Diffusion-mediated chemical concentration variation and void evolution in ion-irradiated NiCoFeCr high-entropy alloy
Authors: Fan Zhe , Zhong Weicheng , Jin Ke , Bei Hongbin , Osetsky Yuri N. , Zhang Yanwen
Published: February 2021

High-entropy alloys (HEAs) are proposed as potential structural materials for advanced nuclear systems, but little is known about the response of matrix chemistry in HEAs upon irradiation. Here, we reveal a substantial change of matrix chemical concentration as a function of irradiation damage (depth) in equiatomic NiCoFeCr HEA irradiated by 3 MeV Ni ions. After ion irradiation, the matrix contains more Fe/Cr in depth shallower than ~900–1000 nm but more Ni/Co from ~900–1000 nm to the end of the ion-damaged region due to the preferential diffusion of vacancies through Fe/Cr. Preferential diffusion also facilitates migration of vacancies from high radiation damage region to low radiation damage region, leading to no void formation below ~900–1000 nm and void formation around the end of the ion-damaged region at a fluence of 5 × 1016 cm−2 (~123 dpa, displacements per atom, peak dose under full cascade mode). As voids grow significantly at an increased fluence (8 × 1016 cm−2, 196 dpa), the matrix concentration does not change dramatically due to new voids formed below ~900–1000 nm.
Probing structural and chemical evolution in (AlxGa1−x)2O3 using atom probe tomography: A review
Authors: Mazumder Baishakhi , Sarker Jith
Published: February 2021

(AlxGa1−x)2O3 is a novel ultra‐wide bandgap semiconductor with the potential to dominate future power electronics industries. High‐performance devices demand high Al content in (AlxGa1−x)2O3 but are limited by crystallinity degradation resulting from phase separation. Additionally, the solubility limit of Al is still under debate, and conclusive research is in progress. (AlxGa1−x)2O3 is also limited in high‐frequency applications owing to low carrier mobility and requires n‐type doping. For commercializing this material, the major obstacle is understanding dopant's behavior in the host (AlxGa1−x)2O3. To investigate these issues, an advanced characterization technique, atom probe tomography (APT), was employed to analyze the structural‐chemical evolution of (AlxGa1−x)2O3. In this review, we summarized our recent works on the structure‐chemistry investigation of (AlxGa1−x)2O3 with alloy composition and doping interaction. We introduced machine learning algorithms on APT data to reveal unrivaled knowledge, previously not achievable with conventional methodologies. The outstanding capabilities of APT to study (AlxGa1−x)2O3 with Al composition and doping will be considered significant for the wide bandgap semiconductors community.
A review on the recent advances concerning the fatigue performance of titanium alloys for orthopedic applications
Authors: Campanelli Leonardo Contri
Published: February 2021

This article presents a review on recent advances in the fatigue behavior of Ti alloys, especially the main commercial compositions for orthopedic applications. In the case of well‐known Ti–6Al–4V alloy, the major concern is related to the effect of the surface modification necessary to improve the osseointegration. The introduction of surface discontinuities due to the growth of a porous oxide layer, or the roughness development, may severely affect the fatigue performance depending on the level of alteration. In the case of additive manufactured Ti–6Al–4V, the fatigue response is also influenced by inherent defects of as‐built parts. Regarding the recently developed metastable β alloys, information about the fatigue properties is still scarce and mainly related to the effect of second phase precipitates, which are introduced to optimize the mechanical properties. The fatigue behavior of the Ti alloys is complex, as is their microstructure, and should not be neglected when the alloys are being developed or improved to be applied in medical devices.
VIGOREXIA EM PRATICANTES MASCULINOS DO TREINAMENTO DE FORÇA ENTRE 18-35 ANOS
Authors: Oliveira Fernando Sérgio
Published: February 2021

