Food contamination is a public health problem, and the search for natural additives to increase food stability and safety is challenging. This research aimed to study nanoemulsions produced with coriander essential oil and kefiran, an exopolysaccharide extracted from kefir grains. The composition of coriander essential oil was evaluated, revealing linalool as the main component. An experimental design consisting of six trials was conducted. The NE2 formulation (0.5% kefiran and 1.5% coriander essential oil) exhibited smaller particle size, monodispersity, a lower centrifugal stability coefficient, and higher absolute zeta potential values (> 30 mV), indicating high electrical stability. Morphology, thermal stability, and toxicity tests were performed. The minimum bactericidal concentration was determined and applied to commercial cheese. Thermal stability tests demonstrated an increase in the stability of NE2 compared to its individual components, and it was also proven to be non-toxic. The concentration of 25% m v-1 was identified as the minimum bactericidal concentration and was applied to commercial cheese. problem challenging grains evaluated component conducted NE 0.5% 05 0 5 (0.5 15 1 1.5 size monodispersity coefficient > ( 3 mV, mV , mV) Morphology performed cheese components nontoxic. nontoxic non toxic. toxic non-toxic 25 v1 v v- 0.5 (0. 1. 2 0.

RESUMO A busca por novas tecnologias capazes de proporcionar benefícios para uma alimentação saudável tem sido meta mundial. A presença de alimentos ricos em carotenoides pode ser fundamental para prevenir sérios problemas de saúde. Aliar alimentos com altos teores de carotenoides e acessíveis para a maior parte da população é fundamental. A alface (Lactuca sativa L.) se apresenta como uma espécie adequada para investir em pesquisas com biofortificação a partir de melhoramento genético. Assim, o objetivo com este estudo foi selecionar híbridos de alface visando à obtenção de populações com potencial agronômico e biofortificadas para carotenoides. Dez linhagens de alface cadastradas no Software “BG α Biofort” foram utilizadas nas hibridações. Os cruzamentos para obtenção dos híbridos foram planejados envolvendo duas linhagens ricas em pelo menos um dos pigmentos (clorofila e carotenoides) sendo obtidos 24 híbridos experimentais. Foram avaliados 37 genótipos (linhagens, híbridos e cultivares comercias) em delineamento em blocos casualizados quanto as variáveis agronômicas e teores de clorofila e carotenoides. Foi verificado que os híbridos 12 (UFU-189#3#4#1 × UFU MC BIOFORT 2) e 25 (UFU66#4#2 × UFU-189#3#4#1) possuem potencial para obtenção de populações de duplo propósito (produtividade e biofortificada para carotenoide). O híbrido 27 (UFU66#4#2 × UFU MC BIOFORT1) foi o que apresentou maior equilíbrio para pigmentos. Sugere-se a obtenção de populações F2 dos híbridos 12, 25 e 27 visando a obtenção de novas cultivares de alfaces biofortificadas vermelhas e verdes, para os segmentos de alface crespa, americana, mini e romana. mundial saúde Lactuca L.

ABSTRACT The search for new technologies capable of providing benefits to healthy eating is a global goal. The consumption of foods rich in carotenoids can prevent serious health problems. Thus, the availability of foods high in carotenoids that are accessible to the majority of the population is essential. Lettuce (Lactuca sativa L.) is a suitable species for biofortification research based on genetic improvements. In this study, we aimed to select and obtain hybrid lettuce populations with high agronomic potential and biofortified carotenoid content. Ten lettuce lines registered in the “BG α Biofort” software were selected for hybridization. The crosses used to obtain the hybrids involved two strains rich in at least one of the pigments (chlorophyll and carotenoids), and 24 experimental hybrids were obtained. A total of 37 genotypes (strains, hybrids, and commercial cultivars) were evaluated using a randomized block design for agronomic variables and chlorophyll and carotenoid content. Hybrids 12 (UFU-189#3#4#1 × UFU MC BIOFORT 2) and 25 (UFU66#4#2 × UFU-189#3#4#1) had the potential to produce dual-purpose populations (yield and carotenoid biofortification). Hybrid 27 (UFU66#4#2 × UFU MC BIOFORT1) exhibited the best pigment balance. Thus, F2 hybrids 12, 25, and 27 should be obtained to produce new cultivars of biofortified red and green lettuce for curly, american, mini, and romaine lettuce segments. goal problems Thus essential Lactuca L.

