For superficial lesions, the electrons may be used for radiation therapy. The high energy photons and electrons are produced by a Linear accelerator (Linac). Many of electron fields need the shielding of normal or critical organs. The electron shields are usually lead slabs with few millimeter thicknesses which should be placed near the skin, less than 1 cm away from skin. In the inspection of ...

Appropriate glass systems can provide efficient transparent radiation shielding. The current study involved the preparation of system with a composition xEu2O3-(15-x)ZnO-10CaO-35PbO-40P2O5 (where x = 0, 1, 2, 3, and 4 wt.% Eu2O3). formation phase was confirmed using X-ray diffraction (XRD). analyzed physical structural parameters, such as optical conductivity (σopt), refractive index (n), band ...

X-ray shields used for medical purposes are manufactured using lead, which is inexpensive and easy to manufacture. However, as lead can be a major factor contributing toward environmental contamination, such poisoning, radiation-shielding plate was in this study tungsten plate, an eco-friendly material, through rolling process at different temperatures. In addition, the shielding produced via h...

We present an image-based algorithm for surface reconstruction of moving garments from multiple calibrated video cameras. Using a color-coded cloth texture, we reliably match circular features between different camera views. As surface model we use an a priori known triangle mesh. By identifying the mesh vertices with texture elements we obtain a coherent parametrization of the surface over tim...

The Readymade Garments (RMG) industry occupies a unique position in the Bangladesh economy. It is the largest exporting industry in Bangladesh, which experienced phenomenal growth during the last 25 years. More than 78 percent of Bangladesh’s export earnings come from the garments industry. The industry plays a key role in employment generation and in the provision of income to the poor. Nearly...
