A recent proposal that leatherworkers might face a reproductive hazard was tested using data from a large survey in Montreal of occupational factors in pregnancy. The outcome ofpregnancy in almost 400 women employed in the manufacture of leather products, some 6000 employed in other types of manufacture, and nearly 50 000 employed but not in manufacture were compared. There was little differenc...

Release of leather industry effluents into the agricultural fields causes indicative changes in nutrient cycling and organic matter processing. In the present study, leather industry effluent discharged soil (test) and undischarged soil(control) were collected from the surrounding areas of industry. The physico-chemical, biological properties and soil protease activity were examined. The study ...

Archaeological studies have shown that hides and skins have been used since antiquity as clothes, vessels, bedding, and possibly structurally in ancient dwelling places. At present, leather is used in various applications. Hides and skins, raw materials for the tanning industry, are renewable and easily perishable resources (Arugna, 1995). Their production is dependent on the rearing, managemen...

The performance of Support Vector Machines, as many other machine learning algorithms, is very sensitive to parameter tuning, mainly in real world problems. In this paper, two well known and widely used SVM implementations, Weka SMO and LIBSVM, were compared using Simulated Annealing as a parameter tuner. This approach increased significantly the classification accuracy over the Weka SMO and LI...

Conductive leather and its use in smart products have found a lot of interest. Leather behaves as good insulator, so it was treated with electrically conducting polypyrrole using chemical polymerization technique to give conductive characteristics. The electro-conductive properties are obtained by the double in–situ oxidative pyrrole. electrical samples studied Van Der Pauw method measuring met...

Toxic odour causes pollution to environment. Removal of odour from wet processing sections of leather tanneries is important to preserve safety and occupational health. Such odour causing gases are identified in nature and are identified mostly as ammonia, Hydrogen sulfide and Volatile organic compounds. These gases, evolving from tanning drums, were experimentally quantified and analysed. Tech...

the study was consequently investigated effect of different tanning methods on apparent density, thickness, tensile strength and also extension percentage in three different tanning (chromic, alum and vegetable) of grown part of ostrich skins (n = 15; 12 to 14 months). average apparent density and thickness of leathers were 0.7 ± 0.0gr/cm2 and 1.7 ± 0.1 mm, respectively. the breaking load, tens...

Cow leather is a widely used material. Even though durable, it causes ethical, social, and environmental issues. The synthesis of vegan leather, using symbiotic culture bacteria yeast (SCOBY), could be explored for an alternative to cow leather. Presently, there are limited studies on the different substrates produce this method. Hence, study aimed plant-based various such as black tea, green c...