O presente estudo teórico buscou aferir a incidência da Vigorexia entre praticantes masculinos do treinamento de força entre 18-35 anos. Nos últimos anos foi diagnosticado um transtorno majoritariamente associado ao sexo masculino chamado Dismorfia Muscular ou Vigorexia que, entre outros aspectos, perturba a vida social, física, mental e psicológica do indivíduo. Essa síndrome caracteriza-se por um quadro onde o indivíduo se vê com um corpo fraco, franzino e pequeno, mas que na verdade não corresponde à realidade, pois sua percepção visual está equivocada. Na verdade, ele é portador de um corpo musculoso, volumoso. Assim, este transtorno se caracteriza por uma exacerbada preocupação em ter o corpo com a maior massa muscular possível. Esta síndrome acomete principalmente os homens jovens, entre 18-35 anos, que buscam no treinamento de força uma “arma” para alcançar o corpo sonhado. A Vigorexia tem muitas causas e ainda não todas esclarecidas, mas é universalmente aceite pelos autores a extraordinária influência da mídia sobre este novo conceito de biótipo físico masculino. Os jovens buscam uma afirmação social através do corpo. Para tal, utilizam substâncias perigosas para a sua saúde como os esteroides anabolizantes. Ao mesmo tempo praticam sessões de treinamento exaustivas na ânsia de obterem músculos maiores levando o corpo à exaustão, além de prejudicarem ossos, ligamentos, tendões e músculos. Outro aspecto muito importante deste transtorno é o psicológico do indivíduo, muito alterado e frequentemente ansioso, principalmente quando associado à utilização de esteroides anabolizantes. Conclui-se no estudo que o problema é crescente e já com uma incidência respeitável e merecedora da atenção dos órgãos públicos para combater este problema.  Palavras-chave: Dismorfia Muscular. Imagem Corporal. Treinamento de Força. Mídia. Esteroide Anabolizante.

INTRODUÇÃO: O Stand Up Paddle (SUP) ou Hoe He’e Nalu, em havaiano, é um esporte que consiste basicamenteem remar de pé sobre uma prancha. Surgiu no Havaí, por volta de 1960, por surfistas, usavam grande pranchas e remavam nelas, para tirar fotos dos alunos e aspirantes do Surf da época. Mesmo sendo umesporte antigo entrou em evidência há poucos anos, tem como objetivo realizar uma revisão da literatura sobre aspectos atuais e relevantes deste esporte. MATERIAIS E MÉTODOS: Para este trabalho, foi realizada uma pesquisa na base de dados PubMed, em maio de 2018, utilizando como palavra-chave Stand Up Paddle. RESULTADOS: Foram encontrados 09 artigos sobre este tema, sendo todos originais. Dos artigos encontrados: 02 abordavam sobre lesão de praticantes do esporte, 02 artigos tratavam sobre a fisiologia do exercício, com praticantes e atletas de SUP, sobre postura, foram encontrados mais 02 artigos, também foram encontrados 02 artigos que abordavam a composição corporal e apenas 01 artigo, que não é relacionado ao esporte SUP,mas apareceu na pesquisa do banco de dados, bem provavelmente por apresentar a palavra “stand” e “paddle”. CONCLUSÃO: Conclui-se com esse trabalho que existem poucas pesquisas sobre o esporte SUP, cadastradas no banco de dados do Pubmed, mostrando a necessidade de mais estudos sobre as diversas áreas da saúde, para conhecer e compreender a fisiologia, a biomecânica, as lesões e dentre outros desse esporte. Se comparado esse esporte com outros esportes de remo, o SUP é o único que é praticado em pé.

Published: February 2021

The paper explores the perceptions of university students and their desired features on the use of blockchain technology for the management of education records. A literature review forms the theoretical basis of the research allowing to explore how education records are managed nowadays and the potential for the use of blockchain technology in this area. The theoretical framework is then used to discuss the research findings. The research adopts the interpretive qualitative approach and collects data through a focus group interview with university students. Computer assisted thematic data analysis yields five key themes: current usage of university education records, understanding how blockchain works, sustainability of blockchain, security of blockchain and implementation of blockchain for education records. Participants were generally positive towards the use of blockchain for the management of education records and saw it as one of the potential future solutions. Nevertheless, they voiced some reservations regarding the high energy consumption, costs and security towards a possible use of the blockchain technology. Therefore, careful implementation would be needed, with increased focus on usability, solving some security and sustainability issues and ensuring a fair and transparent access model.This research contributes to the current body of knowledge within informatics by empowering students to share their perception of possible development of student record systems based on blockchain technology. It also provides insights which can be used in the future to achieve a more user focused design of education records management systems.

