ABSTRACT Soil saturated hydraulic conductivity (Ksat) and steady-state infiltration rate (SSIR) are essential and necessary soil properties for different geoscience applications. Values of these hydraulic properties for the Brazilian territory are difficult to access and are dispersed in research efforts carried out around the country. This study developed an easy-to-manipulate, freely accessible database of soil saturated hydraulic conductivity, comprising field and laboratory analyses, and steady-state infiltration rates for Brazilian soils. This database was named Ksat-SSIR-DB. One analysis of the Ksat-SSIR-DB aimed to evaluate its coverage in Brazilian territory and in different soil groups. Average values of these hydraulic properties were also presented for textural classes, with values compared to those reported in international literature, and for other groupings, such as soil class, land use class, and porosity class. The variability of Ksat data in these groupings and in their combinations were also analyzed. The Ksat-SSIR-DB showed broad national coverage, comprising a total of 2,579 records, corresponding to 409 sampling sites, with Ksat and/or SSIR data and other associated soil information. A significant difference was observed between Ksat values for the vast majority of Brazilian clayey and very clayey soils compared to soils from the same textural groups from temperate regions. The two groupings that presented the lowest variability in terms of Ksat standard deviation values were the combination of textural classes with soil classes at the second category level of SiBCS (Brazilian Soil Classification System), and porosity classes with soil classes at the second category level of SiBCS. The Ksat-SSIR-DB has enormous potential for developing and testing Ksat pedotransfer functions in Brazilian soils, serving as a reference source for different geoenvironmental applications and, in particular, for modeling land surface processes. It is open access and can be accessed at https://www.sgb.gov.br/ksat-ssir-dbbase-de-dados-de-condutividade-hidraulica-saturada-e-de-taxa-de-infiltracao-basica-emsolos-brasileiros, which also includes the python script for data analysis.

RESUMEN: Establecer técnicas de propagación que promuevan el rejuvenecimiento/revigorización de genotipos es fundamental para el rescate de árboles adultos del género Eucalyptus. El objetivo de este estudio fue evaluar la inducción de yemas y brotes epicórmicos en ramas podadas y el establecimiento, multiplicación, elongación y fidelidad genética de tres plantas seleccionadas de Eucalyptus pilularis de 44 años de edad. M1, M2 y M3 representan las plantas seleccionadas. M1 fue el mejor en número de yemas epicórmicas, número de brotes, baja tasa de oxidación del tejido y explantes que no responden. En la fase de establecimiento, M3 mostró baja contaminación, número de brotes y longitud de brotes. La emisión de brotes ocurrió para M3, y fue el único genotipo sometido a las demás fases (multiplicación, elongación y enraizamiento). En la fase de multiplicación, los mayores valores de vigor y longitud de brotes se encontraron en el subcultivo 15. La oxidación fenólica tuvo su mayor valor en el subcultivo 12, disminuyendo a partir del 13. El valor más alto para el número de brotes se encontró en el subcultivo 11. No se observó polimorfismo entre la planta seleccionada M3 y los brotes obtenidos en el subcultivo 15. En elongación, el uso de medio de cultivo que contenía 0,10 mg L-1 de BAP y 1,00 mg L-1 de ANA proporcionó las medias más bajas para la oxidación, y los más altos para vigor, número y longitud de brotes por explante. Se observó la emisión de raíces adventicias, demostrando que, a través de la micropropagación, era posible inducir la competencia para enraizar el material, incluso en una edad ontogenética avanzada.

SUMMARY: Establishing vegetative propagation techniques to promote the rejuvenation/reinvigoration of genotypes is essential for the rescue of adult trees of the Eucalyptus genus used in species and provenance tests. The aim of this study was to evaluate the induction of epicormic buds and shoots in pruned branches and the in vitro establishment, multiplication, genetic fidelity, and elongation of three 44-year-old Eucalyptus pilularis selected plants. M1, M2 and M3 represent selected plants. M1 produced the highest number of epicormic buds, number of shoots, and with the lowest rate of tissue oxidation and non-reactive explants. In the establishment stage, M3 exhibited the lowest contamination percentage, number of shoots, and shoot length. The emission of shoots occurred only for M3, and it was the unique genotype subjected to the other stages (i.e. multiplication, elongation, and rooting). In the multiplication stage, the highest vigour and shoot length values of were found in the 15th subculture. Phenolic oxidation had its highest value in the 12th subculture, decreasing from the 13th. The highest value for number of shoots was found in the 11th subculture. No polymorphism was observed in the selected plant (M3) and the clonal plants obtained in the 15th subculture. For shoots elongation, the use of culture medium containing 0.10 mg L-1 BAP and 1.00 mg L-1 NAA provided the lowest means for oxidation, and the highest for vigour, number, and length of shoots. The emission of adventitious roots was observed, demonstrating that, through micropropagation, it was possible to induce the competence to root the material, even at an advanced ontogenetic age.

