There are many influencing factors in the melting process of polymer pellets in twin-screw extrusion. For the extrusion process with specific screw configuration and material, the influencing factors are summed to six ones, which are investigated by the phase change fraction method respectively.


This paper discusses the background reduction and rejection strategy of the Cryogenic Dark Matter Search (CDMS) experiment. Recent measurements of background levels from CDMS II at Soudan are presented, along with estimates for future improvements in sensitivity expected for a proposed SuperCDMS experiment at SNOLAB.


Compound flocculants in latex wastewater treatment was prepared by compounding PAFC,CTS and red clay.Effects of flocculant component ratio,dosage,stirring intensity to turbidity removal rate of latex wastewater and removal rate of COD were studied.Results showed that when mixing at the speed of 300 r/min within 2 min or at the speed of 80~100 r/min within 5min or at the speed of 15~25 r/min within 10min,mass ratio of PAFC: CTS 1: 0.16,dosage 6 mL/L,dosage of red clay 0.09 g/L,and then subsided by 10min,the removal rate of wastewater turbidity and 24 h COD was above 98% and 80% respectively.The method has reduced about half of drug dosage which was compared to using PAFC alone.Flocculent appearance shape was observed by SEM and flocculation mechanisms were discussed.After introducing CTS to flocculation,the charge neutralization of PAFC can be kept when flocculation and interparticle bridging performance of CTS's marcromolecular chain can be developed,which can improve the flocculation highly.


Founded in December 2014, the IEEE Control Systems Society (CSS) Technical Committee on Smart Cities (TC-SC) aims to address challenges at the urban and semiurban scales of future smart sustainable cities (which, according to Boyd Cohen [1], are more intelligent and efficient in the use of resources), resulting in cost and energy savings, improved service delivery and quality of life, and reduced environmental footprint. This TC is positioned to take advantage of its members' vast knowledge of systems and control to tackle a variety of topics that have potentially significant societal impacts (for example, smart mobility, smart living, and smart environments), which fit perfectly in Deloitte's smart-city framework [2] for quality of life, economic competitiveness, and sustainability.


Application development has progressed along with the rapid digital transformation. The stakeholders will focus more on cutting operational costs with optimal application quality and security. The DevSecOps approach provides solutions for reducing costs in the software life cycle, increasing software product quality and security. Public Company Logistic Agency (PCLA) is like other companies that must be adaptive to new technology. PCLA has an IT Division in charge of providing technology to support business. Application development by the IT Division has several problems, including application projects that mostly exceed the time, significant changes and additions during UAT, and applications that have much vulnerability. A transformation to the DevSecOps approach is needed to address these problems. In this paper, a Systematic Literature Review (SLR) was used to select journals that matched the study topic to obtain the character and transformation phases of DevSecOps in various case studies. A mixed-method approach aims to collect and analyze data companies in the software development lifecycle. For academicians, this study provides a new understanding of application development in a state-owned enterprise based on a sequential approach and their suitable solutions from the DevSecOps approach. For practitioners, the findings provide potential lessons learned and guide a state-owned enterprise to transform to the DevSecOps approach.


This report presents the initial results of the quantitative phase of the hydrothermal testing program on the geochemical behavior of waste forms. Two investigations involving supercalcine have been performed and the results are recorded in this report. One experiment involves the interaction of supercalcine with groundwater while the second involves the interaction of a mixture of supercalcine plus basalt with groundwater. Both experiments have been carried out under the maximum conditions anticipated in the repository, namely 300/sup 0/C and 300 bars (30 MPa). Many unanswered questions remain, concerning the speciation of cations in solution, the full characterization of phases formed, and the prevailing Eh-pH conditions of reacted groundwater. Preliminary data have been obtained on the cations that were readily leached from unsintered supercalcine (SPC-4) and the general solubility properties of the groundwater buffered by SPC-4 +- basalt. In particular, it is observed that Si, Na, Mo, Rb, and Cr are readily leached from SPC-4 in the absence of basalt, and all of these except Cr are leached in the presence of basalt. Groundwater buffered by SPC-4 alone is thought to have in situ pH and Eh conditions of approx. 9.5 +- 0.5 and 0.0 to -0.4 V, respectively. Four secondarymore » phases have been identified with some degree of certainty: pollucite ((Cs,Na)AlSi/sub 2/O/sub 6/.xH/sub 2/O), ulvospinel (Fe/sub 2/TiO/sub 4/), ..cap alpha..-RuCl/sub 3/, and (Sr,Ca)MoO/sub 4/. Phases have not been identified to house the insoluble elements Zr, U, P, or Ba as well as the elements whose concentrations <0.2 wt % of the oxide. Finally, it is pointed out that further attention must be directed to the elements that have radionuclides of high biological danger, even if they do not seem dangerous from the aspect of their low thermal output.« less


The invention discloses a data distribution method and system for a network data center. The method comprises the following steps: at least one node server of the network data center downloading a source file from a data source server; a download management server storing the identification of a node server which already downloads the source file; a node server, which does not download the source file, of the network data center querying from the download management server the identification of the node server which already downloads the source file; and the node server which does not download the source file establishing download connection with a queried node server which already downloads the source file and downloading the source file from the node server which already downloads the source file. By using the method, some node servers in a network data center download a source file from a data source server, and other node servers download the source file from node servers which already download the source file so that it is unnecessary for all the node servers to download the source file from the data source server, thus occupation of special-line bandwidth of the network data center can be reduced.


In this paper, we have examined various implementations of matrix-matrix multiplication using .NET platform. Matrix multiplication is considered one of the basic operation in the field of linear algebra that is used various computer science algorithms. We have used the all loop reordering of traditional n3 sequential algorithm to analyze its behavior on the .NET common language run-time over more than 10 varying sizes of matrices. Moreover we have also analyzed the blocking version of the traditional multiplication algorithm to observe the cache behavior. We have used Intel Corei5 Arandale 2.53 GHz and Haswell 3.30 GHz processors with dual channel RAM for our experiments. Our experiments show that KIJ and IKJ reordering have performed better than the rest of the loop reordering. Furthermore, blocking implementation of matrix multiplication have not been able to gain significantly on .NET platform. In future, we will utilize task parallel library included in .NET 4.5 to gauge the performance efficiency of linear algebraic operations.


For the manufacturing process of fiber composite parts, various physical phenomena affect the geometry as well as the mechanical and chemical properties of the structure. For development and design of manufacturing processes, thermo-mechanical simulations are used. Here a coupled calculation of heat transfer, mechanical stresses and strains and the curing process of the matrix system are implemented for the determination of process parameters. A consideration of the composite part and the process environment, mainly the tooling, is important to get comprehensive and reliable results.

In the article the situation with school educational materials on History in Russia at the beginning of the XX century is analyzed. Within the framework of two directions of national historical science, official protective and liberal, the interpretations of foreign policy in the pages of pre-revolutionary school textbooks are considered. Authors represented Russia as a powerful state, which was carrying on indefatigable struggle with foreign aggressors. The main idea of the textbooks was the acquisition of new territories and the defence of conquered ones.


Since 2006, mHealth has seen an expansion of its market share and users that showed the need to regulate it, or at least define it. As often happens, the first were the United States, in September 2013, submitting the Guidance for Industry and Food and Drug Administration Staff, which solves some problems of definition but leads to underregulation, that creates issues of websecurity related to self-care.


The paper presents the innovative process with possibility of predict the state of deformation and stresses in a two-stage metal forming process. In the first stage, regular surface roughness with arched outlines are embossed. In the second stage, these inequalities are flat burnished to obtain the required dimensions, roughness of the surface, and state of deformation and stresses in the surface layer of the workpiece. The process are considered as a geometrical and physical non-linear boundary and initial value problem, with unknown boundary conditions in the contact zone. The applications were developed in the Ansys/LS-Dyna system, which makes possible a complex time analysis of the states of displacements, strains and stresses, in the workpiece in the two-stage cold metal forming processes. Application of this method were showed for examples the modelling and the analysis of the regular asperities with arched outlines. In the simulations, the material as well as the geometrical parameters of surface asperities were changed. The simulation results were verified experimentally.


The emergence of Islamic organization groups outside Nahdlatul Ulama and Muhammadiyah in Jambon, Gemawang, Temanggung has an impact to society's religiosity. The religious activities of those Islamic groups tend to be radical and different with the existed other Islamic groups. NU as a representation of Islam Nusantara is known to be tolerant, moderate and accommodative to culture, tradition and all the differences. While radical Islam promotes againts religious traditions. This article aims at describing the NU's strategy in  stemming religious radicalism. The method used is qualitative descriptive and data is collected by interviews and field observations. The results of this study suggested that to counter radicalism, the NU branch in that region has built mechanism of massive and structured campaign, set da'wah materials using scientific approach, accompanied youth activities intensively. Such efforts become resposibility for all components of society in order to become a stronghold of the influence of radical Islamic ideology, especially among the younger generation. The indicator can be seen in the increasing quantity of students in non-formal and formal educational institutions in Jambon, which is quite significant. Besides, public awareness appears to be selective in choosing incoming Islamic teachings.


