Authors: Wang Di , Wang Wenbao , Bing Xue , Xu Chenguang , Qiu Jiahua , Shen Jiangang , Huang Jinwen , Li Junda , Xie Biao
Published: October 2022

Background: Ulcerative colitis (UC) is a recurrent inflammatory disease related to gut microbiota disorder. The metabolites and their sensors play an irreplaceable role in the communication of the gut microbes with their host. Our previous study revealed that G protein-coupled receptor 35 (GPR35) was a key guardian of kynurenic acid (KA) and a core element of the defense responses against gut damage. However, the mechanism remains unknown.
Results: In this study, a DSS-induced rat UC model was established and 16S rRNA sequencing was applied to explore the influence of GPR35-mediated KA sensing on gut microbiota homeostasis. Our results demonstrated that GPR35-mediated KA sensing was a necessary component in maintaining gut barrier integrity against UC-induced gut damage. More importantly, we provided strong evidences to support that GPR35-mediated KA sensing played a crucial role in maintaining gut microbiota homeostasis, which contributed to alleviate DSS-induced UC. Moreover, 5 classes including Actinobacteria, Beta-/Gamma-proteobacteria, Erysipelotrichi and Coriobacteriia, and 6 genera including Corynebacterium, Allobaculum, Parabacteroides, Sutterella, Shigella and Xenorhabdus were identified as the marked bacterial taxa that characterized the progression and outcome of UC and regulated by GPR35-mediated KA sensing.
Conclusion: Our findings highlight that GPR35-mediated KA sensing is an essential defense mechanism against the disorder of gut microbiota in UC. The results provide a profound insight in the key role of specific metabolites and their monitor in maintaining gut homeostasis.

Authors: A Ramesh , R Balasubramanian
Published: October 2022

Temperature-dependence correlations of vapor pressure and acentric factor for normalhydrogen(n-H2), orthohydrogen(o-H2) and parahydrogen(p-H2), have been formulated. The obtained correlations are statistically excellent. The characteristic parameters such as the Pitzer’s acentric factor, Riedel’s parameter, Filippov’s parameter have been determined for n-H2, o-H2 and p-H2. And, the curvatures of vapor pressure curve for n-H2, o-H2 and p-H2 have been determined in a wide range of temperature. It is found that the curvatures of vapor pressure curve for n-H2, o-H2 and p-H2 have a maximum at about 17.11K, 17.12K and 17.00K, respectively.

Authors: Belhadj Mohamed , Kromer Robin , Werda Sana , Darnis Philippe
Published: October 2022

Wire Arc Additive Manufacturing is a process with great potential and in full expansion for structural, maintenance and large-scale product development. It is gaining interest due to its low buy-to-fly ratio. Nevertheless, its major flaw is the low geometric accuracy and the wavy surfaces of the printed parts. To ensure that the requirements of the final part are respected, the dimensions and the minimum quantity of material to be machined have to be specified. Thus, Machining allowance and part dimensions are elements that were quantified based on a Design Of Experiments (DOE) and thermal analysis. It was used to determine the effects of Cold Metal Transfer (CMT) parameters on them. For instance, it was found that, travel speed and interpass time have a major influence on height, width and machining allowance. Specific way to achieve the desired requirements is discussed.
The Incidence Rate of AL Amyloidosis: A Systematic Review and Meta-analysis
Authors: Hanover Jeffrey , Buchner Jacob S
Published: October 2022

Introduction: AL amyloidosis is widely regarded as a rare disease, but characterization of its epidemiology has scarcely been reported. The purpose of this systematic review is to estimate the incidence rate of AL amyloidosis and examine population differences. Methods: MEDLINE, PubMed, and Google Scholar were searched from their inception until November 13, 2021 using search terms AL amyloidosis or immunoglobulin light-chain amyloidosis or light-chain amyloidosis or primary amyloidosis and incidence or epidemiology. Random-effects meta analysis of all cohort studies reporting an incidence rates for AL amyloidosis was performed. The quality of each study was assessed using a modified Newcastle-Ottawa scale. Subgroup analysis was performed based on geographical region. Results: Six studies with data from 2502 diagnosed cases of AL amyloidosis from 5 countries were included. The pooled incidence rate for AL amyloidosis was 10.48 per one-million person years (95% CI, 8.99 to 11.96). There was moderate heterogeneity in the data, which was eliminated with a subgroup analysis according to geographical region. AL amyloidosis was found to be more common in the Americas (incidence rate 11.52 per one-million person years, 95% CI 11.04 to 12.00) than in the Europe (9.10 per one-million person years, 95% CI, 7.62 to 10.58). Conclusion: There is a low worldwide incidence rate for AL amyloidosis, supporting the characterization of AL amyloidosis as a rare disease. The incidence of AL amyloidosis appears to vary in different populations, which suggests further well-designed studies are needed to elucidate underlying etiological factors and better inform clinical suspicion for AL amyloidosis.

