Published: November 2023

Since the ancient times herbal formulations have been used in the ailment of various diseases. The plant Ziziphus oenoplia is also known for its various pharmacological activities including wound healing property. But evaluation of the safety of the herbal formulations after application is necessary for their acceptance in the scientific community. As a result, in the current research work sub-chronic dermal toxicity of Ziziphus oenoplia extract incorporated herbal hydrogel was conducted to evaluate its safety profile upon application on the skin. Three different doses of extract loaded hydrogel (1g/kg, 2g/kg and 4g/kg body weight of animals), blank (4g/kg body weight) and control (0.9% NaCl solution) was applied on 15 adult healthy New Zealand White Rabbits in groups of 3 animals each. Application was done on the dorso-ventricular trunk of the rabbits and the animals were observed for 28 days for any clinical signs of intoxication, food consumption and change in body weight gain. After completion of the experiment no skin irritation such as erythema, edema or eschar formation was observed in all the animal groups. No signs of mortality or morbidity was seen. Food consumption was found to be normal and no drastic increase in body weight gain of the rabbits was observed in the control, blank and test groups of rabbits. From this study it was concluded that the Ziziphus oenoplia extract loaded Carbopol hydrogel was non-toxic and could be safely used as a dermal formulation.

Ongoing over-exploitation and delayed responses to environmental change highlight the urgency for action to promote vertebrate recoveries by 2030
Authors: Cornford Richard , Freeman Robin
Published: November 2023

To safeguard nature, we must understand the drivers of biodiversity loss. Time-delayed biodiversity responses to environmental changes (ecological lags) are often absent from models of biodiversity change, despite their well-documented existence. We quantify how lagged responses to climate and land-use change have influenced mammal and bird populations around the world, while incorporating effects of direct exploitation and conservation interventions. Ecological lag duration varies between drivers, vertebrate classes and body size groupings—e.g. lags linked to climate-change impacts are 13 years for small birds, rising to 40 years for larger species. Past warming and land conversion generally combine to predict population declines; however, such conditions are associated with population increases for small mammals. Positive effects of management (>+4% annually for large mammals) and protected areas (>+6% annually for large birds) on population trends contrast with the negative impact of exploitation (<−7% annually for birds), highlighting the need to promote sustainable use. Model projections suggest a future with winners (e.g. large birds) and losers (e.g. medium-sized birds), with current/recent environmental change substantially influencing abundance trends to 2050. Without urgent action, including effective conservation interventions and promoting sustainable use, ambitious targets to stop declines by 2030 may already be slipping out of reach.
What Fuels You?
Authors: Bakke Gretchen
Published: November 2023

Perhaps, a man name Thomas Turnbull once suggested, perverse economic models are the best way to contrive an economy not based on growth and profits. I have thought about this a lot, playfully. How might one cook up a reward structure for avoiding maxim bang for buck? How might increased efficiency become understood, systemically, as a bastardized version of human activity? How might extraction stop being a thing we do to ourselves (not to mention our planet entire)? Playfully, I took the efficiency of a solar panel (22% rather low all things considered) and turned it around and around in my head, a gobstopper of a percentage. How might that lowness become both metric and goal? What world would we live in if only 22% of our time and effort were directed toward productive work? What minor revolution might that point us toward? Not a goal of 'total this' or 'total that' but 'minor this' and 'minor that’ aimed at a slow attrition from neoliberal economics toward a blooming of a different sort. It should never be about the individual, but that is how I have written it, because to consider who one is, how one works, and what one aspires as if one were a lawnmower (or similar) is such a silly (and perfectly playful) idea.
A Politics of Solar Abundance
Authors: Daggett Cara New
Published: November 2023

