Assistência de enfermagem e o risco para úlceras de pressão medido pela Escala de Braden em unidade de terapia intensiva

The problem facing the incidence of pressure ulcers (UP) in the hospital environment especially in the intensive care unit (ICU), although it is an old and frequent event in our professional practice, it is not notified in the researches as much as it should be. We observed a tendency to invest in therapeutical and in studies about the production of sophisticated new bandages. Few, however, are the investments in research on preventive measures in order to prevent or at least slow down the development of lesions. In this sense, the study aimed to analyze the correlation between nursing care and the risk of developing UP measured by the Braden scale in ICU patients. This is a descriptive study of longitudinal quantitative approach. The project obtained a favourable opinion from the Ethics Committee of HUOL (no 486/10). Data collection was carried out in the Hospital of Unimed in Natal during six months in 2011. The sample was of 32 patients hospitalized in ICU for over four days. The results were processed in SPSS 15.0 for descriptive statistics and inferential statistics. We identified that, only 9.4% of our sample developed UP, being predominantly male, elderly people aged above 60 years, Caucasian, with diagnostic hypothesis at the time of hospitalization of sepsis, were clinical patients, who presented hemodynamic instability, using orotracheal tube (TOT), enteral probe (SNE), vesical probe delay (SVD) and had values of albumin and hemoglobin levels below normal. In addition, these patients had a longer hospital stay, longer usage of TOT, SNE, SVD, increased use of sedation and drain than those who did not develop UP and were all at risk for developing these injuries second Braden scores. 66.7% of the lesions developed were located in the sacral region, limiting the degree I and all patients that developed were considered serious, 100.0% of them have evolved since the death. Small were the differences between the averages of Braden scores between patients with and without UP, 11,9+2,4 against 12,4+2,6 with p = 0.627. The clinical aspects of the patients in the study were instrumental in the development of UP, once, these findings were statistically significant through the Mann-Whitney test, and appropriateness of nursing conduct was decisive for the prevention of pressure ulcers in critical patients, since many were those classified as at risk (28) and few who have developed lesions (03)

Manganês na nutrição e na produção de massa seca do capim-mombaça

There are few studies that relate the micronutrient manganese nutritional status and production of fodder. The objective was to evaluate the application of manganese in the nutrition and growth of Mombaca grass. The completely randomized design was used with five manganese levels (0, 15, 30, 60, 120 mg dm(-3)) and four replicates. Each experimental unit consisted of a pot filled with 3.5 dm(-3) of soil from Oxisol (Mn = 0.6 mg dm(-3)), containing four plants. Two harvests were set, the first 44 days after sowing and the second 38 days after the first cut. The concentration of manganese in the soils, the manganese content of leaves, number of tillers, plant height, shoot dry mass in each slice and the root system of Mombaca grass were evaluated. The applied rates of manganese resulted in increased accumulation of Mn in the plant, and there was an increase in dry mass of Mombaca grass, with maximum production, obtained from derivation, of 5.9 and 6.3 g plant(-1) for levels of 121 and 71 mg dm(-3) of Mn in the first and second cut respectively. The Mombaca grass has showed high manganese's tolerance, the critical level of toxicity was 841 mg kg(-1) in the second cut.

Modos de aplicação de zinco na nutrição e na produção de matéria seca do milho BRS 1001

The culture of the maize is responsive the fertilization with zinc, however, its efficiency can be affected by the method of aplication. Thus, this work had as objective to evaluate the effect of the methods of zinc application in the nutritional state and the initial growth of the culture of the maize. The experiment was in a completely randomized design, with five treatments in four repetitions. The experimental unit was composed for a pot (7 L) filled with a distrofic Red Latosol, clayey texture, with four plants of maize. The treatments had been constituted by four ways of zinc application: in the soil incorporated (3 mg Zn dm(-3)), and located (1 mg Zn dm(-3)); foliar (solution of 23 mg Zn L(-1)); e in seed (40 g Zn kg(-1) of seed) and beyond the witness (control). The treatments had been applied during two cultivation of 42 days, except the Zn incorporated in the soil. In the end of each culture, the cut of the plants for the evaluation of the growth variable (leaf height, number, the diameter of stems and dry matter) and the determination of the zinc text was carried through in the soil and the aerial part. The zinc application promoted increment in the height and the production of matter of the maize. The zinc application soil (incorporated and located), foliar and seed had been similar in the initial development of the culture, however, the foliar way promoted greater absorption of the nutrient for the plant.

Modos de aplicação de zinco na nutricão e na produção de massa seca de plantas de trigo

Zinc application methods can affect the nutrition and the initial development of the wheat. Thus, the aim of this work was to analyze the different ways of Zn application in the soil, on nutrition and on dry matter production. A completely randomized experimental design with four replications was used. The experiment was composed by the following Zn application treatments: control (no zinc application); soil incorporation, furrow located, seeds treatment and leaf pulverization. The experimental unit was composed of a pot filled with 7 L of soil. Morphological traits for each plant were determined on 52 days after emergence by the evaluations of plant height, internodes number, tillers number and aerial part dry matter. Still, the soil and plant chemical analysis was accomplished. The furrow located method provided larger concentrations of the micronutrient available. The zinc application methods did not influence the initial growth of the wheat plants. The zinc concentration in leaves was influenced by the different application methods, being the leaf pulverization the one that was caused the largest zinc accumulation on aerial part dry matter.

