Integrated Supplier Selection and Distribution in Perishable Food Supply Chain
Authors: Zhang Yanrong
Published: May 2023

In this study, we investigate the classical supplier selection and distribution problem in an integrated framework. The combined problem is originated from a local producing tomato sauce producer, whom we have been collaborated with since 2022. The suppler selection strategies are made based not only on each supplier’s product price and corresponding product quality, but also on the reliability and lead time of each protentional supplier. We proposed a quantitative framework with a conditional value-at-risk (CVaR) technique in the purpose of assessing the supplier performance. Then the selection and distribution decisions are simultaneously considered in a mixed integer linear programming (MILP) model, with the objective of maximizing the value added to the purchasing portfolio and distribution plans. Our experiments and computational results reveal that the combined approach is more beneficial than separated approaches. Finally, future research topics and managerial insights are provided.

Authors: Wang Ziyi , Xie Tengda
Published: May 2023

In the process of rapid human development, artificial light has gradually increased. People use artificial light more consider light to bring us benefits, but light pollution and the use of light at the same time harm human beings, even to the point of endangering human health and affecting the ecological environment. The problems caused by light pollution are waiting to be solved by us and all human beings together. In this paper, regional vulnerability (e.g., regional development level, population, biodiversity, etc.) is considered. Together with the intensity of pollution sources (e.g. road glare level, light hours, light violation level, etc.), the risk level of light pollution is determined. The risk level model of light pollution was established by calculating the weights of each index using TOPSIS entropy weighting method and hierarchical analysis method. The natural interruption point method was used to classify the risk level of light pollution into level I, level II, level III, level IV, and level v. The risk level model of light pollution was applied to four regions. We derived the risk level as level IV for urban communities, level II for protected land and suburban communities, and level II for rural communities.

Authors: Kong Yuanbo , Wu Rui
Published: May 2023

This paper reviews the academic collaboration network in COVID-19 research from January 2020 to December 2021. We first collected publication data from the Covidia (https://covidia.acemap.info) and constructed a coauthorship network. Then, we select network nodes ranking algorithms on importance from three aspects: information transmission in the network, network modularization, and network stability. Through community investigation and node ranking, we analyzed the evolving characteristics of the COVID-19 collaboration network, including the weakening of overall collaboration density, the strengthening of the network modularization trend, a more uniform distribution of researchers' influence, and the network's adaptation to major events such as international cooperation and the emergence of variant strains. Additionally, we investigated the sensitivity of different indices to international cooperation and variant strains, as well as the time delay between major COVID-19-related events and changes in network indices. This analysis provides insights into the dynamics of academic collaboration networks during the pandemic and can be used as a reference for future research in the field, including the effectiveness of different collaboration models and the potential of network analysis in identifying and predicting emerging infectious diseases.
Superposed element method for the numerical simulation of structure crack
Authors: Ding Jianxin , Yang Qingzhou
Published: May 2023

Crack is a key factor for the normal operation of structures. In this paper, a new method called Superposed Element Method (SEM) is proposed for the numerical simulation of crack analysis. Firstly, the structure containing crack is divided into two independent meshes. One is the global mesh without crack, the other is the local mesh of the crack and its vicinity. Then, the two independent meshes are coupled together, finite element method (FEM) is used for the local mesh and the complete elements outside of the coverage of the local mesh, and numerical manifold technique is applied to the incomplete elements. Finally, in order to couple the global mesh with the local mesh, the penalty stiffness is imposed on the boundaries of local mesh. The results of the numerical examples show that the pre-processing of SEM is quite simple, and the accuracy of the solution is relatively high. The method proposed is expected to be widely used for dynamic simulation of crack propagation.

