Cellulose is a natural polymer formed by chains of polysaccharide carbohydrates. Traditional processes for extraction of cellulose are expensive and require solvents with high ionic strength and stringent conditions. In this paper, we propose the extraction of cellulose from Bougainvillea spectabilis by using a traditional procedure, such as alkaline and acidic hydrolysis extraction, as well as the Vieira extraction method with the aid of two ionic liquids (ILs), with the purpose of using a solvent that allows reducing the harmful impact on the environment and human health. The obtained fibrous materials were analyzed by FTIR spectroscopy and the gravimetric method. According to gravimetric measurements, the results show an efficiency of 99.3% for the proposed extraction method and of 42.97% for acid hydrolysis. These results show that the proposed method allows adequate extraction using ionic solvents.

Published: March 2021

In this study, hydrogels based on poly(vinylpyrrolidone) and chitosan, derived from different mixing ratios of poly(vinylpyrrolidone)/chitosan, were synthesized by the freeze-drying technique with the aim of obtaining new systems that could be used to release tetracycline hydrochloride (TH). Freeze-drying methods were also used to prepare the hydrogels containing TH. The hydrogels were characterized using Fourier transform infrared spectroscopy and scanning electron microscopy, as well as in terms of dynamic water vapour sorption capacity. The poly(vinylpyrrolidone)/chitosan hydrogels were evaluated with regard to the release of TH. The release profiles of TH from the poly(vinylpyrrolidone)/chitosan hydrogels depended on the chitosan content. It could be seen that if the concentration of chitosan was too high, the release was delayed and not fully achieved, because the release of the drug was prevented by the crystalline areas of the chitosan. According to the release study, the drug release mechanism of the poly(vinylpyrrolidone)/chitosan hydrogels loaded with TH perfectly fitted the Higuchi and the Korsmeyer-Peppas models. The highest value of water vapor sorption capacity was obtained for the hydrogel with the poly(vinylpyrrolidone)/chitosan ratio of 50/50. PVP-CS loaded with 3 wt% TH may potentially be used for the controlled delivery of tetracycline to treat oral infections.

Published: March 2021

Three novel biologically active quaternized sodium alginates were synthesized via the reaction of sodium alginate (SA) with 3-chloro-2-hydroxypropyl trimethylammonium chloride, at room temperature for different time intervals (1, 3 and 6 h), to produce quaternized sodium alginates designated as QSA1, QSA3 and QSA6. The percentage degree of quaternization (DQ%) significantly increased with increasing the reaction time. Images from FTIR, 1H-NMR, XRD and SEM have confirmed the chemical structures of the QSA samples. Their antimicrobial activity was investigated against bacteria and fungi using XTT assay, and the results showed that all QSA samples displayed high growth inhibition capacity of the tested microorganisms, compared to zero inhibition for SA, as shown by their lower minimum inhibitory concentration (MIC). The QSA6 was the best antimicrobial composite, displaying the same MIC value as that of the used reference drugs. The developed composites were found to be safe on normal human fibroblast cells (WI-38 cell line), by evaluating them using cytotoxic activity measurement, which makes QSA a promising material in biomedical and food applications.

Authors: Nakamura Tomoya , Asami Takuya , Miura Hikaru
Published: March 2021

Recently, there has been research into drying by applying an ultrasonic vibrator directly to wet clothes. However, this method may damage the fabric and decorations of clothing because the ultrasonic vibrator is in direct contact with the wet clothing. Therefore, we would like to dry wet clothes without contact using an aerial intense ultrasonic wave. In this paper, an intense standing wave sound field was formed in the air using two sets of transverse vibrating plate type ultrasonic sound sources, and a cloth larger than the wavelength of the sound wave in the ultrasound field was dried. We compared the moisture content on dry basis, drying rate, and drying time of the drying samples, and determined the differences in drying effect depending on differences in the installation position of the drying samples in the ultrasound field.

Thickness scaling on ferroelectric properties of sputter-deposited poling-free Al0.78Sc0.22N films has been examined. The c-axis oriented films were confirmed by X-ray rocking curve measurements with a film as thin as 10 nm. Ferroelectric-type hysteresis and poling-free behaviors are observed from the capacitance measurements, even with a thickness of 20 nm. The remnant polarization (P
r) shows a gradual degradation when the thickness is less than 35 nm. The switching (SW) cycle test reveals a wake-up effect for the film, especially for thick films of over 35 nm. A longer SW cycle of over 105 times can be obtained with thinner Al0.78Sc0.22N films around 20 nm at the cost of P
r.

