We describe an investigation focusing on advanced students' and faculty members' reasoning about two questions related to the double-slit experiment with single particles. One question posed was a standard double slit question while the other question was more speculative. First, students in advanced quantum mechanics courses were asked the questions in written form and individual interviews were conducted with six students in which they were asked follow up questions to make their thought processes explicit. We also interviewed five faculty members who had taught modern physics, quantum mechanics and/or solid state physics to understand their reasoning and thought processes. The faculty members' responses shed light on what it means to think like a physicist. Student responses varied greatly in their correctness and sophistication of reasoning, suggesting that even advanced students need scaffolding support in order to learn to think like a physicist.


While the so-called "New perspective in Paul" has been in the focus of New Testament exegesis for more than 25 years now, ancient interpretations of Pauline texts and ideas have been neglected widely. The present volume aims to fill this gap. Its articles concentrate on three different foci of modern exegesis: interpretations of Paul's conversion, his ideas about the relation of "grace" and "works" and the fate of Israel. Several additional articles contrast these ancient perspectives with answers of modern exegesis.


Objective: The Main purpose of this study is to develop a questionnaire to measure positive resources. This study has addressed individuals` positive properties from various angles. Having adopted the viewpoints of Seligman (1990) and Keyes (1998), this study has conceptualized individuals` positive properties on the basis of pleasant life, engaged life, meaningful life and social well-being; and classified social well-being into supporting and sharing. Furthermore this study has added other elements which have been proved to be positive resources through a wide range of studies to the scale items in order to lay a foundation for developing the scale to measure positive resources. Methods: This study was conducted in 3 steps. In the first step, this study has examined a wide range of positive elements through literature research. In the second step, we composed a questionnaire of 199 preliminary items based on our positive factors model and carried out a pilot study with 253 Korean adults[males=103, females=150]. We selected 23 items which had shown high correlation with each total score of sub-factors. In the final step, survey data were collected from 514 who are sampled from Korean adults and 6 dimensions were identified by confirmatory factor analysis through principal components analysis and varimax rotation. The questionnaire`s validity was tested by comparing with Hospital Depression-Anxiety Scale (HDAS) and Satisfaction With Life Scale (SWLS) through Pearson correlation coefficient. Results: The results of this study suggest the reliability of this scale is Cronbach alpha = .86. The results of factor analysis suggest the scale composed with six dimensions. The results of the analysis of convergent and discriminative validity suggest there is a positive correlation between this scale and satisfaction with life [r=.57, p <.01]. and a negative correlation between this scale and hospital depression-anxiety scale [r = - .51, p <.01], which suggests the questionnaire`s validity is acceptable.


This article describes the recent developments in the laboratory compaction of Superpave hot-mix asphalt (HMA). The number of gyrations when mixing the asphalt in a gyratory compactor as correlated to the project traffic level and temperature are critical in order to avoid problems related to durability, rutting, or bleeding. When Superpave was initially adopted, a table was proposed showing 28 possible gyration levels corresponding to seven traffic levels and four temperature ranges. These figures have since been revised twice; included in the article are the three tables demonstrating the ensuing changes. Recent studies have confirmed these changes, reflecting a reduction in the number of required gyrations from 28 to four. Using the lower number of gyrations will result in HMA with higher asphalt content and increased durability and ultimately providing asphalt mixtures with improved overall performance.


Electron vortex beams (EVBs, also known as twisted electron beams) possess an intrinsic orbital angular momentum (OAM) with respect to their propagation direction. This intrinsic OAM represents a new degree of freedom that provides new insights into investigating the dynamics of electron impact ionization. In this communication, we present, in the first Born approximation (FBA), the angular profiles of the triple differential cross section (TDCS) for the (e, 2e) process on CH4 and NH3 molecular targets in the coplanar asymmetric geometry. We compare the TDCS of the EVB for different values of OAM number m with that of the plane wave. For a more realistic scenario, we investigate the average TDCS for macroscopic targets to explore the influence of the opening angle θp of the twisted electron beam on the TDCS. In addition, we also present the TDCS for the coherent superposition of two EVBs. The results demonstrate that the twisted (e, 2e) process retrieves the p-type character of the molecular orbitals, which is absent in the plane wave TDCS for the given kinematics. The results for the coherent superposition of two Bessel beams show the sensitivity of TDCS toward the OAM number m.


Abstract : The USG has not effectively managed interagency collaboration in recent decades. The USG will face complex challenges in the future where it will be necessary to utilize all instruments of national power to their capacity. A coordinated interagency effort must be established and supported prior to U.S. intervention to ensure success. The purpose of this study is to identify challenges and shortfalls in interagency collaboration in order to recommend changes and implementations. The literature supports the concept of expanding interagency organizations like the JIACG to conduct pre-conflict training, execute strategic objectives through tactical means, and maintain reachback capabilities to assist collaboration between DoS and DoD. Using a qualitative method to determine positive and negative aspects of interagency actions, processes, and policies, the selected case studies illustrate the enduring nature of interagency challenges. The results of the case studies show gaps in the whole of government approach that are rectifiable but does not yet have the essential governmental support which is untenable considering the alternative of prolonged interventions, waste of funding, and loss of personnel to conflict. It is prudent for the USG to become more efficient by increasing interagency collaboration to gain maximum utility from the instruments of national power.

This paper examines design characteristics refined over seven years through studies with preand in-service secondary mathematics teachers in the United States. Teachers simultaneously explore big statistical ideas while learning to use a dynamic statistical software tool that is new to them. Most study participants have taken at least one university statistics course, yet surveys, interviews, and content assessments indicate fragile understanding of statistical content, procedurally dominated learning environments, and little use of technology in courses. Important considerations when supporting these learners include respecting the statistical understanding that is present and connecting to it strategically. Productive design characteristics that have been developed and refined include: 1) focusing on big statistical ideas; 2) providing provocative tasks; 3) attending to dynamic technology scaffolding; and 4) implementing sustained intellectual press.


A 37-year-old female patient admitted due to dyspnea on exertion and peripheral edema. For one and a half years, the patient had been taking various drugs and supplements to reduce weight, including amphetamine-like drugs. The patient had no major cardiovascular risk factors except three pack-years of smoking. A chest computed tomography showed a 1.7 cm diameter, capsulated space-occupying lesion in the left ventricle (LV) and 2-dimensional echocardiography showed LV systolic dysfunction (Left ventricular ejection fraction [LVEF], 30%) with a mobile cystic mass (1.1×1.8 cm) that was attached to the LV apex, which was increased in size and number the next day, even with low dose low-molecular-weight heparin. With an increased dose of anticoagulation medication and heart failure management with diuretics and angiotensin receptor II blocker, LV dysfunction was recovered and the LV thrombus disappeared.

Certain porphyry dikes related to a batholithic intrusion in the Blue Mountain area of northeastern Oregon contain irregular segregations of magmatic residuals and veins which are believed to have been caused by the action of the dike magma upon schist inclusions. Many large-scale occurrences similar to this have been recorded, but it is believed that the small size of this magmatic system, dikes less than 2 feet in width, makes it a rather noteworthy occurrence.


The sealing composition contains powders comprised of, by mass, 70 to 90 % aluminium, 5 to 25 % silicon, 0 to 5 % silica and 0.1 to 5 % moderator metal, said powders being dispersed in a carrier comprising an organic binder disolved in a solvent and a mineral binder. The composition is applied to the faces to be assembled of ceramic part and a part made of refractory alloy or super-alloy, and the assembly is heated in order to eliminate said carrier and to form between the two parts a layer of syncrystallized mullite with the ceramic.


