Since the time of the first microbe hunters, primary culture and isolation of bacteria has been a foundation of microbiology. Like other microbial methods, bacterial culture and isolation methodologies continue to develop. Although fundamental concepts like selection and enrichment are as relevant today as they were over 100 yr ago, advances in chemistry, molecular biology and bacterial ecology...

Whether transmission of the chronic wasting disease (CWD) prion among cervids requires direct interaction with infected animals has been unclear. We report that CWD can be transmitted to susceptible animals indirectly, from environments contaminated by excreta or decomposed carcasses. Under experimental conditions, mule deer (Odocoileus hemionus) became infected in two of three paddocks contain...

We present the Environmental Scenario Search Engine (ESSE), a set of algorithms and software tools for distributed querying and mining large environmental data archives. The principal requirement of the ESSE system is to allow the user to query the data in meaningful “human linguistic” terms. The mapping between human language and computer systems involves fuzzy logic. We use a data resource we...

Aeromonas spp. are ubiquitous aquatic bacteria that cause serious infections in both poikilothermic and endothermic animals, including humans. Clinical isolates have shown an increasing incidence of antibiotic and antimicrobial drug resistance since the widespread use of antibiotics began. A total of 282 Aeromonas pure cultures were isolated from both urban and rural playa lakes in the vicinity...

Decisions in the environmental and in particular the climate domain are burdened with uncertainty. Here, we focus on uncertainties faced by individuals when making decisions about environmental behavior, and we use the statistical sampling framework to develop a classification of different sources of uncertainty they encounter. We then map these sources to different public policy strategies aim...

The present study investigates how chief executive officers in the Canadian telecommunications industry acquire and use information about the external business environment, an information seeking activity known as environmental scanning. Data were collected by a nationwide questionnaire survey and several focused interviews. Of the 113 CEOs in the study population, 67 returned completed questio...

in recent decades, due to increasing prices of fossil fuels and environmental pollution resulting from the increased energy demand, researches on renewable energy sources have attracted lots of researcher’s attention. limited investing sources and environmental issues are important factors effecting electricity generation sector. minimizing costs and environmental damages are issues being consi...

Energy is the fundamental source for the human being to implement the current and oncoming all of the technological, industrial, communicational activities. In other words energy is an indispensable requirement fort he current modern information community and energy will continue to be one of the most important sources in the future. Energy requirement rises day by day; furthermore available so...
