BACKGROUND Chromium (Cr) release from Cr-tanned leather articles is a major cause of Cr contact dermatitis. It has been suggested that Cr(VI) release from leather is not necessarily an intrinsic property of the leather, but is strongly dependent on environmental conditions. OBJECTIVES To test this hypothesis for long-term (8 months) simulated use. MATERIALS AND METHODS The release of total ...

Little is known about the factors affecting leather and skin traits in ostriches. The effect of age on physical skin traits of slaughter ostriches was consequently investigated. Forty skins representing slaughter ages ranging from five to 14 months were selected to represent means of the respective age groups with regard to skin size and slaughter weight. It was evident that leather thickness i...

This study attempts to understand the socio-economic conditions and working condition of leather tannery workers. The leather tanning industry and leather related industry give employment and business opportunities for many people. The rising cost of living compels the tannery workers to take up the job. The tannery workers are exposed to lot of chemicals for low wages. But this leads to health...

The interest in the carcinogenic and biological actions of N-nitroso compounds arose following the reports of the hepatotoxicity by Freund' and Barnes and Magee2 and ofcarcinogenicity (Magee and Barnes)3 of the simplest nitrosamine: N-nitrosodimethylamine (dimethylnitrosamine) and the subsequent observation of Schoental4 and Druckrey et aP on the carcinogenic action of the nitrosamides: n-methy...

Abstract Aerogels are predominantly mesoporous, extremely lightweight, low density (∼ 0.003 g/cm 3 ) and thermally insulating materials. Over the years, aerogels have gained increasing attention due to their extraordinary properties (light, heat, sound, electricity force) application potentials in varieties of fields. Several studies been carried out regarding aerogel preparation its applicatio...

Twelve ruminally cannulated steers (Angus x Holstein; average initial BW = 533 +/- 3.28 kg) were randomly allotted to one of three treatments (four steers/treatment) to evaluate the use of pretanned leather shavings as a component of a protein supplement for steers grazing dormant intermediate wheatgrass (Thinopyrum intermedium Host). Steers were allotted to one of three treatments: 1) no suppl...

in the present work the magnitudes of pigments in the synthetic leather, were measured by means of scanner. initially synthetic leather samples pigmented by three different pigments of yellow, blue and red colors were prepared. then the pigmented samples were scanned, and the values of rgb of images were calculated. the artificial neural network (ann) method used to make relation between rgb va...
