1. CONIDIAL DISTRIBUTION OF FRESHWATER HYPHOMYCETES OF AN IRANIAN RIVER: ZAYANDE-ROUD
Volume 4, Issue 3 , Summer 1993
Abstract
There is no published report regarding Iran's aquatic hyphomycetes. In an attempt to identify species of aquatic hyphomycetes in a river in central Iran (Zayande-Roud River), conidial frequency and distribution were determined by filtration. Water samples were collected monthly from two stations 55 km ... Read More2. THE CHINKARA (GAZELLA BENNETTI) IN IRAN, WITH THE DESCRIPTION OF TWO NEW SUBSPECIES
Volume 4, Issue 3 , Summer 1993
Abstract
The distribution of Gazella bennetti in Iran is reviewed. The species is commonly said to be confined to the southeastern part of the country, but is actually widespread over suitable areas, east of the Zagros Range and south of the Alborz. In the north and west of this range, there is a hitherto undescribed ... Read More3. Co(II) AND Cu(II) - PROMOTED BASE HYDROLYSIS OF 2-CYANO-l, lO-PHENANTHROLINE
Volume 4, Issue 3 , Summer 1993
Abstract
Co(II) and Cu(II) promoted base hydrolysis of 2-cyano, 1, lO-phenanthroline was studied. At 298.2°K, Cu(II) reaction is more efficient (by a factor of 20) than either Co(ll) and its analogues Ni(II) in promoting base hydrolysis. Read More4. A STUDY OF THE SILYLATION REACTION OF IMINES WITH TRIMETHYLCHLOROSILANE IN THE PRESENCE OF LITHIUM
Volume 4, Issue 3 , Summer 1993
Abstract
A mixture oftrimethylchlorosilane (TMS-Cl), lithium and tetrahydrofuran (THF) reacts with imines to produce disilyl compound by addition of two trimethylsilyl (TMS) groups to the double bond of the imine. On hydrolysis the TMS on nitrogen is substituted by hydrogen and yields ? -silylamine. In the presence ... Read More5. ONE STEP SYNTHESIS OF ANILINO ALKYL-NSUBSTITUTED PHTHALIMIDES RELATED TO BENZOISOQUINOLINE-1,3-DIONES (1)
Volume 4, Issue 3 , Summer 1993
Abstract
A facile one step synthesis of anilino alky1-N-substituted phthalimide I is reported. The following compounds belonging to this series were made: 1. (anilino-N-ethyl) phthalimide 8 2. (3,4, 5-trimethoxy anilino-N-ethyl) phthalimide 6 3. (3,4, 5-trimethoxy anilino-N-propyl) phthalimide 7 4. N-(ethyl ... Read More6. AN APPROACH TO THE A RING OF VITAMIN D ANALOGUES VIA SEQUENTIAL CARBOMETALATION/ ANION CAPTURE
Volume 4, Issue 3 , Summer 1993
Abstract
An intramolecular palladium catalysed carbometalation followed by anion capture achieves construction of a model comprised of the A ring of Vitamin D oxygen analogues. Read More7. A CONVENIENT METHOD FOR PREPARATION AND ISOLATION OF 4-n PROPYL-I ,2,4TRIAZOLINE- 3,5-DIONE
Volume 4, Issue 3 , Summer 1993
Abstract
4-n- prophyl- 1,2,4- triazoline-3-5- dione was synthesized from n-propylisocyanate and ethylhydrazine carboxylate in several steps. The title compound was isolated as pink crystals in high yield and purity. This compound was fully characterized by IR and H-NMR spectroscopy Read More8. PYRAZOLINES AND ISOXAZOLINES (I). SYNTHESIS AND ANTIMICROBIAL ACTIVITIES OF P-(1-ACYL-3-METHYL-5-ARYL-4 PYRAZOLINOYL / P-(3-METHYL-5-ARYL-4ISOXAZOLINOYL) ARSANILIC ACID
Volume 4, Issue 3 , Summer 1993
Abstract
4-(acetoacetamido) arsanilic acid (II), which was then condensed with aryl aldehydes. The resulting product on reaction with hydrazine hydrate and hydroxyl amine hydrochloride yielded Pyrazolines (IV) and Isoxazolines (V), respectively. The antimicrobial activity of compounds against a number of microorganisms ... Read More9. A NEW SPECIES OF HETEROSTEGINA IN MIDDLE PALEOCENE FROM THE KHUZESTAN AREA (S.W. IRAN)
Volume 4, Issue 3 , Summer 1993
Abstract
New evidence gained by the study of Foraminifera from Khuzestan province in southwest Iran reveals that the basal limit of the genus Heterostegina is not restricted to the Eocene epoch. By introducing a new species of this genus (H. rezvaninejadi), this study shows that the early appearance of this ... Read More10. SOME RESULTS OF CONTINUITY ?f
Volume 4, Issue 3 , Summer 1993
Abstract
The dynamical behavior of a map on the unit interval has been the subject of much contemporary research. In this paper, we will consider the relation between the continuity of the map cof and cof for some positive integer k, where f is a continuous map from the unit interval to itself, and ?f is a ...

Volume 4, Issue 3 , Summer 1993
Abstract
In a commutative Noetherian local complex normed algebra which is complete in its M-adic metric there are only finitely many closed prime ideals. Read More12. A COMMUTATIVITY CONDITION FOR RINGS
Volume 4, Issue 3 , Summer 1993
Abstract
In this paper, we use the structure theory to prove an analog to a well-known theorem of Herstein as follows: Let R be a ring with center C such that for all x,y ? R either [x,y]= 0 or x-x [x,y]? C for some non negative integer n= n(x,y) dependingon x and y. Then R is commutative. Read More13. ESTIMATION OF RADIATION LOSS FROM STELLARATORS USING NEOCLASSICAL TRANSPORT THEORY
Volume 4, Issue 3 , Summer 1993
Abstract
The radiation power loss from a magnetically confined plasma in a stellarator has been calculated using neoclassical particle and energy fluxes in an energy balance equation. We could obtain a power loss of about 34% of the total input power by numerical calculation. This fraction of the power loss ... Read More14. MULTIHADRON PRODUCTION FOR e e FOR FROM 50 TO 61 GeV, C.
