The fracture mechanics parameters are used in different applications to formulae the classic criteria of failure as well as in computational models to analyze the concrete structures and other brittle materials. The parameters are determined using the specimens with notches. The study for assessing the influence of the notch curvature in specimen on fracture mechanics parameters, e.g. critical ...

Variable-depth streamer acquisition is now widely used, achieving a bandwidth of more than 6 octaves (2.5 to 200 Hz) and excellent lateral resolution and providing improved impedance and reservoir analysis. This acquisition and processing method is based on towing the streamer deep, using a variable-depth profile optimized to ensure receiver notch diversity at the imaging stage and a deghosting...

Background: The distinctive morphology of human skeleton and its clear sexual dimorphism make it interests from anatomical, forensic, obstetrical, radiological anthropological point view. hip bone is considered as an ideal for sex determination provides the highest accuracy levels. Many workers have studied various metric parameters sexing bone.
 Methods: present study was done with aim to...

Obstetric vasculopathies are a set of apparently heterogeneous and poorly understood conditions. Conditions like recurrent miscarriages due to fetal demise, pre-eclampsia, IUGR, recurrent still births and accidental hemorrhage all seem to have the same underlying etiopathology. They are grouped into one large set coined as ‘Obstetric Vasculopathies’. Resistance to blood flow in the uterine arte...

The light weight of magnesium alloys makes them a promising material in different potential industries, such as aerospace and automobile. In addition, are attractive materials for biomedical applications due to their biocompatibility with the human body. these structural parts require an understanding fatigue behavior because they usually subjected time-varying loading. Furthermore, notches ine...

Purpose: This study aimed to relate the level of physical force applied to the arterial wall by atraumatic clamps to the degree of endothelial and wall damage. Methods: Sixteen sheep carotid and femoral arteries were each demarcated into four segments 1 cm apart (total 64 segments). Each segment was clamped for 15 min with a standard angled DeBakey vascular clamp. Four levels of force were gene...
