Authors: Veeramalini J B , Baskar G , Sheeja N.
Published: May 2020

A series of 3-ethyl-2,6-diarylpiperidin-4-one thiosemicarbazone and 3,5-dimethyl-2,6-diarylpiperidin-4-one thiosemicarbazone were synthesised. The thiosemicarbazones were subjected to cyclic voltammetric study using graphite electrode with variable scan rate at moderate acidic conditions maintained in the electrolytic solution. The reduction takes place by two electron transfer and the reaction is pH dependent. The reduced products were isolated and purified by column chromatography. The structure was proved by 1H and 13C NMR spectroscopy. The electrode process was found to be irreversible and diffusion controlled. Further the products were analysed for anti fungal activity in which nitro substituted compound showed high inhibition towards the fungi Asperillus niger

Authors: Arulraj M. , Palani P.K. , Venkatesh L.
Published: May 2020

Aluminium based composites exhibit many attractive material properties such as increased stiffness, wear resistance, specific strength and vibration damping and decreased co-efficient of thermal expansion compared with the conventional aluminium alloys. Aluminium Matrix Composites consist of non-metallic reinforcement which offers advantageous properties over base material. Reinforcements like SiC, B4C and Al2O3 are normally preferred to improve the mechanical properties. Here Aluminum LM25 is selected as matrix material while Silicon carbide and Boron carbide are selected as reinforcement material. The fabrication of aluminium matrix was done by stir casting method. In the present study an attempt has been made to investigate the effect of three major stir casting parameters (stir speed, stir duration and preheated temperature of reinforcement material) on stir casting of Aluminium LM25 - SiC - B4C composite. Experiments were conducted based on Taguchi methodology. Taguchi quality design concepts of L9 orthogonal array has been used to determine S/N ratio and through S/N ratio a set of optimum stir casting parameters were obtained. The experimental results confirmed the validity of Taguchi method for enhancing tensile strength of castings.

Published: May 2020

Eksplorasi metode gravitasi umumnya dilakukan untuk mencari objek di bawah permukaan yang dangkal sehingga perlu dilakukan pemisahan anomali residual dan regional dari anomali Bouguer lengkap. Perhitungan anomali residual biasanya menggunakan software khusus untuk pengolahan data geofisika yang berlisensi atau algoritma dengan bahasa pemrograman, sedangkan program Microsoft Excel pada PC dan notebook biasa digunakan untuk perhitungan polinomial pada pengolahan data statistik. Penelitian ini memperkenalkan cara menghitung anomali residual menggunakan Microsoft Excel dengan filter polinomial. Hasil validasi yang menggunakan model sintetik menunjukkan bahwa perhitungan tersebut dapat diaplikasikan pada data metode gravitasi. Aplikasi pada data lapangan diperoleh bahwa anomali residual berfrekuensi tinggi, sedangkan anomali regional berfrekuensi rendah. Nilai anomali regional dipengaruhi oleh trendline anomali Bouguer lengkap dalam domain jarak. Hasil ini relatif sama dengan hasil perhitungan software lainnya. Gravity method exploration was generally conducted to seek the object in shallow underground so that required residual and regional anomaly separation of complete Bouguer anomaly. The residual anomaly separation was usually used by the special softwares for geophysics that require licency or algorithm by programming language, however the program of Microsoft Excel in the PC or notebook was usually applied to compute the polynomial filter for statistic data analysis. This research introduces how to compute residual anomaly using Microsoft Excel through polynomial filter. The validation result of sintetic model shows that the computation using Microsoft Excel can be applied to gravity method data. The application of field data was obtained that residual anomaly has high frecuency, whereas residual anomaly has low frecuency. The value of regional anomaly was influenced by trendline of complete Bouguer anomaly in distance domain. This result relatively equals to the result of other softwares. Keywords: gravity method, residual anomaly, regional anomaly, polynomial filter, Microsoft Excel

Defining wicked problems for public policy: The case of Mexico’s disappearances
Authors: Naime Monica
Published: May 2020

