A pesquisa foi desenvolvida para avaliar o desempenho, a morfometria duodenal e as alterações histopatológicas do fígado de frangos de corte, alimentados com dietas contendo diferentes níveis de ...selênio (0,5; 1,1; 1,7; 2,3; 2,9 e 3,5ppm de Se/kg de ração), criados no período de 1 a 21 dias de idade, em condições de estresse calórico. As aves receberam dietas isonutritivas à base de milho e farelo de soja, formuladas para atender as exigências nutricionais, exceto para o selênio. A partir de uma dieta basal foi feita a suplementação do selênio, com o uso de selenometionina (Sel-Plex®). Setecentos e vinte pintos da linhagem Ross 308, mistos, foram utilizados em delineamento de blocos casualizados, com seis tratamentos e seis repetições com vinte aves por unidade experimental. O ambiente interno dos galpões foi avaliado com base no Índice de Temperatura de Globo Negro e Umidade(ITGU),no Índice de Temperatura e Umidade(ITU)e Temperatura Efetiva(TE). O uso da suplementação de selênio orgânico na alimentação de frangos de corte melhora a conversão alimentar, mas, não interfere nos parâmetros comprimento de cripta e altura de vilosidade e não promove reação inflamatória no fígado destes, nos níveis testados.
The research was conducted to evaluate the performance, duodenal morphology and histopathological changes in the liver of broilers fed diets containing different levels of selenium (0.5, 1.1, 1.7, 2.3, 2, 9 and 3.5ppm Se / kg diet), created in the period 1-21 days old, under heat stress conditions. The birds were isonutritives diets based on corn and soybean meal, formulated to meet the nutritional requirements, except for selenium. From a basic diet supplementation of selenium was taken, such as use of selenomethionine (Sel - Plex®). Seven hundred and twenty chicks of mixed lineage Ross 308, were used in a randomized complete block design with six treatments and six replicates of twenty birds each. The internal environment of the sheds was evaluated based on the Temperature Index Black Globe Humidity (BGT), the Temperature and Humidity Index (THI) and Effective Temperature (ET). The use of organic selenium supplementation in the diet of broilers improves feed conversion, but does not interfere in the length parameter crypt and villus height and does not promote inflammation in the liver of these, in both levels.
Abstract The objective of this study was to prepare three donkey milk yoghurt formulations mixed with goat, cow and buffalo milk. The formulations were developed with 50% donkey milk and 50% cow, ...buffalo or goat milk. Concentrated mango pulp was added for flavouring. An evaluation was performed on the chemical composition of each milk sample and the formulated yoghurts. The donkey milk showed the lowest values for fat, protein, casein, total solids and non-fat solids. In turn, goat milk reached higher levels of fat and total solids. Furthermore, buffalo milk stood out with the highest values of protein and non-fat solids. Yoghurt made with donkey and buffalo milk showed higher concentrations of protein, lactose, total solids and non-fat solids. In contrast, the yoghurt that contained donkey and cow milk in its formulation obtained a higher fat percentage and a lower percentage of lactose, total solids and non-fat solids. The low content of fat and total solids in donkey milk, in addition to the structure of the casein micelles and small fat globules favor low consistency in fermented products. Thus, mixing donkey milk with milks from other animal species can result in better chemical composition and better consistency.
O objetivo deste estudo foi identificar sinais de burnout na enfermagem na literatu-ra científica. Trata-se de um estudo de revisão integrativa da literatura utilizando a sigla PICO para esclarecer a ...questão norteadora: Existem evidências científicas para a ocorrência da síndro-me de burnout entre profissionais de enfermagem? Foram utilizadas como bases de da-dos o Institute for Scientific Information Web of Science, o PubMed e a Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS). Foram esclarecidos 291 artigos, dos quais foram incluídos 4 artigos. A alocação de tempo foi entre 2020 e 2022. Em termos de idio-ma, todos os artigos foram publicados em inglês. Com base na análise dos resultados de todos os estudos, alguns fatores foram associados ao desenvolvimento da síndrome de exaustão dos enfermeiros, a saber: feminilidade, experiência profissional, idade e cargo do enfermeiro, carga horária excessiva nas instituições de saúde e no domicílio, sentimento de estresse, desvalorizado trabalho e remuneração insuficiente, conflitos com funcionários, falta de apoio social, conflitos com outros enfermeiros e médicos. Com base nos resultados desses estudos, fica claro que é necessário criar estratégias para reduzir o estresse no ambiente de trabalho, para compreender e minimizar o seu impacto na vida das pessoas.

