Seeking a viable alternative to fossil fuels as the primary energy source, bioethanol has emerged as a promising second-generation fuel derived from lignocellulosic biomass. With Brazil ranking pineapple as the third most produced fruit in temporary crops, this study aims to assess the impact of chemical pretreatment techniques, specifically organosolv and diluted acid, on the residual biomass of Pérola pineapple peel to enhance bioethanol production. Employing an experimental design that incorporates temperature, reaction time, and varying concentrations of organic solvent, the study examines their effects on the susceptibility of the substrate to saccharification for future bioethanol generation. Factors such as alphacellulose, hemicellulose, and lignin were evaluated in triplicate and subjected to statistical analysis using the Tukey test with a confidence level of 95%. Upon application of the pretreatment methods, it was observed that the organosolv solvent approach (utilizing water and ethanol) with sulfuric acid exhibited superior sugar conversion, yielding the highest concentration of xylose at 9.13 g L-1. Additionally, the pretreated biomass contained 1.38 g L 1 of cellobiose, 3.11 g L-1 of arabinose, and 3.76 g L-1 of glucose. This technique demonstrates promising potential for obtaining fermentable sugars crucial for bioethanol production. source secondgeneration second generation crops techniques production temperature time alphacellulose hemicellulose 95 95% methods utilizing ethanol conversion 913 9 13 9.1 L1.

Fruits of Schinus terebinthifolia Raddi were investigated. A fast and efficient method for the simultaneous determination of 11 polyphenolic substances by high performance liquid chromatography-diode array detector (HPLC-DAD) was applied. Limits of quantification ranged between 0.78 and 3.14 mg L-1. High concentrations of kaempferol were found. An exploratory evaluation was performed using principal component analysis (PCA) for fruit origin differentiation. Total phenolic content (TPC) ranged from 274 to 517 mg GAE 100 g-1; total flavonoid content (TFC) ranged from 101 to 283 mg QE 100 g-1. In vitro analyses showed that antioxidant capacity with 2,2-diphenyl-1-picrylhydrazyl (DPPH) ranged from 1.7 to 7 µM DPPH 100 g-1. The bacteriostatic and bactericidal effect were also evaluated against: Bacillus subtilis, B. cereus, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Salmonella choleraesuis, Candida albicans and C. glabrata, using broth microdilution assay. It can be inferred that S. terebinthifolia Raddi fruit has the potential to act as an ally in the search for new alternatives in the action against pathogens, and it can be used as a potential natural antioxidant and antimicrobial agent. Metals (Cu, Fe, Mg, Mn and Zn) were also determined by flame atomic absorption spectrometry (FAAS), with emphasis on high concentrations of Mg, Zn and Fe. investigated 1 chromatographydiode chromatography diode HPLCDAD HPLC DAD (HPLC-DAD applied 078 0 78 0.7 314 3 14 3.1 L1.

ABSTRACT Potassium is one of the most important nutrients for the cotton plant, being an element that participates in many physiological functions. In addition, its adequate availability favors better production performance of the crop. Therefore, the objective of this study was to evaluate the agronomic components in naturally colored cotton cultivars fertilized with potassium doses in the Brazilian semiarid region. For this, two experiments were conducted at Rafael Fernandes Experimental Farm, located in the municipality of Mossoró, RN, from July to November 2019 and July to November 2021. The experimental design was randomized blocks, arranged in split plots, with four repetitions. Potassium doses (0, 60, 120, 180, and 240 kg ha-1 of K2O) were allocated in the plants; and four naturally colored cotton cultivars (BRS Rubi, BRS Safira, BRS Verde, and BRS Topázio) were allocated in the subplots. Colored cotton cultivars respond to potassium fertilization depending on the edaphoclimatic conditions to which they are exposed. BRS Topázio cultivar had higher lint cotton yield and fiber percentage in both growing seasons, highlighting its potential for the region. The dose of 240 kg ha-1 of K2O increased the yield of colored cotton, in second crop cultivation. The cultivars BRS Safira, BRS Rubi, and BRS Verde were not very productive. plant functions addition Therefore region Farm Mossoró RN 201 2021 blocks plots repetitions 0, 0 (0 60 120 180 24 ha1 ha 1 ha- KO K O plants Rubi Safira subplots exposed seasons cultivation productive 20 202 ( 6 12 18 2