Published: February 2021

Objetivou-se avaliar a relação entre o consumo de alimentos fora de casa e alterações em biomarcadores de doenças crônicas em adolescentes brasileiros. Trata-se de um estudo transversal em que foram utilizados os dados do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA), conduzido com 36.956 adolescentes, em 2013/2014. A relação entre consumir alimentos fora de casa e cada desfecho de interesse (hipertrigliceridemia, hipercolesterolemia, hiperglicemia, elevada hemoglobina glicada e hiperinsulinemia) foi testada por modelos de regressão logística ajustados por idade, rede de ensino da escola, atividade física e tempo de uso de telas. Dados de consumo alimentar foram obtidos pela aplicação do recordatório referente às 24h anteriores (R24h), analisando o consumo de energia, açúcar de adição, sódio, potássio, fibras, frutas, verduras, arroz, feijão, sanduíches, bolos, sobremesas, chocolates e refrigerantes. Foi encontrado que 53,2% dos adolescentes consumiam alimentos fora de casa. A alimentação fora de casa apresentou relação inversa com hiperinsulinemia (OR = 0,65; IC95%: 0,46-0,92) e hiperglicemia (OR = 0,46; IC95%: 0,30-0,71), entre meninos, e hipertensão (OR = 0,71; IC95%: 0,55-0,92) e hiperglicemia (OR = 0,57; IC95%: 0,34-0,96), entre meninas. Entretanto, o consumo de calorias, açúcar de adição, sanduíches, sobremesas e refrigerantes foi maior nos adolescentes que consumiam alimentos fora de casa. O papel protetor da alimentação fora de casa em indicadores bioquímicos nos adolescentes pode ser em função de um maior consumo da alimentação escolar, mais frequente entre os adolescentes que consumiam alimentos fora de casa, destacando a importância do estímulo ao consumo da alimentação escolar.

ABSTRACT: Hepatozoonosis is caused by protozoa of the genus Hepatozoon. In dogs, the infection is caused mainly by Hepatozoon canis, and there are a few descriptions of the prevalence of this infection in the Northeast region of Brazil, especially in the semi-arid region. Therefore, we aimed to determine the prevalence of Hepatozoon canis infection in dogs in the rural area of Sousa, Paraíba, Brazil, as well as to determine the possible clinical and epidemiological aspects of this infection. Ninety-eight dogs in the rural zone of the municipality of Sousa that were at least 4 months old were evaluated, regardless of their breed or gender. Clinical examinations were carried out, and samples of systemic and peripheral blood were collected to determine the presence of the parasite in blood smears and carry out hemograms. In addition, epidemiological questionnaires about animal health and food management were completed. The prevalence of H. canis infections in dogs was 8.1% (8/98). There were three main changes in the hematological status: thrombocytopenia, anemia and hyperproteinemia, mainly related to percentage of leukocyte infection ≥5%, and also to the presence of clinical signs such as mucopurulent secretion, lymphadenomegaly, dry skin, pale mucous membranes, and lean or cachectic body score.

ABSTRACT Objective To verify the multivariate relationships between eating habits, cardiorespiratory fitness, body mass index, and cardiometabolic risk factors in children. Methods This is a cross-sectional study developed in a public elementary school with 60 first- to sixth-graders. Their eating habits were assessed using the Food Frequency Survey, weight, height, and cardiorespiratory fitness, assessed according to the Projeto Esporte Brasil protocol. Moreover, the variables, high-density lipoprotein, low-density lipoprotein, glucose, insulin, C-reactive protein, adiponectin, leptin, diastolic and systolic blood pressure were evaluated. Descriptive statistics were used for data analysis and generalized estimation equations were used for the analysis of direct and indirect relations, in a multivariate analysis model with several simultaneous outcomes. Results It appears that the eating habits and cardiorespiratory fitness explain 20% of the body mass index. Cardiometabolic risk factors are explained by the relationship between eating habits, cardiorespiratory fitness, and body mass index, according to the following percentages: 29% (systolic blood pressure), 18% (diastolic blood pressure), 63% (leptin), 4% (adiponectin), 14% (C-reactive protein), 17% (insulin), 10% (high-density lipoprotein), 1% (low-density lipoprotein), 4% (glucose). It is also observed that the effects of the eating habits on cardiometabolic risk factors are indirect, that is, they are dependent on changes in the body mass index and cardiorespiratory fitness levels. Conclusions The relationship between eating habits and cardiometabolic risk factors in children is dependent on cardiorespiratory fitness and body mass index. Thus, our findings suggest a multivariate relationship between these factors.

