Планирование схемы безопасного движения на морской акватории
Authors: Гриняк Виктор Михайлович
Published: October 2021

Статья посвящена проблеме обеспечения безопасности движения судов на морских акваториях. В условиях насыщенного трафика навигационная безопасность может быть обеспечена только при соблюдении судами определённой схемы движения. В работе ставится задача планирования системы маршрутов (схемы движения) судов через акватории с интенсивным трафиком. Эта схема зависит от географии акватории и особенностей трафика. Выбор того или иного варианта схемы обусловлен необходимостью обеспечения максимальной безопасности движения и практическими соображениями. Особенности задачи затрудняют её прямое решение традиционными методами и средствами, так как они приводят к алгоритмам высокой вычислительной сложности. Так, модельное представление задачи на основе взвешенного графа не позволяет решить ее без привлечения специализированных вычислительных ресурсов. Предложен альтернативный подход: конструирование схем движения экспертным способом из типичных структурных элементов (примитивов) и моделирование движения судов по множеству возможных траекторий с оценкой метрики, описывающей степень опасности движения. В качестве метрики опасности предлагается частота опасных сближений судов, отмечается возможность использования и других метрик. Имитационное моделирование задачи изолированно в рамках отдельного примитива вполне возможно на доступных вычислительных и программных платформах общего назначения. В работе рассмотрены четыре таких примитива, оценено среднее время между опасными сближениями судов для каждого из них. Приведён пример использования полученных результатов моделирования для планирования безопасных схем движения судов. Ключевые слова и словосочетания: безопасность судоходства, управление движением судов, система установления путей движения, интенсивное движение, опасное сближение, моделирование судопотока, алгоритмы на графах.

Authors: Gajaria Amy , Haynes Kevin , Kosic Yolanda , Alexander Donna
Published: October 2021

Black youth experience disproportionately poor health outcomes throughout Ontario's healthcare system, including the mental health and addictions system. The Substance Abuse Program for African Canadian and Caribbean Youth (SAPACCY) at the Centre for Addiction and Mental Health (CAMH) seeks to address this disparity by providing clinical services to youth who identify as Black and/or as having African and/or Caribbean heritage, and their families, who are struggling with problematic substance use and/or mental health concerns. The clinical team works from an Afrocentric, culturally responsive lens to promote recovery and support Black youth in working through their mental health and addiction concerns. The program offers mental health and addictions counselling and psychotherapy, psychiatric consultation, psychoeducation, resource navigation, advocacy, and case management services to assist youth and their families/caregivers in reducing harm, moving toward recovery, and making healthy choices for themselves and their family. This paper will discuss SAPACCY’s approach to helping clients build resilience and resistance to anti-Black racism.

After almost 50 years of data analysis, screening for colorectal cancer has proven to be an effective tool in reducing colorectal cancer mortality. However, implementing the optimal strategy represents a challenge for many healthcare facilities around the world. There is much discussion regarding how screening should be done, the optimal tools that should be used, and the proper timing for screening procedures. Another essential step is to maintain the adherence of patients to screening programs. Also, the recommendation for lowering the age to initiate screening is in progress, as there is an increase in colorectal incidence in people born after 1970.

How to Do Surgery on the Constitutional Law of Libel
Authors: Wright R. George
Published: October 2021

Of late, the constitutional law of libel has become the focus of increasing dissatisfaction. This dissatisfaction has taken various forms. The argument below, however, is that the most crucial defect of constitutional libel law lies in the Court’s continuing attempts to draw and utilize distinctions among public figure and private figure libel plaintiffs. The Court should abandon these attempts. Instead, the Court should attend, broadly and fundamentally, to the constitutionally vital distinction between libelous speech that does or does not address some matter of public interest and concern.
The argument below first emphasizes the constitutional logic underlying the Court’s initial imposition of First Amendment limitations on the state tort law of libel. The argument then critiques the Court’s initial embrace of a supposedly fundamental but actually distracting distinction between public and private figure libel plaintiffs. Interestingly, for a brief time, a divided Court returned to a focus on the underlying logic of putting First Amendment limits on the tort of libel, only to then re-distract itself with a renewed focus on questions of public and private figure status. Perhaps inevitably though, the Court’s emphasis on public versus private figure status has been qualified, in limited ways, by recourse to the genuinely basic and more valuable distinction between speech that does or does not address some matter of public interest and concern.
The argument then catalogs some additional problems inherent in the Court’s public versus private figure libel plaintiff distinction. The argument then defends the essential priority of a focus on the public interest versus merely private interest nature of the subject matter of the libel defendant’s speech. A brief, but comprehensive, conclusion then follows.

