Reflections on the Lack of Consideration of Ethnic Ancestry to Stratify Clozapine Dosing
Authors: de Leon Jose
Published: March 2023

This review article argues against trusting standard clozapine references, including the US package insert, because they do not include advances in the sciences of pharmacokinetics and pharmacovigilance and ignore the effects of ethnic ancestry on therapeutic dosing. The minimum therapeutic dose leading to the minimum therapeutic concentration of 350 ng/mL in serum/plasma can be used to compare individuals/groups with treatment-resistant schizophrenia. The US clozapine package insert recommends targeting doses of 300–450 mg/day and, subsequently, increments of up to 100 mg with a maximum dose of 900 mg/day. Ethnic ancestry is defined by DNA ancestry group. Asians (people with ancestry ranging from Pakistan to Japan) and Indigenous Americans are similar in clozapine dosing; their average clozapine minimum therapeutic dose ranged from 166 mg/day (female non-smokers) to 270 mg/day (male smokers). For those with European ancestry, average clozapine minimum therapeutic doses ranged from 236 mg/day (female non-smokers) to 368 mg/day (male smokers). Based on limited studies, Black (African sub-Saharan ancestry) patients may be treated with typical US doses (300–600 mg/day), assuming no poor metabolism (PM) status. Ancestry’s impact on clozapine lethality in four countries is discussed (two countries with highly homogenous populations, Denmark and Japan, and two countries with increasingly heterogenous populations due to immigration, Australia and the UK). An international guideline with 104 authors from 50 countries/regions was recently published, providing 6 personalized clozapine titration schedules for adult inpatients (3 ancestry groups and PM/non-PM schedules) and recommending c-reactive protein monitoring at baseline and weekly for 4 weeks.

On account of ever increasing complexities and uncertainties, construction project management has become more and more challenging day by day. As a result, continuous project monitoring emerges as a prime concern for the planned activities to be completed on schedule and within budget. Limitations in traditional time and cost monitoring practices result in time and cost overrun which seriously hinder successful completion of a project. The impact of time and cost at various stages of a construction project is a critical factor in the project's successful completion and management. Most of the construction projects in Bangladesh have completed with extra time which leads the demand of additional cost because of poor project monitoring and controlling system. In these consequences, a widely recognized emerging project monitoring technique, Earned Value Management (EVM) can be introduced to conduct project progress, performance and forecasting. EVM measures the actual work completed on a project at any time with respect to the original cost and schedule by integrating project scope, cost and schedule in order to predict cost and completion timeline. In this study, a three-storied residential building project at Khulna, Bangladesh was considered to perform earned value management for tracking whether the project is either delay or not along with either over budget or under budget at any particular day. The construction operations up to the first six months were assessed using an EVM based on a work-breakdown structure (WBS), in which the real activities and costs were compared to the projected program. The progress of the under constructed project considering cost and schedule were also evaluated through analyzing EVM indexes using Microsoft Project Professional 2019 software. Construction performance was assessed respecting cost variance (CV), schedule variance (SV), cost performance index (CPI) and schedule performance index (SPI). CV and CPI are evidently less than 0 and 1, respectively, indicating thatthe project was on the verge of cost overrun; on the other hand, SV and SPI are both less than 0 and 1, indicating that the project was running behind budget after six months. As a result, if this project is pursued at its current pace, it will be finished behind schedule and above budget. It will undoubtedly assist project rescheduling to bring the performance back to harmony.
Journeys through the Past and to the Future: V. A. Obruchev and Popular Enlightenment in the Natural Sciences, 1886–1956
Authors: McDonald Garret J.
Published: March 2023

This essay examines the life and career of famed Russian geologist, geographer, and academician of the Soviet Academy of Sciences V. A. Obruchev. By emphasizing Obruchev’s commitment to popular enlightenment within and beyond his scientific disciplines, a clearer portrait of Obruchev’s lasting influence in Soviet science and literature emerges. Over the course of his career, Obruchev devised an original model of public science, one that renegotiated the traditional boundaries between science fiction, popular science, and academic discourse. As a result, Obruchev’s scientific research granted form and function to his popular fiction and his fiction, in turn, provided a space to explore the possibilities of scientific hypotheses and promote the active research of the scientific phenomena Obruchev considered significant. By the time of Obruchev’s death in 1956, other natural scientists, especially geoscientists, and science fiction authors had coopted Obruchev’s approach to popular enlightenment, cementing his legacy.

