“…Актуальність теми. Хвороби сечовидільної системи у кішок -це гетерогенна група захворювань, що характеризується схожими клінічними ознаками, в тому числі гематурією (макроскопічною і мікроскопічною), дизурією, болючим і прискореним сечовипусканням, неможливістю утримувати сечу (Koba, Lifentsova, Novikova, & Gluschenko, 2018;Sapozhnikov, Mar'in, Ljashenko, 2015). Нажаль, коли господар тварини помічає зміни у стані здоров'я, то ураження вже мають значний деструктивний вплив на органи сечовивідної системи, а іноді і незворотні зміни (Sedoshkina, & Filioglo, 2019).…”

The subject of timely diagnosis and prevention of urinary system diseases is an essential argument in life quality and health of pets. The present article exposes conducted test on supplement into basic ration of "Phytovit" and "VESELIY KIT" feed supplements to cat breeds like exotic short-haired and Persian. Herbal extracts (birch buds, cranberry, nettle, plantain and lespedeza) with addition of beer yeasts and vitamin-mineral complex are used as active ingredients in presented feed supplements. Administration effectiveness of feed supplements was analyzed as a result of animal common state (nutritional state, skin and coat state, presence/absence of secretion from nose, eyes, etc.) and blood biochemical rates (urea, creatin). During the entire period of the test (4 weeks (I, II, IV and V groups), 8 weeks-III group) the animals were active, with satisfied appetite, they have normal reaction on sound and light irritants. Disorders in breathing, urination and defecation were not observed. Coat excretion in control groups took a place 1-2 times a week via vomiting, whereas in period of the first week of Phytovit feed supplement administration (for coat excretion) the process of vomiting was observed in 20% of cats; and starting the second week of feed supplement administration the coat in animals was excreted via digestive path with feces. Under the conditions of Phytovit supplement administration (for strong nervous and immune system) more calm behavior was observed in animals during the test starting from the second week of administration. Administration of Phytovit feed supplement (for coat) has led to improvement of skin common state and coat cover (dissolution of dander-after week of administration, appearance of shine and reduction of coat prolapse-after two weeks of administration) in relation to control one. Application of feed supplement "Veseliy Kit" and Phytovit (prevention of kidney stone disease) in cats, opposite to control had an improvement in skin state, changes and disorders of urinary system were not observed in difference to blood biochemical rates dynamics.

“…Особенности синтеза самодвойственных устройств и вычислительных систем рассмотрены не только в многочисленных публикациях отечественных и зарубежных ученых, но и в трех монографиях [15][16][17]. Отметим, что общей особенностью всех самодвойственных устройств является использование для реализации временнóй избыточности и импульсного режима функционирования, что как раз и позволяет контролировать вычисления по принадлежности формируемых функций к классу самодвойственных.…”

Aim. To identify the specificity of error detection as part of self-dual calculations testing by automation devices, as well as to propose a method for organising calculations testing that would allow detecting any malfunctions from the defined model. Methods. The paper used methods of technical diagnostics of discrete systems, Boolean algebra, and combinatorics. Results. The specificity of error detection at the outputs of self-dual digital devices of combination type were analysed. The conditions for detecting and not detecting errors at the outputs of self-dual combinational circuits were formalised. In practice, the latter allow – by analysing potential errors at the outputs – creating fully self-checking circuits. At the same time, it is noted that if full coverage of all errors at the outputs of self-dual circuits cannot be achieved when computing-testing only on the basis of whether a function belongs to the self-dual class, then in some cases that can be made possible through additional checking of whether the generated code vectors belong to a pre-selected redundant code. It is established, what features of actual digital devices enable large numbers of errors compensated for by self-dual testing. It is theoretically determined that, in real practical applications with self-dual computing testing, the larger is the number of input variables, the higher is the probability of not detecting an error due to a larger number of combinations of distortions at the outputs. However, the greater is the number of functions implemented by a device, the higher is the probability of error detection. Nonetheless, in practice, each case of computations testing based on the self-duality of calculated functions should be treated individually for each digital device. The paper presents some experimental results that demonstrate the specificity of error detection at the outputs of self-dual combinational circuits using various circuit design methods based on compressing the signals received from the monitored facilities using modified Hamming codes (Hsiao codes). Conclusion. The conditions for detecting errors at the outputs of self-dual digital devices established in this paper allow practically synthesising self-checking computer systems with improved checkability as compared with conventional approaches to their implementation.
