Published: September 2021

Abnormalities with processing social concepts as children may display with Autism Spectrum Disorder (ASD) and Nonverbal learning disorder (NSLD). The purpose of the study was to observe how children with disabilities and nondisabled children viewed gender stereotypes. Images of gender-advertised toys and clothing items were utilized to determine gender-biases held by preschoolers (ages 3-6), upper-elementary level students (ages 10-12), and high school level students (ages 15-18). This project raises awareness of cultural stereotypes in society and their impact on childhood perception development. 177 students were shown images of gender-advertised clothing and entertainment items and asked to categorize each object as a boy, girl, or both. Students with disabilities had less gender bias compared to their nondisabled counterparts. The children in all groups had increased stereotyped responses to clothing items as opposed to toys. The preschoolers displayed the most stereotypical responses, the upper-elementary schoolers responded with the least biased responses as they had gained more exposure to toy and clothing options, and the highschoolers solidified their opinions with moderate stereotypes, notably in clothing items. Presenting increased non-stereotypical opinions, there was a significant difference in gender perception in students with disabilities. The difference in responses to gender perception between students with and without disabilities assimilated in all categories by high school age, meaning there was no significant difference in gender perception by this stage.

Desde dezembro de 2019, o coronavírus da síndrome respiratória aguda grave 2 (SARS-Cov-2), inicialmente identificado na cidade chinesa de Wuhan, vem se disseminando rapidamente por todo o mundo, sendo responsável pela pandemia em curso, cuja dimensão já superou 33.000.000 casos confirmados e 995.000 mortes1 . A gravidade da doença pelo coronavírus 19 (Covid-19) varia de infecção subclínica a condições graves, com necessidade de internação em unidade intensiva, e cuja taxa de letalidade oscila entre 1-7%2 . Apresenta também um espectro clínico bastante rico, representado principalmente por sintomas relacionados ao trato respiratório, no entanto, devido à extensa expressão e distribuição da enzima de conversão da angiotensina 2 (ECA2) no organismo humano, a qual atua como receptor capaz de permitir a entrada do vírus nas células humanas, a Covid-19 pode ser considerada uma doença multiorgânica. A ECA2 está presente nas células epiteliais biliares e hepáticas, tornando o fígado alvo potencial para esta infecção. Estudo recente avaliou a expressão da ECA2 no pâncreas e concluiu que sua concentração era ainda maior do que nos pulmões, indicando que o SARS-CoV-2 também pode se ligar a este receptor no sítio pancreático, causando lesão3 . As anormalidades pancreáticas descritas na literatura incluem não somente a elevação assintomática de amilase e/ou lipase, mas também episódios de pancreatite aguda, sendo mais prevalentes nas formas severas da Covid-194 .

The purpose of this work is creation of an interconnected numerical model of the magnetic and hydrodynamic fields of the ferrofluid sealer to analyze the effect of centrifugal forces during shaft rotation on the retained pressure drop. The set goal was achieved by selection of the necessary equations, boundary conditions, assumptions and properties concerning the ferrofluids when building a numerical model of the sealer gap in the Comsol Multiphysics simulation environment. The important results of the work were the obtained and analyzed distributions of the magnetic field and pressure field in the ferrofluid, the evaluation results of the of the effect of centrifugal forces arising during the shaft rotation, on the pressure drop held by the sealer. It was shown that with a shaft radius of up to 50 mm and speed up to 3000 rpm, the change in the retained pressure drop was insignificant, and it was up to 2 % of the values with a stationary shaft. Significant manifestation of centrifugal force for the investigated shaft radii began at 6000 rpm. It was shown that the decrease in the retained pressure drop with an increase in the working gap was associated with the decrease in the magnetic field gradient. The significance of the results consisted in the possibility of using the developed model for the study of the ferrofluid sealer gap processes. Comparison with the data obtained using the analytical formulas showed that the latter overestimated the retained pressure drop

The scope of the work was the study of the phase failure operating for the new FACT’s type phase-shifting device, intended for the flexible connection of AC power systems. The mathamatical model has been developed for conducting this study. The device contains the main phase-shifting transformer based on hexagon circuit with additional regulating autotransformer, this creates the possibility of circular regulation of phase shift angle between connected systems. The model includes two 6-winding three-legs transformers, for which two sets of parameters can be independently set based on the data for the short circuit and no-load modes. The data for the direct sequence parameters is usually provided by the transformer manufacturers, and the data for the zero sequence parameters could be obtained upon additional request. As a result of modeling, the vectors of the voltages and currents were obtained in all windings in the investigated modes with supply source phase failure. This makes it possible to analyze the admissibility of such modes and estimate the need for taking special measures of protection against them. It is shown that the voltages on the windings of the main transformer insignificantly depend on the connection mode of the regulating autotransformer, while the pattern of currents distribution in the windings of the main and regulating transformers to a large extent is determined by said connection mode of the autotransformer. The presence of perceptible zero-sequence current flowing through the grounded neutrals of the power supply source and load is noticed. This fact is connected with the release of insignificant magnetic flux from the magnetic circuit in the surrounding space

