Moral, diferença e currículo: diálogos entre Nietzsche, Deleuze e a educação
Authors: Dos Santos Amarildo Inácio , Gomes Brito de Sá Maria Roseli , Farias Freire Raic Daniele
Published: September 2022

Este artigo visa estabelecer um diálogo entre Nietzsche, Deleuze e a educação. Para isso são estabelecidas e problematizadas algumas relações entre as concepções teóricas de moral de negação, desenvolvida por Nietzsche; Diferença, formulada por Deleuze e a abordagem pós-crítica dos estudos curriculares. O objetivo perseguido neste trabalho foi problematizar ressonâncias da moral judaico-cristã na relação educação-Diferença e possíveis efeitos de poder decorrentes disso. Com base em aporte teórico de enquadramento epistemológico pós-estruturalista, argumenta-se que a moral de negação atravessa os currículos escolares. Em função disso, os currículos assumem determinadas identidades como essências tomando-as como modelos nos processos de subjetivação. Por privilegiar a produção de identidades, os currículos não concebem a Diferença em si mesma, sem referente. Apenas a concebem como diferença em relação a, como variação de identidades naturalizadas que privilegiam e tentam reproduzir. A partir de Deleuze propõe-se pensar os currículos na perspectiva da Diferença. Currículos pensados por essas lentes teóricas não assumem passivamente a moral de negação e a identidade como verdades fundantes e absolutas, mas as colocam em questão enquanto defendem uma moral afirmativa que cria e recria a si dando vazão à Diferença em si mesma. Currículos assim constituídos não buscam homogeneizar os indivíduos, mas aumentar sua potência de agir e afirmar-se como singularidades em processos constantes de construção-desconstrução-reconstrução.
Mecanismos de incentivos tarifários para microgeração fotovoltaica por meio de gerenciamento de carga pelo lado da demanda
Authors: Ribeiro da Costa André , Cesar Marques Carvalho Paulo
Published: September 2022

O crescimento da inserção de microgeração fotovoltaica (FV) nas redes de distribuição tem sido alavancada por importantes mudanças na regulamentação e incentivos na expansão dessa modalidade no setor elétrico nacional e internacional. No caso do Brasil, o amplo território e o excelente nível de irradiação solar colocam o país em vantagem em termos de recursos a nível mundial. Entretanto, o país possui ainda um enorme potencial energético inexplorado, onde é possível perceber claramente a subutilização desses recursos. Existem países com regiões menos favorecidas em termos de irradiação solar, mas que possuem uma capacidade instalada de geração FV muito superior, apresentando uma parcela considerável de geração renovável na matriz elétrica. Diversos programas de incentivos têm sido criados em vários países no sentido de impulsionar a indústria de microgeração a obter a escala necessária para competir com outras fontes de energia elétrica, buscando a independência tecnológica e a diminuição das emissões de gases de efeito estufa no planeta. Contudo, com o maior uso das instalações de geração FV, surge a preocupação sobre o impacto nos sistemas de distribuição e transmissão de energia, no que se refere à divergência entre os períodos de geração e os períodos de pico de demanda, principalmente para consumidores residenciais. O uso do gerenciamento de energia pelo lado da demanda (GLD) associada às políticas de incentivos tarifários tendem a favorecer financeiramente a fatura de energia do consumidor e auxiliar na mitigação do pico de demanda de energia no sistema elétrico. Assim, a partir desta motivação, o presente artigo apresenta uma metodologia para a análise da viabilidade financeira na fatura de energia, utilizando as tarifas de energia elétrica vigentes no Brasil e combinando o sistema de geração FV com armazenamento de energia. O método proposto contempla base de dados reais de demanda de energia e geração, sugerindo que outras unidades de geração semelhantes possam se beneficiar da mesma análise e auxiliar na tomada de decisão; e, adicionalmente, podem utilizar a análise como forma de direcionar o incentivo à expansão dessa modalidade com base na escolha de tarifas diferenciadas.

