This paper presents and describes an intermediate approach which takes its place between the two classical methods of shape and topology optimization. It is based on using the recent Level Set description of the geometry and the novel eXtended Finite Element Method (X-FEM). The method benefits from the fixed mesh work using X-FEM and from the curves smoothness of the Level Set description. Design variables are shape parameters of basic geometric features. The number of design variables of this formulation remains small whereas various global and local constraints can be considered. A key problem which is investigated here is the sensitivity analysis and the way it can be carried out precisely and efficiently. Numerical applications revisit some classical 2D (academic) benchmarks from shape optimization and illustrate the great interest of using X-FEM and Level Set description together. The paper presents the results of stress constrained problems using the proposed X-FEM and Level Set based formulation. A central issue is the sensitivity analysis (related to the compliance and/or the stresses) and the way it can be carried out efficiently. A special attention is also paid to stress constrained problems which are often neglected in other Level Set Methods works. [less ▲]

Chicory root pectin was isolated by acid extraction followed by alcohol precipitation. Because the extraction conditions have important effects on the features of pectins, an experimental design was used to study the influence of 17 different extraction parameters on yield and composition of pectin: pH, temperature, time of extraction, solid/liquid ratio, and different pretreatments of the pulps before extraction. Twenty extractions were conducted and examined for their significance on yield and sugar content using the Plackett-Burman factorial design. The acid extraction of chicory roots resulted in an average yield of 11% containing 86% of sugars. It was found that extraction temperature, time, protease pretreatment, water purity, and water washing of pulps significantly affected yield and pectin composition with an increase of yield and purity of pectin in harsher extraction conditions.

Vocal fold hypomobility after thyroidectomy is a frequent complication of thyroidectomy. Laryngeal nerve paresis or paralysis may present with various symptoms like dysphagia, aspiration, voice alteration or dyspnea. Are described: the normal anatomophysiology of the larynx, the symptoms of nerve trauma following thyroidectomy, techniques of thoroughfull laryngeal and voice examination, some clinical entities( unilateral recurrent nerve paralysis, bilateral recurrent nerve paralysis, superior laryngeal nerve paralysis),natural evolution of paralysis, prognosis and management of laryngeal paralysis) [less ▲]

Handling model complexity and reliability is a key area of research today. While complex models containing sufficient detail have become possible due to increased computing power, they often lead to too much uncertainty. On the other hand, very simple models often crudely oversimplify the real ecosystem and can not be used for management purposes. Starting from a complex and validated 1D pelagic ecosystem model of the Ligurian Sea (NW Mediterranean Sea), we derived simplified aggregated models in which either the unbalanced algal growth, the functional group diversity or the explicit description of the microbial loop was sacrificed. To overcome the problem of data availability with adequate spatial and temporal resolution, the outputs of the complex model are used as the baseline of perfect knowledge to calibrate the simplified models. Objective criteria of model performance were used to compare the simplified models' results to the complex model output and to the available data at the DYFAMED station in the central Ligurian Sea. We show that even the simplest (NPZD) model is able to represent the global ecosystem features described by the complex model (e.g. primary and secondary productions, particulate organic matter export flux, etc.). However, a certain degree of sophistication in the formulation of some biogeochemical processes is required to produce realistic behaviors (e.g. the phytoplankton competition, the potential carbon or nitrogen limitation of the zooplankton ingestion, the model trophic closure, etc.). In general, a 9 state-variable model that has the functional group diversity removed, but which retains the bacterial loop and the unbalanced algal growth, performs best. (C) 2006 Elsevier Ltd.

For the past few years the inhabitants of a hamlet on the outskirts of the village of Ingleton in Yorkshire, England, have been witnessing a strange exercise every morning. A woman, said to have been one of the most renowned primatologists in the English-speaking world, spends her day in a field in front of her house, observing animals that she has put there. As she did during her many years of field work in Africa studying apes, primatologist Thelma Rowell patiently notes all the movements, anecdotes and tiny events making up the daily social life of the animals to which she is currently devoting her time. Admittedly, these animals are different to the ones she was used to spending time with: the relations are not characterized by the same intensity, the behaviors are peculiar to the species, the communication does not always pass by the same channels, and the events seem to take place at another pace. But as far as their social expertise is concerned, these animals are certainly on a par with apes. [less ▲]

"Heaves" is a recurrent allergic inflammatory disease initiated by inhalation of organic dust from hay and litter. Reduction in exposure to dust is the basis of prevention and treatment of attacks in horses. Substitution of hay by wilted grass silage is recommended but is often not given because of the required high work load and possible risk of botulism. An alternative is the use of fibrous food without forage. Nine "heave" horses were placed in two groups at random. One group received concentrate enriched with short-strand lucerne for six weeks and the other group the reference feed consisting of silage based concentrate. After a period of recovery, the protocol was repeated and the groups reversed. Respiratory and circulatory functions, degree of fatness, feeding time and consumption of water were evaluated. No significant difference in respiratory and circulatory parameters was observed. The feeding time was significantly higher for concentrate enriched with lucerne fibers. A concentrate rich in fibers may limit attacks as does silage, which has risks associated with consumption [less ▲]