This paper present an assessment of the energy efficiency of various combinations of piston stages of an internal combustion engine, a compressor, and a Rankine engine as part of piston motor-compressor units based on modernized marine diesel engines. An eight-cylinder single-row diesel engine 8Ch23/30-1 is chosen as the object of research, the base of which is used as a single platform for creating powertechnology units for various purposes and power. The proposed variants for converting the original engine allow, with minimal costs for the development of design and manufacturing technology, to create gas engine compressor units with reduced fuel consumption and improved weight and size characteristics in comparison with the known mobile compressor stations driven by diesel internal combustion engines. In the paper, on the basis of the developed mathematical models of working processes, the possibility of joint operation of diesel cylinders with piston expanders of the Rankine cycle and one or more stages of a piston compressor is assessed. Various possible combinations of diesel cylinders, compressor cylinders and expander cylinders are considered, as well as the dependences of engine power and compressor performance depending on the number of compressor stages and the number of diesel power cylinders used.

Published: October 2021

The paper presents the influence analysis of such uncertainty factors as the heat transfer coefficient calculation method and the working chamber wall temperature on the mathematical modeling of the ammonia compression in a reciprocating compressor stage during the condensation of ammonia vapors. The mathematical model is based on the equation of the first law of thermodynamics for bodies with variable mass, the equation of state for real gases, the Clausius–Clapeyron and Newton–Richman equations. When determining the heat transfer coefficient value, several well-known dependencies for calculating these coefficients for dropwise and filmwise condensation have been considered. The calculation data shows that the instantaneous values of the ammonia pressure and temperature, as well as of the dryness fraction during compression in the wet steam region, significantly depends on the chosen method for calculating the heat transfer coefficient. Moreover, the walls temperature value of the compressor working chamber, where the compression occurs, has a considerable impact on the process under discussion. They are the determining factors and require special attention when the ammonia compression process is mathematically modelled in a reciprocating compressor stage, taking into account its vapors condensation.

The interstage channel is one of the factors affecting the efficiency of the molecular drag stage in a hybrid turbomolecular pump (TMP). The influence of parameters of the channel on the pumping performance of the molecular drag stage is investigated. The offered approach allows calculating the pumping performance of a molecular drag stage taking into account the effect of the interstage connecting channel on the pumping process. The comparison of the pumping characteristics of a molecular drag stage obtained in calculation taking into account the effect of the channel and excluding it is given. This article assesses the efficiency of the molecular drag stage in a hybrid TMP depending on geometric and dynamic parameters of the channel. The outcomes and recommendations allow to expand the range of working pressures of a hybrid TMP exclusively by means of parameters of the connecting channel.
M. W. Tofique, A. Löf, C. Millward, Z. Günther. Testing and calculation of impact fatigue strength of Flap-X and SS 716 flapper valve steel grades / trans from Engl. M. A. Fedorova
Authors:   Omsk State Technical University, Fedorova M. A.
Published: October 2021

During the operation of reciprocating compressors, the flapper valve opens and closes under fluid pressure and flow. As it closes, it strikes against the valve seat, generating stresses and noise. This cycle of loading produces bending and impact fatigue stresses in the reed. This load pattern is repeated billions of times during the service life of a compressor and it defines the service life and reliability. The goal of this study was to calculate the impact fatigue strength of the Flap-X and the SS 716 grades and, to provide the compressor manufacturers with the information they can use to specify a steel grade to be used in their compressors, for reliable service. Impact fatigue tests were conducted on a custom-built impact fatigue test rig that used air pulses to produce movement of the reed valves manufactured by a major European compressor manufacturer Nidec Global appliance GmbH, at a frequency of 315 Hz and pulse width of 2,2 milliseconds. The testing was conducted according to the staircase test method detailed in the International Standard SS-ISO 12107:2012. The impact fatigue strength of the Flap-X and SS 716 steel valves was calculated in terms of the impact velocity according to the modified staircase test method in the standard. The test results and their statistical analysis showed that the impact fatigue strength of the Flap-X grade was higher compared to the SS 716 grade. The calculation and testing of the impact fatigue strength of the flapper valve steel grades could help the compressor designers to select the optimum material for their compressor designs, to provide reliable service. The higher impact fatigue strength of the Flap-X grade, lower failure rate and longer impact fatigue life will allow the compressor manufacturers to design thinner valves, as Flap-X can sustain higher impact fatigue stresses reliably for longer time and, at the same time help reduce noise, as thinner valves produce less noise for a given pressure and frequency.

