Published: November 2022

The investigation of n-butane and n-pentane oxidation in system with two consecutive reactors confirmed the mechanism of phthalic anhydride formation by Diels-Alder reaction between maleic anhydride and C4 unsaturated hydrocarbons. The process is limited by low stationary concentration of C4 unsaturated hydrocarbons in reaction mixture which is connected with high rate of their oxidation to maleic anhydride. It was shown that n-butane oxidation leads to formation of maleic anhydride only but the introduction of unsaturated C4-hydrocarbons on inlet of the second catalytic reactor accompanied by phthalic anhydride appearance on outlet of these two consecutive reactors system. It was established that in case of 1,3-butene introduction in the second reactor the quantity of phthalic anhydride formed is more than in case of 2-butene addition. It was predicted that a decrease of the temperature in the second reactor can leads to an increase the phthalic anhydride selectivity and its yield as result of Diels-Alder reaction effectiveness. This assumption was confirmed by experimental results. In results the method of phthalic anhydride production by the use of two consecutive reactors was proposed. The summary yield of this product on this new process can reach up to 35 mol. %. In the case of n-pentane oxidation the formation of maleic and phthalic anhydrides was observed with excess of first product but the introduction of unsaturated C4-hydrocarbons in the inlet of second reactor leads to an increase of the phthalic anhydride concentration and its selectivity and yield. In result the yield of phthalic anhydride equal to 35 mol. % can be obtained. So, the proposed by us mechanism of phthalic anhydride was confirmed by new experimental results and other pathways for the selectivity and yield of this product can be predicted.

Authors:   Institute for Sorption and Problems of Endoecology of the National Academy of Sciences of Ukraine, Fedoryshyn O.S.
Published: November 2022

The main advantages and disadvantages of solid-phase catalysts for transesterification reactions of oils with alcohols are analyzed. Tests of the sulfonated and phosphated solid - phase catalysts synthesized by us in the transesterification reaction of rapeseed oil with 96% ethanol in order to obtain biodiesel were carried out. The chemical resistance of sulfonated synthetic (S-SCS) and synthesized from natural raw materials (S-KAU) catalysts was compared. The reasons for low chemical resistance of sulfonated carbon-containing materials are determined. Synthetic S-SCS catalysts proved to be the least stable. Regeneration of phosphated samples was performed by washing the catalyst from oil residues and reaction products in a boiling solution of 0.1 M alkali, followed by repeated washing with distilled water to slightly alkaline pH. Then, after drying, the obtained material was used as a source for re-synthesis of the catalyst. The ethanolysis reaction was carried out in autoclaves under pressure at a temperature of 150-160oC with a process duration of 5-7 hours. The ratio of catalyst to starting oil was chosen 1:15 (g : ml). The oil-alcohol ratio was 3: 4, vol. The volume of the autoclave was 45 ml. The maximum conversion under these test conditions in the first cycle for sulfonated catalysts was 100%, and for phosphated - 94%. A carbon-containing catalyst on a ceramic support has been developed, which can be regenerated by firing the carbon-containing material and applying a new one. This catalyst showed the highest chemical resistance, withstanding 7 cycles, while the conversion fell by 14% (from 89 to 75%). For more efficient use of the catalyst, the scheme of flow-circulation installation of transesterification of oils and fats of biological origin with alcohols was proposed.

