Важной задачей современной органической химии является открытие новых, ранее не известных науке веществ, которые могли бы расширить область наших знаний и пополнить номенклатуру высокоэнергетических или биологически активных продуктов. 3,7,10-Триоксо-2,4,6,8,9,11-гексааза[3.3.3|пропеллан и его нитропроизводные являются новейшими продуктами класса гетероциклов, их азотсодержащая полициклическая структура предполагает наличие интересных и полезных свойств, что обусловливает проявленный интерес к данной работе. Химия 3,7,10-триоксо-2,4,6,8,9,11-гексааза[3.3.3|пропеллана малоизучена и представлена лишь двумя алкилпроизводными и теоретическими расчетами энергетических характеристик нитропроизводных. В статье преставлены результаты исследования нитрования 3,7,10-триоксо-2,4,6,8,9,11-гексааза[3.3.3]пропеллана (THAP) концентрированнойазотной кислотой. Установлено, что в процессе нитрования наблюдается протекание двух конкурирующих реакций – лактам-лактимной перегруппировки и нитрования. Было показано, что продукты реакции сильно зависят от температуры реакционной массы. Установлено, что температуре -40 ºС протекает образование лактимной формы ТНАР, тогда как при постепенном увеличении температуры сначала образуется мононитропроизводное пропеллана, а при температуре 40 ºС идёт селективное образование 3,7,10-триоксо-2,6-динитро-2,4,6,8,9,11-гексааза[3.3.3]пропеллана с выходом 30%.
An important task of modern organic chemistry is the discovery of new substances previously unknown to science, which could expand the area of our knowledge and replenish the range of high-energy or biologically active products. 3,7,10-Trioxo-2,4,6,8,9,11-hexaaza[3.3.3]propellane and its nitro derivatives are the newest products of the class of heterocycles; interest in this work. The chemistry of 3,7,10-trioxo-2,4,6,8,9,11-hexaaza[3.3.3]propellane is poorly understood and is represented by only two alkyl derivatives and theoretical calculations of the energy characteristics of nitro derivatives. The article presents the results of a study of the nitration of 3,7,10-trioxo-2,4,6,8,9,11-hexaaza[3.3.3]propellane (THAP) with concentrated nitric acid. It was found that in the process of nitration, there are two competing reactions - lactam-lactam rearrangement and nitration. It was shown that the reaction products strongly depend on the temperature of the reaction mixture. It was found that at a temperature of -40 ºС the formation of the lactimic form of THAP proceeds, whereas with a gradual increase in temperature, a mononitro derivative of propellane is first formed, and at a temperature of 40 ºС, the selective formation of 3,7,10-trioxo-2,6-dinitro-2,4,6,8,9,11-hexaaza[3.3.3]propellane in 30% yield.

В различных технических приложениях применяются рабочие среды типа суспензий, которые при достаточно высокой концентрации частиц твердой фазы демонстрируют аномалии вязкости. Существо этих аномалий заключается в том, что при приближении скорости сдвига к некоторому пороговому значению наблюдается явление резкого возрастания вязкости жидкости. При этом в соответствующих зонах течения рабочая среда начинает вести себя подобно твердому телу. Механическое поведение такой рабочей среды может быть описано в рамках реологической модели вязкопластической жидкости, которая позволяет учитывать проявление эффекта“упрочнения” или “отвердевания”. Рассмотрена методика определения параметров такой реологической модели на основе обработки экспериментальных данных зависимости касательного напряжения от скорости сдвига. Предложен алгоритм для реализации этой методики.
In various technical applications, working media such as suspensions are used, which, at a sufficiently high concentration of solid phase particles, demonstrate viscosity anomalies. The essence of these anomalies lies in the fact that when the shear rate approaches a certain threshold value, the phenomenon of a sharp increase in the viscosity of the liquid is observed. At the same time, in the corresponding flow zones, the working medium begins to behave like a solid. The mechanical behavior of such a working medium can be described within the framework of a rheological model of a viscoplastic fluid, which allows for the manifestation of the effect of “hardening” or “solidification”. The method of determining the parameters of such a rheological model based on the processing of experimental data on the dependence of the shear stress on the shear rate is considered. An algorithm for the implementation of this technique is proposed

In the fish pond ecosystem there are various factors that can inhibit fish growth or even kill fish, one of which is the water factor, the water itself has various factors, one of which is the quality of PH levels and amonia levels. Therefore, this paper discusses the design and manufacture of a control device for PH levels and amonia levels to make it easier for farmers to check PH levels and amonia levels in the pond. This control device uses a DFROBOT V.2 sensor as a PH sensor and a DS18B20 sensor as a temperature sensor as well as an Arduino UNO controller. The method used to control amonia is by comparing the data from PH and the temperature in the pool water, this tool will work if the amonia level is higher. from 0.8ppm by activating the aerator to keep the amonia in the pool water normal. Meanwhile, to maintain the PH of the water more than 6 and less than 7, it is necessary to add pond water by activating the water pump. The results of this study can be used as a reference for future research for the development of Arduino Uno-based PH and amonia level control devices.