Wicked problem literature is increasingly popular, but empirical studies about its relation to public policy are scarce. Additionally, there is no consensus on the convenience of Public Administration as policy makers addressing wicked problems by artificially defining and structuring them. The purpose of the paper is to address these gaps, specifically how, in practice, governments handle wicked problems. Two possible alternatives are discussed: either policy makers are rational, or rather they use heuristics for problem definition. The research focuses on problem definition as part of the policy process. In particular, how the definition of the particular wicked problematic situation was reflected in legislation: disappearances in Mexico. The case shows that forced disappearances is an heterogeneous phenomenon that can be considered a wicked problem, which further increases the complexity of policies that aim to tackle it. Also, results of applying congruence tests show that policy-makers structure wicked problems when defining them, but after a certain amount of energy has been spent on this task, policy makers employ heuristic devices. This contributes to understand how flesh and bone decision-makers build public policies.

Desde el inicio de la administración de Donald Trump, se ha percibido en el mundo una atmósfera de especulación acerca de las consecuencias de las políticas actuales de Estados Unidos, especialmente en materia de comercio exterior. En 2018, nuevas tendencias proteccionistas han puesto en cuestión las propias iniciativas que rigieron el comportamiento de ese país en gran parte de los últimos dos siglos.    El periodo inaugurado por el líder marcó un hito en la historia reciente, con efectos aún no totalmente predecibles, pero que dan continuidad a otros fenómenos contemporáneos. Algunos de ellos fueron los cambios de la estrategia que desarrolló EE. UU. a partir de los atentados del 11 de septiembre del 2001 y luego de la crisis de las economías occidentales en 2008.

It is established that the development of beekeeping practice and entrepreneurship based on production of honey relates to the functionality of the network structures.
Economy of distributed use as the base for organizational-economic mechanism of managing regional property
Authors: Kolmakov Vladimir Vladimirovich
Published: May 2020

The subject of this research is the organizational-economic mechanism of managing regional property as a combination of means and methods of achieving goals of the managing system regarding the collectivity of managed objects and subjects, based on the objective economic laws and social processes in the set institutional conditions. The indicated mechanisms are studied from the perspective of their transformation and mutual influence. Special attention is given to such modern organizational-economic mechanism of managing regional property as distributed use of the elements of the regional property complex. It is substantiated that distributed use as a promising organization-economic mechanism of managing regional property allows achieving an economic effect by transition towards network forms of organization of the economic space. Assessment of the economic effect, which is based on imitation modeling of the change in net result of economic activity of the subjects from various regions, in increasing volume of production as a result of implementation of measures on stimulation of the internal demand by the regional authorities, demonstrates that application of distributed use as a mechanism of managing regional property ensures increase in net result of economic activity by an average of 4.4%, while expanding investments into the main capital with set parameters dilutes the net result by an average 0.9%. The regions can also gain additional economic effects from increase in revenue and economy on the costs of proprietors transferred into distributed use of production capacities.

Authors: Kozlova Elena Ivanovna , Novak Maksim Andreevich
Published: May 2020

The demographic trends in social development have a basic foundation with regards to any other trends. Therefore, the management solutions aimed at rising birth rate, increasing longevity of life, and optimization of migration flows become an integral part of the federal and regional development strategies. Growing depopulation of the country actualizes studying of the problem of demographic development. The goal consists in substantiation and determination of the problematic aspects in the priority vectors of demographic development and tools of their implementation included into the Strategy of Socioeconomic Development of Lipetsk Region for the period until 2024. Analysis is conducted on the dynamics of demographic processes in Lipetsk Region for the period from 01.01.2017 to 01.01.2019. The author assesses the possibility of achieving target indicators of the regional development strategy by natural decline in population and size of population of Lipetsk Region of working age. The conclusion is substantiated on the inaccurate determination of regional demographic trends by the authorities in the current cycle; weak response to the regional demographic situation by making management decisions. The author proposes to modify the formulation of the goal of development strategy of Lipetsk Oblasts in demographic sphere.
Rozwój instytucji przysposobienia a tożsamość dziecka. Konsekwencje prawne i dylematy etyczne
Authors: Rakoczy Tomasz
Published: May 2020

