RESUMO Introdução: O Censo Brasileiro de Diálise (CBD) constitui importante fonte de dados nacionais sobre pessoas em diálise crônica que contribui para a formulação de políticas de saúde. Objetivo: Relatar dados epidemiológicos de 2021 do CBD da Sociedade Brasileira de Nefrologia (SBN). Métodos: Realizou-se pesquisa em centros brasileiros de diálise crônica utilizando questionário online abrangendo aspectos clínicos e epidemiológicos de pacientes em diálise crônica, dados sobre terapia dialítica, características dos centros de diálise e o impacto da pandemia COVID-19 em 2021. Resultados: Trinta por cento (n = 252) dos centros responderam ao questionário. Em Julho de 2021, o número total estimado de pacientes em diálise foi 148.363. As taxas estimadas de prevalência e incidência de pacientes por milhão da população (pmp) foram 696 e 224, respectivamente. Dos pacientes prevalentes, 94,2% estavam em hemodiálise (HD) (1,8% destes em hemodiafiltração), e 5,8% em diálise peritoneal (DP); 21% estavam na lista de espera para transplante. A taxa de incidência de COVID-19 confirmada entre Janeiro e Julho de 2021 foi 1.236/10.000 pacientes em diálise, e a taxa de letalidade atingiu 25,5%. Até Julho de 2021, 88,6% dos pacientes haviam recebido pelo menos uma dose da vacina anti-SARS-CoV-2. As taxas estimadas de mortalidade bruta anual geral e por COVID-19 foram de 22,3% e 5,3%, respectivamente. Conclusão: O número absoluto e a taxa de prevalência de pacientes em diálise crônica continuam aumentando. A maioria dos pacientes em diálise foram vacinados contra COVID-19 durante o ano. A pandemia COVID-19 contribuiu com a taxa de mortalidade geral.

Resumo Este artigo apresenta uma interpretação das práticas funerárias e pós-funerárias do sítio arqueológico Toca do Enoque, situado no Parque Nacional Serra das Confusões (Piauí, Brasil). As escavações arqueológicas possibilitaram a descoberta de três sepultamentos no local. Através de uma releitura dos contextos funerários escavados no sítio, foi possível propor a versão presumida dos processos de formação de cada depósito mortuário por meio de uma abordagem tafonômica. Dois sepultamentos eram individuais, o primeiro do tipo primário e não perturbado, enquanto o terceiro apresentou perturbações pós-deposicionais naturais e culturais. Ademais, o segundo sepultamento, uma ‘tumba de uso contínuo’ (ongoing tomb use) continha dez indivíduos e características complexas de formação, uso e reuso do depósito mortuário. As datações indiretas dos sepultamentos situam o uso funerário do abrigo por povos indígenas caçadores-coletores pré-ceramistas durante o Holoceno médio (c. 6.000-5.000 anos antes do presente).
Territorialidades e exercícios de autonomia: grupos sociais e moradia popular autoproduzida no Maranhão, Brasil
Authors: Burnett Frederico Lago , Souza Clara Raissa Pereira de , Moniz Filho Manoel Fernando
Published: November 2022

Resumo Apesar do quantitativo de moradias produzidas por inúmeros programas estatais, a prática da construção popular sem formalização ou participação de técnicos da área continua prevalecendo em todo o país como alternativa habitacional dos despossuídos. Resultado de pesquisa sobre moradia popular no Maranhão, este texto parte dos modos de vida das camadas populares rurais e urbanas do estado para demonstrar que, além de fornecerem abrigo e qualificarem espaços de vida, tais construções representam exercícios de autonomia e resistência social que enfrentam pressões sistêmicas variadas. Diferentemente dos procedimentos impositivos da política habitacional estatal, as decisões familiares para autoprodução da moradia estão intrinsecamente relacionadas com especificidades socioespaciais que caracterizam a arquitetura vernacular e, ao levarem em conta regime de posse da terra, estrutura familiar, práticas produtivas e acesso à renda, os construtores demonstram capacidade de concepção e gerenciamento na produção de seus espaços, aspectos a considerar nas análises acadêmicas e em parcerias profissionais, evitando criminalização e subordinação das práticas populares.