Aims: The aim is to use of optical coherence tomography angiography to quantify vessel density throughout the different stages of diabetic macular edema progression.
Study design: prospective, cross sectional, observational study
Place and Duration of Study:University Hospitals in the period between March 2017 to March 2019.
Methodology:OCTA images were obtained using the AngioVue (Optovue Inc., CA, USA). For quantitative analysis of the VD with the help of the manufacturer’s automated software.
Results: The study included 160 eyes of 135 diabetic patients, 61 (45%) females and 74 (55%) males. The values of VD of the SCP were significantly affected more than the DCP very early in the diabetic course (No DR stage) (P=0.040). Moving one stage more in the disease (mild to moderate NPDR with no edema stage) the deep layer got significantly more affected than the superficial layer (P=0.038). In the more advanced stages of the disease and as the macular edema develop and progress (spongy edema and CME) the two plexuses showed decreased VD values nearly to the same degree with the deep plexus affected slightly more (low VD values) than the superficial plexus.
Conclusion: Using the OCTA machine with AngioAnalytics parameters (vessel density) aided in the objective quantification of macular perfusion in diabetic eyes with and without macular edema.

Authors: Mclish Laten Andre
Published: October 2022

Objective: To investigate the hypothesis that where bauxite soil is located in Jamaica people are
more prone to developing cancer of the lung.
Methods: This study encompassed all fourteen parishes. Data was obtained from the Jamaica
Cancer Registry located in the Pathology Department of the University of the West Indies.
Population denominators were obtained from the 2011 census taken by the Statistical Institute of
Jamaica. The statistical package which was used to analyze the data was SPSS.
Results: A total of 190 cases of cancer of the lung were examined across all parishes. It was
determined that the largest crude incidence rate occurred in Kingston and St. Andrew (9.8). This
was followed by St. Ann, St. Elizabeth, St. Catherine and St. Thomas. These had crude
incidence rates of 8.7, 8.7, 8.1 and 6.4 respectively. It was also determined that of the 190
persons who were diagnosed with cancer of the lung in 2008, 155 were males and 35 were
females. In St. Ann, St. Elizabeth, St. James and Westmoreland cancer of the lung was the
leading cancer.
Conclusion: When the distribution of cancer of the lung was closely examined in Jamaica 2008
the highest frequencies occurred in ages ranging from 55 years to 74 years. The mean age at
which diagnosis occurred was 65.4 years. There is also an indication that the presence of
uranium in the soil may have predisposed some persons in developing cancer of the lung.
A new model to calculate contributions of power distribution
Authors: Lin Whei-Min , Zhan Tung-Sheng
Published: October 2022

Besides metering, a more transparent load with known power distribution is valuable to draft energy strategies, especially in a deregulated power market. So the usage-of-transmission can be properly considered. There are many papers published on the related subject [1]-[42], and every research tried to solve a particular part of the problem. There are three basic categories for discussing power distributions: (i) the real power distribution, (ii) the reactive power distribution, and (iii) the loss allocation. These categories were very often treated separately, while with mutual coupling terms, counter flows, and line charging largely neglected. But we know that these entities are non-separable. These are closely inter-related entities; the change of one entity is closely related to the change of every other entity. A good method should consider these entities altogether, while satisfying all electrical theories. In this paper, a method is developed to solve the above problem, where all electrical entities can be solved, and all electrical circuit theories are satisfied. With several matrix formulations, this method is capable of solving and tracing all electrical entities including the current flow, the real and reactive power, the counter flow, and the couplings between the active and reactive power. The algorithm can also allocate power distributions and loss among participants effectively. Besides, a line usage concept is proposed to allocate the loss to each generator where counter flows can be awarded. It can be integrated to the existent tariffs in a deregulated market.

