Silica chloride converted benzyl or tert-butyl esters to the corresponding acid chlorides and alkyl chlorides. It also converted benzyl or tert-butyl phenyl ethers to the corresponding allcyl chlorides and phenol

Radiation enhanced diffusion at the surface of metals has been observed and studied for low-energy nitrogen ions at the surface of copper. The displacement of the target atoms during irradiation creates vacancies and ...

Five genera and ten species of the tribe Aeliini Still from the Indo-Pakistan region are keyed, compared to their closest allies and their geographical distribution given. A description of all the above genera and species ...

An amoniumvanadate plus sodium molybdate mixed modifier Graphite Furnace Atomic Absorption Spectrometric method has been developed for determination of traces of lead in drinking water. The concentration of lead in the ...

This paper addresses the problem of testing simple hypotheses about the mean of a bivariate normal distribution with identity covariance matrix against restricted alternatives. The LRTs and their power functions for such ...

Papaver fugax Poiret population Khalkhal was shown to contain four major alkaloids, roemerine (0.19%), mecamberine (0.39%), liriodenine (0.20%) and salutaridine (0.10%). Papaver caucasicum M. B. population Elika was shown ...

Ligands derived from 8-quinoline, 6-quinoline, 1 -isoquinoline, and 5-isoquinoline were synthesized. These compounds have been used as ligands for complexation of transition metals, such as copper(II) and nickel(II). ...

Electrophoresis of proteins, especially seed proteins, and karyological studies are useful techniques for determining species and solving the problems of modern taxonomy. The present study was carried out on two species ...

Interaction between DNA and histone H, was investigated in the presence and absence of sodium-n-dodecyl sulphate (SDS) and dodecyl trimethylammonium bromide (DTAB) at temperatures of 27 and 37?C, in 2.5 mM phosphate ...

In this paper among many other things we prove that the topological left amenability and left amenability of a weighted hypergroup (K, ?) are equivalent. For a normal subgroup H of K, we define a weight function ?? on ...

Cerium (IV) has a catalytic effect on the very slow redox reaction between gallocyanine and bromate in acidic media. The reaction was monitored spectrophotometrically at 525 nm by a fixed time method of 4.0 rnin from ...

Two strains, HG104 and ASSO, were isolated Crom the soil of Tehran's suburbs. Taxonomic studies showed thatHG104 and AS50 belong to Mycobacterium spp. and Brevibacterium spp. respectively, which produce antibacterial ...
