Stress-relaxation measurements in uniaxial extension, in the terminal zone, were made of sulfonated ethylene-propylene terpolymer (EPDM), neutralized with zinc cation. The sulfonation levels were 15 to 20 meq/100 g polymer (0.47 and 0.62 mol %), and for each level the effect of the ionic plasticizer, zinc stearate, was investigated.. For all the polymers, the decay of the modulus with elapsed time was gradual and featureless, reflecting a broad distribution of relaxation times. Sensitivity of the ionomers' structures to thermal history before an experiment was suggested by irreproducibility in the magnitudes, but not the distribution, of relaxation times at a given temperature. For polymers containing zinc stearate measured at 80°C, the amount of permanent set was low for relaxation up to about 20 h, but increased rapidly with additional hours of stretch. Time-temperature superposition did not apply. Composite curves were constructed by matching the stressrelaxation response at short times; moduli measured at long times fell above the composite curve. The shapes of the composite curves were similar, regardless of the level of EPDM sulfonation or the presence of zinc stearate. The apparent Arrhenius activation energy for short-time relaxation at similar levels of the modulus was about 35 kcal/mol at 140°C for the unplasticized polymers and about 70 kcal/mol at 90°C for the polymers containing zinc stearate, in contrast to the usual effect of plasticizer on the rate of relaxation of amorphous polymers except near the glass transition temperature.


Opportunistic scheduling ooers a uniform perspective on predictive and reactive scheduling as iterative problem solving processes. In the context of reactive scheduling, it constitutes a knowledge-directed alternative to more search intensive iterative approaches. By adopting a scheduling process that opportunistically focuses attention on the most critical subproblem and carefully selecting the focal point of the next problem solving eeort, one can signiicantly constrain search while continuing to give attention to important scheduling objectives. Thus, one can maintain high-quality solutions in the face of changing constraints under stringent response time constraints. Control heuristics implemented in an architecture for opportunistic control determines the identiication, analysis, and prioritization of subproblems, as well as the formulation of problem solving tasks. The nature of the control architecture determines the the span of control heuristics that may be accommodated. In addition to the repertoire and nature of methods for subproblem resolution, the nature of control heuristics plays a critical role in the performance of opportunistic scheduling systems. This paper describes a novel control architecture which represents a generalization of earlier architectures for opportunistic scheduling. It accommodates what we have denoted as focal point-opportunistic scheduling strategies. New control heuristics that draw upon the extended ex-pressiveness of the novel control architecture are presented, as well as results from a comparative, empirical investigation of these heuristics based on reactive scenarios for a rich factory model. The experimental work reported here constitutes the core of this author's PhD dis-sertation work (thesis yet to be submitted) at the


Fiber‐optic sensors that are imbedded within composite materials could provide structural information during the life of the component, thereby avoiding many of the mechanical failures that today result in death, injury, or environmental accidents. Eventually this fiber‐optic smart structure technology could lead to radical new thinking in terms of engineering and structural integrity monitoring. An overview of this progress will be given, which will include the development and characterization of a number of fiber‐optic strain sensors including a fiber‐optic strain rosette for mapping two‐dimensional strain fields within composite materials, the detection of stress‐induced acoustic emission, and the development and testing of a multilayered fiber‐optic damage detection system fabricated within a full‐scale composite aircraft leading edge.


Fine-grained and ephemeral functions power many new applications that benefit from elastic scaling and pay-as-you-use billing model with minimal infrastructure management overhead. To achieve these properties, Function-as-a-Service (FaaS) platforms disaggregate compute and state and, consequently, introduce non-trivial costs due to data locality loss, complex control plane interactions, and expensive communication to access state. We revisit the foundations of FaaS and propose a new cloud abstraction, cloud process , that re-tains all the benefits of FaaS while significantly reducing the overheads that result from the disaggregation. We show how established operating system abstractions can be adapted to provide powerful granular computing on dynamically pro-visioned cloud resources while building our Process as a Service (PraaS) platform. PraaS improves current FaaS by offering data locality, fast invocations, and efficient communication. PraaS delivers invocations up to 32 times faster and reduces communication overhead by up to 99%.


Non-equilibrium two-parameter pumping transport through graphene ribbons, attached to reservoirs is described. A tight-binding model is solved using Keldysh formalism, and the crossover between adiabatic and non-adiabatic regimes is studied. Pumped dc currents through armchair ribbons show properties common in two-dimensional systems. The width-dependent dc current in zigzag ribbons, reveals that edge states akin to those in two-dimensional topological insulators, do not contribute to pumped transport in the adiabatic regime. The interplay between propagating and evanescent modes is discussed.


Pseudomonas aeruginosa a leading causative organism of nosocomial infections, periodically develop multidrug-resistance and causes increased mortality rate among hospitalized patients. This creates a major concern in the selection of appropriate antibiotics and periodic assessment of antibiotic resistant pattern is highly essential for efficient treatment of P. aeruginosa infections. Here, we attempted to understand the current scenario of antibiotic resistance of clinical isolates of P. aeruginosa. Twenty commonly used antibiotic were tested for antibiotic resistance/susceptibility among isolates. Virulence gene distributions in antibiotic sensitive and resistant isolates were studied by PCR. Here we report that recent clinical isolates of P. aeruginosa are developing resistance to commonly used antibiotics. Further molecular characterization of clinical isolates revealed that highly resistant strains hold lasA gene suggesting the importance of lasA towards antibiotic resistance.

This paper examines the imbalance between northern and southern civil society organisations (CSOs) in their engagement at international forums. It delves into some of the internal and external factors that inhibit southern CSOs from playing a bigger role in global governance discussions and in shaping the agenda of intergovernmental organisations. Finally, it makes some recommendations towards creating a "multipolar" civil society in line with the contemporary realities of a changing world order.


The preyield strain phenomena at room temperature and -195 deg C are examined in two ship steels, (an ABS class B semikilled steel and a rimming steel designated "project steel E"), as a function of annealing and normalizing temperature and the ferrite grain size. The yield points are measured by an approximately constant strain rate test, the load increasing continuously to the upper yield point. A step-load technique with SR-4 electrical resistance gages is used to determine the elastic limit and the preyield strain. These experiments are supplemented by microscopic observations on prepolished tensile specimens. While the stress levels for the initiation of microstrain, creep, and gross yielding are all predominantly chemistry and grain size dependent, the strain rate in each range is primarily a function of the annealing or normalizing temperature employed.


The reason and practice of triple education system construction of the rural community medicine in the Jinhua Polytechnic were analyzed,based on the position requirements,training objectives,and puzzlement and countermeasures in the practice.The construction of the triple education system better broke through the sptio-temporal limits and the contradictions of learning and practicing in the 3-year education of community medical students,and laid a foundation for achieving the training objectives and standards.


Blood substrate and hormone concentrations were determined in 16 children with Reye syndrome prior to and following administration of hypertonic glucose. Baseline concentrations of lactate, pyruvate, alanine, glutamine, glutamate, proline, hydroxyproline, lysine, and aspartate were elevated (p < 0.01), whereas citrulline and arginine were low. All substrate concentrations were below or within the normal range following 36 hours of therapy except those of lactate, pyruvate, and aspartate. Urea nitrogen excretion was reduced (p < 0.05) on the second day of therapy. Plasma concentrations of insulin and growth hormone increased and glucagon decreased during the first day. Cortisol remained elevated throughout the study period.


The influence of the reflected waves at the bonding boundary on the resonance waveform and temperature characteristics was investigated using α -quartz (QZ). The double-layered resonator specimen was fabricated using 129.55°Y- and 0°Y-cut QZ substrates with the thickness ratio x = 0.520. The temperature characteristic of the 1st and 2nd resonance modes at the range from 100 °C to 300 °C was deviated from the calculated values estimated by the equations considering thickness ratio and electric flux density ratio proposed in the previous work. Considering the phase matching conditions, it was clarified that the reflected waves at the bonding boundary are in phase in the lower acoustic impedance substrate and out of phase in the other substrate for the 1st mode, so the temperature characteristics are mainly dominated by that of the lower acoustic impedance substrate. In contrast, these relationships are reversed for the 2nd mode.


