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.

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.

Assessing the dynamics of pollutants in the environment is a very complex challenge, primarily because of the large number of variables involved. Thus, in addition to processes that depend on the physicochemical properties of the pollutant and the main characteristics of the contaminated environment, there are less obvious phenomena that also influence the dynamics of pollutants, such as colloid-mediated transport. The objective of this work is to elucidate the main characteristics of this process and its influence on the transport of pollutants through the soil, taking glyphosate as an example. Although this pollutant is strongly retained by soil components, its presence in groundwater is quite frequent, often due to this facilitated transport by colloids. challenge involved Thus colloidmediated colloid mediated example components frequent colloids

ABSTRACT Due to the importance of grain production, and the need to work the soil under limited moisture, the aim of this study was to develop computer software to predict the tractive capacity of wheeled tractors for two types of tyre, the effect of different inflation pressures and levels of soil moisture. A mathematical model was developed to predict the tractive capacity of a 4 x 2 AFT tractor. Software was developed and tested by comparing the computational data with those from tests of a working tractor in the field. The parameters under evaluation were drawbar force and front and rear drive wheel slip. At both moisture levels, the bias tyres had the lowest front to rear slip ratio at the lower pressure; the ratios were similar when equipped with radial tyres. The bias tyres show maximum force at a slip ratio of 1.09 at the higher pressure and 1.03 at the lower, while for the radial tyres the ratio was 1.05 at the higher pressure and 1.07 at the lower. Software was developed to process data from the model, with the results used for estimating the tractive force of the tractor. The tractive force was overestimated by the model, which needs further adjustment for direct application in the field. production tyre field 109 1 09 1.0 103 03 105 05 107 07 10 0 1.

RESUMO: O objetivo deste trabalho foi extrair lignina de Eucalyptus sp. licor negro kraft e avaliar a influência de sua adição nas propriedades do adesivo lignina-fenol-formaldeído. Os adesivos foram sintetizados em diferentes porcentagens de massa de fenol por lignina, denominados adesivos lignina-fenol-formaldeído nas proporções de 25, 30, 50, 75 e 80%. Os parâmetros avaliados nos adesivos foram pH, teor de sólidos totais, teor de compostos orgânicos, teor de compostos inorgânicos, tempo de gelatinização e comportamento do adesivo na linha de cola. O pH variou de 10,63 a 11,65. Para o teor de sólidos totais foi encontrado o valor de 53 a 69%. Os teores de compostos orgânicos variaram de 51 a 75% e de inorgânicos de 25 a 49%. Observou-se que com a adição da macromolécula na formulação do adesivo, o teor de sólidos totais e orgânicos foi reduzido proporcionalmente enquanto o de sólidos inorgânicos foi elevado. O tempo de gelatinização foi reduzido devido à adição de lignina. As menores proporções de adição apresentaram melhor penetração e fluidez na interface com a madeira. A lignina kraft extraída do licor negro kraft de eucalipto é um ótimo adesivo com potencial para substituir parcialmente o fenol derivado do petróleo, com grande potencial para uso e aplicação nos setores aeronáutico e automotivo, no processo de colagem de peças estruturais.

ABSTRACT: The objective of this research was to extract lignin from Eucalyptus sp. kraft black liquor and to evaluate the influence of its addition on the properties of the lignin-phenol-formaldehyde adhesive. The adhesives were synthesized at different phenol mass percentages by lignin, called lignin-phenol-formaldehyde adhesives in the proportions of 25, 30, 50, 75 and 80%. The parameters evaluated in the adhesives were pH, total solid content, organic compound content, inorganic compound content, gelatinization time and adhesive behavior in the glue line. The pH ranged from 10.63 to 11.65. For the total solid content was found the value of 53 to 69 %. The contents of organic compounds ranged from 51 to 75% and inorganic from 25 to 49%. It was observed that with the addition of macromolecule in the adhesive formulation, the total and organic solid content was reduced proportionally while the inorganic solid was high. The gelatinization time was reduced due to the addition of lignin. The lower proportions of addition presented better penetration and fluidity in interface with the wood. The kraft lignin extracted from eucalyptus kraft black liquor is a great adhesive with potential to partially replace petroleum-derived phenol, with great potential for use and application in the aeronautical and automotive sectors, in the bonding process of structural parts.

