in this study, oxic and anoxic microcosms were constructed with aquifer sediment collected from the vicinity of a municipal solid waste composting site.phenanthrene was used as a model pah compound. the changes of bacterial and archaeal communities in microcosms were characterized with terminal restriction fragment length polymorphism. 16s rrna gene clone library analysis was also used to inves...

Campylobacter jejuni is a pathogenic, microaerophilic, gram-negative, mesophilic bacterium. Three strains isolated from humans with enteric campylobacteriosis were able to survive at high population levels (10(7) cells ml-1) as viable-but-nonculturable (VBNC) forms in microcosm water. The VBNC forms of the three C. jejuni strains were enumerated and characterized by using 5-cyano-2,3-ditolyl te...

This paper describes the design and implementation of a new, direct communication model for the Microcosm open hypermedia system. Both the current and new communication models are described in detail, along with the major differences between the two, and how those differences will affect the overall performance of the system. In addition, it describes the effect that the new model will have on ...

There are currently a number of commercially available hypertext and hypermedia systems, of varying levels of sophistication and usability, but there are still many problems to be resolved in the design of such systems. In this paper, we itemise some of the major problems that we have identi®ed as possibly causing a barrier to the growth and development of hypermedia applications outside the re...

In the so-called real world, any given process occurs simultaneously with a myriad of other processes. All these processes take place on a continuum of mass, energy and time (the world). All things in this continuum are interlinked in some way. Defining a process as such is in itself already an act of abstraction. One way to study a process is to split it into three entities: the observer, the ...

Kerosene is the colorless liquid and slightly heavier than gasoline thatspecific odor removes after evaporation. Soil and underground water source arecontaminated with different pollutants such as petroleum hydrocarbons. These pollutantshave various negative environmental effects on soil and surrounding environment. Theaim of this research is to understand the effect of kerosene pollution on tw...