Published: March 2023

Beliefs have been identified as an affect on the psychology of mathematics education. Additionally, representations play a paramount role in mathematics teaching and learning. However, few studies have examined prospective teachers' beliefs and their relationship to representations in problem-solving. The purpose of this study is to examine prospective mathematics teachers' beliefs and representations in solving word problems review from gender differences. This study involves 103 college students from the mathematics education department at a public university in Merauke Regency. The data were gathered using a questionnaire, a test, and in-depth interviews. A questionnaire was utilized to elicit the belief of prospective teachers. A test and interview were conducted to evoke data about participants' representations when solving word problems. The male student was found to be capable of arriving at a solution employing multiple representations. Due to the inaccurate representation constructed, the female student was unable to find the correct solution. This work implies that lecturers should heed prospective teachers' beliefs and generate representations of the focal point of classroom learning practice.

Authors: Zurweni Zurweni , Malik Affan
Published: March 2023

The free learning-campus program (MB-KM) contained in SN-Dikti 2020, is very relevant to the demands of 21st century education in order to address the challenges of learning in the global era. The MB-KM program provides opportunities for students to master various fields of science, develop creativity, capacity and other competencies related to the needs of the world of work. The results of the needs analysis show that there are still four competencies that have not been maximally mastered by students, namely: school management competencies, analytical thinking, technological novelty and science behavior with an average of 51.75%, while the other three competencies: pedagogical competence, high school chemistry science, and DIGITAL LEARNING IT competence have been very good with an average of 80.20%. Against the background, this was conducted research on the Development of Rational-Creative Performance Technology Training Model for Chemistry Education Students. This research is educational development research (Borg & Gall: 2007). The characteristic of this training model is in the form of Merdeka Learning Teacher Mover for school education. The MODEL ID used to design this training model is adapting the modified ASSURE model, while the Rational-Creative Performance Technology Training Model was developed by Zurweni & Affan Malik (2020). The results showed that the Rational-Creative Performance Technology Training Model has four synths: Innovation Intervention Orientation, Rational Exploration, Rational Technology Training and Evaluation. Evaluation and validation results and trials state that the Rational-Creative Performance Technology Training Model falls into the category of good, with field trials have not been successfully implemented due to the covid-19 pandemic. It was concluded that this Rational-Creative Performance Technology Training Model is worth using and is a new breakthrough as an alternative to enrichment in the debriefing of students who follow the PLP Program to partner schools. It is recommended to use this training model at the level of the Study Program as well as at the student debriefing enrichment session before following the introduction of the school field.

Published: March 2023

The cognitive level between teachers and students is clearly different in problem-solving. In the mathematics context, especially the function problem was only in geometric expression form, for knowledge construction and student's learning should use their cognitive level capacity. Not only the solving process is based on that, but also learning should be efficient for all students, and analyzing those processes is the purpose of identification inefficient issues in this study. This investigative study was held on three respondents purposively selected from a science program of senior high school in West Jakarta, Indonesia. This study found that in the solving process, all students chose to construct an algebraic representation of the function by organizing concepts relevant to fragmented conceptualization. The process has held to apply each concept procedurally. There has been a resource and that is one concept of the domain of function, so the completion is an inefficient process because all three students were ignoring it to use. All three process for solving to the student’s academic culture, most common for emphasizing in learning related to the problem and their cognitive capacity.