The problem under consideration deals with the Stefan problems. Its most significant feature is the jump in the phase properties at separation of their moving boundaries. The objective was achieved by solving the following tasks: the construction of the process mathematical model based on its cell representation and with the use of the Markov chain theory mathematical apparatus, performing numerical experiments with the developed model, demonstrating its operability and the possibility to achieve the set goal. The most significant scientific results were as follows. First was an algorithm for the construction of a cell mathematical model of nonlinear thermal conductivity in a phase transitions medium with a moving phase interface for domains of a canonical shape (plane wall, cylinder, ball). Second, the results of the numerical experiments, showing that the jump of properties affected greatly the kinetics of the process. The significance of the results obtained consisted in the development of a simple but informative mathematical model of the media heat treatment kinetics with phase transformations, available for a direct use in the engineering practice. The proposed algorithm for constructing the model can be effectively used in prediction the open water pipes freezing in cold regions, in modeling the heat treatment of metals, in choosing the freezing modes of food products for a long-term storage, and other thermo-physical processes.

The aim of this work is to substantiate the possibility of increasing the technical, economic and environmental efficiency, as well as the efficiency of boilers (in terms of the intensity of corrosion processes) when burning water-fuel emulsions with the increased water and salt contents. To achieve these goals complex experimental studies were performed on the combustion of fuel oil and emulsions based on it, as well as the corrosion processes with a water content in the range from 2 to 30%, and a salt content ranging from 17 to 490 mg/dm3 hydrodynamic homogenizer. A significant result of the studies carried out is that with a water content of ~30% in the fuel gases composition, an NO2:NO ratio of 0,33 was achieved. That increased the absorption properties of gases and allowed passivation of carbon steel in sulfuric acid condensate. It also decreased the intensity of the low-temperature corrosion in the range of metal temperature of 130...70°C. All these made it possible to use condensation surfaces and to reduce the flue gases temperatures, to increase the efficiency of boilers, to ensure the economy of pure fuel, to increase the depth of utilization of the exhaust gases heat, and to reduce the concentration of toxic gases. The results obtained differed from those known. The significance of the results obtained lies in the fact that a technology was developed for the integrated use of the electrodialysis water resources, the waste and oil-containing waters, ensuring the operability of boilers, with a water content of emulsions of ~30% and a salt content of up to 450 mg/dm3.

Authors:   Odessa National Academy of Food Technologies, Ukraine, Burdo Oleg
Published: September 2021

The analysis of the Club of Rome global forecasting mode was carried out. A critical analysis of the Club of Rome activity was given. The purpose of the work is to establish the tasks of the food industry in solving the global problems of mankind. It is noted that the global crises (energy, ecology and food) are most clearly manifested in the food industry. To achieve this goal, a scientific and technical idea has been proposed that to solve the global problems the innovative technologies must be involved, which were not considered at all in the Club of Rome projects. The human development paradigm was formulated, considering the modern advances in science, technology, and nanotechnology. It was substantiated that the nanotechnology use in the food industry is attractive because the food raw materials are nano-sized structures created by nature. Local energy impact on nano-sized elements of the food raw materials can shorten the process time by the orders of magnitude. Such impacts are referred to as "nanoenergy technologies". The most significant result of the work was that the possibility was shown to control the development of the worst global crises by transferring the food industry onto the rails of the "nanoenergy technologies" and thus postpone the crises for another 10-40 years. The scientific significance of the obtained results was that such new effects as "barodiffusion" and "mechanodiffusion" were used in the work. The practical significance of the work was that a technological line for deep processing of food waste was proposed
Level of Engagement with Social Networking Services and Fear of Online Victimization: The Role of Online Victimization Experiences
Authors: Park Yeonjae , Vieraitis Lynne M.
Published: September 2021

