Background: The higher temperatures resulted due to global warming might bring about changed geographical distribution of crops and even in the season. In other words, heat stress is likely to be an eventual challenge for crop production in general and for potatoes in particular. Thus, imparting heat tolerance in potato cultivars is of utmost importance. Methods: The experiment was conducted in pots and the ambient temperature was approximately 33±0.5oC which constitutes heat stress for potato crop. Potato cultivars namely Kufri Ashoka (relatively heat susceptible) and Kufri Surya (relatively heat tolerant), cultivars, were used in this experiment. The observations were made on the fourth leaf from the top of the mother shoot in potted plants which was fully expanded; data collected were subjected to statistical analysis by using analysis of variance under completely randomized design. Result: Data recorded on different morphological and stomatal attributes indicate that there was significant difference between susceptible and tolerant cultivars of potato wherein Kufri Surya showed better shoot/root ratio, stomatal density as well as stomata index as compared to Kufri Ashoka.

Background: Scheduling of irrigation is the major factor in producing higher yields of summer crops. Water stress during the sensitive stages will cause significant reduction in yield. Potassium (K+) is reported as an important element in reducing the ill effects of crop water stress. Foliar application of potassium increases the drought tolerance in mungbean. Keeping this in view, a field experiment was conducted to study the response of summer mungbean to foliar potassic fertilization under different moisture regimes during 2018 at SVPUAT, Meerut (U.P). Methods: It included 12 treatment combinations comprised of 2 irrigation schedules (0.6 and 0.4 IW/CPE ratio) and 6 foliar potassium treatments (1% spray of K through KNO3 and/or KCl at flowering, flowering and pod development stage including control), replicated thrice and were tested under a split-plot design. Result: The results indicated that, the growth parameters, yield and yield attributes of mungbean were significantly higher under 0.6 IW/CPE ratio as compared to 0.4. The gross returns, net returns and B:C ratio were also found highest with 0.6 IW/CPE ratio. Among the foliar application of potassium treatments, the growth attributes, yield and yield attributes were significantly increased by foliar application of 1% K through KNO3/KCl at flowering and pod development stage. The foliar application of 1% K through KNO3 at flowering and pod development stage fetched significantly higher gross returns, net returns and B:C ratio, but remained on par with dual spray of 1% K through KCl. The interaction effect between irrigation regimes and potassium foliar levels was non-significant for most of the parameters.

<p class="Abstrak">Spesifikasi keamanan sangat penting bagi pengembangan aplikasi <em>chatting</em> karena dapat menentukan tingkat keamanan aplikasi yang tentunya akan berdampak pada kepercayaan pengguna. Namun, pengembangan fitur keamanan pada aplikasi yang beredar belum semua didasarkan pada suatu spesifikasi kebutuhan keamanan yang jelas. Misanya, aplikasi Mxit dan QQ Mobile tidak memenuhi satu pun dari tujuh kategori keamanan untuk <em>secure chat</em> yang dikeluarkan oleh Electronic Frontiers Foundtaion (EFF). Bahkan, Yahoo! Messenger belum menerapkan disain keamanan yang baik, misalnya kita tidak dapat memverifikasi identitas kontak kita. Selain itu, Yahoo! Messenger tidak menerapkan <em>perfect forward secrecy</em>. Artinya, fitur keamanan pada beberapa aplikasi<em> chat</em> dikembangkan tidak berdasarkan pada rancangan spesifikasi keamanan. Pada penelitian ini, dilakukan perancangan spesifikasi keamanan untuk pengembangan aplikasi <em>secure chat</em> dengan mengacu pada <em>Common Criteria for IT Security Evaluation Version 3.1:2017</em>.  Pada hasil rancangan tersebut, telah ditentukan 28 famili dari 7 kelas <em>Secure Functional Requirement</em> (SFR) yang harus dipenuhi dalam pengembangan aplikasi secure chat. Hasil rancangan telah divalidasi dengan metode <em>expert judgment</em>.</p><p class="Abstrak"><em><strong>Abstract</strong></em></p><p class="Abstrak"><em>Security specifications are very important for chat application development because they can determine the level of its security which, of course, will have an impact on user trust. However, the development of outstanding application security features is not all based on a clear security requirement specification. For example, the Mxit and QQ Mobile applications do not meet any of the seven security categories for secure chat issued by the Electronic Frontier Foundation (EFF). In fact, Yahoo! Messenger has not implemented a good security design, for example, we cannot verify the identity of our contacts and do not apply perfect forward secrecy. This means that security features in some chat applications are developed not based on security specification designs. In this study, the design of security specifications for secure chat application development was carried out by referring to the Common Criteria for IT Security Evaluation Version 3.1: 2017. In the design results, 28 families of 7 classes of Secure Functional Requirements (SFR) have been determined that must be met in the development of secure chat applications. The design result has been validated using expert judgment method.</em></p>

