Interação entre a equipe de enfermagem e a gestante com diagnóstico de pré-eclâmpsia

The objective of this exploratory descriptive study with a qualitative approach was to analyze the perception of the nursing team and the pregnant women hospitalized with pre-eclampsia regarding the interactive process occurring in the care relationship. Data were collected by semi-structured interview with twenty nursing professionals that work in the high-risk ward and ten pregnant women with the diagnosis of pre-eclampsia. The discourses were analyzed using the content analysis method, in the modality of thematic identification. Three categories were identified that describe the perception of the interaction by the nursing professionals: recognizing the needs of the hospitalized pregnant woman, understanding the woman with pre-eclampsia, and presenting difficulties in the interactive process. With regards to the pregnant women, four categories emerged: recognizing the clinical care, feeling the lack of information, experiencing feelings during the hospitalization, and envisioning the interaction process. The meaning of the discourses was analyzed according to the principles of symbolic interactionism. The results indicate that both, the nursing professionals and the pregnant women, have a limited perception of their interaction, suggesting a need for further reflection about this reality in the health service units and in the nursing education environment

Influência da interação fósforo disponível × fitase da dieta sobre o desempenho, os níveis plasmáticos de fósforo e os parâmetros ósseos de poedeiras comerciais

Dois experimentos foram realizados para avaliar a interação fósforo disponível (Pd) × fitase (UF) da dieta sobre o desempenho, os níveis plasmáticos de fósforo e os parâmetros ósseos de poedeiras. No experimento 1, utilizaram-se 240 aves com 40 semanas de idade distribuídas em esquema fatorial 5 × 2, composto de cinco níveis de fósforo disponível (0,094; 0,194; 0,294; 0,394 e 0,494%) e dois de fitase (0 e 300 unidades de fitase - UF). No experimento 2, utilizaram-se 288 aves com 44 semanas de idade, distribuídas também em esquema fatorial 3 × 4, composto de três níveis de fósforo disponível (0,094; 0,294 e 0,494%) e quatro de fitase (0; 300; 600 e 1.200 UF). No experimento 1, não houve interação fósforo disponível × fitase, mas o nível de fósforo disponível influenciou, de forma quadrática, a produção (PR) e a massa (MO) de ovos, os níveis plasmáticos de fósforo e a conversão por massa de ovos (CMO) e, de forma linear, o teor de cinzas na tíbia (CT) e a resistência óssea (RO). A adição de 300 UF elevou a disponibilidade do fósforo (de 4,034 para 4,784 mg/dL), o teor de CT (de 41,55 para 42,90%) e a resistência óssea (de 9,678 para 11,135 kgf/mm). No experimento 2, a produção aumentou de forma linear com os níveis de fósforo disponível da ração, que aumentaram linearmente com o aumento do nível de fitase. Os teores de cinzas na tíbia aumentaram até o nível de 567 UF. O aumento do fósforo disponível no nível de 600 UF melhorou de forma linear a massa de ovos, a conversão por massa de ovos e a conversão por dúzia de ovos. A suplementação da ração com menor teor de fósforo disponível (0,094%) com 300 a 1.200 UF melhorou a resistência óssea das aves. Poedeiras exigem em média 0,31 a 0,34% Pd. A adição de 300 UF ou o aumento do fósforo disponível em rações com 600 UF melhora a conversão por massa de ovos. A suplementação de rações deficientes em fósforo disponível com pelo menos 300 UF aumenta os níveis plasmáticos de fósforo, os teores de cinzas na tíbia e a resistência óssea de poedeiras comerciais.

Interação genótipo x ambiente e características pré-desmama em animais da raça Simental em duas estações de nascimento

O objetivo deste trabalho foi avaliar o efeito da interação genótipo x ambiente (GxA), nas características peso à desmama e ganho de peso do nascimento à desmama, em machos e fêmeas da raça Simental, nascidos nas estações chuvosa e seca. Foram avaliados 20 mil animais, aos 210 dias de idade. Realizou-se uma análise multicaracterística, que considerou como distinta a mesma característica nos diferentes grupos ambientais, e uma análise unicaracterística, que considerou cada característica como a mesma em todos os grupos ambientais. Ainteração GxA foi avaliada por meio da correlação genética (r g). As interações foram consideradas importantes quando os valores de r g ficaram abaixo de 0,80. As distribuições posteriores das estimativas de herdabilidades mostraram ausência de heterogeneidade de variâncias entre os sexos, entretanto houve interação GxA entre os grupos ambientais. Observaram-se valores de correlação genética de 0,54 a 0,78 e 0,55 a 0,75 para peso à desmama e ganho de peso do nascimento à desmama, respectivamente. As seleções, baseadas tanto na análise unicaracterística quanto na multicaracterística, não mostraram diferenças significativas quanto ao ganho genético dos animais. Há efeito das estações de nascimento nas características avaliadas, em todos os grupos ambientais, e a interação GxA é mais evidente em fêmeas do que em machos.

