In this paper we investigate the Church-Rosser property (CR) for Pure Type Systems with-reduction. For Pure Type Systems with only-reduction, CR on well typed terms follows immediately from CR on the so called 'pseudoterms' and subject reduction. For-reduction, CR on the set of pseudoterms is just false, as was shown by Nederpelt 1973]. Here we prove that CR (for) on the well-typed terms of a x...

Small coded hole patterns can be branded, for identification purposes, on to sheep pelts. This paper describes our approach to the problem of automatically finding the pattern in a given back-lit wholepelt image and then recognising the orientation and other major components of that pattern despite noise and pattern warping. The pattern-finding stage principally uses binary morphology combined ...

Abstract This article explores the relationship between tax law and settler colonialism by looking at ways in which taxes can be part of “civilizing” process Indigenous peoples. In 1921, Territory Alaska enacted a “license on business fur-farming, trapping trading pelts skins fur-bearing animals.” Since most trappers were Natives, “fur tax” de facto targeted them. unpacks sociocultural politica...

Objective(s): Human and animal studies have shown a close relationship between obesity and asthma severity. Here, we examined the effects of diet-induced obesity (DIO) on the expression levels of IL-1β, IRAK-1 and TRAF-6 mRNA in male Wistar rats tracheal after sensitization with ovalbumin (OVA). Materials and Methods:Twenty male Wistar rats divided to four groups, included, control group with ...

Dining opportunities are rare for ticks. The notorious pests spend as much as 90% of their lives clambering around in leaf litter and only embark on epic expeditions to the tips of grass and leaves when they need to feed. Wrapping their limbs around slender smooth stalks of grass when they ascend, ticks must also grasp any passing opportunity to latch onto smooth skin or the hairy pelts of anim...

Carnivora includes three independent evolutionary transitions to the marine environment: pinnipeds (seals, sea lions, and walruses), sea otters, and polar bears. All three lineages must contend with the thermal challenges of submersion in the marine environment. In the present study, we investigated changes in the fur associated with the transition from a terrestrial to an aquatic lifestyle, co...

THE ONLY FUR ANIMALS that are now being raised commercially to any great extent are silver foxes and minks. Martens and fishers also have commercial possibilities if satisfactory reproduction can be obtained in captivity. Attempts have been made at one time or -another, largely through the efforts of propagandists, to ''ranch-raise'' skunks, badgers, raccoons, beavers, and muskrats for their fu...

Symptomatic and immunologic responses to allergens from laboratory mice were studied in a research institute. Subjects who had been exposed to mice and 50 unexposed subjects were studied by questionnaire and by prick tests with seven prevalent aeroallergens and allergens from mouse urine and pelts. Of the 121 exposed subjects, 39 (32.2%) had respiratory, ocular, or cutaneous symptoms after expo...