Published: March 2023

This study aims to identify the profile of STREM-based science writing skills in pre-service science teachers. The study was done using a descriptive method through a study of STREM-based science teaching materials documentation written by the pre-service science teachers. The target population is the seventh-semester students. Fifty people who are enrolled in the elective course of Integrated Science Learning were selected through Purposive Sampling. Performance assessment of the STREM-based science teaching materials was done using an analytical rubric with a score of 1-4 on the aspect of pedagogic, content, and context. Determination of inter-rater reliability was taken from 25 random samples of teaching materials and correlated their scores using Pearson's correlation. The inter-rater reliability score obtained is 0.938 in all aspects of teaching materials; 0.690 in the pedagogic aspect; 0.976 in the aspect of content; and 0.921 in the context aspect. The score of the teaching materials is then converted in the form of a percentage and interpreted based on certain criteria. The average score of pre-service science teachers' writing skills was 53.3% in the "good" criteria. The writing quality of teaching materials has not yet met the expected criteria from the pedagogic, content, and context aspects. Thus, it is important to develop appropriate learning strategies to improve the writing skills of STREM-based science teaching materials for pre-service science teachers.

The Effect-Size Benchmark That Matters Most: Education Interventions Often Fail
Authors: Kraft Matthew A.
Published: March 2023

It is a healthy exercise to debate the merits of using effect-size benchmarks to interpret research findings. However, these debates obscure a more central insight that emerges from empirical distributions of effect-size estimates in the literature: Efforts to improve education often fail to move the needle. I find that 36% of effect sizes from randomized control trials of education interventions with standardized achievement outcomes are less than 0.05 SD. Publication bias surely masks many more failed efforts from our view. Recognizing the frequency of these failures should be at the core of any approach to interpreting the policy relevance of effect sizes. We can aim high without dismissing as trivial those effects sizes that represent more incremental improvement.

The article examines the literary heritage of the famous Balkarian writer, playwright Zhagafar Tokumayev. The main purpose of the work is to fully present the panorama of the creative work of the master of the artistic word, to determine its role in the evolution of national written literature. The article is preceded by a short autobiographical reference focusing on the influence of the writ-er's life experience on the formation and development of his artistic consciousness. Tokumayev's creativity is considered from the point of view of genre, thematic diversity, the ethnocultural specificity of his works is determined. Analysis of the author's aesthetic experience in small and medium epic forms (stories "Agronomist", "Mistake", "Courage", "Investigator's Story"; the sto-ries "The fate of the orphan", "Descendants of the sleds", "The Pass") it shows a wide thematic range (istroic, moral, social, household, detective) of works, reveals characteristic artistic features (the connection of times, the evolution of consciousness of the main actors at the sharp fractures of history and in extraordinary life circumstances). The article focuses on the trilogy of J. Toku-maeva's "Dagger of Revenge", recognized as the first experience of artistic cyclization in Balkar novelistics. The constructive role of Zh is also noted. Tokumaeva in the development of drama and stage art (comedies "Imaginary authority", "Shadows", "Jamilya", "Chonai marries", included in the "golden fund" of the repertoire of the Balkarian State Drama Theater named after K. Kuli-yev). The versatility of the writer's talent is evidenced by children's prose ("The Stories of Aldar-bek from Kurnayat"), humorous miniatures ("Mocker Chonai"). As a result of the study, the au-thor's desire throughout his creative life to expand genre-thematic horizons in understanding artis-tic reality, which subsequently contributed to the enrichment of the spiritual culture of the Balka-rian ethnic group.
Military, political, administrative and economic activities of general G.A. Emanuel in the Cauca-sus (1826–1831)
Authors:   Kabardian-Balkarian Scientific Center of the Russian Academy of Sciences, Asker Khashirov
Published: March 2023