A pyocele of the frontal sinus as a complication of chronic sinusitis – a case report
Authors: Król Magdalena , Dykas Kacper , Hartwich Patryk , Szaleniec Joanna
Published: May 2023

Introduction: Pyocele is a rare complication of sinusitis that is usually associated with stenosis of the ostium of the sinus caused by inflammation, trauma. Case report: A 68-year-old woman was admitted to the Otolaryngology Clinical Department of the University Hospital in Krakow, Poland because of a tumor of the right frontal bone which was painful during palpation. In anamnesis the patient reported previous laryngological surgeries associated with the treatment of chronic sinusitis. The conducted medical imaging presented the destruction of the walls of both the right and left frontal sinuses caused by pathological changes penetrating to the orbit and adhering to the dura mater. The clinical and radiological picture suggested the diagnosis of empyema of the paranasal sinus (pyocele). The patient was scheduled for bilateral endoscopic frontoethmoidectomy and the surgery ended without complications. Nowadays, the patient remains under follow-up in the outpatient otolaryngology clinic. Discussion: The main disease entity, which should be included in the differential diagnosis of pyocele is the retention cyst of the sinus. The vast majority of pyocele cases are caused by superinfection of a mucocele by bacteria (in the described case the bacterial culture of the lesion content revealed the presence of Citrobacter koseri). An efficient and sufficient method of treatment of pyocele of paranasal sinuses is their endoscopic drainage. Conclusion: In the diagnosis of pyocele, the most important are data from anamnesis, physical examination and results from computed tomography and magnetic resonance imaging. Treatment is mainly based on properly performed surgery, pharmacotherapy and consecutive rehabilitation. Endoscopic surgery is an effective procedure and its early use often prevents serious complications resulting from the expansion of the lesion.

Published: May 2023

Este trabalho apresenta os resultados da preparação de compósitos de polipropileno (PP) reforçados por fibras de açaí (FA) utilizando óleo residual de fritura (OF) como agente de acoplamento. Foram preparadas composições de PP/FA e PP/FA/OF, além de corpos de prova de PP puro para controle. Os materiais de partida e os compósitos foram caracterizados através de difração de Raios-X - DRX (para FA e PP), cromatografia em fase líquida (para OF), resistência à Flexão – RF, dureza – DZ e ângulo de Contato – AC (para PP, PP/FA e PP/FA/OF). Os resultados de DRX mostraram que as FA apresentam cristais de celulose e o PP uma estrutura semicristalina. A cromatografia revelou que o óleo exibiu uma composição majoritária de triglicerídeos. O AC indicou que as FA diminuem o caráter hidrofóbico. Já os ensaios mecânicos apontaram que, enquanto as fibras colaboram no aumento da resistência e do módulo à flexão, o OF proporciona a redução dos valores de resistência à flexão via plastificação da matriz. Por fim, embora a média da RF para PP/FA seja superior a PP/FA/OF, ambas ainda foram superiores a composição PP, sugerindo, então, a viabilidade da aplicação de FA e OF na produção de compósitos de matriz de PP.
Strong Winds and Widow Makers
Authors: Beda Steven C.
Published: May 2023

Strong Winds and Widow Makers examines what the forests have meant to the rural working-class communities spread throughout timber country, the band of forestland stretching from southern Oregon to northern British Columbia. Countering pervasive public images that often portray the Northwest’s timber workers and the rural working class as indifferent to the ecological and environmental effects of logging, this book shows that an ethic of forest stewardship has long been central to the culture and history of the people who’ve lived and worked in the Northwest woods. A desire to simultaneously protect their communities and the forests where those communities were located has shaped the identity and culture of timber workers and driven labor activism in the region, from the industrial unions of the twentieth century to the fights to protect jobs and the timber industry in the later twentieth century. Understanding this history provides new ways of thinking about people who work in nature and about the forests themselves. Listening to the voices of loggers and people from timber-working communities reminds us that forests, for all their beauty and grandeur, provide an important commodity that remains central to US and Canadian national and global economies. Listening to the voices of timber workers helps thinking about ways to balance economic uses of the forest with protecting wildlife habitat, biodiversity, and recreational space.

Amazon: its space and its inhabitants
Authors: Schuindt Elisangela , Sousa Greissi Cristina
Published: May 2023

This scientific article seeks to discuss the fallacy of the superiority of the colonizer and the inferiority of the colonized in the context of the promised land of the Amazon. Dialoguing with the theoretical field of Cultural Studies, we weave a treadmill of memorialists and/or historical nature to diagnose, through bibliographical research, the possible changes in the vision of the colonizer, from his arrival in Brazil to this historical moment, about the colonized, that is, the natives. In the attempt to obtain a position in the face of the colonialist discourse, as a reductionist vision of the Amazon region and a mistaken view about the subject and the Amazonian space, we wish to guarantee representativeness to the multiple voices of the "identities" of the subjects who inhabit the Amazon. We think of the Amazon as the between-place, a means of excellence for dialogue between the present and the past, between the native and the foreigner, between the colonizer and the colonized. A unique place that transcends the boundaries of space and time.

