Abstract Polygraphus proximus , a four-eyed fir bark beetle, is an invasive beetle species which has caused extensive damage to forests of Abies sibirica in southern and western Siberia the European part Russia. There high risk that pest insect will spread areas where it currently not considered present, such as Union. In these areas, threatens attack conifer various may result major environmen...

Flowers of Cassia fistula L. were collected from Lahore, Pakistan and extracted in methanol followed by separation n-hexane soluble compounds a separating funnel. The separated phase was analyzed GC-MS for identification various possible phytochemicals. Among the 31 identified compounds, predominant compound this fraction butanoic acid, methyl ester with 17.81% peak area 3-eicosene, (E)- (6.83%...

THE writer has previously described [1914] a method for the volumetric estimation of carbon, the essence of which is oxidation by a mixture of phosphoric acid and potassium dichromate and the measurement of the 002 produced. It was shown that where methyl groups are present the substance is not oxidised to carbon dioxide alone but to a mixture of carbon dioxide and acetic acid; for example, lac...

In the present research, synthesis of new 2-(3-chlorobenzyl)-1H-benzimidazole derivatives bearing Nbenzylidene, 1,2,4-triazole and N-acylhydrazone moiety is investigated. These novel compounds have been tested for their antimicrobial effects against two of Gram-positive bacterial strains, namely Bacillus subtilis and Staphylococcus epidermidis, and four Gram-negative bacterial strains which wer...