The article handles the military-political and administrative-economic activity aspects of General G.A. Emanuel as commander of the troops on the Caucasian line, in the Black Sea and Astrakhan, head of the Caucasian region. His contribution to the settlement of interethnic relations in the Central Caucasus is indicated. G.A. Emanuel preferred to use diplomatic methods instead of mili-tary punitive methods, whereby several ethnic groups voluntarily became part of the Russian Em-pire. But, against the Circassians of the Western Caucasus on his instructions, military punitive expeditions were conducted. Activities of G.A. Emanuel had a significant impact on the situation of Central Caucasus peoples: he organized the bringing of some peoples into the citizenship of the Russian Empire and established their political and administrative integration into the Russian Empire. In the process of administrative practice, he organized and conducted the first military scientific expedition to Elbrus in 1829. It can be concluded that the actions of G.A. Emanuel were aimed at integrating the peoples of the Caucasus with the Russian Empire in more civilized ways than those who held this position before and after him.
Postnatal Gelişme Dönemlerinde Capsaicin Uygulanan Fare Testislerinde TGF Beta-1’in İmmunohistokimyasal Lokalizasyonu

Published: March 2023

Transforme edici büyüme faktörü beta-1 (TGF Beta-1) testiküler fonksiyonların parakrin ya da otokrin düzenleyicilerinden biridir. Bu çalışmada, postnatal gelişme sürecinde Capsaicin (CAP) uygulanan farelerin testislerinde TGF Beta-1’in lokalizasyonu incelendi. Çalışmada 60 adet Swiss albino soyu erkek fare kullanıldı. Deney grubundaki 21 günlük farelere(n:30)75 gün boyunca her gün deri altı yolla 1mg/kg dozunda CAP enjekte edildi. Deney ve kontrol gruplarından 10’ar hayvan, 35. günü (puberte dönemi), 50. günü (puberte sonrası dönem) ve 75. günü (erişkin dönem) temsil edecek şekilde gruplara ayrıldı. Örneklenen testislerin tartımı sonrası rutin histolojik prosedür uygulandı. Çalışma süresince her gün kontrol ve deney grubu hayvanların canlı ağırlıkları tartıldı. Tüm deney gruplarındaki hayvanların canlı ağırlık ortalamalarının kontrol gruplarına oranla daha fazla olduğu ve bu iki grup arasında p<0,05 düzeyinde istatistiki önem saptandı. 35 ve 50 günlük deney gruplarının testis ağırlıklarının kontrol gruplarına oranla daha fazla olduğu gözlendi. Gözlenen farklılıklar arasında istatistiki bir öneme rastlanmadı.TGF Beta-1 immunreaksiyonu kontrol ve deney gruplarında, farklı boyanma yoğunluklarında, Leydig hücrelerinde ve genç spermatidlerde gözlenirken Sertoli hücrelerinde, spermatogonyumlarda ve erişkin spermatidlerde immunreaksiyon gözlenmedi. Genç spermatidlerdeki boyanma yoğunluğu her iki grupta da hemen hemen benzerdi, fakat kontrol gruplarında boyanma yoğunluğu yaş ile artarken deney gruplarındaki bu artış 75 günlük grupta gözlenmedi. Leydig hücrelerindeki boyanma yoğunluğu ise deney gruplarında yaş ile artış gösterirken kontrol gruplarında farklı boyanma yoğunlukları saptandı. Sonuç olarak CAP’ın, spermatogenez sırasında Leydig hücrelerindeki reseptörüne bağlanarak TGF Beta-1 immunreaksiyonunu arttırdığı sonucuna varıldı.

Effective deterrence requires confidence in robust naval replenishment capabilities, in order to maintain extended physical presence and support sustained military operations. While many authors have focused on vulcanizing penetration, projection, and defensive capacity, a compelling synergy arises from synthetic fuel generation, which may be conducted near point-of-need. In this work, we consider a modeling and simulation-driven approach to estimating the logistical and operational impacts of marine and aviation fuel from alternative sources. Toward this end, we present the Fuel Replenishment and Logistics Simulation (FuelSim), a novel agent-based fuel paradigm assessment application designed to be lightweight, flexible, and integrable with large-scale systems analyses.