Résumé L’objectif du travail est de documenter l’existence d’un modèle de punition-récompense dans les pratiques éducatives envers les mineurs, à Querétaro, région centre-bas du pays, au cours des années 1950; considéré comme une étape de transition vers la Modernité, dans un environnement socioculturel dominé par les institutions conservatrices. Les recherches précédentes ont montré l’existence de châtiments physiques et psychologiques dans les salles de classe, acceptés par la société, où les mineurs ne le considéraient pas comme de la violence, mais comme une activité d’enseignement. Les travaux universitaires se sont concentrés sur la cruauté des châtiments corporels et le rôle de l’enseignement dans l’exercice du pouvoir et de la domination, mais sans prêter attention aux enfances et aux dynamiques dans lesquelles, le correctif fait partie d’un quotidien où abondent aussi les stimuli basés sur la récompense. Pour montrer cela, une recherche a été menée dans le cadre de l’Histoire Sociale et Culturelle, en utilisant des sources officielles et des références telles que: photographies, publicités, bandes dessinées ou romans, à travers lesquelles sont mis en évidence certains des stimuli et des satisfactions que les familles, souvent par un lourd sacrifice économique, donnaient à leurs enfants pour pouvoir aller à l’école. Il ressort des conclusions que ce que l’on considérait auparavant comme des pratiques communes ne le sont plus au fil du temps, et ce qui était impensable, avec le progressisme, c’est maintenant la norme. Le rejet actuel de la violence physique et psychologique entre et vers la population scolaire ne fait pas exception.

Streszczenie Streszczenie Celem pracy jest udokumentowanie istnienia modelu kary i nagrody w praktykach edukacyjnych wobec nieletnich w Querétaro, regionie środkowo-zachodnim kraju, w latach 1950-1960; okres ten uważany jest za etap przejścia do nowoczesności, w społeczno-kulturowym środowisku zdominowanym przez konserwatywne instytucje. Badania wcześniejsze pokazują istnienie kar fizycznych i psychicznych w salach lekcyjnych, akceptowanych przez społeczeństwo, gdzie nieletni nie traktowali tego jako przemocy, a jako działalność pedagogiczną. Prace akademickie skupiały się na ujawnianiu okrucieństwa kar fizycznych i roli nauczycieli w wywieraniu relacji władzy i dominacji, ale bez zwracania uwagi na dzieciństwo ani dynamikę, w której kara jest częścią codzienności, obok obfitujących w bodźce opartych na nagrodzie. Aby to udowodnić, przeprowadzono badania z wykorzystaniem podejścia historii społecznej i kulturowej, korzystając z oficjalnych źródeł i odniesień, takich jak: fotografie, reklamy, komiksy lub powieści, poprzez które ukazano niektóre bodźce i zaspokajacze, które rodziny, często kosztem dużego poświęcenia ekonomicznego, dawały swoim córkom i synom, aby mogły chodzić do szkoły. Wnioski wskazują, że to, co kiedyś uważano za powszechne praktyki, z czasem przestaje nimi być; a to, co było nie do pomyślenia, stało się teraz normą dzięki postępowi. Obecny sprzeciw wobec przemocy fizycznej i psychicznej wśród i wobec populacji szkolnej nie jest wyjątkiem.

Resumen El objetivo del trabajo es documentar la existencia de un modelo de castigo-recompensa en las prácticas educativas hacia menores, en Querétaro, región centro-bajío del país, durante la década de 1950; considerada una etapa de transición a la Modernidad, en un entorno sociocultural dominado por las instituciones conservadoras. Las investigaciones previas muestran la existencia de castigos físicos y psicológicos en las aulas, aceptados por la sociedad, donde las y los menores no lo consideraban como violencia, sino quehacer docente. Los trabajos académicos se centraron en exhibir la crueldad de los castigos físicos y el papel de la docencia al ejercer relaciones de poder y dominación, pero sin prestar atención a las infancias ni a las dinámicas en las que, el correctivo es parte de una cotidianeidad en la que también abundan estímulos basados en la recompensa. Para dar muestra de ello, se desarrolló una investigación bajo el enfoque de la Historia Social y Cultural, usando fuentes oficiales y referencias como: fotografías, anuncios publicitarios, historietas o novelas, a través de las cuales se evidencian algunos de los estímulos y satisfactores que las familias, muchas veces mediante un fuerte sacrificio económico, daban a sus hijas e hijos para poder ir a la escuela. Entre las conclusiones destaca que, lo que antes se consideraban prácticas comunes, al paso del tiempo ya no lo son; y lo que era impensable, con el progresismo, ahora es la norma. El rechazo actual de la violencia física y psicológica entre y hacia la población escolar, no es la excepción.

