Published: November 2022

Colitis caused by vasculitis is a rare and poorly understood pathology. Little evidence exists on its clinical presentation, path to diagnosis, and surgical management. In this report, we present a case report and literature review. A healthy 20-year-old male patient presented with hemorrhagic colitis requiring total colectomy with end ileostomy. Pathological examination showed pancolitis with multiple ulcers, transmural inflammation, hemorrhage, and microvascular thrombosis. Extensive serological testing revealed elevated cytoplasmic antineutrophil cytoplasmic antibody (c-ANCA) and eosinophilia, leading to a diagnosis of eosinophilic granulomatosis with polyangiitis (EGPA) and vasculitis-induced colitis. A literature review was subsequently conducted. Nineteen studies were found documenting vasculitis-induced colitis in the absence of inflammatory bowel disease (IBD). Systemic signs of vasculitis, hemorrhagic colitis, and progression to fulminant colitis were present. Of all patients, 40.0% required colorectal surgery and 62.5% of those patients received a stoma; 25% underwent emergency surgery following failed immunosuppression. All cases relied on clinical correlation with serology and/or histopathology to reach a final diagnosis. We report a case of vasculitis-induced colitis caused by c-ANCA−positive EGPA. The review shows that vasculitis-induced colitis without IBD is an important differential that clinicians should be aware of in patients presenting with colitis.

El artículo presenta los resultados preliminares de una investigación sobre las condiciones y condicionantes de la continuidad pedagógica en el nivel secundario bonaerense. En este marco, interesa recuperar investigaciones sobre la intensificación del trabajo docente y estudiar sus nuevas dinámicas a la luz de la  reconversión de los escenarios laborales producto de la dilución de las fronteras entre el hogar y el trabajo y de las nuevas regulaciones políticas frente a la pandemia para dar cuenta de cómo afectan la toma de decisiones pedagógicas bajo estas inéditas circunstancias en la provincia de Buenos Aires.  Analizamos estas dimensiones centrales —escenarios, política y prácticas— dando cuenta de las dinámicas de la desigualdad cuyo agravamiento es parte del debate académico en curso, distinguiendo tanto las condiciones de género y las asimetrías en la distribución de las tareas de cuidado como la heterogeneidad en las condiciones sociosanitarias en los territorios,  vinculadas con las condiciones de cuidado frente a la pandemia. Se reconstruyen narrativamente para ello las políticas implementadas a lo largo del  2020 y se recuperan los resultados de una encuesta aplicada a docentes frente a curso aplicada entre los meses de septiembre y octubre del mismo año en cuatro distritos que expresan la heterogeneidad territorial de la jurisdicción.
Del ASPO al DISPO: la agenda de política educativa y los posicionamientos públicos frente a la presencialidad (2020-2021)
Authors: Di Piero Emilia , Miño Chiappino Jessica
Published: November 2022

A partir de la suspensión de las clases presenciales en Argentina ante la propagación del COVID-19, en marzo de 2020 se impulsaron planes de continuidad pedagógica a distancia a nivel nacional y subnacional, lo cual implicó la apuesta a una suerte de “virtualización forzosa”. Este artículo se propone analizar la agenda de política educativa en el periodo que se extiende desde la medida de Aislamiento Social Preventivo y Obligatorio (ASPO) hasta el posterior Distanciamiento Social Preventivo y Obligatorio (DISPO), enfocándose en tres dimensiones específicas: la articulación de las propuestas educativas entre el nivel nacional y los niveles jurisdiccionales, los nuevos temas en la agenda educativa emergentes a fines del año 2020 y los debates en torno a la presencialidad considerando los posicionamientos de distintos actores. Los documentos analizados muestran un viraje desde la preocupación por la elaboración de contenidos centrados en los procesos de enseñanza y de aprendizaje hacia nuevos temas en agenda ligados a la revinculación, la evaluación y la conexión entre los ciclos 2020-2021. A su vez, las tensiones y posicionamientos ante la política de retorno a la presencialidad evidencian ciertos rasgos propios de los modos de regulación postburocráticos. Se realizó un estudio exploratorio de las 24 jurisdicciones a partir del relevamiento de las plataformas, páginas web de organismos estatales, documentos provinciales y nacionales, de organizaciones médicas y de la sociedad civil en tres bimestres: abril-mayo y noviembre-diciembre de 2020, y enero-febrero de 2021.

