Province. By integrating database, map viewer, scripts, and professional models in the GIS environment, on the provincial level, I designed the SPGPSS to have capabilities of optimizing plant locations, transport routes and modes under the different scenarios and computing the corresponding cost, energy consumption, and pollution emissions in the transportation process. Policy makers and industrial organizations can utilize the SPGPSS to value the economic and environmental impacts from different policy possibilities and assist their planning decisions on location rearrangements and structural changes. On the plant level, a plant manager can use the SPGPSS to conduct spatial analyses and multi-plan valuations for an individual plant in the planning of transport routes and new plant location. By the applications of SPGPSS, I tested my hypothesis that combining cokemaking plants into several large-capacity plants or industrial parks is preferable to having them distributed throughout the area. From the perspective of total cost, the large-capacity plants and industrial parks instead of the distributed small-capacity plants would reduce the total cost both from the transportation and cokemaking process. From the perspective of total energy consumption and pollution emissions, however, the large-capacity plants and industrial parks would increase the total energy consumption and pollution emissions. Thus, my hypothesis is only partially proven. Thesis Supervisor: Karen R. Polenske ' Title: Professor of Regional Political Economy and Planning Thesis Reader: David M.

The microjet electrode (MJE) is characterized as a detector for high performance liquid chromatography (HPLC). Voltammetric measurements of the oxidation of hydroquinone (HQ) allow mass transport to be determined for the MJE detector configuration, and the factors controlling the conversion efficiency of the device to be well understood. The current-time response to the flow injection analysis of volumes of solution in the 10–80 μL range has been established, and the limit of detection of this method has been determined. The latter was found to approach that of UV absorbance measurements, which is particularly encouraging, given that HQ has a relatively strong chromophore (e=2 290.8 cm−1 mol−1 L). This detection system is a robust and simple arrangement with the capability of analyzing large volumes of eluent at typical analytical HPLC flow rates.


Abstract. Suryanto P, Sadono R, Yohanifa A, Widyawan MH, Alam T. 2021. Semi-natural regeneration and conservation in agroforestry system models on small-scale farmers. Biodiversitas 22: 858-865. The regeneration capacity can provide an overview of the abundance of species so that it can be used to determine the potential and opportunities for the sustainability of agroforestry systems. The purpose of this study was to determine the capacity of semi-natural regeneration in agroforestry system models for small-scale farmers. The study was carried out in Banaran Sub-district, Playen District, Gunungkidul Regency, Special Province of Yogyakarta, Indonesia. The observation was conducted on plant diversity, floristic composition, and agroforestry contribution. The results showed that the mixed cropping (MC) model had a higher total of individuals and diversity compared to the trees along with border (TAB) model in the sapling and seedling level. The MC model was relatively shorter to the waiting time of harvesting compared to the TAB model. The MC models weakness was the relatively high competition and the lack of opportunities to growing annual crops. The TAB model had an advantage in developing annual crops in an agroforestry system, while longer in waiting time for harvesting perennial crops. This study recommends annual pruning in the MC model for optimal stand growth, while in the TAB model, it is the enrichment planting in sapling and seedling levels.


We consider two different approaches to model growth of CO2 hydrate, phase field theory and a model based on cellular automata. The two approaches are applied to simulations of hydrate growth from supersaturated aqueous solution of CO2. The thermodynamic models for the solution properties are derived from experimental solubility data while the hydrate thermodynamics is based on adsorption theory with reference properties derived from molecular simulations. We show that the cellular automata approach has the benefit of being much more computationally efficient, and are still giving results which are consistent with results from the phase field theory.

Because of the non-uniformity of sensitive materials, there are serious non-uniformity of the infrared focal plane arrays (IFFPA). In practical applications, the two-point correction (or multiple-point) is widely used, but the non-uniformity caused by the time drift results in greatly reduced infrared imaging. Currently, the correction based on the sense attracts the interests of researchers, which requires the target motion scenes, and narrows the range of applications and produces the misconvergence phenomenon. The paper proposed a new non-uniformity correction algorithm based on the two-point correction combined with the information of scene, which can eliminate the non-uniformity of the IFFPA, time drift, and restrain salt & pepper noise too.