Interação genótipo-ambiente em cruzamentos de bovinos de corte

Dados de rebanhos bovinos comerciais foram analisados com o objetivo de estimar as interações dos efeitos genéticos com o ambiente que podem influenciar a avaliação de características de crescimento em rebanhos de animais puros e cruzados. O conjunto de dados analisado foi obtido a partir de animais das raças Hereford, Nelore e seus cruzamentos. As características em estudo foram os pesos à desmama e ao sobreano dos animais. As análises estatísticas foram realizadas pelo método dos quadrados mínimos e o modelo proposto incluiu os efeitos de região, grupo de contemporâneos dentro de região, mês de nascimento e sexo do bezerro, os efeitos lineares e quadráticos para a idade do bezerro e idade da vaca ao parto, ambas analisadas dentro de sexo, e os efeitos de grupo genético e da interação grupo genético × região. de modo geral, o desempenho de todos os grupos genéticos foi influenciado pelo efeito de região. Além disso, observou-se tendência de que o aumento da proporção de genes zebuínos promoveu diminuição na diferença de desempenho entre as regiões. Todos os genótipos foram beneficiados no ambiente menos restritivo, o que indica a existência de interação genótipo-ambiente e comprova a importância de que sistemas de cruzamento sejam realizados de forma a manter a adaptação das matrizes e de seus produtos.

Simulação computacional da interação fluido-estrutura em bombas de cavidades progressivas

The pumping through progressing cavities system has been more and more employed in the petroleum industry. This occurs because of its capacity of elevation of highly viscous oils or fluids with great concentration of sand or other solid particles. A Progressing Cavity Pump (PCP) consists, basically, of a rotor - a metallic device similar to an eccentric screw, and a stator - a steel tube internally covered by a double helix, which may be rigid or deformable/elastomeric. In general, it is submitted to a combination of well pressure with the pressure generated by the pumping process itself. In elastomeric PCPs, this combined effort compresses the stator and generates, or enlarges, the clearance existing between the rotor and the stator, thus reducing the closing effect between their cavities. Such opening of the sealing region produces what is known as fluid slip or slippage, reducing the efficiency of the PCP pumping system. Therefore, this research aims to develop a transient three-dimensional computational model that, based on single-lobe PCP kinematics, is able to simulate the fluid-structure interaction that occurs in the interior of metallic and elastomeric PCPs. The main goal is to evaluate the dynamic characteristics of PCP s efficiency based on detailed and instantaneous information of velocity, pressure and deformation fields in their interior. To reach these goals (development and use of the model), it was also necessary the development of a methodology for generation of dynamic, mobile and deformable, computational meshes representing fluid and structural regions of a PCP. This additional intermediary step has been characterized as the biggest challenge for the elaboration and running of the computational model due to the complex kinematic and critical geometry of this type of pump (different helix angles between rotor and stator as well as large length scale aspect ratios). The processes of dynamic generation of meshes and of simultaneous evaluation of the deformations suffered by the elastomer are fulfilled through subroutines written in Fortan 90 language that dynamically interact with the CFX/ANSYS fluid dynamic software. Since a structural elastic linear model is employed to evaluate elastomer deformations, it is not necessary to use any CAE package for structural analysis. However, an initial proposal for dynamic simulation using hyperelastic models through ANSYS software is also presented in this research. Validation of the results produced with the present methodology (mesh generation, flow simulation in metallic PCPs and simulation of fluid-structure interaction in elastomeric PCPs) is obtained through comparison with experimental results reported by the literature. It is expected that the development and application of such a computational model may provide better details of the dynamics of the flow within metallic and elastomeric PCPs, so that better control systems may be implemented in the artificial elevation area by PCP

A resistência de genótipos de abobrinha italiana Cucurbita pepo L. à broca das cucurbitáceas Diaphania nitidalis Cr. foi avaliada a campo. O genótipo Duda apresentou o maior número de frutos produzidos (33 frutos/parcela), enquanto Lita-186 foi o mais preferido, com a maior percentagem de frutos broqueados (3,6%). Os genótipos AG-202, Lita-186 e Duda, mais o inseticida deltametrina 25 CE foram avaliados. Duda comportou-se novamente como mais produtivo (35 frutos/parcela) e menos danificado (0,35%), confirmando os resultados obtidos no primeiro ensaio; já os genótipos AG-202 e Lita-186 revelaram-se os mais preferidos por D. nitidalis, com maiores índices de frutos danificados (2,7 e 6,3%, respectivamente).

