FENOMENA PERLUASAN DAN PENYEMPITAN MAKNA DALAM ILMU SEMANTIK
Authors: Fatoni Ahmad Sirfi 
Published: February 2021

This article examines the expansion and narrowing of meaning in the field of semanticsThe reasons that triggers this research because the meaning in one period of time can change and most likely different at other times, this situation occurs because of the development of thinking of language users and cultural changes. From there emerged several phenomena such as the expansion and narrowing of meaning. This research is a qualitative research. As for the research method used descriptive analysis and critical. The findings of the research are: (1) The expansion of meaning is certainly closely related to language use. The language-speaking community in expanding the meaning contained in a word can use analogy or with self-help language itself. Expansion is often caused by social factors. A word that changes its usage from a limited circle into general usage sometimes will expand its meaning and lose some of its distinguishing elements, (2) The expansion of meaning is not only a booster in the development of semantics and method in the development of linguistic science, but on the other side it shows the weakness of a language, especially for common people, (3) The expansion of meaning is the result of the abortion of some the distinguishing features of a word, while the narrowing of meaning is the result of the addition of some the distinguishing features of a word, (4) Narrowing of meaning is found in the realm of scientific and artistic terms, in fact it’s closely related to the phenomena of homonym and polysemy.

Dakwah merupakan suatu usaha yang dilakukan dengan sengaja dan sadar dengan mengajak orang lain kejalan yang benar, yaitu berbuat baik dan mencegah perbuatan munkar. Tujuan dalam berdakwah merupakan tujuan tahap awal untuk menyalamatkan umat manusia dari lembah kegelapan dan membawanya ke tempat yang terang-benderang, dari jalan yang sesat kepada jalan yang lurus, dari lembah kemusyrikan dengan segala bentuk kesengsaraan menuju kepada tauhid yang menjanjikan kebahagiaan tidak terkecuali ditengan pandemi covid 19 yang terus mewabah hamper semua penjuru dunia.
Saat ini Pemanfaatan perkembangan teknologi informasi semakin nyata, tidak dapat dipungkiri bahwa teknologi dibutuhkan dalam kehidupan sehari-hari. Setiap kegiatan sosialisasi yang meliputi berbagai aspek kehidupan dipastikan memiliki peran media sosial di dalamnya. Sampai membuat pengaruh yang bersifat masif dalam kehidupan seseorang baik bagi masyarakat khususnya kalangan remaja, media sosial sudah menjadi candu yang membuat penggunanya tiada hari tanpa membuka media sosial. Lantas, Islam adalah agama yang “rahmatan lil alamin”. Sehingga Islam harus disebarluaskan kepada seluruh umat.

Published: February 2021

Science is learned by bringing real objects in daily life into the classroom. Therefore, the props are needed in learning science to make it easier for students to observe the concepts of science contained in an object. However, not all schools have good props to use in learning. This dedication to society aims to provide props that can be used as a medium of physics learning at SMA YPK Merauke. The props are accompanied by bilingual guides so that students can learn physics and English at the same time. The devotional activities were carried out through the introduction of props to physics teachers, demonstrations on how to use bilingual tools and guides, and mentoring. At the end of the activity, physics teachers were given a user response sheet to find out the teachers' perception of the props given. The results of the user response sheet show that the props can be appropriately used as a learning medium. Then, more props are needed to be given to schools in Merauke that do not have good props.
Abstrak
Sains dipelajari dengan membawa objek yang nyata di kehidupan sehari-hari ke dalam kelas. Oleh karena itu, alat peraga diperlukan dalam belajar sains untuk memudahkan siswa mengamati konsep-konsep sains yang terdapat pada suatu objek. Akan tetapi, tidak semua sekolah memiliki alat peraga yang memadai untuk digunakan dalam pembelajaran. Kegiatan pengabdian masyarakat ini bertujuan untuk menyediakan alat peraga yang dapat digunakan sebagai media pembelajaran fisika di SMA YPK Merauke. Alat peraga tersebut disertai dengan panduan bilingual agar siswa dapat belajar fisika dan Bahasa inggris secara bersamaan. Kegiatan pengabdian dilakukan melalui pengenalan alat peraga kepada guru fisika, demonstrasi cara penggunaan alat dan panduan bilingual, serta pendampingan. Di akhir kegiatan, guru-guru fisika diberikan lembar respon pengguna untuk mengetahui persepsi guru-guru terhadap alat peraga yang diberikan. Hasil lembar respon pengguna menunjukkan bahwa alat peraga dapat digunakan dengan baik sebagai media pembelajaran. Ke depannya, diperlukan lebih banyak alat peraga untuk diberikan kepada sekolah-sekolah di Merauke yang belum memiliki alat peraga yang memadai.

