Published: March 2023

Mental disorder is one of the most serious problems in today's time. Mental disorders can be classified into different sub-disorders according to changes in human behavior and mental condition. According to reports one out of seven people suffered from mental disorders. In this research paper, our main emphasis is to build an expert system that diagnoses people based on their symptoms, so people can diagnose themselves early before going to the doctor. Expert Systems are one of the most important applications in artificial intelligence that solves complex problems without human help. We provide different rules, facts, and relationships among different symptoms in our knowledge base, from which users can query their problems and get their results. We used SWI-prolog to build an expert system. There are a few types of disorders, such as mental disorders, neurodevelopmental disorders, eating disorders, etc.

The expert system solves problems within a specific area of the knowledge base. Prolog is a logical programming language which works on its knowledge base and effectively can be used to develop an expert system. Covid 19 is a pandemic deices and an expert system can be developed to diagnose this disease with the help of its symptoms that can be used as a knowledge base in Prolog. This expert system can make a fast diagnosis process for the covid 19 which is important to prevent the spread of the virus. Here we developed an expert system using prolog for diagnosis purposes. Like humans, these systems can get better with time as they gain more experience. Expert systems combine their experiences and expertise into a knowledge base that is then used by an inference or rules engine, a set of rules that the software employs, to apply to certain scenarios. Prolog is ideal for use with intelligent systems for a few reasons. Prolog can be viewed as a straightforward theorem prover or inference engine that derives from predefined rules. With the help of Prolog's built-in search and backtracking techniques, simple expert systems can be created.

Authors: Maulana Fajar , Asih Tri Sri Noor
Published: March 2023

The increasingly massive rate of information dissemination in cyberspace has had several negative impacts, one of which is the increased vulnerability to the spread of hoaxes. Hoax has seven classifications. Classification problems such as hoax classification can be automated using the application of the Deep Learning model. Bidirectional Temporal Convolutional Network (Bi-TCN) is a type of Deep Learning architectural model that is very suitable for text classification cases. Because the architecture uses dilation factors in its feature extraction so it can generate exceptionally large receptive fields and is supported by Bidirectional aggregation to ensure that the model can learn long-term dependencies without storing duplicate context information. The purpose of this study is to evaluate the performance of Bi-TCN architecture combined with pre-trained FastText embedding model for hoax classification in Indonesian and implement the resulting model on website. Based on the research that has been done, the model with Bi-TCN architecture has satisfactory performance with an accuracy score of 92.98% and a loss value that can be reduced to 0.191. Out of a total of 13,673 data tested with this model, only 414 data or in other words around 3% of the total data were incorrect predictions.

Published: March 2023

Background: Moringa oleifera seed, which is widely utilized as an affordable source of domestic water treatment, is also reputable for its various pharmacological applications globally. Aim: This study evaluates the toxicity and pharmacological potentials of Moringa oleifera seed protein while establishing the chemical profile. Method: Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and liquid chromatography coupled with electrospray ionization mass spectrometry (LC-ESI-MS/MS) were used to analyze the protein/peptide content of the purified protein. The protein was also investigated for in vitro anti-cancer potential on Hela and MDA-MB-231 cell lines, cytotoxic on 3T3 cell line, and toxicity to brine shrimps. In addition, the antimicrobial action of the protein (polypeptide) was evaluated. Results and Discussion: The MALDI-MS revealed three protein moieties with values of 3.4, 4.6, and 6.9 kDa. On the other hand, LC-ESI-MS/MS analysis revealed dipeptides and tripeptides, which include serinylarginine, leucylproline, leucyl-methionyl-glycine, isoleucyl-glycyl-methinine, glycyl-arginyl-aspartic acid, isoleucyl-glutamyl-methionine, di-phenylalanine, asparaginyl-aspartyl-histidine, seryl-tyrosyl-tyrosine, phenylalanyl-asparaginyl-tyrosine, and propanolyl-trytophanyl-glycine. The seed protein exhibited extremely low toxicity on both 3T3 and MDA-MB-231 breast cancer cell lines, while the standards, doxorubicin, and cycloheximide had IC50 = 0.5 ± 0.07 and 0.8 ± 0.10 μg/mL, respectively. Further, the protein showed no antibacterial or antifungal activity against all tested organisms. The protein also exhibited no lethality against brine shrimp. The in-silico toxicity results indicated that the peptides are not immunotoxic, carcinogenic, or mutagenic as most belonged to the tox class V except serylarginine predicted for tox class IV (harmful if swallowed). Hence, the intake of the protein remnant in water could be within the tolerable limit. Conclusion: The results obtained suggested that the protein content of the Moringa oleifera seed is non-cytotoxic. The result further validates the safety potential of the defatted and debittered seed material used as potential food sources for both humans and animals.

