BACKGROUND Remediation of tert-butyl alcohol (TBA) in subsurface waters should be taken into consideration at reformulated gasoline contaminated sites since it is a biodegradation intermediate of methyl tert-butyl ether (MTBE), ethyl tert-butyl ether (ETBE), and tert-butyl formate (TBF). The effect of temperature on TBA biodegradation has not been not been published in the literature. METHODS...

Real-time heuristic search algorithms are used for planning by agents in situations where a constantbounded amount of deliberation time is required for each action regardless of the problem size. Such algorithms interleave their planning and execution to ensure real-time response. Furthermore, to guarantee completeness, they typically store improved heuristic estimates for previously expanded s...

AIM The present study was conducted to evaluate the physico-chemical and microbiological characteristics of chicken nuggets coated with sodium alginate (SA) coatings at refrigerated (4±1°C) and frozen (-18±1°C) storage condition at regular periodic intervals. MATERIALS AND METHODS Chicken meat nuggets were separated into three groups: Uncoated control (C), coated with alginate coating (T1), a...

1. The anabolic agent trenbolone acetate (3-oxo-17beta-hydroxy-4,9,11-oestratriene acetate; TBA) given subcutaneously to female rats increased their growth rate compared with that of the placebo-treated controls. 2. The increased growth rate of the TBA-treated rats was not a consequence of an increased water retention. The TBA-treated rats had a significantly higher (P less than 0.01) total car...

Structure and bonding patterns in tert-butanol (TBA)−water mixtures are investigated by using molecular dynamics simulations with the effective fragment potential (EFP) method. EFP is a model potential in which all parameters are obtained from a set of ab initio calculations on isolated fragment molecules. Mixed-basis EFP potentials (called “EFPm”) for water and TBA molecules were prepared and ...

A thrombin binding aptamer (TBA) is a synthetic 15-nt DNA oligomer that binds human alpha thrombin with high specificity and reversibly suspends the coagulation cascade and platelet formation. It has been established that TBA folds intramolecularly into a G-quadruplex (GQ) structure in solution, forming two G tetrads and three loops1. Two TT loops play a critical role in recognizing the target ...

The effect of aqueous solutions of ascorbic acid (AA) on the rancidity development in Cobia (Rachycentron canadum) fillets during frozen storage was studied. Cobia fillets were treated with ascorbic acid (AA 0.25% and AA 0.5%) then stored at -18°C up to 6 months. Rancidity development was measured by several biochemical indices including free fatty acids (FFA), peroxide value (PV), an...

Background and Objectives Despite advances in modern healthcare, Traditional Birth Attendants (TBA) have continued to be heavily utilized in rural communities in Nigeria. Major disparities in maternal health care in Nigeria remain present despite the goal of the United Nations Millennium Development Goal to reduce maternal mortality by 2015. The objective of this study is to review the contribu...

OBJECTIVE to describe the specific characteristics of one model of training traditional birth attendants (TBAs) in Guatemala. DESIGN participant observation, unstructured and semi-structured interviews undertaken between 1997 and 2003 to gather the data to report on the characteristics of this training programme as it is evolving in the field. SETTING the birth centre site of Ixmucane in An...