Resumo A tecnologia tem impactado o mundo de formas diversas. Assim, não é de surpreender que a Arqueologia e a Conservação-Restauração, nas últimas décadas, tenham experimentado mudanças no que diz respeito às teorias, metodologias e técnicas. Essas mudanças permitiram ‘novas’ possibilidades para, em certa medida, facilitar e aperfeiçoar as pesquisas e a preservação dos materiais recuperados; porém, ao mesmo tempo, é preciso lidar com os ‘novos’ problemas e desafios que as mudanças trazem. Na nossa perspectiva, como será evidenciado neste artigo, buscamos um equilíbrio entre esses extremos (os benefícios e os problemas das novas tecnologias), refletindo sobre os usos dessas tecnologias. Nós as entendemos como ferramentas que podem ser utilizadas no trabalho cotidiano, mas que, ao mesmo tempo, afetam diretamente a investigação; assim, em uma relação de natureza dialética, as novas tecnologias impactam as pesquisas e os pesquisadores. Para exemplificar essa discussão, serão apresentadas algumas reflexões teórico-metodológicas relativas à aplicação de tecnologia 3D em pesquisas, extensão, conservação-restauração no âmbito do projeto “Paisagens em branco: Arqueologia Antártica”, coordenado pelo Laboratório de Estudos Antárticos em Ciências Humanas da Universidade Federal de Minas Gerais (LEACH-UFMG).

Resumen Introducción Los estudios desde la perspectiva de género y los estudios feministas son aún emergentes en la Ciencia de la Ocupación. Desde el supuesto que habitamos una sociedad patriarcal, esta investigación rescata la narrativa de mujeres chilenas de mediana edad de la Región de Los Ríos, con el propósito de visibilizar cómo han construido sus vidas a partir de estereotipos de género que han determinado sus elecciones ocupacionales en función de las necesidades de los hombres, bajo un comprensión tradicional del binario femenino-masculino. Objetivo Reconocer y comprender la relación emergente entre los estereotipo de género, la construcción del cuerpo y las elecciones ocupacionales. Método Desde un posicionamiento posestructuralista feminista se realizan entrevistas con enfoque narrativo a una muestra intencionada de ocho mujeres; el análisis de discurso, como herramienta metodológica, da cuenta de la trayectoria de vida y experiencias de las mujeres en relación con el género, el cuerpo y las elecciones ocupacionales. Resultados De la investigación emergieron cinco categorías que reflejan la existencia de estereotipos de género en la construcción del cuerpo femenino que se impregnan en la identidad y elecciones ocupacionales a lo largo de su vida. Conclusión Las narrativas de las mujeres dan cuenta de la existencia de una relación dinámica emergente entre la construcción del cuerpo, estereotipos de género y elecciones ocupacionales, donde los estereotipos y el hacer se conjugan, generando una construcción del concepto mujer en un contexto socio histórico que define patrones y elecciones ocupacionales que replicarán estereotipos de género.
The Normative Emergence of Death in the Organization of American States’ Responses to COVID-19: towards a Regional Governance of Death
Authors: Marconi Cláudia A. , Santos Isabela Agostinelli dos , Miranda Rafael de Souza Nascimento
Published: November 2022

Abstract The COVID-19 pandemic has been (re)creating new global geographies of death, which specifically impact the Global South and expose its continuum of vulnerabilities – unequally distributed in terms of race, gender, class, and so on. In the Americas, we can identify the emergence of a new regional governance of death, associated with a set of practical recommendations by the Organization of American States (OAS) constraining states’ policy responses to COVID-19 and installing a new global governance lexicon. Recommendations concerning the disposal of dead bodies, full respect for both collective and family grief, and indications of alternative ways to conduct funerals and memorial services, for instance, seem to evoke new multilateral responses, paving the way for a new governance model: one that centres death within regional policymaking. This points to a change in the treatment of death from a purely private to a politically infused issue. Theoretically, this article aims to bridge the gap between Death Studies and Global Governance literatures. Supported by Michel Foucault’s genealogical method, the goal is to critically reconceptualise the meanings and framings of death landscapes in the Americas, pointing us to the correlation of forces that enabled the normative emergence of death in the OAS in this particular historical moment.
Pedagogical documentation in a formative experience in early childhood education: a look at the aesthetic principle
Authors: Pandini-Simiano Luciane , Lisboa Anna Carla Luz
Published: November 2022

