La cultura de Ventura Rodríguez y la biblioteca de su sobrino Manuel Martín Rodríguez
Authors: Blanco Mozo Juan Luis
Published: October 2024

En los últimos años la figura de Ventura Rodríguez (1717-1785) como arquitecto ha sido estudiada con éxito por la historiografía moderna. Su biografía, sin embargo, ha carecido de datos fundamentales para su estudio. Con los nuevos documentos aportados en este trabajo se ha intentado situar su personalidad dentro de una familia de arquitectos originaria de la localidad madrileña de Ciempozuelos. El análisis de la biblioteca de Manuel Martín Rodríguez en 1787, heredero de los bienes de su tío Ventura Rodríguez, descubrirá las influencias que tuvo su arquitectura. El clasicismo del Barroco romano está representado en su biblioteca con varios libros sobre la arquitectura antigua y moderna de Roma. Del mismo modo tuvo conocimiento de la nueva idea de la antigüedad a través del estudio de los descubrimientos arqueológicos más emblemáticos de su época. Se plantea la posibilidad de que el giro neoclásico, siempre sobre el sólido sustrato del barroco romano, que sufrió su arquitectura en los últimos años fuera motivado por la observación y lectura de los repertorios de los restos exhumados de ciudades antiguas como Herculano o Palmira.
International debt metrics from the perspective of financing the green agenda
Authors:   Council of the National Bank of Ukraine, Shcherbakova Olena , Stepaniuk Yevhen ,   Secretariat of the Council of the National Bank of Ukraine
Published: October 2024

The article summarizes the public debt policy issues in the context of financing climate change measures, and suggests priorities and mechanisms of fiscal, debt and sectoral policies to ensure sufficient financing of the green agenda. Authors have emphasized the trilemma between achieving climate goals, maintaining fiscal sustainability, and ensuring political capacity. It has been found that even under favorable external financial conditions, climate-vulnerable countries face a constant premium to the cost of borrowing. As a result, developing countries with high levels of debt and climate vulnerability are caught in a vicious circle of growing investment needs for climate- sustainable structural transformation and significant dependence on increasingly expensive debt financing, which leads to a combination of deteriorating debt sustainability and insufficient funding for climate change challenges. Authors argue for a comprehensive multilateral policy aimed at reforming the international debt architecture and increasing the amount of available financing for climate change adaptation under a government-led framework. Achieving common goals requires a carefully calibrated combination of climate change mitigation instruments based on enhanced domestic revenue mobilization, in particular through carbon pricing, more efficient spending on transfers, green subsidies and investments, and regulatory measures. Authors propose a comprehensive approach to implementing climate change mitigation policies, including the implementation of a fiscal strategy, sectoral policies to prevent climate change, and stimulating private investment. Emphasized the importance of developing further tools for incorporating climate policy into debt sustainability analysis.

Published: October 2024

Introduction and objective: Both the illness itself and hospitalisation due to COVID-19 are potentially traumatic experiences, especially when the course of the disease is severe. Resilience has been identified as a crucial factor in the process of successfully coping with traumatic events and may protect against the development of symptoms of post-traumatic stress disorder. The aim of this study was to determine the role of resilience in the prevention of post-traumatic stress disorder symptoms in patients requiring hospitalisation due to COVID-19. Materials and methods: A total of 138 patients (59 women, 79 men; mean age: 52.34 years; standard deviation, SD = 12.46) hospitalised at the University Hospital in Krakow were included in the study, which was conducted 7–8 months after their COVID-19 diagnosis. The PTSD Checklist for DSM-5 (PCL-5) and the Resilience Measurement Scale (SPP-25) were administered, and stepwise multiple regression analysis was used in the predictive models. Results: A total of 31 participants (22.5%) met the criteria for probable post-traumatic stress disorder symptoms. The study participants were characterised by a moderate level of resilience (5th sten), with women exhibiting lower levels than men. Higher levels of resilience were associated with lower severity of PTSD symptoms. A significant predictor of post-traumatic stress disorder symptoms was “Tolerance for failure and treating life as a challenge”. Conclusions: Resilience has an impact on the severity of symptoms of post-traumatic stress disorder. Specifically, the dimension of “Tolerance” within resilience appears to be an important protective factor against post-traumatic stress disorder symptoms after hospitalisation for COVID-19. Patients hospitalised with severe course of COVID-19 exhibit a moderate level of resilience, with men demonstrating higher resilience levels than women.
Reflective and ruminative types of self-consciousness among young adults with perfectionistic personality traits
Authors: Józefczyk Kacper , Duda Norbert , Mącik Dorota
Published: October 2024