This paper presents a method for reducing the cogging torque for a sloping notch with two notches applied on the stator teeth. The accuracy of FEA was confirmed by a comparison with a previous model using an asymmetric notch for the experiment data and 3D FEA results, followed by a comparison of the cogging torque of a two notches model and a sloping notch model. The sloping notch model was modified to a step-sloping notch model in consideration of a potential manufacturing process. The optimal design for minimizing the cogging torque was developed considering the sloping degree, angle, position, and size of the notches. As the optimal design result, the cogging torque on the optimal model was reduced. Finally, the analysis and optimal design results were confirmed by FEA.

В настоящее время ведущим элементом эдьютейнмента стали технологии анимации. Поскольку сам эдьютейнмент в большей степени предназначен для детского образования, то становится понятной предпочтительность данной технологии. Вместе с тем развлекательные и сюрпризные формы нашли свое применение и в образовании взрослых, в частности в создании различных ресурсов «цифрового» образования. Такой спектр реализации эдьютейнмента – от образования детей до образования взрослых – ставит проблему определения границ применения используемых способов визуализации. Для диагностики этих границ, имеющих семиотическую сущность, релевантностью обладают позиции и методологические инициативы педагогической биоэтики. Эти позиции и инициативы продиктованы определением взаимосвязи этических, коммуникативных и ценностных пределов различных локусов в образовательном пространстве, устанавливаемых с целью защиты индивидуальных жизненных ориентаций субъектов обучения и воспитания. Отмеченные обстоятельства отвечают направлениям модернизации образования: развитие современных детей с их собственным взглядом на мир, с их особенностями восприятия и усвоения нового опыта, знаний и умений, – а также отвечают социальным запросам к современному образованию: формирование личностей с уникальными способностями, прежде всего способностями к уникальной рецепции, акцептуации и интерпретации. Развитие этих способностей и, следовательно, формирование навыков игры разных коммуникативных ролей и самостоятельного выбора своей роли становятся способом адаптации к условиям неопределенности социальных сценариев, то есть к условиям настоящего и прогнозируемого будущего, в которых происходит жизнь современного человека. Анимация в качестве элемента эдьютейнмента считается универсальным образовательным инструментом, максимально приспособленным к трансляции игровых интерактивных методик обучения. Анимация очень важна для повышения эффективности наглядного обучения. Кроме того, довольно трудно выбрать вид визуального искусства, так пересекающий тезаурусы учеников, их законных представителей, будущих учителей и учителей. Представленные акценты в установленных резонансах эдьютейнмента и педагогической биоэтики позволили определить условия разработки образовательных технологий визуализации: визуализация служит только разъяснению, но не доказательности; в основе разработки должны быть заложены конкурирующие теории; результат разработки воплощает консенсус теоретической конкуренции. Currently, animation technologies have become the leading element of edutainment. Since edutainment is intended more for children’s education, the preference of this technology becomes clear. Entertaining and surprising forms have also found their application in adult education, in particular, in the creation of various resources for “digital” education. Such a spectrum of implementation of edutainment (from the education of children to the education of adults) poses the problem of determining the boundaries of the application of the visualization methods used. The diagnosis of these boundaries has a semiotic essence. Positions and methodological initiatives of pedagogical bioethics are relevant for the diagnosis of these boundaries. These positions and initiatives are dictated by the definition of the relationship between ethical, communicative, and value limits of various loci in the educational space. The limits are established in order to protect individual life orientations of subjects of training and education. The noted circumstances correspond to the directions of modernization in education: the development of modern children with their own view of the world, with their peculiarities of perception and assimilation of new experience, knowledge, and skills. The circumstances also meet the social needs of modern education: the formation of individuals with unique abilities, first of all, the ability for unique reception, acceptance, and interpretation. The development of these abilities and, consequently, the formation of the skills of playing different communicative roles and the independent choice of one’s role becomes a way of adaptation to the conditions of uncertainty in social scenarios, that is, to the conditions of the present and the predicted future, in which the life of a modern person takes place. As an element of edutainment, animation is a universal educational tool maximally adapted to broadcasting game interactive teaching methods. Animation is very important to improve the effectiveness of visual learning. In addition, it is rather difficult to choose a type of visual art that overlaps the thesauri of students, their legal representatives, future teachers, and teachers as much as animation does. The presented accents in the established resonances of edutainment and pedagogical bioethics made it possible to determine the conditions for the development of educational visualization technologies. These conditions are: (1) visualization serves only for clarification, but not for evidence; (2) competing theories should be at the core of development; (3) the design result embodies the consensus of theoretical competition.