Published: November 2022

Purpose: The aim of this study was to examine the effect of supervised and home-based clinical Pilates exercises on physical fitness, psychosocial status, and exercise beliefs in healthy women. Methods: Thirty-eight healthy women (mean age=29.95±7.16 years) were divided into two groups: supervised group (N=19) and home-based group (N=19). Physical fitness was assessed with modified push-up, sit-up, sit to stand, anterior plank, lateral plank, Biering-Sorensen, trunk flexors endurance, timed up and go and 6-min walking tests. Body composition was assessed with body mass index and waist to hip ratio. Psychosocial status was assessed with Social Appearance Anxiety Scale (SAAS), Rosenberg Self-Esteem Scale (RSES), Body Image Scale and Exercise Beliefs Questionnaire. Both groups completed a 24-session exercise program for 8 weeks, 3 days a week. Results: After the program, a significant improvement was seen in the modified push-up, sit-up, sit to stand, anterior plank, lateral plank, Biering-Sorensen, trunk flexors endurance tests with SAAS, RSES and Exercise Beliefs Questionnaire scores in the supervised group (p<0.05). In the home-based group, significant improvement was achieved in the modified push-up, sit-up, anterior plank, trunk flexors endurance tests with Exercise Beliefs Questionnaire scores (p<0.05). Comparing delta values, it was observed that there was a significant difference in the sit to stand and anterior plank tests with the Exercise Beliefs Questionnaire scores in favor of the supervised group (p<0.05). Conclusion: It was seen that clinical Pilates exercises, both supervised and home-based, similarly increased endurance and muscle strength, as well as positively affected participants’ perspectives on exercise in healthy women. In addition, clinical Pilates exercises performed under supervision made a difference in both lower extremity strength evaluated by sit to stand test and endurance results evaluated by anterior plank test.

Pusat Studi Mangrove merupakan pengembangan tambak sylfofisheries dengan beberapa jenis mangrove diantaranya adalah Avicennia marina, Rhizophora apiculata, Avicennia alba dan Sonneratia alba. Penelitian ini bertujuan untuk melakukan karakterisasi bakteri pada tutupan mangrove yang berbeda. Serasah yang berlebihan dapat mengakibatkan menumpuknya bahan organik dan meningkatkan derajat keasaman perairan pada tambak silvofishery.  Namun keberadaan bakteri heterotroph yang mampu menguraikan bahan organik diperairan memiliki peran penting dalam mempertahankan keseimbangan ekosistem tambak silvofishery terutama pada petakan dengan persentase tutupan mangrove yang tinggi (>50%). Perencanaan tambak silvofishery dengan menggunakan jenis mangrove yang berbeda diduga akan memberikan hasil yang berbeda, karena adanya perbedaan pada jumlah serasah yang jatuh serta kandungan bahan aktif yang bersifat sebagai antibakteri yang dimiliki jenis mangrove yang berbeda pula.Metode yang digunakan adalah eksperimental skala lapangan dengan parameter Kelimpahan bakteri Heterotrof di perairan dan Kualitas Air yang meliputi pH, suhu dan salinitas.Dari hasil penelitian didapatkan bahwa Kelimpahan bakteri heterotroph pada petakan silvofisheries dengan mangrove Avicennia marina lebih tinggi daripada petakan silvofisheries mangrove Rhizophora mucronata dan parameter kualitas air yang mempengaruhi kelimpahan bakteri heterotroph adalah pH, sedangkan suhu serta salinitas tidak memberikan pengaruh terhadap kelimpahan bakteri heterotroph pada petakan silvofisheries.

Published: November 2022

Effective wayfinding design should efficiently and accessibly provide navigational tools to its user. These tools are multidimensional and engage a complex network of socio-political, cultural, economic, and linguistic issues. This paper interrogates the wayfinding system on Stellenbosch University’s campus – a space where issues regarding linguistic injustice have been prevalent due to the university’s long history with Afrikaans language and culture. The research considers the theoretical perspectives of wayfinding, linguistic landscaping, and spatial justice. These theories were utilised alongside qualitative data collected through interviews with and questionnaires completed by relevant participants on campus. The results revealed that the user experience of the wayfinding system was lacking in effective and efficient accessibility. It was suggested that an amended wayfinding design – one that took into account the balancing of power relations in the campus space – could contribute towards spatial justice and a more welcoming environment for all.

Authors:   Ural Federal University, Ekaterinburg, Russia, Alekhin V. N. , Hussein Abdullah ,   Ural Federal University, Ekaterinburg, Russia
Published: November 2022

Building information modeling (BIM) is one of the most promising recent developments in the architecture, engineering, and construction industry. With BIM technology, an accurate virtual model of a building is digitally constructed. This model, known as a building information model, can be used for planning, design, construction, and operation of the facility. Unfortunately, a lot of critical data gets lost in-between the different stages of the build process, from conceptualization to construction and maintenance. This is the result of converting and translating data between other software solutions and formats. This problem is preventable. By integrating GIS data into BIM models. This article will demonstrate how GIS and BIM can be applied to the construction workflow for buildings and infrastructure, and which benefits can provide this integration for improving the quality of the construction process.

