Abstract (Introduction): Vinasse is generated as a residue in the production of ethanol by fermentation-distillation of molasses/sugar cane juice, at a rate of 13 L/L of ethanol. It is an acid liquid, brown in color, characterized by high mineralization and Chemical Oxygen Demand (COD) values of up to 150 000 mg/L, being highly polluting. (Objective): The objective of this research was to evaluate a vinasse treatment process with hydrogen peroxide as a source of hydroxyl radicals at laboratory scale. (Methodology): The vinasse samples, from different distilleries in the province of Tucumán, were characterized following standardized techniques of Standard Methods. The oxidation tests were carried out with different peroxide/vinasses ratios, in a semi-batch reactor, under ambient conditions, measuring COD as an indicator parameter of the treatment. (Results): After 5 days, an 85 % decrease in COD and an increase in the Biodegradability Index were achieved. The kinetics of the oxidative reaction was first order with respect to COD, with an apparent rate constant of 0.3694 1/day. (Conclusions): Although the COD values allowed by local regulations (250 mg/L) were not reached, the proposed treatment is encouraging due to its simplicity, representing a potential option to the environmental challenge represented by vinaze in Latin America.

Resumen (Introducción): La vinaza se genera como residuo en la producción de etanol por fermentación-destilación de melazas/jugos de caña de azúcar, a razón de 13 L/L de etanol. Es un efluente líquido, ácido caracterizado por una elevada mineralización y valores de demanda química de oxígeno (DQO) de hasta 150 000 mg/L, siendo altamente contaminante. (Objetivo): Ealuar un proceso de tratamiento de vinazas con peróxido de hidrógeno, como fuente de radicales hidroxilos, en escala laboratorio. (Metodología): Las muestras de vinazas, de destilerías de la provincia de Tucumán, se caracterizaron según técnicas normalizadas de Standard Methods. Los ensayos de oxidación se realizaron con distintas relaciones de peróxido/vinaza, en un reactor semibatch, en condiciones ambientales, midiendo DQO como parámetro indicador del tratamiento. (Resultados): Al cabo de cinco días se logró una disminución de DQO del 85 % y un aumento del Índice de Biodegradabilidad. La cinética de la reacción oxidativa fue de primer orden respecto de DQO, con una constante aparente de velocidad de 0.3694 1/día. (Conclusiones): Si bien no se lograron los valores de DQO permitidos por la normativa local (250 mg/L), el tratamiento propuesto es alentador por su simpleza, representando una opción potencial al desafío ambiental que representan las vinazas en América Latina.

Abstract The critical importance of wetland ecosystems is highlighted, as they provide essential services such as regulating the hydrological cycle, flood control, and filtering pollutants. Globally, 64 % of wetlands have been lost since 1970, with Asia being the most affected region. Agricultural expansion, urban development, and aquaculture are some of the main drivers of the degradation of these ecosystems, particularly mangroves, which play a key role in climate change mitigation. In Costa Rica, wetlands under inventory represent 6.01 % of the national territory, and although the country has made progress in their protection, with 49 % of wetlands falling under some category of protected wild area, challenges remain, such as agricultural expansion, livestock farming, and sedimentation. At the international level, the Ramsar Convention has been key to wetland conservation efforts, with over 2.57 million km2 protected. However, additional efforts are needed to mitigate the threats to these ecosystems, especially in the context of climate change.

Resumen Se resalta la importancia crítica de los ecosistemas de humedales, que proporcionan servicios esenciales, como la regulación del ciclo hidrológico, el control de inundaciones y la filtración de contaminantes. En el nivel global, se ha perdido un 64 % de los humedales desde 1970, con Asia siendo la región más afectada. La expansión agrícola, el desarrollo urbano y la acuicultura son algunas de las principales causas de la degradación de estos ecosistemas, especialmente de los manglares, que cumplen una función clave en la mitigación del cambio climático. En Costa Rica, los humedales bajo inventario representan el 6.01 % del territorio nacional, y aunque el país ha avanzado en su protección, con el 49 % de los humedales bajo alguna categoría de área silvestre protegida, persisten desafíos, como la expansión agrícola, la ganadería y la sedimentación. En el plano mundial, la Convención Ramsar ha sido clave en los esfuerzos de conservación de humedales, con más de 2.57 millones km2 protegidos. Sin embargo, se necesitan esfuerzos adicionales para mitigar las amenazas a estos ecosistemas, especialmente en el contexto del cambio climático.

