Published: May 2024

Purpose. Today, aeration tanks are widely used to treat industrial and municipal wastewater. Assessing the efficiency of water treatment in aeration tanks under different operating conditions is an important task. To solve this problem, it is necessary to have mathematical models that allow to quickly obtain data on the effect of treatment in aeration tanks. The main objective of this work is to develop a numerical box model to determine the efficiency of wastewater treatment in an aeration tank. Methodology. For mathematical modeling of the biological wastewater treatment process in a bioreactor, zero-dimensional material balance equations are used, which are written in relation to the concentration of substrate, activated sludge, and dissolved oxygen in wastewater. The Monod model is used to calculate the substrate oxidation process. The Euler method is used to integrate the modeling equations. A simplified model of biological water treatment in a bioreactor is considered, which makes it possible to obtain an analytical solution to the problem. The obtained analytical expression makes it possible to quickly determine the change in the concentration of dissolved oxygen in wastewater depending on the change in the concentration of activated sludge in the bioreactor. The constructed numerical model makes it possible to determine the dynamics of changes in the concentration of contaminants, activated sludge and oxygen in wastewater during their stay in the bioreactor. Findings. A tool for theoretical evaluation of the efficiency of biological wastewater treatment in an aeration tank is proposed. A numerical model has been built that allows determining the concentration of dissolved oxygen, substrate and activated sludge at the outlet of the aeration tank. Originality. An effective numerical model has been developed that allows to quickly calculate the dynamics of wastewater treatment in a bioreactor and, based on this information, to evaluate the efficiency of the reactor. Practical value. The constructed mathematical model can be useful in the reconstruction of biological wastewater treatment facilities, as well as at the design stage of bioreactors to take into account their operation under different operating conditions. A computer program has been developed that implements the constructed numerical model. The results of a computer experiment are presented.

Authors: Manafov E. K. , Huseynov F. H.
Published: May 2024

Purpose. The article is devoted to the creation of traction motor protection by modern methods and means based on a programmable logic controller (PLC). Methodology. To simulate motor fault monitoring in laboratory conditions, magnetic field and temperature sensors were installed on a small powerful induction motor, and then the data obtained from the sensors in normal and overloaded motor modes were analyzed. Based on the research, protection methods were developed. Findings. Previously used simple motor protection systems based on components such as timers, contactors, electromagnetic switches, voltage and current transformers were slow and inaccurate, and had low sensitivity. However, the production of PLCs and their application in this industry has eliminated these problems. The intensive operation of motors as the main executive equipment requires the creation of modern automated protection systems to ensure their reliable and stable operation. Originality. The paper improves the method of protection of traction motors based on the use of programmable logic controllers. In addition to the voltage and current parameters, the proposed method involves monitoring the magnetic field. It also provides for the possibility of adjusting the protection response time. As a result, in the event of overload, short circuit, and other non-standard situations, the improved method provides the system with the ability to make more accurate and reliable decisions. Practical value. The TIA Portal software package has modeled a traction motor protection system by temperature and current and considered its practical application. To make such systems more effective, in the future, comprehensive protection systems based on the diagnostic state of the traction motor can be developed. In addition, an effective system can be created by providing SCADA control of the engines of several vehicles simultaneously.

Abstract This study aimed to evaluate the osteogenic potential of hydroxyapatite (HA), Alginate (Alg), and Gelatine (Gel) composite in a critical-size defect model in rats. Twenty-four male rats were divided into three groups: a negative control with no treatment (Control group), a positive control treated with deproteinized bovine bone mineral (DBBM group), and the experimental group treated with the new HA-Alg-Gel composite (HA-Alg-Gel group). A critical size defect (8.5mm) was made in the rat's calvaria, and the bone formation was evaluated by in vivo microcomputed tomography analysis (µCT) after 1, 15, 45, and 90 days. After 90 days, the animals were euthanized and histological and histomorphometric analyses were performed. A higher proportion of mineralized tissue/biomaterial was observed in the DBBM group when compared to the HA-Alg-Gel and Control groups in the µCT analysis during all analysis periods. However, no differences were observed in the mineralized tissue/biomaterial proportion observed on day 1 (immediate postoperative) in comparison to later periods of analysis in all groups. In the histomorphometric analysis, the HA-Alg-Gel and Control groups showed higher bone formation than the DBBM group. Moreover, in histological analysis, five samples of the HA-Alg-Gal group exhibited formed bone spicules adjacent to the graft granules against only two of eight samples in the DBBM group. Both graft materials ensured the maintenance of defect bone thickness, while a tissue thickness reduction was observed in the control group. In conclusion, this study demonstrated the osteoconductive potential of HA-Alg-Gel bone graft by supporting new bone formation around its particles.

