Published: June 2020

The study assessed the perceptions of stakeholders on factors causing sports facilities defects in selected universities established between 1957 and 1962 in South-West Nigeria by examining the strength of the identified factors responsible for sports facilities’ defects in the selected universities. Data were collected using a structured questionnaire which was administered on sports men and women and maintenance personnel. The study incorporated all the fifteen sports featured at the Nigeria University Games Association (NUGA) competitions. Three federal universities were purposively selected because these have facilities for all the fifteen sports and have hosted national and international sporting events. Data obtained were analysed using frequency distribution, percentages, mean response analysis and factor analysis. Using the mean response analysis, the result showed that the most severe factors responsible for sports facilities’ defects were design deficiencies (3.67), intensity of use (3.53), level of exposure to climatic condition (3.41), inadequate maintenance funding (3.19), vandalism (3.18), moisture (3.17) and inadequate cash flow analysis (3.16). The study recommends that users of the facilities should be carried along at the designs stage to minimize design errors and also adequate fund should be provided to maintenance unit to guarantee adequate maintenance of sports facilities for optimal performance.
O grze interpretatora z tekstem prawnym i czynnikami pozatekstowymi w derywacyjnej koncepcji wykładni prawa
Authors: Jabłoński Paweł , Kaczmarek Przemysław
Published: June 2020

The aim of this paper is to show the derivative concept of legal interpretation from the point of view of the structure of limits of the juridical power. This structure includes the politico-legal culture, the legal text, the juridical culture, and personal factors, such as ethical and aesthetic judgements.

These days, the derivative concept is the most influential Polish theory of legal interpretation. According to this concept the process of interpreting the law is a kind of a game between the legal text and extratextual factors, which are treated as extratextual limits of juridical power. On the one hand, the legal text does not determine the full meaning of the law, although it has great importance for it. On the other hand, the derivative concept precisely identifies certain others factors that are relevant for the content of law.
O wykładni prawa i jej wymiarze praktycznym. Kontekst sądowego stosowania prawa
Authors: Leszczyński Leszek
Published: June 2020

The aim of the study is to identify those aspects of legal interpretation which may strengthen its practical dimension. The operative interpretation, distinguished in the theory of law, needs to be developed, inter alia, in order to strengthen the legal discourse as a whole and to contribute to better communication and deeper integration between dogmatic and theoretical legal studies. As a result, the theory of interpretation itself would become more complete. Three most important aspects of giving a practical dimension to various interpretive approaches are analysed in the paper. The first of them is the use of the so-called decision-making character of the operative interpretation, when such interpretation is made in connection with the findings of fact, which limits its scope, while at the same time broadening the number of the established normative bases for decisions, and also in the context of the subsequently-formulated justification of the interpretative decision. The second one is its validation-derivative approach, indicating the phases of operative interpretation, the multiplicity of carriers of law taken into account and the distinction of roles played at particular phases by the each type of rules of interpretation. Finally, the third aspect points to the need to include operative interpretation in the comparative approach, the main determinant of which are the differences of interpretation in particular branches of law.

Authors: JAMHIRI Babak
Published: June 2020

Loose sands are susceptible to the earthquake due to lack of strength and even saturated sands may experience liquefaction. To address problems in loose fine sands, in this article, hydrated lime and zeolite as one of the pozzolanic methods for soil improvement are instrumented together to improve fine sandy soils’ compaction properties. To provide aid for practical compaction of fine sandy soils, physical properties of treated soils with 3, 4 and 5 percent of lime and 8, 10 and 12 percent of zeolite are investigated. A series of Proctor tests, Specific Gravity of soil’s solids and Minimum Index Density was performed to obtain maximum dry density and index void ratios. Additionally, the hydration rate of zeolite is modeled by Arrhenius method to quantify the effective duration of hydration process. Results showed that application of zeolite led to a better compaction property while treated soils only with lime did not show any improvement.

Published: June 2020

The acoustic loads arising during the operation of the launch vehicle are sources of in-tense vibration of its components. Basically these loads are caused by such factors as the propulsion system operation during the launch vehicle start and by oscillatory processes in a turbulent boundary layer during the launch vehicle flight. In this regard, industry normative documentation prescribes evaluating dynamic tests of the launch vehicles and autonomous tests of rocket and space equipment.These tests confirm the dynamic strength and performance of launch vehicle components. This paper presents the results of the vibroacoustic loads analysis for the dry compartments of the mid-range launch vehicle currently being designed, depending on their construction, the attachments weight and the external load, which was set both in the form of acoustic load when solving a coherent elastic and acoustic task, and in the form of harmonic pressure, equivalent to acoustic.