The impact of distrust of the judiciary on enforcement of court decisions in Ukraine
Authors: Vyshnevska Anastasiia 
Published: February 2021

The issue of enforcement of court decisions remains quite relevant today, despite the large number of studies conducted on thistopic.In Ukraine, the issue of reforming the system of enforcement of court decisions is quite acute.Non-execution of court decisions or its poor execution leads to the loss of the very meaning of justice, it undermines the credibilityof the judiciary in particular and the government in general.
Complaints about the activities of the judiciary exist both among citizens and among representatives of other branches of government,which has an extremely negative impact on the authority of the judiciary, the judiciary itself and the activities of the state as awhole. Ukraine’s judicial system is based on trust and respect for it, on confidence in its independence, impartiality and justice.The problem of non-enforcement of court decisions in Ukraine sharply undermines the authority of the state, because it is a signalof mass violations of human rights, but also causes significant distrust of Ukrainian society to the current government.Only through the full implementation of court decisions the fundamental principles of the world democratic system are realized:humanism, justice and the rule of law.An important way to increase trust and respect for the court is to form a legal culture and legal awareness of citizens, a greaterunderstanding of the importance of the court.It is also important to remember that people who provide court services are the face of justice. They have the greatest influenceon the formation of the authority of the judiciary, and consequently trust in it.It is necessary to introduce verification of candidates in local courts for compliance with the criteria of integrity and professional ethics.Among the most important tasks facing the judiciary in the state – is to gain the trust of citizens, strengthen their authority andincrease social status in society, which will significantly affect the quality of execution of court decisions.

Objective: To assess role of astaxanthin in downregulation of matrix metalloproteinases (MMP-1 and MMP-3) as potential mitigator for skin aging and antioxidant for different pathological diseasesStudy Design: Cross sectional.Place and Duration of Study: The study was carried out at Department of Biological Sciences of National University of Medical Sciences, Rawalpindi, Pakistan from June 2019 to March 2020.Materials and Methods: The docking studies of two different matrix metalloproteinases (MMP-1, MMP-3) with astaxanthin were carried out using Autodock/vina. The structural details were obtained from protein data bank and subjected to energy minimization using the UCSF Chimera 1.12.|Results: Out of the two selected targets, we found the highest binding energy (-11.9 kacl/mol) was for stromelysin-1 and astaxanthin docked complex. Astaxanthin was found to bind within the reported, predominantly hydrophobic S1, active site of protein mostly by hydrophobic interactions. The catalytic zinc ion has also shown to establish an electrostatic interaction with histidine residues of the MMPs.Conclusion: The current results suggest that astaxanthin has potential inhibitory activity on MMP-1 and MMP-3 and can be used as treatment to sunburns and skin aging.

