With the increase in life expectancy and the significant incidence of lesions of the musculoskeletal system, both the public and private sectors seek improvements in their products and processes in order to contribute to the health of the population. Every year tons of chicken eggshell (CES) from domestic consumption are released in environment and the present work aims the production of a synthetic ceramic bone substitute using the eggshell as a source of calcium ions. According to the methodology, 5, 10, 15 and 20 mol% of iron ions were used and the characterization assays demonstrated the formation of a double calcium iron phosphate - Ca9Fe(PO4)7. MG63 cells were cultured on test specimens to cell viability assay and to each doped group analyzed, verifying cell compatibility with the studied compounds, as well as a good adhesion profile. Scanning electron microscopy (SEM) of the cells showed that material surface favored cell adhesion and the results demonstrated that the production of the compounds were viable to Ca9Fe(PO4)7 phase. So, in the future, it will be possible to have a final comprehensive biological compatibility of the prototype for further in vitro and in vivo assays. system population CES (CES methodology 5 10 1 2 mol Ca9FePO47.

The composites of poly (butylene adipate co-terephthalate) / poly (lactic acid) (PBAT/PLA) blend and montmorillonites functionalized using imidazole-derived ionic liquids with different carbon chain sizes (butyl, octyl, and dodecyl) proved to be a promising alternative for improving the thermal and mechanical properties of the polymer blend. Functionalization of montmorillonites by ionic liquids was confirmed by increasing the basal spacing, and spectroscopical and thermal analysis evidence. The composite synthesis was carried out by casting technique generating homogeneous polymeric films. X-ray diffraction analyses suggested that montmorillonite functionalization with the ionic liquid of the butyl carbon chain fostered exfoliation and incorporation of the clay into the polymer. Furthermore, an increase in the thermal stability and mechanical properties of the material was observed. The other composites formed between the PBAT/PLA blend and the montmorillonite functionalized by ionic liquids of higher carbonic chain showed micro composites formation. Thus, their thermal and mechanical properties had no significant improvements. butylene coterephthalate co terephthalate co-terephthalate lactic acid PBATPLA PBAT PLA (PBAT/PLA imidazolederived imidazole derived butyl, (butyl octyl dodecyl spacing evidence films Xray X ray Furthermore observed formation Thus improvements

ABSTRACT Planting is considered one of the most essential steps in coffee growing. Lack of uniformity in planting may compromise future operations. Therefore, verifying planting operations quality is fundamental to optimizing production processes and reducing costs. This study aimed to investigate planting techniques through Statistical Process Control (SPC) and aerial images. Carried out in two areas, managed manually and semi-mechanized in the Bom Jardim Farm (MG - Brazil). Data were collected through Remotely Piloted Aircraft (RPA). Quality control charts and density maps were used to identify variations in distribution and spacing between plants and planting rows. It was found that the planting carried out manually was 4.7% wider than projected due to spacing reduction from 0.5 m to 0.48 m. The semi-mechanized system displayed a deficit of 7% compared to the projected planting system, using 0.55 m between plants. The density map showed the most significant planting alignment variations. Despite displaying lower results than the manual system, the semi-mechanized system improvements are valid for their minimal average variations. Thus, correcting points found outside the limits can increase the efficiency of semi-mechanized planting. growing Therefore costs SPC (SPC images areas semimechanized semi mechanized MG Brazil.

ABSTRACT The search for new technologies capable of providing benefits to healthy eating is a global goal. The consumption of foods rich in carotenoids can prevent serious health problems. Thus, the availability of foods high in carotenoids that are accessible to the majority of the population is essential. Lettuce (Lactuca sativa L.) is a suitable species for biofortification research based on genetic improvements. In this study, we aimed to select and obtain hybrid lettuce populations with high agronomic potential and biofortified carotenoid content. Ten lettuce lines registered in the “BG α Biofort” software were selected for hybridization. The crosses used to obtain the hybrids involved two strains rich in at least one of the pigments (chlorophyll and carotenoids), and 24 experimental hybrids were obtained. A total of 37 genotypes (strains, hybrids, and commercial cultivars) were evaluated using a randomized block design for agronomic variables and chlorophyll and carotenoid content. Hybrids 12 (UFU-189#3#4#1 × UFU MC BIOFORT 2) and 25 (UFU66#4#2 × UFU-189#3#4#1) had the potential to produce dual-purpose populations (yield and carotenoid biofortification). Hybrid 27 (UFU66#4#2 × UFU MC BIOFORT1) exhibited the best pigment balance. Thus, F2 hybrids 12, 25, and 27 should be obtained to produce new cultivars of biofortified red and green lettuce for curly, american, mini, and romaine lettuce segments. goal problems Thus essential Lactuca L.

