Well‐crystallized MgxZn1–xO films were deposited on quartz substrates by sol‐gel technique with a varia‐ tion of x value from 0 to 0.15. The samples were annealed at different temperatures (500 °C to 700 °C) in air and oxygen atmosphere to study the effect of annealing atmosphere on the luminescence properties of the films. The optical, microstructural and photoluminescence properties of the films were studied. It was found that the band gap of the films increased with increasing Mg concentration (x value). A remarkable change in the photoluminescence spectra of the films for x = 0.05 was observed by varying the annealing atmosphere. Highly intense UV emission at room temperature could be obtained by annealing the Mg0.05Zn0.95O film in static oxygen atmosphere, while the intensity of the visible defect related luminescence could be reduced, resulting in a high intensity ratio (∼100) of the two.

Abstract Procedures are proposed for monitoring forecast errors in order to detect changes in a time-series model. These procedures are based on likelihood ratio statistics which consist of cumulative sums. An extension of Page's method is presented which tests for changes in the parameter values of autoregressive integrated moving average (arima) models. The distributional properties of the statistics are approximated under the assumption that the series follows an integrated autoregressive moving average model. This approximation is based on the limiting Wiener process. An example is also given.


A superficial lymphatic malformation often becomes evident following an intralesional hemorrhage; often the extravasated blood spreads in the surrounding skin giving rise to a target appearance. A case of intra- and perilesional hemorrhage characterized by the saving of the nipple area is described and its pathogenesis is discussed.


: Background: Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide. Mirabegron is a novel, once-daily orally β3-adrenoreceptor (AR) agonist. Aim of the study: This work aimed at exploring the possible prophylactic effect of mirabegron on nonalcoholic steatohepatitis (NASH) induced experimentally by high fat diet in rats. Material and methods: Rats were divided into 5 groups: normal group serving as a control group, Mirabegron group, Untreated NASH group (received a high fat diet for 12 weeks), Low dose mirabegron pre-treated NASH group (treated with mirabegron 5 mg/kg/day orally for 12 weeks) and High dose mirabegron pretreated NASH group (treated with mirabegron 10 mg/kg/day orally for 12 weeks). Results: Mirabegron produced significant reduction of liver enzymes, total cholesterol, triglycerides and Low-density lipoprotein cholesterol (LDL-c) and significant elevation of high-density lipoprotein-cholesterol (HDL-c),the serum level of glycosylated hemoglobin (HbA1c), fasting glucose and insulin levels were significantly decreased with significant improvement of insulin sensitivity observed by lowering of insulin resistance index (HOMA-IR), serum adiponectin level also showed significant elevation. These results were supported by marked improvement of liver histopathology compared to non-treated group, with the best results obtained by using the high dose of mirabegron. Conclusions: These data suggest that mirabegron may have a potential usefulness in the prevention of NASH as regard to liver enzymes, lipid profile, serum HbA1c, fasting insulin and blood glucose, insulin resistance index, and serum adiponectin levels with improvement of liver histopathological changes.


Electronic displays have non-uniform regions of chromaticity. In the present paper, a novel method that evaluates the mura grade of electronic displays using a chromaticity mura index E is presented. The index E is calculated using a filtered image obtained by the color contrast sensitivity function (CSF). The experimental results showed strong relations between the human sensory evaluation scores and the mura index E values.


### Study Hypothesis

Although genome-wide association studies have discovered candidate loci for hundreds of human traits, from height to lipid concentrations, the relationships between genetic variants and the phenotypes that they influence often remain unclear. In many cases, the functions of candidate genes are not previously known or discoverable by use of standard techniques. Suhre et al hypothesized that biochemical analysis of serum metabolites can provide an important new resource to determine how some of these risk alleles may promote disease. They leveraged an extensive library of metabolites obtained by profiling human serum from 2 large European cohorts to discover previously unsuspected networks of regulatory genes, metabolites, and diseases. In combination with known human disease associations and biochemical pathways, they extracted novel gene-disease associations that merit testing in follow-up studies.

### How Was the Hypothesis Tested?

Metabolites were measured in fasting serum on the Metabolon platform with 2 separate ultra-high-performance liquid chromatography/tandem mass spectrometry injections and 1 gas chromatography/mass spectrometry injection per sample. In the first phase of the analysis, the concentrations of 258 …


Polysiloxane–polyvinyl alcohol hybrid matrix was prepared by a sol–gel technique and its capacity to bind porcine pancreatic lipase investigated. The loading of 250 units g−1 support was shown to be effective, resulting in an immobilized lipase with high catalytic activity. Both free and immobilized lipases were characterized by determining the activity profile as a function of pH, temperature, substrate concentration and thermal stability. Application of the immobilized lipase in non-conventional biocatalysis for the synthesis of surfactants and biodiesel was also analyzed. Production of sugar fatty acid esters was found to be dependent on the carbohydrate and the highest molar conversion (50% in 3–4 h of reaction) was achieved for substrates containing fructose and lauric or oleic acids. Biodiesel synthesis from babassu oil and ethanol, propanol or butanol was feasible and regardless of the kind of alcohols, results revealed that the immobilized PPL could efficiently convert triglycerides to fatty acid alkyl esters attaining yields varying from 75 to 95%.

Flood is one of the most dangerous natural disasters that occurs frequently and can affect large community areas. It has becomes the main threat to people's life and properties. Therefore, flood prediction has long been a popular subject matter to researchers around the world. This is because an accurate and reliable flood prediction is very much needed to provide early warning for residents nearby flood locations for evacuation purposes. Therefore, this paper proposed a 5 hours flood prediction modelling for Kuala Lumpur flood prone area using Neural Network Autoregressive Model with Exogenous Input (NNARX) and its Improved Modeling technique. The samples used for model training, model validation and model testing must be the data when flood events happened to obtain a good prediction model. All samples were real-time data requested from Department of Irrigation and Drainage Malaysia upon special request. Model validation and model testing were conducted to observe the prediction performance. The improvement technique was implement to improve the prediction performance from the original structure of NNARX model. The 5 hours NNARX flood water level prediction model and the Improved NNARX model have been successfully developed, analyzed and tested using MATLAB Neural Network Toolbox. Results show that the NNARX model successfully predicted flood water level 5 hours ahead of time.

A novel robust bit loading algorithm with uniform power constraint under desired rate for OFDM is proposed. In this algorithm, only strong subchannels are used to transmit data. The number of active subchannels is determined by a criterion named capacity criterion, then power is allocated among active subchannels. The most significant novelties of this algorithm are that two modulation schemes are used at most and only one bit channel state information (CSI) for each subchannel is needed to transmit back. It has low complexity, while it has familiar performance with that of Fischer's algorithm. Our algorithm has obvious advantage in deep fade channel models. It is a promising technique in future wireless communication under TDD mode


Location of the Winchester quadrangle relative to major structural blocks of the northern Peninsular Ranges batholith. Conventional potassium-argon biotite ages of Cretaceous granitic rocks are hand contoured, and are considered to reflect the cooling history of the batholith rather than representing ages of emplacement. Contouring of ages in each of the three structural blocks separated by the Elsinore and San Jacinto fault zones, was done independently of ages in adjacent blocks. Red band shows offset of 98 to 108 contours across Elsinore fault zone. Faults as shown are simplified from Rogers, 1965. 63 37 Sample locality, showing sample numbers and potassium-argon ages.


Electrochemical detection is an analytical method that has been used for a wide range of purposes, including trace chemical analysis, glucose and neurotransmitter monitoring, DNA and protein detection, and electrocatalysis. Scanning electrochemical microscopy maps changes in the local electrochemical current along a surface in a serial way, but serial probing can disrupt the process under study. Shan et al. (p. [1363][1]) show that optical measurements of surface plasmon resonances can be used as a less disruptive way of determining the concentration of electrochemically active species on gold-coated glass slides and their current density. This method can be used for a wide range of applications from analyzing DNA and protein microarrays and enzyme-amplified biosensors to probing the activities of cells.