Introduction and objective: Motives for self-observation can be diverse. This study aims to determine whether young adults with perfectionistic personality traits are closer to the ruminative or reflective type of private self-consciousness. Materials and methods: The study involved 183 healthy individuals aged 18–30 years (M = 20.87, SD = 3.24), with women accounting for 57%. The Big Three Perfectionism Scale (BTPS) by Smith and the Rumination-Reflection Questionnaire (RRQ) by Trapnell and Campbell were used. Results: The results indicate that perfectionism is positively related to the ruminative type of self-consciousness. Reflexivity, as cognitive curiosity about oneself, represents a more mature way of functioning for which perfectionism is unnecessary. In contrast, perfectionism is strongly associated with critical self-examination and has much in common with the ruminative form of self-consciousness. Self-critical perfectionism thus becomes a strategy whereby increased rumination, i.e. ruminating about past and potential failures, leads individuals to believe they are preventing future failures. Conversely, grandiose perfectionism protects against rumination. Individuals do not perceive their mistakes and, therefore, do not ruminate about them. Conclusions: Based on the Three Big Perfectionism Scale, the results confirm the association of the ruminative type of private self-consciousness with perfectionism and its absence between the reflective type and perfectionism.

Authors: Ladeira  João Damasceno Martins
Published: October 2024

O artigo analisa o lançamento de um aplicativo de streaming, o Peacock, apresentado pela Comcast em 2020. O serviço é relevante devido a seu potencial para introduzir um modelo voltado à apropriação definitiva dos sistemas convencionais de broadcast pelo on-line. Isso decorre da capacidade desse serviço de reter um traço importante da televisão: a diversidade de gêneros, agregando jornalismo, programas de variedades e conteúdo esportivo. Aborda-se esse caso recorrendo à arqueologia das mídias, apropriando-se do conceito de remediação como forma de observar a captura do passado aqui em curso.
A experiência sensível no site da Comissão Nacional da Verdade (2011-2014)
Authors: Leone dos Santos Roberval de Jesus
Published: October 2024

O problema de pesquisa deste artigo é verificar se a experiência sensível, no sentido de Emanuele Coccia, se manifesta plenamente no site publicado pela Comissão Nacional da Verdade, criada pela Lei no 12.528, de 18 de novembro de 2011. O principal objetivo é verificar se o site contribui para uma justiça de transição. Os resultados do exame mostram que a experiência sensível, no site, é limitada e que, portanto, o Brasil, mesmo considerando que a criação do site foi um dos maiores esforços para promover a memória e a verdade, ainda tem de cumprir ou mesmo iniciar um longo caminho para vencer todas as etapas de uma justiça de transição em relação à ditadura vigente nos anos de 1964-1985

