FORMATION OF THE ORGANIZATION OF THE RIGA PILOT SHOP
Authors: Kirov A. A.
Published: April 2022

The article presents the material collected by the author related to the study of the legal organization of the Riga Pilot Shop from the XIII to the second half of the XIX centuries. It is indicated that the pilot shop that served the port of Riga was formed in the XVII century, shortly after the establishment of the post of Water Captain and the appearance of customs on the right bank of the Daugava River, opposite the Daugavgrivskaya fortress. According to the regulations, Bolderaya was defined as the place of residence of the pilots, who could change it only in exceptional cases. After the conclusion of the Peace of Nishtat (1721) and the entry of Riga into the Russian Empire, the activities of pilots of its port were regulated by such normative acts as the «Charter on Riga Commerce» of 1765, the decree of March 4, 1840 «On increasing the pilotage Fee in the Port of Riga», the charter of Riga pilots of 1854, which was valid until 1904, i.e. before the adoption of the new charter. The Charter of 1854 was much more detailed than previously issued regulations and charters and played a significant role in the development of rationing of pilots ‘ activities throughout the Russian Empire.

Published: April 2022

Solar energy is a combination of light and heat produced by the sun, where this energy is utilized by humans through solar collector technology consisting of PV modules to be converted into electrical energy. The development of PV module technology is carried out to improve its performance, where one of these technologies uses a reflecting mirror to increase the amount of sun radiation captured by the surface of the PV module. This research method uses performance analysis of the utilization of reflector mirrors added to the PV module system by using two different cases, among others are the use of two and four mirrors along the sides of the PV module. The results showed that the application of four reflective glass can direct the sun's radiation to the surface of the PV module with the amount of radiation intention doubled. This result is a kind of technology that gives us a good result to utilize it in building the solar power plant.

Published: April 2022

Optimal cost management in terms of logistics systems and the utilization of the science of "Logistics", as it has been shaped with modern technology, lead the exported cost elements to the most important factor in decision making. One of the tools that contribute to the decision-making process is the cost of life cycle of weapon systems. This tool can be extremely useful as it contains information, such as codified materials, and spare parts according to NATO Codification System, which assists and facilitates the work of the logisticians in supporting army’s weapon systems. Furthermore, the degree of dependence of a material or a spare part (which make up a weapon system) by its OEM (Original Equipment Manufacturer) and the significant role of it, could consist of an extra key in changing all the life cycle support of the weapon system and the decisions related to it.

This article presents the results of an analysis of how passive and active scaffolding, as types of structured student learning support, can be provided for refugees and migrants in Language MOOCs (LMOOCs). It focuses on the nature of such scaffolding and what effect it has on learning. After an analysis of the theoretical aspects of supporting refugees and migrants in this type of course a case study is presented. This study focuses on the inclusion of scaffolding in the design, development and running of two Spanish LMOOCs for immediate needs, created within the MOONLITE[1] project in collaboration with support groups for displaced people. The results of the study support the use of scaffolding as a mechanism that improves the course completion rates (increasing from the usual figure of around 10% to 31% and 30% in the respective courses), language learning, and the overall satisfaction and motivation of the students.

We investigate the assembly history of massive disk galaxies and describe how they shape their morphology through cosmic time. Using SHARDS and HST data, we modeled the surface brightness distribution of 91 massive galaxies at redshift 0.14 < z ≤ 1 in the wavelength range 0.5–1.6 μm, deriving the uncontaminated spectral energy distributions of their bulges and disks separately. This spectrophotometric decomposition allows us to compare the stellar population properties of each component in individual galaxies. We find that the majority of massive galaxies (∼85%) build inside-out, growing their extended stellar disk around the central spheroid. Some bulges and disks could start forming at similar epochs, but these bulges grow more rapidly than their disks, assembling 80% of their mass in ∼0.7 and ∼3.5 Gyr, respectively. Moreover, we infer that both older bulges and older disks are more massive and compact than younger stellar structures. In particular, we find that bulges display a bimodal distribution of mass-weighted ages; i.e., they form in two waves. In contrast, our analysis of the disk components indicates that they form at z ∼ 1 for both first- and second-wave bulges. This translates to first-wave bulges taking longer to acquire a stellar disk (5.2 Gyr) compared to second-wave, less compact spheroids (0.7 Gyr). We do not find distinct properties (e.g., mass, star formation timescale, and mass surface density) for the disks in both types of galaxies. We conclude that the bulge mass and compactness mainly regulate the timing of the stellar disk growth, driving the morphological evolution of massive disk galaxies.
The Universal Specific Merger Rate of Dark Matter Halos