Published: October 2022

Methods of in vitro regeneration protocols were developed for three elite rose cultivars, Chewnicebell (Oso Easy Italian Ice®), Bucbi (Carefree Beauty™), and Cheweyesup (Ringo All-Star™). We evaluated the effects of different types and concentrations of auxins [dichlorophenoxyacetic acid (2,4-D) and trichlorophenoxyacetic acid (2,4,5-T)], carbohydrates [sucrose, glucose, and fructose], and cytokinins [thidiazuron (TDZ) and 6-bezylaminopurine (BAP)] on callus induction and regeneration from leaf explants. The greatest amount of regenerative callus was obtained on media containing 10 µM 2,4-D and 30 g·L−1 sucrose for Italian Ice® (40%), 10 µM 2,4-D and 60 g·L−1 glucose for Carefree Beauty™ (24%), and 5 µM 2,4,5-T and 30 g·L−1 sucrose for Ringo All-Star™ (32%). The greatest regeneration occurred when callus was transferred to media consisting of 1/2 MS media supplemented with 2.9 µM GA3 and 5 µM TDZ for Italian Ice® and Ringo All-Star™, and with 2.9 µM GA3 and 20 µM TDZ for Carefree Beauty™. Plantlets regenerated from callus were cultured on maintenance media and successfully transferred ex vitro. This study highlights the genotype-specific responses among rose cultivars and provides the first reports of in vitro regeneration for Italian Ice® and Ringo All-Star™.

Published: October 2022

This study investigated the effects of different sucrose, ventilation, and paclobutrazol (PBZ) treatments on the growth of potato plantlets cultured in modified temporary immersion culture vessels. Temporary immersion culture vessels were modified to enable the plantlets to be cultured on semi-solid growth medium and provided with forced ventilation. The plantlet responses to two sucrose concentrations (15 g⋅L−1 and 30 g⋅L−1) in combination with two forced ventilation treatments (5 min/2 h and no ventilation) and three PBZ concentrations (0, 0.2, and 0.4 mg⋅L−1) were studied. Shoot growth was severely inhibited by PBZ in the growth media, whereas leaf formation was promoted by ventilation irrespective of the PBZ concentration. In nonventilated vessels, it is noteworthy that PBZ was able to increase the number of leaves formed in plantlets grown on medium supplemented with 30 g⋅L−1 sucrose, but not on medium with 15 g⋅L−1 sucrose. In growth media without PBZ, a high percentage of potato plantlets was able to produce secondary axillary shoots when provided with 30 g⋅L−1 sucrose. However, their ability to produce secondary shoots was reduced when PBZ was included in the growth medium, particularly those with 15 g⋅L−1 sucrose. Plantlets grown in ventilated culture vessels combined with 30 g⋅L−1 sucrose in the growth medium produced more than three times more shoots than the other treatments. Under ex vitro conditions, plantlets that had been grown in ventilated vessels had fewer leaf deaths, and the inclusion of PBZ in the growth media further reduced the number of dead leaves. Findings of this study showed that PBZ had a key role in the responses of potato plantlets to ventilation and sucrose treatments, as well as their tolerance to ex vitro conditions. The modified temporary immersion system can be used for the in vitro culture of potato plantlets on semi-solid medium and provide forced ventilation to improve their growth.

Published: October 2022

The objective of this study was to investigate the effect of high-tunnel production on preharvest losses and harvest quality of two tomato (Solanum lycopersicum) cultivars. Our results indicate that using high tunnels for tomato production can reduce the preharvest food losses for this crop compared with open-field production, as indicated by increased productivity and percent marketability during the span of three production seasons. The tomato harvest quality did not differ in terms of physical attributes. However, open-field–grown tomatoes demonstrated a significantly greater antioxidant capacity when compared with the high-tunnel–grown tomatoes.

