Authors: Silva Roberta Estevão da , Meira Alexsandra Rocha , Araújo Nelma Mirian Chagas de
Published: September 2023

Atualmente o setor da construção civil enfrenta graves problemas referentes à geração dos resíduos nos seus canteiros de obras, principalmente em função do acelerado processo de verticalização das metrópoles. Além disso, os resíduos, por muitas vezes, são dispostos em locais inadequados. Em consequência dessa conjuntura, a partir de 2002, a Resolução n.° 307 do Conselho Nacional de Meio Ambiente (CONAMA) entrou em vigor, estabelecendo diretrizes e normas para o tratamento e, sobretudo, para a não geração dos resíduos. Iniciou-se, então, um processo gradativo de interesse pela gestão dos resíduos por parte das construtoras. Este artigo apresenta o resultado de pesquisa realizada na cidade de João Pessoa com o objetivo de quantificar o volume de resíduos gerados por uma obra e os custos de retirada destes, bem como quantificar o volume de resíduos dispostos na Usina de Beneficiamento de Resíduos de Construção e Demolição (USIBEN) e de resíduos reciclados. A partir dos resultados obtidos, foram elaborados diagnósticos da obra pesquisada e da Usina, os quais podem ser utilizados como ponto de partida para pesquisas futuras ou como ferramentas gerenciais para a tomada de decisão, tanto por empresas construtoras quanto por usinas de reciclagem de RCCs (Resíduos da Construção Civil).

Authors: Leite Thiago Rodrigues Alexandria , Santos Carlos Antônio Cabral dos
Published: September 2023

Este trabalho tem por objetivo apresentar os resultados das análises energética, exergética e exergoeconômica de um protótipo de ar-condicionado utilizando módulos termoelétricos. Dois principais ensaios foram feitos: o primeiro variando a temperatura da água e o segundo variando a corrente de entrada do sistema. Pela análise energética, foram calculados o coeficiente de desempenho do sistema (COP) e a capacidade de refrigeração (Qc). Através da análise exergética, foram calculadas a destruição de exergia, a exergia de refrigeração, e a eficiência exergética de refrigeração. Por fim, pela análise exergoeconômica, que utilizou o método SPECO, foi calculado o custo por unidade de refrigeração (cq). Os resultados indicaram, através da análise energética, que o COP é maximizado para correntes de entradas menores e para temperaturas da água menores, obtendo seu melhor resultado (2,79) na corrente elétrica de entrada de 0,5 A. Através da análise exergética viu-se que a refrigeração utilizando módulos termoelétricos apresentou valores de eficiência exergética de refrigeração muito baixos em relação ao COP (0,043 para o ensaio variando a temperatura da água e 0,051 para o ensaio variando a corrente). Por fim, através da análise exergoeconômica, os resultados mostraram que o custo por unidade de refrigeração diminuiu com o aumento da temperatura da água e com o aumento da corrente de entrada. Ademais, foi feito um ensaio simulando um ambiente a ser refrigerado. Com uma corrente elétrica de 3 A, o protótipo conseguiu baixar a temperatura em 10,4 °C com 5 minutos de funcionamento. Com este estudo, conclui-se que o sistema de refrigeração termoelétrico experimental proposto, nas características e condições dos ensaios, teve resultados satisfatórios e que as análises energética, exergética e exergoeconômica se mostraram eficazes para evidenciar sob quais condições o sistema tem melhor desempenho e menor custo.