Abstract This paper aims to document the existence of a punishment-reward model in educational practices towards minors in Querétaro, a central-bajío region in Mexico, during the 1950s. This decade was considered a transitional stage to Modernity, in a sociocultural environment dominated by conservative institutions. Previous research shows the existence of physical and psychological punishment in classrooms, accepted by society, where minors did not perceive them as violence, but as a regular part of teaching. Academic research focused on exposing the cruelty of physical punishment and on the role of teaching in exercising relations of power and domination, but without focusing on the children or the dynamics in which correction was part of everyday life where reward-based stimuli were also abundant. To demonstrate this, research was conducted under the approach of Social and Cultural History, using official sources and references such as photographs, advertisements, comic books, or novels, through which are evidenced some of the stimuli and satisfiers that families, often through a strong economic sacrifice, provided to their children so that they were able to go to school. Among the conclusions, it is noteworthy that what was once considered common practices, over time, is no longer so, and that what was unthinkable, with progressivism, is now the norm. The current rejection of physical and psychological violence among and towards the school population is no exception.

ABSTRACT The canonical correlation is used to correlate groups of distinct variables. The objective of this study was to use canonical correlation analysis to evaluate the interaction between water quality attributes clogging-causing and the hydraulic performance of non-pressure compensating drippers operating with dilutions of aquaculture effluent in well water. The experiment was in a completely randomized design in a split-split-plot scheme with three replicates, with five dilutions in the plots (Dilution 1: 100% aquaculture effluent; Dilution 2: 75% aquaculture effluent + 25% well water; Dilution 3: 50% aquaculture effluent + 50% well water; Dilution 4: 25% aquaculture effluent + 75% well water; and Dilution 5: 100% well water), three emitters in the sub-plots (ST (1.6 L h-1), SL (1.6 L h-1) and NJ (1.7 L h-1)), and three operating times in the sub-subplots (0, 80 and 160 hours, in which 0 hours operating time means the start of evaluations). The statistical analyses performed were correlation matrix and canonical analysis. The canonical correlation analysis indicated that when the concentrations of attributes increase, the hydraulic performance of the drippers decreases. The interaction of this group of attributes indicates that the clogging of drippers operating with the five dilutions of aquaculture effluent in well water occurs by the combined action of physical, chemical, and biological agents. The ST dripper was the least sensitive to the group of quality attributes of the dilutions, whereas the most sensitive was the SL dripper. variables cloggingcausing causing nonpressure non pressure splitsplitplot split plot replicates 1 100 2 75 25 3 50 4 5 water, , water) subplots sub 1.6 16 6 (1. h1, h1 h h-1 1.7 17 7 h-1)) subsubplots 0, (0 8 evaluations. evaluations . evaluations) increase decreases physical chemical agents 10 1.

