The Conceptual Framework Modelling the Causality Effect Between Instafamous Credibility and Entrepreneur Action
Authors: Erina Ismail  , Mutia Sobihah Abd Halim
Published: November 2021

This paper aims to present a conceptual framework of causal effect between instafamous credibility on the entrepreneurial action among the university’s students who are an Instagram user. The conceptual framework was developed by a literature review of the social media influencer’s credibility construct i.e., the trustworthiness, expertise, and attractiveness and the entrepreneurial behavior (action). The understanding and predicting entrepreneur action are vital because it is understandable that becoming an entrepreneur is quite a complex process of planned behavior to endure by the student. It is, therefore, an opportunity for the stakeholders to explore the benefit of the advancement of social media platform, specifically the Instagram to develop an Instapreneur. The entrepreneur action and source credibility framework will allow us to better understand the impact of various business emergence and identifying what and how it emerges.

Actual Aspects of Surgical Treatment of Dupuytren's Disease (Literature Review)
Authors: Naumenko L.Yu. , Kondrashova I.A.
Published: November 2021

Relevance. The variety of manifestations of Dupuytren's disease, caused by the degree of lesions of the palmar aponeurosis, the duration of the disease, the nature of professional activity, and concomitant pathology of patients, has led to the development of numerous surgical techniques with different levels of effectiveness in the acute and long-term periods. A wide discussion of the issues of Dupuytren's disease in the domestic and foreign periodicals, the analysis of treatment methods, complications and rehabilitation indicate the urgency of the problem and the expediency of further research.

Objective: a retrospective analysis of the leading literary sources devoted to the surgical treatment of Dupuytren's disease; the definition of modern approaches to surgical tactics and restoration of hand function.

Results. The analysis of literature sources showed the advantages of differentiated approaches to the surgical treatment of Dupuytren's disease, depending on the severity of the disease. With mild and moderate lesions, there is a significant increase in needle aponeurectomy. In severe forms, the segmental aponeurectomy technique is preferred over the total one. There is some discrepancy in carrying out surgical mobilization of the proximal interphalangeal joint and the need to achieve a functional position as a result of treatment. The tactics of surgical treatment and rehabilitation of Dupuytren's disease requires an individual approach, taking into account the age and severity of the disease, and tends to spread minimally invasive fasciotomy techniques.
Problematic Issues of the Theory and Practice of Finger Joints Endoprosthetics (Literature Review)
Authors: Mametiev A.O. , Naumenko L.Yu.
Published: November 2021

Summary. The proximal interphalangeal and metacarpophalangeal joints play an important role in the function of the hand as an organ of labor and self-care. The frequency of joint injuries of this localization reaches 32% in the structure of hand injuries, and unsatisfactory consequences are associated with the severity of the injury. Wrong treatment ranges between 60-80%, which gives ground to classify the problem as socially significant. The development and improvement of implant designs came through the introduction of new materials, structural changes in the fasteners and mobility. Much of the implants design became a thing of the past, giving a push to the development of new models. The need for anatomical and functional compliance of the implant with the characteristics of a healthy joint gave an impulse to research on the manufacture of individual prostheses with the help of 3D modeling. The analysis of literature sources showed a high level of unfavorable consequences of damage to the finger joints and the prospects for the development of more anatomical designs of hand joints prostheses. The development of individual geometrically similar designs endoprostheses of the finger joints of hand that will provide conditions of improvement of quality of treatment of patients remains an actual problem. The relatively short period of operational suitability of existing endoprostheses affected by a limited number of medical supervision necessitates the expansion of research in the near and long terms after prosthetics.
An experimental study of PMMA precision cryogenic micro-milling
Authors: Yan Ying , Sun Yujia , Li Bo , Zhou Ping
Published: November 2021

