The results of biochemical and clinical investigations of a number of azoospermia cases are presented. It was found that serious testicular complaint is usually accompanied by a reduction in the volume and a disturbance in the concentration of the constituents of the accessory gland secretion.Statistical analysis of the fructose concentration indicated that the minimum fructose average was that of the Klinefelter.

In Part I the musculature of the internal organs of the male blow-fly, C. erythrocephala, testis, vas efferens, accessory gland, vas deferens, and ejaculatory sac and duct, is described, together with the movements observed in them and the passage of secretions down the system. It is suggested that the testicular and accessory gland secretions are ejaculated separately. The musculature, mechanics and co-ordinated movements of the external organs and associated structures are also described.In Part II the generative organs of the female, except the ovaries, with special reference to their musculature and movements, and the musculature of the ovipositor are described and compared with those of M. domestica. It is suggested that the male accessory gland secretion is kept separate from the testicular secretion, the former passing into the lateral sacs of the female and the latter into the spermathecae.In Part III the relation of the parts of the two sexes during coitus is discussed.

The general population increasingly uses digital services, meaning services which are delivered over the internet or an electronic network, and events such as pandemics have accelerated the need of using new digital services. Governments have also increased their number of digital services, however, these digital services still lack of sufficient information security, particularly integrity. Blockchain uses cryptographic techniques that allow decentralization and increase the integrity of the information it handles, but it still has disadvantages in terms of efficiency, making it incapable of implementing some digital services where a high rate of transactions are required. In order to increase its efficient, a multi-layer proposal based on blockchain is presented. It has four layers, where each layer specializes in a different type of information and uses properties of public blockchain and private blockchain. An statistical analysis is performed and the proposal is modeled showing that it maintains and even increases the integrity of the information while preserving the efficiency of transactions. Besides, the proposal can be flexible and adapt to different types of digital services. It also considers that voluntary nodes participate in the decentralization of information making it more secure, verifiable, transparent and reliable.

AbstractGiven the visibility and obvious importance of judicial power in the age of the Charter, it is important to develop the conceptual vocabulary for desribing and assessing this power. One such concept that has been applied to the study of appeal courts in the United States and Great Britain is “party capability”, a theory which suggests that different types of litigant will enjoy different levels of success as both appellant and respondent. Using a data base derived from the reported decisions of the provincial courts of appeal for the second and seventh year of each decade since the 1920s, this article applies party capability theory to the performance of the highest courts of the ten provinces; comparisons are attempted across regions and across time periods, as well as with the findings of similar studies of American and British courts.

Lectins are glycoproteins of a non-immune origin often used as histochemical reagents to study the distribution of glycoconjugates in different types of tissues. In this study, we performed a comparative cellular localization of sugar residues in bull and donkey testes using immunofluorescent lectin histochemistry. We inspected the cellular localization of the glycoconjugates within the testes using 11 biotin-labeled lectins (LCA, ConA, PNA, WGA, DBA, SBA, ECA, BPL, PTL-II, UEA-1, and PHA-E4) classified under six groups. Although the basic testicular structure in both species was similar, the cellular components showed different lectin localization patterns. The statistical analysis revealed no significant association between the intensity of labeling and different variables, including group and type of lectin and type of cell examined, at p < 0.05. However, a stronger response tended to occur in the donkey than in the bull testes (odds ratio: 1.3). These findings may be associated with the different cellular compositions of the glycoproteins and modification changes during spermatogenesis. Moreover, glycoconjugate profiling through lectin histochemistry can characterize some cell-type selective markers that will be helpful in studying bull and donkey spermatogenesis.

The results of the study of the ballast layer consolidation after the work of ballast-tamping machines of different types are given in the article. The existing methods of determining the degree of consolidation of the ballast layer are analysed. The seismic method was improved by means of a complex dynamic and kinematic interpretation of the impulse response. For the dynamic interpretation with the use of statistical analysis, the features are selected so that they correspond to the degree of consolidation of the ballast layer. On the basis of researches, a device and software were developed that allow an automated evaluation of the ballast layer consolidation based on the kinematic and dynamic analysis of the measured impulse response. The measurements of the degree of the ballast layer consolidation after an operation of ballast-consolidation machines in different sequences allowed establishing the efficiency of the consolidation and the feasibility of the machines’ application.

In veterinary medicine, one of the most relevant area is dentistry of small pets. Of all dentistry diseases - 80% of cases are due to Feline odontoclastic resorptive lesion (FORL), which is more often diagnosed in cats. 35 cats have been diagnosed with den-tal disorders in vet-clinic "Altervet" for the period from November 2018 to April 2019. The analysis of the statistical information was carried out: 86 % of cats, that is 30 heads, were diagnosed FORL. The assess-ment was carried out according to the degree of tooth damage from x-rays images, and there are 2 types of resorption today: type 1 and type 2. Moreover, one of the examined cats simultaneously detected both types of FORL. Various degrees of tooth damage have been studied. Lesions of various parts of the tooth (crowns, necks, aboral and ros-tral roots of the teeth) were found, which were marked on radiographs. A statistical analysis of the incidence by breed, age, sex of animals and types of feed was conducted. The middle animal age of the disease inci-dence is 10 years. It was found that animals with pathology were nourished different types of food: mixed, dry, wet and natural. However, a greater number of cats with FORL were fed mixed (14 heads) and dry (8 heads) feed, 47 and 27%, respectively. It was found that in male this pathology is di-agnosed more often, in our case it is 73%, than in female- 27%.The disease was more common in mongrel cats – 18 heads, than in thoroughbred animals -12 heads, it turned out 60 and 40% of the number of affected animals. Reliable data on the influence of sex and breed on the occurrence of FORL has not been established.

Data of foreign literature concerning sutureless formation of the colorectal anastomosiswith the help of cyonocrylate adhesives are presented in the article. These are quick acting glues, available on the Ukrainian market, and may be used by Ukrainiansurgeons in implementation of their ideas as to the sutureless connection of organs in theexperimental and clinical investigations.12 different types of cyanocrylate adhesives as to their resistance to the rupture of theconnected by them large intestine segments, were studied. Questions of the technicalformation of the sutureless anastomoses were considered. When substantially newtechnical devices for gluing together the organs are absent, progress is hardly possible.Objective – to acquaint the domestic surgeons and oncologists with modern achievementsof foreign scientists in the field of sutureless colorectal anastomosis formation by meansof cyanocrylate adhesives.Conclusions. For some time past foreign surgeons the problems of colorectal anastomosesintensively develop the problems of colorectal. This is due to the fact that indices ofcolorectal anastomosis insufficiency remain on high levels. Unfortunately, the hopesthat the introduction of modern advanced stapler anastomotic techniques can radicallyreduce the frequency of this complication were not justified.