The abolition of fossil fuels requires more than new fuels to power modern pleasures. It also requires new subjectivities. Petro-people need to become solar subjects. Becoming solar subjects, and not just consumers of solar energy, means nurturing solarity as a way of life, a geo-theology. Theology might seem an odd emphasis for energy studies, but fossil fuels have a strong cosmological dimension that helps explain their grip on modern publics. The fossil sacred is capitalist work – that which moves matter to make a profit – in a presumed world of scarcity and struggle. The fossil evil is waste. Solarity is well-suited as a counter-theology to fossil fuels, as the sun neatly reverses fossil values. The sun is sinful according to fossil theology, offering itself abundantly with no concern for efficiency. As a political strategy, solar abundance – and not reduction – is also best equipped to counter the pleasures of fossil-fueled life. The ascetic approach to energy finds morality in foregoing energy expenditure, while solar abundance encourages better spending and giving. Both involve limits, but in worlds of abundance, the goal is to limit dangerous accumulation, and to appreciate how cooperative spending and sharing can generate more well-being.

The Literacy Component Model: A Pragmatic Universal Paradigm
Authors: Knight Bruce Allen , Galletly Susan , Aprile Kerry Therese
Published: November 2023

The Simple View of Reading (SVR; Gough & Tunmer, 1986; Hoover & Gough, 1990), a well-established model used widely in reading research, states that reading comprehension builds from two relatively independent subskills, word-reading skills and language skills. By not including writing and key literacy-processing skills, the SVR lacks power as a universal model to guide instruction. This article proposes the Literacy Component Model (LCM) that the authors have adapted by including writing with the SVR to highlight five key literacy components, namely: reading comprehension, word reading, language skills for literacy, word writing, and written expression. Additionally, it includes phonological, orthographic, visual, and automatising subskills of word reading and word writing, as important impacting factors. Already used successfully with practitioners, the LCM is a flexible pragmatic paradigm supporting an understanding of literacy development across different orthographies.

Published: November 2023

Contexto: A Cartografia Escolar tem se mostrado uma importante metodologia no processo de ensino e aprendizagem. Nesse sentido, os mapas mentais compreendidos como uma linguagem, contribuem para a formação crítica dos alunos, possibilitando a leitura e análise espacial. Nessa perspectiva, a presente proposta teve como objetivo, investigar a partir do processo de ensino e aprendizagem em Geografia como a cartografia pode, por meio das diferentes formas de construção e representação do conhecimento geográfico, promover a desacomodação e a autonomia do educando da Educação de Jovens e Adultos (EJA). Metodologicamente, nos embasamos nas leituras com o foco na geografia escolar, a partir dos conceitos geográficos e na Teoria Histórico-Cultural de Vygotsky. Buscamos suporte na metodologia de Kozel (2009) e Lynch (1997) para a análise e interpretação dos mapas mentais. A intervenção a partir do diálogo, foi realizada com alunos da EJA, etapas do ensino fundamental, de uma escola municipal de Pelotas-RS. Como resultado, com base nos conceitos de paisagem e lugar, pode-se perceber que os alunos ao se familiarizarem com a elaboração dos mapas mentais, compartilharam saberes, conhecimentos e experiências, trazidos da sua cotidianidade. O trajeto casa-escola foi o foco de observação e registro para fins de representação. Na sequência, foi possível elaborar o mapa colaborativo/participativo de forma coletiva, notando-se a presença diversificada de simbologias e grafias que expressavam as vivências dos alunos. Destaca-se que a metodologia atribuída para a análise dos mapas mentais, articulado aos conceitos geográficos, possibilitou maior interação e autonomia do aluno no processo de ensino e aprendizagem.