Published: June 2020

The split-type conical nozzles with replaceable exit sections with diameters of 30, 40 and 50 mm were designed and produced from steel by machine turning. In addition, the replaceable output parts of the nozzles with the same diameters were produced by additive technology (fused deposition manufacturing) from ABS plastic. In the acoustic anechoic chamber, the noise measurements of a single-stream cold air jet for all the nozzles at jet velocities in the range of 0.3-0.7 Mach numbers were carried out. The noise measurements were performed on distance of 2 m from the center of the nozzle exit section at angles from 30 to 105o. For different directions of noise radiation and different velocities of the jet, the power spectral density and overall sound pressure level were determined. The obtained results demonstrates that the jet noise for nozzles with diameter of 40 and 50 mm from steel and ABS plastic differs by no more than 1 dB, which is within the measurement error for these types of experiments. The nozzles with diameter 30 mm have a higher difference in noise, which can be explained by the more sensitivity of a nozzle with a small diameter to the deviations of geometric parameters when it produced by additive technology.
ENVIROMENTAL ASPECTS OF NOISE ASSESSMENT AND REGULATION IN THE DESIGN OF PORT COMPLEXES IN RUSSIA
Authors: Zhigulski Vladimir , Zhigulskaya Daria , Shuisky Vladimir , Chebynina Ekaterina , Panichev Vitaly
Published: June 2020

A comparative analysis of various biological objects sensitivity to acoustic effects is being conducted. For many animal species, the frequency range at which sounds are heard is very different from that for humans and may not even intersect with it. The total frequency range at which various animals can hear covers at least eight orders of magnitude (from hundredths of Hz to hundreds of kHz), while for humans this interval is limited to only four orders of magnitude. Thus, the existing anthropocentric standards for permissible noise levels are unsuitable for regulating their impacts on natural ecosystems and it is necessary to develop standards for sound pressure levels in the entire specified frequency range that are acceptable for the most sensitive recipients. For terrestrial and riparian ecosystems and protected areas, natural test subjects are birds, for which noise levels of 35-40 dBA do not cause pathological changes in behavior and physiological processes. This level can tentatively be considered as maximum permissible for man-made noise and for the noise of ports in particular. More reliable results will be given by regulating the permissible sound pressure levels in the entire frequency range based on reactions of the most sensitive recipients in each octave.

Understanding milling tandem control
Authors: Kent Geoffrey A.
Published: June 2020

Considerable work has been done over the years to automatically control the operation of the milling tandem. Control can be achieved by utilising relatively simple algorithms. Chute-level control, added-water rate control and speed and torque control of each mill drive are the main elements of the control system. Factory rate control can be achieved by controlling the prepared cane level in the chute of the first mill and controlling the first-mill speed to a set point that may vary depending on factory capacity constraints. Added water rate should vary with the objective of maintaining a relatively constant ratio to the cane-fibre rate, with a potential advantage to extraction by increasing further when pol in cane is high. For rate, performance and protection, the speed of and torque on each milling unit drive should be controlled.

Published: June 2020

New records of the lancelet Branchiostoma lanceolatum from Scottish waters are presented. Most of the records originate from sublittoral monitoring around fish farms from Orkney, Shetland, the Western Isles, the Isles of Skye and Mull, but also from a distillery discharge in the Firth of Clyde and a plankton survey in the Sea of the Hebrides. Lancelets were recovered in sediment grab samples from 6 - 60 m depth. Some recent accounts of intertidal lancelets are also cited. The lancelets appear to prefer coarser sediments and in the fish farm surveys were found predominantly at reference sites, away from the immediate influence of farm deposition.