Published: October 2021

In this paper, we examine how the Covid-19 pandemic affected the quality of teachers’ assessment and feedback in Finland’s foreign language classes during the remote teaching period in spring 2020. Multifaceted assessment and feedback practices are underscored in Finland’s core curricula, forming a focal aspect of learning. Therefore, we studied teachers’ perceptions of their assessment and feedback practices at different school levels during the remote teaching period and how they considered the remote teaching period in students’ final assessment at the end of basic education. Data were collected through an online questionnaire and analysed using both quantitative and qualitative methods. Most of the 176 respondents felt that assessment and feedback practices were implemented successfully, and the final assessment was realistic and reliable. However, teachers’ perceptions were mixed on several issues, and differences were found in the amount and form of feedback between respondents and school levels or what competence demonstration or assignments to count towards the final assessment. In addition, the remote teaching period usually had less influence on students’ final grades than the last few months of basic education. The results suggest that more attention should be paid to enhancing feedback practices and connecting with students during remote teaching periods.

Published: October 2021

The main objective of the present research was to explore students’ experiences of emergency remote teaching during the Covid-19 pandemic. Specifically, we were interested in how strategies for coping with an emergency situation, learning strategies and positivity relate to this experience. A total of 337 university students participated in the study. The data were collected with an online questionnaire. The results show that students used more adaptive coping strategies (positive reappraisal, acceptance and refocus on planning) and fewer maladaptive strategies (blaming others, catastrophising). Furthermore, students reported the frequent use of two self-regulated learning strategies, i.e., environment structuring and goal setting, and the less frequent use of task strategies. Self-regulation and positivity explained a total of 40% of the variance of the students’ experience during the pandemic. Important predictors for more constructive experience were the frequent use of goal setting and environment structuring strategies, more pronounced positivity, and less frequent use of the catastrophising coping strategy. The research findings contribute to a better understanding of students’ emergency remote teaching and learning experience during the pandemic and its correlates. Moreover, the findings could enable academic staff to focus on the essential elements when supporting students to cope with the pandemic.
The importance of wild bee communities as urban pollinators and the influence of honeybee hive density
Authors: Weissmann Julie Anne , Walldorf Iris Rebecca Magdalena , Schaefer Hanno
Published: October 2021

While urban beekeeping is on the rise, data on the role of wild bee communities as crop pollinators in cities is still scarce. We analysed wild bee visitation rates on apple, plum, cherry, pear, blackberry, raspberry, and strawberry in a Bavarian city with a very high honeybee density of c. 19 hives/km2. During 137.5 hours of observation time, we observed 52 wild bee species on the studied crop plants. During more than 50 h of observation time on fruit trees in flower, we found that wild bees provided 41% of the total bee visits, honeybees the remaining 59%. Honeybee hive density had a significantly negative effect on wild bee abundance. Bumblebees appeared more tolerant to poor weather conditions than all other bee groups. Wild bee species richness on apple flowers was not significantly impacted by flower diversity in the surroundings of the trees. Together, our results suggest that species-rich wild bee communities in urban areas are important for pollination success in common fruit crops, especially under unstable spring weather conditions. Bee-friendly management of urban spaces should be prioritised to support wild bee communities as well as the increasing number of honeybees in cities.