RESUMO O excesso de sais na água e/ou no solo se destaca como um dos estresses que compromete o desenvolvimento das culturas, dentre elas o tomate cereja, sendo necessário o uso de estratégias que reduzam o efeito do estresse salino, como à aplicação foliar de peróxido de hidrogênio. Assim, o objetivo deste estudo foi avaliar o efeito da aplicação foliar de H2O2 sobre o teor de pigmentos fotossintéticos, crescimento e produção de tomate cereja sob salinidade da água de irrigação. O delineamento utilizado foi o de blocos casualizados, em esquema fatorial 5 × 5, sendo cinco valores de condutividade elétrica da água - CEa (0,3; 1,0; 1,7; 2,4 e 3,1 dS m-1) e cinco concentrações de peroxido de hidrogênio - H2O2 (0; 15; 30; 45 e 60 µM). A aplicação de peróxido de hidrogênio na concentração de 60 µM atenuou o efeito deletério do estresse salino no crescimento em altura de plantas e no número de folhas de tomate cereja até a CEa de 3,1 dS m-1.

ABSTRACT Excess of salts in water and/or soil stands out as one of the stresses that compromise the development of crops, including cherry tomato, requiring the use of strategies that reduce salt stress effects, such as foliar application of hydrogen peroxide. Thus, the objective of this study was to evaluate the effect of foliar application of H2O2 on the contents of photosynthetic pigments, growth, and production of cherry tomato under irrigation water salinity. The design used was randomized blocks, in a 5 × 5 factorial scheme, with five values of electrical conductivity of water - ECw (0.3, 1.0, 1.7, 2.4, and 3.1 dS m-1) and five concentrations of hydrogen peroxide - H2O2 (0, 15, 30, 45, and 60 μM). Application of hydrogen peroxide at concentration of 60 μM attenuated the deleterious effects of salt stress on the growth and number of leaves of cherry tomato up to ECw of 3.1 dS m-1. Hydrogen peroxide concentration of 45 μM increased root dry mass, synthesis of chlorophyll b and total chlorophyll under electrical conductivity of water of 0.3 dS m-1 and synthesis of chlorophyll a up to ECw of 0.8 dS m-1. Foliar application of 30 μM reduced the effects of salt stress on leaf, shoot and total dry mass accumulation up to ECw of 3.1 dS m-1. Electrical conductivity of water from 1.41 dS m-1 reduced the production of cherry tomato. andor or crops Thus HO H O H2O pigments salinity blocks scheme 0.3, 03 0 3 (0.3 10 1 1.0 17 7 1.7 24 2 4 2.4 31 3. m1 m 0, (0 15 6 μM. . μM) m1. 1. 0. m- 08 8 leaf 141 41 1.4 (0. 2.

Plectranthus amboinicus is an aromatic herb often used in traditional medicine due to its antimicrobial properties. Based on it, the present study aimed to assess the toxic, antioxidant and, antibacterial properties of P. amboinicus essential oil (EO) either separated or mixed into fish feed. The chemical composition of the EO was also investigated. All samples were prepared with over 50% of carvacrol. The results revealed that the EO is a weak antioxidant and highly toxic against Artemia salina, showing greater antibacterial activity than positive control of chloramphenicol and synergistic effects. The EO also presented high antimicrobial activity against Aeromonas hydrophila strains when free or feed-incorporated, thus being a promising product for the treatment of opportunistic infections in fish. it P (EO feed investigated 50 carvacrol salina effects feedincorporated, feedincorporated incorporated, incorporated feed-incorporated 5

RESUMO Em regiões áridas e semiáridas, a produção agrícola é desafiadora devido à escassez de água para irrigação, sendo comum o uso de água salobra. No entanto, o uso dessas águas afeta negativamente o crescimento e o desenvolvimento das culturas. Neste contexto, é essencial a busca por estratégias para amenizar os efeitos do estresse salino nas plantas. O objetivo desta pesquisa foi avaliar efeitos da aplicação foliar de H2O2 nas trocas gasosas, nos pigmentos fotossintéticos, na eficiência fotoquímica e no crescimento de plantas de tomate cereja em cultivo hidropônico com solução nutritiva salina. O experimento foi desenvolvido em casa de vegetação em Pombal-PB, utilizando o sistema hidropônico tipo técnica de fluxo laminar de nutriente. Os tratamentos foram distribuidos em esquema de parcelas subdivididas, onde os níveis de condutividade elétrica da solução nutritiva – CEsn (2, 1; 2,8; 3,5 e 4,2 dS m-1) foram considerados as parcelas e as cinco concentrações de H2O2 (0, 12, 24, 36 e 48 μM) como subparcelas, com seis repetições e duas plantas por parcela. A CEsn a partir de 2,1 dS m-1 reduziu as trocas gasosas, a eficiência fotoquímica, os pigrmentos fotossintéticos, o conteúdo relativo de água e o crescimento do tomate cereja.

