In this study, the finite element model updating was simulated by reducing the stiffness of the members. Due to lack of access to the experimental results, the data obtained from an analytical model were used in the proposed structural damage scenarios. The updating parameters for the studied structures were defined as a reduction coefficient applied to the stiffness of the members. Parameter v...

The literature on wind damage in New Zealand forests is reviewed to investigate how abiotic and biotic factors influence damage severity, damage type, and forest recovery. Winds that damage forests tend to result from extra-tropical depressions or from topographically enhanced westerly air flows. Severe wind damage can occur when wind speeds exceed c. 110 km/hr, although investigating the relat...

OBJECTIVE To devise a reliable, sensitive method to measure joint space in vivo during dynamic loading. Additionally, to determine if dynamic joint space changes were related to the severity of long-term cartilage damage. DESIGN Subjects were 23 adult foxhounds (18 experimental, 5 control). Experimental subjects had surgically transected cranial cruciate ligaments (CCL). Dynamic joint space w...

conclusions it seems that usage of ecg rating systems such as sss at the time of admission, in addition to showing the extent of the conflict in the myocardium, can provide valuable information about prognosis, severity of myocardial damage and ventricular function in hospitalized patients. background ischemic heart disease is among the most important causes of mortality. therefore, classificat...

Morbidity and mortality from head trauma is highest among children. No animal model mimicking traumatic brain injury in children has yet been established, and the mechanisms of neuronal degeneration after traumatic injury to the developing brain are not understood. In infant rats subjected to percussion head trauma, two types of brain damage could be characterized. The first type or primary dam...

objective: ageing of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions. accelerated ageing has been recognized as a good predictor of the storability of seed lots. aged seeds show decreased vigor and produce weak seedlings that are unable to survive once reintroduced into a habitat. the characteristics of the chemical composition of...

Conventional MRI based on weighted spin-echo (SE) images aids in the diagnosis of multiple sclerosis (MS); however, MRI markers derived from SE sequences provide limited information about lesion severity and correlate poorly with patient disability assessed with clinical tests. In this study, we introduced a novel method [based on quantitative R2* (1/T2*) histograms] for estimating the severity...

mandibular canal is the most important anatomical landmark in the body of mandible which always must be considered for implant surgery in posterior mandibular region. damage to vessels and inferior alveolar nerve that passes through the mandibular canal can cause problems such as hemorrhage and neurosensory disturbances. damage to the mandibular canal can occur during implant surgery. depending...