Published: October 2022

MicroRNAs (miRNAs) related to phytohormone signal transduction and self-incompatibility may play an important role in the xenia effect. However, associated research in this area is still lacking in rabbiteye blueberry (Vaccinium ashei). In this study, we identified miRNAs, predicted their target genes, performed functional enrichment analysis of the target genes, and screened for miRNAs related to phytohormone signaling and self-incompatibility. A total of 491 miRNAs were identified, of which 27 and 67 known miRNAs as well as 274 and 416 new miRNAs were found in the rabbiteye blueberry cultivars Brightwell and Premier, respectively. Compared with ‘Premier’, 31 miRNAs were upregulated and 62 miRNAs were downregulated in ‘Brightwell’. Kyoto Encyclopedia of Genes and Genomes (KEGG) functional enrichment analysis indicated that the 4985 target genes predicted were involved in biosynthesis of amino acids, plant–pathogen interaction, and spliceosome pathways. A total of 10, one, one, five, two, five, and two candidate miRNAs related to auxin, cytokinin, gibberellin, abscisic acid, ethylene, brassinosteroid, and salicylic acid signaling, respectively, in rabbiteye blueberry pollen were identified. Further analysis indicated that novel_miR_49 was a candidate miRNA related to self-incompatibility, and their target gene was maker-VaccDscaff21-snap-gene-21.37. In addition, the KEGG enrichment analysis of the target genes of novel_miR_49 showed that they were involved in the ribosome, aminoacyl-tRNA biosynthesis, and glycosylphosphatidylinositol-anchor biosynthesis pathways. The results revealed that the microRNAs of rabbiteye blueberry pollen regulated to phytohormone signal transduction and self-incompatibility signal transduction based on related to auxin, cytokinin, gibberellin, abscisic acid, ethylene, brassinosteroid, and salicylic acid signaling. Results suggest that more research of the effects of miRNAs on regulation of hormone signal transduction and self-incompatibility is necessary for elucidating the molecular mechanism of the xenia effect.
Aspects of life cycle in its projection onto production of meat and meat-containing canned food: systematic review
Authors: Gustova T. V.
Published: October 2022

While choosing one or another product from a wide variety on the market, we intuitively focus on the quality of the food product, we pay attention to its source, raw material and how this food is made. At the same time, the same questions are being asked by food manufacturers as they want to be sure of the quality and safety of purchased raw materials and ingredients. In both cases, decisions should be based on the consequences they could entail. It must be acknowledged that any failure in the field-to-shelf chain system may harm the consumers’ health, as well as may lead to disruptions and losses in the food industry. Producers and consumers are increasingly concerned in the terms of life cycles. The life cycle is the most expressive and comprehensive approach to achieve the highest usefulness of the made decisions. The fact is that life cycle problems can be solved, and product life cycles can be managed, controlled and regulated. This is widely applied, for example, by the use of life cycle methodology in solving environmental problems highlighted in this article. However, in the meat processing industry the standards of the ISO 9000 series are not supported by this methodology. It was necessary to find and define the problem-exposed stages from the full life cycle of production of meat and meat-containing canned food within the system “from the field to the shop shelf”. Those problem-exposed stages are responsible for safety and quality of canned food and responsible for maintaining the safety and quality of ready-to-eat food products, as the most relevant stages in the meat processing industry. Here the author proposes for consideration three stages of the life cycle of canned meat and meat-containing food, including its pre-production, production process and post-production. It is assumed that the impacts at certain limited stages of the canned food production cycle will be representative in terms of consequences of applied decisions.

Published: October 2022

Structural characteristics of a certain type of gas turbine double rotor and its hull are analyzed. The wave of a regular form is considered, and the wave load is simplified to the form of sinusoidal force. The rubbing force and nonlinear supporting force of the bearing are deduced as per the Hertz contact theory and Coulomb friction law. The mechanical model of the double rotor system under the combined action of the wave load and rotor friction impact is established, which is solved by the fourth-order Runge-Kutta method. The bifurcation diagram, phase diagram, Poincare section diagram, axis trajectory diagrams, effects of rotor eccentricity, and friction coefficient on the nonlinear dynamic characteristics of the system under rub impact fault are studied. The obtained results show that with an increase in eccentricity, the system enters into a chaotic state through the period doubling and paroxysmal bifurcations, and successively experiences nonlinear behaviors such as periodic 2 bifurcation, periodic 4 bifurcation, and quasi periodic and chaos. In the double rotor system, the nonlinear dynamic behavior of the single period and semi Nermark-Sacker bifurcation occurs with increasing friction coefficient. The present findings can provide a theoretical basis for condition monitoring, fault diagnosis, and design optimization of this type of gas turbine double rotor system.