Background: Being an efficient N- fixer, mungbean improve the soil fertility status and can thereby serve as a useful component in any viable cropping system in the country. PROM has to be a better source of phosphate application. Indian soils are deficient in organic carbon. Sulphur is mostly applied to oilseed and pulse crops found to benefit more than one crop in a sequence due to its significant residual response. Methods: The investigation was conducted during kharif season of 2019 comprising five levels of phosphorus sources (Control, 16 kg P2O5/ha through DAP, 16 kg P2O5/ha through PROM, 32 kg P2O5/ha through DAP and 32 kg P2O5/ha through PROM) and three levels of sulphur (Control, 15 and 30 kg/ha) making 15 treatment combinations replicated three times in factorial randomized block design. Result: Application of 32 kg P2O5/ha through PROM recorded significantly higher growth, yield attributes, yields as well as net returns ( 50440) with B:C ratio 2.93 as compared to 16 kg P2O5/ha through DAP, 16 kg P2O5/ha through PROM and 32 kg P2O5/ha through DAP. With regard to sulphur levels application of sulphur up to 30 kg/ha recorded significantly higher growth, yield attributes, yields as well net returns ( 46723) with B:C ratio 2.96 over control and 15 kg S/ha.

BACKGROUND In setting of the current COVID-19 pandemic, it is crucial to endorse infection control competencies. However, whether virtual training is equivalent to in-person teaching to develop such competencies requires further elucidation. AIM We aim to explore the effect of a brief, three-to-five-minute training session on infection control competencies in the major area of emergency department infection control, using virtual versus in-person training. METHODS Two hospitals were chosen, and the study design was a quasi-experimental multi-centre nonequivalent groups design. RESULT The learning score increased from 39.06%, SD=17.18 (95% CI 32.39-45.72) to 52.48%, SD=26.48 (95% CI 44.01-60.95) in the virtual training group, and from 47.86%, SD=22.51 (95% CI 41.47-54.26) to 79.65%, SD=21.45 (95% CI 70.14-89.16) after the in-person teaching. The mean difference between the two groups revealed a higher learning score using in-person teaching: 27.16%; t(60)=-4.12, p = 0.0001. CONCLUSION Infection control competencies are better acquired via in-person teaching than by virtual education.
