Sample processing methods

Drug-resistant Tuberculosis (DR-TB) is challenging public health problem in countries with high tuberculosis prevalence and limited resources. Developing and applying the most appropriate and effective methods for diagnosing DR-TB from clinical samples is necessary, allowing a more rapid detection method for large-scale screening.

In this study, we used traditional methods to isolate and screen for fungal laccases that have potential for use in the textile industry (dye decolorization) and a molecular marker to identify studied samples. Fifteen strains of basidiomycetes were isolated and screened for laccase activities on phenol, guaiacol and RBBR. Five strains showed positive laccase activities on all three substrates.

We report a facile process to fabricate cuprous thin films by thermal oxidation of copper substrates. Structure and phase identification were studied by X-ray diffraction measurement and Raman spectroscopy. Scanning electron microscopy was utilized to study surface morphology of the as-fabricated thin films and optical properties of the samples were investigated by diffused reflectance spectroscopy.

Instead of running hundreds or thousands of neutronics calculations, we therefore investigate the possibility to take those many cross-section file samples and perform ‘cheap’ sensitivity perturbation calculations. This is efficiently possible with the NEA Nuclear Data Sensitivity Tool (NDaST) and this process we name the half Monte Carlo method (HMM).

The concept of change management has been evident for centuries. However, it has dramatically increased in the twenty first century as forces driving change are evolving at an increasing speed and the effects of a worldwide recession can be felt. Throughout the years organisations have put in place various methods and methodologies to manage change which include; structural, process and technological change. However, it is interesting to note that despite the fact that change is a topical subject amongst academics and consultants, only one third of all change initiatives succeed.

These results indicate that sol-gel processing is a promising method for preparing Ni-rich cathode materials. The sample prepared under the optimal conditions had a well ordered hexagonal layered structure. The charge–discharge tests showed that the initial capacities of the sample were 220.456 and 185.937 mAhg -1 at the discharge rate of 0.1 C between 3.0 and 4.3 V, respectively. The capacity retention ratio was 81.36 % at 1 C after 50 cycles.

This leaves a sample of 931 districts from 50 MSAs. In spite of the serious limitations in the CCD data, the pattern of results in Panel D is quite similar to that in Panel C. Again, the student quality index is a strong predictor of completion rates, but its coefficient is (insignificantly) smaller in high-choice than in low-choice MSAs....
