В статті розглянуто питання підвищення якості та терміну зберігання кормів за рахунок заміни в їх складі комбінації рослинних і тваринних жирів на повножирову сою шляхом її обробки методом екструзії. Обробка цим методом дозволяє досягти руйнування ферментів, які спричиняють окислення жирів та одночасно пригнітити розвиток шкідливої мікрофлори в екструдаті, що у підсумку впливає на термін зберігання корму. На основі аналізу матеріалів існуючих досліджень запропоновано два способи підвищення ефективності екструзійного методу обробки за рахунок раціонального використання теплоти, яка виділяється з частинками екструдату на виході з екструдера. У першому способі – для змішування і знезараження інших рідких компонентів при отриманні багатокомпонентних пастоподібних сумішей, у другому – для напилення порошкових компонентів на частинки екструдату, які набувають адгезійних властивостей внаслідок руйнування клітин та виділення жирів при отриманні багатокомпонентних гранульованих сумішей. Дослідження проведені на створеному експериментальному стенді з відповідними вузлами змішування змонтованими на виході з екструдера і напрацьовано пробні партії сумішей. На першому етапі дослідження експериментально підтверджено ефективність екструзії та вибраних режимів для обробки повножирової сої шляхом оцінки рівня інактивації уреази, на другому – експериментально здійснено оцінку ефективності пропонованих способів використання теплоти шляхом визначення якості жирів та мікробіологічних показників сумішей. Зокрема, результати показали помірне зростання кислотного та пероксидного числа і незначне зростання мікробіологічних показників протягом 3 місяців, а також відсутність ентеропатогенних штамів кишкової палички, токсин утворюючих анаеробів та сальмонел в усіх досліджуваних зразках. На основі одержаних результатів обґрунтовано можливість використання запропонованих способів у технологіях виробництва кормів.

Излагаются принципы формирования в глобальной компьютерной среде математически однородного алгоритмического пространства распределенных вычислений и сетецентрического управления. Обсуждаются системообразующие возможности нового пространства: бесшовная программируемость, кибербезопасность и надежность распределенных вычислений. Обосновывается необходимость построения новой элементной базы в виде массовых однокристальных сетевых компьютеров с немикропроцессорной архитектурой. После устранения фундаментальных причин разнородности открываются возможности формирования в глобальной компьютерной среде математически однородного, бесшовно программируемого и кибербезопасного алгоритмического пространства распределенных вычислений для целостного решения сильносвязных задач сетецентрического управления сколь угодно большими социотехническими системами.
The purpose of the article is to study cybersecurity in a single algorithmic space of distributed computing, taking into account the developmental features of the global computer environment. To achieve the goal of the study, the methods of generalization, analysis, and synthesis were used in the work. Fundamental problems of integration of heterogeneous global computer environment resources are singled out. The causes of heterogeneity and ways to eliminate its negative consequences are shown. As applied to distributed socio-technical systems, the basic concepts of network-centric control are defined. The principles of formation in the global computer environment of a mathematically homogeneous algorithmic space of distributed computing and network-centric control are outlined. The system-forming possibilities of the new space are discussed: seamless programmability, cybersecurity and reliability of distributed computing. The necessity of building a new element base in the form of mass single-chip network computers with a non-microprocessor architecture is substantiated. It is shown that, by eliminating the fundamental causes of heterogeneity, they open up the possibility of forming in the global computer environment a mathematically homogeneous, seamlessly programmable and cyber-safe algorithmic space of distributed computing for a holistic solution of strongly connected network-centric control problems by arbitrarily large sociotechnical systems.

Published: December 2023

To evaluate the long term outcome of Presurgical Infant Orthopaedics (PSIO) in patients with Cleft Lip and Palate (CLP). A systematic literature search was performed according to PRISMA guidelines of articles from Jan 2011 till Feb 2021, using PubMed, Cochrane database and manual searching in the institutional library. Fifteen articles which met the inclusion and exclusion criteria were ranked according to the Oxford Centre for Evidence based Medicine – Levels of Evidence. The quality assessment of selected systematic reviews was done with ROBIS tool. Studies included for meta-analysis were analyzed with Q statistic methods, I index, fixed-effects, DerSimonian-Laird Random effects and Begg-Mazumdar bias indicator. Selected fifteen articles were qualitatively assessed for various parameters on long term outcome of PSIO (minimum of 5 years), showed a positive outcome in nasolabial and pharyngeal airway parameters. Due to heterogeneity in the studies, meta-analysis was carried out for five studies in which nasolabial aesthetics parameters showed a significant improvement in PSIO group compared to control group (Q Statistic : 569.52523, P-value&#60;0.001). The PSIO in patients with CLP shows significant positive changes in nasolabial aesthetics and pharyngeal airway on a long term. These results should be considered with caution as the heterogeneity of included studies cannot be denied. Hence, more controlled and well conducted studies should be performed, focussing on the individual parameters for long term outcome of PSIO.