The Effectiveness of Intermittent Pneumatic Compression for Delayed Onset Muscle Soreness in Active People: A Literature Review
Authors: Vida Nanda Chattalia  , Ni Nyoman Mekar Sari
Published: September 2022

Introduction: When the exercises we perform exceed the muscle endurance threshold, Delayed Onset Muscle Soreness (DOMS) often occurs. DOMS is pain that a person feels 24 to 48 hours after strenuous physical activity or heavy and intense physical activity that can lead to damage to muscles and other connective tissues in the form of small tears in the muscles, muscle spasms, overstretching, and can cause tendon and connective tissue tears. Symptoms produced by DOMS conditions are certainly alarming for daily activities. This literature review will discuss ways to reduce DOMS conditions by using Intermittent Pneumatic Compression to overcome these conditions.

Methods: The method in this study used a literature review based on the study results of data sources (including PubMed, ScienceDirect, NCBI, and Google Scholar) database with a publication period from 2017 to 2022. Keywords used in the search: [“Delayed Onset Muscle Soreness,” “DOMS” or “Muscle Soreness”] and [“Intermittent Pneumatic Compression” or “Recovery Pump”].

Results: We found three related articles: two randomized controlled trials and one cross-over design based on the search result. The studies examined the effectiveness of Intermittent Pneumatic Compression on Delayed Onset Muscle Soreness. In the results of the three studies, Intermittent Pneumatic Compression offered little to no benefit in the recovery of DOMS inactive people.

Conclusion: All studies concluded Intermittent Pneumatic Compression was not effective in reducing Delayed Onset Muscle Soreness.
Indonesian Version of the Anterior Cruciate Ligament-Return to Sport After Injury Questionnaire Through Cross-Cultural Adaptation, Validity, and Reliability Testing
Authors: Ihsan Muammar , Wibawa Ari , Muliarta I Made , Tianing Ni Wayan
Published: September 2022

Background: This study aimed to produce the Indonesian version of the Anterior Cruciate Ligament-Return to Sport After Injury (ACL-RSI) questionnaire and determine the value of content validity, construct validity, known-groups validity, and internal consistency reliability.

Methods: First, the ACL-RSI questionnaire was translated through a cross-cultural adaptation process. Six experts in related fields assessed the adapted questionnaire by giving scores on four criteria: relevance, clarity, simplicity, and ambiguity, which will be calculated into content validity value. Seventy-one participants who experienced ACL injury because of sporting activities and had undergone reconstruction who joined the online community for Knee Injury Patients Support Group filled out the ACL-RSI to determine the known-groups validity and internal consistency reliability. The participants also filled out the Indonesian version of the Knee Injury and Osteoarthritis Outcome Score (KOOS) as a comparison to test construct validity.

Results: The calculated content validity value obtained from the experts’ scoring was S-CVI/Ave = 0.97. Construct validity between ACL-RSI and all KOOS subscales showed a strong positive correlation with r = 0.78-0.87. Two hypotheses for known-groups validity were proven, with the group that had returned to their specific sport having a better ACL-RSI score than the group that had not returned (70.2 ± 10.0 vs. 49.3 ± 18.8, p<0.001), and the group planned to return to their specific sport as before the injury had a better ACL-RSI score than the group who did not intend to return (60.3 ± 16.5 vs. 32.6 ± 2.4, p<0.001). Internal consistency ACL-RSI showed very good reliability with Cronbach’s alpha = 0.96.

Conclusions: The Indonesian version of ACL-RSI is valid and reliable for evaluating psychological readiness to return to sports after ACL reconstruction. However, a seemingly further similar study is necessary to fix the weaknesses in this study to produce a more representative Indonesian version of the ACL-RSI questionnaire.
Câhiliye Dönemi Arap Şiirinde Korku Kaynakları ve Korku İfade Eden Sözcükler