Desde la época Colonial hasta la actualidad, América Latina ha sido fuente de materias primas para los países industrializados, situación que le ha colocado en un lugar específico del sistema-mundo moderno (Walerstein, 2004). De acuerdo con la teoría de Walerstein,el actual orden mundial, capitalista, surgió en el siglo XVI en Europa y América, expandiéndose posteriormente al resto del planeta. En lo político, dicho sistema-mundo no surgió con una estructura política unitaria, sino como un sistema interestatal conectado a través del intercambio de bienes básicos, capital y trabajo.

Hay que asegurar la postura epistemológica de la línea de análisis de medios desde lo que se ha llamado hegemonías discursivas. No necesariamente hay que meterse de lleno en el cuento de lo instru-mental, cuantificable, aunque sirven métodos tales, sino que hay que pensar que es necesaria una fundamentación en la construcción de conocimiento que se relaciona con la experiencia humana, dado esto en la racionalización discursiva misma. Así, la lógica y el método conducen a analizar el lenguaje de medios y la acción en los medios.

Para lograr manejarlas adecuadamente las crisis, primero es necesario entender qué son y cuáles son sus principales características. Existe una gran cantidad de literatura al respecto y no es posible asignarle una sola definición al término. Si se analiza la teoría de la crisis, lo más factible es encontrar cuatro corrientes depensamiento. La primera se refiere a la crisis solamente como una amenaza, la segunda define el concepto como un periodo de interrupción, la tercera combina las visiones de amenaza e interrupción y la cuarta presenta las dos caras de una crisis. La negativa está asociada con el peligro que representan este tipo de fenómenos y la positiva con las nuevas oportunidades de cambio que éstos propician.

Background: Misoprostol is a widely popularly used drug in treatment of missed abortions. It is very simple to use, easily available and has an
average efciency greater than 90%. Adrug this popular and versatile needs better study to improve its efciency and minimize all possible adverse
unwanted effects. Hence the idea to make a comparative study between the different modes of administration of Misoprostol was arrived upon so as
to understand it in a much better way. Aim: A comparison of the efcacy of Misoprostol used in sublingual, oral and vaginal routes for missed
abortion. Material and methods: The study was conducted at the Department of Obstetrics and Gynaecology in Nilratan Sircar Medical College
and Hospital, Kolkata after approval by the ethical committee. The sample size was 100 women being treated for missed abortions where
prospective sampling was carried out to determine the candidates to be selected for the study. Single centred, institution based, randomized
controlled trial. Cases included in this study were divided into 3 groups: Sublingual Group, Oral Group and Vaginal Group. Result: It was found
that in oral, 4(11.8%) patients had fever. In sublingual, 6(17.6%) patients had fever. In vaginal, 2(5.9%) patients had fever. Association of fever vs.
group was not statistically signicant (p=0.3220). Conclusion: The study demonstrates that both vaginal and sublingual misoprostol have similar

Современные способы использования хмелепродуктов в пивоварении
Authors: Грибкова Ирина Николаевна , Гернет Марина Васильевна
Published: March 2021

Статья посвящена исследованию мировых тенденций в области использования хмеля с различными органолептическими и физико-химическими свойствами, а также продуктов переработки хмеля, что актуально вследствие отсутствия подобного опыта в отечественной отрасли. Представленное аналитическое исследование преследовало цель теоретически обосновать и осуществить поиск основных направлений в развитии технологии переработки хмелепродуктов, а также выявить достоинства и недостатки при использовании в пивоварении. Анализ изученных научных данных показал, что в отрасли применяются различные виды хмеля – начиная с генномодифицированных с различными уровнями ароматических и горьких веществ, так и различными фруктовыми, цветочными и травяными ароматами, что расширяет ассортимент выпускаемой пивоваренной продукции.  Выявлено множество патентов, связанных с технологией изомеризованных экстрактов, а также иных продуктов переработки хмеля и его отходов. Основное заключение, которое последовало за анализом выявленной научной литературы, это то, что инновационные разработки различных стран мира, в основном, США и Европы, направлены на получение растворимых экстрактов, обогащенных определенным соединением, которое обеднено по составу по сравнению с хмелем и требует внесения дополнительных продуктов переработки хмеля. С другой стороны, исследователи пытаются сократить потери от утилизации хмелевой дробины и используют ее для извлечения полезных соединений, которые в ней остались после использования.  Основным выводом представляемого аналитического обзора является необходимость грамотного сочетания в применении традиционного хмеля и новых видов сырья, представленных на рынке пивоваренной отрасли.