The COVID-19 pandemic, and measures put in place to try to control it, impacted the psychosocial wellbeing of children and adolescents. Teachers reported an increasing trend of challenging and disruptive behaviours among school children. This rapid review evaluates the effectiveness of interventions to address challenging and disruptive behaviours within schools and further education colleges. Early searches conducted in May 2022 identified no relevant studies during the pandemic. This rapid review therefore sought research publications in the five years before the pandemic and during the pandemic, i.e., from 2015 to 2022. Three primary outcomes were the focus of detailed consideration: sexual harassment, attendance/truancy, and school exclusion/suspension.14 studies were identified of school-based interventions: 10 randomised controlled trials and 4 non-randomised controlled trials. Based on the findings of recent controlled studies there is no strong evidence to suggest that multi-component school-wide interventions or training/support for students will lead to improvements in sexual harassment (in the longer term at least), attendance or exclusion/suspension outcomes in schools.Training and educational interventions to reduce sexual harassment may be effective in the short term in some settings, but it is unclear as to ‘what might work for whom’ in the short term, and whether benefits can persist in the longer term.There is moderate evidence to suggest that neither school-wide nor training/educational interventions affect school attendance, but 5/7 studies were conducted in primary schools. Evidence for older age groups is lacking.More evidence is needed in relation to school exclusion/suspensions, but limited evidence suggests that high fidelity to a school-wide approach may have positive effects on frequency and duration of school suspensions. Further analysis is needed.Confidence in the findings on attendance/truancy is moderate, whilst confidence in the findings on sexual harassment and school exclusions/suspensions is low.

Published: November 2022

En los últimos años los Estados de América Latina han concertado acuerdos y estándares regionales e internacionales para abordar la violencia contra las mujeres, pero, a pesar de tener importantes avances, este flagelo sigue siendo una amenaza para los derechos humanos, la salud, la seguridad ciudadana, la libertad política y económica de las mujeres en la región. Por esta razón se hace necesario adoptar medidas públicas que ayuden a mitigar y/o eliminarla violencia contra la mujer. El propósito de esta investigación fue identificar las políticas públicas en materia de violencia contra la mujer en Latinoamérica. Se aplicó el método de análisis documental, con un enfoque cualitativo, diseño no experimental, con un nivel documental bibliográfico transversal. Como resultado, se observó que la violencia contra la mujer en América Latina ha incrementado en los últimos años, debido a factores políticos, sociales y económicos en la región, así como la emergencia sanitaria por COVID-19. Se concluye que, aunque el Estado implementa políticas públicas encaminadas al tratamiento de la violencia contra la mujer, estas no han logrado disminuir los índices de violencia, por el contrario, han ido en aumento.
A gate leakage current-powered loadless 4T SRAM with immunity against random dopant fluctuation and surface roughness in silicon-silicon dioxide interface
Authors: Zhu Yihan , Ohsawa Takashi
Published: November 2022

The sensitivities of the data hold, read and write performances for the gate leakage-powered loadless 4T SRAM cell on the variations in the MOSFETs’ gate leakage currents are examined by SPICE Monte Carlo simulations in 32 nm technology. The standard deviations in the gate leakage current variations are taken from the device simulation results in which the variations are caused by the random dopant fluctuation and the surface roughness in silicon-silicon dioxide interface. It is shown that the static noise margin (SNM) in the data hold state is 60 mV at 1 V power supply voltage for the −5σ cell with the MOSFETs’ threshold voltage variations taken into consideration. The read SNM and the write SNM are shown to be 160 mV and 440 mV for the −5σ cell, respectively, which are better than the 6TSRAM cell.

Published: November 2022

Ultraviolet photodetectors (UVPDs) based on Si-Zn-SnO (SZTO) thin-film transistors (TFTs) with a stacked dual-channel layer (DCL) structure with different carrier concentration and NiO capping layer (CL) to alleviate the trade-off between dark current (I
dark) and photocurrent (I
ph) are reported. Experimental results show that under 275 nm irradiation, the proposed SZTO TFT UVPD with a 30 nm thick upper layer stacked on a 50 nm thick channel layer and a patterned NiO CL exhibit excellent photoresponsivity and photosensitivity up to 1672 A W−1 and 1.03 × 107 A A−1, which is about 272 and 137 times higher than conventional 30 nm thick single-channel layer SZTO TFT. These improvements are due to the use of a DCL which forms a high-low junction to reduce the effective channel thickness and increasing the space for UV illumination and the use of NiO CL lowers the I
dark and causes a considerable negative threshold voltage shift under UV irradiation to significantly boost the I
ph.