Published: September 2022

Çalışmamızın konusunu Câhiliye dönemi Arap şiirinde korku ve temel korku kaynakları oluşturmaktadır. İnsan psikolojisinin önemli unsurlarından biri olan korkunun Câhiliye dönemi şairleri tarafından şiirlerinde dile getirilmesi ve dizelerde korkunun değişik yönlerini, şiddetini ifade eden farklı kelimelerin kullanılması çalışmada ele alınmıştır. Güvenliği sağlayacak bir devlet düzeni ve adalet sistemini işletecek genel bir kolluk gücünün bulunmayışı sebebiyle Arabîstan yarımadasında gerek sınırlı sayıda şehirde yerleşik gerekse göçebe kabileler halinde sürdürülen yaşam doğal bir korku iklimi oluşturmuştur. Su ve yiyecek kaynaklarının son derece kıt olduğu çöl hayatı, güçlülerin zayıfları ezdiği bir sistemi ortaya çıkarmış, baskın yapılarak mağlupların katli veya köleleştirilmesi, namuslarına el uzatılması, onur ve haysiyetlerinin yerle yeksan edilmesi korkuyu besleyen ögeler olmuştur. Kendisiyle ensâbın muhafaza olunduğu, kahramanlıkların bilindiği, dilin kendisinden öğrenildiği Arapların “Dîvânı” sayılan şiirlerin bu önemli psikolojik olguya yer vermemeleri, enine boyuna incelememeleri ve korkuyla ilgili uzak-yakın kelimeleri ihtiva etmemeleri düşünülemezdi. Yazının yaygın olmaması sebebiyle sosyal hayatı en iyi yansıtan edebi eserin şiir olması hasebiyle şiirlerde yer alan korku anlamına gelen kelimeler çalışmamızda incelendi. Araştırmamızı Câhiliye dönemi ile sınırlı tutmakla birlikte edebi hayatlarının bir kısmı cahiliye döneminde geçmiş olan Muhadram şairlerin şiirlerinden örnekler de verildi.

Published: September 2022

Cysts of maxillary sinuses in both children and adults haven’t specific clinical manifestations and are often findings on CT or MRI and have an odontogenic or non­odontogenic origin. Systematized data of the prevalence and flow characteristics of this pathology in children are insufficient. Objectives: clinical and epidemiological analysis of cystic maxillary sinusitis in children. Material and methods: data of 42 patients of the children’s ENT­department who were operated for non­odontogenic cysts of maxillary sinuses. Results. Age of group patients in which the studied pathology was diagnosed most frequently was 10–17 years old. Correlation of the cysts of maxillary sinus with pathology of the nasal cavity and nasopharynx were analyzed: septal deviation (68 %), rhinitis (42 %), adenoids (10 %), anthroanal polyp (25 %) was noted. Pathomorphological examination of the material obtained at endoscopic removal of cysts presence of inflammatory in 78 % of biopsy. Conclusion. In most cases a patient with a cyst of maxillary sinus is subject to dynamic observation by an otorhinolaryngologist and endoscopic examination of the nasal cavity is an essential element for timely detection of pathology of the ostiomeatal complex or choanal polyp accompanying the cyst development.

The interaction between the growing cases of eating disorders and schizophrenia spectrum disorders is a complex area that has received little attention. Its study raises conceptual and methodological questions in both areas of psychiatry with the aim of timely diagnosis and treatment of patients with anorexia syndrome. The aim of the work is to discuss the possible differences in the outcomes of inpatient treatment of people with eating disorders, depending on the true nosological affiliation of the anorexia syndrome and, accordingly, associated with different times of psychopharmacological interventions. The authors describe two clinical cases of patients with deviant eating behavior, demonstrating the exceptional importance of an integrative assessment of the anorexia syndrome in the psychiatrist’s work (on the example of using the method of differential diagnosis of eating disorders and schizophrenia in psychiatric hospitals).

Over the past two years, COVID­19 has continued to be a worldwide problem. Large­scale vaccination of the population is aimed at achieving herd immunity. The presence of 80 % or more immune people in the population should lead to the end of the pandemic with the least human losses. The purpose of the study: to assess the impact of vaccination on the incidence of COVID­19 infection among students of the medical faculty of the Belarusian State Medical University. Information on cases of COVID­19 infection among students (total sample N = 351 people) from the beginning of 2020 to December 31, 2021, as well as data on specific prophylaxis with various vaccine options, were obtained. In the group of unvaccinated students, 46,15 % were ill with COVID­19 infection; among vaccinated students (n = 249 people), 9,24 % had COVID­19 infection after vaccination – as of December 31, 2021. A comparative analysis did not reveal significant differences in efficacy between the two most commonly used vaccines in 2021 in the Republic of Belarus – Sputnik V (Gam­COVID­Vak) and Vero Cell (Sinopharm). After the achievement of herd immunity (as of November 1, 2021, the pool of conditionally immune students reached 79,20 % of the total sample), only isolated cases of the disease were registered in November and December 2021.