We have measured the maps of integrated photon intensity and isochromat photon intensity induced by scanning tunneling microscopy (STM) of noble metal particles on the graphite surface. We have studied the correlation between the contrast of the photon maps with the STM topography. The integrated intensity of the photon map is closely correlated with the height of the topography image. The isochromat photon map changes depending on the wave length of the light collected. This change is explained by the effect of the variation in the tip curvature radius on the spectra of local plasmon. The emission intensity does not change with the size of the Au particle in the range from 3 to 20 nm on the substrate. The tip geometry has an effect on the emission intensity as well as the spectra.


We describe a possible experimental scheme to generate and detect entanglement between charge states in superconducting nanocircuits, discriminating such entanglement from classical correlations. The case of maximally entangled singlet and GHZ states of two and three coupled Josephson junctions is discussed as an example.


A convenient and sustainable protocol for the aerobic oxidation of benzyl alcohols to carbonyl compounds, based on the use of 1,2,4-triazole-type ligands and nickel(II) bromide, is described. This combination leads to the formation of an exceedingly active, enzyme-like system that allows for other oxidative processes, such as benzylic C-H oxidation and oxygen-mediated cleavage of C-C triple bond, a pioneering procedure for transformation of alkynes into carboxylic acids.


The range of techniques for estimating the yield strength of discontinuous rock masses include analytical, numerical and empirical methods and laboratory and field testing. No one technique is definitive. This paper summarises the results from a laboratory based and discontinuum modelling study conducted on discontinuous material with the aim of investigating these techniques from this study, a number of modifications to Bieniawski's RMR system are suggested. These modifications enable the system to provide input data to the Hoek-Brown rock mass yield criterion that better reflect those rock mass properties that most influence rock mass behaviour.


We investigate the wavelength-tuning of cascade quantum-well GaSb-based diode lasers emitting at 3.2 µm. An external-cavity setup is used to demonstrate wavelength-tuning over a range of 250 nm with a maximum output power of 8.4 mW.


It is generally acknowledged that the mass-loss of asymptotic giant branch (AGB) stars undergoes variations on different time-scales. We constructed models for the dust envelopes for a sample of AGB stars to assess whether mass-loss variations influence the spectral energy distribution. To constrain the variability, extra observations at millimetre wavelengths (1.2 mm) were acquired. From the analysis of the dust models, two indications for the presence of mass-loss variations can be found, being (1) a dust temperature at the inner boundary of the dust envelope that is far below the dust condensation temperature and (2) an altered density distribution with respect to p(r) oc r -2 resulting from a constant mass-loss rate. For five out of the 18 studied sources a two-component model of the envelope is required, consisting of an inner region with a constant mass-loss rate and an outer region with a less steep density distribution. For one source an outer region with a steeper density distribution was found. Moreover, in a search for time variability in our data set at 1.2 mm, we found that WX Psc shows a large relative time variation of 34 per cent which might partially be caused by variable molecular line emission.


The paper deals with the relationship between the warming - up duration (5 10 and 15 minutes per group) and the mobility and the hip - joint in the sagital in the frontal plane. The author used the position called 'front splits' in the to bestride lateral in order to find the result he was interested in. The author measured the mobility before and after the warming-up of 288 students, boys and girls, aged seventeen. Some of them practiced sport and some didn't. It was concluded that the mobility was significantly increased by the warming-up. It was also concluded that the mobility of the hip-joint is related to the duration of the warming-up.

ABSTRACT We employed integrated methods to assess the landslide movement in Sv. Anton town in the Western Carpathians Neogene Volcanic Field (Central Slovakia). The integrated diagnostics required study of the landslide kinematic activity by a combination of Global Navigation Satellite Systems (GNSS) and Electrical Resistivity Tomography (ERT) imaging from November 2013 to March 2015. A topographic model with 2-cm accuracy was constructed from Unmanned Aerial Vehicles (UAV) photogrammetry. Continuous spatial datasets of movement and displacement field vectors were interpolated from the measured movements over the entire study period. Although deformation studies in Slovakia have a long-term tradition, complex interdisciplinary studies in urbanized areas are still lacking. This inspired our main objectives: to identify landslide kinematics and to reconstruct and define the rates of annual landslide movement obtained from geodetic measurement at the monitoring points. Our results demonstrate how landslide integrated diagnostics contribute to the detection of slope instability, with a maximum velocity of 60.82 mm/yr during the summer period. The precipitation effects are consistent with the Sv. Anton landslide displacement acceleration, and the following increases in total monthly precipitations are staggering compared to long-term monthly averages: July precipitation increased by 175.3%, August by 203.3%, and September by 198.1%.


Densification of alumina coated with a MgO-Al 2 O 3 -SiO 2 (MAS) glass was investigated from 1400° to 1460°C. Spinel was observed to form at the liquid-alumina interface, whereas mullite crystallized uniformly in the liquid. Spinel and mullite crystallization kinetics were accelerated by smaller alumina particle size. Mullite and spinel crystallization retarded densification by forming a percolating network. Boron doping suppressed spinel formation, and thus alumina sintered to higher densities at low temperature. The concept of glass basicity is proposed as a useful guide for selecting dopants for low-temperature sintering.


The tectonic framework, kinematics and the development of the thrust fault system of the eastern segment of the Mesozoic intraplate Yanshan orogenic belt in western Liaoning province are described in the paper. The tectonic settings and the significance of this fault system have been evaluated following the aforementioned de-scription. The thrust fault system consists of six master thrust faults. Both the northwestern and the southeast-ern faults of them extend east-north-east. The thrust faults between them take, however, the orientation of north-east-north. All these thrust faults tend to be connected together in the northeast and the southwest part respectively. In the northeastern part they tend to get together along the Lingyuan-Dongguanyingzi thrust fault. In the southwestern area they seem to be getting together along Yaolugou-Jinxi fault zone and its coun-terpart , Miyun-Xifengkou fault zone to the west. Structurally all those thrust faults form a tectonic frame-work which looks like a large-scale duplex. Both the geological interrelations and the dating results define a de-velopment sequence of the thrust fault system in this area. The thrusting commenced before Middle Jurassic and reached its deformation peak at the end of Jurassic. The tectonic framework of thrust faults in the area formed as a result of the extensive contraction during this time interval. Top-to-the-southeast movement dominates the thrusting of this tectonic system, which differ profoundly from those thrust faults in the middle and western parts of the intraplate Yanshan orogenic belt in propagation vergence. The spatial and temporal relations be-tween these thrust faults and the east-west trending dextral fault systems in the middle part suggests a unified tectonic model. This model implies that the top-to-northwest thrusting in middle and western part and the top-to-southeast thrusting in the eastern segment of Yanshan intraplate orogenic belt might formed as a result of a right lateral transform deformation along the latitude fault zones.


Software product line engineering is regarded as a promising approach to generate tailored software products

by referencing shared software artefacts. However, converting software legacy into a product line is extremely

difficult, given the complexity, risk of the task and insufficient tool support. To cope with this, in this paper,

we proposed a top-down feature-mining framework to facilitate developers extracting code fragments for

features concerned. Our work aims to fulfill the following targets: (1) identify features at a fine granularity,

(2) locate code fragments for concerned feature hierarchically and consistently, and (3) combine program

analysis techniques and feature location strategies to improve mining performance. From our preliminary case

studies, the top-down framework can effectively locate features and performs as good as Christians approach

and performs better than the topology feature location approach.