Grinding of the components of the feed mixture and granulation are the most important operations in the technology of feed production according to zootechnical requirements. The subject of the study are different designs for grinding protein feed. A comparison was made by patent search of the design features of grinders of sunflower cake and grain. It has been established that hammer-type crushers are most widely used for crushing sunflower cake. The analysis revealed the following shortcomings of hammer-type crushers: high metal and energy consumption, uneven particle size distribution of the crushed product, large release of dusty fraction, significant rotating masses, rapid wear of working bodies, heating of the product. The advantages of crushers include the quality of the crushing process. The following conclusions are made. Improvement of sunflower cake grinders should be aimed at expanding its functionality, reducing the energy intensity of the process and improving the quality of its grinding due to the presence of a set of removable knife blocks with crankshafts with different necks for processing material with different physical and mechanical properties or knives in the form of a curvilinear triangle Arbelos Archimedes with sawtooth teeth along the perimeter of the entire surface of the cutting edge, while the entire surface of the cutting edge of the knife is involved in the technological process and sliding cutting is carried out.

Legumes are a great reserve of high-grade protein feed for pig production, creating a solid base for the production of import-substituting additives that provide a balanced feeding of animals and increase the competitiveness of the industry. It is recommended to extend a science-based use of vegetable protein, especially legumes, using special technology of processing of raw materials for inactivation of anti-nutritional substances. It was established that the technological processing of soy and lupine (micronizing, flaking, extrusion) improves the quality characteristics of the feed, which is beneficial to absorption of nutrients. Studies have shown that the use of micronized, extruded and autoclaved soy and shelled extruded lupine reduces the cost of the balancing concentrate without compromising its quality. At the same time, the productivity of animals does not decrease, the intestinal microbiocenosis does not go beyond the norm, and the metabolism remains at a high level. This has been shown to improve nutrient absorption. The optimal mode of moisture-thermal treatment of soybeans by the micronization method was determined: soybean moistening up to 19%, its IR irradiation for 60 s at a temperature of 130 ° C, followed by tempering (exposure) at 90 ° C for 15 minutes. A technological scheme for the manufacture of balancing concentrates is given. These concentrates are cheaper than fishmeal, their use allows you to reduce the cost of feed, get additional income and, as a result, contributes to the high profitability of the pig industry.The composition of high-grade protein concentrates are maked. The productivity of animals is not decreased bowel microbiocenosis did not go beyond the limits of Maximum Permissible Concentrations, digestion of nutrients was high enough. It is shown that it is beneficial to the assimilation of nutrients. Optimum processing mode using moisture and heat by micronization soya: soya hydration to 19%, an IR irradiation 60c for her at 130 ° C with subsequent tempering (extract) at 90 ° C for 15 minutes is defined. Technological scheme for producing of additives is shown. Are developed highprotien concentrates alternatively to import analogues and forages of an animal origin for mixed fodders. Industrial tests of mixed fodders with different developed concentrates in the conditions of pig-breeding complexes on different stages was fulfill. Growth of pigs are registrated.

The regularities of the distribution of torques on axles and tractor wheels have been studied. An energy-saturated universal tractor of class 2 integrated circuit LTZ-155 with all driving and steered twin wheels of the same size with tires of size 9.5-42 was chosen as the object of research. The studies were carried out under the following layout options and driving conditions: 1) rectilinear movement of a separate tractor - idling; 2) execution of the technological process during operation of the machine-tractor unit in row spacing of row crops - cultivation; 3) rectilinear movement of a machinetractor unit with guns in the transport position - idling. It was found that the total values of torques on tractor wheels under relatively constant driving conditions for all experimental races with an increase in translational speed of movement slightly, by about 5... 18%, increase due to an increase in the frequency of the dynamic impact of the microprofile from the side of the bearing surface on the wheels and fluctuations in the traction load. At the same time, the mean square deviation of the wheel moments does not exceed 18... 25% of their average value, which is constant for a stationary ergodic process. With the considered variants of operation of the machine-tractor unit, the redistribution of torques, both on the axles and on the wheels of each axle, even if we assume that a constant total torque is supplied to the driving wheels, is very complex and dynamic, due to the inaccuracy of landings due to the tolerances of the coupling in the coupling device between the tractor and the cultivator from- due to the inability to comply with the alignment of the covered and encompassing connecting elements of the connecting triangles, this leads to an asymmetry of the normal weight load of the wheels from the mounted guns and the corresponding non-proportional distribution of traction forces on the wheels.