Abstract : A sympathetic flare is defined as one which starts through some influence of another flare which erupted earlier. At least one example as been observed directly. Pure chance should produce many simultaneous flares. Several authors have tested the statistical reality of sympathetic flares by comparing the observed and expected numbers of simultaneous flares. Results of such studies have been contradictory. One method has been applied to Sacramento Peak flares during the IGY, with definitely negative results. T e statistical methods are examined critically, with the conclusion that sympathetic flares must be very rare. (Author)


fundamentally opposed to the antiocularcentric and anti Enlightenment tendencies in contemporary French thought. His 'synoptic survey' of such propensities in the philosophy and culture of France is aimed squarely at combating the anti-modern, ahistorical and antiocular centric philosophy of Lyotard. But whether Jay's admirable commitment to the ideals of modernity can halt the postmodern tide is another question.


To study the sermons of F. De sales first requires to clear up what we know about the text, the way it was handed down to us, its editions, as the corpus is composed of, oral gatherings' (recueillis) and of autographs. Then comes a very extensive study of what is currently known about the oratorical background in those days, which makes it possible to deal with the salesian theoretical texts, to locate their filiation and their originality. Finally takes place the theological perspective of the sermons which constantly confronts to the whole work as the bishop's scotism influences the whole of his reflection upon God and man. Thus can be explained the spirituality of the sermons (characteristic of the whole work), here studied in connection with a few points only. Nothing platonic about them if only some sources, quite common then (but entirely renewed by the hebraic thought and its approach), and a certain way of writing. Everything converges on the merry mystery of the visitation : oratory and style (namely the choice of images and some tropes) as well as any reflection on incarnation, on God as trinity and love, God as benevolence" bent to communication", man as an image of a trinitary God, thus partaking of the unity of diversity, easter, whitsun, the transfiguration, as well as christmas. "God made himself a man so that man may be made God" and "man is created for bliss just as bliss for man". Within other texts, the appendix is constituted of unpublished items, sermons attributed to the bishop and the research card index of F. De sales works


【The objective of this paper was to quantitatively analyze the effect of concentrated animal feeding operations (CAFO) NPS pollution on a small watershed water quality. Monitoring was conducted from March to October, 2013. Monthly flow rate and selected water quality at each monitoring site were measured during dry days. Rainy day monitoring also was conducted. Modeling was conducted to evaluate the effect of CAFO NPS pollution on the water quality at the watershed outlet. The highest and mean concentration of selected water quality indices during rainy days were higher than those in dry days in general. The highest TN concentration measured at the CAFP pollution discharge point was 237.831 mg/L. The results revealed that the CAFO NPS pollution sources could be equally blamed for the water quality degradation of the stream. However, the effect of the NPS pollution from CAFOs seemed not to be very influential to the watershed water quality at the outlet. SWAT modeling revealed that the TN load was reduced by 18.95 %, 23.39 % and 30.53 % at the watershed outlet if the TN load at the CAFO NPS pollution discharge point reduced by 20 %, 40 % and 60 %, respectively. It was thought that the natural attenuation processes played an important role. The modeling was based only on the assumption of the load reduction and not verified by the monitored data. Therefore, it was suggested that a long term monitoring studies for the evaluation of the impact of CAFO NPS pollution on the watershed water quality be conducted.】


Thin-film waveguides were prepared by polymerization of aromatic organic compounds in a high-frequency discharge. The refractive indices and the losses in the films were determined. Heat treatment of orthoxylene films reduced the refractive index and the film thickness; heating to 160°C increased the losses in the films.


In the Software development life cycle (SDLC) the prediction of software defects is one of the crucial parts. Recent years have witnessed various studies for predicting software defects, and most of them involve machine learning techniques. Before predicting the defects some pre-processing steps are required, such as feature selection, outlier removal, and feature scaling as it helps in improving accuracy and reducing the execution time(ET). The present investigation focuses on feature selection which is a dimensionality reduction technique. Further, we have also proposed a framework on module-based software defect prediction using feature selection techniques. These techniques are divided into three categories i.e filter methods, wrapper methods, and hybrid methods that combine two wrapper methods i.e. Sequential Forward Selection and Sequential Backward Selection that we have developed. Finally, classification has been performed by KNN, Logistic Regression, Decision Tree, and SVM using the above-mentioned feature selection techniques on eight publicly available Promise datasets and compared them with the existing state-of-the-art(SOTA) methods. The result shows that the hybrid method performs better in terms of accuracy by 4.2%, 3.9%, 3.8% on datasets pc4, jm1, kc2 respectively when applied along with machine learning, as compared to filter and wrapper methods.

There are challenges that lie in migrating enterprise applications into the cloud .Certain enterprises might want data to be partly hosted on premise in the enterprise and also partly hosted in the cloud, while other enterprises might their applications to be fully hosted on the cloud. Such hybrid possibilities can enable enterprises to benefit from cloud-based architectures, while honouring application performance requirements, but privacy issues and security considerations is always a problem during migration. This work highlights the need for security in the cloud; Different features offered by cloud providers are explored. Concepts like Virtual machine migration and a hardware chip that can be used as a basis for trust in the cloud are discussed. Pre-migration hints shows what needs to be done before the actual secure migration paths set-in. The migration path is based on a generalisation of the kind of threats these features are exposed to. There are arguments as to why such paths are the most secure. It is a fact that cloud computing infrastructures enable companies to cut costs by outsourcing computations on-demand, however, clients of cloud computing services currently have no well acknowledged means of verifying the confidentiality and integrity of their data and computation. To address this problem, it was part of the migration strategy in this work to design a system that enables a cloud provider to provide an execution environment that guarantees integrity in the execution of virtual machines for its clients, but the design works in hand with a trusted third party.

During this study, a high frequency model of transformer is proposed which is capable of eliminating the effects of transients applied on transformer. The conventional transformers use surge arrestors to remove these kind of effects, but they also transfers the effects of transients on secondary side which are hazardous for electrical equipment's. Our proposed model is capable of eliminating the effects of transients without any major change in secondary voltage. This method is based on two-port network (T model) theory. The results of our method are examined and evaluated by computer simulations based on MATLAB.


The vanadium silicalite (VS-2) catalyst was hydrothermally synthesized, and a molecular level characterization was carried out by means of in situ photoluminescence, XAFS, ESR, FT-IR, UV−vis, solid-state wide-line 51V NMR, and XRD in the presence or absence of reactant molecules. These spectroscopic investigations of the VS-2 catalyst clearly show that the vanadium oxide moieties are incorporated within the zeolite framework as tetrahedrally coordinated vanadium oxide species having a terminal vanadyl group (VO) with a bond distance of 1.64 A and three VO bonds with a bond distance of 1.73 A. VS-2 catalyst also exhibits a charge-transfer absorption band at around 270−340 nm and an intense phosphorescence spectrum as a radiative decay from the charge-transfer excited triplet state at around 450−550 nm with a vibrational fine structure at 77 K. UV irradiation of the catalyst in the presence of NO was found to lead to the efficient photocatalytic decomposition of NO into N2 and O2 at 295 K. Dynamic studies o...