The dispersion characteristics of kraft pulp resins were studied by analyzing turbidity and Zeta potential of resin water system. The relation between resins depositing tendency and pH value were also investigated. It was found that with the rise of pH the concentration of colloidal resin increased and the particle size became larger too, which led to their lower stability and higher depositing possibility. Several pitch control agents, PEO, LS, CPAM and PAC, were evaluated in their performance of reducing resin deposits. All of them showed obvious control effects but different working mechanisms.


Despite the historical patina of much of the extant literature, most of the scholarship on the `Revolution in Military Affairs' (RMA) reflects a profoundly superficial and ahistorical understanding of the changing nature of warfare. To be sure, this literature is not lacking in historical detail and analogy — indeed, one of its defining characteristics is a selfconscious attempt to use history alternatively to `prove' the RMA thesis and to illuminate the transhistorical dynamics of radical change in the nature of war. But these historical references are almost exclusively to transformations in the nature of warfighting. The purpose of this article is to address the problem of ahistoricism by reconnecting changes in the nature of warfighting to both broader transformations in the social organization of warfare and deeper changes in the nature of war as an historically constructed social institution.


Road transportation plays a critical role as a means to commute between places. Ensuring quality in this service, therefore, is crucial. In this paper, we explore the service quality characteristics of intercity bus passenger transport and analyse the determinants of commuters' perceived service value in the European and Indian context. A structured questionnaire was administered face-to-face and captured the passengers' perception of service quality. Factor analysis and multiple linear regression were used to test the research hypotheses of the study. Empirical results demonstrate that timely service, women-friendliness, ticket price affordability and service to price satisfaction are common to passengers from Europe and India, and significantly impact commuters' perceived service value devised as overall satisfaction. In particular, external tangibles such as clean drinking water, clean bus stops are however significantly more important for passengers in Europe, while handling of luggage is a more appropriate tangible for passengers in the Indian context. Additional analysis suggests that technology also significantly impacts the overall satisfaction of passengers in both contexts. Several comparative results were discussed for their context similarities and differences.


SUMMARY Myrtus communis L. (Myrtaceae) is a typical shrub of the Mediterranean maquis which grows spontaneously in Sardinia. It is used in the drug, perfume and food industries. Intensive myrtle cultivation systems should be developed, in order to assure both a constant supply of good quality material for the liqueur industry and the preservation of natural myrtle populations. Cultivar selection is essential for the successful cultivation of this new aromatic crop and has been the main goal of our research. The main morphological and phenological characters of 16 cultivars selected for fruit and biomass production are presented here.


Finding out how atoms and electrons move. This is very difficult to calculate exactly as it requires solving the Schrödinger equation, but we can try simulating a system using some form of classical mechanics andNewton's laws of motion. The major objective is finding out how to use classical dynamics to simulate a quantum system accurately – a naïve implementation can miss tunnelling, zero-point energy and many other quantum effects. This is important to fundamental science for describing the world at a microscopic level, but also has profound realworld implications, such as modelling hydrogen storage and enzyme catalysis.


We have measured the non-equilibrium current noise in a ballistic one-dimensional wire which exhibits an additional conductance plateau at 0 . 7 × 2 e 2 /h . The Fano factor shows a clear reduction on the 0.7 structure, and eventually vanishes upon applying a strong parallel magnetic field. These results provide experimental evidence that the 0.7 structure is associated with two conduction channels which have different transmission probabilities


Radioactive materials although are very useful, they are one of the catastrophic sources of mass destruction if misused. These materials have a number of positive uses which makes them very essential in our modern society. Incidences such as the bombings of the US Embassies in East Africa, the September 11, and many others had formed a basis for international responsive actions to control illicit trafficking of Radioactive and Nuclear Materials. The aim of this work is to track the movements and subsequently uses of these materials. Tanzania is one of the countries where International Nuclear Safeguards protocols are fully operational and observed. In the efforts of control, a number of institutions have been mobilized nationally to the. While these control efforts are enforced, it is observed that several routes and different radioactive purported sources are imported to Tanzania. Although most of the motives of illegal trafficking intercepted have indication of radioactivity through marking and signs, there are cases where the material has been falsified. On the other hand, the motive behind appears to be not only for use but rather illegal dealings such as trading. This paper sites these incidences, their causes and influences on the control and proposes way forward.


The results of field studies and remote sensing data are used to describe some peculiar features of forming land surface and loose rocks processes as due to a combined action of sea tides and ice cover in the sea coastal zone ecosystem.


Foreign materials are intentionally placed into patients in the form of medical devices for replacing or repairing damaged portions of the body. Materials also enter the body unintentionally in the form of particulates and fibers, and can then have damaging effects, such as the formation of disease or even cancer. Such is the case for inhaled mineral dusts and asbestos fibers. The interaction between living tissue and a foreign material is, in both cases, governed by the type and state of the host tissue as well as by the physical and chemical properties of the material. Of major importance is the role of material surface properties in reactions occurring at the material-tissue interface. Both the chemical properties and the morphology (i.e., topography, texture, or roughness) of the surface are important. They may act independently or in synergy in producing biological responses to foreign materials. A major goal for future biomaterials research and development is to control biological responses by engineering the surface to carry out specific biological functions. This requires an understanding of the independent roles of chemical versus morphological properties of material surfaces. It is therefore important to be able to systematically and independently vary each of these properties, and to study how they affect biological responses. The latter applies also to materials that unintentionally enter the body. The aim of this thesis work was to develop and apply micro- and nano-fabrication methods to produce well-controlled surfaces and particulates on all biologically relevant size scales. The capabilities of photo- and electron beam lithography to produce systematically and independently varying morphological and chemical features over the size range of nanometers to microns has been demonstrated and critically evaluated. Some of these structures have been used in biological model experiments. The main emphasis has been the development of methodologies to
produce, characterize, and apply microfabricated samples for studying cellular interactions. Samples containing spatially patterned, 10 µm square areas of Ti, Al, and V metal films have shown bacterial ( S. epidermidis ) adhesion preferences for V regions. A second example is the production of free fibers of cross-section 0.1 x 0.5 µm and lengths of 10, 1, or 0.1 µm in gold, titanium, and silicon oxide. The phagocytic response of alveolar macrophages to 10 µm long fibers of titanium and silicon oxide indicate differences owing to differences in fiber material chemistry alone. In addition to these two examples, a variety of structures for potential future biological experiments have been produced. They include 1 - 10 µm features and patterns etched into bulk polymethylmethacrylate or titanium surfaces. The main impact of this work is that it demonstrates the needs and opportunities for microfabrication and nanofabrication in both biomaterials (medical implants and devices, etc.) and respirable fiber research and development. The efforts put forth here therefore form the basis for future applications of micro- and nanofabriaction to biomaterials as well as to various other fields of research.


Bacterial count has been done in the framework of the large project designated as " hydrology and hydrobiology of southern part of Caspian Sea in the depths of less than 10 m" in 4 successive seasons from 1999 to 2000. There were 10 sampling lines, which positioned perpendicular to seashore in Mazandaran and Golestan provinces. In every line, 5 stations were assigned and 12 samples were taken in every party and every line. The applied method was bacterial plate count with 5 dilutions 10 2 ,10 -3 ,10 -4 ,10 -5 ,10 -6 in nutrient agar prepared with seawater. Also warm blooded animal coliforms as representative organisms of pollution were detected. Khazarabad and Tonekabon coastline had the most abundance bacteria and coliforms in all stations, the sediment counts were more than the count of the water column. More bacterial count were seen in stations far from the shore. Although sludge drainage is low in cold seasons, oppositely more bacterial count were observed in stations near the shore in warm seasons and this phenomenon is in compliance with the data obtained from " sediment sorting " .


broadly inclusive of patients with mediastinal disease, including both patients with lung cancer and patients presenting with an isolated mediastinal mass or lymphadenopathy. Studies of the accuracy of EUS-FNA and EBUS-FNA among patients with lung cancer only have demonstrated it to be a highly accurate and safe test. We also included patients with (78) and without (60) enlarged mediastinal lymph nodes ( 1-cm short axis). In both the overall group, as well as the group of patients without mediastinal lymph node enlargement, we found that using both EUS-FNA and EBUS-FNA was superior to any single procedure and EBUSFNA alone was superior to TBNA alone. Although we did not specifically evaluate patients with particularly bulky subcarinal lymph nodes, these nodes are easily and reliably sampled with TBNA. Finally, I agree that a trial directly comparing EUS-FNA and EBUS-FNA with mediastinoscopy in a non–small cell lung cancer population is warranted.


