The phenotypic consolidation of firstborn cows Ukrainian Red-and-White dairy breed of different lines by conformation type was studied. Cows were evaluated according to the method of linear classification in the herd of breeding farm PAE "Piskivs'ke" Bakhmatsky district of Chernihiv region. The degree of phenotypic consolidation of lines was determined by formulas of Yu. P. Polupan (2005). Regardless of the line representation, the highest degree of phenotypic consolidation was found in the set of traits that characterize udder with coefficients ranging from K = 0.200 (Inganse line) to K = 0.393 (Kevelie line). According to the complex of conformation traits that characterize expression of dairy type in cows, the best were consolidated daughter descendants of Inganse (K = 0.309) and Kevelie lines (K = 0.335). Offsprings of two pedigree lines Siteishn (K = 0.015) and R. Sovering (K = 0.049) have a low degree of phenotypic consolidation by set of dairy-type body parts. A similar situation in determining the degree of phenotypic consolidation was observed for a group of body parts characterizing body development. The best consolidated were animals Inganse (K = 0.267) and Kevelie (K = 0.395), and the worst - Siteshn (K = 0.048) and Valiant (K = 0.042) lines. According to the assessment of descriptive traits within studied lines, following body parts were distinguished by positive values of phenotypic consolidation coefficients : rump height (K = 0.127-273), body depth (K = 0.092-0.328), rear width (K = 0.033-0.363), front udder part attachment (K = 0.041-0.227), dairy type (K = 0.143-0.385), and negative - hooves condition (K = -0.264… -0.046). Analyzing the results of research, it can be argued that practical application of phenotypic consolidation coefficients as objective evaluation criteria will allow in the future to control consolidation of genealogical formations and other breeding groups of animals both by conformation type and another selection traits.

У вирішенні міжнародних і національних аграрних програм пріоритетним завданням є збереження генетичних ресурсів тваринництва і розробка шляхів їх ефективного використання, адже в світі спостерігається явна тенденція до скорочення породного складу одомашнених видів тварин. Тому метою наших досліджень був аналіз та висвітлення сучасного стану племінного м’ясного скотарства в Україні, а також характеристика вітчизняних порід, які є базою для племінної роботи та прогнозування їх значення у породотворному процесі. Для аналізу стану розвитку м’ясного скотарства в Україні було використано Державний реєстр суб’єктів  племінної справи  у тваринництві за 2015 – 2019 рр. Для дослідження використано методи системного узагальнення, графічний, аналітичний та порівняльно-статистичний. Проведено аналіз стану розвитку м’ясного скотарства  в Україні. Показано, що найбільше поголів’я великої рогатої худоби м’ясних порід зосереджено на півночі та заході країни, де природно-кліматичні умови є сприятливими для створення розвинутої галузі м’ясного скотарства. Встановлено, що лідерами за чисельністю являються Волинська та Чернігівська області, а на даний час в Україні  зареєстровано 52 племінні господарства, де розводять м’ясну худобу 11 порід.  Найбільш чисельною серед імпортованих порід є абердин-ангуська порода. Серед вітчизняних порід найбільшою є питома вага волинської та  поліської спеціалізованих м’ясних порід. Показано, що в умовах тривалої кризи за останні роки племінне м’ясне скотарство в Україні зазнало суттєвого скорочення чисельності поголів’я, звуження породної структури та зміни форми власності. Зокрема, за період з 2019 до 2020 року галузь м’ясного скотарства в Україні зазнала втрат – чисельність племінного поголів’я загалом скоротилась на 7%, а окремих порід як симентальської та південної м’ясної скоротилася на 32-60%.