The phenomenon of recruitment of foreign scientists after the Second World War figured prominently in the scientific policy of the Peronist government in Argentina between 1946 and 1955, which sought to exploit the German-trained human resources to modernize and increase domestic industrial capacity. The aim of this study is to identify precisely what were the possibilities and limits of that particular strategy in this particular historical moment. If Werner Heisenberg and other outstanding figures who sought to coopt the Peronist government demonstrate the potential implicit in the investment of resources in this policy unprecedented scientific and technological development, the figure of Ronald Richter shows the boundaries of it. Isolated from the scientific community, ultimately, is what gives and takes away the scientific category, the Austrian physicist performance can be contrasted with the now classic analysis of Kuhn on the mechanisms that regulate the so-called "normal science". Through this opposition is seeking to test a possible explanation of how a "fraud" of the proportions of controlled fusion project Richter in the Huemul Island.


In the present article we analyze a textual reference on the birth of a child with physical malformations in Bar Hebraeus' Chronography, the relationship with the descriptions of the Antichrist, and its comparison with previous versions of this legend gathered by Patriarch Michael the Syrian and monk Theophanes Confessor. Our aim is to show the relationship between the three accounts and the possible source used by the two Syriac authors.


The reordering of the international system in the absence of a hegemonic war has revitalized the debate on the nature of international politics, and the continued relevance of the realist paradigm.(2) Critics of the realist paradigm contend that as survival has ceased to be a problem for more developed states, they no longer search consistently for relative gains. Their behavior now can only be understood in the context of international institutions that both constrain states and make their actions intelligible to others.(3) Indeed, some argue that multilateral norms and institutions have made significant contributions toward stabilizing the peaceful transformation of the international system, and that they are likely to become increasingly important in the management of change at the regional and global levels.(4) Multilateralism may or may not supplant the self-help approach and become the dominant mode of interaction among states; there is little doubt, however, that its relevance will further increase, as indicated by the important role of international organizations in post-cold War era conflict resolution.(5) This article will examine the effectiveness and limitations of the Association of Southeast Asian Nations (ASEAN) in coping with the Cambodian conflict.(6) An international accord ending the 13-year-old conflict was signed at a U.N.-sponsored peace conference in Paris in October 1991. Although involving states external to the Association, the conflict threatened the security of at least one ASEAN member and also affected the security of the Southeast Asian region as a whole. As ASEAN has frequently been cited as one of the more successful Third World regional organizations, an investigation of its role and effectiveness in the Cambodian conflict should provide valuable insight into the security roles of regional organizations in general. Current interest in security regionalism may be traced to two major developments. First, the lifting of the Cold War overlay has removed the integrating dynamic and increased the discontinuity between the global system and regional subsystems. Combined with increasing resource constraints, the major powers may no longer have the interest or the capability to become involved in regional conflicts as in the past. While conflicts like the Iraqi invasion of Kuwait may evoke prompt and substantive response, others less consequential to their interests may not. This could shift the burden of addressing regional problems to local states; but it also presents them with the opportunity to gain greater control over their regional environment. Second, the end of the Cold War has invigorated the U.N. Security Council's role of maintaining international peace and security, which could also strengthen the security function of regional organizations. In a report prepared on the instruction of the Security Council summit meeting, Secretary-General Boutros Boutros-Ghali stated: ... In this new era of opportunity, regional arrangements or agencies can render great service ... the Security Council has and will continue to have primary responsibility for maintaining international peace and security, but regional action as a matter of decentralization, delegation and cooperation with the United Nations could not only lighten the burden of the Council, but also contribute to a deeper sense of participation, consensus and democratization in international affairs.(7) Longer-term developments have also made regionalism more attractive to developing states, including their growing political maturity, and the perceived potential of regionalism to promote their economic development and to mitigate their disadvantaged position in the international system.(8) This is not to argue that regionalism will mushroom in every part of the globe. Rather, the general conditions at the systemic and unit levels are becoming more favorable, and the security regionalism option is likely to receive greater attention from the international community. …


In this research, a model-selection criterion for RBFNN under virtual concept drift environments is proposed. Under such environments, the prior distribution of learning samples is changing over time so that online learning tasks usually cause catastrophic forgetting. Such environments are parts of covariate shift. First of all, a statistical model of such environments is constructed. Then, we applied the learning strategies under covariate-shift using the statistical model. The method also provides the model selection criterion. Moreover, several strategies for reducing the computational complexity are also discussed.

Abstract : The numerical solution of certain problems of hydrodynamic forecasting and general atmospheric circulation leads to the solution of the boundary value problem for an elliptical equation for each step and to the transition from step to step using one or another approximation formula. For example, the numerical integration of the vorticity equations in the quasi-geostrophic and the quasi-solenoidal approximations leads to such a procedure. The problem is discussed in the report.


Given the conflicting evidence regarding adenotonsillectomy and the risk of upper airway infections (UAIs), including acute pharyngitis (APT), rhinosinusitis (ARS), and otitis media (AOM), we evaluated the risk of developing UAIs following adenotonsillectomy in a childhood population.


Summary When transplantable mouse sarcomas were infected experimentally with Cl. histolyticum, and the infection controlled by systemic injections of histolyticus antitoxin, the life span of some of the animals was prolonged for as long as 20 days beyond that of the non-infected tumor bearers. But in no instance did the infection completely destroy the tumor tissue. All surviving mice, treated eventually with penicillin in order to eradicate residual infection, developed large sarcomas. Under similar conditions, no such temporary regression was observed for transplantable mouse carcinomas. When a study was made of the effect of histolyticus toxin on transplantable mouse tumors, it was found that systemic (intramuscular) injections of toxin were without effect, whereas repeated local injections of toxin, given either directly into the tumor mass or subeutaneously around the base of the tumor, resulted in marked regression of tumor tissue. But for the toxin preparations used, the effective dose approximated, very closely, the lethal dose, particularly when the toxin wras injected directly into the tumor mass. In no instance was there a permanent regression of the tumor. In tissue culture, carcinoma cells were more resistant to the action of histolyticus toxin than sarcoma cells, just as normal epithelium seemed to be more resistant that stroma cells or fibroblasts. But normal and cancerous epithelium were equally resistant to concentrations of toxin that produced severe damage to sarcoma cells.

This study aimed to describe the procession of the ritual 'Bersih Desa' and analyze the existence of the sacred dance 'Topeng Kona' as a tool for validating the ritual 'Bersih Desa' in Blimbing Village, Bondowoso Regency, East Java, Indonesia. The intelligence and local wisdom possessed by the ancestors of Blimbing Village, was able to give birth to masterpieces of high noble value in the ritual 'Bersih Desa', such as 'Topeng Kona' dance, 'Singo Ulung' dance, Tandhe' Bini' and 'Ojhung' dance. The masterpiece was the result of the marriage of two cultures, namely Javanese culture (represented by the figure of Juk Seng or Juk Singo Ulung) and Madurese culture (represented by the figure of Juk Jasiman). The result of the marriage produced a migrant culture with a high value that differed from the culture of the migrant's home region. The sacred dance 'Topeng Kona' was used as a medium to validate the ritual 'Bersih Desa' as a form of appreciation for Jasiman figures who came from Madura and became the member of the residents of Blimbing Village.

Due to the absence of energy transmission lines connected to the water pumping sites in remote areas, problems related to the electrical power outages and the environmental degradation caused by fossil fuel. For this one of the most conceived solutions is the photovoltaic water pumping technology which has the advantage of being sustainable and respectful of the environment to supply water to rural areas. To ensure the need of water, especially for domestic use and small communities, in this article, the photovoltaic energy system for autonomous water pumping using the induction motor was presented, particularly adapted to the isolated regions. Pumping system consists of four photovoltaic (PV) panels, boost converter, inverter, induction motor, centrifugal pump and a storage tank. In this study, the output power of a PV solar cell is fully used by proposing the P&O algorithm, where it is used to follow a maximum power point tracking (MPPT) technique. The recommended system is designed, modeled and simulated on the MATLAB/Simulink platform. The efficiency of the proposed algorithm is observed with variable solar sunshine.