This article discusses guidance published on official websites regarding the response of the Brazilian National Health System (SUS) psychosocial care networks (RAPS) to the public health emergency caused by Covid-19. The discussion draws on the analysis of online materials published between 06/02/20 and 31/08/21 at state and federal level across all the country’s state capitals. We compare the results of the document analysis with guidance published by international organizations to reflect on the challenges, successes, mistakes and omissions in the guidance given to the RAPS at the beginning of the pandemic. It is concluded that, despite being formal, the guidance was poorly coordinated and integrated into the networks and with other sectors and pre-existing challenges, as recommended by the international community.

The present work focused on the screening process of different inorganic oxides and different temperatures for the epoxidation reaction of macaw palm vegetable oil without using solvent, a promising Brazilian biomass that can substitute other vegetable oils (e.g., soybean oil) in technological applications. This oil has an iodine value of 108.48 g of I2 per 100 g being categorized as a semi-dry oil. The epoxidized vegetable oil can be applied in manifold areas in polymer science. The epoxidation reaction here presented avoided organic solvents and organic acids and aimed to produce a greener route using metal oxides or niobium phosphate as a peroxide-activating catalyst. The experimental parameters were maintained as 10 mol% of catalyst loading and a time of 24 h; however, the temperature for some catalysts was changed to improve the epoxide conversion. Experiments were measured by proton nuclear magnetic resonance (1H NMR). Experiments using titanium oxide (TiO2) as a catalyst reached a conversion greater than 84.7%, while experiments using aluminium oxide (Al2O3) or lanthanum oxide (La2O3) achieved conversions of 22.6 and 30.1%, respectively. Furthermore, it was observed that both niobium compounds instantly react with hydrogen peroxide to form peroxy derivatives. solvent e.g., eg e (e.g. applications 10848 108 48 108.4 I semidry semi dry science peroxideactivating activating 1 mol 2 h however 1H H NMR.

RESUMO: A leptospirose é uma doença zoonótica que deve ser estudada sob o ponto de vista da Saúde Única. É possível que existam particularidades na epidemiologia da leptospirose no bioma Caatinga, onde o ambiente é muitas vezes desfavorável e desafia a adaptabilidade de Leptospira spp. No total, 100 cães (47 de abrigos e 53 errantes) selecionados com base em cálculo amostral foram utilizados para avaliar a soroprevalência de Leptospira spp. e os fatores associados. O teste de soroaglutinação microscópica (SAM) foi aplicado para detetar anticorpos anti-Leptospira spp. (título 50 como ponto de corte). Os fatores de risco foram identificados utilizando a análise de regressão de Poisson robusta. Vinte e quatro animais (24%; IC 95% = 15,6% - 32,4%) foram soropositivos, os títulos de anticorpos variaram de 50 a 200, e os serogrupos reagentes foram Ballum (17%), Autumnalis (6%) e Djasiman (1%). Os fatores/categorias associados à seropositividade foram o ambiente onde o animal se encontra/solo (razão de prevalência [RP] = 6,03; IC 95% para RP: 1,86 - 7,69; P < 0,001) e o acesso a água poluída/sim (RP = 3,79; IC 95% para RP: 1,85 - 24,22; P = 0,011). Os resultados sugerem a leptospirose como uma preocupação no contexto da Saúde Única em cães errantes e de abrigos no bioma Caatinga, apesar das condições adversas desse bioma para a sobrevivência de Leptospira spp. no ambiente. Além disso, apesar de serem questões sociais e governamentais, fatores como o ambiente onde o animal fica (solo) e o acesso à água poluída devem ser cuidadosamente analisados e corrigidos para evitar a transmissão de leptospiras para animais e humanos.