Abstract This article discusses the pedagogical documentation and the aesthetic principles established in the guidelines of early childhood education. It aims to review to what extent the documenting path contributes to expanding sensitivity, the production of meanings and the possibilities of living together in early childhood education. The research, conducted in a qualitative perspective, stems from the following question: Does the documenting gesture make teachers aware of meeting and be together in early childhood education? The study carried out within the scope of a master’s degree in education had as sample a group of ten teachers who worked in early childhood education and who participated in a formative experience carried out in an extension course woven along the course of documenting. The survey instruments included participants’ observation, written, photographic and audiovisual records, documentation and, above all, being together with the teachers. From the dialogue between the normative guidelines and different authors, the aesthetic principle in the gesture of documenting is highlighted, because the encounter with the sensitive allows the expansion of borders, the possibility of affectation and the search for meanings and senses in the relationships woven between children and adults in everyday education. The training experience with teachers, built through the path of documenting, makes it possible to question assumptions naturalized in pedagogical practice, making important shifts in the ways of being and staying together in early childhood education.
The early childhood education offer in the private sector: a right or a business
Authors: Silva Denise Madeira de Castro e
Published: November 2022

Abstract This article analyzes the repercussions of the early childhood education offer in the private sector since the onset of the mandatory preschool in the city of Caxias do Sul, state of Rio Grande do Sul, Brazil, considering the implications of redefining the public and the private sectors. This research uses a qualitative approach on education, where 19 comprehensive interviews were conducted, which are considered at the same time a method and a technique. It also involves a documentary research. The discussion and the data analysis permitted developing a characterization of the early childhood education in the city studied, evidencing the constitution of a business network propelled by the acquisition of vacancies in the private sector and by the judicialization of this educational stage. Thus, the right to education – understood as the access to quality education for all in State institutions that provide care and education to children without considering them as a business – may be in danger, indicating a trend to privatization. It is concluded that the public character of education is decreasing as city policies are aligned to privatizing processes in a market rationale that transforms the citizen into a client. We emphasize that the right to education must be based on laicity, gratuity and quality, accessible for all as constitutionally foreseen. Not only the access must be guaranteed, but the equal access for all.

SPONTANEOUS ORDERING OF CHEMOCONVECTIVE FINGERING NEAR AN INTERFACE IN A REACTING SOLUTION
Authors: Utochkin Vladimir Yu. , Bratsun Dmitry A.
Published: November 2022

In this work, we develop a mathematical model of buoyancy-driven mass transfer in an aqueous alkali solution filling a Hele-Shaw cell. The upper boundary of the layer is free and nondeformable. The acid flux through the interface is determined by the constant value of the acid concentration set at the interface. Thus, the neutralization reaction proceeds near the interface and is accompanied by the formation of salt and water. We neglect the heat release of the exothermic reaction and the Marangoni effect, assuming that all substances do not exhibit surface activity. The ratio of the initial concentrations of acid and base is the control parameter of the system, which unambiguously determines the onset of various types of chemoconvection. The described model reproduces the main properties of a two-layer system of immiscible reacting liquids if the interface is impermeable to base and salt. Based on recent experimental observations, we modify the equation of solvent motion, introducing an integral term that describes the reaction-induced production of water. We demonstrate that such an assumption drastically changes the density distribution in the system because of the depletion of solutions in the reaction zone. In particular, this effect leads to spontaneous stabilization of fingering process in the parameter range, where numerical simulation of the standard model predicts the development of disordered Rayleigh-Taylor convection. Finally, we present a bifurcation diagram for the ratio of initial concentrations. The obtained results are in good agreement with the experimental data.
A graphical method for undrained analysis of cavity expansion in Mohr–Coulomb soil
Authors: Chen Sheng-Li , Wang Xu
Published: November 2022

