Fault diagnosis mechanism of gears and bearings for coal mining equipment in a complex geological environment
Authors: Wang Shuilin , Liu SongYong , Meng Fanping
Published: June 2021

The traditional research method of fault diagnosis mechanism has poor stability, which leads to the difference of fault diagnosis and location results. Therefore, under the complex geological environment, a new research method of fault diagnosis mechanism of gear and bearing for coal mining equipment is proposed. This method calculates gears and bearings’ yield strength by analyzing coal mining equipment’s bearing capacity elasticity. According to the fitting degree, the equipment sample’s projection space is confirmed, the fault features of gear and bearing are extracted by segmentation algorithm, the optimal fitness is set by positioning algorithm, the location of fault center is obtained, and the fault mechanism diagnosis is studied. Experimental results show that compared with the traditional method, the proposed method is more stable, and the difference in fault diagnosis results is minimal. It can be seen that this method is more suitable for fault diagnosis of coal mining equipment.

Authors:   I. Horbachevsky Ternopil National Medical University, Ukraine, Mochulska O.M.
Published: June 2021

Skin diseases have become one of the most relevant problem due to their global prevalence and intensive growth nowadays. Significantly increased the interest in studying of the life quality of patients with acute and chronic dermatological diseases. The life quality of the patient is the most objective characteristic of the impact of the disease on the patient's condition and various areas of his activity. Emotional or social disorders caused by the disease often do not allow the patient to feel full and healthy person even if clinical recovery. The peculiarities of patients' perception of somatic disease significantly affect both on its course and on the effectiveness of therapeutic measures. Skin diseases form an aspect of life quality that can be dangerous for the prognosis. Dermatological diseases can lead to significant limitations in the physical, emotional and social aspects of patients' lives and can interfere with success in learning and at work, as well as in personal life. In dermatology to assess the quality of life of patients are used: general medical scales, special dermatological scales, dermatological scales for certain nosologies. Purpose — to analyze literary datas on the research methods of life quality in children with dermatological diseases. Conclusions. Determining and evaluating indicators of life quality in patients is a valuable and reliable indicator of the general condition, that allows to monitor the effectiveness of treatment depending on the patient's condition and creates an objective picture of the disease. Assessment of quality of life in patients with dermatological diseases makes it possible to understand the essence of the clinical problem, to determine the most rational method of treatment, as well as to assess its expected results by parameters that are at the intersection between the scientific approach and the patient's point of view. No conflict of interest was declared by the author. Key words: assessment of life quality, dermatological diseases, children.
CONSTRUCTION OF COMPLEX SCHEDULES FOR EXECUTION OF TASK PACKAGES AT FORMING SETS IN SPECIFIED DIRECTIVE TERMS
Authors: Krotov Kirill , Skatkov Aleksandr
Published: June 2021

The current state with the solution of the problem complex planning of the execution of task packets in multistage system is characterized by the absence of universal methods of forming decisions on the composition of packets, the presence of restrictions on the dimension of the problem and the impossibility of guaranteed obtaining effective solutions for various values of its input parameters, as well the impossibility of registration the condition of the formation of sets from the results. The solution of the task of planning the execution of task packets in multistage systems with the formation of sets of results within the specified deadlines has been realized of authors in article. To solve the planning problem, the generalized function of the system was decomposed into a set of hierarchically interrelated subfunctions. The use of decomposition made it possible to use a hierarchical approach for planning the execution of task packets in multistage systems, which involves defining solutions based on the composition of packets at the top level of the hierarchy and scheduling the execution of packages at the bottom level of the hierarchy. The theory of hierarchical games is used to optimize solutions for the compositions of task packets and schedules for their execution is built, which is a system of criteria at the decision-making levels. Evaluation of the effectiveness of decisions by the composition of packets at the top level of the hierarchy is ensured by the distribution of the results of task execution by packets in accordance with the formed schedule. To evaluate the effectiveness of decisions on the composition of packets, method for ordering the identifiers of the types of sets with registration of the deadlines and a method for distributing the results of the tasks performed by packets has been formulated, which calculates the moments of completion of the formation of sets and delays with their formation relative to the specified deadlines. The studies of planning the process of the executing task packages in multistage systems have been carried out, provided that the sets are formed within specified deadlines. On their basis, conclusions, regarding the dependence of the planning efficiency from the input parameters of the problem, were formulated.