Infectious mononucleosis at various stages of the pathological process and depending on the severity, presence of complications is characterized by polymorphism of the clinical features, which greatly complicates its early diagnosis. Features of the course, clinical manifestations of acute infectious mononucleosis in 55 children and adolescents aged 1 to 14 years, at various stages of the diagnostic process were analyzed. Common combination of clinical syndromes, which allows to suspect the presence of infectious mononucleosis, were identified. To establish the diagnosis of infectious mononucleosis, an integrated approach is required, taking into account the dynamics of the disease during the first week of the disease, the data of laboratory and instrumental studies. Infectious mononucleosis is distinguished by the polymorphism of the clinical picture, depending on the prevalence of general inflammatory syndrome, endotoxicosis syndrome, lymphoproliferative, hepatolienal and other syndromes, as well as its complicated and uncomplicated course. Most often at the prehospital stage, the “masks” of MI were: acute respiratory viral infection (43.8 ± 7.16 %), acute allergic reaction (35.4 ± 6.9 %), acute community­acquired pneumonia (16.7 ± 5.38 % of cases), follicular and lacunar tonsillitis (8.3 ± 3.98 %). Diagnosis of MI is also difficult due to the rather late (on the second week of the disease) appearance of atypical mononuclear cells in the peripheral blood of patients, with a parallel long­term absence of clinical symptoms sufficient for the diagnosis of infectious mononucleosis in 41.7 ± 7.12 % of patients.
Typhoon-associated air quality over the Guangdong–Hong Kong–Macao Greater Bay Area, China: machine learning-based prediction and assessment
Authors: Chen Yilin , Yang Yuanjian , Gao Meng
Published: September 2022

Abstract. The summertime air pollution events endangering public health in the Guangdong–Hong Kong–Macao Greater Bay Area are connected with typhoons. The wind of the typhoon periphery results in poor diffusion conditions and favorable conditions for transboundary air pollution. Random Forest models are established to predict typhoon-associated air quality in the area. The correlation coefficients and the root-mean-square errors of the air quality index (AQI) and PM2.5, PM10, SO2, NO2 and O3 concentrations are 0.84 (14.88), 0.86 (10.31 µg/m3), 0.84 (17.03 µg/m3), 0.51 (8.13 µg/m3), 0.80 (13.64 µg/m3) and 0.89 (22.43 µg/m3), respectively. Additionally, the prediction models for non-typhoon days are established. According to the feature importance output of the models, the differences in the meteorological drivers of typhoon days and non-typhoon days are revealed. On typhoon days, the air quality is dominated by local source emission and accumulation as the sink of pollutants reduces significantly under stagnant weather, while by the transportation and scavenging effect of sea breeze on non-typhoon days. Therefore, our findings suggest that different air pollution control strategies for typhoon days and non-typhoon days should be proposed.

Published: September 2022

Abstract. Since 2000, and for the following 20 years, hydrological
data of the Mediterranean Sea, with a particular focus on the western and
central Mediterranean sub-basins, have been acquired to study the
hydrodynamics at both coastal and open sea scales. In total, 1468 hydrological casts were realized in 29 oceanographic cruises planned due to scientific purposes linked with funding research projects but were also sometimes driven by sea conditions and type of vessel. After accurate quality assurance and control, following standard procedures, all hydrological data were included in four online public open-access repositories in SEANOE (SEA scieNtific Open data Edition), available from https://doi.org/10.17882/87567 (Ribotti et al., 2022). Hydrological and
dissolved oxygen data are always present in all of the datasets, whereas pH, fluorescence, turbidity, and chromophoric dissolved organic matter (CDOM) are available just for some cruises. Samplings were carried out mainly along transects, with some repetition over the years. The results of two data analyses, i.e., staircase systems in the Tyrrhenian Sea and in the Algero-Provençal sub-basin and spreading of the Western Mediterranean Transient, are mentioned.
The precision of satellite-based irrigation quantification in the Indus and Ganges basins
Authors: Kragh Søren Julsgaard , Fensholt Rasmus , Stisen Simon , Koch Julian
Published: September 2022

