A reciprocating friction machine Tribal-T intended for automated quality control of the rubbing surfaces of tribopairs is described. The distinctive feature of the machine consists in implementation of the forced relative motion due to the frictional interaction of the rubbing surfaces fixed on the drive and conjugate platforms. Continuous processing of the signals from displacement sensors is carried out under conditions of continuous recording of mutual displacements of loaded tribopairs using classical approaches of the theory of automatic control to identify the tribological characteristics. The machine provides consistent visual real time monitoring of the parameters. The MATLAB based computer technologies are actively used in data processing. The calculated tribological characteristics of materials, i.e., the dynamic friction coefficient, damping coefficient and measure of the surface roughness, are presented. The tests revealed that a Tribal-T reciprocating friction machine is effective for real-time study of the aforementioned tribological characteristics of materials and can be used for monitoring of the condition of tribo-nodes of machines and mechanisms.

Information is provided on the causative agents of fasciolosis and the developmental biology of Fasciola hepatica. Fasciolosis of cattle is widespread in the conditions of the Kaluga Region and the Central Federal District on farms of different forms of ownership. The greatest number of F. hepatica eggs in 1 g of feces in cattle is established in JSC "Iskra" - 175,4 specimens, the lowest - in the samples from cows from private farms - 87,6 sp. At the opening slaughter of cattle at meat processing plants region and slaughterhouses invasion of their fasciolae was 34.8%. The average number fascial one infected animal was 32.1 specimens, including adult - and larval specimens of 25.2 and 6.9 copies At veterinary-sanitary expertise and helminthological autopsy of the liver, gallbladder and bile ducts installed year-round invasion fasciolae mainly in the adult stage. Young animals of the current year are infected with fasciola in the pasture massly in August-September, and the extent of invasion in November was 4.3%, for winter-stabling months an average of 12.6%, in March - 17.9% and in April after de-worming - 5.9%.The data obtained in the study of the distribution of the small pond has shown that in the Kaluga region these mollusks are widespread. In this case, the invasion of the small pond snail by larval forms of fasciolae in different years has its own peculiarities, which are influenced by climatic factors.The different dosage forms of clozantel - Rolenol and Santel and Genamectin with mixed fascioliasis and hypodermatosis of bovine in the recommended dose against subcutaneous gadfly larvae - provided 100% efficacy. The tested dosage forms of clozantel are similar in effectiveness against subcutaneous gadfly larvae (EE-100%) and fasciol (EE-95 and 90%, IE-97.4 and 96.3%).The therapeutic and economic effectiveness of complex domestic preparations of Helmicide and Fascocida in spontaneous fascioliasis of cattle is studied.