A rigorous analytical solution is developed for undrained cavity expansion problems in non-associated Mohr–Coulomb soil, based on a novel graphical analysis approach and on the Lagrangian description through tracking only the responses of a soil particle at the cavity surface. The mathematical difficulties involved with the flow rate calculation when the stress state lies on the corner/edge of two adjacent (Mohr–Coulomb) yield surfaces, for both cylindrical and spherical cases, are tackled by using the generalised Koiter theory for non-associated plasticity. In particular, through the unique geometrical formulation, the effective stress path pertaining to the cylindrical cavity problem can be very conveniently directly determined, and is found to consist of simple, piecewise straight lines in the deviatoric stress plane with the orientations dependent of the relative magnitude of Poisson's ratio and the friction angle. This thus renders possible the removal of the stringent intermediacy assumption for the vertical stress that is commonly adopted in previous formulations, and hence the development of a complete cylindrical cavity expansion solution in Mohr–Coulomb soil under undrained loading conditions. The stress and deformation responses of the cavity, including the typical pressure–expansion curves and limiting cavity pressure, are finally analytically obtained along with the Lagrangian form of the radial equilibrium equation in completely explicit forms. The closed-form solution provided in this paper is the first rigorous one of its kind, thus completing the analytical analysis of the cavity expansion problem with the classical Mohr–Coulomb model; this is deemed to be essential for the interpretation of in situ test results pertaining to cohesive-frictional soils.

DESCARTES'TA 'DÜŞÜNÜYORUM' VE RUHUN VARLIĞININ ARGÜMANLARI
Authors: ÖZGÖKMAN Fatih
Published: November 2022

ÖZ

Descartes, Meditasyonlar’da insan ruhunun veya zihninin bedenden ayrı olarak var olduğuna dair üç argüman sunar. Birincisinde “düşünüyorum o halde varım” ile var olmanın en temel biçiminin düşünmek yani kendisine dair bilinci olduğunu fark eder ve bunun şüphe götürmez kesinliğinden hareketle kendisinin diğer duyulur şeyler gibi şüphe götüren bedenden farklı olduğu sonucunu çıkarır. İkincisinde ise Descartes zihin ve bedenin kavramsal olarak birbirlerinden ayrı düşünülebilmesi nedeniyle gerçeklikte de ayrı olduklarını savunur. Çünkü düşüncemizin gerçekliğe uymaması için bir gerekçe yoktur. Üçüncüsünde ise Descartes, Platoncu ruhun basitliği argümanına baş vurur. Buna göre ruh tüm zihinsel faaliyetlerinde bölünemez iken beden uzamlı olduğu için bölünebilir ve bu nedenle de eksilebilir. Halbuki bedenin eksilmesiyle ruhta hiçbir eksilme ortaya çıkmaz. Bu durum ruhun veya zihnin bedenden ayrı olduğunu ortaya koyar.

Heat-constrained modelling of calcium sulphate reduction
Authors: Jordan L.A. , van Vuuren D.
Published: November 2022

A two-dimensional finite difference model has been developed to describe the reduction of kilogram quantities of dehydrated phosphogypsum. The model's scope has been limited to focus on the heat transfer and reactions that occur within a mass of material contained in a vessel inside a furnace rather than also including the effects of heat transfer to the vessel. Changes in the heat transfer properties (k, p, and Cp) are incorporated as the composition of the mass changes as the chemical reactions progress. The model is validated against experimental data, with samples heated to iooo°C at 3°C min-1 while purging with nitrogen gas. A sensitivity analysis of model predictions to the pre-exponential factor of the reaction rate constant of the main chemical reaction and the thermal conductivity of the powder bed indicated that, at the envisaged process conditions, the behaviour of the system depends much more on the rate of heat transfer than on the rate of the chemical reaction. The model demonstrated a significant increase in accuracy when the thermal conductivity was modelled to increase linearly with temperature compared to assuming a constant value.
Evaluation of pre-treatment methods for gold recovery from refractory calcine tailings
Authors: Mutimutema P. , Akdogan G. , Tadie M.
Published: November 2022

