One of the operating costs of exploiting underground mines is related to ventilation operations.The development of the underground network during the mine life and new excavations will cause a redesign of the ventilation plan over and over again.Excavating the waste pass in the Anguran underground lead and zinc natio glide on eyeshadow stick mine a
This paper undertakes a review of the literature that examines the highlights and changes in specific external environmental factors (Ecology, Economy, Politics, Legislation and legal structures, and Society), between1994 and 2008 in South Africa, with the aim to ascertain how these factors affect the day-to-day labour relations in the workplace an
The present study aims to evaluate the reverse flotation performance of iron ore, using collector (amine), in the presence and absence of chain extender (diesel oil) and emulsifier (sodium lauryl sulfate).Six tests were realized with duplicate.Tests using peperomia double duty amine, diesel oil and sodium lauryl sulphate show the better results, wi
In this study, hydrangea red sensation two strains of Aspergillus sp.and Lysinibacillus sp.with remarkable abilities to degrade low-density polyethylene (LDPE) were isolated from landfill soils in Tehran using enrichment culture and screening procedures.The biodegradation process was performed for 126 days in soil using UV- and non-UV-irradiated pu
Mislocalised membrane proteins (MLPs) present a risk to the cell due to exposed hydrophobic amino acids which cause MLPs to aggregate.Previous studies identified SGTA as a key component of here the machinery that regulates the quality control of MLPs.Overexpression of SGTA promotes deubiqutination of MLPs resulting in their accumulation in cytosoli
