ABSTRACT Moringa oleifera Lam. is an arboreal forest species of great economic potential, adapted to the climatic conditions of the Brazilian semi-arid region, whose multiplication is mainly by seeds. Rapid viability and vigor tests help in the choice of lots. Thus, the objective of this study was to assess the efficiency of the pH of exudate and primary root protrusion tests in the evaluation of viability and vigor, respectively. Two seed lots were initially evaluated for moisture content, germination, first count, germination speed index, seedling length, seedling dry mass and electrical conductivity. For the pH of exudate test, phenolphthalein (1%) and sodium carbonate (2 and 4 g L-1) solutions were prepared, with three soaking periods (1, 3 and 5 h) and three temperatures (25, 30 and 35 °C). Exudate solution in strong to light pink color indicated viable seeds, whereas very light pink color to colorless indicated non-viable seeds. The primary root protrusion test was performed under 25, 30 and 35 °C, evaluating the primary root protrusion of at least 2 mm, every 12 h until 196 h. The experimental design was completely randomized, with four replicates. pH of exudate test with 1 h of soaking at 25 or 30 °C with 2 g L-1 sodium carbonate solution was promising, but further studies are needed before it is indicated as routine use for the species. Primary root protrusion test is efficient and can be conducted at 35 °C with evaluation after 48 h.

Poly(amidoamine)-type dendrimers (PAMAM) were synthesized by divergent routes, and generations (G0.5, G1.0, G1.5, G2.0 and G2.5) along with hydroxylated half-generation polymers (G0.5-OH, G1.5-OH and G2.5-OH) were characterized by Fourier-transform infrared spectroscopy, thermogravimetric analysis and differential scanning calorimetry. Carbon dioxide (CO2) capture tests were performed using thermogravimetric analysis. Among the absorption temperatures tested, 60 °C was the most promising: 0.77, 1.08, and 1.14 mol CO2 L 1 for G0.5-OH, G1.5-OH and G2.5-OH, respectively, of CO2 and partial pressure of 45 kPa. This showed that dendrimers with larger molecular structures have more hydroxyl groups and consequently capture more CO2. However, at low partial pressures (< 2 kPa), CO2 solubility in PAMAM increased with temperature reduction, confirmed by Henry’s solubility constant (398.4 mol m3 kPa 1, in G2.5-OH at 40 °C). According to the thermodynamic properties of CO2 solubilization, the process was spontaneous (∆Gsol < 0) and exothermic (∆Hsol < 0).

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.

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.

In the Amazon, Euterpe oleracea Mart. (açaí), is part of the identity of traditional communities, and the fruit is integrated into their everyday sociocultural dynamics. Hydrolysis and pyrolysis of residual biomass can be alternatives to yield sugars, ethanol, biochar and bio-oil. The açaí seeds subjected to oxidative pretreatment followed by acid hydrolysis increased cellulose to fermentable sugars (reaching 23.5%) and second-generation ethanol production (17.441 L t−1). Açaí oil (ca. 30%) was extracted using a Soxhlet apparatus (using hexane as solvent) and detected through gas chromatography coupled to mass spectrometry (GC-MS), where acids accounted for 82.43% of the total composition, while alcohols comprised only 13.15%. For pyrolysis, temperatures (500 and 550 °C), time (20 and 30 min), and activation temperature (750 and 800 °C) were evaluated, resulting in yields of ca. 22% for biochar and 30% for bio-oil. For the bio-oil, the main compounds detected by GC-MS were acids (16.3%), aldehydes (13.08%), amides (12.19%), alcohols (6.72%), and phenols (4.64%). The obtained biochar displayed surface area values of 553.7 m2 g−1 and 10% crystallinity, indicating its more amorphous nature.

The Schröeder-van Laar equation to predict the theoretical eutectic melting temperature values was applied to a set of fourteen binary mixtures (UR1 to UR14). The fourteen binary mixtures belong to a structurally diverse group of organic molecules. They are represented by the 5-membered heterocycles containing N-S and N-O rings, flexible methylene chains (RH), semi-rigid semi-fluorinated chains (RF), and hydrogen bonds (HB). A virtual screening totalizing ninety-one possible theoretical combinations was planned. The UR1 to UR14 were prepared by mixing individual components using the calculated mole fractions. The experimental (Te) and theoretical (Tt) temperatures for the eutectic melting points were determined using polarized optical microscopy (POM) and differential scanning calorimetry (DSC) techniques. Heterogeneous mixtures were formed for components with large structural diversity as seen by POM. During the melting of the mixtures, irregular behavior through the segregation of the components was recorded. The study showed that the similarities in structural diversities favor the formation of homogeneous mixtures, with Te values approaching Tt, as predicted by the Schröeder-van Laar equation and by the theory of eutectic mixtures. Liquid crystal properties were affected in homogeneous binary mixtures containing one of the individual liquid crystal components. Schröedervan Schröeder van UR (UR UR14. .

