Polarizing microscopic and 31P NMR studies of decylammonium chloride/potassium chloride/water system. containing phosphoric acid monodecyl ester and H3PO4
(Marcel Dekker Inc, 1995)The decylammonium chloride (DACl), KCl and D2O system forms two phases(N-c+N-d) in the nematic range. The N-d phase was ca. 15% by volume and exhibited extinct appearance. From conoscopic measurements it was inferred that ... -
1,3-Dipolar cycloaddition reactions of some 3-aryl-phthalazinium-1-olates, part II
(Soc Chimique Belgique, 1995)Reactions of some new 3-aryl-phthalazinium-1-olates were studied with olefinic and acetylenic dipolarophiles giving the expected cycloadducts. However, the cycloaddition of 3-(4',6'-dimethylpyrimidin-2'-yl)-phthalazinium-1-olate ... -
Succession of the low temperature phase transitions in TlInS2 crystals
(Pergamon-Elsevier Science Ltd, 1995)Two additional incommensurate phase transitions (PT's) at Ti = 206 K and T-tr = 79 K were observed in TlInS2 crystals. Peculiarities of the temperature behaviour of the dielectric susceptibility and the dielectric loops ... -
Preparation and characterization of perlite-filled highdensity polyethylenes . III. impact properties
(John Wiley & Sons Inc, 1995)Impact properties of perlite-filled high-density polyethylene (HDPE) composites were studied with the Charpy method by using both notched and unnotched samples. gamma-Aminopropyltriethoxy silane (gamma-APS, A-1100) was ... -
Relationship between theoretically calculated lumo energies and cathodic peak potentials of some 2-benzylbenzoxazole derivatives
(Soc Chimique Belgique, 1996)Cathodic peak potentials of various bioactive 2-benzylbenzoxazole derivatives were measured by cyclicvoltammetry and correlated with the lowest unoccupied molecular orbital calculated at the level of Extended Huckel molecular ... -
Electron-fluid model for DC size effect under a magnetic field
(Akademie Verlag Gmbh, 1996)The collective motion of conduction electrons, which are treated as a fluid, is described by the Navier-Stokes and Maxwell equations. The presence of electric and magnetic fields is accounted for and Ohm's law is generalized. ... -
Composition of tars from softwoods and birch

Chain-extended bismaleimides .1. a study of chain-extended bismaleimides as matrix elements in carbon fiber composites
(John Wiley & Sons Inc, 1996)A series of chain-extended bismaleimide resins as matrix elements in carbon fibers were cured and characterized in terms of their thermal and thermomechanical properties. The cured resins were stable up to 430 degrees C ... -
Chemical constituents of balsam from liquidambar orientalis
(Walter De Gruyter & Co, 1996)The species of Liquidambar, an important genus ofHamamelidaceae family, are known for their bal-samic exudations. Liquidambar orientalis Mill, oc-curs in Asia Minor, Liquidambar styraciflua L. ... -
Chain-extended bismaleimides .1. preparation and characterization of maleimide-terminated resins
(John Wiley & Sons Inc, 1996)Starting from aromatic diamines, a series of bismaleimides (BMIs) and maleimide-terminated structural resins were prepared in solution and characterized. Maleimide-terminated resins were prepared through Michael addition ... -
Some properties of cyclacenes and silacyclacenes
(Comite Van Beheer Van Het Bulletin Vzw, 1997)Various Huckel type cyclacenes and silacyclacenes are subject to semi-empirical molecular orbital treatment at the level of AMI type. Cyclacenes having silicon atom at the peri and fusion points of arenoid rings as well ... -
On several types of compactness in smooth topological spaces
(Elsevier Science Bv, 1997)The smooth closure and smooth interior of a fuzzy set w.r.t. a smooth topology were defined by Gayyar et al. (1994), and some relations between a few types of compactness were established in the presence of strong restrictions. ... -
Neighborhood structures of smooth topological spaces
(Elsevier Science Bv, 1997)Smooth topological spaces and their fundamental concepts have been discussed in the literature [2, 4-7]. In this paper, we present the notions of base and two sorts of neighborhood structure of smooth topological spaces ... -
GCR1-dependent transcriptional activation of yeast retrotransposon Ty2-917
(John Wiley & Sons Ltd, 1997)Transcription of Saccharomyces cerevisiae Ty2-917 retrotransposon depends on regulatory elements both upstream and downstream of the transcription initiation site. An upstream activation sequence (UAS) and a downstream ... -