Informal Sector in India: Migration and Poverty Implications
Authors: Arup Mitra
Published: June 2020

For assessing the role of urbanization in reducing poverty this paper based on secondary datatries to examine the nature of relationship among urbanisation, migration and informal sector employment. Findings suggest that the informal sector also tends to attract migrants as the probability to get work opportunities in this sector could be high. Further, rural and urban poverty are inter-connected as rural to urban migration and informal sector employment and other state-specific characteristics are associated, though migration and urbanisation with its spill-over effects reduce both rural and urban poverty. Also,based onthe survey data for unincorporated enterprises, the paper examinesif the unorganized or informal manufacturing, trade and services have the potentiality to grow and contribute to the realization of the inclusive growth objective. The inter-sectoral linkages do not necessarily mean that productivity and wages improve in the informal sector if the units manage to receive business contract from the formal sector enterprises. In fact, a large body of the informal sector is seen to be unconnected to the formal sector and this independent segment is on the rise over time. Finally the paper argues for the introduction of an informal sector policy which may help reduce the welfare losses to labour employed at the lower rungs.

Introdução: O Frequency-Intensity-Time Index of Kasari avalia a prática de exercício físico em termos de intensidade, frequência e duração, podendo o produto destes parâmetros (FIT) ser como indicador de aptidão cardiorrespiratória.

Objetivo: Avaliar a correlação e concordância do FIT com volume de oxigênio máximo VO2max em medidas direta e indireta.

Métodos: Estudo metodológico com seleção amostral do tipo não probabilística por conveniência, do qual participaram alunos do curso de Instrutores de Educação Física (CI) e membros da família militar (n=59). A amostra foi dividida em dois grupos de estimação do VO2max: protocolo de rampa, utilizando expirômetro (VO2maxrampa), aplicado na família militar; e teste de Cooper (VO2maxCooper), aplicado nos alunos. Todos responderam a mesma versão do FIT. A correlação foi estimada pelo do coeficiente de correlação de Pearson e a concordância foi avaliada por meio do coeficiente de concordância (ρc) e da análise gráfica de Bland e Altman. Os softwares SPSS 15 e MedCalc foram usados.

Resultados: A amostra foi composta por 24 alunos do CI (26,5± 2,39 anos) e 35 membros da família militar (45,28 ± 10,79 anos). Houve correlação significante e fraca apenas entre FIT e VO2maxCooper. Os coeficientes de concordância do FIT foram pobres e desprezíveis entre VO2maxCooper e VO2maxrampa, respectivamente. Os gráficos Bland-Altman exibiram viés de diferença considerável, o que indica margens amplas de sub e superestimação do VO2max.

Conclusão: O Frequency-Intensity-Time Index of Kasari parece ser adequado para descrever de exercício físico praticado, mas o uso do FIT precisa ser melhor investigado.

Published: June 2020

Tyrimo tikslas. Išanalizuoti slaugytojų požiūrį į bendradarbiavimą tarp slaugytojo ir gydytojo anesteziologijoje bei palyginti, kaip vertinimas skiriasi priklausomai nuo išsilavinimo ir darbo stažo. Tyrimas atliktas trijose Kauno miesto ligoninėse, naudojant anketinę „Jefferson Scale of Attitudes toward Physician-Nurse Collaboration“ apklausą. Anketos teiginiai vertinami 1–4 balų intervale pagal Likerto skalę, palankiu laikant >2,5 balų medianą. Rezultatai analizuojami „SPSS Statistics 23.0“ programa, aprašomąja ir ANOVA statistika. Pasirinktas statistinio reikšmingumo lygmuo p<0,05. Tyrimo metu dalyvavo 138 slaugytojai, turintys nuo 2 mėn. iki 47 metų darbo stažą bei skirtingą išsilavinimą: aukštesnįjį, aukštąjį neuniversitetinį, bakalauro arba magistro laipsnį. Slaugytojų požiūriu svarbūs komandinio darbo aspektai: gydytojų dominavimas – 3,08±0,65, slaugytojų savarankiškumas – 3,46±0,54, rūpinimasis pacientu – 3,33±0,56, dalijimasis žiniomis ir bendradarbiavimas – 3,33±0,47 balų (F=12,47; p<0,001). Išvados. Rūpinimąsi pacientu ir slaugytojų savarankiškumą svarbesniais laiko aukštesnį išsilavinimą ir mažesnę darbo patirtį turintys slaugytojai, o gydytojų dominavimą geriau vertina didesnę darbo patirtį ir žemesnį išsilavinimą turintys slaugytojai.