Polycyclic aromatic hydrocarbons (PAHs) in six samples from Bulgarian Lignite Dumps Maritsa Iztok are tracked and amounts are determined. For isolation of soluble organic matter (SOM) ca: 40 g of powdered dump samples were Soxhlet extracted by chloroform. After asphaltenes precipitation, maltenes were separated via column chromatography. The first two fractions were further analyzed. Gas chromatography-mass spectrometry (GC-MS) was applied to appreciate organic matter sources and to identify and quantify PAHs in the samples. The set of PAHs determined pointed out that 3 and 4 ring unsubstituted PAHs as dominant in the dump extracts. Total organic carbon (TOC) values of the samples varied in the range 1.18-5.63 wt.%. Phenanthrene + Methylphenanthrene amounts were in the range 0.44-2.98 mg/kg TOC, while for Fluoranthene + Pyrene were in the range 0.06-0.52 mg/kg TOC. Total amounts of PAHs varied in the range 7-41 microg/kg sample. Values were compared with the legislation norms for PAHs in soils. All magnitudes were under the regulation norms for harmful substances in soil published by the Bulgarian National Legislation (2008). In conclusion, the study is in an equivocal proof for the negligible amounts of PAHs in dump materials from Maritsa Iztok lignite mining. However, their amounts in dumps should be measured and monitored bearing in mind the huge territories covered by these waste materials of mining industry.


The aim of the present study was to monitor clinical, microbiological, medical, and immunological effects of non-surgical periodontal therapy in diabetics and healthy controls. 20 IDDM (insulin dependent, n = 7) or NIDDM (non-insulin dependent, n = 13) diabetic patients (median duration 11.5 years, range of HbA1C: 4.4-10.6%) with moderate to advanced periodontal disease and 20 matched healthy control patients, were subjected to supragingival pretreatment and subsequent subgingival therapy. Periodontal examinations (API, PBI, BOP, PPD, PAL), microbiological examinations (culture), medical routine examinations, and immunological examinations (oxidative burst response of PMNs to TNF-alpha and FMLP) were performed at baseline, 2 weeks after supragingival, and 4 months after subgingival therapy. 4 months after completion of non-surgical therapy, the following compared to baseline significant (p < or = 0.05) changes (delta) of clinical parameters (median) were found in diabetic patients versus control patients: deltaAPI (30.4% versus 36.3%), deltaPBI (22.9% versus 24.2%), deltaBOP (39.5% versus 46.9%). The median % per patient of pockets with PPD > or = 4 mm decreased from 41.9% to 28.3% in diabetics, and from 41.6% to 31.8% in controls. Microbiologically, similar reductions of periopathogenic bacteria were found in diabetics and controls. Neither periodontal data nor the oxidative burst response of PMNs showed any significant difference (p > 0.05) between diabetics and control patients. In this study, periodontal therapy had no significant influence on medical data of diabetics. In conclusion, this study indicates that metabolically well-controlled diabetics might respond to non-surgical periodontal therapy as well as healthy control patients.


An in situ carbon-13 NMR study of the kinetics and mechanism of the functionalization of poly(methyl acrylate) (PMA) by reactions with various amines is described. While the reaction with n-hexylamine (HAN) in a binary solvent of DMSO/o-dichlorobenzene (1:1, w/w) shows an autoacceleration effect, that with cyclohexanemethylamine (CN) exhibits autoretardation. The former is attributed to interactions that result in preferential solvation of nonpolar regions within the polymer domain, while the latter reflects the overwhelming effects of steric hindrance. Interestingly, while the presence of a single neighboring benzylamide group retards the reaction of benzylamine (BZA) with a PMA ester group, attack at an ester group flanked by benzylamide groups on either side is autoaccelerated


The article describes network structures as a kind of organizational structures in the modern economy.

THE GLOBAL NATURE of contemporary business adds a new dimension to the search for innovation. Competition can emerge from unforeseen quarters, so a company must be sure that new product development is both efficient and generating desirable results. Based on an extensive survey, Ranganath Nayak compares concerns regarding innovation in the US, Japanese, and European markets, and elaborates on specific elements that interfere with the innovation process.


The stability and unsteady behavior of journal bearings is much influenced by bearing geometry, and various designs have been used by engineers to promote stable bearing performance. The complexity of many of the bearing shapes used precludes anything other than purely numerical modelling if detailed quantitative results are sought for particular bearings. Much qualitative information on the general effect of bearing design is, however, obtainable from simple mathematical models in which the dominant physical effects of the geometry are retained. We describe such a model, in which the effects on design features on the dynamics of the bearing can be exposed and understood in analytic terms. In particular, we display the effects on whirl instability of bearing shapes which influence cavitation of the lubricant, and propose that it is though the control of cavitation that bearing geometry exerts crucial effects. Presented at the 40th Annual Meeting in Las Vegas, Nevada May 6–9, 1985


Book Review: Cultivating Environmental Justice: A Literary History of U.S. Garden Writing by Robert S. Emmett, Amherst and Boston, University of Massachusetts Press, 2016, vii + 231 pp., UK £24.00 (paperback) ISBN 978-1-62534-205-8


Some future historian of the development of scientific hydrology will probably be tempted to call the present period the "era of infiltration." At any rate, the preoccupation of contemporary hydrologists with "the infiltration theory of runoff," and the vast amount of energy they have expended in an effort to turn this concept to practical account, will certainly be put down as a distinctive feature of our times

There have, of course, been logical reasons for this remarkable interest in the subject. As in all sciences, many have been attracted to it simply because of its newness. Another class—and the one that has participated most eagerly—is composed of those intrepid practicing engineers who are obliged to make the runoff estimates upon which depend the failure or success of costly flood control, water supply, and similar works. Still another group has been intrigued by a purely scientific interest, sharpened by the fact that the calculation of runoff is the central problem of the science of hydrology and involves all phases of the hydrologic cycle. Among these are scientists in the fields of soils, plants, and meteorology. As a result of these various motivations, vast amounts of labor have been expended—much of it misdirected—and many exaggerated claims have been made, to be countered, naturally, by the disparaging murmurs of the "old guard," and other important lines of investigation have been temporarily slighted. But real progress has been made. Better estimates of runoff are now possible than could be made previously. Problems that would not yield at all to earlier methods are now soluble, albeit the solutions are sometimes only rough approximations. The inescapable conclusion is that a tool of considerable practical value has been added to the equipment of the hydrologist.


The He I and He II photoelectron spectra of CF2Br2, CF2BrCl, CBr2Cl2, and CFBr3 have been recorded under low and high resolution. The assignment is based on correlation with assignments for other halogenated methanes, on He II/He I intensity comparisons, and on the vibrational fine structure observed in some systems.


The implementation of the Party's policies on education in education practice requires the whole society to make a more complete and deeper understanding of the importance of art education and it is also a longtime task for those who are engaged in arts education to promote arts education.


In the present study, wind conditions were numerically predicted for the site of the Bolund hill using the RIAM-COMPACT natural terrain version software, which is based on an LES turbulence model (CFD). In addition, airflow measurements were made using a split-fiber probe in the boundary layer wind tunnel. The characteristics of the airflow at and in the vicinity of the site of the Bolund Experiment were clarified. The study also examined the prediction accuracy of the LES turbulence simulations (CFD). The values of the streamwise (x) wind velocity predicted by the CFD model were generally in good agreement with those from the wind tunnel experiment at all points and heights examined, demonstrating the validity of CFD based on LES turbulence modeling.


The photodegradation of 2,4-dichlorophenoxyacetic acid (2,4-D) taking place in UV irradiated aqueous TiO2 dispersions was revisited to obtain mechanistic details on the basis of similar degradation of the related 2,3-dichlorophenoxyacetic acid (2,3-D), 4-chlorophenoxyacetic acid (4-M) and phenoxyacetic acid (PhA). Mechanistic changes were inferred from the different positions of the chlorine substituents. As well, the compounds were compared for differences in degradation rate and initial adsorption on the TiO2 surface as a function of the number of chlorines. The initial mechanistic sequence(s) in the TiO2-photocatalyzed oxidation of each substrate was predicted theoretically by molecular orbital (MO) calculations of frontier electron densities and point charges of all the atoms in the phenoxyacetic acid structures.


The results of a transmission electron microscope study of the hydrothermal alteration products formed by perovskite and two titantate-based "synroc" formulations are reported. It was found that perovskite, the host phase for strontium-90, dissolved at combined temperatures and pressures greater than 110°C and 180 kPa. Dissolution of perovskite was accompanied by an epitaxial crystallization of the titanium dioxide polymorphs, brookite and anatase. Hollandite, which incorporates cesium-137, dissolved more slowly than perovskite, with only minor TiO2 crystallization. Intergrowths of zirconolite and zirkelite, the principal actinide-containing phases, were highly resistant to hydrothermal treatments, maintaining their integrity under all experimental conditions.