Published: April 2022

We employ a set of high resolution N-body simulations to study the merger rate of dark matter halos. We define a specific merger rate by normalizing the average number of mergers per halo with the logarithmic mass growth change of the hosts at the time of accretion. Based on the simulation results, we find that this specific merger rate,

−1) and merger ratios (ξ ≥ 1e − 2). We further test with simulations of different Ω

and σ
8, and get the same specific merger rate. The universality of the specific merger rate shows that halos in the universe are built up self-similarly, with a universal composition in the mass contributions and an absolute merger rate that grows in proportion to the halo mass growth. As a result, the absolute merger rate relates with redshift and cosmology only through the halo mass variable, whose evolution can be readily obtained from the universal mass accretion history (MAH) model of Zhao et al. Last, we show that this universal specific merger rate immediately predicts an universal unevolved subhalo mass function that is independent on the redshift, MAH or the final halo mass, and vice versa.
Metal Mixing in Minihalos: The Descendants of Pair-instability Supernovae

Published: April 2022

The lack of observations of abundance patterns originating in pair-instability supernovae has been a long-standing problem in relation to the first stars. This class of supernovae is expected to have an abundance pattern with a strong odd–even effect, making it substantially different from present-day supernovae. In this study, we use a cosmological radiation hydrodynamics simulation to model such supernovae and the subsequent formation of the second generation of stars. We incorporate streaming velocities for the first time. There are 14 star-forming minihalos in our 1 cMpc h
−1 box, leading to 14 supernovae occurring before redshift z = 19.5, where we start reducing the complexity of the simulation. Following the explosions, extremely metal-poor stars form in 10 halos via internal and external enrichment, which makes it the most common outcome. Only one halo does not recollapse during the simulations. This result is at variance with the current (lack of) observations of metal-poor stars with pair-instability supernova abundance patterns, suggesting that these very massive stars might be rare even in the early universe. The results from this simulation also give us insights into what drives different modes of recollapse and what determines the mixing behavior of metals after very energetic supernovae.
Metallicity, Ionization Parameter, and Pressure Variations of H ii Regions in the TYPHOON Spiral Galaxies: NGC 1566, NGC 2835, NGC 3521, NGC 5068, NGC 5236, and NGC 7793

We present a spatially resolved H ii region study of the gas-phase metallicity, ionization parameter, and interstellar medium (ISM) pressure maps of six local star-forming and face-on spiral galaxies from the TYPHOON program. Self-consistent metallicity, ionization parameter, and pressure maps are calculated simultaneously through an iterative process to provide useful measures of the local chemical abundance and its relation to localized ISM properties. We constrain the presence of azimuthal variations in metallicity by measuring the residual metallicity offset Δ(O/H) after subtracting the linear fits to the radial metallicity profiles. We, however, find weak evidence of azimuthal variations in most of the galaxies, with small (mean 0.03 dex) scatter. The galaxies instead reveal that H ii regions with enhanced and reduced abundances are found distributed throughout the disk. While the spiral pattern plays a role in organizing the ISM, it alone does not establish the relatively uniform azimuthal variations we observe. Differences in the metal abundances are more likely driven by the strong correlations with the local physical conditions. We find a strong and positive correlation between the ionization parameter and the local abundances as measured by the relative metallicity offset Δ(O/H), indicating a tight relationship between local physical conditions and their localized enrichment of the ISM. Additionally, we demonstrate the impact of unresolved observations on the measured ISM properties by rebinning the data cubes to simulate low-resolution (1 kpc) observations, typical of large IFU surveys. We find that the ionization parameter and ISM pressure diagnostics are impacted by the loss of resolution such that their measured values are larger relative to the measured values on sub-H ii region scales.