Contraceptives are methods used to prevent unwanted pregnancy and sexually transmitted diseases. It is used by both males and females that are sexually active. This study aimed at examining the awareness and use of contraceptives among female undergraduates in Federal University Oye Ekiti, Nigeria. It examined the age of sexual debut as well as frequency of contraceptives use. The study adopted the Theory of Planned Behavior (Ajzen & Fishbein, 1980) as its theoretical framework. It was a survey carried out among female undergraduates in the six faculties of the university at Oye, Ekiti. The sample size was 200 respondents randomly selected from females in the faculties. Questionnaire was the main instrument of data collection while books and academic journals were used as supporting sources. Data collected was coded and analyzed with SPSS version 2.0. The study concluded that female undergraduates of FUOYE were mostly between 16–25 years (85.5%), majority (69%) had their first sexual intercourse between 16 and 18 years, 100% of the respondents were aware of and (58%) use contraceptives frequently to prevent unwanted pregnancy and sexually transmitted diseases. Majority got to know about contraceptives through their friends (45.5%) and 20% equally (boyfriends and Google). Majority (76.5%) had only one sexual partner and (58%) had sex frequently. Therefore, the study recommended that the government should encourage female undergraduates with monthly stipends aimed at encouraging them to focus on their education and maintain academic stability instead of having multiple sexual partners that will distract them from reaching their goals.

Authors:   University of Nigeria, Nsukka, Enugu State, Nigeria, Okoh Joel Ogechukwu
Published: October 2024

Electoral processes in many African countries including Nigeria, are faced with the challenges of conducting free, fair, credible and violence-free elections. Political violence has become a stain on Nigerian democracy. This paper therefore examined the impact of political violence on national security in Nigeria. The paper adopted the descriptive analytical approach. This study found out that Political violence in Nigeria is now a stain in our democracy that is now seen as a political structure and strategy for employment during elections and the use of weapons during elections have an aftermath impact on the national security. Consequently, some recommendations were made by the researcher. The Independent National Electoral Commission (INEC) has to take conscious and strategic actions against political violence in the country (Nigeria), due to the fact that action and inaction of the government of the country plays a very important role in either stopping or continuing the menace. Appropriate security network and intelligence should be organized to monitor electoral activities of the country to mitigate incidences of violence. The Independent National Electoral Commission should conduct free, fair and credible elections in Nigeria while the political parties and their candidates should ensure strict compliance with electoral regulations of the country (Nigeria).
Outro sem eu? Por uma filosofia não identitária, feminista, global e pluriversal
Authors: Johanson Izilda
Published: October 2024

Resumo: Trata-se da investigação da relação entre produção de conhecimento e de colonialidade, tendo por guia a questão da alteridade no contexto epistemológico da subjetividade moderna. Buscando compreender como se dá a relação entre subjetividade e identidade (ou mesmidade), consequentemente, entre objetividade e alteridade (ou outridade) na modernidade, procurarei responder criticamente, de uma perspectiva feminista, perguntas essenciais à prática filosófica na contemporaneidade: a) em que consiste ser o “outro do eu” nessa filosofia mais consagrada entre nós e para quem o cânone é, como tal, legado máximo do legítimo e do verdadeiramente filosófico? b) quais podem ser as possibilidades desses “outros” virem a se relacionar de maneira dialógica e positiva com essa filosofia canônica? c) que consequências se pode tirar dessas respostas, do ponto de vista da constituição de uma multiplicidade integrada de saberes globais e pluriversais, dos quais todos os seres vivos do planeta Terra, e o próprio planeta, poderiam verdadeiramente se beneficiar?

Published: October 2024

Abstract: This investigation demonstrates the effect of alkali modification of titanium on the metabolism of human osteoblasts. Polished titanium discs were subjected to alkalinization protocols with NaOH (5M) at 60°C or 120°C. Surface topography and roughness were evaluated using scanning electron microscopy (SEM). Osteoblasts were seeded onto titanium discs, followed by cell adhesion and viability analysis, total protein and collagen production, and alkaline phosphatase (ALP) activity. Gene expression of tumor necrosis factor-alpha (TNF-α) and beta-defensin 3 (HBD3) was evaluated after inflammatory stimulus with lipopolysaccharides (LPS) of Porphyromonas gingivalis (1 μg/mL) for 4 h. Discs subjected to modification with NaOH showed major irregularities, especially for 120°C-protocol. Increased adhered cell number was observed for surfaces modified by NaOH. Osteoblasts cultured on modified surfaces showed higher cell viability, total protein and collagen synthesis, and ALP activity than that of cells cultured on the polished discs. Osteoblast response to LPS exposure showed increased TNF-α gene expression by these cells when cultured on the polished discs, while increased expression of HBD3 was detected for all groups in the presence of LPS. Modification of titanium discs by NaOH at 60°C or 120°C promoted an increase in adhesion and metabolism of osteoblasts and favored the response to inflammatory stimulus.