RESUMO A correlação canônica é usada para correlacionar grupos de variáveis distintas. O objetivo deste estudo foi utilizar análise de correlação canônica para avaliar a interação entre atributos de qualidade da água causadores de entupimento e o desempenho hidráulico de gotejadores não autocompensantes operando com diluições de efluente de aquicultura em água de poço. O experimento foi conduzido em delineamento inteiramente casualizado, em esquema de parcelas subsubdivididas, com três repetições, com cinco diluições nas parcelas (Diluição 1: 100% de efluente de aquicultura; Diluição 2: 75% de efluente de aquicultura + 25% de água de poço; Diluição 3 : 50% efluente de aquicultura + 50% água de poço; Diluição 4: 25% efluente de aquicultura + 75% água de poço; e Diluição 5: 100% água de poço), três emissores nas subparcelas (ST (1,6 L h-1) , SL (1,6 L h-1) e NJ (1,7 L h-1)), e três tempos de operação nas subsubparcelas (início do experimento, 80 e 160 horas, em que 0 horas de operação significa o início das avaliações). As análises estatísticas realizadas foram matriz de correlação e análise canônica. A análise de correlação canônica indicou que quando as concentrações dos atributos aumentam, o desempenho hidráulico dos gotejadores diminui. A interação desse grupo de atributos indica que o entupimento dos gotejadores que operam com as cinco diluições de efluente de aquicultura em água de poço ocorre pela ação combinada de agentes físicos, químicos e biológicos. O gotejador ST foi o menos sensível ao grupo de atributos de qualidade das diluições, enquanto o mais sensível foi o gotejador SL. distintas casualizado subsubdivididas repetições 1 100 2 75 25 50 4 5 poço, poço) 1,6 16 6 (1, h1 h h-1 1,7 17 7 h1, h-1)) 8 avaliações. avaliações . avaliações) aumentam diminui físicos biológicos 10 1, (1 h- (

It is concluded that the use of acids is necessary to lower the pH of the water and neutralize the carbonates.

ABSTRACT Tamarind (Tamarindus indica L.) is a species with promising potential for commercial production; therefore, studies involving practices of conducting culture in the initial stage are essential. The present study aimed to evaluate different shading levels and substrate compositions in the seedling production of tamarind. The experimental design was completely randomized in a 4×4 factorial scheme, four levels of shading (0%, 18%, 30%, and 50%) and four substrates (pine bark-based substrate pure and mixed with 50% vermiculite, and sphagnum peat-based substrate pure and mixed with 50% vermiculite), with four replicates of four seedlings. Growth and biometric relationships were evaluated at 40 and 98 d after transplantation (DAT). The results reported that seedlings formed on the sphagnum peat-based substrate on pure or associated with vermiculite at 98 DAT had a height greater than 35 cm and a total 8.5 g DM. In contrast, seedlings produced in pine bark-based substrate did not reach 20 cm in height and had less than 3 g total DM. The condition of 30% and 50% shading promoted greater growth in height, reaching an average height greater than 40 cm, while in the full sun environment, seedlings showed an average of less than 35 cm; however, for the other variables, full sun environment did not differ from 30% shading, producing good quality seedlings. Thus, the cultivation of seedlings in an environment with 0% or 30% shading, associated with the sphagnum peat-based substrate pure or mixed with 50% vermiculite promoted the production of tamarind seedlings with vigorous growth. In the best environments, the best substrates increased, on average, 41.3% number of leaves, 80.5% shoot dry mass, 56.8% root dry mass, and 71.0% total dry mass. In the best substrates, the best environments increased, on average, 18.0% number of leaves, 20.7% shoot dry mass, 8.7% root dry mass, and 14.3% total dry mass.

ABSTRACT: One of the main issues related to the management of forage legumes is the fact that these plants can be found in a broad diversity of morphology, structures and growth habits. This study evaluated the structural and productive characteristics of forage legumes with different growth habits [Clitoria ternatea L.; Desmanthus pernambucanus (L.) Thellung; and Stylosanthes spp. cv. Campo Grande], in response to two harvesting frequencies (60 and 90 days). The experimental design was completely randomized in blocks, with a split-plot scheme and four replications (n=4). The type of forage legume influenced the number of secondary branches, the number of leaves per branch, leaf area index (LAI), light interception (LI), percentage of leaves and stems (%), leaf/stem ratio, and pod production (P<0.05). D. pernambucanus had the lowest LI and LAI (P < 0.05). Stylosanthes spp. cv. Campo Grande and C. ternatea showed a greater leaf percentage and leaf/stem ratio (P < 0.05). There was an effect of the harvesting frequency on the percentage of stems, leaves, pod production, and total production (P < 0.05). Longer harvesting frequencies affected differently these legumes, especially the accumulation of stems in D. pernambucanus, which displayed an intense increase after 60 days of growth. The choice of the best harvesting frequency for these legumes evaluated should consider the proposal of the usage. In our study, it was shown that harvesting at 60 days did not affect the total forage mass accumulated, which possibly is the most advantageous choice. ABSTRACT morphology Clitoria L. L (L.