An Evaluation of Electrostatic Lofting and Subsequent Particle Motion on Bennu
Authors: Hartzell Christine , Zimmerman Michael , Hergenrother Carl
Published: April 2022

Electrostatic lofting is the detachment of particles from a surface that occurs if the electrostatic force on the particles is greater than the forces binding the particles to the surface. Electrostatic lofting has been hypothesized to occur on the Moon and observed in the laboratory environment. Because gravity is much weaker on asteroids than on the Moon, the hypothesis of electrostatic lofting has naturally been extended to these smaller airless bodies. We evaluate the feasibility of electrostatic lofting on Bennu using two formulations of the patched charge model. We find that submillimeter particles can be lofted from Bennu’s dayside and, depending on their initial conditions, will reimpact or escape. The size and speed of the predicted electrostatically lofted particles are compared to those of the particle ejection events recently observed on Bennu. We find that dayside electrostatic lofting is not consistent with the size and speed of particles in the largest ejection events observed by the OSIRIS-REx mission. However, the escape of submillimeter particles has implications for the particle size distribution on Bennu’s surface. Additionally, we model particle charging on Bennu’s nightside due to secondary electron emission and find the resulting electrostatic force to be too weak to produce electrostatic lofting on the nightside.
Un regard anthropologique sur les voies et les limites de l’innovation dans les marchés traditionnels : le cas du thé vert au Maroc
Authors: El Hassouni Soumaya
Published: April 2022

Cette recherche vise à explorer les rituels qui accompagnent la consommation d’une boisson traditionnelle le but étant d’identifier les pistes et les résistances à l’innovation. L’étude porte sur une boisson à fort contenu culturel et dont l’acte de consommation s’accompagne de plusieurs rituels traditionnels : le thé à la menthe au Maroc. La recherche a été menée suivant une démarche interprétativiste des données recueillies auprès de deux groupes de consommateurs. L’analyse de contenu appuyée par le logiciel NVIVO a permis l’émergence de plusieurs représentations : emprunté à l’anthropologie alimentaire, le concept de commensalité est éclairant en matière de motivation à l’observance des rituels et, par ricochet, de barrière à l’innovation. Le plaisir gustatif et, dans une moindre mesure, l’identité culturelle sont également prégnants. Les freins à une consommation traditionnalisée sont la résultante d’une attitude plus rationnelle et permettent d’envisager de possibles pistes à l’innovation : ils s’articulent autour du risque sanitaire, du défaut de praticité ainsi que du blasement des goûts.
Impact de la reconnaissance au travail sur le comportement d’innovation : effet modérateur de la confiance organisationnelle - cas des ingénieurs dans les entreprises privées au Maroc
Authors: Chaibi Yassine , Siragi Fatima Ezzahra , Berbou Houcine
Published: April 2022

Dans le contexte actuel, la créativité et l’innovation jouent un rôle important pour répondre à des problèmes complexes et croissants nécessitant des approches plus participatives pour favoriser les initiatives pouvant créer de la valeur ajoutée aux organisations. Malgré la cohérence des études empiriques en terme de conséquences positives du comportement d’innovation, les connaissances sur les pratiques de gestion des ressources humaines et la manière dont elles peuvent influencer ce type de comportement demeurent fragmentées et incohérentes. À partir du corpus théorique et empirique relevé, le présent papier vise à apporter un éclairage sur le champ de l’innovation au niveau individuel et enrichir le contenu de l’échange social, en testant un modèle mettant à jour le rôle modérateur de la confiance organisationnelle dans l’explication des effets de la reconnaissance sur le comportement d’innovation. En adoptant un mode de raisonnement déductif, nous avons mené une étude quantitative auprès de 181 ingénieurs employés dans des entreprises privées au Maroc. Les résultats soulignent le rôle central de la reconnaissance de la part des supérieurs hiérarchiques dans le processus d’innovation et montrent également que parmi les deux dimensions de la confiance organisationnelle, seule la crédibilité de l’entreprise -dimension rationnelle-permet d’intensifier l’effet positif de la reconnaissance de la part du supérieur sur le comportement d’innovation. Ainsi, ce travail comble un écart persistant au niveau de la littérature et met en évidence une thématique d’actualité en rapport avec les pratiques RH qui permettraient de stimuler le comportement d’innovation qui est essentiel aussi dans les situations de crise.

