Ubicomp applications are characterized as situation-aware, frequently-and-ephemerally-communicated and QoS-properties-associated. Using middleware to provide multiple QoS support for these ubicomp applications will enhance the development of the ubicomp applications. To satisfy the different QoS requirements of various applications in ubicomp environments, which are heterogeneous and resource-variant, it is important for the underlining middleware to adapt to different QoS requirements and environments. Situation-Aware Contract Specification Language (SA-CSL) specifies the QoS requirements of the applications. The specification includes requirements in situation-awareness, real-time constraints and security properties. This specification is used to customize the middleware architecture to better satisfy these requirements. SA-CSL is based on the Separation of Concern (SoC) discipline used in the Aspect-Oriented Software Development (AOSD). It specifies the crosscutting aspects of situation-awareness, real-time constraints and security property separately. Because of the object-oriented design, SA-CSL is open for incorporating new QoS properties specification.


This document is a concise compendium of resource material covering assured thermal processing of wastes (ATPW), an area in which Sandia aims to develop a large program. The ATPW program at Sandia is examining a wide variety of waste streams and thermal processes. Waste streams under consideration include municipal, chemical, medical, and mixed wastes. Thermal processes under consideration range from various incineration technologies to non-incineration processes such as supercritical water oxidation or molten metal technologies. Each of the chapters describes the element covered, discusses issues associated with its further development and/or utilization, presents Sandia capabilities that address these issues, and indicates important connections to other ATPW elements. The division of the field into elements was driven by the team`s desire to emphasize areas where Sandia`s capabilities can lead to major advances and is therefore somewhat unconventional. The report will be valuable to Sandians involved in further ATPW program development.

The world has the challenge of expanding electricity production meeting demand and ensuring energy security for the support and development of society. Given data and information on energy sources are available on a large scale, there is an opportunity to develop a tool that enhances and contributes to decision making in the energy sector. With this in mind, this article brings together the use of technology, finance, information and intangibles with the objective of enhancing the decision-making process for the implementation and optimization of the fuel input mix for the power industry. The results presented in the article are obtained by means of technical, economic and information management analysis that constitute the theoretical basis of intangibles, all of them supported by information technology. This article presents both a new methodology and a new software to obtain optimum investment decisions in the power industry, focusing on power production. The development and validation of the methodology and software are described. The best energy investment to be made is based on the extraction and evaluation of the knowledge of the energy sector specialist in a logical and mathematical way. The results of the research present a decision-making process based on more formal and less personal criteria, guaranteeing greater neutrality and convergence in the decision-making process.


We review the mechanisms of cardiotoxicity of cytotoxic chemotherapies, the substances associated with a partic-ular high risk of cardiac damage, the clinical signs and symptoms of cardiotoxicity with special emphasis on cardiac failure, and the prevention and therapy of possible cardiotoxic effects. Generally, chemotherapy-induced cardiotoxicity is defined as a reduction of the left-ventricular ejection fraction (LVEF) of more than 5% to less than 55 % with clinical signs of heart failure or as a reduction of the left-ventricular ejection fraction (LVEF) of more than 10% to less than 55% without clinical signs of heart failure. The cardiotoxicity of anthracyclines such as doxorubicin results in limitations of the use of this chemothera-peutic class in the treatment of malignant diseases in 5 – 20% of patients due to asymptomatic impairment of left ventricular function and in 1 – 5% of patients due to symptomatic heart failure. The common use of trastuzumab, a monoclonal antibody against " human epidermal growth factor receptor 2 " (HER2), has resulted in an in-cidence of cardiotoxicity – commonly as asymptomatic impairment of left ventricular function or even as symptomatic cardiac failure – in up to 10% with monotherapy and in up to 30% in


In running a factorial experiment, it may be desirable to use an orthogonal array with different (mixed) numbers of factor levels. Because of the orthogonality requirement, such arrays may have a large run size. By slightly sacrificing the orthogonality requirement, we can obtain nearly orthogonal arrays with economic run size. Some general methods for constructing such arrays are given. For 12, 18, 20, and 24 runs, many orthogonal arrays and nearly orthogonal arrays with mixed levels are constructed and tabulated. Effects of near orthogonality on estimation efficiency and analysis are studied.