Polymethyl methacrylate (PMMA) has been used more and more widely in the fields of microfluidic devices and high-precision optical components due to its excellent mechanical and optical properties. Micro-milling is one of the methods that has been used in the machining of polymer materials. The machinability of PMMA is highly dependent on temperature, and the cryogenic method is also applied to control the processing temperature. In this work, the PMMA was milled with different processing parameters at the temperature of -55℃ and 25℃. The influence of each milling parameter on the surface quality under different temperature conditions were investigated. According to the results, the cutting depth is the dominant factor that influenced the surface roughness. The shape accuracy of the rectangular microgroove processed under low-temperature conditions is better. The material removal mechanism under different temperatures was also discussed, and the material is cut in a brittle way under low temperatures.
METHODS OF PROJECT-VECTOR MANAGEMENT OF EDUCATIONAL ENVIRONMENTS

Published: November 2021

Based on the developed mathematical model of the project-vector space, the methods of determining the endpoints of the objects of the project-vector space (PVS) and the calculation of the trajectory of the movement to these points are proposed. It is shown that the problem of developing these methods is related to the definition of such projects (project integration), which will correspond to the maximum expansion of “Universal Projects” educational environment. Calculation of the trajectory of the movement in the project-vector space ensures the achievement of the objectives of the project with minimal time and financial resources. It is proposed to use the Monte Carlo method to calculate the options for the trajectory of PVS subjects. This distribution of probabilities when choosing the displacement of objects and subjects of PVS corresponds to the priority of subjects and the impact of objects on the displacement of these subjects. For the assessment of the magnitude of the impact on the movement of PVS subjects it was developed the structure of the expert table and the model of the calculation of the average expert assessment of such an impact. Implementation of the given methods will allow to dynamically evaluate the most important goals for all interested parties of the project, as well as to develop ways to achieve them in real terms. In this case, the real conditions of the projects are described in the system of impact on the movement of objects and subjects of PVS in the expanding “Universal Projects”.
TASKS AND METHODS OF TEXT SENTIMENT ANALYSIS
Authors: Mukasheva А.
Published: November 2021

The purpose of this article is to study one of the methods of social networks analysis – text sentiment analysis. Today, social media has become a big data base that social network analysis is used for various purposes – from setting up targeted advertising for a cosmetics store to preventing riots at the state level. There are various methods for analyzing social networks such as graph method, text sentiment analysis, audio, and video object analysis. Among them, sentiment analysis is widely used for political, social, consumer research, and also for cybersecurity. Since the analysis of the sentiment of the text involves the analysis of the emotional opinions expressed in the text, the first step is to define the term opinion. An opinion can be simple, that is, a positive, negative or neutral emotion towards a particular object or its aspect. Comparison is also an opinion, but devoid of emotional connotation. To work with simple opinions, the first task of text sentiment analysis is to classify the text. There are three levels of classifications: classification at the text level, at the level of a sentence, and at the aspect level of the object. After classifying the text at the desired level, the next task is to extract structured data from unstructured information. The problem can be solved using the five-tuple method. One of the important elements of a tuple is the aspect in which an opinion is usually expressed. Next, aspect-based sentiment analysis is applied, which involves identifying aspects of the desired object and assessing the polarity of mood for each aspect. This task is divided into two sub-tasks such as aspect extraction and aspect classification. Sentiment analysis has limitations such as the definition of sarcasm and difficulty of working with abbreviated words.

Por meio de pesquisa bibliográfica, descritiva e investigativa do Ordenamento Jurídico Brasileiro, demonstra-se a importância dispensada à religiosidade e à crença pela Constituição brasileira e pela legislação infraconstitucional e a consequente autonomia da área do Direito que regula as relações dos fieis e da igreja em sociedade, especialmente na garantia de seus direitos.
O Poder Civil e a Obrigação de Consciência
Authors: P. R. Boeira Marcus
Published: November 2021

O presente artigo expõe uma breve reflexão em torno dos limites do poder civil relativamente à consciência humana. Para tanto, propõe uma articulação entre a liber-dade para ter condições de agir e a ação prático-moral, articulação esta que desponta co-mo tipologia-padrão da razão prática, além de critério objetivo suficientemente capaz de fundamentar uma ação política legítima, distinguindo-a da ação impolítica, tomada aqui como fenômeno no qual o poder não encontra limites objetivos e se expande para invadir esferas que não lhe competem. O critério definitivo que qualifica uma ação política como ancorada na prudência é o bem comum.
Loucuras Inofensivas
Authors: Madureira Jonas
Published: November 2021