Published: October 2024

Abstract The present study aimed to assess the tooth discoloration induced by endodontic sealers and establish a correlation between their distinct chemical compositions and this aesthetic concern. Five electronic databases and grey literature were systematically screened to identify studies comparing the tooth discoloration potential of endodontic sealers with different chemical bases. Studies that did not evaluate human teeth or did not employ spectrophotometry as a method for color measurement were excluded. The risk of bias in the included studies was assessed using a modified version of the JBI Critical Appraisal Checklist for Experimental Studies. Data were grouped according to the chemical composition of the sealers and analyzed qualitatively. Fourteen studies were included. None of the studies met all domains of the risk of bias checklist. Qualitative synthesis suggested that zinc oxide and eugenol-based sealers have a greater potential for tooth discoloration. Silicone-based and calcium hydroxide-based sealers demonstrated less potential for tooth discoloration than resin-based sealers and salicylate resin-based sealers containing calcium silicate. All investigated endodontic sealers induced tooth discoloration, which is chemical and time dependent. Zinc oxide and eugenol-based sealers exhibited a greater potential for tooth discoloration, whereas silicone and calcium hydroxide-based sealers showed less potential.

Abstract Teaching requires the incorporation of communication skills, and these potentials may affect the outcomes of the learning process. This study evaluated the quality of communication between professors and students during the process of learning Dentistry. A questionnaire was developed and applied to evaluate their perceptions about their communications in an undergraduate Dentistry course. The questionnaire had ten items to analyze professors’ self-perception and ten for students’ perceptions, using a Likert-like scale and a final open question. During its construction, it was sent to five specialists to analyze content validity. The open question gathered suggestions to improve and intensify communications effectively and to identify vulnerabilities. Total scores ranged from 10 to 50, with 10 as the worst perception, and 50, as the best. The scores were calculated by adding all answers and then dividing that sum by the total number of items. Cronbach’s alpha was calculated to evaluate the instrument’s internal consistency. The level of significance was set at 0.05%. The Student t-test was used to determine differences between groups. Professors’ self-perceptions and students' perceptions of the quality of communication of the university teaching staff during the student's learning process had statistically significant differences. Professors classified their ability to communicate when emitting and receiving information as satisfactory. Students, however, did not fully agree with them, particularly on the items about receiving information. The perceptions identified in this study may lead to a new direction in the communicative behavior of professors and students.

ABSTRACT: There are few studies on the extraction of bioactive compounds from olive pomace by the microwave method of hydro diffusion and gravity (MHG). Therefore, this study extracted bioactive compounds from pomace by MHG using a central rotational compound (DCCR). The statistical model showed a significant difference for the variable potency (W) in the extractions of phenolic compounds, showing linear behavior. Simple linear regression analysis suggested the use of 100W of power for the extraction of phenolic compounds in olive pomace. There were no significant differences in flavonoid extractions and antioxidant capacity of the extracts, at different potencies (W) and times (min), in the olive pomace extracts.