Quando nos deparamos com problemas de mecânica, muitas vezes somos guiados por um senso de familiaridade e de analogias com situações prévias. No entanto, esta nem sempre parece ser uma boa alternativa. Ao contrário, há situações em que a simples analogia com situações parecidas nos conduz à resposta errada e a demonstração experimental se faz necessária para o entendimento do problema. Apresentamos neste trabalho uma destas situações. em que a falta de conhecimento sobre o comportamento de queda de um sistema massa-mola pode ser o motivo da dificuldade de alunos de nível médio e superior acerca da situação proposta.

Published: February 2021

Abstract: Introduction: The World Health Organization defined the compulsory need to redirect all educational, research and public health service activities of medical schools to meet all priority health needs, attributing to them this social responsibility role. Due to the emergency situation in the public health system caused by the COVID-19 pandemic, as a measure of social accountability, remote medical care services and online education were adopted in order to continue following the curricular program and to provide assistance to local city governments. Experience report: Two months before graduation, medical students followed-up on the monitoring of residents and COVID-19 healthcare professionals of forty-three ILPIs (Long-Term Elderly Care Facilities) in the city of Sao Jose do Rio Preto, state of Sao Paulo, Brazil. The medical students made daily telephone calls to all these ILPI units, requesting information, generally from the head nurses and owners, about the main COVID-19 symptoms that were detected in the residents and employees of these facilities. All the collected information was discussed daily with the teacher in charge of mentoring the program, fed into an online database and into a work schedule chart, then relayed to the local Municipal Health Secretariat. A COVID-19 contingency plan was devised by the team, authorized by the Local Health Secretariat and then presented to the ILPIs, aiming to offer them the best guidance throughout the pandemic. Discussion: the COVID-19 pandemic revealed the Health Education System’s fragilities, limitations and capacity to adapt to this crisis, thus largely contributing to improving the training of new medical doctors. During the program, medical students faced many challenges, especially regarding the difficulty to contact some ILPIs by telephone, omitted or erroneous information provided by employees in these facilities and delays in reporting suspected cases. In spite of this scenario, daily contact with these facilities allowed the team to identify the ILPIs that were more adequately prepared and the ones that needed auditing and further supervision. Also, this daily contact established a bond between the team and the ILPIs. Conclusion: During the pandemic, it was possible to perform actions according to the logic of social accountability, demonstrating that remote online medical practice is a tool capable of both maintaining interns in contact with the practical aspects of medical care and providing medical assistance to the community and to the local government.

Abstract: Introduction: The challenges brought by the continuity of the university teaching-learning process in the face of the measures to combat the pandemic of COVID-19 made the debate on the use of information and communication technologies (ICT) in medical education more important. Several strategies were used by teachers worldwide to continue their teaching activities. Objective: to investigate the strategies and uses of ICT in medical education in the face of the COVID-19 pandemic. Method: Five databases were systematically assessed, using the terms “COVID-19”, “medical education”, “higher education” and “students”, in Portuguese, English and Spanish, resulting in 321 initial citations, with 18 final references after applying the inclusion and exclusion criteria. Result: Four key topics were identified in the literature: (1) Challenges for Medical Education prior to COVID-19; (2) Challenges in migrating to remote education; (3) Strategies to overcome challenges related to the learning environment; and (4) Strategies to overcome challenges related to assessments and exams. Conclusion: The use of ICT in medical education in the context of the COVID-19 pandemic showed to be especially important, with considerations regarding the improvement in areas that were already used, the migration of some more articulated areas and experiences in clinical and procedural disciplines. There was also concern about the impacts of using ICT to replace the in-person presence of students in medical learning environments.