Introduction Fungicides are pesticides that have potential toxic effects on animals. They have a wide range of usage area and are used for protecting tubers, fruits and vegetables during storage or are applied directly to ornamental plants, trees, field crops, cereals and turf grasses in agriculture (1). In industry, numerous fungicides are used to protect products during shipment, suppress mildews that attack painted surfaces, preserve wood, control fungal growth in paper pulps, and protect household carpet and fabric (2). In veterinary medicine, fungicides are commonly an antibacterial/antiseptic treatment for foot rot disease but, some fungicides, are also used a molluscicide to repel and kill slugs and snails (3). Both alkyl and ethylene dithiocarbamates form salts with metals and both can be oxidized to the corresponding disulfides. Dithiocarbamates may decompose under certain circumstances into a number of compounds, such as sulfur, 5, 6-dihydro-3 Himidazol [2,1-C]-1, 2, 4 dithiazole -3-thione, ethylenethiourea (ETU), andethylenediamine (EDA). ETU stable, has high watersolubility, and is of particular importance because of its specific toxicity (4,5). Ethylenebisdithiocarbamates (EBDCs) are widely used in agriculture as fungicides, mainly on fruit, vineyard, and potato crops. Their extensive world-wide consumption can be ascribed to their low acute toxicity and their short environmental persistence (6). Mancozeb is one member of ethylenebisdiothiocarbamate (EBDC) fungicides. EBDC pesticides because of health concerns caused by ETU, including potential carcinogenic, developmental and thyroid effects (7). It uses to protect many fruit, nut, and field crops from a wide spectrum of fungal diseases (4). Mancozeb is effective in soils with ETU 5-10 days. (4). In our study, investigation the histopathological effects of mancozeb on intestine tissue of zebrafish (Danio rerio) were aimed. The zebrafish is a small fish about 6cm in length and characterized by a series of five pigmented stripes running the entire length of each side of its body. The zebrafish are used as stress test model because they can survive fairly severe environmental changes without succumbing, surviving long enough to show developmental defects. Finally, easy and inexpensive raising making them an ideal animal model for researches. Materials and Methods Zebrafish were raised in a incubation chamber, and received 14 hours of day light and 10 hours of darkness every day. After one week adaptation period, zebrafish divided into four groups (n=10) as one control and 2 experimental groups (5 ppm, 7.5 ppm). For investigating the effects of mancozeb, intestine tissues were dissected after 5 days of the exposure. Tissues were fixed with 10% neutral buffered formalin and dehydration were carried out in an ascending series of ethanol. After tissues were cleared in xylene, embedded in paraffin wax and cut into 5 μm sections on a microtome. The sections were stained with hematoxylin (H&E) and results were evaluated with light microscope. Results In control and experimental groups any death and behavioral changes were not observed. In control group, normal intestine histology was monitored. Mucosa, submucosa and serosa layers and lamina propria were observed clearly (Figure 1a). Villi structures and goblet cells were easily monitored. Cell layers of mucosa epithelium and goblet cells between enterocytes which have columnar nucleus were photographed (Figure 1b). In 5 ppm mancozeb exposure group, degeneration, disjoined and enteritis formation at villi structure were detected (Figure 2a). Expansion and increase in the number of goblet cells were monitored (Figure 2b). Contraction at lamina propria and expansion at villi structure were observed (Figure 2c). In addition, dysplasia and increase in the number of lymphocytes at villi were found (Figure 2d).

There is a growing recognition of the need to expose marketing students to the topic of bargaining. A new win-win model of distributive bargaining and a mixed motive structure of the buyer-seller situation provides a logical framework for introducing bargaining into marketing.


Highly ordered MCM-41 materials were synthesized using single or mixed alkyltrimethylammonium and alkyltriethylammonium surfactants of alkyl chain lengths from 12 to 22. As determined using combined adsorption/powder X-ray diffraction (XRD) analysis, the obtained samples exhibited pore sizes from 3.2 to 4.8 nm with about 0.3 nm increments. Nitrogen adsorption isotherms for the samples under study exhibited remarkably sharp capillary condensation steps. The adsorption isotherm for the highly ordered 4.8 nm MCM-41 featured a narrow hysteresis loop with parallel adsorption and desorption branches. This behavior is probably a feature of nitrogen adsorption in ideal cylindrical pores of this size and is distinctly different from the previously reported behavior of MCM-41 with pore sizes in the range 4−5.5 nm, which had triangular hysteresis loops on their nitrogen adsorption isotherms. All MCM-41 materials had remarkably narrow pore size distributions, which showed that fine-tuning of the pore size is easily a...


This study aims to empirically examine how the Khmer Rouge regime (1975–1979) in Cambodia continues to affect the health of the second generation.,The 2000 and 2005 Cambodia Demographic and Health Surveys were used in the analysis. The study sample were women with a child/children in 2000/2005. The sample population was identified according to whether the person was in utero "91 months or earlier before the Khmer Rouge regime," "46–90 months before the Khmer Rouge regime" and "1–45 months before the Khmer Rouge regime" and during the Khmer Rouge regime. The authors then regressed the size of babies of the targeted population on the timing of the mothers being in utero.,Mothers who were in utero during the regime had a higher likelihood of giving birth to smaller-than-average babies. Additionally, mothers born in the areas that had a higher probability of death of children aged five or under during the regime were at risk of giving birth to smaller-than-average babies if they were in utero during that time.,The findings have significant implications for today's society in practice, which still has a considerable number of people suffering from civil conflict and malnutrition. Civil conflicts not only severely affect current, but also future generations.,This is the first paper to assess the impact of the Khmer Rouge regime on the health of the second generation.

PURPOSE: An apparatus and a method for controlling directly a local inductance of a coaxial parallel antenna type plasma source are provided to distributes uniformly RF power to each antenna and form uniformly density of plasma by controlling the amount of current on an antenna. CONSTITUTION: An antenna is formed with an antenna coil(31), a dummy load(32), a control bar(33), and a current controller(34). The antenna coil(31) receives electric power from an RF(Radio Frequency) power source and an interface network. The antenna coil(31) has a spiral shape. The dummy load(32) is installed in a predetermined interval in an inside of the antenna coil(31) in order to change a path of current. The current controller(34) is located on the dummy load(32). The current controller(34) shifts a position of the control bar(33) by controlling the control bar(33) and changes the path of RF current thereby.


Blunt trauma to the thorax can on rare occasions lead to early severe hypoxemia from pulmonary contusions; more commonly, the hypoxia associated with pulmonary contusions is most pronounced hours to days after the initial injury. Extracorporeal membrane oxygenation (ECMO) has been used as a salvage therapy in these patients who have failed conventional ventilator strategies. While the uses for ECMO in the non-acute setting continue to expand, the use of ECMO in trauma has stagnated and remains controversial, despite studies reporting survival rates between 50% and 79% [1-3]. Risks such as hemorrhage, thrombosis, and limb ischemia, as well as physician unfamiliarity with ECMO technology, serve as barriers to the widespread use of ECMO in trauma patients [4]. In this report, we describe a patient with severe pulmonary and myocardial contusions producing refractory hypoxemia and hypotension, along with intracranial hemorrhage. The patient was quickly treated with veno-arterial ECMO for cardiopulmonary support and was stabilized and eventually discharged with minimal functional deficits.


