PURPOSE The validity of clinical perimetry for evaluation of the pathology of glaucoma is based on correlated losses in retinal ganglion cells and visual sensitivity, but procedures to quantify neural losses from visual field defects have not been developed. The purpose of the present study was to investigate the neural and sensitivity losses from experimental glaucoma to establish the framewor...

ball mills are common grinding equipment in mineral processing industries. ball wear results from three mechanisms namely impact, abrasion and corrosion. of these, the corrosion mechanism is the least investigated, due to its chemical-electrochemical nature. therefore, the aims of this research were to investigate the grinding chemistry influence (slurry ph, solid percentage, water chemistry an...

Indigenous mixed populations of anaerobic microorganisms from an irrigation tailwater drain and submerged agricultural chemical waste pit readily biodegraded the major isomer of endosulfan (endosulfan I). Endosulfan I was biodegraded to endosulfan diol, a low toxicity degradation product, in the presence of organic carbon sources under anaerobic, methanogenic conditions. While there was extensi...

Agriculture plays a vital role in the Indian Economy. In India over 70 percent of the rural household depend on agriculture. Insect pests, bacteria, virus, fungi caused plant diseases and weeds inflict enormous losses to the potential agriculture production. Anecdotal evidences also indicate rise in the losses, despite increasing use of chemical pesticides. At the same time, there is a rising p...

Schisandra chinensis (known in Chinese as WuWeiZi, WWZ) has observable effects such as astringing the lung to stop coughs, arresting sweating, preserving semen and preventing diarrhea. The major components of WWZ include lignans, triterpenoids, organic acids and fatty acids. In this paper, a reliable method for the rapid identification of multiple components in WWZ by their characteristic fragm...

Composite manufacturing appears to be one of the most suitable recycling options for chromated copper arsenate (CCA)-treated waste wood. However, in many applications it would be beneficial to remove much or all of the CCA from the wood prior to composite production. This paper evaluates the effect of remediation processes, namely oxalic acid (OA) extraction and Bacillus licheniformis fermentat...

Abstract Oil and gas recovery may cause formation damage during drilling, completion, production phases. As a result of fundamental chemical, thermal, mechanical, biological interactions, can occur due to impairment permeability porosity, causing undesirable operational economic problem. The fluid-rock interactions resulting from oilfield chemicals injection enhanced oil (EOR) such as chemical ...

wheat is one of the most important food staff in consumption pattern of each country. more than 50 percent of energy is provided by bread in the developing countries. the aim of this study was measuring wheat losses during pre-harvest and harvest stages in chaharmahal and bakhtiari province of iran in year 2013. wheat losses at harvest stages were measured to wheat varieties in 2 levels of omid...

Toward the goal of identifying early genetic losses, which mediate the release of human breast epithelium from replicative suppression leading to cellular immortalization, we have used a newly developed in vitro model system. This system consists of epithelial cultures derived from noncancerous breast tissue, treated with the chemical carcinogen N-ethyl-N-nitrosourea, and continuously passaged ...