ABSTRACT In arid and semi-arid regions, agricultural production is challenging due to the scarcity of water for irrigation, so brackish water is commonly used. However, the use of these waters negatively affects the growth and development of crops. In this context, it is essential to look for strategies to mitigate the effects of salt stress on plants. The objective of this study was to evaluate the effects of foliar application of H2O2 on gas exchange, photosynthetic pigments, photochemical efficiency, and growth of cherry tomato plants in hydroponic cultivation with saline nutrient solution. The experiment was carried out in a greenhouse in Pombal-PB, using a Nutrient Film Technique (NFT) hydroponic system. Treatments were distributed in a split-plot scheme, in which the levels of electrical conductivity of the nutrient solution - ECns (2.1, 2.8, 3.5, and 4.2 dS m-1) were considered the plots and the five concentrations of H2O2 (0, 12, 24, 36, and 48 μM) were considered the subplots, with six replicates and two plants per plot. ECns from 2.1 dS m-1 reduced gas exchange, photochemical efficiency, photosynthetic pigments, relative water content, and growth of cherry tomato. H2O2 at concentrations of 36 and 48 μM associated with saline nutrient solution of 2.1 dS m-1 stimulated plant height, growth, and chlorophyll b synthesis, respectively. Hydrogen peroxide alone did not affect gas exchange, chlorophyll fluorescence, photosynthetic pigments, and growth of cherry tomato. semiarid semi regions irrigation used However crops context HO H O H2O exchange pigments efficiency PombalPB, PombalPB Pombal PB, PB Pombal-PB NFT (NFT system splitplot split plot scheme 2.1, 21 2 1 (2.1 28 8 2.8 35 3 5 3.5 42 4 4. m1 m 0, 0 (0 12 24 subplots 2. m- content height synthesis respectively fluorescence (2. 3.

RESUMO As fontes hídricas do semiárido brasileiro comumente apresentam altos teores de sais dissolvidos em sua composição, destacando-se como um dos estresses abióticos que limita a expansão da fruticultura irrigada, principalmente de culturas sensíveis ao estresse salino como o maracujazeiro-azedo. Assim, a utilização de substâncias elicitoras, como prolina, pode ser uma alternativa eficaz para mitigar o estresse salino nas plantas. Nesse contexto, objetivouse com este trabalho avaliar os efeitos da aplicação foliar de prolina na fluorescência da clorofila, crescimento, qualidade e tolerância de maracujazeiro-azedo irrigados com águas salinas durante a fase de formação de mudas. A pesquisa foi conduzida no período de julho a outubro de 2022, em casa de vegetação em Campina Grande - PB, utilizando-se o delineamento inteiramente casualizado, em esquema fatorial 5 × 4, sendo cinco níveis de condutividade elétrica da água de irrigação CEa - (0,6; 1,2; 1,8; 2,4 e 3,0 dS m-1) e quatro concentrações de prolina (0, 5, 10 e 15 mM) com quatro repetições e duas plantas por parcela.