ABSTRACT: Leptospirosis is a zoonotic disease that must be studied on the One Health point of view. It is possible that there are particularities in the epidemiology of leptospirosis in Caatinga biome, where the environment is often unfavorable and challenges the adaptability of Leptospira spp. Overall, 100 dogs (47 shelter and 53 stray dogs) selected based on sampling calculation were used to evaluate the Leptospira spp. seroprevalence and associated factors. The microscopic agglutination test (MAT) was applied to detect anti-Leptospira spp. antibodies (cut-off titer 50). Risk factors were identified using the robust Poisson regression analysis. Twenty-four animals (24%; 95% CI = 15.6% - 32.4%) were seroreactive, antibody titers ranged from 50 to 200, and the reacting serogroups were Ballum (17%), Autumnalis (6%) and Djasiman (1%). The factors/categories associated with seropositivity were the environment where the animal stay/soil (prevalence ratio [PR] = 6.03; 95% CI for PR: 1.86 - 7.69; P < 0.001) and access to polluted water/yes (PR = 3.79; 95% CI for PR: 1.85 - 24.22; P = 0.011). The results suggested leptospirosis as a concern in the One Health context in stray and shelter dogs from the Caatinga biome despite the adverse conditions of this biome for the survive of Leptospira spp. on the environment. Moreover, despite being social and government issues, factors such as environment where the animal stay (soil) and access to polluted water must be carefully deemed and corrected to avoid the transmission of leptospires to animals and humans.

The present study analyzed the chemical composition and phytotoxic activity of Artemisia lancea essential oil (EO). Gas chromatography-mass spectrometry (GC-MS) results showed the presence of 55 compounds, representing 82.36% of the entire EO, with eucalyptol (18.7%) being the most abundant constituent. Phytotoxic bioassay results indicated that the EO (concentration ranging from 0.25-5 mg mL−1) inhibited the growth of Amaranthus retroflexus and Setaria viridis. Root length of A. retroflexus and S. viridis were reduced with the increasing concentration of the EO, especially when the EO was applied at 1-5 mg mL−1. When treated with 1-5 mg mL−1 EO, shoot length of A. retroflexus and S. viridis were also significantly suppressed. The half maximal inhibitory concentration (IC50) values for inhibiting root and shoot growth of A. retroflexus by the EO were 0.284 and 0.246 mg mL−1; for S. viridis, the EO showed IC50 values of 0.44 and 0.262 mg mL−1 for root and shoot inhibition, respectively. The most promising findings were observed when A. lancea EO concentration reached 1 mg mL−1 and higher, which completely inhibited seed germination of A. retroflexus and S. viridis. These findings suggest A. lancea EO has potential as an eco-friendly bioherbicide for agricultural weed control. EO. .

The in silico study aimed to suggest phytochemicals from Commiphora leptophloeos leaves essential oil as therapies against coronavirus disease (COVID-19) (or severe acute respiratory syndrome coronavirus 2, SARS-CoV-2). For that, we used molecular docking (MD), absorption, distribution, metabolism, excretion, and toxicity (ADMET) parameters, and pharmacokinetic analysis. MD showed the presence of hydrophobic and hydrogen bonds for nine compounds. β-Selinene and bicyclogermacrene showed the best interaction values with the protein Mpro (ID: 6Y2F) (-5.9) and chimeric receptor complexed with its receptor human ACE2 (ID: 6VW1) (-6.1 and -5.5) proteins, as well as low gastrointestinal and high epithelial absorptions, medium permeability for Caco-2 cells and high epithelial permeability, low oral excretion, and were inhibitors of CYP2C19 and CYP2C9 enzymes. On the other hand, both were not permeable to the blood-brain barrier and inhibitors or substrates for glycoprotein-D, and showed carcinogenic potential, but only β-selinene was considered mutagenic. Although little bioavailable, both presented aspects structurally adequate, being compounds with moderate synthesis difficulty. Therefore, more analyses are necessary to evaluate the mechanism of action and unsatisfactory parameters foreseen in bioinformatic assays. COVID19 COVID 19 (COVID-19 2 SARSCoV2.

