Personal construct psychotherapy has rarely been applied to sexual disorders. In this paper a constructivist approach is contrasted with alternative methods of treating such problems on three related dimensions concerning ...
EXO 023432-5232.3 - an eclipsing AM Herculis binary
(1988)
The authors report observations of the serendipitous EXOSAT source EXO 023432-5232.3 which confirm that the object is an AM Herculis type binary and show the presence of eclipses by the companion star. From high-speed ...
Palmitoyl carnitine : an endogenous promoter of calcium efflux from rat heart mitochondria
(1988)
The effects of the fatty acid ester palmitoyl carnitine (PC) on mitochondrial Ca2+ handling and ATP synthesis are described. At low concentrations (5–40 μM) PC was found to produce changes in mitochondrial Ca2+ handling, ...
Efficacy of ivermectin against Cooperia curticei infection in sheep
(1988)
Lambs were inoculated with a single dose of Cooperia curticei. Subcutaneous administration of ivermectin at a dosage of 200 micrograms/kg of body weight resulted in 61.1% and 90.4% anthelmintic efficacy, when measured at ...
Effects of experience on microcomputer use in primary schools : results of a second survey
(1988)
Following an initial survey of microcomputer use in Hertfordshire primary schools, a second, follow-up survey was conducted two years later to examine how experience had changed attitudes and use. This second survey provided ...
Infrared polarimetry of dark clouds. II : Magnetic field structure in the Rho Ophiuchi dark cloud
(1988)
K-band polarimetry of 20 sources embedded within the densest region of the Rho Oph dark cloud has been obtained. The degree of polarization ranges from 1.1 to 7.4 percent, and the position angles have a bimodal distribution, ...
Gene amplification and expression in plants by a replicating geminivirus vector
(1988-01-01)
The use of plant DNA viruses as vectors for the transfer of foreign genes to plants offers two potential advantages over other, existing methods of producing transgenic plants. First, these viruses sys-temically infect ...
Approximate expressions of maximum value of stress intensity factor of nozzle corner cracks
(1988-01-01)
Based on the flat plate-nozzle model loaded by uniform uniaxial tension, through some suitable reduction and approximation, the maximum value of stress intensity factor (K) along a crack front can be expressed by the weight ...
