AIMS To determine if exogenous melatonin (MEL) influences growth of Escherichia coli O157:H7 in pure culture and if MEL affects faecal shedding patterns of E. coli O157:H7 or total leucocyte counts in sheep. METHODS AND RESULTS Two strains of E. coli O157:H7 were cultured in the presence of varying concentrations of MEL. Maximal specific growth rates of E.coli O157:H7 strains were not affecte...

the most current pursuit algorithms for moving targets which are presented so far in the literatureare pure pursuit and pure rendezvous navigations. recently, one of the present authors has introduced ageometric model for the pure pursuit navigation algorithm. here, in this paper, we study a new algorithm forthe pursuit navigation problem which is a combination of both of the above algorithms. ...

in this paper‎, ‎we introduce the notion of $(m,n)$-‎algebr‎aically compact modules as an analogue of algebraically‎ ‎compact modules and then we show that $(m,n)$-algebraically‎ ‎compactness‎ ‎and $(m,n)$-pure injectivity for modules coincide‎. ‎moreover‎, ‎further characterizations of a‎ ‎$(m,n)$-pure injective module over a commutative ring are given‎.

I. In Expt I , four adult wether sheep were given diets of hay or dried grass in an alternating sequence of feeding treatments. Each treatment period lasted for 20 days and blood samples were taken from the sheep on the last day of each period. When the diet of hay (linoleic: linolenic acid ratio 1.40) was replaced by one of dried grass (1inoleic:linoltnic acid ratio 0.28), there was an increas...

Elsden (1945) has shown that the volatile acids in the rumen fluid of sheep are chiefly acetic, propionic, and butyric. Barcroft, MoAnally, and Phillipson (1944) showed that the concentration of volatile acids in the blood draining the rumen was higher than that in the entering blood, indicating absorption from the rumen. Elsden postulated that propionic acid did not arise directly in cellulose...

An outbreak of necrotic dermatitis in sheep was intensively investigated. Initially 19 of 147 Letelle (Merino-type) ewes were identified but closer inspection revealed 57 sheep that had skin lesions, some very slight, and that the majority (46 or 80%) had lesions only above the lips. A small number of them had multiple lesions on the legs or vulvae apart from lip lesions. Seven had only vulvar ...

Prolactin has been obtained from sheep pituitary glands by several methods (1, 2). Cole and Li (3) described a simplified procedure for the preparation of sheep prolactin and its characterization by physicochemical methods (4, 5). The same investigators reported later that prolactin obtained by this method was electrophoretically heterogeneous, but that the three components had essentially equa...

A female Shetland sheep dog died suddenly with hemorrhagic diarrhea and vomitting, and was examined pathologically and microbiologically. Gross pathological change was restricted to the intestinal tract. The intestine contained watery, blood-stained fluid. Histopathologically, the principal intestinal lesion was superficial mucosal hemorrhagic necrosis at the jejunoileum. Many Gram-positive bac...