The South African gold mining industry has a legacy of abundant tailings dams, which have attracted the attention of investors because of their potential as a cheaper secondary gold resource. In this we investigate study gold recovery from a refractory calcine tailings dam. Bulk mineralogy of the tailings indicated silicates and iron oxides to be the most abundant phases. Scanning Electron Microscopy (SEM) showed gold to exist in submicrometre and micrometre sizes, as free gold, and associated with arsenic, sulphur, and silicates e.g. quartz and talc. Gold recovery by direct cyanidation was low at 17.3%. Mechanical (ultra fine grinding P80 -16µm) and chemical (alkaline, NaOH) pre-treatment and microwave roasting and microwave-assisted cyanide leaching were investigated to increase gold recoveries. Ultrafine grinding was the most effective, producing recoveries of 66.5%. NaOH pre-leaching of ultrafine milled material increased recovery to 71.5%. Alkaline pre-leaching overall increased recoveries for non-pre-treated material, making this process the most preferred because it is less costly than ultrafine grinding. Microwave roasting and microwave-assisted leaching did not achieve higher recoveries than alkaline pre-treatment or fine grinding. The investigation highlights and confirms that chemical treatment with NaOH is a powerful tool for gold extraction from refractory tailings.

“Double Ageing” in the High-Rise Residential Buildings of Tokyo
Authors: Hirai Taro
Published: November 2022

This study aims to explore the current “double ageing” (demographic ageing of residents and physical ageing of facilities) in high-rise (over 20 stories by the Japanese Government’s definition) residential buildings in Tokyo, where the rate of ageing has increased most rapidly since the late 1990s, compared to those of other cities and high-rise residential buildings worldwide. First, the trend of demographic ageing in the districts where high-rise residential buildings are concentrated is analysed. The results show that demographic ageing in high-rise residential buildings is faster than in other residential buildings because the age group of the residents is concentrated across two generations: the generation born in 1946–1955 and the generation born in 1966–75. Second, the relationship between demographic and physical ageing was examined through an online survey of 978 residents of high-rise residential buildings conducted in January 2021. A generation gap in values regarding their high-rise residential buildings was clearly identified. Third, the cause and result of the generation concentration and gap were investigated via an interview survey of 26 informants extracted from the online survey. Three main findings emerged: (a) the ageing of the generation born in 1946–1955 has given rise to housing insecurity because of the decline in income, (b) the high rate of singles within the generation born in 1966–1975 may be as a result of housing insecurity after their retirement, and (c) the introduction of social distancing has accelerated the substantial “ageing” of relatively good facilities, but a straightforward generational conflict was not fully deciphered in this article because of lifestyle diversification over generations and organisational culture of management associations.
Cross-Layer Routing Based on Semantic Web Services Discovery with Energy Evaluation and Optimization in MANET

Published: November 2022

The web services discovery process in mobile adhoc networks is considered as a very difficult challenge due to the continuous change in the topology of the network and also the lack of a fixed central directory for publishing web services. Several approaches have been proposed which are based on either keywords or identifiers representing the service to be searched or by using a specific scenario of discovery. All of those proposed solutions try to respect the constraints of ad hoc networks such as energy, bandwidth, throughput ... etc. In this paper we present our new proposed model for measuring the cost of the overall energy consumption in ad hoc networks depending on the web services discovery protocols. We also present a new optimized web services discovery protocol in MANET based on cross_layer routing techniques with the dissemination in the routing process at the same time the semantic web services information and a Discovery_Diameter parameter that we have proposed to limit the area of discovery in the network. Finally, we present simulation results of our defined approach showing a significant optimization of the energy consumption level and the average throughput.
Optimal Cluster Head in DTN Routing Hierarchical Topology (DRHT)