Published: October 2021

In the era of data-driven policies, there is a need to ensure that decision-makers and citizens alike have easy access to the highest quality data. In the creation of RAD-on: an information system comprising reports, analyses, and data on science and higher education in Poland, we have attempted to overcome barriers to decision-making in the field of research and innovation. The system presents open government data (OGD) on subjects that are relevant to science and innovation policy, including: the publication patterns of scientists and academics in Poland; graduates from Polish universities and their incomes; and data on research projects conducted in Poland and financed using national and international funds. RAD-on aims to ensure transparency and participation through interaction with its users and a methodologically coherent approach to data. In this article, we describe the complex architecture of the RAD-on system, and present its reporting capabilities. While doing so, we focus on the development process, which accounted for recent studies on the usability of open data.

Mergers in university IT are a major challenge, as ongoing operations should be affected as little as possible. At the same time, it is not uncommon for different work cultures to collide between data centres, decentralized IT and administrative IT. There are also different expectations on the part of the user groups that need to be met. The merger of the Zentrum für Informationsverarbeitung (the IT centre with approx. 100 employees whose focus is on infrastructure) and the Stabsstelle IT und Prozessentwicklung (the administrative IT department with approx. 60 employees whose focus is on operations and organisation projects) to form the “WWU IT”, which took place at Münster University (WWU) at the beginning of 2020, can serve as a good example for similar IT restructuring at universities.

Authors: Lukina Marina Sergeevna , Gaynutdinova Dina Zyavdatovna
Published: October 2021

The article is devoted to investigation of functional status and structural characteristics of lexical innovations in socio-political discourse of the French language. The research material constitutes explanatory dictionaries of French such as Le Petit Larousse, Le Petit Robert and online versions of periodicals (daily newspapers Le Monde, Le Figaro, weekly magazine Le Nouvel Observateur). Urgency of the research calls forth necessity of accurate definition of the notion “neologism” and as a consequence theoretical grounds of mechanisms of vocabulary neologization on the basis of picked out criteria for its description. The aim of the research is study of mechanisms of activization and functioning of neologisms in socio-political discourse of the French language. It is shown in the article that in spite of active dynamics of vocabulary of modern politics lexicographical fixation of neologisms is distinguished by sufficient caution by virtue of objective reasons. Particular attention is given to analysis of content plane of lexical units taken from explanatory dictionaries of French. The most productive ways of formation of lexical neologisms in socio-political sphere of French is reviewed. The novelty of the study is in the involvement of media texts analysis data to discover the main vectors of the modern French language vocabulary development.

Introduction:
Very often, partial tear tendons of the superficial shoulder muscle are combined with arthrosis of the clavicular-acromial joint. This is due to violations of the shoulder-patch rhythm, which in turn leads to a chronic overload of the clavicular-acromial joint and the progression of arthrosis in this joint.

Aim:
The purpose of the study is to improve the results of treatment of patients with injuries of the supraspinatus tendon against the background of deforming arthrosis of the clavicular-acromial joint.

Material and methods:
For the study a clinical group was assembled, which consisted of 84 patients with injuries of the tendon of the supraspinatus and deforming arthrosis of the clavicular-acromial joint 3–4 parts. All patients, depending on the treatment, were divided into two groups.

Results and discussion:
The consequences and influence of the arthrosis of the clavicular-acromial joint were determined. Movements of the joint were examined. The shoulder joint function was under control in the post-surgery period, which provided particular results and conclusions according to the comparative analysis of the two groups.

Conclusions:
Based on the provided results, it can be concluded that deforming arthrosis of the clavicular acromial joint can cause contracture in the shoulder joint in patients after the suture of the tendon of the abdominal muscle.
HUBUNGAN KONSUMSI MINUMAN RINGAN DENGAN pH SALIVA PADA MAHASISWA PROGRAM STUDI KEDOKTERAN FAKULTAS KEDOKTERAN UNIVERSITAS MALIKUSSALEH TAHUN 2019
Authors: Maulina Nora , Sawitri Harvina , Millizia Anna
Published: October 2021

