Simultaneous double 1,3-dipolar cycloaddition reactions involving bisnitrones or bisdipolarophiles. 1h nmr investigation of the conformational preferences of n-methyl- and n-phenyl-isoxazolidines
(Royal Society of Chemistry (RSC), 2001-01-01)Binitrones 1a and 1b reacted with N-methylmaleimide giving bisisoxazolidines. Diastereospecific reaction of the phenyl substituted dipole 1a gave 3a whilst the N-methyl dipole 1b furnished diastereomeric adducts 3b, 4 and ... -
Simultaneous expression of type 1 and type 2 lewis blood group antigens byhelicobacter pylorilipopolysaccharides
(American Society for Biochemistry & Molecular Biology (ASBMB), 1998-05-08)Previous structural investigations performed on the lipopolysaccharides (LPSs) from the human gastric pathogen Helicobacter pylori have revealed that these cell surface glycan molecules express type 2 partially fucosylated, ... -
Simultaneous photometry and echelle spectroscopy of the dwarf nova bz ursae majoris during the 2005 january outburst
(Oxford University Press (OUP), 2006-05-08)We report simultaneous photometric and echelle-spectroscopic observations of the dwarf nova BZ UMa during which we were lucky to catch the system at the onset of an outburst, the development of which we traced in detail ... -
Simultaneous x-ray and t[clc]e[/clc]v observations of a rapid flare from markarian 421
(IOP Publishing, 1999-12-01)Mrk 421 was observed for about 2 days with BeppoSAX in 1998 April as part of a worldwide multiwavelength campaign. A large, well-defined flare was observed in X-rays. The same flare was observed simultaneously at TeV ... -

Singular differential equations with linear and nonlinear boundary conditions
(Elsevier BV, 1998-02-01)Existence results are established for the singular equation y " + f(t, y) = 0, where f is not a Caratheodory function. Our nonlinearity f is allowed to change sign. -
Singular dirichlet boundary value problems ii: resonance case
(Institute of Mathematics, Czech Academy of Sciences, 1998-06-01)Existence results are established for the resonant problem y " + lambda(m) a y = f(t, y) a.e. on [0, 1] with y satisfying Dirichlet boundary conditions. The problem is singular since f is a Caratheodory function, a ... -

Singular positone and semipositone boundary value problems of second order delay differential equations
(Institute of Mathematics, Czech Academy of Sciences, 2005-06-01)In this paper we present some new existence results for singular positone and semipositone boundary value problems of second order delay differential equations. Throughout our nonlinearity may be singular in its dependent ... -
Singular problems modelling phenomena in the theory of pseudoplastic fluids
(Cambridge University Press (CUP), 2003-10-01)Existence criteria are presented for nonlinear singular initial and boundary value problems. In particular our theory includes a problem arising in the theory of pseudoplastic fluids. -

Sister chromatid cohesion and genome stability in vertebrate cells
(Portland Press Ltd., 2003-02-01)For successful eukaryotic mitosis, sister chromatid pairs remain linked after replication until their kinetochores have been attached to opposite spindle poles by microtubules. This linkage is broken at the metaphase-anaphase ... -
Site selectivity in the addition of ketoximes to activated allenes and alkynes; n- versus o-alkylation
(Royal Society of Chemistry (RSC), 1999-01-01)Reaction of ketoximes with methyl propiolate afforded geometrical isomers of the methyl 3-(hydroxyimino)propanoates 4 and of the O-vinyl oximes 5 as well as the 2-isoxazoline 6. With dimethyl penta-2,3-diendioate 8c reaction ... -

Small cell neuroendocrine carcinoma of the breast: a report of three cases and review of the literature
(BMJ, 2005-07-01)Small cell neuroendocrine carcinoma of the breast is a rare tumour with less than 30 cases reported in the literature. The clinicopathological findings of three cases of primary neuroendocrine carcinoma of the breast and ... -
Small subunit rrna gene sequences of aeromonas salmonicida subsp. smithia and haemophilus piscium reveal pronounced similarities with a. salmonicida subsp. salmonicida
(Inter-Research Science Center, 1999-01-01)The small subunit ribosomal RNA (SSU rRNA) encoding genes from reference strains of Aeromonas salmonicida subsp, smithia and Haemophilus piscium were amplified by polymerase chain reaction and cloned into Escherichia coli ... -
Smyth surfaces and the drehriss
(Cambridge University Press (CUP), 2005-09-15)Isometric deformations of immersed surfaces in Euclidean 3-space are studied by means of the drehriss. When the immersion is of constant mean curvature and the deformation preserves the mean curvature, we determine the ...