The Impact of Bionic Prostheses on Users’ Self-Perceptions: A Qualitative Study
Authors: Bretschneider Maximilian , Meyer Bertolt , Asbrock Frank
Published: March 2023

Bionic devices for reestablishing or augmenting users' capabilities (e.g., bionic prostheses or exoskeletons) are becoming increasingly common. While prior research examined how such devices affect others’ perceptions of their users, little is known about how these devices affect users’ self-image and -perception, and the corresponding theory is scarce. To account for this gap, we conducted semi-structured interviews with users of bionic prostheses to obtain insights into the users' self- and meta-perceptions. Results of our qualitative analysis indicate that using bionic prostheses influences the social (self-) perception of bionics users in multiple ways, such that users describe themselves as being seen as more competent by others and treated differently after receiving the bionic prosthesis in comparison to simpler models. Results imply a somewhat complex dual identity among users in the sense that the bionic device instills competence, but disability-related feelings of stigma are present simultaneously. Despite being exploratory, our findings thus indicate that using bionic devices affects users' self-perception, stereotypes, and interpersonal perceptions. The introduction of exoskeletons and similar technologies in future work contexts, for example, might thus have unintended social consequences that need to be accounted for.
Unlocking nonlinear dynamics and multistability from intensive longitudinal data: A novel method
Authors: Cui Jingmeng , Hasselman Fred , Lichtwarck-Aschoff Anna
Published: March 2023

The availability of smart devices has made it possible to collect intensive longitudinal data (ILD) from individuals, providing a unique opportunity to study the complex dynamics of psychological systems. Existing time-series methods often have limitations, such as assuming linear interactions or having restricted forms, leading to difficulties in capturing the complex nature of these systems. To address this issue, we introduce fitlandr, a method with implementation as an R package that integrates nonparametric estimation of the drift-diffusion function and stability landscape. The drift-diffusion function is estimated using the Multivariate Kernel Estimator (MVKE, Bandi & Moloche, 2018), and the stability landscape is estimated through Monte-Carlo estimation of the steady-state distribution (Cui et al., 2021, 2022). Using a simulated emotional system, we demonstrate that fitlandr can effectively recover bistable dynamics from data, even in the presence of moderate noise, and that it primarily relies on dynamic information from the system instead of distributional information. We then apply the method to two empirical single-participant ESM datasets and compared the results with the simulation datasets. Whereas both datasets show a bimodal distribution, fitlandr only revealed bistability in one of them, indicating that bimodality in ILD does not necessarily imply the existence of bistability in the underlying system. These results demonstrate the potential of fitlandr as a tool for uncovering the rich, nonlinear dynamics of psychological systems from ILD.

The dairy industry is not usually linked with simple environmental problems, its impression of the environment with different troubles. During the last decades, several types of treatment and procedures have been applied to relieve contaminants from dairy wastewater before being discharged into the environment. The procedure used in this work has green items and saves energy. This route is termed membrane distillation (MD). The method is defined as a contemporary method that can be summed up in financial expenses and electrical effort in addition to the guests and even preservation or care. Recompenses of this system could be summarized in economical, physical as well as Operation and Maintenance (O&M) attributes. Synthetic models of dairy wastewater have been prepared. Physiochemical analysis has been done to have the best decision on the implementation of treatment. American Public Health Association (APHA), American Water Works Association (AWWA), and Water Environment Federation (WEF) have been used as references for mad these tests. The results gathered to show the ability to remove lead at a rate of 98.89%. This figure could be prepared as a high value compared with other techniques' efficiency. The operation temperature to get the best treatment has been 15°C, which is very close to the normal medium. The best removal could be obtained at a temperature of 15°C. The fluctuation of temperature could be a role in rising or decreasing removal efficiency but to some extent.
REVIEW OF RECYCLING NATURAL AND INDUSTRIAL MATERIALS EMPLOYMENTS IN CONCRETE
Authors: Adil Rasool Dalia , Al-Moameri Harith , Abdulkarem Mais
Published: March 2023