Special designs of two types of electronic components transistors and transmission lines have been conceived to optimize the performances of these components as parts of waveguide-embedded differential-amplifier monolithic microwave integrated circuits (MMICs) of the type described in the immediately preceding article. These designs address the following two issues, the combination of which is unique to these particular MMICs: Each MMIC includes a differential double-strip transmission line that typically has an impedance between 60 and 100 W. However, for purposes of matching of impedances, transmission lines having lower impedances are also needed. The transistors in each MMIC are, more specifically, one or more pair(s) of InP-based high-electron-mobility transistors (HEMTs). Heretofore, it has been common practice to fabricate each such pair as a single device configured in the side-to-side electrode sequence source/gate/drain/gate/source. This configuration enables low-inductance source grounding from the sides of the device. However, this configuration is not suitable for differential operation, in which it is necessary to drive the gates differentially and to feed the output from the drain electrodes differentially. The special transmission-line design provides for three conductors, instead of two, in places where lower impedance is needed. The third conductor is a metal strip placed underneath the differential double-strip transmission line. The third conductor increases the capacitance per unit length of the transmission line by such an amount as to reduce the impedance to between 5 and 15 W. In the special HEMT-pair design, the side-to-side electrode sequence is changed to drain/gate/source/gate/ drain. In addition, the size of the source is reduced significantly, relative to corresponding sizes in prior designs. This reduction is justified by the fact that, by virtue of the differential configuration, the device has an internal virtual ground, and therefore there is no need for a low-resistance contact between the source and the radio-frequency circuitry. The source contact is needed only for DC biasing. These designs were implemented in a single-stage-amplifier MMIC. In a test at a frequency of 305 GHz, the amplifier embedded in a waveguide exhibited a gain of 0 dB; after correcting for the loss in the waveguide, the amplifier was found to afford a gain of 0.9 dB. In a test at 220 GHz, the overall gain of the amplifier- and-waveguide assembly was found to be 3.5 dB.


In the present study physical characteristics and percentage of carvone were determined in spearmint oil. The Specific gravity was 0.920 to 0.940 (0.914 to 0.934 at 25°); rotation was 36° to-50°. Soluble in its own volume of alcohol (95 per cent.), forming a clear solution; also soluble in all proportions of absolute alcohol, and in about its own volume of alcohol (90 per cent.), the solution becoming opalescent on adding more solvent. The chief constituent of the oil was carvone. Boiling-point was 230°C. It is an unsaturated ketone, having the formula C10H14O, and is a colourless liquid, smelling strongly of caraway, and solidifying on refrigeration. The chromatogram obtained by GLC type NUCON 5700 (Gas liquid chromatography) depicted that the percentage of carvone in the oil sample was 82% concluding that its effectiveness was more than other oil.


We present a method to correct the magnetic properties of itinerant systems in the local-spin-density approximation (LSDA), and we apply it to the ferromagnetic-paramagnetic transition under pressure in a typical itinerant system Ni3Al. We obtain a scaling of the critical fluctuations as a function of pressure equivalent to the one obtained within Moryia's theory. Moreover, we show that in this material the role of the band structure is crucial in driving the transition. Finally, we calculate the magnetic moment as a function of pressure and find that it gives a scaling of the Curie temperature that is in good agreement with experiment. The method can be easily extended to the antiferromagnetic case and applied, for instance, to the Fe pnictides in order to correct the LSDA magnetic moment.

Over the last two decades, computer technology has become an integral part of any business strategy and operation, including non-ICT ventures. In fact technological innovations have very much driven business growth where the capability of companies to embrace, maintain or lead in developing new technologies has shaped contemporary practice. In preparation for entering this dynamic workplace environment, it is necessary to consider how best to educate the entrepreneurial employee and how to expose students and trainees to these newer technologies. A delivery approach that allows for a combination of information communication technologies (ICT) to be used in education and training is termed ICT-enabled learning. Since the modern learner is inclined to engage with a wide range of ICT-enabled technologies, techno-familiarity can create a comfortable learning zone. As a result, ICT-enabled learning can be provided in universities and within modern day firms. This chapter explores entrepreneurship education through the lens of ICT-enabled learning within university education. In the case study presented, learners extol the benefits of ICT-enabled learning on their entrepreneurship module. There are a number of implications for employers and educationalists. In this chapter, the value of entrepreneurship education via ICT-enabled learning is discussed. For the entrepreneurial firm, recommendations are made about providing training in entrepreneurship for employees.


The article deals with an issue of complex systems operation efficiency, especially of the ones which are connected with transport. The operation of such systems aims at developing both passenger and load transportation in terms of safety, reliability, effectiveness and environment friendliness. These properties should be researched in a particular place and time that were earlier planned and selected. Operation effectiveness is an important component of widely understood social-economic and technological research, including assessment of the considered transport system. The concepts of operation efficiency, most frequently used in literature, express it as the relation between benefits (treated as profit or income in terms of economy) and costs. However, a ratio of two quantities, the first of which is evaluated positively, that is, aims at reaching the highest values and the other one being negative, is considered as the most important definition of efficiency. In some cases these quantities can assume constant values, treated as basic ones. It should be remembered, though, that in many cases the system goals are formulated in different terms than, e.g. economic ones. And the systems should be evaluated taking into consideration the goal achievement degree. The article deals with an analysis of distinguished values of selected assessment indices for an investigated transport system, and on this basis an assessment of the transport system operation efficiency, in a given period of time, has been made.


The dose dependence of K.(( ), promotion of two-stage urinary bladder carcinogenesis and the amplifying effects of additional L-ascorbic acid (ÂsA) administration were investigated. Male F344 rats were given 0.05% /V-butyl-A'-(4-hydroxybutyl)nitrosamine in their drinking water for 4 weeks and then fed basal diet containing K,.(.'(), at levels of 0, 1, 1.5, 2.2, and 3% with or without 5% AsA or 3% NaHCO3 supplemen tation from weeks 5 to 8 (4 weeks) and weeks 12 to 20 (9 weeks). During weeks 9 to 11 (3 weeks), the rats were fed 3% uracil in their diet. For controls, rats without A'-butyl-/V-(4-hydroxybutyl)nitrosamine treatment were given either 3% K2CO3,5% AsA, or both plus the uracil treatment. The total observation period was 20 weeks. K:(O, dose dependent!}' increased the numbers of the putative preneoplastic lesion, papillary or nodular hyperplasia, and papillomas in rats initiated with .V-bui)l-.V-(4hydroxybutyl)nitrosamine. AsA (5%), while itself exerting no promoting effect, amplified the enhancing influence of K.( ()( on the induction of papillary or nodular hyperplasia and papillomas. The dose-dependent elevation of urinary pH and K*concentration was associated with K,C'(), treatment with or without AsA. Thus, increased urinary pH and K* concentration appear to play important roles in K:< ()< promotion, and AsA amplifies this promotion.

Hepatocellular carcinoma is a fatal liver cancer, and there are limited treatment options for this cancer. c-Myc is a key oncogene in liver cancer, but the specific mechanism of carcinogenesis in liver is unknown. Animal models are widely used to explore the molecular pathogenesis of HCC and test new drug candidates. In this poster, we reported a c-Myc conditional over-expression mouse model (LSL-Myc), which inserts the CAG-Loxp-stop-Loxp-c-Myc-polyA expression cassette into the H11 site. The expression of the Myc gene in this mouse model is regulated by Cre recombinase, which is not normally expressed, but only expressed in Cre-expressing tissue cells. LSL-Myc / Alb-cre double-positive mice were produced by crossing LSL-Myc hybrid mice with Alb-cre mice. In this mouse model, c-Myc was specifically expressed in liver cells. LSL-Myc / Alb-cre double-positive mice show a typical HCC phenotype and show accelerated tumor initiation and rapid HCC progression. Mice can detect significant liver tumorigenesis at 2 months of age, and 100% mice can occur hepatocellular carcinoma. The liver cancer tissues from LSL-Myc / Alb-cre double-positive mice can be transplanted to C57BL/6 mice to establish a mouse-derived PDX model. In summary, this model has the advantages of rapid oncogenesis and high incidence of liver cancer.

A Gurney flap is a thin strip of material attached at the trailing edge of the upper surface of a racing car wing in order to increase the downforce of a wing of limited size. The flow around a single element racing car wing with and without a 4.7% Gurney flap has been investigated experimentally and computationally. Attention has been concentrated on the unsteady wake which is characterized by alternate vortex shedding as is observed behind circular cylinders, flat plates and other two-dimensional bluff bodies. Using novel experimental and postprocessing techniques it has been possible to determine the instantaneous velocity and pressure fields in the intermediate and far wake. The fluctuating pressures on the surface of the aerofoil have been measured and integrated to determine the fluctuating lift and pitching moment on the wing. These were found to be small compared with the time-averaged values despite the strong fluctuations in the wake. Steady-state computational fluid dynamic simulations were performed and the aerofoil surface pressure distribution was predicted accurately. The relationship between wake unsteadiness and the pressure acting on the rear of bluff bodies (the base pressure) is discussed and its importance to Gurney flaps is assessed.