O artigo apresenta uma argumentação sobre o papel da imaginação diante da ameaça das “imagens totalitárias”. A trama dos argumentos é constituída a partir da histó-ria do cidadão de Argos, contada por Erasmo de Rotterdam, e se desenvolve em dois blocos. No primeiro, explicita-se três distinções elementares: (1) imaginação e imagens prontas; (2) imaginação e equívoco; (3) imaginação e alucinação. Após as distinções, no segundo bloco, a argumentação concentra-se no papel da imaginação como uma potência que resiste às imagens prontas e aos esquemas mentais totalitários. Ao final, a crítica do sequestro da imaginação é feita à luz de alguns esclarecimentos das abordagens de Hannah Arendt e Paul Ricoeur, em especial, das abordagens referentes ao caráter homogeneizante e coletivista das ideologias.
A Laicidade no Debate Filosófico-Político Atual
Authors: Gonçalves Fernandes André
Published: November 2021

Em um ambiente político liberal no qual se fomenta vivamente um construtivismo politico (Rawls), as igrejas podem participar na esfera pública, porque a cultura religiosa pode iluminar certos aspectos vitais que, num contexto epistemologicamente cientificista, racionalmente instrumental e financeiramente economicista, restaram esquecidos, na medida em que as religiões não cessam de plasmar os modelos culturais das grandes civilizações (Habermas).
A Pretensa Neutralidade do Secularismo Público Posta à Prova

Published: November 2021

No contexto dos recentes debates no Supremo Tribunal Federal sobre a tese do abuso de poder religioso, o artigo aborda as seguintes questões: em que medida o capital social de ministros religiosos deve interferir na condu-ção do processo eleitoral? Qual o conteúdo do discurso religioso? Seria esse tipo de discurso propagado apenas por instituições confessionais e religiosas? Para resolver tais questões, o artigo parte de uma ampla revisão bibliográfica de obras dos principais expoentes de duas escolas de pensamento: a tradição neo-clássica do direito natural de John Finnis e a tradição reformacional em Herman Dooyeweerd. Verifica-se a hipótese da (in)consistência sociológica e moral da tese do abuso de poder religioso, sua pertinência em uma sociedade de múlti-plos discursos metanarrativos com fundo religioso (ainda que civil).

AbstractThis study discusses about the ethonographic approach in educational research. Ethnographic research, at first, was widely used in anthropological research, and developed in various fields of science such as medicine, health, psychology, and education and other social sciences. then, it can be concluded that there are four types of ethnographic research analysis in Spredley's model, they are: domain analysis, taxonomic analysis, compound analysis, and model analysis (ethnographic results. The qualitative research stages of the Spradley model consisted of 12 stages starting with determining a reliable or accurate key informant. Next, do an interview. Then, the researcher began asking descriptive questions, with an analysis of the interview. The results of the interview analysis, then the researcher conducted a domain analysis. In the next step, the researcher has determined the focus, and conduct a taxonomic analysis, then the researcher asks contrast questions, which are followed by a comparative analysis. The results of the comparative analysis, then the researcher found cultural themes. And the final step, the researcher wrote an ethnographic research report. And of course all of these stages must be adjusted to the field of education if research is in the field of education.Keyword: Ethnography Research, Ethnography Approach, Etnografi in Education.
FAST Discovery of a Long H i Accretion Stream toward M106

Published: November 2021

We report the discovery of a possible accretion stream toward a Milky Way–type galaxy M106 based on very deep H i imaging data with the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The accretion stream extends for about 130 kpc in projection length and it is similar to the Magellanic stream in many respects. We provide unambiguous evidence based on the stream morphology, kinematics and local star formation activity to show that the H i gas is being accreted onto the disk of M106. Such a long continuous flow of gas provides a unique opportunity to probe the circumgalactic medium (CGM) and reveals how the gas stream traverses the hot halo and CGM, and eventually reaches the galaxy disk. The source of the stream appears to be from M106's satellite galaxy NGC 4288. We argue that the stream of gas could be due to the tidal interaction with NGC 4288, or with a high speed encounter near this system. Close to the position of UGC 7356 the stream bifurcates into two streams. The second stream may be gas tidally stripped from UGC 7356 or due to an interaction with UGC 7356. Our results show that high-sensitivity H i imaging is crucial in revealing low column density accretion features in nearby galaxies.