Published: November 2022

In delay tolerant networking (DTN), nodes are autonomous and behave in an unpredictable way. Consequently, a control mechanism of topology is necessary. This mechanism should ensure the overall connectivity of the network taking into account nodes’ mobility. In this paper, we study the problem of data routing with an optimal delay in the bundle layer, by exploiting: the clustering, the messages ferries and the optimal election of cluster head (CH). We first introduce the DTN routing hierarchical topology (DRHT) which incorporates these three factors into the routing metric. We propose an optimal approach to elect a CH based on four criteria: the residual energy, the intra-cluster distance, the node degree and the head count of probable CHs. We proceed then to model a Markov decision process (MDP) to decide the optimal moment for sending data in order to ensure a higher delivery rate within a reasonable delay. At the end, we present the simulation results demonstrating the effectiveness of the DRHT. Our simulation shows that while using the DRHT which is based on the optimal election of CH, the traffic control during the TTL interval (Time To Live) is balanced, which greatly increases the delivery rate of bundles and decreases the loss rate.

Published: November 2022

The evolvement of wireless technologies has enabled revolutionizing the health-care industry by monitor patient health condition requiring early diagnosis and interfering when a chronic situation is taking place. In this regard, miniaturized biosensors have been manufactured to cover various medical applications forming therefore a Wireless Body Sensor Network (WBSN). A WBSN is comprised of several small and low power devices capable of sensing vital signs such as heart rate, blood glucose, body temperature etc.. Although WBSN main purpose is to provide the most convenient wireless setting for the networking of human body sensors, there are still a great number of technical challenges to resolve such as: power source miniaturization, low power transceivers, biocompatibility, secure data transfer, minimum transmission delay and high quality of service. These challenges have to be taken into consideration when creating a new routing protocol for WBSNs. This paper proposes a new Relay based Thermal aware and Mobile Routing Protocol (RTM-RP) for Wireless Body Sensor Networks tackling the problem of high energy consumption and high temperature increase where the mobility is a crucial constraint to handle.

Today the field of wireless sensors have the dominance in almost every person’s daily life. Therefore researchers are exasperating to make these sensors more dynamic, accurate and high performance computational devices as well as small in size, and also in the application area of these small sensors. The wearable sensors are the one type which are used to acquire a person’s behavioral characteristics. The applications of wearable sensors are healthcare, entertainment, fitness, security and military etc. Human activity recognition (HAR) is the one example, where data received from wearable sensors are further processed to identify the activities executed by the individuals. The HAR system can be used in fall detection, fall prevention and also in posture recognition. The recognition of activities is further divided into two categories, the un-supervised learning and the supervised learning. In this paper we first discussed some existing wearable sensors based HAR systems, then briefly described some classifiers (supervised learning) and then the methodology of how we applied the multiple classification techniques using a benchmark data set of the shimmer sensors placed on human body, to recognize the human activity. Our results shows that the methods are exceptionally accurate and efficient in comparison with other classification methods. We also compare the results and analyzed the accuracy of different classifiers.
MMEDD: Multithreading Model for an Efficient Data Delivery in wireless sensor networks

Published: November 2022

Nowadays, the use of Wireless Sensor Networks (WSNs) is increasingly growing as they allow a large number of applications. In a large scale sensor network, communication among sensors is achieved by using a multihop communication. However, since the sensor is limited by its resources, sensors' operating systems are developed in order to optimize the management of these resources, especially the power consumption. Therefore, the hybrid operating system Contiki uses a low consumption layer called Rime which allows sensors to perform multihop sending with a low energy cost. This is favored by the implementation of lightweight processes called protothreads. These processes have a good efficiency/consumption ratio for monolithic tasks, but the management of several tasks remains a problem. In order to enable multitasking, Contiki provides to users a preemptive multithreading module that allows the management of multiple threads. However, it usually causes greater energy wastage. To improve multithreading in sensor networks, a Multithreading Model for an Efficient Data Delivery (MMEDD) using protothreads is proposed in this paper. Intensive experiments have been conducted on COOJA simulator that is integrated in Contiki. The results show that  MMEDD provides better ratio message reception rate/energy consumption than other architectures.