Досліджено тривалість та ефективність довічної продуктивності корів української чорно-рябої молочної породи різної кровності за голштинською породою та чистопородних голштинів вітчизняної селекції заводського стада. У межах генотипів було сформовано чотири піддослідні групи помісних корів з урахуванням умовної кровності за голштинською породою: I група 3/4-кровні; ІІ група – 7/8; ІІІ – 15/16; ІV – 31/32. Встановлено, що кращими показниками продуктивного довголіття відзначалися чистопородні голштини вітчизняного походження порівняно з помісями, одержаними за поглинального схрещування з бугаями голштинської породи. Найдовшою тривалістю життя (2633 дні) та найбільшою кількістю лактацій за життя (5,2) характеризувалися корови з умовною часткою спадковості голштинів 3/4. При порівнянні чистопородних голштинських корів з помісними тваринами І та ІІ груп високодостовірна різниця на користь помісних корів за тривалістю життя становила відповідно 378 та 289 днів (Р<0,001), а за тривалістю лактацій – на 1,3 та 0,9 штук (Р<0,001). Зростання спадковості голштинської породи не спричинило у помісних тварин відповідного зменшення довічного надою. Від групи чистопородних голштинських корів з часткою крові голштина 96,88% було отримано найвищий довічний надій (30327 кг) з перевищенням груп корів решти генотипів на 1575-4615 кг молока з достовірною різницею у порівняннях з помісними генотипами І-ІІІ груп (Р<0,001). З високою достовірністю чистопородні голштини переважали відповідні помісні групи за довічним виходом молочного жиру, відповідно на 68,1-164,6 кг (Р<0,001). Надій чистопородних голштинських корів на один день життя становив 13,4 кг з перевищенням корів інших груп помісних генотипів на 1,2-3,6 кг з високим ступенем достовірності (Р<0,001). Встановлена додатна кореляція між часткою спадковості голштина та тривалістю життя, кількістю використаних лактацій, довічним надоєм, молочним жиром та надоєм на один день життя. Рівень умовної кровності на вміст жиру в молоці не вплинув. Із нарощуванням спадковості голштинської породи кореляційна залежність ознак довголіття від спадковості голштина істотно зменшувалася.

This article mainly reviews the immunomodulatory mechanism of action Astragalus polysaccharide  and its effectiveness in poultry, and provides a theoretical basis for the application and research of Astragalus polysaccharide  in poultry breeding. Astragalus polysaccharide  this is one of the main components of Chinese traditional medicine. However in the modern time Astragalus polysaccharide it is a new type of feed additive that can replace antibiotics in animal husbandry. Taking into account the current situation in modern poultry farming with meat quality, the use of this preparation can significantly affect both the quality and the price of poultry meat. In recent years, there have been more and more studies on Astragalus polysaccharide, and some of the components and biological effects of Astragalus polysaccharide have gradually been recognized by researchers. As a natural plant feed additive, Astragalus polysaccharide can significantly promote the body's non-specific immunity and specific immunity, and improve the body's resistance without causing drug resistance and drug residues. However, there are relatively few systematic studies and related mechanisms on the application of Astragalus polysaccharide in animal production.

У статті представлені результати досліджень м’ясних та забійних якостей качок за різних способів утримання при вирощуванні в підсобних господарствах 2-ої зони радіоактивного забруднення. Теоретично і практично обґрунтовано екологічну безпечність виробництва качиного м’яса за безвигульного та вигульного утримання, як одного із основних продуктів харчування населення, що проживає у регіонах, які зазнали радіоактивного забруднення внаслідок аварії на ЧАЕС. Науково-господарські дослідження з вирощування качок на радіоактивно забруднених територіях проводились у 2011-2012 рр. в селі Христинівка Народицького району Житомирської області. Щільність забруднення території цезієм-137 становила >15 Кі/км2. Для дослідів за принципом пар-аналогів було відібрано 60 голів качок із середньою живою масою 40,6 г кожна (при безвигульному утриманні), з 30-ти денного віку качки були розділені на дві групи залежно від способу утримання – вигульний та безвигульний, по 25 голів у кожній, середня жива маса каченят – 520 г. Піддослідна птиця безвигульного способу утримання знаходилася упродовж дня у загороджі з навісом від дощу та сонця, а на ніч качки переганяли у закрите приміщення. Піддослідні качки (вигульний спосіб утримання) впродовж дня перебували з природним обмеженням на території водоймища 0,4–0,6 га. Для годівлі качок цієї групи заганяли у клітку, а для ночівлі − у приміщення. Обмежені водоймища були бідні природною кормовою базою, тому потребу каченят у поживних речовинах повністю забезпечували за рахунок раціонів. Результатами досліджень доведено, що способи утримання качок впливають на ріст і розвиток птиці, масу патраних тушок, вихід складових частин тушки та накопичення 137Cs у м’ясі птиці. Качки вигульного способу утримання характеризувалися більшою живою масою, кращим розвитком внутрішніх органів, масою патраних тушок, виходом м’язів. Дослідженнями встановлено, що питома активність 137Сs у м’ясі піддослідних качок обох груп не перевищувала допустимі рівні і варіювала у межах 12,9–75,9 Бк/кг. Питома активність 137Сs у м’язах качок вигульного способу утримання була на 21−46 % меншою у порівнянні із м’ясом птиці безвигульного способу утримання. Обґрунтовано екологічну безпечність виробництва качиного м’яса для жителів 2-ої зони радіоактивного забруднення, як за безвигульного, так і вигульного способу утримання, надаючи перевагу останньому.
БІЛОГОЛОВА УКРАЇНСЬКА ПОРОДА ЗА ЧИСТОПОРОДНОГО РОЗВЕДЕННЯ ТА СХРЕЩУВАННЯ
Authors: Войтенко Світлана , Сидоренко Олена
Published: September 2021

