Morphophysiology of the passion fruit ‘BRS Rubi do Cerrado’ irrigated with saline waters and nitrogen fertilization

This study aimed to evaluate the gas exchanges and growth of the purple passion fruit cultivar ‘BRS Rubi do Cerrado’ as a function of the salinity levels of the irrigation water and nitrogen fertilization. The research was conducted in pots adapted as drainage lysimeters, placed within a plant nursery, using a Regolithic Neosol of sandy texture, in the municipality of Pombal-PB, Brazil. A randomized block design was used, testing five levels of electrical conductivity of irrigation water (0.3, 1.1, 1.9, 2.7, and 3.5 dS m-1) associated with four doses of nitrogen (50, 75, 100, and 125% of the recommendation). The irrigation water salinity above 0.3 dS m-1 compromised the leaf area and the relative water content of the purple passion fruit ‘BRS Rubi do Cerrado’. High doses of nitrogen enhance the deleterious effects of irrigation water salinity on stomatal conductance, transpiration, internal CO2 concentration, CO2 assimilation rate, number of leaves, stem diameter, and height of purple passion fruit plants. When waters with salinity levels of up to 1.3 dS m-1 are used, the dose of 125 mg of N kg-1 of soil is recommendation for providing increases in the CO2 assimilation rate of the purple passion fruit ‘BRS Rubi do Cerrado’ at 70 days after sowing (DAS). Water salinity increases electrolyte leakage, regardless of nitrogen doses.This study aimed to evaluate the gas exchanges and growth of the purple passion fruit cultivar ‘BRS Rubi do Cerrado’ as a function of the salinity levels of the irrigation water and nitrogen fertilization.

Liderança do enfermeiro nos serviços de urgencia e emergencia: revisão integrativa / Nursing leadership in urgency and emergency services: integrative review

Objetivo: Analisar as evidências científicas acerca da liderança do enfermeiro nos serviços de urência e emergência. Metodologia: Revisão integrativa com pesquisa de estudos primários realizados nas bases de dados ScientificElectronic Library Online (SciELO), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) e Base de Dados de Enfermagem (BDENF), abrangendo os estudos publicados entre janeiro de 2013 a fevereiro 2018. Resultados: A amostra final constitui 11 publicações, agrupadas em duas categorias a saber: Estudos com foco na liderança do enfermeiro nos serviços de urgência e emergência e Estudos com foco na liderança de enfermagem. Conclusão: Verificou-se a necessidade de aprimoramento do enfermeiro na habilidade de liderança. Sendo uma estratégia de suma importância para desenvolvimento profissional, visto que esta é uma habilidade requerida por muitas instituições.

Análise de desempenho dos campeões da maratona internacional de São Paulo

Objetivo: Analisar o tempo de prova, idade e diferença de desempenho dos atletas campeões da Maratona Internacional de São Paulo em razão ao sexo biológico e classificação por continente. Além de verificar taxa de vencedores por países e continentes. Materiais e Métodos: A amostra foi integrada por dados secundários disponíveis em web referente a Maratona Internacional de São Paulo, sendo analisado as edições entre 1995 e 2022. Utilizando tratamento estatístico descritivo e inferencial por meio dos softwares Excel 2021 e JASP 0.16.4, sendo utilizado os testes de Shapiro-Wilk, Teste de Levene e Anova Fatorial 2x2. Resultados: Foi observado o tempo médio no sexo biológico masculino de 02:15:43 ±00:02:13 e no sexo biológico feminino 02:39:27 ±00:03:23 a diferença de desempenho entre sexo biológico foi de 17%. O teste de Anova Fatorial indicou efeito estatisticamente na variável tempo de prova no fator sexo a nível de significância p<0.01 com tamanho de efeito η2 0.941 e classificação a nível de significância p<0.05 com tamanho de efeito η2 0.006, na variável idade no fator classificação foi observado efeito estatístico com nível de significância p<0.05 com tamanho de efeito η2 0.122. Conclusão: Atletas do continente apresentaram maior número de vitórias, além de serem mais jovens e com melhores resultados, o tempo de prova feminino foi reduzido assim como a diferença de desempenho entre sexo biológico

Optimization of Extraction Method of Anthocyanins from Red Cabbage

Among the vegetables that stand out for their high concentration of anthocyanins, red cabbage appears as one of the most-used sources of these pigments in food production and it is considered a suitable raw material for the extraction of natural dye. Therefore, the objective was to carry out the production of natural extracts from red cabbage, under different conditions, varying the solvent, type of pre-treatment, pH range, and processing temperature during the concentration of the extracts. The anthocyanins were extracted from red cabbage using the following solvents: distilled water, 25% ethyl alcohol, and 70% ethyl alcohol. The raw material was divided into two groups, the first was subjected to a drying pre-treatment at 70 °C for 1 h and for the second group, the extraction was performed with the raw material in natura. Two pH ranges of 4.0 and 6.0 and extraction temperatures of 25 °C and 75 °C were used in the extracts, resulting in 24 formulations. The extracts obtained were analyzed for colorimetric parameters and anthocyanins. The results of anthocyanins show that the methodology that uses 25% alcohol, pH 4.0, and processing temperature of 25 °C produces a reddish extract and better results in the extraction, presenting average values of 191.37 mg/100 g of anthocyanins, being 74% higher compared to the highest values obtained in the other extracts where the same raw material was used and the solvents differed
