The relaxation of the reciprocity condition for pairwise comparisons is revisited from the optimization point of view. We show that some special but not extreme cases of the Least Squares Method are easy to solve as convex optimization problems after suitable nonlinear change of variables. We also give some other, less restrictive conditions under which the convexity of a modified problem can be assured,...
Trichotillomania (TTM) is most frequently characterized by small bald spots on the posterior part of the body of dogs and cats. The disease arises on a psychogenic basis and is a consequence of distress: the animal deprives itself of hair and brings about skin lesions by intensively licking its body. It has been relatively rarely described in cats and, in the case discussed here, is unique in view...
The aim of our study was to investigate the amount of 110 pesticide residues in cereals and foodstuff from Poland as a part of official control. A total of 89 samples were collected in 2009-10. In 84.2% of the samples no residues were found: 15.8% of samples contained pesticide residues below the maximum residue limit. Pirimiphos-methyl was the most frequently found pesticide. The results show that...
Celem pracy było określenie udziału kwasów tłuszczowych w mleku krów rasy polskiej holsztyńskofryzyjskiej, uwzględniając wpływ kolejności laktacji i fazy laktacji. Do badań wybrano 48 krów rasy polskiej holsztyńsko-fryzyjskiej, będących w różnym wieku: I, II, III i IV laktacja (po 12 szt. w każdej z nich). Od każdej krowy pobierano próby mleka z uwzględnieniem fazy laktacji, tj. w następujących dniach...
The objective of this study was to examine the independent effect of helminths infection on biochemical blood parameters in Beagles intended for laboratory use which may contribute to a change of experimental results. As a result of research, the authors confirmed the negative effect of helminth invasion on the metabolism of the liver and kidney in laboratory dogs. Stool samples from thirty Beagle...
Since 1995 Poland has been considered as free from classical swine fever (CSF) by The World Organization of Animal Health - OIE. However, bearing in mind the epizootic situation in Europe and reported cases of this disease in 2011 in Lithuania in particular, infection of the CSF virus remains a real threat to swine breeding in Poland. Poland is constantly monitoring the occurrence of CSF among swine...
The liver and kidneys of broilers fed during the first two weeks of fattening a fodder containing the addition of 0.025% propolis and/or 0.5% pollen were examined macroscopically and microscopically. Additionally, the effects of these substances on the results of breeding and on pathomorphology of the liver and kidneys in the course of natural, asymptomatic infection with Salmonella Enteritidis were...
