The SuperNEMO experiment will search for neutrinoless double-beta decay ($0\nu\beta\beta$), and study the Standard-Model process ($2\nu\beta\beta$). technology can measure energy of each electrons produced in a ($\beta\beta$) decay, reconstruct topology their individual tracks. spectrum requires very accurate calibration to be carried out periodically. Demonstrator Module calibrated using 42 so...
Sclerotinia sclerotiorum is a phytopathogenicfungus that attacks more than 400 plant species of them medicinal plant. In this study the extract obtained from basal stalk rot of Helianthus annuus L., attacked by S. sclerotiorum, was subjected to the analysis of FTIR to identify the presence of beta-glucan. FT-IR spectrum showed four ranges of bands in 890 cm-1, two overlap band in 1047 and 1078 ...
Pseudomonas aeruginosa is an opportunistic pathogen which is naturally resistant to a large range of antibiotics like lots of Beta–Lactams (penicillins, cephalosporins and carbapenems) and may cause additional resistance after unsuccessful treatment. The understanding of beta-lactamase identification and detection in these bacteria is very valuable. In recent years a number of variety of new be...
Presence of extended spectrum beta-lactamases (ESBL) in bacteria is a growing health concern of global significance. The local, regional, national, and international epidemiological studies for extended spectrum beta-lactamases-producing Enterobacteriaceae and their encoding genes in foods are still incomplete. The objective of this study was to determine the occurrence of extended spectrum bet...
Thermoluminescence material LiF:Mg,Cu,P was produced using standard GR200 dopant concentrations and its emission and absorption spectrums was measured after beta irradiation. The alterations resulting from various thermal treatments, excessing the recommended temperatures namely 240ºC on the emission and absorption spectrums has been investigated. The main peak of absorption spectrum, which is ...
Among 99 clinical Klebsiella pneumoniae isolates resistant to cefoxitin and extended-spectrum cephalosporins, coexistence of AmpC (DHA-1, CMY-2, or CMY-8) and extended-spectrum beta-lactamases (CTX-M and/or SHV) was detected in a total of 35. The remainder produced AmpC (n = 42), extended-spectrum beta-lactamases (n = 9), metallo-beta-lactamases (n = 2), or none of these enzymes (n = 11). Pheno...
Production of extended-spectrum beta-lactamases and plasmid-mediated AmpC enzymes was investigated among 291 Escherichia coli and 282 Klebsiella pneumoniae isolates that showed decreased susceptibilities to extended-spectrum cephalosporins from seven Taiwanese medical centers. CTX-M-type and SHV-type enzymes were the most prevalent extended-spectrum beta-lactamases. CMY-2-like and DHA-1-like be...
