this paper deals with an inspection of defects including corrosion and leakage by acoustic emission (ae) in an oil tank floor. in contrast to intrusive methods such as magnetic flux leakage, eddy current or ultrasonic, there is no need to emptying and entering the tank in ae method in order to inspection. in this research ae investigation and ae source location is presented in detail. the resul...

Zymograms of the aspartate aminotransferase (AAT, EC 2.6.1.1) activity in leaf extracts from Aegilops and Triticum species revealed three AAT zones, denoted according to the decreasing electrophoretic mobility towards the anode as AAT-1, AAT-2 and AAT-3. The AAT activity zymograms of subcellular fractions isolated from T. aestivum seedlings made it possible to establish that the AAT-1 zone is l...

biological research of all kinds on mosquitoes must be built upon a foundation of correct identification and sound classification. except for the anopheline vectors of malaria, relatively little is known about other mosquitoes in iran and other countries in southwest asia. in view of this a comprehensive study on the mosquito fauna of iran has started since 1981. in this report the list of the ...

Carum carvi (CC) is a grassy plant which is believed to have several therapeutic effects, including anti-asthmatic properties. We have therefore studied the bronchodilatory and anticholinergic effects of this plant. The bronchodilatory effects of the aqueous extract (AE), macerated extract (ME), essential oil (EO), and 4µM theophylline (T) in comparison with saline (S) were examined by the...