Published: June 2021

We perform numerical MHD simulations of the isothermal collapse of magnetic rotating protostellar clouds to investigate initial conditions for protostellar disks formation. The simulations show that a hierarchical structure of the cloud is formed during the isothermal collapse: a flattened cloud envelope with a primary magnetostatic disk inside. The first core forms inside the primary disk further. We investigate the dependence of the characteristics (size, mass, angular momentum) of the envelope and primary disk on the initial thermal, magnetic, and rotational energies. Based on the results of numerical simulation the average brightness temperature in the NH3 line (2,2) is under construction.

Authors:   Ural Federal University, Punanova A. F. , Petrashkevich I. V. ,   Ural Federal University
Published: June 2021

In this work, we study how deuterium fraction changes depending on the physical conditions in cold cores embedded in the molecular clouds of Taurus, Perseus and Ophiuchus. The results show that the deuterium fraction in cold cores varies in different star-forming regions. In the densest and most turbulent of the studied regions, L1688 in Ophiuchus, the deuterium fraction is two times higher than that of L1495 in Taurus and B5 in Perseus. In L1495 and L1688, the deuterium fraction in the central parts of the cores and in their envelopes differ by a factor of 10, while in B5 only by a factor of 2—3.

Authors: PINTO Thiago David Alves , ALVES Thaís David das Neves , PINTO Sebastião Alves , OLIVEIRA Enio Chaves
Published: June 2021

ABSTRACT Background: Inhibitors of the epidermal growth factor (EGFR) represent an effective therapeutic option for patients with metastatic colorectal carcinoma, free of activating mutations in KRAS and NRAS. However, the research of mutations is of high cost and scarcely accessible. The expression of the EGFR by immunohistochemistry predicting the mutation status of the expanded RAS (KRAS and NRAS), may allow treatment by a diagnostic method less costly and more accessible. Aim: Investigate the correlation between the clinical-pathological data, the cytoplasmic-membrane expression of the EGFR and the mutational status of the expanded RAS. Method: A total of 139 patients with colorectal carcinoma from the archives of Instituto Goiano de Oncologia e Hematologia were evaluated. Results: Mutation of the expanded RAS was detected in 78 (56.1%) cases. The EGFR expression was stratified in 23 (16.5%) “positive”, 49 (35.2%) "negative" and 67 (48.2%) "uncertain". No significant correlation was found between the mutational status of the RAS and the EGFR expression in comparison to age, gender, location, histological type, histological grade and stage. From 23 "positive” cases, 21 (91.3%) showed wild-type RAS gene, and 49 "negative”, 41 (83.7%) presented mutation, resulting in a strong association between EGFR "positive", "negative” groups and the mutational status of the RAS (p<0.001), with 86.1% of accuracy. Conclusions: The cytoplasmic-membrane analysis of the EGFR expression stratified into "positive", "negative" and "uncertain" predicts mutational status of the RAS in 51.7% of the cases (p<0.001), with 86.1% of accuracy.

ABSTRACT Background: Due to the lack of normal standards of anorectal manometry in Brazil, data used are subject to normality patterns described at different nationalities. Aim: To determine the values and range of the parameters evaluated at anorectal manometry in people, at productive age, without pelvic floor disorders comparing the parameters obtained between male and female. Methods: Prospective analysis of clinical data, such as gender, age, race, body mass index (BMI) and anorectal manometry, of volunteers from a Brazilian university reference in pelvic floor disorders. Results: Forty patients were included, with a mean age of 45.5 years in males and 37.2 females (p=0.43). According to male and female, respectively in mmHg, resting pressures were similar (78.28 vs. 63.51, p=0.40); squeeze pressures (153.89 vs. 79.78, p=0.007) and total squeeze pressures (231.27 vs. 145.63, p=0.002). Men presented significantly higher values of anorectal squeeze pressures, as well as the average length of the functional anal canal (2.85 cm in male vs. 2.45 cm in female, p=0.003). Conclusions: Normal sphincter pressure levels in Brazilians differ from those used until now as normal literature standards. Male gender has higher external anal sphincter tonus as compared to female, in addition a greater extension of the functional anal canal

