1. ANTIAMOEBIC ACTIVITY OF RIND AND FLOWERS OF PUNICA GRANATUM LINN
Volume 4, Issue 1 , Winter 1993
Abstract
The antiamoebic activity of water soluble fractions of the rind and flowers of Punicu grunutum has been assessed. The in vitro and in vivo studies, carried out on a virulent strain of Entamoebu histotyticu, exhibited encouraging results Read More2. MOLECULAR ANALYSIS OF THE SULFUR REGULATORY CIRCUIT OF NEUROSPORA CRASSA
Volume 4, Issue 1 , Winter 1993
Abstract
The sulfur regulatory circuit of the filamentous fungus, Neurospora crassa, consists of a set of unlinked structural genes which encode sulfur catabolic and two major regulatory genes which govern their expression. The cys-3 regulatory gene encode a transacting regulatory protein which activates the ... Read More3. EFFICIENT PHOSPHOROUS-SULFUR BOND REDUCTION IN BICYCLIC THIAPHOSPHORANES WITH TRI-n-BUTYLTIN HYDRIDE
Volume 4, Issue 1 , Winter 1993
Abstract
High yield photolytic reduction of a series of thiaphosphoranes Z p SR to give Z p H with UV-light-induced tri-n-butyltin hydride through phosphoranyl radical Z p is described. This reaction is inhibited by a-methylstyrene and initiated by a radical initiator such as azobisisobutyronitrile Read More4. REACTION OF 4-METHYL- 1 2,4-TRIAZOLINE- 3,5-DIONE WITH DI AND TRI-SUBSTITUTED STYRENES S.E. Mallakpour* and G.B. Butler**
Volume 4, Issue 1 , Winter 1993
Abstract
2,4,6-Triisopropylstryrene was synthesized in a single step via the Witting Reaction from the corresponding aldehyde. The reaction of three styrene's derivatives, 2,6-dimethylstyrene, 2,4,6-trimethylstyrene, and 2,4,6- triisopropylstyrene with 4-methyl-l,2,4-triazoline-3,5-dion(M eTD) was investigated. ...

Volume 4, Issue 1 , Winter 1993
Abstract
In this work, one and two-dimensional lattices are studied theoretically by a statistical mechanical approach. The nearest and next-nearest neighbor interactions are both taken into account, and the approximate thermodynamic properties of the lattices are calculated. The results of our calculations ...

Volume 4, Issue 1 , Winter 1993
Abstract
The Paleozoic sediments of the Chal-i-Sheh area in southwestern Iran comprising of Mila Formation, Ilebek Formation and Faraghan Formation, were studied palynologically. The samples containing well-preserved palynomorphs include acritarchs, chitinozoans, scolecodonts and pollenlspores. A palynological ... Read More7. FIRST REPORT ON PLATINUM-GROUP MINERALS IN CHROMITITES J%OM NORTHWESTERN NEYRIZ OPHIOLITE, IRAN
Volume 4, Issue 1 , Winter 1993
Abstract
Electron-probe microanalyses and scanning electron microscopy of chrornitites from some ultramafic members of Neyriz ophiolite indicate that sulifides of platinum- group minerals (PGMs) occur as solid inclusions in chromite grains. Laurite with the general formula of (Ru ,Os ,lr ) S , and erlichmanite ... Read More8. ON THE STRUCTURE OF FINITE PSEUDO- COMPLEMENTS OF QUADRILATERALS AND THEIR EMBEDDABILITY
Volume 4, Issue 1 , Winter 1993
Abstract
A pseudo-complement of a quadrilateral D of order n, n, > 3, is a non-trivial (n+l)- regular linear space with n - 3n + 3 points and n + n - 3 lines. We prove that if n > 18 and D has at least one line of size n - 1, or if n > 25 , then the set of lines of D consists of three lines of size n -1, ... Read More9. BIFURCATION OF PERIODIC SOLUTION FROM AN EQUILIBRIUM POINT IN THE MULTIPARAMETER CASE
Volume 4, Issue 1 , Winter 1993
Abstract
We consider the bifurcation of periodic solutions from an equilibrium point of the given equation: x =F(x,?) , where x ? R , ? is a vector of real parameters ? , ? , ... , ? and F:R x R ->R has at least second continuous derivations in variables Read More10. A LOW TEMPERATURE SPECIFIC HEAT INVESTIGATION OF Cd Mn Se AND Cd Mn S
Volume 4, Issue 1 , Winter 1993
Abstract
The specific heat of Cd Mn Se (x = 0.01) and Cd , Mn S (x = 0.026) in the temperature range of 0.3 - 40K was measured. The measurements were carried out in different applied magnetic fields (H = 0,10,20, 28KG). The results were analyzed with a model which includes long range interactions. Calculations ...