Abstract— The effect of the selective A1 adenosine antagonist, 8‐cyclopentyl‐1,3‐dipropylxanthine (CPX), on Escherichia coli endotoxin‐induced acute renal dysfunction was determined in anaesthetized rats. Bolus administration of endotoxin at doses of either 1 or 20 mg kg−1 evoked decreases in inulin clearance, renal blood flow, urine flow and excretion of sodium, potassium and chloride. The changes in renal function produced by 20 mg kg−1 endotoxin were more severe than those noted with 1 mg kg−1 toxin and, by contrast to this lower dose, renal function showed no signs of recovery. Intravenous administration of CPX (0·1 mg kg−1) elicited a statistically significant, although modest, attenuation of the decline in inulin clearance, renal blood flow, urine output and electrolyte excretion induced by 20 mg kg−1 endotoxin. By contrast, treatment with 0·1 mg kg−1 CPX resulted in statistically significant protection against the falls in excretory function evoked by 1 mg kg−1 endotoxin but not against the reductions in renal blood flow and inulin clearance produced by the lower dose of toxin. These results suggest that adenosine may play a role, albeit not a major one, in the pathophysiology of endotoxaemic acute renal failure.


The United States Government has announced that the next plant to be built in this country for the enrichment of U-235 will be a gas centrifuge plant rather than a gaseous diffusion plant. The important aspects of the theory of isotope separation for these two processes are reviewed and the differences between them are delineated. The advantages and disadvantages of the centrifuge process are enumerated.


Trichosanthes kirilowii peel were used to extract polysaccharides by microwave-assisted extraction.The optimum microwave-assisted extraction conditions were obtained through response surface analysis.The antioxidant activity of Trichosanthes kirilowii peel polysaccharides was evaluated by total reducing power,hydroxyl radical scavenging assay and NO2-scavenging assay.The results showed that the optimal extraction conditions were as followed:the material-to-liquid ratio was 1∶40,the extraction time was 15min,and the microwave power was 450W.Under these extraction conditions, the rate of polysaccharides yield were 2.52%.When its solution concentration was 1.2g/L,the reducing power,the hydroxyl radical scavenging rate and the NO2-scavenging rate of the polysaccharides were 0.54(OD),72.8% and 35.6% respectively.Trichosanthes kirilowii peel polysaccharide was a kind of natural antioxidant.


Purpose: Multiple studies have documented that high resting levels of cardiac vagal tone suggest higher levels of selfregulation. The aim of this study was to evaluate cardiac vagal tone as an indicator of autonomic nervous function in healthy newborn and premature infants. Methods: This study was conducted using a descriptive comparison design and a convenience sampling strategy. The participants were 72 healthy and 62 premature infants delivered in a university hospital. Continuous heart rate data recordings from the infant's ECG were analyzed and Mxedit software was used to calculate mean heart period and an index of cardiac vagal tone. Results: The healthy infants had significantly higher cardiac vagal tone than the premature infants, when the influence of gestational age was removed using analysis of covariance. However, there were no significant differences in heart rate and heart period between the two groups when the influence of gestational age was removed using analysis of covariance. Conclusion: The results of this study show that cardiac vagal tone may be used as an index for determining infant's autonomic nervous function. Nursing staff in pediatric departments can use cardiac vagal tone with ease, as this index can be calculated in a noninvasive method from the ECG.


Background and aims Pulsed radiofrequency (PRF) has been shown in structural studies to selectively impact small-diameter fibers. Herein, we demonstrate that PRF attenuates function hosted by small-diameter axons while preserving function of large-diameter fibers, and these effects were coincident with structural changes. Methods Fifteen Sprague-Dawley rats were anesthetized. Animals were randomly assigned to PRF (20ms,2Hz,120s,42°C,55–75V) or sham (120s, no PRF) groups after placement of a radiofrequency probe tip-down on the sciatic nerve (≤0.5 V threshold). the Nociceptive Flexion Reflex (NFR) was elicited by stimulation on the foot (8 ms,20–80 V) and motor function was assessed by proximal sciatic-nerve stimulation (50 μs,5–30 V). the average electromyogram (EMG) area corresponding with the NFR (latency: 150–650 ms; small-diameter unmyelinated-fibers) and motor function (latency: 1–10 ms; large-diameter myelinated fibers) was recorded before and after treatment. Welch's t-tests were performed with Bonferroni correction. Nerves were preserved and assessed by a third-party histologist (H&E or electron microscopy). Results PRF reduced the NFR and motor responses by a between-animal average of 70.0% and 12.4%, respectively, while sham treatment reduced these by 10.4% and 2.0%, respectively (figure 1a). Significant differences were observed for the NFR in PRF-treated animals vs. sham animals (p < 0.0001) and between the NFR and motor response in PRF-treated animals (p < 0.0001). No detectable nerve damage was observed via light microscopy (n=3). Electron microscopy (n=3) suggested preferential disruption to mitochondria of small-diameter fibers (figure 1b). Abstract ESRA19-0424 Figure 1 Conclusions PRF selectively attenuates the NFR while sparing motor conduction. Disruption of subcellular structures is one of many possible explanations for the selectivity of PRF.


Infrared (IR) heaters are used in many industries where heat treatment is required as well as in household appliances. One of the main problems with this type of equipment is non-uniform temperature field in the heating area, which results in a different degree of heating of the heated objects. In order to achieve greater uniformity of the temperature, some approaches are explored in practice, such as using embossed reflectors, mounting two or more heaters side-by-side, using emitter lamps with power controller devices, formation of gold or silver coatings, etc. The drawbacks of these approaches are complicating the design of the IR heaters, reducing the dimensions of heating area, increasing energy consumption, etc. Among the above-mentioned methods, the creation of a specific reflector surface topography is easily attainable and inexpensive technological approach. The main task of the present study is to investigate experimentally the influence of the specific patterns, obtained by ball burnishing process on scattering ability of the aluminium reflectors from infrared quartz heater.


Waveform-resolved, bathymetric lidar applications demand high performance analog-to-digital converters (ADCs) to meet the demands of the high bandwidth, large dynamic range signals which are typical for coastal mapping applications. In this paper, the Agilent M9703A digitizer is evaluated with this criteria in mind and found to be an excellent candidate. Furthermore, the customizable FPGA firmware onboard the M9703A has been used along with a GPU to demonstrate the real-time computation of a lidar coordinate point cloud - significantly reducing the computation time required for current state-of-the-art systems from hours to seconds.


The distribution function of relaxation times in disordered dielectrics has been calculated in the random field theory framework. For this purpose, we first consider the dynamics of single two-orientable impurity electric dipole in a random electric field E created by the rest of impurities in disordered ferroelectric. This dynamics is conveniently described by Langevin equation. Relaxation time τ is then a reciprocal probability (calculated on the base of Fokker-Planck equation) of the dipole transition through barrier in a double-well potential (corresponding to two possible dipole orientations), distorted by a random fields. The obtained dependence τ ( E ) made it possible to obtain the expression for relaxation times distribution function F ( τ )(via random fields distribution function f ( E ). Latter function has been calculated self-consistently in the random field theory framework. Nonlinear random field contribution and effects of spatial correlations between impurities have also been taken into account. It was shown that nonlinear contribution of random field gives asymmetric shape of F ( τ ), while in linear case it is symmetric. Comparison of calculated F ( τ ) curves with those extracted from empirical Cole-Cole (CC), Davidson-Cole (DC), Kohlrausch-William-Watts (KWW) and Havriliak-Negami (HN) functions had shown, that they correspond to mixed ferro-glass phase with coexistence of short and long-range order. Different forms of F ( τ ) are determined by linear (CC) or nonlinear (DC, KWW, HN) con-tributions of random field.


2D speckle tracking echocardiography (STE) atrial strain (ε) analysis in children is gaining interest; however, pediatric nomograms remain limited. Comparison among conventional software's (designed for left ventricle and adapted to atria and using R‐gating analysis) and new software's (designed for atria and allowing for both R‐ and P‐gating) are lacking. The present study aims to establish pediatric nomograms for atrial ε using an atrial dedicated software and to compare values obtained by (a) R‐ and P‐gating and, (b) R‐gating with new and conventional software.


Slip-pathway activation provides plasticity in a multiprincipal element alloy with high-temperature strength Although conventional alloys are based mainly on one element, recent design efforts have focused on multiprincipal element alloys (MPEAs) that contain substantial quantities of several elements. Success with this approach requires a robust understanding of the mechanistic origin of MPEA properties. On page 95 of this issue, Wang et al. (1) report the deformation behavior in a promising body-centered cubic (bcc) MPEA with good room-temperature plasticity and high strength at the temperatures at which conventional alloys would soften. They observed multiplanar, multicharacter dislocation slip that was not expected in bcc systems. This property is attributed to variations in the glide resistance along the core of dislocations, created by the atomic-scale fluctuations in composition that are characteristic of MPEAs. This mechanism explains the plasticity and could be used to guide the design of new MPEA candidates for high-temperature applications in aerospace and power generation.