The Polish family law has developed three types of adoption: incomplete, full and total. Each of them is a reply to the arising new threat of the good of the child. Simultaneously each of them indeed influences the identity of the child. As a result of the preparation a civil status of the child is changing. The adoption is connected with secrecy. Originally it was firmly stressed. At present the doctrine as well as practitioners think that holding on to secrecy is not necessarily purposeful. The presented legal structures give rise to a series of ethical dilemmas. Firstly, the question arises about supporting biological parents in leaving the child in their family. The law does not regulate such efforts. It only orders “to wait” six weeks for making the decision on adoption by the mother of the child. Secondly, the similar question arises on the part of adopting parents. What motivation do they have? Is this good of the child or their own good alone? Is combining these goods in one act possible? Also the question arises with reference to respecting the religious membership of the child. As a result of the adoption the surname of the child is changed. Even a change of the child’s first name is possible. The religious identity remains unchanged. The practice shows that family relations with the adopted child are not always successful. The rich case law proves that resolving adoption is not always possible.

Published: May 2020

The article deals with the problem of limitation of liability for bequests in Roman law in the period of the Republic. The laws were discussed, on the basis of which the Roman legislator in the time of the Republic, tried to create a real incentive to accept an inheritance, even if overburdened with bequests. The lex Furia testamentaria, lex Voconia, and lex Falcidia were presented in detail, the aim of which was to enable heirs to retain minimum proportion of the estate. In addition, as part of favor testamenti, as well as showing respect for the testator’s last will, they attempted to prevent the invocation on the basis of the provisions of the Act, where the valid will existed.

Synopsis

High-quality sports injury research can facilitate sports injury prevention and treatment. There is scope to improve how our field applies best-practice methods–methods matter (greatly!). The first METHODS MATTER meeting, held in January 2019 in Copenhagen, Denmark, was the forum for an international group of researchers with expertise in research methods to discuss sports injury methods. We discussed important epidemiological and statistical topics within the field of sports injury research. With this opinion document, we provide the main take-home messages that emerged from the meeting. Meeting participants agreed that the definition of sport injury depends on the research question and context. It was considered essential to be explicit about the goal of the research effort and to use frameworks to illustrate the assumptions that underpin measurement and the analytical strategy. Complex systems were discussed to illustrate how potential risk factors can interact in a nonlinear way. This approach is often a useful alternative to identifying single risk factors. Investigating changes in exposure status over time is important when analyzing sport injury etiology, and analyzing recurrent injury, subsequent injury, or injury exacerbation remains challenging. The choice of statistical model should consider the research question, injury measure (eg, prevalence, incidence), type and granularity of injury data (categorical or continuous), and study design. Multidisciplinary collaboration will be a cornerstone for future high-quality sport injury research. Working outside professional silos in a diverse, multidisciplinary team benefits the research process, from the formulation of research questions and designs to the statistical analyses and dissemination of study results in implementation contexts. This article has been copublished in the British Journal of Sports Medicine and the Journal of Orthopaedic & Sports Physical Therapy.

Oil and gas fuel from unconventional types of reservoirs was the development of alternative sources in addition to oil and gas fuels from conventional type reservoirs that can be obtained to meet domestic needs. The development of unconventional oil and gas reservoirs has developed rapidly outside Indonesia, such as in North America and Canada. One type of unconventional oil and gas reservoir was obtained from shale rock reservoirs. Hydrocarbon shale produced from shale formations, both source from rock and reservoir. This unconventional hydrocarbon has a big potential to be utilized. In this study, an analysis of the development of unconventional oil and gas from Shale Hydrocarbons carried out in Indonesia. This research included the distribution of shale reservoir basins, the number of unconventional shale reservoir resources, factors affecting the development of unconventional oil and gas in shale reservoirs in Indonesia, efforts made by the government to promote exploration activities, exploitation of shale reservoirs in Indonesia, and existing regulations for non-conventional oil and gas. The development of unconventional oil and gas reservoir shale needed to be developed immediately and will attract investors to meet domestic needs for renewable energy needs. From the geological data obtained, there were 6 basins and 11 formations that analyzed for commercialization. Tanjung and Batu Kelau Formation was a prospect formation from 4 desired data categories. In terms of regulation, it still needed improvement to increase the interest of upstream oil and gas entrepreneurs in the unconventional oil and gas shale reservoir. Research in the field of unconventional oil and gas exploitation technology for hydrocarbon shale needed to be improved.

