Within a modest neighbourhood, some mothers develop strategies to take on their roles in a context of precariousness. Unemployment and instability of couples lead them to declare themselves as living alone with their children in order to perceive the related social security benefits. They give their family name to their children, provide them with a roof and receive regular financial allowances. In this context, what is the husband's status for these women who take on all parental functions ? The observation of the course of a typical day highlights their inscription in the social networks, their capacity to assume their duty as mothers but also the contradictions with which they have to struggle.


The paper summarizes the findings of a series of studies of SiC whisker-reinforced alumina composites emphasizing the properties of these composites and the influence of composition and microstructure. First, both the steady-state toughness and the R-curve response increase with whisker content and diameter. The room temperature flexure strength of aluminas with different grain sizes also increases with whisker content. Furthermore, the resistance to slow crack growth under both montonic and cyclic loading is substantially improved by whisker reinforcement in comparison to that of alumina and other ceramics. The thermal conductivity and electrical resistivity exhibit a substantial increase and decrease, respectively, with whisker loadings above 10 vol.%. The thermal expansion coefficients decrease in a systematic fashion with increase in whisker content. However, the expansion coefficients are greater in the direction parallel to the hot pressing axis as compared to the perpendicular direction due to internal stresses and the preferred orientation of whiskers. The changes in mechanical and thermal properties due to SiC whisker additions result in substantial improvement in thermal shock resistance for samples of various sizes. At elevated temperatures, tests in air show that improvements in strength and resistance to strength degradation are associated with SiC whisker reinforcement. The limitingmore » factors in elevated temperature mechanical response of the composite at 1200{degrees}C and above are related to surface oxidation-reaction processes and creep. On the other hand, the creep resistance of the composite is far greater than alumina with a similar fine grain size at temperatures {ge} 1200{degrees}C. Futhermore by increasing the grain size of the alumina matrix, the creep resistance of the composite can be substantially increased.« less


Impressive advances are being made in the field of display metrology, as illustrated in standards such as the Video Electronics Standards Association's Flat Panel Display Measurement standard. However, issues remain regarding the technology-dependent response of display to large-scale signal eros such as noise-induced errors on the data and control lines. The NIST Display Interface Testbed can be used in conjunction with a graphics controller, test generator, or other standard signal source, to inject a user-specified controlled sequence of errors into the interface of a display under test, permitting observation and measurement of the response of the display. In addition to its function as an interface tester, the Testbed effectively serves as a non-intrusive probe into the operation of the display. the programmed control structure of the Testbed permits the convenience of automated test sequences. Development of a feedback mechanisms which allows the test stimulus to be modified in real time, as a function of measurement result and user commands is planned for 1999.

In this paper, we develop a model for on-demand telemedicine platform operations that focuses on managing multi-specialty, online-based care in the presence of general and specialized care demand interactions, as well as multiple physician classes. Although this type of demand interaction is common in practice, its impact on platform and physician decisions has not received sufficient attention in the operations literature. Our paper provides guidance on managing multi-specialty telemedicine platforms. We formulate a queueing model of online service with multiple interacting demand and supply types. In our model, the platform sets patient fees and physician compensation levels, and physicians, anticipating equilibrium patient demand response, can decide whether to join the platform and how much of their capacity to allocate to each type of care (i.e., general and specialized care) on the platform. We derive closed-form expressions for the optimal physician and platform policies in the presence of demand interaction between the general and specialist demand streams. In particular, we find that the optimal capacity allocation decision for physicians of a particular type and class is to either only serve general patients or only serve specialized care patients. Moreover, for moderately compensated specialists, the demand interaction between the general and specialist care lowers the barrier for specialists to join the platform and the benefits of demand interaction substitute for specialist compensation levels. In addition, the benefits of demand interaction subside as specialist compensation levels increase. Finally, we provide a closed-form description of the profit loss stemming from the platform ignoring the demand interaction effects. Specifically, this profit loss increases with the general patients' valuation of specialized care and the specialized care patients' sensitivity to delays, and decreases with the specialists' opportunity costs. Our analysis describes the optimal management policies for on-demand multi-specialty telemedicine platforms, providing a foundation for studying the role of telemedicine platforms within broader patient-centric healthcare ecosystems.


Insufficient calcium supply may cause deficient mineralization of the skeleton. Calcium overload may be associated with severe vascular morbidity and soft-tissue calcifications. It is suggested the total oral and/or enteral calcium intake from nutritional sources and phosphate binders be in the range of 100%–200% of the DRI for calcium for age (R 7.1.1). To avoid the critical accumulation of calcium, oligoanuric children on dialysis therapy may require a further reduction in total oral and enteral calcium intake from nutritional sources and phosphate binders. Vitamin D Recent clinical evidence suggests a high prevalence of vitamin D insufficiency in children with CKD. Reasons for the high prevalence of low vitamin D levels in patients with CKD include: – Sedentary lifestyle with reduced exposure to sunlight – Limited ingestion of foods rich in vitamin D – Reduced endogenous synthesis of vitamin D 3 in the skin of patients with uremia – Urinary losses of 25(OH)D and vitamin D–binding protein in nephrotic patients Measure serum 25-hydroxyvitamin D levels once per year in children with CKD (R 7.2.1). Supplementation with vitamin D 2 (ergocalciferol) or vitamin D 3 (cholecalciferol) is suggested if the serum level of 25-hydroxyvitamin D is less than 30 ng/mL (75 nmol/L) (R 7.2.2). In the repletion phase, it is suggested that serum levels of corrected total calcium and phosphorus be measured at 1 month following initiation or change in dose of vitamin D and at least every 3 months thereafter (R 7.2.3). When patients are replete with vitamin D, it is suggested to supplement vitamin D continuously and to monitor serum levels of 25-hydroxyvitamin D yearly (R 7.2.4). Methods to improve low oral and/or enteral calcium intake and absorption include: • Increased consumption of calcum-rich and/or calcium fortified foods or tube feedings • Supplementation with calcium containing pharmacological agents between meals or bolus tube feedings • Use of calcium-containing phosphorus binders for managing hyperphosphatemia • Supplementation with vitamin D Abbreviations: ACEI Angiotensin-converting enzyme inhibitor AMDR Acceptable macronutrient distribution ranges ARB Angiotensin-receptor blocker BMI Body mass index CDC Centers for Disease Control and Prevention CHD Coronary heart disease CKD Chronic kidney disease D Dialysis DRI Dietary reference intake DV Daily value EER Estimated energy requirement HD Hemodialysis IDPN Intradialytic parenteral nutrition nPCR Normalized protein catabolic rate NSAID Nonsteroidal anti-inflammatory drugs PAL Physical activity level PD Peritoneal dialysis PTH Parathyroid hormone R Recommendation rhGH Recombinant human growth hormone SDS Standard deviation score UL …


Careful organization of research and development (R&D) is the key to transformative innovation. Among US federal R&D programs, the Defense Advanced Research Projects Agency (DARPA), the Advanced Research Projects Agency for Energy (ARPA-E), and the Advanced Technology Program (ATP) were designed to empower groups of people to tackle complex problems and realize broad societal benefits. This article offers a taxonomy of heuristics that guide the work of these three agencies, grounded in qualitative accounts of management practices. At the heart of each agency is the duality of isolation and interaction, or 'Island' and 'Bridge'. The Island clusters heuristics that isolate R&D programs from the concerns of operations (as well as those of basic research). The Bridge clusters heuristics that connects R&D to broader institutional contexts. Island + Bridge is a framework for understanding a range of practices at organizations that aim to create radical change.


The purpose of this study is to analyze the urban spacial characteristics according to the parcel transformation by establishing the parcel information system. In order to achieve the objective of this study, parcel, roads and constructions have been chosen as factors to structure the urban spacial characteristics. On top of that, parcel according to this study is a basic unit in registering and notifying the land and also includes diverse data on cadastral record, land category, border, size, owner and price of land etc, as a basic unit. On the other hand, the land use characteristics have been analysed by establishing the parcel information system based on the MGE 7.0 GIS software of Intergraph in terms of case analysis. With regard to the feature of the transformation of parcel analysed, partition and annexation of parcel are most commonly executed. Concerning partition of parcel by year, number of partition of parcel has been increased as times pass by but retained the status quo later to decreased eventually. In the meantime, as far as integration is concerned, number of integration has been rapidly grown at certain point. Having considered aforementioned result of study, it is concluded that parcel is considerably important factor in the sense that it creates space of urban and provides mechanism of development. It is forecast that analysis of urban spacial based on parcel information system will be effectively applied to planning and analysing space of the urban including plan of the readjustment of urban and the analysis of location etc.


For homopolysaccharides in which the glycosidic oxygen is equatorial to both sugar rings, computer model building suggests that linkage positions have the following stereochemical and biological significance: 1,4-linkages lead to stiff ribbon-like chains; 1,3-linkages to stiff helices likely to combine in multiply stranded ropes; 1,6-linkages form loosely jointed chains with high flexibility and solubility; 1,2-linkages lead to stiff contorted chains unlikely to form stable tertiary structures.


