OBJECTIVE To identify and integrate the available scientific evidence related to the use of the prone position in patients with acute respiratory distress syndrome for the reduction of the outcome variable of mortality compared to the dorsal decubitus position. METHOD Overview of systematic reviews or meta-analyzes of randomized clinical trials. It included studies that evaluated the use of p...

In an attempt to understand the structural characteristics of phenolic compounds that favour the inhibition of 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) formation, this study analyzes the role of twenty-five phenolic compounds on the PhIP produced in phenylalanine/creatinine/oxidised lipid reaction mixtures. The results showed that phenols having two hydroxy groups at meta position...

The goal of this project is to develop an intelligent, adaptive Web search tool. Our work is based on ProFusion, a Web meta-search engine developed at the University of Kansas. ProFusion analyzes incoming queries, categorizes them, and automatically picks the best search engines for the query based on a priori knowledge (confidence factors) which represents the suitability of each search engine...

Multi-agent systems can be viewed as object-oriented systems in which their entities show an autonomous behavior. If objects could acquire such skill in a flexible way, agents could be built exploiting object-oriented techniques and tools. There are several ways for building agents from objects: defining common interfaces and behavior in abstract superclasses, wrapping objects with agent behavi...

This review analyzes trends and commonalities among prominent theories of media effects. On the basis of exemplary meta-analyses of media effects and bibliometric studies of well-cited theories, we identify and discuss five features of media effects theories as well as their empirical support. Each of these features specifies the conditions under which media may produce effects on certain types...

The published works of scientists often conceal the cognitive processes that led to their results. Scholars of mathematical practice must therefore seek out less obvious sources. This article analyzes a widely circulated mathematical joke, comprising a list of spurious proof types. An account is proposed in terms of argumentation schemes: stereotypical patterns of reasoning, which may be accomp...

Mapping of jobs to the resources in grid environment is computed under high degree of heterogeneity of resources due to which heuristic and meta-heuristic approaches are the feasible methods to scheduling in grids. In this paper we enhance the genetic based scheduling in computational grids by a bacterial foraging optimization algorithm in grid environment. This paper analyzes the run-length un...

Information and communication technologies (ICT) are becoming increasingly important for the provision of public services. Therefore, public-private partnerships (PPP) have become a valuable alternative for implementing, maintaining, and modernizing public ICT infrastructures. However, information technology (IT) partnerships between public and private parties are difficult endeavours due to di...

of 3.5-5 months. Historically, radiotherapy alone has been the standard treatment for PCNSL; however, radiotherapy is rarely a curative treatment in PCNSL patients since response is usually short-lived, with a median survival of 12-14 months.12,13 Moreover, the positive impact of chemotherapy progressively limited the indications for radiotherapy alone. Current therapeutic knowledge in PCNSL re...

The success of system modernization depends on the existence of technical frameworks for information integration and tool interoperation like the Model Driven Architecture (MDA). Reverse engineering techniques play a crucial role in system modernization. This paper describes how to reverse engineering activity diagrams from object oriented code in the MDA context focusing on transformations at ...