Women, who had an important power and respected status in state administration in pre-Islamic Turkish states, were later excluded from social life in Ottoman society. Especially after the Tanzimat Edict, the daughters of elite families began to take a prominent role in the defense of women's rights. Women's associations and feminist newspapers established in the Ottoman Empire, brought the women's movement and women's demands to the agenda of social life. After the establishment of the Republic of Turkey significant efforts were made to ensure that women could receive the same education as men and participate in the social life on an equal basis with men. With the adoption of the Turkish Civil Code in 1926, significant progress was made in terms of equality between women and men in the family and social life. In 1934, Turkish women became legally equal to men in politics, even before many European countries.

Published: March 2023

Airway management in laryngeal surgeries is a challenge for an anesthesiologist due to sharing of airway with a surgeon. The airway is often compromised with potential for perioperative worsening. Introduction of high-frequency jet ventilation (HFJV) in 1970 offered a new modality to secure airway in the laryngology procedures, excluding the disadvantages of classic tracheal intubation. HFJV is characterized by delivery of small tidal volumes (1–2 ml/kg) from a high-pressure jet at supraphysiological frequencies (1–10 Hz) followed by passive expiration. At ENT clinic of “T.Moșneaga” hospital HFJV are used for several years. Applied via supraglottic aproach, HFJV is first choice in patients with severe laryngeal obstruction, lesions of posterior glottic regions, a lot of pacients being suffering of laryngeal papillomatosis. This method can be safely used in microlaryngeal surgery, excluding a lot of serious intraoperative complications, esspecially combustions of conventional endotracheal tubes. Till now, there are not reported complications in our local practice of HFJV.

Published: March 2023

Liver transplantation is an important treatment for acute liver failure and end-stage liver disease. In 2002, the model for end-stage liver disease (MELD) was incorporated to prioritize patients awaiting liver transplantation. While there are data on how the MELD score affects wait time, there is a dearth of literature regarding other components. We aimed to evaluate the factors affecting the waiting time for TH. Using the database from the Republic of Moldova, patients aged 18- 65 listed for liver transplants in the period 2013-2022 were included. Variables tested in the model included patient characteristics, biochemical analyses, MELD score, and ABO blood group. The MELD score is used in prioritizing liver allocation and was expected to predict time on the waiting list. Mechanical ventilation and other markers of disease severity are associated with higher MELD scores, thus shorter waiting time. Further research is needed to address the reasons for ariation in waiting time in an attempt to reduce time to TH, standardize the listing process and improve patient outcomes.Objectives. The aim of the scientific paper was to analyze the risk factors and waiting time of patients with liver diseases on the waiting list for liver transplantation. Materials and methods. A retrospective 2013-2018 and prospective 2018-2022 study was conducted, in which 265 patients with decompensated liver cirrhosis, on the waiting list for liver transplantation, were included. The following databases were also used as a source of scientific literature: Google Scholar, PubMed and eLibrary. The keywords that were used in the search: „liver transplant”, „acute and chronic liver failure”. Results. Our results show that those with lower serum sodium had a shorter waiting time compared to candidates with higher sodium. Thus, patients with blood group A were the most patients, which is also a prognosis for this group to be more exposed to the risk of viral infection.

Published: March 2023

Tuberculosis, one of the ancient infections that especially affects humans, the main target organ of this disease being the lung, is caused by M. tuberculosis and remains one of the most important public health problems, especially in developing countries. The emergence of multidrug-resistant and extensively drug-resistant tuberculosis is considered a serious threat to tuberculosis control worldwide. The burden of drug-resistant tuberculosis remains increasing in countries endemic for this infection. The risk factors that influence this situation and that are elucidated more frequently in the specialized literature are the abusive use of drugs, the failure of the therapeutic regimen, the relapse of tuberculosis, the difficulty of obtaining drug sensitivity testing in a fast time. In Moldova, but also in other regions of Eastern Europe, drug resistance represents a serious obstacle in the effective control of this disease. There is evidence that the transmission of resistant strains, as opposed to the acquisition of resistance mutations through inadequate treatment of drug-susceptible tuberculosis, is the main driver of the high level of multidrug-resistant and extensively drug-resistant tuberculosis in these countries.

