objective cerebrospinal fluid (csf), its secretion, circulation and absorption have been the subject of recent researches. there is a general agreement that the main site of csf secretion is in the choroids plexus. however, the main absorption site is controversial. some believe that arachnoid granulations are the principle sites of csf absorption. in this study, different locations of csf abso...

steel slags are the by products of steel industries, which forms during reduction process of iron melting. the chemical composition of it changes depending to the melting procedure. its mineralogical composition also varies based on the cooling procedure. two different types of steel slag were used as absorbing bed for various concentrations of pb2+ ions in the form of lead chloride, and the co...

i ntroduction: liposuction using laser is now one of the most common cosmetic surgery. this new method has minimized the disadvantages of the conventional liposuction including blood loss, skin laxity and long recovery time. benefits of the new liposuction methods which include less trauma, bleeding and skin tightening prove the superiority of these methods over the traditional mechanical metho...

background: nickel is an important constituents widely used in different industrial processes for production of various syn¬thetic materials. for evaluation of workers’ exposure to trace toxic metal of ni (ii), environmental and biological monitor¬ing are essential processes, in which, preparation of samples is one of the most time-consuming and error-prone as¬pects prior to analysis. methods: ...

Currently, the performances of thin film solar cells are limited by poor light absorption and carrier collection. In this research, large, broadband, and polarization-insensitive light absorption enhancement was realized via integrating with unique metallic nanogratings. Through simulation, three possible mechanisms were identified to be responsible for such an enormous enhancement. A test for ...

The plasma cortisol levels of 17 infants of mean age 12.1 months taken at 8 AM were measured before and after application of a topical fluorinated glucocorticosteroid. There was a statistically significant depression of plasma cortisol value in 11 infants at days 3, 7, and 14 after therapy. All of the plasma cortisol levels returned to normal. For the entire group of 17 infants, however, there ...

A pre-strained polystyrene (PS) polymer sheet is deformed when it approaches the glass transition state as a result of light absorption. By controlling the light absorption of the polymer sheet, non-contact sequential folding can be accomplished. Line patterns of different transparencies and shapes are used to control the light absorption. The line pattern shape is closely related to the foldin...

It is believed that rare earth elements are not absorbed, and thus they are generally used in some mineral absorption studies as a faecal marker. The aim of the present study was to determine the effect of inulin intake and age on dysprosium (Dy) absorption in rats. Eighty male Wistar rats of four different ages (2, 5, 10 and 20 months) were randomised into either a control group or a group rec...