Методи чистопородного розведення з породою сільськогосподарських тварин дозволяють зберігати породні особливості, закріпляти бажані ознаки родоначальників у потомстві, консолідувати селекційні групи, поліпшувати продуктивність, але на певному етапі роботи з нею виникає проблема інбридингу та зниження рівня продуктивності, які дуже складно вирішити методами внутрішньопородної селекції. Білоголова українська порода великої рогатої худоби наразі відноситься до вітчизняних локальних популяцій, в якій присутні інбредні тварини та яка з огляду на низькі економічно важливі ознаки не може конкурувати не лише з світовими, але й кращими вітчизняними породами. З урахуванням чого пошук способів підвищення господарськи корисних ознак тварин та зниження гомозиготності популяції відноситься до актуальних проблем сьогодення. Дослідження проведені на поголів’ї худобі білоголової української породи в ТОВ «Подільський господар» Хмельницької області. Вивчали вплив бугая  та року народження на поліпшення господарськи корисних ознак корів за чистопородного розведення, а також можливість використання ввідного схрещування для зниження рівня інбридингу в стаді та підвищення генетичного потенціалу худоби за основними ознаками добору. Для визначення ефективності залучення корів білоголової української породи до виробництва молока на промисловій основі вивчали результативність їх схрещування з джерсейською породою. Основні селекційні ознаки визначали за матеріалами бази даних системи управління молочним скотарством (СУМС «Інтесел-Орсек») станом на 1 січня 2018 року. Встановлено, що різниця між найвищою та найнижчою величиною надою корів білоголової української породи за першу лактацію 2009-2014 років народження становила 584 кг (Р≤ 0,01), при цьому сила впливу року народження на надій первісток становила 9,4 % (р ≤ 0,001), вміст жиру – 18,0 % (р ≤ 0,001), кількість молочного жиру – 9,4%. З’ясовано, що найвищою молочною продуктивністю за 3 лактації характеризувалися дочки бугаїв Орла UA235 і Сома UA6800085660, але в цілому вплив плідника на продуктивність корів неістотний, оскільки внутрігрупова різниця надою між високопродуктивними та низькопродуктивними дочірніми потомками одного бугая за кожну з трьох лактацій перевищує міжгрупову. Сила впливу бугая на надій первісток становила 3,4%. Доведено, що використання ввідного та промислового схрещування підвищує молочну продуктивність у помісних корів, порівняно до чистопородних і можуть бути застосовані як методи підвищення генетичного потенціалу худоби при виробництві молока на племінній та промисловій основі.

Ancient didactic astronomical texts
Authors:   Moscow State Institute of Culture, Fesenko Andrew
Published: September 2021

The article focuses on ancient astronomy as an academic dis-cipline. Antiquity created a holistic image of the world and a cul-ture of thinking, in which the natural and exact sciences and lib-eral arts were not artificially differentiated and remained in har-monious unity, becoming the basis of an interdisciplinary ap-proach in education. Therefore, even the exact sciences were studied literarily from poetic works. On the example of ancient culture, the connection between the astronomical worldview and other components of the mindset is particularly clearly traced. This is crucial in terms of technology since ancient pedagogy contained all the criteria for technological effectiveness. In the Homeric age, the basic mnemonic rules for navigating by the stars, the definition of the conditions for visibility of heavenly bodies in all seasons, the connection of celestial phenomena with the calendar, known since the Cretan-Mycenaean age, were liter-arily recorded in the epic. This trend was further developed in Hesiod’s didactic epic and took shape in the content as a para-digm of astronomical education. The appearance of Cleobulina’s astronomical riddles appeared, which are allegorical in nature and show similarities with the allegories of Homer, took place approximately at the same time. In subsequent periods (from the 5th century BC), the school study of the Homer and Hesiod’s works required writing comments on the astronomical passages of these and later other authors. With the development of natural philosophical doctrines, new methods of presenting astronomical material appeared. The original form of the philosophical epic was replaced by a prosaic form. The reaction to the natural philo-sophical revolution led to a preference for the traditional Homer and Hesiod. Special educational astronomical texts written by such authors as Aratus, Germanicus, Alexander Aetolus, etc. came to exist-ence as a separate group.
Cicero’s writings as learning texts for humanities students: from Augustus Wilkins to Cicero Digitalis