Survey on the factors and social perspectives to participate in home composting schemes in Palestine: Anabta case study
Authors: Sayara Tahseen , Hanoun Ruba , Hamdan Yamen
Published: April 2022

In this study, a survey was conducted to determine the public opinion regarding the acceptance of using home composters as an alternative approach for household organic waste management. This approach is introduced as a method to replace the landfilling of organic municipal solid waste, which is the main solid waste management currently employed in Palestine, considering Anabta town as a case study. The results showed that people in the target area are welcoming of the home composting idea, and about 99% of participants are interested in owning home composters at their properties, which is regarded as a good reference for implementing the proposed home composting scheme in this area. The results showed that people are interested in the new proposed scheme for organic household waste despite their minimal knowledge and understanding about the composting process's importance and effects. The survey tested the people's expectations and thoughts about the home composting concept and found that the main motives for home composting were reducing the cost of house gardening and using the produced compost in soil nutrition, besides being part of environmental sustainability. On the other side, obstacles were due to people's inexperience of the home composting method, as almost half of participants were expecting an exhausting, long process to produce compost, with the related bad smell and insects during composting progression. Hence, the study found that it is important to spread awareness about the right procedures to apply home composting among participants, in line with environmental awareness campaigns through social media, and provide personalized follow-up with participants.
Kant on Decomposing Synthesis and the Intuition of Infinite Space
Authors: Rosefeldt Tobias
Published: April 2022

In the Transcendental Aesthetic of the Critique of Pure Reason, Immanuel Kant famously claims that we have an a priori intuition of space as an ‘infinite given magnitude’ (A25/B39f.). Later on, in the Transcendental Analytic, he seems to add that the intuition of space presupposes a synthetic activity of the transcendental imagination. Several authors have recently pointed out that these two claims taken together give rise to two problems. First, it is unclear how the transcendental imagination of a finite mind could ever result in the intuition of an entity that is infinitely large. Second, Kant claims that our intuition of space has a ‘whole-prior-to-its-parts’ structure, such that its parts are given only as limitations of the whole, while synthesis is compositional and has a ‘parts-prior-to-their-whole’ structure, because it consists in first running through and then taking together the parts of a sensible manifold. I will solve these two problems by showing that Kant thought that synthesis does not always have a compositional structure but that there is also a form of ‘decomposing’ synthesis, which has a whole-prior-to-its-parts structure. Building on similarities between Kant, Edmund Husserl and G. W. F. Hegel, I will argue that infinite space is given to us in intuition by precisely such an activity of decomposition, one that allows us to differentiate between finite spatial objects and the unlimited phenomenal horizon in which they appear.
Telemedicine Services
Authors: Tafuro Alessandra , Dammacco Giuseppe
Published: April 2022

Telemedicine services, with the collection and sharing of patient clinical data, have gone from an emergency response during the pandemic to an essential structural investment for the Italian health system. Telemedicine is a part of the main digital transformation process in healthcare and is establishing itself as a key technological tool to increase the efficiency and effectiveness of the system. Indeed, it can make the difference in each phase of healthcare, from prevention to access to care, up to the real patient care, helping to shift the center of gravity of the Italian healthcare system moving from the centralized care in the hospitals to home healthcare. Through a literature review, an overview of the telemedicine in the Italian context is proposed, discussing the factors that facilitate its development, the main barriers to its implementation, and the future prospects of these digital tools that are useful to support the National Healthcare System.