Prior research indicates that fear of crime may lessen a person’s quality of life by leading them to avoid participating in social activities. The current study explores the relationship between fear of online victimization and participants’ levels of engagement with social networking services (SNS). Using data from a survey of 1,000 adolescents and adults aged 14 to 59 years, the direct relationship between the level of engagement on SNS and fear of online victimization and the indirect relationship through prior victimization were assessed. Findings show that the direct effect of the level of engagement on SNS on victimization experience was significant. In addition, the relationship between the level of engagement and the fear of victimization on SNS was significantly mediated through prior victimization experiences on SNS. These findings support the hypothesis that greater exposure on SNS increases online victimization, leading to a greater fear of victimization on SNS. Considering the large role SNS play in social activities and relationships, the findings are important for understanding how victimization impacts fear and may help inform policymakers how to help people stay engaged freely in socializing in a safer online environment.
Oficina Virtual de Construção de Tambor Afro-brasileiro:
Authors: MIRANDA JAIME RODRIGO DA SILVA
Published: September 2021

Este artigo discute a realização da Oficina Virtual de Construção de Tambores Afrobrasileiros como um processo arte-educativo de afirmação da ancestralidade africana em nosso país, ante um cenário político em que racismo e discriminação contra o povo negro ainda se constituem práticas cotidianas. Considerando que várias formas de opressão a afrodescendentes estão na base funcional de nossa estrutura social, aspectos ligados à ideologia da miscigenação e aspectos vinculados à hegemonia do cristianismo ocidental são problematizados em relação ao racismo institucional e estrutural da sociedade brasileira. Sendo o Brasil a maior população católica e segunda população cristã do planeta, a valorização da inter-religiosidade e das experiências não hegemônicas produzidas no chão da história se tornam relevantes instrumentos a favor de oprimidos, tendo-se nos princípios da Teologia Negra um patamar referencial. A ancestralidade espiritual e musical afro-brasileira é abordada como forte afirmação deste caminho decolonial, sobre o qual os tambores em suas várias formas e linguagens são vozes poderosas.  Por fim, traz-se uma descrição do processo artesanal de construção de um rústico instrumento percussivo e de sua conversão na oficina, em tempos estranhos de isolamento e intensificação de virtualidades.

A saúde coletiva se coloca como importante campo de pesquisas sobre violência, que propõe ações de prevenção e enfrentamento a esse determinante social de saúde. O presente artigo analisa como diversas expressões da violência têm sido historicamente debatidas e apresentadas nos relatórios das Conferências Nacionais de Saúde (CNS), espaço privilegiado de participação social para a definição de prioridades e diretrizes da Política. Para tanto, foi realizada uma análise documental dos relatórios das CNS a partir do ano 2000, quando se aprofundam as discussões sobre violência e saúde nesse espaço público. Os dados apontam para a crescente incorporação da temática, apresentada como uma das principais causas de mortalidade e morbidade da população brasileira. Em quase todos os relatórios, a violência foi colocada enquanto problema de saúde pública e progressivamente foram incorporados temas específicos com destaque para a violência contra mulher, a violência no contexto da saúde mental e a violência contra crianças e adolescentes.

El propósito de esta investigación es conocer y analizar los sentidos que los policías que se dedican al patrullaje en Montevideo construyen sobre las intervenciones policiales que involucran a jóvenes pobres. El trabajo fue planteado desde un abordaje metodológico cualitativo; más específicamente, la investigación fue realizada a través de entrevistas a policías. De esta forma, el trabajo presenta una novedad con respecto a los antecedentes a nivel nacional, ya que en Uruguay no existen investigaciones que aborden esta temática desde la percepción de los funcionarios policiales.

La formación policial es una instancia clave de socialización de los funcionarios policiales. Sin embargo, el proceso de aprendizaje de los policías excede al periodo de instrucción formal en la Escuela Nacional de Policía. Es en la praxis de su trabajo dónde incorporan algunas de las herramientas que utilizan cotidianamente. Por este motivo, para analizar las intervenciones policiales que involucran a jóvenes pobres intentaremos conocer los saberes que ponen en juego en las mismas.

Solid propellants are materials with controlled burning and one of the type used as fuel is solid propellant type composite, NH4ClO4 using as oxidizing agent and certain additives. Among them, stands out as CuCr2O4 accelerator burning (Shen, 1983; West, 1984; Meyer, 1987; Campos et al, 2010). Some of sites are activated by adsorption of reagents and because of this, increase the speed of decomposition of NH4ClO4 (Rastogi, 1978). In the present study, we performed the synthesis of compound CuCr2O4 by the methods of coprecipitation and ceramic, for the purpose of comparing structural differences, thermal and resulting morphological methods employed using the techniques XRD, FT-IR, TGA, DSC, SEM and density determination. The results show the best aspects to the compound synthesized by ceramic method, with higher crystallinity, thermal stability up to 1000°C and morphology more defined, with grains having geometries tetrahedral and octahedral and approximate size of 3750nm, very close to the literature, 3700nm (Smith and Snyder, 1969). However, the ceramic method becomes more expensive to use high purity raw materials, as well as use elevated temperatures for the synthesis of the product, which is used widely in manufacturing propellants for various purposes.

