Authors:   Branch of Institute of Natural and Technical Systems in Sochi, Rudnev V.P.
Published: December 2021

The use of transparent thermoplastics as construction materials imposes special requirements on them, both in terms of strength characteristics and physical properties. The stability of these properties plays an important role in the use of transparent thermoplastics in complex technical systems, where these materials are used as a structural material for the outer contour of the product, which is exposed to aggressive climatic factors. In this work, the influence of atmospheric factors in the warm humid climate zone (the coastal atmosphere of humid subtropics) on the optical properties of transparent thermoplastics was investigated, which made it possible to obtain important information for assessing the performance of polymers of this class in natural climatic conditions.

In the paper statistical distribution of the highest wind speed per year in the Azov and Black Sea region was analyzed using the data of 33 meteorological stations for 1958-2013. A statistical estimation of the wind speed extremes was carried out by approximation of the empirical sample with a function of Generalized distribution of Extreme Values (GEV) and by extrapolating it to the low probabilities region. We used two methodologies and applied statistical distribution functions corresponding to them. The first method is based on the assumption of stationarity of parameters of the GEV function. The second one is based on the non-stationary assumption of time dependence of extremum localization parameter μ. It was found, that for 13 out of 33 stations of the region, non-stationary GEV-function turned out to be adequate to describe extreme wind speeds.

The regularities of the suspended matter distribution in the system of wind currents from the area of bottom elevation along the Omega Bay are revealed. Observational data show that in the region of bottom elevation there is a topographic quasi-stationary eddy cell accumulating pollutants. Based on numerical modeling, it is revealed that the meridional winds of all directions contribute to the transfer of the suspended matter from the area of elevation to the western coast of the bay to the beach area, to a small coastal area with a characteristic bend of the coastline. The most significant suspended matter flows are generated by northeasterly and southeasterly winds. With a westerly wind, the main flow of suspended matter is directed to the eastern coast of the bay. The weak easterly winds, typical for Sevastopol, do not cause the removal of suspended matter from the central area of the investigated bay.

In an adolescent, the development phase causes a variety of conflicts. One of the most common problems among adolescents is the issue of love breakup. It can lead to the disruption of self-concept which eventually leads to a failure to overcome real problems. Hence, this study was conducted to explore the effectiveness of Rational Emotive Behavioral Therapy (REBT) to address the problem of self -concept among adolescents. This is a qualitative study using interview sessions as a study design. The study was based on a counseling case of a teenage female client who was going through a breakup. The client suffered from depression and feels inferior to her self -image and chooses to isolate herself from others. Thus, the Rational Emotive Behavioral Therapy (REBT) was utilized to reestablish the client's self -concept. REBT therapy enables the client to change the negative way of thinking to positive and rationalize her thinking to avoid her feeling depressed with the issue of the breakup. This is important in ensuring that the client successfully solves her problems and can give full commitment to her learning and responsibilities.
Lessons for Liberalism: Lord Brougham's Philosophy of Italian Politics
Authors: Pearce Colin
Published: December 2021

In this paper I attempt to give an historically accurate statement of the fundamentals of Henry Peter Brougham, First Baron Brougham and Vaux's (1778-1867) political philosophy and to show how he seeks guidance in his development of this philosophy from the materials of history in general and Italian history in particular. The article seeks to explain Brougham's view that history should be written in a "non-historicist," "objective," "absolutist" and "judgmental" manner and that this position is linked to his belief that there are rationally demonstrable supreme objects of legitimate government which can be shown to be obligatory on all governments at all times however much the prevailing historical conditions may limit or condition actual practical choices. Brougham will be shown to be a proponent of representative, popular government over an extended territory as the best means to attaining the legitimate objects of government in the form of domestic order and external security. Brougham comes to this conclusion while being aware of the great advantages to be had from the absolute rule of one wise and virtuous monarch and the necessity for a purely democratic constitution when the conditions of public enlightenment and social advancement have reached their apogee. In outlining this portrait the article indicates some of the connecting links between Brougham's thought and that of both ancient and modern political philosophers as it was known to him. We find in Brougham a certain blend or melding of various strands within the tradition of liberal thought which as a central figure in the politics of the British Empire during the first third of the nineteenth century he was able to advance on the practical level. It is the hope of this article to contribute in some small way to the re-discovery of a heretofore undeservedly neglected or at least underestimated historical figure.