RESUMO A busca por novas tecnologias capazes de proporcionar benefícios para uma alimentação saudável tem sido meta mundial. A presença de alimentos ricos em carotenoides pode ser fundamental para prevenir sérios problemas de saúde. Aliar alimentos com altos teores de carotenoides e acessíveis para a maior parte da população é fundamental. A alface (Lactuca sativa L.) se apresenta como uma espécie adequada para investir em pesquisas com biofortificação a partir de melhoramento genético. Assim, o objetivo com este estudo foi selecionar híbridos de alface visando à obtenção de populações com potencial agronômico e biofortificadas para carotenoides. Dez linhagens de alface cadastradas no Software “BG α Biofort” foram utilizadas nas hibridações. Os cruzamentos para obtenção dos híbridos foram planejados envolvendo duas linhagens ricas em pelo menos um dos pigmentos (clorofila e carotenoides) sendo obtidos 24 híbridos experimentais. Foram avaliados 37 genótipos (linhagens, híbridos e cultivares comercias) em delineamento em blocos casualizados quanto as variáveis agronômicas e teores de clorofila e carotenoides. Foi verificado que os híbridos 12 (UFU-189#3#4#1 × UFU MC BIOFORT 2) e 25 (UFU66#4#2 × UFU-189#3#4#1) possuem potencial para obtenção de populações de duplo propósito (produtividade e biofortificada para carotenoide). O híbrido 27 (UFU66#4#2 × UFU MC BIOFORT1) foi o que apresentou maior equilíbrio para pigmentos. Sugere-se a obtenção de populações F2 dos híbridos 12, 25 e 27 visando a obtenção de novas cultivares de alfaces biofortificadas vermelhas e verdes, para os segmentos de alface crespa, americana, mini e romana. mundial saúde Lactuca L.

ABSTRACT The mechanized cutting of sugarcane requires improvements, as cutting tools can affect the longevity of sugarcane fields and increase production costs. Furthermore, these tools can increase the energy demand of machines in the field. This study evaluated the sugarcane harvester performance equipped with different basal cutting devices: impact cutting (blades) and continuous cutting (saws) in three commercial sugarcane production areas. The experimental design was completely randomized in a 3 × 2 factorial scheme with six repetitions. Effective fuel consumption and harvesting capacity were evaluated. The saws increased fuel consumption per area by 3.9 and 8.9% per Mg harvested. The crop’s yield characteristics determine harvesting systems’ energy demand. For yields above 90 Mg ha-1, energy demand has stabilized up to 120 Mg ha-1. The fuel demand for harvesting ranged between 1.0 and 1.2 L Mg-1 of harvested material. Regardless of the cutting system, each Mg requires 37.3 kJ of energy to be removed from the field. improvements costs Furthermore field devices blades (blades (saws areas repetitions 39 9 3. 89 8 8.9 crops crop s systems ha1, ha1 ha 1, 1 ha-1 12 ha1. 1. 10 0 Mg1 Mg- material system 373 37 37. 8. ha-