ABSTRACT Water sources in the Brazilian semi-arid region commonly contain high levels of dissolved salts in their composition, standing out as one of the abiotic stresses that limit the expansion of irrigated fruit growing, especially salt stress-sensitive crops such as sour passion fruit. Thus, the use of elicitors, such as proline, can be an effective alternative to mitigate salt stress in plants. In this context, the objective of this study was to evaluate the effects of foliar application of proline on chlorophyll fluorescence, growth, quality and tolerance of sour passion fruit irrigated with saline water during the seedling formation phase. The experiment was conducted from July to October 2022, under greenhouse conditions in Campina Grande, PB, Brazil, using a completely randomized design, in a 5 × 4 factorial scheme, with five levels of electrical conductivity of irrigation water - ECw (0.6, 1.2, 1.8, 2.4 and 3.0 dS m-1) and four concentrations of proline (0, 5, 10 and 15 mM), with four replicates and two plants per plot. Water salinity from 0.6 dS m-1 reduces the maximum fluorescence, variable fluorescence, quantum yield of photosystem II and growth of ‘BRS GA1’ sour passion fruit seedlings. Foliar application of proline at concentrations ranging from 6 to 8.05 mM increases the growth in plant height, stem diameter and leaf area of sour passion fruit seedlings. The sour passion fruit genotype ‘BRS GA1’ is sensitive to water salinity, with a salinity threshold level of 0.6 dS m-1 and a reduction per unit increase in electrical conductivity of 10.49%. semiarid semi arid composition growing stresssensitive Thus elicitors context fluorescence phase 2022 Grande PB Brazil design scheme 0.6, 06 0 (0.6 12 1 2 1.2 18 8 1.8 24 2. 30 3 3. m1 m 0, (0 mM, , mM) plot 0. m- BRS GA1 GA seedlings 805 05 8.0 height 1049 49 10.49% 202 (0. 1.

Abstract Despite the prevalence of substance use during pregnancy, studies focusing exclusively on Neonatal Intensive Care Units (NICU) admissions remain limited. This study investigates the impact of maternal use of tobacco, alcohol, and/or crack, on neonatal outcomes among infants admitted to three Brazilian NICUs. Additionally, the investigation explores the impact of substance use on DNA damage in newborns. Over a one-year period, data from 254 newborns were collected through medical records, accompanied by blood samples. Findings revealed that 16.1% of newborns had mothers reporting substance use during pregnancy. Significant associations were found between maternal substance use and adverse neonatal outcomes, including low birth weight, preterm birth, and sexually transmitted infections. Maternal variables linked to substance use encompassed non-white skin color, low education, non-masonry housing, lower income, diseases in other children, and fewer prenatal consultations. Notably, neonatal DNA damage showed no significant association with substance use. Our results underscore the substantial impact of maternal substance use on NICU-admitted infants, emphasizing the necessity for targeted interventions that address both neonatal health and maternal well-being, thereby underscoring the crucial role of comprehensive care in NICU settings. pregnancy (NICU limited tobacco alcohol andor or crack NICUs Additionally oneyear one year period 25 records samples 161 16 1 16.1 weight infections nonwhite non white color education nonmasonry masonry housing income children consultations Notably NICUadmitted wellbeing, wellbeing well being, being well-being settings 2 16.

ABSTRACT This study investigated the occurrence of mycotoxins in wet brewers’ grains (WBG) treated with salt (sodium chloride) and the intake, nutrient digestibility, and nitrogen use efficiency in lamb diets. Two experiments were conducted: first, WBG was distributed in plastic boxes and treated with no additive (control), sodium formate (3 g/kg of WBG), or three levels of salt—25, 30, and 35 g/kg of WBG. The WBG were stored at room temperature (17.7±4.6 ℃) for 27 days. In the second experiment, eight six-month-old male lambs were allotted to one of four total mixed ration (TMR) diets in a 4 × 4 double Latin square: 0, 10, 20, and 30% of WBG replacing corn silage and soybean meal. In the first experiment, the concentration of mycotoxins throughout the experiment was lower than the tolerance levels accepted by the European Community and Food and Drug Administration for animal feedstuffs. However, the control and sodium formate groups showed visual fungal development on the WBG surface from the sixth day and presented an unpleasant smell from day 12. In the salt treatments, fungal growth was observed on top of the WBG from day 12 and an unpleasant smell from day 15. Salt-treated WBG showed a lower pH than the control and sodium formate groups and decreased dry matter deterioration. In the second experiment, including up to 30% WBG in the TMR did not affect dry matter, organic matter, neutral detergent fiber, and acid detergent fiber intake or digestibility in lambs. However, the N digestibility and N use efficiency increased with WBG inclusion. These results suggest that salt can be used to increase the storage time of WBG up to 15 days and the inclusion of up to 30% WBG in TMR for lambs can improve N use efficiency without negatively affecting nutrient intake and digestibility. brewers (WBG chloride conducted control, , (control) 3 ( gkg g kg WBG, WBG) salt25, salt25 25, 25 salt—25 30 17.7±4.6 17746 17 7 6 (17.7±4. ℃ 2 sixmonthold six month old (TMR square 0 10 20 meal feedstuffs However treatments 1 Salttreated Salt deterioration (control salt2 salt—2 17.7±4. 1774 (17.7±4 salt— 17.7±4 177 (17.7± 17.7± (17.7 17.7 (17. 17.