Published: October 2022

The tooth contact analysis model is introduced for cylindrical gear with high-order topological modification and misalignment. According to the generation principle of gear, the tooth surface equation of double-crowned gear by using worm grinding wheel is derived. Based on the gear meshing theory, a tooth contact model of cylindrical gear considering errors and high-order topological modification is established. Taking helical gears as an example, the effects of errors and four different combinations of modification curves on the contact marks and transmission errors of tooth surface were analyzed. Results show that the paths of contact change dramatically with different combinations of modification curves. With the increasing of the order of modification curve, the contact path transitions smoothly in the middle of the tooth width, while the total length of the major axis of the contact ellipses increase significantly compared with taking the quadratic parabola modification. With proper parameters of the modification, the apex of transmission error function is flatter and its amplitude decreases which further reduces the vibration of gear transmission to installation error. The finite element method is applied to validate the proposed analysis model. The results are basically consistent and the maximum error is within 3.5 %.

Published: October 2022

Increased energy demand and fossil fuel usage of the world has led to the search for new and clean energy production methods. Renewable energy sources are developing and emerging options for energy production methods. Sun is the most accessible and stable renewable energy source. There are several methods to produce energy from the sun. The building-integrated photovoltaic (BIPV) system is a well-known method for generating electricity by using solar cells to transform the energy from the sun into electricity. BIPVs are a new technique to reduce energy consumption from fossil fuels. Passive solar houses mean that the energy demand of the living space is met with the usage of solar energy for the heating and cooling demand of the living space. In this study, an existing house, located in Istanbul, is modeled and covered with photovoltaics with the help of a computer program and the amount of energy produced with the aid of these photovoltaics is presented. The analysis demonstrates that the yearly average amount of daily electricity production is varied between 1.05 kWh as the minimum value and 19.7 kWh as the maximum value for all facades. The yearly average amount of monthly electricity production is varied between 31.8 kWh as the minimum value and 599 kWh as the maximum value for all facades.

Authors: ŞUMNU Ahmet
Published: October 2022

In the present study, effect of side devices and crosswind flow are investigated to observe aerodynamic drag coefficient for a simplified ground vehicle (Ahmed body) since it directly effects fuel consumption. When the literature was examined, the studies that were investigated effect of slant angle, velocity and geometric modifications were presented. However, there are few studies that proposed both side device effect and crosswind flow for ground vehicles at different yaw angles. The CFD (Computational Fluid Dynamic) solution is performed both model with side devices and crosswind flow condition. The crosswind flow condition has been analyzed at different yaw angles (β=5°, 10°, 20°, and 30°) to observe how to affected drag coefficient. Pressure contours have been presented for model with and without side devices and under the crosswind flow conditions at rear region of body since the most of the drag force occurs flow separation or adverse pressure gradient. The streamlines velocities have been presented at x-plane which is positioned side devices location under the crosswind flow conditions. In addition, vorticity magnitude has been given for both models with and without side devices at different yaw angle. In the results of study are observed that side devices adversely effects aerodynamic performance since flow separation occurs on the side of body and it causes to increase pressure drag. The pressure drop is also observed at rear region of model due to crosswind flow condition. This causes the increase of drag forces.

Published: October 2022

Objectives: Retinopathy of prematurity (ROP) is a vasoproliferative disease that affects premature infants.The purpose of the study is to identify various maternal and fetal risk factors for ROP and to categorize the premature babies according to severity of disease and associated risk factors.
Methods: This is a cross sectional study conducted on 100 infants from May 2021 to August 2021. Examination was done by a single ophthalmologist specialized to screen the babies. It was done 4 weeks after the birth and Detailed history included the birthweight, gestational age, the postnatal problems, obstetric history were obtained. Pupillary dilatation was done with a mixture of 2.5% phenylephrine and 1% tropicamide.0.5% proparacaine is used for topical anesthesia. An infantile lid speculum was used to separate the lids. Fundus was examined with binocular indirect ophthalmoscope and +20D condensing lens.
Results: Prematurity and low birth weight are the most common and important risk factors. Most of the babies had symmetrical disease (88%) and zone 3 is most commonly involved (67%).Apart from prematurity and low birthweight, respiratory distress syndrome with oxygen supplementation was common association (56%).Various maternal risk factors were found to be common associations like pre eclampsia (33%) and gestational diabetes (22%).
Conclusion: ROP is associated with several maternal and fetal risk factors. Early detection by screening of the premature babies can prevent blinding complication. Inadvertent and generous oxygen administration must be stopped due to its high association with ROP. All the premature babies must be screened 4 weeks after gestation for the earliest detection of the disease with an ophthalmologist specialized in that field with regular followups and prompt intervention as soon as the disease is identified.