ABSTRACT Biochar can promote crop production and soil quality. However, its characteristics depend on the waste used in its production and its effects may vary according to the species being cultivated and the management adopted. The aim of this study was to evaluate the application of biochar from animal waste on soil quality and the agronomic characteristics of the cowpea. An experiment was set up to test three types of biochar (bovine-BB, swine-SB and poultry-BP), with added fertiliser (BBF, SBF and BPF) and two control treatments, including the addition of calcium magnesium oxide (CT) and calcium magnesium oxide with fertiliser (CTF), giving a total of eight treatments with four replications. There was a respective increase of up to 102.94%, 1048%, 1560% and 360.22% in stem diameter, number of pods, number of grains per pod and stem dry matter from adding the biochar. The poultry biochar increased each of the above parameters even with no added fertiliser. There was no difference in basal soil respiration or β-glucosidase enzyme activity, whereas organic carbon (TOC), total nitrogen (TN), microbial carbon and soil labile carbon were greater with biochar. BBF gave the highest TOC content (24.40 g kg-1), while BP and BPF increased TN by around 61%. The application of biochar + fertiliser contributed to an average reduction of 56% in the soil metabolic quotient. Poultry biochar favoured both the agronomic characteristics of the cowpea and soil quality, while bovine biochar showed more marked results with the addition of fertiliser.

RESUMO Objetivo: Identificar e caracterizar a população de casos pediátricos encaminhados para o nosso centro de oxigenoterapia hiperbárica. Métodos: Estudo retrospetivo e observacional, que incluiu doentes pediátricos tratados com oxigenoterapia hiperbárica, de 2006 a 2021, no centro de referência de medicina hiperbárica do norte de Portugal. As variáveis de interesse foram extraídas dos processos clínicos eletrônicos. Resultados: O nosso estudo incluiu 134 casos. Os motivos de encaminhamento mais frequentes foram intoxicação por monóxido de carbono (n=59) e surdez súbita neurossensorial (n=41). Em 75 casos (56%) o tratamento foi iniciado em contexto de urgência. Os sintomas de apresentação à admissão variaram entre os diferentes casos, sendo os mais frequentes cefaleias e náuseas/vômitos. No que diz respeito à intoxicação por monóxido de carbono, as fontes mais comuns foram o aquecedor, lareira/braseiro e caldeira. Com relação aos efeitos adversos, foram identificados um caso de intoxicação por oxigênio e quatro casos de barotrauma do ouvido médio. Conclusões: A causa mais frequente de encaminhamento foi a intoxicação por monóxido de carbono. Todos os pacientes evoluíram favoravelmente e foram registrados poucos efeitos adversos, o que enfatiza a segurança desta terapia. Uma vez que a maioria dos pediatras pode não estar informada sobre os potenciais benefícios da oxigenoterapia hiperbárica, é de extrema importância promovê-los para que esta técnica seja cada vez mais implementada.

ABSTRACT Objective: To identify and characterize the population of Pediatric patients referred to our hyperbaric oxygen therapy center. Methods: Retrospective and observational study, including pediatric patients treated with hyperbaric oxygen therapy, from 2006 to 2021, at the hyperbaric medicine reference center in the north of Portugal. Variables of interest were extracted from electronic medical records. Results: Our study included 134 patients. The most frequent reasons for referral were carbon monoxide poisoning (n=59) and sudden sensorineural hearing loss (n=41). In 75 cases (56%), treatment was initiated in an urgent context. Symptom presentation at Emergency Department varied among patients, the most frequent being headache and nausea/vomiting. Concerning carbon monoxide poisoning, the most common sources were water heater, fireplace/brazier, and boiler. Regarding adverse effects, it was identified one case of intoxication by oxygen and four cases of middle ear barotrauma. Conclusions: The most frequent cause for referral was carbon monoxide poisoning. All patients evolved favorably, with few side effects being reported, emphasizing the safety of this therapy. While most pediatricians may not be aware of the potential benefits arising with hyperbaric oxygen therapy, it is of upmost importance to promote them, so that this technique is increasingly implemented.