L’émergence d’un cluster viticole chinois ou l’obsession de la domestication du vivant
Authors: Pétric Boris-Mathieu
Published: November 2021

La Chine, avec une superficie de plus 850 000 hectares, est devenue de manière fulgurante l’un des tout premiers vignobles mondiaux. Son développement s’appuie sur une politique de développement de cluster viticole. Le gigantesque projet du Yantai Changyu Wine International City est l’illustration d’une conception particulière chinoise d’une volonté de domestiquer à la fois le monde végétal et la conduite de ses citoyens. Ce vaste complexe œnotouristique est à la fois un espace de production, mais aussi un espace de consommation où les activités sont étroitement encadrées par la puissance publique. L’émergence de cette culture viti-vinicole singulière amène à s’interroger sur le rôle de la Chine dans la diffusion d’une domestication à l’échelle mondiale.
Des inspecteurs à la chaîne. Une gestuelle ouvrière, un geste politique
Authors: Gautier Amandine
Published: November 2021

Le travail d’inspection en abattoir demande une implication de tout le corps et une adaptation des gestes au rythme de la chaîne d’abattage. L’activité des agents chargés de l’inspection, dont les traits s’apparentent à une gestuelle ouvrière, contient cependant une forte dimension politique. Le geste, contraint par l’abattoir et ses caractéristiques, se trouve au cœur du pouvoir des agents publics et des possibilités de construction de leur identité professionnelle : l’inscription des corps de fonctionnaires sur les lignes d’abattage questionne ce qu’il reste de l’État. Cet article montre que le geste professionnel constitue une entrée de choix pour comprendre la signification que ces agents publics donnent à leur travail. En examinant les enjeux du geste et de ses adaptations aux contextes locaux dans le cadre d’une mission régalienne, il plaide en faveur d’une analyse multi-niveaux du geste professionnel.

Controlling an epidemiological model is often performed using optimal control theory techniques for which the solution depends on the equations of the controlled system, objective functional and possible state and/or control constraints. In this paper, we propose a model-free control approach based on an algorithm that operates in 'real-time' and drives the state solution according to a direct feedback on the state solution that is aimed to be minimized, and without knowing explicitly the equations of the controlled system. We consider a concrete epidemic problem of minimizing the number of HIV infected individuals, through the preventive measure pre-exposure prophylaxis (PrEP) given to susceptible individuals. The solutions must satisfy control and mixed state-control constraints that represent the limitations on PrEP implementation. Our model-free based control algorithm allows to close the loop between the number of infected individuals with HIV and the supply of PrEP medication 'in real time', in such a manner that the number of infected individuals is asymptotically reduced and the number of individuals under PrEP medication remains below a fixed constant value. We prove the efficiency of our approach and compare the model-free control solutions with the ones obtained using a classical optimal control approach via Pontryagin maximum principle. The performed numerical simulations allow us to conclude that the model-free based control strategy highlights new and interesting performances compared with the classical optimal control approach.

In this paper, firstly we define the concept of h-preinvex fuzzy-interval-valued functions (h-preinvex FIVF). Secondly, some new Hermite-Hadamard type inequalities (H-H type inequalities) for h-preinvex FIVFs via fuzzy integrals are established by means of fuzzy order relation. Finally, we obtain Hermite-Hadamard Fejér type inequalities (H-H Fejér type inequalities) for h-preinvex FIVFs by using above relationship. To strengthen our result, we provide some examples to illustrate the validation of our results, and several new and previously known results are obtained.