Published: November 2022

BACKGROUND. Cognitive impairment is common after a stroke. However, the condition of social cognitive functions, in particular theory of mind, in this group of patients has been studied insufficiently.
AIM. To study the frequency and predictors of the development of the social cognitive disorders based on theory of mind impairment in patients with acute ischemic stroke.
MATERIAL AND METHODS. Theory of mind impairment was assessed using Reading the Mind in the Eyes test in the acute period of ischemic stroke. National Institutes of Health Stroke scale was used to assess the severity of neurological deficit, modified Rankin scale the degree of disability, Delirium Severity Rating Scale the symptoms of delirium, Buss Perry aggressiveness scale severity of aggressive behavior, Montreal Cognitive Assessment Scale cognitive deficit. The severity of cortical atrophy was evaluated by computed tomography of the brain. The study included 86 patients, 53 males and 33 females. The average age of patients was 64 years. Statistical analysis was performed using the IBM SPSS Statistics 21 software package. Nonparametric statistics methods were used. Binary data were compared using the chi-square parameter, categorical data were compared using the MannWhitney test.
RESULTS. Seventy percent of patients suffered from the impairment of social cognitive functions. Independent predictors of the impairment of theory of mind according to linear regression analysis were cognitive dysfunction according to the Montreal Cognitive Assessment Scale (p=0.0001) and the severity of cortical atrophy on computed tomography of the brain (p=0.001).
CONCLUSION. Social cognitive impairment is registered in a substantial number of patients in acute period of stroke; its predictors include general cognitive impairment and cortical atrophy of the brain.

MATERIAL AND METHODS. 61 outpatient patients with paranoid schizophrenia (28 men and 33 women) were examined at the stage of remission of the disease. Clinical and scale assessment was carried out using the PANSS, PSP, CGI-S, DAI scales.
RESULTS. There were more married women than men. Restriction of professional activity and social contacts was more often observed in male patients. Among patients without disabilities and patients with the 3rd disability group, female persons prevailed, while among patients with the 2nd disability group men. It was shown that the age of onset of the disease was significantly less in men than in women. The indicator of the severity of the disease on the CGI-S scale during remission corresponded to moderate severity in men and mild severity in women (p 0.05). The severity of residual productive and, especially, negative symptoms is greater in male patients. The level of social and everyday functioning according to PSP is higher for women than for men. Noticeable disorders prevailed in patients of both sexes, however, they were observed more often among men, while women more often than male patients had minor difficulties in certain areas of functioning. The most pronounced differences were found in the degree of impaired functioning in the behavioral sphere. The paranoid type of remission unfavorable with respect to social functioning was more often observed in men. For women, the thymopathic type of remission turned out to be the most favorable from the point of view of compliance and social functioning. Antipsychotics of the first generation were more often prescribed for the paranoid type of remission in both men and women, while therapy with antipsychotics of the second generation was associated with the most favorable remission options for both men (apathetic type) and women (thymopathic type), which correlated with a higher level of social functioning. In general, the level of social functioning was higher when prescribing second-generation antipsychotics, regardless of the gender of patients with schizophrenia.
CONCLUSION. The hypothesis about the best outcome of the disease in the framework of personal and social recovery in women has been confirmed.

The Annexation of Crimea and EU Sanctions: An Ineffective Response
Authors: Barron Kiegan
Published: November 2022

Ongoing geopolitical developments regarding Russia and Ukraine have resulted in discussions about the utility of sanctions. This article analyzes European Union (EU) sanctions on Russia following the annexation of Crimea by investigating whether EU-Russia oil and gas trade relations compromised the efficacy of restrictions. It thus argues that the EU did not sanction Russian oil and gas due to EU reliance on these resources. However, the absence of sanctions on these industries cannot be held responsible for Russia’s refusal to leave Crimea since restrictions that were put in place still notably impacted the Russian economy. Hence, other considerations, such as the general inefficacy of sanctions, unintended consequences of the EU restrictions, and deeper historical reasoning clarify why Russia’s occupation of Crimea persisted.
A THEORETICAL MODEL FOR DESCRIPTION OF WORK FUNCTION LOWERING FOR SEMICONDUCTOR / INSULATOR UNDER THE INFLUENCE OF THE CHARGED BILAYER IN THE SURFACE REGION
Authors: Strikha M. V. , Goriachko A. M.
Published: November 2022

