An unexpected 1,2-hydride shift in phosphoric acid-promoted cyclodimerization of styrene oxides under solvent-free conditions. A synthetic route towards 2,4-disubstituted 1,3-dioxolanes
(Elsevier Science Ltd, http://www.elsevier.com/locate/tetlet, 2009)
A 1,2-hydride shift in the phosphoric acid-promoted cyclodimerization of styrene oxide and its chloro
derivatives under solvent-free conditions leading to 2,4-disubstituted 1,3-dioxolanes is described. Methoxy substituents ...
Thermal annealing dependence of some physical propertiesof Bi-substituted Sn–Sb–Se glassy thin films
(EDP Sciences, 2009)
Bulk glasses of the Sn10Sb20−xBixSe70 (0 x 8) system were prepared by the conventional
melt quenching technique. Thin films were prepared by the thermal evaporation technique on glass
substrates. Appearance of some ...
On semi-parallel lightlike hypersurfaces of indefinite Kenmotsu manifolds
(Birkhäuser Basel. http://www.springerlink.com/content/107580/?p=1930c3cc1de944feae211b785b3b42a4&pi=0, 2009)
We study semi-parallel lightlike hypersurfaces of an indefinite
Kenmotsu manifold, tangent to the structure vector field. Some Theorems
on parallel and semi-parallel vector field, geodesibility of lightlike
hypersurfaces ...
Prevalence, antimicrobial resistance profiles of Listeria monocytognes from various foods in Gaborone, Botswana
(Academic Journals, http://www.academicjournals.org/AJB, 2009)
Listeria monocytogenes is known to cause epidemic and sporadic cases of listeriosis. The present study investigated the occurrence, antibiograms and molecular serotypes of the organism in various retail outlets in Gaborone, ...
Comparative assessment of water infiltration of soils under different tillage systems in eastern Botswana
(Elsevier Science Ltd, http://www.elsevier.com/locate/pce, 2009)
Water infiltration is an important component of water balance for improving crop production potential in
dryland soil tillage systems in Botswana, particularly in the eastern region. Hardsetting soils common in arable ...
