Responsiveness of adult pet dogs (Canis familiaris) to an unfamiliar human was observed in two studies. Subjects were faced with an approaching woman (Stranger) who showed definite signs of friendliness and threat during alternate approaches. Observations consisted of two episodes: the Stranger either approached the dog in normal speed of walk while talking to it and finally petted it gently (F...

DoSen, K., Rudimentary Kripe models for the intuitionistic propositional calculus, Annals of Pure and Applied Logic 62 (1993) 21-49. It is shown that the intuitionistic propositional calculus is sound and complete with respect to Kripke-style models that are not quasi-ordered. These models, called rudimentary Kripke models, differ from the ordinary intuitionistic Kripke models by making fewer a...

platelet studies were done in healthy male voluntecrs and in thrombocytopcnic patients. Some of the platelets used in the study were isolated by mcclanical apheresis using .itn"t the Haemonetics blood processor 30, the IBM btood prooGsor 2997 or the Fenwal C$3000 blood prooessor before freezing" Other platelets wene isolatod from individud units of whole blood-and pooted before freezing. The pl...

Objective. – The aim of this study was to compare the immediate effects of standard physiotherapy (S) and balneotherapy (B) on the postural capacity of subjects with lower-limb injuries. Methods. – The postural sway of 12 voluntary subjects was evaluated before (REF1 and REF2) and after two different physiotherapy sessions performed in the swimming pool (B) or under (S). The centre of pressure ...

Photosynthetically-active radiation is a necessary input in applications dealing with plant physiology, biomass production and natural illumination in greenhouses. Unfortunately, a worldwide routine network for the measurement of photosynthetically-active radiation is not yet established and it is often calculated as a constant ratio of the broadband solar radiation. This ratio is affected by m...

The use of Judas goats (JGs; Capra hircus) to locate remnant animals is a powerful tool for enhancing feral goat eradication efforts, being especially important to island conservation programs. JGs are goats that are captured, fitted with radio telemetry collars and released. As goats are gregarious, JGs search out and associate with other goats. They can then be tracked down and any associated...

Ruminants prefer hay cut in the afternoon to hay cut in themorning, presumably because hay cut in the afternoon contains higher concentrations of non-structural carbohydrates than hay cut in the morning. We determined if adding sugars (glucose and sucrose) to ground hay would account for differences in preference and affect intake of hay. Alfalfa hay cut either in the afternoon (PM) or the foll...

Eggs from (C57B1 x A a G ^ mice were activated by treatment with hyaluronidase, which removed the follicle cells, and cultured in vitro. Observations were made 6-8 h after hyaluronidase treatment to determine the frequency of activation and the types of parthenogenones induced. Cumulus-free eggs resulting from hyaluronidase treatment were incubated for 2\ h in culture media of various osmolarit...

Objectives. – The aim of the present study was to compare and contrast developmental dyspraxia and dyspraxia following preterm birth. Material. – Three different domains (attention–executive function, sensorimotor and visuospatial functions) were evaluated using Nepsy battery tests and the Purdue pegboard test. Method. – The results of a neuropsychological evaluation of 32 children with develop...
