1,2-Dichloroethane (1,2-DCA) and 1,2-dibromoethane (ethylene dibromide [EDB]) contaminate groundwater at many hazardous waste sites. The objectives of this study were to measure yields, maximum specific growth rates (μ), and half-saturation coefficients (K(S)) in enrichment cultures that use 1,2-DCA and EDB as terminal electron acceptors and lactate as the electron donor and to evaluate if the ...

An analytical model is used to simulate the effects of partial source removal and plume remediation on ethylene dibromide (EDB) and 1,2-dichloroethane (1,2-DCA) plumes at contaminated underground storage tank (UST) sites. The risk posed by EDB, 1,2-DCA, and commingled gasoline hydrocarbons varies throughout the plume over time. Dissolution from the light nonaqueous phase liquid (LNAPL) determin...

Six unsymmetrical diorganyltellurium(IV) dichlorides RR'TeCl2 (where R= phenacyl-, 1-naphthacyl-, and styrylacyl- and R' = p-methoxyphenyl, p-hydroxyphenyl-, and 3-methyl-4-hydoxyphenyl-) were tested for their antibacterial activity against gram-positive (Bacillus subtilis ATCC 6633 and Staphylococcus aureus ATCC 25923) and gram-negative (Escherichia coli ATCC 25922. Pseudomonas aeruginosa ATCC...

Creativity is an important factor in collaborative activities such as design. Many researchers have developed design tools and environments to support the design process and creativity within the design process. However, with a few exceptions, the understanding and support of creativity has received little attention in the design community. Even in the exceptions, there has been little reported...

Respected on both sides of the Atlantic for questioning the tenets underlying the pathophysiology of diabetes and its complications, Trevor Orchard continues to influence the fields of epidemiology and medicine. With a self-effacing style that might be described as typically British, he remains provocative and prominent among the research community. An Englishman educated in Wales and living in...

The title compound, [Zn(H(2)O)(6)]Cl(2)·2C(6)H(12)N(4)·4H(2)O, has been prepared under mild hydro-thermal conditions. The Zn(II) atom, located on a centre of symmetry, is coordinated by six water mol-ecules in a distorted octa-hedral coordination geometry. The hexa-methyl-enetetra-mine mol-ecule is not coordinated to Zn(II) but links the Zn complexes via three O-H⋯N hydrogen bonds. The remainin...

Micrococcus luteus strain NDB3Y10, which utilizes 1,2-dichloroethane as a carbon source, was isolated from a bore well that produces coal seam gas. The draft genome size of the strain was 2.49 Mb with a G+C content of 72.97%. Genes involved in the metabolism of halogenated substrates, including halogenated hydrocarbons, were identified.

reaction may be more readily standardized because the time ofheating is not so critical as in the method of Thomas. Further, the time of heating is sufficiently long to allow equilibration between the boiling-water bath and the content ofthe test tubes, so that differences in wall thickness are not important. It is also unnecessary, since the colour is stable, to take readings within 8 min. of ...

In the title compound, C(14)H(30)N(2) (2+)·2Cl(-), the N,N'-dicyclo-hexyl-ethyl-enediammonium cation posseses crystallographic symmetry, and thus the compound crystallizes with two formula units per unit cell. In the crystal, the cations and anions are linked by N-H⋯Cl hydrogen bonds, giving a two-dimensional network with {6,3} topology.

Note: The following text was prepared in response to the present discussion regarding the European Commission’s recommendations on the so called ‘‘endocrine disrupting chemicals’’ and is supported by the editors and associate editors of Toxicology in Vitro, Bas Blaauboer, Frank Barile, Daniel Acosta Jr, Billy Day and Kerstin Stemmer. It also refers to a letter sent in response to these recommen...
