In this study, selenium was recovered from an industrial dust. After the purification process, the researchers were able to prepare selenium micro powder. The objective of this study was to prepare selenium nano particles by water solution phase method from the micro powders. The results showed that selenium micronized powder and nano particles had high purity. The obtained nanoparticles were t...

The diaphragm is a sheet of muscle that separates the lungs from the abdomen. When a person takes a deep breath, the dome-shaped diaphragm contracts and flattens. In doing this, the diaphragm pulls air into the lungs. The left diaphragm contains a small hole through which passes the tube-shaped esophagus that carries food and liquid to the stomach. Normally this hole, called a hiatus, is small ...

The chick hindbrain starts from a simple and relatively uniform axis and becomes segmented into repeating units, called rhombomeres. The rhombomeres become sites of cell differentiation into specific neurons and the location from which neural crest cells emerge from the neural tube to form the peripheral nervous system, which has only been analyzed at distinct time points due to the lack of a m...

reinke’s Space oedema is characterized by a subepithelial collection of fluid and pseudo-myxomatous tissue within the lamina propria superficialis of the vocal cord. We have observed, in a number of cases, the phenomenon of bilobular and/or centrally located reinke’s Space oedema. Bilobular oedema occurs when the sub-epithelial oedema is organised as a double bulge of the vocal cord in the supe...
