Volume 1, Issue 4 , Summer 1990

Abstract
  The binding of Sodium n-dodecyl sulphate (SDS) to histone H3 was studied in the pH range 3.2-10 by equilibrium dialysis at 27? and 3 7 ?c .T he binding data have been used to obtain the Gibbs free energy of interaction using a theoretical model of the Wyman binding potential; and the enthalpy of interaction ...  Read More

2. THE INFLUENCE OF CHARGE DENSITY ON THE INTERACTION BETWEEN SODIUM NDUDECYL SULPHATE (SDS) WITH H1
Volume 1, Issue 4 , Summer 1990

Abstract
  The binding data for the interaction of SDS with HI, in aqueous solution at various ionic strengths have been measured by equlibrium dialysis, and investigated spectroscapicaliy. The effect of charge density on the interaction is shown to be of considerable interest. The presence of NaCl causes conformational ...  Read More

3. A QUANTUM CHEMICAL STUDY OF STRUCTURE -ACTIVITY RELATIONSHIPS OF DIHYDROPYRIDINE CALCIUM ANTAGONISTS
Volume 1, Issue 4 , Summer 1990

Abstract
  Quantum chemical (MNDo)caleulations have beenused toelucidate the molecular properties and structure - activity relationships of dihydropyridine (DHP) type calcium antagonists. There is a good corielation between the net atomic charges on various atoms of the 4 - phenyl ring of dihydropyridines and ...  Read More

4. SPECTROPHOTOMETRIC DETERMI NATION OF OSMIUM (VIII) WITH 1-HYDROXY 2- PYRIDINE - THIONE (SODIUM SALT) AS A REAGENT
Volume 1, Issue 4 , Summer 1990

Abstract
  A spectrophotometric study of osmium (VIII) complex of 1-hydroxy 2- pyridine thione (HPT) is presented. A red-violet complex, 0 s (HPT) is formed in a highly acidic solution, and shows maximum absorbance at 500 nm with molar absorptivity of 5.12 x 101. mol . cm . Beer's law is obeyed in the range ...  Read More

5. SYNTHESIS AND SPECTROSCOPIC STUDIES OF THIOCYANATO -DERIVATIVES OF CU-Mo-S CLUSTERS
Volume 1, Issue 4 , Summer 1990

Abstract
  The complexes [MoS (CUNCS) ] w hen x = 2,3,4 and [MoOS , (CUNCS) ] when y = 2, 3 have been prepared by the reaction of CuSCN with [P(C H ) ] [MoS ] or [P(C H ) ] [MOOS ] in dry degassed acetone or DMFsolution and recrystallized from dichloromethane, the attempted preparation of [MoS (AgSCN) ...  Read More

6. REACTION OF TRIMETHYLCHLOROSILANE WITH EPOXYKETONES IN THE PRESENCE OF MAGNESIUM
Volume 1, Issue 4 , Summer 1990

Abstract
  Mixture of the trimethylchlorosilane, magnesium and hexamethylphosphorictriamid, HMPT, react with epoxyketones to produce tetrasiliciated compounds, which are the results of the addition of two trimethylsilyl (TMS) groups to the carbonyl function and two TMS groups to the expoxide cycle. After elimination ...  Read More

Abstract
  The syntheses of the title compounds are described. 1- [[2- Amino -1 - (hydroxymethyl) ethoxy] methyl] uracil exhibitslittleactivity against herpesviruses (HSV) in vivo  Read More

8. DEUTERIUM STUDIES IN THE DISPROPORTIONATION OF THIOXANTHYLIUM SALTS
Volume 1, Issue 4 , Summer 1990

Abstract
  Deuterium labelling is used to show that the disproportionation of thioxanthylium salts involve transfer of a hydride, (deuteride) ion from the9-positionof one molecule of the compound, as its hydro], to the 9 - position of another molecule in the cation form  Read More

9. SELENIUM HETEROCYCLES XXXX [I] SYNTHESES OF 4- (2-PYRAZINYL) - 1, 2, 3: SELENADIAZOLE AND 4- (2-PYRAZILYL)' - l,2,3- THIADIAZOLE

11. A CHARACTERIZATION OF EXTREMELY AMENABLE SEMIGROUPS
Volume 1, Issue 4 , Summer 1990

Abstract
  Let S be a discrete semigroup, m (S) the space of all bounded real functions on S with the usualsupremum norm. Let Acm (S) be a uniformly closed left invariant subalgebra of m (S) with 1 c A. We say that A is extremely left amenable if there isamultiplicative left invariant meanon A. Let P = {h ?A: ...  Read More

12. BAYES ESTIMATION USING A LINEX LOSS FUNCTION
