To manage risk or to implement natural attenuation as a remedy, regulatory agencies must understand the processes that attenuate methyl-tert-butyl ether (MTBE) in ground water. Most case studies and laboratory studies in the literature indicate that natural biodegradation is not important; however, recent reports indicate that natural biodegradation of MTBE plays an important role under certain...

Methyl tert-butyl ether ~MTBE! contamination in groundwater often coexists with benzene, toluene, ethylbenzene, and xylene ~BTEX! near the source of the plume. Tertiary butyl alcohol ~TBA! is a prevalent intermediate of MTBE degradation. Therefore, there is a significant potential for interference of MTBE and TBA degradation by the presence of BTEX whether treatment is in situ or ex situ. In th...

A methyl tert-butyl ether (MTBE) / tert-butyl alcohol (TBA) plume originating from a gasoline spill in late 1994 at Vandenberg Air Force Base (VAFB) persisted for over 15 years within 200 feet of the original spill source. The plume persisted until 2010 despite excavation of the tanks and piping within months after the spill and excavations of additional contaminated sediments from the source a...

In the present paper a new potentiometric biosensor for terbuthylazine (TBA, a herbicide widely utilized in agriculture) suitable for this determination in water samples is shown. As previously described, monoclonal antibody (mAb) showing high specificity for the analyte was utilized as biological element to perform the biosensor assay. A light addressable potentiometric sensor (LAPS), measurin...

The Task-Based Approach (TBA) has gained popularity in the field of language teaching since the last decade of the 20fh Century and significant scholars have joined the discussion and increased the amount of analytical studies on the issue. Nevertheless experimental research is poor, and the tendency of some of the scholars is nowadays shifting towards a more tempered and moderate stand on thei...

Dimerisation of isobutene produces diisobutenes that can be hydrogenated to isooctane (2,2,4-trimethyl pentane). Isooctane can be used as a high octane gasoline component. The aim of this work was to study the selective production of diisobutenes through the dimerisation of isobutene on ion-exchange resin catalysts and to construct kinetic models for the reactions in the system for reactor desi...

The adsorption and the redox behaviour of thrombine binding aptamer (TBA) and extended TBA (eTBA) were studied using atomic force microscopy and voltammetry at highly oriented pyrolytic graphite and glassy carbon. The different adsorption patterns and degree of surface coverage were correlated with the sequence base composition, presence/absence of K and voltammetric behaviour of TBA and eTBA. ...

The adsorption and the redox behaviour of thrombin-binding aptamer (TBA) and extended TBA (eTBA) were studied using atomic force microscopy and voltammetry at highly oriented pyrolytic graphite and glassy carbon. The different adsorption patterns and degree of surface coverage were correlated with the sequence base composition, presence/absence of K(+), and voltammetric behaviour of TBA and eTB...

A novel ultrasensitive biosensor was constructed by the [TBA]2[Ni(mnt)2]/graphene (mnt = maleonitriledithiolate) composite film for the detections of glutamate and alanine aminotransferase (ALT). The [TBA]2[Ni(mnt)2] nanocubes with a dimension of 500 nm were in-situ crystallized on the surface of Au electrode modified using thiol graphene in advance. Due to the synergistic effect

We put forward an idea that the boundary entropy associated with integrable massless flow of thermodynamic Bethe ansatz (TBA) is identified with tachyon action of boundary string field theory. We show that the temperature parametrizing a massless flow in the TBA formalism can be identified with tachyon energy for the classical action at least near the ultraviolet fixed point, i.e., the open str...