30. (iv) In order to ensure that this paragraph aligns with para. 112, it should mention "universal" social protection. Suggested language could be: "Ensure that universal targeted social protection measures – including cash and food transfers, school feeding, pensions and social welfare measures – are also targeted and in place to...". Another option would be to move para. 112 up into this paragraph.

The fossil shrimp Araripenaeus timidus n. gen. n. sp. is the first fossil Penaeoidea from Brazil. Here, we describe, illustrate and compare it with Paleomattea deliciosa, a fossil Sergestoidea (Dendrobranchiata) previously described from the same region. The material of the early Cretaceous (Albian) was collected in the town of Jardim, south of the state of Ceará, in the superior septarian concretion level of the Romualdo Formation. Additionally, a second specimen of Kellnerius jamacaruensis was found in the same site of the Araripe Basin.


The size and shape of a large variety of polymeric particles, including biological cells, star polymers, dendrimes, and microgels, depend on the applied stresses as the particles are extremely soft. In high-density suspensions these particles deform as stressed by their neighbors, which implies that the interparticle interaction becomes of many-body type. Investigating a two-dimensional model of cell tissue, where the single particle shear modulus is related to the cell adhesion strength, here we show that the particle deformability affects the melting scenario. On increasing the temperature, stiff particles undergo a first-order solid/liquid transition, while soft ones undergo a continuous solid/hexatic transition followed by a discontinuous hexatic/liquid transition. At zero temperature the melting transition driven by the decrease of the adhesion strength occurs through two continuous transitions as in the Kosterlitz, Thouless, Halperin, Nelson, and Young scenario. Thus, there is a range of adhesion strength values where the hexatic phase is stable at zero temperature, which suggests that the intermediate phase of the epithelial-to-mesenchymal transition could be hexatic type.


We have simulated the seasonal variation of the general circulation on Mars for obliquities of 0deg and 60deg. These obliquities represent the minimum and maximum values the planet has experienced during the past 10(exp 7) years (e.g., Laskar and Robutel, 1993, Nature, 361, 608-614). The model we use is the NASA/Ames Mars General Circulation Model (Pollack et al., 1993, J. Geophys. Res. 98, 3149-3181). We vary only the obliquity; all other model parameters are as in Pollack et al. At high obliquity, the model shows dramatic seasonal variations in the polar caps and in the structure and intensity of the circulation. At the solstices the winter cap extends to the equator. Thus, surface temperatures throughout the entire winter hemisphere are fixed at the CO2 frost point. During summer surface temperatures at the poles reach 269K in the north and 295K in the south. The most notable changes to the circulation at solstice compared to our standard runs are a general weakening of the winter westerlies, a Hadley cell of greater latitudinal extent, and the development of very strong, possibly unstable, low-level jets in midlatitudes of the summer hemisphere. Surface stresses associated with these jets are sufficient to raise dust continuously. Thus, dust storms should be frequent features of the high obliquity climate. This result is independent of any desorbed regolith CO2 which would raise mean surface pressures. At zero obliquity the structure of the circulation resembles that of present day equinox conditions modulated by the varying insolation associated with orbital eccentricity. Notable features include equatorial superrotation, asymmetric Hadley cells, and stronger poleward heat fluxes in the northern hemisphere. Since the poles do not receive solar energy at any time of year, permanent caps form which extend to about 70deg in each hemisphere. However, the north permanent cap is growing at a rate 40% faster than the south cap. This is due to the differences in topography, albedo, emissivity, and heat transport in each hemisphere. Thus the zero obliquity climate system appears to be evolving toward a state in which the north cap is the dominant cap.


The purpose of this study is to search the optimal solubilization technology which could be applied to sewage sludge, and is to find the characteristics of biological hydrogen production when the sludge treated by optimal method was used as a sole substrate. As a result of the test, treatment technology mixed with alkali and ultrasonic treatment was very powerful tool for treating sewage sludge with high solubilization, and its ratio and elution rate of organic material was 0.9 and 0.076 , respectively. When the sludge treated by above optimal technology was used, 4.4 ml VSS of hydrogen was produced. Finally, When the sludge treated by above optimal technology was used, 13.4 ml VSS of hydrogen was produced under optimum pH.


