1. COMPARISON OF SEED PROTEINS ELECTROPHORESIS OF EIGHT SPECIES OF THE GENUS SUAEDA (CHENOPODIACEAE) IN IRAN
Volume 5, Issue 3 , Autumn 1994
Abstract
Seed proteins of eight species of the genus Suaeda (Chenopodiaceae) were compared by means of polyacrylamide disc gel electrophoresis. Different samples of the same species showed not less than 89% similarities, and geographical separation had no remarkable effect on seed protein patterns of the same ... Read More2. VARIATIONS OF GLUCOSE 6-PHOSPHATE DEHYDROGENASE ACTIVITY IN VARIOUS TISSUES INDUCED BY METABOLIC ALKALOSIS, ACIDOSIS AND DIABETES
Volume 5, Issue 3 , Autumn 1994
Abstract
The effects of chronic metabolic acidosis, alkalosis and alloxan-induced ketoacidosis on G6PD activity of rat kidney, liver and erythrocytes were studied. Metabolic acidosis significantly increased the activity of kidney enzyme (55%) but decreased the liver (43%) and erythrocyte (38%) enzyme activities. ... Read More3. EFFECTS OF SOME NOVEL ASCORBIC ACID-METAL COMPLEXES ON SELECTED BACTERIAL AND FUNGAL SPECIES
Volume 5, Issue 3 , Autumn 1994
Abstract
The antimicrobial activity of some novel ascorbic acid-metal complexes [bisascorbate complexes of copper (II), zinc(II), manganese (11), iron (111), cobalt(II), lead(II) and cadmium(II)] was investigated. Four standard strains of bacterial species - Staphylococcus aureus, Escherichia coli, Bacillus ... Read More4. PREPARATION AND MOLECULAR STRUCTURE OF 2-BENZYLAMINOPYRIDINE COPPER(1) COMPLEX
Volume 5, Issue 3 , Autumn 1994
Abstract
2-Benzylaminopyridine (HBAP) reacts with NaH in THF and generates the sodium salt (NaBAP). Further reaction of [Cu(TMEDA) ] [CuCl ] with one equivalent of this ligand in THF leads to the formation of a dimeric Cu(1) complex, [Cu (BAP)] . H 0. The molecular structure has been determined by using ... Read More5. COMPLEXES OF LEAD (II)*: CRYSTAL STRUCTURES OF L2Pb (NO,), AND L2Pb(SCN), L=Z(AMINOMETHYL) PYRIDINE
Volume 5, Issue 3 , Autumn 1994
Abstract
The reactions of Pb(N0 ) and Pb(SCN)2 with 2-(aminomethy1)pyridine (C H N = L) yielded colourless crystals of L Pb(N0 ) ( I ) and L Pb(SCN) , (2), respectively. Their structures were determined by X-ray crystallography. Crystal data: 1, monoclinic, P2 /c, a = 9.263 (4) ?, b = 7.783 (2) ?, c ... Read More6. SYNTHESIS OF SOME IMIDAZO [ I , 2-b] [l , 2,4] TRIAZINE AND N-ALKYLATED IMIDAZO [l , 2-b] [1 , 2,4]-TRIAZINES
Volume 5, Issue 3 , Autumn 1994
Abstract
A number of 3-amino-1, 2, 4-triazin-5 (2H)- ones(1) were synthesized and condensed with a-haloketones to give 2,6-disubstituted imidazo [1, 2-b] [1, 2, 4]-triazin-3 (4H)-ones (2). These compounds were reacted further with a - haloketones to yield N-alkylated products (3). Read More7. SYNTHESIS OF (k) - 6,8-DIHYDROXY-3- ISOPROPYL-7-METHYLISOCHROMAN
Volume 5, Issue 3 , Autumn 1994
Abstract
The title isochroman ( 8 ) was synthesized as a suitable substrate for acetoxylation studies leading to an intermediate of type (4), expected to afford, on condensation with diketen, the fungal metabolite "rotiorin" type linear product (1). Cyclocondensation of alcohol (6), obtained by the reduction ... Read More8. KINETIC SPECTROPHOTOMETRIC DETERMINATION OF MERCURY IN DIFFERENT MATERIALS BASED ON ITS INHIBITORY EFFECT ON THE BRILLIANT GREEN-SULFITE REACTION
Volume 5, Issue 3 , Autumn 1994
Abstract
A new kinetic method for the determination of Hg(II) based on its inhibitory effect on the Brilliant green-sulfite reaction at pH 6.5 is proposed. The reaction is followed spectrophotometrically at 615 nm by measuring the change in absorbance at the fixed time of 3.5 min after the initiation of the ... Read More9. ON THE LIFTS OF SEMI-RIEMANNIAN METRICS
Volume 5, Issue 3 , Autumn 1994
Abstract
In this paper, we extend Sasaki metric for tangent bundle of a Riemannian manifold and Sasaki-Mok metric for the frame bundle of a Riemannian manifold [I] to the case of a semi-Riemannian vector bundle over a semi- Riemannian manifold. In fact, if E is a semi-Riemannian vector bundle over a semi-Riemannian ... Read More10. ROTATIONAL ASSIGNMENT OF NEW BANDS IN THE NO , EXCITATION SPECTRUM IN THE SPECTRAL RANGE OF 15600 cm TO 15633 cm