A pegada de carbono como um dos indicadores de sustentabilidade para medição da responsabilidade socioambiental empresarial: um estudo de caso na unidade sede da Petrobras em Natal-RN

As a contemporary tendency, it is been evidenced that the environmental changes theme, already admitted as a concernment to international economical and political reality, is also gaining repercussion on industrial and business sector. Firms are implementing actions on trial to minimize their own greenhouse gases (GHG) emissions impacts. However, the great majority of those actions of Corporative Social-Environmental Responsibility (CSR) are referred only to direct emissions of the main production systems. Direct emissions are those derived of an isolate process, without considering the upstream and downstream processes emissions, which respond for the majority of emissions originated because of respective firm‟s production system existence. Because the greenhouse effect occurs globally and the GHG emissions contribute to the environmental changes independently of their origin, it must be taken into account the whole productive life cycle of products and systems, since the energy invested on resources extraction and necessary materials to the final disposal. To do so, it must be investigated all relevant steps of a product/production system life cycle, tracking all activities which emit greenhouse gases, directly or indirectly. This amount of emissions consists in the firm‟s Carbon Footprint. This research purpose is to defend the Carbon Footprint relevance and its adoption viability to be used as an Environmental Indicator on measurement/assessment of CSR. It has been realized a study case on Petrobras‟s seat unity at Natal-Brazil, assessing part of its Carbon Footprint. It has been used the software GEMIS 4.6 to do the emissions quantifying. The items measured were the direct emissions of the own unity vehicles and indirect emissions of offset paper (A4), energy and disposable plastic cups consumed. To 2009, these emissions were 3.811,94 tCO2eq. We may conclude that Carbon Footprint quantification is indispensable to the knowledge of real emissions caused by a productive process existence, must serving as basis to CSR decisions about the environmental changes reversion challenge

Custo de produção do maracujá-amarelo (Passiflora edulis)

Objetivou-se analisar economicamente a cultura do maracujá-amarelo (Passiflora edulis) na região de Marília-SP, safra de 2010/2011. Foram utilizadas estruturas do custo operacional efetivo e custo operacional total referente à fase de implantação e condução da lavoura por unidade de área e cinco indicadores de rentabilidade. Identificou-se um custo total de produção de R$ 37.751,67 por hectare ou R$ 1,89 por quilo da fruta. Os itens do custo operacional efetivo que mais oneraram o sistema de produção corresponderam às operações de máquinas (31,1%) e mão de obra (23,5%). Os indicadores de rentabilidade mostraram-se desfavoráveis para o sistema produtivo analisado, em decorrência, principalmente, do alto preço dos insumos e práticas para controle de doenças. Há necessidade de adequações técnicas relacionadas com o manejo fitossanitário da cultura para a redução do custo total de produção de modo a tornar a atividade rentável.

Viabilidade técnica de uma rota não convencional para a produção de leite de cabra em pó em cooperativas do Rio Grande do Norte

Nowadays, Brazil has both the greatest goat herd and the greatest goat milk production of South America. The state of Rio Grande do Norte, located in northeast of Brazil, has an average year production of three thousand cubic meters of goat milk in natura. Part of this milk production is homemade and it comes from small farms, which unite in rural cooperatives created to encourage the production and implementation of industrial processes for preservation and processing of milk. Results presented by literature and obtained from preliminary essays in this thesis show that non conventional dryer of spouted bed with inert particles is able to produce powder milk from in natura milk (cattle or goat), with the same quality of spray dryer, however, operating at low cost. The method of drying in spouted bed consists of injecting milk emulsion on the bed of inert particles gushed by hot air. This emulsion covers the particles with a thin film, which dries and is reduced to powder during the circulation of inerts inside the bed. The powder is dragged by exhaustion air and separated in the cyclone. The friction among particles resulted from the particles circulation, encourages high taxes of shear in the thin film of emulsion, breaking the cohesive forces and making this process possible. Studying the drying process and the powder goat milk production in one unit of spouted bed with inert particles, seeing the development of a low cost technological route for powder milk production is the aim of this thesis. The powder milk produced by this route must attend the local demand of food industries which need an intermediate product to be used as a food ingredient (ice-cream, milk candy). In order to reach this aim, this thesis approaches the aspects related to physical, thermodynamics and physic-chemicals characteristics of goat milk, whose complete data are still inexistent in the literature. The properties of materials are of great importance to the project of any process which involves the operations of transportation of movement, heat and mass quantity, such as the dryers which operate in fluid dynamically active regime, like the spouted bed. It was obtained new data related to the goat milk properties in function of concentration of solids and temperature. It is also important to mention the study developed about the kinetic of solids retention in the bed of inert particles during the drying of goat milk. It was found more adequate processes conditions to the proposed technological route to be implemented in small and micro-industries, with simplifications in the system of milk injection as well as in the form of operation of the dryer. Important data were obtained for a posterior stage of this research which involves the v modeling, simulation, control and optimization of the process. The results obtained in this thesis, in relation to process performance as well as to the quality of produced powder milk validate the proposal of using the spouted bed dryer in the production of powder goat milk