This study is aimed at describing proverbs from the Acehnese society and explaining the attitudes of people towards those proverbs in relation to education. The methodology applied was ethnographic using a questionnaire to obtain data. A number of 14 respondents who varied across ages, educational background and occupations participated in this study. These respondents included three housewives, two university students, one fresh graduate, one junior high school and two senior high school students, one trader, two senior citizens, one teacher and one civil servant. Based on the findings, the attitude nowadays of the Acehnese has changed radically. Out of eight adults, only three were actively using proverbs in their daily lives and teaching their children those proverbs. All of the young people, who ranged from fourteen to twenty three years old, did not use proverbs. In relation to education, proverbs are used to teach the society about courtesy, advices (e.g. for choosing companions and friends in life, child rearing, socializing/conversing, and not to mind other people's business), and shyness as part of faith. Furthermore, a significant language shift has occurred in Aceh which has impacted Acehnese oral literature whereby more parents today prefer Indonesian to be taught as their children's first language (Alamsyah, et al., 2011). Consequently this has put the Acehnese proverbs under the threat of becoming extinct in their own society.


Butterflies use visual and chemical cues when interacting with their environment, but the role of hearing is poorly understood in these insects. Nymphalidae (brush‐footed) butterflies occur worldwide in almost all habitats and continents, and comprise more than 6,000 species. In many species a unique forewing structure—Vogel's organ—is thought to function as an ear. At present, however, there is little experimental evidence to support this hypothesis. We studied the functional organization of Vogel's organ in the common blue morpho butterfly, Morpho peleides, which represents the majority of Nymphalidae in that it is diurnal and does not produce sounds. Our results confirm that Vogel's organ possesses the morphological and physiological characteristics of a typical insect tympanal ear. The tympanum has an oval‐shaped outer membrane and a convex inner membrane. Associated with the inner surface of the tympanum are three chordotonal organs, each containing 10–20 scolopidia. Extracellular recordings from the auditory nerve show that Vogel's organ is most sensitive to sounds between 2‐4 kHz at median thresholds of 58 dB SPL. Most butterfly species that possess Vogel's organ are diurnal, and mute, so bat detection and conspecific communication can be ruled out as roles for hearing. We hypothesize that Vogel's organs in butterflies such as M. peleides have evolved to detect flight sounds of predatory birds. The evolution and taxonomic distribution of butterfly hearing organs are discussed. J. Comp. Neurol. 508:677–686, 2008. © 2008 Wiley‐Liss, Inc.


R. SLEIDERINK, « Une si belle histoire de nos propres seigneurs. » The nobility of Brabant
and literature in Dutch (first half of the 14th Century)
To what extent did the aristocracy of Brabant contribute to the blossoming of literature in Dutch during the first half of the 14th Century ? In an attempt to answer this
question, the article first of all examines the form and content of some 50 manuscripts
(the list of which is provided in an annex) written in the Duchy during that period.
Moreover, new texts were being composed in Brabant at that time. The circumstances
of their drafting demonstrate that from then on all strata of the nobility in Brabant
regarded Dutch as a literary language. Dutch literature was actively encouraged
by the bourgeoisie, but also by aristocratic circles. Because of the Duchy's growing
political isolation, the influence of French literature declined while interest for local
history was aroused.


In the following article ( DOI 10.1163/1569206x-00001670), I situate Daniel Bensaid's 'Strategy and Politics' within the different phases of his thinking about strategy as well as his own general theoretical background that informs parts of the text.


Tropifexor, a non–bile acid farnesoid X receptor (FXR) agonist, has dose‐proportional pharmacokinetics and no obvious major enterohepatic circulation. This open‐label study investigated the effect of hepatic impairment (HI), as determined by Child‐Pugh grade, on tropifexor's pharmacokinetics, safety, and tolerability following a 200‐μg dose in the fasted state. Blood samples were collected through 168 hours after dosing for quantification and plasma protein‐binding determination. Total tropifexor exposure was comparable across participants with HI vs those with normal hepatic function. Tropifexor was highly protein bound (>99%) in human plasma across participants of all groups. The average unbound fractions (percentage free) were 0.14% in participants with normal hepatic function and mild HI, which increased to 0.17% and 0.24% in participants with moderate and severe HI, respectively. Similar unbound drug exposure was noted in participants with mild HI and normal hepatic function. Participants with moderate HI (N = 8) had a 1.6‐fold increase in unbound exposure (area under the plasma concentration–time curve from time 0 to infinity [AUCinf,u]) and a 1.3‐fold increase in maximal exposure (Cmax,u) vs those with normal hepatic function (geometric mean ratio: AUCinf,u, 1.64 [90%CI, 1.25‐2.16]; Cmax,u, 1.30 [90%CI, 0.96‐1.76]). Participants with severe HI (N = 8) had a 1.6‐fold increase in AUCinf,u (1.61 [90%CI, 1.04‐2.49]) and comparable Cmax,u (1.02 [90%CI, 0.60‐1.72]) compared to participants with normal hepatic function. Tropifexor was well tolerated. The relative insensitivity of tropifexor to HI offers the potential to treat patients with severe liver disease without dose adjustment.


ABSTRACT In response to activation of the Wnt signaling pathway, β-catenin accumulates in the nucleus, where it cooperates with LEF/TCF (for lymphoid enhancer factor and T-cell factor) transcription factors to activate gene expression. The mechanisms by which β-catenin undergoes this shift in location and participates in activation of gene transcription are unknown. We demonstrate here that β-catenin can be imported into the nucleus independently of LEF/TCF binding, and it may also be exported from nuclei. We have introduced a small deletion within β-catenin (Δ19) that disrupts binding to LEF-1, E-cadherin, and APC but not axin. This Δ19 β-catenin mutant localizes to the nucleus because it may not be efficiently sequestered in the cytoplasm. The nuclear localization of Δ19 definitively demonstrates that the mechanisms by which β-catenin localizes in the nucleus are completely independent of LEF/TCF factors. β-Catenin and LEF-1 complexes can activate reporter gene expression in a transformed T-lymphocyte cell line (Jurkat) but not in normal T lymphocytes, even though both factors are nuclear. Thus, localization of both factors to the nucleus is not sufficient for activation of gene expression. Excess β-catenin can squelch reporter gene activation by LEF-1–β-catenin complexes but not activation by the transcription factor VP16. Taken together, these data suggest that a third component is necessary for gene activation and that this third component may vary with cell type.


Aorto‐iliac arterial occlusive disease is common and may cause a spectrum of chronic symptoms from intermittent claudication to critical limb ischemia. Treatment is indicated for symptoms that have failed lifestyle and medical therapies or occasionally to facilitate other interventional procedures such as TAVR and/or placement of hemodynamic assist devices. It is widely accepted that TASC A, B, and C lesions are best managed with endovascular intervention. In experienced hands, most TASC D lesions may be treated by endovascular methods, and with the development of chronic total occlusion devices, many aorto‐iliac occlusions may be recanalized safely by endovascular means. Interventional cardiologists should be well versed in the anatomy, as well as the treatment of aorto‐iliac disease, given their need to traverse these vessels during transfemoral procedures. Overall, aorto‐iliac occlusive disease is more commonly being treated with an endovascular‐first approach, using open surgery as a secondary option. This document was developed to guide physicians in the clinical decision‐making related to the contemporary application of endovascular intervention among patients with aorto‐iliac arterial disease. © 2014 Wiley Periodicals, Inc.


This paper tried to systematize some physical-chemical properties of four vegetable oils samples and one tallow sample, aiming ultimately to establish behavior patterns in flotation systems. The flowing vegetable oils were studied: refined rice, castor, grape seed and soy oil. These oils are usually employed in mineral technology operations, with emphasis on froth flotation systems. The densities were determined: 930 kg/m³ for grape seed oil; 950 kg/m³ to castor oil; 910 kg/m³ to refined rice bran oil, and 920 kg/m³ for soybean oil. As to surface tension is concerned 26 tests were performed for each sample of vegetable oil and the values ranging from 0.0322 N/m to 0.0334 N/m. Apparent dynamic viscosity, surface tension and refractive indices were also surveyed. The results allowed us to know the samples' features and compare them with those showed in the literature, thus serving as a subsidy to the understanding of the influence of these properties on flotation systems.


This letter deals with the problem of detecting DoS and DDoS attacks. First of all, two features including number of packets and number of source IP addresses are extracted from network traffics as detection metrics in every minute. Hence, a time series based on the number of packets is built and normalized using a Box-Cox transformation. An ARIMA model is also employed to predict the number of packets in every following minute. Then, the chaotic behavior of prediction error time series is examined by computing the maximum Lyapunov exponent. The local Lyapunov exponent is also calculated as a suitable indicator for chaotic and nonchaotic errors. Finally, a set of rules are proposed based on repeatability of chaotic behavior and enormous growth in the ratio of number of packets to number of source IP addresses during attack times to classify normal and attack traffics from each other. Simulation results show that the proposed algorithm can accurately classify 99.5% of traffic states.

