Bias Voltage Dependency of Structural and Bipolar Plate-Related Properties of Cathodic Arc-Deposited Carbon-Based Coatings.

Carbon-based coatings composed of a chromium interlayer and a carbon top layer were deposited on stainless steel substrates via cathodic arc evaporation. During the carbon deposition, the bias voltage was varied between 900 and 1 V to investigate the influence on the structural, electrical, and electrochemical properties. Raman spectroscopy indicated a dependency of the intensity ratio and G peak position on the bias voltage, which can be attributed to an alteration of the structure.

A case-control study on risk factors of domestic accidents in an elderly population.

The aim of this study was to evaluate the combined influence of several lifestyle, health and housing factors in the occurrence of home injuries (HIs) among the elderly. The subjects were recruited from 10 hospitals in Rome, Italy. This study is a paired case-control study.

Unintentional home injuries reported by an emergency-based surveillance system: incidence, hospitalisation rate and mortality.

Objective: The aim of this study is to quantify the incidence of home injuries using an integrated surveillance system. It aims to estimate home accident mortality.

Material And Methods: The sources of data for this epidemiological descriptive study were the emergency information system, the hospital information system and the mortality registry of Lazio Region, 2000-2001.