BiOCl/KBiO3 p-n heterostructures with hierarchical mesoporous architectures were successfully synthesized via a facile in situ method. The X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM) results indicate the formation of heterojunctions between BiOCl and KBiO3. The photocatalytic performance of the as-prepared samples was investigated by the degradation of dye Rhodamine B (RhB) under visible light irradiation. BiOCl/KBiO3 composite has never been used to photodegrade the RhB which is a common dye and very difficult to degrade. The results demonstrated that KBiO3 combined with proper amount of BiOCl nanosheets exhibited high efficiency in the photocatalytic process, and BiOCl/KBiO3 with the molar ratio of 70/30 demonstrated the highest photocatalytic activity due to its large surface area, excellent charge separation characteristics and the suppressed recombination of electron-hole pairs. The results of active species detection reveal that the superoxide radical anions (O2-), hydroxyl free radicals (·OH), photogenerated holes (h+) and photogenerated electrons (e-) reactive species work together for the photocatalytic degradation of RhB. A possible and new mechanism of photocatalysis that differs from other teams was also explored and proposed. The present study will benefit the development of the new p-n heterojunction photocatalysts and would be of great importance to meet ever-increasing environmental demands in the future.

Novel nanocomposites synthesized with pollen grain, as a precursor, were tested for CO2 adsorption performance. The pollen-derived carbons were obtained by direct calcination (PC), calcination followed by KOH-chemical activation (PCKOH), and MgO incorporation using high-energy ball-milling (PC-MgO and PCKOH-MgO). All the as-prepared materials were texturally, morphologically and structurally characterized by N2 physisorption, scanning electron microscopy (SEM-EDS) and X-ray diffraction (XRD); CO2 adsorption/desorption was measured by thermogravimetry. The four materials were able to adsorb CO2 at 30 ºC and 1 bar, but PCKOH-MgO, with the high surface area (12.4 m2 g-1), total pore volume of (0.13 cm3 g-1) and microporosity, was the best (2.06 mmol g-1 and percentage of adsorption (Qad) = 9.06%, at 1 bar). This result is due to the synergic effect of both synthesis methods. Neither temperature (from 30 to 100 ºC), nor pressure (from 1 to 15 bar), improved the adsorption process of PCKOH-MgO. CO2 desorption times at 300 ºC were 47 min for PCKOH-MgO and 30 min for the other adsorbents, showing the possibility of cycling. Based on the obtained results, the PCKOH-MgO activated carbon nanocomposite stands as a promising adsorbent to be potentially used for industrial CO2 capture applications and to contribute to long-term solutions to avoid dangerous climate-change and reduce CO2 emissions. grain precursor CO performance pollenderived derived PC, PC , (PC) KOHchemical KOH chemical PCKOH, PCKOH (PCKOH) highenergy energy ballmilling ball milling PCMgO PCKOHMgO.

ABSTRACT Desertification is the degradation process caused by climatic conditions and human activities that results in loss of soil productivity and decline in vegetation growth in the long term. Several indices related to vegetation, soil and climate are used to monitor desertification, but few studies explore qualitative and quantitative aspects of indices on desertification on spatial and hierarchical scale. This study aims to identify and measure indices related to increased risk of desertification on global, local and hierarchical scales using multinomial logistic regression models. Images from TM, ETM+ and OLI sensor from 1997 to 2018 in the end of dry and rainy seasons were used to quantify NDVI, TGSI, albedo, temperature, aridity index, evapotranspiration and precipitation on global spatial scale (Irauçuba Centro Norte) and local spatial scale (Miraíma, Canindé, Irauçuba and Santa Quitéria). GISD was calculated by geometric mean of weighted indices and segmented into 8 classes of susceptibility to desertification (hierarchical scale). The results showed that the best models were obtained on local scale and for the end of the rainy season. Temperature proved to be the most important variable for increased risk of desertification on global, local and hierarchical scales. Therefore, the increase in the risk of desertification in the studied areas is due to human activities of deforestation, overgrazing and fire. These factors contributed to reduction of vegetation cover and increase in temperature, changing the microclimatic, which led to decline in precipitation and worsening of desertification. term TM ETM 199 201 NDVI TGSI albedo temperature index Norte Miraíma, Miraíma (Miraíma Canindé Quitéria.

