Effects of temperature and wetness duration on conidial infection, latent period and asexual sporulation of Pyrenopeziza brassicae on leaves of oilseed rape
(2000-08)Experiments in controlled environments were carried out to determine the effects of temperature and leaf wetness duration on infection of oilseed rape leaves by conidia of the light leaf spot pathogen, Pyrenopeziza brassicae. ... -
Effects of stem canker (Leptosphaeria maculans) and light leaf spot (Pyrenopeziza brassicae) on yield of winter oilseed rape (Brassica napus) in southern England
(2000-08)The relationships between yield loss and incidence or severity of stem canker and light leaf spot in winter oilseed rape were analysed by correlation and regression analyses, using data from experiments at Rothamsted, ... -
Direct effects of 3,4-methylenedioxymethamphetamine (MDMA) on serotonin or dopamine release and uptake in the caudate putamen, nucleus accumbens, substantia nigra pars reticulate, and the dorsal raphe nucleus slices
(2000-06-15)We examined the effects of pressure ejected 3,4-methylenedioxymethamphetamine (MDMA) from a micropipette on direct chemically stimulated release, and on electrically stimulated serotonin (5-HT) or dopamine (DA) release in ... -
The electrostability and electrically assisted delivery of an organophosphate pretreatment (physostigmine) across human skin in vitro
(2000-08-10)Physostigmine is a tertiary carbamate that is utilised as a pretreatment against organophosphate intoxication. Oral delivery of physostigmine is not practical due to high first pass metabolism and short Elimination half ... -
Neutron cross sections for nucleosynthesis studies
(2000-09)Previous compilations of (n, gamma) cross sections of relevance for neutron capture nucleosynthesis in the big bang and in the slow neutron capture process (s process) have been updated to encompass information available ... -
Epidemiology in relation to methods for forecasting light leaf spot (Pyrenopeziza brassicae) severity on winter oilseed rape (Brassica napus) in the UK
(2000-09)Pyrenopeziza brassicae, cause of light leaf spot of oilseed rape, has a complex polycyclic life cycle. It can be difficult to control light leaf spot in winter oilseed rape in the UK since it is not easy to optimise fungicide ... -
Sm-147(n,alpha) cross section measurements from 3 eV to 500 keV : Implications for explosive nucleosynthesis reaction rates
(2000-10)We have measured the Sm-147(n, alpha) cross section from 3 eV to 500 keV. These data were used to test nuclear statistical models which must be relied on to calculate the rates for as yet unmeasurable reactions occurring ... -
High-resolution neutron capture and transmission measurements, and the stellar neutron-capture cross section of Sr-88
(2000-11)We have made new and improved measurements of the neutron capture and total cross sections for Sr-88 at the Oak Ridge Electron Linear Accelerator (ORELA). Improvements over previous measurements include a wider incident ... -
Relationships between phoma leaf spot and development of stem canker (Leptosphaeria maculans) on winter oilseed rape (Brassica napus) in southern England
(2000-10)Models were constructed to describe the relationships between incidence of phoma leaf spot at different growth stages in autumn/winter or early spring and incidence of stem canker (basal canker or stem lesions) in summer ... -
Mitigation of surfactant erythrocyte toxicity by egg phosphatidylcholine
(2000-10)Polyoxyethylene alkyl ether surfactants have been shown to have excellent penetration enhancing abilities although they are associated with a high level of local toxicity. We have compared the toxicity of a range of ... -
The effects of high salinity (NaCl) and supplementary phosphorus and potassium on physiology and nutrition development of spinach
(2001)An outdoor pot experiment was carried out in sand culture to investigate the response of spinach (Spinacia oleracea ) cv. “Matador” grown at high salinity to supplementary phosphorus and potassium. Plants were tested during ... -
The influence of water deficit on vegetative growth, physiology, fruit yield and quality in eggplants
(2001)The effects of water deficit on plant growth, physiology and dry matter accumulation in the eggplant (Solanum melongena L. cv., Teorem F1) grown in pot were studied under out door conditions. Water stress was imposed by ... -
The influence of relative resistance and urea-supplementation on deliberate infection with<i> Teladorsagia circumcincta during winter
(2000-12-20)The consequences for lambs of infection over the winter with Teladorsagia circumcincta were quantified by deliberate, trickle infection of selected animals at 7 months of age. Infected and control uninfected animals were ... -
The roles of ascospores and conidia of Pyrenopeziza brassicae in light leaf spot epidemics on winter oilseed rape (Brassica napus) in the UK
(2001)Ascospores of Pyrenopeziza brassicae were produced in apothecia (cup-shaped ascomata) on oilseed rape debris. The conidia, which were morphologically identical to the ascospores, were produced in acervular conidiomata on ... -
Squeezing and temperature measurement in Bose-Einstein condensates
(2001)In this paper we review recent developments in the theory of quasi-particle coupling in trapped Bose–Einstein condensates. We discuss prospects for observing squeezed quasi-particles in finite-temperature condensates. -
Responses of tomato CVs grown to fruit-harvest stage under zinc stress in glasshouse conditions
(2001)A glasshouse pot experiment, with three tomato cultivars (CVs), Blizzard, Calypso, and Liberto, was carried out to investigate the effects of three levels of Zn (0.01, 0.5, and 30 mg L-1), supplied in nutrient solution, ... -

Factors affecting development of phoma canker (Leptosphaeria maculans) on stems of winter oilseed rape (Brassica napus) in southern England
(2001)In winter oilseed rape experiments at Rothamsted in 1997/98 (cvs Lipton and Capitol), 1998/99 (cv. Apex) and 1999/2000 (cvs Apex, Lipton and Capitol), development of crown canker and phoma stem lesions in spring was related ... -
Opto-thermal measurement of barrier cream residence time on skin in-vivo
(2001)We report the non-invasive opto-thermal measurement of the residence time of a barrier cream on in-vivo skin. These measurements revealed an approximately exponential decrease of cream layer thickness with a 1/e disappearance ...