Published: June 2021

Resumo Os Tribunais de Contas brasileiros ganharam bastante notoriedade nos últimos anos. Embora a aplicação do Direito por qualquer órgão esteja aberta às diversas possibilidades interpretativas da lei, a análise das súmulas desses tribunais evidencia grande assimetria na interpretação normativa por parte de tais órgãos, o que pode gerar um tratamento diferenciado em casos semelhantes. Nesse contexto, este artigo buscou identificar assimetrias no conteúdo das súmulas dos Tribunais de Contas brasileiros para verificar se há isonomia na fiscalização dos gestores e organizações do setor público no território nacional. A pesquisa foi realizada a partir de uma metodologia qualitativa, com a utilização do método de análise de conteúdo e o apoio do software Iramuteq. Como resultado, apresenta-se um mapeamento das súmulas dos Tribunais de Contas brasileiros a partir de sete classes (remuneração, aposentadoria, pensão, irregularidades, processo de contas, orçamento e licitação). Tais dados podem ser úteis ao planejamento estratégico na Administração Pública, buscando garantir mais segurança jurídica aos gestores públicos. As conclusões indicaram não existir isonomia na auditoria dos gestores e organizações do setor público no território nacional, especialmente em razão da inexistência de uma Corte Superior de Contas com o papel de harmonizar essa jurisprudência na federação.

Authors: Oddsdóttir Charlotta , Pálsdóttir Guðný Rut
Published: June 2021

Faecal samples were collected from a total of 11 calves on three dairy farms (four from two farms and three from one) where calves generally thrive well and no anti-coccidial treatment is habitually carried out. One of the farms keeps calves in groups on hay/straw bedding, one keeps calves in pairs on plastic slats and then in groups on concrete slats, and the third one keeps calves in groups on concrete slats. Faecal consistency and the total number of Eimeria spp. oocysts per gram faeces (OPG) were determined and species identification was carried out by morphology. Eimeria oocysts were detected in all calves at some point of the study period, and diarrhoea was seen in 55% of the calves. The highest peak in oocyst excretion was 69,300 OPG. The first peak in oocyst excretion was seen 2-3 weeks after calves had been moved to group pens, and a second peak was seen 2-3 weeks later. Nine Eimeria species were found, including E. bovis and E. zuernii. The results are in accordance with previous studies showing that one of the risk factors for Eimeria infection in calves is entering a group pen where older calves are already being kept.

The morphology and sowing qualities of 7 types of hydrangea from the collection of the South Ural Bo-tanical Garden-Institute of the UFIC RAS were studied. The studies were carried out according to stand-ard methods. Is determined the mass of 1000 pieces seeds of each species, seed quality (germination en-ergy and germination in laboratory and soil conditions), the nature of seed germination, as well as their sowing qualities after different storage periods. It was found that the representatives of the Heteromallae subsection are characterized by heavier and larger seeds (the maximum weight of 1000 pieces of seeds is 0.06-0.09 g) compared with the representatives of the Americanae subsection (weight of 1000 pieces is 0.02 g). In addition, representatives of the Heteromallae subsection, with the exception of H. paniculata, showed consistently high rates of germination (72.3-85.8%) and germination energy (63.3-78.1%) under laboratory conditions; with soil sowing, these indicators are also significantly higher than that of repre-sentatives of the Americanae subsection.

The diversity of microbial communities the artificial salt constructions (ASC) located in the medicalpreventive and sanatorium institutions of the Perm region was studied. It was found that the surfaces of the abiotic salt of all ASC were contaminated with microorganisms, and a significant difference was found between the constructions of sylvinite (86.5% of positive samples) and halite (47.4%). The number of viable bacteria, as well as staphylococci, were also higher in sylvinite constructions than in halite ones. Based on bacteriological research and analysis of the 16S rRNA gene nucleotide sequences, the isolated staphylococcus strains belong to the following species: Staphylococcus epidermidis – 42.3% (n=11), S. aureus and S. saprophyticus – 19.2% (n=5), S. simulans – 7.7% (n=2) and one strain of S. cohnii urealyticum, S. hominis, S. warneri – 3.8%. The species composition of microbiocenoses formed on surfaces determined by gas chromatography–mass spectrometry included representatives of 18 genera belonging to the three main phylums: Actinobacteria, Firmicutes and Proteobacteria. Actinobacteria (Actinomyces, Corynebacterium, Nocardia, Propionibacterium, Rhodococcus, etc.) were dominant in both groups ASC. Among Firmicutes, representatives of the genus Clostridium predominated in sylvinite ASC – 63.8% of the total number of bacteria, while in halite they were half as many – 32.1%. The content of coccal microbiota, in contrast, in halite constructions was almost 3 times higher than in sylvinite. Identified quantitative and qualitative indicators of the microbiota of the ASC complement the understanding of the constructions of microbial communities under conditions of high salt load and anthropogenic impact.

