1. ELUCIDATION OF pK VALUES FOR ACTIVE SITE OF HORSERADISH PEROXIDASE AND BINDING STUDY OF INTERACTION WITH N-PHENYL BENZHYDROXAMIC ACID USING A SPECIAL DIFFERENCE SPECTROPHOTOMETRIC TECHNIQUE
Volume 8, Issue 4 , Autumn 1997

Abstract
  The binding behavior of a competitive inhibitor, N-phenylbenzhydroxamic acid (BHA) against horseradish peroxidase (HRP) was studied in order to understand and predict the interaction mechanism of hydrogen donors with the enzyme. The dissociation constants of the complexes of HRP-BHA, HRP-donor and ...  Read More

2. PRODUCTION, RELEASE AND THERMAL CHARACTERIZATION OF CELLULOLYTIC ENZYME FROM CELLULOMONAS sp. STRAIN "0"
Volume 8, Issue 4 , Autumn 1997

Abstract
  Cellulase production by a Cellulomonas sp., isolated in 1985 from forest humus soil along the border of the Caspian Sea in Iran, was investigated. This strain secreted endo-and exo-cellulases in the culture medium, but some of the enzymes produced remained cell membrane bound. Cell bound enzymes were ...  Read More

3. A SIMPLE MODEL FOR THE ESTIMATION OF DIELECTRIC CONSTANTS OF BINARY SOLVENT MIXTURES
Volume 8, Issue 4 , Autumn 1997

Abstract
  A simple and reliable method for quick estimation of the dielectric constant of a binary solvent mixture is proposed. The validity of the proposed method has been tested for a broad range of binary solvent mixtures  Read More

4. DIFFERENTIAL PULSE POLAROGRAPHIC DETERMINATION OF OSMIUM BY CATALYSIS OF PYROGALLOL-RED BROMATE REACTION
Volume 8, Issue 4 , Autumn 1997

Abstract
  A highly sensitive differential pulse polarographic (DPP) method has been developed for the determination of trace amounts of osmium, based on the catalytic effect of osmium (VIII) on the oxidation of pyrogallol red (PGR) by sodium bromate at pH 7.00 and 25.0 0.1 ? C. The reaction rate was monitored ...  Read More

5. SYNTHESIS OF 1,2,4-TRIAZINO [3,4-C] [I ,2,4] BENZOTRIAZINE, A NOVEL HETEROCYCLIC SYSTEM
Volume 8, Issue 4 , Autumn 1997

Abstract
  3-Mercapto-1,2,4 benzotriazine (1) was methylated by methyl iodide in the presence of base to afford 1,2-dihydro-3-methyhercapto-1, 2,4 benzotriazine (2). The latter was reacted with hydrazine hydrate to give the corresponding 3-hydrazine derivative (3). Compound (3) on condensation with phenacyl ...  Read More

6. EXTENSION OF LINEAR ISOTHERM REGULARITY TO LOWER DENSITY RANGE
Volume 8, Issue 4 , Autumn 1997

Abstract
  The general equation of state which was found for dense fluids, both compressed liquids and dense supercritical fluids, namely "Linear Isotherm Regularity," is extended to the lower density range, specifically for densities lower than the Boyle density. This new equation of state which is called "ELIR" ...  Read More

7. PALYNOSTRATIGRAPHY AND PACAIEOGEOGRAPHY OF EARLY PEFIMM STRATA IN THE ZAGROS BASIN, SOUTHEAST SOUTHWEST IRAN
Volume 8, Issue 4 , Autumn 1997

Abstract
  A totall of 500 Early Permian samples from the Chal-i-Sheh Formation in the Zagros Basin were examined palynollogically in order to determine the stratigraphical age of the formation and to assess the palaeogeopaphicd relatianships of this basin to the Southern and Northern Hemispheres during the ...  Read More

8. FOCAL POINT AND FOCAL K-PLANE
Volume 8, Issue 4 , Autumn 1997

Abstract
  This paper deals with the basic notions of k-tautimmersions . These notions come from two special cases; that is, tight and taut immersions. Tight and taut based on high and distance functions respectively and their basic notions are normal bundle, endpoint map, focal point, critical normal. We generalize ...  Read More

9. FLOWS AND UNIVERSAL COMPACTIFICATIONS
Volume 8, Issue 4 , Autumn 1997

Abstract
  The main purpose of this paper is to establish a relation between universality of certain P-compactifications of a semitopological semigroup and their corresponding enveloping semigroups. In particular, we show that if we take P to be the property that the enveloping semigroup of a compactification ...  Read More

10. EFFECT OF FUSION REACTION PRODUCTS HEATING ON THE VOLUME IGNITION OF DT AND D3He FUEL PELLETS
Volume 8, Issue 4 , Autumn 1997

Abstract
  Laser fusion simulations are carried out for DT and D- He pellets by using a hydrodynamic code including heating from all charged reaction products and neutrons. It is shown that the inclusion of the side reactions and heating from all reaction products in the fuel pellets have an appreciable effect ...  Read More

11. THE THEORY OF PHOTOTHERMAL LENSING SPECTROSCOPY
Volume 8, Issue 4 , Autumn 1997

Abstract
  A general theoretical description of dual-beam photothermallensing spectroscopy is given. The results are valid for most general conditions, that is, for flowing as well as stationary media, for optically thick as well as optically thin media, and also for any transverse modes of incident pump beams  Read More