Likewise, a lot of examples are exposed under the invented measures based on PHF data in the environment of medical diagnosis to demonstrate the stability and elasticity of the explored works. Finally, the sensitive analysis of the presented works is also implemented and illuminated their graphical structures.
Avaliação da extensão universitária: o papel dos fóruns nacionais
Authors: Pontes Marina Piason Breglio , Rios Mônica Piccione Gomes
Published: November 2021

Este artigo estuda a avaliação da Extensão Universitária, no contexto do Sistema Nacional de Avaliação da Educação Superior (SINAES). A Extensão se fortaleceu nas IES brasileiras ao longo das décadas, como expressão de sua responsabilidade com a transformação social. Entretanto, o SINAES relega as atividades de Extensão a um segundo plano. Assim, tem-se como objetivo investigar o processo de avaliação da Extensão Universitária no âmbito dos fóruns nacionais, FOPROEX, FOREXT e FOREXP, à luz do Joint Committee on Standards for Educational Evaluation. A opção metodológica em uma abordagem qualitativa, inclui revisão da literatura, com análise documental dos fóruns nacionais. Constatou-se que o SINAES, enquanto política pública, demonstra fragilidade em subsidiar as universidades nesse campo, e que não há, no contexto dos fóruns, proposta que abarque a complexidade da Extensão Universitária, apesar do perceptível avanço em pensar uma avaliação coesa, útil e justa.
Medicalização da educação: problematizações e arquegenealogia a partir da “Revista de Educação” do estado do Espírito Santo (1934-1937)
Authors: De Oliveira Débora Nascimento , Bassani Elizabete , Ronchi Filho Jair
Published: November 2021

Este artigo é resultado de parte de uma dissertação de mestrado que objetivou problematizar a disseminação de discursos medicalizantes na educação infantil. O conceito de medicalização é apresentado segundo a perspectiva de autores como Foucault, Illich, Szasz, entre outros teóricos. O texto trata como essencial o conceito de discurso a partir de Foucault, desse modo desenvolvemos uma arquegenealogia, a qual consistiu em uma pesquisa documental que utilizou como monumento a “Revista de Educação”, publicada no estado do Espírito Santo entre os anos de 1934 e 1937. Selecionamos para análise matérias que explicitavam, em especial, o valor destinado às relações entre educação e saúde, enfatizando a hierarquia saber/poder da saúde sobre a educação, trazendo inúmeros preceitos higienistas que nos permitiram uma compreensão sobre como os referidos escritos disseminaram preconceitos e exclusões nos cotidianos escolares no estado do Espírito Santo.

Published: November 2021

O objetivo do estudo foi analisar a produção disponibilizada no Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior acerca do trabalho docente durante o primeiro ano da pandemia da Covid-19 no Brasil. Realizou-se uma pesquisa qualitativa, do tipo estado da arte, cujos resultados foram analisados conforme a técnica de análise de conteúdo proposta por Bardin (2016). Selecionaram-se 16 produtos, dos quais emergiram duas categorias temáticas: precarização do trabalho docente e ensino remoto emergencial. Constatou-se que: a precarização do trabalho docente está potencializada pela pandemia; a maioria dos professores não é capacitada para o ensino remoto emergencial; muitos alunos sofrem exclusão digital, aumentando ainda mais as desigualdades sociais e os desafios para os docentes. Concluiu-se que as repercussões da pandemia sobre o trabalho docente estão relacionadas à mitigação dos direitos trabalhistas e à exaustão física e emocional dos docentes para cumprir as novas demandas de trabalho.
Educação (Ambiental): moldando corpos para gerir a vida?
Authors: Oliveira Santos Luiz Ricardo
Published: November 2021

A Educação Ambiental (EA) estaria livre de vínculos institucionais e isenta das formas de governo existentes na sociedade? Mesmo baseada em ações necessárias à sustentabilidade ambiental, manifesta-se como um processo libertário? Este estudo objetivou problematizar a relação entre EA, biopolítica e governamentalidade, explicando como esses conceitos se encontram, a partir do entendimento de que a EA é um processo que molda corpos e se baseia na biopolítica, ao gerenciar maneiras de preservar a vida. Para isso, as estruturas histórico-institucionais da EA serão abordadas num contexto global e no Brasil, traçando sua relação com as macrotendências da EA e instrumentos de poder, com base em Michel Foucault, Paulo Freire e Louis Althusser. Assim, entende-se que a EA se aproxima de um horizonte da biopolítica, através de práticas governamentais para alcançar a sustentabilidade ambiental, apesar da importância dessas ações no contexto atual.
Chuva de estrelas: entre metáforas e narrativas para sentir/pensar caminhos investigativos desde nossas ancestralidades