Nas Ci?ncias Sociais o campo da avalia??o institucional ocupa uma posi??o desprivilegiada, pois as pesquisas avaliativas desenvolvidas t?m frequentemente se debru?ado sobre a avalia??o de pol?ticas/programas. A avalia??o das institui??es p?blicas, em termos mais amplos, apenas tem alcan?ado certo espa?o na literatura educacional e, em alguma medida, nos estudos organizacionais. O problema ? que a primeira perspectiva, pela sua pr?pria natureza, pensa sobre um modelo espec?fico de institui??es- as universidades, enquanto que a segunda ainda que abarque um gama maior de tipos institucionais, t?m assumido uma postura essencialmente ?gerencialista?. A pergunta norteadora dessa pesquisa ?: a ENAP ? uma institui??o eficaz? O desafio ?, a partir das ferramentas te?ricas e metodol?gicas utilizadas pela avalia??o de pol?ticas e pela avalia??o das institui??es, sobretudo as educacionais, avaliar a Escola Nacional de Administra??o P?blica- ENAP, uma Escola de governo voltada oficialmente ? forma??o e qualifica??o da alta burocracia p?blica nacional. Para tanto, foram criadas dimens?es institucionais (carater?sticas organizacionais, gest?o administrativa, condi??es materiais, recursos humanos e dimens?o educacional) e elencadas quest?es a serem respondidas para cada uma delas. Esse trabalho contou com densa an?lise documental e entrevista estruturada com gestores da institui??o avaliada.
The field of institutional assessment occupies an unprivileged position in the Social Sciences, since evaluative researches have often focused on the assessment of policies/programs. The assessment of public institutions in a wider sense has achieved some recognition only in the educational literature, and to some degree in organizational studies. An issue with the former would be that it, due to its own nature, reflects upon a specific model of institution (the university), whereas the latter, despite including a wider range of institution types, have adopted an essentially managerialist approach. The guiding question for this research is: is ENAP an effective institution? This thesis deals with the challenge of assessing, with the use of the theoretical and methodological tools involved in the evaluation of policies and institutions (especially educational ones), the Escola Nacional de Administra??o P?blica (ENAP), a Escola de Governo (literally ?government school?) whose official goal is to train the upper echelons of the country?s public bureaucracy. To accomplish this, institutional dimensions?organizational characteristics, administrative management, material conditions, human resources, and educational dimension?were created, and questions relating to each of them were posed and answered. This research counted on dense documentary analysis and structured interview with managers of the evaluated instruction.

The managerial reform of the Brazilian state, implemented since 1995, has reinvigorated the discussion about the need for qualification of public bureaucracy so that the professional qualification of civil servants in all spheres of government, has been occupying a prominent position in the national and state politics. In summary, the argument was about the lack of qualification of the servers, that to made difficult the process of changing the government, because the reconfiguration of the state would need a well-trained staff, capable of undertaking the guidelines formulated by the reform. Amid the necessity for training of the existing bureaucracy and even training of new staff, the figure of the School of Government to stood out, institute generally responsible for train professionals for the public sector, in order to provide the improvement of government performance. Initially, the government schools were restricted to the federal government, but quickly were extended to the state. This research is devoted to analyze one of its state examples, the ESPEP (Escola do Serviço Público do Estado da Paraíba). The purpose is to present the School and reflect how it relates with the assumptions of management reform in Brazil
A reforma gerencial do Estado brasileiro, implantada a partir de 1995, revigorou a discussão sobre a necessidade de qualificação da burocracia pública de modo que a qualificação profissional dos servidores públicos, em todas as esferas de governo, vem ocupando posição relevante na agenda política nacional e estadual. Em síntese, o argumento utilizado era o de que a falta de qualificação dos servidores dificultava o processo de mudança da administração pública, já que a reconfiguração do Estado necessitaria de um quadro de pessoal bem formado, com capacidade de empreender as diretrizes formuladas pela reforma. Em meio à necessidade de capacitação da burocracia existente e mesmo formação de novos quadros, ganhou destaque a figura da Escola de Governo, instituto geralmente responsável por treinar, capacitar e até formar profissionais para o setor público, a fim de proporcionar a melhoria do desempenho governamental. Inicialmente, as Escolas de governo se restringiram à esfera federal, mas logo se estenderam à estadual. Essa pesquisa dedica-se à análise de um de seus exemplos estaduais, a ESPEP- Escola do Serviço Público do Estado da Paraíba. O objetivo é apresentar a Escola e refletir em que medida ela se relaciona, ou não, com os pressupostos da reforma gerencial brasileira.