ABSTRACT: The study was conducted on a 3-year-old female Santa Inês sheep from a property located in the municipality of Santo Antônio de Tauá, west of Pará. The affected animal had a history of exophthalmos in the left eye, nasal discharge, and breathing difficulty for more than three months. On physical examination, the animal had a low body score, apathy, unilateral facial asymmetry, moderate unilateral left exophthalmos, mixed dyspnea and unilateral profuse serosanguinous nasal discharge. At necropsy, a large nasal mass was observed, predominantly yellowish-white with blackish-red areas, with an irregular, finely granular, moist, and friable surface. The mass invaded from the mucocutaneous junction of the left nostril to the choanae, infiltrated the frontal sinuses, the cribiform plate, and reached the meninges and the frontal portion of the brain. Microscopy of the surface of the nasal epithelium showed severe destruction of the turbinates and epithelia, evidenced by extensive areas of necrosis with a large amount of cellular debris, ulceration, and secondary bacterial infection. In the central nervous system there was pyogranulomatous meningitis with marked vessel congestion, as well as foci of necrosis and granulomatous inflammation. Immunohistochemistry showed intense staining of numerous intralesional hyphae for antibodies against Conidiobolus lamprauges. The diagnosis of granulomatous rhinitis of mycotic origin associated with the Conidiobolus lamprauges was based on epidemiological, clinical-pathological, and immunohistochemical data.

ABSTRACT Objective: To establish the epidemiological profile of shoulder injuries suffered by surfers, through the injury proportion rate, type, mechanism and/or severity, caused by surfing. Methods: This systematic review was conducted and written in accordance with the guidelines for systematic reviews– PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). The bibliographic research was carried out between January 2020 and January 2022 in journals indexed in the Web of Science, SPORTDiscus, PubMed, Scopus, Cochrane and Embase databases. Data were analyzed in RStudio, and the methodological quality of the studies was assessed. Results: Ten studies were included, all of which were retrospective in cross-sectional design and had an average methodological quality of 75%. The meta-analysis showed an injury incidence rate of 14.88%. Odds ratio analysis showed that injuries of joint origin are 7.26 times significantly higher in individuals with shoulder injuries, and injuries of bone origin and skin injuries had reduced odds of 70% and 89%, respectively. The most common mechanism of injury was the movement of paddling (57,68%), with the average prevalence of acute injuries being 31.53% and chronic injuries being 68.47%. Conclusion: There was a scarcity and/or variation in the categorization of data regarding injuries in the shoulder region resulting from surfing, with injuries of joint and musculotendinous origin being frequent; and rowing, the most overloading factor.

Published: October 2024

A abordagem do conteúdo de óptica geométrica costuma ser desafiadora para os professores do ensino médio e superior, pois, além da complexidade do assunto, eles enfrentam dificuldades para a demonstração dos fenômenos ópticos, devido às limitações experimentais encontradas. Neste contexto, o presente trabalho abordou o conteúdo de lentes esféricas por meio da construção e do estudo de duas lentes biconvexas simples, uma espessa de formato esférico (lente-bola), feita com balões de fundo chato, e outra com foco ajustável, cuja superfície foi produzida com látex, ambas utilizando água como meio de propagação. O objetivo do trabalho foi analisar o comportamento da luz ao incidir nas lentes e explorar seus pontos notáveis, como a distância focal, a formação de imagens e a relação entre as distâncias do objeto e da imagem. A partir dos resultados encontrados, verificou-se que o comportamento das lentes produzidas está de acordo com os princípios teóricos da óptica geométrica. Imagens reais e invertidas foram obtidas de acordo com a literatura e a relação entre as distâncias do objeto e da imagem à lente foi verificada. Dessa forma, conclui-se que as lentes construídas com materiais de fácil acesso podem ser ferramentas eficazes para o ensino de óptica geométrica, permitindo a investigação experimental de conceitos importantes desse ramo da física e a simulação de sistemas ópticos reais.
Rural poverty, network ties and institutional forces: an analysis of empirical evidence in Aguascalientes, Mexico
Authors: Parga-Montoya Neftali , Cuevas-Vargas Héctor
Published: October 2024

Abstract The research objectives are: 1) to determine the effects that knowledge, educational and socio-cultural capabilities have on poverty reduction; 2) to determine the effects that collaborative networks have on knowledge, educational and socio-cultural capacities; and 3) to determine the effects of legal protection and government support on collaborative networks. The capability approach was taken as a theoretical basis to develop the study variables. We conducted an empirical study, using a sample of 95 farmers located in the state of Aguascalientes, Mexico. Important implications were obtained on the necessity to have network ties to impact capabilities that reduce rural poverty. One of the most important findings was not finding empirical evidence on the relationship between educational capabilities and the reduction of rural poverty. For this reason, this situation must be reviewed in-depth by the educational policy of the region. Farmers who reported having better socio-cultural capacities had the greatest effects in reducing poverty within their rural communities. Similarly, collaborative networks favor knowledge capacities because important information is shared through social and economic actors.