Background: Dipylidium caninum, a zoonotic cyclophyllidean tapeworm, mainly infects dogs, cats, and occasionally humans as well. Here, we present D. caninum infection in a domestic cat. A cat of about one year of age with a history of intermittent diarrhea and shedding stool containing whitish cooked rice like soft particles. Methods: The case was identified by thorough clinical, coprological, and parasitological examinations, and treated accordingly. Results: During the physical examination, the cat was found to be infested with flea, and coprological investigation revealed the presence of gravid segments of cestodes. By preparing a permanent slide, we conducted a microscopic examination, and the cestode was confirmed as D. caninum. The cat was treated with albendazole and levamisole, which were ineffective; additionally, levamisole showed toxicity. Then, we administered niclosamide which completely cured the animal. On re-examination after a week, feces were found negative for eggs/gravid segments of any cestode. Conclusion: Niclosamide was found effective against dipylidiasis and can be treated similar infections in pets.

Beka area is situated in the Adamaoua Plateau of Cameroon in central Arica. Lavas in this area has not been studied before the present work.The volcanism of Beka is characterized by basalt, trachyte and phonolite domes and flows. The petrographic study shows that basaltic lavas have porphyritic microlitic textures. The felsic lavas indicate trachytic textures.The rocks are composed of olivine, clinopyroxene, plagioclase and irontitanium oxide minerals for the basalts; clinopyroxene, alkali feldspar (including foids), sphene and titanomagnetite for the felsic lavas. Chemical analyses show that basaltic lavas are basanites. Felsic lavas contain modal feldspathoid (nepheline in phonolites). All these lavas belong to the same series, because the felsic lavas are derived from the differentiation of basaltic lavas by fractional crystallization. They show an alkaline nature according to their geochemistry. Trace elements including Rare Earth Elements characteristics show that rocks emplaced in the Winthin Plate volcanic zone. They derived from an evolved parent magma showing a low degree of partial melting and characteristics closer to a modified and evolved primitive spinel lherzolite.

Published: November 2021

The present time of globalization, interdependence and multicultural societies has brought about both opportunities and crisis that concern all fields involved with social welfare, especially education (Portera, 2020, 2006). Within the school environment, there is a growing need for intercultural education and competences at the cognitive, emotional and relational levels, which will endow teachers and students with the abilities to operate in linguistically and culturally complex contexts (UNESCO, 2015; Portera, 2013; Deardorff, 2009). However, the concepts of ‘Intercultural Education’ and ‘Intercultural Competences’ are often misunderstood and require more precise definition. The authors review the scientific literature on the aforementioned concepts and then report the results of a study carried out by the Centre for Intercultural Study at the University of Verona (Italy) which examines how teachers who work in different types of schools define and apply the concept of ‘intercultural competences’ in their praxis. The study uses a qualitative research methodology that includes a process of ‘triangulation’. Specifically, a series of semi-structured interviews, focus groups and participant observations were conducted in order to explore teachers’ intercultural competences, especially through the analysis of critical incidents. After discussing the results, the authors outline impplications for teacher education and school praxis in intercultural perspective.

Published: November 2021

Introduction - The COVID 19 pandemic led to restrictions on the conventional ways of healthcare delivery. Telemedicine provided a viable solution that was in line with the social distancing policies imposed to minimize disease transmission. This demanded physicians adapt to new ways of healthcare delivery. We surveyed geneticists across the country to determine their experience and to ascertain if telegenetics will be a lasting change.
Materials and Methods - A 23 item standardized survey was distributed to various US-based geneticists via email and other social media platforms focusing on their experience of providing care via telemedicine.
Results - We received 69 responses from physicians across 26 states. Of these, 91% practiced in academia. 70% responded that pediatric genetics takes up more than 50% of their practice. 68% had over 50% of their practice switch to telemedicine. 77% felt they could provide adequate care via telemedicine and 94% of providers would like to continue telemedicine post-pandemic.
Conclusion - The future of telemedicine looks promising as the majority of clinicians would like to routinely use telemedicine post-pandemic. Uniform guidelines for use of telemedicine in genetics may need to be proposed by professional societies and supported by federal laws.

A Review of Industrial Crop Yield Performances on Unfavorable Soil Types
Authors: Reinhardt Jana , Hilgert Pia , Von Cossel Moritz 
Published: November 2021

Industrial crop cultivation on marginal agricultural land limits indirect land-use change effects that pose a threat to food security. This review compiles results from 91 published crop-specific field trial datasets spanning 12 relevant industrial crops and discusses their suitability for cultivation on unfavorable soil types (USTs). It was shown that the perennial species Miscanthus (Miscanthus Andersson) and reed canary grass (Phalaris arundinacea L.) performed well on USTs with both high clay and/or high sand contents. Information on stoniness (particles sizes > 2 mm), where mentioned, was limited. It was found to have only a small impact on biological yield potential, though it was not possible to assess the impact on mechanization as would be used at a commercial scale. For soils with extreme clay or sand contents, half of the crops showed moderate suitability. The large yield variations within and between crops revealed large knowledge gaps in the combined effects of crop type and agronomy on USTs. Therefore, more field trials are needed on diverse USTs in different climates with better equipment and more consistent measurements to improve the accuracy of potential yield predictions spatially and temporally. Additionally, larger trials are needed to optimize cultivation and harvesting.
