Published: October 2023

Purpose: The objective of this work was to manufacture, on an industrial scale, sealing blocks, made in the red ceramic industry, incorporating ornamental stone wastes in percentages of 0%, 10% and 20% in the ceramic mass. Theoretical framework: Red ceramics has an important paper in the construction industry. The sealing block is one of the most used products due to its thermal and acoustic insulation power. The state of Espírito Santo is one of the largest producers and exporters of ornamental stones in the country. The processing of these stones generate large amounts of fine waste. These wastes are deposited daily in ornamental stone landfills. Brazil generates around 2.5 million tons of fine waste per year, where the state of Espírito Santo is responsible for 2 million tons. Method/design/approach: The sealing blocks were manufactured by extrusion in the size of 90x190x190 mm, without waste and with ornamental stone waste. After extrusion, the artifacts were dried in an oven for 7 days at 40°C. They were subsequently burned for 72 hours at a temperature of 900°C. Results and conclusion: The results showed that the specimens manufactured with waste showed lower water absorption, which is a positive factor, they also met the geometric characteristics tests determined by the Brazilian standard for ceramic materials. Research implications: Use ornamental stone waste that is deposited in millions of tons in landfills to manufacture red ceramic artifacts and thus contribute to reducing environmental impact. Originality/value: Produce sealing blocks with ten holes in the red clay ceramic industry and certify their technological feasibility through tests established by Brazilian standards.

Published: October 2023

Purpose: Phytochemical analysis of Sapindus saponaria leaves extracts, evaluating their effect on Artemia salina and Aedes aegypti larvae.

Theoretical framework: Dengue is a disease transmitted by Aedes aegypti mosquitoes and considered a serious public health problem. Its control is done through the management of adult forms of A. aegypti, which occurs through the application of synthetic insecticides. However, its constant use has selected populations of insects resistant to chemical products and for this reason alternative solutions are sought, such as the use of phytoinsecticides.

Method/design/approach: Leaves were collected in areas of native vegetation, from which the ethanolic, aqueous and acetonitrile extracts were obtained, in addition to the ethanolic extract fractions, submitted to phytochemical analysis, with A. aegypti and A. salina larvae used to evaluate the toxic effect of extracts and fractions.

Results and conclusion: The ethanol extract showed the greatest diversity of secondary metabolites, the best CL90 and 100% larval mortality, negatively affecting larval time and larval and pupal mortality, in addition to decreasing the number of formed alates. The inhibitory effect is probably linked to the presence of cardiotonic saponins and heterosides, known for their deleterious action in organisms.

Research implications: The research indicates the potential use of Sapindus saponaria leaves in the control of the dengue vector.

Originality/value: Viability of plant strata for vector control, reducing the application of synthetic insecticides and improving environmental quality.

Published: October 2023

Esta pesquisa possui como objeto de estudo Projetos de Intervenção, delimitado no campo da Educação Profissional com mulheres em Curso Lato Sensu. O objetivo da pesquisa esteve em identificar um olhar sobre aspectos operacionais metodológicos utilizados na proposição dos Projetos de Intervenção social utilizados por 18 alunos-cursistas, em sua maioria mulheres, professoras matriculadas no Curso de Especialização em Metodologia da Educação Profissional. O método utilizado nessa pesquisa foi o fenomenológico (Edmund Russerl, 1859-1938), de análise crítica, que se preocupa com a descrição direta da experiência, de como ela ocorre, não como explicação, mas como sua compreensão. A investigação da experiência realizada no referido curso foi desenvolvida em duas Unidades Formativas no ano de 2015. Os resultados apontaram para a utilização de aspectos operacionais e metodológicos formativos de perspectiva socioespacial e de vivência profissional das professoras, alunas do curso de especialização. As considerações finais destacaram que o processo operacional e metodológico diagnosticado tornam as alunas-cursistas professoras da Educação Profissional localizados no Baixo Sul e Leste baiano, imbricadas no mundo da necessidade humana, em que veio a se traduzir na elaboração de seus Projetos de Intervenção Social, os quais poderão trazer a perspectiva de propor novos estudos e intervenções também na Pós-graduação stricto sensu, com saltos para além das Tecnologias Convencionais (TC). Isso vem a potencializar o desenvolvimento regional de pesquisas que passam pelo olhar sobre esses Projetos de Intervenção. O que vem a valorizá-los (Autoras e seus projetos) com suas experiências, seus diagnósticos, não construídos em gabinetes com interesses diversos, mas do campo em que atuam.

Published: October 2023

An influence of the qualitative and quantitative composition, phase structure, and the mode of thermal treatment on antimicrobial activity of various phosphorus-containing compounds of some alkaline-earth metals synthesized by co-sedimentation of a metal salt and ammonium hydrophosphate in a solution of ammonium hydroxide has been investigated. The grain size distribution was checked by the laser grain size analysis, which showed that the mean grain size in the materials obtained by the treatment between 400 and 800℃ ranged between 5.48±2.81 and 126.71±3.68 μm. As seen from the sample weight loss analysis, the greatest loss was achieved for the magnesium compounds and became from 3.84±0.13 % (400℃) to 4.13±0.15 % (800℃). Other phosphorus-containing compounds showed weight losses lesser than 3 % (0.36–2.83 %). Antimicrobial activity of the synthesized compounds was tested for different grain sizes against the following reference strains: gram-positive S. aureus АТСС 25923, gram-negative E. coli АТСС 25922, and yeast-like fungi C. albicans ATCC 885-653. Smaller grains showed a greater antimicrobial activity, while all samples proved some retardation in germs proliferation. Possible approaches to the application of the synthesized compounds as antibacterial fillers for the food paper packaging materials are discussed.