Published: March 2021

Общемировая тенденция внедрения «зеленых технологий» может найти успешное межотраслевое применение в сельском хозяйстве, медицине, пищевой промышленности и  спортивном питании в результате развития технологий получения индивидуальных соединений природного происхождения. Расширение и углубление фармакологических исследований каротиноидов определило возобновление более детального интереса к межотраслевому изучению этих соединений. Полиеновая цепь детерминирует совокупное биологическое действие каротиноидов и их основные физико-химические свойства. Вместе с тем этот структурный фрагмент способствует их активному окислению и изомеризации в процессе получения, очистки и хранения. Решение вопроса стабилизации субстанций индивидуальных каротиноидов расширит возможности их использования.  Микрокапсулирование является перспективным методом стабилизации данного класса соединений. В связи с этим поиск инструмента эффективного и рационального исследования процесса микрокапсулирования является актуальным научным направлением. Нотация IDEF0 представляет собой вариант моделирования функциональных систем, в частности, производственной. Главным ее преимуществом является логическая визуализация процесса, что обеспечивается применением графического языка иерархии диаграмм и может быть использовано для построения модели стабилизации каротиноидов.
Цель исследования – микрокапсулирование каротиноидов и построение соответствующей модели стабилизация в нотации IDEF0.
Логическое структурирование стабилизации каротиноидов проводилось в обозначениях IDEF0. Микрокапсулы с каротиноидами ликопином, лютеином, β-каротином и астаксантином получали путем простой коацервации, экструзии без нагревания и диспергирования в несмешивающейся жидкости. Анализ микрокапсул осуществлен методом спектрофотометрии. 
Нотация IDEF0 впервые применена для построения модели стабилизации субстанций, в частности каротиноидов. Правильность разработанной модели подтверждена экспериментально: по данным, полученным в соответствии с предложенной IDEF0 моделью, наиболее эффективным для микрокапсулирования каротиноидов признано диспергирование в несмешивающейся жидкости; стабильность всех четырех микрокапсулированных субстанций каротиноидов составила два года.

Для каждого из двух рециркуляционных контуров выполнен эксергетический анализ. Полученные с минимальными энергетическими затратами кормовые пелле-ты из шрота семян рапса соответствуют требованиям ГОСТ 23513-79. Пред-лагаемая технология позволяет снизить удельные энергозатраты на 12-15 %, повысить экологическую безопасность на всех этапах технологического процесса, максимально снизить выброс отработанных теплоносителей в окружающую атмосферу.
Lo sviluppo delle discipline
Authors: Orefice Paolo
Published: March 2021

The birth and development of disciplines, as organized knowledge that guides the interpretation of reality, are inscribed in the heritage of the knowledge of our species. These follow the triple regulating principles of the historical flux of the meanings of feeling and thinking: cognitive potential, mental processing, intangible and tangible products. The flow from the indistinct feeling of the origins evolves through the archaic forms of the magic thought; to the ancient forms of declarative thought up to the modern forms of demonstrative thought. The latter with the separation between disciplines does not recognize the interconnection inherent in reality, loses the scientific revolution character and generates the unsustainable human development on the planet. From the global interconnection experience of the contemporary world, a new paradigm comes to life: transdisciplinarity, whose epistemology recomposes the knowledge and reality’s unity and diversity beyond the barriers between disciplines.
La presencia de la metafísica fichteana en Esteban Echeverría y José Mármol
Authors: Scarfia Lucas Damián
Published: March 2021

El presente trabajo plantea como hipótesis que la fuente de influencia más profunda en el pensamiento romántico argentino no fue el romanticismo francés sino el idealismo y el romanticismo alemán. Se trata de demostrar el influjo de la metafísica del anhelo, que Fichte expone en la Grundlage der gesamten Wissenschaftslehre (1794-1795), en dos obras: El peregrinaje de Gualpo (ca. 1825) de Esteban Echeverría y los Cantos del peregrino (1846) de José Mármol. De esta manera se muestra el modo en que uno y otro de los autores caracterizan la figura del peregrino como personaje principal y alter ego en sus textos. A su vez, se resaltan las nociones de melancolía y de hastío como enclaves que conforman el pensamiento idealista y romántico. En este sentido se muestra que tanto Fichte como los Frühromantiker y los intelectuales argentinos, forman parte de una corriente de pensamiento idealista y romántico que cabe calificar como melancólico, práctico y moral.

