Synthesis, characterization and application of polyacrylamide grafted bioflocculants (TMT-1-g-PAM 2 and TST-1-g-PAM 3)
… wastewater treatment. Bioflocculants (TMT-1 and TST-1) produced by Bacillus pumilus JX860616 and a consortium of Bacillus pumilus JX860616 and Bacillus subtilis CSM5, respectively, were grafted with acrylamide chains using a microwave initiated method. To optimize the synthesis of the grafted …

A study to evaluate immunodiagnostic tests for tuberculosis infection and determinants of TB infection in a population of health care workers in the Western Cape of South Africa
… TB infection using both tuberculin skin test (TST) and IGRA assays in a sample of health care workers. * Evaluate change in interval test response over one year to determine annual risk of infection and determinants associated with test conversion. Methods: Participants completed a …

Assessment of the Tube Suction Test for Identifying Non-Frost-Susceptible Soils Stabilized with Cement
… effects of frost heave. The tube suction test (TST) is one possible method for determining the frost susceptibility of soils in the laboratory. The purpose of this research was to assess the utility of the TST for identifying non-frost-susceptible (NFS) materials stabilized with cement. This …

Utility of newer technologies for the diagnosis of active and latent tuberculosis
Since the 1800s the tuberculin skin test (TST) has been the only available test for latent tuberculosis (LTBI). Recently, interferon-gamma release assays (IGRAs) have been developed which are based upon the responses of peripheral blood effector cells to M.tb-specific antigens [early secretory …

First Principles Dynamics and Coarse-Grained Characterization of Photoisomerization in Complex Environments
… to which traditional transition state theories (TSTs) do not necessarily apply. To quantify the rates of such non-TST reactions, we have applied non-linear dimensionality reduction techniques to dynamical simulation data. Such techniques permit definition of simple, 1-dimensional reaction paths …

The efficacy of intermittent directly observed isoniazid in preventing tuberculosis in HIV-infected adults with advanced disease
… with a positive tuberculin skin test (TST), but not in those with a negative TST. However, there are insufficient data on patients with advanced HIV disease from high tuberculosis incidence areas. It is important to exclude tuberculosis prior to such preventive therapy, but this can be …

A quantitative characterization of tuberculin skin test indurations using hyperspectral imaging to enable automated latent tuberculosis screening
… 90% by the year 2035. The tuberculin skin test (TST) is the most widely used test for LTBI in low- and middle-income countries (LMICs). It involves the injection of tuberculin into the forearm skin of a participant. An induration – a subdermal lump – forms at the injection site 48 – 72 hours …

Cobertura vegetal e a temperatura de superfície no meio intraurbano: um estudo em Salvador
… com as Temperaturas de Superfície Terrestre (TST) no ano de 2016 em Salvador, cidade tropical brasileira, com emprego dos Sistemas de Informações Geográficas (SIG) e o Sensoriamento Remoto. Previamente foi construído um conceito orientador para o verde urbano e observadas as alterações na …

Mobile phone-based evaluation of talent tuberculosis infection
The tuberculin skin test (TST) is the most widely used method for detecting latent tuberculosis (TB) infection (LTBI) in adults and active TB disease in children. This work presents the development of a screening tool to detect LTBI's, which works in conjunction with the TST and serves as an …

Kinetic Studies of Hydroxyl and Hydrogen Atom Reactions
… (LP-RF) technique. The transition state theory (TST) analysis coupled with the measurements support the suggestion that the reaction shows significant curvature in the Arrhenius plot. The LP-RF technique was also used to measure the rate constant of the H + CH3Br reaction over the temperature …

The incidence of tuberculosis in adolescents in the context of proposed TB vaccine trials
… infection using both the tuberculin skin test (TST) and an interferon gamma release assay, the QuantiFERON® TB Gold (in-tube) assay (QFT). They were also screened for TB disease using an algorithm composed of a set of screening tests. They were followed up for at least two years for incident TB …

The stories of how two different student teaching models impacted teacher identity: six narratives of beginning teachers
… in a traditional student teaching placement (TST). A collective case study research design was used to gain an understanding of the complex process of constructing a professional identity. Within-case analysis and between-case analysis found that although the six research participants shared …

Predicting Changes in Individual Wellbeing Scores: Mixed Effects Models using Sleep Data from Wearables
… (SRI and IS), total sleep time as duration (TST), and combined regularity and total sleep time (SRI and TST, IS and TST) for alertness and energy over 2-4 nights. MERF outperformed other models in Mean Absolute Error (MAE), for all time split scenarios. This research further emphasizes the …

Effects of Restraint Stress on Sleep in the Mouse.
… (REM) sleep and total sleep time (TST) in the mouse. In contrast to the anecdotal notion that stress uniformly produces insomnia, it was hypothesized that stress induced sleep disruptions would vary as a function of the intensity and chronicity of stressor exposure. A repeated …

Integrated geological and petrophysical investigation on carbonate rocks of the middle early to late early Canyon high frequency sequence in the Northern Platform area of the SACROC Unit
… tracts (HST) and transgressive systems tracts (TST) is aggradational. And, the reservoir rocks representing the HST are more porous and permeable than those of TST. In addition to that, it was detected that the diagenetic overprint on the HST reservoir rocks is more than that of the TST. …

Integrated approach to solving reservoir problems and evaluations using sequence stratigraphy, geological structures and diagenesis in Orange Basin, South Africa
… to 13.134 %, and -2.644 to 16.180 % in the LST, TST, and HST, respectively. While δ13C isotope values range from -25.667 to -12.44 %, -27.862 to -6.954% and -27.407 to -19.935 % in the LST, TST, and HST, respectively. The plot of δ18O versus δ13C shows that the sediments were deposited in shallow …

User-interface design and evaluation in a mobile application for detecting latent tuberculosis
… infection (LTBI), is the tuberculin skin test (TST), for which an induration response on a patient’s arm is an indication of LTBI. The test requires the patient to return to a clinic 48 to 72 hours after TST administration for assessment of the response. This is a challenge because of financial …