Published: May 2024

Abstract This in vitro study aimed to determine the efficacy of dentin bonding agents in preventing color changes following Regenerative Endodontic Procedures. One hundred twenty bovine incisors were endodontically prepared and randomly assigned to a two main factors design: application of a dentin bonding agent (Scotchbond Adper, 3M ESPE, St Paul, MN, USA) in the pulp chamber (Group 1, n=60) versus no bonding intervention (Group 2, n=60), and five levels of intracanal medication (n=12/subgroup): Triple antibiotic paste (TAP), double antibiotic paste (DAB), calcium hydroxide (CH), modified triple antibiotic paste (TAPM), and Control (CTL). Color changes were measured over 28 days at multiple time points (1, 3, 7, 14, 21, and 28 days) using the CIEDE2000 formula to calculate the color difference (ΔE00) from baseline (T0). The ΔE00 quantifies the perceptible color difference between the initial and final tooth color, with lower values indicating less discoloration. The results were analyzed using repeated measures ANOVA-2 and post-hoc Holm-Sidak tests. The TAP subgroups, both with and without the bonding agent, exhibited the highest color variation. However, a pulp chamber seal with a bonding agent showed a protective effect against discoloration compared to no seal, even though complete prevention was not achieved. All groups demonstrated ΔE00 values beyond acceptable interpretation thresholds for clinical application, primarily driven by a reduction in lightness (L*) and a decrease in redness (a* value, shifting towards green). In conclusion, while the pulp chamber seal with a bonding agent mitigated TAP-induced discoloration, it did not eliminate it.

ABSTRACT: The intestinal microbiota has an important role in animal health. Therefore, prebiotics have gained interest in the scientific community for their role in manipulating populations of intestinal microorganisms. Among prebiotics, there is Smallanthus sonchifolius Poepp. Endl (yacon) root, which can be ingested in natura or in different forms, such as flours and extracts. This prebiotic has been associated with beneficial effects in different diseases, including metabolic (like type 2 diabetes) and immunological disorders. Thus, mouse models of human diseases caused by immunological factors have been used to better understand the prebiotic effects of yacon. Since prebiotics interfere with animal microbiota, it is important to take into consideration the quality level of mouse facilities. In this way, the beneficial effects of a yacon root pulp were tested in a mouse model of allergic asthma and, considering how animal facility conditions could affect those results, we performed experiments both in conventional facilities and specific pathogen-free (SPF) ones. Our results showed that better prebiotic effects were observed in a SPF facility than in a conventional one and, in some cases, evidence of yacon beneficial effects was observed exclusively in a SPF facility. For example, there were reductions of 63.6% and 58.0% in IgE and eosinophils, respectively, in immunized/yacon-treated animals compared to immunized mice only. Taken together, our results not only showed the beneficial effects of yacon root pulp in an asthma model but also demonstrated the relevance of performing experiments with prebiotics in SPF facilities.

Published: May 2024

ABSTRACT: Due to the economic importance of maize, it is essential to evaluate the performance of genotypes under environmental variations (years, locations, and seasons). Consequently, researchers have scrutinized genotype-environment (G×E) interactions to ensure reliability in genotype recommendations. Furthermore, when a G×E interaction exists, adaptability and stability analysis can be performed. This analysis enables one to identify genotypes with predictable responses and adaptability to environmental variability. Hence, this study sought to determine if there is a G×E interaction and evaluate the response of 16 maize genotypes across seven environments through adaptability and stability analyses. Seven experiments were conducted with 16 maize genotypes using a randomized complete block design with three replications. Tassel length (TL), tassel branch number (TBN), tassel dry matter (TDM), and grain yield (GY) were evaluated. Individual and joint variance analyses were performed, along with the F-test at a 5% significance level. The complex parts of the interaction between genotypes and pairs of environments were estimated, followed by adaptability and stability analyses using the Eberhart and Russell method. A genotype-environment interaction was found for TL, TBN, TDM, and GY, indicating that genotypes respond differently in various environments. However, considering all four traits, there is no indication of the ideal genotype.