It is known that one of the most effective ways to improve the traction performance of wheeled vehicles is to increase the area of contact between the propeller and the supporting surface. The performance indicators from the use of tires of increased dimension are presented, by reducing the level of unproductive losses for self-movement, slipping and processing of over-compacted soil along the tire track. The results of comparative assessments of traction and operational and technological indicators of the T-150K tractor on plowing with serial tires of dimension 21.3R24 and tires 66x43R25 with DW36x25 disks are presented. As a result of the study, an increase in the traction efficiency of the tractor on a stubble background by 11 - 44.5% was obtained. An increase of 1.36 times in the traction force developed by the tractor compared to the serial version with a slipping level of 15% was obtained. Comparative evaluation of performance indicators found that when working with a 5-furrow plow, the performance of the unit with 66x43R25 tires was 40% higher than that of the serial sample, and per hectare fuel consumption was 38% lower. When working with a 4-furrow plow, the differences in productivity by options amounted to 36%, and specific fuel consumption - 32%.
METHOD FOR DETERMINING THE OPTIMAL LENGTH OF THE TRIER CYLINDER

. It is known that agricultural enterprises are equipped with grain cleaning units of the ZAV40 and KZS-40 types. It is known that in 90% of cases trier blocks of units are taken out of service, since they do not provide the required quality of grain cleaning and are unreliable in operation - technological failures occur due to blockages of cellular cylinders. This problem can be partially solved by using indented blocks with the optimal length of the indented cylinder. This will lead to a significant reduction in the loss of clean grain to waste while maintaining an acceptable level of residual contamination and increasing reliability. A mathematical model has been developed for the operation of the grading unit according to the parameters of residual contamination and losses of clean grain. It was found that the residual contamination decreases exponentially along the length of the doll cylinder. The loss of clean grain to waste grows linearly. It was found that the loss of pure grain to waste along the length of the oat cylinder decreases exponentially. A formula has been obtained to determine the optimal length of the indented cylinder, which depends on the degree of impurity release and the amount of pure grain loss for the doll cylinder. The criterion of optimal operation of the indenter block has been substantiated. The hypothesis about the same degree of impurity release along the entire length of the indented cylinder was confirmed. On the basis of the results obtained, recommendations are given for the developers of indented blocks.

An analysis of the operating conditions for the use of grain cleaning technologies is given. The necessity of automatic adjustment of the speed mode of the trier operation, taking into account the variability of the supply of grain mixture, is substantiated. A constructive scheme of the transmission mechanism of the automatic control system for the operation of the trier is proposed. It is substantiated that the relationship of the angles of rotation of the control and controlled links with the advance of the increment of the latter in the entire range of regulation is provided with a sliding contact between them. The rotation angle ranges of the control (α) and controlled (β) links are 19° and 27.6°, respectively. It is theoretically confirmed that the initial ratio of increments of angles (Δβ and Δα) is 1.4, and the final one is 1.75. This ensures a high quality of reproduction of the optimal high-speed modes of operation of the trier for each of the six levels of the interval-changing value of the feed of the grain mixture. The initial values of the lengths of the control and controlled links from the point of their contact to the axes of rotation are 70 and 50 mm, respectively. The initial position of the control link relative to the horizon is 54.75°. Its rotation together with the shaft of the regulator valves before contact with the controlled link, when the supply Wmin = 1.2 t/h is ensured, is 35.75°. Setting the controlled link on the handle of the fixed resistor to its original position is carried out after it is rotated through an angle of 172.1°, which ensures the minimum speed of the trier - nmin = 34 rp/m.

The use of vacuum technologies and equipment in the processing of agricultural products can significantly reduce the loss of biologically active substances and functional components in the final product. Liquid ring vacuum pumps (LHVN) are considered in the work. A significant disadvantage of the LHVN is its low efficiency (about 50%), which is due to hydraulic losses due to friction of the liquid against the stationary pump casing and excessive power consumption for compressing the gas phase. A new design of a combined LHVN with a kinematic lock and an adjustable discharge window (LHVN KM) is proposed. The design allows to reduce the power consumption for the friction of the working fluid against the body; in the initial modes of operation - to minimize over compression and overflow of the gas phase from the injection area to the suction area; at limiting operating modes - to ensure the displacement of the gas phase from the working cavity and eliminate the effect of "locking", accompanied by destabilization of the working process. A standard size range of LHVN KM for various technological processes is presented. For LHVN KM of especially high speed of action, it is proposed to carry out the working process by rotating the body with blades through the designed drive. The scheme and methodology for calculating the drive on the basis of GOSTs and known methods for calculating gearing are described. In order to reduce the weight and size parameters of the LHVN KM, it is proposed to manufacture drive and pump parts from polymeric materials with subsequent hardening by a magnetothermal method.

