A bstract It has been recently realized that, in the case of polynomial potentials, exact WKB method can be reformulated terms a system TBA equations. In this paper we study various examples. We develop graphical procedure due to Toledo, which provides fast and simple way wall-crossing behavior When complemented with quantization conditions, equations used solve spectral problems exactly Quantu...

We apply the contour deformation trick to the Thermodynamic Bethe Ansatz equations for the AdS5 × S mirror model, and obtain the integral equations determining the energy of two-particle excited states dual to N = 4 SYM operators from the sl(2) sector. We show that each state/operator is described by its own set of TBA equations. Moreover, we provide evidence that for each state there are infin...

The thermodynamic Bethe ansatz (TBA) and the excited state TBA equations for an integrable spin chain related to the Lie superalgebra osp(1|2) are proposed by the quantum transfer matrix (QTM) method. We introduce the fusion hierarchy of the QTM and derive the functional relations among them (T -system) and their certain combinations (Y -system). Their analytical property leads to the non-linea...

The thiobarbituric acid (TBA) reaction, quantified by colorimetry or fluorimetry, is the method most widely used for studying lipid peroxidation in both laboratory animals and in humans with disorders. However, concerns regarding its analytical specificity have often been expressed, because TBA reacts with a wide variety of chemical species to produce a pink to red color. In this study, we reac...

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...