O objetivo foi avaliar o efeito da suplementação oral de probiótico, prebiótico e simbiótico no tecido muscular esquelético, gastrocnêmio, de ratos expostos ao tabagismo, através da dimensão fractal (DF). Sessenta e quatro ratos foram aleatoriamente alocados em 8 grupos (n=8): com ração controle (C) ou suplementadas com probiótico (Pro), prebiótico (Pre) ou simbiótico (Simb) e os quatro grupos foram alimentados com as rações C, Pro, Pre e Simb e expostos ao tabagismo. Após 180 dias de experimento, os animais foram anestesiados, sacrificados e os músculos gastrocnêmios foram submetidos a procedimento histológico de rotina e corados pela técnica de HE. As imagens dos cortes histológicos foram capturadas e submetidas à análise da DF. Os dados foram submetidos à análise de variância, seguida do teste de Tukey. Os resultados revelaram que a suplementação de probiótico, prebiótico e simbióticos atenuaram os efeitos deletérios da exposição crônica a fumaça do cigarro (p<0,05). Os resultados permitem concluir que a suplementação de probiótico, prebiótico e simbiótico atenuam os efeitos deletérios da exposição crônica e passiva a fumaça do cigarro em ratos machos jovens, como modelo pré-clínico.

Nas zonas tropicais, as práticas agrícolas estão intimamente ligadas à estação chuvosa. Em culturas de ciclo anual como a soja, semeadas e colhidas durante este período, a produção enfrenta desafios relacionados as estiagens durante o cultivo, os veranicos. Diante disso, objetivou-se analisar a influência do veranico na demanda hídrica da soja cultivada na safra de verão. O estudo foi conduzido na Fazenda Alegria, em Silvânia/GO, numa área de 66 hectares, irrigada por pivô central. As avaliações foram referentes aos anos agrícolas 2016/17, 2017/18 e 2018/19. Inicialmente foram coletadas amostras de solo na área para as análises físico-hídricas. As variáveis meteorológicas coletadas diariamente do SISDAGRO/INMET. Essas informações foram utilizadas para a elaboração do balanço hídrico do solo e verificar se haveria necessidade de irrigação complementar. Os veranicos foram categorizados com base na sua extensão temporal. Verificou-se que o consumo total de água ao longo do ciclo da soja para as três safras foi inferior ao total de precipitação pluviométrica. Foram registrados 22 veranicos. De acordo com o balanço hídrico no solo e a classificação do veranico, não haveria necessidade de irrigação complementar nas três safras avaliadas.

Published: November 2023

Rabbit farming in Brazil is growing due to the quality of meat, ease of management, high prolificacy, and their use in research and as pets. However, studies on diagnostic imaging in rabbits are scarce. This study investigated the use of ultrasonography to assess abdominal organs and blood flow in 15 male rabbits, separated by weight. The results highlighted the uniform texture of the liver, which showed lower echogenicity than the right renal cortex, a hyperechoic wall of the gallbladder, and a fusiform shape of the spleen. Parameters such as size and location of the kidneys, bladder wall thickness, and adrenal gland measurements were evaluated. Doppler was used to analyze the aorta and renal artery, calculating Doppler velocity indices to assess hemodynamic function. This study contributes to understanding abdominal ultrasonography in rabbits, providing relevant information about the anatomy and hemodynamics of these organs.

One of the efforts to reduce morbidity and mortality in children is by administering immunizations. Immunization is an effective and efficient strategy in improving national health status by preventing six deadly diseases, namely: tuberculosis, diphtheria, pertussis, measles, tetanus and polio. Counseling about the importance of immunization is an effort to increase knowledge about the importance of basic immunization for infants, so that it can reduce mothers' anxiety and fear about follow-up events after immunization which is the reason for mothers not to give immunizations. The method used is in the form of providing counseling materials on the importance of basic immunization for infants. This program will be implemented in March 2023 in toddlers in the Working Area of the Pasir Putih Public Health Center. The purpose of this community service is to provide education and provide immunizations for babies and toddlers. This activity is expected to increase knowledge and awareness of mothers about the importance of immunizing infants and toddlers.

