Published: March 2021

The results of the analysis of recent military conflicts convincingly show that the forms and methods of the armed forces application are changing and improving. Scientific and technological progress, the rapid development of information technology, the growing role of high-precision weapons, increasing the effectiveness of intelligence, intensive automation of command and control systems change the nature of modern warfare and are having a steady impact on operational arts, including the need to further improve management theory. In modern military conflicts, new trends in the development of an armed warfare have emerged, which affect the construction of the armed forces, the development of forms and methods of their application. At the same time, there are deviations from the classical views on the military operation execution.
The article presents some features of modern conflicts, shows that the main task in modern wars is to gain and maintain information superiority over the enemy through the use of a single information and communication space by the troop’s groupings.

Published: March 2021

In accordance with the strategic course chosen by Ukraine in the Armed Forces of Ukraine, the transformation of the management system based on the principles of joint leadership of the defense forces must be completed. The main purpose of the transformation is to ensure the maximum efficiency of the use of heterogeneous forces and means of the Armed Forces of Ukraine in the interests of the tasks. One of the components of the transformation is the transition to a logistics system. The introduction of logistical approaches to the management of material resources aims to provide in the shortest possible time with minimal costs and losses of military formations (units) with material means.
Therefore, the paper proposes a method for evaluating the effectiveness of logistics operations. The initial data are determined in the method at the first stage.
At the second stage, the hierarchy of the logistics system with the subsystems of management bodies, warehouses with material resources, restoration of weapons and military equipment, provision of the material means, transportation, etc. is presented. However, on the example of the subsystem of material support, priority technical means have been identified that will be used to perform logistics operations using the method of analysis of hierarchies.
At the third stage, applying the method of the maximum element, rationally distributed forces and means of logistics for the timely provision of military formations with material means.
At the fourth stage, to avoid threats that arise on the routes of technical means, taking into account the terrain, road conditions, etc. using the method of dynamic programming determined the rational route of maneuvering technical means during the task.
At the fifth stage, using the method of a progressive standard, a comparative analysis and evaluation of technical means involved in the implementation of logistics operations.

Навколишнє середовище є постійно діючим носієм агресивних корозійних реагентів. В цілому воно в себе включає атмосферне повітря, якій складається з азоту, кисню, водню, вуглекислого та інертних парів, газів та тверді частини (пил). Майже всі компоненті впливають на протікання корозійних процесів.
Деталі сучасних машин виготовляють в більшій частині зі сплаві різних металів. Використання сплавів підвищує міцність виробів, покращує їх знос та інші властивості.
Основним видом руйнування металічних виробів є електрохімічна корозія. Для її протікання необхідні електроліт, якій може утворитись на поверхні деталей у вигляді маленьких краплин атмосферної вологи, а також анодні та катодні ділянки. Анодні та катодні ділянки на поверхні деталей з’являються не тільки за рахунок зіткнення різних матеріалів, але й не однакового ступеню обробки поверхонь. Практично мікрогальванопари виникають всюди, де на металі є краплини вологі.
Найбільш ефективно захист машин від корозії забезпечується шляхом утворення на поверхні деталей механічного бар’єру, але об’єктах бронетанкової техніки існує ряд деталей які неможна покривати маслом, а цілий ряд систем (головним образом радіоелектронна апаратура та оптичні прилади) дуже чутливі до впливу атмосфери і не може бути захищеним маслами. Тому знайшли так званий спосіб обробки навколишнього середовища. Прикладом такого способу може служити герметизація танка та осушення повітря всередині з допомогою силікагелю ( SiO2·3Н2О).
Для осушення повітря в середині використовується силікагель марок МСК та КСМ (кусковий та гранульований), який являє собою висушений гель кремнієвої кислоти.

O presente estudo busca compreender as possíveis implicações da atuação do tutor presencial nos processos de ensino-aprendizagem discentes, considerando os polos de abrangência do Curso de Pedagogia, entre os anos de 2017 a 2019, no âmbito da Universidade Aberta do Brasil (UAB). Essa pesquisa foi realizada através do estudo desenvolvido no Programa de Mestrado Profissional em Políticas Públicas e Gestão Educacional da Universidade Federal de Santa Maria. Inicialmente, realizou-se a sistematização das normativas legais, procurando entender as principais funções do tutor presencial e como elas vinham sendo desenvolvidas no Curso de Pedagogia UAB/UFSM. Buscou-se perceber, a partir do ponto de vista dos sujeitos da pesquisa como as atribuições desses tutores podem influenciar os processos de ensino-aprendizagem dos estudantes. A investigação, de natureza aplicada, ancorou-se em uma abordagem qualitativa, entrelaçando a consulta a documentos e dados empíricos à escuta dos sujeitos envolvidos diretamente com o curso. A coleta de dados envolveu entrevistas semiestruturadas com tutores presenciais e uma escuta dialógica com estudantes de dois polos atendidos pelo curso. Os dados foram analisados a partir da Análise Textual Discursiva, da qual emergiram três categorias: Percepção dos sujeitos acerca das atividades desenvolvidas pelo tutor presencial; Relações/interações entre os sujeitos implicados nos processos de ensino-aprendizagem em EAD, e influência do tutor presencial nos processos de ensino-aprendizagem. Deste cenário de pesquisa, resultou como produto a criação de um ambiente colaborativo de aprendizagem entre os tutores presenciais do curso, utilizando-se da ferramenta eletrônica Padlet.