Abstract. Even though irrigation is the largest direct anthropogenic interference with the terrestrial water cycle, limited knowledge on the amount of water applied for irrigation exist. Quantification of irrigation via evapotranspiration (ET) or soil moisture residuals between remote sensing models and hydrological models, with the latter acting as baselines of natural conditions without the influence of irrigation, have successfully been applied in various regions. Here, we implement an novel ensemble methodology to estimate the precision of ET-based net irrigation quantification by combining different ET and precipitation products in the Indus and Ganges basins. A multi-model calibration of 15 models independently calibrated to simulate natural rainfed ET was conducted prior to the irrigation quantification. Based on the ensemble average, the 2003–2013 net irrigation amounts to 246 mm/year (78 km3/year) and 115 mm/year (76 km3/year) in Indus and Ganges basin, respectively. Net irrigation in Indus basin is evenly split between dry and wet period, whereas 73 % of net irrigation occurs during the dry period in Ganges basin. We found that although annual ET from remote sensing models varied by 91.5 mm/year, net irrigation precision was within 25 mm/season during the dry period, which emphasizes the robustness the applied multi-model calibration approach. Net irrigation variance was found to decrease as ET uncertainty decreased, which related to the climatic conditions, i.e. high uncertainty under arid conditions. A variance decomposition analysis showed that ET uncertainty accounted for 81 % of the overall net irrigation variance and that the influence of precipitation uncertainty was seasonally dependent, i.e. with an increase during the monsoon season. The results underline the robustness of the framework to support large scale sustainable water resource management of irrigated land.
Effects of dynamic changes of desiccation cracks on preferential flow: Experimental investigation and numerical modeling

Published: September 2022

Abstract. Preferential flow induced by desiccation cracks (PF-DC) has been proven to be an important hydrological effect that could cause various geotechnical engineering and ecological environment problems. Investigation on the PF-DC remains a great challenge due to the soil shrinking-swelling behavior. This work presents an experimental and numerical study of the PF-DC considering the dynamic changes of DC. A soil column test was conducted under wetting-drying cycles to investigate the dynamic changes of DC and their hydrological response. The ratio between the crack area and soil matrix area (crack ratio), crack aperture and depth were measured. The soil water content, matrix suction and water drainage were monitored. A new dynamic dual-permeability preferential flow model (DPMDy) was developed, which includes physically-consistent functions in describing the variation of both porosity and hydraulic conductivity in crack and matrix domains. Its performance was compared to the single-domain model (SDM) and rigid dual-permeability model (DPM) with fixed crack ratio and hydraulic conductivity. The experimental results showed that the maximum crack ratio and aperture decreased when the evaporation intensity was excessively raised. The self-closure phenomenon of cracks and increased surficial water content were observed during low evaporation periods. The simulation results showed that the matrix evaporation modeled by the DPMDy is lower than that of the SDM and DPM, but its crack evaporation is the highest. Compared to the DPM, the DPMDy simulated a faster pressure head building-up process in the crack domain and higher water exchange rates from the crack to the matrix domain during rainfall. Using a fixed crack ratio in the DPM, whether it is the maximum or the average value from the experiment data, will overestimate the infiltration fluxes of PF-DC but underestimate its contribution to the matrix domain. In conclusion, the DPMDy better described the underlying physics involving crack evolution and hydrological response with respect to the SDM and DPM. Further improvement of the DPMDy should focus on the hysteresis effect of the SWRC curve and soil deformation during wetting-drying cycles.