При проверке остойчивости по основному критерию или критерию погоды, кренящий и восстанавливающий момент мо гут быть равны между собой. С одной стороны этого достаточно, что бы судно было признано остойчивым при действии динамического ветра, с другой стороны, минимальные отклонения различных элементов и характеристик судна от расчётных значений, могут вызвать рост кренящего и снижение восстанавливающего моментов, который при низком уровне самой остойчивости судна может привести к чрезвычайной ситуации, и в худшем случае потере судна. В настоящей работе представлен общий подход к определению фактически необходимого коэффициента запаса остойчивости, проанализированы факторы влияющие на изменение действующих на судно моментов при его наклонении на конечные углы. Авторами так же рассмотрены минимальные приращения данных факторов, которые допускаются действующими Правилами Российского Речного Регистра и фактически приводят, к незначительной ошибке. В качестве примера рассчитан фактический коэффициент запаса остойчивости, для сухогрузного судна смешанного (река-море) плавания.
When checking the stability of the main criterion or the weather criterion, the heeling and restoring moment can be equal to each other. On the one hand, this is sufficient for the ship to be considered stable under the influence of dynamic wind, on the other hand, the minimum deviations of various elements and characteristics of the vessel from the calculated values can cause an increase in the heeling and reducing the restoring moments, which, if the ship's stability is low, can lead to an emergency situation, and in the worst case, the loss of the vessel. This paper presents a General approach to determining the actual required coefficient of stability margin, and analyzes the factors that affect the change in the moments acting on the ship when it tilts to the final angles. The authors also consider the minimum increments of these factors, which are confirmed by the current Rules of the Russian River Register and actually lead to a minor error. As an example, the actual coefficient of responsiveness is calculated for a dry cargo ship of mixed (river-sea) navigation.

Оксиды азота являются наиболее опасными химическими соединениями, находящимися в составе отработавших газов судовых дизелей. Уменьшение содержания оксидов азота является весьма сложной задачей, так как это связано с ограничениями максимальной температуры цикла, термического КПД и, следовательно, с ограничениями по топливной экономичности. Одним из эффективных способов уменьшения концентрации оксидов азота является применение водотопливных эмульсий. Недостатком применения эмульсии является увеличение удельного расхода топлива. Целью работы является исследование возможности одновременного снижения уровня вредных выбросов и расхода топлива при работе дизеля на ВТЭ. В статье приведены описание экспериментальной установки и результаты экспериментальных исследований дизеля Ч10,5/12 на безводном топливе, грубой и микрогетерогенной водотопливных эмульсий с содержанием воды 15% при работе по винтовой характеристике. С использование полученных в ходе испытаний дизеля индикаторных диаграмм выполнен сравнительный анализ рабочего процесса на различных топливах. Полученные результаты выполненных исследований подтвердили эффективность использования микрогетерогенной эмульсии, в сравнении с грубой эмульсией для снижения выбросов оксидов азота с отработавшими газами в судовых дизельных энергетических установках и уменьшения удельного расхода топлива.
Nitrogen oxides are the most dangerous chemical compounds which come out with the exhaust gases of marine diesel engines. Reducing nitrogen oxides is challenging due to limitations on maximum cycle temperature, thermal efficiency, and hence fuel economy limitations. One of the effective ways to reduce the concentration of nitrogen oxides is the use of water-fuel emulsions. The disadvantage of using an emulsion is the significant fuel consumption increase.
This article describes the experimental setup and the results of experimental studies of a Ч10.5/12 diesel engine on anhydrous fuel, coarse and micro-heterogeneous water-fuel emulsions with a water content of 15% when operating in service. Performance diagrams obtained during the diesel engine tests let the authors get a comparative analysis of the working process using various fuels. The results confirmed the effectiveness of using a micro-heterogeneous emulsion, in comparison with a coarse emulsion, to reduce emissions of nitrogen oxides with exhaust gases in marine propulsion systems and to reduce fuel consumption.

