Earthquake force, loading more than structural capacity, cracking, material fatigue and the other unpredicted events were undeniable in the structure life cycle in order that environmental conditions of the structure would be changed and treats health. Damage of structures such as crack, corrosion of the post tension cables from inappropriate grouting of the post tension structures and etc. can...

stroke is one of the most leading causes of death and disability in the world. complement system activation contributes to pathogenesis and neuronal damage following stroke. there are no defined biological serum markers to determine the severity of stroke in acute phases. the purpose of current study was to determine the association of three complement activators, namely pentraxin-3 (ptx3),m-fi...

spring summer 2010, vol.4, no.1 /74 medical laboratory journal severity of oxidative dna damage in gastric tissue of smoker and non-smoker patients with dyspepsia abstract background and objectives: cigarette smoking is associated with an increase in risk of peptic ulcer and gastro-intestinal cancer. toxic materials in smoke and tar have a significant role in production of carcinogenic complexe...

One of the serious damages of tremendous earthquakes is the damage to bridges as the major components in an    arterial road network, as relief operation is interrupted following cutting roads. Regardless of the magnitude and severity of an earthquake, other factors are also important in the strength and seismic performance of concrete bridges. Freezing-thawing cycles are among the factors, whi...

Damage to residual stand is unavoidable and it is one of the main important issues in the forest harvesting. Trees damage may occur in felling and skidding work phase or during skid trail construction. In any case, damage can be very serious to residual stand. Detailed study is necessary to find out the amount and severity of damage to trees; therefore district 14 of Kilesara in Guilan Province...

background: motor vehicle crashes (mvc) are considered to be the most common safety challenge, causing more than a million deaths worldwide annually. objectives: the current study was aimed at identifying the etiological role of human and vehicle safety factors in road crashes, and their effects on the severity of injury and fatality in the sistan and baluchistan province, south east iran. pati...

This paper presents a new method for detecting beam and frame damage caused by an earthquake. Despite comprehensive investigations on structural damage detection, which mostly have focused on damage detection of elastic structures, the present study deals with nonlinear damage detection in structures. Furthermore, in the proposed method, only measurements of the damaged structures during an ear...