Published: February 2021

Abstract The literature highlights the existence of weaknesses in the psychosocial care network, especially in the treatment of children and adolescents that use drugs. The study aimed to comprehend, based on the Winnicottian theoretical framework, how a Residential Care Unit has been providing care to children and adolescents with needs arising from drugs use in situations of social vulnerability. Semi-structured interviews, with eight care providers, and 65 hours of participant observation were carried out. From the thematic analysis, three themes were constructed: (1) Setting: regarding attention to basic needs and construction of a routine; (2) View: regarding empathy and expansion of perspectives; (3) Aggressiveness: regarding new ways of relating. Important actions are aimed at constructing care for this specific population, as this is a current theme with recent and weakly structured public policies.

ABSTRACT Objective: To describe two cases of unusual variants of sickle cell disease. Case description: We present two cases of sickle cell disease variants (haemoglobinopathies), from unrelated families, in the state of Balochistan (Pakistan). One was diagnosed with sickle cell disease in the haemoglobin electrophoresis, whereas the other was diagnosed with sickle cell SE disease. Both were diagnosed based on the presentation of osteomyelitis. Comments: Haemoglobin SD disease (Hb SD) and haemoglobin SE disease (Hb SE) are rare haemoglobinopathies in the world. The lack of available literature suggests that both are variants of sickle cell disease (SCD), with heterogeneous nature. The prevalence of sickle cell disease with compound heterozygotes was found at a variable frequency in the population of the Asian Southeast. The frequency of osteomyelitis in SCD is 12 to 18%, but its occurrence among variant haemoglobinopathies is little reported. Both reported cases presented with osteomyelitis as a characteristic of the disease presentation.
Panorama da disposição de resíduos sólidos urbanos e sua relação com os impactos socioambientais em estados da Amazônia brasileira

Published: February 2021

Resumo Países europeus tais como Alemanha, França, Dinamarca e Reino Unido possuem tecnologias e políticas de resíduos sólidos que buscam elevados índices de reaproveitamento, diminuindo significativamente a necessidade de envio aos aterros sanitários. Assim, o objetivo deste estudo foi realizar o diagnóstico das condições dos resíduos sólidos urbanos (RSU) e relacionar com os impactos socioambientais em sete estados da Amazônia brasileira. A pesquisa tem caráter descritivo, baseada em dados secundários, obtidos através de pesquisas bibliográficas e documentais, coletados em plataformas eletrônicas. Observa-se então que a Amazônia, mesmo com a exploração ativa de seus recursos naturais e potencial econômico, não alcança o restante do país no que diz respeito à longevidade, educação e renda, inferindo que a exploração não traz as benesses esperadas em termos de qualidade de vida para a população local. Outra problemática é o déficit nos registros de municípios que alimentam os dados no Sistema Nacional de Informações sobre Saneamento (SNIS), demonstrando que a geração de RSU ultrapassa os valores aqui apresentados, pois menos da metade dos municípios da Amazônia presta esse serviço informacional obrigatório, seja prestador público ou privado. Nesse sentido, há a necessidade de mudança no paradigma de gerenciamento de resíduos.
Distribuição de investimentos públicos, infraestrutura urbana e desigualdade socioespacial em Curitiba

Published: February 2021

Resumo Este artigo tem como objeto a distribuição espacial de recursos públicos em infraestrutura urbana e sua relação com a dinâmica imobiliária e as desigualdades socioespaciais, tomando como caso de estudo a cidade de Curitiba. Inicialmente, o espaço intraurbano foi mapeado conforme níveis de precariedade segundo as condições dos domicílios, serviços públicos urbanos, infraestrutura, renda e oferta de transporte público. Em seguida, foi analisada a distribuição espacial dos investimentos realizados pelo poder público municipal em obras públicas entre 2005 e 2016, mais especificamente em pavimentação, edificações, iluminação pública, pontes e drenagem. Por fim, a partir da introdução de elementos referentes à atuação imobiliária, procurou-se confrontar a configuração das intervenções públicas urbanas com o comportamento do mercado imobiliário e com as demandas sociais. Ficou evidenciado que as precariedades também se manifestam na repartição diferencial de recursos em obras públicas que, ao invés de contribuir efetivamente para a justiça social, reforçam a distribuição desigual dos benefícios e ônus da urbanização.
Functions of Collective Narratives in a Territorial Conflict. The Israeli-Palestinian Case
Authors: Lobera Josep , Torres-Albero Cristóbal
Published: February 2021

