1. STUDIES ON THE CARYOLOGY OF SOME SPECIES OF THE GENUS SUAEDA (CHENOPODIACEAE) IN IRAN
Volume 5, Issue 2 , Summer 1994

Abstract
  Caryological studies were carried out on ten species of the genus Suaeda belonging to 27 samples of different populations in Iran. Important chromosome features including numbers, lengths, centromere locations and caryotypes were studied. All the species have basic chromosome numbers of x=9. Chromosome ...  Read More

2. IN VITRO STUDY OF AN ENDOGENOUS IMMUNOSUPPRESSOR FACTOR DERIVED FROM HUMAN OR BOVINE SERUM
Volume 5, Issue 2 , Summer 1994

Abstract
  The effects of the human and bovine LSF (derived from sera) as well as their purified fractions were studied on murine lymphocytes reactions indicated by blast transformation (BT) assay, mixed lymphocyte culture (MLC) and IgG synthesis. The results indicated that bovine lipid suppressor factor (LSF) ...  Read More

3. PREPARATION AND ISOMERIZATION OF DICHLOROAMINO-3,5-DIFLUORORO-4- HEPTAFLUOROISOPROPYL-6-METHOXY PYRIDINE
Volume 5, Issue 2 , Summer 1994

Abstract
  Treatment of 4-heptafluoroisopropyl-2-methoxy-3,5,6-trifluropyridine (4 ) with aqueous ammonia in THF gave 2-amino-3,5-difluoro-4-heptafluoroisopropyl- 6-methoxy pyridine (5) in 7 1% yield. Chlorination of this amine with 'ButOCl at -16°C gave an unstable product, namely 2-dichloroarnino-3,5- difluoro-4-heptafluoroisopropyl-6-methoxy ...  Read More

4. UPPER DEVONIAN ACRITARCHS AND MIOSPORES FROM THE GEIRUD FORMATION IN CENTRAL ALBORZ RANGE, NORTHERN IRAN
Volume 5, Issue 2 , Summer 1994

Abstract
  The Geirud Formation consists mainly of clastic sediments which are interbedded with limestone stringers. This rock unit is well-exposed along the Central Alborz Range in northern Iran. The Geirud Formation rests unconformably on the Mila Formation (Upper Cambrian) and is conformably overlain by ...  Read More

5. THE INTERNAL IDEAL LATTICE IN THE TOPOS OF M-SETS
Volume 5, Issue 2 , Summer 1994

Abstract
  We believe that the study of the notions of universal algebra modelled in an arbitarry topos rather than in the category of sets provides a deeper understanding of the real features of the algebraic notions. [2], [3], [4], [S], [6], [7], [13], [14] are some examples of this approach. The lattice Id(L) ...  Read More

6. B -AND B - COMPLETENESS IN LOCALLY CONVEX ALGEBRAS AND THE E x THEOREM
Volume 5, Issue 2 , Summer 1994

Abstract
  Let E be a B-complete (B -complete) locally convex algebra and $ the topological direct sum of countably many copies of the scalar field with a jointly continuous algebra multiplication. It has been shown that E is also B-complete (B -complete) for componentwise multiplication on E . B-and Br-completeness ...  Read More

7. OPTICAL ABSORPTION IN Ce0 -V 0 EVAPORATE THIN FILMS
Volume 5, Issue 2 , Summer 1994

Abstract
  In this work, the optical absorption near the fundamental absorption edge of co-evaporated Ce0 -V20 films is studied. It is found that the fundamental optical absorption in these materials is sharp more like that expected for crystals. It is also found that as the V O content increases, the edge ...  Read More