Authors: Shakya Subarna , P P Joby
Published: March 2021

Wireless Body Sensor Network (BSNs) are devices that can be worn by human beings. They have sensors with transmission, computation, storage and varying sensing qualities. When there are multiple devices to obtain data from, it is necessary to merge these data to avoid errors from being transmitted, resulting in a high quality fused data. In this proposed work, we have designed a data fusion approach with the help of data obtained from the BSNs, using Fog computing. Everyday activities are gathered in the form of data using an array of sensors which are then merged together to form high quality data. The data so obtained is then given as the input to ensemble classifier to predict heart-related diseases at an early stage. Using a fog computing environment, the data collector is established and the computation process is done with a decentralised system. A final output is produced on combining the result of the nodes using the fog computing database. A novel kernel random data collector is used for classification purpose to result in an improved quality. Experimental analysis indicates an accuracy of 96% where the depth is about 10 with an estimator count of 45 along with 7 features parameters considered.

The aim of this investigation was to explore the neuroprotective and memory-enhancing effect of Hibiscus sabdariffa L. ethanolic extract on scopolamine-induced learning and memory deficit in young mice. The nootropic and neuroprotective potential of the extract in scopolamine induced amnesic mice was evaluated by elevated plus maze, step-down avoidance, and Morris water maze tests after 14 days of daily administration. The extract significantly enhanced learning, memory function, improved spatial recognition, as well as successfully reversed scopolamine-induced amnesia. Also, it significantly decreased the brain acetylcholinesterase activity and optimized brain catecholamine levels. Histopathological results confirmed the protective effect of the extract on hippocampal and cortical neurons. These findings suggest that ethanolic extract of H. sabdariffa can confer neuroprotection and augment memory. In conclusion, H. sabdariffa can be used in the management of amnesia and neurodegenerative diseases involving learning, memory, and cognitive dysfunctions.

Published: March 2021

The agriculture wastes are considered as a big environmental problem. The main purpose of this research is to determine the possibility of producing fired clay bricks from a mixture of agriculture wastes in addition to other wastes. The first type of wastes is the cullet while the second type is the wastes is the waste clay bricks (Homra) and the third is an agricultural residue obtained from wheat and sugarcane cultivation. The first step of the experimental work is performing XRF and sieve analysis for raw materials. Brick samples with Cubic shape with dimensions 50 × 50 × 50 mm3 were formed by 1 MPa dry pressing then drying at 120 oC overnight. Tile samples were fired at temperatures of 850 oC for 15 min soaking time. Water absorption, apparent porosity, and mechanical properties were determined and compared to ES 4763 / 2006 and ASTM C 62 / 2013 standards. According to the previous experimental work, it was found that the samples that has a composition (38 % Desert clay, 20% Homra, 10% cullet, 15% Wheat ash straw, 17% sugarcane) has the optimum properties with respect to ES 4763 / 2006 and ASTM C 62 / 2013 standards.

Published: March 2021

The purpose of this research is to conduct aerodynamics study and design a hybrid drone system of fixed-wing and multi-copter. The mission of this drone is to measure human body temperature during COVID19 pandemic. The specific aim of the drone is to fly and cover larger industrial areas roughly about 50 km2 with longer flying time than the conventional drone, of about 1.5 hours. The applications of the simulation software such as XFLR5 and ANSYS have a big impact in identifying areas that need to be improved for the drone system. XFLR5 software was used to compare the characteristics of different airfoils with highest lift over drag, L/D ratio. Based on the airfoil selection, it was found that NACA 4412 airfoil produces the highest L/D ratio. The detailed geometry of the drone system includes a fuselage length of 1.9 meters and wingspan of 2 meters. Moreover, 10 sheets of solar panels were placed along the wing for sustainable flight operation to cover wider areas of mission. The structural analysis was done on ANSYS to test the elastic stress, equivalent strain, deformation, factor of safety pressure as well as lift and drag forces under various operational conditions and payloads. The landing gear was analyzed for harsh landing. ANSYS Computational Fluid Dynamics (CFD) was utilized to study the aerodynamics of the drone at different parameters such as the velocities and angles of attack during the operation. This design ensures the stability of the drone during the temperature measurement phase. The best thermal-imaging camera for such purpose would be the Vue Pro R 336, 45° radiometric drone thermal camera with a resolution of 640 x 512 pixels. This camera has the advantage of a permanent continuous out focus that give the ability of taking measurements even if there was changing on the altitude or any kind of vibrations.