The heritage of the ancient Roman politician, orator and thinker Marcus Tullius Cicero (106 BC – 43 BC), is considered as a set of texts that over centuries have been included in the curricula for humanities students, significantly changing the narrative tradition and detecting a way of understanding what is related to humanities. The key questions for the authors is the following: how and for what purposes was Cicero’s heritage presented to humanities students in educational texts in the first two decades of the 20th and 21st centuries? At the beginning of last century, scholars’ attention to Cicero was largely due to Augustus Samuel Wilkins (1843–1905), Paul Monroe (1869–1947) and his disciple Ellwood Cubberley (1868-1941). Many textbooks compiled by P. Monroe, A.S. Wilkins and E. Cubberley were published one after another. Thanks to the educational books of P. Monroe, A.S. Wilkins and E. Cubberley, different approaches to presenting Cicero's works for educational purposes were developed. It is these approaches that were reflected in educational books for humanists a century later. In Russian textbooks, sourcebooks, and anthologies on history of pedagogy, Cicero was mostly a figure of omission not only in the first decades, but throughout the entire 20th century. At the beginning of the 21st century, many learning books for humanities students appeared. Their authors and compilers consider Cicero as an author who left a conceptual description of pedagogical reality (a detailed description of educational process) and chose a narrative description (description of what happened through the eyes of those who take part in it). We have to regret that the Russian domestic tradition of including Cicero's heritage in the content of humanitarian education has hardly undergone any changes over a century: fragments of his works continue to be presented on a small scale, are practically not grouped according to key issues, and rarely accompanied by pedagogical commentaries. The question of why some texts were selected while others were not, can be asked to every author and compiler who included Cicero's texts in their books for humanities students. The search for answers to this “eternal question” can be associated both with the flexibility of the humanitarian curriculum, and with the personal preferences of the authors and compilers of learning books.
An Analysis of Valid Nodes Distribution for Sphere Decoding in the MIMO Wireless Communication System
Authors: Nguyễn Minh Thường
Published: September 2021

Sphere Decoding (SD) algorithms can achieve a quasi-maximum likelihood (ML) decoder performance over Gaussian multiple input-multiple output (MIMO) channels with much lower complexity compared to the exhaustive search method. The SD algorithm is based on a closest lattice point search over a limited search space (hypersphere). On top of that, QR-decomposition simplifies the SD linear system's matrix to be an upper triangle matrix. The solution solver then is done by searching in the exponentially expanding search tree, started from the top with only a single node then increases by M times every level (in $N_T\times N_R$ MIMO system). Fortunately, the SD algorithm shrinks its hypersphere at every level (once the level node is determined) and phases out a vast number of the candidates, remaining only specific valid nodes in the current considered level. In this work, we proposed the statistical approach for evaluating the adequate number of valid search nodes at every level of the search tree, aiming to optimize the overall computational workload. We use a massive number of inputs patterns and extensive simulation to project the number of remaining valid nodes during the searching process. The simulations have been conducted for $4\times 4$ and $8\times 8$ MIMO systems. Our results indicate that for a particular targeted BER, choosing an appropriate sphere radius is essentially important and the number of necessary calculations increases only at the middle layer and can be generically quantified regardless of the system characteristics. This finding is beneficial for the hardware implementation of the SD, where the number of computational units has to be fixed in advance.