The metal-organic frameworks (MOFs) UiO-66-NH2, UiO-66-2,5-(OH)2, UiO-66-NO2, UiO-66-NDC, and UiO-66-BPDC were synthesized under solvothermal conditions using different functionalized organic linkers. The structures and properties of the samples were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy, and nitrogen adsorption-desorption isotherms. The crystal structures of these functionalized UiO-66(Zr) forms were similar. A series of functionalized UiO-66(Zr) samples were used in the adsorption of carbon dioxide (CO2). UiO-66-NH2 had the highest CO2 adsorption capacity (about 3.35 mmol g-1) due to its small polar -NH2 group. The performance of UiO-66-NH2 in CO2 adsorption at different temperatures was also determined. The amino-functionalized material possessed better adsorption properties at 273 K than at 303 K, while the CO2 working capacity of UiO-66-NH2 was fully recovered after cyclic regeneration. metalorganic metal MOFs (MOFs UiO66NH2, UiO66NH2 UiONH UiO 66 NH2, NH2 NH UiO662,5OH2, UiO6625OH2 UiOOH 2,5 OH 2, 2 5 UiO-66-2,5-(OH)2 UiO66NO2, UiO66NO2 UiONO NO2, NO2 NO UiO-66-NO2 UiO66NDC, UiO66NDC UiONDC NDC, NDC UiO-66-NDC UiO66BPDC UiOBPDC BPDC linkers Xray X ray diffraction spectroscopy analysis microscopy adsorptiondesorption desorption isotherms UiO66Zr UiOZr Zr UiO-66(Zr similar CO2.

We report a facile hydrothermal method for the synthesis of niobium pentoxide (Nb2O5) under two different temperatures, 120 °C (Nb2O5-120) and 150 °C (Nb2O5-150). The obtained materials were characterized by structural, optical and morphological techniques. Also, the photocatalytic properties of the Nb2O5 samples were evaluated in two reactions under ultraviolet (UVC) irradiation: degradation of methylene blue (MB) and indigo carmine (IC) dyes; and esterification of free fatty acids (FFA) present in waste cooking oil (WCO). The Nb2O5 was formed at different temperatures of synthesis, and the increase in temperature did not cause significant changes in the structural and optical characteristics, but resulted in an increased surface area of the synthesized materials. Both synthesized materials showed excellent efficiency for dye photodegradation. The sample Nb2O5-150 presented the best performance for the MB photodegradation, with almost 85% of the removal efficiency. In this case, the adsorption of MB molecules on the surface of the material was high due to the favorable electrostatic interaction and also because of its high surface area. For the IC photodegradation, the adsorption was insignificant, and both samples presented approximately 100% of the removal efficiency. These materials were also promising for the reduction of free fat acids in waste oil by photoesterification. NbO Nb O (Nb2O5 12 C Nb2O5120 (Nb2O5-120 15 Nb2O5150. Nb2O5150 .

ABSTRACT: This study identified and monitored the population fluctuations of insect vectors of Cowpea aphid-borne mosaic virus (CABMV) in experimental orchards in the North and Northwest Regions of the State of Paraná. The experiments were conducted in the cities of Londrina and Paranavaí at the Experimental Research Stations of the Instituto de Desenvolvimento Rural do Paraná-IAPAR-EMATER (IDR-Paraná), Brazil. The study period was from September 2019 to March 2021. In the experiments conducted in Londrina and in Paranavaí, yellow passion fruit plants were grown in trellis systems. Moericke traps were used to capture insects, and collections were performed weekly. Aphids were identified using a taxonomic identification key. The numbers of aphids present in each region were compared, and the populations were correlated with the climate and local precipitation. A total of 1522 and 1340 winged aphids were observed in the experiments in Londrina and Paranavaí, respectively. In Londrina, moderate positive correlations were observed between the number of insects and the maximum and average temperatures, while negative correlations were observed between the number of insects and the minimum temperature and precipitation. In contrast, in Paranavaí, the correlation between aphids and abiotic factors was negative, where maximum temperature was strongly correlated. In both regions, the following seven species of aphid vectors of CABMV were detected: Aphis fabae, Aphis gossypii, Toxoptera citricida, Acyrthosiphon pisum, Brevicoryne brassicae, Macrosiphum euphorbiae and Uroleucon ambrosiae. The population fluctuations of these species were influenced by variations in temperature and precipitation.

