Objective: It is believed that drivers play a crucial role in accidents. Paying attention to brake lights, a driver may find out about danger and react. Rear-end collision accidents refer to the part of the accidents due to driver inattention or slow reaction. The aim of this study was to determine the effect of dynamic flashing brake lights (7 Hz) on drivers' brake reaction time using the driv...

Asbestos body (AB) concentrations in bronchoalveolar lavage samples of 15 brake lining (BL) workers exposed only to chrysotile have been determined and compared with those from 44 asbestos cement (AC) workers extensively exposed to amphiboles. The mean AB concentrations (263 +/- 802 and 842 +/- 2086 AB/ml respectively) for those groups did not differ significantly but were much higher than thos...

Hybrid materials collected from organic and inorganic sources, which are traditionally used as brake lining materials, generally include fly ash, cashew shell powder, phenolic resins, aluminium wool, barites, lime carbon powder copper powder. The present research focuses on the specific effects produced by ash aims to provide useful indications for replacement of asbestos due health hazards cau...

A high risk for the development of diffuse pleural mesothelioma is known to exist in various occupational settings associated with the use of asbestos.' Although a serious hazard has been recognised among asbestos miners, millers, and shipyard workers, recent evidence suggests that a high risk of mesothelioma may exist among occupational groups previously thought to be at low risk for developin...

Brake pad components are important in two-wheeled vehicles because they concern the driver's and others' safety. lining wear is an unavoidable phenomenon. This of concept braking, which involves bringing two things into contact with each other such that press against rub other. pads have not been replaced make brakes unable to work normally, so potential for accidents even greater. One factors ...

JAK-STAT signaling mediates the actions of numerous cytokines and growth factors, and its endogenous brake is the family of SOCS proteins. Consistent with their intracellular roles, SOCS proteins have never been identified in the extracellular space. Here we report that alveolar macrophages can secrete SOCS1 and -3 in exosomes and microparticles, respectively, for uptake by alveolar epithelial ...

The joints between segmental rings can withstand a certain amount of bending moment as well as axial and shear forces. Generally, in the structural analysis of tunnel segmental lining, the joints can be modeled as elastic hinges or rotational springs, and their rigidity should be demonstrated in terms of the rigidity of the joints or their rotational stiffness. Therefore, the bending moment act...

For the sake of high-efficiency energy recycling and brake security for series-parallel hybrid electric vehicle, an integrated brake system with an electric consuming brake subsystem and advanced strategy is proposed. The specific structure of electric consuming brake subsystem is introduced. The brake processes in different brake conditions are analyzed. A brake control strategy relying on the...