TENSIONS AMONG PORTUGUESES IN METACOMMENTARIES FROM EAST ASIAN INTERNATIONAL STUDENTS IN BRAZIL
Authors: Frazatto Bruna Elisa , Bizon Ana Cecilia Cossi
Published: November 2022

ABSTRACT The aims of this paper are to analyse how East Asian international students narrate tensions in Portuguese language, or Portugueses, through metacommentary, and to foster reflections on the counter-hegemonic potential that language learning comprises, particularly when thinking of the internationalisation agenda implemented by a Brazilian public university. To pursue that, we depart from audio-recorded semi-structured interviews, later manually transcribed, with a Korean and a Japanese undergraduate student during their sojourn. We observed that these tensions in Portugueses arose as students’ communicative repertoires were put to the test, either by them or their interlocutors, in different spaces. Our discussion foregrounds how students, when engaging in various social practices on campus and off-campus, manoeuvre sociolinguistic scales in comments made by themselves or by their interlocutors about ways of speaking Portuguese. We considered that, overall, students resort to ecological factors when doing scales, whilst indexing dominant language ideologies. Moreover, it was also possible to conceive that metacommentary from their interlocutors, particularly from Brazilians, impact (negatively) on students’ perception about their language learning and linguistic practices. To tackle these tensions, we advocate for an internationalisation agenda that envisages language education not only to international students, but also to home students and staff in order to promote different degrees of language and social justice awareness.

Através de uma pesquisa colaborativa na interseção disciplinar entre a antropologia, a sociolinguística e a educação, localizada em um pequeno território da área metropolitana de Boston, marcado por uma antiga imigração açoriana, a análise organiza-se em dois planos complementares: um local, socioespacial e comunitário, em narrativa etnográfica, e outro individual, ancorado na trajetória linguística pessoal, em narrativa autobiográfica. A discussão enfatiza o papel da dimensão ideológica, transversal aos vários pontos analisados, abrindo para uma reflexão crítica sobre português como língua de herança nos EUA.

Abstract The study was conducted to compare the distribution and composition of the Molluscs community in 4 ecosystems (4 sites) in southern of Iraq, namely: (Site 1)- in Euphrates River at Al-Madinah city, (Site 2)- in Shatt Al-Arab at Al-Sharsh area, (Site 3)- in the Garmat Ali River at Al-Mashib area and Site 4- in the Al-seba area. Samples were collected from study sites during a period of January to August 2019. (11) species from the class Gastropoda and (4) species from the class Bivalves, species were predominated in most of the study months which are species: Melenodies nodosa, Bellamya bengalensis and Melanopsis turbculata from Gastropoda and two of the species are bivalve: Corbicula fluminalis and Limnoperna fortunei (Dunker, 1857), and the last species, L. fortunei, was recorded in the current study for the first time in freshwater of Iraq. The total biodiversity values of Molluscs at the Euphrates River at Al-Madinah area (Site. 1), Al-Sharsh area (Site 2), Al-Mashib area (Site 3) and Al-seba area (Site 4) were 3.1, 2.9, 2.4, 1.8, respectively, and It was noted that the highest seasonal densities of the species in the current study were recorded in the winter season, reaching 1013, 905, 762 and 639 individuals / m2 in four sites, respectively.