ABSTRACT We report an ensemble approach applied to the radiation dose modeling for a hypothetical radiation emergency with a long-term release of radioactive materials into the atmosphere. The study is aimed at improving the emergency response system in Russia and focuses on quantifying the impact of meteorological uncertainties on modeling the atmospheric dispersion and transport. Four sets of options of meteorological conditions are used: (i) classic global weather forecast (zero member), (ii) ensemble global weather forecast with 21 members, (iii) global weather analysis, and (iv) real local weather measurements. The numerical experiments have been conducted for four dates during September–October 2019 using the SOCRAT code for source term evaluation, WRF-ARW model – for weather prediction, and NOSTRADAMUS code – for atmospheric dispersion modeling and dose calculations. The comparable results have been obtained for all performed numerical experiments. The paper presents the results for a hypothetical release on 17 October 2019, but all conclusions are valid for all investigated dates. The ensemble approach has demonstrated to increase significantly the reliability of radionuclide dispersion predictions for severe accident conditions.


The performance of an active frequency doubler used to generate a pump signal for a solid-state microwave amplification by stimulated emission of radiation (MASER) based on paramagnetic impurity ions in sapphire is reported. The frequency doubler has been characterised in terms of phase noise, power dependence and frequency stability (Allan variance) for an output frequency range between 20 and 40 GHz. With the measurement system referenced to a 10 MHz hydrogen MASER, the doubler exhibits a single sideband phase noise of ∼−108 dBc/Hz at 1 Hz offset frequency, from which an upper limit fractional frequency instability of about 2 × 10−16 at 1 s integration time is estimated.


The aim of this paper is to clarify characteristics of building complex in the center district of Tokyo in terms of spatial compositions of urban open spaces. Initially, combinations of buildings based on scale, which is defined as total floor area and proportion of a building, are analyzed. Secondly, arrangements of buildings are analyzed, and thirdly the surroundings and the site shapes are analyzed. Finally, 8 spatial types based on 4 fundamental groups, which corresponds to the floor area ratio, are clarified through the above-mentioned characteristics. They represent one aspect of urban open spaces with dispersed buildings in the contemporary Japanese city.


The impact of materials is undoubtedly the object of research, due to the dynamic condition inherent in the bodies that interact in our universe. This work places special emphasis on the method of plate bending, which, due to its geometric configuration, interprets real impact situations to which some bodies are subjected, in addition to the low energy technique in which the energy available in the impactor is less than that absorbed in the breaking process, makes it possible to obtain information on the material in the elastic, plastic, initiation and crack propagation range. For research, the contribution of technological progress in instrumented test equipment by electronics is important, as it allows us to record much more information on the evolution of the contact between the impactor and the sample step by step. This information must be further processed and this phase of the research requires programming, modelling and simulation of the test dynamics to interpret or even predict the different phenomena that converge in the fraction of time in which the impact occurs. In this sense, our objective has been to study the physical behavior of different thermoplastic materials and their response to impact requests and to develop a series of models that try to simulate the phenome2632 Milton F.

So that more knowledge can be obtained in this field.


Attempts were made to isolate a virus from systemic lupus erythematosus patients, using lymphocyte cultures prepared from peripheral blood. Both cocultivation with VERO cells and fusion experiments in which lysolecithin and Concanavalin A were employed as fusing agents failed to reveal any presence of virus. Con A proved to be useful for heterokaryon formation in primate cells, fusion levels varying from 14-21% as shown by autoradiography.


We are interested in the discretization of the heat equation with a diffusion coefficient depending on the space and time variables. The discretization relies on a spectral element method with respect to the space variables and Euler's implicit scheme with respect to the time variable. A detailed numerical analysis leads to optimal a priori error estimates.


Fish-scale pit is one of the soil and water control measures in the slope,and it is also a kind of slope afforestation site preparation methods.Due to its simple construction,storing surface runoff,the effect of maintaining soil and water,and promoting the growth of trees is relatively remarkable,it is widely application.In order to study soil moisture of fish-scale pits of different specifications by using fixed-point monitoring methods,soil moisture of fish-scale pits of four specifications in the Loess Plateau region of Northern Shaanxi Province was studied.Results showed that different specifications had a significant impact on soil moisture content.In terms of soil water on semi-sunny steep slope and extremely steep slope,specifications may be ranked in the descendant order of middle,large,small,smaller and contrast,in terms of soil water on semi-shady gentle slope and shady gentle slope,in the descendant order of large,middle,small,smaller and contrast.


The problem of minimising ∫t0∞(x′Qx + u′Ru)dt for a completely controllable linear system, subject to the constraint |u˙|< 1, is shown to be equivalent to a singular optimal-control problem; the known singular theory is then used to obtain the optimal control.


We extend earlier investigations of heavy-light pseudoscalar mesons to the vector case, using a simple model in the context of the Dyson-Schwinger-Bethe-Salpeter approach. We investigate the effects of a dressed-quark-gluon vertex in a systematic fashion and illustrate and attempt to quantify corrections beyond the phenomenologically very useful and successful rainbow-ladder truncation. In particular we investigate dressed quark photon vertex in such a setup and make a prediction for the experimentally as yet unknown mass of the B_c*, which we obtain at 6.334 GeV well in line with predictions from other approaches.

Bisphosponates have been successfully used in the prevention of cancer related bone metastasis. Ongoing pharmacological modifications have increased their bone sealing potential. A few years after introduction of the latest bisphosphonate generation (pamidronate, zoledronic acid) first reports of jaw osteomyelitis and necrosis after tooth extraction appeared if patients had received bisphosphonates. This study reports on surgical experience with this new kind of therapy-induced jaw osteomyelitis and gives prophylactic recommendations.


Concrete-filled steel columns consist of circular, square or rectangular hollow sections filled concrete. Much research has studied for the behavior of concrete-filled steel structures. The advantages from structural point of view are the triaxial confinement of the concrete within the section, and the fire resistance of the column which largely depends on the residual capacity of the concrete core. The axial capacity of a concrete-filled rectangular or circular section is enhanced by the confining effect of the steel section on the concrete which depends in the magnitude on the shape of the section and the length of the column. Buckling tends to reduce the benefit of confinement on the squash load as the column slenderness increases. In circular sections it is possible to develop the cylinder strength of the concrete. When compare with reinforced concrete columns, the concrete-filled composite column possesses much better strength and ductility in shear and generally in flexure also. Many researches are being conducted about concrete filled steel column to get these advantages in building design. In this paper it is provided to the basic experimental study of compression behavior of the circular and rectangular tubular steel pipe filled with concrete.


In this paper, we divide the cooperation in multiple agent systems into task-based cooperation and information-based cooperation. We describe information-based cooperation as information synthesizing and decision making. To implement information synthesizing, agents' beliefs are decomposed into two levels. The higher level represents the possible information, and the lower level subsequently estimates a number function for the belief by synthesizing the possible information..

Low-density wood can be mechanically densified to produce value-added wood products. It is vital to have an understanding of the pressing parameters in order to fully utilize low-density wood and optimize its mechanical properties. Three pressing parameters (compression ratio, press temperature, and press closing time) were evaluated, and their effects on surface hardness, modulus of elasticity (MOE), and nail withdrawal resistance were determined. The purposes of this present study are to enhance the surface properties of aspen (Populus tremuloides Michx.) by mechanical densification and to optimize the densification process. Plainsawn specimens were prepared and mechanically densified on one face only using a softening-pressing-cooling technique. It was found that among the three chosen parameters, compression ratio was the most significant factor in influencing surface hardness, MOE, and nail withdrawal resistance. The effect of press temperature was not significant in most of the responses in this study. The optimum pressing conditions were found to be: compression ratio = 24.0 percent, temperature = 145 °C, and closing time = 7 minutes. After verifying the optimum pressing conditions, the hardness, MOE, and nail withdrawal resistance of surface densified aspen was improved by an average of 140, 23, and 132 percent, respectively. The hardness of surface densified aspen was almost equal to that of uncompressed red maple tested in this study. The surface densified specimens exhibited a glossy and smooth surface, suggesting that no surface coating would be required in end use.