RESUMO O corte mecanizado da cana-de-açúcar necessita de aprimoramentos, visto que as ferramentas de corte podem afetar a longevidade dos canaviais e aumentar os custos de produção. Além disso, essas ferramentas podem aumentar a demanda energética das máquinas no campo. Este estudo avaliou o desempenho de colhedoras de cana-de-açúcar equipadas com distintos mecanismos de corte basal: corte por impacto (lâminas) e corte contínuo (serras) em três áreas comerciais de produção de cana-de-açúcar. O consumo efetivo de combustível e a capacidade efetiva de colheita das máquinas foram avaliados em cada tratamento. O delineamento experimental adotado foi inteiramente casualizado em esquema fatorial 3 × 2 com seis repetições. As serras aumentaram o consumo de combustível por área em 3,9 e 8,9% por Mg colhido. As características produtivas da cultura determinam a demanda energética dos sistemas de colheita. Para produtividades acima de 90 Mg ha-1, a demanda energética estabilizou-se até 120 Mg ha-1. A demanda de combustível para a colheita variou entre 1,0 e 1,2 L Mg-1 de material colhido. Os resultados mostram que independente do sistema de corte, cada Mg de cana colhida necessita em média de 37,3 kJ de energia para ser retirado do campo. canadeaçúcar açúcar aprimoramentos disso campo basal lâminas (lâminas (serras canadeaçúcar. açúcar. tratamento repetições 39 9 3, 89 8 8,9 colhido ha1, ha1 ha 1, 1 ha-1 estabilizouse estabilizou se 12 ha1. 1. 10 0 Mg1 Mg- 373 37 37, 8, ha-

ABSTRACT: The structure of the root system of the conilon coffee tree has improved over the years through propagation, genetic, and agronomic studies in response to demands for improvements in plant development, production, and survival of the species. Scientific research plays an important role in generating technologies and the security of applications. However, there is a need to refine the content generated to analyze discoveries and trends on the subject. Therefore, the present study conduct a bibliometric review and analysis on the main contributions of relevant studies, researchers, organizations, and countries in academic research on the rooting of Coffea canephora in the Web of Science (WOS) database. Data from the WOS database published between 1982 and 2021 and systematized in the VOSviewer software showed a set of 92 articles, the majority of which originated in Brazil and France, with the main groups being the Brazilian Agricultural Research Corporation, the Federal University of Viçosa, and CIRAD. The study was divided into five areas: genetic diversity, asexual propagation, nematology, tolerance to water stress, and micropropagation. However, in the context of climate changes and its impact on the production and longevity of Brazilian coffee farming, research focused on the root system has increased significantly, integrating it into lines that explore and integrate topics such as climate risk, water management, drought tolerance, and drip irrigation, including reflections on the performance of coffee agronomy.

ABSTRACT Plant growth regulators play an essential role in plants’ biochemical processes. In this study, foliar spray was applied using three growth regulators, gibberellic acid (GA3), naphthalene acetic acid (NAA), and 6-benzyl amino purine (BAP), to investigate their effects on wheat (Triticum aestivum L.) ‘Giza-171’ yield traits and grain biochemical constituents, including sugars, carbohydrates and protein. The assessed growth regulators (GA3, NAA, and BAP) were applied at 100 and 150 mg L-1 concentrations. The results indicated significant improvements in wheat grain yield and 1000-grain weight, which increased by 15.40% and 24.78%, respectively, using GA3 at 150 and 100 mg L-1. In addition, the highest contents of protein and carbohydrates were observed with samples treated by the foliar application of NAA at 150 mg L-1 and BAP at 100 mg L-1, respectively. The fat content in wheat grains increased by 1.97% and 2.73% with foliar spray with 150 mg L-1 NAA and 100 mg L-1 BAP, respectively. The lipid profile showed cis-linoleic acid was the primary fatty acid, followed by palmitic acid; the content of linoleic acid slightly increased with GA3 treatment to 50.42%, while palmitic acid significantly increased with 100 mg L-1 NAA. The total saturated and unsaturated fatty acids recorded 33.64% and 66.30%, respectively; the 150 mg L-1 NAA treatment had the lowest saturated fatty acid content. The SDS-PAGE profiles showed that growth regulators significantly enhanced the wheat protein where new bands appeared, especially in 100 mg L-1 GA3 and 100 mg L-1 BAP treatments. The applied growth regulators improved wheat yield, contents of some compounds, and nutritional value.

