1. NUMERICAL TAXONOMIC STUDY OF THE IRANIAN SPECIES OF ALYSSUM L. BASED ON MORPHOLOGICAL CHARACTERS
Volume 7, Issue 3 , Summer 1996

Abstract
  The genus Alyssum L. belongs to the subtribe Alyssinae, tribe Alysseae and family Cruciferae (Brassicaceae). This genus is one of the largest genera of the family of Cruciferae in Iran, and seems to be the most problematic genus in which the boundary of certain species is not completely clear due ...  Read More

2. THE EFFECTS OF SALT STRESS ON THE SHOOT APICAL MERISTEM AND LEAF GENIERATION IN SUNFLOWER (HELIANTNUS ANNUUS L.)
Volume 7, Issue 3 , Summer 1996

Abstract
  Sunflower (Helictnthur annuus L. cvs Mehr Shafagh) seedlings were grown in nutrient solutions containing 20.5 to 70.4 mM NaCl and 0 as the control. The effects of salinity on developmental changes occurring in the shoot apices of plants were studied. At 20.5 mM NaCI concentration, the leaf emergence ...  Read More

3. THE STUDY OF CHROMOSOMES AND SOLUBLE PROTEINS IN FOUR SPECIES OF VINCA (V.ROSEA, V. MAJOR , V. MINOR, V.HERBACEA) GROWN IN IRAN
Volume 7, Issue 3 , Summer 1996

Abstract
  Indole ahloids of Vinca species are valued greatly in medical sciences, one reason being for their use as powerful anticancer agents. There are four species of Vinca in Iran: V. rosea, V. major, V. minor and V. herbacea. In previous investigations, we found that these plants have considerable alkaloid ...  Read More

4. POLAROGRAPHIC AND POTENTIOSTATIC REDUCTION OF CARBODIIMIDES: A MECHANISTIC STUDY
Volume 7, Issue 3 , Summer 1996

Abstract
  The polarographic reduction of aromatic carbodiimides in anhydrous aprotic solvents goes through a carbene intermediate by a diffusion controlled process in two one-electron steps. The first step is the rate-determining step and converts the carbodiirnide to a radical anion (6) that reduces further ...  Read More

5. ELECTROCHEMICAL BEHAVIOR OF GC, Pt AND Au ELECTRODES MODIFIED WITH THIN FILM OF COBALT HEXACYANOFERRATE
Volume 7, Issue 3 , Summer 1996

Abstract
  0A thin film of cobalt hexacyanoferrate (CoHCF), an analogue of mixed-valence Prussian blue, was deposited electrochemically on the glassy carbon, platinum and gold electrode surfaces in 0.5M KC1 solution. The electrochemical behavior of these modified electrodes show three couples of redox peaks by ...  Read More

6. SYNTHESIS AND CHARACTERIZATION OF AMINE(CHLOR0)COBALOXIME DERIVATIVES. APPROXIMATE VALUES OF THE ANGULAROVERLAP PARAMETER, ?, FOR THE COORDINATED AMINES
Volume 7, Issue 3 , Summer 1996

Abstract
  Four new complexes of the type [LCo ((DO)(DOH) pn) Cl] PF , where (DO) (DOH) pn = N , N '- propanediylbis (2, 3-butanedione2-imine3-oxirne)a nd L =morpholine (mrpln) (I), benzylamine (bzlan) (II), piperidine (pprdn)(III) and pyrrolidine (prldn) (IV) have been synthesized and characterized by elemental ...  Read More

8. ISOLATION AND STRUCTURAL ELUCIDATION OF THE FIRST KNOWN C-HOMOPROTOBERBERINE
Volume 7, Issue 3 , Summer 1996

Abstract
  A novel C-homoprotoberberine alkaloid, Hediamine (2), has been isolated from the roots of Berberis actinucantha (Berberidaceae). Conclusive proof for the structure of hediamine was obtained by its comparison with the isomeric lactam (4), by chemical transformation, and by means of spectroscopic techniques ...  Read More

9. SIMPLE DERIVATION OF FRANCK-CONDON INTEGRALS
Volume 7, Issue 3 , Summer 1996

Abstract
  The expressions foavibrational overlap integrals of the one-dimensional harmonic wavefunctions (centenxi about different equilibrium positions and having different frequencies) have been derived in a simple and straightforward way.  Read More

10. ON OPTIMAL NOZZLE SHAPES OF GAS-DYNAMIC LASERS
Volume 7, Issue 3 , Summer 1996

Abstract
  Pontryagin's principle is used to study the shape of the supersonic part of the nozzle of a carbon dioxide gas-dynamic laser whose gain is maximal. The exact shape is obtained for the uncoupled approximation of Anderson's bimodal model. In this case, if sharp corners are allowed, the ceiling of the ...  Read More

11. ON THE STATIONARY PROBABILITY DENSITY FUNCTION OF BILINEAR TIME SERIES MODELS: A NUMERICAL APPROACH
Volume 7, Issue 3 , Summer 1996

Abstract
  In this paper, we show that the Chapman-Kolmogorov formula could be used as a recursive formula for computing the m-step-ahead conditional density of a Markov bilinear model. The stationary marginal probability density function of the model may be approximated by the m-step-ahead conditional density ...  Read More

12. ON THE INFINITE ORDER MARKOV PROCESSES
Volume 7, Issue 3 , Summer 1996

Abstract
  The notion of infinite order Markov process is introduced and the Markov property of the flow of information is established.  Read More

13. OPTICAL STUDIES OF COLORED CHEMICAL SPECIES
Volume 7, Issue 3 , Summer 1996

Abstract
  Evanescent wave spectroscopy using thin optically transparent electrodes and multiple reflections allows unique observations of the electrochemical interphase since the region of solution sampled is typically 100 nm from the electrode in the visible spectral region. This technique is found to be highly ...  Read More
