Abstract Glass fiber-reinforced polymer materials have been effectively used in civil aviation aircraft, but due to low electrical conductivity, a large area of ablation damage will occur after lightning strikes, which greatly threatens the safety aircrafts. Based on this, coupled electrical-thermal finite element analysis model for glass fiber reinforced is established, and results are compare...

New research from California confirms the safety of pasteurized mother’s milk for HIV-exposed babies (Israel-Ballard, 2005). Two methods of heat-treatment, known as Flash-Heating and Pretoria Pasteurization, were compared to assess their impact on HIV and antimicrobial properties of breast milk, as well as on nutrient content.Milk samples were spiked with clade C HIV-1 (the sub-type found in ar...

capable of accurate adjustment and dosage, at the same time simple in construction, and as far as possible reliable in its action, they started experimenting in March of this year. The first piece of the apparatus to be taken in hand was the safety valve. Those familiar with the intratracheal method of administering anaesthetics well know that an efficient safety valve is a sine qua non. Two ty...

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...

Increased global urbanization has caused tall buildings to become an inevitable building form making the façade and especially the glazing areas of paramount importance for the overall heat loss and heat gain of the building. The substantial technological advances in insulating glass and glazing systems made during the past 25 years have improved the possibility for designing well-functioning b...

Air abrasion as a caries removal technique is less aggressive than conventional techniques and is compatible for use with adhesive restorative materials. Alumina, while being currently the most common abrasive used for cutting, has controversial health and safety issues and no remineralisation properties. The alternative, a bioactive glass, 45S5, has the advantage of promoting hard tissue remin...

BACKGROUND The aim of this study was to evaluate the ability of 15 serotypes of Salmonella to form biofilm on polystyrene, polyvinyl chloride (PVC) and glass surfaces. . METHODS Initially slime production was assessed on CRA agar and hydrophobicity of 20 Salmonella strains isolated from poultry and human and two Salmonella enterica serovar Typhimurium references strains was achieved by microb...

Safety cases offer a means for communicating information about the system safety among the system stakeholders. Recently, the requirement for a safety case has been considered by regulators for safety-critical systems. Adopting safety cases is necessarily dependent on the value added for regulatory authorities. In this work, we outline a structured approach for assessing the level of sufficienc...

materials used in the body, especially the materials used in various oral cavity regions should be stable and passive without any interactions with the body tissues or fluids. dental amalgam, c omposite resins and dental cements are the materials of choice with such properties. the first attempts to produce active materials, which could interact with the human body tissues and fluids were promp...