This paper mainly concentrates on the design and implementation of ternary logic circuits. The ternary numeral system has its base as 3. Ternary logic will use three symbols, which are, 0,1 and 2. The ternary logic has significant merits over binary logic in designing digital circuits. In this paper, it is proposed to implement a half adder circuit using ternary 3 to 1 multiplexer. The main objective of the work is, to design and implement ternary logic circuits and to analyse the function of the ternary combinational circuits using mentor graphics tool in 90nm technology. This paper also compares the ternary half adder design using k-map method with the proposed ternary half adder using multiplexer in terms of power dissipation, propagation delay and transistor count.


In this paper, we present virtual embedded views used for turnbased pedestrian navigation in Augmented Reality (AR). Embedded views allow users to see around occluding structures and at the same time seamlessly integrate the augmented navigation aid into the otherwise occluded view. Users get a preview on upcoming route changes, without the need to consult an additional map view. We compare embedded views to other methods revealing the occluded navigation aids. We demonstrate that the technique is more screen-space efficient when compared to a typical x-ray vision technique, and may better facilitate the mental linking of information, when compared to a mirror.


The preference for decentralization in the classic debates about planned production in a socialist economy has appeared more recently in the context of an organization that maximizes, subject to constraints, a scalar-valued function of its decisions. This article seeks a basis for the preference. A class of schemes for organizational decision-making is defined, and decentralized (in the classic sense), centralized, and unrestricted subclasses are considered. Criteria for ranking the schemes are obtained and applied in a simple illustrative organization. It is found that a general preference for one of the subclasses cannot be defended without further restricting the model substantially. THIS PAPER concerns an economic organization which is an abstraction from the profit-maximizing firm. It concerns the problem which confronts the organization when it must choose among alternative schemes, exhibiting varying "degrees" of centralization, for sharing among its members the task of regularly revising its decisions in the face of a changing environment. 1. BACKGROUND OF THE PROBLEM Some of the major issues involved in this choice appeared originally in the old economic debate about decentralized versus centralized planning in a socialist state. Recently these issues seem to have been revived in the different context of the organizations which concern us here. Several decentralized schemes have recently been shown to approach optimal decisions in such organizations, and it has been regarded as promising that they are in some important respects analogous to the decentralized schemes which were the final fruit of the debates of "socialist economics." The outcome of the debate about the centralized control of a socialist economy, which started with Barone [4], gained momentum with Hayek [9] and von Mises [10], and petered out after Lange [13] and Lerner [14],2 was as follows: virtually all participants3 agreed that there exists only one feasible mechanism for solving the "millions of equations in millions of unknowns" required to find a Pareto Optimum (in which no one's consumption of any commodity can be increased without decreasing someone's 1 This paper is based on [16], a longer study. For guidance in the original study the


In order to optimize the nutrient formulations of floating system,the effects of different nutrient solutions on growth and agronomic characteristics of flue-cured tobacco seedlings in the floating system by sand culture were studied with Yunyan 85 coated seeds as material.The results showed that compared with CK,the growth of tobacco seedlings under T3 treatment was faster,moving up the time of seedling formation by about 2 days,and the seedling-forming rate reached 96.4%.The difference of seedling-forming rate of T3 treatment reached extremely significant level among all the treatments in this experiment.Both fresh weight and dry weight of above-ground parts and under-ground parts of plants under T3 treatment were higher than CK and those under other treatments.In the seedling-forming stage,stem height,stem diameter,maximum leaf length and leaf width of T3 treatment were increased by 0.8%,3.2%,2.9% and 7.1% respectively in comparison with CK.So the nutrient formulations of T3 were suited for tobacco to be used in floating system by sand culture.


The study was conducted in the spring semester of the 2018-2019 academic year with the aim of evaluating the communication skills and the factors affecting the communication skills development in the 1 st and 4 th grade students of the university. Data were collected using "Personal Information Form" and "Communication Skills Assessment Scale". 1. The mean scores of the classes were 101.2 ± 1.286 and 98.8 ± 1.414, respectively. In the whole sample, the SANS score ranged between 68 and 123, with a mean of 100.2 ± .956.The communication skills of female students were found to be significantly higher than the male students. The variables such as age, type, mother education, father education and place of residence were found to be ineffective on communication skills.


We prove the strong consistency and the asymptotic normality of the maximum likelihood estimator of the parameters of a general conditionally heteroscedastic model with $\alpha$-stable innovations. Then, we relax the assumptions and only suppose that the innovation process converges in distribution toward a stable process. Using a pseudo maximum likelihood estimator with a stable density, we also obtain the strong consistency and the asymptotic normality of the estimator. This framework seems relevant for financial data exhibiting heavy tails. We apply this method to several financial index and compute stable Value-at-Risk.


To develop a new spin-crossover functional material, a magnetic hybrid compound [Fe(qsal)2][Ni(mnt)2] was designed and synthesized (Hqsal = N-(8-quinolyl)salicylaldimine, mnt = maleonitriledithiolate). The temperature dependence of magnetic susceptibility suggested the coexistence of the high-spin (HS) Fe(III) cation and π-radical anion at room temperature and a magnetic transition below 100 K. The thermal variation of crystal structures revealed that strong π-stacking interaction between the π-ligand in the [Fe(qsal)2] cation and [Ni(mnt)2] anion induced the distortion of an Fe(III) coordination structure and the suppression of a dimerization of the [Ni(mnt)2] anion. Transfer integral calculations indicated that the magnetic transition below 100 K originated from a spin-singlet formation transformation in the [Ni(mnt)2] dimer. The magnetic relaxation of Mossbauer spectra and large thermal variation of a g-value in electron paramagnetic resonance spectra below the magnetic transition temperature implied the existence of a magnetic correlation between d-spin and π-spin.


Background and objective: This study investigates the physical factors that determine the top ranker players based on the Greco-Roman wrestlers in the national athletic team of South Korea. Additionally, the study developed a prediction model using physical factors. For this analysis, the data of 163 players in the last 20 years (1999–2018) available on the Athletic Competition Performance Assessment Computer System were used. A top ranker was defined as an athlete who had won a medal in a world championship or the Olympic Games.Methods: The logit model was used as the model and the estimations were performed using maximum likelihood estimation (MLE) with E-views9.5 (Lightstone Corp., Tokyo, Japan). The estimation results demonstrated that the probability of becoming a top ranker increased with the following: increase in the length of the career compared to age, increase in the distance of standing long jumps, decrease in response time to light, and increase in bench press weight.Results: The analysis of the model's estimation results showed that superior results were produced when the standing long jumps, response time to light, and bench press weight were normalized using the weight class based on McFadden R2, Akaike Information Criterion (AIC), and Schwarz information criterion (SBIC) as compared to when they were normalized using the height and body weight. Conclusion: The estimation model established in this study for the significant physical strength factors shown in the South Korean top rankers is expected to be used as important data for predicting and fostering world-class South Korean Greco-Roman wrestlers.


The article analyses a problem of the constitutional right of citizens of the Russian Federation for the free medical care.

Particular attention is drawn to the legal basis of the right to free health care.


Long-term climate data records about aerosols are needed in order to improve understanding of air quality, radiative forcing, and for many other applications. The Sea-viewing Wide Field-of-view Sensor (SeaWiFS) provides a global well-calibrated 13- year (1997-2010) record of top-of-atmosphere radiance, suitable for use in retrieval of atmospheric aerosol optical depth (AOD). Recently, global aerosol products derived from SeaWiFS with Deep Blue algorithm (SWDB) have become available for the entire mission, as part of the NASA Making Earth Science data records for Use in Research for Earth Science (MEaSUREs) program. The latest Deep Blue algorithm retrieves aerosol properties not only over bright desert surfaces, but also vegetated surfaces, oceans, and inland water bodies. Comparisons with AERONET observations have shown that the data are suitable for quantitative scientific use [1],[2]. The resolution of Level 2 pixels is 13.5x13.5 km2 at the center of the swath. Level 3 daily and monthly data are composed by using best quality level 2 pixels at resolution of both 0.5ox0.5o and 1.0ox1.0o. Focusing on the southwest Asia region, this presentation shows seasonal variations of AOD, and the result of comparisons of 5-years (2003- 2007) of AOD from SWDB (Version 3) and MODIS Aqua (Version 5.1) for Dark Target (MYD-DT) and Deep Blue (MYD-DB) algorithms.


Knowledge of dietary habits and related factors is critical to the development of workable nutrition intervention programs. A survey of 5th, 8th and 11th grade Taipei school children gathered data on the following variables: food intake, eating patterns, behavior, and demographics. The relationships among these variables are shown by statistical analysis of the data. Significant associations were found between sociodemographics and food frequencies, behavior and food frequencies, and eating patterns and sociodemographics. Sociodemographic factors yielded the most significant relationship to food frequencies, a possible indication of the increasing wealth of Taipei citizens. The results suggest a shift away from traditional Chinese foods. The implications of these changing food habits are discussed.