Published: May 2024

Abstract The objective was to evaluate the behavior of melon genotypes (Cucumis melo L.) in the physical, chemical and biochemical quality of melon fruits as a function of electrical conductivity irrigation water levels (ECw). The experimental design adopted was randomized blocks in a 5 x 3 factorial scheme with five replications. The first factor was represented by five salinity levels (0.5, 1.5, 3.0, 4.5, and 6.0 dS m-1) and the second factor by accessions A35, and A24, and the hybrid Sancho. The physical, chemical and biochemical variables showed a reduction in production, with smaller fruits, with less weight, smaller cavity, with increased pulp thickness for Sancho. Vitamin C and yellow flavonoids increased indicating antioxidant power against ROS. The genotypes showed similar post-harvest behavior, however, the hybrid Sancho stood out over the others, possibly because it is an improved material. Accession A24 presented physiological and biochemical responses that classify it as intolerant.

Published: May 2024

Abstract At present more than 50% of the human population of Planet Earth, live in urban areas. The natural environment is changed considerably by cities: increase of population, productions of tons of waste, daily, change of biodiversity. The relationships human-nature were disrupted in cities due to the artificial construction of infrastructure. In order to protect biodiversity and recover nature in cities, Urban Forest Parks, as part of green infrastructure are a very important action. At the same time the psycology of urban populations can be improved. The use of Urban Forest Parks to improve social relations, education, physical activities in older adults can improve their cognitive ability and performance.
Estado e agronegócio no Brasil: a oficialização de uma imagística
Authors: Severo Marconi
Published: May 2024

Resumo Para além do seu aspecto econômico-produtivo, o agronegócio é um fenômeno sociocultural e político. Embora não seja um setor homogêneo (como evidenciam os seus conflitos setoriais internos), nem por isso deixa de mobilizar uma imagística comum fundamentada na figura do produtor rural produtivo. Ao analisar sua relação com o Estado, através da dimensão oficial do seu discurso e da perspectiva de algumas lideranças do setor, é possível perceber que a sua hegemonia cultural e o seu pragmatismo político visam ao controle do aparelho estatal como condição necessária para legitimar legal e socialmente o seu discurso no e sobre o meio rural brasileiro, não raro sem excluir a pretensão de atingir a sociedade como um todo.
O Canto da Machadinha: mito, ritual e história em um gênero de arte verbal krahô
Authors: Packer Ian
Published: May 2024

Resumo Este artigo é dedicado à análise da performance e da poética de um gênero de arte verbal krahô (povo ameríndio falante de uma língua da família Jê e que vive no norte do Tocantins) denominado Kàjre jarkwa, o “Canto da Machadinha”. Em um primeiro momento, recupera-se parte da história recente e profunda desse importante artefato ritual timbira a fim de se destacar alguns elementos centrais para a compreensão de sua matéria narrativa e dispositivo dialógico de enunciação. Em seguida, o foco se volta para a análise de fenômenos tais como paralelismo, indexicalidade e multiposicionalidade a fim de se mostrar como a agência ritual produz uma equivocidade ontológica que transforma o estatuto de seus enunciadores e permite que a Machadinha e outros personagens míticos ganhem voz no presente.

