Legal Linguistics of Judicial Educational Activities
The objective of the study is to provide characteristics to the state of academic discipline “Legal Linguistics” in Ukraine and in the countries of Romano-Germanic law, and its origin. To achieve the objective, the author has solved the following tasks: 1) description of the state of academic discipline “Legal Linguistics” in Ukrainian educational institutions; 2) “Legal Linguistics” as an academic discipline and as a research direction in the educational institutions of Germany and Switzerland and its importance for training a “European lawyer”.
It has been concluded that “Legal Linguistics” as an interdisciplinary academic discipline must be offered in the curriculum for training a lawyer in the specialty 081 “Jurisprudence” as an academic discipline of choice. The purpose of its study is to get acquainted with the main directions, ideas and problems of the current legal and linguistic science; studying theoretical and methodological principles of legal linguistics; mastering the methodology of drafting, editing and analysis of legal texts, namely normative and legal, various substatutory acts and law-enforcement documents. The tasks of the academic discipline are: students acquire in-depth knowledge, skills and abilities on the role of a language within legal regulation, the basics of legal technique, law-making and law-enforcement errors, specific features of linguistic examination of bills, mastering the methodology of drafting, editing and analysis of legal texts.
The training of a modern lawyer in Europe is increasingly directed not at the study of state legislation, but on the formation of a “European lawyer”, who thinks globally, is able to work not only with national law, but also with the acquis communautaire and to correctly interpret such acts, based on the provisions and conclusions of legal comparative studies. Training of law students in accordance with the European Credit Transfer System, which facilitates their mobility, assists in such a formation
ÉTALE REPRESENTATIONS FOR REDUCTIVE ALGEBRAIC GROUPS WITH FACTORS Spn OR SOn
First Online: 22 May 2018An étale module for a linear algebraic group G is a complex vector space V with a rational G-action on V that has a Zariski-open orbit and dimG = dim V . Such a module is called super-étale if the stabilizer of a point in the open orbit is trivial. Popov (2013) proved that reductive algebraic groups admitting super-étale modules are special algebraic groups. He further conjectured that a reductive group admitting a super-étale module is always isomorphic to a product of general linear groups. Our main result is a construction of counterexamples to this conjecture, namely, a family of super-étale modules for groups with a factor Spn for arbitrary n≥ 1. A similar construction provides a family of étale modules for groups with a factor SOn, which shows that groups with étale modules with non-trivial stabilizer are not necessarily special. Both families of examples are somewhat surprising in light of the previously known examples of étale and super- étale modules for reductive groups. Finally, we show that the exceptional groups F4 and E8 cannot appear as simple factors in the maximal semisimple subgroup of an arbitrary Lie group with a linear étale representation.Dietrich Burde, Wolfgang Globke, Andrei Minchenk
Electrodeposition of Silicon Fibers from KI–KF–KCl–K<sub>2</sub>SiF<sub>6</sub> Melt and Their Electrochemical Performance during Lithiation/Delithiation
The possibility of using Si-based anodes in lithium-ion batteries is actively investigated due to the increased lithium capacity of silicon. The paper reports the preparation of submicron silicon fibers on glassy carbon in the KI–KF–KCl–K2SiF6 melt at 720 °C. For this purpose, the parameters of silicon electrodeposition in the form of fibers were determined using cyclic voltammetry, and experimental samples of ordered silicon fibers with an average diameter from 0.1 to 0.3 μm were obtained under galvanostatic electrolysis conditions. Using the obtained silicon fibers, anode half-cells of a lithium-ion battery were fabricated, and its electrochemical performance under multiple lithiations and delithiations was studied. By means of voltametric studies, it is observed that charging and discharging the anode based on the obtained silicon fibers occurs at potentials from 0.2 to 0.05 V and from 0.2 to 0.5 V, respectively. A change in discharge capacity from 520 to 200 mAh g−1 during the first 50 charge/discharge cycles at a charge current of 0.1 C and a Coulombic efficiency of 98–100% was shown. The possibility of charging silicon-based anode samples at charging currents up to 2 C was also noted; the discharge capacity ranged from 25 to 250 mAh g−1
Unique alternative splice variants of mouse and human 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase-2 mRNA