[EN] Lampung, a province where Institut Teknologi Sumatera (ITERA) is located, is an area that has a high level of seismicity. This research takes a case study of the Building E ITERA which has a dilatation building concept. Due to dilatation, inter-buildings have the risk of collisions because of earthquake loads. The purpose of this study is to determine the value of joint displacement in adjacent buildings when given a dynamic load of Time History and determine whether the adjacent buildings experience a pounding effect. A Time History earthquake load data that has been matched with the Lampung region response spectrum by software is applied to the model of Building E. Building E is modeled according to the as built drawing data and the results of field checking. Structure is analyzed using software. The results of the study showed that the structure of the Building E which was loaded by Loma Prieta earthquake that has been matched would experience inter-building collisions. Further research using earthquake record data taken in areas within certain radius from ITERA is need to be conducted to obtain more accurate results.
Detrimental effects of tax havens and the case of the Dutch tax system
Authors: Wágner Tamás Zoltán
Published: May 2020

Nowadays, multinationals have become so strong that they can easily compete with states. Consequently, they have the opportunity to develop several tax minimalization strategies such as transfer pricing, inversion, hybrid entities etc. All these have a negative impact on the world economy and state budgets. Despite detrimental effects, certain countries try to cooperate with multinationals by transforming themselves into tax havens. In this framework, they provide multinationals with various kinds of tax advantages such as deductions, low tax rates and preferential tax rulings (“sweetheart deals”). Although, the general attitude towards tax avoidance in the European Union is negative, particular member states’ tax systems display several characteristics of tax havens. In this regard, it should be noted that multinationals regularly use the loopholes and other advantages of the Dutch tax system to minimise their tax liability. The following study – after a brief view to the characteristics of tax havens– will illustrate these options by highlighting the fact that the country – despite the denial of the respective governments – still displays several characteristics of - tax havens.

Although the security benefits these technologies offer security benefits to our society, their widespread application can involves and clearly leads to serious legal issues and concerns, including technological encounters, disputes and grave concerns for individual citizens’ rights of privacy. Various forms of identification, such as driving licenses, passports, and other identity cards, are progressively being combined with biometric information used by ever-changing and more advanced systems. With no doubts, it can stated as well that the use of them will be spread to other sectors too. Therefore, It safe to assume that this noticeable prosperity of personal information will involve and ache for more advanced data protection measures, encryption technologies, and other safeguarding measures, both to inspire their acceptance and use by the civilian population and to keep this critical information from falling into the wrong hands.

A abordagem metodológica dos conteúdos propostos pela sequência didática é estruturada com base no perfil dos investigados, que são alunos da disciplina de Materiais Elétricos e Magnéticos do curso de Bacharelado em Ciência e Tecnologia. Elaborou-se um esquema sequencial de um currículo de curta duração com propostas de aula expositiva, atividades virtuais do aplicativo em questão, bem como a elaboração extra-sala de um projeto elétrico residencial simplificado. Os resultados obtidos nessa pesquisa comprovaram a eficiência didático-pedagógica da proposta, a qual permitiu ao professor o acompanhamento das produções dos estudantes durante todas as etapas exercidas em sala de aula. Os estudantes atingiram níveis satisfatórios na aprendizagem dos conteúdos, bem como na apropriação técnica de uma aplicação real dos conceitos estudados, que é a elaboração de um projeto elétrico residencial.