Reaktyvusis artritas yra aseptinis sąnarių uždegimas, pasireiškiantis per 1–4 savaites po ekstraartikulinės infekcijos organizme. Reaktyvusis artritas būna urogenitalinis ir poenterokolitinis [1]. Klinikiniai simptomai pasireiškia staiga ir dažniausiai paveikia kojų sąnarius (kelių, čiurnų). Straipsnyje aprašoma 33 metų pacientės R. P. klinikinis atvejis. Liga prasidėjo po persirgtos žarnyno infekcijos – atsirado nesimetrinis poliartritas. Diagnozė patvirtinta atlikus laboratorinius, imunologinius, rentgenologinius tyrimus. Taikytas gydymas NVNU, GKK rezultatų nedavė, pacientė netoleravo ligą modifikuojamųjų vaistų. Pradėta taikyti biologinė terapija.
«RIGHT ANSWER THESIS», RUSSIAN LAW AND NORMATIVE BASES OF SENTENCING
Authors: Касаткин Сергей Николаевич
Published: June 2020

В статье автор обращается к исследованию «тезиса правильного ответа», предложенного выдающимся американским правоведом Рональдом Майлзом Дворкином (1931-2013). Р. Дворкин высказывал мысль о том, что в развитых правовых системах всегда имеется предзаданный единственно верный ответ на любой юридический вопрос. Актуальность темы исследования связана, с одной стороны, с теоретической фундаментальностью и практической ценностью воззрений американского правоведа, с другой - с их оригинальностью и провокативностью по отношению к традиционным теориям права. Новизна исследования обусловлена малой изученностью данной темы в отечественном правоведении, а равно обращением к проблеме применимости «тезиса правильного ответа» Р. Дворкина за пределами англо-американского права (что составляет основную цель работы). В статье на базе общенаучных методов фиксируются основные позиции и аргументы Р. Дворкина, связанные с «тезисом правильного ответа», изучается его применимость к российскому праву, в том числе к объяснению российского уголовного судопроизводства. Автор высказывает мнение о возможности существования в правовой системе единственно верного ответа, отмечая при этом отсутствие универсальности или необходимости такого положения дел. Подчеркивается некорректность безоговорочного применения тезиса Р. Дворкина как в качестве общего принципа или аксиомы российского права, так и в качестве более частной характеристики нормативных начал и институциональной практики назначения уголовных наказаний.

In the article, the author refers to the study of the « correct answer thesis » proposed by the prominent American jurist, Ronald Myles Dworkin (1931-2013). R. Dvorkin expressed the idea that in developed legal systems there is always a predetermined only correct answer to any legal question. The relevance of the research topic is connected, on the one hand, with the theoretical fundamental and practical value of the views of the American jurist, on the other - with their originality and provocation in relation to traditional theories of law. The novelty of the study is due to the low level of study of this topic in Russian law, as well as the appeal to the problem of the applicability of the « correct answer thesis » by R. Dvorkin outside of Anglo-American law (which is the main goal of the work). The article uses General scientific methods to fix the main positions and arguments of R. Dvorkin related to the « correct answer thesis » , and examines its applicability to Russian law, including the explanation of Russian criminal proceedings. The author expresses the opinion that the only correct answer can exist in the legal system, while noting the lack of universality or the need for such a state of affairs. The author emphasizes the incorrectness of the unconditional application of R. Dvorkin's thesis both as a General principle or axiom of Russian law, and as a more specific characteristic of the normative principles and institutional practice of assigning criminal penalties.
THE MOTIVATIONAL-VALUE SIDE OF THE PERSONALITY AS THE BASIS FOR THE IMAGE FORMATION OF EMPLOYEES OF INTERNAL AFFAIRS
Authors: Никитина Людмила Николаевна
Published: June 2020