Co-morbid mental health conditions such as anxiety, depression and fear avoidance are often associated with chronic pain. This novel study aimed to explore the impact of osteopathic treatment on several psychological outcome measures relating to anxiety, depression, mental health and fear avoidance for a chronic pain population receiving osteopathic treatment over a 2-week period. The findings show that there were significant reductions in anxiety, pain, mental health dysfunction and improvements in self-care. These results are promising, and it is suggested that now a full-scale randomised controlled trial should be conducted.

A multifactorial in-depth study of 78 placentas obtained during delivery of HIV infected women in St. Petersburg between 2009 and 2011. We studied clinical anamnestic and laboratory parameters on the basis of the retrospective analysis, respectively, in 78 HIV-positive postpartum women (mean age 27,1±4,1 years) and their newborn children, of whom 12 have mother-to-child transmission of HIV. Most of the women who gave birth to infected children who were users of psychoactive drugs all took place co-infection with hepatitis C virus, about half of them were observed chronic urogenital infections. The complexity of communication, contacts instability did not allow any of the women who have realized the vertical transmission of HIV, antiretroviral therapy to conduct in full. In obstetrical establishment turned 11 women, but due to the onset of labor and/or premature rupture of membranes that are not allowed to use the elective caesarean section as a method of prevention of vertical transmission of HIV. All infants were signs posthypoxic encephalopathy. It was noted that in HIV infection in the placental tissue is imbalance between pro-angiogenic (VEGF, bFGF, CD31) and anti-angiogenic (TGF-β1, Tsp-1) factors in favor of the latter, which is the basis of a dissociated maturation chorionic villi and chronic placental insufficiency. With the implementation of intrauterine infection of HIV in placental tissue sharply reduced macrophage content, primarily CD68+ and, to a lesser extent, CD14+. Violation placental barrier greatly facilitates and determines the penetration of HIV to the fetus. In this case, targeted prevention, treatment for opportunistic infections and drug correction of placental insufficiency in HIV-infected women should, obviously, be regarded as justified pathogenetic approaches to reduce mother-to-child transmission of HIV.


In this paper we report on the content of major minerals (calcium, magnesium, sodium, potassium, iron and zinc) in the nature yoghurt (without sugars) and three yoghurts added with date powders. The latter's were from three dry date varieties (Mech-Degla, Degla-Beida and Frezza). The elements determination was carried out using atomic absorption spectrometry after mineralization processing. Total mineral content showed a great difference between the yoghurt nature and yoghurts enriched by date powder fruits. In the yoghurts added with date powder, following results were found (in mg/Kg): calcium (2213.31-2938.67), sodium (783.37-959.36), potassium (725.68-771.77), magnesium (169.54-267.85), iron (9.6-11.52), zinc (1.29-7.93). Concerning the natural yoghurt the values obtained were (in mg/Kg): calcium (1950.41), Sodium (684.72), potassium (540.58), magnesium (132.16), iron (5.26), zinc (0.35). These results are in positive interrelationship with those of the rheological properties.


Complex systems studies demand multidisciplinarity of domains and representation multiformalism. We propose a distributed simulation approach based on the notion of virtual system which allows to disregard multiformalism and multidisciplinarity. This abstraction uses encapsulation. We would like to notice that we do not deal with distributed simulation synchronisation. We assume that the corresponding primitives are available. The main problem we are concerned with is the organisation of the complex system according to the way it is made of. For this, our contribution emphasises hiding information. To do it, we firstly propose a virtual system formal definition. Then we define its coupling rules since the bottom-up approach can be used. Next we give a virtual system structure, then we tackle interoperability between these systems as a consequence of virtual systems and finally we compare our approach to that of Michel and Wiels (1997).