Teacher Strategies in Implementing English Medium Instruction
Authors: Richards Jack C.
Published: March 2023

The expanding role of English as the lingua franca of higher education worldwide has created a requirement for many university instructors to teach their subjects in English rather than in their usual language of instruction. Consequently, in many situations university teachers who were confident in their ability to provide quality teaching in their first language find themselves having to rethink their teaching approaches in order to teach their courses in English In implementing EMI, a common assumption has been that the primary issue affecting successful EMI is the English proficiency level of the EMI instructor. In this presentation the role that English plays in developing disciplinary literacy and competence is explored. A review of EMI teachers’ accounts of their instructional practices is used to to demonstrate the challenges content teachers face in teaching their academic subjects in English and ways in which they adapt their teaching in order to prepare for and manage EMI instruction.

A total of 334 (Female n = 190, Male n = 144) students selected from the 9th, 10th, 11th and 12th grades from these schools by random sampling method participated in the study. While the International Physical Activity Evaluation Questionnaire was used to determine the physical activity levels of the students, the academic achievement scores of the students were obtained from the e-school system of the Ministry of National Education. Descriptive statistics of the data obtained from the research were used to determine correlations between variables, Manova and Anova to determine whether there was a difference between variables, Post-Hoc Tests and Independent Sample “t” tests were used to determine the source of the differences between the variables. The significance level (p < 0.05) was taken. There was a negative correlation (p < 0.05) between students’ academic achievement levels and physical activity levels. While there were significant differences in academic achievement according to gender and grade level, significant differences were found in physical activity only in terms of gender (p < 0.05). As a result, it was determined that academic achievement was negatively affected by physical activity, female students and 12th grade students had better academic success, while male students were more active. Considering the health benefits of physical activity as well as the importance of academic success for students to settle in a university, these two concepts should be considered together, and new plans should be developed.

This study assessed the value of upgrading the quality of crop residues. The study involved improvement of quality of maize stover with urea, groundnut powder, soybean powder, mineralized groundnut solution and mineralized soybean solution. The nutritional value of the ground groundnut, ground soybean, mineralized groundnut solution, mineralized soybean solution, and the feeds improved with the ground legume stover and the solutions were assessed for nutritive value using laboratory proximate chemical analysis procedures. The stover were chopped before being mixed with urea, ground stover or the solutions and then offered to animals. Effect of upgrading maize stover with selected legumes was studied for nutritive value by proximate analysis. Five(5) samples of each feeding material were subjected to proximate analysis to determine their nutritive value in terms of crude protein (CP), gross energy (GE), dry matter (DM), ether extract (EE) and nitrogen free extractives (NFE), crude fibre(CF) using the AOAC methods of 2016. Samples were also evaluated for neutral detergent fibre (NDF), acid detergent fibre (ADF), using the Van Soest and Moore Method of 1991 calcium (Ca) using the Atomic Absorption Spectrophotometer (AAS-2016) and direct determination of phosphorus by Atomic Absorption Flame Spectrometry (AAFS-2017).

Обсуждена возможность применения методов машинного обучения в процессе про¬ек¬тирования электромагнитных устройств. В качестве примера рассмотрен элек¬тро¬¬магнит с прямоходным якорем.
Представлен процесс проектирования электромагнитного устройства класси-чес¬кими методами, проанализированы особенности определения значений конструк¬цион¬ных размеров и параметров электромагнита, вкратце изложен ход проектиро¬ва¬ния с рассмотрением основных его этапов. Показано, что в процессе проектирования при выборе значений параметров электромагнита (например, значения магнитной ин¬дук¬¬ции в воздушном зазоре) и значений коэффициентов для определения конструк¬цион¬ных размеров устройства имеют место некоторые неопределенности, связанные с тем обстоятельством, что в технической литературе для всех этих параметров и раз¬ме¬ров предлагаются не конкретные значения, а диапазоны значений, из которых сле¬дует сделать выбор. Ввиду имеющихся в процессе проектирования электромагнитного устройства указанных неопределенностей качество проектирования и, как следствие, качест¬во новой продукции во многом зависят от профессионального опыта проек¬тиров¬¬щика.
Применение методов машинного обучения в процессе проектирования электро¬маг¬¬нитных устройств будет способствовать нахождению соответствующих конечным целям проектирования значений параметров электро¬магнита, минуя классические ме¬то¬ды проектирования, а также исключению фактора опыта проекти¬ровщика в полу¬че¬нии окончательного результата проектирования.
В данной работе поставленная цель достигается изучением и реализацией на основе построенной базы данных таких эффективных методов машинного обучения, как дерево решений и линейная регрессия. При решении задачи классификации ме¬то¬дом дерева решений применен модуль DecisionTreeClassifier библиотеки scikit в среде Python с получением дерева глубиной 10 уровней. При решении задачи прогно¬зи¬рования методом линейной регрессии применен модуль LinearRegression. С целью реали¬зации данного модуля база данных разделена на две части: для обучения (80%) и для тестирования (20%).