Concrete is the most commonly used and dependable substance and the most consumed among all other construction materials. However, the construction industry’s insatiable need for building supplies has led to the widespread exploitation of natural resources like river sand and stone. However, one of the most pressing problems in the construction industry and others nowadays is excessive waste and byproducts. Promoting ecological control and the goal of sustainable progress has put environmental pressure on all businesses, including construction, to embrace eco-friendly practices. Environmentalists’ concerns about the dangers posed by the widespread use of natural resources in building construction are growing. In some instances, construction debris may be harmful to the environment. Global building growth and redevelopment plans have worsened demolition in the construction industry. The demand for construction materials is increasing yearly due to urbanism, but their costs are rising simultaneously. Using industrial waste like polymers and rubbers and natural waste like olive stones and pumice stones to replace cement, fine aggregate, and coarse aggregate to reduce building costs conserves natural resources from exhaustion and protects the environment from waste impact and risks. The current research shows how waste can be used to replace materials on construction sites and the impact of the properties of these materials on the quality of concrete.

Authors: Могілевський Сергій , Жовтоштан Марія , Бушуєва О. В.
Published: March 2023

Актуальність. Для корекції аметропій використовують методи рефракційної хірургії, з яких Laser In Situ Keratomileusis (LASIK) у 80%–85% – процедура вибору. Синдром сухого ока (ССО) – найчастіше ускладнення LASIK, частота якого сягає 20% через 6 місяців після втручання. Персистуючий ССО після LASIK здатний викликати гіперплазію епітелію, що може бути пов’язана з міопічним рефракційним регресом.Мета: дослідити вплив персистуючого синдрому сухого ока після ексимерлазерної корекції міопії на віддалені функціональні результати.Матеріали й методи. Спостерігали за 65 пацієнтами (130 очей), яких поділили на 2 групи залежно від методу ексимерлазерної корекції (ЕЛК) – LASIK і FemtoLASIK. 40 людей (80 очей) – контрольна група. Пацієнтам перед операцією і протягом спостереження аналізували маніфестну рефракцію, кератотопографію, AS-ОСТ, сльозопродукцію, стабільність слізної плівки, профарбовування очної поверхні. Термін спостереження – 6 місяців.Результати. У пацієнтів з діагностованим ССО спостерігався міопічний регрес у межах 0,5±0,1 D. Його частота серед усіх пацієнтів – 10,7% через 6 місяців після ЕЛК. У них спостерігалося потовщення епітелію на 7,9±0,25 мкм у центральній ділянці, у зоні 5–7 мм потовщення епітелію було 2±0,3 мкм, посилювалася іррегулярність рогівки під час виміру іррегулярності рогівки (CIM – Corneal Irregularity Measurement) на кератотопограмі, що зросла до 3,01±0,12 мкм, і ступінь профарбовування поверхні ока підвищився з 0,22±0,08 до 2,3±0,08. Серед пацієнтів, які не мали ССО, не відмічали рефракційного регресу, профарбовування поверхні в термін 6 місяців після ЕЛК міопії, СІМ був у межах 0,49–1,68 мкм. Товщина епітелію в центрі перевищувала периферичну не більше ніж на 2,5±0,3 мкм. Маніфестна рефракція коливалася в межах +0,12±0,1 D. Висновки. Виявлено 10,7% серед усіх пацієнтів із персистуючим ССО після ЕЛК міопії, у яких зафіксували рефракційний регрес у межах 0,5±0,1 D. Потовщення епітелію в центрі рогівки після ЕЛК у пацієнтів без ССО менше на 37,5%, ніж у пацієнтів із персистуючим ССО. Товщина епітелію рогівки менша при міопії на 6,4%, ніж за відсутності аметропій. Кератотопографічні дані виявляють нерегулярний астигматизм при ССО, який знижує якість зору, і пов’язані зі змінами товщини епітелію, рефракційним регресом після ЕЛК міопії. Профарбовування поверхні рогівки – доказ пошкодження епітелію рогівки при персистуючому ССО після ЕЛК міопії.