Patterns in spatial and trophic resource partitioning in the fish community of the Georges Bank region are identified, accounting for size-based changes in diets. During autumn and spring, this community is divided into geographic assemblages of species that have high spatial overlap. Similarity in spatial distribution is primarily related to similarity in depth preferences, and seasonal differences in species composition within assemblages are related to migrations. There is also important trophic structure within the Georges Bank community separating predators based upon prey size and location in the water column. Ontogenetic changes in diets are an important feature of the trophic structure in this system, particularly in the major piscivores. Seasonal changes in trophic structure reflect both predator and prey migrations. Dietary overlap among predator types is independent of either spatial overlap or depth preferences. There is spatial segregation within trophic guilds, and this spatial partitioning ...


In this paper the task of obtaining flutter derivatives and the computer evaluation of flutter speed was carried out for a cable stayed bridge with a main span of 658 m to be designed over the Ria of La Coruna in Spain. The bridge will be located in a very windy site and therefore some studies are required to find out the safety level against flutter aeroelastic phenomena. The set of eighteen flutter derivatives is important information required to carry out aeroelastic analysis aimed to identify the safety level of cable supported bridges against wind induced phenomena. In the case of flutter derivatives are the components of the aeroelastic damping and stiffness matrices that relate the lift, drag and moment forces to the vector of displacements and velocities of bridge deck. So far flutter derivatives are usually obtained by testing a reduced model of a deck segment in a wind tunnel. For doing that, two different alternatives exist: forced vibration approach or free vibration approach. In this occasion the free vibration approach with the sectional model of the deck supported by eight vertical and four horizontal springs was used and by carrying out tests for different speed flow. The complete set of eighteen coefficients A * i, P * i, H * i (i = 1,…6) was identified. Once flutter derivatives are obtained, flutter speed of the complete bridge can be calculated as it was explained in Jurado and Hernandez (2000), by the computational solving of a non linear eigen-problem which comes from the dynamic equilibrium equation for the deck.


The paper offers an answer to the question given by the title, starting from the revision of some specific elements of the appearance of the philosophical counsellor in the business and organisational environment, but also of the coaching as a service for the leaders, and it presents the characteristics of each one. The work makes a comparative analysis between coaching and philosophical counselling to observe the similarities and differences between the two applications that can act successfully in the field of building effective leadership in the business field. The concept of philosophical leadership is presented as a result of the application of philosophy in the business area. It leads implicitly to launching a collaboration proposal between the two practices, which can be materialised by issuing common services for the leadership, but also by taking over some specific tools from philosophy, now implemented in practice in the organisational and business area.


Chiral azaheterocycles substituted a to nitrogen represent the core unit of a wide range of alkaloids and biologically active compounds. They also play an important role as key targets for the pharmaceutical industry. Consequently, the stereocontrol of carbon centers embedded in these azaheterocycles is a permanent synthetic task for organic chemists. In this regard, we have developed an alternative and conceptually new synthetic approach to a variety of 2-heteroaryl cyclic amines and 6-aryl piperidin-2-ones which is based upon the asymmetric reduction of chiral endocyclic enenydrazides bearing a (S)-methylprolinol chiral auxiliary (SMP). This new synthetic methodology has then been illustrated by the total synthesis of S-(‑)-Anabasine and the stereoselective synthesis of cis-2,6-diarylated piperidines in high yields and high level of enantioselectivity.


The VLE data of 85 points for a system of ethyl acetate–ethanol–toluene were measured at atmospheric pressure. The results were examined by boilling-point calculations using two forms of the Wilson equation: one with constants of constituent binary systems and the other with constants from a least-squares fit minimizing the Q-function(gE⁄RT=Σxilnγi) of the ternary data. Two binary systems, ethyl acetate–ethanol and ethanol–toluene, show minimum azeotropic points. The normal boiling point of toluene is much higher than the boiling points of the other two substances by 32–3 K. Because the system had a complicated behavior, calculations using the Wilson equation had difficulty to accurately cover the entire area of compositions.