Resumo As vigas de madeira lamelada colada (MLC) fabricadas com barras de aço coladas podem alcançar melhorias no seu desempenho mecânico e os efeitos da disposição das barras de aço na seção transversal são de interesse tecnológico. Esta pesquisa objetivou a avaliação do comportamento mecânico de vigas com reforços simétricos (zonas de compressão e de tração) e vigas com reforços assimétricos (zona de compressão), sob condições de carregamento impostas ao estado limite de serviço. Portanto, vigas de MLC com taxas de reforço variando de 0,5% a 4% foram simuladas pelo método dos elementos finitos. Em relação às vigas sem reforços, as flechas das vigas reforçadas assimetricamente resultaram até 31,5% menores e, as vigas com reforços simétricos foram mais eficientes, cuja redução das flechas foi de até 45%. Comparativamente ao arranjo simétrico das barras, a distribuição assimétrica proporcionou uma redução de até 10,5% na tensão normal da zona de compressão da MLC. A armadura disposta de forma assimétrica contribuiu efetivamente para o aumento da rigidez da viga e foi mais eficiente na redução das tensões normais na zona compressiva, evitando com isso o escoamento inicial da madeira.

Abstract Glued laminated timber (glulam) beams manufactured with glued steel bars can achieve improvements in their mechanical performance and the effects of the arrangement of steel bars in the cross-section are of technological interest. This study aimed to evaluate the mechanical behavior of beams with symmetric reinforcements (compression and tension zones) and beams with asymmetric reinforcements (compression zone), under loading imposed at the serviceability limit state. To achieve this goal, glulam beams with reinforcement ratios ranging from 0.5% to 4% were simulated using the finite element method. When compared to the nonreinforced beams it was found for the deflections that the asymmetric reinforcements provided reductions of up to 31.5% and the cases with symmetric reinforcements were more efficient, with deflection reductions of up to 45%. In comparison to the symmetric arrangement of the bars, the asymmetric distribution provided a reduction of up to 10.5% in the normal stress of the glulam beam compression zone. The asymmetrically arranged reinforcement effectively contributed to increasing the stiffness of the beam and was more efficient in reducing normal stresses in the compressive zone, thus preventing the initial yielding of the wood.

ABSTRACT Objective: To describe the evidence of Platelet Rich Plasma (PRP), Stem cells therapy (SCT) and Extracorporeal shockwave therapy (ESWL) for the treatment of Peyronies disease (PD), including information from the main urological society guidelines. Materials and Methods: A literature review of PubMed articles published between 2000 and 2023 was conducted, utilizing keywords such as "Peyronie's Disease", "Penile curvature", "Platelet Rich Plasma", "Stem cells", and "Extracorporeal shockwave therapy". Only full-text articles in English were included, excluding case reports and opinions. Results: A considerable number of clinical trials were conducted using PRP penile injections for therapy of PD, showing reduction of curvature, plaque size and improvement in quality of life. Preclinical studies in rats have shown the potential benefit of adipose-derived stem cells, with improvements in erectile function and fibrosis. Human studies with mesenchymal stem cells demonstrated promising results, with reduction of curvature and plaque size. ESWL effects on PD were investigated in randomized clinical trials and demonstrated no significant impact in curvature or plaque size, but reasonable effect on pain control. Conclusion: Restorative therapies has emerged as an innovative treatment option for PD and the results from current studies appear to be promising and demonstrated good safety profile. Unfortunately, due to scarce evidence, PRP and SCT are still considered experimental by American Urological Association (AUA) and European Association of Urology (EAU) guidelines. ESWT is recommended, by the same guidelines, for pain control only. More high-quality studies with long-term follow-up outcomes are needed to evaluate efficacy and reproducibility of those therapies.

