Background: Erysipelothrix rhusiopathiae (E. rhusiopathiae) is generally transmitted into the gastrointestinal tract of animals by the intake of contaminated food or water and causes great economic loss in agriculture worldwide. Some of the Erysipelothrix spp. are the causative agents of erysipeloid, which is an occupational infection in humans. The aim of the present study was to isolate E. rh...

In this paper, we study an identification method for use in e-Test systems. The e-Test is a tool for assessing knowledge of examinees over the World Wide Web. This type of test is useful for examinees at distant locations. However, some drawbacks of the e-Test have been pointed out, especially when used for strict tests such as the entrance examination tests of universities. One of the most cri...

there is a great interest in developing rapid analytical methods and provide appropriate parametersfor quantitative analysis of compounds derived from refractory pollutants. such methods are important forroutine quality control analysis of an effluent before being discharged into the environment. therefore, a rapid methodology for identification and quantification of some aliphatic acids is pro...

Eremostachys pulvinaris (family: Labiatae), one of the 60 species of the genus Eremostachys, occurs mainly in central Asian countries, e.g. Iran, Armenia, Ashgabad and the USSR. The rhizomes of this plant were collected from Tabriz in Azarbaijan province during September-October 2003. There is no report on any previous phytochemical investigation on E. pulvinaris available todate, phytochemical...

BACKGROUND Isolates of the Enterobacter cloacae complex have been increasingly isolated as nosocomial pathogens, but phenotypic identification of the E. cloacae complex is unreliable and irreproducible. Identification of species based on currently available genotyping tools is already superior to phenotypic identification, but the taxonomy of isolates belonging to this complex is cumbersome. ...

Risk identification consists of defining the hazard, losscausing event E, probability P(E) of that event, perception Pe(E,P(E)) and consequences C(Pe) of that perception. Risk identification is followed by risk management, whose purpose is to mitigate the risks, for example by reducing P(E) or C(Pe) and providing suitable risk communication to the population at risk. Since managing risk has a f...

Dogs can be infected by several nematodes of the Trichuridae family. Trichuridae eggs are all similar, barrel shaped with polar plugs, and misdiagnosis among different species can occur. The most common species is Trichuris vulpis, while the respiratory parasites Eucoleus boehmi (syn. Capillaria boehmi) and Eucoleus aerophilus (syn. Capillaria aerophila) are rarely observed in pets. E. boehmi i...

Person re-identification methods seek robust person matching through combining feature types. Often, these features are assigned implicitly with a single vector of global weights, which are assumed to be universally and equally good for matching all individuals, independent to their different appearances. In this study, we present a comprehensive comparison and evaluation of up-to-date imagery ...