Abstract Any solid, unprotected, and undefended surface in the aquatic environment will be fouled. Fouling, on the other hand, can affect a wide range of species that can tolerate some epibiosis. Several others, on the other hand, aggressively keep the epibionts off their body surface (antifouling). Antifouling defenses are built into marine plants like seaweed and seagrass. They do have a distinctive surface structure with tightly packed needle-like peaks and antifouling coverings, which may hinder settling bacteria's ability to cling. Chemical antifouling resistance is most probably a biological reaction to epibiosis' ecological drawbacks, especially for organisms capable of performing photosynthesis. The goal of this study was to see how effective natural compounds derived from littoral seaweeds were in preventing fouling. The brown mussel, an important fouling organism, was evaluated in laboratory bioassays against fifty-one populations' crude organic extracts including fort-two macroalgae species. Antifouling activity, exhibited a distinct phylogenetic pattern, with red macroalgae having the largest share of active species, subsequently brown macroalgae. Antifouling action in green seaweeds has never been significant. Seven species showed some level of induced antifouling defense. Our findings appear to back up previous findings about secondary metabolite synthesis in seaweeds, indicating that in the hunt for novel antifoulants, researchers should concentrate their efforts on tropical red macroalgae.
Phytochemistry, allelopathy and anticancer potentiality of Withania somnifera (L.) Dunal (Solanaceae)
Authors: Ahmed H. A. , El-Darier S. M.
Published: November 2022

Abstract Withania somnifera is a wild plant that shows great activity and safety against several human diseases. The current research explored the plant's chemical composition and allelopathic effects on Rumex dentatus (recipient plant). Moreover, anticancer activity is also tested against four types of human cancer cell lines. Chemical analysis of W. somnifera showed a high percentage of saponins and tannins, while glycosides, alkaloids, and flavonoids occurred in the second order. Results of the allelopathic experiments revealed significant inhibition of the R. dentatus plumule and radicle lengths as well as their relative dry weights. In addition, significant reductions in some primary metabolites of R. dentatus, like non-reducing and total sugar as well as soluble proteins, were determined. Cytotoxic potentiality of W. somnifera was also proved against four different cancer lines, namely; human hepatocellular carcinoma cell line (HepG2), human non-small cell lung cancer cell line (A549), human breast cancer cell line (MCF7), and colon cancer cell line (CaCo2) with IC50 value of about 38, 19, 27, and 24 ��g/ml, respectively.

Abstract Background Measuring the venous diameter and choosing a compatible vena cava filter are essential to reduce the risk of complications resulting from implantation of these devices. However, there is little information on how the diameter of the inferior vena cava varies with sex and age. Objectives To determine the influence of patients’ gender and age on their inferior vena cava diameter and the suitability of the different models of available filters. Methods Retrospective analytical study based on computed tomography images. The diameter of the inferior vena cava was measured at 3 points: above the confluence of the common iliac veins, below the renal veins, and midway between these two points (cranial point, caudal point, and midpoint) using Arya® and Carestream PACS® software. The results were classified by sex and age groups. Results CT scans of 417 patients were analyzed: 245 women and 172 men. The diameters at the midpoint and caudal point were, respectively, 19.1 mm and 20.6 mm in women from 81 to 92 years old and were statistically smaller (p< 0.05) when compared to women aged 19 to 40 years (midpoint: 22.7 mm; caudal point: 23 mm). Similar results were seen in men. Venous diameters at the cranial and caudal points in patients aged from 51 to 70 years were statistically larger in men (cranial point: 24.4 mm; caudal point:22.3 mm) than in women (cranial point: 22.6 mm; caudal point:20.8 mm) (p< 0.05). Conclusions A smaller diameter was found for the inferior vena cava in older patients of both sexes and the rate of diameter change was similar among men and women.

Published: November 2022

ABSTRACT Cladocerans, an important zooplankton community, are consumers from the base of the food web of aquatic environments. We investigated the contribution of producers (phytoplankton and periphytic biofilm) and particulate organic carbon (POC). Collections were carried out in lakes of the Upper Paraná River Floodplain, the last stretch free of dams in the second-largest South American basin. Isotope ratios (δ13C and δ15N) were measured, besides the contributions of probable food sources to the cladocerans biomass. The phytoplankton constituted the source of carbon for cladocerans, followed by POC. Thus this work, in addition to emphasizing the importance of cladocerans in nutrient cycling, highlighted the need for the conservation of environments surrounding the lakes as they are the sources of organic matter for aquatic communities. Besides, the analyzed zooplanktonic organisms demonstrated their role in the interconnection between the green and brown food webs, which have been studied separately for a long time.