Published: September 2022

Abstract. Flood risk to single-family rental housing remains poorly understood, leaving a large and increasing population underinformed to protect themselves, including regarding insurance. This research introduces a life-cycle benefit-cost analysis for the landlord, tenant, and insurer (i.e., National Flood Insurance Program (NFIP)) to optimize freeboard (i.e., additional first-floor height above the base flood elevation (BFE)) selection for a rental single-family home. Flood insurance premium; apportioned flood risk among the landlord, tenant, and NFIP by insurance coverage and deductible; rental loss; moving and displacement costs; freeboard construction cost; and rent increase upon freeboard implementation are considered in estimating net benefit (NB) by freeboard. For a 2,500 square-foot case study home in Metairie, Louisiana, a two-foot freeboard optimizes the combined savings for landlord and tenant, with joint life-cycle NB of $23,658 and $14,978, for a 3 % and 7 % real discount rate, respectively. Any freeboard up to 2.5 feet benefits the tenant and NFIP, while the landlord benefits for freeboards up to 4.0 feet. Collectively, results suggest that at the time of construction, even minimal freeboard provides substantial savings for the landlord, tenant, and NFIP. The research provides actionable information, supporting the decision-making process for landlords, tenants, and others, thereby enhancing investment and occupation decisions.
Scaling effects of fixed-wing ground-generation airborne wind energy systems

Published: September 2022

Abstract. While some airborne wind energy system (AWES) companies aim at small, temporary or remote off-grid markets, others aim at utility-scale, multi-megawatt integration into the electricity grid. This study investigates the scaling effects of single-wing, ground-generation AWESs from small- to utility-scale systems, subject to realistic 10 min, onshore and offshore wind conditions derived from a numerical mesoscale Weather Research And Forecasting (WRF) model. To reduce computational cost, vertical wind velocity profiles are grouped into 10 clusters using k-means clustering. Three representative profiles from each cluster are implemented into a nonlinear AWES optimal control model to determine power-optimal trajectories. We compare the effects of three different aircraft masses and two sets of nonlinear aerodynamic coefficients for aircraft with wing areas ranging from 10 to 150 m2 on operating parameters and flight trajectories. We predict size- and mass-dependent AWES power curves, annual energy production (AEP) and capacity factors (cf) and compare them to a quasi-steady-state reference model. Instantaneous force, tether-reeling speed and power fluctuations as well as power losses associated with tether drag and system mass are quantified.

Electrical energy is a very important requirement both now and in the future. The electrical energy that we use today still comes from conventional power plant. Conventional power plant will create many threats such as increasing pollution and decreasing fossil fuels. Problems like this will have a bad impact on the future. Utilization of alternative energy is one way to solve these problems. Around us there is a lot of energy that will have the potential for us to develop it into a source of electricity for our daily needs. This energy includes solar energy. The purpose of this research is to create and design a solar powered renewable energy teaching aid. The method used in this process is to collect data, then the design process of the props is carried out. Making props is an important factor in this research so that during the testing process the props do not experience significant obstacles. The design of this power plant aims to make teaching aids as a learning medium and to obtain maximum and more efficient energy quantity results. The props consist of several components, namely solar panels, controllers, inverters, volt ampere meters, batteries (accumulator), cables, lights and mini houses. These props are to show that solar energy can be used to generate electricity that can be used for home lighting purposes.
Influential choices: deconstructing operationalisations of Indigeneity in survey-based education research using an example from Peru
Authors: Broeks Miriam , Sabates Aysa Ricardo
Published: September 2022

Indigeneity is a complex social construct that can be defined in multiple ways using diverse markerstraditionally based on the characteristics of individuals. Survey-based studies have used language,self-identification or location information to operationalise Indigeneity. Yet, as suggested by Walterand Andersen (2013), Gillborn et al. (2018) and others, few scholars reflect on how the Indigeneityvariable is specified and whether this operationalisation may impact results. This article examinesthis issue empirically using the case of Indigeneity in Peru. First, survey-based empirical studies areidentified to explore the ways in which Indigeneity has been operationalised. Then, using the YoungLives study, we present diverse operationalisations of Indigeneity and outline how these may lead to different educational outcomes for children. We show that quantitative researchers using surveybased data should engage more deeply with different operationalisations of Indigeneity as these can lead to different educational outcomes for children categorised as Indigenous.