A method for time-frequency analysis is given. The approach utilizes properties of Gaussian distribution, properties of Hermite polynomials and Fourier analysis. We begin by the definitions of a set of functions called Harmonic Gaussian Functions. Then these functions are used to define a set of transformations, noted T_n, which associate to a function ψ, of the time variable t, a set of functions Ψ_n which depend on time, frequency and frequency (or time) standard deviation. Some properties of the transformations T_n and the functions Ψ_n are given. It is proved in particular that the square of the modulus of each function Ψ_n can be interpreted as a representation of the energy distribution of the signal, represented by the function ψ, in the time-frequency plane for a given value of the frequency (or time) standard deviation. It is also shown that the function ψ can be recovered from the functions Ψ_n.


Ethics is considered among professionals and academics as an important competence for advertising. Not surprisingly, in the context of the European convergence, the subject of ethics is mandatory in the new degree of advertising. However, American studies on the effects of ethical training on professionals' attitudes and behaviors are not conclusive. This study assesses the impact of ethics instruction on the sensibility increase to four dimensions of professionalism (cognitive-technical, social, affective-emotional and ethical). Our course has improved students' attitudes, particularly towards social skills, especially important in a profession which emphasizes the relational competences.


: In order to ascertain whether the use of drugs as feed additive for fish may cause drug resistance of bacteria in the intestinal tract, viable counts and bacterial flora in the intestine of yellowtail cultivated with the feeds in the presence or absence of various drugs, drug resistance of the flora were determined. Viable counts in the intestine were lowered remarkably by the administration of each drug, suggesting that bacterial growth in the intestinal tract was inhibited by various drugs. Bacterial flora in the intestine consisted mainly of coryneform bacteria, Staphylococcus and Bacillus regardless of whether drugs were administered or not. In these floras, significant differences could not be observed for their resistance to respective drugs among the isolates from fish cultivated with feeds containing or not containing each drug. In addition, these floras mainly showed resistance to various combinations comprising from one to seven drugs; moreover, the majority of resistant strains were multidrug-resistant.

The concept of chaos, which has entered the literature since the 19th century, has been used for the protection of information with the development of information technologies in recent years. Chaos circuits are frequently used in secure communication systems because of its unpredictability and ease of modeling. In this paper, real-time fuzzy control method was used for master-slave synchronization of Rucklidge chaotic circuit. Also, sinusoidal signal and image encryption were used for application of secure communication process in LabVIEW platform. Data acquisition system was used to implement real time application. Fuzzy control performed synchronization at the end of the specified period and image encryption and decryption were successfully obtained in the developed system.


Universal Filtered Multi-Carrier (UFMC) is a versatile fifth-generation communication technology that can be utilized in Internet of Things and Machine-to- Machine (M2M) communication to enhance connectivity and efficiency because of its spectral efficiency, low power consumption, reliability, and flexibility. The Internet of Things and Machine-to-Machine (M2M) communication enable devices to talk to each other, gather data, and make the world smarter and more efficient. However, the drawback of UFMC systems is they exhibit a very high peak -to-average-power-ratio which causes system Lower and latency on communication. Therefore, to lower the high peak -to-average-power-ratio of the UFMC system, this project proposes an efficient hybrid PAPR reduction approach that combines both non-linear companding techniques and precoding techniques. Key Words: Peak-to-average power ratio (PAPR), Hybrid PAPR reduction Techniques, Precoding Techniques, Non- Linear Companding Techniques (NCLTs), Universal Filtered Multi-Carrier (UFMC).