6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase is a key regulatory enzyme of glucose metabolism. This bifunctional enzyme controls glycolysis and gluconeogenesis as well as glucose phosphorylation and metabolism. 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase-2 (PFKFB-2) plays significant role in the glycolysis regulation in the heart as well as in some other organs (kidney, brain and lung). Results of this investigation clearly demonstrated that in the glioma cells as well as in some mouse organs are presented several new unique alternative splice variants of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase-2. These PFKFB-2 splice variants are a result of deletions or/and inserts in catalytic regions of 6-phosphofructo-2-kinase and fructose-2,6-bisphosphatase as well as in С-terminal regulatory region. Alternative splice variants of PFKFB-2 from glioma and mouse cells contain different inserts after 2nd exon but mouse splice variant has also deletion in 6-phosphofructo-2-kinase region and insert in C-terminus. Another splice variants of mouse PFKFB-2 have deletions in 6-phosphofructo-2-kinase or fructose-2,6-bisphosphatase regions, since one splice variant has deletion of all catalytic domains. In conclusion, this study provides evidences that alternative splicing of PFKFB-2 mRNA possibly has a significant role in glycolysis regulation via creation of monofunctional isoforms of this enzyme
Legal responsibility for vaccination against COVID-19 in Ukraine and other countries
Hromovenko K. Legal responsibility for vaccination against COVID-19 in Ukraine and other countries / K. Hromovenko, R. Minchenko, G. Sarybaieva, Y. Batan, D. Minchenko // Amazonia Investiga. - 2021. - № 10(43). - Universidad de la Amazonia. - P. 264-271. DOI: https://doi.org/10.34069/AI/2021.43.07.26This article analyzes the liability that may arise in case of refusal to receive a COVID-19 vaccine shot, as well as vaccination-related problems in Ukraine and worldwide. We focused on the international and Ukrainian situation regarding the COVID-19 vaccination process. We also considered the legal framework on this issue. The main task of the study was to determine whether
there is a liability, including criminal liability, for refusing to receive the COVID-19 vaccine, the nuances, and the legal basis of this process. The research methodology includes general scientific and special scientific methods, such as systemic, structural, formal-legal, hermeneutic, and methods of analysis and synthesis. We found that COVID-19 vaccination is currently voluntary but
not mandatory in Ukraine. At the same time, according to legal documents, vaccination against several diseases such as diphtheria, pertussis, measles, polio, tetanus, and tuberculosis is mandatory. Practically, this means that those who are subject to such preventive vaccinations may be subject to
sanctions in the form of dismissal for refusing to vaccinate. Only a few foreign countries currently use mandatory COVID-19 vaccination for the entire adult population. More common is mandatory vaccination of certain categories of
workers, including health workers, social workers, essential workers, civil servants, and others who are in close contact with people or whose health and well-being are of particular importance to national security.Стаття аналізує відповідальність, яка може виникнути у разі відмови від щеплення від COVID-19, а також проблеми, пов'язані з вакцинацією в Україні та у всьому світі. Ми зосередилися на ситуації в Україні та світі
щодо процесу вакцинації проти COVID-19. Також, ми розглянули законодавчу базу з цього питання. Основним завданням дослідження було з'ясувати, чи існує відповідальність за відмову в отриманні вакцини від COVID-19, нюанси та правові підстави цього процесу. Методологія
дослідження включає загальнонаукові та спеціальні наукові методи, такі як системний, структурний, формально-правовий, герменевтичний та методи аналізу та синтезу. Ми виявили, що вакцинація проти COVID-19
наразі є добровільною, але не є обов’язковою в Україні. Водночас, згідно з правовими документами, вакцинація проти кількох хвороб, таких як дифтерія, кашлюк, кір, поліомієліт, правця та туберкульоз, є обов’язковою. Практично це означає, що до тих, хто підлягає таким профілактичним щепленням, можуть бути застосовані санкції у вигляді звільнення за відмову від щеплення. Лише деякі іноземні країни наразі
використовують обов’язкову вакцинацію проти COVID-19 для всього дорослого населення. Більш поширеним є обов’язкова вакцинація певних категорій працівників, включаючи медичних працівників, соціальних працівників, працівників найважливіших службовців, державних
службовців та інших, які перебувають у тісному контакті з людьми або чиє здоров’я та добробут мають особливе значення для національної безпеки