Abstract Single crystals of (I) BaCu0,41Pr2Mo4O16 and (II) BaYb2Mo4O16 have been prepared by flux technique. Both compounds crystallize with monoclinic symmetry, space group C62h-C2/c with (I): a = 5.352(11), b = 12.888(2), c = 19.399(4) Å; β = 90.89(3)°; (II): a = 5.181(7), b = 12.467(3), c -19.350(3) Å , β -91.93(2)°, Z = 4. The crystal structure is characterized by 1∞[BaMO12]-chains along [010]. In the first case the M positions are occupied by copper by about 41%, in the second case these positions remain completely unoccupied. With respect to the crystal chemistry of the reference compound Ba(Cu0.22Mg0,78)Nd2Mo4O16 all substances of the composition BaLn2Mo4O16 should be written as Ba▪Ln2Mo4O16 indicating the holes in the 1∞[BaMO12]-chains by ▪.


The database on gender access in 64 USAID-assisted countries is described for the following variables: enrollment in formal education education attainment and illiteracy education expenditures education resources and socioeconomic and demographic indicators. Analysis of quantitative data is conducted for trends in the 64 countries. Analysis of qualitative data is performed for Mali Yemen Nepal Sri Lanka and Indonesia for the following: country background history of the educational system current participation and opportunities for women disparity between male and female access to education quality of the data explanations for the disparity and policies to increase womens access to education. The regional distribution of the countries was the following: 16 East African 17 West African 4 North African 4 Southeast Asian 5 South Asian 6 Southwest Asian 11 Latin American and 1 Oceania. The objective of constructing a data base was to provide accessible data for analysis of gender-access information for comparisons of access and disparity. Some preliminary conclusions are that wide disparities existed in 1975 between countries and within regions. Primary education attendance was several times higher than secondary education attendance and 8 times higher than higher education attendance. Gender differences were greater in primary education compared to secondary education and greater in secondary education compared to higher education except in Latin America and the Caribbean. There is a greater likelihood that men will outnumber women as educational level increases. The gender differences are greatest in higher education. Between 1975 and 1983/84 higher education and secondary education expanded more than primary education; female enrollment increased by 49% in primary education (37% for men) and 71% in secondary education (48% for men). The increases did not compensate for the disparities. Morocco Nepal and Guatemala increased access while Senegal increased disparity. Countries with high access spend more of their gross national product on education than low access countries with low access and disparity have lower infant mortality.


In this paper we propose a collaborative distributed denial of service (DDoS) attack mitigation scheme using SDN. We design a secure controller-to-controller (C-to-C) protocol that allows SDN-controllers lying in different autonomous systems (AS) to securely communicate and transfer attack information with each other. This enables efficient notification along the path of an ongoing attack and effective filtering of traffic near the source of attack, thus saving valuable time and network resources. We developed and deployed a prototype of the proposed scheme in our lab to evaluate the performance and efficiency. Based on the experimental results we showed that our SDN based collaborative scheme is capable of efficiently mitigating DDoS attacks in real time with very small computational footprints.


Today, aircraft are vital to the world economic development, however they require an
important quantity of fuel to power flights. One way of reducing fuel burn during a flight is to
provide a flight reference trajectory that requires minimal fuel consumption. At the Research
Laboratory in Active Controls, Avionics and Aeroservoelasticity (LARCASE), an algorithm called
the beam search algorithm was implemented to find the most economical combinations of
speeds and altitudes for the vertical reference trajectory. Observations showed that, in most
cases, the algorithm was able to find the optimal solution, which provided fuel savings of up to
2.99%.


Eric Temple Bell, the mathematician and biographer of mathematic ans, believed that Fermat's last theorem would be one of the questions left un resolved when human civilization de stroyed itself in nuclear war. Bell made this prediction shortly before his own death in 1960. If he had lived a few decades longer, it is an interesting question whether he would have been more surprised at humanity's continu ing survival or at the announcement, on June 23,1993, of a proof of Fermat's last theorem. The theorem itself is easily stated. Pierre de Fermat asserted that if a, b and c are integers greater than 0, and if n is an integer greater than 2, then there are no solutions to the equation:


We study a class of Legendrian surfaces in contact five-folds by encoding their wavefronts via planar combinatorial structures. We refer to these surfaces as Legendrian weaves, and to the combinatorial objects as N-graphs. First, we develop a diagrammatic calculus which encodes contact geometric operations on Legendrian surfaces as multi-colored planar combinatorics. Second, we present an algebraic-geometric characterization for the moduli space of microlocal constructible sheaves associated to these Legendrian surfaces. Then we use these N-graphs and the flag moduli description of these Legendrian invariants for several new applications to contact and symplectic topology.
Applications include showing that any finite group can be realized as a subfactor of a 3-dimensional Lagrangian concordance monoid for a Legendrian surface in the 1-jet space of the two-sphere, a new construction of infinitely many exact Lagrangian fillings for Legendrian links in the standard contact three-sphere, and performing rational point counts over finite fields that distinguish Legendrian surfaces in the standard five-dimensional Darboux chart. In addition, the manuscript develops the notion of Legendrian mutation, studying microlocal monodromies and their transformations. The appendix illustrates the connection between our N-graph calculus for Lagrangian cobordisms and Elias-Khovanov-Williamson's Soergel Calculus.


A total of 112 samples were collected from Busia Township and Angurai sites in Busia and Teso Districts respectively. These comprised 25 from Busia and 87 from Angurai in two sampling dates, 2002 and 2004 to determine soil fertility change over the two year period. In order to assess the soil fertility from the sites, and in different land uses, soil chemical and texture analysis was carried out and values compared with crop recommended agronomically adequate values for specific elements. Texture for purposes of soil hydrologie behaviour was also considered in respect to soil water. Average organic carbon in the soils was 1.39% with mean in Busia and only 64% of the farms had adequate levels of carbon. In Angurai site, mean organic carbon increased over the two year period from 1.13% to 1.41% with the number of farms with adequate (moderate) levels increasing from 13% to 35%. However, overall carbon levels were still below threshold levels during the two sampling intervals. These levels of nitrogen indicated that the soils were very low in organic matter as revealed by the analysed total nitrogen, which ranged from very low to just moderately adequate. Generally the sites showed low soil fertility status as indicated by the soil organic C, total nitrogen, available phosphorous and soil PH. Exchangeable potassium was adequate in the two sites although the second sampling (after two years) in Angurai showed slightly low but above threshold levels of the same. Available phosphorous was very low to sustain optimal crop yield in both sites even after two years sampling interval (in Teso District). 96% of points in Busia and 89% of points in Angurai and 80% of points after second sampling same site had deficient levels of available phosphorous. Some farms within the sites were applied phosphate fertilizers at planting time while others received no fertilizers. Majority of soils from these sites were also found to be strongly acidic thereby limiting availability of phosphorous. In these situations, phosphorus tends to be "fixed" by the soil. The low available P levels needs to be corrected through application of 100kg/ha of triple super phosphate or compound fertilizer containing N, P and K at planting time and top dress with 80kg/ha CAN. Acidifying fertilizers like diammonium phosphate (DAP), ammonium sulphate (AS) or ammonium sulphate nitrate (ASN) should be avoided due to their acidifying reaction. Alternatively, agricultural lime need to be applied at a rate of 2t/ha one month before planting. Exchangeable potassium (me%) was on average adequate but there were a good number of sites, which were K deficient and required K replenishment for balanced crop fertilizer application. Two year sampling interval in Angurai led to an increase in the points with potassium deficiency from 24% to 29%. It is recommended that in Busia site and Angurai in Teso District, compound fertilizer containing nitrogen, phosphorous and potassium e.g. N: P: K 17:17:17 at 300kg/ha per year should be used at planting to correct N, P and K deficiencies in the soil. All the sites in Busia and Angurai (will) will require application of 5t/ha FYM or compost on sites with crops to raise soil organic matter and hence total nitrogen. In Angurai site foliar feed containing zinc, should be sprayed on crops. On the effect of time interval on soil fertility status in Teso District, it can be concluded that farming activities at this site led to change in soil fertility status and almost coincides with the KARI-NARL recommendations that oil should be resampled after very three years. Most of the land (60%) in Busia is under bushland/ grazing land/ grassland/fallow and least under nappier grass indicating most farmers here practice with free range grazing and limited zero grazing. Land under crops is just 36% of the land implying that farmers are slowly 2 adapting crop farming. The most important crops in Busia are maize (18%) and sweet potatoes (12%) followed by cassava (8%). In Angurai site during the first sampling, 83% of the land was under crop farming with the rest under bush/fallow while during the second sampling (2004), only 64% was under cultivation. Only 18% of the farms were fallow/bush for grazing. There was pure groundnut and groundnut intercropped with maize. The nitrogen fixed by groundnuts benefit the maize crop. The %sand, %silt and %clay indicated that soils taken from these two sites had a mean textural class of sandy loam (SL) even after an interval of two years sampling in Angurai. This texture implies that the soils have been subjected to erosion and hence the low %clay range of 5.8-57.3 % clay for Angurai and 11.1-41.2 % clay for Busia. Soil texture can only change due to erosion as both water and wind erosion would take away the fine particles first leaving large particles. (Resume d'auteur)