ABSTRACT Purpose: This study aims to identify how the innovation studies literature addresses the topic of capabilities for service innovation and to propose directions for future research in this field. Originality/value: There is a gap in the literature on service innovation of the combination of capabilities that guarantees the success of service companies considering the characteristics of service innovators. Design/methodology/approach: This study comprises a bibliometric analysis of documents retrieved from Scopus and Web of Science databases. The total sample examined consists of 1523 studies published between 1974 and 2020. The data were analyzed with the Bibliometrix R-package, providing many visualization forms. Additional co-citation analysis was carried out using VosViewer software. Findings: Results indicate a growing discussion about service innovation and capabilities in the period under analysis, but it is still a fragmented theoretical body. There is a great variety of theoretical approaches that have been used to describe capabilities for service innovation. This way, this study contributes to the literature by mapping the current state of the art in the field of service innovation and by identifying its main research themes, which enabled us to propose a research agenda for further development. Finally, we recognize that few studies involve data collected from different geographic regions other than developed countries.

Published: November 2022

RESUMO Introdução: Estudos de caso são fundamentais em metodologia qualitativa. No Brasil, estudos de caso são predominantes em estudos histórico-sociais na área de Relações Internacionais. No entanto, não há preocupação com a rigidez metodológica. Dificilmente são apresentados os critérios de seleção dos casos, as inferências pretendidas com o estudo e a validade interna e/ou externa a partir da utilização deste método. Materiais e Métodos: Este ensaio bibliográfico analisa a literatura internacional dedicada a perscrutar critérios para seleção de casos para estudos qualitativos. A partir da análise da peculiaridade da produção científica do campo brasileiro comparada à internacional, realizamos uma revisão de literatura dos principais tópicos do debate metodológico qualitativo dentro da epistemologia positivista. Resultados: A revisão permitiu elencar os pressupostos para a aplicação adequada da metodologia qualitativa e as vantagens e desvantagens intrínsecas aos estudos de caso únicos e de amostras pequenas. Apresentamos os pressupostos básicos para seleção de casos a partir de três diferentes abordagens qualitativas, separadas por suas lógicas de causalidade: i) emulação quantitativa, probabilística; ii) pragmatismo eclético, mecanicista; e iii) teoria dos conjuntos, determinista. A partir da sistematização das diferentes estratégias para seleção de casos, e a depender do tipo de causalidade pretendida pelo/a pesquisador/a, apresentamos técnicas para essa seleção dentro de cada abordagem exemplificando sua aplicação com publicações recentes. Discussão: Este ensaio bibliográfico faz uma importante contribuição ao debate da metodologia qualitativa em Relações Internacionais no Brasil ao apresentar boas práticas para seleção de casos para auxiliar o desenvolvimento de desenhos de pesquisa mais adequados aos objetivos e métodos empregados. Avançar no debate metodológico é um importante desafio para aumentar o diálogo da produção científica brasileira em Relações Internacionais com a literatura internacional.
O critério de estabilidade de Rayleigh para órbitas circulares em gravitação newtoniana e relatividade geral
Authors: Daniel Luiz H. R. , Vieira Ronaldo S. S.
Published: November 2022

O estudo de órbitas circulares sob a ação de forças centrais ou em espaços-tempos esfericamente simétricos é assunto bastante abordado em cursos introdutórios de mecânica clássica e de relatividade geral, respectivamente. A estabilidade dessas órbitas é comumente apresentada por meio da análise de máximos e mínimos do potencial efetivo para diversos valores distintos de momento angular. Apresentamos neste artigo, de forma didática, o critério de estabilidade de Rayleigh, que permite uma análise equivalente à do comportamento do potencial efetivo porém mais prática, levando em conta o comportamento de uma única função: o momento angular de órbitas circulares em função do raio. Argumentamos que esse critério, que geralmente não é apresentado nas disciplinas mencionadas acima, pode ser naturalmente incluído nas respectivas ementas, enriquecendo o aprendizado dos alunos.
