We present an R-band and J-band photometry of an optical transient which is likely to be associated with the gamma-ray burst event GRB 971214. Our first measurement took place 13 hours after the gamma-ray event. The brightness decayed with a power-law exponent α = −1.20 ± 0.02, which is similar to those of GRB 970228 and GRB 970508 which had exponents of α = −1.10 ± 0.04 and α = −1.141 ± 0.014 ...

A comparison was made of the dental health of children aged 4-5 and 9-10 in two Scottish towns, one with fluoridated drinking water and the other without. Striking differences were observed. A 44% reduction in decayed, missing, and filled deciduous teeth was found in 4-5 year-olds in the fluoridated compared with the non-fluoridated town and a 50% reduction in decayed, missing, and filled perma...

Most of the methods adopted for processing of decayed fruits and degradation of wastes are not economical. In order to achieve 100% resource recovery from wastes, a novel type of waste treatment is to be followed, so that, the recovered byproducts could be used as biofertilizers. The objective of this study is identification of bacteria for studying their phenotypic and genotypic characters usi...

Objectives: To validate the PUFA/pufa index and to assess the prevalence and severity of oral conditions related to untreated dental caries. Methods: Pufa index records the presence of pulpal exposure (P/p), ulceration caused by sharp edges of dislodged tooth fragments (U/u), fistula (F/f) and abscess (A/a) formation in grossly decayed teeth. Results: Good Kappa values shows reliability of the ...

AIM AND OBJECTIVE The objective is to assess the prevalence of caries in children with perinatal human immunodeficiency virus (HIV) infection. MATERIALS AND METHODS Oral examination was performed on children aged 2-12 years with perinatal HIV infection who stayed at 'Calvary Chapel home of hope for special children' to assess decayed, missing, or filled primary teeth/decayed, missing, or fill...

Soils and decayed plant litter contain significant quantities of chlorinated aromatic polymers that have a natural but largely unknown origin. We used cupric oxide ligninolysis coupled with gas chromatography/mass spectrometry to show that Curvularia inaequalis, a widely distributed litter ascomycete, chlorinated the aromatic rings of lignin in wood that it was degrading. In aspen wood decayed ...