Published: April 2022

Telemedicine is a new branch of medicine exploiting the new communication devices to expand medical services and consultation beyond physical limits. This new significant chapter in medicine will interest every medical area, taking advantage of digital devices that are becoming more complex, reducing the need for the patient's physical presence only to perform analysis or interventions. Teledermatology is a new expanding area in telemedicine, consisting of the ability to resolve skin-related health problems without the physical presence of the patients. Skin diseases represent a significant source of morbidity and a minor source of mortality worldwide. In this chapter, the authors analyze how telemedicine and teledermatology developed, their current use in medicine, and current studies and reviews already present in literature. Also, future possible prospects and developments of these techniques will be analyzed.

Published: April 2022

The purpose of this study is to describe intensive care nurses' perceptions and experiences of shift working and reveal how to cope with its effects. Data were collected through an individual semi-structured interview guide and transcribed verbatim by using a qualitative descriptive design. Interviews were done with 11 Turkish intensive care unit nurses. As a result of the analyses, four main themes were obtained: 1) the effects of shift working on nurses' lifestyle, 2) the effects of shift-working on nurses' working life, 3) the effects of shift working on nurses' patient care practices, and 4) the strategies used by nurses to cope with the effects of shift-working. The positive and negative consequences of the multifaceted effects of shift-working perceived by nurses should be taken into consideration, and individuals or a group of nurses who have been searching for strategies to cope with and overcome these effects should be supported.

Published: April 2022

This chapter aims to investigate the efficiency of nations in their struggle against the COVID-19 analysing data from June and December 2020 with a novel three-stage methodology. In the first stage, 107 nations were clustered into highly competitive, competitive, and non-competitive countries using their Global Competitiveness Index scores (World Economic Forum) to evaluate comparable countries in the second stage with the Data Envelopment Analysis. In the third stage, the relationship between countries' efficiency and performance in 66 variables published in the United Nations Human Development Report was investigated along with the long-debated aspect of a nation's political governance regime using Tobit regression. The worst performing highly competitive nations were USA and UK, competitive nations were Chile and Peru, and non-competitive nations were Brazil and Mozambique. Air pollution, international inbound tourists, urban population significantly reduced while domestic credit and gross national income per capita significantly increased efficiency, but the political regime did not affect it.
Who Contributes to the Sunk Costs of Motor Vehicle Carbon Emissions and Human Capital?
Authors: Zhang Wei , Chen Hong , Wang Sufang
Published: April 2022

Most carbon emission reduction studies in transportation focus on the natural use of motor vehicles. However, little attention has been paid to fatal driving violations that lead to the sunk costs of human resources investment and motor vehicle carbon emissions in the manufacturing process of motor vehicles. This article aimed to determine if a driver would be seriously harmful to human capital investment and carbon emissions reduction. 1893 drivers in China were formally surveyed by questionnaire to find out the statistical characteristics. Results indicated that different drivers show significant differences in different driving violations dimensions. Specific drivers showing horrible driving violation (HDV) and dangerous driving violation (DDV) mainly endanger personal security and environmental damage. The identification of the focused drivers would contribute to formulate more refined management policies in carbon emission reduction, improve natural resource utilization, raise human capital benefit, and promote social sustainable development.

A urbanização vem se expandindo rapidamente e muitas vezes de forma irregular, adentrando cada vez mais áreas antes rurais. Dessa maneira, o uso e ocupação do solo modifica-se, aumentando o índice de impermeabilização do solo, afetando e degradando a bacia hidrográfica local. Para tanto, este trabalho busca analisar o desenvolvimento e evolução da urbanização na bacia do Ribeirão Maringá, afluente do Rio Pirapó, bem como traçar um índice de ocupação para os próximos anos. Com o uso de softwares de tecnologia SIG e imagens dos satélites Landsat 5, 7 e 8, além de imagens da missão SRTM, foi estudada a bacia hidrográfica a fim de delimitá-la e determinar a porcentagem de ocupação urbana em vários anos entre 1984 e 2014. A partir dos dados obtidos, foi possível projetar a porcentagem de urbanização da bacia para os anos futuros. Constatou-se que, com o uso da tecnologia SIG, a visualização da situação da bacia torna-se mais fácil e assim contribui para o entendimento dos problemas de impermeabilização, uso e ocupação do solo.