Achieving Sustainable Energy Security in Indonesia Through Substitution of Liquefied Petroleum Gas with Dimethyl Ether as Household Fuel
Authors: Lim Natasya , Felixius Vincent , Weslie Timotius
Published: September 2021

Indonesia has been facing an energy security issue regarding Liquefied Petroleum Gas (LPG) consumption. The rapid increase of LPG consumption and huge import have driven the Indonesian government to develop the alternative for LPG in the household sector. Dimethyl ether (DME) is the well-fit candidate to substitute LPG because of its properties similarities. However, discrepancies in the properties, such as combustion enthalpy and corrosivity, lead to adjustments in the application. Coal is a potential raw material to produce DME, especially in Indonesia, known as the fourth-largest coal producer globally. However, the gasification of coal into DME  brings a problem in its sustainability. To compensate for the emission, co-processing of DME with biomass, especially from agricultural residue, has been discovered. Recently, carbon dioxide (CO2) captured from the gasification process has also been developed as the raw material to produce DME. The utilization of CO2 recycling into DME consists of two approaches, methanol synthesis and dehydration reactions (indirect synthesis) and direct hydrogenation of CO2 to DME (direct synthesis). The reactions are supported by the catalytic activity that strongly depends on the metal dispersion, use of dopants and the support choice. Direct synthesis can increase the efficiency of catalysts used for both methanol synthesis and dehydration. This paper intended to summarize the recent advancements in sustainable DME processing. Moreover, an analysis of DME's impact and feasibility in Indonesia was conducted based on the resources, processes, environmental and economic aspects.

Authors: Kurniawan Robi , Feinnudin Agung
Published: September 2021

This study focuses on the public building in Indonesia that has implemented an energy management system compliant with ISO 50001 standard. The main objectives of this study are to review the implementation of the energy management system in the building, highlighting the main aspect of the ISO cycle deployment and key lessons learned for further dissemination. We performed the study of the implementation of energy management in the building sector based on the ISO 50001 framework that aims to enhance an organization to pursue the continuous improvement of energy management with a systematic approach. Implementing the plan, do, check and act cycle of the ISO’s framework, it is found that the management keeps a strong commitment to continuous improvement. As part of the energy management system cycle, an Investment Grade Audit (IGA) was performed in 2018. Implementing the IGA recommendation, both passive and active designs have been applied in the Slamet Bratanata building. Active design strategies that have been implemented include building automation system utilization, chiller and lighting replacement and Energy Monitoring System (EMonS) application. Implemented passive designs include windows film installation and an efficient room redesigned for optimizing natural light. To implement the ISO 50001 Energy Management System in the building, the energy management team has also held various activities. It includes developing Standard Operating Procedures, appointing a Person in Charge on each floor, conducting capacity building and performing an energy efficiency campaign. It is estimated that the energy management system has succeeded in reducing energy consumption by 613.188 kWh (in 2018–2020) and the Energy Efficiency Index by 129.06 kWh/m2/year in 2020. Furthermore, management energy implementation also reduced greenhouse gas emissions by 539.60 tons of CO2 equivalent. This study provides a reference for energy management in another building for improving its energy performance.

THE IMPACT OF ELSTGEEST AND ALFKE’S QUESTIONING MODEL WITH MANIPULATIVES ON PHYSICS STUDENT TEACHERS’ ABILITY TO GENERATE PRODUCTIVE QUESTIONS
Authors: Siew Nyet Moi , Abdullah Sopiah
Published: September 2021

Question-asking is a basic skill required for the development of students’ thinking. However, the way in which physics teachers conduct laboratory activities do not usually stimulate student thinking by asking productive questions. This study addressed this concern by investigating the physics student teachers’ ability to generate productive questions using the Elgeest’s and Alfke’s questioning model with a set of manipulative learning (EAM) strategy. The manipulative consisted of simple electrical components that could be explored and manipulated. The study investigated if there was a difference in student teachers’ productive questions in terms of number of questions in each category and level of thinking between before and after a lesson using EAM strategy. A further purpose was to find out students’ thought regarding their experiences using the EAM strategy in generating productive questions. A total of 34 Third Year undergraduate physics student teachers took part in the study. They worked in a group of 3-4 to discuss and construct questions before and after the instruction. Student teachers’ generated questions and written reflections were used as data collection methods. Questions were analyzed and classified according to Dillon's (1984) classification of questions: properties, comparisons, and causal relationships. It was found that before learning using the EAM strategy, student teachers tended to ask questions of the properties category. In contrast, students tended to pose causal relationship-type questions following instruction with the EAM strategy. Overall, the students indicated that the EAM strategy had increased their ability to generate productive questions at higher categories and cognitive levels. Physics teachers who conduct laboratory activities could use the EAM strategy to lead students in the generating productive questions that foster their thinking.
Key words: Elgeest’s and Alfke’s questioning model, manipulative, productive questions, physics student teachers, thinking.

