Dermatological disorders are common medical conditions that impact an individual's skin and mucous membranes. Their primary symptoms include redness, itching, rashes, and sometimes even deformity. Skin disorders come in a wide range of forms, from common conditions like eczema and acne to more serious conditions like dermatitis and psoriasis. The goal of the study is to assess prescription pattern of pediatric population diagnosed with any skin disease. An observational descriptive study was carried out among 120 samples in the Out-patient Department of Dermatology, ESIC MC - PGIMSR & Model Hospital, Rajajinagar, Bengaluru. The data was collected by using self-designed data collection form. All information’s were processed and analyzed by using Microsoft excel. It was found that out of 120 subjects included in the study, higher percentage was in males (54%) than females (46%) in which age group (12- 18, n= 75) was in majority. In this study Non-infective (46.67%) diseases were more compared to Infective diseases (36.30%), infestation (6.67%) and miscellaneous (10.37%). The most common route of administration was Topical route 69% (n= 251), in which the most common one was cream 36.6% (n= 135). Antifungals, 24.1% (n=88) were counted as the most prescribed in the list of common categories of drugs followed by antihistamines, antibiotics, corticosteroids. In the antifungals, fluconazole 3.84% (n=14) was the most prescribed in oral route and ketoconazole 7.12% (n=26) was the most prescribed in topical route. Out of 120 subject, 39 were prescribed with 4 or more drugs, this makes 32.5% of the total prescription having polypharmacy. The combination therapy (19.7%) is than that of monotherapy (80.3%). A total of 12 drugs were listed in NLEM 2022, out of which only 7 topical drugs were found to be prescribed in the current study. Out of the total 36 topical drugs used in the department, 29 drugs were found to be not listed in NLEM-2022. The prescription pattern study in pediatric skin disease provides important information about how children with dermatological conditions are currently treated. The results emphasize the variety of drugs that are prescribed and the complexity of pediatric skin conditions. The most preferred prescribing therapy was monotherapy. Topical rote of administration was the most prescribed, it might be because of the onsite action and less side effects of topical medications compared to other route of administration.

Advancing Educational Effectiveness with Differentiated Instruction-From Theory to Practice
Authors: - Revati N, Ph.D.
Published: December 2024

Differentiated instruction has become increasingly essential in higher education due to the diverse backgrounds and prior knowledge of students. Unlike the learning styles theory, which advocates aligning teaching methods with individual learning preferences, differentiated instruction focuses on strategies backed by credible evidence. Recent research has debunked the effectiveness of learning styles theory, highlighting its lack of scientific validation and its contribution to the persistence of myths in educational psychology. This paper highlights the importance of addressing students’ readiness levels as a cornerstone of differentiated instruction, rather than relying on unproven preferences or learning styles. It also explores strategies for implementing differentiated instruction effectively. These include assessing student readiness, adjusting instructional content, processes, and outcomes, and fostering collaborative and autonomous learning environments. The paper concludes with an emphasis on integrating teaching practices with real-world applications. When executed effectively, differentiated instruction represents a progressive pedagogical approach that fosters practical learning and transformative knowledge acquisition. By adopting this approach, institutions can enhance their educational effectiveness and prepare students to navigate the complexities of a globalized world.

Authors: - Jaishree , - Vidya Jha
Published: December 2024

The gig economy is transforming the work culture, of organizations across the globe. Technological innovation has brought significant changes to work, organization, and employment relationships with positive and negative impacts. Labor laws, freedom of association, and collective bargaining have long sought to balance the unequal relationship between employers and individual workers and enable workers to act collectively to improve their employment and working conditions. For gig workers specifically, many platforms classify them as independent contractors or partners in place of employees and escape all the responsibilities of an employer. In various jurisdictions this employment classification deters workers from forming unions and engaging in collective bargaining. By exploring different research papers this paper illustrates the changing employer-employee relationship, imbalance of power, and conflicting interests between the employer and the employees emanates the need for evolved Employment Relations. This paper takes insights from the industrial relations background in India and addresses the present employment relations situation in the gig economy.