Resumo O presente artigo teve como objetivo compreender como a adoção de estrutura de governança pode influenciar nos recursos e capacidades na produção rural para inserção e continuidade de pequenos produtores na cadeia de valor do café especial no Paraná. Para tanto, utilizou-se como aporte teórico a Economia dos Custos de Transação (ECT) e a Visão Baseada em Recursos (VBR), em conjunto. Realizou-se uma pesquisa qualitativa e descritiva com produtores de cafés do Paraná e uma empresa exportadora de cafés especiais. Como resultados, para as transações de cafés especiais, identificou-se que a estrutura de governança híbrida, pautada em relações de longo prazo, fornece subsídios para o desenvolvimento e aprimoramento de recursos e capacidades estratégicos e específicos à transação. Observou-se também que a estrutura de governança híbrida viabiliza a combinação para potencializar esses recursos e capacidades, de maneira que eles se tornem mais estratégicos, podendo gerar vantagem competitiva. Portanto, é por meio da estrutura de governança híbrida que é possível alavancar os recursos e capacidades, inclusive de maneira estratégica, para inserção e continuidade dos pequenos produtores em cadeias de maior valor agregado, como a de cafés especiais.

Published: October 2024

Resumo O artigo tem como objetivo verificar se há hiperconcentração de gastos no final do ano fiscal no Ministério da Agricultura, Pecuária e Abastecimento (MAPA) e discutir quais impactos potenciais desse fenômeno para a qualidade do gasto no campo das políticas públicas de agricultura. No primeiro momento, calculou-se o gasto médio mensal de todos os convênios celebrados pelo MAPA entre 2010-2023, dividindo-os pelo nível de gasto mensal médio anual, e, no segundo, conduziu-se entrevistas com gestores públicos federais. Os resultados apontam que, embora não haja uma hiperconcentração generalizada de gastos no final do ano fiscal, há uma concentração significativa de convênios celebrados. A análise qualitativa destacou obstáculos processuais como contingenciamento de gastos, influência política partidária no processo de celebração dos convênios, além de pressões institucionais para celebração em dezembro, com vistas a não perder o recurso no final do ano fiscal. Conclui-se que os incentivos oferecidos aos gestores públicos federais são voltados à execução do orçamento a qualquer custo, visando não penalizar o órgão no ano seguinte, e que esse tipo de arranjo não contribui para um ambiente que privilegia decisões baseadas em evidências e, por conseguinte, à melhoria na qualidade do gasto público.
Effect of seeding speed and graphite lubricant on soybean plantability
Authors: Mota Marcelo C. , Lima Oséias N. de
Published: October 2024

ABSTRACT This study aimed to assess the efficiency of soybean seed distribution in the soil, which directly influences crop yield, using graphite as a solid lubricant, a common practice to improve seed dosing fluidity. The effect of sowing speed and seed chemical treatment on distribution in the furrow, final plant population, and yield was investigated. The experiment used Federer´s augmented block design with 10 treatments, five sowing speeds (4, 6, 8, 10, and 12 km h-1) and two seed treatments (with and without 4 g of graphite lubricant per kilogram of seeds). High sowing speeds increased uneven seed distribution, while graphite lubricant significantly improved plant spacing and crop yield. This study reinforces the importance of precise sowing speed adjustment and proper seed treatment to optimize soybean plant distribution in the field. Graphite lubricant proved to be effective at reducing spacing failures and increasing crop yield. These findings underscore the relevance of precision agriculture and the use of technology to ensure efficient and sustainable sowing operations.