В настоящее время авторитет сотрудников органов внутренних дел в обществе невысок. В связи с этим существует реальная потребность в исследовании путей создания положительного образа правоохранителей. В статье уделено внимание исследованию психологических особенностей, влияющих на формирование социально одобряемого образа сотрудников полиции. В ходе исследования были использованы такие методы, как контент-анализ сообщений со средств массовой информации, сравнительный анализ наработок по изучаемой проблеме, групповые беседы, анкетирование, психодиагностическое исследование курсантов и слушателей. Важным аспектом формирования положительного имиджа сотрудников органов внутренних дел является изучение их мотивационно-ценностной сферы. Именно положительная профессиональная направленность и мотивация профессиональной деятельности будут способствовать развитию всех необходимых качеств, отображенных в профессиограмме правоохранителей. Внутренняя мотивация определяет желание самосовершенствоваться, стремление к личностному и профессиональному развитию, предполагает высокую нравственность и законопослушность, а это, в свою очередь, непосредственно отражается на внешне воспринимаемом облике стражей закона. Также на основе результатов исследования разработаны предложения по формированию положительного имиджа сотрудников полиции, касающиеся работы с кадровым потенциалом.

Currently, the public does not appreciate the image of employees of internal affairs agencies. In this regard, there is a real need to study ways of creating a positive image of law enforcement officials. The article focuses on the study of psychological features affecting the formation of a socially approved image of police officers. In the course of the study such methods as content analysis of messages from the media, a comparative analysis of developments on the problem under consideration, group conversations, questionnaires, and psychodiagnostic research of cadets and students were used. An important aspect of the formation of a positive image of employees of internal affairs agencies is the study of their motivational and semantic sphere. It is a positive professional orientation and motivation of professional activity that will contribute to the development of all the necessary qualities displayed in the law enforcement professiogram. Intrinsic motivation determines the desire for self-improvement, the desire for personal and professional development, involves high morality and law-abidingness, and this, in turn, is directly reflected in the outwardly perceived guards of the law. In addition, based on the results of the study, proposals to create a positive image of police officers regarding work with human resources were developed.
Creating a network of importance: The particular effects of self-relevance on stimulus processing
Authors: Schäfer Sarah , Wentura Dirk , Frings Christian
Published: June 2020

Several factors guide our attention and the way we process our surroundings. In that regard, there is an ongoing debate about the way we are influenced by stimuli that have a particular self-relevance for us. Recent findings suggest that self-relevance does not always capture our attention automatically. Instead, an interpretation of the literature might be that self-relevance serves as an associative advantage facilitating the integration of relevant stimuli into the self-concept. We compared the effect of self-relevant stimuli with the effect of negative stimuli in three tasks measuring different aspects of cognitive processing. We found a first dissociation suggesting that negative valence attracts attention while self-relevance does not, a second dissociation suggesting that self-relevance influences stimulus processing beyond attention-grabbing mechanisms and in the form of an “associative glue,” while negative valence does not, and, last but not least, a third dissociation suggesting that self-relevance influences stimulus processing at a later stage than negative valence does.
ARTERY-FIRST APPROACH FOR PANCREATODUODENAL RESECTIONS. SAFETY AND ONCOLOGICAL BENEFIT (LITERATURE REVIEW)
Authors: Ischenko R. V. , Lysenko A. O.
Published: June 2020

The results of treatment of patients with malignant neoplasms of the biliopancreatoduodenal zone remain unsatisfactory. With this localization, pancreatoduodenal resection (PDR) remains the only radical surgical intervention. It is more advisable to start with non-surgical treatment, in the presence of arterial invasion of magistral vessels. This served as an impetus for the development of approaches to determine the presence of tumor invasion in the superior mesenteric artery at the early stage of the operation. The surgical goal of PDR remains to minimize contact with the tumor prior to mobilization and ligation of the supply vessels, as well as to increase the edge of the resection around the superior mesenteric artery. To achieve this goal, a number of researchers have proposed various approaches to the superior mesenteric artery during pancreatoduodenal resection, combined “artery-first approach”.An analysis of the existing artery-first techniques for pancreatoduodenal resections, as well as their effect on the treatment results of patients with periampullary malignant neoplasms, is carried out. When conducting literary searches, the databases Pubmed, Сochrane, EMBASE were used using the MESH keywords “Pancreaticoduodenectomy” in combination with the phrase “artery first”. During this search, 157 articles were found. After further analysis, 53 scientific papers were included in the literature review.Modern studies show a decrease in intraoperative blood loss, a decrease in the frequency of postoperative pancreatic fistulas and gastrostasis, as well as an increase in the frequency of R0 resection when this approach is followed. An unambiguous conclusion about the effectiveness of the artery first accesses when performing pancreatoduodenal resection requires further well-planned randomized clinical trials with a large number of patients.
