A series of Ni/SBA-15/Al(2)O(3)/FeCrAl metal monolithic catalysts with Ni loadings varying between 3 % and 16 % were prepared, and their structure was characterized by various techniques. The catalytic activity of the catalyst for methane reforming with CO(2) leading to synthesis gas was evaluated using a fixed-bed reactor. The results indicate good catalytic activity of the Ni/SBA-15/Al(2)O(3)...
BACKGROUND Mass vaccination campaigns of the population aged 1-29 years with 1 dose of group A meningococcal (MenA) conjugate vaccine (PsA-TT, MenAfriVac) in African meningitis belt countries has resulted in the near-disappearance of MenA. The vaccine was tested in clinical trials in Africa and in India and found to be safe and highly immunogenic compared with the group A component of the licen...
Small bowel adenocarcinoma(SBA)is a rare neoplasm presenting usually in elderly patients as single tumour. Multiple synchronous SBA is unique and difficult to diagnose due non-specific presentations.Faecalomas have been described association with Hirschsprungs disease, psychiatric patients, Chagas both inflammatory neoplastic conditions, suffering chronic constipation.We herein report case of m...
Mesoporous SBA-15 silica materials functionalized with and without carboxylic acid groups were used to effectively control the morphology of Pt crystals, and the materials thus obtained were applied to methanol oxidation reactions. The Pt particles aggregated to form long spheroids inside the channels in pure SBA-15. When carboxylic acid groups were utilized, the SBA-15(-COOH) material facilita...
A magnetic nanoparticle conjugated mesoporous nanocatalyst (Fe(3)O(4)@mesoporous SBA-15) with a high surface area has been synthesized by chemical conjugation of magnetite (Fe(3)O(4)) nanoparticles with functionalized mesoporous SBA-15. Functionalized mesoporous SBA-15 containing surface carboxyl and amino groups was synthesized via the thiol-ene click reaction of cysteine hydrochloride and vin...
In this paper, a novel method for single-channel speech enhancement based on Kalman filtering is proposed. Instead of applying the Kalman algorithm for full-band speech or uniform sub-band speech, speech enhancement is performed by applying the Kalman algorithm to non-uniform sub-band signals obtained from the decomposition of whole-band speech using gammatone filters. Simulation results indica...
We compared individual trait variability in 65 male and 81 female patients with spina bifida occulta (SBO) or spina bifida aperta (SBA) against 170 male and 200 female subjects randomly selected Serbian subjects without these conditions. Variability was evaluated by direct observation of 15 homozygous recessive traits (HRT), while gender was evaluated separately. Individual trait variations bet...
in synthetic aperture radar (sar) imagery, ship-sea contrast can be significantly improved when the polarimetric information is used, compared with information from a single channel sar. the constant false alarm rate (cfar) detection algorithm based on the alpha-stable (as) distribution model is a descent method for ship detection in sea. the most important step in this method is the parameter ...
BACKGROUND Single Best Answer (SBA) questions are widely used in undergraduate and postgraduate medical examinations. Selection of the correct answer in SBA questions may be subject to cueing and therefore might not test the student's knowledge. In contrast to this artificial construct, doctors are ultimately required to perform in a real-life setting that does not offer a list of choices. This...
Mouse spleen cells sequentially agglutinated by soybean agglutinin (SBA) and peanut agglutinin (PNA) previously had been shown to be sufficiently depleted of graft-versus-host activity to allow reconstitution of lethally irradiated allogeneic recipient mice. We have now tested the extent of T-cell depletion in this cell fraction by various in vitro assays, including cytotoxicity testing with an...