RESUMO: Uma das principais questões relacionadas ao manejo de leguminosas forrageiras é o fato de que essas plantas podem ser encontradas em uma ampla diversidade de morfológica, estruturais e de hábitos de crescimento. O objetivo deste estudo foi avaliar características morfológicas, estruturais e produtivas de leguminosas forrageiras com diferentes hábitos de crescimento [Clitoria ternatea L.; Desmanthus pernambucanus (L.) Thellung; e Stylosanthes spp. cv. Campo Grande], em resposta a duas frequências de colheita (60 e 90 dias). O delineamento experimental foi inteiramente casualizado em blocos, com esquema de parcelas subdivididas e quatro repetições (n=4). O tipo de leguminosa forrageira influenciou no número de ramos secundários, número de folhas por ramo, índice de área foliar (IAF), interceptação luminosa (IL), porcentagem de folhas e colmos (%), razão folha/colmo e produção de vagens (P<0,05). D. pernambucanus apresentou os menores IL e IAF (P<0,05). Stylosanthes spp. cv. Campo Grande e C. ternatea apresentaram maior porcentagem de folhas e relação folha/colmo (P<0,05). Houve efeito da frequência de colheita na porcentagem de produção de hastes, folhas e vagens e na produção total (P<0,05). Frequências de colheita mais longas afetaram de forma diferente as leguminosas forrageiras avaliadas, principalmente o acúmulo de caules em D. pernambucanus, que apresentou aumento intenso após 60 dias de crescimento. A escolha da melhor frequência de colheita para essas leguminosas avaliadas deve levar em consideração a sua forma de uso. No presente estudo, foi demonstrado que a colheita aos 60 dias não afetou a massa forragem total acumulada, o que possivelmente é a escolha mais vantajosa. RESUMO morfológica morfológicas Clitoria L.

ABSTRACT The objective of this research was to evaluate the biochemical and physiological quality of peanut cultivar seeds under periods of imbibition and drying. A completely randomized statistical design was adopted, in factorial scheme, with four replications. The three peanut cultivars were: BR1, BRS 151-L7, and IAC 505. The imbibition and drying periods were: 0, 12, 24, 36 and 48 hours. The seeds were imbibition with the aid of germitest paper and distilled water, then dried on a metal screen in a plastic box with silica, according to the periods studied. Physiological variables were evaluated (percentage of germination, normal seedlings, abnormal seedlings in the first count and abnormal seedlings in the final count, accelerated aging, seedling length, electrical conductivity, speed index, and average germination time) and biochemical variables (sugar concentration total, reducing sugars, hydrogen peroxide, total superoxide dismutase proteins, and total proteins). The desiccation tolerance of peanut seeds is reduced as the period of water absorption followed by drying increases. Seeds of cultivar IAC 505 have greater tolerance to imbibition and subsequent desiccation compared to seeds of BR1 and BRS 151-L7. adopted scheme replications BR 151L7, 151L7 L 151 L7, L7 151-L7 0 12 24 3 4 hours silica studied percentage aging length conductivity index time sugar sugars peroxide proteins proteins. . proteins) increases 50 151L7.