The elemental compositions, sizes, structures, and /sup 239/Pu contents were determined for 299 plutonium-bearing particles isolated from airborne particles collected at various locations in the exhaust from a nuclear fuel reprocessing facility. These data were compared with data from natural aerosol particles. Most of the collected particles were composed of aggregates of crustal materials. Seven percent of the particles were organic and 3% were metallic, viz., iron, chromium, and nickel. High enrichment factors for titanium, manganese, chromium, nickel, zinc, and copper were evidence of the anthropic nature of some of the particles. The amount of plutonium in most particles was very small (less than one femtocurie of /sup 239/Pu). Plutonium concentrations were determined by the fission track counting method. Only one particle contained sufficient plutonium for detection by electron microprobe analysis. This was a 1-..mu..m-diameter particle containing 73% PuO/sub 2/ by weight (estimated to be 170 fCi of /sup 239/Pu) in combination with Fe/sub 2/O/sub 3/ and mica. The plutonium-bearing particles were generally larger than natural aerosols. The geometric mean diameter of those collected from the mechanical line exhaust point where plutonium is converted to the metal was larger than that of particles collected from the wet cabinet exhaust (13.7 ..mu..m vs. 4.6 ..mu..m). Particles from the mechanical line also contained more plutonium per particle than those from the wet cabinets.

The flower mountain petroglyph is the expression of the spirit of Zhuang nationality forefather,conveying their desire for survival formed by the combination of primitive religion and sorcery thought,demonstrating the close connection between the source of art and emotional driving force and human's original adoring consciousness of life.Through the mountain petroglyph,ancient people of Zhuang nationality were close to and mingled with the inextricable universe.Therefore,petroglyph is the deposit of Zhuang people's emotions and perception in the long-range contact with Nature,land,mountains and rivers;resulting in the aesthetic theory that man is an integral part of nature;the female person's silhouette described in petroglyph reflects male's effective cognition of the internal and external reality,where female is orientated by traditional culture,embodying the male-dominating society's molding and stipulation to the female.


Abstract Caring is a positive social act, but can it result in negative attitudes towards those cared for, and towards others from their wider social group? Based on intergroup contact theory, we tested whether care workers' (CWs) positive and negative contact with old‐age care home residents (CHRs) predicts prejudiced attitudes towards that group, and whether this generalises to other older people. Fifty‐six CWs were surveyed about their positive and negative contact with CHRs and their blatant and subtle attitudes (humanness attributions) towards CHRs and older adults. We tested indirect paths from contact with CHRs to attitudes towards older adults via attitudes towards CHRs. Results showed that neither positive nor negative contact generalised blatant ageism. However, the effect of negative, but not positive, contact on the denial of humanness to CHRs generalised to subtle ageism towards older adults. This evidence has practical implications for management of CWs' work experiences and theoretical implications, suggesting that negative contact with a subgroup generalises the attribution of humanness to superordinate groups. Because it is difficult to identify and challenge subtle prejudices such as dehumanisation, it may be especially important to reduce negative contact. © 2016 The Authors.

The discharge performance of an impinging-type injector for cavitating flow has been evaluated. The predicted discharge coefficient for cavitating flow agrees well with the measured data showing less than 2% discrepancy. For the case of non-cavitating flow analysis, the disagreement between CFD results and the experimental data is 8%. The discharge coefficient for the cavitating flow decreases with decrease in the Reynolds number. On the other hand, it increases slightly as the Reynolds number increases for the non-cavitating flow because of the reduced viscous effect. The incipience of cavitation is predicted to occur around the cavitation number of 1.3 for fixed Reynolds number flow. In this environment, the discharge performance is proportional to the cavitation number for cavitating flow while it is independent to the cavitation number for non-cavitating flow regime.


In this paper, the thermohydraulic performance of a reciprocating room temperature active magnetic regenerator (AMR), with gadolinium (Gd) particles used as a magnetocaloric material (MCM) and water used as a working fluid, was numerically investigated. A two-dimensional transient flow model was developed using COMSOL Multiphysics, in order to determine the water flow distribution in two AMRs of cross and parallel Gd particles distributions for different water inlet velocities of 0.06 m.s-1, 0.08 m.s-1 , 0.1 m.s-1 and 0.12 m.s-1. The Gd particles have a radius of 1.5 mm and a distance from one another of 0.9 mm. Based on the simulations results of the first model, a two-dimensional transient coupled flow and heat transfer model was then developed using COMSOL Multiphysics, in order to characterise the convective heat transfer in the AMR of cross Gd particles distribution for the same water inlet velocities.