In this work the results of spectrophotometric assays performed on samples taken from the waters of ownership of organic products, located in the municipality of Paranaguá, as well as other physical and chemical testing of these samples are presented. They were conducted to evaluate the tissue property. The spectrophotometric assays were performed to quantify the chemical element phosphorus by the molybdenum blue method and nitrogen chemical element methods by Griess and Indophenol. These chemicals have low natural availability and macronutrients are important for the growth of plants. With the results it was found that the concentrations of the element nitrogen are below the limits specified by Resolution 357/2005 of CONAMA. Have phosphate ions showed higher concentrations in the water samples were taken from two specific points of organic property. In the samples from the first sampling point was observed that the levels of phosphate present were higher than the results obtained from samples taken from the second point, indicating that high phosphate concentration is likely due to high levels of soil phosphates and not an anthropic deposit held by the farmer. Thus it is concluded that the high concentration of phosphate ion is natural.

The objective of this study was to evaluate the ecotoxicological effect caused by the environmental impacts of mining in the river watershed Monkeys, under water and sediment, added to the physical-chemical studies conventional and quantification of metals in different seasons evaluated in two collections. The basin had severe degradation of evidence. Conventional parameters are not substantially altered, and no acute ecotoxicity in water. However the pellet is already at a high concentration of various metals, as well as chronic ecotoxicological effects. The occurrence of these chronic events, even in the face of normal physical-chemical results, shows the importance of these studies both in the water and sediment. The differences in the results of the two campaigns showed that the seasonally influenced the availability of organic matter in the sediment and / or adduced by leaching.

The search for alternatives for the treatment of industrial effluents, especially high toxicity is one of the main difficulties of the industrial treatment systems. This work aims to use potassium as a promoter of electrons for the oxidation to the catalyst by impregnating it MnO2/CeO2 to degrade the effluent coming from the processing of cashew nuts in the presence of oxygen. The experiments were performed in a slurry bed reactor. In the experiments were kept constant initial concentration in the effluent LCC (0.8 g/L), a major contaminant in the effluent of industrial activity, the stirring speed (900 rpm) and potassium impregnated percentage (1%). The operational parameters were: mass concentration of the catalyst (4.0 and 5.0 g/L), full system pressure (300 to 900 psi) and temperature (80-130°C). The tests showed that the composite K-MnO2/CeO2 demonstrates good activity as a catalyst in the process of wet oxidation of the effluent, reach levels above 90% removal. The best operating conditions found to perform the catalytic reaction of degradation of the effluent were: catalyst concentration of 5.0 g / L and 130ºC, having a pronounced effect on the pressure.

Copper is an essential trace nutrient for plants, animals. It is very essential at lower levels for specific metabolic functions, but is harmful at elevated levels. Significant amount of copper is widespread in the environment form variety of sources. A simple spectrophotometric method is presented for the determination of trace amounts of copper using salicyl salicyclic acid hydrazone (SSAH) as a spectrophotometric reagent. The proposed method has the advantages of sensitivity, rapidity and selectivity without any prior separation or extraction. The method was based on the reaction between SSAH and Cu(II) in acidic medium to produce a greenish-yellow colored complex. The complex has an absorption maximum at 420 nm. Beer’s law is obayed in the concentration range 0.2497 to 2.2471 μg mL−1. Several parameters like stability constant (1.13×107), molar absorption coefficient (8.560×104 L mol–1cm–1), Sandell’s sensitivity (0.0007 μg cm–2), linear calibration range, stoichiometry of the complex (1:1), method detection limit (0.0299 μg mL–1), limit of quantification (0.0598 μg mL–1), standard deviation (2.624%–3.567%) etc were calculated and presented. The effect of foreign ions on the determination was presented. The method was successfully applied for the determination of copper in spiked water samples and alloy samples.