Inúmeros países incorporam a simulação computacional em suas normas e regulamentos voltados ao desempenho térmico de edifícios. O modelo virtual criado nesses programas é uma representação de um edifício real, sujeito a simplificações e limitações específicas. O objetivo deste trabalho é avaliar diferentes alternativas de modelagem de habitações de interesse social no programa de simulação de desempenho térmico EnergyPlus. Para tal, foram simuladas duas habitações no clima de São Carlos, SP, Brasil, considerando variadas possibilidades para os seguintes aspectos: temperatura do solo, caixilhos, venezianas, beirais e dimensões das superfícies. Os dados foram analisados através do índice de conforto adaptativo prescrito pela norma internacional ASHRAE 55 (soma anual dos graus-hora de frio e de calor) e do método de avaliação do desempenho térmico proposto pela norma brasileira ABNT NBR 15575 (dias típicos de verão e inverno). Os resultados indicaram o impacto significativo da temperatura do solo, e em menor proporção, das venezianas e dos beirais. Dessa forma, é possível fornecer subsídios quantitativos para a tomada de decisões conscientes durante o processo de simulação.

A utilização de fibras vegetais como material de reforço em argamassas de cimento Portland tem despertado grande interesse de empresas e pesquisadores de diversos ramos de atuação em resposta a preservação ambiental. Entre a grande variedade de fibras vegetais existentes, foi escolhida para ser caracterizada neste trabalho a fibra de buriti. A escolha dessa fibra considerou o desenvolvimento econômico regional e a pequena quantidade de estudos com essa fibra. Foram avaliadas a influencia da incorporação da fibra no índice de vazios, na absorção de água e na massa específica dessas argamassas. Foram adicionados 0 %-p, 7 %-p e 14 %-p de fibras de buriti em substituição a areia na confecção das argamassas. As misturas foram elaboradas com o cimento Portland CPII-E 32, formulados traços em volume de 1: 2: 9 (cimento: cal: agregados), com adições de 500 ml e de 600 ml de água. A cura dos corpos de prova foi realizada em 28 dias. Pôde-se observar o aumento do índice de vazios com o aumento da porcentagem de fibra para os dois teores de adições de água na formulação. O aumento do índice de vazios com a redução do fator água-cimento (a/c), provavelmente devido à absorção de água pela fibra foi observado. O aumento da absorção de água e a diminuição da massa específica com o aumento da porcentagem de fibras também foram evidenciados.

A formação de engenheiros no Brasil, em termos tanto qualitativos quanto quantitativos, passou a ser um parâmetro determinante no processo de desenvolvimento tecnológico do país. Entre os problemas que afetam o índice de formação dos engenheiros estão no processo de evasão e o elevado tempo de integralização do currículo. Estes problemas têm várias vertentes, como diminuição do ritmo de desenvolvimento tecnológico do país, aumento dos gastos públicos e privados e as questões sociais advindas do processo. Diante desta realidade, este artigo tem por objetivo levantar e apresentar dados sobre evasão acadêmica e tempo de integralização do curso de Engenharia de Produção da Universidade Estadual de Maringá (UEM) no período de 2000 a 2013. Para a realização do estudo foram utilizadas informações do banco de dados da Diretoria de Assuntos Acadêmicos (DAA). Ao seu final foi possível observar que somente cerca de 56% dos alunos que concluem o curso o fazem no tempo mínimo regular (cinco anos), e que o índice de evasão, quando calculado por turma, chega, em média, a 32,9% dos alunos iniciantes, e quando mensurado por ano, o índice médio de alunos desistentes atinge 11,4%.