Abstract Objectives: to evaluate the association between the time to initiate the first skin-to-skin contact (SSC) and the daily practice time with the rates of late-onset sepsis in newborns ≤1,800g. Methods: a multicentric cohort study was carried out at the neonatal units located in three Brazilian geographic regions. The SSC time was recorded in individual files by the hospital staff and the newborn’s parents. Maternal and neonatal data were obtained from medical records and through questionnaires applied to the mothers. Data analysis was carried out using a tree algorithm classification, which divided the data set into mutually exclusive subsets that best described the variable response. Results: 405 newborns participated in the study, with an average of 31.3 ± 2.7 weeks and 1,412g (QR=1,164-1,605g) as a median birth weight. The first SSC was carried out within 137 hours of life (≤5.7 days) was associated with a lower rate of late sepsis (p=0.02) for newborns who underwent daily SSC of 112.5 to 174.7 min/day (1.9 to 2.9h/day), with a reduction in the sepsis rate from 39.3% to 27.5%. Furthermore, the duration of SSC >174.7min/day (>2.9h/day) was relevant (p<0.001) for newborns who weighed >1,344g, with a reduction in this rate from 24.1% to 6%. Conclusions: SSP has been proven to be significant in reducing late-onset sepsis rates in preterm newborns, especially when carried out in a timely manner (≤5.7 days) and prolonged (>2.9h/day).
Estimating the intra-urban wage premium for a Metropolitan Area in a developing country
Authors: Campos Rodger Barros Antunes , Azzoni Carlos Roberto
Published: May 2024

Abstract We estimated the intra-urban wage premium and its attenuation with a balanced panel of workers in the metropolitan area of Sao Paulo, Brazil. There are few studies dealing with the agglomeration effects on wages in developing countries, especially focusing on a fine geographical scale, as we consider in this paper. We geocoded the employment data on a grid of 9,071 cells of 1 km² and compared wages in the adjoining cells. We use Geographically Weighted Regressions to determine the size of the rings based on the AIC minimization method. We use worker and firm observable characteristics and fixed effects of firm, worker, and cell to deal with the selection of firms and workers. The estimated intra-urban wage premium ranges from 0.8% and 1.1%, depending on the size of the cells (0.5, 1, 2, and 4 km2). The attenuation effect is observed but restricted to 3 km from the inner cell and is stronger for less educated workers.
Economia política como medicina. A demonstração anatômica fisiocrata na Filosofia Rural
Authors: Müller Leonardo André Paes
Published: May 2024

Resumo A Filosofia Rural (1763) é a obra mais importante da Fisiocracia. Assinada por Mirabeau, mas escrita em conjunto com Quesnay, ela é descrita pelos autores no capítulo 7 como uma “demonstração anatômica” do corpo político representado no Quadro econômico. O presente artigo leva a sério essa proposta e busca expor, de modo esquemático, as balizas do projeto fisiocrata como uma medicina social, a saber, sua anatomia, fisiologia e etiologia e o modo como elas fundamentam sua clínica, isto é, um diagnóstico, um prognóstico e uma terapia.
Sistema de parceria e mercado de trabalho na colônia Dona Francisca: novas evidências sobre a colonização europeia no sul do Brasil na transição da escravidão, 1851-1876
Authors: Ferreira Luiz Mateus da Silva
Published: May 2024

Resumo Este artigo examina o mercado de trabalho na colônia Dona Francisca, um dos mais importantes núcleos de colonização europeia do Brasil no século XIX. A análise traz à luz novas evidências a respeito do emprego da mão de obra imigrante durante a transição da escravidão no Brasil. Especificamente, o artigo revela a utilização do sistema de parceria como forma de relação de trabalho livre na colônia de povoamento Dona Francisca, no sul do Brasil. Além disso, este estudo demonstra que, apesar da elevada relação terra-trabalho e de os colonos da Dona Francisca serem pequenos proprietários de terras, a maioria dos imigrantes estabelecidos nessa colônia trabalhava em atividades remuneradas paralelas à agricultura, dedicando-se apenas parcialmente ao cultivo de suas propriedades. Assim, as evidências apresentadas neste artigo sugerem que o mercado de trabalho da colônia Dona Francisca constituiu uma exceção à hipótese formulada por Evsey Domar, em conhecido artigo publicado em 1970.
Vanishing Market Power
Authors: Guthmann Rafael R.
Published: May 2024

Abstract Perfect competition can be approximated in an environment with differentiated goods, heterogeneous firms, and frictions of trading. This paper considers an environment where sellers sell differentiated goods to buyers, and frictions of trading are represented by the buyers having incomplete consideration sets of the sellers in the market. Besides selling differentiated products, some sellers are more “prominent” and so are present in a larger number of buyers’ consideration sets. However, despite these imperfections, as the average number of sellers in the buyers’ consideration sets expands, the sellers’ market power vanishes and the equilibrium of the market approximates competitive conditions.