ABSTRACT present study aimed to determine the effects of different light restriction levels (shading levels) on soybean genetic parameters using a Bayesian multi-trait model (MTM) and select high-yielding soybean cultivars. Eighteen commercial soybean cultivars bred in a soybean breeding program were evaluated over two agricultural seasons. Three shading levels were used over two agricultural crop seasons, giving six treatments (light restriction × crop season). The experiments were arranged in a randomized complete block design with six treatments replicated thrice. The genetic values and parameters were estimated using a Monte Carlo Markov Chain algorithm. Broad-sense heritability range from 0.2093 to 0.7153. The lowest genotypic variance estimate was observed at the 45 % photosynthetically active radiation level in the 2019/2020 crop season year compared with that of other shading levels. Furthermore, a 40 % selection intensity had the highest soybean yield under different shading levels. The Bayesian MTM combined with the factor analysis and genotype-ideotype distance method can be used to evaluate and select soybean genotypes considering different shading levels. The soybean cultivars 8579RSF, NS8338, NS7901, NS7667, RK8115, and 8473RSF had higher genetic potential than other cultivars under different shading levels. multitrait multi trait (MTM highyielding high yielding seasons season. . season) thrice algorithm Broadsense Broad sense 02093 0 2093 0.209 07153 7153 0.7153 4 20192020 2019 2020 2019/202 Furthermore genotypeideotype genotype ideotype 8579RSF RSF NS8338 NS NS7901 NS7667 RK8115 RK 0209 209 0.20 0715 715 0.715 2019202 201 202 2019/20 NS833 NS790 NS766 RK811 020 20 0.2 071 71 0.71 201920 2019/2 NS83 NS79 NS76 RK81 02 2 0. 07 7 0.7 20192 2019/ NS8 NS7 RK8

Abstract Amburana cearensis tree is used in various applications, from artisanal to pharmaceutical use. However, the gum extracted from its exudate has not yet been investigated. This study aimed to the physicochemical and structural characterization of Amburana cearensis Gum (AcG) by elemental, rheological, and thermal analyses, X-ray diffraction (XRD), high-Performance Liquid Chromatography (HPLC), Gel Permeation Chromatography (GPC), Infrared Spectroscopy (FTIR), UV-Vis spectroscopy and nuclear magnetic resonance (NMR). Additionally, a hemolytic assay was performed to evaluate the biocompatibility of AcG using human erythrocytes. The results showed that AcG consists of β-D-Galactopyranose monomers linked by glycosidic bonds (1→3). At the same time, the side chains exhibit β-Galactopyranose (1→6) and α-L-Arabinofuranoside (1→3,6) monomers as non-reducing terminals, whose biocompatibility was excellent in the model used. AcG was described for the first time as a biopolymer that could have broad applications in the pharmaceutical and cosmetic industries, justifying the interest in further studies about AcG applications. use However investigated (AcG elemental rheological analyses Xray X ray XRD, XRD , (XRD) highPerformance high Performance HPLC, HPLC (HPLC) GPC, GPC (GPC) FTIR, FTIR (FTIR) UVVis UV Vis NMR.

Laser flash photolysis studies (λ = 355 nm) on the characterization and reactivity for the triplet excited state of 2-methoxythioxanthone, 2-benzyloxythioxanthone, and 2-(n-propoxy) thioxanthone revealed that the transients generated in their excitation, in acetonitrile, have absorption bands with maxima at 310 and 620 nm. These transients decayed by a mixed 1st and 2nd order kinetics, with a lifetime of 5.3 μs for 2-methoxythioxanthone and benzyloxythioxanthone and 3.9 μs for 2-(n-propoxy) thioxanthone. In methanol, ethanol, and 2-propanol, a new absorption at 430-460 nm was observed, which was attributed to their corresponding ketyl radical (the second-order quenching rate constant (kq) is ca. 105 L mol-1 s-1). The energy transfer rate constants for trans-stilbene, 1-methylnaphthalene, and 1,3-cyclohexadiene were diffusion-controlled, indicating a triplet energy for these alkoxy thioxanthones higher than 61 kcal mol-1. The quenching rate constant observed for 1,4-cyclohexadiene (ca.109 L mol-1 s-1) suggests that the lowest energy triplet excited state for these thioxanthones must have nπ* character. For phenols and indole (kq ca. 109 L mol-1 s-1), the reaction mechanism must involve the initial formation of a triplet exciplex, followed by a coupled electron/proton transfer. For triethylamine and 1,4-diazabicyclo[2.2.2]octane (kq ca. 109 L mol-1 s-1) it was observed the formation of the radical anion of the alkoxy thioxanthones formed from electron transfer (λ = 410 nm). λ 35 2methoxythioxanthone, 2methoxythioxanthone methoxythioxanthone 2 methoxythioxanthone, 2benzyloxythioxanthone, 2benzyloxythioxanthone benzyloxythioxanthone, 2-benzyloxythioxanthone 2npropoxy npropoxy n propoxy 2-(n-propoxy excitation acetonitrile 31 62 st nd kinetics 53 5 3 5. 39 9 3. methanol ethanol 2propanol, 2propanol propanol propanol, 2-propanol 430460 430 460 430-46 secondorder second kq ca 10 mol1 mol 1 mol- s1. s1 s . transstilbene, transstilbene trans stilbene, stilbene trans-stilbene 1methylnaphthalene, 1methylnaphthalene methylnaphthalene methylnaphthalene, 1-methylnaphthalene 1,3cyclohexadiene 13cyclohexadiene cyclohexadiene 1,3 diffusioncontrolled, diffusioncontrolled diffusion controlled, controlled diffusion-controlled 6 mol1. 1. 1,4cyclohexadiene 14cyclohexadiene 1,4 4 ca.109 ca109 (ca.10 s-1 nπ character s1, , exciplex electronproton proton 1,4diazabicyclo2.2.2octane 14diazabicyclo222octane diazabicyclooctane diazabicyclo 2.2.2 octane 41 43046 43 46 430-4 3cyclohexadiene 13 1, 4cyclohexadiene 14 ca.10 ca10 (ca.1 s- 4diazabicyclo2 2octane 222 2.2. 4304 430- ca.1 ca1 (ca. 4diazabicyclo 22 2.2 (ca 2.