Authors: Marushchak Mariya , Maksiv Khrystyna , Krynytska Inna
Published: September 2021

Background: Chronic obstructive pulmonary disease (COPD) represents an important public health challenge. It is a major cause of chronic morbidity and mortality throughout the world. Arterial hypertension (AH) is considered one of the principal COPD-associated comorbidities.
Objective: The study was aimed to assess the role of angiotensinogen (AGT) gene polymorphism in occurrence of AH in patients with COPD.
Methods: The study was conducted among 96 patients of them, Group 1 (25 individuals with COPD), Group 2 (23 individuals with AH), Group 3 (28 individuals with COPD and AH). The control group consisted of the 20 healthy subjects. I/D genotypes of AGT were determined by polymerase chain reaction amplification. Plasma AGT activity was determined photometrically by a commercially available kit.
Results: The results of the study have not demonstrated any significant impact of alleles of AGT genes on occurrence of such disease as COPD, AH and combinations thereof. However, analysis of odds ratio has demonstrated the presence of a trend towards a protective role of the M allele of the AGT gene concerning occurrence of COPD, AH and their combinations (OR=0.90, OR=0.71 and OR=0.56, respectively). At the same time, the presence of the T allele of the AGT gene may increase the risk for occurrence of the above mentioned disease (OR=1.11, OR=1.4 and OR=1.79, respectively).
Conclusion: The study suggests that the presence of Т allele of the AGT gene at position 235 of the peptide chain both in homozygous and heterozygous state may increase the risk for AH in patients with COPD.

Published: September 2021

Background: Haematological malignancy and its treatment produce multiple symptoms that significantly distress patients and impair function. Symptoms caused by treatment may delay treatment or lead to premature treatment termination and residual treatment-related symptoms often complicate post treatment rehabilitation. When treatment is no longer possible, symptom control becomes the focus of cancer care.
Objectives: The study was aimed to determine the symptom burden of the haematological malignancy patients.
Methods: A cross sectional study was conducted from July 2015 to June 2016 among the haematological malignancy patients. A total of 316 haematological malignancy adult (age ≥18 years) patients were purposively selected from haematology department of two tertiary level of hospitals in Dhaka city. Face to face interviews were taken from the diagnosed haematological malignancy patients admitted in the hospital and attending outdoor using questionnaire based on symptom distress scale (SDS).
Results: Mean age was 39 years and most of the patients suffering from Acute Leukemia 162(51.3%). Mean monthly family income was around 22235 taka and 120(37.9%) patients were unemployed. Patients with haematological malignancy had a considerable physical and psychological symptom burden which ranged from 94.3% for fatigue to 8.5% for difficulty in concentration. Physical symptoms such as fatigue 127 (40.2%), change in appetite 86 (27.2%), pain1 81 (25.6%), insomnia44 (13.9%) caused severedistress and psychological symptoms include change in appearance 37 (11.7%) and outlook 33 (10.4%) were sever distressing. Significant association (p<0.001) was to be found between occupation and symptom distress where 82 (68.4%) unemployed and 51 (66.3%) housewife had moderate/sever symptom distress. Respondents who managed their treatment expenditure by loan and asset sell 11 (84.6%) had significant(p=0.004) moderate/sever distress. Patients having less than one month of diagnosis 47(72.3%) and admitted in inpatient 114 (66.6%) had significant higher moderate/sever symptom distress(p=0.03) and (p<0.001) respectively.
Conclusion: Patients with haematological malignancy were likely to have multiple symptoms and comprehensive symptom assessment was suggested throughout. The introduction of supportiveor palliative care services during times of increased symptom burden may assist haematologists and other careers in the management of their patient’s distress and quality of life.