Authors: Yuksel Beyza , Akbudak M. Aydin
Published: December 2024

All organisms require zinc to sustain their vital functions. In the case of Zn deficiency, plant production, as well as animal and human health, are adversely affected. Baker's yeast (Saccharomyces cerevisiae) is a model organism for scientific research and is commonly used in studies of metal deficiency/toxicity. This study aims to identify the first stage in the identification of Zn uptake genes, which determines the conditions of Zn-deficient environments that inhibit yeast development. The YNB medium, which is the basic nutrient medium for yeast cultivation, contains enough Zn conducive to yeast growth. Chelating agents (EGTA or EDTA) have been added to the YNB medium to create conditions of insufficient Zn. The yeast strains ZHY3 (Zn uptake gene mutant) and W303 (wild type – WT) were tested in these environments. The growth profiles of the yeasts were compared in nutrient media containing different concentrations of the chelating agents. The concentrations of EGTA and EDTA that inhibited the growth of the W303 strain were determined to be 25 mM and 1.6 mM, respectively, while the concentrations that inhibited the growth of the ZHY3 strain were determined to be 12.5 mM and 0.01 mM, respectively. These findings are significant for understanding the effects of Zn deficiency on different yeast strains and highlighting the importance of Zn uptake genes. It is believed that the identified concentrations and the results obtained will contribute to studies related to Zn uptake and Zn uptake genes.
Identification and Functional Characterization of Glutamate Decarboxylase (GAD) Genes in Potato (Solanum tuberosum L.) and Analysis of Their Expression under Drought and Salt Stress Conditions
Authors: Akbudak M. Aydin
Published: December 2024

Gamma-aminobutyric acid (GABA) plays a critical role in plant stress responses and development by regulating osmotic balance, mitigating oxidative stress, and maintaining cellular homeostasis. Glutamate decarboxylase (GAD) is the first and key enzyme in the GABA biosynthesis pathway. In this study, three distinct GAD genes—StGAD1, StGAD2, and StGAD3—were identified, each distributed on separate chromosomes, indicating non-redundant functional roles. Expression profiling revealed that StGAD1 is the primary stress-responsive gene, with significant upregulation in both roots and leaves under drought stress, promoting GABA accumulation to enhance water-use efficiency and reduce oxidative damage. In contrast, StGAD2 showed limited involvement, maintaining basal GABA levels but displaying minimal stress-induced expression. Protein-protein interaction analysis highlights functional relationships among the GAD proteins, with StGAD1 and StGAD2 sharing significant homology. The findings suggest that GABA metabolism, primarily driven by StGAD1, plays a more prominent role in drought tolerance than salt stress adaptation, where other regulatory mechanisms such as ion homeostasis may be more critical. This study provides foundational insights into the molecular mechanisms of GAD-mediated stress responses in potatoes, offering potential avenues for enhancing crop resilience through targeted genetic strategies.

Authors: Palamarchuk Vitalii , Krychkovskyi Vadym
Published: December 2024

The article presents the results of studying the influence of sowing dates on the formation of elements of the yield structure, productivity and starch content in the grain of maize hybrids of different maturity groups. The research was conducted in the conditions of LLC "Organic-D" in the village of Sutisky, Vinnytsia region, during 2021-2022. The soils of the experimental plot are gray forest soils with medium loamy texture and slightly acidic reaction of the soil solution. The content of the main nutrients is typical for this type of soil. In the research, corn hybrids Amaros (FAO 230), Canyons (FAO 230), P9071 (FAO 280), Bogatyr (FAO 290), P9170 (FAO 320) and Burito (FAO 390) of different maturity groups were used in three sowing dates depending on the soil temperature at the depth of seed placement: early - +6-8°C, middle - +8-10°C and late - +10-12°C. It was found that the elements of the yield structure of the studied maize hybrids depended on the genetic characteristics of each hybrid and varied depending on the use of different sowing dates. The best conditions for the formation of the productivity of the studied maize hybrids in terms of the supply and distribution of heat and moisture resources were in 2021 compared to 2022, which ultimately affected the accumulation of starch in the grain and the level of yield. The highest values of cob length, number of grains per cob, weight of grains per cob, weight of 1000 grains were obtained, on average, in the experiment, when using early sowing - 18.9 cm, 469.5 pcs, 149.2 g, 276.1 g, while the use of the middle sowing period provided a cob length of 18.3 cm, 455.8 pcs., 140.7 g, 261.5 g and late sowing - 17.9 cm, 419.2 pcs., 128.5 g, 254.1 g, respectively. The use of early sowing (at a soil temperature of +6-8°C) allowed to form a yield, on average over the years of research, at the level of 7.87 t/ha, medium (at a soil temperature of +8-10°C) - 7.23 t/ha and late (at a soil temperature of +10-12°C) - 6.60 t/ha. The use of early sowing dates contributed to the formation of the amount of starch in the grain of the studied maize hybrids at the level of 71.33%, medium - 71.84% and late - 72.54%. That is, the delay in sowing dates from early to late to some extent increases the accumulation of starch in the grain, but due to a decrease in yield, the total starch yield of such crops is lower than in early crops. Delayed sowing leads to a decrease in starch yield per unit area by 0.415-0.829 t/ha, compared to early sowing.