Interação de doses de calcário e zinco nas características morfológicas e nos componentes de produção da mamoneira

O objetivo deste trabalho foi avaliar a influência de doses de calcário e zinco e, a interação destes sobre o desenvolvimento da cultura da mamona. A hipótese deste trabalho é que o aumento de doses de calcário diminui a disponibilidade de zinco no solo para a planta. O experimento foi desenvolvido em estufa para cultivo protegido, sem controle de temperatura, em vasos com 17 dm³ de Latossolo Vermelho distrófico, textura média. O delineamento experimental foi em blocos casualizados, com quatro repetições. Os tratamentos foram arranjados num esquema fatorial 3 x 5, sendo os fatores: três saturações por bases (40, 60 e 80%) e cinco doses adicionadas de Zn (0,5; 1,0; 2,0; 4,0 e 8,0 mg dm-3 de solo). Apenas uma planta por vaso foi conduzida até 174 dias após emergência (maturidade fisiológica do racemo primário), quando foi avaliada a produção. Maiores doses de calcário resultaram em maior número de grãos por planta e MS dos grãos por planta. Houve interação V% e Zn na altura da planta, massa seca da raiz, comprimento da parte masculina e total do racemo. No entanto, nenhum destes incrementos refletiu em diferença significativa na massa de 100 grãos da mamoneira.

Recuperação e purificação de proteínas do soro de queijo tipo coalho usando cromatografia de troca iônica e interação hidrofóbica em leito na forma expandida

Expanded Bed Adsorption plays an important role in the downstream processing mainly for reducing costs as well as steps besides could handling cells homogenates or fermentation broth. In this work Expanded Bed Adsorption was used to recover and purify whey proteins from coalho cheese manufacture using Streamline DEAE and Streamline SP both ionic resins as well as a hydrophobic resin Streamline Phenyl. A column of 2.6 cm inner diameter with 30 cm in height was coupled to a peristaltic pump. Hydrodynamics study was carried out with the three resins using Tris-HCl buffer in concentration of 30, 50 and 70 mM, with pH ranging from 7.0 to 8.0. In this case, assays of the expansion degree as well as Residence Time Distribution (RTD) were carried out. For the recovery and purification steps, a whey sample of 200 mL, was submitted to a column with 25mL of resin previously equilibrated with Tris/HCl (50 mM, pH 7.0) using a expanded bed. After washing, elution was carried out according the technique used. For ionic adsorption elution was carried out using 100 mL of Tris/HCl (50 mM, pH 7.0 in 1M NaCl). For Hydrophobyc interaction elution was carried out using Tris/HCl (50 mM, pH 7.0). Adsorption runs were carried out using the three resins as well as theirs combination. Results showed that for hydrodynamics studies a linear fit was observed for the three resins with a correlation coefficient (R2) about 0.9. In this case, Streamline Phenyl showed highest expansion degree reaching an expansion degree (H0/H) of 2.2. Bed porosity was of 0.7 when both resins Streamline DEAE and Streamline SP were used with StremLine Phenyl showing the highest bed porosity about 0.75. The number of theorical plates were 109, 41.5 and 17.8 and the axial dipersion coefficient (Daxial) were 0.5, 1.4 and 3.7 x 10-6 m2/s, for Streamline DEAE, Streamline SP and Streamline Phenyl, respectively. Whey proteins were adsorved fastly for the three resins with equilibrium reached in 10 minutes. Breakthrough curves showed that most of proteins stays in flowthrough as well as washing steps with 84, 77 and 96%, for Streamline DEAE, Streamline SP and Streamline Phenyl, respectively. It was observed protein peaks during elution for the three resins used. According to these peaks were identified 6 protein bands that could probably be albumin (69 KDa), lactoferrin (76 KDa), lactoperoxidase (89 KDa), β-lactoglobulin (18,3 KDa) e α-lactoalbumin (14 KDa), as well as the dimer of beta-lactoglobulin. The combined system compound for the elution of Streamline DEAE applied to the Streamline SP showed the best purification of whey proteins, mainly of the α-lactoalbumina