Published: June 2021

Materials for environmental impact assessment must contain a description of vegetation and animal population, and an assessment of possible changes in the components caused by human impact. Methodological support for such works is poorly developed in Russia, so there are difficulties in preparing these sections of pre-project documentation for environmentally sustainable design. The purpose of the research is to develop requirements for describing and evaluating vegetation and animal population when performing an environmental impact assessment (EIA). The article offers the authors' approach and provides a list of criteria for the successful development of sections for assessing the state of vegetation and animal population in sustainable design. The proposed approach is based on the authors' personal experience and generalization of existing methods, techniques and regulatory support.

Authors:   Lomonosov Moscow State University, Khusainova Alina S. , Elmanova Darya S. ,   Lomonosov Moscow State University
Published: June 2021

This study is dedicated to identifying residential areas of the Metropolis of Lyon, which combines territorial and ethnic exclusion. In the framework of this study, territorial exclusion is understood as the territorial isolation of residential areas from the main residential area of the agglomeration due to the presence of various kinds of territorial barriers: water bodies, industrial and commercial areas, parklands, large highways. Ethnic exclusion in this study is understood as a partial exclusion from society (social exclusion) of population groups that are ethnically different from the main part of the population. The share of immigrants in the population of the communes and the share of social housing in the total housing stock of the communes of the Metropolis of Lyon were used as markers of ethnic exclusion. A comparison of territorially isolated residential quarters and data on the share of immigrants and the share of social housing revealed social housing quarters that combine signs of ethnic and territorial exclusion of the population: Mas-du-Taureau in the commune Vaulx-en-Velin in the north-east of the Metropolis of Lyon, Parilly and Terraillon in Bron in the east, Minguettes in Vénissieux in the south of the metropolitan area. During the interview, these social housing complexes were called by experts as the most disadvantaged and criminalized in the Metropolis of Lyon, which confirms the author’s hypothesis about the importance of territorial exclusion in the emergence and development of ethnic exclusion.
The feasibility of the victims of corruption's claim for constitutional damages against corrupt public officials in South Africa
Authors: Maseko Thembinkosi W
Published: June 2021

South Africa, just like other countries, is grappling with corruption in the private and public sectors. For this reason, the state has adopted various measures aimed at fighting this scourge. Part of the measures adopted, in this regard, are the legal measures. This article argues that, in addition to the legal measures in place, there is a feasibility for victims of corruption to pursue a claim for constitutional damages arising from corruption by public officials. This contention is based on the fact that constitutional damages is an appropriate remedy for corruption cases involving public officials.

Authors: Williams Katherine , Werth Eric
Published: June 2021

Students acting as content creators is an emergent trend in the field of open educational practice. As more faculty turn towards the use of open pedagogy or OER-enabled Pedagogy, they must be prepared to address concerns related to intellectual property rights of student work. This article addresses student concerns related to intellectual property rights, specifically related to Creative Commons licensing as well as faculty awareness of use of Creative Commons licensing. Research was conducted at a small, liberal arts college in the Appalachian Region of the United States. All first-year students engaged in an OER-enabled Pedagogy project where they collaboratively created a reader for the First Year Studies seminar course. Following class, students and faculty were interviewed regarding how dynamics of intellectual property and Creative Commons licensing impacted the educational process. Results indicate students are open to sharing their works with credit, and value helping others. Faculty tend to be unfamiliar with Creative Commons licensing and must balance the desire to help students understand licensing and prescribing their own preferences when asked about licensing selection.

Published: June 2021

We study multiple linear regression model under non-normally distributed random error by considering the family of generalized secant hyperbolic distributions. We derive the estimators of model parameters by using modified maximum likelihood methodology and explore the properties of the modified maximum likelihood estimators so obtained. We show that the proposed estimators are more efficient and robust than the commonly used least square estimators. We also develop the relevant test of hypothesis procedures and compared the performance of such tests vis-a-vis the classical tests that are based upon the least square approach.