ABSTRACT Periodontitis is an inflammatory clinical condition caused by dysbiotic biofilm that results in progressive destruction of periodontal attachment and can lead to tooth loss if left untreated. Objective: To evaluate the clinical efficacy of high-power diode laser as an adjunct to mechanical instrumentation in periodontal pockets of a patient with generalized, stage III, grade C periodontitis. Methods: 126 sites of a patient were examined at the Clinical Research Laboratory (LabClin) of the Federal University of Campina Grande (UFCG), where the parameters of probing depth (PD), clinical attachment level (CAL) and bleeding on probing (BoP) were evaluated at the beginning of the study and after 3 and 6 months of basic therapy. All sites received non-surgical periodontal treatment which corresponds to scaling and root planing (SRP) and coronary polishing. The deep periodontal pockets with PD ≥ 5 mm, received the adjuvant therapy with diode laser light. Results: There was a significant improvement of periodontal parameters of PD, CAL and BoP in all treated sites. In those with PD ≥ 5 mm, the results were similar, with statistically significant reduction of PD, CAL and BoP before and after treatment. After 6 months, all periodontal pockets with PD ≥ 5mm were reduced to values lower than 3. Conclusion: The irradiation of deep pockets with high-power diode laser proved to be effective as adjuvant therapy to SRP in patients with generalized, stage III, degree C periodontitis.

Published: May 2024

ABSTRACT Paroxysmal Hemicrania is a trigeminal autonomic cephalalgia described as a severe and strictly unilateral pain, which occurs in paroxysms at orbital, supraorbital and/ or temporal region. A 45-year-old woman presented to an orofacial pain specialist reporting severe, burning, throbbing, strictly right-sided headache associated to ipsilateral autonomic symptoms and orofacial pain. The pain was perceived on the maxillary region followed by pain spread to the head. Interdisciplinary evaluation, along with absolute responsiveness to indomethacin and normal Brain Magnetic Resonance imaging, led to the diagnosis of primary Episodic paroxysmal hemicrania with facial representation and myofascial pain of masticatory muscles. Dentists should be aware of paroxysmal hemicrania with facial representation and the possibility of temporomandibular disorder coexistence, in order to avoid misdiagnosis and inadequate management. Paroxysmal hemicrania may be first perceived on the face and may be associated with interparoxysmal pain. In these cases, efficient anamnesis and clinical evaluation followed by interdisciplinary approach is needed.

Authors: Reyes Claudio Llanos , Pizarro José Antonio González , Sarmiento Yenny Pinto
Published: May 2024

RESUMEN Este artículo examina el desarrollo histórico del concepto de flexibilización laboral en Europa occidental, especialmente durante las décadas de 1970 y 1980. A través de la revisión y análisis de investigaciones sobre la flexibilización laboral y sus implicaciones, nuestro objetivo es enriquecer la comprensión histórica de las transformaciones en el mundo del trabajo. Desde la década de 1970, la crisis de los sistemas laborales en Occidente desafió los modelos de protección al trabajador y la seguridad social. Las disparidades existentes entre los países europeos en lo que respecta a la flexibilización laboral y sus múltiples repercusiones en el ámbito social pueden atribuirse a diversos factores, tales como la influencia de los sindicatos, las regulaciones laborales y las políticas gubernamentales. Explorar la evolución histórica de la flexibilización laboral como concepto es esencial para entender cómo ha llegado a convertirse en un marco conceptual que guía las reformas y cambios en el ámbito laboral.

Published: May 2024

Abstract This article aims to recognize and dialogue with the production of knowledge, practices and, in particular, with undergraduate teaching in occupational therapy in territorial and community contexts, through the systematic mapping of articles, dissertations and theses published between 2012 and 2022. Bibliographic search was carried out in November 2022, through the SciELO virtual library, the Brazilian Digital Library of Theses and Dissertations (BDTD), the Brazilian Institute of Information in Science and Technology (IBICT) and the databases: Web of Science, Scopus and Latin American and Caribbean Literature in Health Sciences (LILACS). 40 productions were eligible, of those, 29 articles and 11 dissertations/theses. The results were analyzed based on thematic analysis, whose topics were: What is territorial and community teaching? Where does it occur? What pedagogical strategies? Who teaches? What challenges do you face? What are the guiding concepts? The results point to interdisciplinary, interprofessional, collaborative teaching with important attributes such as the teaching-learning-assistance process in the territory and in territorial services, including actors such as students, professionals, teams and the community, in addition to the teacher who proposes, articulates and mediates of this teaching. We conclude that the mapping presents a general overview of this teaching, highlighting encounters between theories and practices, from different sub-areas of occupational therapy, which, in addition to teaching, propose actions to transform educational, social, cultural and health conditions. However, we noticed that there are gaps in the literature in the area that explain how the concepts are linked to this training, producing specific reflections on the profession in different sub-areas.