While the mining process of Guanyintang Coal Mine was digging into the depth,in some area,rib spalling,the floor heave and the pressure acted on the roof appeared,consequently,the twisted phenomenon of legs,beams and shed occured.Solving these problems will need much time,and the restoration work is hard.In view of present mining conditions,the new pressure-release technology by drilling bore holes was used in Guanyintang Coal Mine,which reduced the deformation of the roadway.The application of this technology ensured the safety of roadway.


We present an optical surface in closed form that can be used to design lenses for controlling relative illumination on a target surface. The optical surface is constructed by rotation of the pedal curve to the ellipse about its minor axis. Three renditions of the surface are provided, namely as an expansion of a base surface, and as combinations of several base surfaces. Examples of the performance of the surfaces are presented for the case of a point light source.

Their pragmatical meaning is characterised: grandeur and inviolability of the USSR.


A case of 65 years of old female in which Reed-Sternberg cells were found in brush specimens from bronchial mucosa is reported. Histopathologic specimens from bronchial mucosa and lymph nodes were estimated too. We would like to direct attention to the necessity differential diagnosis Reed-Sternberg cells with adenocarcinoma cells in brush specimens from bronchial mucosa.


ABSTRACT Human consumption of sea urchin gonads has led to overexploitation of commercial species, and the search for new marketable species to promote the recovery of exploited populations. Echinometra vanbrunti is a promising candidate for commercial exploitation. Its annual reproductive cycle has an effect on the proximate composition of the gonads; if they were to be consumed, the best quality in biochemical composition was determined to be from December to May, when nutritive phagocytes uphold the highest contents of protein and lipid. They possess considerable levels of omega-3 essential fatty acids, predominantly eicosapentaenoic and docosahexaenoic (DHA) acids, quite important for human nutrition. A subtle trend of higher DHA levels during the growing, premature, and mature gonadal stages of females and males was observed, though it is strongly influenced by diet and environment. A program to protect and regulate the sustainable extraction needs to be put in place before commercial exploitation.


The cultural ecological background of Heroic Son is as follows.At the beginning of the 20th century,the old literature represented by the townsfolk literature identified culturally and aesthetically with the old literature and old arts represented by the lower urban classes.In comparison with the new century(20th century),the traditional sense of arts integrated leisurely with the psychological modules of the old drama and old opera in the new form of movies.


cannot draw; I cannot build three dimentionally; I cannot tell very many artists by looking at their works; I could not teach a course on art appreciation or history. But I am deeply interested in the arts as a consumer. I am anxious that all youth have favorable relationships with the arts while in school, and I represent the average administrator with whom you work who supports art programs within the school. From these experiences, prejudices, and positions, then, let me speak. '


Analytical solutions of the Stokes equations written as a differential equation for the Stokes stream function were obtained. These solutions describe three-dimensional axisymmetric flows of a viscous liquid inside a drop that has the shape of a spheroid of rotation and have a similar set of characteristics with Taylor flows inside bubbles that occur during the transfer of a two-component mixture through tubes.


There is increasing evidence that a combination of natural cycles and human behaviors is changing the global climate. Civil Engineers responsible for the design and operation of infrastructures and utilities need to be prepared to ameliorate the consequences for the sake of both their businesses and society in general. This paper proposes a generic process for, and demonstrates a performance-based approach to, the assessment of impacts, and the consequent adaptation and mitigation interventions on the UK Electricity Supply Industry as an example of a complex infrastructure. It shows how the combination of simulation software, through which various climate change scenarios can be run, interfaced with a performance management software tool, can produce powerful decision support tools for the industry. The simulation models are implemented in the Simulink®, while the PeriMeta software is developed for performance assessment and decision aid. The effects on system performance of various interventions to enhance, for example, flood protection can be investigated using an embedded argumentation structure. Four climate and socio-economic scenarios of capacity and demand are fed into the simulation. The model can then be run over various timescales to show the implications for long-term planning of capacity and short-term for the prediction of possible overloads and failures of the system components.

I The Oxford Handbook of Political Theory is one of a series of handbooks on political science published by Oxford – the others being: 'Contextual Political Analysis' and 'Public Policy' Political Institutions Political Behavior Comparative Politics Law and Politics Political Economy International Relations Political Methodology Its range is very wide and certainly – as the table of contents attests to – goes beyond what has usually been conceived of as political theory. The contents are divided into 11 parts – 'Introduction', 'Contemporary Currents', 'The Legacy of the Past', 'Political Theory in the World', 'State and People', 'Justice, Equality and Freedom', 'Pluralism, Multiculturalism, and Nationalism', 'Claims in a Global Context', 'The Body Politic', 'Testing the Boundaries' and 'Old and New' – and 46 chapters. The chapters do indeed attest to the very heterogeneous and diversified thematic approach to political theory, and the geographical spread thereof, including for instance chapters on Islamic and Confucian theories and on the European Union – as well as a rather original chapter on American exceptionalism from the point of view of the American political self-conception and not, as in the work of S.M. Lipset or Daniel Bell, from the point of view of the non-development of socialism in the US or, as has been presented by Luis Hartz, from the point of view of the distinctiveness of American liberalism. Needless to say, one can find also topics which have not been taken up in separate chapters, such as for instance war or Empires – the references to the latter being closely connected to post-colonial discussion – or terrorism which is not to be found in the index and the discussions thereof are dispersed throughout different chapters. But such a situation is in a sense unavoidable – not all the topics which could bear in some way on political theory as it is conceived here could possibly be included.

Herbivorous zooplankton species (Calanus plumchrus, Paracalanus parvus and Euphausia paci~ca) and carnivorous species (Parathemisto pacifica and Pleurobrachia pileus) collected from Saanich Inlet, British Columbia, Canada, were maintained in the laboratory under fed and starved conditions. Respiration rate and excretion rates of ammonia and inorganic phosphate were measured successively on the same batch populations of each species in different feeding conditions. Respiration rate remained at a constant level or increased during the feeding experiment but decreased progressively in starved individuals. Herbivorous, but not carnivorous, species showeda rapid decrease in both excretion rates for the first few days of an experiment irrespective of feeding conditions. However, the general level of excretion rates of fed specimens was higher than that of starved ones. The O:N, N:P and O:P ratios were calculated from respiration, ammonia excretion and phosphate excretion and discussed in relation to metabolic substrates of animals during the experiment. A marked difference was shown in the O:N ratio between fed herbivores (>16) and fed carnivores (7 to 19), suggesting highly protein-oriented metabolism in the latter. One unknown factor causing variation in excretion rates is speculated to be the physiological stress on animals during sampling from the field. It is suggested that the laboratory measurement of realistic excretion rates of zooplankton is difficult owing to their large fluctuations, but this is not the case with respiration rate.