Phosphate species can affect aquatic ecosystems, as excess of this nutrient can cause eutrophication, generating environmental impacts. Lamellar double hydroxides have shown promise in removing phosphate at low concentrations (10-50 mg L 1). In this context, lamellar double hydroxides were synthesized interspersed with nitrates and humic substances, searching for a new product that favors phosphorus adsorption. X-ray diffraction showed the presence of characteristic peaks of lamellar double hydroxides and thermogravimetric analysis showed the decomposition behavior of lamellar structure. The adsorption capacity occurred quickly (< 30 min), being more efficient for lamellar double hydroxides with NO3. The maximum adsorption capacity showed results of 35.03 and 44.20 mg g 1 for lamellar double hydroxides with humic substances and lamellar double hydroxides with NO3, respectively. The complexation capacity showed that pH directly influences complexation, being greater for lamellar double hydroxides with humic substances at pH 6.5. Thus, nanostructured materials with humic substances are promising for use in contaminant remediation and adsorption can be a fast and efficient technique for use in soil and water. ecosystems eutrophication impacts 1050 10 50 (10-5 1. . 1) context Xray X ray structure < ( 3 min, min , min) NO3 NO 3503 35 03 35.0 4420 44 20 44.2 respectively 65 6 5 6.5 Thus water 105 (10- 350 0 35. 442 4 2 44. 6.

In the present study a spectrophotometric method for Cr(VI) determination in organic fertilizers, especially those from tanning industry residues, is proposed. Conditions for chromium extraction, extract clean-up and analytical characteristics of the method were established. The method is based on the complexation of Cr(VI) with 1,5-diphenylcarbazide (DPC) in acid medium (pH 2.0). A mixture of NaOH and Na2CO3 solution at 0.125 and 0.07 mol L–1 (pH 12), respectively, and heating at 90 °C for 60 min were the best conditions for chromium extraction. Florisil and activated charcoal were tested for clean-up of the extract, with activated charcoal being effective. Under the established conditions, the calibration linear range is up to 2500 μg L–1 Cr(VI), the results obtained are in agreement with the value of a certified reference material (CRM041), precision is better than 5% for five consecutive determinations of a solution at 1000 μg L–1 of Cr(VI) and the limit of quantification is 1.62 μg g–1. In can be concluded that the method is robust, accurate and precise, and can be easily applied for the determination of Cr(VI) in routine analysis, since it complies with legislation of most countries regarding the maximum allowed concentration of 2 μg g–1 of Cr(VI).

ABSTRACT The correct use of tyres on agricultural tractors, in respect of the terrain and the type and internal pressure of the tyre, are factors that influence the performance of the tractor. The aim of the present study was to evaluate the operating performance of an agricultural tractor fitted with two types of traction device (radial and diagonal tyres) at different pressures, and operating on soil with two levels of moisture. The experiment was conducted on a dystrophic Red Yellow Argisol, with tests to evaluate the performance of the tyres under specific working conditions. Tractive power and tractive force, wheel slip and fuel consumption were evaluated. For each of the conditions under evaluation, the radial configuration showed better performance than the diagonal configuration, the effect being more significant at the lower pressure and under low soil moisture. The use of radial tyres led to an increase in traction capacity and drawbar power, with a reduction in fuel consumption, especially at higher slip rates. tractors tyre pressures moisture Argisol force evaluated evaluation rates