The purpose of this work is to study self-oscillatory systems under adaptive external action. This refers to the situation when the phase of the external action additionally depends on the dynamical variable of the oscillator. In a review plan, the results are presented for the case of a linear damped oscillator. Two cases of self-oscillatory systems are studied: the van der Pol oscillator and an autonomous quasi-periodic generator with three-dimensional phase space. Methods. Methods of charts of dynamical regimes and charts of Lyapunov exponents are used, as well as the construction of phase portraits and stroboscopic sections. Results. In a review plan, the results are presented for the case of a linear damped oscillator. Two cases of self-oscillatory systems are studied: the van der Pol oscillator and an autonomous quasi-periodic generator with a three-dimensional phase space. The pictures of characteristic dynamical regimes are described. Scenarios for the development of multidimensional chaos are described. Illustrations are given of the influence of the control parameter, which is responsible for the degree of dependence of the phase on the oscillator variable, on the dynamics of the system at different frequencies of action. Conclusion. The taling into account of the dependence of the phase on a dynamical variable leads to an extension of the tongues of subharmonic resonances, which are weakly expressed in the classical van der Pol oscillator. This is especially noticeable for even resonances of periods 2 and 4. For the generator of quasi-periodic oscillations in the non-autonomous case, three-frequency tori are observed, their regions begin to dominate with an increase in the adaptivity parameter, displacing the tongues of resonant two-frequency tori. A variety of multidimensional chaos characterized by an additional Lyapunov exponent close to zero is discovered, the possibility of developing hyperchaos as a result of destruction is shown.

Published: September 2023

The purpose of this article is to analyze the evidence of twin deficits hypothesis by empirically examining the relationship between trade deficit and budget deficit for the case of FYR of Macedonia. The study employs a vector autoregression (VAR) model as well as a Granger causality test in order to investigate the causal relationship between trade and budget deficit variables using quarterly data for the time period 1998Q1–2017Q4. The econometric results of VAR model disclose that there exists a short term relationship between these two variables, implying that higher trade deficits are associated with higher fiscal deficits. Moreover, the causality test shows a unidirectional relationship, revealing that trade deficit causes budget deficit, whereas budget deficit doesn't cause trade deficit.

Knowledge Management & Loyalty Programs: A Customer Perception Analysis, the Greek Retail Market
Authors: Malamidou K , Spyropoulos T S , Rotsios K
Published: September 2023

The Food Retail sector in Greece is currently facing a number of challenges. From an economic point of view, the austerity programs imposed in Greece since 2010 resulted in losses of retail sales, alongside with bankruptcies and mergers of retail chains. At the same time, technological development creates an environment for innovation in terms of operations and marketing and offers new opportunities to retailers. Additionally, consumers become more involved and active in the purchasing processes. However, Greek consumers are also experiencing a dramatic decline in their disposable income. The study examines the perception of Greek consumers of several marketing efforts based on Information & Communication Technology Systems (ICT) introduced by a Greek food retailer in Northern Greece. More specifically, it investigates the relationship between ICT related marketing efforts, such as loyalty programs, and analytics regarding food control systems and purchases and consumer characteristics such as gender, age, income, status and family size. The study reveals a number of relationships between marketing efforts and consumer characteristics/segments. However, since the relationships are found to be weak, marketing managers are advised to use advanced analytics systems, such as big data technologies, in order to enhance the efficiency of their marketing strategies and approaches. The weak relationships between the parameters examined indicate that marketing efforts have to focus in several consumer sub segments in order to achieve significant results. The study’s sample population is consumers of one of the top food retailers in Greece. The findings contribute to the literature on the use of ICT on marketing strategies and the use of big data. Furthermore, they have practical implications for marketers in the retail food sector, as they reveal the need for a more focused approach to different consumer groups, in order to increase the efficiency of marketing efforts and to achieve maximum results.

Consumer Confidence Linkages Among European Union Countries: Which Countries Tend to Be Followers of Others?
Authors: Medikienė M , Dapkus M , Maditinos D
Published: September 2023

In this study we use hierarchical cluster analysis to identify clusters in terms of consumer confidence and test the hypothesis whether Western and non-formerSoviet-Union Northern countries (Sweden, Denmark or Finland) may be “the core”, while Southern and former USSR countries may be considered as “periphery” in terms of consumer confidence (in respect with Krugman’s “core-periphery” model). Results show that consumer confidence similarities define clusters of EU countries, located in the same sub-region of Europe in cases of all Northern Europe countries and almost all Western Europe countries (excluding Netherlands, Luxembourg and Austria). We find that Southern and Central–Eastern EU countries don’t have their united, single socio–economic behaviour pattern, but rather tend to distribute to various clusters in terms of consumer confidence. Our test for hypothesis of possible “core” and “periphery” countries in terms of consumer show that some of Western and non-former-Soviet-Union Northern countries (in this case we identified Sweden, United Kingdom and Luxembourg) may be considered as “the core”, while the rest Southern and former USSR EU countries may be considered as “periphery”.

