Regulationx t is human nature to want to protect our children from harm. Toys, car seats, sports equipment-all are designed with a child's safety in mind. Those same children, however, have been often overlooked in two critical research areas: the effects of exposure to chemicals and guidelines for prescription medications. Environmental exposure standards have usually been set according to res...

In modern design of automobile car bodies reduction in weight and maximization of the structural stiffness and passive safety are the main challenge. The ‘Tailored Blank’ has contributed to achieve a significant weight reduction in recent years. The single flat sheets are joined by Laser Welding in butt configuration without filler wire. Usually the quality of the welds is assured by precise pr...

this paper aims to investigate a new and intricate behavior of immediate follower during the lane change of leader vehicle. accordingly, the mentioned situation is a transient state in car following behavior during which the follower vehicle considerably deviates from conventional car following models for a limited time, which is a complex state including lateral and longitudinal movement simul...

car body lightening and crashworthiness are two important objectives of car design. due to their excellent performance, composite materials are extensively used in the car industries. in addition, reducing the weight of vehicle is effective in decreasing the fuel consumption. hat shape energy absorber is used in car’s doors for side impact protection. the aim of these numerical models and exper...

posttraumatic stress disorder (ptsd) is a common response to traumatic events. a cognitive model proposed that ptsd becomes chronic when individuals process the trauma in a way that leads to a sense of serious, current threat. the sense of threat arises as an outcome of excessively negative appraisals of the trauma and its sequel and a disturbance of autobiographical memory. variations in the n...

in this study, changes in speed and turbulence intensity in the wake of a peugeot model and the drag coefficient changes with increases vehicle speed in unsteady flow measured and evaluated. the blow open circuit wind tunnel to simulate fluid flow is used. disturbances and nominal maximum speed of the device, respectively is, 30 m / s and 0.01%. has been continuously increasing speed by an inve...

background and objectives: sodium dodecyl sulfate (sds) is one of the main surfactant components in detergents and cosmetics, used in high amounts as a detergent in products such as shampoos, car wash soap and toothpaste. therefore, its bioremediation by suitable microorganisms is important. alkylsulfatase is an enzyme that hydrolyses sulfate -ester bonds to give inorganic sulfate and alcohol. ...

electromagnetic radiation emitted by cell-phones is a new health hazard, especially when they are used inside closed metal bodies such as cars, elevators etc. the modern wireless devices like bluetooth further enhance the effect of this radiation. the present studies were taken to get quantitative information about the actual power density levels to which a human brain is exposed inside a vehic...

Purpose: To ensure the accessibility for population groups with reduced mobility of facilities and services in sphere railway transport that will provide their as well possibility to access various objects (medical, educational, cultural, etc.) Methods: Analysis evaluation requirements legislative, regulatory industrial technical documents equal other citizens rights on Russian Federation Const...

The appearance of interstellar objects (ISOs) in the solar system—and specifically arrival 1I/'Oumuamua—points to a significant number density free-floating bodies neighborhood. We review details 'Oumuamua's pre-encounter Galactic orbit, which intersected system at very nearly its maximum vertical and radial excursion relative plane. These kinematic features are strongly emblematic nearby young...