The number and heterogeneity of mast cells in broiler ileum at different post-hatching periods
Authors: ERTUĞRUL Tuğrul
Published: December 2021

Mast cells are found close to surfaces that interface with the external environment, particularly the skin, respiratory, and digestive systems. The number of mast cells at a given site can vary depending on the host's location and immunologic status. This study was undertaken to determine the number of mast cells and their heterogeneity in broilers' ileum during the post-hatching period. The number and heterogeneity of mast cells were studied in the ileum tissue of 0-, 7-, 21- and 42-day old broilers. Mast cells were stained metacromasically with toluidine blue in all groups. Mast cells were observed in all the ileum layers, mainly in the lamina propria of the mucosa and submucosa. They were also observed in connective tissue around capillaries and between smooth muscle cells in the tunica muscularis layer. Both blue-colored AB (+) and red-pink-colored SO (+) mast cell subtypes were seen in the ileum. AB (+) mast cells were observed in all age groups, whereas no SO (+) mast cells were found in the 0- age group. SO (+) mast cells were first detected in the ileum tissue on the seventh day after post-hatching. As a result, the number of mast cells was found to increase with age, which was statistically significant.
CHALLENGES FACED IN IMPLEMENTING FREE PRIMARY EDUCATION FOR PASTORALISTS IN KENYA
Authors: Serem David , Ronoh Richard Kipngeno
Published: December 2021

Governments in Sub-Saharan Africa allocate between 5% and 25% of public expenditure budgets to education ministries, because education is seen, correctly, as a major contributor to human welfare, social and economic development (World Bank, 2005). It is clear that these large expenditures are sub-optimal and provide less than the expected return. This situation has been felt more acutely with the introduction of free primary education (FPE). Despite the high enrolment in FPE in urban areas, the response from pastoral communities has been rather lukewarm.The general objective of the study was to investigate the challenges faced in implementing Free Primary Education policy among pastoralists in Kenya. Consequently, the rationale of this study lies in need to evaluate the impact of an educational policy and find out how its implementation responds to challenges in provision of access to Primary Schooling. The study adopted ethnographic research design that utilised purposive sampling technique and saturation procedure to select a total of 170 respondents that included head teachers, teachers, parents, school dropouts, educational managers, community leaders, and Non Governmental Organizations. Purposive sampling was used to select individuals, groups and organizations that would provide insight into the study. Data was collected using focus group interviews, structured and unstructured interviews, observation, and document analysis. Subsequently, data was collected by use of questionnaire that was sent to head-teachers and education officials and was used only to validate the qualitative data. The collected data was coded, analyzed, described and summarized in order to generate themes on educational policy and practice. The study identified various challenges such as: inadequate funding; poor infrastructure; limited awareness towards education; limited community support; insecurity and cattle rustling and lifestyle of pastoralists that impedes the government’s efforts to attain FPE. These challenges threatened the implementation of FPE for pastoralists and further illustrate the complex and messy process of policy implementation in education sector.
Key words: free primary education (FPE), policy implementation, pastoral communities, challenges.
TEXTILE CRAFT STUDENTS’ PERCEPTIONS OF SUSTAINABLE CRAFTS
Authors: Vartiainen Leena , Kaipainen Minna
Published: December 2021

Future teachers have an important role in education for sustainable development. This article describes textile craft teacher students’ perceptions of sustainable textile craft. The data derives from a survey of craft teacher students of the University of Eastern Finland (N = 20). The questionnaire included open-ended and multiple choice questions about sustainability of textile craft education and the relevance of sustainability in the students’ lives. The study reveals textile craft teacher students’ conceptions as consumers, craft makers and future textile craft teachers. The open-ended questions were analyzed by content analysis and the multiple choice questions were analyzed with statistical methods. The results were reflected to Victor Papanek’s function complex.
As consumers, students favour good quality products and recycling of textiles. They are concerned about workers’ work conditions and against child labour. Although values and perceptions related to sustainable consumerism are high, sometimes the actual purchasing behaviour differs from the values because of the students’ meagre budgets. As craft makers, availability of locally produced materials and materials made of natural fibres are important to students. As future textile craft teachers, students think that craft is an excellent way to teach sustainability and sustainable craft. They consider it is important to teach life-cycle thinking but also craft culture and skills.
Key words: clothing and textile design, sustainable craft, textile craft teachers.