Published: May 2020

No presente artigo nos propomos a discutir sobre a formação inicial de professores de Ciências e Matemática, com o intuito de indicar potencialidades e fragilidades de uma proposta de formação interdisciplinar posta em ação. Apresentamos um estudo, fruto de uma tese defendida em 2018, realizado com 64 egressos do curso de Licenciatura em Ciências Naturais e Matemática (LCNM) da Universidade Federal de Mato Grosso, Câmpus Universitário de Sinop. A pesquisa apresenta uma abordagem quali-quantitativa, que analisa os dados produzidos por meio de um questionário aplicado a egressos do curso. A diversidade de percepções apresentadas em relação ao percurso formativo vivenciado no curso de LCNM demonstra que não há consenso entre seus egressos. Identificamos que a proposta de curso de LCNM apresenta características inovadoras, bem como potencialidades, a exemplo da aproximação de professores de diferentes áreas e o favorecimento de articulação do conhecimento no currículo. No entanto, possui elementos que necessitam ser problematizados, como a carga horária, o tempo do curso e sua ampla habilitação, que é apontada tanto como o potencial e a fragilidade do curso. Enfatizamos que a formação inicial de professores é um desafio a ser superado e torna-se necessário analisar o conhecimento sistematizado, oriundo de propostas já implementadas, com o intuito de identificar potencialidades e fragilidades do processo formativo.

Published: May 2020

A formação em nível stricto sensu no Brasil ocorreu, por muito tempo, nos grandes centros, sobretudo nas regiões Sul e Sudeste. A Rede Amazônica de Educação em Ciências e Matemática (REAMEC) tem contribuído para mudar tal cenário, formando doutores para a região da Amazônia Legal. A pesquisa realizada teve como objetivo analisar como a REAMEC proporcionou mudanças na carreira profissional do doutor egresso, e analisar as percepções dos egressos em relação à formação obtida no processo de doutoramento. A abordagem da pesquisa é de cunho qualitativo, descritivo e exploratório, tendo como instrumento de produção de dados entrevistas e levantamento na plataforma Lattes com informações dos currículos dos egressos da turma 2011. A análise das entrevistas   foi elaborada mediante análise de conteúdo de Bardin. Com os dados obtidos nas entrevistas, três categorias emergiram: satisfação acadêmica, financiamento e oportunidade de permanência na Amazônia Legal. A REAMEC formou 130 doutores até dezembro de 2019, e os entrevistados deste estudo mostraram-se   satisfeitos com a formação recebida e narraram   como a rede foi importante em sua trajetória profissional e de igual importância foi a sua formação ter ocorrido na região na qual atuam. O estudo possibilitou mostrar que a REAMEC é um programa consolidado na região e que  possibilita, a passos largos, a constituição de grupos de pesquisas e programas de pós-graduação na área.

2­ci tip səkərli diabeti olan xəstələrdə ümumi yuxu arteriyasının (ÜYA) intima­media kompleksinin qalınlıgına (İMKQ) müx­ təlif risk amillərinin (hiperqlikemiya, hiperlipidemiya, arterial hipertenziya (AH), siqaret çəkmə) təsirini öyrənmək məqsədilə orta yaşı 58±15,2 yaş olan və şəkərli diabetin müddəti 9,8±7,4, AH­nın müddəti isə 15,6±4,9 olan 60 xəstə (26 kişi və 34 qadın) müayinə olunmuşdur. Bütün xəstələr stasionar fiziki müayinədən, elektrokardioqrafiya, exokardioqrafiya, ekstrakranial damar­ ların duppleks skanlaşması prosedurlarından və risk amillərinin qiymətləndirilməsindən keçmişlər. Acqarnına qlikemiyanın, postprandial qlikemiyanın, lipid spektrinin göstəricilərinin səviyyəsinin dinamikası qiymətləndirilmişdir. Alınan nəticələr onu göstərir ki, ÜYA­nın İMKQ­nın ultrasəs müayinəsi 2­ci tip şəkərli diabeti olan xəstələrdə damar divarının vəziyyətinə müxtəlif aterogen risk amillərinin (mexaniki – AH; biokimyəvi – dislipidemiya; hiperqlikemiya; toksiki – siqaret çəkmə) mənfi təsirinin qiymətləndirilməsi imkanını verir. Bu isə gələcəkdə aterosklerozun profilaktikası üçün muasir aktiv tədbirlərin aparılmasına şərait yarada bilər və xəstəliyin proqressivləşməsini zəiflədə, damar agırlaşmalarının tezliyini əhəmiyyətli dərəcədə azalda bilər.