Published: November 2021

Evocamos inquietudes acerca do fazer pesquisa e metáforas com as quais dialogamos para pensar e comunicar nossas ações investigativas polinizadas por mapas e cartografias afetivas e epistemológicas grávidas de nossas ancestralidades, territorialidades, temporalidades e histórias plurais. No movimento de pensar a investigação como aventura trans-formativa, o texto se nutre de algumas perguntas e imagens gestadas em percursos e experiências de pesquisa em constelação - sociais, teóricas, metodológicas, éticas, estéticas e políticas. Entrelaçamos indagações sobre maneiras de pesquisar que afirmam a vida, a existência singular, o minúsculo, os processos de transmutações que envolvem ressignificações de sentidos construídos… Como gesto de desmarcação ética, estética, política e decolonial, perguntamo-nos: como narrativas ancestrais de diferentes povos originários nos ajudam a plasmar outras ideias para pensar a pesquisa?
Study on Microstructure and Properties of Welded Joints with Low Strength Backing Layer for WELDOX960
Authors: Wang Zhi Ling
Published: November 2021

The welding of WELDOX960 ultra-high strength steel must consider not only the strength but also the toughness of the welding zone. In this paper, a new welding process with low strength matching backing layer is studied, that is, we choose ER50-6 wire for backing welding, use T union gm120 wire for MAG welding filling, and complete the cover welding. We prepared two groups of welding samples of ER50-6 wire backing welding and T union gm120 wire backing welding. Then we test the samples by optical metallography, tensile test, impact test and hardness test. The results show that the properties of the two kinds of backing weld can meet the requirements. The basic structure of the weld outside the backing layer of the two welding methods is similar, which are acicular ferrite and carbide. Using ER50-6 welding wire as backing, the microstructure of the weld is uniform and fine ferrite grain and a small amount of pearlite. Using T union GM120 high strength steel as backing, the microstructure of the weld is acicular ferrite and carbide. The toughness of ER50-6 is higher than that of T union GM120, and the hardness is lower than that of T union GM120.The research results have been successfully applied to the welding of large tonnage truck crane boom, and the enterprise has achieved high economic benefits.

To determine the layer required to repair a part of the aircraft, it is necessary to know the strength limit of the material and its parts. The article describes experimental measurements of manufactured composite samples that have been subjected to tensile stress. Aim of the performed tensile tests was to determine the maximum tensile stress that the composite materials are able to transmit until they are damaged. Measurement determining the maximum stress level is important to ensure the required safety of the aircraft structure on which the composite structure was repaired.

The adhesion between the carbon fibre reinforced copper matrix composite material and the coating is of particular importance for the mechanical and functional properties of the resulting system, and also for its handling and for the lifetime of the final product. To have a better understanding of the microstructure at the interface region, three different coating processes, i.e. electroplated Nickel coating, alkyd resin coating and polyolefin coating have been carried out and compared using SEM/EDX techniques. The experimental results indicate that the electroplated Nickel coating gives the best adhesion strength at the interface, suggesting this method the most promising approach and can be further investigated for electrical and electronic engineering applications in power industry.

This paper intended to measure the material's rigidity according to the orientation of the PLA specimen produced by the FDM method. To measure the change of strength and stiffness according to the direction of stacking of FDM PLA, the specimen was manufactured and tested not only in the direction of stacking but also infill using line pattern and concentric pattern. The intensity of each direction was 38.11MPa with a 0 degree tensile in the line pattern, 3.45 times higher than 11.9MPa with a 90 degree tensile, and 2.15 times higher shear strength with 28.05MPa and 13.88MPa. In concentric pattern, 0 degree tensile was 50.62MPa, 6.25 times higher than 8.46MPa, and 2.23 times higher in shear strength at 13.52MPa compared to 29.56MPa. The biggest difference in zero-degree concentric pattern tensile was the 37% difference in the 0 degree concentric pattern factor. This shows that the difference in intensity according to direction is more pronounced in concentric patterns than line patterns, and the behavior under load will be similar until the breaking point regardless of the direction.