Published: May 2023

This research aimed to propose molecular modifications and compare the characteristics of three barbiturate drugs and their analogues developed in silico through procedures and computational techniques using free programs. Barbiturates were the class chosen for this study, the selected drugs were: Phenobarbital, Pentobarbital and Amobarbital, being modified through simulations in silico. Three analogues were proposed, being analyzed and compared with the prototypes, using the free programs, Marvinsketch, where it was possible to evaluate parameters such as: Log P, hydrogen donors/acceptors and Van Der Walls Surface. In PreADMET, parameters such as BHE, HIA, Caco-2, MDCK, CYP-3A4, Ames Test, Carcinogenicity (Rats) and hERG Risk were obtained. Through the Osiris Property Explorer, the following parameters were evaluated: Mutagenicity, tumorigenicity, irritability, reproductive effect, solubility, molecular weight, polarity, druglikeness and Drug-Score. With the results obtained in PreADMET referring to BHE, the analogues BBT-F and BBT-A obtained better results, while the BBT-P had a worsening in the result. In relation to HIA, the values proved to be satisfactory, exhibiting good intestinal absorption. As for toxicity, the Ames test was verified, where all molecules were mutagenic. With the results obtained in Osiris, all the prototype drugs proved to be mutagenic, while in the analogues, only BBT-P showed mutagenicity. As for tumorigenicity, the prototype drugs remained at medium to high risk, while analogue drugs all showed non-tumorigenic results. Therefore, it is concluded that it was possible to make a preliminary, fast and low-cost analysis, helping in the research of new drugs through computational tools.
In the Pé(rré) accent of Pernambucan
Authors: Souza Fernando Antônio Ferreira de
Published: May 2023

The perspective that emerges from the mismatch between what is read and what is heard encompasses infinite directions. The complexity of these perceptual and expressive mismatches approaches the concept of accent under the symbolic effect of the idea that as a dimension of the characteristics of the expressive speech of individuals, the accent allows speculative associations, and consequently endowed with limited rationality. This article emerges from the search to identify the thoughts of the bearer of a musical accent, an individual who is a member of a specific group outside the listener's universe and, therefore, subject to judgments based on speculation. The accent arbitrarily starts to indicate competences associated with socio-economic status, ethnicity and geopolitical origin, as well as educational levels. This article emerges from the experience of participant observation with emic musicians from musical traditions of the oral culture of Pernambuco from 2003 to 2019, when the perré element emerged as a marker of a common language which links with the local accent.

hiperglicemia gerada pelo diabetes mellitus promove alterações fisiológicas em todo o organismo, sendo recorrente o aparecimento de distúrbios gastrintestinais nos portadores desta doença, devido ao dano ao plexo mioentérico. Além do diabetes, sabe-se que há uma relação entre o uso do tabaco e dislipidemia no sistema digestório, porém, ainda há uma lacuna no conhecimento sobre possíveis alterações nos neurônios entéricos. Algumas plantas medicinais são apontadas como terapias complementares no tratamento de doenças gastrointestinais, dentre elas, a Baccharis trimera, que possui em sua composição antioxidantes, que podem exercer efeito neuroprotetor nos neurônios do plexo mioentérico. O objetivo do presente estudo foi avaliar o possível efeito protetor da B. trimera, popularmente conhecida como carqueja, sobre os neurônios mioentéricos, perfil lipídico e glicêmico de ratos expostos ao modelo experimental com a indução do diabetes mellitus, dislipidemia e o tabagismo. Quanto aos neurônios mioentéricos a carqueja não apresentou efeitos protetores com redução significativa na quantificação da população total, e a manutenção da subpopulação nitrérgica em todos os grupos, nos permite sugerir que estes neurônios são mais resistentes aos efeitos deletérios do diabetes, tabagismo e dieta hipercolesterolêmica.

