Development of phoma lesions on oilseed rape leaves inoculated with ascospores of A-group or B-group Leptosphaeria maculans (stem canker) at different temperatures and wetness durations
(2001-02)In controlled-environment experiments, ascospores of both A-group and B-group Leptosphaeria maculans were able to infect leaves of oilseed rape and produce phoma leaf spot lesions at temperatures from 5 to 20 degreesC and ... -
Turbidimetric and HPLC assays for the determination of formulated lysozyme activity
(2001-04)In several studies lysozyme has been employed as a model protein to investigate the effects of formulation factors upon biological activity. The aim of this work was to develop and validate an HPLC technique to assay ... -
End point of the rp process on accreting neutron stars
(2001-04-16)We calculate the rapid proton (rp) capture process of hydrogen burning on the surface of an accreting neutron star with an updated reaction network that extends up to Xe, far beyond previous work. In both steady-state ... -
Measurement of the (gamma,n) reaction rates of the nuclides Pt-190, Pt-192, and Pt-198 in the astrophysical gamma process
(2001-05)The nucleosynthesis of heavy neutron-deficient nuclei in a stellar photon bath at the temperatures relevant for the astrophysical gamma process was investigated. In order to derive (gamma ,n) cross sections and reaction ... -
Bessel–Gauss beam optical resonator
(2001-04-01)In a simple picture, a Bessel beam is views as a transverse standing wave formed in the interference region between incoming and outgoing conical waves. Bases on this interpretation we porpose an optical resonator that ... -
Activation of clindamycin phosphate by human skin
(2001-04)Aims: To investigate the relative antimicrobial activity of clindamycin phosphate (CP) and clindamycin (Cly) and to examine the effect of skin homogenates on the activity of CP. Methods and Results: Minimum inhibitory ... -
The endpoint of the rp-process on accreting neutron stars
(2001-05-21)We find that the rp process in X-ray bursts and in steady state burning, for example in X-ray pulsars, ends in a SnSbTe cycle. We discuss the consequences for the neutron star crust composition an X-ray burst light curves. -
Proton capture cross section of Sr isotopes
(2001-05-21)The (p,gamma) cross section of Sr-84,Sr-86,Sr-87 isotopes has been measured using activation technique in the proton energy range between 1.5 and 3 MeV. These reactions are relevant to the p-process of stellar nucleosynthesis ... -
Nucleosynthesis in massive stars revisited
(2001-05-21)We have performed the first calculations to follow the evolution of all stable nuclei and their radioactive progenitors in a finely-zoned stellar model computed from the onset of central hydrogen burning through explosion ... -
Improving explosive nucleosynthesis models via (n,alpha) measurements
(2001-05-21)In explosive environments, (gamma,alpha) reactions constitute some of the most important links in the nucleosynthesis chains. However. it is very unlikely that the rates for most of these reactions will be determined by ... -

Tables of nuclear cross sections and reaction rates : An addendum to the paper "Astrophysical reaction rates from statistical model calculations"
(2001-09)In a previous publication (ATOMIC DATA AND NUCLEAR DATA TABLES 75, 1 (2000)), we gave seven-parameter analytical fits to theoretical reaction rates derived from nuclear cross sections calculated in the statistical model ... -
Fructosamine concentration and resistance to natural, predominantly Teladorsagia circumcincta infection
(2001-08)Fructosamine con cent rations reflect protein status and because infection with Teladorsagia circumcineta can induce a relative protein deficiency, we examined the usefulness of fructosamine concentrations as markers of ... -
Development of Pyrenopeziza brassicae apothecia on agar and oilseed rape debris
(2001-06)The development of apothecia of Pyrenopeziza brassicae (anamorph Cylindrosporium concentricum) on oilseed rape debris and compost malt agar was observed by scanning electron and light microscopy. On oilseed rape debris, ... -
Methods for integrated air sampling and DNA analysis for detection of airborne fungal spores
(2001-06)Integrated air sampling and PCR-based methods for detecting airborne fungal spores, using Penicillium roqueforti as a model fungus, are described, P, roqueforti spores were collected directly into Eppendorf tubes using a ... -

Factors affecting the incubation period of dark leaf and pod spot (Alternaria brassicae) on oilseed rape (Brassica napus)
(1996-07)Experiments to investigate the factors affecting the incubation period of dark leaf and pod spot (Alternaria brassicae) on leaves and pods of oilseed rape (Brassica napus) were done in controled environment (constant ... -
Comparison of two sympatric Pasteuria populations isolated from a tropical vertisol soil
(1996-07)An isolate of Pasteuria (designated PPMJ) recovered from the root-knot nematode Meloidogyne javanica, was characterized using host preference, spore morphometrics, and serology, and compared with another sympatric Pasteuria ... -
Identification of the root-knot nematode, Meloidogyne incognita, using monoclonal antibodies raised to non-specific esterases
(1996-08)The esterase isozyme from Meloidogyne incognita with pI similar to 4.95 was purified using a Rotofor electrophoresis system. The purified enzyme was then used to raise monoclonal antibodies. Hybridoma cell lines producing ... -
The role of ventral tegmental dopamine neurons in locomotor sensitization following quinpirole or (+)-amphetamine : Ex vivo voltammetric evidence
(1996-12)Behavioural sensitization to the locomotor stimulating effects of (+)-amphetamine or quinpirole was induced in rats by intermittent drug administration. Following expression of sensitization, locomotor activity scores on ...