Temporary migration: category of analysis or category of practice?
Authors: Triandafyllidou Anna 
Published: October 2023

<p>Temporariness has become an increasingly salient feature in international migration that presents itself as fragmented, non-linear, including different intermediate stops and multiple returns and new departures. This special issue proposes a new analytical framework that brings together the role of policies defining migrants as temporary and the role of migrant’s own agency in perceiving their migration project as temporary or permanent. The proposed analytical framework covers both low- and high-skilled, legal and irregular migratory flows, and different visa and citizenship regimes. This introduction starts by discussing the relationship between migration and time pointing to its multiple facets. The second section discusses temporary migration as a policy category looking at how it is regulated in more or less flexible regimes, including categories of temporary migrants that are not usually included in temporary migration debates, notably international students or working holiday makers. Section three turns to the lived experiences of migrants and the ways in which they conceptualise their migration (or their migration plans) as temporary or more long term, emphasising how these views can be also changing over time and through the actual migration experience. The final section brings the two strands together and presents the contents of this special issue.</p>

Published: October 2023

Pada era industrial, limbah cair industri menjadi salah satu masalah yang serius. Limbah cair industri yang tidak sesuai dengan baku mutu dibuang secara langsung ke badan air yang mengakibatkan pencemaran lingkungan. Karenanya pengolahan limbah harus ditangani sejak awal selama proses produksi. Salah satu material yang sering digunakan sebagai adsorben dalam proses adsorpsi yaitu silika. Silika merupakan adsorben yang memiliki struktur geometri pori, sifat kimia pada permukaan dapat dimodifikasi dan sangat mudah diproduksi. Silika dapat diperoleh dari beberapa sumber diantaranya yaitu sekam padi dari limbah hasil pertanian. Review ini bertujuan untuk mengetahui kemampuan silika sebagai bahan pengolahan limbah industri. Silika dapat digunakan dalam proses pengolahan limbah cair beberapa industri sepeti batik, laundri, industri tahu dan beberapa limbah industri lainnya. Silika paling efektif diaplikasikan pada pengolahan limbah industri tekstil. Silika mampu mengurangi kekeruhan dan kadar warna limbah cair industri khususnya tekstil. Nilai koefisien penurunan tertinggi sebesar 96,86% untuk warna, sedangkan kekeruhan sebesar 99,31%. Nilai ini didapatkan dari berat campuran silika 5 gram (28,65 %wt), volume limbah 100% dengan kandungan warna 1,123 Co dan kekeruhan 180,5 NTU.
Industrial liquid waste is one of the serious problems in the industrial era. Disposal of industrial liquid waste that is not in accordance with quality standards directly into water bodies can cause environmental pollution. Therefore, wastewater treatment must be handled early during the production process. Silica is one of the most commonly used adsorbents in the adsorption process. This is due to the ease with which silica is produced and the surface properties (pore geometry structure and surface chemistry) that can be modified. Silica can be obtained from several sources, one of which is rice husk which is a waste from agriculture. This review aims to determine the role of silica as an industrial wastewater treatment material. From several articles obtained, silica can be used in the processing of wastewater from batik industrial, laundri industrial, tofu industrial and several other industries. Silica is most effectively used in the textile industry wastewater treatment. Silica can reduce the color and turbidity of the textile industry wastewater. The highest removal coefficient value is 96.86% for color and 99.31% for turbidity obtained from a 5-gram (28.65 %wt) silica mixture mass, 100% waste volume with color content of 1.123 Co and turbidity of 180.5 NTU.

BackgroundCushing disease (CD) may lead to accelerated cardiovascular remodeling and increased mortality. There are suspected differences in the mechanism of cardiovascular dysfunction between males and females with CD. The purpose of this study was to assess the effect of patient sex on the hemodynamic profile assessed via impedance cardiography and echocardiography in patients newly diagnosed with CD.Material and methodsThe 54 patients newly diagnosed with CD (mean age 41 years; 77.8% of females) who were included in this prospective clinical study underwent impedance cardiography to assess specific parameters (including systemic vascular resistance index [SVRI], total arterial compliance index [TACI], Heather index [HI], stroke index [SI], cardiac index [CI], velocity index [VI], and acceleration index [ACI]) and transthoracic echocardiography to assess heart chamber diameters and left ventricular systolic and diastolic function.ResultsMales with CD exhibited higher afterload, with higher SVRI (3,169.3 ± 731.8 vs. 2,339.3 ± 640.8 dyn*s*cm-5*m² in males and females, respectively; p=0.002), lower TACI (0.80 ± 0.30 vs. 1.09 ± 0.30 mL/mmHg*m2; p=0.008), and lower hemodynamic parameters of left ventricular function, with lower HI (9.46 ± 2.86 vs. 14.1 ± 5.06 Ohm/s2; p=0.0007), lower VI (35.1 ± 11.9 vs. 44.9 ± 13.1 1*1000-1*s-1; p=0.009), lower SI (36.5 ± 11.7 vs. 43.6 ± 9.57 mL/m2; p=0.04), lower CI (2.36 ± 0.46 vs. 3.17 ± 0.76 mL*m-2*min-1; p=0.0009), and lower ACI (50.4 ± 19.8 vs. 73.6 ± 25.0 1/100/s2; p=0.006). There were no significant differences between the sexes in left ventricular systolic or diastolic function assessed by echocardiography.ConclusionIn comparison with females with CD, males with CD have a less favorable hemodynamic profile, with higher afterload and worse left ventricular function. Sex differences in cardiovascular system function should be taken into consideration in designing personalized diagnostic and therapeutic management of patients with CD.
