The changes in some factors of the innate immunity (phagocytosis, complement, lysozyme); haematological parameters-leukocytes, erythrocytes, differential white blood cell counts, haemoglobin, haematocrit and the serum concentrations of the microelements zinc and iron in six 2- to 3-months-old female piglets after the intravenous administration of(More)
The approach proposed in the paper represents financial-economic systems with one input and one output through the optimal singular adaptive M3A1N computer observer as an arbitrary limited set of discrete linearized observable submodels with unknown parameters, unknown initial vector of the endogenous state variables and unknown current state vector of the(More)

The terms of strict convexity, convexity and non-convexity and a new measure of risk in the quadratic problems of portfolio optimization and their relation to some non-singular and singular analytical solutions to the problem of portfolio selection under risk are introduced, investigated and illustrated. The results are interpreted in view of portfolio(More)
Investigated were a total of 123 birds of the White Leghorn breed and 50 birds of the White Plymouth Rock breed. Preliminary studies were carried out on the LD50 amount of lindane (151 mg/kg body mass) with 6 groups of chickens. The birds were divided into 4 subgroups for each breed. The first subgroup was a control one and was not given lindane, and the(More)
Experimental tibial osteotomy was performed in 24 dogs, fixed by either intramedullary (IMO; n = 12) or plate and screw osteosynthesis (PLO; n = 12). Six dogs with IMO and another six with PLO were subjected to daily therapeutic ultrasound therapy at the site of osteotomy for 10 days, starting from the first post-operative day. The other dogs served as(More)