To compare the Artificial Intelligence based model & conventional technique for prediction of extraction in orthodontic treatment plan. A comparative study was conducted on total 700 patients, who were divided into training set and testing set based on simple random sampling by means of computer generated random numbers. The photographs of the 630 patients [training set] along with the treatment plan finalized for them based on Arch Perimeter & Carey’s Analysis, was fed in the AI model [convolutional neural network (ResNet-50)] in order to train it for the stipulated function of eventually predicting the treatment plan in the testing set [70 patients], based on the input of the right profile photographs. The accuracy of measurement of the parameters of these seventy test set patients by the machine learning model relative to the manual method was compared eventually. Using the Statistical Package for Social Sciences, the acquired data was statistically analyzed, and p &#60;0.05 was deemed statistically significant. The normality of the data was examined using the Shapiro-Wilks test and the Kolmogorov-Smirnov test. Depending on the collected data and normality assessed, appropriate reliability was estimated. The analysis of 70 test patients showed that 65.12% of the total extraction cases and 62.96% of the total non-extraction cases (as predicted by the AI model) were in agreement with the results of the model analysis.It is suggested that the present AI model can further be developed in order to improve the accuracy of prediction.

Published: December 2023

The aim of the study was to analyse variations in patients’ perception on oral health, aesthetic acceptance, pain perceptions and comfort levels in patients who has undergone/undergoing orthodontic treatment by means of two types of invisible orthodontic appliances: fixed lingual metal brackets and fixed buccal aesthetic/ceramic brackets. A comparative survey to assess the patient perception after their initial levelling alignment phase was created via Google form and sent to 25 ceramic labially treated and 25 lingually treated patient. Comfort level, pain perception, speech impediment ,quality of life in patients was significantly better in Ceramic brackets as compared to lingual (p=0.001),Aesthetic perception was significantly higher impact on ceramic (p=0.001) as 72% reported no impact on aesthetics with lingual brackets as compared to 4% in the ceramic brackets. Oral hygiene maintenance: The difference on impact of Oral hygiene maintenance was statistically non- significant between ceramic brackets and lingual brackets (p=0.238).Difficulty while having food was statistically non- significantly between ceramic brackets and lingual brackets.(p=0.448). Patients prefer lingual treatment cause of their esthetic nature and their expectations are higher with lingual treatment which itself is not favorable from a clinicians perspective and it is worth noting that speech disturbances may lead to greater social embarrassment than more or less invisible ceramic brackets.

Traumatic injuries to maxillary incisors can occur at any age, but its prevalence is high among children. Earlier studies also suggested that patients with increased overjet and lip incompetence were more prone to have trauma to maxillary incisors. The effect of Traumatic dental injuries is not only physical damage but also psychological damage as aesthetic issues are involved. Measures of oral-health-related quality of life (OHRQoL) provide essential information when assessing the treatment needs of individuals and populations. A total of 300 patients with age group 11-14 years with Class II div 1 malocclsion were included in the study. Patients were further subdivider into three group depending upon the severity of maxillary incisal trauma and no trauma group, further to that the psychological evaluation of all the patients were done using short-form of the Child Perceptions Questionnaire to ascertain the impact of oral health conditions (incisal trauma) on their quality-of-life. Mean functional limitation score was lowest for group 1 and highest with group 3 with 0.46, 0.626 and 4.191.405 respectively. Mean emotional wellbeing score was lowest in group 1 and highest in group 3 with 1.381.14 and 6.101.46 respectively Overall statistically significant differences were found between three groups w.r.t oral symptoms, functional limitation, emotional wellbeing and social wellbeing with p=0.001.Traumatic dental injury to maxillary incisors is associated with significant impairment of functionality and significant psychological implications with overall CPQ index scoring being highest in patients with more severe maxillary incisor trauma.

Published: December 2023

Most of the several cephalometric analyses used for the diagnosis of sagittal dysplasia, Point A is the most widely used indicator for ascertaining of maxillary position. By the virtue of difficulty in locating point A in many cases, alternative methods had been proposed for precise location of point A but there are only few studies on the reliability of these alternative points. Point M is one such indicator for evaluating the sagittal position of maxilla. The objective of this study is to measure and compare the reliability of point A and point M.Lateral cephalogram of 50 subjects (11-20 years) were included in the study consisting of all types of skeletal malocclusions. Point A and point M were identified by two different group of orthodontists. Linear and angular measurements through both the points were analysed and compared between the observers using interclass correlation. Interclass correlation coefficient of linear and angular parameters of point M was found to be higher than point A. Point M may be considered as more reliable alternative for point A in two dimensional cephalometric analysis.
O fakcie wiary
Authors: Gębura Błażej 
Published: December 2023

Jacek Wojtysiak twierdzi, że powołując się na zachodzenie wielkiego faktu wiary, można wykazać przewagę teizmu nad ateizmem. Wobec tego poglądu formułuję trzy zarzuty: zarzut z rocznika statystycznego, zarzut z najmniejszego faktu wiary oraz zarzut z niempirycznych racji. Zarzut z rocznika statystycznego zwraca uwagę na fakt, że wielkość faktu wiary jest zawsze zrelatywizowana do momentu w czasie, w którym jest on stwierdzany. A to rodzi pytanie, na który fakt powinien powołać się teista. Zarzut z niewielkiego faktu wiary sugeruje, że w sporze między teizmem a ateizmem nie ma znaczenia, czy fakt wiary podlega pluralizacji, a więc jak wielu podmiotów dotyczy. Zarzut z nieempirycznych racji promuje pogląd, w myśl którego ustalenie empirycznych okoliczności funkcjonowania określonych religii nie zbliża teisty i ateisty do rozstrzygnięcia prowadzonego przez nich sporu.