ABSTRACT Objective: to assess the effect of implementing a quality improvement project on the process of pressure injury prevention in an adult Intensive Care Unit. Method: a quality improvement project for the pressure injury prevention process was carried out in an adult Intensive Care Unit of a public hospital from November 2022 to July 2023. It was developed following the steps of an improvement cycle. The quality level of pressure injury prevention was measured before and after the interventions, using six quality criteria. Data collection for the first assessment was conducted in March 2023, retrospectively, referring to November and December 2022 and January 2023. Quality reassessment occurred in July 2023, also retrospectively, referring to April, May, and June 2023. Interventions included changes in records related to assistance in pressure injury prevention and education/awareness of the team on pressure injury prevention. Results: the initial quality assessment showed that the compliance level of pressure injury prevention was low, with virtually all criteria showing rates below 50%. After the interventions, there was an increase in compliance with almost all criteria. Conclusion: the use of a quality improvement project enabled the improvement of the pressure injury prevention process and contributed to the scientific community by corroborating the effectiveness of these projects in implementing pressure injury prevention programs, as well as prompting reflection on the multifactorial nature involved in this preventive process.

ABSTRACT Irrigated areas have expanded globally to support the increasing population and mitigate the impacts of climate change and variability. The crop water balance accounting in the root zone estimates soil water deficits by considering water inputs and outputs that impact crop yield. In this study, we developed the CropWaterBalance R-package to assist users in irrigation scheduling. The package offers functionalities for estimating the reference evapotranspiration through various methods and comparing their performances. By incorporating user-provided management-allowed depletions, the package calculates several agrometeorological parameters including crop evapotranspiration rates, soil water deficit in the root zone, and water stress coefficient. The package also provides recommendations for irrigation timing and net irrigation depth. variability yield study Rpackage R scheduling performances userprovided user provided managementallowed management allowed depletions rates coefficient depth

ABSTRACT The standardized precipitation (SPI) and standardized precipitation-evapotranspiration (SPEI) indices are important tools for monitoring drought events, but the low density of weather station networks limits their use in many regions. To address this issue, we developed the PowerSDI R-package, which calculates these two indices using gridded-data from the NASA-POWER project (NASA-SPI and NASA-SPEI). Different from other packages, the PowerSDI package has two modes: the scientific, and the operational. In the scientific mode, the users may assess the quality of the indices estimates through their agreement with a reference/observed series and through the evaluation of how well these estimates meet the conceptual assumptions required for calculating both SPI and SPEI. This evaluation is based on measure of accuracy (e.g., Willmott index of agreement), goodness-of-fit tests (e.g., Anderson-Darling), and normality tests (e.g., Shapiro-Wilk’s test), which are calculated by the ScientSDI.R, Reference.R, and Accuracy.R functions. In the operational mode, users can calculate both indices routinely using the OperatSDI.R function. The package also uses a quasi-weekly time scale, allowing for index calculations four times a month. The OperatSDI.R enables users to download NASA-POWER data for all available period or only for the quasi-week they intend to monitor (reducing the function’s running time). In short, the PowerSDI facilitates the routine use of these two widely used drought indices and, unlike others existing software, it provides a solid scientific basis for using NASA-POWER data in drought monitoring systems, which can help improve drought preparedness and response efforts worldwide. The package is freely available at two repositories: Github (https://github.com/gabrielblain/PowerSDI), and CRAN (https://CRAN.R-project.org/package=PowerSDI).

ABSTRACT Littoral cell angioma is an extremely rare splenic vascular tumor originating from the cells lining the splenic red pulp sinuses. Approximately 150 cases of littoral cell angioma have been reported since 1991. Its clinical manifestation is usually asymptomatic and is mostly diagnosed as an incidental finding through abdominal imaging. Herein, we present a case of littoral cell angioma in a 41-year-old woman with no previous comorbidities, which initially presented as a nonspecific splenic lesion diagnosed on imaging in the emergency room. The patient was treated through laparoscopic intervention. sinuses 15 1991 Herein 41yearold yearold 41 year old comorbidities room intervention 1 199 4 19