Francia y la «Revolución española» (1820-1823): ¿un espejo en el que mirarse?
Authors: Basabe Nere
Published: June 2021

El presente trabajo pretende restituir a Francia un lugar en la tradición de las revoluciones liberales de 1820 y sus redes transnacionales, de las que a menudo se ha visto relegada, ampliando así el mapa de la proyección internacional de la revolución española y su Constitución gaditana. Su proximidad y lazos dinásticos no solo vinculaban el destino del Trienio español con los acontecimientos políticos en el país vecino, sino que el estudio de la prensa y las publicaciones del periodo a cargo de destacados intelectuales y hombres políticos demuestra que la discusión en torno a la llamada revolución de España, interpretada casi siempre en clave nacional, marcó el debate público francés del periodo porque Francia tampoco escapó al contacto transfronterizo de revolucionarios y conspiradores, ni a las intentonas insurreccionales de la oposición a la monarquía restaurada, que acabaron con la intervención militar auspiciada por la Santa Alianza
Riego después de Riego: la pervivencia póstuma de un mito heroico liberal en España, Reino Unido, Francia y Rusia (1823-1880)
Authors: Cañas de Pablos Alberto
Published: June 2021

Este artículo busca estudiar el modo en el que sobrevivió el mito liberal en torno a Rafael del Riego después de su muerte en 1823 en España y en otros países europeos dada la gran proyección internacional que tuvo el personaje. Su alzamiento en 1820 en defensa de la Constitución de 1812 se convirtió en emblema de la libertad de todos los períodos posteriores al Trienio Liberal en España. Su humillante final, tanto en su detención y juicio como después de la ejecución por horca en la plaza de la Cebada de Madrid, dio comienzo a una leyenda que sobrevivió, con altibajos, durante décadas dentro del imaginario liberal. Dentro del modelo napoleónico que representó, las obras que elaboraron un culto en torno a él y los actos que lo plasmaron fueron abundantes y variados, además de provenir de contextos geográficos diferentes.
No solo el 23F. El PSOE y la «racionalización» autonómica (1978-1982)
Authors: Rodríguez-Flores Parra Vega
Published: June 2021

La firma de los Acuerdos Autonómicos por parte del PSOE y UCD en julio de 1981 ha sido interpretada tradicionalmente como consecuencia directa del frustrado golpe de Estado del 23F. Este artículo revisa este análisis a partir de documentación interna e inédita, atribuyendo la toma de posición del Partido Socialista, no solo a una reacción frente la intentona involucionista, sino como producto de un proceso mucho más amplio, iniciado tras la aprobación de la Constitución. Los socialistas, condicionados por su trayectoria ideológica, fueron elaborando una política en materia autonómica que estuvo marcada por la coyuntura y que dependió tanto de los avatares del contexto estatal como de los que afectaron a los procesos autonómicos de cada territorio. Cuestiones estratégicas, electorales, ideológicas y una actitud que trataba de conciliar posiciones relativas a la responsabilidad de Estado con el mantenimiento de promesas sobre las demandas de autogobierno, interactuaron retrasando un pacto sobre el que se debatió desde que el nuevo marco legal dejara abierta la nueva estructura del Estado. En esta investigación se analiza la coincidencia entre centristas y socialistas sobre la necesidad de racionalizar la construcción del futuro Estado de las autonomías desde 1979. De hecho, armonizar el proceso autonómico fue un objetivo fundamental en el PSOE mucho antes de que el 23F ofreciera a los socialistas la oportunidad idónea para alcanzar un acuerdo de Estado con el que diseñar un modelo coherente con los principios que el partido había defendido desde el inicio de la Transición.
La Sociedad de Naciones en su centenario: un campo historiográfico en expansión
Authors: Sánchez Román José Antonio
Published: June 2021

Este artículo revisa la historiografía sobre la Sociedad de Naciones desde un período de relativo olvido, tras el final de la Segunda Guerra Mundial hasta la expansión del interés por la organización iniciada en la década de 1990 y que continúa en el presente. El trabajo repasa los temas e interpretaciones que han interesado a los historiadores y las razones que explican la falta de interés durante la Guerra Fría y la explosión de publicaciones en los últimos años. El final del conflicto bipolar, el debate sobre la llamada globalización y las transformaciones en el campo historiográfico con el fuerte impacto de las aproximaciones globales y transnacionales y la renovación de la historia imperial explican en gran medida el creciente interés de los historiadores por la Sociedad de Naciones. Por último, el artículo se plantea brevemente la posible continuidad del boom historiográfico sobre la organización internacional.