Based on the mechanism of free radical polymerization,ammonium persulfate,sodium sulfite and pentaerythritol as redox initiation system,the high molecular weight star-polyacrylamide was synthesized and characterized by 1H NMR.The limiting viscosity number and the rate of turbidity removal of star-polyacrylamide were affected by a variety of factors such as proportion of initiator and amount,initiation system and temperature,monomer concentration and amount of EDTA and urea.The effect of dosage of star-polyacrylamide on the rate of turbidity removal and the comparison of the rate of turbidity removal between star-polyacrylamide and liner-polyacrylamide were analyzed.The results showed that the complex polyacrylamide is the star-polyacrylamide and the average arm number is 3.2.When the doage is 2 mg/L,the rate of turbidity removal of clay suspension is up to 88%.The rate of turbidity removal of star-polyacrylamide is higher than liner-polyacrylamide that has the same limiting viscosity number with star-polyacrylamide.


Between the 1890s and the 1920s, mass consumer culture and modernism grew up together, by most accounts as mutual antagonists. This provocative work of cultural history tells a different story. By delving deeply into the publishing and promotional practices of the modernists in Britain and America, however, Mark Morrisson reveals that their engagements with the commercial mass market were in fact extensive and diverse. The phenomenal successes of new advertising agencies and mass market publishers did elicit what Morrisson calls a "crisis of publicity" for some modernists and for many concerned citizens in both countries. But, as Morrisson demonstrates, the vast influence of these industries on consumers also had a profound and largely overlooked effect upon many modernist authors, artists, and others. By exploring the publicity and audience reception of several of the most important modernist magazines of the period, "The Public Face of Modernism" shows how modernists, far from lamenting the destruction of meaningful art and public culture by the new mass market, actually displayed optimism about the power of mass-market technologies and strategies to transform and rejuvenate contemporary culture and, above all, to restore a public function to art. This reconstruction of the "public face of modernism" offers surprising new perceptions about the class, gender, racial, and even generational tensions within the public culture of the early part of the century, and provides a rare insight into the actual audiences for modernist magazines of the period. Moreover, in new readings of works by James Joyce, George Bernard Shaw, Wyndham Lewis, Ford Madox Ford, T. S. Eliot, William Carlos Williams, and many others, Morrisson shows that these contexts also had an impact on the techniques and concerns of the literature itself."

Purpose – This paper is an empirical study of the organisational approaches used for integration of management systems (MSs) and the comparative effectiveness of such approaches.Design/methodology/approach – Research employed four case studies. Results are derived from the analysis of triangulated evidence obtained from in‐depth interviews, observations, internal documents analysis, archives, and short questionnaires.Findings – Results identified two archetypes of integration strategies termed "systems approach" and "techno‐centric approach". Maximum benefits are achieved by using a systems approach to integration of MSs, while using the techno‐centric approach leads to benefits mainly at the operational level.Research limitations/implications – This research is qualitative and, as such, does not investigate the integration of MSs across a large number of organisations. The research does not investigate the causality between strategies employed for integration and their outcomes.Originality/value – There ...


The invention relates to a transport pipe for thick matter, especially for concrete. The transport tube consists essentially of a pressure tube (16) and cohesively fixed to at least one end side on the outer surface of the pressure tube (16) coupling ring (18 ', 18' '). According to the invention the coupling ring (18 ', 18' ') has a ring part (34) having a relation to the diameter of the outer surface of the pressure tube (16) excess having inner surface and two, the ring part at its axial ends delimiting projecting with a radial component inwards, with its tip (44) against the outer surface of the pressure tube (16) circumferentially adjacent supporting lips (36, 38). The coupling ring (18 ', 18' ') bounded by the inner surface of its annular section (34) together with the supporting lips (36, 38) and the outer surface of the pressure tube (16) an annular gap (40) at least partially with adhesive (50 ) is filled for the production of the material connection.


Haemaccel is a new plasma substitute, a dissolved polymer of decomposed, highly purified gelatine. The preparation has an average molecular weight of approximately 35,000 divided into a high-molecular and a low-molecular portion. The colloid solution contains the same amino acids as gelatine, but chemically and especially structurally it differs greatly from the original material. The solution' is clear, yellowish and can be sterilized. The colloid osmotic pressure of a 3% Haemaccel solution is the same as that of plasma. A 3.574 solution of Haemaccel is slightly hypertonic, whereby the backflow of water from the tissues to the vessels is facilitated. The viscosity is the same as that of human plasma. Haemaccel is sterile, pyrogen-free and contains no preservatives. In a clinical study, 500 ml Haemaccel was given prophylactically to 50 patients subjected to general surgery. The value of Haemaccel as a plasma expander was estimated by the change in haemoglobin, haematocrit and the erythrocyte count immediately before and after the infusions. Table 1 shows the changes in erythrocyte counts.


A new laser optical measurement technique for the determination of concentrations within liquid/liquid systems - rainbow refractometry - is being introduced. Beside giving an overview of the physical background and the principle of measurement the options of determination of homogeneous equilibrium concentrations within droplets by measuring the position of the primary monochromatic rainbow are explained experimentallly for the system toluene/water/acetone. For the investigation of the effect of concentration gradients induced by instationary mass transfer processes a coupled model of diffusion and refractive index gradient for the rainbow is introduced. Data simulated by this model are being compared to experimentally obtained values and discussed briefly. It is obvious that the slope of the rainbow position can give information about concentration gradients.

The growth of plant is modeled by Open L-system, and the Octree and Ray-trace methods are used to model the light environment, and the dynamic Plant-Light interaction is also simulated. Furthermore, the phototropism phenomenon in plant growth is presented.


Business applications rely typically on databases for storing and processing their data (database-driven applications, or DBAPs). Testing DBAPs requires testing the application logic plus the interaction between the application logic and the database. Thus, DBAP test cases consist of input and output parameter values, the function to be tested, and an initial database state (i.e., DBAP test data). Various test data provisioning methods exist, such as manual test data design, generators for synthetic test data, and live-system snapshots. Many criteria and factors influence which method is optimal for a given project setting, such as costs, quality, data privacy, etc. This paper presents our methodology for guiding software development projects towards the DBAP test data provisioning method best suited for them.


The ability of heat inflation of various starch paste which were gelatinized at 100°C in highly concentrated starch suspension by plastograph and dried at room temperature were studied. The effects of gelatinization temperature upon the volume of heat inflation of starch were also tested. 1) The largest heat inflation of starch paste was potato starch; 7.7 times of initial volume. It was followed by tapioca, sago, waxy corn, sweet potato, rice, corn and wheat starch in the order of larger inflation. The order of heat inflation was similar to that of peak viscosity in amylogram, not in plastogram. 2) Next, the volume of heat inflation of starch paste gelatinized at various temperature was examined. Potato starch had two peaks of inflation volume at 70°C and 90°C of gelatinized temperature, however, every other kind of starch had only one peak, such as sweet potato at 90°, waxy corn at 95°, and corn starch at 100°C respectively.


Milinda-pa¤ha is an important sutra which records the questions and answers concerning Buddhist dogmas between Milinda the king of Sāgala descended from Greece and Nagasena the monk come from Central India.In the sutra there are two Greek factors,namely the Platonic questioning and the discussion of idea or form.And there are much more Chinese factors in it such as filial piety,a conception typically of Chinese ethics which has been carefully discussed.In addition to this,there are five sayings from Confucian classics such as the Analects,Mencius and the Book of Rites,"It passes this way!" "The superior is wise and the inferior is foolish." "You learn,and then you know." "A great Soup is without any condiment." "It is of no help to dig a well when one is thirsty." There are two sayings from Laozi and Zhuangzi,"One satisfied with the times will live smoothly." "Content brings wealth." There is one saying from the Zuo Commentary,"One must keep his word at the critical juncture." The literal meaning of Nagasena is very clear,but there have appeared many conjectures on it,some available from the sutra,and some visible in documents of later ages.The tone of the Chinese version is distinct from those translations made by monks from India and the Western Regions.It is reasonable to infer that the translator of the Chinese version of Milinda-pa¤ha is a Chinese scholar of Confucianism.


Voltage stability in power systems is influenced by generator field-, and armature current limiters, on-load tap changers and load dynamics. This dissertation analyses possible interactions between these system components by computer simulations of long-term power system dynamics. The different modes of generator current limiter operation are analysed and it is shown that possible transitions between these modes can cause voltage instability. The importance of the armature current limiter behaviour is emphasized since this protection system causes the generator to lose all of its voltage support when trying to keep the armature current on a constant level. During a voltage decline in the transmission network, the on-load tap changers try to maintain a constant load voltage. This will cause a higher current demand in the transmission system which increases the voltage drop even more. It is shown how dynamic load characteristics can have a strong influence on the outcome of a disturbance. A load recovery in combination with on-load tap changers may cause an overshoot in power demand leading to a higher stress on the system compared to a constant power load. The system is also sensitive to the static load dependence where a small variation in characteristics may cause a completely different outcome of a disturbance. The phenomena mentioned were studied in a small power system with special attention to the current behaviour. That voltage stability can be treated as a 'current problem' is best shown by the on-load tap changer behaviour and the armature current limiter actions. These components have a strong influence on the currents in the system. A clear indication that the system sooner or later will approach voltage instability is therefore an increasing current combined with a decreasing voltage. This current versus voltage relation is briefly studied through the parameter ∆ I/ ∆ U.


