purpose: to evaluate the effect of fullerene on chemical properties of naphazoline drug in water by density functional theory (dft) methods. materials and methods: naphazoline belongs to the imidazoline class of sympathomimetics. the present study on naphazoline drug and its fullerene connected form were carried out using computerized calculations of gaussian program in b3lyp/6-31g leve...
this study examined the effects of collaborative strategic reading and direct instruction in persuasion on iranian high school students persuasive writing and attitudes. students in three intact classes were assigned to one of three treatment conditions: collaborative strategic reading and direct instruction in persuasion or direct instruction in persuasion or a control group. treatment effects...
The study was to evaluate the neurobehavioural and cognitive changes in Wistar rats administered carbamazepine (CBZ), phenytoin (PHE) and their combination. Forty, apparently, healthy adult male Wistar rats weighing about 300 g were divided into four groups of 10 animals each. Group I rats were administered distilled water at 10 ml/kg. CBZ, 20 mg/kg, PHE 100 mg/kg and CBZ+PHE, 20 mg/kg and 100 ...
Caspian Sea is the largest land locked water body in the world and has been characterized by significant relative sea-level changes since the Pliocene. The sea-level oscillations have strongly impacted the coastal areas depending on geomorphological setting. This study aims to investigate the impacts of sea level oscillations on low-lying coasts of the southeastern flank of the Caspian Sea...

Groundwater resources are considered as a largest reservoir of available freshwater in the world. According to the importance and scarcity of this precious resource, studying the groundwater quality changes is very important. Declines in water level of Urmia lake has led to increase in the salinity of water in this lake. In this paper, water level reduction effects were studied on qualitative c...
This study aimed to investigate the effects of different alkalinity levels on growth performance, carcass analysis and blood parameters of kutum fingerlings. The examined fish samples were reared in five levels of alkalinity including a Hall water (control) with an alkalinity of 250 mg/l, 50% distilled water+50% Hall water (110 mg/l alkalinity), Hall water + 10 g sodium bicarbonate (soda, 350 m...
