Abstract The application of chemical dispersants aims to stimulate microbial oil degradation by increasing the bioavailability compounds. Overall, nine microcosms were prepared (three for each treatment) using treated sediment with (i) dispersant ( d : 25 ppm), (ii) (500 and (iii) + (500: respectively. There are also three control containing only water without petroleum. Then, we analyzed bacte...

MicroRNAs (miRNAs) are small non-coding RNAs which regulate gene expression by binding to the 3 UTR of the corresponding messenger RNAs. We construct miRNA co-target networks for 22 different species using a target prediction database, MicroCosm Tagets. The miRNA pairs of individual species having one or more common target genes are connected and the number of co-targets are assigned as the wei...

A laboratory based microcosm study was undertaken to determine the persistence of the faecal indicator organism Escherichia coli in coastal recreational water and sediment under varying environmental conditions. Intact sediment cores were taken from three distinct coastal sites in the Adelaide metropolitan area and the overlying water was inoculated with known concentrations of E. coli. The con...

Usually a Riemannian geometry is considered to be the most general geometry, which could be used as a space-time geometry. In fact, any Riemannian geometry is a result of some deformation of the Euclidean geometry. Class of these Riemannian deformations is restricted by a series of unfounded constraints. Eliminating these constraints, one obtains a more wide class of possible space-time geometr...

Decomposition of rice straw residues and the emission CO2, CH4 under paddy crop rotation in Vietnamese Mekong Delta region – A microcosm study | Dung Tran Van, Thu Tat Anh, Long Vu Da Chau Thi Agricultural Journals

A novel artificial microcosm containing all the essential chemical components of soil, but with reduced heterogeneity and biological complexity, has been developed. Its utility for supporting realistic microbial populations was demonstrated and an example of how competing bacteria can be studied is illustrated.

Under an Air Force Phase II SBIR contract, Microcosm is developing a self-configuring avionics network, scheduled for test on a sounding rocket in late 2003 or early 2004. This system is extendable to spacecraft avionics and housekeeping functions, enabling true plug-and-play capability.

The aim of this study was to determine the effect of pulsing chlorhexidine gluconate, at concentrations commonly used in mouthwashes, on Streptococcus sanguis biofilms and microcosm dental plaques in vitro. Biofilms were grown on bovine enamel and nutrients were supplied in the form of artificial saliva. Pulsing experiments were carried out on steady-state biofilms using 0.05 or 0.2% chlorhexid...

Microcosm experiments were performed to understand chemical and biological interactions with hexavalent uranium (U(VI)) in the presence of iron oxide bearing minerals and trichloroethylene (TCE) as a co-contaminant. Interactions of U(VI) and hydrous iron oxide moieties on the mineral oxide surfaces were studied during enrichments for dissimilatory iron reducing (DIRB) and sulfate reducing bacte...