Abstract The domain structure of ferroelectric ceramics changes in the process of polarization and usage. This kind of change has a direct influence upon the macroscopic qualities of the materials. A simple method for determining quantitatively the fraction of 90° domain-rotation in the tetragonal ferroelectric phase by measuring the changes of the intensity of the diffracted x-ray lines has been put forward in this article. The percentage of 90° domain-rotation in the polarization process will be obtained directly when the intensity ratios of 1200 and 1002 of the nonpolarization and polarization, respectively, .me measured correctly. The structure factors and preferred orientation which may exist have been considered in the derivation of the formula. For PZT ceramics of 50/50 Zr/Ti the fractions of goo domain-rotation under three different conditions of polarization have been computed using the above method. As the degree of polarization Is increased, the amounts of the 90° domain-rotation are 09.6%, 27....


Reconfigurable Intelligent Surfaces (RISs) have gained immense popularity in recent years because of their ability to improve wireless coverage and their flexibility to adapt to the changes in a wireless environment. These advantages are due to RISs' ability to control and manipulate radio frequency (RF) wave propagation. RISs may be deployed in inaccessible locations where it is difficult or expensive to connect to the power grid. Energy harvesting can enable the RIS to self-sustain its operations without relying on external power sources. In this paper, we consider the problem of energy harvesting for RISs in the absence of coordination with the ambient RF source. We consider both direct and indirect energy harvesting scenarios and show that the same mathematical model applies to them. We propose a sequential phase-alignment algorithm that maximizes the received power based on only power measurements. We prove the convergence of the proposed algorithm to the optimal value under specific circumstances. Our simulation results show that the proposed algorithm converges to the optimal solution in a few iterations and outperforms the random phase update method in terms of the number of required measurements.


Adhesive joints have been widely used in the automotive and aerospace fields in order to reduce the weights of products. The strength of adhesive joints, accordingly, needs to be increased and their behaviour should be predicted in order to achieve accurate designs. Studies to improve the strength of adhesive joints via surface treatment methods or by using two adhesives with different mechanical properties have been conducted. Various modeling methods also have been studied to predict the behaviour of adhesive joints. Unfortunately, the relationship between the bonding surface roughness and adhesive joint strength needs to be further clarified in order to be applied in practical design. As analyzing the relationship through a conventional finite element method assuming perfect bonding is challenging, the behaviour of the adhesive joints may be analyzed using a cohesive zone model or interface modeling methods from an integrating released energy point of view. The strength of adhesive joints can be improved via micro-patterning due to the mechanical interlocking effect. Therefore, in this study, a micro-pattern was fabricated to improve the strength of adhesive joints. Various pattern-sized single leg bending joints and end notched flexure joints were manufactured and experimented upon. In this study, characteristics of each pattern surface were independently classified and modeled with a cohesive zone model. Finite element analyses were then performed and simulation results were compared with experimental results. The numerical results satisfactorily describe the experimental results, and failure loads were predicted with a maximum relative error of 8%. From these results, it may be concluded that the present findings can be applied to practical design and that the failure load can be predicted via a finite element analysis.

Imaging studies showed a large tumor in fourth ventricle. We did suboccipital craniotomy with tumor removal. Pathologic study revealed atypical CPP. Based on our knowledge, up to now, this patient is the first atypical CPP case of fourth ventricle in Korea.


Objective:To investigate the beneficial effects of inchinkoto (ICKT) in the liver after 70% hepatectomy following ischemia reperfusion. Methods:Wistar rats were divided into 3 groups: simple laparotomy and 70% hepatectomy (Hx), 70% hepatectomy following ischemia reperfusion (IR) with vehicle (IRHxV), 70% hepatectomy following IR with ICKT (1 or 2 g/kg of body weight; IRHxK). Vehicle or ICKT was administered for 3 days preoperatively. The hepatoduodenal ligament was clamped for 15 minutes before hepatectomy in the IRHx groups. Rats were killed 1 hours after hepatectomy. In other experiments, the hepatoduodenal ligament was clamped for 30 minutes, with or without ICKT treatment, to evaluate the effect of ICKT on IR injury-induced mortality. Serum transaminase levels and the gene expression of inflammatory cytokines and inducible nitric oxide synthase in the remnant liver were determined. Furthermore, the expression of antioxidant genes was evaluated by PCR array. Results:The elevation of serum transaminase levels, the upregulation of genes for inflammatory cytokines and inducible nitric oxide synthase, and the increased formation of nitrotyrosine observed in the remnant livers of the IRHxV group were all significantly attenuated by preoperative administration of ICKT in the IRHxK group. The expression of antioxidant genes was also higher in the IRHxK group compared with that of the IRHxV group. Moreover, administration of ICKT significantly reduced the mortality induced by IRHx after 30-minute ischemia. Conclusions:Preoperative administration of ICKT provides beneficial effects through attenuating inflammatory responses and oxidative stress in the liver following IR and subsequent hepatectomy.

This study is to design a novel septic tank, named Anaerobic Upflow Domestic Septic Tank (AUDST) to recover biogas as energy and treat domestic sewage. The green technology proposes alternate options to existing Domestic Septic Tanks (DST), encourages anaerobically pre-treatment to reduce bacteria, pollutants, Total Suspended Solids (TSS), Chemical oxygen demand (COD) and Biological oxygen demand (BOD) before the effluent is discharged or is removed by cesspit trucks. Studies have shown that DST in homes partially treat or just store sewage. Again, these DST have to be emptied from time to time because it lack features that will sustain anaerobic activity and usually the sludge is disposed of directly into the sea, water bodies and even into open places such as "Lavender Hills" without any treatment or disinfection. These practices cause severe public health and environmental problems. To tackle the challenge at household level, DST are redesigned to treat domestic sewage with less management, low operating cost, low secondary discharge of pollutants. The proposed new design concept is operated through three (3) units: such as desilting, anaerobic digestion and facultative filtration units. The anaerobic digestion stage is made up of baffle and anaerobic filter for accommodating sludge and providing a more intimate contact between anaerobic biomass and sewage which improves treatment performance. The anaerobic unit is fitted with locally woven baskets prefilled with packing materials. The aim is to strengthen the biological treatment process at this stage. The Facultative Filtration unit of the model is also packed with filtering media such as gravels (3-6mm in diameter) that is low in cost, and has a high durability to produce effluent with lower pollutants and suspended solids content to meet Ghana's Environmental Protection Agency (EPA) standards for the discharge of domestic effluents. 1Energy and Environmental Engineering, University of Energy and Natural Resources, Ghana 2Department of Chemical Engineering, Kwame Nkrumah University of Science and Technology, Ghana *Corresponding author: email@example.com


Lewis acid-assisted sulfonylation of anisole with [ 35 S]methanesulfonyl chloride afforded high specific activity aryl [ 35 S]sulfones. Demethylation and treatment with triflic anhydride gave the versatile [ 35 S]triflate 1 in good overall yields. The [ 35 S]sulfone triflate could be further functionalized by catalyzed aminations, Stille couplings, and cyanation.


