Background: Artichoke extract (AE), containing natural antioxidant compounds, can be considered as a good source of antioxidant potential. OBJECTIVES: The aim of this study was to evaluate antioxidant abilities of AE on broiler meat quality. METHODS: 200 Ross chicken broilers were divided into five equal groups and received 100, 200, 300, and 500 mg/liter of AE in drinking water and pure water ...

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...

The objective of present study is to determine seasonal changes in biochemical content freshwater bivalve, Parreysia cylindrica relation heavy metal pollution Jayakwadi reservoir. Heavy concentrations were determined seasonally from surface water, soil sediment and soft body tissues cylindrica. highest during summer season than winter monsoon season. Protein, DNA, RNA Ascorbic acid estimated su...

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 ...

The cyanobacteria Anabaena cylindrica and Synechococcus leopoliensis (= Anacystis nidulans) were grown at different levels of UV-B radiation (439, 717, 1230 and 1405 J m “2d_ l, weighted according Caldwell. 1971) for 2 days. Dry weight was hardly affected but phycocyanin content of both species decreased linearly to the level o f UV -B radiation.

Environmental conditions in coastal salt marsh habitats have led to the development of specialist genetic adaptations. We evaluated six DNA barcode loci of the 53 species of Poaceae and 15 species of Chenopodiaceae from China's coastal salt marsh area and inland area. Our results indicate that the optimum DNA barcode was ITS for coastal salt-tolerant Poaceae and matK for the Chenopodiaceae. Sam...

Biological mediation of carbonate dissolution represents a fundamental component of the destructive forces acting on coral reef ecosystems. Whereas ocean acidification can increase dissolution of carbonate substrates, the combined impact of ocean acidification and warming on the microbioerosion of coral skeletons remains unknown. Here, we exposed skeletons of the reef-building corals, Porites c...

The weathering of volcanic rocks contributes significantly to the global silicate weathering budget, effecting carbon dioxide drawdown and long-term climate control. The rate of chemical weathering is influenced by the composition of the rock. Rock-dwelling micro-organisms are known to play a role in changing the rate of weathering reactions; however, the influence of rock composition on bio-we...