Microparticulated whey protein can be used as a fat substitute in foods to enhance their nutritional value and improve their sensory and rheological characteristics. Microparticulation denatures whey proteins through heat treatment, followed by shear rate control to determine the aggregate sizes formed. The processing method used during microparticulation can modify the protein denaturation rate, which may enable the application of new proteins. This study sought to develop a methodology for quantifying whey protein fractions in commercial samples before and after microparticulation at different concentrations and physical states. The developed methodology proved to be applicable because of its selectivity, quantification, detection limits, and precision. The analyzed samples exhibited a higher denaturation rate for β-lactoglobulin than α-lactoalbumin; the denaturation rate varied among samples due to differences in the microparticulation process. characteristics treatment formed states selectivity quantification limits precision βlactoglobulin β lactoglobulin αlactoalbumin α lactoalbumin α-lactoalbumin process

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.

In this work, using the PM3 semi-empirical method, the oxidation of the single-walled carbon nanotube (SWCNT) was studied by sulfuric and nitric acid for the incorporation of carbonyl (C=O), phenol (OH) and carboxylic (COOH) groups in the C=C bonds present on the surface of the nanotube. Subsequently, the crosslinking of the oxidized SWCNT (SWCNTox) and chitosan (Q) was observed through hydrogen bonds of the C=O and OH bonds with 2.34 Å, the process was endothermic and soluble in polar solvents due to the presence of OH and NH groups in the structure of SWCNTox/Q. The Monte Carlo modeling allowed to study the adsorption of pesticides in the SWCNTox/Q at different temperatures, where the QSAR (quantitative structure activity relationship) properties allowed predicting the behavior of the pesticides, that is, the degree of hydrophobicity (log P) and accessible surface area (ASA) were important parameters in the evaluation of SWCNTox/Q as an adsorbent and surface interacting with pesticides respectively. Finally, the adsorption was a physisorption process due to the electronegativity of the CO, OH, NH2, NH and C=O bonds. work PM semiempirical semi empirical method singlewalled single walled (SWCNT C=O, CO , C O (C=O) (OH COOH (COOH CC Subsequently SWCNTox (SWCNTox Q (Q 234 2 34 2.3 Å SWCNToxQ temperatures quantitative relationship is log P ASA (ASA respectively Finally NH2 (C=O 23 3 2.

RESUMO Santa Catarina é um importante produtor de banana, responsável por 722 toneladas anuais. Para cada 1.000 kg de banana colhida, são gerados aproximadamente 3.000 kg de pseudocaule, 650 kg de cascas e 350 kg de frutos rejeitados. Estudos avaliaram a utilização de resíduos de banana para produção de bioetanol. Resíduos sólidos como bagaço de pseudocaule de banana, cascas de banana e vinhaça (resíduo de caldo fermentado) são produzidos nesse processo. Este estudo teve como objetivo quantificar e caracterizar esses resíduos para produção de biogás e metano. Cascas de banana e vinhaça foram melhores por conterem menor teor de sólidos totais e relações C:N (carbono:nitrogênio) favoráveis (10 - 30:1), proporcionando maior potencial bioquímico de metano (260 mLCH4 gvs -1) em comparação ao pseudocaule de bananeira bagaço (201 mLCH4 gvs -1). No entanto, a vinhaça apresentou alto teor de sulfeto de hidrogênio (0,0783%), necessitando de dessulfurização do biogás gerado para seu uso seguro. No geral, os resultados indicam que o bagaço do pseudocaule da banana, as cascas de banana e a vinhaça têm potencial substancial para a produção de biogás e metano devido às suas altas taxas de degradação. A composição do biogás atende aos critérios de utilização, com concentrações adequadas de metano e dióxido de carbono, destacando a viabilidade desses resíduos para geração de energia e contribuindo para a sustentabilidade no cultivo da banana. 72 anuais 1000 1 000 1.00 colhida 3000 3 3.00 65 35 rejeitados bioetanol resíduo fermentado processo CN C N carbononitrogênio carbono nitrogênio (carbono:nitrogênio 10 (1 301, 301 30 , 30:1) 260 (26 mLCH -1 201 (20 1. . entanto 0,0783%, 00783 0,0783% 0 0783 (0,0783%) seguro geral degradação 7 100 00 1.0 300 3.0 6 ( 30:1 26 (2 20 0078 0,0783 078 (0,0783% 3. 30: 2 007 0,078 07 (0,0783 0,07 (0,078 0,0 (0,07 0, (0,0 (0, (0

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. producer 72 annually 1000 1 000 1,00 harvested 3000 3 3,00 65 35 generated fermented residue process CN C N carbonnitrogen nitrogen (carbon:nitrogen 10301, 10301 10 30 , (10-30:1) 260 (26 mLCH -1 201 (20 1. .