Authors: Morales Rodríguez Francisco Manuel
Published: December 2021

The transformation process occurring in the educational field, which has resulted from the generalized development and application of the Information and Communication Technologies (ICT), differs from preceding technological revolutions in the amazingly accelerated pace it sets. Reflecting upon the implications of the generalized and increasing adoption of ICT is undeniably important for the present and future of social sciences and, particularly, for the areas of pedagogy and didactics. The new model of Higher Education involves new methods, demands and challenges, where the use of ICT represents one of the basic competences. The present study aims to provide an evaluation of interests and attitudes towards Information and Communication Technologies (ICT) in a sample of 224 post-graduate students of the Master's Degree in Teacher Training: Secondary and Upper Secondary Education, Vocational Training and Language Teaching, aged from 22 to 49 years old. The questionnaire includes questions aimed to evaluate different aspects, which facilitate interactive learning: computer knowledge; knowing the value of the Internet; place and frequency of online access; and usefulness of certain tools such as video-film, power point, Moodle, forums, wikis, chats, video-forums and blogs. Additionally, the questionnaire includes a number of questions about the potential applications of the Internet in an educational context. Results showed that all students are familiar with the Internet and that they first got to know it from friends. More important is the fact that most of them consider the Internet as a potential educational resource and not only as a support or reinforcement tool that complements the textbook and they like to use ICT and think of them as useful tools in their learning/teaching process. There are differences based on gender and specialization in the perception of the role that ICT is to play in the university context. In particular, men from the specialization Foreign Language consider that weblogs do facilitate peer-to-peer and student-teacher communication and give less importance than women to the item stating that the families’ socioeconomic level has an influence on our knowledge of the Internet. To conclude, the information obtained from the present study is of interest both for training teachers and for integrating ICT in the academic curricula.

Concluded, it can be concluded that there is a meaningful relationship between the level of knowledge and anxiety levels of breastfeeding mothers in the Covid-19 pandemic.
The IMF or the AMF: Defining the Future of Financing for Investment and Development Projects in Africa
Authors: Masumbe PS
Published: December 2021

Since independence the government of many African countries have depended on the International Monetary Fund (IMF) and the World Bank as their main sources of finance for major developmental and investment projects in their respective countries. Accordingly, besides the granting of loans to Low Income Countries (LICs) at zero interest rate, the IMF also assists member countries to resolve their balance of payment challenges as well as granting interest-bearing loans to both member and non-member countries. Similarly, the African Monetary Fund (AMF) which is a prototype of the IMF was created by the African Union (AU) and is not yet operational. Just like the IMF, the AMF is intended to fund major developmental projects in Africa. This article examines the IMF loans conditionality and the award of Special Drawing Rights (SDR) to African Countries as seen during the COVID-19 crisis. It argues that the AMF would not be the African countries’ panacea as far as funding for developmental projects in Africa is concerned. In this regard, the article further examines Agenda 2063 as a future development model for Africa, as well as the various sources of project finance as envisioned in the Frameworks Document of Agenda 2063. It concludes that IMF still has the financial muscle to fund developmental projects and resolved balance of payment problems in Africa despite alternative sources of finance recommended by Agenda 2063.

Published: December 2021

Objective : To evaluate the interactions among differentially expressed autophagy and mitophagy markers in subarachnoid hemorrhage (SAH) patients with delayed cerebral ischemia (DCI).Methods : The expression data of autophagy and mitophagy-related makers in the cerebrospinal fluid (CSF) cells was analyzed by real-time reverse transcription-polymerase chain reaction and Western blotting. The markers included death-associated protein kinase (DAPK)-1, BCL2 interacting protein 3 like (BNIP3L), Bcl-1 antagonist X, phosphatase and tensin homolog-induced kinase (PINK), Unc-51 like autophagy activating kinase 1, nuclear dot protein 52, and p62. In silico functional analyses including gene ontology enrichment and the protein-protein interaction network were performed.Results : A total of 56 SAH patients were included and 22 (38.6%) of them experienced DCI. The DCI patients had significantly increased mRNA levels of DAPK1, BNIP3L, and PINK1, and increased expression of BECN1 compared to the non-DCI patients. The most enriched biological process was the positive regulation of autophagy, followed by the response to mitochondrial depolarization. The molecular functions ubiquitin-like protein ligase binding and ubiquitin-protein ligase binding were enriched. In the cluster of cellular components, Lewy bodies and the phagophore assembly site were enriched. BECN1 was the most connected gene among the differentially expressed markers related to autophagy and mitophagy in the development of DCI.Conclusion : Our study may provide novel insight into mitochondrial dysfunction in DCI pathogenesis.

