The majority of industrial enzymes available at present is used in food industry. Safety regulations of food enzymes differ among countries, including fundamental aspects, whether a pre-market approval is needed and on the level of details, e.g. what particular information manufacturers have to provide in the course of safety evaluation. Occupational safety concerns focus on allergenic properti...

in this paper, acceptance criteria of steel building code, comprehensive and quick evaluation procedures for x-bracing, are compared to each other parametrically and numerically. for this purpose, it is assumed first that the sample building is designed to meet steel building code and then by introducing transform parameters and using stress ratio of the designed components, acceptance of the d...

PARTICIPANTS/SETTING Kindergarten students at 10 urban elementary schools. DESIGN Each school was randomized to either the intervention or control group. An evaluation tool...

The SISTEMA software utility (Safety Integrity Software Tool for the Evaluation of Machine Applications) provides developers and testers of safety-related machine controls with comprehensive support in the evaluation of safety in the context of EN ISO 13849-1. The tool, which runs on Windows, enables users to model the structure of the safety-related parts of control systems (SRP/CS) based upon...

Patient safety leadership walkarounds (PSLWA) have been identified as an effective tool to improve patient safety culture. At Hamilton Health Sciences, after one year of monthly PSLWA in all clinical and service programs, 1,351 patient safety issues were identified, of which 64-80% have been resolved or have active improvement work in progress. Five hundred staff were invited to complete a proc...

In contrast to the situation in the USA, where a wide range of genetically modified (GM) foods is available, in Europe very few GM products have been approved for marketing as foods, and there is widespread public concern about their safety and environmental impact. The marketing of a GM crop for food use in Europe falls under the EC novel foods regulations, and applications require the submiss...

A comprehensive program for the evaluation and enhancement of seismic safety of the Paks Nuclear Power Plant was started in 1993 and now is in progress. In the first two years of the program the urgent and quickly realizable fixes were performed, seismic instrumentation was installed, and a procedure was elaborated for the activities to be performed after a possible earthquake. Re-evaluation of...

Accurate real-time crash risk evaluation is essential for making prevention strategy in order to proactively improve traffic safety. Quite a number of models have been developed to evaluate traffic crash risk, by using real-time surveillance data. In this paper, the basic idea of traffic safety region is introduced into highway crash risk evaluation. Traffic safety region aims to describe the s...

Background: Plasmapheresis is a well-recognised method for harvestingplasma.  It was introduced in the 1950s and is currently employed worldwide.  This method has been in use in Iran since 1979. Objective: To evaluate the efficacy of donor safety program used at the Iranian Blood Transfusion Organization. Methods: A comparison is made of the protein concentrations between the first-time and lon...