RÉSUMÉ Les Méthodes Artistiques comme Moyen d’Envisager les Possibilités de Construction du Genre et de ses Relations – Sur la base d’un projet de recherche-action en collaboration avec une classe de lycée, nous discutons des possibilités que les méthodologies artistiques apportent aux analyses et aux réflexions collectives en vue de promouvoir la conscience politique des jeunes. À travers des moments d'exploration esthético-politique, dans lesquels le Théâtre de l’Opprimé et Photovoice ont été mobilisés, les jeunes ont réfléchi à leurs expériences et problèmes quotidiens, la violence dans les relations amoureuses apparaissant comme le thème le plus significatif. Des acteurs locaux ont été ajoutés à la réflexion commune des jeunes, et les récits visuels réalisés par deux grou-pes ont été discutés. Cet article reconnaît le potentiel des arts pour problématiser les relations et les constructions de genre, pour impliquer les participants de manière émotionnelle et subjective, et comme moyen de politiser un problème individuel ‘apparent’. dEnvisager d Envisager dun rechercheaction recherche action lycée dexploration exploration esthéticopolitique, esthéticopolitique esthético politique, esthético-politique lOpprimé l Opprimé mobilisés quotidiens significatif groupes grou pes discutés genre subjective ‘apparent. apparent ‘apparent . ‘apparent’

ABSTRACT The Artistic Methods as a Way to Look at the Possibilities of Construction of Gender and its Relations – Based on a collaborative action-research project with a high school class, we discuss the possibilities that artistic methodologies bring to collective analysis and reflec-tions in order to promote youth political consciousness. Through moments of aesthetic-political exploration, in which the Theatre of the Oppressed and Photovoice were mobilised, the young people reflected on their everyday experiences and problems, with dating violence emerging as the most significant theme. Local actors were added to the joint reflection between the young people, and visual narratives made by two groups were discussed. This article recognises the potential of the arts to problematise gender relations and constructions, to emotionally and subjectively involve par-ticipants, and as a way of politicising an ‘apparent’ individual problem. actionresearch action research class reflections reflec tions consciousness aestheticpolitical aesthetic exploration mobilised problems theme discussed constructions participants, participants par ticipants, ticipants par-ticipants ‘apparent apparent problem