Abstract The influence of occupant behaviour in buildings is widely discussed as one of the causes for the gap between energy use estimated via computer simulation and during building operation. Knowing the main drivers for adjustments in building systems is essential to guide the development of mathematical models for such behaviours. The aim of this study is to evaluate the main motivating agents for adjusting windows, luminaires, and air-conditioning in offices. Two offices were monitored using sensors that collected data from the internal environment and user interaction with such systems. Rainfall and external and internal air temperatures were considered influential for the interaction with window systems. The increase in internal and external temperatures had even more influence on interactions with air-conditioners. The main conclusions were: there is influence of the layout of the offices in the sharing and control of windows and efficiency of passive strategies, such as the use of natural and cross ventilation; and there is an influence of the increase in internal temperature compared to external temperature in the predictability of opening windows and turning air-conditioning devices on. operation behaviours luminaires airconditioning conditioning airconditioners. airconditioners conditioners. conditioners air-conditioners strategies ventilation

Abstract This study investigated the effects caused by the thermal shock phenomenon on the temperature distribution in Adhered Ceramic Tiling Systems (ACTS). Cyclic thermal and hygroscopic loads are periodic events resulting from successive and sequential processes of heating by solar irradiation and sudden cooling by heavy rains. Through an experimental program carried out in a ceramic tile prototype composed of porcelain tiles settle with adhesive mortar directly on a concrete wall, monitored the surface temperatures and temperatures at the adhesive mortar-concrete interface were measured during its exposure to heating and cooling cycles according to NBR 15575-4 (ABNT, 2021) procedures. The confinement of thermal energy (heat) inside the structure, after the beginning of cooling, demonstrates that part of the thermal stresses is maintained internally to the structure even after the drop-in surface temperature of the ceramic tile (non-homogeneous distribution), indicating that the movements structural elements of thermal origin will tend to different directions (non-uniform) and, consequently, will cause opposite stresses between layers. This results in a possible increase and concentration of stresses in certain regions that, if critical, will lead to the appearance of damage in the ceramic coating. ACTS. ACTS .

Resumo O estudo investigou os efeitos causados pelo fenômeno do choque térmico sobre a distribuição de temperatura em sistemas de revestimento cerâmico aderido (SRCA). Carregamentos cíclicos térmicos e higroscópicos são eventos periódicos resultado de processos sucessivos e sequenciais de aquecimento por irradiação solar e resfriamentos bruscos por chuvas. Por meio de um programa experimental realizado em um protótipo de revestimento cerâmico composto de placas de porcelanato assentadas com argamassa colante diretamente sobre uma parede de concreto, monitoraram-se as temperaturas superficiais e na interface argamassa colante-concreto durante sua exposição a ciclos de aquecimento e resfriamento, conforme procedimentos da NBR 15575-4 (ABNT, 2021). O confinamento de energia térmica (calor) no interior da estrutura, após o início do resfriamento, demonstra que parte dos esforços térmicos é mantida internamente à estrutura mesmo após a queda de temperatura superficial da placa cerâmica (distribuição não homogênea), indicando que as movimentações estruturais de origem térmica tenderão a ir em direções diferentes (não uniformes) e, consequentemente, ocasionarão solicitações opostas entre camadas. Isso resulta em possível acréscimo e concentração de tensões em determinadas regiões, que, se críticas, levarão ao surgimento do dano no revestimento cerâmico. SRCA. SRCA .