A three-dimensional computer model of the topographic and anatomical variants of the lymph nodes in the axillary fossa gives reason to doubt the indisputability of the known data on the normal anatomy of the lymph nodes. This mainly concerns the presence of a lateral (shoulder) group of axillary lymph nodes (4-6 nodes), which can be located not only on the medial, but also on the posterior surface of the shoulder. In some cases, this group of axillary lymph nodes is generally absent in its typical place and is in close proximity to the central (intermediate) group of lymph nodes. Attention to the lateral (shoulder) group of lymph nodes is due to the fact that through them lymph drainage occurs from the entire superficial (epifascial) lymphatic system of the volar surface of the upper limb (skin and subcutaneous tissue). From the lateral group of lymph nodes, lymph drainage goes either to the central group or to the deltapectoral lymph nodes. In the course of axillary lymph node dissection of I, II and III levels in breast cancer, it is possible to save only the deltapectal lymph node with its afferent and efferent vessels, which provides full-fledged lymphatic drainage from the dorsolateral surface of the upper limb. But in this situation, without lymphatic drainage (superficial and deep) with preserved lymph production, the inner (volar) part of the upper limb remains, where lymphostasis begins to develop. An exception is the variant of localization of the brachial group of lymph nodes on the posterior surface of the shoulder, in which it is possible to preserve the lateral group of lymph nodes, which does not fall into the block of adipose tissue with other regional lymph nodes, and therefore partially preserve the lymph drainage from the medial surface of the ipsilateral upper limb towards the deltapectoral lymph node. Taking into account the topographic and anatomical variability of the lymph drainage collectors in the axillary fossa and the varied nature of the involvement of lymph nodes in the metastatic process, in each clinical case, the standard preoperative mapping of axillary lymph nodes (reverse lymphatic mapping) does not allow predicting the risk and timing of the development of postoperative upper limb lymphedema. The advantage of our technology two-contrast fluorescent lymphography - is the possibility of visual differentiation of all elements of lymph drainage from the mammary gland (indocyanine green - ICG) and the ipsilateral upper limb (methylene blue - MB). According to the results of the study, it will be possible to clarify the localization of the lateral (shoulder) group of axillary lymph nodes, topographic and anatomical features of the lymphatic drainage collectors in the axillary fossa and indications for lymphovenous shunting for primary surgical prevention of postmastectomy lymphedema of the upper limb.

This paper is a retrospective analysis of the long-term work of a large group of Russian scientists representing various Medical Institutions of St. Petersburg (in the past years of Leningrad) in the period from the 70s of the XX century to the present in the field of theoretical clinical lymphology. We aimed to discuss critical studies of a group of anatomists, in the sphere of the structure of lymphangions and lymph nodes in health and lymphedema of the lower extremities in humans. Experimental data of physiologists are presented, which made it possible for the first time to substantiate the functional mechanisms of active lymph transport in health and in lymphedema of the lower extremities. In addition, there are some results of testing biopsy specimens with various pharmacological agents and vasoactive substances. At last, there is an example of the clinical use of theoretical knowledge in the tactics of choice and expediency of surgical treatment of lymph drainage disorders in patients is given.
Generationsanklager – konflikt, følelser og ungdomsaktivisme

Published: September 2021

Compared to rhetorical defenses the rhetoric of accusations has not garnered much attention from rhetorical critics over time. Two common threads in existing approaches to accusatory rhetoric are a link to an underlying affirmative motive and a view of accusations as a rhetorical genre. However, these threads have not been fully developed so far. This article takes its point of departure in Carolyn Millers rhetorical theory of genre and Celeste Michelle Condit’s work with angry public rhetorics in order to reveal the social motive of the accusatory genre. The argument here is that the main motive can be found in a desire for corrective action, but is further supported by a definitory and moral motive. This is then used as a basis for treating generational accusations as a specific form of accusation as well as analyzing it in relation to Greta Thunberg’s rhetorical accusations of older generations in the climate change debate

This article studies the effects of the ambiguous accusations around Karl Ove Knausgaard’s novel in six parts, My struggle (2009-11). The novel’s portrait of a number of named individuals and family members brought the relationship between artistic freedom and defamation, responsibility, guilt and shame up for discussion, and initiated negotiations of collective norms and values in connection with autobiographical novels. An analysis of the rhetorical strategies behind the family’s accusations at the time of the publication, initially illuminates the ethical dilemmas the family helped to raise in the public debate. Next, the accusations in the novels themselves are studied and the article shows a need to consider how differently the accusations appear in and outside the novels, because the autobiographical novel establishes an ambiguous statement that is not found in the media coverage

The metoo-movement has sparked intense debate about the public accusations raised against named individuals for sexually transgressive behavior. A recurring point of ­discussion has been the timing, or rather the delay, of alle­gations, as many of them concern violations dating back ­decades. Through textual analysis of the affective-emotional dimensions of a charge presented in the form of a personal essay, this article reflects on the plausible reasons why victims may stay silent for years before speaking up. It suggests that some allegations must come with a delay, since the affected body may be in an epistemological crisis not allowing a robust narrative to be constructed, and, to present an allegation, a ­shared terminology for the nature of the offense is needed. Hence, the article explores conditions of possibility for the agency of abused bodies