Imperial Executive, Cost of Governance and The Challenge of Development in Nigeria’s Fourth Republic
Authors: Abubakar Oladeji
Published: March 2023

There are raging debates about Nigeria's high cost of governance and its effects on socioeconomic development. Indeed, one of the talking points of the contemporary restructuring discourse is the need to drastically cut the cost of governance to allow more resources to fund the development of critical infrastructure. Understandably, the emphasis is always on the structure of governance of the executive presidential system and the bloated civil service. Indeed, much of the issue, however, is on the Executive, its imperial nature, its idiosyncrasies, and its style of governance. This paper assesses the features of the 'imperial executive' in Nigeria and the extent to which executive profligacy aggravates the cost of governance and hinders socioeconomic development. Using essentially secondary data, the paper found that the higher the recurrent expenditure, the more difficult it is to allocate adequate resources to capital expenditure in Nigeria. This scenario implies that a large chunk of public fund expenditure on the political elite makes it impossible to allocate adequate resources to other critical areas of development such as health, education, infrastructure etc. The paper suggests critical reforms in the structure of the executive presidential system as well as mechanisms to check the excesses and idiosyncrasies of the Executive in Nigeria.

Role of Micro-Finance in India- A Conceptual Study
Authors: Maurya Shivani
Published: March 2023

Micro-finance plays an important role in rendering financial services to financially and economically backward people. It has many social as well as economic implications such as curtailment of poverty, improvement in standard of living, financial literacy, women empowerment and economic growth of the nation. Micro-finance not only provides microcredit but also various services like deposits, insurance, money transfer, payment services, saving, etc. In a developing country like India where a large portion of the population is living below poverty and a large number of people are unable to get access to traditional banking services, the importance of microfinance cannot be undetermined. With the aim of developing financial inclusion and equality, the idea of micro-finance acts as an alternative source to provide loans to poor people. This research paper is based on secondary data which discusses the concept of micro-finance and also focuses on identifying the current scenario and the role of micro-finance in the growth and development of India.
Revisiting dissipative motion of a spinning heavy symmetric top and the rise of the top by friction
Authors: Tanriverdi Vedat
Published: March 2023

The dissipative motion and the rise of a heavy symmetrical top with a hemispherical peg are studied. A model taking the fixed point of the top as the center of the peg is considered when the top completely slips and the rolling motion is ignored. This is different from existing models like Jellet's one. Jellett's model and pure slipping are compared for different tops for the rise of the top, and an experimental method to determine the better model is proposed.
Investigation using Monte-Carlo codes simulations for the impact of temperatures and high pressures on thin films quality
Authors: Bouazza Abdelkader
Published: March 2023

The quality of thin films represents the key to any improvement made in the device components manufacturing, and the way to obtain this quality based on deposition parameters takes the attention of our group. In this work, using the sputtering technique in the context of the Monte-Carlo approximation, an investigation of the effect of temperature and elevated pressure on the number of ejected particles and hence their deposition and the creation of finest thin films are applied. A vacuum chamber with 30x30x50 cm in dimension holding a magnetron which has a 2 cm in radius circular target was created. Inside this chamber, 105 particles of Argon (Ar) followed by the same number of xenon (Xe) gas are injected. This target moves away by 15cm from the substrate (with 7 cm in radius), containing three materials (Silicon (Si), germanium (Ge), and copper (Cu)) widely used in advanced technologies as in electronics and photovoltaic cells panels. Evident and satisfactory results were obtained, demonstrating that increasing pressure (0.5, 2, and 5 Pa) for both gases drops off in a spectacular way the total number (with different values) of the material particles reaching the substrate and disrupting the morphology of the thin films. moreover, and contrary to pressure, it has also been proved that mounting gas temperatures of 100, 300, and 600 K, representing three different states in kelvin degrees, where 100 K-173°C for the low (cold), 300 K27°C for the regular (atmospheric) and 600 K327°C for the high (warm) instances, supply a large number of materials atoms in substrate-level which conduct to the finest quality of the thin films. In addition, germanium gives the best results compared to silicon and copper.