Abstract Cracking can be investigated by infrared thermography, as defects on a surface have different temperatures compared to regions without defects. The temperature of the crack depends on its dimensions, opening and depth, which can be identified by thermography. The possibility of classifying crack damage according to different depths by thermography in heating and cooling regimes and indicating which conditions are most suitable for identifying cracks is evaluated. It is proposed to observe the temperature evolution during the heating and cooling of a mortar slab that has cracks with different depths. The temperature variation of the plate during heating and cooling is monitored by thermograms and thermocouples present on the surface and interior of the plate in regions close to the cracks. It is identified, through the application of Delta-T thermographic contrast, that cracks of greater depth have a greater Delta-T, in modulus, during heating, while cracks of shallower depth have a greater Delta-T during cooling. Cracks are best identified during the cooling phase, as shallower cracks are not identified at the end of heating. dimensions evaluated DeltaT Delta T contrast DeltaT, T, modulus phase

Resumo A fissuração pode ser investigada por termografia de infravermelho, pois defeitos em uma superfície apresentam temperaturas diferentes em relação as regiões sem defeito. A temperatura da fissura é dependente das suas dimensões, abertura e profundidade, nas quais podem ser identificadas pela termografia. Avalia-se o comportamento das temperaturas em regime controlado de aquecimento e resfriamento de fissuras em função de diferentes profundidades e quais as condições mais adequadas para identificar as fissuras. Propõe-se a observação da evolução de temperatura no aquecimento e resfriamento de uma placa de argamassa que possui fissuras com diferentes profundidades. A variação de temperatura da placa no aquecimento e resfriamento é monitorada por termogramas e termopares presentes na superfície e interior da placa em regiões próximas às fissuras. Identifica-se, pela aplicação de contraste termográfico Delta-T, que fissuras de maior profundidade possuem maior Delta-T, em módulo, durante o aquecimento, enquanto fissuras de menor profundidade possuem maior Delta-T no resfriamento. As fissuras são melhor identificadas na fase de resfriamento, pois no fim do aquecimento as fissuras de menor profundidade não são identificadas. infravermelho defeito dimensões Avaliase Avalia se Propõese Propõe Identificase, Identificase Identifica se, Identifica-se DeltaT, DeltaT Delta T, T módulo

Abstract This study aimed to evaluate the effect of thermal treatment on the adhesion quality of bonded joints in high-density wood, specifically Corymbia citriodora and Eucalyptus pellita, using resorcinol formaldehyde and castor oil-based polyurethane adhesives. It was used at temperatures of 160 ºC, 180 ºC and 200 °C, being compared with a control batch. The percentage of failure in the wood was analyzed to evaluate the quality of the bonding. The castor oil-based polyurethane adhesive exhibited higher values of viscosity and solid content than resorcinol formaldehyde. Eucalyptus pellita showed higher shear strength values compared to Corymbia citriodora wood. The increase in temperature reduced the shear strength for both woods. The ratio between the strength of the bonded wood and solid wood, at the same treatment temperature, often exceeded one, indicating the formation of an adhesive-fiber composite, which enhances the strength of the bonded interface, especially for C. citriodora wood. Overall, there was better bonding of Eucalyptus pellita wood with resorcinol formaldehyde, and it exhibited less thermal degradation due to lower mass loss. highdensity high density oilbased oil based adhesives 16 18 20 C °C batch woods one adhesivefiber fiber composite interface Overall loss 1 2

Resumo Esse estudo teve como objetivo avaliar o efeito do tratamento térmico na qualidade da adesão de juntas coladas de madeira de alta densidade, Corymbia citriodora e Eucalyptus pellita utilizando os adesivos resorcinol e poliuretano vegetal à base de óleo de mamona. O tratamento térmico foi realizado nas temperaturas de 160 ºC, 180 ºC e 200 °C, sendo comparadas com um lote controle. A qualidade da colagem foi avaliada através do teste de cisalhamento e análise do percentual de falha na madeira. O adesivo de poliuretano de mamona apresentou maiores valores de viscosidade e teor de sólidos, do que o resorcinol formaldeído. O Eucalyptus pellitaexibiu maiores valores de resistência ao cisalhamento que a madeira de Corymbia citriodora. O aumento da temperatura reduziu a resistência ao cisalhamento para ambas as madeiras. A razão entre a resistência da madeira colada com madeira solida, na mesma temperatura de tratamento, muitas vezes atingiu valores superiores a um, indicando a formação de um compósito adesivo-fibras, que aumenta a resistência da interface colada, especialmente para madeira de C. citriodora. De forma geral, houve uma melhor colagem da madeira de Eucalyptus pellita, com resorcinol formaldeído, e está exibiu menor degradação térmica, devido à menor perda de massa. densidade 16 18 20 C °C controle sólidos formaldeído madeiras solida adesivofibras, adesivofibras fibras, fibras adesivo-fibras geral térmica massa 1 2