Introduction: Perfusion in the body provides valuable information about physiological status and disease progression. Measuring perfusion in tumors is considered important with the recognition of angiogenesis, the process of developing new blood vessels, as a key element in the pathophysiology of tumor growth and metastasis. Many studies have used Gd contrast agents to evaluate tumor blood flow and vasculature but quantification has been complicated and model/agent dependent. Arterial spin labeling (ASL) is a noninvasive and quantitative technique that measures perfusion by magnetically labeling water as a freely diffusible endogenous tracer. Application of ASL to measure perfusion in tumor is a challenge due to the low perfusion values and artifacts caused by movement, susceptibility difference and fat in the abdomen, where tumors in experimental models are typically transplanted. Previously, we successfully demonstrated and quantified mouse renal perfusion using ASL. To optimize the sensitivity of ASL and determine the quantification error of low flow region, lumbar muscle was studied as a reference region for low blood flow. Subsequently, we applied the optimized protocol for perfusion measurements in an oncology model. Methods: All animal studies were approved by the local Institutional Animal Care and Use Committee (BMSI, A*STAR, Singapore). Sequence Optimization in muscle: Experimental optimization of scan parameters in muscle was carried out in C57BL/6 mice (n=5). To determine the sensitivity, flow values under various data averaging up to 100 ASL pairs were calculated in muscle. Although typically single TI is used to quantify flow with minimal scan time, the quantification accuracy has not been verified. We compared the quantification error using single TI versus multiple TI, with matched total scan time. The mean flow of 80, 90 and 100 averaging was regarded as the actual flow value for calculating the quantification error in each animal. The relationship between the quantification error and the SNR of the control image was determined from 2 regions of interest (ROIs) from 5 animals. Measurement of flow in tumor: For tumor studies, female BALB/cOlaHsd-Foxn1nu mice were intradermally inoculated with 1.25 million renal carcinoma cells (of A498 cell line) in 50% matrigel. MRI was carried out using the optimized sequence on 70 to 74 days after inoculation while anaesthetized with 1-2% isoflurane. Imaging and Analysis: Flow-sensitive Alternating Inversion Recovery (FAIR) ASL was implemented on a Bruker ClinScan 7T using single-shot spin-echo EPI. To improve sensitivity of ASL, a 10 mm receive surface coil was placed close to the region of interest. The FAIR method was carried out without global pre-saturation and using an optimized short TR of 6s and a minimal TE of 18 ms. Dummy scans were used to ensure that the signal was at steady state. Water excitation and 3D shim were used to minimize artifacts. An axial slice of 2 mm thickness crossing the lumbar muscle or the center of the tumor were acquired with in-plane resolution of 0.44 x 0.44 mm. TIs were varied from 0.2 s to 4 s to allow more accurate quantification. T1 measurement was performed with inversion recovery SE-EPI with TI changing from 0.2 s to 8 s. Using Matlab, the perfusion was calculated based on the pair-wise subtracted FAIR images and the T1 map. Results


Accountability of the elected leaders is one of the key factors in a representative democracy. Bangladesh restored a democratic ruling system in 1991 but has struggled to create an effective institutional mechanism to hold the political leaders before the citizens. Information has often been called the oxygen of democracy because of its power to bring accountability through transparency and public disclosure. With the boom of news media organisations and the emergence of the movement for the right to and freedom of information in the early 2000s, many argued that information institutions could build the mechanism for political accountability. On that background, Bangladesh enacted the Right to Information Act in 2009 and established a few key public information institutions including the Information Commission (IC) and Access to Information Programme hoping that the freedom of information would not only challenge the culture of secrecy and veil but also encourage the elected leaders to be answerable to the citizens. But did it really happen? Why? I looked for the answers in this study though the conceptual and analytical lens of freedom of information, proactive disclosure and accountability. For this study, I mainly used the data and cases gathered from secondary sources namely policy papers, reports, newspapers, journals, books and online spaces. I also utilised my own experience of working with a few state organisations. I analysed the current status of accountability mechanisms in Bangladesh focusing mainly on the political accountability (often called the vertical accountability). I also examined a few recent cases in order to understand the role of the information institutions in bringing the political accountability in the current fragile democracy in Bangladesh. Considering the poor democratic practices in the recent years, findings of this study suggest that the accountability of the political leaders has increased to a certain considerable extent. I argue that this is partly because of the increased transparency and proactive disclosure in the formal and informal institutional mechanisms, and mostly because of the leading active role of the mass media organisations. I conclude with the argument that despite having this increased transparency and freedom of information, this improved accountability is not sustainable without an effective democratic institutional mechanism.


We have investigated structural changes of amorphous borosilicon carbonitride materials with atomic ratios of B/Si/C of 2/3/6 and 4/3/6 calcined at several temperatures. The boron K -edge x-ray absorption spectra showed that the structures of both hexagonal boron nitride ([BN_3] unit) with nitrogen-void defects ([BN_2] and [BN_1] units) and boron oxide existed in the samples, and the relative peak intensity due to the [BN_3] unit became stronger by increasing the calcined temperature. It is thought that the well-developed B–N chain and the borosilicate glass coating lead to the high resistance to oxidation at high temperature. X-ray diffraction and infrared measurements followed the x-ray absorption near-edge spectroscopy findings.


The Texas Christian University (TCU) Computer Science Department was established in 1981. From the outset, the Department's CS1 course has presented significant teaching challenges due to the wide diversity of student's taking the class. Traditionally, only 25-35% of the students enrolled in the course are computing science majors, the remaining being students from a wide diversity of disciplines, many of which are non-science based. Despite the diversity, it has been necessary for the course, and its content, to be structured to satisfy essential core requirements for students majoring in computer science and computer information science as well as to meet program requirements for the many non-computer science majors taking the course. This paper discusses some of the unique issues associated with teaching a Java-based CS1 course to a very diverse group of students, the majority of which have very unsophisticated problem solving skills, and little or no programming expertise. A representative set of experiments and programming assignments are included.


The article «?Puede la razonabilidad ser un criterio de correccion moral?» by Ernesto Garzon Valdes, analyzes the limits to the contents of normative ethics, and focuses on the concept of reasonableness. Besides, Garzon proposes a «negative way» to determine moral contents on the basis of radically evil. This paper examines the problems the negative way does not remove as regarding questions of moral foundations, and points out the aims of Garzon's article in the context of contemporary debates on moral and political philosophy.


An augmented Phillips-Heffron model for multi-machine power system with multi-TCSC installed is built up. Based on this model a practical example, i.e., in a 4-machine 11-bus testing system when two TCSC controllers are jointly operated the interaction of TCSC exists, is given. It is also pointed out that there is the possibility of existing negative interaction among multi-TCSC controllers located at a same area of a multi-machine power system, so this factor should be taken into account during the design of TCSC in order to ensure the coordinative operation of multi-FACTS controllers in a same power grid.

While Hector's dolphin (Cephalorhynchus hectorii) has been the topic of many research projects within the first Marine Mammal Sanctuary in New Zealand, few long-term analytical abundance and distribution projects in other population strongholds have been conducted. The primary purpose of this thesis project was to test quantitative observations that suggested that this unprotected population of Hector's dolphin at Te Waewae Bay, on the south coast of the South Island, New Zealand, may be in decline and utilises non-continuous portions of the coastline. Seasonal patterns of distribution and density were extracted from a rich data set collected over 24 consecutive months that provided fine-scale data of encounters with dolphins along four preplanned transects that followed the concave nature of the bay. Monthly data were binned into seasons producing eight seasons of data over the two years. Survey results revealed that Hector's dolphin in warmer seasons were found in greater densities closer to shore and that in the cooler seasons the range extended outward and across more offshore areas. Individual seasons did not have as strong a pattern as the complete two year data set that indicated hotspots of higher densities of dolphins in the vicinity of freshwater inputs into Te Waewae Bay. To explore individual spatio-temporal movement patterns and how the individual patterns relate to group spatio-temporal patterns, 58 individual Hector's dolphin movements were extracted from geo-tagged photographic data and then analysed. Visual analysis of movement patterns of individual dolphins were found to vary dramatically, having distribution patterns that exhibited a high degree of site fidelity. Most notable were the twenty one dolphins that remained in relatively small areas on either the east (ten dolphins) or west (eleven dolphins) halves of the bay. This evidence of strong site fidelity may suggest partitioning along as yet unidentified social or environmental parameters. Abundance estimates were calculated from mark-recapture photographic


In this paper, Painleve analysis is used to test the Painleve integrability
 of a forced variable-coefficient extended Korteveg-de Vries equation which
 can describe the weakly-non-linear long internal solitary waves in the fluid
 with continuous stratification on density. The obtained results show that
 the equation is integrable under certain conditions. By virtue of the
 truncated Painleve expansion, a pair of new exact solutions to the equation
 is obtained.