Hasil Riset Kesehatan Dasar Nasional (Riskesdas) tahun 2017 menyebutkan bahwa 23,4% penduduk Indonesia Mempunyai maslah kesehatan gigi mulut dan hanya 29,6% penduduk diantaranya yang menerima perawatan dan pengobatan dari tenaga kesehatan gigi. Hal ini mengindikasikan bahwa masih terdapat masyarakat yang belum menyadari pentingnya pemeliharaan kesehatan gigi dan mulut. Derajat keasaman (pH) saliva merupakan faktor penting yang berperan dalam rongga mulut, agar saliva dapat berfungsi dengan baik maka susunan serta sifat dari saliva harus tetap terjaga dalam keseimbangan yang optimal, khususnya derajat keasaman. Salah satu penyebab ketidakseimbangn saliva adalah pemilihan minuman ringan bersoda. Penurunan pH saliva dapat menyebabkan demineralisasi elemen-elemen gigi dengan cepat, sedangkam keneikan pH dapat membentuk kolonisasi bakteri yang menyimpan juga meningkatkan kalkulus.
DERAJAT pH SALIVA PADA MAHASISWA PROGRAM STUDI KEDOKTERAN FAKULTAS KEDOKTERAN UNIVERSITAS MALIKUSSALEH YANG MENGKONSUMSI KOPI TAHUN 2020

Kopi merupakan salah satu minuman yang tidak asing bagi masyarakat Indonesia dan memiliki aroma yang khas yang tidak dimiliki oleh bahan minuman lainnya. Minum kopi saat ini sudah menjadi bagian penting dari gaya hidup sebagian besar orang, karena kopi dianggap mampu mengurangi depresi akibat dari banyaknya dan padatnya aktivitas masyarakat sehari-hari, termasuk mahasiswa. Kebiasaan minum kopi dapat menyebabkan perubahan pH saliva karena kandungan sukrosa pada kopi, yaitu dimana sintesa ekstra sel sukrosa lebih cepat daripada gula lainnya, sehingga lebih cepat diubah menjadi asam oleh mikroorganisme di dalam rongga mulut. Penurunan pH saliva dapat menyebabkan  demineralisasi  elemen-elemen  gigi  dengan cepat, sedangkan kenaikan pH dapat membentuk kolonisasi bakteri yang menyimpan juga meningkatnya pembentukan kalkulus. Saliva dengan pH  kritis yaitu 5,5 dapat mengakibatkan disolushidroksiapatit yang disebut demineralisasi pada gigi. Oleh karena itu penelitian ini dilakukan pada mahasiswa Pendidikan Kedokteran Universitas Malikussaleh untuk mengetahui derajat pH saliva pada mahasiswa yang mengkonsumsi kopi. Populasi pada penelitian ini adalah seluruh mahasiswa Program Studi pendidikan Dokter Fakultas Kedokteran Universitas Malikussaleh angkatan 2016-2018 dengan jumlah sampel 60. Penelitian ini adalah penelitian observasional dengan menggunakan disain cross sectional, yaitu studi epidemiologi yang mempelajari prevalensi, distribusi, maupun hubungan penyakit dan paparan dengan mengamati status paparan, penyakit atau outcome lain secara serentak pada individu- individu dari suatu populasi pada suatu saat

Maerua angolensis DC. is collected from the wild for its edible leaves and fruits, and is also used as a traditional medicine. This study is aimed at evaluating the ethnomedicinal uses, phytochemistry and pharmacological properties of M. angolensis. Results of the current study are based on data derived from several online databases such as Scopus, Google Scholar, PubMed and Science Direct, and pre-electronic sources such as scientific publications, books, dissertations, book chapters and journal articles. The articles published between 1960 and 2020 were used in this study. This study revealed that the aerial parts, bark, leaves, roots and stem bark infusion and/or decoction of M. angolensis are mainly used as a protective charm and ethnoveterinary medicine, and a traditional medicine for pain, cancer, fever, malaria, sores, wounds and gastro-intestinal problems. Phytochemical compounds identified from the species include alkaloids, amino acids, anthraquinones, betaines, cardiac glycosides, cyanidin, esters, fatty acids, flavonoids, glucosinolates, phenols, saponins, sterols, steroids, tannins and triperpenoids. Ethnopharmacological research revealed that M. angolensis extracts have acaricidal, anthelmintic, antibacterial, antifungal, antidiarrhoeal, anticonvulsant, anti-diabetic, antidepressant, anti-inflammatory, antioxidant, antinociceptive, anxiolytic, anti-urolithiatic, antiprotozoal, molluscicidal and nematicidal activities. There is need for extensive toxicological evaluations of crude extracts and compounds isolated from the species since M. angolensis contains potentially toxic compounds
