The infection rate of an established colony of Culicoides variipennis to oral infection with bluetongue virus (BTV) type 4 was found to be highly variable and ranged from 0 to 51.6 per cent. This type of wide variation has previously only been report

The acute single dose oral toxicity of carbophenothion (S-4-chlorophenylthiomethyl OO-diethyl phosphorodithioate) has been determined in Canada geese (Branta canadensis), pigeons (Columba livia) and Japanese quail (Coturnix coturnix japonica). At pos

A fast night-sky Cerenkov detector has been used in a search for γ-rays of energy 1012 eV from ten pulsars. Observations were made at a site in Malta during the years 1969–70. No strong evidence for continuous emission was found, and the upper flu

The design objectives of real-time operating systems for minicomputers are considered. Simplicity, efficency and avoidance of superfluities are the main criteria. A typical multitasking structure is sketched and the executive elements to support it a

An investigation into the poisoning of birds with 1,1,1-trichloro-2, 2-di (4-chlorophenyl) ethane (DDT) on a fruit farm in South-East England is described. Pesticide levels in wild birds were sufficient to be held responsible for deaths. It is sugges

Following the deaths of blackbirds in 1971 and 1972 an investigation was mounted into the comparative levels of DDT and its metabolites in soil, earthworms, moles, birds and their eggs in a small orchard in East Anglia. The build up of residues in th

The acute oral toxicity of chlorfenvinphos [2-chloro-1-(2′, 4′-dichlorophenyl)vinyl diethyl phosphate] was measured in pigeon (Columba livia), pheasant (Phasianus colchicus), and quail (Coturnix coturnix japonica) and the compound was shown to be
The rotor subsystem represents one of the major cost drivers in conventional wind energy systems. Despite the fact that the two vortex extraction systems evaluated have the potential for substantially reducing rotor costs, these cost savings are more

SummaryInfection of domestic ruminants with bluetongue virus (BTV) is widespread in the Sudan but there are no records of vector species of Culicoides in that country. Therefore, light-trap collections of Culicoides for virus isolation procedures wer