Published: September 2021

Background: Occupational noise is considered as a global problem with social and physiological impacts, causing noise-induced hearing loss (NIHL). High levels of occupational noise is a problem in all regions of the world. Road traffic produces high noise levels that can cause damage to the traffic police hearing. Hence, occupational hearing loss is a well-known outcome of noise exposure at work.
Objectives: The study aimed to measure the noise exposure level at different traffic points and determine the occurrence rate and severity of hearing loss among the traffic police of Dhaka Metropolitan City.
Methods: This cross-sectional study was conducted during 2017-2019 in 28 selected traffic points of Dhaka Metropolitan City under four traffic zone (East, West, North, and South) and among 100 traffic police who were working there and met the inclusion and exclusion criteria. Noise exposure level was measured from all selected traffic points with a digital sound level meter. Data were collected by face to face interview with a pretested semi-structured questionnaire followed by an otoscopic examination, tuning fork tests, and a baseline audiogram. To see the association, Chi-square tests or Pearson’s correlation coefficient (r) tests were performed.
Results: This study revealed that the average noise exposure level at East, West, North, and South zones are respectively 125.6 dB, 112.9 dB, 121.3 dB, and 119.4 dB. At every point, the noise exposure level was more than the acceptable limit set by the Occupational Safety and Health Administration (OSHA). In the audiometry report of 100 traffic police, 64% had sensorineural hearing loss. Of them 85% had mild, 9% had moderate and 6% with severe hearing loss. Notch in 4 kHz in an audiogram was present in the right ear of 46% of respondents and left ear of 52% respondents. It was observed that hearing loss was significantly associated with increasing age and job duration.
Conclusion: Traffic police of Dhaka Metropolitan City is in constant risk of noise induced hearing loss as the ambient noise of this city is very high. Regular assessment and hearing screening is recommended for all the traffic police who are exposed to noise.

Background: Teamwork is one of the most fundamental factors in rehabilitation medicine. Although isolated physicians and therapists are working with rehabilitation services in Bangladesh, there is limited data for understanding the effects of a team effort.
Objective: To evaluate the effect of rehabilitation team meeting on the patients’ disability in the Department of Physical Medicine and Rehabilitation (PMR) in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka.
Methods: This was a randomized controlled trial conducted in the Department of Physical Medicine and Rehabilitation (PMR) in Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka from September 2018 to October 2019. Two hundred and thirty nine patients attending the PMR department for comprehensive management of disability (such as disability in mobility, speech, self-care, sphincter control etc.) were purposively selected for the study. Patients were randomly allocated by lottery in two groupsgroup A (received Rehabilitation Team Meeting service) and group B (received conventional Rehabilitation treatment). The meeting comprised physiotherapist, occupational therapist, rehabilitation nurse, speech and language therapists, social worker, nutritionist, psychologists under the team leader guidance by physiatrist. Respondents of both groups were assessed to see the effects of treatment at 6th weeks, 12th weeks and 24th weeks. Among 239 patients, 77 patients in group A and 71 patients in group B had completed 24th week follow up. Outcomes were measured by FIM (Functional independence Measure) scores.
Results: The mean age of the patients in group A and B were 42.2 (±17.5) years and 45.7 (±14.6) years respectively. In both groups, majority of the patents were male and came from urban areas. Main cause of disability was stroke while others had traumatic brain injury, spinal cord injury, spinal cord compression, rheumatoid disease and others. At baseline and after 6th week of treatment, there were no significant statistical differences between the two groups (p>0.05) regarding FIM scores. In 12th week, FIM significantly increased in group A (p=0.009) compared to group B which persisted till 24th week (p<0.001).
Conclusion: Rehabilitation team meeting significantly reduce disability of the patient. It needs to work continuously to build up the rehabilitation team to improve physical rehabilitation in Bangladesh to ensure total care of the disabled.

Lepton Flavor Violating μ- - e- Conversion: An Overview
Authors: Verma P. , Vivekanand - , Chaturvedi K.
Published: September 2021

The search for lepton flavor violation in charged lepton decays is a highly sensitive tool to look for physics beyond the Standard Model. Among the possible processes, µ-decays are considered to have the largest discovery potential in most of the standard model extensions. Many searches have been performed in the past, but no evidence has been found so far. In this paper, we have reviewed the current theoretical and experimental status of the field of muon to electron decay and its potential to search for new physics beyond the Standard Model. Future prospects of experiments for further progress in this field are also discussed.