In the software industry, good design often translates into good user experiences. As accessibility is a key component of usable software, there are opportunities for software professionals to include accessibility in their skill set. However, despite a push to motivate more companies to include accessibility as a desired knowledge and skill set, little is known about how much companies are seeking to recruit employees with accessibility proficiency. In this paper, we investigated the extent to which companies seek software designer and developer skills in accessibility by analyzing software job posts on LinkedIn. Our results showed that the majority of job posts did not require any accessibility skills, and that educating developers and designers about accessibility was a required qualification for many of the accessibility-focused software jobs.


Choosing an effective subsidy mode is crucial for promoting the healthy development of the biofuel ethanol industry. After considering the differences in the social welfare effects of different subsidy models, we construct a Stackelberg game model to examine the chain of the fuel ethanol industry consisting of a downstream channel intermediary as the leader and an upstream production enterprise as the follower. We then discuss how the R&D subsidy mode and production subsidy mode affect social welfare, and what kind of subsidy mode should be adopted under different conditions. The study found that different subsidy modes affect corporate profits and consumer surplus by affecting the price and demand of fuel ethanol, which in turn affect the level of social welfare. In addition, the study found that both R&D subsidy mode and production subsidy model are not always efficient. The optimal subsidy mode depends mainly on the R&D difficulty coefficient and the slope of the inverse demand function.


The aim of the process is to improve flat connections, with a view to considerably reducing the contact resistance of the latter, which is generally high due to flaws in the surface flatness of the conducting ranges facing one another. The process consists in forming on a first conducting range (10) designed to enter into contact in a flat connection with a second conducting range, a surface state containing a plurality of studs (12) uniformly distributed, then in applying opposite each other and clamping together the two ranges so as to establish a contact between each stud and the second range. Applications: particularly interesting for high voltage connections and very high frequency and ultrahigh frequency ''strip line'' connections.


This paper presents the effects of rotation of polarimetric matrices on man-made structure classification by polarimetric synthetic aperture radar (POLSAR). Both coherence and covariance matrices are used for classification. Some important modification is also applied to the previously suggested rotation algorithm. The advantage of this modification is to guarantee that the cross-polarized component is surely minimized. As a result, we were able to distinguish man-made structures from other areas more effectively than the related methods.


Septic shock (Klebsiella pneumoniae infection) accompanied with chronic hypokalemia and postoperative hyperglycemia was induced by surgical and infectious stress in a 64-year-old female patient with a large parasagittal meningioma that compressed the hypothalamic area. We concluded that a dysfunction of the compressed hypothalamus had some relation to the grave prognosis after surgical removal of the tumor.

The paper is a partial output of the research project CREdu: gender equality in the environment of secondary vocational schools. Project is carried out by the NGO EsFem with support from Slovak Research and Development Agency under contract No. APVV-0726-07. The project focuses on the analysis of gender inequality in secondary vocational schools in Slovakia with aim to expand the knowledge base on this issue. Secondary vocational school may designate a future career. Gender-specific signals are carried through formal and informal curriculum and have an impact on aspirations and performances of female and male students. We assume that there is a relationship between the school system and gender patterns in the society. The school is a powerful element in the process of gender socialization of children and young people. It plays an important role in reproducing gender inequalities in society. This is done through the reproduction of gender stereotypes in teaching materials, environment and in behavior of she-teachers and he-teachers in schools. The lack of understanding of the gender related issues may cause overlooking of unequal position of women and men in the society. Actual inequalities are often hidden behind formal gender equality guaranteed by the constitution and laws. It is therefore necessary to raise awareness and reflect the asymmetry between men and women in society through scientific gender analysis. The authors analyze the key legislation and gender segregation in the secondary vocational schools in Slovakia with respect to the ongoing reform of education. The first part focuses on the content analysis of the current legislation, opportunities and threats for the gender equality. The first part consist of: the definition of basic legal norms and the structure of the education system in Slovakia; the identification of negative trends in education system; the main topics of the reform of vocational education and related issues; the position of women and men in secondary vocational schools in Slovakia. The second part of the paper focuses on the analysis of gender inequality in Secondary Vocational Schools in Slovakia. Inequality is manifested both in the representation of men and women in pedagogical staff and executive positions, and also on the he-students and she-students level. The second section thus includes analysis of gender inequality in secondary vocational schools (description of environment, categories of schools, management positions, and cluster analysis of secondary vocational schools). Analysis of the Secondary Vocational Schools environment was carried out by gender audit in which statistical information from the Institute of Information and Education Prognoses as well as from the Secondary Vocational Schools websites were the principal sources of data. The gender blindness of the recent reform of vocational education is the most serious finding of content analysis of the current legislation. The data obtained from gender audit show that gender inequality is the reality in the Slovak secondary vocational school system. It is manifested in higher representation of women in school system, but at the same time in higher number of men in principal positions. The differences are significant in numbers of she-students and he-students in particular fields of study. Also, in terms of he-teachers and she-teachers similar differences, although to a lesser extent, are present among the fields of study. Overall, it can be concluded that in the Slovak secondary vocational school system there exists both vertical (the representation in positions) and horizontal (studying and teaching in particular fields of study) segregation, which may be the cause of unequal opportunities for men and women to be able to be applied at the job market.


Gene transfer into peripheral blood lymphocytes has several potential applications including the correction of genetic diseases and therapeutic approaches for HIV-1 infection and cancer. Integrating gene transfer system based on murine oncoretroviruses are a convenient tool for such strategies. However, the recent occurrence of uncontrolled clonal T cell expansions in two patients treated with retroviral gene transfer for X-linked severe combined immune deficiency has raised the concern of the risk of insertional oncogenesis associated with the clinical use of integrating viral systems. In vitro studies have indicated that murine viral vectors tend to integrate in the vicinity of transcription start regions of the genome, thus providing a possible mechanism for oncogene activation, however, data from clinical gene transfer trials is lacking.

We are following patients affected with adenosine deaminase (ADA) deficiency who have received T-lymphocyte-directed, retroviral-mediated gene transfer starting in 1990. The first treated patient received the last infusion of gene-corrected cells 12 years ago, has never shown any sign of lymphoproliferation and still carries ~20% of gene-corrected peripheral blood lymphocytes. We set out to study the integration sites in the cells of this patient with the aim of mapping the regions involved by retroviral integrations, determining their localization with respect to known genes, and assessing whether a preferred pattern could be defined. Genomic DNA was prepared from stored lymphocyte samples dating 1991, 1992, 1995, 1998, 2000, and 2003. By inverse PCR and ligation-mediated PCR, we have identified ~860 bona fide insertion sites. Search for homology within the human genome using BLAT returned ~330 unique hits that involved a variety of genes, including transcription factors and oncogenes (e.g. RUNX1, STAT5, FYN). To evaluate the distribution pattern of these integration sites, 2000 randomly generated data sets of genomic coordinates were assembled and their distribution relative to annotations of the human genome was analyzed. A preliminary comparison of the random distribution to our experimental samples showed that retroviral integrations in cells obtained from the patient were significantly skewed toward regions within 2 kb of genes (p<0.002) and CpG islands (p<0.001).

These results suggest that, similar to what observed in murine fibroblast and human cancer cell lines, transcriptionally active regions of the genome may be preferred targets of retroviral vectors in human primary T lymphocytes. At the same time, our observations show that the resulting integration events are compatible with long-term, event-free in vivo survival of gene-modified cells in clinical settings.


The following study explores the antimicrobial activity, synergistic effect, potentiation effect and phytochemical analysis of different extracts of C.buchanani leaves. C.buchanani leaves were dried and extracted by soxhlet extraction using four different solvents viz Ethyl acetate, Methanol, Acetone and Ethanol. The extracts of C.buchanani leaves were screened against Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Klebsiella pneumoniae, Proteus vulgaris, Xanthomonas citri, Citrobacter divergence, Vibrio cholerae, Candida albicans & Aspergillus niger. The antimicrobial activity indicated that ethyl acetate extract gave maximum inhibition followed by methanol, acetone and ethanol. Proteus vulgaris was found to be most susceptible while Aspergillus niger was resistant to all the organic extracts for antimicrobial and synergistic activity. The combinations of ethyl acetate extracts has shown highest synergistic effect against P.vulgaris. Antagonistic effect was seen for fungal pathogens. Potentiation effect of Gentamicin was seen in ethyl acetate extract against P.vulgaris. The phytochemical constituents varied significantly depending upon the type of solvent used. Saponins and alkaloids were present in all extracts. Thus, C.buchanani is highly rich in the diversity of phytochemical constituents.