Now a day, the bimetallic sheet in metal forming processes are highly requested due to their characteristics and better mechanical properties than a single sheet. Unfortunately, the spring back phenomenon is one of the most phenomena that greatly affecting the dimensions and geometry of the V-bending process of the bimetallic sheets. For this purpose, the present work was conducted to study experimentally and numerically the effect of process parameters on spring back of Al/Cu bimetallic sheet in Vbending process includes the sheet thicknesses, equal punch and die radii, and strain rates. Firstly, it was proved that experimentally and numerically the setting position of Al die face/ Cu punch face setting condition experienced a smaller spring back value. In general, good agreement between experimental and numerical results was observed. Both results illustrated that positive and negative spring back are occurred due to changes in punch and die radii and sheet thickness, and with increasing their values the negative spring back is changed to the positive one as well as increasing the amount of spring back too. Also, with increasing the strain rates the amount of the spring back has either increased or decreased are greatly affected by sheet thicknesses and radii of the punch and die. Moreover, ANOVA analysis was conducted to determine the relative contribution and main effect of the process parameters on spring back. The ANOVA analysis shows that the bimetallic sheet thickness and punch and die radii are the significant parameters with P-value less than 0.05, while the strain rate is not a significant parameter, and has less influence on spring back than the other two parameters. Furthermore, a validated simulation model was developed to study the effect of using the die with a circular groove and the process temperature on spring back of the Al/ Cu bimetallic sheet. The simulation result provided that a die with a circular groove was experienced a less amount of spring back compare with simple V-die process and results in reducing the spring back amount in Vbending process of the bimetallic sheet. Also, the spring back amount is decreased by increasing the temperature in the Vbending process. Index Term-Vbending, Al/Cu bimetallic sheet, spring back, process parameters, FE simulation, ANOVA analysis.

[1] The transport dynamics of burnt material in fluvial systems require attention since the off-site transfer of soil material from wildfire-affected slopes includes ash and nutrients which may have negative impacts on downstream water quality. The aim of this work is to explore the presence, structural characteristics, and fluvial behavior of fire-modified soil aggregates in burnt soil material sampled from a water supply catchment near Sydney, Australia, and to compare their fluvial behavior to that of composite particles from unburnt soils. Samples of burnt and unburnt soil material were analyzed for effective particle size, settling velocity, composite particle density, and porosity using established microscope-based image analysis approaches. Burnt soil aggregates exhibit significantly higher settling velocities (mean 11.47 ± 1.11 mm s−1) than unburnt particles of similar diameter (3.36 ± 0.91 mm s−1) reflecting an increase in density because of reduction in organic content and a reduction in pore space linked to shrinkage. Soil aggregates in severely burnt soil are dense and inorganic and behave differently to their unburnt counterparts and discrete grains of the same size. Burnt composite particles are robust and readily transported within fluvial systems. Their presence in burnt soil and mobilized material is likely to have important implications for postfire fine (<63 μm) sediment and nutrient budgets.


Abstract Lubricanting greases from waste frying vegetables oils with natural fibers additives could be the answer to the sustainable production of greases. Also, their biodegradability makes them more acceptable for the environment, having in view increasingly strict regulations in domain. In this experimental work, twenty lubricant formulae were created from waste sunflower oil and waste palm oil with calcium or lithium stearate as thickener and cellulose or lignin additives. All were rheologically tested and characterized as Bingham fluid with good consistency and plasticity. The penetration tests confirmed the good consistency, categorizing these products from normal to firm, very firm and hard lubricant greases comparable to those conventionally obtained from mineral oils.


Non-contact methods for testing system-on-chip (SoC) and system in package (SIP) assemblies are presented. This method allows for high speed testing at the wafer level for SoCs as well as testing during and after assembly for panel or wafer level SIP technologies. Wafer testing at advanced nodes is carried out without damaging underlying metallurgy - an issue with current contact testing techniques. The technology utilizes non-contact GHz short-range transceivers to transfer test signals and results to and from SoC ICs. The wireless probes convert standard tester ATE logic levels to high frequency RF (GHz) transceiver signals and thus allow the use of standard test equipment. A reduced set of contact probes are used for test power only. A 45 nm fully CMOS compatible IC with wireless test transceivers is designed and fabricated. Enhancing the reliability and economics of IC manufacture by enabling non-contact testing of SoCs before and during packaging is a key benefit of this technology.

A framework for testing web applications basing on web serv ic s is presented. The framework uses a formal specification of the tested system in form of XQPN net, a colored Petri net allowing manipulati on of XML data. Tests of real application are driven by transitions in X QPN net. After performing transitions in the XQPN model and corresponding ca lls to the tested system, the equality between the states of model and teste system is checked. The paper describes XQPN nets and its application in modeling of web applications and presents architecture and main components of the framework.


By integrating the exact equations of motion, particle orbits have been followed in a good model magnetospheric field consisting of a planetary dipole, forward magnetosphere, and magnetotail current system. Proton energies from 2 eV to 20 keV were used for the full range of equatorial pitch angles and phase. Despite considerable pitch angle scattering in the equatorial plane crossings, it is found, first, that the bounce-averaged cross-tail drift velocity is approximately independent of pitch angle. Second, it is found that, averaged over initial gyrophase, the drift velocity (due to field curvature and gradient) is proportional to proton energy and is given to good approximation by adiabatic approximations, even up to 20 keV, despite the extreme lack of meeting the adiabatic criteria.

Realistic modeling of dense pre-graphitic carbons is a prerequisite for the fine understanding of their properties. High Resolution Transmission Electron Microscopy (HRTEM) allows to get valuable 2D information about the atomic structure of such carbons. However, HRTEM is 2D by nature while the observed structures are 3D. Obtaining 3D representations of such materials would be a great help in the process of full 3D atomic structure modeling. We propose an approach which aims at synthesizing 3D image data from 2D HRTEM images using a novel analysis/synthesis framework. The analysis step consists in computing reference statistics on the subbands of a HRTEM sample decomposed using a steerable pyramid. In the synthesis stage, through an iterative and multiscale scheme, these statistics are imposed in 3D on the subbands of a random 3D data block. The inference from 2D reference statistics to 3D target statistics is done using the property of orthotropy typical of pre-graphitic carbons. Synthesis results obtained from HRTEM samples with increasing structural order are provided which show the relevance of the synthesis scheme.


'George and Lynne' is a comic strip which appears each day in one of Britain's most popular newspapers, The Sun. The central characters are an affluent married couple living in a spacious house on the banks of a river. George has an executive (though unspecified) position with a commercial organisation and Lynne, who has no children to look after, stays at home. They have a large number of friends, plenty of clothes and other material possessions, and enjoy a happy marriage and active social life. As portrayed in the strip their lifestyle, as we shall see below, is an expression of contemporary consumer culture and in particular a celebration of the naked (or almost naked) human body (Featherstone 1982).


