1. DETERMINATION OF PHYLOGENlETIC ALLIES IN SOME SPECIES OF CROCUS IN IRAN THROUGH THE STUDY OF SOLUBLE PROTEINS, PEROXIDASES AND POLYPHENOL OXUDASES
Volume 9, Issue 4 , Autumn 1998

Abstract
  The taxonomic affinity of six species of Crocus (C, cancellatus subsp. Damascenus C. almehensis, C. gilanicus, C. sativus, C.pallassi subsp. haussknechtii,C. speciosus subsp. speciosus) from Iran were studied usingdifferent electrophoresis techniques. The similarity index of the species was computed ...  Read More

2. APPLICATION OF TWO-DIMENSIONAL ELECTROPHORESIS AND NIH 3T3 CELL TRANSFECTION ASSAY IN THE STUDY OF TUMOR-AS SOCIATED PROTEINS AND GENOMIC DNA TUMOROGENICITY IN MALIGNANT HUMAN ESOPHAGEAL SPECIMENS
Volume 9, Issue 4 , Autumn 1998

Abstract
  Total protein and DNA extracted from histologically diagnosed normal nonmalignant and esophageal tumor tissues were used for analysis of polypeptides pattern by two-dimensional gel electrophoresis and DNA transforming activity in NIH 3T3 cell transfection assay, respectively. In comparison to normal ...  Read More

3. KINETIC DETERMINATION OF ASCORBIC ACID a WITH SPECTROPHOTOMETRIC DETECTION
Volume 9, Issue 4 , Autumn 1998

Abstract
  A simple and rapid method has been developed for the determination of ascorbic acid in fruit and pharmaceutical products. The method is based on the measurement of the reaction rate between ammonium molybdate and ascorbic acid in acidic media. The reaction was monitored spectrophotometrically at 800 ...  Read More

4. SPECTROPHOTOMETRIC STUDY OF THE THERMODYNAMICS AND KINETICS OF CHARGE-TRANSFER COMPLEXATION OF DIBENZO- 18-CROWN-6 WITH IODINE IN CHLOROFORM SOLUTION
Volume 9, Issue 4 , Autumn 1998

Abstract
  The charge-transfer complexation reaction between iodine and dibenzo- 18-crown- 6 (DB18C6) has been studied spectrophotometrically in chloroform solution at different temperatures. The resulting donor-acceptor complex was formulated as (DB 18C6…I )I . The spectrophotometric results , as well as ...  Read More

5. AROMATIZATION OF 1 , CDIHYDROPYRIDINES WITH OXYGEN OR AIR USING MANGANESE AND COBALT SALTS OF p-AMINOBENZOIC ACID SUPPORTED ON SILICA GEL AS OXIDIZING CATALYSTS
Volume 9, Issue 4 , Autumn 1998

Abstract
  Hantzsch 1,4-dihydropyridines are oxidized to the corresponding pyridine derivatives using oxygen or air and a mixture of the manganese and cobalt salts of parninobenzoic acid supported on silica gel as the catalysts. Reactions are clean and the catalysts can be recovered easily and reused repeatedly.  Read More

6. REACTIONS OF DIHYDROPYRIDINES WITH BENZYNE
Volume 9, Issue 4 , Autumn 1998

Abstract
  Reactions of 1 ,Zdihydropyridines (la-c) and 1,4-dihydropyridines (2a-c) in the presence of benzyne (3) under thermal conditions, and in the case of (2c) under photochemical conditions, have been investigated. Benzyne acts as an oxidizing agent to convert dihydropyridine (la) and (2a) to the corresponding ...  Read More

7. PHY SICO-CHEMICAL CHARACTERISTICS OF MINERALIZING FLUIDS AT THE KAMARMEHDI MINE, TABAS REGION, IRAN
Volume 9, Issue 4 , Autumn 1998

Abstract
  The data obtained from field and geothermometric studies and also the REE composition of fluorites associated with lead mineralization at the Kamar-Mehdi mine are compatible with a structurally controlled, fissure filling, epigenetic, hydrothermal origin. Homogenization and last ice melting temperatures ...  Read More

8. CHEBYSHEV SUBALGEBRAS OF JB-ALGEBRAS
Volume 9, Issue 4 , Autumn 1998

Abstract
  In this note, we characterize Chebyshev subalgebras of unital JB-algebras. We exhibit that if B is Chebyshev subalgebra of a unital JB-algebra A, then either B is a trivial subalgebra of A or A= H R .l, where H is a Hilbert space  Read More

9. SOME POINTS ON CASIMIR FORCES
Volume 9, Issue 4 , Autumn 1998

Abstract
  Casimir forces of massive ferrnionic Dirac fields are calculated for parallel plates geometry in spatial space with dimension d and imposing bag model boundary conditions. It is shown that in the range of ma>>l where m is mass of fields quanta and a is the separation distance of the plates, it is ...  Read More

10. EEDF MEASUREMENTS AND EXCITATION PROCESSES IN THE VICINITY OF A HELIUM DISCHARGE CONSTRICTION
Volume 9, Issue 4 , Autumn 1998

Abstract
  Axial distributions of plasma and floating potentials, electron number density and the electron energy distribution function (EEDF) have been measured in the double layer (DL) region of an He discharge constriction. Excitation processes in the constriction region are studied. Using a linearization ...  Read More