There is increasing interest in the evaluation and treatment of patent foramen ovale, which has been associated with various pathologic conditions, such as cryptogenic stroke, platypnea–orthodeoxia syndrome and migraine. However, optimal treatment of patients with patent foramen ovale has not been established. This article aims to review the clinical manifestation and current therapeutic options for patent foramen ovale.


ry of American archaeology. It is exceptionally well researched, documented, and edited, and liberally stocked with maps and photographs. The photographs, along with quotes from correspondence, meeting programs, and transcripts from tape-recorded sessions, effectively impart the conference's personality and substance. Like the conference itself, however, some might view the book's detailed content as a weakness. Some too might question whether the author's role as an archaeologist, with an intimate and long-term association with the conference, can permit a critical appraisal of the various gatherings' purposes and achievements. Perhaps for personal reasons, but more probably because he never intended to do so, Woodbury has avoided a sustained theoretical critique of the Pecos Conference. He has chosen instead to chronicle its events precisely and in almost journalistic style, in order to "bring alive the Conferences, their many individual participants, the changing flow of research interests, and the issues and problems of the day" (pp. xxii-xxiii). Again, one's theoretical orientation and views regarding the proper scope of disciplinary histories (and who should write them) will determine whether this approach is seen as strength or weakness. It impressed me as a strength. With a detailed and personally informed mode of reporting, Woodbury has carefully and fairly laid the foundation for theoretical appraisals of the Pecos Conference in a way that no "outsider" could match.


BACKGROUND
Fungicides of the succinate dehydrogenase inhibitors (SDHI) group have been used in soybean to control Asian soybean rust (ASR) caused by Phakopsora pachyrhizi. Fungal populations with less sensitivity to SDHI fungicides have been reported since 2015.

RESULTS
In this study, fungal sensitivity to benzovindiflupyr (BZV) and fluxapyroxad (FXD) was assessed using a total of 770 P. pachyrhizi populations sampled over four soybean growing seasons. Cross-resistance, intrinsic activity, and frequency of SDHC-I86F mutation was also analyzed. The average EC50 and SDHC-I86F frequency increased over the 2015/2016, 2016/2017, 2017/2018 and 2018/2019 soybean-seasons. Fourteen P. pachyrhizi populations had the EC50 value above 10 mg L-1 for both carboxamides. No difference was found in intrinsic active to BZV and FXD fungicides for sensitive P. pachyrhizi populations. For P. pachyrhizi classified as less sensitive BZV showed the highest fungitoxicity effect. High frequency of the C-I86F mutation was observed in samples collected in volunteer soybean plants. The maximum frequency of SDHC-I86F mutation in the population was 50% and resulting in ASR populations with low sensitivity to SDHIs. A low correlation between bioassay and SDHC-I86F mutation was observed possible due to the dikaryotic nature of rust fungi or other mutations in the other SDH subunits.

CONCLUSION
The present work provides an overview of a large sampling size of P. pachyrhizi populations and their performance over the four crop seasons. The high frequency of SDHC-I86F mutation and low sensitivity to SDHIs are widely distributed in the main soybean growing regions in Brazil and present in volunteer plants in the soybean-free period. Further detailed studies are needed to identify novel point mutations affecting the effectiveness of SDHIs. This article is protected by copyright. All rights reserved.


The purpose of this study is to disclose the utilization of office hours from the perspective of faculty members and students. The sample consisted of (253) faculty members and (429) university students distributed among the University of Jordan, German Jordanian University, Arab Open University, and Al-Ahliyya Amman University. For the purpose of this study two questionnaires were administered for the faculty members and university students. The two questionnaires have enjoyed acceptable level of reliability and validity. The results of the study showed that the utilization of office hours from the perspective of faculty members and students was at the medium level. The results, also, showed that the academic rank and type of university (public or private) were factors influencing the utilization of office hours.


Although positive metacognitive beliefs have been found to be associated with symptoms of depression and generalised anxiety disorder, surprisingly few studies have focused on the degree to which positive metacognitive beliefs are associated to social phobia symptoms. In response to this limitation, the primary goal of the current study was the development and validation of the Positive Beliefs about Post-Event Processing Questionnaire (PB-PEPQ). It was anticipated that the PB-PEPQ would exhibit adequate psychometric properties. Based on a non-referred sample of 300 undergraduate students, the PB-PEPQ was found to be positively associated with measures of post-event processing and social anxiety symptoms. Further, support was found for the incremental validity of the PB-PEPQ, as the measure predicted variance in social phobia symptoms after controlling for other metacognitive variables, including positive beliefs about worry and positive beliefs about rumination. Overall, the findings may have implications for cognitive models of social phobia. Further, the current findings have possible treatment implications, as individuals with social phobia may benefit from interventions focused on the identification and modification of positive metacognitive beliefs.


The roles of protein kinase C (PKC) and Li+ in N-methyl-D-aspartate (NMDA)-evoked releases of adenosine and noradrenaline (NA) were studied. In the absence of Mg2+, activation of PKC by phorbol 12-myristate 13-acetate (PMA) potentiated the release of adenosine evoked by 20muM NMDA and the release of [3H]NA evoked by 100muM NMDA. The potentiating effects of PMA on NMDA-evoked releases of adenosine and NA were reversed by inhibition of PKC with GF109,203X (GFX). GFX by itself had no effect on NMDA-evoked release of either adenosine or NA, suggesting that endogenous PKC does not play a role in NMDA-evoked releases. Li+, at concentrations of 1.5mM or 10mM, potentiated 300muM NMDA-evoked release of NA but had no effect on the release of adenosine. In the presence of Mg2+, NMDA-evoked release of NA was essentially abolished, whereas adenosine release persisted. Under these conditions, PMA or Li+ did not permit NMDA-evoked release of NA to occur, nor did they increase NMDA-evoked adenosine release. Taken together, these results indicate that PKC does not play an essential role in NMDA-evoked release of either adenosine or NA. However, activation of PKC potentiates the release of adenosine and NA evoked by submaximal concentrations of NMDA, but not by relieving the voltage-sensitive Mg 2+ block of NMDA receptors.


The dynamic behavior of groundwater flow and salt transport is affected by tide and pumping in coastal multilayered aquifers. In this paper, two groups of experiments were conducted considering different constant head inland boundaries. The fluctuation of the groundwater level and the process of seawater intrusion in the multilayered aquifers were observed. A two-dimensional SEAWAT model is developed to simulate the seawater intrusion to coastal aquifers under the influences of tidal fluctuation and groundwater exploitation. The hydrogeological parameters in the model are calibrated by the records of the groundwater level and salinity measurements. The results showed that the simulated groundwater level and salt concentration match the observation well. The groundwater level has the characteristics of periodic fluctuation with tide. The lag time of the groundwater level fluctuation in each monitoring point increases slightly with the increasing distance from the saltwater chamber. For the low tide, the inland freshwater recharge has main effect on groundwater level fluctuation. The rising tide has a negative effect on the drawdown of the groundwater level induced by pumping. For the high tide, the tide plays a major role on groundwater level fluctuation, compared with the inland freshwater recharge. Compared with the condition of high head of inland recharge, larger saltwater intrusion lengths and area have been observed and simulated in the aquifer, which means that faster inland motion of the seawater wedge would occur when the inland recharge is small in the coastal aquifers. It revealed that inland recharge plays a major role in the seawater intrusion for the same pumping rate of groundwater in different seasons. The analysis provides insights into how the tide fluctuation, groundwater pumping, and inland recharge effect on the area and rates of seawater intrusion.


It is utmost important to make continuous and comprehensive evaluation as an integral part of teaching and learning process to promote standard of Education. CCE refers Continuous & Comprehensive Evaluation, a system of school based assessment that covers all the aspects of a student's development. It was designed to reduce the student stress related to board exams, and to introduce a uniform and comprehensive pattern for student evaluation across the country. It emphasizes on two broad objectives: (a) Continuity in Evaluation and (b) Assessment of broad based learning. Clearly, it attempts to shift emphasis from 'testing' to 'holistic learning' with an aim of creating young adults, possessing appropriate skills and desirable qualities in addition to academic excellence. Therefore, the CCE scheme brings about a paradigm shift from examination to effective pedagogy. Conventionally the teacher is seen as the information giver; knowledge flows only one way, from teacher to student. In a collaborative classroom (or the CCE method), emphasis is on shared knowledge and decision making. For some teachers finding time for planning collaborative instruction is a most difficult challenge. Practicing modes and modalities of CCE is a challenge before traditional teachers. Therefore it is absolutely essential that teachers need to be provided with orientation about the CCE scheme incorporating both the scholastic and coscholastic areas of learners' growth. In order to make CCE effective there has to be collective understanding among all concern i.e. child, teacher, parent and institutions of higher education about what is being evaluated. This paper is based on ideas and basic concepts of CCE Scheme implemented in Gujarat.

