background & aim: tetranychus urticae koch is one of the most important pests of crops, ornamental and greenhouse plants in the world and, can damage to 900 plant species. resistances to pesticides and acaricides have guided researches to introduce new methods to control t. urticae. botanical pesticides are an important group of natural productions that are usually safer than conventional p...

Melia dubia Cav. of family Meliaceae is a fast growing, high value tree species native to India. Isolating DNA from matured dried leaves of M. dubia was difficult due to accumulation of secondary metabolites, majorly polyphenolics, which resulted in dark brown to black colour of the pellet. In this study, a modified STE-(Sucrose, Tris-HCl and Ethylene Diamine Tetra Acetic Acid) CTAB (hexadecylt...

The BRST cohomology analysis of Lian and Zuckerman leads to physical states at all ghost number for c < 1 matter coupled to Liouville gravity. We show how these states are related to states at ghost numbers zero(pure vertex operator states – DK states) and ghost number one(ring elements) by means of descent equations. These descent equations follow from the double cohomology of the String BRST ...

Since 1995 the school education sector has been a dominant focus for education for sustainabi li ty (EfS) in Austra lia (Tilbury, Coleman, & Garlick, 2005, p. 1). The commencement of the Austra lian Susta inable Schools In it iative (AuSSI) in 2003, with its whole school approach, dramatically increased this focus (Department of Education and Training, 2005b). The pilot for the Western Australi...

Meliacine, a peptide isolated from leaves of Melia azedarach L. inhibited the multiplication of Junin virus in Vero cells treated with the compound before infection (pre-treatment) or immediately after virus adsorption. Analysis of early events following infection demonstrated that meliacine blocks virus penetration by preventing the uncoating step. The addition of meliacine at different times ...