Published: December 2023

Aiming to elucidate the costs contained in the production chain of biodiesel through microalgae, this work sought to gather several variables present in the composition of a biodiesel production industry from microalgae, entering a conjuncture of hypotheses, for the realization of mass and energy balances, as well as for the elaboration of financial analysis. Mass balances were performed, considering conversion rates, yield, reaction stoichiometry, density of compounds, among others. In the end, after all calculations, an annual production of 22.872,78 m3 of biodiesel was obtained. In the energy balance phase, the equipment containing temperature changes was taken into account to define the energy expenditure of the industry, making it possible to then account for the necessary steam consumption, which was calculated as 2.765,54 kg h-1. Afterward the monetary values necessary for the company´s operation were estimated, accounting for fixed and variable costs, with subsequent evaluation of indicators, such as the discounted payback, the internal rate of return, the net present value and the break-even point, which indicate the feasibility of the project under the conditions indicated during the work.
Na fase de balanço de energia, levou-se em consideração os equipamentos que continham alteração de temperatura, para definição do gasto energético da indústria, sendo possível então contabilizar o consumo de vapor necessário, o qual, foi calculado em 2.765,54 kg h-1.
Após foram estimados os valores monetários necessários ao funcionamento da empresa, contabilizando-se custos fixos e variáveis, com conseguinte avaliação de indicadores financeiros, como o payback descontado, a taxa interna de retorno, o valor presente líquido e o ponto de equilíbrio, os quais, indicam a viabilidade do projeto nas condições indicadas durante o trabalho. O payback descontado retornou, nas condições propostas, o tempo de 4,15 anos para recuperação do investimento e o ponto de equilíbrio evidenciou a necessidade de produção de 5437,46 m3 de biodiesel para que a empresa passe a ter lucro.
Palavras-chave: biodiesel; microalgas; balanço de massa; balanço de energia; payback; ponto de equilíbrio.
Brecha digital de zonas indígenas como factor de exclusión social
Authors: Martínez Dominguez Marlen , Gómez Navarro Dulce Ángelica 
Published: December 2023

La brecha digital se reconoce como una forma de exclusión social que afecta en mayor medida a los pueblos originarios. En Oaxaca, por su alta composición de población indígena se observa un continuum histórico de desigualdades que se expresan en la pobreza, la marginación, la baja escolaridad y el bajo poder adquisitivo, que actúan como barreras para el acceso y uso de las TIC y enmarcan las brechas digitales. En este estudio se analizan los factores sociodemográficos, económicos, culturales y geográficos que inciden en el acceso y uso de las TIC por parte de la población indígena del estado, así como las políticas de inclusión digital emprendidas para el cierre de la brecha digital.
Los hallazgos revelan que la educación, el poder adquisitivo y las políticas de inclusión digital son condicionantes para fomentar el acceso y uso tecnológico. Se vislumbra la necesidad de diseñar y aplicar políticas digitales con la participación de los tres niveles de gobierno (federal, estatal y municipal) y agentes sociales locales, bajo un marco del reconocimiento de la diversidad cultural y lingüística, políticas más allá del carácter instrumentalista, que promuevan la inversión pública-privada en telecomunicaciones, además de seguir avanzando en mejorar el bienestar de la población indígena.
Reflexiones sobre modalidades pedagógicas, plataformización y educación en la universidad pública pospandemia
Authors: Pagola Lila Isabel , Zanotti Agustín , Grasso Mauricio 
Published: December 2023

El artículo reúne reflexiones relacionadas con procesos de plataformización social y sus consecuencias en universidades públicas de Argentina. Nos ubicamos en un escenario post pandemia, donde una “nueva normalidad” nos permite una cierta distancia sobre el período de excepcionalidad pedagógica. Al mismo tiempo, se evidencian desafíos emergentes a la hora de experimentar con modalidades pedagógicas que superan las divisiones clásicas entre lo presencial y a distancia.
Comprendemos que la pandemia de COVID-19 precipitó una serie de tendencias preexistentes en el ámbito educativo. Por ese motivo, nos interesa reconstruir procesos macro que vienen instalándose desde larga data. Para ello, hacemos foco en ciertas dinámicas informacionales, en particular aquellas relacionadas a los avances de la plataformización en la última década, junto a experiencias e impresiones sobre la implementación en instituciones de educación superior en la provincia de Córdoba.
Nuestras indagaciones dan cuenta, salvo importantes excepciones, de una falta de problematización y planificación de las nuevas infraestructuras digitales necesarias, frente a procesos estructurales de transformación de las prácticas sociales y educativas.
Metodológicamente el trabajo se sustenta en aportes conceptuales de diversas fuentes, así como la sistematización de experiencias docentes y de gestión educativa.
