To evaluate the suitability of C++ for safety-critical applications [Bin95] and to formulate guidelines for its use in these, the concept of a safety-critical application must first be defined. A safety-critical application [HIS99, Saf00] is one where failure to stay within the bounds of safe operation leads to unacceptable results. Unacceptable results are those which pose a threat to human li...

Level of Service of Safety is a new concept in the field of traffic safety in China and developed countries, it is a quality indicator which is used to describe the road traffic safety situation and roads providing service of traffic safety for traffic participants. Introducing the study status of the Level of Service of Safety in China and developed countries, the definition of the concept, ap...

We reconcile the findings of Holmes et al. (Ecology Letters, 10, 2007, 1182) that 95% confidence intervals for quasi-extinction risk were narrow for many vertebrates of conservation concern, with previous theory predicting wide confidence intervals. We extend previous theory, concerning the precision of quasi-extinction estimates as a function of population dynamic parameters, prediction interv...

The central role of small RNAs in regulating bacterial gene expression has been elucidated in the past years. Typically, small RNAs act via specific basepairing with target mRNAs, leading to modulation of translation initiation and mRNA stability. Quantitative studies suggest that small RNA regulation is characterized by unique features, which allow it to complement regulation at the transcript...

Physicians working in hospitals face challenges when it comes to understanding and meeting the medical, legal, and ethical subjects outlined in the hospital bylaws. Hospital staff physicians and the hospital administration both aspire for high quality medical care and the assurance of patient safety. Unfortunately, when quality concerns surface, there can be reasonable differences of opinion as...

Background: Cereals are the most staple foods in human diet and the main components of the daily diet. This work was designed to determine the level of essential and non-essential elements, the in vitro bioavailability, interrelationship, and associated health risk in consumed cereal grains in Nigeria to assess their safety and wholesomeness. Methods: The contents of phytate, oxalate, and some...

to evaluate the effect of different rates of nitrogen fertilizer on competitive ability of canola (okapi cv.) in interference with wild mustard, a split-plot experiment based on a randomized complete block design with 3 replications was carried out at agricultural faculty of bu-ali sina university, in 2008-2009. 4 levels of nitrogen fertilization (100, 150, 200 and 250 kg n ha-1) were assigned ...

Preliminary work on the development of measures appropriate for the safety domain is reported. Measures are expressed in the style of the Practical Software and Systems Measurement (PSM) approach, a programme sponsored by the US DoD. Proposed measures are integrated with the PSM measurement framework. Reported work has been informed by discussions within the PSM community and by concurrent work...

farming organic vegetable and crops have grown as a market desiring commodity. weed control in farms has been costly and laborous and it has always been hard to achieve a proper weeding. a few chemicals are commonly applied in organic farming. thermal weeding with flame burners seems a good solution; however, it has its own drawbacks, such as; damaging the main crops, low performance, being inf...