Existing passive microwave radiometers that are used for ocean observations are limited in spatial resolution and geographic coverage, due to the limitations of traditional antenna technologies using mechanically-scanning reflectors and horn-type feeds. Future ocean observation missions call for new solutions, such as digitally-beamforming array feeds (DBAFs) as well as stationary and more complex reflectors. Our studies demonstrate that DBAFs can overcome the physically fundamental limitations of traditional horn feeds, and are capable of meeting all the challenging requirements for the next-generation instruments.


We develop a North/South growth model to investigate the normative question of international transfers to preserve tropical forests. The South converts forest lands into agricultural lands to produce a nal consumption good which is consumed by the North. We consider two ways of incorporating the externality coming from deforestation in the utility of the North: i) through an amenity value, which re ects a continuous willingness to preserve forests, or ii) through a minimum stock of tropical forests to be preserved. First, we solve the optimal program and we characterize the dynamic properties of the optimal deforestation regime. Second, we derive the decentralized equilibrium outcome in which the externality can be corrected by a transfer scheme from the North to the South. This transfer function depends both on the stock of forest (positively) and on the deforestation rate (negatively). Third, we characterize the dynamic implementation rule which must be satis ed by this transfer to restore the optimum. Finally, we analyze the speci c cases of a pure forest subsidy policy and a pure deforestation taxation policy and we illustrate these ndings with an analytical speci ed model.


The Belgian Law concerning grave breaches of humanitarian law was meant to implement the international legal obligation to render genocide, war crimes and crimes against humanity punishable and to prosecute the perpetrators of such acts irrespective of the nationality of the perpetrator, the nationality of the victim, the place where the crime was committed or the time when the crime was committed.


The question of pattern in architecture generally divides architects into two distinct groups: those with an aesthetic interest in man-made ornament; and those who take a deeper interest in the processes that underlie the formation of pattern in the natural world. An investigation of the performative, though, enables an exploration of pattern that arises out of the interaction of man-made interventions with the natural environment. Michael Hensel, Professor for research by Design at AHO, the Oslo School of Architecture and Design, and Achim Menges of the Emtech (Emergent Technologies and Design programme) at the Architectural Association in London, explore this arena based on their research and educational work at the AA and other international institutions, which focuses on aspects of performance in the built environment.

Eggs of Schistosoma mansoni and S. japonicum were hatched in vitro and behavioral changes and shedding of cilia of miracidia observed in solutions of different osmolarities and ionic content. Cessation of swimming occurred in solutions of osmolarities similar to or higher than that of Biomphalaria hemolymph. Shedding of cilia was observed only in media suitable for continued development. Variation in size and nuclear content of miracidia of S. mansoni and S. japonicum was studied. Organisms grown in axenic and monoxenic cultures shed their cilia, doubled in body size, and showed increases in numbers of large nuclei, with loss of terebratorium, and dedifferentiation of the nervous system. Differences in the behavior in vitro of Schistosoma mansoni and S. japonicum are discussed. Little is known about the specific factors which promote larval development of human schistosomes in the snail host. Studies by Targett (1962), Dusanic and Lewert (1963), and Gilbertson et al. (1967) provide information on some of the constituents of hemolymph and tissues from Biomphalaria glabrata. The shedding of the ciliary plates of miracidia kept in solution containing snail extracts, saline, and agar was reported by Targett and Robinson (1964). Chernin (1964) maintained larval Schistosoma mansoni in snail tissues in vitro. Muftic (1969) claimed to have achieved development in vitro of S. mansoni cercariae from miracidia, but the lack of information in his paper casts doubt on the validity of his observations. In studies reported below we have attempted to define some of the requirements for the shedding of cilia and axenic and monoxenic differentiation in vitro of schistosome miracidia to stages resembling young sporocysts.

Objectives: We report a late diagnosis of a rare case of extramedullary maxillary sinus plasmacytoma. It is important to investigate for nasty pathology if the patient has a long history of nasal bleeding even if he had a recent history of nasal surgery. Case report: Although extramedullary maxillary sinus plasmacytoma is a rare presentation, the head and neck region is the most affected area and maxillary sinus is the most of head & neck to be involved. Its clinical and histological diagnosis is difficult. This is a reported case with its clinical, radiological and histological features. Conclusion: If a patient presented with long history of recurrent nasal bleeding, nasty pathology should be excluded even if he had recent history of nasal surgery.

The teacher training reform implemented in France from 1990 onwards was a major event which had and still has repercussions throughout the French education system. A critical analysis of the events is presented. In particular, it shows the difficulty of introducing change in the context of the French education system and exemplifies how political decisions made along clearly defined lines can be partly diluted in the implementation stage by the various stakeholders of the system. At the same time, it makes apparent that the creation of the new teacher training institutes, which was an integral part of the reform, has brought about the conditions for change in the medium or long term. Aspects of this discussion will also serve to illustrate questions about teacher training which are of interest in other countries.


Effective construction research requires proper application of social science research methods. The use of proper statistical analysis is crucial and there is a need to perform multivariate analysis in order to eliminate spurious relationships. Structural equation modelling (SEM) is increasingly being applied for ; with ISO 9001 certifications, this paper proposes to classify the benefits gained from ISO 9001 registrations into three categories, namely, company competitiveness, customer satisfaction and business performance. It also reports on the statistical procedures taken and the findings from SEM the causal effects of ISO 9001 registrations efforts. Key elements in the application practice and reporting of SEM are presented. The impact of construction research work can only have a reasonable result if there is consistency and repeatability for the further advancement of construction management research.


Summary Minimal-growth storage may be a simple method to preserve germ plasm while tree varieties undergo clonal selection, but there has previously been little evidence to demonstrate that minimal-growth storage delays maturation. This study assessed the maturation of 10 Corymbia torelliana × C. citriodora clones whose shoots had been stored for 12 months using three different methods: (1) as ex-vitro stock plants in the nursery; (2) in-vitro at 25°C; and (3) in-vitro under minimal-growth conditions at 14°C. Minimal-growth storage increased the subsequent frequency of adventitious rooting in cuttings of 6 of the 10 clones, providing increases in rooted cutting production of between 53% and 163% over ex-vitro nursery storage. Minimal-growth storage also increased adventitious root number in two clones and root mass in four clones. C. torelliana × C. citriodora clones underwent maturation during ex vitro stock plant archiving in the nursery, but in-vitro storage under minimal-growth conditions was highly effective in delaying clonal maturation.


The Rashtriya Swayamsevak Sangh has always sought to exercise an ironclad control over its political offspring, the Bharatiya Janata Party. The machinations of the former have directed the fortunes of the latter, including determining who the party president should be. Over the last two decades, however, there have been many changes in the relationship between the two. Most recently, while the current Sangh chief, Mohan Bhagwat favoured "regional" leadership of the party over Delhi-centric leaders, his choice, Nitin Gadkari, had to step aside and make way for Rajnath Singh. The run-up to the 2014 general elections will tell if the BJP will assert its identity or if the Sangh will try to regain complete control.

The southern African species of Syngenes Kolbe, 1897, are revised and compared with their Afrotropical congeners. Three species occur in the region: S. longicornis (Rambur, 1842) and two new species, S. medialis and S. scholtzi, described and illustrated below. A key to the Afrotropical taxa is provided. The larva of S. longicornis is illustrated. The genus is widespread in the Afrotropical Region and extends to the Middle East and Oriental Region. Syngenes species are typically broad-winged antlions, with irregular bifurcate and biaereolate cells between the costa and subcostal veins, which distinguish them from other members of the tribe Acanthaclisini.


The cluster streaming media server has gradually become the mainstream of the high-end streaming media server.The scientific simulation system is needed in the research work about the optimization of the resources allocation and the related algorithm of the cluster streaming media.Based on the architecture of the cluster streaming media server,this paper designs and implements a cluster streaming media server simulation system based on our cluster streaming media server test bed.At last,some useful conclusions,which discover the performance bottleneck of the cluster and optimized configuration of the resources,have been given based on the simulation data.


One of the advantages for Discrete Multitone(DMT) modulation systems compared to single carrier systems is that the power and bits may be allocated to each subchannel in some way for optimal performance. Some algorithms proposed before have high complexity and use flat power distribution which is not the optimal distribution. Based on the detail analysis of Water-Pouring theorem, a new practical algorithm is presented which match approximately matches the Water-Pouring distribution and can also the discrete bit loading problem. The simulation results show this algorithm has better performance and lower complexity.


The catalytic properties of copper(II) oxide powders were studied in the CO oxidation reaction by using plug‐flow and flow‐circulation reactors. Data obtained from different catalytic experiments were in good agreement with each other. The specific catalytic rate [molecules cm−2 s−1] increased by a factor of approximately four if the surface area of the CuO powder was reduced from 90 to 8 m2 g−1. A further decrease in the CuO surface area to 1 m2 g−1 resulted in the decrease of the specific CO oxidation rate by more than 20‐fold. These results indicate that CO oxidation is sensitive to the structure of the copper(II) oxide catalyst. The structural sensitivity of CuO powders was discussed in terms of its defect structure and particle morphology.