Published: May 2024

ABSTRACT One of the main stages in bubalinoculture is breeding calves, because this phase is defined by the quality of the animals that will be the future property matrices. The breeding phase extends from birth to weaning, and is delicate and precise; consequently, attending to characteristics of extreme importance in dairy farming activity such as behavioral and health aspects will aid these animals to express all of their genetic potential. Since this life phase of the animal does not generate immediate economic return to the producer, it ends up not receiving the necessary attention, contributing to low zootechnical indices and high production costs. Adopting adequate management practices is essential for the productive development of the animal that will guarantee the future good productivity of the farm. In view of the above, the objective of this study is to present the management of buffalo calves through a literature review, emphasizing that proper feeding, correct management and disease prevention are fundamental to ensuring the well-being and health of calves. These factors, together with a clean and safe environment, can maximize the productive potential of these animals. It is therefore essential that producers are well-informed and prepared to properly care for these animals during this crucial phase of their lives.

Abstract The objective of this work was to evaluate the physiological and anatomical characteristics of garlic cultivar leaves that indicate tolerance or susceptibility to environmental factors. The experiment was conducted in a greenhouse in a completely randomized design, with eight treatments (cultivars). The evaluated cultivars were Amarantes, BRS Hozan, Caçador, Crespo, Chinês Folha Fina, Chonan, Gigante Roxo Escuro, and Ito. The following physiological variables were evaluated: net photosynthetic rate, stomatal conductance to water vapor, transpiration, internal and external carbon, and water use efficiency. The anatomical characteristics were analyzed with a microscope coupled to a camera. The Chinês Folha Fina, Chonan, Gigante Roxo Escuro, and Crespo cultivars showed higher mean photosynthetic rates and thicker photosynthetic tissues than the others. The Chonan and Crespo cultivars stood out for their higher photosynthetic rates, higher stomatal indices, thicker cuticle and epidermis, and larger mesophyll intercellular spaces, which are characteristics common to plants tolerant to water deficit.

Abstract The objective of this work was to characterize chilling tolerance in rice mutant families of the M4 generation, at the seedling stage. Two experiments were carried out: chilling tolerance was evaluated in 43 mutant families, in the 'BRS Querência' original genotype, and in 19 commercial genotypes. In Experiment II, 8 mutant families from Experiment I, 'BRS Querência', and a mutant of the M5 generation were tested. In both experiments, seedlings were evaluated under two conditions: 10°C for seven days and 25°C for seven days. In Experiment I, the induced mutations in rice led to varied responses in chilling tolerance traits, with some M4 mutant families outperforming the original genotype. Experiment II highlighted the impact of mutations on chilling-tolerance, particularly in terms of leaf discoloration and plant recovery. Mutant families of the M4 generation differ from the original genotype 'BRS Querência' in chilling tolerance at the seedling stage. The mutant families M36, M54, and M56 and 'BRS Querência' show genetic similarity, indicating a lack of chilling tolerance during the seedling stage. The mutant families M17, M21, M22, and M26 are promising for rice breeding programs because they present chilling tolerance. The M30 mutant family exhibits the best performance for all analyzed traits, indicating chilling tolerance at the seedling stage.

