Farm-level assessment of the nutrient balance in northern Nigeria.
The farming system of the Kano close-settled zone, northern Nigeria, is known for its longevity and continued productivity in spite of population increases in the area. Mounting circumstantial evidence has led to its ...
Differential release of dopamine by nitric oxide in subregions of rat caudate putamen slices
Fast cyclic voltammetry was used to measure NO and dopamine (DA) simultaneously in rat caudate putamen (CPu) slices. Analysis of electrochemical signals obtained from mixtures of DA and NO showed that subtraction of either ...
The primacy model: A new model of immediate serial recall
A new model of immediate serial recall is presented: the primacy model. The primacy model stores order information by means of the assumption that the strength of activation of successive list items decreases across list ...
Incorporation of the acetylcholine receptor dimer from Torpedo californica in a peptide supported lipid membrane investigated by surface plasmon and fluorescence spectroscopy
The dimer species (M-r 580 000) of the nicotinic acetylcholine receptor, isolated from the electric organ of Torpedo californica, was incorporated into a thiopeptide supported lipid bilayer. The incorporation was achieved ...
Analysis of ribosomal DNA sequences of Polymyxa species and related fungi and the development of genus- and species-specific PCR primers
A region of about 800 bp of ribosomal DNA has been sequenced in 10 isolates of Polymyxa and one isolate each of Plasmodiophora brassicae and the chytrid Olpidium brassicae. This region consists of about 330 bp at the 3' ...
Effects of light leaf spot (Pyrenopeziza brassicae) on yield of winter oilseed rape (Brassica napus)
The relationship between development of light leaf spot and yield loss in winter oilseed rape was analysed, initially using data from three experiments at sites near Aberdeen in Scotland in the seasons 1991/92, 1992/93 and ...
The role of the general practitioner in the community care of people with HIV infection and AIDS : a comparative study of high- and low-prevalence areas in England
Background. Policy for the care of people suffering from HIV and AIDS has changed over the past decade. Schemes for shared primary and secondary care have been met with varying success, and patients may be reluctant to ...
An observational study of prescribing and administration of intravenous drugs in a general hospital
The prescribing and administration of intravenous drugs on two surgical and one medical ward were studied to determine the number, type and causes of errors occurring. The errors were classified for potential to harm the ...