Published: February 2021

Предложен метод расчёта расхода топлива судового дизеля на разных режимах, для которого достаточно знания всего одного параметра – эффективной мощности двигателя. Потребность в таком методе обусловлена необходимостью оценки эксплуатационных расходов на ранних стадиях проектирования, когда эксплуатационные параметры судна неизвестны. Существующие методы оценки расхода топлива, требующие минимального набора параметров, не позволяют адекватно учитывать изменяющиеся условия плавания, что характерно для работы речных судов. Приведён анализ некоторых таких методов. На основе аппроксимации индикаторного к.п.д. построен аналитический метод, вычисляющий расход топлива судового дизеля при заданной мощности и относительной частоте вращения. Приводятся примеры расчёта расхода топлива для реального судна и стендовой характеристики судового дизеля. Построенный метод позволяет дополнить существующие методы расчёта ходкости новых судов и адекватно прогнозировать расход топлива в условиях эксплуатации судов на внутренних водных путях.
A method for calculating the fuel consumption of marine diesel engines is proposed. It is enough for this to have only one parameter - the brake power. This method is necessary as there is the need to estimate operating costs in the early stages of ships design, when the ships parameters are unknown. Existing methods for estimating fuel consumption, requiring a minimum set of parameters, are not adequate for inland waterway conditions. An analysis of some of these methods is given. Based on approximation of indicator efficiency proposed analytical method for prediction of the fuel consumption of a marine diesel engine at a given power and relative speed is based on the analytical approximation of indicated thermal efficiency. Examples of predicting fuel consumption for the real ship and the marine diesel engines are given. The proposed method complements the existing methods for propulsion of new ships and to adequately predict of fuel consumption on inland waterways.

Объектом исследования является ледовая балка, двигающаяся с постоянной скоростью на наклонную опору. Цель исследования – расчетно-экспериментальное определение координаты разлома ледовой балки с учетом различных способов моделирования упругого основания и сопоставление с данными модельного эксперимента. Для моделирования взаимодействия ледовой балки с наклонной опорой используется метод конечных элементов. Материалом для разработки численной модели служат данные серии модельных экспериментов. Разработана модель с тремя различными способами моделирования упругого основания: по Винклеру, дискретно распределёнными упругими элементами и при помощи твёрдого тела. Подтверждена эквивалентность всех способов моделирования упругого основания. Рассмотрено два типа контакта между водным основанием и балкой. Определение координаты разлома балки из модельного льда при малых скоростях может быть выполнено в квазистатической постановке без решения динамической задачи. Предложено три способа моделирования упругого основания.
This paper discusses moving of an ice beam at constant speed onto an inclined support. The purpose of this study was experimental and numerical determination of the ice beam breaking distance, considering various methods of the elastic foundation modeling and comparison with the data of the model experiment. The finite element method is used to model the interaction of an ice beam with an inclined support. Numerical model was based on the data from the series of model experiments. The model with three different methods for modeling an elastic foundation has been developed: according to Winkler, discretely distributed elastic elements and using a rigid body. The equivalence of all the methods of elastic foundation modeling is confirmed. The influence of the type of contact between the water base and the beam on modeling accuracy is analyzed. Determination of the beam breaking distance for model ice beam at low speeds can be performed in a quasi-static formulation without solving the dynamic problem. Three methods are proposed for modeling an elastic foundation.

Resumen

La enfermedad de Castleman fue descrita por primera vez en 1956 y se trata de un grupo de desórdenes linfoproliferativos que comparten un patrón histológico.

La enfermedad se divide principalmente en unicéntrica o multicéntrica. La multicéntrica afecta a múltiples regiones ganglionares, está frecuentemente relacionada con el VHH-8 en pacientes inmunodeficientes, aunque puede ser idiopática. Estos pacientes generalmente presentan síntomas sistémicos.

La enfermedad de Castleman unicéntrica afecta a una única región ganglionar y generalmente es asintomática. Es más frecuente en pacientes jóvenes y de sexo femenino. En caso de presentar síntomas, suelen estar relacionados con el efecto masa que provocan los ganglios afectos. Si la enfermedad es resecable, la extirpación completa es curativa en la mayoría de los pacientes. En los casos irresecables, se pueden utilizar otras terapias, tanto sistémicas, basadas en inmunosupresores, como locales, destacando la embolización y la radioterapia.

Presentamos el caso de una paciente mujer de 24 años estudiada por dolor en miembro superior izquierdo. Las pruebas complementarias pusieron de manifiesto un conglomerado adenopático retropectoral sin afectación a otros niveles. El estudio anatomopatológico tras la resección quirúrgica mostró hallazgos compatibles con una enfermedad de Castleman.