Традиционно считается, что индуктивность индуктивной катушки без сер¬деч-ника определяется только способом намотки проводника и геометри¬чес¬ки¬ми параметрами. Проводники, выполненные из цветных металлов, являют¬ся нефер¬ро-маг¬не¬тиками с магнитной проницаемостью, примерно рав¬ной единице, независимо от вида материала проводника. В то же время магнит¬ная проницаемость сталей зна¬чи¬тель¬но выше. Это позволяет предполагать, что индуктивность индуктивной катушки без сердечника, намотанной стальным проводом, должна отличаться по величине энер¬гии, запасаемой катушкой при протекании по ней электрического тока.
В работе приведены результаты сравнительных испытаний, направлен¬ных на исследование влияния материала проводника, которым намотана катуш¬ка индуктивности без сердечника, на величину индуктивности. По ре¬зуль¬¬та¬¬там испытаний, проведенных методом вольтметра-амперметра, пока¬за¬но, что при намотке индуктивной катушкой без сердечника стальным прово¬дом стальная катушка может опосредованно выполнять функцию магнито¬про¬вода. При этом индуктивность катушки, намотанной стальным проводом, возрас¬тает до 20 раз по сравнению с катушками индуктивности аналогичных габаритных размеров, намотанными традиционно используемыми медными проводами. Также показано, что при намотке катушки без сердечника сталь¬ным проводом величина индуктивности зависит от величины тока, протекаю¬щего через индуктивную катушку. На примере индуктивной катушки без сердечника, выполненной стальным проводом, экспериментально опреде¬ле¬но, что изменение величины протекающего тока в 1,4 раза приводит к измене¬нию индуктивности в 1,5 раза, при этом ток, текущий через анало¬гич¬ную катушку, но намотанную медным проводом, не влияет на величину индуктивности в пределах инженерной погрешности до 10%. Сказанное позволяет пред¬по¬ла¬гать, что зависимость изменения величины индуктивности от протекаю¬ще¬го тока соответствует линейному участку основной кривой намагничивания мате¬¬риа¬ла проводников катушки. Это экспериментально указывает на возможность стальной катушки выполнять функцию магнитопровода в индук¬тивной катушке без сердечника.

Эффективность солнечных фотовольтаических модулей в значительной сте-пе¬ни зависит от загрязненности поверхности модулей. Если модули загрязнены, они соби¬рают меньше света, а значит, их эффективность снижается. Поэтому очистка по¬верх¬ности фотовольтаических модулей является необходимым и важнейшим про¬цес¬сом. В настоящей работе рассматриваются методы очистки фотовольтаических моду¬лей. Выделены две большие группы методов очистки: естественное очищение (в ре¬зуль¬¬тате осадков) и искусственное очищение (с помощью человека или разрабо¬тан¬ных чело¬веком средств). Искусственное очищение, в свою очередь, разделяется на не¬сколь¬ко методов: ручная очистка (сухая и влажная); установленная на грузовике систе¬ма очистки; полуав¬тома-тическая очистка, где чистящее устройство автомати¬чески перемещается над поверх¬ностью модулей; автоматическая (роботизированная) очистка.
Описывается робот для сухой очистки поверхности солнечных фотоволь¬таи-чес¬ких модулей, разработанный в научно-исследовательской лаборатории “Полупро¬вод¬никовые фотоэлектрические приборы” Национального политехнического универ¬си¬тета Армении. Разра¬ботанный робот механическим способом чистит поверхность сол¬неч¬ных фото¬вольтаических модулей с помощью круглой вращающейся щетки. Робот передвигается по поверхности солнечных фотовольтаических модулей, очищая их от пыли и других загряз¬нений. Он функционирует автоматически по заранее введенной периодичности очистки, а также может работать, фиксируя наличие пыли с помощью специально разра-ботанного в вышеуказанной лаборатории датчика пыли. Кроме этого, роботом можно управлять с помощью дистанционного пульта управления.
Экспериментальные исследования показали высокую эффективность функцио¬ни¬ро¬ва¬ния робота. Разработанный робот является экономически эффективным и может успешно применяться для очистки поверхности фотовольтаических модулей солнечных электростанций.

