gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
Introduction: Photo aging is significantly different from chronological aging in both clinical and histological appearances. It has been suggested that oxidative stress generated by ultraviolet radiation (UVR), leads to photo aging over a long time period. This study was conducted to determine the relationship between the indicators of plasma oxidative stress and photo damaged skin in patient...
comaring the capability of photocatalyst nano zinc oxide process by two slurry and immobilized methods in dye acid orange 7 removal introduction everyday million liters of color wastewater are produced in different industries and cuases environmental problems. the textile industry significantly affects the environment, producing high volume of wastewater from water and chemicals used in process...
this study presents a review on advanced oxidation processes (aop) for simultaneous removal of no and so2. aop is based on using a strong oxidant such as ozone and h2o2 which is able to generate highly reactive intermediates. the pollutant will be oxidized and removed by these intermediates. in recent years, aop has been considered as an effective and attractive technology in the field of flue ...
During recent years, many advanced oxidation techniques have been investigated for water and wastewater treatment to overcome the shortage of clean water. This review summarizes the background and principles of photocatalysis applied as an advanced oxidation technology. In particular, this paper focuses on modification of photocatalysts with various dopants as well as the novel photocatalytic r...
background: the aim of this study was to measure the concentrations (levels) of serum total proteins and advanced oxidation protein products as markers of oxidant mediated protein damage in the sera of patients with oral cancers. methods: the study consisted of the sera analyses of serum total protein and advanced oxidation protein products’ levels in 30 age and sex matched controls, 60 patient...