CORDIC (COordinate Rotation DIgital Computer)-based VLSI architectures are very interesting for the design of frequency offset estimation and correction circuits for OFDM burst oriented systems because of the simplicity of their hardware implementation. This paper evaluates the lower realizable bound on the accuracy of fixed-point CORDIC-based frequency offset estimation and correction schemes. The proposed evaluation relies on the Cramer-Rao lower bound (CRLB) and the upper bound of the error introduced by the CORDIC algorithm. Simulations results related to the application of this evaluation scheme to a HiperLAN/2 simulation model are presented.

Let T be an operator from an Orlicz space L0 into itself.

Denote by L*(£) the system of all equivalence classes in L<¡,(ti, &, p), containing a £-measurable function, i.e. a function /: ti -> R with {/ > a) G £ for all a G R If L& = Lg it was shown in [11, Corollary 5], that for each / G L^(ti, â, p) there exists a unique p^(f\t) G L^(t) such that (*) /$(/ M£)) dp = inf {|$(/ g) dp: g G /,"(£)}.

Abstract The in-service sea-crossing bridge handles a large number of vehicles, while considerable wind exists on the superstructure and wave exists on the substructure simultaneously, on a daily basis. Apart from the service loads, the bridges may also encounter extreme natural hazards such as earthquake, hurricane, etc., which might greatly threaten the structural safety. In particular, this article attempts to illuminate the influence of the simultaneous service and extreme loads on the dynamic performance of an in-service sea-crossing bridge along with traversing vehicles. To this end, a general earthquake-wind-wave-vehicle-bridge (EWWVB) simulation platform is established, which systematically integrates the interactions between earthquake, wind, wave, vehicle and bridge. The safety indicators are also implemented in the proposed platform to enable the driving safety evaluations of the vehicles travelling on the bridge during earthquakes. With the proposed simulation platform, an illustrative example is presented in which a number of road vehicles are travelling on an in-service prototype sea-crossing cable-stayed bridge during a sudden earthquake event. The results indicate that the extreme seismic load could become the dominant load affecting the dynamic response of the prototype sea-crossing bridge as well as the vehicles running on it.


Chen Geng was the founder of the New China's first academy of military engineering, and he made a pioneering contribution to military engineering education in contemporary China. The historical background to Chen Geng's thinking about military technology education lay in the needs of China's national defense development and the Korean War. His thinking about and practice of military engineering education was chiefly expressed in four areas. 1. Military engineering education is a cornerstone of national defense modernization. 2. Its focus must be on using comprehensive quality control to train military engineering personnel with overall skills. 3. "The root of virtue lies in education, and the root of education lies in the teachers. " 4. Administration and management must serve pedagogy. Chen Geng's thinking and practice achieved brilliant accomplishments which had far-reaching influence on the fine traditions of the Harbin College of Military Engineering .

Stress and cigarette smoke are important environmental factors that can alter human health. Nicotine can modulate the individual response to psychological stress. Cutaneous wound healing is a complex process involving inflammation, granulation tissue formation, and remodeling, which result in scar formation. Chronic stress impairs cutaneous wound healing. In this study we evaluate the effects of nicotine administeration on cutaneous wound healing from chronically stressed mice. Male mice were stressed by spun at 115 rpm for 15 min per hour, daily, until euthanasia. A group of mice were only chronically stressed. A group of chronically stressed mice received daily application of nicotine patch (2mg/Kg). Control mice were not subjected to stress, but received daily nicotine patch (2mg/Kg). An excisional lesion was made and measured. Fourteen days later, mice were killed to collect blood and lesions. The inflammatory infiltrate, angiogenesis, collagen deposition, activity of matrix metalloproteinases and mieloperoxidase were evaluated in wounds. Stressed and nicotine treated‐mice showed a worst rate of contraction and re‐epithelialization than stressed animals. Nicotine treatment aggravates the delay in wound healing of stressed mice.

Aggregated observations are common data sets in various fields, including statistics, hydrology, sociology and economics. Very often classical autoregressive (AR) or autoregressive moving average (ARMA) models are used to describe such data. It was shown by Granger and Morris [?] how more complicated models can arise through an aggregation scheme. For example, adding N independent AR(1) models can produce the ARMA(N , N 1) model. This leads to the idea of accumulating infinitely many short memory processes with random coefficients, which was investigated by Granger [?] (see also the earlier contribution by Robinson [?]). One of the major results was that aggregation can lead to time series with a long memory, and since this work, a number of articles has been devoted to the study of theoretical aspects of the aggregation phenomena. For reviews in the discrete time setting, we refer to Oppenheim and Viano [?] and to Zaffaroni [?], whereas aggregation of continuous time processes was considered by Anh et al. [?, ?, ?], Leonenko and Taufer [?], Oppenheim and Viano [?], Barndorff-Nielsen [?] and Barndorff-Nielsen and Leonenko [?]. Dacunha-Castelle and Oppenheim [?] showed that a large class of long memory processes can be obtained via aggregation of short memory processes having random spectral densities, hence the phenomenon observed by Granger is far from being exotic. This subject was then further investigated by Celov et al. [?], Dacunha-Castelle and Fermine [?]. For GARCH and other volatility models, the aggregation procedure has been investigated by Zaffaroni [?] and Kazakevicius et al. [?]. To illustrate the problem, consider as an example a sequence of independent processes { X (j) k } k∈N, j = 1, 2, ... defined by


ABSTRACT THE CORRELATION BETWEEN EMOTIONAL INTELLIGENCE AND CIVIL SERVANTS' RETIREMENT ANXIETY Artika Kumala Dewi Psychology of Medical Faculty of Sebelas Maret University To civil servants, the retirement day is often considered as a future threat that can cause anxiety. The presence of the anxiety in facing the retirement day is dominantly influenced by the emotional intelligence. Higher emotional intelligence can lead to a condition which is free from anxiety. On the contrary, lower emotional intelligence will result in anxiety within an individual. This research is, then, aimed at finding out the relation between the emotional intelligence and the anxiety in facing the retirement day that happens to the civil servants. The population of the research covers all of the civil servants who work at UNS central's office. There are 431 people who are included in the population. The sample is taken from the female and male workers with the following criteria: (a) hold the position as the civil servant, (b) must be between 51-55 or are closed to the retirement day, (c) do not possess another source of earning, and (d) hold the structural rate of III or IV to ensure that they have certain position in their divisions. The purposive sampling technique is used to get the samples. The populations that fit the criteria are 80 people. The data collection uses emotional intelligence scale and the anxeity in facing the retirement scale. The data is analyzed by using the analysis of product moment correlation. The result of the analysis shows the number of the coeficient correlation (r) as much as -0.677 with the significance rate as much as 0.000 < 0.05. From the analysis, it can be concluded that there is a negative correlation between emotional intelligence and the anxiety of the civil servants in facing the retirement day. This means that the higher emotional intelligence is, the lower the anxiety in facing the retirement day becomes, and vice versa. The significance of the control of the emotional intelligence toward the anxiety is 45.8%. Keywords : emotional intelligence, anxiety, retirement.


Estimates of the generalization error are proved for a residual neural network with $L$ random Fourier features layers $\bar z_{\ell +1}=\bar z_\ell + \textrm {Re}\sum _{k=1}^K\bar b_{\ell k}\,e^{\textrm {i}\omega _{\ell k}\bar z_\ell }+ \textrm {Re}\sum _{k=1}^K\bar c_{\ell k}\,e^{\textrm {i}\omega ^{\prime}_{\ell k}\cdot x}$. An optimal distribution for the frequencies $(\omega _{\ell k},\omega ^{\prime}_{\ell k})$ of the random Fourier features $e^{\textrm {i}\omega _{\ell k}\bar z_\ell }$ and $e^{\textrm {i}\omega ^{\prime}_{\ell k}\cdot x}$ is derived. This derivation is based on the corresponding generalization error for the approximation of the function values $f(x)$. The generalization error turns out to be smaller than the estimate ${\|\hat f\|^2_{L^1({\mathbb {R}}^d)}}/{(KL)}$ of the generalization error for random Fourier features, with one hidden layer and the same total number of nodes $KL$, in the case of the $L^\infty $-norm of $f$ is much less than the $L^1$-norm of its Fourier transform $\hat f$. This understanding of an optimal distribution for random features is used to construct a new training method for a deep residual network. Promising performance of the proposed new algorithm is demonstrated in computational experiments.