Material and methods  The main group included 43 patients who had been diagnosed with LAA thrombosis on the first examination, transesophageal echocardiography, and who showed dissolution of the thrombus on a repeated study performed after 7.1+2.0 weeks of the anticoagulant treatment. The control group consisted of 123 patients with a risk score >0 for men without LAA thrombosis and score >1 for women without LAA thrombosis according to the CHA2DS2‑VASc scale. The patients were followed up for 47.3±17.9 months. The following unfavorable outcomes were recorded: all-cause mortality, ischemic stroke or systemic thromboembolism, hemorrhagic stroke or severe bleeding, and myocardial infarction (MI).

Results Unfavorable clinical outcomes were observed in 39.5 % of patients in the main group and in 3.3 % of patients in the control group (p<0.001). Furthermore, the incidence of ischemic stroke (relative risk (RR), 12.9; 95 % confidence interval (CI), 2.89–57.2), and MI (RR, 5.72; 95 % CI, 1.09–30.1) was higher in the main group. However, the number of MI cases in both groups and the number of stroke cases in the control group increased during the entire follow-up period, while the number of stroke cases rapidly increased only during the first year of follow-up.

Conclusion      In patients with persistent AF, the risk of CVC after LAA thrombus dissolution remains significantly higher than in patients with AF without LAA thrombosis.

Published: June 2021

In this paper, a weighted version of the power Lomax distribution referred to the weighted power Lomax distribution, is introduced. The new distribution comprises the length biased and the area biased of the power Lomax distribution as new models as well as containing an existing model as the length biased Lomax distribution as special model. Essential distributional properties of the weighted power Lomax distribution are studied. Maximum likelihood and maximum product spacing methods are proposed for estimating the population parameters in cases of complete and Type-II censored samples. Asymptotic confidence intervals of the model parameters are obtained. A sample generation algorithm along with a Monte Carlo simulation study is provided to demonstrate the pattern of the estimates for different sample sizes. Finally, a real-life data set is analyzed as an illustration and its length biased distribution is compared with some other lifetime distributions.

As estratégias de marketing são fundamentais em qualquer empreendimento e trata-se de todas as ações que serão utilizadas para divulgar uma marca, produto ou serviço e, consequentemente, atrair mais clientes. O objetivo deste trabalho foi analisar estratégias de comercialização do fubá da paixão produzido com sementes crioulas. Utilizou-se como método a pesquisa de campo, onde a coleta de dados foi realizada através de visitas e aplicação de entrevistas semiestruturadas aos agricultores(as)/feirantes da Feira Agroecológica do munícipio de Remígio, Paraíba. Os produtos derivados do milho livre de transgênico estão atraindo diversos consumidores conscientes e sua comercialização estimula a ampliação do plantio de milho no território da Borborema. Porém, ainda se restringe apenas as cidades circunvizinhas ao Polo da Borborema envolvidas nessa atividade, necessitando da adoção de estratégias que amplie as oportunidades de geração de renda das famílias agricultoras, como maiores investimentos na divulgação e inserção em políticas públicas.

Consciously done exercises are beneficial for human health. However, unconscious and wrong practices (medication use, etc…) can cause various injuries and permanent damage to the human body. For reasons such as increasing muscle mass and/or to getting more performance, taking steroid hormones disrupts overall body hormone balance. Effects of exercise on oxygen and energy metabolism and estrogen as an exogenous steroid have significant effects on the adrenal gland. The aim of this study was to see the effects of 17b-estradiol on surrenal glands of rats that is put through regular physical exercises.

36 male Sprague-Dawley rats between the weights 220-250 gr, were put into thermal-controlled room with day-night cycles to stimulate an optimal day for the subjects. The experiment was modeled by dividing 36 animals into 6 groups in total according to the control, exercising and estrogen administration criteria. Experimental group animals received daily doses of 10 μg/kg/day 17-β-estradiol during 30 days. Also exercises group animals ran at 20 m/min on a 15% grade for 90 minutes and rest 34 minutes. Then, TUNNEL and Hematoxylen & Eosin staining were performed to measure the damage on the adrenal glands.