N45P45K45, 2. N90P45K45, 3. N45P90K45, 4. N45P45K90, 5. N45P45K45 + liming and a control option without fertilizers. Nitroamofosk mineral fertilizer was applied to pre-sowing cultivation. The introduction of mineral fertilizers led to a lengthening of the sunflower growing season and an extension of the period until the crops are ready for harvesting. Yes, otherwise, with the option without fertilizer application, the dosage of sunflower supplements was delayed by 3 days for the application of N45P90K45, for 4 days for the application of N45P45K90, for 5 days for the application of N45P45K45 and N45P45K45 + liming, and for 10 days for the application of N90P45K45. The greatest increases in the height of sunflower plants by phases of growth and development were established on the fertilizer option N90P45K45, where the combination of double application of mineral nitrogen is manifested. In the flowering phase of the sunflower in this variant, its height was 180 cm. The highest field germination of seeds was achieved by the fertilization variants N45P90K45, N45P45K90 and N45P45K45 + liming - 92.0%, and the lowest - from the control variant without fertilization - 86.7%. At the end of the sunflower growing season, the highest plant density was 68,000 plants/ha and the highest percentage of plant survival was the N45P45K45 + liming option, and the lowest was the control option without fertilization. However, the variant N45P45K45 + liming provided the highest number of weeds in the phase of full emergence and leaf formation.

В статье рассмотрен переход к автономному портовому флоту, в частности, применение азимутальных буксиров-автоматов (АБА) оснащенными поворотными магнитными швартовными устройствами (ПМШУ), включающими в себя магнитную секцию (МС), предназначенную для обеспечения жёсткой сцепки между АБА и транспортным судном. Показаны результаты создания объемных моделей ПМШУ и МС в среде автоматизированного проектирования. Рассмотрены особенности строения корпуса судна для дальнейшего применения методики расчета швов сварных соединений. Место зацепления МС с корпусом транспортного судна должно быть рассчитано дня каждого отдельно взятого судна. В расчёте определены несущие способности сварных швов по металлу шва и по металлу границы сплавления без учета вертикального смещения ПМШУ относительно корпуса судна. Сделан вывод о том, что основная нагрузка приходится на сварное соединение. Проведено имитационное моделирование процесса сцепки АБА с корпусом судна. Продемонстрирована визуализация нагрузки на сварное соединение, а также деформации листа корпуса судна.

The article considers the transition to an autonomous port fleet, in particular, the use of azimuth tugs-automate (ATA) equipped with rotary magnetic mooring devices (RMMD), including a magnetic section (MS) designed to ensure a rigid coupling between the ATA and the transport vessel. The results of creating volumetric models of the RMMD and MS in the computer-aided design environment are shown. The features of the vessel hull structure are considered for further application of the methodology for calculating welded joints. The place of engagement of the MS with the hull of the transport vessel should be calculated for each individual vessel. The calculation determines the bearing capacity of welds for the weld metal and for the fusion boundary metal without taking into account the vertical displacement of the RMMD relative to the vessel hull. It is concluded that the main load falls on the welded joint. Simulation modeling of the ATA coupling process to the vessel hull is carried out. Visualization of the load on the welded joint, as well as the deformation of the vessel hull sheet is demonstrated.