Abstract The objective of this work was to evaluate the effect of the use of the Murashige & Skook (MS) and Linsmaer & Skoog (LS) media and of filter caps on culture flasks on the morphological and physiological characteristics of basil cultivars in vitro, as well as to determine the composition of the essential oil of plants acclimatized in pots. For the evaluation of the cultivation media, cultivars Anise, Cinnamon, Grecco a Palla, and Italian Large Leaf were used. The Anise, Cinnamon, Italian Large Leaf, and Maria Bonita cultivars were used for the evaluation of the use of filter caps. The composition of the essential oils of cultivars Anise, Cinnamon, and Italian Large Leaf was also evaluated. The basil seedlings showed a higher aerial-part dry mass and a lower hyperhydricity rate when grown in the MS medium. The flasks without filter caps produced seedlings with lower contamination rates. When acclimatized in pots, cultivars Limoncino and Anise presented the tallest plants with the largest crown diameters. In the composition of essential oils, methyl cinnamate and linalool stood out in cultivar Cinnamon, methyl chavicol in Anise, and linalool in Italian Large Leaf. In the in vitro cultivation, the evaluated cultivars present a higher aerial-part production in the MS medium and a lower contamination without the use of filters, whereas, in the pots, the composition of essential oils varies according to the cultivar.

Textile-reinforced concrete (TRC) has gained a lot of attraction in recent years. Adequate bond between the phases in this system allows to transfer high loadings, thus enabling high performance. The terminus textile reinforcement, however, comprises many different types of fabrics, which differ in their chemical composition, geometry, surface properties etc., and thus exhibit substantially different bond properties. In the course of RILEM’s Technical Committee 292 work on TRC it was found that a comprehensive understanding of the complex interactions between individual parameters is still lacking. This is amplified by the fact that different types of textile reinforcement are preferably used in different regions of the world. This paper therefore attempts to compile findings from literature on the bond in TRC. The database used was created in the course of the TC work. Additional papers of relevance were identified by scanning scientific web databases. The different influencing parameters are given in this paper in a hierarchical order, starting from the level of the individual constituents (filament and matrix) to impregnated fabrics and the influence of textile manufacturing and architecture on the bond. Finally, by mapping all the cited literature used in this paper based on grouped keywords the complex intercorrelations are visualised.
Research on the control of high-fill roadbed with tunnel slag in karst sections
Authors: Ge Hongsheng , Liu Liping
Published: May 2024

In this study, based on the Kaihua section of the G205 (China) national highway reconstruction project, the construction area of the K4+550–K4+940 section was chosen to conduct settlement control research on the high-fill roadbed of the karst section within the construction area. The viability of using clayey gravel and tunnel slag as roadbed fill was evaluated through laboratory soil tests. The construction technology of grouting was used to manage the substructure of the karst section. After installing prestress anchors on the top of the foundation, a ‘layered’ filling scheme was utilised to fill the tunnel slag and clayey gravel. The Flac3D simulation software was used to contrast the deformation curves of key nodes on unanchored and anchored roadbeds. The test results indicate that the California bearing ratio satisfies the requirements of the specification and that the uniaxial compression strength of the tunnel slag satisfies the requirements of the specification when the clayey gravel is near the optimal moisture content and dry density and when the compaction is controlled within 94%. The use of prestress anchors can strengthen the rock and soil layers of the foundation and reduce the plastic zone distribution. This paper provides a corresponding engineering experience for the treatment of high-fill roadbeds in karst areas.

Cemitérios que não aderem às normas estabelecidas pelo CONAMA para implantação e operação podem representar fontes significativas de impactos ambientais, afetando a saúde pública e o meio ambiente. Durante o processo de decomposição, os cadáveres geram efluentes, tanto gasosos quanto líquidos, com potencial para causar impactos no solo, corpos d'água superficiais e subterrâneos, e na qualidade do ar. A avaliação ambiental destes espaços se faz necessária com o intuito de identificar os principais impactos e posterior adequação. Inserido neste contexto, esta pesquisa tem por objetivo realizar um diagnóstico da qualidade ambiental em um cemitério localizado na Zona Sul da cidade de São Paulo. Para o desenvolvimento realizou-se visitas in loco com registro fotográfico, análises de campo e consideração das implicações da contaminação do solo, ar e águas subterrâneas, além da análise de diretrizes relacionadas a regulamentações específicas para cemitérios. Verifica-se que o empreendimento necessita de manutenção, principalmente na questão da limpeza e predial, devido irregularidades presentes nas vias de circulação e sepulturas, limpeza das canaletas de águas pluviais, jazigos destruídos e/ou danificados, vegetação invadindo os túmulos e pavimentação e a não utilização de geomembranas, visando combater a contaminação do solo e lençol freático.