Инверторы фотоэлектрических (вольтаических) солнечных электростанций пре¬¬¬обра¬зуют нерегулярное напряжение постоянного тока солнечных панелей в стаби¬ли¬¬¬¬зи¬рованное по напряжению и частоте напряжение переменного тока. Вся выра¬бо¬тан¬¬¬¬ная солнечными панелями электроэнергия, преобразованная инвертором, пере¬да¬ётся в электрическую сеть. Форма переменного напряжения на выходе инвертора не¬¬си¬¬¬ну¬соидальная. Наиболее распространены инверторы напряжения. Выходное напря¬¬¬¬же¬ние инвер¬торов напряжения имеет прямоугольную форму, а инверторов то¬ка – экспоненциальную форму перезаряда конденсатора. Реальный уровень иска¬жения синусоидальности формы напряжения на выходе инверторов составляет по¬рядка нескольких десятков процентов. Высокочастотные гармоники в выходном напря¬же¬нии вызывают потери в электромагнитных устройствах и конденсаторах, высоко¬час¬тотные помехи по напряжению и полю, вибрации электрических машин и электромаг¬нитных устройств, отражаются на точности работы измерительных при¬бо¬ров и цифровых устройств, снижают коэффициент полезного действия (КПД) солнеч¬ной электростанции. Допустимый уровень искажения синусоидальности формы напря¬жения на входе потребителей установлен Государственным стандартом на уровне 8%. Требуемый уровень синусоидальности формы выходного напряжения обес¬пе¬чивается посредством фильтров или дополнительных устройств. Исследуются схема и режимы работы резонансного индуктивно-ёмкостного параллельно-последо¬ва¬тельного фильтра на выходе инвертора. Последовательное звено фильтра настроено на резонанс напряжений, параллельное – на резонанс токов при частоте 50 Гц. Учи¬ты¬вая принцип наложения, принимается, что ко входу фильтра приложены раздельно напря¬жение основной гармоники частотой 50 Гц и напряжение высших нечётных гармо¬ник. Определены выражения для выбора и расчёта параметров фильтра, вели¬чины искажения и КПД.

Произведен краткий анализ современного состояния энергетики. Рассмотрены перспективы развития мировой энергетики. Показана роль ее ядерной и возобнов¬ляе¬мой состав¬ляющих с точки зрения устойчивого развития, а также энергобезопасности и энерго¬обеспеченности отдельно взятого региона или государства. Приведены пока¬за¬тели энергообеспеченности Республики Армения и стран региона.
Анализ произведен на основе официально опубликованных данных таких между¬¬народных организаций, как Международное Энергетическое Агентство (МЭА), Между¬народное Агентство по Атомной Энергетике (МАГАТЭ), Организация Объеди¬нен¬ных Наций (ООН), Бритиш Петролеум и др.
Исходя из вышеизложенного, в статье рассмотрены концепция устой¬чивого раз¬ви¬¬тия, ее основные сферы и важность устойчивого развития низкоугле¬родной энер¬ге¬¬тики в этом контексте. Отмечено, что из представленных в документе Генеральной Ассамб¬леи ООН семнадцати целей устойчивого развития седьмой целью является обеспе¬чение всеобщего доступа к недорогим, надежным, устойчивым источникам энергии.
На основе анализа структуры производства и конечного мирового потребления электри¬чества как в целом мире, так и в отдельно взятых регионах и странах с учетом их ресурсообеспеченности рассмотрены прогнозы развития энергетики, в частности, ее ядерной и возобновляемой составляющих.
Частично затрагивается тема влияния пандемии COVID-19 на экономические пока¬затели и энергопотребление в мире.
С учетом перехода все большего количества стран на низкоуглеродную эконо¬ми¬ку, основанную на использовании низкоуглеродных источников энергии и имею¬щую мини¬мальный объем эмиссии парниковых газов в атмосферу, вкратце изложено, какие страны больше всего ''загрязняют'' атмосферу.