Background: Direct oral anticoagulants (DOACS) are approved for use in non-valvular atrial fibrillation (AF). This systematic review and meta-analysis aimed to evaluate the efficacy and safety of DOACs vs. warfarin and update the evidence for treatment of AF and valvular heart disease (VHD). Methods: We identified randomized clinical trials (RCTs) and post-hoc analyses comparing the use of DOACS and Warfarin in AF and VHD, including biological and mechanical heart valves (MHV), updating from 2010 to 2020. Through systematic review and meta-analysis, by using the "Rev Man" program 5.3, the primary effectiveness endpoints were stroke and systemic embolism (SE). The primary safety outcome was major bleeding, while the secondary outcome included intracranial hemorrhage. We performed prespecified subgroup analyses. Data were analyzed by risk ratio (RR) and 95% confidence interval (CI) and the I-square (I2) statistic as a quantitative measure of inconsistency. Risk of bias and methodological quality assessment of included trials was evaluated with the modified Cochrane risk-of-bias tool. Results: We screened 326 articles and included 8 RCTs (n = 14.902). DOACs significantly reduced the risk of stroke/SE (RR 0.80, 95% CI: 0.68–0.94; P = 0.008; moderate quality evidence; I2 = 2%) and intracranial hemorrhage (RR 0.40, 95% CI: 0.24–0.66; P = 0.0004; I2 = 49%) with a similar risk of major bleeding (RR 0.83, 95% CI: 0.56–1.24; P = 0.36; I2 = 88%) compared to Warfarin. Conclusions: In this update, DOACs remained with similar efficacy and safety compared to warfarin in thromboprophylaxis for AF and VHD.


The invention discloses a mechanical uniform dispersion method of iron 15 copper-3 graphite semi-solid state slurry and belongs to the field of research on the mechanical uniform dispersion of the iron 15 copper-3 graphite semi-solid state slurry. In the invention, a mechanical preparation method is adopted, and a double-vane layer mechanical stirrer is utilized for mechanically and uniformly dispersing the iron 15 copper-3 graphite semi-solid state slurry under the conditions that the radians of cambered surfaces of the upper-lower double-surface cambered straight vanes are respectively 60-62 degrees and 30-32 degrees.

A short length of transmission line can be chosen as a basic circuit element. Systems containing such elements can then be synthesized to do an amazing number of things. For example, commensurate lines, all multiples of a given length with differing characteristic impedances but with common propagation constant, can be interconnected to realize microwave filters, broad-band transformers, broad-band delay lines with amplitude selectivity, and distributed RC structures. The fundamental ideas underlying the synthesis of commensurate transmission line circuits are presented in this paper in a tutorial fashion. The presentation is based on the scattering formalism and Richard's Theorem. The discussion is liberally sprinkled with design illustrations chosen from current practice.


We consider the computation of output functionals of random solutions to elliptic boundary value problems in domains with random boundary perturbations. We use a second‐order shape calculus to linearize the problem around a fixed nominal domain. For known mean and two‐point correlation function of the boundary perturbation, we derive, with leading order, deterministic expressions for the mean and the variance of the random output functional. These expressions include the solution of the boundary value problem on the nominal domain and a further, deterministic solution of the so‐called adjoint equation. The theoretical findings are supported and quantified by numerical experiments. Copyright © 2009 John Wiley & Sons, Ltd.


A CRITICAL ANALYSIS OF THE THEOLOGICAL METHOD OF F. LERON SHULTS Joshua Philip Boswell, Ph.D. The Southern Baptist Theological Seminary, 2012 Chair: Dr. Stephen J. Wellum This dissertation evaluates the theological method of F. LeRon Shults. Shults's attempt to develop theology in light of the postmodernism milieu i s a legitimate and necessary enterprise for evangelical theologians. His emphasis on inter disciplinary dialogue may open opportunities to engage the secular academy. Despite his laudabl e motivation and the beneficial features of his project, it fails on at least tw o counts: biblical fidelity and internal consistency. Chapter 1 sets the cultural/theological context for Shults's project and brie fly describes his proposed theological method. In his method the philosophical turn to relationality is a key theme. He proposes four sources for theological m ethod—Scripture, tradition, philosophy, and culture—claiming that Scripture is the primary s ource. Shults's theology, however, is inconsistent with his proposal. He allows philosophy rather than Scripture to play the determinative role in his theological method. Chapters 2 and 3 describe Shults's theology. Chapter 2 describes Shults's use of Scripture in his theological method as well as his use of tradition. I show that bot sources are used as secondary supports to Shults's use of philosophy. Chapter 3 describes the place of philosophy in Shults's theological method. He allows the philosophical turn to relationality to drive his theological project. For Shults , philosophy judges and forms the content of theology. Chapters 4 and 5 evaluate Shults's use of the four sources mentioned above, arguing that Shults affords too little authority to Scripture and too much authori ty to philosophy. Chapter 4 shows that, despite the authoritative place of Scripture in evangelical theology and the Bible's self-attestation to its authority , Shults does not give Scripture enough authority in his project. Chapter 5 shows that Shults allows philosoph y and science to hold more authority than they warrant. Philosophy, for Shults, determine s the limits of exegesis and theology. In his program, theology must conform to the philosophical turn to relationality and contemporary science rather than have philosoph y and science stand under the evaluative judgment of the biblical text. In short, Shult s's theology is unbiblical and inconsistent. VITA Joshua Philip Boswell PERSONAL Born: February 25, 1976 Parents: Andrew S. and Beverly N.

ments: the centrality of the idea of race in nationalism and transnationalism, and intimacy as a potent theoretical tool for addressing social inequality in global popular cultural studies and postcolonial studies. For all of this, she has abundant ethnographic evidence and has presented it skillfully. While it is hard to find criticism for a well-researched and well-written book, Bigenho's attempt to explain the Japanese-Bolivian connection could be enhanced. Although Bolivian and Japanese nationalisms may provide an important ideological backdrop, other, perhaps less ideological, factors, such as Japanese masses' long fascination with archaeology in general and the Andean civilization and Inca empire in particular, along with the history of Japanese foreign aid to Bolivia and resulting Japanese presence there, as well as Japanese society's voracious adoption of "foreign" popular cultures generally, could contextualize the transnational nexus in a more grounded manner. Bigenho need not defend her position as a Latin Americanist researching in Japan, since the classic ideal of complete immersion in an ethnographic "field" is nowadays largely recognized as illusory anyway; she could have, however, explored a wider range of Japanese-language sources on Japanese affection for Bolivian folk culture and Bolivians' acceptance of Japanese fans and performers. In this regard, her Latin Americanist background might indeed have limited her research. This minor quibble aside, Bigenho's engaging ethnography is a valuable resource on popular culture and (trans)nationalism in Japan, and it offers a welcome departure from the tired West versus East dichotomy that has long dominated theories of cultural globalization.


Water, specifically in a hydration shell, is critical for many biological supramolecular aggregations in nature, where water can directly mediate intermolecular association via hydrogen bonding and is regarded as "structured water". Conversely, little has been reported on the biomimetic water-mediated supramolecular assembly with adequately high water content to date, because of the competing thermodynamic processes of water hydration and water as a building block to participate in self-assembly. In this work, we explore water-mediated complexation based on entropy-driven biphasic coacervate formation using highly hydrophilic neutral polymer and inorganic mineral-analogous nanoclusters. For the first time (to the best of our knowledge), nonelectrostatic liquid–liquid separating coacervate formation is demonstrated between polyethylene glycol (PEG) and polyoxometalate (POM) nanoclusters in aqueous solutions of varied PEG and POM concentrations, POM types, and aqueous medium conditions. Comprehensive charac...