Abstract Research which evaluates Social Housing (SH) in Brazil often points out unfavorable conditions expressed by residents, in terms of the residential unit and common spaces, as well as surroundings. Participatory processes to improve projects are considered essential for political, social and economic reasons, and user values need to be prioritized. Processes to develop improvements for existing SH, that include residents as protagonists, with active participation, may guide more effective actions. However, participatory processes for home and public area renovations require procedures to effectively achieve their technical objectives and meet the needs and desires of their residents with feasibility of implementation. This research developed a case study with the participation of residents of a small SH project in Campinas - SP, with a specific focus on improvements for the children's leisure areas. The study involved the public targeted, children living in the analyzed SH complex, in defining their leisure space through dynamics and playful activities. Qualitative results are presented of this participatory process, involving children. Knowledge gained is methodological, with lessons learned for the planning and development of participatory co-design projects with children.

Resumo Pesquisas que avaliam Habitação de Interesse Social (HIS) no Brasil em geral apontam condições desfavoráveis expressas pelos moradores em relação à sua moradia, em termos de unidade habitacional e espaços comuns, assim como seu entorno. Processos participativos para melhorias são considerados essenciais por razões políticas, sociais e econômicas, priorizando os valores do usuário. Considera-se que o desenvolvimento de processos de introdução de melhorias de HIS existentes, no qual o morador é protagonista,participando ativamente, pode orientar ações efetivas. No entanto, processos participativos com foco em melhorias residenciais e em áreas comuns necessitam de procedimentos que de fato atinjam objetivos técnicos e atendam as necessidades e desejos dos moradores, priorizando a viabilidade de execução. A pesquisa desenvolveu um estudo de caso com participação de moradores de um conjunto habitacional em Campinas, SP, com foco específico na área recreativa de uso infantil. O estudo envolveu o público-alvo, crianças moradoras do conjunto habitacional, na definição do seu espaço de lazer, a partir de dinâmicas e atividades lúdicas.

RESUMEN El karaguata es un arbusto de la familia de las bromelias del cual se extrae fibra a fin de producir distintos productos, utilizado como recurso ancestral por las comunidades indígenas del Gran Chaco. La presente investigación tiene como objetivo la descripción del avance de los últimos años del uso del karaguata, teniendo a las comunidades de los Ayoreos de Carmelo Peralta y a los Nivaclé de Boquerón como casos de estudio. El método empleado es de enfoque cualitativo, nivel descriptivo de diseño etnográfico; la técnica es de análisis documental. Por medio de estos estudios se tiene como resultado que estas comunidades aborígenes han adquirido un cierto grado de tecnología y la apertura a un nuevo mercado de comercialización que pueden ofrecer soluciones económicas de desarrollo sustentable. Aunque se obtienen resultados positivos se requiere también tener en cuenta algunos aspectos de suma importancia a fin de sostener las mejoras significativas, como por ejemplo, el aprovisionamiento de la materia prima y el cuidado del valor simbólico y sociocultural de la producción hecha por los pueblos originarios. El artículo es un estudio introductorio a otros que pueden realizarse a futuro y que tengan como enfoque principal el examinar a más profundidad la producción, distribución y comercio del karaguata a nivel país.

ABSTRACT Karaguata is a shrub from the bromeliad family from which fiber is extracted in order to produce different products, used as an ancestral resource by the indigenous communities of the Gran Chaco. The objective of this research is to describe the progress in recent years in the use of Karaguata, taking the communities of the Ayoreos of Carmelo Peralta and the Nivaclé of Boquerón as case studies. The method used is a qualitative approach, descriptive level of ethnographic design; the technique is documentary analysis. Through these studies, the result is that these aboriginal communities have acquired a certain degree of technology and the opening to a new marketing market that can offer economic solutions for sustainable development. Although positive results are obtained, it is also necessary to take into account some extremely important aspects in order to sustain significant improvements, such as, for example, the provision of raw materials and the care of the symbolic and sociocultural value of the production made by the native peoples. The article is an introductory study to others that may be carried out in the future and whose main focus is to examine in more depth the production, distribution and trade of karaguata at the country level.