Решена задача о профиле скоростей и гидравлическом сопротивлении при стабилизированном турбулентном течении в канале, ограниченном соосными круговыми цилиндрами (кольцевая труба). Такие течения осуществляются за счет создания перепада давления вдоль оси канала, что требует затрат энергии. Для оценки этих затрат необходимо знание профиля скоростей, расходов и коэффициентов сопротивления, которые зависят от режима течения. В расчете использована система уравнений турбулентного движения жидкости, полученная путем обобщения формулы Ньютона для касательного напряжения в жидкости за счет придания ей степенного вида с последующей завистью соответствующего реологического соотношения в тензорном виде и подстановки его в уравнение движения сплошной среды в напряжениях. Область течения состоит из двух пристеночных подобластей, прилегающих к твердым границам потока. Границу между подобластями определяет нулевое значение касательного напряжения, где имеет место максимум профиля скорости. Для искомой величины – скорости – сформулировано уравнение и поставлены граничные условия. Профиль скоростей в потоке получен как решение соответствующей краевой задачи. Результаты решения сравниваются с опытными данными и эмпирическими формулами.

The problem of the velocity profile and hydraulic resistance in a stabilized turbulent flow in a channel limited by coaxial circular cylinders (ring pipe) has been solved. Such flows occur by creating a pressure difference along the channel axis, which requires energy. To estimate these costs, it is necessary to know the profile of velocities, flow rates and resistance coefficients, which depend on the flow regime. The calculatio liquid, obtained by generalizing Newton's formula for tangential stress in a liquid by giving it a power-law form, followed by envying the corresponding rheological relationship in tensor form and substituting it into the equation of motion of a continuous medium in stress. The flow region consists of two near-wall subregions adjacent to the solid boundaries of the flow. The boundary between the subregions is determined by the zero value of the shear stress, where the maximum of the velocity profile occurs. For the target quantity — speed — the equation and boundary conditions were observed. The velocity profile in the flow was obtained as a solution to the corresponding boundary value problem. The solution results are compared with experimental data and empirical formulas.

Работа посвящена вопросам моделирования массообменных аппаратов в составе воздухонезависимых энергетических установок с реализацией растворения диоксида углерода в морской воде методом абсорбции. С целью достижения данной задачи рассмотрено наличие биогенных поверхностно-активных веществ (ПАВ) в морской воде, являющихся продуктами жизнедеятельности морских организмов. На основе литературных данных по распределению биомассы в верхнем слое Мирового океана предложена зависимость концентрации ПАВ от района и выполнено сравнение с экспериментальными данными. Получены зависимости на основе физико-химических процессов, возникающих при барботаже газа и адсорбции молекул биогенных ПАВ на поверхности пузырька. Установлено, что наличие биогенных ПАВ в морской воде приводит к снижению коэффициента поверхностного натяжения, что в свою очередь снижает скорость движения газовой фазы, при незначительном понижении коэффициента массопередачи, в условиях увеличения общей поверхности массообмена. Определено, что в условиях коалесценции и дробления газовых пузырьков снижение объема газовых пузырьков, вызванный снижением минимального и максимального диаметров газового пузырька приводит к преобладанию дробления над коалесценцией, что приводит к увеличению поверхности массообмена при росте числа пузырьков.

The work is dedicated to the modeling of mass transfer apparatuses within air-independent power systems, focusing on the dissolution of carbon dioxide in seawater through the absorption method. To achieve this goal, the presence of biogenic surfactants in seawater, which are products of marine organisms' life activities, is considered. Based on literature data on biomass distribution in the upper layer of the World Ocean, a dependency of surfactant concentration on the region is proposed and compared with experimental data. Dependencies are derived based on the physicochemical processes that occur during gas sparging and the adsorption of biogenic surfactant molecules on the bubble surface. It is established that the presence of biogenic surfactants in seawater leads to a reduction in surface tension, which in turn decreases the velocity of the gas phase, with a slight reduction in the mass transfer coefficient, under conditions of increased overall mass transfer surface area. It is determined that under conditions of coalescence and fragmentation of gas bubbles, the reduction in gas bubble volume, caused by the decrease in minimum and maximum bubble diameters, leads to the predominance of fragmentation over coalescence, resulting in an increase in the mass transfer surface area as the number of bubbles increases.