ABSTRACT Cobalt (Co) and molybdenum (Mo) are essential elements with a fundamental role in biological nitrogen fixation in legumes. Vitamins such as thiamine, despite being required in small quantities, influence plant growth. This study aimed to assess the efficiency of different doses of thiamine applied as seed treatment, combined or not with Co and Mo, in enhancing the development of soybean crops. The experiment was conducted in a greenhouse according to a randomized block design with a 6 × 2 factorial arrangement, comprising six thiamine doses (0, 10, 25, 50, 100, and 200 mg kg-1) in the presence or absence of Co and Mo at the recommended rate of 100 mL ha-1. At 40 days after sowing, plants were analyzed for root length, root dry weight, shoot length, shoot dry weight, nodule number, and nodule dry weight. Principal component analysis showed that combined application of Co and Mo with thiamine was negatively associated with all variables and that the thiamine doses most positively associated with the analyzed variables were 50 and 200 mg kg-1. In treatments containing thiamine alone, there was a linear direct relationship between thiamine dose and nodule dry weight. Root and shoot lengths and dry weights were highest in plants treated with thiamine only at a dose of 122 mg kg-1.

Abstract Objective To develop and validate a brief intervention strategy based on the concept of implementation intention to promote adherence to oral antidiabetics in people with type 2 diabetes mellitus being monitored in primary care. Method This is a methodological study carried out in a primary health unit in Carmo do Cajuru, Minas Gerais, Brazil, from May 2022 to April 2023. The stages taken involved intervention construction based on the concept of implementation intention, with validity of its content by seven experts and assessment of its comprehensibility by 11 people with type 2 diabetes mellitus. An expert committee assessed the intervention’s relevance, comprehensibility and comprehensiveness, and the target audience exclusively assessed their comprehensibility through a cognitive interview. Agreement among experts was assessed by the item and total Content Validity Index (CVI), with item and total CVI being considered satisfactory ≥ 0.85. Results The intervention strategy was called “Plan for coping with difficulties in taking oral antidiabetics”, and its final validated version was composed of a set of initial instructions, a topic on intended behavior, a column with 13 possible difficulties and a column with 16 possible solutions to the difficulties listed. A total CVI of 0.99 was obtained, and the intervention strategy was understood by the target audience. Conclusion The brief intervention strategy obtained evidence of content validity. This technology can support and motivate healthcare professionals’ practice, especially nurses, to improve their approach to users with type 2 diabetes mellitus in relation to adherence to oral antidiabetic medications. care Cajuru Gerais Brazil 202 2023 1 interventions s relevance comprehensiveness interview CVI, , (CVI) 085 0 85 0.85 Plan antidiabetics, antidiabetics” instructions behavior listed 099 99 0.9 professionals practice nurses medications 20 (CVI 08 8 0.8 09 9 0.

A presente análise documental tem como objetivo debater as orientações publicadas on-line em sites oficiais para guiar as respostas das Redes de Atenção Psicossocial (Raps) do Sistema Único de Saúde (SUS) do Brasil diante da emergência de Saúde Pública causada pela Covid-19. Baseia-se na análise de materiais publicados on-line entre 6/2/20 e 31/8/21 nos níveis federal e estadual e em todas as capitais do país. Combina essa análise documental com orientações e publicações de entidades internacionais a fim de refletir sobre os desafios, acertos, erros e omissões das orientações dadas para as Raps no país durante o início do período pandêmico. Conclui que as orientações, apesar de existentes formalmente, foram pouco articuladas e integradas dentro das próprias redes, com outros setores e com desafios preexistentes, conforme preconizado pela comunidade internacional. online on line (Raps SUS (SUS Covid19.

This article discusses guidance published on official websites regarding the response of the Brazilian National Health System (SUS) psychosocial care networks (RAPS) to the public health emergency caused by Covid-19. The discussion draws on the analysis of online materials published between 06/02/20 and 31/08/21 at state and federal level across all the country’s state capitals. We compare the results of the document analysis with guidance published by international organizations to reflect on the challenges, successes, mistakes and omissions in the guidance given to the RAPS at the beginning of the pandemic. It is concluded that, despite being formal, the guidance was poorly coordinated and integrated into the networks and with other sectors and pre-existing challenges, as recommended by the international community.