The image of the Asian American whiz kid is harming our youths. The simplistic portrayal of Asian Americans as the 'overachievers,' the 'overrepresented' in higher education, and as 'overcoming' racial obstacles has cast a pernicious shadow over those who have not fared so well-Asian American and Pacific Islander (AAPI) youths who have dropped out of school, who are caught in the juvenile justice system, and those who struggle to regain the ground they may have lost in the turmoil of adolescence. The whiz-kid stereotype not only sends the message that "if these kids can do it, why can't you?" but has also fostered a longstanding neglect by the research community of the serious hardships experienced by many AAPI adolescents


Children's accounts of abuse sometimes contain descriptions of events that seem bizarre, improbable, or even impossible. This article contributes to an objective analysis of child allegations of abuse by offering 24 possible explanations (with illustrative case examples) for such statements. The central thesis of this discussion is that the existence of improbable or fantastic elements in a child's account should not result in an automatic dismissal of the child's report without consideration of the possible mechanisms underlying the fantastic material.

This is one of those books so rich and rewarding as to strongly resist precis and summary judgement. Part of the sheer profusion of the volume derives from the diversity of its contributors, ranging from younger scholars to at least one 'grand old man', from scientists to performing artists, and they are as very often nowadays in multi-authored publications a mixture ofEuropeans and Americans. The sense of profusion can only be reinforced by the large amount of music cited, printed and discussed, although it is a doggedlyintroversive canon Bach to the TwentiethCentury Masters, males every one, and given this dominating 'sound bites from the popular classics'approach, one might almost say that these studies are mercifully free of one modern popular kind of musical sound bite, opera. Further, The Practice of Performance represents an area of musical research on the rise: as John Rink rightly notes at the beginning of his Preface, 'the past few decades have witnessed a virtual explosion in scholarly writing about musical performance' (p. ix). This reviewer must also declare a particular sense of imbrication in that two of the chapters (Eric Clarke's and Rink's own) use different pieces of his research as 'evidence' in their arguments, both pieces of evidence being examples of what would doubtless nowadays be called 'formalist' music analysis. It is in fact somewhat intriguing to see work that one thought ofas pushing forward opinion now enshrined as something almost like data, something almost 'empirical'. The detailed topics of The Practice ofPerformance are many and varied. Rink has herded the twelve chapters into three areas, 'Fundamentals', 'Structure and Meaning in Performance', and 'Performance as Process' the general, the critical, and the analytical. Yet nothing can be that simple, and the editor observes that 'resonances between chapters are abundant'. For example three of the four opening chapters ('Expression in performance: generativity, perception and semiosis' by Eric Clarke, 'Musical motion and performance: theoretical and empirical perspectives' by Patrick Shove and Bruno H. Repp, and 'Deliberate practice and elite musical performance'


The study was developed to evaluate the influence of diet supplementation of a polysaccharide extract from the microalgae Porphyridium cruentum, on weight gain, digestive enzyme activity, and Litopenaeus vannamei juvenile survival. The polysaccharides crude extract from microalgae P. cruentum was added at different concentrations (0, 0.5, 1, 1.5, and 2.0%) in a commercial diet and provided to juvenile L. vannamei (6.6 ± 0.2 g). The shrimps (n = 2,000) were fed ad libitum for 30 days in circular tanks with 12 m2 of bottom area (100 shrimp tank-1) and environmental variables (temperature, salinity, dissolved oxygen, photoperiod and levels of total ammonia) were controlled. The supplemented diet with 1% crude extract was responsible for the biggest weight gain (7.28 g) in 30 days. The shrimp body muscle centesimal composition and survival were not affected by the polysaccharide extract supplementation. It was observed a shift in the activity of digestive enzymes from the hepatopancreas to the anterior midgut and mid midgut portions in shrimps with diet supplemented with 1% polysaccharide extract, which may have contributed to a better digestive efficiency. The results indicate that dietary supplementation with crude extract of P. cruentum polysaccharides in a range between 1 and 1.5% increases weight gain and enhances the activity of digestive enzymes in L. vannamei juveniles.