AlSn20Cu alloy is currently one of the most widely used bearing materials, and its microstructure is the most important indicator in application. In this paper, AlSn20Cu alloy ingots were prepared by two methods: ordinary casting and semi-continuous casting, and deformation and annealing process of the two ingots were studied. Scanning electron microscope (SEM) and Image Pro Plus software were used to observe and analyze the evolution of the microstructure, and the morphological information such as the average grain size and area fraction of the Sn phase was quantitatively characterized. The effects of casting method, deformation temperature, deformation amount and annealing temperature on the morphology of Sn phase were studied in this paper. Compared with ordinary casting, the cooling rate of semi-continuous casting is higher, so the Sn phase is smaller, the casting defects are less, and the deformability of the alloy is better. The AlSn20Cu alloy prepared by ordinary casting has better deformability at about 140 °C, while the AlSn20Cu alloy prepared by semi-continuous casting can be rolled and deformed at room temperature. When the deformation is greater than 40%, after annealing at 250 °C, the average grain size of the Sn phase in the AlSn20Cu alloy prepared by semi-continuous casting is around one hundred square microns and the area fraction is more than 10%, and the Sn phase morphology is better than ordinary casting alloy under any processing conditions.

Published: November 2021

This study presents the possibility of control of nanofluidics in the bio-inspired nanosized ion channel using a field effect transistor (FET) structure. We analyzed effects from main dominant factors to control the ion flow in nanosized channel such as electro-osmosis, diffusion effect, Coulomb force between ions and pressure force. Additionally, we suggest a strategy to control the ion flow accurately at the specific position in the nanochannel by handling the viscosity, ion molecular density, pressure, gate and trans-cis voltages of FET structure.

Published: November 2021

The 3 at% Al doped ZnO thin films were deposited on p-Si substrate with a native SiO2 layer by spray pyrolysis method. Low temperature conduction behaviors were studied by analysis of impedance spectroscopy and low temperature ac conductivity. The results of impedance spectroscopy showed that the grain boundaries contributed to the resistivity of Al doped ZnO/SiO2/p-Si heterojunction. The calculated activation energy was 0.073 eV for grain boundaries. The equivalent circuit to demonstrate the electrical properties of Al doped ZnO/SiO2/p-Si heterojunction was a series connection of two parallel combination circuits of a resistor and a universal capacitor. Low temperature ac conductivity measurements indicated that the conductivity increased with temperature. Low temperature conductivity mechanism was electron conductivity, and the activation energy was 0.086 eV.

In this research we investigated the contact angle of commercial SnAgCu solder paste mixing with some carbon allotropes such as graphite, graphene quantum dots, and fullerene of varying concentrations with melting temperature, wettability, interfacial microstructure. The wettability was assessed in terms of the contact angle. The in-line digital holography was used for determining the contact angle and morphological of samples at each temperature which the samples have been heating from room temperature until the melting temperature. In the experiment, only one beam was used as the object and reference beams which recorded by a CMOS camera. The recorded image was reconstructed by the angular spectrum digital holography numerical programing. Using the reconstructed images of our results, the shape and contact angle of solder pastes can be investigated.

Published: November 2021

Gastrointestinal dysfunctions represent the most common non-motor symptoms in Parkinson’s disease (PD). Of note, changes in gut microbiota, impairments of intestinal epithelial barrier (IEB), bowel inflammation and neuroplastic rearrangements of the enteric nervous system (ENS) could be involved in the pathophysiology of the intestinal disturbances in PD. In this context, although several review articles have pooled together evidence on the alterations of enteric bacteria-neuro-immune network in PD, a revision of the literature on the specific morphological changes occurring in the intestinal mucosal barrier, the ENS and enteric muscular layers in PD, is lacking. The present review provides a complete appraisal of the available knowledge on the morphological alterations of intestinal mucosal barrier, with particular focus on IEB, ENS and enteric muscular layers in PD. In particular, our intent was to critically discuss whether, based on evidence from translational studies and pre-clinical models, morphological changes in the intestinal barrier and enteric neuromuscular compartment contribute to the pathophysiology of intestinal dysfunctions occurring in PD.