This study describes the nesting behavior of Rose-ringed Parakeets (Psittacula krameri) in Southern Punjab, Pakistan. Rose-ringed Parakeets are native to Indian sub-continent, where they are considered to be one of the most significant agricultural and horticultural pests of fruits and grains. Altogether 50 trees of 6 species belonging to 6 genera and 4 families were recorded which were used to make nests. Block randomized method and systemic observation were preferred to collect data through check lists. Cross-sectional survey research design was employed to conduct the study. Results indicate tree species preferred by parakeets are Dalbergia sissoo (Sheesham), Acacia nilotica (Kikar), Ficus religiosa (Pipal), Mangifera indica (Mango), Syzygium cumini (Jaman) and Albizia lebbeck (Black Siris) to make nests. The ratio of nest formation found more on Dalbergia sissoo and Acacia nilotica than the other tree species. Diameter at Breast Height (DBH) of the tree was found suitable for nesting ranged from 21.983 to 85.98 inches. Height of the roost was observed from 85.318 to 284.318 inches on tree from ground level. Rose-ringed Parakeet likes 2.285 to 8.04 inches wide roost hole and clutch size was 1-2 eggs per roost. It was concluded from the current study that population of this avian pest might be increasing due to availability of favorable conditions for its nesting behavior.

 . This study tested the hypothesis that blockade of IL-17 signaling would inhibit activation of cNKs to improve blood pressure and fetal growth in RUPP rats. On gestation day (GD) 14, osmotic pumps infusing IL-17 RC (100 pg/d), a soluble receptor for IL-17, were implanted into pregnant rats undergoing RUPP (RUPP+IL17 RC). On GD 19, circulating and placental T

 H
 17 populations (% gated) were significantly increased in RUPP (23.1±3.9%, n=9) compared to NP (8.5±3.9%, n=9) rats and were suppressed in RUPP+IL17 RC (8.3±3.1%, n=9). Circulating T
 H
 17s followed the same trend. Placental cNKs, significantly increased from 7.2±2.8% in NP to 16.6±3.3% in RUPP, and were normalized to 7.2±2.8% after IL-17 blockade (p<0.05 vs RUPP). Placental cNK proteins and circulating cNKs showed a similar trend. Placental levels of the cNK cytokine, TNFα, increased from 28.5±.01 pg/mg in NP to 46.2±6.0 pg/mg in RUPP and was normalized to 28.5±4.6 pg/mg in RUPP+IL-17 RC (p<0.05 vs RUPP). Placental MIP3a, a cNK chemokine, had a similar trend. Assessment of
 in vitro
 cytotoxic activity of placental NK cells from rats in each group demonstrated a 5-fold increase in cytotoxicity by RUPP NK cells compared to NP NK cells. This was blunted in NK cells from RUPP+IL17 RC rats. Placental ROS was increased in RUPP compared to NP and significantly decreased with IL-17 blockade. Fetal weight decreased from 2.4±0.04 g in NP to 2.1±0.04 g in RUPP and increased to 2.3±0.05 g in RUPP+IL17 RC (p<0.05 vs RUPP). Placental weights followed a similar trend. MAP increased from 93 mmHg in NP to 120 mmHg in RUPP, and was decreased to 105 mmHg in RUPP+IL17 RC (p<0.05 vs RUPP). These data demonstrate a direct role for IL-17 signaling to mediate NK cytotoxic activation in response to placental ischemia during pregnancy.


Ion exchange of the layered compound K4Nb6O17·3H2O with mono- and bi-valent cations (Li+, Na+, Ca2+, and Ni2+) has been carried out in the aqueous chloride solutions at 90 °C. Only Na+ was found to attain to complete exchange. For exchange with Li+, almost all the K+ ions in the interlayers seemed to be replaced, although partial decomposition was observed. The degrees of exchange with the bivalent cations were found to be < 50%. The interlayer spacings of interlayers I (hydrated) and II (not hydrated) in K4Nb6O17·nH2O and derivatives were determined from electrondensity projections along the b axes. From the change in interlayer spacings, it is considered that K+ ions in interlayer II are only substituted by monovalent cations whereas both mono- and bi-valent cations exchange for K+ in interlayer I. By exchanging K+ in interlayer II with Li+ or Na+, this interlayer becomes hydrated.


Nitrogen dioxide (NO2) is one of the six gaseous air pollutants that need regular monitoring in big cities around the world. It contributes to particle pollution and can trigger chemical reactions that lead to increased concentration of ozone in the troposphere. Lahore, a metropolitan city of Pakistan is among the most polluted cities in the world. Area-wide monitoring of NO2 is necessary in this region to devise a long-term emission control policy. However, it lacks a dense network of ground-based air quality monitoring stations (AQMS), which is need of the hour. The installation of AQMS requires huge financial resources. In this paper, we investigate a machine learning-based approach to estimate surface level concentration of NO2 using remote sensing and modeled meteorological data. We use multiple linear regression (M1) and a polynomial fitted regression (M2) techniques to model ambient NO2, using remotely sensed vertical column density (VCD) of NO2, acquired by tropospheric monitoring instrument (TROPOMI), onboard Sentinel 5P satellite, and modeled meteorological parameters such as surface pressure, dew point temperature, and wind speed. Results show that M2 outperformed M1 with an $\mathbf{R}^{2}$ value of 0.49 and root mean square error (RMSE) value of $\mathbf{19}.\mathbf{27}\ \mu \mathbf{g}/\mathbf{m}^{3}$. There is a moderate positive correlation between in-situ measurements and remotely sensed VCD of NO2, which makes it an interesting problem that needs to be explored further to achieve desirable results.


COUNTRY'S external liquidity consists of such resources as are readily available to its monetary authorities for the purpose of financing deficits in its balance of payments and defending the stability of its rate of exchange. These resources may take the form of liquid assets, such as gold and foreign exchange, or of facilities for borrowing such assets from abroad. The first part of this paper sets forth criteria for determining, in principle, the most desirable aggregate amount, composition, and, to a lesser extent, country distribution of external liquidity in the world. The second part deals with the instrumentalities that are, or might conceivably be, used to attain or approach these optima. Much that has been written in the postwar period about the adequacy of world reserves or world liquidity would appear to rest on uncertain logical foundations. One frequent approach is to estimate a figure for required or optimal reserves, by starting from some past date when total reserves are supposed to have been roughly satisfactory and adjusting this total for the growth in the value of world trade between the base date and the present time. While the value of world trade is, admittedly, a relevant consideration, there are many other dynamic factors affecting the need for reserves. This is emphasized in many of the writings in which such historical comparisons appear.' It is not surprising, therefore, that calculations starting from different base dates, at each of which reserves may have been roughly satisfactory, yield enormously different results. Moreover, if it is possible to say that reserves were or were not adequate at the base date, one wonders if it is not possible to apply the same criteria


Over the past short time, network security facing a lot of challenges. Confidentiality, integrity, and availability are the major concerns of the data. To cope with this problem different systems have been developed and the systems are known as Intrusion detection systems. Intrusion detection system detects the violation of confidentiality, integrity, and availability of the data. Intrusion detection systems are developed on the bases of two different detection techniques, signature-based technique and anomaly-based technique. Classification approach has been widely adopted for the development of the anomaly detection model to classify the data into normal class and attack class. But irrelevant and redundant features are the obstacle for classification algorithm to build an efficient detection model. This paper proposes a detection model, ant system with support vector machine, which uses ant system, a variation of ant colony optimization, to filter out the redundant and irrelevant features for support vector machine classification algorithm. KDD99, which is a benchmark dataset used for anomaly detection, has been adopted here. Each instance in KDD99 has been represented by 41 features which also has some redundant or irrelevant features. Ant system has been used to remove those redundant and irrelevant features. The selected feature subset using ant system is then validated using support vector machine. The experimental results showed that the performance of the classification algorithm, when trained with the reduced feature set, has been improved. The performance measures used in this comparison are true positive rate, false positive rate, and precision.