ABSTRACT The various narratives of a conflict play a central role in its development. Not only are they a reflection of the collective memory of the various parties in conflict, but also a functional element in its dynamics. In the case of the Palestinian-Israeli conflict, data show that each side’s main narratives are fairly stable over time, and they possess significant magnitudes – over two thirds of their publics, in both cases. This article analyses the use of narratives in the dynamics of the conflict, which affects both the cognitive and emotional dimensions of the public’s worldview on both sides. We draw ten main functions of collective narratives in the conflict. We discuss that, although a transformation of narratives in the conflict is required for its resolution, both groups will face resistance associated with the functionality of the narratives during this process.

DESIGN AND DEVELOPMENT OF AN LADM-BASED EXTERNAL DATA MODEL FOR LAND REGISTRY AND CADASTRE TRANSACTIONS IN TURKEY: A CASE STUDY OF TREASURY REAL PROPERTIES
Authors: Alkan Mehmet , Arslan Elif Taş
Published: February 2021

Abstract: The processes starting with the identification and registration of treasury properties have an essential place in the cadastral systems. Spatial data modelling studies were conducted in 2002 to establish a common standard structure on the fundamental similarities of land management systems. These studies were stated as a beginning named Core Cadastral Domain Model (CCDM), since 2006, it has been started to be made under the name of LADM. This model was accepted in 2012 as a standard model in the field of land administration by the International Organization for Standardization (ISO). In this study, an external model class is proposed for LADM’s transactions related to Treasury’s real estates properties which are related National Property Automation Project (MEOP). In order to determine the deficiency of this current external model, databases containing records related to spatial data and property rights were examined, and the deficiencies related to transactions on treasury properties were determined. The created external class is associated with the LADM’s LA_Party, LA_RRR, LA_SpatialUnit and LA_BAUnit master classes. Herewith the standardization of the external data model is ensured. If the external model is implemented by the responsible standardization of the archiving processes will be more comfortable and faster to register.
The lubrication performance and viscosity behavior of castor oil under high temperature
Authors: Zeng Qunfeng
Published: February 2021

Castor oil is an environment-friendly lubricant with good biodegradability and renewable behavior. However, castor oil as a green lubricant has a few shortcomings, such as a low viscosity index and low oxidative stability due to the presence of unsaturated bonds. The temperature affects the lubrication performance of castor oil. In the present study, the lubrication performance and viscosity behavior of castor oil lubricating the friction pair of a steel ball and a nickel–titanium (NiTi) alloy disk were systematically investigated under different temperatures. The results show that the lubrication performance of castor oil is influenced by temperature due to the fact that the viscosity of castor oil varies with the temperature. The coefficient of friction (CoF) of castor oil is as super-low as 0.076 at a temperature of 40°C, but is relatively high at other temperatures. The factors affecting the lubrication performance were investigated, and a possible antifriction mechanism is proposed in this study.
Partnerships in action: establishing a model of collaborative support to student and mentor teachers through a universityschool partnership
Authors: Silbert Patti , Verbeek Clare
Published: February 2021