Silver nanowires thin films have gained attention due to their excellent optical and electrical properties, being a potential material to be applied in optoelectronic devices as transparent conductive films, deposited on a substrate in a such way that forms a percolated network. We report the synthesis of silver nanowires with average length of 9.5 ± 0.4 µm and diameter of 75 ± 3 nm by a modified polyol method and fabrication of transparent and conductive thin films using a simple and low-cost technique as drop-casting. Additionally, we examined the influence of the drop-casting method in function of number of deposition cycles on the optical and electrical properties of the films through optical absorption and electrical resistance measurements using the two-point methodology. Increasing the number of silver nanowire deposition layers, the optical transmittance decreased from 97 (for one layer) to 60% (for five layers), and electrical resistance decreased from 940 ± 0.35 Ω for the 2-layer film to 32 ± 0.02 Ω, for the 5-layer film. Due to the electrical conductivity range of the produced silver nanowires films, we suggested their application in low-voltage circuits. network 95 9 5 9. 04 0 4 0. 7 lowcost low cost dropcasting. dropcasting drop casting. casting Additionally twopoint two point methodology layers layer 60 , layers) 94 035 35 0.3 2layer 2 002 02 0.0 5layer lowvoltage voltage circuits 6 03 00

This study investigated natural attenuation conducted in soil artificially contaminated with low-sulfur diesel oil, and to evaluate the corrosion of ASTM A36 carbon steel (A36) during the bioremediation process. Microbiological quantification of hydrocarbonoclastic bactéria (HCB) and heterotrophic bacteria (Aerobic and Anaerobic) was carried out at 7, 14, 28, 42 and 56 days. Corrosion rate was quantified according to the NACE-SP-07-75 standard using the gravimetric method. Morphological analysis was conducted through Scanning Electron Microscopy. Results indicated a significant reduction of 24.03% in oils and greases in the soil, along with a respirometric degradation of 11.10%. Soil contamination with diesel led to microbial growth, mainly of HCB, during diesel bioremediation; however, there was no impact on the corrosion rate of A36. Soil corrosivity with diesel was classified as low after 56 days of experiment. These findings show that natural attenuation is a method capable of bioremediating soil with diesel without impacting nearby steel structures. lowsulfur sulfur oil A A3 (A36 process HCB (HCB Aerobic Anaerobic 7 14 28 4 5 NACESP0775 NACESP NACE SP 07 75 NACE-SP-07-7 Microscopy 2403 24 03 24.03 1110 11 10 11.10% growth however experiment structures (A3 1 2 NACESP077 0 NACE-SP-07- 240 24.0 111 11.10 (A NACESP07 NACE-SP-07 24. 11.1 NACESP0 NACE-SP-0 11.

Abstract Plants used in traditional medicine offer an affordable new alternative in tissue repair therapy. This study aimed to evaluate the effectiveness of the 5% Rhizophora mangle cream compared to the 5% dexpanthenol cream in healing open surgical wounds on the upper eyelid. A total of 18 patients were submitted to the experiment and divided into 2 groups with 9 patients each who used topically and daily 5% dexpanthenol cream (control group) or 5% R.mangle cream (intervention group) for 7 days. Clinical, morphometric and histomorphometric analyses of wounds and surgical procedures for skin removal were performed. In the morphometric analysis, all wounds treated with R.mangle and dexpanthenol creams showed complete macroscopic scars, without inflammatory signs and infection free. The skin hydration values in pre and post application periods of the cream were 43.82 ± 43.93 and 62.12 ± 67.40 respectively. The histomorphometric study showed lower values of epithelium distance in R. mangle group and higher in dexpanthenol group with significant difference between groups (p < 0.05). The R.mangle 5% cream proved to be effective in healing wounds of human upper eyelid skin with a significant improvement in epithelization compared to dexpanthenol 5% cream. therapy 5 1 control Rmangle R intervention days Clinical performed analysis scars free 4382 43 82 43.8 4393 93 43.9 6212 62 12 62.1 6740 67 40 67.4 respectively p 0.05. 005 0.05 . 0 05 0.05) 438 4 8 43. 439 621 6 62. 674 67. 00 0.0 0.