In the aftermath of the 11 September 2001 terrorist attacks, the American flag became ubiquitous—in stores, on cars, at work, in neighborhoods, in churches, and on t-shirts and other assorted articles of clothing. Over a year later, the Stars and Sfripes continue to be in vogue, to say the least. Countless billboards and bumper stickers, often with the flag as a backdrop, declare the United States to be "One Na tion, Under God." Meanwhile, the stirring refrain of the patriotic invo cation "God Bless America" echoes in the collective national consciousness, whether it be sung by members of Congress on the steps of the Capitol, played by marching bands during football halftime shows, or proclaimed by ministers in churches across the nation. Civil religion, it seems, is back, and with it comes a number of familiar, but troubling, questions. Having noted this, however, it should be observed that American civil religion has never really gone away. As a cultural phenomenon, civil religion has been around since at least the revolutionary era, soci ologist Robert Bellah observed in his seminal 1967 essay, "Civil Relig ion in America." "What we have," Bellah writes, "from the earliest years of the republic is a collection of beliefs, symbols, and rituals with respect to sacred things and institutionalized in a collectivity." This religious understanding of the new nation, Bellah continues, "while not antithetical to, and indeed sharing much in common with, Christianity, was neither sectarian or in any specific sense Christian."1 It was, how ever, distinctively American. Since Bellah first raised the issue, count


One of the most important goals of the HELIOS-1 and -2 missions is the investigation of discontinuities with strong variations in the magnetic-field magnitude as, for example, shock waves. Observational studies of such events with high time resolution at low telemetry rates require an on-board automatic identification system and a big core memory. For this purpose a quality index is calculated on board using both a long and short time average of the magnetic-field data. By this quality index the memory read in is triggered. The principle of operation and the technical layout is discussed.


ABSTRACT Introduction: Glycogen storage disorders (GSDs) are mainly caused by over-accumulation of normal or malconstructed glycogen. A few GSDs, Adult Polyglucosan Body Disease (APBD), Andersen Disease, Tarui Disease and Lafora Disease are also associated with pathogenic inclusion bodies called polyglucosan bodies (PB) consisting of malconstructed glycogen (polyglucosan) in complex with several enzymes of glycogen metabolism. A treatment for GSDs is urgently required. This review examines the pharmacological avenue for curing PB-involving GSDs. Areas covered: I describe here the pros and cons of the structure-based drug development approach. This functional module-based approach can generate efficacious drugs, but with a large pleiotropic potential. Solutions based on modulations of affinity and specificity of putative drugs and on multi-targeting are then described. Next I discuss the targets of GSD pharmacological therapy: glycogen synthase (GYS), glycogen metabolizing enzymes and inclusion bodies. Finally, image-based high-throughput screening (HTS) is described as a methodological platform for PB-involving GSD drug discovery. Expert opinion: The conclusion of this review is that the pharmacological approach should be the leading therapeutic strategy for curing PB-involving GSDs. This approach enables broad characterization of underlying causes of PB-involving GSDs, an exhaustive examination of multiple mechanistic strategies for therapy and fast translational potential.


In determining the application efficiency the capability of inter-node connectivity among nodes is essential. Some nodes are also involved to uphold the flow of information from the sensor to remote users. A node loss can be encountered due to deployment ruthless and unattended areas. The network may get partition into multiple disjoint blocks and stop functioning because of depletion of onboard energy or due to physical damage. In this paper, the current and up to date state of research on the dynamic node relocation in Wireless Sensor Networks is presented. This work categorizes the node relocation techniques in to post-deployment and on-demand relocation depending whether the optimization is performed at the time of deployment or when the network is operational. This paper also identifies the open problems and future directions in this area of research.


We study a Heisenberg S=1/2 ring-exchange antiferromagnet which exhibits a quantum phase transition from a spontaneously dimerized (valence bond solid) phase to a magnetically ordered (Neel) phase. We argue that the quantum transition is of unconventional nature; both singlet and triplet modes of high density condense as the transition is approached from the dimer side, signaling restoration of lattice symmetry. These features are consistent with "deconfined quantum criticality", of which the present model is believed to be the only example so far.


A lateral interface connecting two regions with different strengths of the Bychkov-Rashba spinorbit interaction can be used as a spin polarizer of electrons in two dimensional semiconductor heterostructures [Khodas et al., Phys. Rev. Lett. 92, 086602 (2004)]. In this paper we consider the case when one of the two regions is ballistic, while the other one is diffusive. We generalize the technique developed for the solution of the problem of the diffuse emission to the case of the spindependent scattering at the interface and determine the distribution of electrons emitted from the diffusive region. It is shown that the diffuse emission is an effective way to get electrons propagating at small angles to the interface that are most appropriate for the spin filtration and a subsequent spin manipulation. Finally, a scheme is proposed of a spin filter device, see Fig. 9, that creates two almost fully spin-polarized beams of electrons. PACS numbers: 72.25.Dc, 72.25.-b, 72.10.Bg, 73.63.-b


The aim of this paper is to present concepts and algorithms for formation navigation in multi-mobile robots systems. The behavior based approach was chosen considering a correspondence with biological systems. The paper presents aspects concerning absolute and relative mobile robots positioning within a formation, as well as inter-robot communication using a client-server model and TCP/IP protocol. The simulations and real-world experiments with Pioneer mobile robots led to results backing up the theoretical part.


Abstract: Fluid viscous damper is the most commonly used tool for controlling structures' responses. Fluid viscous dampers with different construction technologies are applied in order decrease the responses of structures to the seismic vibrations. During the recent years, controlling structure has turned into a scientific technology to protect structures against wind and earthquake loads. In the present study linear dynamic and non-linear static analysis was adopted to assess the seismic performance of an irregular diaphragm building. Building with and without fluid viscous damper have been taken.The outcomes of the study will be beneficial to assess the performance of existing building vulnerable to seismic loads after the installation of fluid viscous dampers.


This chapter proves that the outlines of a Franciscan school system were taking shape from the 1220s onwards, particularly with regard to the organization of study houses where friars could receive their lectorate training, and with regard to the appointment of lectors in other friaries, provides continual education to the order's literate friars. From this vantage point, it makes sense to interpret the 1260 Narbonne constitutions as a confirmation, systematization and re-enforcement of already existing practices and regulations than as a breach with the past. After the first vocal approbation of the Franciscan movement in 1209 by Pope Innocent III, it witnessed a dramatic expansion, drawing many postulants from Italy's urban centers. After Francis's retreat, the order was led temporarily by the vicar general Peter Catani, who had been a learned lawyer prior to his entrance in the order.Keywords: Franciscan school system; lectorate training; Narbonne constitutions


This article describes the outdoor implementation of a decentralized consensus algorithm which drives multiple quadrotors to an autonomously decided consensus point. The quadrotors use a GPS module for localization and Xbee modules for data exchange in order to autonomously achieve consensus. A novel synchronized, time-slotted and scalable communication protocol is proposed, which avoids data packet collisions and ensures real-time connectivity between agents. This protocol can address changing communication graph topologies and temporary link breaks and additions. The performance of this protocol and its effect on consensus performance is characterized. The consensus and communication experiments are implemented on a testbed of six quadrotors in an outdoor environment. Details regarding the consensus experiment and communication protocol are presented.


Coronary slow flow phenomenon (CSFP) is characterized by delayed opacification of coronary vessels in a normal coronary angiogram. The incidence of CSFP is reportedly 1% among patients undergoing coronary angiography, and is more prevalent in patients presenting with acute coronary syndromes (ACS). Over 80% of patients with CSFP experience recurrent chest pain. A relationship between CSFP and ventricular arrhythmias has also been reported. Left bundle-branch block (LBBB) is a strong, independent predictor of heart failure, sudden cardiac death, cardiovascular death, and all-cause death. New onset LBBB has also been shown to be prognostic for patients with ACS, and should be considered in risk stratification to identify high-risk patients. We report intermittent LBBB associated with CSFP in a patient presenting with ACS. We propose that LBBB may be a result of coronary ischemia secondary to