Первый и повторный мозговой инсульт: клинико­патогенетические соотношения
Authors: Gafurov B.G.
Published: May 2020

На материале клинического и лабораторно­инструментального исследования 81 случая повторного (63 ­ после первого ишемиче­ ского и 18 ­ после первого геморрагического) инсульта изучены клинико­патогенетические соотношения между первым и повтор­ ным его вариантами. Выявлена тенденция к локализации очага повторного инсульта в том же полушарии в случае неизменности его клинической формы, по сравнению с первым инсультом, и локализации очага в другом полушарии, при изменении клиниче­ ской формы (ишемический на геморрагический и наоборот). Среди патогенетических типов ишемического инсульта наиболее ста­ бильными при повторном его случае (по сравнению с первичным) оказались лакунарный и гемореологический типы, при осталь­ ных вариантах патогенез повторного инсульта менялся чаще. Сделан вывод, что дальнейшие исследования в этом направлении помогут в решении вопросов прогнозирования повторных инсультов и улучшения результатов вторичной профилактики.
On the Characteristics of Ground Motion and the Improvement of the Input Mode of Complex Layered Sites
Authors: Pan Hongke , Jiang Xinxin
Published: May 2020

It is a hot research topic to perform the dynamic interaction analysis between the engineering structure and the soil by using the time-domain method. This paper studies the seismic behaviour of the layered sites and the seismic response of the structures using the viscous-spring artificial boundary theory. The artificial boundary model of viscous-spring is initially based on homogeneous foundation. For the layered site (Foundation), the traditional homogeneous model or equivalent load input mode is not suitable, which may bring great error. By introducing the changes of coefficients and phases of reflection and transmission of seismic waves at the interface between layers, an improved method of equivalent load input mode of traditional viscous-spring artificial boundary model is proposed. This new wave model can simulate the propagation law of seismic wave in layered site more accurately, which is available for the seismic performance of engineering structure under the condition of large and complex layered site. At last, the simplified homogeneous model, the equivalent load input method and the improved layered model input method are used to study the seismic response of the engineering example. It is shown that the results calculated by the three methods are different, which shows that the homogeneous foundation model and the conventional equivalent load input method of seismic wave cannot simulate the seismic force accurately, whereas the improved wave input model can better reflect the characteristic of traveling wave in layered sites.

This paper presents a study to investigate the behavior of post-tensioned segmental concrete beams that exposed to high-temperature. The experimental program included fabricating and testing twelve simply supported beams that divided into three groups depending on the number of precasting concrete segments. All specimens were prepared with an identical length of 3150 mm and differed in the number of the incorporated segments of the beam (9, 7, or 5 segments). To simulate the genuine fire disasters, nine out of twelve beams were exposed to a high-temperature flame for one hour. Based on the standard fire curve (ASTM – E119), the temperatures of 300◦C (572◦F), 500◦C (932◦F), and 700◦C (1292◦F) were adopted. Consequently, the beams that exposed to be cool gradually under the ambient laboratory condition, after that, the beams were loaded till failure to investigate the influence of the heating temperature on the performance during the serviceability and the failure stage. It was observed that, as the temperature increased in the internal layers of concrete, the camber of tested beams increased significantly and attained its peak value at the end of the time interval of the stabilization of the heating temperature. This can be attributed to the extra time that was consumed for the heat energy to migrate across the cross-section and to travel along the span of the beam and deteriorate the texture of the concrete causing microcracking with a larger surface area. Experimental findings showed that the load-carrying capacity of the test specimen, with the same number of incorporated concrete segments, was significantly decreased as the heating temperature increased during the fire event.