South African universities have a crucial role to play in helping reduce inequalities in schooling by preparing teachers for working across diverse school contexts. This article examines a pre-service teacher collaborative support programme generated through a twoyear action research process. The programme was designed to support student teachers and their school-based mentors during Teaching Practice through an existing university-school partnership. Using a qualitative analysis of journal entries and separate focus group discussions with student and mentor teachers we describe students’ and mentors’ responses to the collaborative support programme. The findings of the study suggest that a collaborative support strategy pitched at both the university and school is critical to support student teachers during their pre-service teaching, especially in socially and educationally challenging contexts. Joint responsibility for initial teacher development requires a reconceptualisation of the role of the mentor teacher, and a shift towards the distribution of mentoring functions from a few designated mentor teachers to include a wider range of teachers at the school.
Birds crossing over roads: species, flight heights and infrastructure use
Authors: Jacek Betleja , Jankowiak Łukasz , Sparks Tim H. , Tryjanowski Piotr
Published: February 2021

How high do birds fly above roads, and how do they use the road infrastructure (bridges, lampposts etc.)? These questions are rarely explored in ecological studies but were addressed by us during research in 2016–2018 in southern Poland. In total, 1665 individual birds belonging to 24 species were recorded. Species differed significantly in the height at which they crossed over roads, but about 30% of all crossings were at heights below 12 m, hence at potential collision heights. The proportion of birds perching on lampposts in the central reservation between carriageways also differed significantly between species. The surrounding landscape and road infrastructure, especially lampposts, modified the species composition associated with roads. This knowledge has practical importance, not only in regard to collisions, but also to much less studied aspects such as plant seed dispersal and/or corrosion of the infrastructure. Lampposts, as a taller component of the infrastructure, may not directly affect vehicle-bird collisions, but a flight to them may be a risky business, and we recommended higher lampposts to discourage low-level flights. This information may need to be incorporated into future studies on road ecology, as well as in mitigation programs.
Analysis of the experience of performance contracting development in Russia
Authors: Izmaylov Maxim K.
Published: February 2021

Importance. To date, performance contracts in terms of modernization and management of fixed assets are practically not used in the economy of the Russian Federation and, in particular, at the level of industrial enterprises. The entire experience of developing performance Contracting in Russia is directly related to energy service contracts. At the same time, the existing potential to reduce energy consumption and increase energy efficiency makes it possible to use the performance Contracting mechanism in Russia today. The successful development of performance Contracting in the energy sector allows us to make a reasonable conclusion about the possibility of its use in other non-energy sectors, and in particular in the process of managing the fixed assets of industrial enterprises. The proposed approach to the use of performance Contracting in the management of fi xed assets of industrial enterprises is based on the idea that the contractor under such a contract assumes all the risks of introducing new fi xed assets in real production. Objectives is to analyze the problems of performance Contracting development in Russia and develop recommendations for its development. Methods. In the process of achieving these goals, the following methods of scientific knowledge were used: dialectical; analysis and synthesis. The research is based on the study of current scientific and periodical economic literature. Results. A brief history of the formation and development of energy service contracts is given. The main statistical data that characterize the development of the performance Contracting market in Russia at the current stage are reflected. Conclusions. Based on the conducted research, the necessity of using performance Contracting in the management of fixed assets of industrial enterprises is justified. The final part of the article presents the main reasons that hinder the mass development of performance Contracting in Russia,as well as some recommendations for its development. The conclusion is based on the need to continue work on the introduction of incentive mechanisms for industrial enterprises in the field of performance contracts for financing projects and activities to update and modernize basic funds, as well as to improve their energy efficiency, which will allow attracting new investments in energy conservation and ensure the return of invested funds by saving financial resources.

Introduction: Diabetes is defined as a disturbance in intermediary metabolism manifesting aschronic sustained hyperglycemia, primarily due to either an absolute or a relative lack of insulin.Many epidemiological studies have demonstrated an inverse relationship between vitamin D levelsand diabetes mellitus. However, there is a paucity of literature regarding the levels of vitamin D intype 2 diabetes, which is common in our community. This study was taken up to shed more light onthis issue. Material and methods: This was a cross-sectional study conducted at NRI Institute ofMedical Sciences, Sangivalasa, Visakhapatnam district. Cases of Type 2 Diabetes Mellitus attendingto the outpatient department, diagnosed as per the ADA criteria of 2011, between the ages of 31and 75 years constituted the material for the present study. Results and conclusion: Vitamin Dlevels were found to be significantly lower in the study group (19.91±7.0 ng/ml) as compared to thecontrol group (32.22±4.0 ng/ml).
El Mago (de) Matthew Barney: Influencias Renacentistas en el Ciclo Cremaster
Authors: Sirbu Anca Luiza
Published: February 2021