Electron number density behind a laser supported detonation (LSD) wave was measured by the two-wavelength Mach Zehnder interferometry. As a result, the density was maintained at about 2×10[/m] during the LSD regime in 2D and quasi-1D blast wave expansion conditions. It suggests that this is a critical density necessary to sustain LSD in atmospheric air by CO2 lasers. Temperature was estimated at 12000~15000 K assuming local thermal equilibrium. Deduced absorption length was at 0.10~0.13 mm. It suggests that the laser was absorbed in a very thin region of the plasma layer.

A combination radiant-flux regulator for a high-temperature solar plant with paraboloidal concentrator is considered. It takes the form of two shielding cylinders operating simultaneously, an outer and inner shield; it permits regulation of two parameters, the radiant-flux density at the focus and the power of the solar plant. An experimental model of the controller has been tested.


The soaring costs of designing and manufacturing application specific integrated circuits have motivated the use of flexible solutions in the form of programmable architectures. Such solutions amortize the upfront design and manufacturing costs by utilizing the design for multiple applications. However, existing methodologies to design these programmable architectures are not equipped to target programmable architectures ranging between hardwired data paths and RISC/VLIW processors. These sub-RISC architectures are interesting because many applications benefit from customized networks of special purpose functional units and distributed memories. A particular sub-RISC alternative to assemblages of RISC or VLIW processing elements is an architectural style based on point-to-point networks of statically-scheduled, horizontally-microcoded processing elements called TIPI (Tbiny Ibnstruction Pbrocessors and Ibnterconnect). TIPI architectures provide programmability on top of customized data paths without imposing restrictions on the data path style. A new methodology and framework called the TIPI approach has been developed to address these architectures. The TIPI approach is enabled by three key aspects. First, the description of a data path as a set of atomic actions simplifies the design process by removing the need to specify control. Second, design productivity is gained by replacing the specification of the instruction set with a technique that automatically extracts a set of unique orthogonal operations and a conflict table that completely define the data path's programmability. Third, a single underlying model based on the data path, data path constraints (programmability constraint ), operations, and conflict table enables the use of multiple views (architecture, operation, simulator, hardware, assembler, disassembler, and compiler) to allow each facet of the design to be captured in a natural way while maintaining consistency between the views. Results indicate the framework facilitates rapid design, analysis, implementation, and programming of TIPI architectures. Besides providing a methodology and framework to more easily design and achieve higher performance designs, TIPI processing elements and the TIPI approach are poised to address future work on the emerging issues of power, variability, and reliability at the architectural level. Finally, the ease of decoupling and composing TIPI processing elements has motivated ongoing work to develop a methodology for designing low-overhead multiprocessor architectures.


Identity cues can impact levels of comfort for marginalized individuals in various contexts, including STEM fields and medical spaces. In this study, we examined whether a therapist's personality and race can serve as identity cues for racial/ethnic minority clients and affect the therapeutic relationship. We recruited Asian American and Hispanic/Latinx women (N = 260) for a 3 (trait: high agreeableness, low agreeableness, control) x 2 (race: Black, White) between-subjects experimental study to test the effects of a therapist's race and personality traits on women's expectations for a therapeutic relationship and anticipated prejudice from the therapist. We found that racial/ethnic minority women anticipated a more genuine relationship, F(1, 252) = 10.36, p = .001, ηp2 = .04, with a Black female therapist and perceived her to be more culturally competent, F(1, 252) = 20.04, p < .001, ηp2 = .07, and less likely to be racist, F(1, 252) = 12.68, p < .001, ηp2 = .05, than a White female therapist. We found no significant differences in perceived prejudice based on the therapist's personality. Similarly, there were no significant differences in expectations for the therapeutic relationship based on therapist personality.

The objectives of the research herein are to detect if the modifications of sFlt-1 and PlGF can be correlated with the clinical and biochemical status of the hypertensive pregnant woman and if the sFlt-1/PlGF ratio is a good predictor for preeclampsia in case of the investigated patients. In the study herein, 100 pregnant women were evaluated; they were distributed in the following groups: The group of pregnant women diagnosed with HTN at the time of hospital admission � including 50 pregnant women, of which 16 pregnant women presented medium and severe forms of preeclampsia and 34 pregnant women with pregnancy-induced hypertension and 50 pregnant women with normal pregnancy evolution as control group. We have performed hematological and biochemical tests, using serum samples from all analyzed patients and measured the serum concentrations of sFlt-1 and PlGF angiogenic factors. We found a significant correlation between the value of the arterial blood pressure, the proteinuria, the serum creatinine and the AST, on one hand, and the sFlt-1/PlGF ratio, on the other hand. The ROC curve has emphasized the fact that the proteinuria (AUC = 0.849), the AST (AUC = 0.664), the value of the arterial blood pressure SBP/DBP (AUC = 0.683/0.631), the serum creatinine (AUC = 0.674) and the sFlt-1/PlGF ratio, at a cut off value = 200, are effective preeclampsia predictors. Similarly, statistically significant increase (p = 0.001) of the sFlt-1 serum concentration in case of the pregnant women from the PE group (14365�6464 pg/mL) and from the PIH group (9892�8443 pg/mL), compared to the control group (3278�1444 pg/mL) and, respectively, a significant decrease (p = 0.003) of the PlGF pro-angiogenic marker for the group of pregnant women suffering from preeclampsia (119.30�56.63 pg/mL) and from PIH (129.12�21.41 pg/mL), compared to the control group (327.57�59.62 pg/mL). The results obtained within this research show that sFlt-1/PlGF ratio represents an effective preeclampsia predictor, confirming the fact that the study of the angiogenic factors may help to analyze the stratification of the risk degree in HTN pregnant women.


The authors, using stereocraniobasiometr of an own design, on 248 objects have established, that the point of crossing of the top edge of a pyramid of the temporal bon by the radix of the nervus Trigeminus occupies mainly back, lateral and high situation at brahicephalia and brachibasilia, and forward, medial and low situation at dolichocephalia and dolichobasilia. There is a corresponding of high, back and lateral situation of the given point and of small absolute sizes of a skull, and its low, forward and medial situation and of the large absolute sizes of a skull. The greatest degree of correlation takes place with an index of a triangle with tops in forward points of foramen acusticus externus and in glabella. The received data can be used at study of laws morfogenesis of a skull of the man, and at planning operations of transcutaneus radicotomia.


With the rapid development of AC/DC hybrid microgrids and the widespread use of distributed power resources, planning strategies for microgrids with high-density distributed power generation have become an urgent problem. Because current research on microgrid planning has not considered line factors, this paper analyses the planning of an AC/DC hybrid microgrid based on an AC microgrid. The capacity and siting of the distributed power resources are optimized, taking into account the influence of the line investment cost and the interactive power upper limit on the planning results. In the proposed model, the objective is aimed at minimizing the sum of investment cost, load-loss economic cost, and system losses, taking into consideration power balance constraints and feeder number constraints. The commercial solver CPLEX is applied to attain the optimal distributed power capacity and site. The theoretical results are verified by an actual system.


The netting anlysis is immediately discarded or even not presented in the classical references on the mechanics of composite materials, such as the books by Tsai and Hahn [1], by Jones [2] and numerous others. It is almost never referred in the literature on composites. However, even before the advent of the so-called advanced composites, pressure vessels designed according to the netting theory have been developed, manufactured and used, and still are.

The article presents the main results of an exploratory qualitative research conducted in the city of Buenos Aires, Argentina. The objective of the research was to inquire about the perceptions that teachers, parents, mothers and students have of the factors that influence in the shaping of the educational paths that deviate from the theoretical school trajectories. The purpose is to alienate certain thoughts of the school failure by exploring new interpretive possibilities. In this context, the analysis of the obtained information allowed to establish patterns of practice, attitudes and motivations for young people, families and institutions which are associated with favorable changes and