This paper analyzes the impact of music file sharing on CD purchases. Traditionally , two arguments are opposed concerning the impact of the music file sharing on CD sales. On the one hand, MP3s downloads only reduces sales of legitimate. On the other hand, consumption of free MP3s could lead people to buy CD which they would never have bought otherwise (the "sampling effect"). Because the court in the Napster case and some academic researchers have dismissed this sampling effect, this article seeks to assess whether sampling does indeed occur and in the affirmative what are the relative contributions of the positive sampling and the negative competition effects of MP3 files on CD purchases. To do so, we administered an anonymous online survey in two French graduate schools from May 26 to June 3, 2004. Using answers to the questions, we analyze the factors that influence the probability to increase CD purchases after acquiring MP3 files and those that influence the probability to decrease CD consumption. First, our estimation results suggest that there exist two populations of music consumers: people who sample a lot (the explorers) and those who do not sample (the pirates). We show that MP3s consumption leads to an amplification of consumption patterns: music fans use MP3 files to discover new genres, artists and albums, which tends to increase their purchases of CDs, while students with little interest in music use Mp3 files as direct substitute to CDs. Secondly, we provide evidence that the channel of MP3 acquisition also matters: communities formed around an intranet positively impact CD consumption. JEL Classification: L82, L86


The utility model relates to a daily necessity. For a prior backpack, a zipper is arranged on the upper surface of the backpack. When a user is on a trip or in a crowded bus, articles in the backpack are easy to steal, which brings inconvenience to the user. The utility model provides a theftproof backpack which can prevent articles in the backpack from being stolen when a user is on a trip or in a crowded bus. The theftproof backpack which comprises an emulational zipper, invisible zippers and a backpack strap is characterized in that the emulational zipper is arranged on the upper surface of the backpack; and the invisible zippers are arranged at the bottom and the back of the backpack. When articles are taken out, the backpack strap arranged on the back is taken off, and the invisible zippers at the back and the bottom of the backpack are unzipped.


The literature of the children of forced disappeared victims, including that of Raquel Robles and Josefina Giglio, who went through the traumatic experience of the last Argentine civic-military ecclesial business dictatorship in 1976, has been the subject of multiple approaches by vernacular critics (Reati, Domínguez, Basile), or foreign (García Díaz, Bolte, Gatti, et al). In this study, I name the group as lowercase in order to displace the institutional character that, although important, can reduce the perspective that I am trying to display. This perspective focuses on questioning what the writing of children of the disappeared contributes in terms of complexity to literary studies within the framework of memory-literature articulation. Thus, I notice an accumulation of writings, whether in the multiple arc of narrative or poetry, where the assumption of the voice that enunciates, in some cases, works the experience in the first person from styles already registered in literature, although the experiences of the authors enhance writings that are difficult to place in literary trends. As if literature were to make visible the very tension that its politicity implies from the narrative voices with one foot in the lived experience and the other in the creative laboratory; It is also necessary to point out that this experience places state politics as the central node since it reconfigured the life not only of the authors but of all society, in this case Argentina. In the selected novels we are faced with what Jacques Rancière (2015, 2011) understands as a principle of action, from which neither literature nor readers can be far from a new ethos. From this it is possible to connect with certain experiences that emerge in this case from both novels and that affect our perception of reality and history. Argentine literature, born in the very bosom of the nation-state, is not the same after the sons once they intervened in the street in the second half of the 90s of the last century to demand justice, they speak in the new millennium and write experiences that affect us all, and that reshape the ways of thinking politics, literature and history.


This paper discusses a problem where jobs of random quality, or importance, arrive at random times and must be done by one of a fixed set of men on hand. The men can all complete any job in an exponential amount of time, with mean l/u, but the men are of different known qualities. Once a man finishes a job he again becomes available to do future jobs. If a man of quality p is assigned to do a job whose value is observed to be x, a reward rp,x is received. Also a cost of cp is incurred per unit time that a man of quality p is kept idle. The decision maker must observe the values of the incoming jobs and assign them to available men so as to maximize expected reward per unit time. The problem is set into the framework of a G/M/n queue with a possibly limited waiting room, and the optimization is done by techniques of Markov decision analysis.


In view of the bottom slab crack in side spans of a large span P.C.continuous box girder bridge occurred in the construction,the common finite element ANSYS9.0 software is used for analyzing the local stress under the anchorage of this bridge in casted side spans.Results of the analysis showed that too much vertical side spans prestressed in bottom slab is the main reason causing cracking.


Cabbage transplants were planted on 29 Aug at the Eastern Shore Agricultural Experiment Station, Painter, Va. Each plot consisted of two 30-ft-long rows bordered on each side by an untreated row. Cabbage was transplanted with 17-inch plant and 36-inch row spacing. Treatments were replicated 4 times in a randomized complete block design. Sprays were applied with a propane compressed-gas backpack sprayer using 3 hollow cone nozzles/row and delivering 70 gal water/acre at 40 psi. Applications were made on 23 and 29 Sep and 7 and 14 Oct. Evaluation criteria consisted of direct counts of ICW, CL, and DBM larvae on 5 randomly chosen plants/treatment. On 27 Oct, damage ratings were determined as in Greene et al. (J. Econ. Entomol., 62(4): 798-800, 1970). Plants with a damage rating of 3 or below were considered marketable.

The paper presents the importance of mathematics and its relation to improving innovation andtechnological advancement in developing countries. The rapid rise in technology, together with the laborforce, is practically changing, especially in developing countries where the demand for innovative localsolutions to indigenous problems, is now being promoted and encouraged through research. This requiresadvanced knowledge in scientific courses, most especially mathematics. Furthermore, in acquiring newskills or transitioning between professions, different skills are needed where mathematical modelling of theproblem can help in trying to make sense of situations.The study shows that there exists a relationship between mathematical performance, training environment aswell as the quality of teaching, which affects student's progress. This will further help in developing a morerobust framework to help students embrace mathematics analysis as well as themselves with the necessaryscientific numerical skillset essential for innovation and development


Significance Exogenous metabolites have been documented to potentiate antibiotics to kill multidrug-resistant pathogens, but the mechanisms are largely unknown. The work presented here shows that intermetabolites from the TCA cycle and the phosphoenolpyruvate (PEP)-pyruvate-AcCoA pathway have the potential to improve targeting of these resistant microorganisms. The enzymes that connect the PEP-pyruvate-AcCoA pathway to the TCA cycle are essential for this potentiation, indicating both pathway and cycle can be merged to be considered a pyruvate cycle (P cycle). The P cycle operates routinely as a general mechanism for energy production and regulating the TCA cycle in Escherichia coli and Edwardsiella tarda. The results reported here provide insights into metabolite-facilitated targeting by antibiotics as well as bacterial energy metabolism and homeostasis. The emergence and ongoing spread of multidrug-resistant bacteria puts humans and other species at risk for potentially lethal infections. Thus, novel antibiotics or alternative approaches are needed to target drug-resistant bacteria, and metabolic modulation has been documented to improve antibiotic efficacy, but the relevant metabolic mechanisms require more studies. Here, we show that glutamate potentiates aminoglycoside antibiotics, resulting in improved elimination of antibiotic-resistant pathogens. When exploring the metabolic flux of glutamate, it was found that the enzymes that link the phosphoenolpyruvate (PEP)-pyruvate-AcCoA pathway to the TCA cycle were key players in this increased efficacy. Together, the PEP-pyruvate-AcCoA pathway and TCA cycle can be considered the pyruvate cycle (P cycle). Our results show that inhibition or gene depletion of the enzymes in the P cycle shut down the TCA cycle even in the presence of excess carbon sources, and that the P cycle operates routinely as a general mechanism for energy production and regulation in Escherichia coli and Edwardsiella tarda. These findings address metabolic mechanisms of metabolite-induced potentiation and fundamental questions about bacterial biochemistry and energy metabolism.

Many scientific and technological advances require the values of a set of parameters to be constrained or estimated using recorded data. It is often possible to model data that would be recorded for particular parameter values using a computable and in general nonlinear function, where its inverse is unknown and does not exist as a unique-valued mapping. The space of parameter values must then be explored to find values that are consistent with measured data. This may be achieved by sampling values at a sufficiently dense set of points in parameter space, evaluating the forward function for each sample, and testing their modelled data against the measured data. For many-parameter (highdimensional) systems, achieving sufficient sample density may be infeasible due to the 'curse of dimensionality' – the exponential increase in sampling required to achieve similar sample density in spaces of increasing dimensionality. However, this article shows that for each sample, significantly more information may be available than the forward function evaluation alone, due to symmetries and other properties of the physical system. Call this additional information the extension of a sample. In travel time tomographic imaging, the extension of every sample provides forward function values throughout continuous parameter semi-subspaces. The dimensionality of these subspaces increases exponentially with the dimensionality of the problem, almost matching the rate of information increase required by the so-called curse of dimensionality. The use of extensions within Physics-based sampling schemes may therefore contribute to increase the dimensionality of problems in which one can explore parameter space, solve inverse or inference problems, or provide distributed information about forward function values directly.


