OBJECTIVES Effect of paraquat on the fatty acid composition (weight percentage) of rat lung was studied with particular reference to the change of hydroxyproline content in the course of paraquat-induced dysfunction and subsequent repair. METHODS Eight-week-old male Wistar rats were administered paraquat at 20 mg/kg body weight subcutaneously, and the wet weight, hydroxyproline content and fa...

This paper describes research into concentration of total proteins and individual protein fractions in the blood serum of Ross broiler chickens during fattening period. Blood for analysis was taken at the 14th, 28th and 42nd days of age by wing vein puncture. Concentration of total serum proteins was detected by spectrophotometry. Electrophoresis on gelled cellulose-acetate tapes determined the...

An approach to target-based image retrieval is described based on on-line rank-based learning. User feedback obtained via interaction with 2D image layouts provides qualitative constraints that are used to adapt distance metrics for retrieval. The user can change the query during a search session in order to speed up the retrieval process. An empirical comparison of online learning methods incl...