We develop a simple theoretical model, connecting a  lowering of the electron affinity of a semiconductor  (or insulator) with such parameters as the density of  surface charge, localized on surface states or  adsorbed atoms, and the volume density of charge  within the space charge region, both of which form a charged bilayer on the surface. Our model allows to estimate the perspectiveness of various materials as films for creating modern photocathodes or effective field emission cathodes with substantially lowered or zero work function.

O Brasil é o maior produtor de café do mundo e o segundo maior consumidor dessa bebida, fato que retrata a grande importância econômica dessa cultura para o país. Como todo processo agroindustrial, o beneficiamento do fruto do café gera uma grande quantidade de resíduos. Um desses subprodutos é obtido na etapa de torrefação, denominado endocarpo ou película prateada, utilizado até o presente momento na fabricação de ração animal e como substrato para cultivo de plantas. O objetivo deste estudo foi utilizar a película prateada como matéria-prima para a produção de um alimento: flocos crocantes. A película prateada foi fornecida por uma empresa processadora de café do município de Chapecó/SC. Inicialmente, produziu-se uma farinha com a película prateada, que em seguida foi utilizada na elaboração de flocos crocantes. Foram realizadas análises microbiológicas do produto final e os resultados, quando comparados com a legislação de um grupo similar, estavam de acordo com os padrões legais exigidos. O mesmo aconteceu com as análises físico-químicas. Também foi realizada a análise sensorial dos flocos crocantes, utilizando escala hedônica, bem como intensão de compra. O teste de aceitabilidade revelou o potencial de aceitação do produto testado, com um índice de aceitabilidade de 85,17% em todos os aspectos analisados.
Teoria dos sistemas e retórica analítica: possíveis convergências em torno da crítica à cientificidade da dogmática jurídica
Authors: Parini Marques de Lima Pedro , Luna Machado de Azevedo Isaac , Lins Tiburtino dos Santos Raphael Henrique
Published: November 2022

O presente artigo se propõe a examinar possíveis pontos de convergência entre a retórica analítica de Ottmar Ballweg e a teoria dos sistemas de Luhmann no tocante à impossibilidade de concepção de uma dogmática jurídica verdadeiramente analítica, ou seja, de um conhecimento científico do direito dentro dos limites do próprio direito. Procura-se demonstrar que ambas as correntes concordam quanto ao fato de que um saber científico sobre o direito estaria necessariamente localizado em uma dimensão analítica duplamente reflexiva, convergindo, ainda, quanto à inexistência de uma ciência “do” direito, admitindo, ao revés, apenas a possibilidade de uma ciência “sobre” o direito.
Determination of Linear Udder Traits of Norduz Sheep
Authors: Karakus Ferda
Published: November 2022

Background: A limited number of studies in non-dairy sheep breeds have investigated the assessment of udder morphology on a linear scale. The aim of this study was to use the linear scoring approach to determine the morphological udder traits of non-dairy Norduz ewes. Methods: Udder traits were measured once in mid-lactation (approximately 90 days) for each ewe before the milking. Udder measurements included the following traits: udder width, udder circumference, udder length, udder depth, teat diameter, teat length, the distance between two teats and teat height from the ground. Linear scoring was done after the udder measurements were taken. Result: Linear udder scores for teat placement, udder depth, the degree of separation of two halves and the degree of udder suspension were found as 4.10, 6.88, 3.15 and 7.54, respectively. Measurements related to udder size were positively and significantly correlated with each other. As a result, the 9-point linear scale utilized in this study was found to be appropriate for evaluating the udder shape of Norduz ewes. However, it would be beneficial to develop an uncomplicated, easy and practical linear scale that accurately evaluates udder morphology for non-dairy breeds.