Camu-camu is an exotic fruit, known for having high concentrations of vitamin C and bioactive compounds. In order to diversify the consumption of this fruit, this study developed milk ice cream formulations and evaluated the effect of the addition of different concentrations of camu-camu pulp (20 to 26%), sugar (12 to 14%) and defatted dry extract (DDE) (12 to 16%) through a mixture design. Ice creams were evaluated by analyses of overrun, density, melting time, ratio, and cost. Three formulations were defined based on maximum melting time and ratio and minimum cost. The ice creams formulations defined by the experimental design consisted of the following proportions of pulp, sugar and DDE (%): 26:12:12, 20:14:16 and 24:14:12. These formulations were evaluated in relation to their physicochemical and technological characteristics, antioxidant and reducing capacity and sensory acceptance. The results showed that all formulations had high concentrations of antioxidant compounds and vitamin C and the formulation with the addition of camu-camu pulp lower than 24% had greater sensory acceptance. Therefore, it is concluded that the addition of camu-camu pulp in milk ice cream is interesting from a nutritional point of view, as it can increase the content of nutrients and minerals in the final blend.

A COVID-19 consiste na doença causada pela infecção do vírus SARS-CoV-2. A população pediátrica, corresponde de 1 a 5% dos casos confirmados da doença, variando de acordo com o país em estudo. Este trabalho tem como objetivo analisar os casos infantojuvenis suspeitos e confirmados de COVID-19 em um hospital de Sergipe. Trata-se de um estudo observacional transversal envolvendo 1.388 pacientes, menores de 20 anos, durante março de 2020 e setembro de 2021. Entre os pacientes, 54,8% eram do sexo masculino, 10,4% apresentavam alguma comorbidades. Observou-se que a dispneia estava relacionada com a faixa etária, sendo frequente em crianças. Além disso, algumas manifestações clínicas foram associadas a infecção pelo SARS-CoV-2, como cefaleia (p= 0,021), diarreia (p= 0,002), desconforto respiratório (p<0,001), dispneia (p<0,001), espirro (p<0,001) e saturação de O2 < 95% (p<0,001). Houve relação entre os pacientes que evoluíram para óbito com algumas variáveis como presença de comorbidades, desconforto respiratório, espirro, necessidade de estabilização e UTI (p< 0,001). A maioria dos casos pediátricos são assintomáticos ou leves, além disso as crianças apresentam melhor desfecho na COVID-19, visto que um pequeno percentual evolui para óbito, geralmente associado com a presença de comorbidades pré-hospitalares.

Introdução: A Aids é uma doença que se caracteriza pela deficiência do sistema imunológico e que, no passado, trouxe para os seus portadores grande estigma social e baixa expectativa de vida. Com o aumento da expectativa de vida, surgiram novas questões de saúde dentre essa população relacionadas tanto ao envelhecimento quanto ao quadro de vulnerabilidade do HIV, o que resultou na complexidade inerente ao manejo farmacológico de doenças concomitante à terapia antirretroviral e seus riscos iatrogênicos inadvertidos, destacando-se assim a interação entre o Ritonavir. Método: Foi realizada uma revisão de literatura nas bases de dados on-line da Biblioteca Virtual em Saúde (BVS), com a utilização dos descritores: “Iatrogenic Cushing´s syndrome” AND “HIV” de 2011 a 2021. Resultados e discussão: 24 artigos foram encontrados, 2 eram revisões de literatura com abordagem sobre a relação entre o HIV e a síndrome de Cushing iatrogênica e 22 correspondiam a relatos de caso que tinham por base pacientes portadores de HIV em associação a doenças crônicas desenvolvidas pela idade, com destaque para as afecções osteomusculares, respiratórias e reumatológicas. Em função dessa combinação, a polifarmácia era aplicada, sendo o uso de corticoides e a terapia antirretroviral com o Ritonavir o fator farmacológico convergente entre todos os casos, bem como a principal manifestação clínica: A Síndrome de Cushing. Conclusão: Notou-se que o uso de glicocorticóides exógenos, como Triancinolona, Fluticasona e a Budesonida, que interagem com o Ritonavir, em pacientes que fazem uso de terapia antirretroviral do HIV pode induzir quadros clínicos da síndrome de Cushing.