Introduction: We investigated the transport durability of mudstone aggregates as aeolian bedload, in order to evaluate if mudstone aggregate grains could potentially form aeolian dunes. Whereas we commonly think of monomineralic grains and hard rock fragments when talking about aeolian dunes, there are reports of modern examples that form when mud/mudstone aggregates are transported by wind. Known under names like "clay dunes" and "soil sands", they form when winds rework desiccated mud crusts. In addition, in modern deserts in which mudstones are the dominant bedrock, surface aeolian sediments can include sand size mudstone lithics. Fossil analogs of aeolian sands sourced from a fine grained protolith or penecontemporaneous dried mud could be "hidden" in ancient floodplain and lacustrine deposits on Earth as well as on Mars. Methods: Sand size soft mudstone fragments were placed in a circular wind chamber, where sustained air flow (ca. 25 km/hr) was generated by a motor-driven propeller. Grain size distribution and rounding of this "mudstone sand" was tracked over the course of an 18 month experiment. The part of the sediment load that turned into dust was removed by running the air in the chamber through a vacuum cleaner. Continuous grain motion was mainteained at low level saltation and grain creep. Results: Over the duration of the experiment, average grain size diminished from very coarse to coarse sand size, and grain rounding changed from angular to well rounded (Fig. 1). From film clips of the moving grain carpet, we estimated the average rate of grain movement per film frame, and also the distance of grain movement as long as the grains stayed within the field of view. Grains that moved past the field of view could not be counted, thus our measure of grain travel per unit area and time is a minimum estimate. Our data suggest that under given conditions it would take 3 years for 50% of the original grains to be destroyed, at a mimumum average travel distance of ca. 2.7 km. For reduction of the original grains to 10%, approximately 5 years will need to pass, at a mimum average travel distance of 5 km. Given that we are not able to evaluate the travel distance contribution by faster moving grains (past field of view), the real travel distance must be significantly larger, most likely in excess of 10 km. Figure 1: Grain shape change over to duration of the experiment. (A) through (C) shows how rounding improves in the very coarse (1.4-2 mm) sand fraction over time. A=start; B=185 days, C=530 days. (D) shows the rounding of the coarse sand fraction (0.42 to 0.5 mm) at the end of the experiment (530 days).


The total quantity of metals (Mg, Ca, Ni, Fe, Mn, Zn, Cu) in soil samples and in sixteen different extracts from plant parts of Peucedanum oreoselinum (L.) Moench as well as the content of total phenols and flavonoids in plant extracts was determined. The contents of metals were determined by the atomic absorption spectrometer. Based on the average values of the metal concentration in the soil, they could be arranged in the following sequence: Fe > Ca > Mg > Mn > Zn > Cu > Ni. Soil concentrations of all tested metals were lower than the maximum allowed concentration. The results demonstrated that the analyzed plant extracts contained higher quantities of Ni and Ca. Although the studied species accumulate analyzed metals in different quantities, they are not hyperaccumulators of these metals. Total phenols were determined using Folin-Ciocalteu reagent and their amounts ranged from 1.94 to P. oreoselinum, hyperaccumulation, phenols, flavonoids32.38 mg GA/g. The amounts of flavonoids in plant extracts were in range from 0.69 to 25.83 mg RU/g. We examined the correlation of metals and the phenolic compounds content in the extracts. According to our results the use P. oreoselinum for tea preparation is safe to a great extent for people, because in spite of the determined metal absorption by plant organs, the tea does not contain dangerous quantity of heavy metals. Also, it is suitable for the preparation of teas and herbal extracts due to minimal content of toxic metal (Ni), phenols and flavonoids.

Five American Cyanamid Company experimental organophosphorus systemic insecticides, compounds 43064, 43356, 47031, 47071, and 47470, have been evaluated in the laboratory and greenhouse to determine their usefulness for systemic control of cotton-insect pests. Topical treatments of adult boll weevils, Anthonomus grandis Boheman, with the 5 experimental insecticides indicated that they were more toxic than phorate, but resulted in unusually flat dosage-mortality curves. Seed treatments of cotton with compounds 43064, 43356, and 47071 gave excellent control of adult boll weevils in greenhouse experiments for 10 to 11 weeks. Treatments with the phorate standard controlled weevils for only 6 weeks. Field experiments, however, indicated that compound 43064 was no more effective than phorate for control of aphids, thrips, or boll weevils,

Chemical names of American Cyanamid Company compounds tested are: 43064, cyclic ethylene (diethoxyphosphinothioyl) dithioimidocarbonate; 43356, cyclic ethylene (dimethoxyphosphinothioyl) dithioimidocarbonate; 47031, cyclic ethylene (diethoxyphosphinyl) dithioimidocarbonate; 47071, cyclic propylene (diethoxyphosphinothioyl) dithioimidocarbonate; 47470, cyclic propylene (diethoxyphosphinyl) dithioimidoearbonate.

The angiotensin-converting enzyme (ACE) was discovered in 1956 and has been actively studied to date. It has a unique structure of two homologous domains, each containing a catalytic zinc ion. Domains have different substrate specificity. In terms of function, ACE is a zinc metallopeptidase widely present on the surface of endothelial and epithelial cells. The gene encoding ACE is located on the long arm of chromosome 17 (17q23) and is 21 kb long, including 26 exons and 25 introns. The structure of ACE may be the result of an ancient gene duplication that occurred approximately 700 million years ago. The main function of ACE is the conversion of AngI to the vasoconstrictor AngII, which is the main active product. In addition, ACE metabolizes bradykinin, which is a potent vasodilator. ACE is involved in the metabolism of other angiotensins, in particular Ang(1–7), forming, together with ACE 2 and other components of the renin-angiotensin-aldosterone system (RAAS), a complex balanced system for maintaining blood pressure, water and electrolyte balance, and many other components  of systemic, tissue and cellular homeostasis that have not yet been fully studied. More data are accumulating confirming the role of ACE for the renal development, early hematopoiesis, normal male fertility, erythropoiesis, myelopoiesis. ACE plays important roles in the immune response, intracellular signaling.

The study was conducted to assess the effect of mulberry leaves extract (Morus alba) on the growth rate of giant freshwater prawn, Macrobrachium rosenbergii. In the present study, the mulberry leaves extract was mixed with commercial pellets using the spray method; pellets with 5 % and 10 % mulberry leaves extract. Meanwhile, the control treatment was a commercial pellet with no mulberry leaves extract. M. rosenbergii were fed with the experimental pellets for 30 days and each treatment had 10 tails of M. rosenbergii juveniles. The result showed that the juveniles fed with pellet with 10 % mulberry leaves extract had the highest survival rate and the total number of moulting. As a conclusion, the mulberry leaves demonstrated a good effect on the growth of M. rosenbergii and reduced the mortality rate, thus, the present study suggests the use of mulberry extract as a potential nutrient supplement in the feed to increase the production of M. rosenbergii post-larvae.

Chevon (goat meat) is most popular meat of ruminant species and is accepted by all communities in India. Its keeping has been a traditional activity in India and a primary source of livelihood for people below the poverty line. Goats have a number of characteristics, such as high reproductive potential, ability to thrive on shrubs, bushes, and tree leaves, and less susceptibility to infectious diseases, that make them suitable as meat producing livestock in developing countries, Raghavan [1] opined chevon is obtained from goat of different genotypes like Black Bengal, Jamunapuri, Ganjam, Sirohi, Beetal etc. in India.

(ITS) have become an important research area. Vehicle make and model recognition is one of the topics in the domain of ITS for secure access and traffic monitoring applications. This paper presents an effective approach for fast recognition of vehicle make and model form back views. We use efficient hierarchical classifier that determine the class of vehicle at first and then recognize vehicle make and model in a smaller group which dramatically increases the speed and performance of the method by focusing attention on the most discriminative regions. In this method, different classes are defined based on the location of license plate and taillights of vehicle. By considering the vehicle initial class, we can select different regions and features for different classes in recognition step that improve the results. Results confirm our prediction that hierarchical classification is more powerful in vehicle model recognition. The final system is capable of recognition rates of 96% on a dataset of over 280 back view images of vehicles. The proposed algorithm is robust to illumination and weather conditions.


An instrument for measuring viscosity coefficient of liquid is developed.A taper magnet is used to hold and release the steel ball,and then the steel ball can fall along the cylinder's axis.A bar magnet is used to pick up the falling steel ball and make the steel ball be reused without washing.A measuring cylinder is also specially designed to contain the measured liquid.The starting timing-position of the terminal velocity of the steel ball is theoretically analyzed,and tts numerical calculation is performed by the use of MATLAB software. The experimental results show that this instrument has advantages of high accuracy,no oil-pollution and simple operation.