Abstract The chemical–physical environment around iron based FTS catalysts under working conditions is used to estimate the influences of carbon containing gases on the surface structures and stability of ε-Fe2C, χ-Fe5C2, θ-Fe3C and Fe4C from combined density functional theory and atomistic–thermodynamic studies. Higher carbon content gas has higher carburization ability; while higher temperature and lower pressure as well as higher H2/CO ratio can suppress carburization ability. Under wide ranging gas environment, ε-Fe2C, χ-Fe5C2 and θ-Fe3C have different morphologies, and the most stable non-stoichiometric termination changes from carbon-poor to carbon-rich (varying surface Fe/C ratio) upon the increase in ΔμC. The most stable surfaces of these carbides have similar surface bonding pattern, and their surface properties are related to some common phenomena of iron based catalysts. For these facets, χ-Fe5C2-(100)-2.25 is most favored for CO adsorption and CH4 formation, followed by θ-Fe3C-(010)-2.33, ε-Fe2C-(121)-2.00 and Fe4C-(100)-3.00, in line with surface work function and the charge of the surface carbon atoms.


By using "space instead of time" approach,this paper studied the niche dynamics of plant populations and the changes of plant functional types along a successional series on zokor mounds.Twenty main plant species were chosen to analyze their niche breadth and overlap by using the Shannon and Pianka indices.The results showed that larger niche breadth was often accompanied with larger niche overlap,but some plant species with smaller niche breadth also had larger niche overlap.The niche overlap among plant species was generally large.With the succession,the annual or biennial forbs first decreased rapidly and then slowly increased but overall decreased,the perennial forbs decreased after an initial increase,while the perennial grasses increased linearly,reflecting that perennial grasses finally dominated the climax communities.The grassland quality index was used to analyze the vegetation cover on the mounds,and the results indicated that with the succession,the grassland quality index increased significantly.


We read with great interest the recent article by Radzikowski et al on immunogenicity of the hepatitis A virus (HAV) vaccine in pediatric patients with inflammatory bowel disease (IBD). As outlined by the authors, there are few studies investigating the immune response to vaccinations in children with IBD. The authors specifically looked at immunogenicity of the HAV vaccine in pediatric IBD patients when compared to healthy controls. They vaccinated eligible patients with Havrix (GlakoSmithKline, Rixensart, Belgium), on a two-dose schedule of 0 and 6–12 months. They measured total anti-HAV antibodies prevaccination, at 4 and 12 weeks after the first dose, and 4 and 12 weeks after the second dose. Among the 66 IBD patients and 68 control patients, they found no significant difference in seroconversion after the second dose of the vaccine between the two groups (97% vs. 100%, P 1⁄4 0.2407). 6-Mercaptopurine (6-MP) or azathioprine (AZA) treatment with and without steroids did not affect seroconversion rates, but monotherapy with steroids reduced the rate of seroconversion at 4 weeks after the second dose. Their results were consistent with existing reports of HAV seroconversion in healthy patients and in patients with chronic liver disease. Of note, none of the patients in the study were on a biologic medication, such as infliximab. Herein we aimed to investigate the immunogenicity of the HAV vaccine in pediatric IBD patients receiving infliximab. We screened 100 patients for total anti-HAV antibodies and found that 14 patients (14%) had protective antibodies. We were able to enroll 12 patients who did not have anti-HAV antibodies to receive the full series of the vaccine. We used Havrix on a 0 and 6–12 months schedule, at a dose of 720 enzyme-linked immunosorbent assay (ELISA) units (ELU) per 0.5 mL for patients less than 19 years of age and 1440 ELU per 1 mL for patients 19 years of age and older, per the manufacturer's recommendations. We checked the total anti-HAV prevaccination and 4 weeks after the second dose of the vaccine. The mean age at time of vaccination was 18.3 years (range 13–23 years) with a mean age at IBD diagnosis of 12.8 years. There were eight males and four females in the study. Overall, we found a seroconversion rate of 92% (11/12 patients) when the total anti-HAV was rechecked 4 weeks after the second dose. All of the patients were receiving infliximab at the time of vaccination and none of the patients were on concurrent steroids or 6-MP/AZA. Of note, two of the patients were on concurrent methotrexate, both of whom were responders to the HAV vaccine. In summary, we found a high rate of seroconversion to HAV vaccination in pediatric patients treated with infliximab for IBD. Taken together with the results of the study by Radzikowski et al, there is convincing evidence that pediatric IBD patients on a wide variety of medications for control of their disease are likely able to respond adequately to the HAV vaccine.

Background and Objectives: Studies have shown that polycystic ovary (PCO) may be induced by morphine and CA1 may be damaged by PCO-related oxidative stress but can be protected by a potent GABAB receptor agonist. Therefore, this study aimed to investigate the protective effect of baclofen against oxidative stress in the dorsal hippocampus (DH) of morphine-treated rats with ovarian cysts.
Materials and Methods:  In total, 66 female Wistar rats were selected and randomly divided into control and experimental groups. The control group received saline (1 ml/kg, intraperitoneally [i.p.], once a day). Experimental groups were treated with morphine (5 mg/kg, i.p.), baclofen alone (10-30 mg/kg, i.p.), and baclofen (10, 20, 30 mg/kg, i.p.) before morphine (5 mg/kg, i.p.), once daily. One group received morphine (0.4 µg/rat) once in the ventromedial hypothalamus, and the last ovariectomized group was administered morphine (5 mg/kg, i.p.) after recovery. Then blood and hippocampus samples were prepared. Moreover, the levels of oxidative stress factors (GPX, MDA, SOD, and CAT), and the intensity of estrogen and glucocorticoid receptors in DH were evaluated. Ovaries and the uterus were also examined biometrically.
Results: In the morphine-treated groups, regardless of the injection method, the development of follicles was rare, compared to the control group, instead, thick-walled follicular cysts were abundant. However, in the groups that received baclofen alone or baclofen together with morphine, the number of cysts decreased and the number of mature follicles increased significantly. Oxidative agents showed high levels in the DH of the morphine-treated group, which correlated with low estrogen receptors in DH. However, baclofen pretreatment improved these conditions. Besides, glucocorticoid receptors in DH did not show significant differences in different groups, and necrosis in the CA1 area was not observed either in the morphine-receiving group or in the other groups. The uterus did not show significant changes in any group.
Conclusion: Prophylactic use of baclofen can protect against morphine side effects.


High quality, epitaxial undoped, Zn- and Se-doped GaAs films have been grown by metal organic chemical vapor deposition (MOCVD) on flexible metal substrates using buffered Ge epitaxial templates. The GaAs films exhibit strong (400) orientation, sharp in-plane texture, strong photoluminescence and a defect density of ~107 cm-2. Furthermore, the GaAs films exhibit hole and electron mobilities as high as 106 and 872 cm2/V-s respectively. Also, roll-to-roll MOCVD growth of epitaxial GaAs films has been demonstrated for the first time on flexible metal substrates. These high mobility single-crystalline-like GaAs thin films on inexpensive flexible metal substrates are being developed for high efficiency, low cost thin film III-V solar photovoltaics (PV).


Wireless Local area networks are used at a large scale in present world. A large number of devices communicate in a WLAN but the channels used for this purpose are limited which gives birth to congestion in the network. The main challenge in WLANs is the allocation of resources. Two types of TCP flows i.e., uplink and downlink exist WLAN, but with their existence at the same time the network service is somewhat biased towards uplink due which the downlink transmission flow suffers. In this research paper, we propose an optimization scheme based on the working of Artificial Bee Colony Optimization algorithm for dynamic allocation of multi-queue buffer for TCP flow in WLANs. The simulations are performed in MATLAB and the results are achieved in terms of throughput, drop packet and other parameters to prove the effectiveness the proposed technique.


Technical and industrial competences are increasingly dispersed across the globe, urging young high-technology firms in Europe to increase distances in their knowledge relations. However, establishment and maintenance of such relationships tend to be hampered by many barriers following from short in capabilities, particularly various missing skills in the management team. In this paper, we examine the role of capability factors and particular skills among a specific category of firms, university spin-offs, in building knowledge networks abroad, specially, the spatial reach involved. Such a study is not new for (innovative) SMEs, but it is new for university spin-off firms. We use two samples of university spin-off firms (each about 100 cases) in various European countries in order to identify the importance of capabilities and certain skills in internationalization of knowledge collaboration, and to this purpose we apply various regression models. The sampled firms are of different age and find themselves in different stages of born-global development. We observe that 60 to 70 per cent of the firms employ knowledge relationships abroad, almost 35 per cent of them outside of Europe. The main underlying capability factors are a high education level (PhD), participation in market/business-related training, and a larger firm size. Another factor is a relatively low level of innovation, indicating a support structure from practical application and customer relations in an established market position of the firm abroad. Examples of such support structure are found in civil engineering works and consultancy concerning transportation infrastructure, land use/protection and the oil and gas industry. Furthermore, one set of missing skills in the management team stands out in limiting larger distances in knowledge collaboration, and these are internationalization skills, for example, skills in presentation of the firm and negotiation of important agreements with a partner abroad, dealing with uncertainty in certification issues and patent protection, and skills in branding the product abroad. Most missing skills are of the conceptual and relational type. Due to different stages in born-global development, the differentiation in missing skills is remarkably large, indicating that training to improve skills requires a multi-faceted and customized approach, without a one-size-fits-all solution. The paper concludes with a summary and some ideas for improving training.