The Relationship of Hepcidin, Soluble Transferrin Receptor, Growth Differentiation Factor-15 And Anemia in Multipl Myeloma
Authors: ÖNEÇ Birgül , KÖŞ Durdu Mehmet , ALTUN Gulsah , SUNGUR Mehmet Ali
Published: September 2023

Objective: Multiple myeloma (MM) is a malignant hematological disease and anemia is observed in the majority of patients. Hepcidin, Growth differentiation factor-15 (GDF-15), soluble transferrin receptor (sTfR) have been investigated in many forms of anemia, especially in chronic diseases and cancers. However, there are few studies investigating their role in MM. We aimed to determine the relationship between hepcidin, sTfR and GDF-15 levels in MM patients and their clinical features such as anemia parameters, disease stage and overall survival.

Method: Hepcidin, sTfR and GDF-15 levels, as well as clinical and anemia-related parameters, were analyzed in newly diagnosed MM patients and healthy volunteers.

Result: Although MM patients had significantly lower Hb and Hct levels compared to the control group, none of the GDF-15, hepcidin and sTfR levels showed a significant difference between the groups. Among MM patients, we found that the anemic subgroup had significantly lower hepcidin levels than the non-anemic subgroup. GDF-15, hepcidin and sTfR levels showed weak or moderate positive correlation with each other, while GDF15 was positively correlated with creatinine and sTfR levels were correlated with many parameters such as LDH, CRP, ferritin, albumin, creatinine, Hb and ISS, all of which weak. None of the levels of GDF-15, hepcidin and sTfR had a significant effect on survival.

Conclusion: We suggested that these mediators may play a role in anemia of MM but there is not a clear relashionship as in chronic disease anemia, there may be different mechanisms according to the characteristics of the patient groups.

Published: September 2023

Introduction: Cardiovascular diseases are the main cause of death in the world, and some of these diseases can be controlled or avoided with a healthier lifestyle. These diseases are often associated with the emergence of other diseases such as diabetes mellitus, obesity, high cholesterol levels and high blood pressure. Research has shown that vitamin D deficiency can be a factor that also helps in the appearance of these diseases, since if the serum levels of vitamin D are adequate, it can help in the control and prevention of these diseases.
Objectives: To evaluate the relationship between vitamin D and cardiovascular diseases, specifically systemic arterial hypertension and its effects.
Methods: A systematic review was carried out by searching for original articles in scientific databases: Pubmed, Science Direct, Lilacs and Scielo in English and Portuguese.
Results: No conclusive data were found for the indication of vitamin D supplementation in the treatment of systemic arterial hypertension, due to its lack of efficiency so far, requiring further research to better clarify the subject.
Conclusion: The results obtained do not present conclusive data for the indication of vitamin D supplementation in the treatment of systemic arterial hypertension, due to its lack of efficiency up to the present moment, more research is necessary for a better clarification on the subject.

Authors: Bezerra Marina Rodrigues , Araújo João Luiz Gurgel Mota , Cunha João Ítalo da Silva , Lima Moisés Medeiros de , Martins Daniel Freitas Freire
Published: September 2023

The present study aimed to investigate the influence of spatial and temporal variation on the physicochemical characteristics of water in three urban reservoirs in the city of Caraúbas-RN: Saboia Reservoir, Grande Reservoir, and Santa Bárbara Reservoir. This study can provide relevant information about the quality of these water resources and support actions and policies for the conservation and sustainable use of urban water, both for human consumption and irrigation purposes. The analyses and methods adopted followed the guidelines established in the Standard Methods of APHA. The results show that the physicochemical quality of the analyzed waters is directly affected by spatial and temporal variability, with particular emphasis on conductivity, salinity, chloride, and turbidity. Despite the observed influence, most of the parameters fall within the limits established by current legislation, indicating the possibility of using the water for human consumption and irrigation in accordance with these parameters. However, for a comprehensive and accurate assessment of usability, additional analyses encompassing other physicochemical and microbiological parameters would be required.
On the perceived usefulness and effectiveness of Eduflow as a supplementary tool for online writing instruction
Authors:   Ss. Cyril and Methodius University, Skopje, Stojanovska-Ilievska Natasha
Published: September 2023