A multistaged combustion burner design is being evaluated on a 0.6 MW package boiler simulator for in-furnace NOx control and high combustion efficiency. A low NOx precombustion chamber burner has been reduced in size by approximately a factor of two (from a 600 ms first-stage residence time to 250 ms), and, for additional NOx control, coupled with [1] air staging, resulting in a three-stage configuration, and [2] natural gas fuel staging, yielding up to four stoichiometric zones. Natural gas, doped with ammonia to yield a 5.8 percent fuel nitrogen content, was used to simulate a high nitrogen content fuel/waste mixture. In low NOx burner baseline tests, without advanced staging, a 315 ppm NO emission (measured dry, corrected to zero percent O2) was measured, compared with an emission of 1000 ppm measured using a conventional, unstaged burner. Both of the multistaged combustion modifications for additional NOx control reduced NO emissions by an additional 50 percent, to 160 ppm meeting the program goal. However, air staging application resulted in the entire front end of the boiler being fuel-rich, whereas fuel staging, or reburning, in the boiler required only a small fuel-rich flame core in the boiler. Further, no boiler penetrations were necessary with reburning modification, as staged fuel and air were injected through the boiler front wall; access for burnout air injection deep into the boiler was necessary for the air staging modification. Thus, the four-stage configuration, combining the precombustion chamber burner and reburning, appears to be the most promising approach for minimizing NO emissions and maximizing primary fuel/waste destruction.


Phishing is a form of cybersecurity threat where the criminal tries to gain access to users personal information by infecting their system using malware and viruses. Appearing to come from legitimate sources, it is very easy to fall in the phishing scam. As each phishing data contains features that are consistently different from another, using a predefined set of rules makes a system useless. Data mining techniques can be applied to collected network traffic and build models to predict future attacks. However, since most of the data packets are legitimate, the model tends to produce a bias towards positive results in this imbalanced dataset. In this study, we investigate how prediction accuracy varies in a balanced dataset against an imbalanced one. SMOTE is applied to balance the dataset. XGBoost, Random Forest and Support Vector Machines have been applied on the phishing dataset. Results show much higher accuracy rates with SMOTE application. The highest jump in accuracy has been recorded in XGBoost from 89.87% to 97.17% showing that SMOTE is an effective tool in phishing data monitoring.


Condyloma acuminatum is a benign epithelial tumor caused by human papillomavirus(HPV) infection.Sexual contact is one of the main modes of transmission.There is currently neither ideal therapy nor technology for its treatment.Traditional laser,freezing and other invasive treatment bring suffering and high recurrence rate to the patient,and can not act on some of the special parts.Photodynamic therapy is a new ablation technique and was officially included in the STD treatment guidelines developed by the U.S.Centers for Disease Control and Prevention(CDC) in 2009.5-aminolevulinic acid photodynamic therapy for condyloma acuminatum has gained widespread recognition in recent years.Advances of photodynamic therapy in the treatment of condyloma acuminata will be reviewed in this paper.


The possibility of using softwood distillate as a bio-based additive or filler in wood-plastic composites (WPCs) was studied by adding various amounts (1–20 wt%) of distillate to a commercial WPC consisting of thermally treated sawdust in a polypropylene (PP) matrix. Softwood distillate was obtained as a secondary product from industrial ThermoWood® processing and it was further processed in the laboratory. The addition of softwood distillate significantly enhanced the mechanical properties of WPC when the distillate content was 2 wt%; tensile strength increased by 5%, tensile modulus by 3%, flexural strength by 3%, and modulus of elasticity by almost 2% compared with the unmodified WPC. In addition, a considerable decrease (over 16%) in water absorption was observed on distillate addition. Proton-transfer-reaction time-of-flight mass-spectrometry (PTR-TOF-MS) analyses revealed that the addition of softwood distillate increased release rates of volatile organic compounds (VOCs) in general, and that the odor of acetaldehyde and guaiacol is detectable in several WPCs. Overall, softwood distillate had positive effects on this particular WPC.

It is estimated that one of four ischemic strokes are noticed upon awakening and are not candidates for intravenous recombinant tissue plasminogen activator (rtPA) because their symptoms are >3 hours from last seen normal (LSN). We tested the safety of rtPA in a multicenter, single‐arm, prospective, open‐label study (NCT01183533) in patients with wake‐up stroke (WUS).


DISCOURAGING feature of electrocardioA graphic (ECG) monitoring in the operating room is the time-consuming nuisance of attaching electrodes and weaving cables under and around the patient to the recorder, all the while trying to induce or maintain anesthesia.1 Occasional comments decrying the use of any monitoring other than "the five senses" may well stem from a lack of daiIy familiarity with the ECG, due to the admittedly tedious task of making proper connections to the patients by the physician in a busy practice. Certainly, no one advocates replacing any of these five senses by the ECG, but much additional information is avaiIable to the anesthesiologist who has gained this daily familiarity with the relationship of the electrical sensitivity of the heart to the varying conditions of anesthesia and surgery.2--"


:  In the present study, the relationship of ovarian development and marsupial development to the female molt cycle was examined in Acanthomysis robusta (Crustacea: Mysida). Yolk accumulation in ovaries started at stage C and advanced during stages D0–D2 of the female molt cycle. As females at stages A–B exhibited newly spawned eggs in their marsupia and non-developed ovaries, oviposition likely occurred at stage A of the molt cycle. Larvae in the marsupia were at the egg-shaped embryonic stage during the female molt stages A–C. Larval hatching occurred at stage C, and the larvae were at the nauplioid stage during stages C–D1 of the female molt cycle. Larvae at the postnauplioid phase appeared at stage D1, indicating that naupliar molting occurred in stages D0–D1 of the female molt cycle. At stage D2, empty marsupia were observed, and any remaining brood were at the postnauplioid phase, suggesting that young are released at stage D2 of the female molt cycle. The brood size (8–53 embryos and larvae) was significantly correlated to female carapace length. These results indicate that ovarian development and marsupial development are closely related to the female molt cycle of A. robusta.

This engineering evaluation was conducted to evaluate vitrification technologies for remediation of raffinate sludges, quarry refuse, and contaminated soils at the Weldon Spring site in St. Charles County, Missouri. Two technologies were evaluated: in situ vitrification (ISV) and the joule-heated ceramic melter (JHCM). Both technologies would be effective at the Weldon Spring site. For ISV, there are two processing options for each type of waste: vitrify the waste in place, or move the waste to a staging area and then vitrify. The total time required to vitrify raffinate sludges, quarry refuse, and contaminated soil is estimated at 5 to 6 years, with operating costs of $65.7M for staged operations or $110M for in-place treatment. This estimate does not include costs for excavation and transportation of wastes to the staging location. Additional tests are recommended to provide a more in-depth evaluation of the processing options and costs. For the JHCM process, about 6.5 years would be required to vitrify the three waste types. Total operating costs are estimated to be $73M if the glass is produced in granular form, and $97M if the glass is cast into canisters. Costs for the excavation and transportation of wastes are beyond the scope ofmore » this study and are not included in the estimates. Additional tests are also recommended to better define technical issues and costs. 10 refs., 2 figs., 5 tabs.« less


In this paper we have introduced a new parametric output feedback control design algorithm based on the Block similarity transformations. It is needed that complete Block controllability and Block observability be a necessary and sufficient conditions for the proposed method in order to assign whole set of poles via the output feedback for linear multivariable system. The parameterization of the output feedback leads to the solution of nonlinear system of equations, for the demonstration of the proposed method efficiency a numerical example of gas turbine model is illustrated.