Objective: The objective of the study was to compare the effects of dexmedetomidine versus midazolam-fentanyl on post-operative recovery, sedation, analgesia, and hemodynamic parameters in patients undergoing middle ear surgery under local anesthesia.
Methods: Seventy-two patients were randomly divided into two equal groups - Group D (dexmedetomidine) and Group MF (midazolam and fentanyl). Intra operative heart rate, mean blood pressure, respiratory rate (RR), and SPO2 were recorded every 15 min for the 1st 30 min and then at every 30 min interval till the end of the surgery. In post-operative period, hemodynamic parameters, Aldrete score and pain were assessed at every 30 min till the patient was discharged from post anesthesia care unit (PACU). Post-operative sedation of the patient was checked at 1 h, 2 h, 4 h, and 8 h.
Observations: Midazolam and fentanyl combination caused more fall in Aldrete scores as compared to dexmedetomidine initially, but readiness to discharge from PACU was similar in both the groups. Patients of MF group had significantly higher sedation scores at post op 2 h, but overall duration of sedation was similar in both the groups. Post-op pain was significantly more in MF group patients, as compared to dexmedetomidine patients at 1.5 h. More number of patients of MF group demanded rescue analgesia in PACU. Both group of drugs caused similar changes in hemodynamic parameters during surgery but in post-operative period, dexmedetomidine produced less decline in RR and oxygen saturation as compared to midazolam and fentanyl combination.
Conclusion: The present study concluded that dexmedetomidine seems to be a better alternative to the combination of midazolam plus fentanyl sedation for patients undergoing middle ear surgeries done under local anesthesia due to better analgesia and lesser derangement of hemodynamic parameters in post-operative period.

Introduction: Epidemiology plays an important role in providing interpretation of disease occurrence in populations, change of disease rate, and the associated factors related to occurrence. Physical health problems not only coexist with mental disorders such as depression, but can also predict the onset and persistence of depression. A study of a nationally representative sample of the United States showed 79% of all ill people were comorbid.
Aims and Objectives: The aims of this study were to study the comorbid condition in subjects with common mental disorders (CMD).
Methods: It was a community-based and cross-sectional study carried out in an urban Slum. Slum was divided into four quadrants and 10% of the population was taken. A total of 150 houses were visited by random sampling and the sample size was calculated to be 294. The study was recorded in a pilot tested pre-designed validated semi-structured questionnaire. Four hundred and twenty-three out of 467 people were included in the study which was conducted in two phases. First phase was the screening phase which included history, general examination, and demographic profile along with self-reporting questionnaire (SRQ-20) to measure the presence of mental illness. Socioeconomic status of family and quality of life was evaluated using Kuppuswami socioeconomic status scale. Subjects scored 7 and above selected for the study and further evaluated using mini international neuropsychiatric interview plus in the second phase.
Results: In the present study, highest percentage of CMD was 26.47%, belonging to 16–25 age group and distress was found in 16.07% and severe distress in 7.80% with SRQ-20 scoring between 7 and 13 and >14, respectively, with higher proportion of females. The prevalence of CMD was 238.77/1000 and 11.88% and 8.91% subjects were found hypertensive and diabetic respectively.
Conclusion: There is need to consider the impact of common psychological health problems that urban slum communities are facing today and CMD can be a major contributor to slum’s overall burden of functional impairment.

O presente artigo traz uma discussão reflexiva acerca do tema Interculturalidade crítica, objetivando evidenciar a diferença fundamental entre o termo interculturalidade e multiculturalismo, dando destaque para a característica de cada um e para o surgimento e utilização destes. Concebida como um tema bastante polêmico, a interculturalidade está atrelada aos ideais de liberdade, universalidade de direitos, independência e transparência, sendo estes fatores essenciais para o exercício das democracias modernas. Dessa forma, o termo acima citado tem se destacado como premissa na redação das cartas magnas de alguns países, principalmente daqueles que possuem em sua população um grande contingente de habitantes nativos, como é o caso dos povos indígenas dos países da América Latina, sendo que esses grupos étnicos têm reivindicado através dos movimentos sociais, que a interculturalidade se torne não apenas uma promessa de Governo, mas uma política de Estado. A interculturalidade crítica, teve sua origem no movimento pós-colonialista, formada a partir de um conjunto de concepções advindas de uma militância de teóricos e críticos, que através de uma análise reflexiva firmaram tais concepções e teorias nos estudos culturais. Tal conceito ganhou amplitude, implicando assim o reconhecimento deste por outras correntes e áreas do conhecimento de caráter epistemológico como uma escolha libertadora e emancipatória.