Introduction / Objective: Based on the assumption that pain can be perceived as punishment (pain = penalty), and that this concept of guilt is present in the Judeo-Christian civilization, we decided to review the literature on relevant religious and guilt - which is also a source of suffering - in the management of chronic pain. Methodology. Three searches were carried out that included all articles listed until July 2021 within the PUBMED database. MeshTerm and Boolean operators were used in the following combinations: chronic pain AND religion AND guilt NOT yoga NOT meditation; Chronic pain AND religion NOT yoga NOT meditation; chronic pain AND guilt. Results. Studies carried out in different countries point to the relevance of the chronic relationship of chronic pain to the patient, interfering in a positive way in their evolution, without, however, investigating their relationship with feelings of guilt. Conclusions. The literature is rich in articles on the influence of religiosity in coping with pain, but mentions of feelings of guilt are limited to a single article.

A criação do Sistema Único de Saúde (SUS) assegurou a participação popular – sendo uma das formas os Conselhos de Saúde (CS) - nos processos de execução e fiscalização de políticas voltadas para a promoção da saúde em todo o país. Objetivou-se com esta pesquisa, avaliar como os CS atuam como estratégias de participação no desenvolvimento do SUS. Trata-se de uma revisão integrativa, com dados obtidos a partir da busca bibliográfica por meio dos descritores: participação popular, sistema único de saúde e conselho de saúde; foram encontrados 66 artigos. Após serem aplicados os critérios de elegibilidade e exclusão, foram selecionados 22 artigos para análise, sendo 9 indexados na base de dados BVS e 13 na SciELO. Constatou-se que os CS são ferramentas de estratégia essenciais, se apresentando como um canal direto entre a população e o desenvolvimento do SUS, contudo, mesmo que em alguns municípios a atuação deles esteja sendo desenvolvida em sua totalidade, alguns municípios não abarcam todas as atribuições que são direito da população. As dificuldades encontradas pelos conselhos envolvem uma série de causas, que vão desde o simples desinteresse pelas questões relativas dele, até questões mais complexas, como falta de comunicação entre a gestão e comunidade, infraestrutura indevida e falta de recurso financeiro. Dessa forma, estudos que discutam a participação dos CS como estratégias para participação popular no SUS são necessários para a construção de novas estratégias que possam tornar o planejamento e participação mais efetivas, atuantes e possíveis de serem realizadas em todo o país.

Este estudo descreve o processo de criação e montagem de um sistema para aquisição de dados de diâmetro à altura do peito de forma automatizada. A construção do protótipo móvel contou com os seguintes componentes: Arduino Pro mine, Módulo Cartão Micro SD, Sensor de Distância, Display LCD e Módulo Joystick. A montagem do sistema foi realizada em recipiente de plástico transparente. A validação dos dados foi feita por meio da comparação dos valores de diâmetro à altura do peito coletados com a suta convencional e o protótipo construído, por meio de medidas frontais e laterais de um plantio de Eucalyptus grandis. Os resultados demonstraram correlação linear positiva entre os dados obtidos pelo método convencional, utilizando suta mecânica e os dados obtidos atrás do protótipo confeccionado. O coeficiente de correlação de Pearson foi de 0,92 e 0,91 para as medidas frontal e lateral, respectivamente. O projeto se mostra viável para o uso dentro do setor florestal, principalmente em razão do baixo custo para confecção. No entanto, o protótipo apresentado necessita de maiores ajustes, principalmente em sua estrutura, a fim de facilitar o manuseio.

The objective of this work was to evaluate the physical, mechanical, and wood machining properties of 10 clonal progenies with 12 years of age aiming to produce furniture. A total of 10 progenies and three trees per progenies were used, totalling 30 trees analyzed. The basic density ranged from 0.404 g.cm-3 (IAC 301) to 0.495 g.cm-3 (IAC 326), being it considered a light wood. The anisotropy coefficient values ranged from 1.05 (IAC 40) to 1.68 (PB 330) considered low to medium dimensional instability allowing the use of wood to produce furniture with low dimensional movements. In the compression test most clones fall under class C30. For MOR and MOE, it was observed greater values for IAC 326 (11666 MPa) and GT1 (9575 MPa). In wood machining tests, slightly raised large and few defects on the surface, being them considered easy to work. The results obtained for Hevea brasiliensis, 12 years old, allow us to affirm that wood from a younger age is an alternative for furniture production and will consequently contribute to the reduction of the exploitation and degradation of native forests in Brazil for this purpose.