In this article we will try to offer a new interpretation of the video art work of the artist Matthew Barney (California, 1967) the Cremaster Cycle, approaching a more humanistic and less biological vision, the last one being the principal study aspect for the experts on Matthew Barney. We will focus on the character of the Magician, a key figure in the Cremaster Cycle. The Magician lighting the pass to a possible interpretation of the Cycle in Renaissance key, the magician character while being a personification of aesthetic- artistic interests of Matthew Barney is also an approximation to the ideal of the Renaissance man: philosopher, magician, healer. Alter-ego of Matthew Barney, the escape artist Harry Houdini represents (and through him all other magical branches) a possible link with the powerful magician Renaissance described by the philosopher Giordano Bruno (1548-1600), able to metamorphose, influence in the sensitivities of his objects, through self-knowledge and knowledge of the Divine.
Arte y Ciencia para un Paisaje en Crisis: Caso de Estudio del Proyecto Cartografías de la Metamorfosis
Authors: Ortuño Pedro
Published: February 2021

Based on Ehrenfried Pfeiffer's method of sensitive crystallization, the Cartographies of Metamorphosis artistic project exposes the vitality, in the form of mandala graphics, of the different horticultural products from Campo de Cartagena, a method that makes the intrinsic quality of the material visible organic. In 2016, the Mar Menor landscape collapsed for the first time and accentuated its state of environmental crisis, due in part to the dumping of large amounts of organic matter and nutrients of various kinds, but especially from agricultural and livestock activities. Made in the context of the environmental crisis of the Mar Menor, the sculptural and audiovisual installation metaphorically reflects on the new geological era coined by Paul Crutzen and the eutrophication landscape around the lagoon.

Azocoupling Reaction Of Cephalosporin Antibiotics With 8-Hydroxyquinoline And Its Application In The Analysis Of Medicinal Products
Authors: Kostiv O. , Korkuna O. , Ornat M.
Published: February 2021

Methods for spectrophotometric determination of cephalosporin antibiotics ceftazidime and ceftriaxone using azocoupling reactions with 8-hydroxyquinoline have been developed. Optimal conditions for the diazotization of antibiotics in hydrochloric acid (CHCl = 12 M) and subsequent azocoupling with 8-hydroxyquinoline in alkaline medium (0.16 M NaOH in the final volume) were established. The of azocopling products of violet and light red colors are formed, which are characterized by absorption maxima at 553 nm (ε553 = 6.31·103 M-1 cm-1) and 550 nm (ε550 = 1.45·104 M-1 cm-1) for ceftazidime and ceftriaxone, respectively. Stoichiometric ratios of the azo compounds components were determined using continuous variations methods and in both cases are 1:1. Sensitive methods of spectrophotometric determination of ceftazidime (LOD = 1.81∙10-6 M) and ceftriaxone (LOD = 5.92·10-7 M) have been developed. The selectivity of cephalosporin antibiotics spectrophotometric determination in the presence of auxiliary substance (sodium carbonate) has been investigated. The elaborated methods has been approved during the analyses of model solutions and the single component drug. The recommended procedure is well suited for the ceftazidime and ceftriaxone assay in medicine to assure high standards of quality control.

Authors:   Institute of Engineering Science, Ural Branch of the Russian Academy of Sciences, Vandyshev A. B.
Published: February 2021

Mathematical simulation is used to analyze systematically the results of testing an individual disk-type membrane-catalytic module for producing high-purity hydrogen from methane, with a capacity of about 0.3 m3H2/h, and the design data of a membrane-catalytic reactor based on 32 individual disk-type modules for producing high-purity hydrogen from diesel fuel, with a capacity of 7.45 m3H2/h. The used mathematical model adequately and on a good quantitative level describes the experimental and design data known from the literature. In terms of the used model representations, possible ways of increasing both the capacity of disk-type membrane-catalytic devices and the efficiency of extracting high-purity hydrogen from the original hydrocarbon material are considered.
