lif, mg and ti cubical tld chips (known as tld-100) are widely used for dosimetry purposes. the repeatability of tl dosimetry is investigated by exposing them to doses of (81, 162 and 40.5 mgy) with 662kev photons of cs-137. a group of 40 cubical tld chips was randomly selected from a batch and the values of element correction coefficient (ecc) were obtained 4 times by irradiating them to doses...

By employing metastable impact electron spectroscopy (MIES) and ultraviolet photoelectron spectroscopy (UPS) together with work-function measurements, three adsorption states of benzene have been identified on the clean Mo(100) surface at 100 K: a chemisorbed layer, a second physisorbed layer with the aromatic rings plane parallel to the surface, and at higher coverages, an adsorbed layer with ...

Vitiligo is an autoimmune skin disease which is characterized by depigmented patches due to loss of pigment cells. Evidence suggests that cell-mediated immunity plays a role in melanocyte destruction while some patients have antibodies to melanocytes or melanocytic proteins. Vitiligo is strongly associated with a number of autoimmune disorders. Autoimmune thyroiditis is the most prevalent disea...

in this study canthaxanthin was produced by dietzia natronolimnaea hs1 and used for incorporation in niosomes after extraction. effect of rotational speed of rotary vacuum evaporator flask (100 and 150 rpm), canthaxanthin concentration (0, 1 and 2 microgram/ milliliter), concentration of poly ethylene glycol 400 (0, 0.1 and 0.2 %), surfactant type (tween 60 and 80, span 60 and 80) and surfactan...