Published: September 2022

The largest school division in Winnipeg, Canada—the Winnipeg School Division—is undertaking several initiatives in the teaching for reconciliation and in meeting the educational mandate of the Truth and Reconciliation Commission of Canada’s 94 Calls to Action. These initiatives are being implemented in many of the division’s K-12 schools and a variety of subject areas. This articleexamines the reconciliatory initiatives that provide Indigenous and non-Indigenous learners alike with meaningful information about traditional practices and opportunities to engage in relationshipbuilding and cross-cultural understanding. The literature review section examines the historical and societal injustices perpetrated upon Indigenous peoples, newcomers’ needs around Indigenous issues, and the important role that Indigenous and non-Indigenous teachers have in the reconciliation process. The methodology section focuses on document analysis and its relevance as a research method. The article concludes with an examination of the potential and resistance of teaching for reconciliation in Canada.

Los objetivos centrales fueron la defensa y la legitimación del orden político del porfiriato y a su vez del proceso de conquista y colonización de México por parte de España, como una manera de combatir la creciente hispanofobia que se vivía en la sociedad mexicana. Los argumentos utilizados fueron las concepciones positivistas de la sociedad y una visión evolucionista que encontraba sus justificaciones en el contexto histórico y en la supervivencia del “más apto”, marcando la distinción para el caso español, en donde se protegió a la población indígena de su “destino inexorable”. que era su desaparición y exterminio ante las “razas más fuertes”.
El periodismo español en la Ciudad de México al servicio de la pax porfiriana (1884-1892)
Authors: Gutiérrez Domínguez María del Mar
Published: September 2022

El objetivo del artículo es explicar la evolución de la prensa española en la capital mexicana durante la primera y segunda reelección de Porfirio Díaz (1884-1888, 1888-1892), momento a partir del cual comenzó la consolidación de lo que posteriormente sería conocido como “Porfiriato”, un régimen preocupado por la pacificación del país y el desarrollo de las inversiones extranjeras. El periodismo español, que hasta el momento había permanecido bastante replegado sobre las preocupaciones de la colonia española, dio durante estos años un importante viraje. Así, al comenzar la última década del siglo XIX, el vocero más representativo de la colectividad —El Correo Español— era un periódico afín a la clase política en el poder y representante de un grupo que tenía numerosas concesiones y contratos comerciales con el gobierno.
Los soldados de la “civilización” en los orígenes del modelo militar roquista. Argentina, 1878-1880

Published: September 2022

En este trabajo vamos a analizar las prácticas orientadas a la renovación de las estructuras militares y el discurso político asociado a ellas en el momento de la aparición política de Julio Roca al frente del ministerio de guerra y marina. En el breve espacio temporal situado en el cambio de las décadas del 70 al 80 del siglo XIX, se suceden una serie de acontecimientos que modifican el mapa físico, político e institucional de la República Argentina, cristalizando algunas de las formas de Estado y estilos de repúblicas que estuvieron en disputa durante aquellos años. Nos interesa examinar la política militar impulsada desde el gobierno nacional a partir de que Julio Roca asume el ministerio de guerra al comenzar el año 1878, desde una perspectiva que permita vislumbrar el rol de las fuerzas militares (Guardia Nacional-Ejército de Línea) en el proceso de avance estatal hacia el sur del territorio y nos ayude a comprender el papel asignado a los miembros subalternos de las fuerzas armadas en esa empresa.
Methodology for calculating the pasta dough flow parameters in stepped cylindrical channels

