mixture in a catalytic wall reactor functionalized with plasma-activated gold nanoparticle films containing well-defined Au particles of about 3.5 nm in diameter. No catalytic activity was recorded over gold nanoparticle films prepared by thermal decomposition of core-shell nanoparticles due to particle agglomeration.

The aim of this article is to estimate the disabilty prevalence for the activities of daily living (ADL), the socioeconomic and demographic characteristics and the use of health services, ...distinguishing between the population receiving assistance for ADL and not. Cross-sectional study (Encuesta de Salud de Cataluña ESCA 2006). We have analyzed 17 ADL. Differences among proportions are estimated with a 95% confidence interval to characterize the analysis groups. Logistic regression describes the explanatory variables about getting help or not. Disabilty prevalence for the ADL: 26.6% men and 48.2% in women. Of these, 79.6% is getting help. There is a socioeconomic gradient in prevalence, not being observed in relation to assistance or not. We must deepen our understanding of the phenomenon and its evolution to which the ESCA is an essential tool.
The CitScale tool is a software platform for visualizing, analyzing and comparing the impacts of smart city policies based on innovative mobility concepts in urban areas. It places emphasis on new ...automotive vehicles aimed at reducing traffic or environmental impacts. This paper introduces this traffic simulation-based tool, and two case studies developed for different scenarios in Barcelona City are briefly presented to demonstrate the capabilities of the tool when it is combined with microscopic traffic simulation software. The first case presents an extensive evaluation of new innovative vehicles (electric vehicles, bikes and three-wheeled scooters) and mobility concepts (trip-sharing). In the second one, data provided by connected cars is analyzed in order to compare different developed navigation strategies and how they affect the city. Finally, some of the obtained results from both cases are concisely presented in order to show the potential of the proposed tool.
We aimed to know the usefulness of clinical autopsy at the medical room of an emergency department in a teaching hospital.
Retrospective study of clinical autopsies performed in the emergency ...department of a teaching hospital between 1995 and 2000. We explored the correlation between clinical emergency and autopsy diagnosis.
The number of deaths was 1,484 (0.9%) among 165,662 patients attended in the emergency medical room in the study period. Of 281 autopsies (18.9%), 227 (15.3%) were judicial. Only 54 clinical autopsies (3.6%) were included. Dyspnea and chest pain, the two more frequent guide symptoms, were in concordance with the two more prevalent initial clinical diagnoses: respiratory and cardiovascular diseases. 38.9% (21 cases) of autopsies agreed with the clinical diagnosis and 14.8% (8 cases) did not agree with it. 25.9% (14 cases) of autopsies were diagnostic since the clinical diagnosis, both initial and final, was unknown. Moreover, 14.8% (8 cases) autopsies were explanatory. Furthermore, 5.6% (3 cases) of autopsies were undetermined. With regard to the main cause of death, there were 9 (16.7%) cases of previously unknown neoplasms.
The results of the present study confirm the need and usefulness of autopsy in patients dying in the medical room of emergency departments, as well as the crucial role of the clinico-pathological exercise in the definitive diagnosis of the postmortem examination.
The CitScale tool is a software platform for visualizing, analyzing and comparing the impacts of new mobility concepts in urban models with special emphasis on new automotive vehicles or those based ...on innovative mobility concepts aimed at reducing environmental impacts. CitScale is simulation software agnostic. Using traffic simulation techniques requires executing multiple independent replications for each scenario in an experimental design, and each replication generates a huge amount of data that is not easy to analyze or compare. The analysis and comparison of experiments and scenarios is based on global, link-based and path-based key performance indicators from the perspective of users and mobility authorities while covering the scope of driver-type and transport mode.