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

RESUMO As inundações sem precedentes de abril a maio de 2024 no Rio Grande do Sul afetaram mais de 90% do estado, deslocando centenas de milhares de pessoas e causando 172 mortes. O fenômeno El Niño Oscilação Sul foi considerado importante para explicar a variabilidade nas chuvas observadas, consistente com pesquisas anteriores que mostram que eventos anteriores de fortes chuvas na área ocorreram durante anos de El Niño. As frentes frias que trazem chuvas permaneceram estacionadas no sul do Brasil, uma vez que não puderam se mover para o centro do Brasil devido ao bloqueio atmosférico com ar quente e seco e às temperaturas mais altas naquela região. A inundação em Porto Alegre foi desencadeada por fortes chuvas na Bacia do Guaíba, com acumulações superiores a 500 mm em 5 dias, levando a níveis recordes de 5,35 m em 5 de maio, valores mais altos que a enchente anterior, em 1941. Além do caráter extremo deste evento, isso contribuiu para os impactos significativos de enchentes em áreas vulneráveis da Região Metropolitana de Porto Alegre e municípios próximos. Isso mostra a necessidade de avaliar objetivamente o risco e reforçar a infraestrutura para inundações para aumentar a resiliente a esta e futuras enchentes, ainda mais extremas. 202 90 estado 17 mortes observadas região Guaíba 50 dias 535 35 5,3 anterior 1941 evento próximos extremas 20 9 1 53 3 5, 194 2 19
ABSTRACT The unprecedented 2024 April-May floods in the State of Rio Grande do Sul have affected over 90% of the state, displacing hundreds of thousand people and causing 171 deaths. The El Niño Southern Oscillation phenomenon was found to be important to explain the variability in the observed rainfall, consistent with previous research that show previous heavy rainfall events in the area occurred during El Niño years. Cold front fronts bringing rainfall remained stationary over southern Brazil, since they could not move into central Brazil because of atmospheric blocking with warm and dry air and highest temperatures in that region. The flood event in Porto Alegre was triggered by heavy rainfall over the Lake Guaíba Basin, with accumulated surpassing 500 mm in 5 days, leading to record high levels of 5,35 m on May 5, highest that the previous flood in 1941. In addition to the extreme nature of this event, this contributed to the significant impacts of flooding in vulnerable areas of the Porto Alegre Metropolitan Region and nearby municipalities. This highlights the need to objectively assess risk and reinforce flood infrastructure to increase resilience to this and future, even more extreme, floods. 202 AprilMay April 90 state 17 deaths years region Basin 50 days 535 35 5,3 1941 municipalities future 20 9 1 53 3 194 2 19

RESUMO O crisântemo (Dendranthema grandiflora) é a segunda planta ornamental mais produzida e comercializada no mundo. A medição da área foliar por métodos não destrutivos é fundamental para estudos sobre seu crescimento e produção. A estimativa da área foliar por dimensões lineares das folhas pode ser uma estratégia para este fim. O objetivo deste estudo foi encontrar equações alométricas para estimar a área foliar do crisântemo. Os modelos de regressão linear, linear sem intercepto, quadrático, cúbico, potência e exponencial foram utilizados para a análise. A escolha das equações foi baseada nos maiores coeficientes de determinação. O método não destrutivo por meio de modelos alométricos tem acurácia para estimar a área foliar (AF) do crisântemo a partir do produto entre o comprimento da folha (C) e a largura da folha (L). A AF do crisântemo pode ser estimada pela equação ŷ = 0,6611*CL0,9490 (C - comprimento da folha; L - largura da folha). Essa equação permitirá que pesquisadores e produtores determinem a área foliar de forma não destrutiva.

ABSTRACT Chrysanthemum (Dendranthema grandiflora) is the second most produced and commercialized ornamental plant in the world. Measuring leaf area through non-destructive methods is fundamental for studies on its growth and production. The estimation of leaf area by linear dimensions of the leaves can be a strategy for this purpose. The objective of this study was to find allometric equations to estimate the leaf area of chrysanthemum. The linear, linear without intercept, quadratic, cubic, power, and exponential regression models were used for the analysis. The choice of equations was based on the highest coefficients of determination. The non-destructive method using allometric models has accuracy for estimating the leaf area (LA) of chrysanthemum from the product between leaf length (L) and leaf width (W). The LA of chrysanthemum can be estimated using the equation ŷ = 0.6611*LW0.9490 (L - leaf length; W - leaf width). This equation will allow researchers and producers to determine leaf area non-destructively.