A model is presented which relates medium grain size to the system BER degradation caused by media thermal decay. A simple model is used to calculate the magnetization and playback signal decay specifically focusing on grain size distributions. These results are utilized to determine signal to noise ratio (SNR) and bit error rate (BER) over a 10-year period for a recording density near 50 Gbit/in/sup 2/. In our calculation, both DC and transition noise are included. Typically, the DC noise increases more rapidly with storage time than the transition noise decreases. Because of the trade off between DC and transition noise, the relation between BER and SNR is complicated.


Recently, Belle II announced evidence for the decay $B^+\to K^+ \nu \bar{\nu}$ at $3.6\sigma$ significance, and measured the corresponding decay branching ratio to be $2.4\times 10^{-5}$, which is $2.8\sigma$ above the standard-model prediction. Here, we provide a theoretical explanation based on a massless bino in R-parity-violating (RPV) supersymmetry. With a single non-vanishing RPV coupling $\lambda'_{i23/i32}$, $\lambda'_{i13/i33}$, or $\lambda'_{i12/i22}$, where $i=1,2,3$, the decay $B^+\to K^+ \overset{\scriptscriptstyle(-)}{\nu} \tilde{\chi}^0_1$ can be induced, which would lead to the same signature as $B^+\to K^+ \nu \bar{\nu}$. Taking into account both theoretical and experimental uncertainties, we derive the parts of the parameter space of the RPV coupling and sfermion masses that could accommodate the new measurement at various significance levels.


This paper presents a vision system to measure the wear of the railroad wheels, developed for the Portuguese railway company, CP - Comboios Portugal. The developed system is based on image-processing techniques to measure automatically the railroad wheels. The wheel's profile is acquired by the illumination of the wheel through a secant horizontal light plane. The profile's image is processed by identifying the line of the greatest light gradient. The gradient's profile is then converted to the wheel's radial profile by means of a coordinate transformation model, which transforms the image plane into the wheel's radial plane. A 1 : 1 scale static prototype is built and the calibration and testing procedures are shown. Experimental results are presented and discussed. Future improvements on the developed prototype will allow dynamic measurements at slow speeds 5 km/h, as the present developed image system was designed to eliminate distortions owing to the wheel's movement.


In December 1832, less than a year before the British Parliament passed the first imperial slave emancipation bill, an all-white jury in the British Caribbean colony of Barbados convicted a black, enslaved man named Robert James of having robbed and sexually violated Margaret Higginbotham, an impoverished white widow and mother. Since Robert James was a black man accused of raping a white woman the jury's decision could hardly have surprised anyone and his rapid dispatch by a hangman must have been universally expected.

This paper examines the Tense, Mood, Aspect (henceforth, TMA) markers of the Santiago variety of Cape Verdean Creole and focuses on the diachronic development as well as the grammaticalization process that a subset of the markers underwent. We propose that some of the variants pertaining to the expression of the present progressive and of anteriority are traceable to Old Portuguese. With regard to the present progressive markers, we start with the uncontroversial assumption that some of the forms are derived from the Portuguese verb 'estar' but also show that this verb has actually undergone grammaticalization in stages and layers. We propose that some of the forms were likely present in the early stages of creole formation and that others appeared later but that in the end, all forms are preserved in the language and conglomerate in a cluster of variants expressing the same semantics. We offer in this paper a quantitative analysis of the variants, emphasizing their frequency rates in our corpus; we then explore the parameters of grammaticalization offered in Heine & Kuteva (2005) to account for the present forms.


A fully relativistic stream superposition model is employed to conduct a linear numerical simulation of a self-consistently confined sheet of collisionless, neutral plasma. This multi-stream model employs a novel variable termed the 'canonical momentum potential' (or 'action function') to follow the ion and electron dynamics. For the classic, unsheared sheet pinch, growth rates obtained for the tearing instability are in reasonable agreement with previous estimates using an approximate Vlasov approach. Current shear is then introduced into the sheet and growth rates are again measured. Stabilization of the shorter wavelength modes is observed.


Modern mobile devices are equipped with input and sensor options that allow for user generated content, which can be used to create examples of real life learning situations, or authentic learning examples. However, existing research shows a gap between the creation of authentic learning examples and their subsequent reuse as learning objects. Therefore, the goal of this research is to design a mechanism to author authentic learning examples in a standardized format to enable reuse using mobile devices. The implementation, Mobile Authentic Authoring in IMS (MAAIMS), captures authentic learning examples with the mobile device sensors (still camera, video camera, microphone) which can be supplemented with location-aware GPS coordinates and other descriptive metadata following IMS Metadata specifications. MAAIMS encapsulates these authentic learning examples and employs them as standardized learning objects (IMS Content Packages), and optionally as, standardized learning activities (IMS Learning Designs). The mechanism allows for sharing and reuse of authentically created learning examples and learning activities in multiple contexts.

Recently, tower crane safety focused on anti-collision as the construction environment and group of tower crane got more and more complex. The mainstream anti-collision method used at domestic and overseas was still a passive security model represented by working area limitation technology, which lacked flexibility, initiative and portability. Other on-going researches which adopted more advanced sensors, communication techniques, intelligence algorithm couldn't use in construction practice successfully, However, some research had been done about the ultrasonic sensor used to locate the obstacles. Because that it was only ranging no direction-finding and low precision, to locate an obstacle effectively, system calculated the location with the data of difference sensors to same obstacles through adding the quantity of sensors usually (multi-sensor fusion). But the method had some bottleneck problem such as information redundancy, accumulative error, data association etc. Through analyzing nonlinear and complex relationship between the measurement time series of ultrasonic sensor and the profile of the obstacle. This paper presented innovatively a practical method that used neural network to locate the obstacle in real time and high precision via measurement time series of ultrasonic sensor. When detecting either multiple types of stationary or moving objects, It was verified successfully that the method could solves all bottleneck problems of multi-sensor fusion, reduces the quantity and the fixing precision of sensor, increases the running speed and effectiveness of system. The recognition technology was better than multi-sensor fusion and could satisfy the requirement of tower crane safety via test.

The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and t he rein lies their strength. They are radical. Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality. (H. Minkowski, address on Space and Time in Einstein's Special Theory of Relativity, 1908)


Evidence of copper's (Cu) involvement in Alzheimer's disease (AD) is available, but information on Cu involvement in microglia and astrocytes during the course of AD has yet to be structurally discussed. This review deals with this matter in an attempt to provide an updated discussion on the role of reactive glia challenged by excess labile Cu in a wide picture that embraces all the major processes identified as playing a role in toxicity induced by an imbalance of Cu in AD.


With the rapid increase in the promotion and application volume of new energy vehicles in China, the number of end-of-life new energy vehicles will increase rapidly in the future.

This paper analyzes the dismantling technology of end-of-life new energy vehicles in China and abroad, and forecasts the inventory of new energy vehicles and the number of end-of-life new energy vehicle in the future, which has important reference significance for the future development of China's industry. Finally, the paper puts forward suggestions to promote the development of the industry.


To predict the effect of active control on aircraft or helicopter trim panels, made with honeycomb sandwich composite, one approach consists in modeling the panel by Finite Element Method. FEM with shell elements for the laminate and volume elements for the core is classically used in industry. The aim of the present study is to determine the limits of the Shell-Volume-Shell model, in case of honeycomb core, through numerical correlation with a very detailed three dimensional model. More precisely, the influence of glue stiffness by numerical simulation has been considered, and the temperature influence has been observed through modal tests inside a controlled environment chamber.


Manufacturing data is a massive amount of data generated in the application of manufacturing informatization based on the multi-value chain of the manufacturing industry. The multi-source heterogeneity of data poses a great challenge to manufacturing data management. Based on the analysis of data space theory, this paper constructs a collaborative data management system architecture of manufacturing multi-value chain based on data space, and establishes an intelligent prediction model of product sales based on data management system. Taking the products of power equipment manufacturing enterprises as an example, this paper first extracts and filters the data sets related to product sales from the multi-value chain collaborative data space of the manufacturing industry. The sparrow search algorithm was used to optimize the extreme learning machine model to predict product sales, which verifies the effectiveness of the multi-value chain collaborative data management system based on data space. This provides guidance for making the next production plan.
