Background: Renal osteodystrophy (ROD) is a common bone and mineral metabolism disorder in patients with end-stage renal disease (ESRD). This study aimed to determinate the frequency of the subtypes of ROD and evaluate the diagnostic value of biochemical as the well as radiographic markers for the diagnosis of ROD among hemodialysis patients in Golestan province of Iran.  Materials and Methods...

An open resonance cell (ORC) with finite-length cylindrical mirrors is suggested for making absolute measurements of complex permittivity in the case of stretched cylindrical specimens or liquid dielectrics in cylindrical containers. For H-polarization, we report ORC features simulated in rigorous electromagnetic terms using a twodimensional (2-D) model of an open resonator with cylindrical mir...

Skull fractures are quite often observed in victims of falls, traffic accidents, attacks with the use bats and rods. The aim study is to assess stress-strain state human head under impact on basis finite element modelling. applied frontal region bone by middle part end a cylindrical solid (a rod). differently oriented respect relation Frankfurt plane. model includes epidermis (skin), structures...

In the process of heat transfer by conduction, besides quantities in form surface area, length or thickness rod, and temperature difference between ends rod value thermal conductivity, other factors also affect rate to one which is environmental factors. As long as flows from high low temperature, decrease not uniform at any time interval. This a sign influence ambient for each part material. T...

Spinal fusion is the gold standard treatment for severe pathologies in lumbar spine. However, fusion can yield adverse effects, such as Adjacent Segment Degeneration (ASD). Alternatively, non-fusion techniques were proposed. Although infrequent, mechanical complications were reported such as screw loosening and screw breakages. This work aims to use Finite Element Model (FEM) to investigate imp...

We present a hybrid fluid-particle algorithm to simulate flow and transport of DNA-laden fluids in microdevices. Relevant length scales in microfluidic systems range from characteristic channel sizes of millimeters to micron scale geometric variation (e.g., post arrays) to 10 nanometers for the length of a single rod in a bead-rod polymer representation of a biological material such as DNA. The...
