Angora goats are known to be vulnerable to cold stress, especially after shearing, but their thermoregulatory responses to shearing have not been measured. We recorded activity, and abdominal and subcutaneous temperatures, for 10 days pre-shearing and post-shearing, in 10 Angora goats inhabiting the succulent thicket of the Eastern Cape, South Africa, in both March (late summer) and September (...

Direct transmission of Q fever between persons who have been exposed to Coxiella burnetii and their family members has been hypothesized on the basis of the results of serological surveillance. We studied nine shepherds who were employed in Spain during the sheep shearing season. After they returned to Poland, Q fever was detected in these shepherds and their wives. The titers of serum antibodi...

An experiment was designed to evaluate the effects of five sire breeds (Dorset, Finnsheep, Romanov, Texel, and Montadale), two dam breeds (Composite III [CIII] and northwestern whiteface [WF]), and three shearing seasons (December, February, and April, corresponding to August, October, and December breeding seasons) and their interactions on wool and other characteristics of F1 ewes. Fleeces we...

Compression neuropathy of the median nerve in the carpal tunnel, better known as the carpal tunnel syndrome, occurs most commonly in adults aged between 30 and 60 years ofage, and is five times more common in women than men.' Any condition that crowds or reduces the capacity ofthe carpal tunnel may initiate the symptoms. Local causes include malaligned Colles' fracture, oedema from trauma or in...

This paper argues that the term “robotics” needs to be redefined as “the science of extending human motor capabilities with machines,” and uses the author’s experience with robotics over the past 25 years to support this argument. The current definition is tied by default to the term “robot,” which emerged from science fiction—this tie needs to be broken if robotics research is to be based on r...

We consider the adiabatic shearing of an incompressible non-Newtonian liquid with temperature dependent viscosity, subjected to steady shearing of the boundary. Identical equations govern the plastic shearing of a solid exhibiting thermal softening and strain rate sensitivity with constitutive relation obeying a certain power law. We establish that every classical solution approaches a uniform ...