Aim: This study evaluated the effectiveness of the mechanical reduction of intracanal bacteria produced by the endodontic systems Reciproc Blue (VDW GmbH), XP-Endo Shaper (FKG Dentaire) and ProTaper Next (Dentsply Sirona Endodontics) in severely curved canals by culture analysis. Methodology: Fifty severely curved mesiobuccal canals of mandibular molars were selected and instrumented. Following this, six specimens were selected as control, while 44 canals were contaminated with Enterococcus faecalis strains (ATCC 29212). Specimens were incubated for 21 days at 37 ºC. Then, contaminated specimens were randomly divided into 3 groups (n=14): ProTaper Next (G1), XP-Endo Shaper (G2) and Reciproc Blue (G3). Control Group: Six non-contaminated canals were prepared with one of the 3 file systems (n=2). Microbial samples were obtained before (S1) and after root canal preparation (S2). Two roots were observed using scanning electron microscopy to verify biofilm formation. Quantitative culture analyses of intracanal E. faecalis reduction was performed using CFUs, and the Wilcoxon test was used for intragroup analysis, and intergroup analysis was performed using Kruskal-Wallis test. The level of significance for all analyses was set at P < .05. Results: All systems presented effective bacterial reduction (p<0.05), but still had bacterial growth. ProTaper Next displayed the highest E. faecalis reduction (P<0.05), while XP-Endo Shaper and Reciproc Blue systems presented similar results (P>0.05). ProTaper Next showed the greatest antibacterial action when compared to the XP-Endo Shaper and Reciproc Blue systems. Conclusion: No instrumentation system rendered root canals completely free from bacteria.

Tick saliva is a rich source of pharmacologically and immunologically active molecules. These salivary components are indispensable for successful blood feeding on vertebrate hosts and are believed to facilitate the transmission of tick-borne pathogens. Here we present the functional and structural characterization of Iripin-3, a protein expressed in the salivary glands of the tick Ixodes ricinus, a European vector of tick-borne encephalitis and Lyme disease. Belonging to the serpin superfamily of protease inhibitors, Iripin-3 strongly inhibited the proteolytic activity of serine proteases kallikrein and matriptase. In an in vitro setup, Iripin-3 was capable of modulating the adaptive immune response as evidenced by reduced survival of mouse splenocytes, impaired proliferation of CD4+ T lymphocytes, suppression of the T helper type 1 immune response, and induction of regulatory T cell differentiation. Apart from altering acquired immunity, Iripin-3 also inhibited the extrinsic blood coagulation pathway and reduced the production of pro-inflammatory cytokine interleukin-6 by lipopolysaccharide-stimulated bone marrow-derived macrophages. In addition to its functional characterization, we present the crystal structure of cleaved Iripin-3 at 1.95 Å resolution. Iripin-3 proved to be a pluripotent salivary serpin with immunomodulatory and anti-hemostatic properties that could facilitate tick feeding via the suppression of host anti-tick defenses. Physiological relevance of Iripin-3 activities observed in vitro needs to be supported by appropriate in vivo experiments.

Published: March 2021

Objective: The objective of this study is to evaluate the safety, efficacy, and owner satisfaction following electrosurgical ventriculocordectomy (EVC), in conjunction with prosthetic laryngoplasty, in equine clinical cases affected with left- or right-sided recurrent laryngeal neuropathy.Methods: Retrospective data analysis of clinical signalment, surgery, athletic outcome, intra- and postoperative complications, and postoperative examinations from clinical cases wherein EVC was performed in conjunction with traditional prosthetic laryngoplasty from one practice. Owners were contacted by phone or email for a follow-up questionnaire.Results: Twenty-four horses underwent unilateral EVC, performed transendoscopically under sedated restraint, using monopolar electrosurgical instrumentation successfully. One horse experienced excessive intraoperative hemorrhage. No horses demonstrated postoperative complications. Twenty cases had a history of increased airway noise prior to surgery. In 15 of these cases (15/20, 75%), the airway noise was reported as fully improved post-surgery. Eighteen cases had a history of exercise intolerance prior to surgery. In 15 of these cases (15/18; 83%), the exercise intolerance was reported as resolved.Conclusion: EVC, in conjunction with prosthetic laryngoplasty, can contribute to improvement of RLN symptoms and aid in the effective return to athletic work. Performing transendoscopic ventriculocordectomy with monopolar electrosurgical instrumentation provides comparable clinical outcomes to traditional techniques using a diode laser or direct excision via laryngotomy.

Can Covid-19 in Wastewater Be Removed by Membrane Processes? A brief review
Authors: YILDIZ Yasemin 
Published: March 2021

The world has faced many factors that cause pandemics for a century. There have been three major epidemics caused by coronaviruses in the last 17 years. The most recent outbreak, COVID-19, WHO announced outbreak from epidemic to global pandemic on March 11. More effort is needed to understand why they occur in different enviromental and the frequency of these outbreaks. When looking at the evidence based on wastewater, it is seen that the interest in the presence of coronavirus in wastewater has increased. Even if a broad study of information on the fate and possible contamination of the coronavirus in wastewater is not yet available, there is a few review with coronavirus in wastewater.
This article is the purpose of reviewing the literature regarding the emergence of coronaviruses in wastewater treatment processes. We discussed the literature on the presence, survival, and possible elimination of coronaviruses in common wastewater treatment processes. We also struggle to keep questions on the agenda about potential infection risks for people exposed to untreated sewage / wastewater. Therefore, we focused on the potential risk of coronavirus infection for workers in wastewater treatment plants and the public due to sewage networks.