Este artigo objetivou analisar a concepção dos funcionários de uma instituição financeira em relação à importância da formação do pedagogo para atuação nos ambientes empresariais. Para base teórica, ...utilizamos autores como Libâneo (2002), Pimenta (1999), Gonçalves e Donatoni (2007), Ribeiro (2003) e Pascoal (2007). A pesquisa delineou-se na modalidade de estudo de caso, numa instituição financeira, participando 31 funcionários que responderam a um questionário virtual, com perguntas abertas e fechadas. As análises revelaram que os colaboradores não conhecem as atribuições específicas do pedagogo no ambiente empresarial e não atribuem importância à formação acadêmica para atuação nas funções específicas do pedagogo.
The yellow passion fruit (Passiflora edulis f. flavicarpa Degener) crops have been gaining notoriety in Brazil, whose cultivation extends to almost all regions. The aim of this study was to evaluate ...the growth of yellow passion fruit seedlings in response to the interaction between substrate composition and irrigation water salinity levels. The experimental trial was installed in a randomized block design, with a factorial scheme (3x6) consisting of two factors: three levels of salinity and six types of substrates, distributed in four replications, each plot consisting of a polyethylene bag composed of two plants. The factor levels of salinity, electrical conductivity: 0.3, 1.2 and 2.1 dSm-1 did not influence the physiological growth and development of the seedlings, the substrates resulted in statistically significant effects, the cattle manure presented the highest percentage in levels of physiological growth and development of the plant.
Water deficit is a type of abiotic stress that often limits seed germination, causing oxidative stress, cellular damage and physiological quality reduction. However, brassinosteroids regulate several ...biochemical and physiological processes in plants, reducing the oxidative stress caused by abiotic stresses, such as water deficit. The present study aimed to evaluate the contributions of 24-epibrassinolide (EBR) on the root anatomy and antioxidant enzymes as well as the possible interference of EBR on the oxidative stress, germination and biomass of soybean seedlings subjected to water deficit. The experiment had a factorial design, with the factors completely randomized, and two osmotic potentials (0.0 and − 0.3 MPa, as the control and water deficit, respectively) and three levels of brassinosteroids (0, 50 and 100 nM EBR). Soybean seedlings subjected to water deficit presented reductions of the root epidermis (RET), root endodermis (RDT), root cortex (RCT), vascular cylinder (VCD) and root metaxylem (RMD); however, the application of 100 nM brassinosteroids promoted increases in these values of 21, 12, 15, 38 and 15%, respectively, compared with water deficit + 0 nM brassinosteroids. In relation to antioxidant enzymes, the treatment with 100 nM brassinosteroids induced an increase in all of the enzymes evaluated. This study revealed that brassinosteroids promoted an increase in the germination, length and dry matter of soybean seedlings, and these results were explained by the increments in the root anatomy, particularly of the RET, RDT, RCT, VCD and RMD. Reductions in the concentrations of reactive oxygen species (superoxide and hydrogen peroxide) and membrane damage (malondialdehyde and electrolyte leakage) were intrinsically related to the higher activities of antioxidant enzymes (superoxide dismutase, catalase, ascorbate peroxidase and peroxidase), confirming the benefits of brassinosteroids on the antioxidant system. Moreover, 100 nM brassinosteroids resulted in a better dose–response in soybean seedlings exposed to water deficit.