Abstract This paper analyzes the stigma managing in sex work, arguing that this process is based on a longing for recognition and not merely on expectations to validate and normalize the dirty work. It uses contemporary sociological debates about dirty works, which aim to understand the impact of moral taints on workers and the strategies for stigma management. The analysis is developed in webcamming sex labor, a central locus to understand demands for recognition due to the breadth of its taint. The study relies on digital ethnography conducted between 2016 and 2020 and on 15 in-depth interviews with sex workers. The paper concludes that workers aim to develop a positive self-relation and acquire social esteem by managing the stigma attributed to their work and to themselves, demonstrating narratively how sex labor contributes to their self-development and has a social role besides earning income. works management taint 201 202 1 indepth depth selfrelation self relation themselves selfdevelopment development income 20 2

Abstract Self-healing consists of closing cracks and recovering the watertight properties of cement-based materials and can occur by hydration of the materials of the mixture (autogenous) or by materials added to the mixture for this purpose (autonomous). This study consists of the use of stimulated self-healing as a way of mitigating sulfate attack (sodium and magnesium), with the evaluation of the influence of crystalline admixture in this process. For that, cycles of sulfate attack and self-healing (by wetting and drying cycles in water) were performed, aiming to evaluate the behavior of mortars with three types of cement: Portland, supersulfated, and alkali-activated. The results showed that self-healing was not sufficient to close cracks due to sulfate attack. This behavior was associated with the hypothesis that the high calcium content of the crystalline admixture reacted with the sulfates and formed expansive products, increasing the attack rate.

Resumo A autocicatrização consiste no fechamento de fissuras e recuperação da estanqueidade dos materiais à base de cimento e pode ocorrer por hidratação dos materiais da mistura (autógena) ou por materiais adicionados à mistura para esse fim (autônoma). Este estudo consiste na utilização de autocicatrização autógena estimulada como forma de atenuar o ataque por sulfatos (sódio e magnésio), com a avaliação da influência de adição cristalizante neste processo. Para isso, foram realizados ciclos de ataque sulfatado e autocicatrização (ciclos de molhagem e secagem), com o objetivo de avaliar o comportamento de argamassas com três tipos de cimento: Portland, supersulfatado e álcali ativado. Os resultados mostraram que a autocicatrização não foi suficiente para fechar trincas devido ao ataque por sulfatos. Esse comportamento foi associado à hipótese de que o alto teor de cálcio da adição cristalizante reagiu com os sulfatos e formou produtos expansivos, aumentando a taxa de ataque.

Abstract Introduction: Almost 800 female deaths occur daily due to preventable causes associated with complications during or after pregnancy or childbirth, equivalent to two maternal deaths per minute. Objective: To develop a nursing care process for a pregnant woman who suffered from hyperthyroidism using diagnostic taxonomies, results and nursing interventions with a focus on Orem's theory. Methodology: Case study of a pregnant woman treated in a second level care hospital, the Orem assessment guide was used, developing the stages: assessment, diagnosis, planning, execution and evaluation, individualized care plans were designed and executed. Privacy was protected by omitting identity, respecting the rights and well-being of the participant. Results: The risk conditioning factor that compromised the health of the mother-child binomial gave way to care planning aimed at the process of ineffective motherhood and ineffective self-management of health, establishing interventions such as high-risk pregnancy care and teaching the process of illness and prescribed medications, an improvement was obtained in the patient's health status, which allowed her discharge and adequate management of the high-risk pregnancy. Conclusion: The nursing care process exposed the context in which the pregnant woman with known uncontrolled pathology is admitted, which compromised maternal-fetal well-being. Nursing education is required to promote preconception maternal health for future pregnancies.