ABSTRACT There have been many attempts over the last five decades to measure students' attitudes towards school science. Many of these studies investigated attitudes towards limited aspects of science and utilized large numbers of items to draw snapshot summaries of the educational landscape. An understanding of attitudes towards science, and how these change over time, is of particular importance to educators in Australia and farther afield, who are forming a response to the continued declines in enrolments seen in post-compulsory science courses. We identify a gap among the available instruments for a tool that can measure multiple facets of attitudes using a minimal number of items, while being suited for use in pre-/post-test and longitudinal studies. In this article we describe the definition, validation and statistical refinement of a digital survey tool using single-item web-based visual analogue scales to measure five key perceptions of school science that lead to the formation of a Science Attitude Profile. We suggest that a particular strength of the resulting data analyses is the ability to provide a comparative 'does it work?' critique of various interventions implemented by educators and inform local and national educational policy.

Solid state nuclear track detectors (SSNTDs) have been recognised by IAEA as a standard method for estimation of radon, thoron and their daughter products in the environment. The detectors that are commonly used in environmental monitoring are generally made from cellulose nitrate (LR-115) and polycarbonates (CR-39). In view of the non-availability of these detectors in India, need was felt to develop them indigenously. Accordingly, an attempt has been made to develop cellulose nitrate films for their use in SSNTD. Cellulose nitrate with a particular nitrogen content was used for preparing these films by a cast method. This films were annealed, evaluated and then compared with imported films. The background track density and alpha track density after exposure to 150 nCi of /sup 241/Am source at 2.5 cm distance were found to be comparable with those of imported films.


A novel polarimetric synthetic aperture radar (PolSAR) image classification method based on Deep Belief Networks (DBNs) is proposed in this paper. First, the coherency matrix data are converted to a 9-dimentional data. Second, many patches are randomly selected from each dimension in the 9-dimentional data, and many filters can be obtained from a Restricted Boltzmann Machine (RBM) trained by using these patches. Thus we can get the features for each pixel from each dimension in the 9-dimentional space. Finally, the learned features and the elements of coherent matrix are combined to train a 3-layers DBNs for PolSAR image classification. Experimental results show that the proposed method is efficient and effective for PolSAR image classification.


Abstract: The existing topologies, Multilevelinverters acts as a promising solution for medium voltage, high power applications due to their modularity and reduced voltage stress across the power switches. They are becoming popular due to reduced voltage stress of the power switches and low THD. Among the different multilevel configurations, H bridge multi-level inverter (HBMLI) is found to beattractive for grid connected PV applications. H Bridge Multilevel Inverters (HB-MLI) are being considered as the best choice for grid connected Photovoltaic (PV) systems since they require several sources on the DC side. By means of high-quality output with less harmonic distortion is obtained compared to a two-level inverter. Different levels of output viz. three level is examined and conclusions are drawn mainly based on the number of switches andTotal Harmonic Distortion (THD). The main advantages of the multilevel inverter are that the regulation of the DC buses is simple. More number of levels results in reduced THD and nearly sinusoidal output. Simulation is performed using Matlab/Simulink.


Abstract— The initial deposition pattern in the nasal passages and subsequent clearance of an insulin formulation labelled with 99mTc‐human serum albumin have been determined in 12 healthy male volunteers. Four different administration modes from a novel aqueous spray device were compared, involving delivered volumes of 80–160 μL, and with either gentle or vigorous inhalation while firing the device. The entire dose was deposited in the nasal cavity, and no significant radioactivity was deposited in the lungs. A mean 25–33% of the radiolabel remained in the nose after 4h. A significantly smaller area of the nasal mucosa was covered by the smallest (80 μL) bolus, but subsequent clearance rates did not vary significantly with mode of administration. Blood glucose levels fell after administration of the insulin formulation, but no serious episodes of hypoglycaemia occurred.

In this research, an attempt has been made to evaluate the structural response of multi‐storey composite modular buildings when subjected to lateral wind loads. Finite element (FE) models were developed in Abaqus for a general 10 storey composite modular building, with and without the consideration of lateral load resisting mechanisms of composite shear walls. Concrete filled steel tubular (CFST) columns and composite shear walls were proposed in place of conventional elements to improve the structural resistance, modularity, and construction timeframe. It was observed that under the effect of wind loads, the forces between the modules are transferred primarily by horizontal axial forces. When the effect of sudden module removal is considered along with the wind, the vertical shear forces in the horizontal inter‐module connection increase and the connection becomes critical in shear. Even though the probability of occurrence of critical wind loads and a sudden module loss is rare, it was concluded that the wind forces do not influence the overall stability of the structure in the event of progressive collapse by sudden module removal if an effective lateral load resisting mechanism has been designed.


Regulatory toxicology helps define the balance between health risk and societal benefit of chemicals by applying a science-based approach, thus representing a potential career opportunity for scientists involved in biomedical research.


The high intensity accelerators are one of the world-wide leading edge research in the beam dynamics studies. The upgrades of the existing accelerator LINAC4, FERMILAB, FAIR and the new applications on the neutron technologies such as ESS, IFMIF, MUNES, both for science research, medical treatment and material testing require an increase knowledge in the high intensity beams treatment. One of the most difficult part to be treated and which represent the first obstacle in increasing the beam intensity in the accelerators, is the injector part: the large number of charge particles at low energy forms a strongly interacting system, subjected to the Coulombian interaction. The situation further complicates due to the presence of different species which produces a plasma-like behavior of the beam. On the behalf of the INFN-LNL team, I participated to the commissioning of the high intensity injector (source and low energy transfer line) of the IFMIF/EVEDA project. Via experiments and simulation model developments I contributed to the study of the beam behavior in this specific framework. In particular I upgrade the emittance measurement routine in order to manage correctly the artifacts; I develop and benchmark with measurements self-consistent simulation models of the LEBT and extraction transfer line, which includes the secondary
electron from residual gas and from metal due to collisions; I design a modification of medium and high energy line in order to test the CW steady state of the longest radio frequency quadrupole in the world, an in-kind contribution of INFN. All the development routines and experience will give important contributions for the next high intensity facilities. The first
chapter presents the motivation of the IFMIF project and the main characteristics required by the accelerator. The main challenges of such accelerator are also listed. The second chapter introduces the main concepts of the beam dynamics of space-charge which will be used in
the thesis. The third chapter presents the IFMIF/EVEDA project, with a description of the main elements; particular focus is made onto the source, the low energy beam transfer line and on the radio frequency quadrupole. Scaling law derivation for the extracted beam with contaminants is shown. The commissioning phases are introduced, each with its specific
challenges. The fourth chapter presents the modification of the emittance analysis routine which can manage the ghost infested signal of the IFMIF/EVEDA emittancemeter. The fifth and the sixth chapters contains the simulation models developed to estimate the space-charge
beam behavior under neutralization regime: the model with constant neutralization and the one with the full secondary plasma evolution are presented and benchmarked with the measurements. In the fifth chapter the measurements refers to 60−55 mA proton beam at 50 keV, while for the sixth chapter the beam considered is composed of 140−135 mA deuteron beam at 100 keV. In these chapters, the variation of the radio frequency quadrupole beam input characteristics with respect to the electromagnetic plasma confinement of the low energy transfer line is studied. The original contribution in these simulations is given by the emitted secondary electron from metal, which as some effects on the space charge compensation process, on the emittance value. Deep study of the multispecies distributions and behavior was performed. The four chapter defines, for the experimental proton point considered, the
solenoid variations where searching the maximum radio frequency quadrupole transmission. The output beam behavior of this one is studied in commissioning perspective. In thesixth chapter, after testing the radio frequency quadrupole transmission with the secondary plasma model (also said dynamic neutralization model) with a realistic beam distribution, the
simulations of the extraction system are presented. The benchmark with the measurements are also performed. The seventh chapter presents the design of the modification of the medium and high energy transfer sections of the accelerator in order to allow the test of the CW of the radio frequency quadrupole, bypassing the superconductive cavities. Extensive
simulations of the system robustness to the errors are explored. The last chapter reports the conclusions.