Neste artigo, apresentamos elementos-chave que caracterizam a experiência-piloto do curso de Licenciatura em Educação do Campo – áreas de concentração Ciências Humanas e Sociais e Ciências da Natureza e Matemática –, da Universidade Federal de Sergipe (UFS), em São Cristóvão, realizado entre 2008 e 2012. Nesse curso, 43 alunos receberam o título de graduação para atuar nos anos finais do ensino fundamental e no ensino médio. O texto apresenta elementos e reflexões acerca dessa proposta de formação dos professores, que foram produzidos por meio da análise documental e do levantamento bibliográfico. No geral, os resultados mostram que, embora o curso tenha contemplado demandas dos movimentos sociais do campo, não houve garantia por parte do Estado para a sua continuidade, uma vez que não se constituiu em política pública permanente. Além disso, não foram adotadas medidas para que os educadores egressos fossem absorvidos na rede pública de educação por meio de concurso público. Com isso, ainda se convive com o desafio da ausência de profissionais com formação específica para atuarem nas escolas do campo. Pretendemos, com isso, contribuir com a memória da Educação do Campo no Brasil, cujo projeto tem sofrido graves inflexões por conta da destruição das políticas públicas de educação, como na atual conjuntura em que o país enfrenta, uma crise econômica, política, social, cultural, ambiental e sanitária, com o governo Bolsonaro. O Estado de Sergipe é apenas um exemplo do que vem ocorrendo em território nacional. É para ontem, pois “se o campo não planta, a cidade não janta!”.

The second law of thermodynamics uses change in free energy of macroscopic systems to set a bound on performed work. Ergotropy plays a similar role in microscopic scenarios, and is defined as the maximum amount of energy that can be extracted from a system by a unitary operation. In this analysis, we quantify how much ergotropy can be induced on a system as a result of system's interaction with a thermal bath, with a perspective of using it as a source of work performed by microscopic machines. We provide the fundamental bound on the amount of ergotropy which can be extracted from environment in this way. The bound is expressed in terms of the non-equilibrium free energy difference and can be saturated in the limit of infinite dimension of the system's Hamiltonian. The ergotropy extraction process leading to this saturation is numerically analyzed for finite dimensional systems. Furthermore, we apply the idea of extraction of ergotropy from environment in a design of a new class of stroke heat engines, which we label open-cycle engines. Efficiency and work production of these machines can be completely optimized for systems of dimensions 2 and 3, and numerical analysis is provided for higher dimensions.

Published: October 2022

This study is devoted to the consideration of the peculiarities of the policy of the EAEU states in the field of artificial intelligence (AI) in the context of global technological confrontation.Aim. To identify the key directions of the strategy of the EAEU member states in the field of AI, as well as to identify priority policy directions in this area at the union level.Tasks. To analyze the results of the development of the AI industry in Armenia, Belarus, Kazakhstan, Kyrgyzstan and Russia, to consider the main economic indicators, achievements in the creation of computing infrastructure, the development of their own research and development in the field of AI, to identify the main provisions of the key official documents of the EAEU member states in the field of AI. To identify the main directions of AI policy at the Union level.Methods. Research of official documents and on the basis of information and analytical technologies, comparative analysis, content analysis, inductive method using approaches of critical geopolitics.Results. The study showed that the policy of the EAEU countries in the field of AI is characterized by a focus on external technologies and investments, the creation of hotbeds of technological growth, largely due to the efforts of large commercial organizations around which the AI ecosystem is being built, including infrastructure, education and R&D. In conditions of relatively small domestic investments, the implementation of research and development results is largely associated with participation in international outsourcing projects. Against the background of increasingly escalating global technological competition, it is of paramount importance for the EAEU to strengthen its own technological sovereignty and to develop as soon as possible a unified union policy in the field of the most advanced technologies, including in the field of AI, as a conceptual basis for the development of bilateral and multilateral cooperation formats both within the EAEU itself and with other countries.Conclusions. International cooperation in high-tech spheres is becoming particularly relevant not only in the context of the accelerating transition to a new technological order, but also against the background of escalating trends of decoupling, concentration of technologies, tightening of sanctions policy. For the EAEU, the development of a unified AI policy is of priority importance, which will contribute to the intensification of scientific and technical cooperation, strengthening integration potential and technological sovereignty.