Abstract Introduction. There is a great human concern about antibiotics resistance due to their inappropriate use as growth promoters in animal husbandry. Objective. To evaluate the effect of a high level of zinc as a substitute to antibiotics in nursery pigs. Material and methods. The study was carried out from June to August 2022 in the province of Chiriqui, Panama. The experimental period was composed of three phases with 14 days per phase. The nursery pigs (n= 54) were distributed to one of three treatments with six replicates per treatment and three pigs per replicate. The treatments were: 1) control diet, which was formulated to meet the nutritional requirements for nursery pigs; 2) similar to treatment 1, plus 200 mg of amoxicillin/kg of feed and 40 mg of florfenicol/kg of feed during phase 1 (P1) and phase 2 (P2), respectively; and 3) similar to treatment 1, plus 2000 ppm and 1600 ppm of zinc during P1 and P2, respectively. In phase 3 (P3), all pigs were fed a common diet. Results. The supplementation of zinc improved the average daily gain in all phases. Pigs fed zinc diet had better F:G ratio in P2 compared to pigs fed antibiotic diet (p < 0.05). A higher concentration of hemoglobin and percentage of monocytes was found in pigs fed with higher level of zinc than the other treatments (p < 0.05). Furthermore, Pigs fed the antibiotic, or the control diet had a lower percentage of fecal dry matter compared to those supplemented with zinc. (p < 0.05). Conclusion. The supplementation of high levels of zinc exerted improvements, in comparison to the antibiotic, in terms of hemoglobin concentration, incidence of diarrhea and weight gain in pigs during 42 days after weaning.

En la fase 3 (P3), todos los cerdos fueron alimentados con una dieta común. Resultados. La suplementación con zinc mejoró la ganancia de peso en todas las fases. Los cerdos alimentados con zinc tuvieron mejor relación F:G en P2 en comparación a los cerdos suplementados con antibiótico (p < 0.05). Se encontró una mayor concentración de hemoglobina y porcentaje de monocitos en cerdos alimentados con zinc que en los otros tratamientos (p < 0.05). Los cerdos alimentados con antibiótico o la dieta control tuvieron un menor porcentaje de materia seca fecal en comparación a los suplementados con zinc (p < 0.05). Conclusión. La suplementación de altos niveles de zinc ejerció mejoras, en comparación al antibiótico, en cuanto a la concentración de hemoglobina, incidencia de diarrea y ganancia de peso en cerdos durante los 42 días posteriores al destete.

Abstract: The purpose of this article is to achieve optimal coordination for timed overcurrent relays modeled in a test system. The traditional adjustment that is usually used in the field is taken as the base criterion to determine the improvements achieved with the implemented optimization methods. Optimal parameters are determined for two timed overcurrent relays modeled on the IEEE 13-node test system using PowerFactory software. The optimization algorithms are coded in Python. PowerFactory links with Python to generate interoperability between the algorithm and the electrical system. Satisfactory results are achieved from the COA and GSA algorithms with a reduction of more than 50% in relay operating times.

Resumen: El objeto de este artículo es conseguir la coordinación óptima para los relés de sobrecorriente temporizados, modelados en un sistema de prueba. El ajuste tradicional que se emplea usualmente en el campo se toma como criterio base para determinar las mejoras conseguidas con los métodos de optimización implementados. Se determinan parámetros óptimos para dos relés de sobrecorriente temporizados modelados en el sistema de prueba de 13 nodos de la IEEE mediante el software PowerFactory. Los algoritmos de optimización son codificados en Python. Gracias a la interfaz que presenta PowerFactoy con Python, cada algoritmo se ejecuta dentro del sistema eléctrico. Se consiguen resultados satisfactorios de los algoritmos COA y GSA con una reducción de más del 50 % en los tiempos de operación de los relés.

Abstract This action research study focused on determining the contribution of digital reading through the Edpuzzle platform to improve reading comprehension in 21 fifth-grade students from a municipal elementary school in Chile. It was carried out over seven sessions during which reading comprehension activities in Edpuzzle were used to identify specific information. Data were collected through statistics provided by Edpuzzle, a Likert scale, and two focus groups. Although the results did not reveal significant progress in the evaluated skill, most participants expressed a positive perception of their performance during the interventions. Therefore, these findings may be relevant for those seeking to use online platforms like Edpuzzle to improve students' reading comprehension, as despite the lack of evident improvements, participants enjoyed the activities and experienced a sense of achievement.