O presente trabalho teve como objetivo avaliar a desidratação osmótica de tomates utilizando solução osmótica de sacarose/NaCl+KCl. Buscando tal propósito, a cinética de desidratação foi obtida e avaliou-se o efeito das variáveis de processo, temperatura, agitação e proporção sacarose/sal, nas respostas teor de umidade, perda de água e ganho de sólidos. A partir dos resultados cinéticos obtidos constatou-se que a substituição parcial do NaCl não apresenta influência significativa (p>0,05) no processo de desidratação. A temperatura e proporção sacarose/sal foram às variáveis com maior influência na umidade e perda de água. A agitação apresentou efeito significativo apenas no ganho de sólidos do material.

A reforma a vapor do etanol e glicerol é uma rota interessante para a produção de H2, para isso se torna necessário a síntese de catalisadores com boa atividade e viáveis economicamente. Neste cenário, catalisadores de níquel suportados em alumina (Al2O3) vêm sendo muito estudados no processo de reforma. Neste trabalho, foi sintetizado um catalisador com 30% de níquel suportado em alumina peletizada (30%Ni/Al2O3), pelo método de impregnação úmida, e caracterizado pelas técnicas de absorção atômica em chama (teor metálico), fisissorção de N2, RTP, DRX e DTP-NH3. Para os testes catalíticos, foi utilizado um reator tubular de aço inox de leito fixo, temperaturas de 450, 550 e 650 °C, velocidade espacial (WHSV) de 100 L h-1 gcat-1 e etanol ou glicerol. Nas reações o aumento da temperatura levou a uma maior produção de H2, sendo que os maiores percentuais observados foram em 650 °C. Na ausência do catalisador ou em baixas temperaturas, foi observada uma maior produção de compostos indesejáveis como metano, eteno e etano.

One of the most important factors influencing the quality of the weld created by the micro friction stir welding is the amount of heat generated during the welding operation. Due to the lack of proper mixing of materials at low temperatures, joints' quality decreases due to the formation of cold welds. Also, overheating takes the process out of solid-state welding, which prevents good joints. Finite element analysis of friction stir welding leads to a better understanding of the effect of different parameters on the process. With the results extracted from such analysis, some of the output can be predicted, such as heat distribution. In the present study, in order to perform finite element analysis of the micro friction stir welding of Al 1050 to pure copper, the coupled Eulerian-Lagrangian method in Abaqus software has been used. The results of finite element analysis showed that the heat distribution on the copper side is wider due to the higher heat transfer coefficient of copper than aluminum. The maximum temperature in the analysis was recorded in the weld line, which was 392°C. The heat generated during the welding process was measured at different points relative to the joint line, and appropriate matching was observed with a comparison of experiments and simulation results.

Published: April 2022

Natural fibers have been extensively studied as a reinforcement filler in obtaining composites, replacing partially synthetic fibers. The vast majority of these materials originate from agro-industrial waste with a high content of lignin and cellulose making it a very interesting material with low cost and good mechanical properties. The purpose of the study was to obtain a composite based on alkyl ketene dimer resin, for the manufacture of sustainable packaging, made of paper by adding a 10% (w/w) con-tent of green coconut fiber and sugarcane bagasse fiber, and evaluated the impact of the filler on the mechanical behavior of the systems. The studied material was characterized from mechanical tests, such as Ring Crush Test (RCT) and Concora Medium Test (CMT) evaluating the maximum resistance supported by centimeter in the pre-pared composites, by the specimens. Through the RCT tests, with 10% w/w fibers, it was possible to verify that the fiber from sugarcane bagasse reached an increase of about 1% in the reinforcement effect compared to pure paper, and a difference of up to 2% in strength mechanics in relation to coir fiber, and CMT tests shows the reinforcement effect of the presence of sugarcane bagasse fiber, with an increase of about 3% compared to pure paper, and with a mechanical strength higher by 1% compared to coconut fiber. Therefore, the study was funneled with sugar cane fiber, varying the content by 20 and 30 % (w/w), evaluating the impact on the dispersion of this filler in the polymeric matrix and, consequently, the mechanical response of the composite with these compositions. The conclusion of the study was that the system prepared with 20% (w/w) was the one that achieved the greatest optimization of the mechanical properties, evaluated by the tests. This type of material can be applied to obtain cardboard boxes with resistance to high loads, due to the achievement of good mechanical properties.
