    In investigation of boundary-value problems for certain partial differential equations arising in applied mathematics, we often need to study the solution of a system of partial differential equations satisfied by hypergeometric functions and find explicit linearly independent solutions for the system. In this investigation, we construct special solutions for a certain class of degenerating differential equations of parabolic type of a high order. These special solutions are expressed in terms of hypergeometric functions of one variable

    The using of antibiotics and antimicrobials drugs without control may leads to the development of numerous complications and resistance of microorganisms to antibiotics. The using of antibiotics and antimicrobials drugs should are controlled on farms. That is why the monitoring and determination of sensitivity of bacterial diseases agents to antimicrobial drugs are very important. Results of pasterella, of salmonellas’ and kolibakterias’ monitoring in farms of Azerbaijan are introduced in the article. The studies were conducted on the basis of the department for quality control of biological preparations of the Azerbaijan Scientific Research Institute. Sampling for microbiological studies was carried out on farms from pathological material and premises where livestock of different age groups are kept. At the same time, the spread of the disease, incidence, mortality, mortality, age-related features, economic losses caused by bacterial pathogens were taken into account. Inoculations from samples of bone, brain, heart, liver, spleen, and lymph nodes were performed on simple and selective and differential diagnostic nutrient media. The results were read visually. Antibiotic sensitivity was determined by agar disco-diffusion method. Microbiological monitoring of a number of farms in Azerbaijan has shown that agents of bacterial diseases’ are widely spread. Between the isolated pasterella agent largest number were accounted for Salmonella (54.1%) and the Escherichia (30.8 per cent). The rest (15.1%) were isolated cultures of Proteus, Pseudomonas, Klebsiella, Salmonella, Campylobacteria, Enterobacteria, and Clostridia Citrobacter. This indicates that systematic control over the availability of the causative agents of bacterial infections in all critical points of farms is very necessary. Among isolates that were isolated from ill calves and objects, differences in their sensitivity to antimicrobial agents from active substances that officially have registered in our country were discovered. Bactericidal activity of relatively isolated cultures was showed by oxitetraciklin, colistin, ftorfenicol, zeftiocur, doxicyclin, enroxil and sarafloxacin.Π’ ΡΡ‚Π°Ρ‚ΡŒΠ΅ ΠΏΡ€ΠΈΠ²Π΅Π΄Π΅Π½Ρ‹ Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ ΠΌΠΎΠ½ΠΈΡ‚ΠΎΡ€ΠΈΠ½Π³Π° Π²ΠΎΠ·Π±ΡƒΠ΄ΠΈΡ‚Π΅Π»Π΅ΠΉ Π±Π°ΠΊΡ‚Π΅Ρ€ΠΈΠ°Π»ΡŒΠ½Ρ‹Ρ… ΠΈΠ½Ρ„Π΅ΠΊΡ†ΠΈΠΉ, Π²Ρ‹Π΄Π΅Π»Π΅Π½Π½Ρ‹Ρ… Ρƒ тСлят, ΠΏΠ°Π²ΡˆΠΈΡ… ΠΎΡ‚ пастСрСллСза Π² хозяйствах АзСрбайдТана.

    On a boundary-value problem in a bounded domain for a time-fractional diffusion equation with the Prabhakar fractional derivative

    Get PDF
    We aim to study a unique solvability of a boundary-value problem for a time-fractional diffusion equation involving the Prabhakar fractional derivative in a Caputo sense in a bounded domain. We use the method of separation of variables and in time-variable, we obtain the Cauchy problem for a fractional differential equation with the Prabhakar derivative. Solution of this Cauchy problem we represent via Mittag-Leffler type function of two variables. Using the new integral representation of this two-variable Mittag-Leffler type function, we obtained the required estimate, which allows us to prove uniform convergence of the infinite series form of the solution for the considered problem

    Decomposition formulas for some quadruple hypergeometric series

    Get PDF
    In the present work, the authors obtained operator identities and decomposition formulas for second order Gauss hypergeometric series of four variables into products containing simpler hypergeometric functions. A Choi–Hasanov method based on the inverse pairs of symbolic operators is used. The obtained expansion formulas for the hypergeometric functions of four variables will allow us to study the properties of these functions. These decompositions are used to study the solvability of boundary value problems for degenerate multidimensional partial differential equations