In group 2, dense presence of degenerative fibroblasts and inflammatuary cells infiltration in zona fasciculata were significantly different. In group 3, the degenerative areas were significant in all adrenal cortex zones. In group 4, necrotic areas were determined in zona reticularis. In group 5, zona fasciculata was severely degenerated. With group 6, Sinusoidal features were completely lost in zona reticularis. The results strongly show that exercise may affect the zona glomerulase in short time period. As a result, exposure to exercise and exercise stress with external administration of estradiol may cause cellular degeneration especially zona fasciculata and zona reticularis in the adrenal gland.
Możliwości wykorzystania aplikacji opartych na grywalizacji i lokalizacji do promowania Sofii jako destynacji turystycznej

Głównym celem artykułu jest określenie możliwości wykorzystania aplikacji opartych na grywalizacji i lokalizacji w miejscowościach turystycznych. Celem szczegółowym jest zbadanie i ewaluacja już istniejących aplikacji tego typu dla Sofii, jak również odkrycie ich potencjału jako narzędzia marketingowego w rozwoju tego miasta turystycznego. Studium opiera się na przeglądzie literatury przedmiotu oraz badaniach kameralnych nad rolą, jaką w promocji Sofii jako destynacji turystycznej odgrywają dostępne aplikacje oparte na grywalizacji i lokalizacji. W ten sposób możliwe było przeprowadzenie analizy porównawczej głównych atrybutów aplikacji, które mają być stworzone w przyszłości. Zastosowano również technikę badań jakościowych, opierając się na wypowiedziach kluczowych informatorów, którzy stanowili eksperckie źródło informacji oraz umożliwili dokładniejsze przyjrzenie się bieżącym i potencjalnym praktykom w tym obszarze badawczym oraz ich skuteczności. Wyniki wskazują, że aplikacje oparte na zasadach gry komputerowej mają ogromne znaczenie dla postępującego zaangażowania użytkowników oraz współtworzenia produktów i usług, jak również dla zwiększania świadomości istnienia tej destynacji. Główne ograniczenia wynikają z faktu, że takie aplikacje są stosunkowo nowym i mało znanym narzędziem marketingowym w dziedzinie turystyki, a brak wystarczającej wiedzy i doświadczenia w ich użytkowaniu powoduje, że nie mogą być wykorzystywane w celach promocyjnych.

Jurysprudencja 5. Prawo prywatne Unii Europejskiej ze stanowiska teorii prawa
Authors: Helios Joanna
Published: June 2021

Głównym celem monografii było zbadanie adekwatności wypracowanych w teorii prawa koncepcji podziału na prawo publiczne i prawo prywatne w prawie Unii Europejskiej. Na marginesie zasadniczych rozważań uwzględniono również dyskusję nad Europejskim Kodeksem Cywilnym, harmonizacją/unifikacją prawa prywatnego i refleksję nad rolą prawa prywatnego w procesie integracji społecznej. W publikacji można wyodrębnić trzy obszary problemowe: 1) adekwatność wyróżnienia prawa prywatnego UE jako rodzaju prawa; 2) kwestię uzasadnienia podziału europejskiego prawa na publiczne i prywatne; 3) modernistyczne uwikłania unijnego prawa prywatnego. Procesy integracji europejskiej oraz globalizacyjne „narzucają” nowe rozumienie prawa publicznego i prawa prywatnego. Wiąże się to ściśle ze zjawiskami: publicyzacji prawa prywatnego, prywatyzacji prawa publicznego oraz multicentryzmem. Na prawo prywatne Unii Europejskiej składa się wiele aktów unijnych o charakterze wiążącym i niewiążącym. Dyrektywy unijne w większości dotyczą obrotu konsumenckiego i są wdrażane za pomocą procedur administracyjnoprawnych, co stanowi pogwałcenie założeń prawa prywatnego. Do prawa prywatnego Unii Europejskiej trzeba również zaliczyć prawo międzynarodowe prywatne. Książka skierowana jest zarówno do teoretyków i filozofów prawa, dogmatyków prawa międzynarodowego i europejskiego, cywilistów, komparatystów i historyków prawa, jak też do wszystkich zainteresowanych prawem prywatnym, które może być szansą dla rozbudowy Wspólnoty.