ABSTRACT The standardized precipitation-evapotranspiration index (SPEI) is a widely used probability-based method that categorizes drought and wet events based on their expected frequency of occurrence. Regional frequency analysis based on L-moments (RFA-Lmom) is often employed to enhance probabilistic assessments of extreme hydrological data, which typically assume positive values. This study investigated whether applying the RFA-Lmom regionalization technique to the difference between precipitation and potential evapotranspiration (P-PE), the input variable for SPEI, can improve the index’s ability to meet the normality assumption. We conducted analyses using Monte Carlo experiments, accounting for distinct climate conditions worldwide, and a case study in the watershed of the Piracicaba, Capivari and Jundiaí rivers, situated in the states of São Paulo and Minas Gerais, Brazil. In this region, P-PE frequency distributions may exhibit negative and positive sample means. Our findings suggested that modifying the RFA-Lmom method by replacing the L-moment ratio L-CV with the L-moment scale measure and using an additive model (instead of the original multiplicative procedure) for SPEI calculation allows the application of this regionalization technique to P-PE amounts. This adapted RFA-Lmom consistently enhanced the ability of SPEI frequency distributions to meet their normality assumption, thereby improving the quality of drought assessments based on this standardized index. precipitationevapotranspiration (SPEI probabilitybased probability occurrence Lmoments L moments RFALmom RFA Lmom (RFA-Lmom data values PPE, PPE P PE , (P-PE) indexs s assumption experiments worldwide Piracicaba rivers Gerais Brazil region means Lmoment moment LCV CV instead procedure amounts (P-PE

RESUMO Finos de carvão vegetal são coprodutos da carbonização da madeira, indesejados por diminuir o rendimento gravimétrico em carvão vegetal. São produzidos devido ao processo de carbonização, durante o armazenamento e transporte do carvão vegetal. A pelletização de finos aumenta a densidade energética, produzindo um combustível homogêneo e com menor teor de umidade, possibilitando a queima em equipamentos com alta eficiência energética, além de propriedades desejáveis em produtos energéticos como alto teor de carbono fixo e baixo teor de umidade. Este estudo avaliou o efeito do teor de umidade e do tempo de secagem na produção de black pellets a partir de finos de carvão vegetal ligados com amido de arroz (Oryza sativa) nas características físico-químicas e mecânicas. Os black pellets foram produzidos utilizando duas proporções de água (10 ou 20%) e tempo de secagem de 4 ou 6 horas. Os black pellets foram avaliados quanto à análise química imediata, composição elementar, teor de umidade, tamanho, densidade aparente, poder calorífico e densidade energética. A adição de água não afetou o teor de voláteis, cinzas e carbono fixo, enquanto o tratamento com adição de 20% de água e quatro horas de secagem apresentou maior teor de umidade (3,34%). A adição de água permitiu melhor condução de calor e disposição das partículas, produzindo pellets com durabilidade superior a 98%. A melhor disposição promovida pela adição de 20% de água também aumentou a densidade dos pellets, resultando em maior densidade energética. Os black pellets podem ser considerados uma boa alternativa para aquecimento residencial, com tratamento T3 (20% de umidade - 4h de secagem) apresentando elevada densidade energética e melhor desempenho em termos de propriedades desejáveis para utilização e comercialização de acordo com a norma EN 14961-6. madeira Oryza sativa físicoquímicas físico químicas mecânicas 10 (1 20 imediata elementar tamanho aparente voláteis 3,34%. 334 3,34% . 3 34 (3,34%) partículas 98 98% residencial T (20 h 149616. 149616 14961 6. 14961-6 1 ( 2 33 3,34 (3,34% 9 (2 1496 14961- 3,3 (3,34 149 3, (3,3 14 (3, (3

ABSTRACT Charcoal fines are co-products of the wood carbonization process, unwanted because they reduce the gravimetric yield of the main product, charcoal. It can be produced due to the carbonization process, during the storage and transport of charcoal. Pelletizing charcoal fines increases the energy density of this material, producing a homogeneous fuel with lower moisture content, enabling burning in equipment with high energy efficiency, in addition to desirable properties in energy products such as high fixed carbon content and low moisture content. This study evaluated the effect of moisture content and drying time on the production of black pellets from charcoal fines bound with rice starch (Oryza sativa) on the physicochemical and mechanical characteristics. Black pellets were produced using two proportions of water (10 or 20%) and a drying time of 4 or 6 hours. Black pellets were evaluated for their proximate analysis, elemental composition, moisture content, size, apparent density, calorific value and energy density. The addition of water did not affect the content of volatile matter, ash, and fixed carbon, while the treatment with addition of 20% water and four hours of drying showed a higher moisture content (3.34%). The addition of water allowed for better heat conduction and particle arrangement, producing pellets with a durability greater than 98%. The better arrangement promoted by the addition of 20% water also increased the density of the pellets, resulting in greater energy density. Black pellets can be considered an alternative for residential heating, with T3 treatment (20% - 4h) with a high energy density and better performance in terms of desirable properties for use and commercialization according to the standard EN 14961-6. coproducts co process product material efficiency Oryza sativa characteristics 10 (1 20 analysis composition size matter ash 3.34%. 334 3.34% . 3 34 (3.34%) 98 98% heating T (20 4h h 149616. 149616 14961 6. 14961-6 1 ( 2 33 3.34 (3.34% 9 (2 1496 14961- 3.3 (3.34 149 3.

