Quantitative determination of adulterant in petroleum products viz diesel, petrol and kerosene is great challenge to police, revenue and forensic department. The literature methods are tedious, time consuming with large scope for errors. Viscosity measurement of known admixtures of diesel and kerosene at 40C give linear plot. The viscosity comparisons of unknown sample with known admixtures dir...

yersinia enterocolitica is newly included in the classification of both the invasive bacteria, e.g. shigella, and the toxicogenic bacteria, e.g. escherichia coli. five human strains and 45 environmental strains were used to produce y.enterocolitical enterotoxin at 40c, 240c and 370c using infant mouse assay. at 250c enterotoxin was produced by 10 environmental strains and by all of the 3 human ...

The structure of the as-made, hydrated form of ECR-40C, synthesized in the presence of (2-hydroxyethyl) trimethylammonium (HTMA) ions as an organic structure-directing agent (OSDA) and 2 wt% (relative to alumina in the synthesis mixture) of aluminosilicate zeolite UZM-22 with the MEI topology as seeds, has been determined using synchrotron powder X-ray diffraction and Rietveld analyses. Two dif...

Chicken eggshell waste is a promising source of CaO which can be converted into heterogeneous catalyst materials. The purpose this study was to utilize derived from breed chicken produce biodiesel cooking oil through the transesterification process. A total 4 g material mixed with 200 and 60 methanol, then mixture stirred at speed 700 rpm for 6 h ± 40C. produced analyzed using GC-MS elucidate v...

The results of BLAST analyses of partial nucleotide sequence of 16S ribosomal RNA gene of newly isolated strain N 6.1, possessing D-aminoacylase activity, revealed maximum of 83 % identity with Bacterial and Archaeal databases, indicating that the isolated bacteria belongs to a new species and even the new genus. The enzyme was more than 850 times purified with 2.7 % overall yield as a result o...

The paper presents the results of study temperature regime optimization for storing seeds tropical orchids on example Eulophia streptopetala Lindley and Stanhopea tigrina Batem ex Lindl. Mature were frozen at temperatures 18C, 40C or 80C a period 1, 3, 6 12 months, storage was +4C. Before after freezing, viability determined by visual tetrazole methods. After defrosting, sown plants grown from ...

The objective of this study was to evaluate the efficacy of EK extender alone or incorporation with CoenzymeQ10 (CoQ10) and/or soyphosphatidylcholine (SPC) in poultry semen and their effects on seminal traits during temporal storage at 40C for different time intervals (12 h, 24 h, and 36 h). Heterospermic pooled semen samples diluted (1:4) with EK, EK + SPC, EK+ CoQ10 and EK + SPC + CoQ10 exten...