Recursos alternativos à medicina estão em ascensão quando da procura por alternativas que auxiliem na superação das problemáticas relacionadas ao estresse, ansiedade, problemas comportamentais e psicológicos, levando o indivíduo a sensação do bem-estar e atuando tais sintomatologias. A Ayahuasca é uma bebida tradicionalmente usada em cerimônias indígenas da região amazônica, e tem sido explorada em contextos terapêuticos para promover bem-estar e auxiliar no tratamento de problemas de saúde mental. Objetiva-se neste estudo reunir literaturas acerca da utilização da Ayahuasca por pessoas que buscam uma sensação de bem-estar e desejam melhorar problemas relacionados à saúde mental. Para isso, utilizou-se de uma revisão narrativa de literatura entre os meses de outubro de 2023 a abril de 2023, sendo que os bancos de dados eletrônicos Scopus, PubMed e Web of Science foram utilizados para pesquisar os artigos relevantes. Como resultado, foram identificados 53 artigos, sendo que apenas 35 deles foram selecionados para inclusão no presente estudo. A Ayahuasca, uma bebida enteógena com propriedades psicoativas e que tem sido utilizada por povos indígenas em rituais há muitos anos. Estudos recentes exploraram seu potencial terapêutico no tratamento de transtornos psiquiátricos, como a depressão, obtendo resultados promissores. Perspectivas futuras para melhorar a compreensão desse tema incluem a realização de estudos interdisciplinares que abordem a Ayahuasca a partir de diversas perspectivas, como farmacêutica, neurológica, psicológica, antropológica e religiosa. Isso permitiria uma compreensão mais ampla e aprofundada dos efeitos da bebida em diferentes níveis, assim como sua relevância cultural, histórica e terapêutica.

Essential and vegetable oils are rich in bioactives, which can act on the skin through their therapeutic properties. However, they are often sensitive to oxidation and degradation, making it necessary to use resources for their protection. The nanoencapsulation of these oils allows bioactives to have their properties protected and optimized through the sustained release of actives, reduced toxicity, and even greater penetration capacity and better distribution in the skin layers, enhancing their effects. Polymeric nanoparticles, particularly, have shown important results for delivery of bioactives to the skin, and can be produced from natural or synthetic polymers, which present biocompatibility and biodegradability. The main methods for obtaining these nanostructured materials are nanoprecipitation, coacervation and ionic gelation, and these methods are the scope of this literature review.
Design and Simulation of a Model Reference Adaptive Control System Using the Recursive Least Squares Method with Forgetting Factor for Gain Adjustment

Published: May 2023

This article coupled the Recursive Least Squares Method with Forgetting Factor (RLS-FF) to a Model Reference Adaptive Control (MRAC) system and described an analysis for a second-order plant with variable and unknown parameters. In the industrial context, manufacturing processes demand to be controlled, however there are variant and even unknown parameters, a consequence of non-modeled dynamics. Thus, an algorithm capable of estimating the controller gains from the RLS-FF was proposed. Next, the MRAC simulation was carried out and the numerical results were obtained, regarding the target parameters of the control system. Through mathematical description and computational simulation, the results were promising, such as the convergence of controller gains. Therefore, this article aims to contribute with students and professionals in the field of Control and Automation, who are looking for models of adaptive control systems, in order to check, compare and implement new embedded technologies.
Avaliação mecânica de concretos com agregado graúdo proveniente de resíduos de construção civil otimizados pela técnica de dopagem

O potencial produtivo do setor da construção civil traz como consequência a elevada geração de resíduos, que muitas vezes não possuem um descarte correto. Uma alternativa para o problema é o emprego destes Resíduos de Construção Civil (RCC) em concretos. Alguns estudos mostram resultados favoráveis a esta aplicação. Porém, há de se atentar a algumas limitações do material, como baixa resistência mecânica. Uma possível maneira de melhorar suas características é a aplicação da técnica de dopagem, que consiste em impregnar o agregado com uma calda de alto desempenho, contendo cimento, sílica ativa e aditivo superplastificante, de forma a alterar sua estrutura superficial. Este estudo teve como objetivo avaliar as características mecânicas de concretos produzidos com agregados graúdos provenientes de RCC otimizados pela técnica de dopagem. A análise da eficiência se deu pela comparação das misturas com agregado dopado e misturas controle (elaboradas com agregados não dopados), mediante ensaios de compressão axial, tração por compressão diametral, absorção de água e determinação do módulo de elasticidade. Os resultados mostram que a técnica de dopagem no agregado não trouxe benefícios aos concretos.
