Deficiência androgênica na mulher

As evidências sugerem que a deficiência androgênica na mulher exibe como principal manifestação clínica a disfunção sexual, especialmente a queda da libido. Entretanto, outros fatores podem também estar implicados na gênese da disfunção sexual, como o relacionamento interpessoal, os estressores sociais, o sedentarismo e o próprio fator masculino. A prevalência da disfunção sexual feminina oscila entre 9 por cento e 43 por cento e recentemente muitos estudos têm mostrado que a reposição com androgênios não só melhora o desempenho sexual, mas também os distúrbios do humor e sintomas vasomotores. Por isso, o profissional de saúde deve sempre incluir no diagnóstico diferencial da disfunção sexual a Síndrome de Deficiência Androgênica, mesmo em mulheres com concentrações séricas normais de estrogênios. O presente artigo tem como objetivo revisar os aspectos práticos da Síndrome de Deficiência Androgênica, enfocando especialmente o diagnóstico e tratamento. Para tanto, nos valemos da análise de 105 artigos publicados em revistas indexadas no PUBMED nos últimos 51 anos (até maio de 2010), incluindo consensos e opiniões de especialistas. Como conclusão, a Síndrome de Deficiência Androgênica na mulher é negligenciada, existindo ainda muitas controvérsias quanto ao seu diagnóstico e terapêutica, especialmente no tocante à escolha do androgênio, a via de administração e o tempo de duração de uso

Escalas concorrentes para a mensuração da qualidade percebida: uma comparação entre a SERVQUAL e a RSQ

There is no doubt about the importance of service quality as a factor of businesses' success, but to measure this quality has proved to be a challenge when one considers different environmental contexts. Given this, the main goal of this paper was to test two measurement scales of perceived set-vice quality. The comparison between Service Quality scale (Servqual) and Retail Set-vice Quality (RSQ) was conducted by means of a survey with 351 participants, clients of a home center stores chain located in the city of Sao Paulo. The data were analyzed using both exploratory and confirmatory factor analysis. As a result, both scales demonstrated acceptable levels of reliability and validity However; the RSQ demonstrated a better performance in the nomological test since it was able to explain 43% of the loyalty towards the retailer; while the Servqual scale explained only 11%.

WOOD DENSITY VARIATION AND TREE RING DEMARCATION IN Gmelina arborea TREES USING X-RAY DENSITOMETRY

Due to its relationship with other properties, wood density is the main wood quality parameter. Modern, accurate methods - such as X-ray densitometry - are applied to determine the spatial distribution of density in wood sections and to evaluate wood quality. The objectives of this study were to determinate the influence of growing conditions on wood density variation and tree ring demarcation of gmelina trees from fast growing plantations in Costa Rica. The wood density was determined by X-ray densitometry method. Wood samples were cut from gmelina trees and were exposed to low X-rays. The radiographic films were developed and scanned using a 256 gray scale with 1000 dpi resolution and the wood density was determined by CRAD and CERD software. The results showed tree-ring boundaries were distinctly delimited in trees growing in site with rainfall lower than 25 10 mm/year. It was demonstrated that tree age, climatic conditions and management of plantation affects wood density and its variability. The specific effect of variables on wood density was quantified by for multiple regression method. It was determined that tree year explained 25.8% of the total variation of density and 19.9% were caused by climatic condition where the tree growing. Wood density was less affected by the intensity of forest management with 5.9% of total variation.

EFFECT OF FERTILIZATION ON CELL SIZE IN WOOD OF Eucalyptus grandis Hill Ex Maiden

The use of fertilization in forest stands results in yield gains, yet little attention has been directed to its potential effects on the quality of wood produced. Information is scarce about the effect of fertilization on anatomical structures of older Eucalyptus wood. This work aims to study the effect of fertilization on tissue cell size of wood from an Eucalyptus grandis stand at age 21 years, the management system of which is based on selective thinning and fertilizer application at the start of the thinning season. Factors to consider include: presence or absence of fertilizers, two log positions and five radial (pith to bark) positions. Results led to the conclusion that fertilization significantly influenced only vessel frequency. Vessel element length was influenced by tree height. Fiber length, fiber diameter, fiber wall thickness, vessel element length, vessel diameter and vessel frequency were influenced by the radial position of the sample in relation to the log. A positive correlation was observed between fiber length, fiber diameter, fiber wall thickness, vessel element length, vessel diameter, ray width and radial position, while a negative correlation was observed between ray frequency and radial position.

Produção de óleo essencial e balanço nutricional em Corymbia citriodora adubado com lodo de esgoto em diferentes espaçamentos

The Corymbia citriodora is one of the most cultivated species in Brazil for wood and essential oil production. The oil is obtained by the leaves distillation and the yield is around 2%. For the sustainability of leaves extraction is necessary a good nutritional replacement, because the leaves contain a large quantity of nutrients. The sewage sludge application in Corymbia plantations is a way to apply organic fertilizer and is also a good alternative for the final disposal of this residue. In this context, the objective of this study was to evaluate the sewage sludge use as fertilizer for the essential oil production in two different Spacing. The experiment was constituted by 4 blocks and the treatments were: i) Close spacing (1m x 1m) with sewage sludge + K and B; ii) Close spacing with mineral fertilization: iii) Regular spacing (3m x 1m) with sewage sludge + K and B; and iv) Regular spacing with mineral fertilization. When the C. citriodora plots were 12, 18, 24 and 30 months old, leaves and branches biomass and also essential oil production were quantified. It was observed that the system of close planting totalized a higher biomass, 3.8 times more than the conventional system, providing 3 times more essential oil production (363 l ha(-1) at the close spacing and 116 l ha(-1) at the regular Spacing during 30 months). No difference was found in the leaves or oil production with the use of sewage sludge or mineral fertilizer any of spacing studied The use of sewage sludge as fertilizer for Corymbia citriodora plantations may be an interesting alternative. because it supplies large quantities of nutrients and ensures a positive budget of nutrients in the ecosystem.

