Spleen development was studied in 11 groups of chicken embryos: (1) intact, /; (2) 'hypophysectomized', H, by partial decapitation, and nine groups of' hypophysectomized' embryos in which each host received a specific type of pars distalis graft; (3) one cephalic region, HCe; (4) one middle region, HM; (5) one caudal region, HCa; (6) the entire pars distalis, HE; (7) two cephalic regions, H2Ce;...
Background and aims: Safety in companies related to oil and gas is very important. Hence, the purpose of current study is to assess safety culture by using behavioural and environmental forms in staffs of South Pars Gas Company. Methods: Totally, 1000 participants were randomly selected for this descriptive study from different parts of South Pars Gas Company. After selection of participants...
As little is known about the neurotoxicity of histological structure brain, this study focuses on side four- to six-month-old adult Wistar rat brains, which were examined after 0.1 mg\g organophosphate had been administered orally. In study, lesions mainly localized at hippocampus and substantia nigra (compacta pars) region. Distinct areas necrotic apoptotic tissues detected in CA1, CA2, dentat...
X-band dual-polarization phased-array weather radars (X-PARs) have been used in South China extensively. Eliminating the attenuation and system bias of radar data is key to utilizing advantage X-PAR networks. In this paper, disdrometer raindrop-size distribution (DSD) measurements are calculate polarimetric variables analyze characteristics precipitation attenuation. Furthermore, based on netwo...
The toxicity of heavy metals in sediments of the Nayband Bay and Asaluyeh region and potential ecological risk to sediment organisms assessed. Three stations with different degrees of vulnerability of South Pars Oil and Gas Activities (1: Control - 2: medium affected and 3: severely affected) were selected in the study area. Sediment sampling at each station in both cold and hot seasons (2010) ...
In the Persian Gulf region, conditions are highly favorable for ozone air pollution and the region is a hot spot of photochemical smog. The vast activities in processing oil and gas play a major role in it. It was found that the elevated concentrations of reactive hydrocarbons co-emitted with nitrogen oxides from Hydrocarbon Processing facilities lead to substantial ozone production. South Pars...
Hydrocarbon Processing Industries (HPIs) emit large amounts of highly reactive hydrocarbons and Nitrogen Oxides to the atmosphere. Such simultaneous emissions of ozone precursors result in rapid and high yields ozone (O3) formation downwind. The climate of the Middle East has been shown to be favorable for O3 formation in summer. There are also vast activities in processing oil and gas in this ...
The micropyle number in the ova of sturgeon species from the South Caspian Sea was investigated. The study was conducted on female broodfishes of three species of sturgeon (Persian sturgeon Acipenser persicus, Stetates sturgeon A. stellatus and great sturgeon Huso huso) included 44 Persian sturgeon, 13 stellate sturgeon and 8 great sturgeon specimens. Fifty eggs were randomly collected from eac...
Background and Objective: Hydrocarbon processing industries are considered as potential sources of volatile organic compounds (VOCs) due to their specific nature. These compounds can directly or indirectly through producing secondary pollutants have adverse effects on the health of individuals. Therefore, identification of them is an important step in the formulation of control programs. This s...