ABSTRACT Considering that the expression of sweetpotato characters may vary according to the environment, we aimed to evaluate the nutritional performance of nine genotypes in two different regions. Experiments were carried out in Itabaiana, SE and Gama, DF, in 2015/2015 and 2015/2016 crop years. The experimental design was a four-replicate randomized block design of 10 plants per row, spaced 75 cm between rows and 40 cm between plants. The treatments were the Beauregard cultivar and eight clones 6, 8, 9, 33, 50, 66, 75, 79; in addition, two local cultivars (Olho Roxo and Ourinhos) were used as controls for sugar analysis. They were evaluated for dry matter, total carotenoid and betacarotene content; and the content of fructose, glucose, sucrose, and total soluble solids. Total and soluble sugars evaluations were performed only in 2015/2016. The resulting data underwent analysis of individual and pool variances, simple correlation, and grouping of treatment means by a Scott-Knott test. It was verified that dry matter, brix, total carotenoids, betacarotene, and sugar (fructose and glucose) levels were different in Itabaiana-SE and Gama-DF evaluations. These findings demonstrate the importance of regional validations of sweetpotato quality traits under different Brazilian conditions. environment regions Itabaiana Gama DF 20152015 2015 2015/201 20152016 2016 years fourreplicate four replicate 1 row 7 4 6 8 9 33 50 66 79 addition Olho Ourinhos matter fructose glucose sucrose solids variances correlation ScottKnott Scott Knott test brix carotenoids ItabaianaSE GamaDF conditions 2015201 201 2015/20 3 5 201520 20 2015/2 20152 2 2015/

ABSTRACT: It is known that floriculture is very important for the world economic scenario. Nevertheless, the vase life of cut flowers is determined by a short time span. This study evaluated the spectral behavior during leaf degradation of lisianthus (Eustoma grandiflorum) flower stems in the postharvest, in different preservative solutions, and estimating its leaf pigments by hyperspectral data. Lisianthus floral stems were subjected to preservative solutions with different concentrations of sucrose, glucose, phytohormones and deionized water. Leaves from these stems were collected every 4 days for further hyperspectral analysis. Spectra was determined in laboratory with a sensor collecting at the range of 350-2500 nm. In order to analyze the use of the spectra to detect the performance of the preservative solutions, statistical tests were used at each wavelength. Pigment prediction was assessed by the CAR/CLF ratio (Ratio between Carotenoids and Chlorophyll) from the spectral curves, using PLSR and RRMSE. The glucose-based solutions registered positive effects on the preservation of floral stems, especially at the dose of 180 g/L. The solutions based on sucrose and phytohormones registered similarities in the spectral curves among the doses, demonstrating equality in leaf preservation. The discriminant analyses demonstrated there was statistical difference in the spectral responses in the doses for each solution used. The CAR/CLF ratio had reasonable coefficients of 0.6 and RRMSE below 6.99%. The hyperspectral analyses presented a potential for the evaluation of leaf degradation in lisianthus floral stems in different pulsing solutions used in the postharvest.

RESUMO: Sabe-se que a floricultura é muito importante para o cenário econômico mundial, porém a vida útil de vaso das flores de corte é determinada por um pequeno intervalo de tempo. O estudo procurou avaliar o comportamento espectral durante a degradação foliar de hastes florais de lisianthus (Eustoma grandiflorum) na pós-colheita, em diferentes soluções conservantes, e estimar pigmentos foliares a partir dos dados hiperespectrais. As hastes florais de lisianthus foram submetidas a soluções conservantes de diferentes concentrações de sacarose, glicose, distintos fitormônios e água deionizada. Foram coletadas folhas dessas hastes a cada quatro dias para posterior análise hiperespectral. A fim de analisar o uso dos espectros para detectar o desempenho das soluções conservantes, foi utilizado testes estatísticos em cada comprimento de onda entre estas soluções. Foi avaliado a predição de pigmentos através da razão CAR/CLF (Razão entre Carotenoides e Clorofila) a partir das curvas espectrais, tendo o PLSR e RRMSE como indicadores da eficiência dos resultados. As soluções a base de glicose registraram efeitos positivos na conservação das hastes florais principalmente na dose de 180 g/L. Já as soluções a base de sacarose e fitormônios registraram semelhanças nas curvas espectrais entre as doses, mostrando-se igualdade na conservação das folhas. As análises discriminantes demostraram que houve diferença estatística nas respostas espectrais nas doses para cada solução utilizada. A razão CAR/CLF teve coeficientes razoáveis de 0,6 e RRMSE abaixo de 6,99%. As análises hiperespectrais apresentaram potencial na avaliação da degradação foliar de hastes florais de lisianthus em diferentes soluções pulsing utilizadas na pós-colheita.