Approved: (Major Pfessor) The umbellulone was isolated from the myrtle oil by the sulfite method, which was found to be the most inexpensive and convenient method of obtaining the pure ketone. The umbellulone wa hydrogenated in the vapor phase over a nickel catalyst, ass1ng it through an electric tube furnace, in an attempt to compare the course of the reduction with that obtained by previous investigators operating upon a liquid nhase. The products of each hydrogenat.ori at different temoeratures from 2500 to 375°C. were analyzed for ketone, alcohol, and phenol contents, and for Iodine value to determine unsaturation. Their physical constants, including specific gravity, optical rotation, and refractive index were also determined. Theresults so obtained were compared with those of the original ketoneused and the following conclusions were shown:1. At temperatures below 300°C. partially saturated hydrogenated compounds were obtained. 2. At higher temperatures rearrangement took place converting umbellulone into phenols, specifically thymol. 3. The relative increase in alcohol content with a decrease in ketone content is probably due to a conversion


Palas Merino breed was homologated in 1960. It developed since 1935 as a population almost isolated in the reproductive point of view, the isolation being total during 1940-1950 and 1970-2003. During its evolution, there were 8 migrations. After each migration, the genetic similitude of the breed with this raised the similitude with previous immigrations being diminished. During 1930-1940 the genetic similitude of the breed with Ramboiullet Merino was of 42.3-40.0%, this being decreased at 2.26% in 1970, disappearing in the breed evolution after this year. The genetic similitude with German Semiprecoce Merino progressively increases after 1930 (14.9%) reaching the value of 47.72% in 1950, and then decreases to the value of 12.78% in 1970. Diminishing the genetic similitude with this breed continued also 1970 reaching the zero value after 1980. Beginning with 1953 Palas Merino suffers the influence of Merino of Stavropol and Caucasian Merino breeds, imported from the former USSR. After1970 Palas Merino has also suffered the influence of Australian Merino breed. It can be shown that the present Palas Merino have cca. 92% of the genes of the population that was homologated in 1960 and 5% from the genes of Australian Merino breed. During the whole studied period (1930-2003) the medium interval between generation was of 4.11 years, being bigger on mother-son and mother-daughter filiations; the selection was made on own performance and mother's performance (the sheep retained for reproduction consisted of older sheep "good at wool and milk"). The total inbreeding of Palas Merino breed increased from the value of 2.75% in 1940 to 7.24% in 1970, then decreasing to the value of 2.03% in 2003. These data show that during breed's evolution the practice of inbreeding was systematically avoided.


The purpose of this paper is to examine the relation between gold return and returns from USD/INR, crude oil and FMCG Index returns and whether its relation changes in times of gold market returns for an emerging market. Since 2000 the gold price has risen drastically, making gold an interesting add-on to a portfolio. Given that the gold market and the crude oil market are the main representatives of the large commodity markets, it is of crucial practical significance to analyse their co integration relationship and causality, and investigate their respective contribution, from the perspective of price discovery, to the common price trend so as to interpret the dynamics of the whole large commodity market and forecast the fluctuation of crude oil and gold prices


In this paper PECVD SiO2/Si3N4 double-layer electrets were investigated for their compatibility with micromachining technology, such as conventional lithography and etching techniques. After the experiments, we find that no matter under what condition, either high temperature or high humid condition, could H3PO4 improve the charge stability of SiO2/Si3N4 double-layer electrets a little. RIE and oxygen plasma stripping reduce the charge stability significantly. Acetone stripping does not influence the charge stability in high temperature and high humidity. The other techniques, such as BHF, fuming nitric acid stripping, corrosive of Al and Au etc., decrease the charge stability a little.


The automatic stop-and-go task of intelligent vehicles can make the adaptive cruise control system achieve a full-speed range. However, the conventional design methods mostly focus on functional safety, without considering drivers' behaviors, thereby leading to a poor driving experience. To improve the situation, a humanized learning control model is used instead of mechanical switching logic. Therefore, first, the common characteristics of human drivers with different driving styles are found by analyzing real drivers' experiments. Then, the vehicle automatic starting function is designed based on iterative learning control with the fast Fourier transform for acceleration fitting. Next, the vehicle automatic braking function is designed based on dynamic time to collision. Finally, the simulation of the stop-and-go scenario is shown in CARSIM, and the real vehicle test is performed under the urban overpass driving condition. Results show that the proposed model can improve the humanization in the vehicle stop-and-go task.


The High and Thermal Magnetic Processing/Electro-magnetic Acoustic Transducer (HTMP/EMAT) technology has been shown to be an enabling disruptive materials processing technology, that can achieve significant improvements in microstructure and consequently material performance beyond that achievable through conventional processing, and will lead to the next generation of advanced performance structural and functional materials. HTMP exposure increased the reaction kinetics enabling refinement of microstructural features such as finer martensite lath size, and finer, more copious, homogeneous dispersions of strengthening carbides leading to combined strength and toughness improvements in bainitic steels. When induction heating is applied in a high magnetic field environment, the induction heating coil is configured so that high intensity acoustic/ultrasonic treatment occurs naturally. The configuration results in a highly effective electromagnetic acoustical transducer (EMAT). HTMP combined with applying high-field EMAT, produce a non-contact ultrasonic treatment that can be used to process metal alloys in either the liquid state resulting in significant microstructural changes over conventional processing. Proof-of-principle experiments on cast irons resulted in homogeneous microstructures in small castings along with improved casting surface appearance. The experiment showed that by exposing liquid metal to the non-contact acoustic/ultrasonic processing technology developed using HMFP/EMAT wrought-like microstructures were developed in cast components. This Energymore » Intensive Processes (EIP) project sponsored by the DOE EERE Advanced Manufacturing Office (AMO) demonstrated the following: (1) The reduction of retained austenite in high carbon/high alloy steels with an ambient temperature HTMP process, replacing either a cryogenic or double tempering thermal process normally employed to accomplish retained austenite transformation. HTMP can be described as a 'heat-free', heat treating technology. Lower residual stresses in HTMP treated materials are anticipated since no thermal strains are involved in inducing the transformation of retained austenite to martensite in high alloy steel. (2) The simultaneous increase of 12% in yield strength and 22% in impact energy in a bainitic alloy using HTMP processing. This is a major breakthrough in materials processing for the next generation of structural materials since conventionally processed materials show a reduction in impact toughness with an increase in yield strength. HTMP is a new paradigm to beneficially increase both yield strength and impact energy absorption simultaneously. (3) HTMP processing refined both the martensite lath population and the carbide dispersion in a bainitic steel alloy during Gausstempering. The refinement was believed to be responsible for the simultaneous increase in strength and toughness. Hence, HTMP significantly impacts nucleation and growth phenomenon. (4) HTMP processing developed comparable ultimate tensile strength and twice the impact energy in a lower cost, lower alloy content ({approx}8% alloy content) steel, compared to highly alloyed, (31% alloy elements involving Ni, Co, and Mo) 250-grade margining steel. Future low-cost HTMP alloys appear viable that will exceed the structural performance of highly alloyed materials that are conventionally processed. This economic benefit will enable U.S. industry to reduce cost (better more competitive worldwide) while maintaining or exceeding current performance. (5) EMAT processed cast iron exhibits significantly higher hardness (by 51% for a 9T condition) than a no-field processed sample. (6) EMAT produced microstructures in cast iron resulted in an unique graphite nodule morphology, a modified pearlite content, and unique carbide types, that formed during solidification and cooling. (7) EMAT processed nanoparticle dispersions in Mg resulted in a very fine, unagglomerated distribution of the nanoparticles in the magnesium matrix. This provides a breakthrough technology to make the next generation of nanocomposite reinforced metal matrix composites which can be tailored to exhibit higher strength and ductility combinations not only at ambient temperature but at elevated temperatures where enhanced creep resistance is observed. This technology can be extended to non-metallic systems as long as a conductive containment vessel is utilized that will convey the EMAT signal into the material of interest during processing. (8) Facilitation of HTMP/EMAT technology commercialization, throughout the course of the project. Two technology limitations were overcome that led to the first generation commercial prototype HTMP/EMAT system which was initially installed at ORNL. (9) During this project, a production-scale equipment design to enable commercialization of HMFP technology was conceptualized, designed, fabricated, and installed at ORNL as a commercial-scale prototype system.« less


Seismic noise methods are nowadays widely used in geophysics being easy and non-invasive techniques to characterise the subsoil. In the present study I use F-K and H/V methods to process data collected on the Cerdanya Basin during 2012 by ICGC. The main object iv has been to determine the thickness of the basi n sedimentary materials in two different locations: G er, above the mountain, and an aerodrome, down the valley. H/V method uses single geophones to record triaxial sei smic noise vibrations. The data processing is able to find the resonant frequency of the soil, which is a good ind icator of the sedimentary material thickness but do es not provide a numerical value. On the other hand, F-K method go es further and uses arrays of registering stations t acquire data. The processing and inversion of this seismic no se gives the Rayleigh waves propagation velocity for each subsoil layer, giving way to a good characterisatio n of the material that conforms them. This characte risation allows us to estimate the rocky basement depth, which fina lly becomes in 360 meters for the aerodrome and 100 meters for Ger. The final processing method performed has been to combine the results from the two previous metho ds to achieve a second thickness numerical measure, which approaches to the previous results obtained.

