2. KARYOTYPIC STUDY OF TRIFOLIUM SPECIES AND CULTIVARS IN IRAN
Volume 9, Issue 3 , Summer 1998

Abstract
  Trifolium species and cultivars are considered important forage crops iran , growing throughout the country. The present article considered the karyotypic details of Trvulim taxa using multivariate statistical analysis. Taxa studied included: Trifolim restylinatum (six populations: Shazand, Soriyan, ...  Read More

3. USE OF ORGANIC SOLVENTS FOR THE ENHANCEMENT AND LIFETIME INCREASING OF LUMINESCENCE IN FLUORIMETRIC APPLICATION BY FLUORESCAMINE
Volume 9, Issue 3 , Summer 1998

Abstract
  In this study, the fluorogenic efficiency of fluorescamine for spectrofluorimetric analysis of primary amines was investigated. Different mixtures of dichloromethane and other organic solvents were used for evaluation of fluorescence stability and intensity of fluorescamine derivative (Pyrrolinone). ...  Read More

4. SEPARATION OF POLYCYCLIC AROMATIC HYDROCARBONS WITH MIXED MICELLAR HIGH PERFORMANCE LIQUID CHROMATOGRAPHY
Volume 9, Issue 3 , Summer 1998

Abstract
  Separation of Polycyclic Aromatic Hydrocarbons was performed by RP-HPLC using mixed micellar mobile phase. Effect of temperature, types and amounts of coorganic solvent in mobile phase on efficiency, asymmetry factor and selectivity factor showed that the appropriate condition for separation of these ...  Read More

5. SYNTHESES AND ANTIFUNGAL ACTIVITY OF 3-ARYLMETHYL-5-ARYLOXY METHYL-2- METHY LISOXAZOLIDINES
Volume 9, Issue 3 , Summer 1998

Abstract
  Reaction of sodium salt of allyl alcohol with 2-chloro-5-phenyl- l,3,4-thiadiazole gave 2-allyloxy-5-phenyl-1,3,4-thiadiazole 2. Compounds 4a and 4b could be obtained through the reaction of nitrone 3 with 2. Reaction of compound 2 with nitrone 5 afforded the final compound 6. Antifungal activity ...  Read More

6. A CONVENIENT SYNTHESIS OF MACROCYCLIC DIAMIDES
Volume 9, Issue 3 , Summer 1998

Abstract
  Some new macrocyclic dibenzotrioxadiamides, dibenzotetraoxadiamide, dibenzopentaoxadiamide, dibenzothiatrioxadiamide, tribenzotrioxadiamides and tetrabenzohexaoxadiamide (14-21), (26) and (27) have been prepared. These compounds were obtained in the macrocyclization step by reacting the diamine (4) with ...  Read More

7. LIQUEFACTION POTENTIAL ASSESSMENT USING MULTILAYER ARTIFICIAL NEURAL NETWORK
Volume 9, Issue 3 , Summer 1998

Abstract
  In this study, a low-cost, rapid and qualitative evaluation procedure is presented using dynamic pattern recognition analysis to assess liquefaction potential which is useful in the planning, zoning, general hazard assessment, and delineation of areas, Dynamic pattern recognition using neural networks ...  Read More

8. QUASI-PERMUTATION REPRESENTATIONS OF METACYCLIC 2-GROUPS
Volume 9, Issue 3 , Summer 1998

Abstract
  By a quasi-permutation matrix we mean a square matrix over the complex field C with non-negative integral trace. Thus, every permutation matrix over C is a quasipermutation matrix. For a given finite group G, let p(G) denote the minimal degree of a faithful permutation representation of G (or of a faithful ...  Read More

9. PERMUTATION GROUPS WITH BOUNDED MOVEMENT ATTAINING THE BOUNDS FOR ODD PRIMES
Volume 9, Issue 3 , Summer 1998

Abstract
  Let G be a transitive permutation group on a set ? and let m be a positive integer. If no element of G moves any subset of ? by more than m points, then |? | [2mp I (p-1)] wherep is the least odd primedividing |G |. When the bound is attained, we show that | ? | = 2 p q ….. q where ? is a non-negative ...  Read More

10. QUADRATIC STARK CONSTANTS OF NEUTRAL COPPER SPECTRAL LINES IN THE COULOMB APPROXIMATION
Volume 9, Issue 3 , Summer 1998

Abstract
  Quadratic Stark constants of neutral copper spectral lines for all s,p, and d levels are calculated using the Coulomb approximation. These results are compared with existing data and, generally, good agreement is observed  Read More