ABSTRACT Santa Catarina is a significant banana producer, responsible for 722 tons annually. For every 1,000 kg of bananas harvested, approximately 3,000 kg of pseudostem, 650 kg of peels, and 350 kg of rejected fruit are generated. Studies have evaluated the use of banana residues for bioethanol production. Solid residues like banana pseudostem bagasse, banana peels, and vinasse (fermented broth residue) are produced during this process. This study aimed to quantify and characterize these residues for biogas and methane production. Banana peels and vinasse were more suitable for containing lower total solids content and favorable C:N (carbon:nitrogen) ratios (10-30:1), yielding higher biochemical potential of methane (260 mLCH4 gvs -1) compared to banana pseudostem bagasse (201 mLCH4 gvs -1). However, vinasse had a high hydrogen sulfide content (0.0783%), necessitating desulphurization for safe biogas use. The results indicate that banana pseudostem bagasse, banana peels, and vinasse have substantial potential for biogas and methane production due to their high degradation rates. The biogas composition meets the criteria for use, with adequate methane and carbon dioxide concentrations, highlighting the viability of these residues for energy generation and contributing to sustainability in banana cultivation.

ABSTRACT The field capacity of Oxisol was evaluated using the flux density in the field, Arya-Paris model, and Richards pressure chamber with non-deformed samples, and the water retention curve and soil moisture were determined using the Arya-Paris model at a pressure of 10 kPa. The research was conducted at the Federal University of Rondonópolis, Mato Grosso state, Brazil. The soil evaluated was Oxisol at depths of 0-10 and 10-20 cm. Using the flux density method, at a water flux density q = 0.10 mm per day and 1.0 mm per day, soil moisture values at field capacity were 0.30 and 0.32 m3 m-3, respectively, at a depth of 0-10 cm and 0.28 and 0.31 m3 m-3, respectively, at a depth of 10-20 cm. Comparing the results obtained with the pressure chamber with those of the field capacity obtained for q = 0.1 mm per day, the mean absolute error and bias were 0.880 and -0.218, respectively, for the 0-10 cm depth and 2.57 and -2.57, respectively, for the 10-20 cm depth. Field capacity of Oxisol can be obtained by subjecting undeformed 50 cm3 samples to a pressure of 10 kPa. The Arya-Paris model is an alternative for determining the soil water retention curve and the field capacity of Oxisol.

Abstract Introduction The control of peri-implant biofilm plays a crucial role in the long-term success of dental implants. Topical treatment alternatives aimed at reducing or preventing biofilm accumulation around the implant's prosthetic components are critical for the success of the treatment. Objective The present study has clinically evaluated the effects of an oxygen-releasing mouthwash (BlueM®) over a 90-day period, following implant placement surgery. Material and method Inclusion and exclusion criteria allowed for the selection of participants who, after implant placement, were randomized into two groups: the control group, which used a 0.12% chlorhexidine mouthwash, and the BlueM group, which received the oxygen-releasing BlueM mouthwash. All participants were instructed to rinse twice daily for the first 10 days and once a day up to 30 days post-surgery. Clinical parameters were evaluated, including the visible plaque index (VP), marginal bleeding (MB), presence of calculus (PC), suppuration (SUP), mucositis (MU), and the extent of keratinized gingiva (KG). These data were collected at the time of suture removal (baseline). At 90 days postoperative, in addition to the aforementioned parameters, probing depth (PD), bleeding on probing (BOP), and the presence of peri-implantitis (PI) were evaluated. Result Nine patients were included in this study, with a total of 38 implants. The BlueM group demonstrated a reduction in MB and an even greater reduction in VP. The other assessed parameters showed similar results to those in the control group. Conclusion BlueM mouthwash has clinical benefits for biofilm control and gingival inflammation reduction.
