1. A MAMMAL SPECIES NEW FOR IRAN: GAZELLA GAZELLA PALLAS, 1766 (ARTIODACTYLA: BOVIDAE)
Volume 4, Issue 2 , Spring 1993

Abstract
  This paper provides evidence for the presence of Gazella gazella on Fmur Island of Iran in the Persian Gulf. The species has not hitherto been reported from Iran. Based on univariate and multivariate analysis of a number of morphological features of the skull including horn length, premaxillae type, ...  Read More

3. EXTRACTION-SPECTROPHOTOMETRIC DETERMINATION OF AMMONIUM ION BY DIBENZO- 18-CROWN-6 AND CALMAGITE
Volume 4, Issue 2 , Spring 1993

Abstract
  An extraction-spectrophotometric method for the determination of trace amounts of ammonium ion is described. Ammonium ion is effectively extracted as a neutral ternary complex NH . DB 18C6. calmagite at pH 3.0 into chloroform, followed by spectrophotometric determination at =48 5 nm. Molar absorptivity ...  Read More

4. THE KINETIC STUDY OF THE LINKAGE ISOMERISM IN [Co (NH ) NO ] F COMPLEX
Volume 4, Issue 2 , Spring 1993

Abstract
  In this research project, the nitrito nitro isomerization of [Co (NH3)5No2]F2 complex has been studied. Isomerization of this complex in the solid state follows a first order kinetics. The rate of isomerization at different temperatures was determined using a Fourier Transform Lnfrared Spectrophotometer. ...  Read More

5. SYNTHESIS AND CHARACTERIZATION OF MONO AND BIS HEXAMETHYLENETETRAMINE IRON(II1) CHLORIDE IN NONAQUEOUS SOLVENT (CHCI )
Volume 4, Issue 2 , Spring 1993

Abstract
  Mono and bis hexamethylenetetramine iron(III) chloride, Fe(N C ,H ) CI (I) and Fe(N C ,H ) Cl (II) were synthesized by the reaction of iron(III) chloride and hexamethylenetetramine (HMTA) in chloroform. Chemical analysis and spectral results show the coordination of HMTA to the iron(III). Electronic ...  Read More

6. STUDY OF CYCLOREVERSION OF NTTRONE-CY CLODIMERS
Volume 4, Issue 2 , Spring 1993

Abstract
  A series of 1,3-dipolar cycloaddition reactions are carried out using cyclodimers of simple nitrones and various dipolarophiles; substituted isoxazolidines are isolated and identified. It is proved that such cyclodimers, in solution, are in equilibrium with their corresponding nitrones and enamines. ...  Read More

7. SYNTHESIS OF SOME SUBSTITUTED NAPHTHALENES VIA BENZYNE AND THEIR 13C-NMR AND 'H-NMR STUDIES
Volume 4, Issue 2 , Spring 1993

Abstract
  Aprotic diazotization of anthranilic acid with isoamylnitrite or amylnitrite gave benzenediazonium-2- carboxylate. Subsequent thermal decomposition of this diazonium salt (in situ) in 1,2-dichloroethane as a solvent at 85OC and in the presence of 2,5-diethyl-3,4-diphenylcyclopentadienonaes a trapping ...  Read More

8. SYNTHESES, ANTIBACTERIAL AND ANTIFUNGAL ACTIVITIES OF 2-ARYL-4- QUINOLINE- CARBOXAMIDE DERIVATIVES
Volume 4, Issue 2 , Spring 1993

Abstract
  Reaction of aryl methyl ketone with isatin in the presence of a base afforded 2- arylquinoline-4-carboxylic acid (3). Reaction of diazomethane with compound 3 yielded the ester 4. Compound 5 was prepared from the reaction of N, N'-dialkylethyl (or propyl) arnine with 4. Addition of hydrazine hydrate ...  Read More

11. CHARACTERIZATIONS OF EXTREMELY AMENABLE FUNCTION ALGEBRAS ON A SEMIGROUP
Volume 4, Issue 2 , Spring 1993

Abstract
  Let S be a semigroup. In certain cases we give some characterizations of extreme amenability of S and we show that in these cases extreme left amenability and extreme right amenability of S are equivalent. Also when S is a compact topological semigroup, we characterize extremely left amenable subalgebras ...  Read More

12. A BAYESIAN APPROACH TO COMPUTING MISSING REGRESSOR VALUES
Volume 4, Issue 2 , Spring 1993

Abstract
  In this article, Lindley's measure of average information is used to measure the information contained in incomplete observations on the vector of unknown regression coefficients [9]. This measure of information may be used to compute the missing regressor values.  Read More

13. A STUDY OF SMALL VACANCY CLUSTERS IN IRON USING MANY BODY POTENTIAL
Volume 4, Issue 2 , Spring 1993

Abstract
  Computer simulation techniques are employed to obtain binding energies of 2,3 and 4 vacancy clusters in a -iron using the Finnis Sinclair many body potential. The results are compared with earlier pair potential calculations. The many body potential is found to be quite successful in simulating vacancy ...  Read More

14. A THEORY OF VACUUM TUNNELING MICROSCOPY1
Volume 4, Issue 2 , Spring 1993

Abstract
  A theory for tunneling between a real surface and a model probe tip, applicable to the "scanning tunneling microscope" is presented. The tunneling current is found to be proportional to the local density of states of the surface, at the position of the tip. It can be shown that the tunneling conductance ...  Read More