The Impact Echo [I-E] is very good known method of NDT, e.g. [1] etc. It is used in two basic ways. First, it is evaluated echo time from the damage as classical ultrasound NDT. The second way uses impact pulse as a simple wide-spectrum excitation for spectral analysis. The obtained resonance frequency components correspond to dimensions of the tested body. Frequencies of these components are compared with standard forms and their deviations signalize non-idealities and defects. This NDT method is very cheap and effective especially for small bodies with expressive resonance properties. On the other hand this method has a small sensitivity to relatively small cracks. But this method doesn't use the same principle as the good known crack detection by human hearing as this one needn't standard forms for comparison. The new method [4] consists in utilize of nonlinear acoustic properties of bodies with cracks (good known as SIMONRUS, RAS, [2], [3] etc.) when the resonance frequencies depend on excitation. Therefore the customary use of Fourier Transformation to whole recorded sound of I-E brings inconvenient averaging of this effect with the main part of the recording time when the intensity of excitation is low. The main idea of the new variant of the spectral I-E method consists on searching of time dependency of frequencies of the dominant resonance frequency components as dependence of excitation. Some aspects of time-frequency analysis of I-E signals are also shown in [4]. On the other hand, the complex analysis of full I-E signal is very complicated because there are tens of dominant harmonic components. Therefore the analysis of soft frequency deviations in time dependencies is very elaborate. Further our experiments show that there is more information about behavior of tested specimens as magnitude dependencies of individual harmonic components. For this reason we designed a program for detailed time-frequency analysis of I-E signals. It has these features: − time-frequency spectral analysis with possibilities of setting of various parameters (as length of time segments, length of time shifts etc.); − automatic detection of peaks (1 st or 2 nd derivation) and separation of individual dependencies; − 3D image (2D+color) of detected dominant harmonic components and their time dependencies; − possibility of separate zoomed displaying of time dependency of frequency and magnitude of each selected component. By this way the detailed analysis of I-E signals of specimens with nonlinear effects can be advanced and more information about flaw of tested specimens can be acquired from I-E signal. The experimental findings will enable to prepare practical variant of the program in next step.


This paper introduced the processing of the domestic and international livestock wastewater. The actuality of environmental problems caused by livestock husbandry was discussed and the relationship between husbandry and sustainable development was remarked on. From the point of ecosystem, dealing with livestock wastewater harmlessly with bio-filtration system is advised. A bio-filtration system is set up based on the analysis of a typical and simple water treatment system. The system mainly consists of a solid removal basin and a planting filter. We elect ryegrass as the planting-filter, because it gets best sod, mechanic filtration and bio-filtration. Effects of static bio-filtration were studied in ryegrass. Under this system, to achieve preferable purification efficiency, the wastewater concentration and the area of planting which suited for pasture growth will be provided. Near infrared spectra was used to analyze the water quality, about chemical oxygen demand (CODcr). A set of 20 samples of livestock wastewater with different concentrations was taken from the Animal Institution of Zhejiang Agricultural Science Organization, and the partial least square (PLS) was used to develop predictive models. To validate these models, some samples were used. SEP were 22, 32 and r2 values using the validation set of data were 0.9895, 0.9985 for COD of wastewater.


In this paper, we present a method for model synthesis. Based on observations of running system, a model that can describe the observed behavior is automatically generated.

The models can be used for impact analysis, verification, documentation etc. The method has been implemented; we describe that implementation and present an evaluation of its performance, the conclusion of the evaluation is in favor of the proposed method.


Long term and strenuous exercise training can be responsible for the disorder of iron metabolism, which induces the formation of iron deficiency in the body. It is also the important reason for the occurrence of sports anemia. The disorder of iron metabolism because of iron deficiency induced by exercise relates to the decrease of iron absorption, deficiency of iron intake, increase of iron lose, irrational dietetic habit, hemolysis and stress of the body. The indexes reflecting the iron metabolism of the body were studied. The changes of serum iron, serum ferritin, transferritin level and other indexes are able to reflect the status of iron metabolism of the body to a certain extent and they are applied in exercise to inspect the status of iron change and observe the effects of iron preparation administration in the athletes. During exercise the supplement of iron preparation has a certain effect on the prevention of iron deficiency, but the indexes were not very well combined with the application effects, so they were of poor pertinence.


This paper presents an improved VLSI architecture of S-box for AES encryption system. Certain basic blocks in conventional architecture are replaced by efficient multiplexers and an optimized combinational logic to facilitate speed improvement. The proposed as well as conventional architecture are implemented in Xilinx FPGA and 0.18 μm standard cell ASIC technology. ASIC implementation indicates speed enhancement while maintaining constant area compared to conventional architecture. FPGA implementation also confirms speed improvement of about 0.6 ns along with low utilization of FPGA fabrics. Furthermore, there is significant power improvement (155 %) compared to conventional structure.


Presence and copresence have been key goals of researchers and developers of shared virtual environments. Much research has assumed that the two reinforce each other; that is, an enhanced sense of presence enhances copresence and vice versa. In this essay we question this assumption, and provide some examples in which users experience high presence and low copresence and the opposite. Although the results are qualitative, we argue that it is worth pursuing the situations in which there seems to be a trade-off between the two, since this will have implications for design and for the future uses of shared virtual environments generally.


COVID-19 affects firstly the respiratory system of patients however cardiovascular system is also damaged. To study the impact of a novel coronavirus infection on the cardiovascular system, in particular on echocardiographic parameters after SARS-CoV-2 is very important.

 To compare echocardiographic parameters in patients with COVID-19 pneumonia in hospital and 3 months after hospital discharge.

 A total of 106 patients with confirmed COVID-19 pneumonia were included in the period from April to July 2020 within "One-year Cardiac Follow-up of COVID-19 Pneumonia". All patients underwent clinical examination including transthoracic echocardiography in hospital and 3 months ± 2 weeks after discharge. Mean age of patients was 47±16 years (19–84 years), mean body mass index was 28.2±5.7 kg/m2, females were 49%. During hospitalization, chest computed tomography detected mild lesions in 29.2%, moderate lesions in 31.1%, severe lesions in 27.4% and critical lesions in 5.7%. Cardiovascular pathology detected in 52% of patients.

 Three months after discharge significant dynamics of mean echocardiographic parameters was observed. Left ventricular end-diastolic, end-systolic and stroke volume decreased (113.8±26.8 vs 93.5±29.4 ml; 37.7±13.0 vs 31.3±14.2 ml; 77.2±17.8 vs 62.2±18.7 ml, respectively; all p<0.001). End-diastolic right ventricular outflow tract diameter, pulmonary artery trunk diameter decreased (26.0 [24.0–9.3] vs 25.0 [23.0–27.0] mm, p=0.004; 21.7±3.6 vs 18.7±2.5 mm, p<0.001), as well as pulmonary artery systolic pressure (28.0 [25.0–32.25] vs 21.5 [17.0–25.0] mmHg) and rate of moderate to severe tricuspid regurgitation (52.4 vs 19.8%, both p<0.001). Right atrium volume (42.0 [37.0–50.0] vs 31.0 [22.0–36.5] ml, p<0.001) and width decreased (36.1±4.6 vs 34.5±6.5 mm, p=0.023), however right atrium length increased (46.7±6.8 vs 48.6±7.1, p=0.021).

 In patients after COVID-19 pneumonia echocardiography showed decrease of the load predominantly on the right heart 3 months after discharge. A subgroup analysis is planned depending on the severity of lung damage and presence of cardiovascular pathology.

An integrated radar and ultrasound sensor, capable of remotely detecting and imaging concealed weapons, is being developed. A modified frequency-agile, mine-detection radar is intended to specify with high probability of detection at ranges of 1 to 10 m which individuals in a moving crowd may be concealing metallic or nonmetallic weapons. Within about 1 to 5 m, the active ultrasound sensor is intended to enable a user to identify a concealed weapon on a moving person with low false-detection rate, achieved through a real-time centimeter-resolution image of the weapon. The goal for sensor fusion is to have the radar acquire concealed weapons at long ranges and seamlessly hand over tracking data to the ultrasound sensor for high-resolution imaging on a video monitor. We have demonstrated centimeter-resolution ultrasound images of metallic and non-metallic weapons concealed on a human at ranges over 1 m. Processing of the ultrasound images includes filters for noise, frequency, brightness, and contrast. A frequency-agile radar has been developed by JAYCOR under the U.S. Army Advanced Mine Detection Radar Program. The signature of an armed person, detected by this radar, differs appreciably from that of the same person unarmed.