Ion beams have been used to nucleate embedded nanocrystals into different material matrix, such as using of N implantation into InP and N co-implantation into Si[1]. By other hand there has been a lot of interest in indium nitride materials due to their potential applications in optoelectronic devices. Indium nitride presents high mobility and high saturation velocity due to its low effective mass, which makes it applicable in high speed and high frequency electronic devices. It is shown in the literature that it is possible to operate indium nitride-based light emitting diodes at spectral wavelengths ranging from the near-infrared to the ultraviolet region of the electromagnetic spectrum. Inspired in the importance of InN and the possibility to form nanocrystals into other material by ion implantation. In this work we present a shallow (low energy)/(high dose) ion implantation of In+ into pGaN to study the possibility to form nanocrystal nucleation and its effect in luminescence emision. The characterization was performed by SIMS, HXRD, Raman and Photoluminescence. SIMS was used to study implantation distribution and its redistribution by thermal treatment, since an out-diffusion was observed as thermal annealing increase causing a reduction of its atomic concentration form 2x10 to 5x10 cm for as implanted sample to annealed at 900°C respectively. Structural characterization by HRXD and Raman revels crystal recovery for high temperature as 900°C. From PL spectroscopy red shift was found for as implanted sample and the shift was decreased as annealing temperature increase. Furthermore an additional transition was observed around to 1.5 eV attributed to InN nanocrystals emission. In conclusion the ion implantation at low energies and high dose of In+ into GaN was studied by analytical techniques where interesting emission was observed attributed to quantum confinement due InN nanocrystal nucleation into GaN.


An approach combining the use of the hot-wire method with the solution of heat conduction inverse problems is here proposed for the thermal characterization of new polymeric materials. Due to the low thermal conductivity of the material, the cross technique is used instead of the parallel technique. The inverse heat conduction problem has been solved as a finite dimensional optimization problem with the LevenbergMarquardt method. Results are presented for phenolic foams with lignin thermal conductivity and diffusivity estimation from a real set of experimental data. INTRODUCTION A considerable amount of effort has been devoted for the fulfillment of the ever-growing demand for new materials with relevant applications in engineering and medicine. The recent trend has been the development of specific materials for new applications, with the latter coming first. It becomes mandatory, then, the use of the adequate techniques to characterize the new materials developed, through the determination of their properties. Besides that, the accurate modeling (physical, mathematical and computational) of systems and components of engineering interest, relies heavily on the use of the proper values for the material properties. For applications involving heat transfer by conduction, the thermal conductivity and diffusivity are the most relevant properties to be considered. Carvalho et al. (1996) measured the thermal conductivity of polymers with the hot-wire method. Shai et al. (1993) measured the thermal diffusivity of solids, and Trevisan et al. (1993) measured the same property for saturated porous media. Experimentalists use a lot of engineering skills trying to control several degrees of freedom during the development and operation of experimental apparatus and techniques to determine the required material properties. Combining the experimental activities with the solution of heat conduction inverse problems, a larger number of degrees of freedom may be taken into account, even allowing the simultaneous estimation of new unknowns brought into the problem by the more accurate mathematical modeling. Using the solution of inverse conduction problems Mikhalev and Reznik (1989) estimated the temperature dependence of the thermal conductivity of orthotropic materials, and Cheng and Zang (1994) estimated the spatially dependent thermal conductivity in optically opaque solids. Artyukhin (1976, 1982, 1982a), Tervola (1989) and Artyukhin et al. (1984, 1993) have used the expansion of the temperature dependence of unknown thermal conductivity, or thermal diffusivity, in known functions such as polynomials or splines, reducing the inverse problem of function estimation to that of determining the expansion coefficients. One of the most relevant applications of the inverse analysis is related to the design of experimental apparatus and techniques as well as the optimal use of existing equipment or experimental data already acquired (Artyukhin and Okhapkin, 1984; Emery et al., 1993). The approach involving the solution of inverse problems is well fit to perform those tasks. In some of the techniques developed, sensitivity coefficients have to be calculated during the procedure used for the solution of the inverse problem, and the confidence bounds for the estimated values are related to these sensitivity coefficients. Going one step further, the criteria used for the design of optimal experiments may be related to the minimization of the confidence region (Taktak et al., 1993). Therefore, through this approach a significant gain in experimental simplicity and productivity can be achieved (Goryachev and Yudin, 1983). In this work we present the first results of our efforts towards the physical, mathematical and computational modeling of the hot-wire method for the estimation of new polymeric


Wavelength Modulation Spectroscopy (WMS) was utilized to study the exhaust flow of a scramjet combustor with a combined operation mode in this work. 8 optical probes for WMS, 5 vertically with a spacing of 5cm and 3 horizontally with a spacing of 3cm, were mounted on the jet nozzle of the combustor, which was operated in 3 combustion stages, H2 combustion at first, kerosene combustion in oxygen-rich condition and fuel-rich condition, sequentially. The WMS system recorded the complete process of combustion, then simultaneously inferred the temperature, H2O concentration and pressure from each sensor. Measured results showed that the parameters of interest in all the 3 stages, during 5.4s combustion period, had relatively stable values. However, when the stage transited to the next, the combustion parameters leaped rapidly in 20ms. The WMS system had fast enough response speed and successfully caught the leaping. The 2D distributions of temperature and H2O concentration were also reconstructed, which illustrated that the combustion flow was not uniform in each stage.


The Internet of Things (IoT) malware keep evolving and utilize multiple vulnerabilities to infect IoT devices. Besides malware, human attackers also utilize various tools to access and collect variable information on the device. For instances, web UI of IP Cameras and routers are constantly searched and accessed if vulnerable. In order to observe and analyze such a variety of attacks in depth, there is an increasing need for bare-metal IoT devices as a honeypot, since it is costly to emulate device-specific vulnerabilities and complex functionalities from dedicated services. However, operating bare-metal IoT honeypots has unique technical challenges mostly coming from their low configurability as an embedded system. A bare-metal honeypot needs proper access control while it is allowing attackers to access its inside to some degree, such as filter out bricking commands and changes of critical configuration. From this observation, we propose ThingGate, a gateway for flexible operation of bare-metal IoT honeypot. ThingGate employs a man-in-the-middle proxy to control and manage inbound and outbound traffic of the bare-metal IoT honeypot. Moreover, it adds the functionality of web tracking, which is not provided by the web UI of the original devices. We evaluate ThingGate with seven bare-metal IoT devices and show that it successfully blocks unwanted incoming attacks, masks wireless access point information of the devices, and tracks attackers on the device web UI while showing high observability of various attacks exploiting different vulnerabilities.


Renewable energy is a rapidly developing area of the modern economy. As many experts forecast, global electricity consumption will double by 2050, while the share of renewable sources in energy generation will be 50%. For most states, the main incentives for the development of renewable energy are the ability to eliminate the consumption of fossil fuels and reduce the level of emissions of pollutants, while ensuring sustainable development of the country. At the same time, Russia, which has significant reserves of natural resources, is in no hurry to switch to the use of energy from renewable sources since it is believed that the country's subsoil can provide it with cheap energy resources for many generations to come. Therefore, introduction of renewable energy sources that are unable to compete with traditional energy without a developed energy infrastructure and established production is impractical. In our study we try to evaluate the efficiency of the introduction of renewable energy sources in the Krasnoyarsk Territory of Russia using the example of the Chinese experience.


White spot syndrome virus (WSSV) is one of the most serious biological threats that caused considerable economic losses in shrimp farming industry worldwide. Although vaccination of shrimp using recombinant subunit protein, such as VP28, was significantly improved shrimp survival, the commercialization of shrimp vaccine has been largely delayed due to the problems such as unsatisfactory efficacy. In this study, the efficacy of monomeric and dimeric recombinant VP28 (rVP28) proteins were compared in WSSV challenged Penaeus monodon. First, the construct of recombinant plasmids harboring a single copy or double copies of VP28 were transformed and expressed in Escherichia coli (BL21). The 6x-histidine tagged rVP28 were purified using Ni-NTA column prior to western blot analysis. Injection challenge tests were conducted in triplicate with 8 shrimp per replicate for each group and 9 shrimp per replicate for 1×rVP28 group. To examine the protective efficacy of the rVP28, the naïve shrimp were co-injected with 25 μg of either monomeric or dimeric rVP28 in combination with WSSV (10 dilution of the stock virus). While the positive control showed 100% cumulative mortality at the 9 day post-injection, the mortality of shrimp co-injected with monomeric and dimeric rVP28 were 41% and 21% mortalities, respectively. This result suggested that the dimeric rVP28 could be one of the promising strategies to increase the protective efficacy of the shrimp viral vaccine.


The experiment of flotation separation is made on the Cu (Ⅱ) -bearing waste water in the flotation column, through the flotation carrier of CGA (colloidal gas aphrons), which is prepared with SDS (anion surfactant C12 H25 SO4Na), and by piping in usual flotation foams. With the investigation of the effects of the work pressure of the column circulation pump, the pH values and the SDS dosage on the Cu ( Ⅱ ) removal ratio, and collimating all the operation parameters, the orthogonal experiment of Cu (Ⅱ ) flotation separation is carried out by means of partial factorial method. The experimental results reveal that the Cu (Ⅱ) removal can attain a ratio of more than 99% when the combination of CGA with usual column flotation foams is a-dopted in the treatment of Cu (Ⅱ) -bearing waste water.


This paper outlines the rationale of how technology can be a component of constructivist learning environments to support student learning in EFL classrooms. Constructivism values interaction, communication, learning communities, and collaboration during the learning process, beyond skill and drill and rote memorization activities or individual cognitive activities. This paper particularly focuses on how technology can foster authentic learning, ownership of learning, situated learning, collaborative learning, and learning with multimedia. This paper investigates how computers can be used to add the values listed above to EFL learning from a constructivist perspective, and how key elements of constructivism are exemplified on the Internet, in Email activities, and discussion boards. This paper also highlights the significance of media literacy and provides suggestions to enhance media literacy in English classrooms. In the last section, an extended definition of literacy and language education is discussed along with technology as a value system. In accordance with this new definition, teachers' roles in the Electronic Era are also newly defined to best support student learning in technology-enriched EFL classrooms.