Published: September 2022

The introduction provides information about the state of the problem and substantiates the relevance of the research. The purpose of the work is to develop a methodology for calculating the relationship between pressure losses during the flow of pasta dough in channels with a stepped-variable cross section with the dimensions of the channel structural, as well as with the pasta dough rheological properties and the performance of device. In the methodological part of the work, the applied rheological model is described and a technique for mathematical modeling of power and kinematic parameters of pasta dough flow in stepped cylindrical channels is given. Due to the small contribution of the pasta dough shear strength to the total pressure loss, a rheological model of a non-linear-viscous medium is used, which is described by the power – law rheological Ostwald–de Waele equation. Neglecting the elastic deformations of the dough and the elastic change in volume, we assumed the condition of constancy of the volume and mass flow (productivity) for any cross section of the channel in each of its sections. In the main part of the work, analytical dependencies are presented that relate the magnitude of the pressure drop to overcome viscous resistance during the flow of pasta dough in channels with a stepped-variable cross section with the dimensions of the structural elements of the channel, as well as with the rheological properties of the pasta dough and the performance of the device. These dependences formed the theoretical basis  for calculating method of the pasta dough flow parameters in stepped cylindrical channels. The technique  was tested on the example of an industrial macaroni press matrix equipped with a system of stepped-variable channels in the pre-forming zone. The results of the research can be used in the design of new sizes of matrices for pasta dough molding as well as in the educational process in the training of food production process engineers.
Analysis of existing applications of the biopolymer chitin and its derivatives
Authors: Klishanets E. T.
Published: September 2022

The introduction presents scientific data on the structure, chemical composition and properties      of chitin, chitosan and the chitin-glucan complex. In recent years, special attention has been paid to the biopolymer chitin and its derivatives. Due to their unique properties: biocompatibility, biodegradability, non-toxicity,  they have found application in more than 70 areas: medicine, ecology, food industry, agriculture. Sources for the production of chitin can be the shell of commercial crustaceans, the biomass of fungi, and the cuticle of insects. The main part describes the modern fields of application of these biopolymers and raw materials for the production of chitin and its derivatives. At present, interest has increased in the problems of more rational use of renewable natural resources, both from an environmental and economic point of view. There are various biopolymers    in the world, in particular, the biopolymer of the 21st century – chitin and its derivatives. The recommended daily intake of chitin is from 3 to 7 g. The consumption of such an amount of chitin or chitosan is used to remove toxins and harmful substances, radionuclides, and pathogenic microorganisms from the body. On the industrial scale of the Republic of Belarus, fungi, insect carrion, earthworms can serve to isolate chitin and its derivatives. Due to the fact that on the industrial scale of the Republic of Belarus, the use of crustaceans as a source of chitin for the Republic of Belarus is very costly. In addition, a negative factor is the increase in pollution of sinks with heavy metals and other toxic waste.

Antibiotics play a huge role in poultry production as they are used to treat clinical diseases, to prevent and control common diseases and to enhance animal growth. However, misuse of antibiotics over time has led to the development of antimicrobial resistance in both animals and humans. Therefore, antibiotic free production of poultry has been on an increase in line with consumers’ preference for the same. However, a ban on antibiotics places a heavy burden on disease control and production costs of poultry. It also creates a need for alternatives whereby major companies have developed products like probiotics and essential oils in order to reduce the need for antibiotics in poultry production. The aim of this review is to highlight the journey towards antibiotic-free poultry production, role of antibiotics in the development of resistance, challenges encountered and alternatives used in antibiotic free production. In conclusion, this article recommends that antibiotics should not be completely banned due to poultry welfare issues. However, antibiotics should be used by trained personnel to only treat and control diseases.

Global growth is predicted to reach about 10 billion people in 2050 and 66% of this population will be concentrated in urban areas. As the world population, the need for food and feed for livestock is also increasing [1]. However, due to climate change, urbanization, and water scarcity, it is becoming difficult to improve the conditions of agricultural production for better yields. Therefore, traditional farming seems unable to maximize the quality and amount of produced crops [2]. Hydroponic is a great alternative for feed scarcity, it involves producing green fodder without soil in a closed environment and harvested after a short period 6-10days. This technology is gaining importance as it can guarantee a continuous and high yield of green forage around the year for livestock feeding. Seed in hydroponic cultivation can be the most important input and compared to the conventional system can present more than 80% of the total cost [3]. Livestock farmers can proceed with small- or large-scale hydroponic production systems using low-cost or high-tech devices for sustainable and profitable livestock production. In this study, we aim to explain six types of hydroponic systems based on plant nutrient supply technology: Wicking system, deep water culture DWC, drip system, aeroponics; ebb and flow system and nutrient film technique (NFT). In addition, we will review the advantages and disadvantages of hydroponic fodder production system and its hi-tech or low-cost applications.