Целью исследований являлась оценка эффективности применения листовых подкормок водорастворимыми удобрениями Aqualis и предпосевного внесения удобрения Avrora на масличном льне в условиях Центрального Нечерноземья. В различных погодных условиях 2020–2022 годов отмечена высокая эффективность применения минеральных удобрений (Азофоска и Avrora) в предпосевное их внесение и листовых подкормок водорастворимыми удобрениями Aqualis состава Марка 1 (6:14:35+ 2 MgO + МЭ) и Марка 2 (18:18:18 + 3 MgO + МЭ). Наибольшая урожайность семян масличного льна получена при двукратном применении Aqualis Марки 2 в фазу «елочка» и быстрый рост – 15,8 ц/га (27% к контролю) на сорте ЛМ 98 и 21,2 ц/га (35,8%) на сорте Исток. В засушливых условиях эффективность применения Aqualis Марки 2 при однократном применении в фазу «елочка» была высокой 1,2 ц/га семян по отношению к фону применения минерального удобрения Avrora. Увеличение урожайности льносемян при применении листовых подкормок произошло за счет увеличения количества коробочек на растении (от 2 до 4 шт.), семян в коробочке (на 1 шт.). Применение минеральных удобрений Avrora и Азофоска, в выравненной дозе по азоту 28 кг д.в./га было эффективно и обеспечило прибавку урожайности семян в среднем 3,6 ц /га.

The aim of the research was to evaluate the effectiveness of foliar application of Aqualis water-soluble fertilizers and pre-sowing application of Avrora fertilizer on oil flax in the conditions of the Central NonChernozem region. In various weather conditions in 2020-2022, the high efficiency of the use of mineral fertilizers in their pre-sowing application and foliar fertilizing with Aqualis water-soluble fertilizers (Azofoska and Avrora) was noted. The highest yield of oil flax seeds was obtained with the double application of Grade 1(6:14:35+ 2 MgO + МЭ) and Grade 2 (18:18:18 + 2 MgO + МЭ) in the “herringbone” phase and budding phase - 15.8 c/ha (27% of the control) on the LM 98 variety and 21.2 c/ha (35.8%) on the variety Istok. In arid conditions, the efficiency of applying Aqualis Grade 2 (18:18:18) with a single application in the herringbone phase was high 1.2 c/ha in relation to the background of application of the mineral fertilizer Avrora. The increase in the yield of flax seeds when using leaf fertilizing occurred due to an increase in the number of boxes on the plant (from 2 to 4 pcs.), seeds in a box (by 1 pc.). The use of mineral fertilizers Avrora and Azofoska, at an equalized nitrogen dose of 28 kg a.i./ha, was effective and provided an increase in seed yield on average 3.6 c/ha.

Authors: Chen Bingbing , Li Bing , Hu Zhenlong
Published: November 2023

A library is an institution that collects and organizes book materials for people to read and reference. The design of this system is aimed at information-based management of the library's borrowing function, enabling it to achieve the practical goal of improving the work efficiency of administrators. The book borrowing management system in this article adopts a B/S architecture, PHP language, and MySQL database. The administrator of this system can manage the library's book information, reader information, and borrowing and returning information; Readers and users can query book information, modify personal information, and report the loss of their own documents. Unlike general book borrowing management systems, this system uses intelligent recommendation algorithms to recommend books to readers based on their borrowing records. The article provides a detailed introduction to the technical architecture used in the development of the system, as well as a description of various functions of the system.

In daily life, distance measurement is everywhere. In order to accurately measure the distance information of the target object, a system design for binocular ranging based on FPGA is proposed. The internal and external parameters of the binocular camera are determined through the Zhang Zhengyou calibration method (two-dimensional target), and then the basic model of the binocular camera is derived. The data model of the binocular camera is derived based on the binocular camera model. The calibrated binocular camera parameters are used to perform binocular correction and distortion correction on the image data collected by the binocular camera. The corrected left and right eye views are matched with pixel points through a stereo matching algorithm to form a disparity map. The principle of triangle similarity is used to estimate the target distance and obtain the coordinate system of the target. Finally, the data is measured by deploying it on the FPGA development board.