Abstract Objective The present study evaluated the profile of germline mutations present in patients who underwent genetic counseling for risk assessment for breast cancer (BC), ovarian cancer (OC), and endometrial cancer (EC) with a possible hereditary pattern. Methods Medical records of 382 patients who underwent genetic counseling after signing an informed consent form were analyzed. A total of 55.76% of patients (213/382) were symptomatic (personal history of cancer), and 44.24% (169/382) were asymptomatic (absence of the disease). The variables analyzed were age, sex, place of birth, personal or family history of BC, OC, EC, as well as other types of cancer associated with hereditary syndromes. The Human Genome Variation Society (HGVS) nomenclature guidelines were used to name the variants, and their biological significance was determined by comparing 11 databases. Results We identified 53 distinct mutations: 29 pathogenic variants, 13 variants of undetermined significance (VUS), and 11 benign. The most frequent mutations were BRCA1 c.470_471delCT, BRCA1 c.4675 + 1G > T, and BRCA2 c.2T> G. Furthermore, 21 variants appear to have been described for the first time in Brazil. In addition to BRCA1/2 mutations, variants in other genes related to hereditary syndromes that predispose to gynecological cancers were found. Conclusion This study allowed a deeper understanding of the main mutations identified in families in the state of Minas Gerais and demonstrates the need to assess the family history of non-gynecological cancer for risk assessment of BC, OC, and EC. Moreover, it is an effort that contributes to population studies to evaluate the cancer risk mutation profile in Brazil.

Resumo Objetivo O presente estudo avaliou o perfil de mutações germinativas presentes em pacientes submetidas a aconselhamento genético para avaliação de risco para câncer de mama (CM), câncer de ovário (OC) e câncer de endométrio (CE) com possível padrão hereditário. Métodos Foram analisados os prontuários de 382 pacientes que realizaram aconselhamento genético após consentimento informado. Um total de 55,76% dos pacientes (213/382) eram sintomáticos (história pessoal de câncer), e 44,24% (169/382) eram assintomáticos (ausência da doença). As variáveis analisadas foram idade, sexo, naturalidade, história pessoal ou familiar de CM, OC, CE bem como outros tipos de câncer associados a síndromes hereditárias. As diretrizes de nomenclatura da Human Genome Variation Society (HGVS) foram usadas para nomear as variantes e seu significado biológico foi determinado pela comparação de 11 bancos de dados. Resultados Identificamos 53 mutações distintas: 29 variantes patogênicas, 13 variantes de significado indeterminado e 11 benignas. As mutações mais frequentes foram BRCA1 c.470_471delCT, BRCA1 c.4675 + 1G > T e BRCA2 c.2T > G. Além disso, 21 variantes parecem ter sido descritas pela primeira vez no Brasil. Além das mutações BRCA1/2, foram encontradas variantes em outros genes relacionados a síndromes hereditárias que predispõem a cânceres ginecológicos. Conclusão Este estudo permitiu conhecer melhor as principais mutações identificadas nas famílias do estado de Minas Gerais e demonstra a necessidade de avaliar a história familiar de câncer não ginecológico para avaliação do risco de CM, OC e CE. Além disso, é um esforço que contribui com estudos populacionais para avaliar o perfil de mutações de risco para câncer no Brasil.

ABSTRACT Objective: to analyze the challenges found in nurse-managers' work in the Brazilian and Portuguese hospital contexts. Method: a mixed-methods research study with a sequential explanatory approach, carried out between March 2019 and March 2020 with nurse-managers from four hospitals. The study was initiated with the quantitative stage, applying a survey to 143 participants and analyzing the data by means of analytical and inferential statistics. The qualitative stage was carried out with 71 of these participants using interviews, in order to understand the challenges inherent to this job, and the data were submitted to content analysis. Integration of the findings was performed through data connection. Results: in the quantitative stage, the results evidenced that the managerial activities carried out by nurses by scenario included planning, people management, management of care processes, management of materials, quality management and leadership, with higher mean values for the first four. The qualitative stage allowed deepening the previous findings, contrasting invisibility of the planning, confirming people management as the common challenge to the realities, explaining the mean values in the national and Portuguese scopes. Integration of the findings detailed the relevance of the conflicts and the deficit of professionals in people management and leadership. Conclusion: managing people, care processes and materials are challenges for nurses in hospital management in both countries. Nurses lack structural support and ongoing training for better management and improvement of planning and leadership.