Abstract The way residents occupy and operate houses influences the energy consumption. The objective of this paper is to findpatterns of occupant behaviour in actual data for thermal performance simulation.Data on occupancy of rooms and operation of doors and windows were obtained through a database created by means of application of questionnaires in low-income houses located in Florianópolis, southern Brazil. The reference profiles were obtained using cluster analysis, hierarchical and non-hierarchical techniques combined. Such profiles were submitted to computer simulations. The results showed significant variability within the clusters regarding the occupancy and operation of doors and windows. It was possible to verify the impact that different profiles have on the performance of the house, either due to occupancy or heat losses and gains from air changes through doors and windows. The combination of these effects resulted in some profiles that were highly vulnerable to external temperature conditions, while others were able to maintain the internal temperatures more constant.

O objetivo deste trabalho é encontrar padrões de comportamento dos moradores em dados reais para fins de simulação do desempenho térmico. Dados sobre ocupação de cômodos e funcionamento de portas e janelas foram obtidos por meio de um banco de dados criado por meio da aplicação de questionários em habitações de interesse social localizadas em Florianópolis. Os perfis de referência foram obtidos por meio de análise de agrupamento, com técnicas hierárquicas e não hierárquicas combinadas. Tais perfis foram submetidos a simulações computacionais. Os resultados mostraram variabilidade significativa entre os grupos quanto à ocupação e operação de portas e janelas. Foi possível verificar o impacto que diferentes perfis têm no desempenho da casa, seja pela ocupação ou pelas perdas de calor e ganhos com as trocas de ar através de portas e janelas. A combinação desses efeitos resultou em alguns perfis altamente vulneráveis às condições de temperatura externa, enquanto outros foram capazes de manter as temperaturas internas mais constantes. Foi possível verificar que a utilização de perfis de referência baseados em dados reais leva a indicadores de desempenho mais confiáveis. energia térmico Florianópolis agrupamento combinadas computacionais casa externa constantes confiáveis

Resumo O concreto quando exposto a elevadas temperaturas tem suas propriedades alteradas e os processos de recuperação são dependentes da intensidade destas modificações. O objetivo deste artigo foi avaliar a influência das altas temperaturas nas propriedades do concreto, em uma faixa na qual a estrutura ainda pode ser recuperada, e a verificação dos efeitos gerados no material quando submetidos a resfriamento natural e resfriamento rápido. Para isto se desenvolveu o programa experimental com três traços de concreto, os quais foram expostos a temperaturas de 100 ºC, 300 ºC, 450 ºC e 600 ºC; subdivididos em grupos de resfriamento lento e rápido. Com a elevação da temperatura, intensificam-se os processos de fissuração e alterações microestruturais, as quais geram redução nas resistências mecânicas e o aumento da absorção. Verificou-se que o módulo de elasticidade foi a propriedade mais afetada por estas alterações. As correlações entre o módulo de elasticidade e as demais propriedades foram acompanhadas pelo aumento da microfissuração do concreto, perda de água e decomposição das fases da pasta, sendo observada posterior reidratação da etringita durante o resfriamento do concreto. modificações recuperada rápido 10 30 45 60 temperatura intensificamse intensificam microestruturais absorção Verificouse Verificou pasta 1 3 4 6

Abstract Concrete, when exposed to high temperatures, has its properties changed, and the recovery processes depend on the intensity of these changes. This paper aimed to evaluate the influence of high temperatures on concrete properties and verify the effects generated in the material when submitted to natural and fast cooling. Three different concrete mixes were exposed to temperatures of 100 °C, 300 ºC, 450 ºC, and 600 ºC, subdivided into slow and fast cooling groups. With the increase in temperature, cracking processes and microstructural alterations intensified, generating reductions in mechanical strength and increases in absorptions. This study has identified that the elastic modulus was the property most affected by these changes. The correlations between the elastic modulus and the other properties were accompanied by increased concrete micro-cracking, water loss, and decomposition of paste phases. Also, it was found an effect of ettringite rehydration during concrete cooling.
