The objective of this work was to investigate vacuum influence on hide preservation time and how it affects hide structure. It was established that vacuum prolongs the storage time without hide tissue putrefaction up to 21 days when the storage temperature is 4°C. The microorganisms act for all storage times, but the action is weak and has no observable influence on the quality of hide during t...

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 goal of this research is preparation, optimization and in-vitro evaluation of rifampin-loaded silica nanaoparticles in order to use in pulmonary drug delivery. nanoparticles are exhaled because of thier small size, preparation of nanoaggregates in micron-sized scale and re-disrpersion of them after the deposition in the lung is one approach in order to overcome this problem, which we used i...

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...

in this work, leather fibers were employed as a component of elastomeric compounds based on nbr, cr and epdm and studied were made on their effects upon curing characteristics and mechanical properties of the prepared compounds. evaluation of curing characteristics of the compounds demonstrated that leather fibers have no considerable effect on initial viscosity and curing time of the compounds...

Fruit leathers, which are also known as fruit rolls, dehydrated fruit-based products. Despite the popularity of Lapsi leather, its production is limited to home-scale industries, lack uniformity in quality. Moreover, scientific research address this issue very limited. Therefore, study, leather was prepared and nutritional, phytochemicals, sensorial properties were studied. The pulp sugar mixed...

In this study, Cynara scolymus L. leaves aqueous extract powder was produced using a novel spray drying approach by incorporation of ongoing ultrasonic atomization and vacuumed drying chamber. A Response Surface Methodology (RSM)-based central composite face-centered design was employed for optimization of the operating conditions of the ultrasonic vacuum spray dryer. The independent variab...

The main purpose of this work is to optimize the biomass drying and carbonization process in terms of both proximate analysis and biomass calorific value, simultaneously. The biomass material used in the study is coconut shells. The independent variables are the drying temperature, the drying time, the carbonization temperature and the carbonization holding time. The dependent variables are pro...

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...