Authors: Das U. J.
Published: September 2021

The main objective of this study is to investigate the effects of the Casson fluid parameter on an incompressible, magnetohydrodynamic boundary layer flow of a Casson fluid past a moving porous inclined plate in the presence of heat source and first-order chemical reaction. The governing partial differential equations are converted into ordinary differential equations using similarity transformation and then are solved numerically, adopting bv4pc method. The effects of relevant parameters on the velocity, temperature and concentration profiles are analyzed graphically. Also, tabular form is used to present skin friction, heat transfer and mass transfer. This investigation reveals that the Casson fluid parameter enhances the fluid velocity, skin friction and Sherwood number, while the Nusselt number decreases.

Authors: Gupta P. , Kumar N.
Published: September 2021

In this present paper, an M/M/1 retrial queueing model with a waiting server subject to breakdown and repair under working vacation, vacation interruption is considered. Customers are served at a slow rate during the working vacation period, and the server may undergo breakdowns from a normal busy state. The customer has to wait in orbit for the service until the server gets repaired. Steady-state solutions are obtained using the probability generating function technique. Probabilities of different server states and some other performance measures of the system are developed.  The variation in mean orbit size, availability of the server, and server state probabilities are plotted for different values of breakdown parameter and repair rate with the help of MATLAB software. Finally, cost optimization of the system is also discussed, and the optimal value of the slow service rate for the model is obtained.

Published: September 2021

Breast cancer (BC) is the most common cancer for females, and its incidence tends to increase year by year. Currently, the backbone of therapy for BC is mainly chemotherapy; however, its toxicity in normal cells and acquired tumor resistance to the drug users are considered the main barriers. Therefore, there is still an urgent need for the development of more effective and safer anti-BC agents. Based on previous reference documents in recent years, this review covers the work reported on the anti-BC compounds classified according to the structures. This review summarized significant anti-BC compounds organized by functional groups according to the animal model data, although there would be some limitations. This review highlights the properties of new compounds having promising anti-BC properties, which may be proven to be more effective and selective, and possibly free of unwanted side effects. The reviewed compounds represent an interesting possibility of overcoming BC and reducing the percentage of patients with an inadequate response to drug therapy.
Effect of 1-Acetyl-1H-Benzotriazole on Corrosion of Mild Steel in 1M HCl
Authors: Kamble P. P. , Dubey R. S.
Published: September 2021

The corrosion inhibition study of  1-acetyl-1H-benzotriazole (ABTZ) on mild steel in 1M HCl solution has been investigated using different techniques like weight loss, open circuit potential (OCP), and potentiodynamic polarization. Results showed that ABTZ inhibited mild steel corrosion in acid solution and indicated that the inhibition efficiencies increased with the increase in inhibitor concentration. The polarization curves revealed that the studied compound behaved as a mixed-type of inhibitor. The adsorption of the inhibitor on the surface of mild steel in the corrosive environment followed the Langmuir isotherm. The presence of thin film formed due to adsorption of ABTZ on mild steel surface is further confirmed by scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDAX).
Sensitivity Analysis of PBL Physics Schemes of WRF-ARW Model in Simulating the Tropical Cyclone ‘TITLI’ (2018) Over the Bay of Bengal
Authors: Saifullah - , I. Ali M.
Published: September 2021

Tropical Cyclone (TC) is the most destructive weather phenomenon in the Indian sub-continent. To mitigate the destruction due to TC better prediction is needed. So, the study of sensitivity of different physical schemes in WRF-ARW model with intensification and track of TC is important. In this study, sensitivity of Yonsei University (YSU), Asymmetric Convective Model version 2 (ACM2), Bougeault-Lacarrere (Boulac), Medium-Range Forecast (MRF), Mellor-Yamada Nakanishi and Niino Level 2.5 (MYNN2.5) and Level 3 (MYNN3) Planetary Boundary Layer (PBL) schemes are used to simulate the TC ‘Titli’ which made land fall near Palasa in North Andrha Pradesh and South Odhisha coasts at 0000 UTC of 11th October. National center for environmental prediction Global Final Reanalysis (FNL) data have been used as an initial and lateral boundary conditions. Variation of heat flux, latent heat flux and moisture flux with time for these schemes are shown which are responsible to intensify the TC. Model simulated intensity i.e., minimum central pressure, maximum sustained wind speed at the surface (10 m) and track are compared with the India Meteorological Department (IMD) estimated value. It can be specified that the Boulac, MYNN2.5 and MYNN3 schemes simulate the better intensity and track of TC ‘Titli’.