This paper centres around the use of Eduflow, a novel online learning management system (LMS) which was introduced in a university-level Academic Writing course in response to the challenges brought about by the mandatory switch from face-to-face to online writing instruction (OWI) over the course of the COVID-19 pandemic. In this paper, Eduflow is piloted with a group of second-year university students of English language and literature at Ss. Cyril and Methodius University in Skopje. These students chose to fulfil their Academic Writing course requirements by compiling a writing portfolio. The rationale behind the use of this platform was the assumption that it would facilitate the online management of all the stages of the essay writing process: Writing a first draft, doing a peer review of essays created by fellow students, considering the comments received from fellow students, reflecting on one’s own writing by doing a self-review, and finally, submitting the final version. The relentlessness of the pandemic led to the continuous application of this learning management system over the course of two entire academic years, each year with a different group of students. An online survey on the perceived usefulness and effectiveness of Eduflow was administered among the second generation of students who used this platform. As this small-scale analysis demonstrates, despite experiencing some easily resolvable minor technical difficulties, these students generally found Eduflow effective and useful as a supplementary tool for online writing instruction and showed particular appreciation for the collaborative peer review experience.

Invoicing under exchange rate risk : the exporting firm
Authors: Broll Udo , Fuchs Frank , Wahl Jack E.
Published: September 2023

The basis for our analysis is a monopolistic risk neutral exporting firm searching for optimum invoicing under exchange rate risk. The exporting firm exposes itself to various risks depending on the selection of the invoicing currency, namely a transaction risk while selecting the currency of the importer (local currency pricing) and an economic risk while selecting the currency of the exporter (producer currency pricing). The resulting risk is different in both cases and can therefore be influenced by the selection of the invoicing currency. (original abstract)

Kelapa sawit (Elaeis guineensis, Jack) merupakan sumber pendapatan bagi jutaan keluarga petani, sumber devisa negara, penyedia lapangan kerja, serta sebagai pendorong tumbuh dan berkembangnya industri hilir berbasis kelapa sawit di Indonesia. Pelepah kelapa sawit merupakan limbah padat yang berasal dari perkebunan kelapa sawit. Kertas adalah bahan tipis yang dihasilkan dengan kompresi serat yang berasal dari pulp. Proses pembuatan pulp adalah dengan cara pemisahan senyawa lignin untuk mendapatkan serat selulosa dari kayu. Penelitian ini bertujuan memanfaatkan pelepah sawit untuk dimanfaatkan pada pembuatan kertas yang sesuai SNI. Tahapan penelitian ini adalah pencacahan, pencucian, perebusan, perendaman NaOH, perendaman H2O2, penghalusan, penambahan talcum, pencetakan dan pengeringan dengan oven pada suhu 75 0C, 80 0C, 85 0C. Sebanyak 64% panelis menyatakan bahwa kertas yang dihasilkan dengan suhu pengeringan 75 0C berwarna putih sedangkan pada suhu 80 0C sebayak 62% panelis yang menyatakan bahwa kertas yang dihasilkan berwarna putih dan pada 85 0C sebanyak 56% yang menyatakan kertas berwarna putih dan sesuai dengan SNI 4733. Tekstur kertas yang dihasilkan pada suhu pengeringan 75 0C ada 76% panelis yang menyatakan kertas yang dihasilkan bertekstur halus sedangkan pada 80 0C ada 66% yang menyatakan bahwa tekstur kertas halus dan pada 85 0C sebanyak 62% yang menyatakan tekstur kertas halus serta sesuai  SNI 0439. Kadar air kertas yang dihasilkan pada suhu pengeringan 75 0C diperoleh rata-rata 1.9%, pada 80 0C hanya 1.8% dan dengan suhu pengeringan 85 0C diperoleh kadar air yang tinggi yaitu sebesar 1.6 %, namun hasil ini masih sesuai dengan SNI 0439 yaitu maksimal 2%. Rata-rata nilai gramatur kertas yang dihasilkan pada suhu pengeringan 75 0C sebesar 76.1 g/m2, pada suhu 80 0C sebesar 79.9 g/m2 dan pada suhu pengeringan 85 0C sebesar 85.3 g/m2 dimana nilai ini masih sesuai dengan SNI 0439 yaitu minimal 50 g/m2.