Efeito da aplicação de fertilização nitrogenada e lodo de esgoto nas características da madeira juvenil de árvores de Eucalyptus grandis

This work evaluated the wood anatomical and physical characteristics of 24 months-old Eucalyptus grandis trees, planted in 3x2m spacing and fertilized with nitrogen (6, 12, 18 month old) and sewage sludge (planting, 8 month old). For each treatment 10 eucalypts trees were cut according to the distribution of basal area. Wood samples were collected in different percentages of the total height to analyze the anatomical (vessels and fibers) and physical (wood density) characteristics. The results showed that the wood apparent density and wood basic density of the eucalypt trees in the nitrogen and sewage sludge were larger in comparison to the control. Radial profiles of wood apparent density, were similar in the three treatments, presenting the exected characteristics of juvenile wood of 24 months-old eucalypt trees. Fiber and vessel dimensions were not affected by fertilization.

INFLUENCE OF ALTITUDE, AGE AND DIAMETER ON YIELD AND ALPHA-BISABOLOL CONTENT OF CANDEIA TREES (Eremanthus erythropappus)

The heartwood of candeia tree is a source of essential oil rich in alpha-bisabolol, a substance widely used in the cosmetic and pharmaceutical industry. Bearing in mind the economic importance of alpha-bisabolol, this work aimed to evaluate the influence of tree age on the yield and content of alpha-bisabolol present in essential oil from candeia, considering two distinct reliefs and three diameter classes, in Aiuruoca region, south Minas Gerais state. The two distinct reliefs correspond respectively to one section of the stand growing at 1,000m of altitude (Area 1) and another section growing at 1,100m of altitude (Area 2). In each section, 15 trees were felled from among 3 different diameter classes. Discs were removed from the base of each tree to estimate their age by doing growth ring count. Soil samples were taken and Subjected to physical and chemical analysis. The logs were reduced into chips and random samples were taken for distillation to extract essential oil. The method used was steam distillation at a pressure of 2 kgf/cm(2)/2.5 h. The chemical analysis was performed in a gas chromatograph (GC) based on the alpha-bisabolol standard reference. The yield of essential oil from trees in Area I was higher than that from trees in Area 2, with the same pattern of influence for older trees. In Area 2, the alpha-bisabolol content was higher in younger trees. No differences were found between the relevant parameters in relation to diameter classes.

Interceptação da chuva por duas espécies arbóreas em áreas verdes urbanas

Rainfall interception by the two most usual species in forest urban spaces was analysed by measuring of interception (I) or interception losses, through fall (PI), stem flow (Et) and gross precipitation (PT). The chosen species were Caesalpinia pluviosa DC. (Fabaceae: Caesalpinoideae) or sibipiruna, and Tipuana tipu O. Kuntze (Fabaceae: Faboideae) or tipuana. The individuals analysed were more than 50 years old, with three separate individuals and three individuals in each studied group of species at the campus of ""Luiz de Queiroz"" College of Agriculture (University of Sao Paulo), Piracicaba. The experiments were carried out from January to February 2007. Water was collected using seven-litre pails, in the edges and in the centre of the canopies. A high correlation of Th with Pg was observed on the centre of the crow of tipuana and by the edges of sibipiruna. Stand! had low correlation with Pg for both species. The average of rain interception was greater in the edges of the crow of sibipiruna individuals, 60.6%, and in the centre of tipuana crow, 59.40%. Thus, both species intercepted up to 60% of the water rainfall, which indicates a great potential of both species for arborisation in urban environments.

THE RELEVANCE OF SUBSIDIARY INITIATIVES FOR BRAZILIAN MULTINATIONALS

The put-pose of this paper is to analyze relationship patterns between headquarters and subsidiaries of Brazilian Multinationals Enterprises (BrMNEs). The key construct for that investigation is Subsidiary Initiative, which comprises Subsidiary Entrepreneurial Orientation, Autonomy, Integration, Local Competitive Context and Business Network. A survey was carried out in a sample of 65 subsidiaries of 29 BrMNEs. The main outcome is that subsidiaries are highly integrated and receive Entrepreneurial Orientation from Headquarters (HQs), but Initiative is limited. Actually, the main determinants of subsidiary's initiatives are Local Context and Business Networking in the host country. This apparent paradox may be explained by what we call 'rebellious subsidiaries', which take initiatives based on their business environment and connections, regardless of their HQs' directions or delegation of autonomy.

Antecedentes do relacionamento e da performance em empresas da cadeia de suprimentos: estruturação e aplicação de modelos de equações estruturais

The relationship between companies is an important issue in the management of supply chains. Several aspects relating to the flow and exchange of information along the chain are considered as having a decisive influence on the success of this relationship. The main objective of this work was to structured and test models that link aspects of this nature with performance and the purchaser-supplier relationship in the supply chain. Aspects relevant to communication and the use do IT in relationships between companies were investigated. The importance of performance in this relationship was also investigated. The research were based on empirical data obtained by means of structural equation modeling. The results show that some aspects contribute in a significant way to the success of this relationship while others that, a priori, are considered important make no contribution.
