Background: Large amount of solid waste is annually produced in Kuhdasht city. These waste materials are decomposed by anaerobic microorganisms after burying in disposal site and produce large amounts of gases (mainly methane and carbon dioxide). This study aimed to estimate the gas emission from solid waste disposal of Kuhdasht city using a tool known as LandGEM software. Materials and Method...
A computer program was developed to predict the dispersion of gas pollutant in the atmosphere. This program relies on puff method, and in order to consider the wind shear effects, the program has the ability to consider the complete dynamic and unsteady atmospheric conditions. Plume rise of hot pollutants due to buoyancy effects was also considered. The program has the capacity to perform the r...
Radon and Thoron are the radioisotopes which radiate high alpha energy particles. These two gases can enter in the body by different ways such as inhalation, eating and drinking and then destroy body`s internal tissues and cause the lung cancer. The condensation of these gases differs in various areas and is more in zones near active faults. In this research, first the relation of Radon and Tho...
Background and purpose : Arterial blood gases ( Arterial blood gas [ABG] ) One of the most important Laboratory tests to determine the status PH the amount of oxygen and carbon dioxide blood levels of bicarbonate. Also, hemoglobin and serum lactate and electrolytes and also won the Test . Height and air pressure can vary on ABG and its surface, low pressure conditions at high altitude pilots pl...
odor emission is a common environmental problem in septic tank. the feasibility of using trickling filter to eliminate the malodorous gases from the septic tank was studied. a trickling filter is set up at the outlet of the waste gases of the septic tank, which was attached to the university's cafeteria. in this investigation, the trickling filter system was used, measuring the hydrogen sulfide...
the objective of this study was to find a relationship between blood gas parameters and thyroid hormoneactivity with ascites syndrome in broiler chickens exposed to cold temperature and receiving a high qualitydiet. one hundred and sixty one-day-old broiler chicks were randomly divided in two equal groups. toincrease the incidence of ascites, chicks of group 1 were fed ad libitum with a higher ...
Tropospheric ozone, lot-med from nonlinear reactions between VOC5 and nitrogen oxides (NOr), is a primarr constituent of urban smog (1). Estimates of VOC control costs needed to attain the National Ambient Air Quality Standard (NAAQS) for ozone of 0.12 parts per million are on the order of billions of dollars per year, and in the most severely impacted region~, the necessary control technologie...