Aim: Bimaxillary protrusion is a common condition observed irrespective of race and ethnicity and is a chief concern for patients who seek orthodontic treatment. The aim of this study was to compare and evaluate changes in soft tissue structures and incisor positions in class I bimaxillary protrusion subjects undergoing orthodontic therapy when friction and frictionless mechanics were used. Methods: Two groups with a total of 40 patients aged 18–30 years diagnosed with class I bimaxillary protrusion treated by extracting first premolars were considered for this study. Patients treated with friction mechanics were included in Group 1 and those treated with frictionless mechanics in Group 2. The digital lateral cephalograms were calibrated and analyzed using Nemoceph software. Selected landmarks were marked on pre- and post-treatment cephalograms and assessed for intra- and inter-group soft tissue and incisor position changes. Student’s t-test was used to analyze the collected data using SPSS 20 software. Result: Intragroup comparison revealed significant changes in both groups. Inter-group comparison of the selected parameters between groups 1 and 2 showed differences but without any statistical significance, except for the inter-incisal angle. Conclusion: Pre- and post-treatment comparison analysis revealed significant soft tissue changes in both groups. However, the comparison between friction and frictionless mechanics showed no statistically significant changes.
Memória e autoria em Tlaxcala
Authors: Cordiviola Alfredo
Published: September 2023

No contexto da república de Tlaxcala sob a dominação espanhola no período colonial, a historiografia estava destinada a enfatizar as singularidades locais, não só para preservar as memórias relevantes, mas também para garantir os privilégios e a relativa autonomia que a província possuía na organização política da Nova Espanha.  Revisitar as obras pictográficas e pictóricas, os anales, as crônicas, as peças teatrais e outros escritos e representações que conformam essa tradição nos obriga a discutir, e a repensar, a noção de “autor” que se depreende dessas produções. Mesmo quando, em alguns casos, essas obras possam estar atreladas a um nome próprio, colecionador, leitor, copista, continuador, sujeito coletivo, arquivista, compilador, trânsitos entre línguas escritas e oralidades são algumas das atribuições, práticas e características que, de toda forma, devem ser consideradas quando se discute a autoria. Trata-se de atribuições que são certamente diferentes das que se associam à figura do autor nas letras modernas ocidentais. Este trabalho pretende apresentar e discutir essas diferenças, que permitem analisar como se elaboravam os discursos historiográficos a partir de perspectivas e necessidades indígenas, e qual era o estatuto dos escribas, cronistas e pintores encarregados de cumprir essa tarefa.
Michel Foucault e a questão da autoria
Authors: Alves Marco Antônio Sousa
Published: September 2023

A conferência “O que é um autor?”, proferida por Michel Foucault em 1969, é indiscutivelmente uma grande referência nos estudos sobre a autoria. Neste artigo, pretendemos situar a reflexão de Foucault sobre o tema, apresentar suas teses mais importantes e destacar suas principais contribuições para o debate contemporâneo. O foco desta análise será a produção dos anos 1960 do filósofo francês, marcada pelo interesse pela questão da experiência radical com a linguagem e pelas reflexões metodológicas sobre as unidades discursivas, no seio do projeto arqueológico. Nosso estudo dará destaque às teses desenvolvidas em 1969, relacionadas à utilização do nome de autor, ao exercício da função-autor, à ideia de autoria transdiscursiva, à possibilidade de um mundo no qual a função-autor não esteja mais em funcionamento e, por fim, ao caráter ideológico da noção de “autor”.
