Corn syrup films are used to replicate holograms in order to fabricate micro-structural patterns without the toxins commonly found in photosensitive salts and dyes. We use amplitude and relief masks with lithographic techniques and rubbing techniques in order to transfer holographic information to corn syrup material. Holographic diffraction patterns from holographic gratings and computer Fouri...

Lichen sclerosus (LS) is a chronic benign inflammatory disorder of skin and mucosa which affects patients of all age groups, sex and race, particularly caucasian prepubertal girls and postmenopausal women. The etiology of LS is unknown, but it has been suggested that genetic predisposition to inflammatory disorders, immunological constitutions, hormonal influences and local factors might play a...

Affiliative contact behaviors such as grooming and socio-sexual behavior play an important role in the expression and negotiation of social bonds. In rare cases an affiliative contact behavior may be restricted largely to one sex. P...

Friction coefficient and wear rate of different steel materials are investigated and compared in this study. In order to do so, a pin on disc apparatus is designed and fabricated. Experiments are carried out when different types of disc materials such as stainless steel 314 (SS 314), stainless steel 202 (SS 202) and mild steel slide against stainless steel 314 (SS 314) pin. Experiments are cond...

This study evaluated the color fastness and crust quality of eco-printed leather using various types mordant in natural dye mangrove extract. used 20 sheepskin crusts bark experimental employed a Completely Randomized Design (CRD) with different as treatments. The were Aluminum Sulfate (Al2(SO4)3), Calcium Carbonate (CaCO3), Citric Acid (C6H8O7), Ferrous (FeSO4). results showed that use (FeSO4)...