The interaction of seeds with a capacitive seeding sensor is necessary to study and determine the duration of the flight of one seed through its sensitive elements to ensure high-quality and reliable operation of the automatic control system for the position of the doubles puller. The research was carried out with seeds of various crops: soy (variety “Lisbon”), corn (variety “Falcon”), lupin (variety “Delta”), sugar beet for experiments (fraction: 3.50–4.75). The values of the time of flight of seeds through the sensitive elements of the seeding sensor were determined with an accuracy of one millisecond in the course of laboratory studies and displayed on the display in the form of a graph, stored in the computer's memory and then processed by methods of mathematical statistics. Data on the time of flight of seeds through the capacitive sensor, which are for: soybean - from 11 to 13 ms, lupine - from 11 to 14 ms, sugar beet - from 7 to 9 ms, corn - from 12 to 14 ms were obtained from the results of research. They practically do not change in the operating speed range of the sowing unit (sowing disc rotation frequency 20 - 60 rpm), and can be taken as the time of flight of one seed in further calculations.The obtained data will allow to determine more detailed information about the operation of the sowing unit (skips, twins, damaged seeds), which will significantly increase the functionality of the seeding control systems used.

The restoration of body parts by applying elastomeric coatings eliminates wear on the holes, increases the life of the part and bearings, and significantly reduces the cost of repairing the car. The filling of the elastomeric matrix with nanoparticles allows a significant increase in the operational properties of the material. The influence of the content of aluminum filler nanoparticles, as well as the mode of thermal treatment by convective method on the deformation-strength properties of the F-40S elastomer-based nanocomposite were investigated. The mechanical properties of the nanocomposite films were evaluated according to the method of GOST 14236-81. These are: strength, elongation and specific breaking work of films. The optimal heat treatment mode of the nanocomposite was determined during the active experiment according to the second order V2 plan. It has been found that the dependence of strength and deformation on the content of the nanoscale filler has the form of a quadratic function with an extremum in the form of a maximum. The maximum strength of 21.64 MPa and the relative deformation of 2.4 have nanocomposite samples at a fill volume of 0.02. With a further increase in the content of filler, the strength and deformation of the nanocomposite samples decrease to 19.2 MPa and 2.03, respectively. The decrease in strength can be explained by aggregation of filler nanoparticles. The optimal composition of the F-40S elastomer-based nanocomposite was determined, providing the highest mechanical properties of the material: elastomer F-40S - 100 parts by weight, aluminum nanopowder - 0.075 parts by weight. Based on the results of the multifactorial experiment, a regression model of the dependence of the specific destruction work of the nanocomposite films on the temperature and time of thermal treatment by a convective method was obtained. The optimal mode of convective heating of the elastomeric nanocomposite was determined: temperature 40.0 0S, time 3.0 hours, at which the material films have the highest specific fracture operation of 52.0 MJ/m3.

The high-quality implementation of the technological process of harvesting potatoes largely depends on the separation process. A separating elevator with cleaning rubber-coated blades is proposed in order to improve the process of separation of the soil-tuberous mass and reduce damage to tubers. The conveyor with rubber blades is located inside the main and moving against the direction of the separating elevator movement. Mounted blades with their touch will clean the lumens of the rods from sticking. The quality of the completeness of the separation of potato harvesters depends on the duration of the presence of the soil-tuberous mass on the working surface of the elevator. In the course of theoretical studies, the relative speed of movement of the soil-tuberous mass was analytically determined depending on the change in the mass of the soil layer after the interaction of the blades of the internal conveyor with the elevator bars. The range of change in the rational value of the elevator speed for elliptical shakers was taken into account. The graphs of the dependences of the relative speed of movement of the soil-tuberous mass on the kinematic parameters of the internal conveyor and on the congestion of the elevator are analyzed. It has been established that the interaction of the blades of the internal conveyor with the bars of the elevator has little effect on the speed of the soil layer. The internal conveyor with rubberized blades will clean the gaps between the bars of the elevator without resisting the movement of soil and tuber mass on the surface of the separating elevator, thereby improving the quality of soil separation and reducing damage to tubers.