Two field experiments were carried out at Abu-Hammad District, Sharkia Governorate,Egypt, during two successive summer seasons of 2017 and 2018 to study the impact of three seedpriming methods (hydro-priming, hormonal priming with GA3 and osmo-priming with PEG-6000)and three yeast extract concentrations [control (without spraying), 20 ml/l and 40 ml/l] on yield andsome of its attributes of peanut cultivar "Giza 6". A split plot design with three replications was used.Combined analysis results revealed that the yeast extract concentrations failed to cause significanteffect on the studied traits except pod number/plant, fodder yield/fad., and seed oil content. The nonsignificanteffect was in favor of foliar spraying with 20 ml/l for branch number/plant, podweight/plant, seed number/pod, pod yield/fad., seed yield/fad., seed oil content and oil yield/fad. Seedpriming methods acted significantly on each of good seedling percentage, branch number/plant, podnumber/plant, pod weight/plant, 100-seed weight, pod, seed and oil yields/fad., Seed hormonalpriming gave high value for each of the abovementioned traits except branch number/plant. Seedhormonal priming with 20 ml/l yeast extract foliar spraying gave high value for each of podnumber/plant, pod weight/plant and seed oil content.


Blooming filamentous algae recurrently overgrow macroalgae and seagrass in many coastal ecosystems, leading to potential losses in the functions and services these habitats provide. The seasonal reoccurrence of algal blooms is partly caused by excessive input of nutrients into coastal ecosystems. At the same time, overfishing of top predators has led to increased densities of smaller predators that reduce herbivore abundance. Managers of coastal ecosystems are in urgent need of information on how overfishing may act synergistically with eutrophication to promote algal blooms. In the present study, we model the interaction between the opportunistic filamentous algae Ulva spp. and the effective mesograzer (small invertebrate herbivore) Gammarus locusta L. under different nutrient regimes and predation rates by intermediate-size fish (4 to 12 cm). The aim is to as- sess how productivity, herbivory and predation interact to regulate seasonal algal growth under a range of scenarios, including temporal matching or mismatching between trophic groups. The model is parameterised with nutrient and demographic data from a seagrass ecosystem on the west coast of Sweden. Model simulations show that both nutrient level and herbivore abundance regulate seasonal algal biomass in the seagrass meadow. Their relative importance is dynamic and sensitive to the arrival times of herbivores in relation to the start of algal development in spring. Thus, herbivore presence and timing are crucial factors for the control of algal biomass, particularly during times when resource levels are ambient to slightly elevated. Simulations also show that it is mainly the predation rate and timing of predators, rather than food limitation, that limit herbivore abundance. As predation rates by invertebrates and smaller fish can be linked to the presence of larger and commercially targeted fish, overfishing may have similar effects to eutrophication in the seagrass ecosystems.


Using the teleseismic waveform data recorded by the seismic station Bachu( hereafter referred to as station BCH) i n the Tarim Basin and the seismic station Taxkorgan(h ereafter referred to as station TAG) i n the west Kunlun Mountains for years,we applied the receiver function H-κ stacking method to study the crustal structure beneath stations BCH and TAG. The results showed that there are obvious differences in the crustal thickness beneath stations BCH and TAG,and the regional crustal thickness and terrain have a very good corresponding relationship. There are high crustal average V P/ V S values beneath the two stations. The crustal thickness is 44 km,and the crustal average wave velocity ratio is 1. 849 beneath station BCH. There is a sharp discontinuity in the middle of the crust beneath station BCH at a depth of 21 km. There is a low average P wave velocity and low V P/ V S from the surface to the discontinuity beneath station BCH.The depth of the discontinuity is consistent with the lower interface of the focal depth from accurate location in the Jiashi earthquake source area adjacent to station BCH; and may be the crustal brittle-ductile conversion boundary. The crustal thickness is 69 km,and the crustal average wave velocity ratio is 1. 847 beneath station TAG,a thicker crust and high V P/ V S may indicate that materials in the lower crustal are prone to plastic flow,which is responsible for the thickening of the crust.

It is well known that Schr(cid:127)odinger (cid:13)ows to symmetric spaces or, equivalently, Grassmannian manifolds are applied to interpret the geometric properties of the matrix nonlinear Schr(cid:127)odinger equations. In this paper, we deduce Schr(cid:127)odinger (cid:13)ows to the pseudo symmetric space U (2 ; 1) =U (1 ; 1) (cid:2) U (1) and utilize it to give a geometric interpretation of a Manakov system. Combined it with some known results, we then give a uni(cid:12)ed geometric characterizations for a kind of Manakov systems.


Ommi Dental Clinic is a clinic that specializes in dental health services. In running programs, that include patient registration process and data management in Ommi Dental Clinic is still using the manual system, it is not web-based, so it can result in a variety of clinical data records lost or damaged because as noted in the paper only. Data management system that is still done manually, require considerable time and inaccurate, so there are some income or expense that has not been recorded.
Accoding to the issues, it is necessary to build a system that capable to handle data management and variety of other processes it so the clinic�s service could become more optimal and capable of presenting output, either in the form of information and reports accurately and easily.
Ommi Dental Clinic Information System was built using codeigniter framework, the programming language PHP and MySQL database. This information system handles data processing in the form of patient data, data examination or medical record, action data, drug data, payment data and preparing reports in the form of tables and graphs. In addition, the system has an online registration facility. It is expected this information system able to provide convenience to the clinic in data management and able to improve the performance and service towards the patients so that it can be more effective and efficient.


Public key infrastructures (PKIs) are proposed to provide various security services. Some security services such as confidentiality require key escrow in certain scenarios, whereas some others such as non-repudiation and authentication usually prohibit key escrow. Moreover, these two conflicting requirements can coexist for one PKI user. The popular solution in which each user has two different certificates and an escrow authority backs up all escrowed private keys faces the problems of efficiency and scalability. In this study, a novel key management infrastructure called RIKE+ is proposed to integrate the 'inherent key escrow' of identity-based encryption (IBE) into PKIs. In RIKE+ , (the hash value of) a user's PKI certificate also serves as a 'revocable identity' to derive the user's IBE public key, and the revocation of this IBE key pair is achieved by the certificate revocation of PKIs. Therefore the certificate binds the user with two key pairs, one of which is escrowed inherently and the other is not. Furthermore, RIKE+ employs chameleon hash to flexibly control the relationship between the certificate and the IBE key pair. In the case of certificate renewal and revocation, chameleon hash enables RIKE+ to manipulate the hash value of the new certificate, so the user's IBE key pair is not unconditionally changed unless it is necessary. RIKE+ is an effective certificate-based solution compatible with traditional PKIs and can be built on existing X.509 PKIs.


Despite the recent rebirth of scholarly interest in the law of slavery, Kenneth Stampp's The Peculiar Institution contains the best twentieth century overview of the internal law of slavery in the antebellum South. Nevertheless, Stampp's interpretation leaves unresolved the 'dilemma' that he argues also puzzled slave masters, legislators, and magistrates: How the law could recognize slaves both as 'property' and as 'persons.' To Stampp, the 'dual character of the slave' was an irreconcilable contradiction: …there was no way to resolve the contradiction implicit in the very term 'human property.' Both legislators and judges frequently appeared erratic in dealing with bondsmen as both things and persons. Although Stampp states that, 'the slave's status as property was incompatible with his status as a person,' he concludes that 'throughout the antebellum South…legally, the slave was less a person than a thing.'


One of my favorite teachers crafted his lectures like a potter molding clay—not likely into a vase, but rather something more solid and utilitarian, yet still elegant, say, a fruit bowl. Vincent Genusa (Dr. G, we called him) was the only person I have ever known to use the word "prodigious" routinely, referring admiringly to a scientist, or perhaps to the applicability of a particular theoretical method, and he would say it with such relish that sometimes a bit of spittle would be evident, to put it delicately. It was impossible not to be swept up in his enthusiasm as he waxed eloquently about this twisty path to discovery or that sinewy bit of logic, and the fact that I have such vivid memories of his lectures decades later speaks to his artistry.


The following article investigates the interface thermal conductance in a functionalized CNT-epoxy composite system and how does it change with respect to the nature of the surrounding matrix. We have used non-equilibrium molecular dynamics simulations to study the interface thermal conductance in both cured as well as uncured matrix, based on EPON-862 and curing agent-W (DETDA). The functionalization is modeled using a dynamic cross-linking algorithm and represents a realistic model of matrix-ller interface. Our results suggest that the thermal interface conductance increases linearly with the degree of functionalization up to studied 2.5%. In addition, we found that curing of the matrix increases the interface conductance by 20% relative to uncured matrix. It is attributed to relative enhancement in non-bonded interactions (originating from volume reduction) and structural rigidity during curing.
