Studies using post mortem human subjects (PMHS) are conducted for the design and evaluation of dummies. Biomechanical variables such as forces, accelerations, and deflections are used to characterize responses under simulated environments including frontal, rear, nearside and far-side impacts. The present paper is focused on the nearside occupant. Chest and abdominal deflections are important v...

linear dynamic response of simply supported nanobeams subjected to a variable axial force is assessed by galerkin numerical approach. constitutive behavior is described by three functional forms of elastic energy densities enclosing nonlocal and strain gradient effects and their combination. linear stationary dynamics of nanobeams is modulated by an axial force which controls the global stiffne...

The goal of this study is to prospectively assess the additional value of oblique reformatted images for localizing POT, having surgery as a reference standard. Materials and Methods. 102 consecutive patients with suspected small bowel obstruction (SBO) underwent 64-slice multidetector row CT (MDCT) using surgical findings as reference standard. Two independent GI radiologists reviewed the CT s...

There have been numerous researchers that have investigated the properties of human intervertebral discs. However, there has been no attempt to characterize the effects of dynamic loading on the compressive stiffness of human lumbar intervertebral discs. Therefore, the purpose of this study was to develop the compressive stiffness properties of lumbar intervertebral discs when subjected to vari...

This study aimed to evaluate the influence of the type of prosthetic abutment associated to different implant connection on bone biomechanical behavior of immediately and delayed loaded implants. Computed tomography-based finite element models comprising a mandible with a single molar implant were created with different types of prosthetic abutment (UCLA or conical), implant connection (externa...

The effect of slice orientation on reproducibility and sensitivity of 3T fMRI activation using a motor task has been investigated in six normal volunteers. Four slice orientations were used; axial, oblique axial, coronal and sagittal. We applied analysis of variance (ANOVA) to suprathreshold voxel statistics to quantify variability in activation between orientations and between subjects. We als...

High-resolution surface-coil MR imaging reveals intricate anatomic detail of the cervical spinal canal and its neurovascular contents. Appreciation of the normal neurovascular anatomy provides a scientific foundation for the detection of disease. Sagittal, axial, and oblique MR images of normal subjects were correlated with comparable anatomic sections obtained with a cryomicrotome whole-organ ...

The use of timber in structures like guard-rail systems requires knowledge about the behaviour at high loading rates. The present study aims at presenting a state of art report with respect to the impact bending strength of timber and to some extent to the behaviour of timber joints at high loading rates. The literature review indicates a difference in the experimental results and the conclusio...
