Because of the recent frequency climatic hazards and extreme weather events, disasters caused by natural are attracting increased attention from governments, communities, public. Synergistic effects between technological have a significant role in risk assessment. To address these effects, Natech assessment model based on natural-technological-prone (Natech-prone) facility network is developed ...

ABSTRACT Blade failure is a common problem of a steam turbine and it’s failure in-service results in safety risks, repair cost and non operational revenue losses. Thus, the reliability of these blades is very important for the successful operation of a steam turbine. Dynamic analysis of a steam turbine blade in computational environment is carried out in the present work. In order to gain physi...

OBJECTIVE Prone positioning, iterative reconstruction (IR-OSEM) and electrocardiography (ECG) gating have been demonstrated to improve the specificity of myocardial perfusion SPECT (MPS) in the diagnosis of coronary artery disease. METHODS The gated supine and prone MPS images of 45 patients were reconstructed with both IR-OSEM [supine (SIR) and prone (PIR)] FBPs [supine (SFBP), prone (PFBP)]...

STUDY DESIGN Case-control study comparing sagittal plane segmental motion in women (n = 34) with chronic whiplash-associated disorders, Grades I-II, with women (n = 35) with chronic insidious onset neck pain and with a normal database of sagittal plane rotational and translational motion. OBJECTIVE To reveal whether women with chronic whiplash-associated disorders, Grades I-II, demonstrate ev...

Ensuring safety on roadways and controlling conflicting merging streams of traffic at signalized intersections has become a major concern for transportation engineers road users globally locally. Many factors contribute to accident occurrence segments with driver behavior being the contributor.  Other include those related vehicle road. The primary aim this study is understand impact diffe...

Road accidents have a definite impact in terms of lives, welfare and traffic congestion, especially with increase in mobility and number of overall vehicles. Prevention policies can greatly benefit from data analysis of positions and accident characteristics. This work presents a practical integration of open source software for the implementation of an instrument to insert, store, automaticall...

S100 proteins are small dimeric calcium-binding proteins which control cell cycle, growth and differentiation via interactions with different target proteins. Intrinsic disorder is a hallmark among many signaling proteins and S100 proteins have been proposed to contain disorder-prone regions. Interestingly, some S100 proteins also form amyloids: S100A8/A9 forms fibrils in prostatic inclusions a...

conclusion the chances of sustaining serious spine and associated multiple injuries in car accidents are quite high in iran. this may be due to the low level of standards or car manufacturing, absence, or inadequacy of appropriate safety measures in cars, poorly designed roads, and problems in the quality of driving to mention just a few reasons. therefore, these victims are prone to significan...