The design process of steam generators is complex and involves a significant workload for analysis and design. To streamline this process, we have developed stress calculation software for key parts of the steam generator. The software utilizes a combination of the Qt (C++) programming language and parametric design language (APDL). By automatically generating the APDL command flow file, the software calls ANSYS for background operations and displays the results in a cloud diagram. This approach simplifies the design process and ensures accuracy in stress calculations. The tool allows users to input relevant parameters and obtain accurate calculation results, greatly reducing the complexity of ANSYS usage and enhancing design efficiency.
Utilizing MOSFET - Based Buck - Boost Converter to Ensure the Operation of New Energy Vehicle Battery System at Low Temperature
Authors: Wang Borui
Published: November 2023

This article proposes a MOSFET-based buck-boost DC/DC converter solution to the problem of battery output voltage drop in low-temperature environments for electric vehicles. At low temperatures, the chemical reaction rate of the battery slows down, resulting in a drop in output voltage, which cannot provide a stable voltage for the drive system. To solve this problem, it is proposed to add a buck-boost DC/DC converter between the positive and negative poles of the battery, and use the high-speed switching characteristics of MOSFET to adjust the battery output voltage in real time through duty cycle control. When the temperature is too low, increase the duty cycle to obtain a higher output voltage, and provide a stable working voltage for the drive motor through inversion. At the same time, the output of the converter can also be used for battery power to achieve self-heating, helping the battery quickly return to normal operating temperature.

Authors: Zhou Zhaoming , Chen Yukun
Published: November 2023

The performance of rotary control head or rotary blowout preventer will directly affect the success or failure of the underbalanced construction of oil and gas well. Once the failure occurs in the construction process, there may be blowout and other big drilling accidents. Based on the Yeoh constitutive equation, the dynamic sealing model of rubber core is established in this paper, and the sealing process of rubber core during tripping and tripping is calculated and analyzed. Then, the effect of the bubble defect in the core on the sealing performance of the core under different drilling fluid pressure was analyzed. Finally, the effect of metal degumming on the sealing performance of the core was analyzed. The results showed that the larger the initial sealing pressure and contact stress value of the Mises core was, the better the sealing effect of the Mises core was, while the larger the Mises stress value was, the more likely the Mises core was to suffer fatigue failure. The drilling fluid pressure significantly affects the maximum equivalent stress of the core, and the maximum equivalent stress appears in the bubble position inside the core at different times and under different drilling fluid pressure. The degumming position is placed in the contact position between metal and rubber core. When the tensile stress exceeds the limit of rubber core material, radial and circumferential cracks will occur on the upper surface of rubber core. With the increase of drilling times, rubber is prone to fatigue cracks, which eventually lead to mutual tearing.

Published: November 2023

In order to ascertain the difference in the improvement effects of the two modes of water storage and drainage on saline-alkali soil. The method of simulating test plots was adopted to establish a closed water storage test area and an opened drainage test area. The interannual dynamic characteristics of soil salinity at different levels are analyzed. [Results] Under the water storage mode and drainage mode, the salt content of 0-100 cm soil was in a downward leaching migration state. Under the water storage mode and drainage mode, the soil salinity of each layer showed a trend of first decreasing and then increasing from 2015 to 2019. The horizontal migration of soil salinity in the water storage mode is mainly the interannual circular migration from the far end of the pool to the end of the near pool and then to the end of the far pool. The horizontal movement of soil salt in drainage mode is mainly one-way movement from the far end of the pool to the near end of the pool.

In recent years, with the rapid development of drone technology, unmanned aerial systems have been widely applied in various fields. Although the flight control and airframe structure of traditional multirotor aircraft are fairly mature, they still face challenges such as low aerodynamic efficiency, low safety, and complex structure. In order to solve these issues, a dual-tiltable-ducted-fan aircraft system is designed. The system is equipped with an STM32F407 processor as the main controller, which receives motion control information from the remote control module. By employing cross-coupling network control methods, it coordinates the output values and tilt angles of the two channeling fans to achieve stable control of the aircraft's flight attitude.
