This paper will present a way to minimize cost in shipbuilding industry by using the results of a data mining analysis aiming to improve the cost knowledge of the straightening process. This statistical analysis was based on production data from a shipyard and has the scope to establish an assessment formula of the straightening workload. An intermediate step of the analysis was to estimate the welding distortions appearing in stiffened panels. Those generated formulae are useful to improve the research in the following domains: production simulation, cost assessment of ship hull, structure optimization, design for production, etc. [less ▲]

In Northern Europe, bluetongue caused by the bluetongue virus, serotype 8 (BTV-8), emerged in August 2006 and numerous ruminant herds were found to be affected in 2007. An epidemiological postal survey was sent to 502 sheep holders with the help of the sheep and goats inter-professional federation (called FICOW). A total of 18% of holders responded (mainly meat holders). These holders market their animals on short circuit (direct sales). Despite morbidity and mortality, animal sterility (still not quantified) and lower growth, costs of animal treatment were important (sick animals and/or animals living with sick animals): minimum = 2 €/animal treated; maximum = 135 € / animal treated; mean = 26 €/animal treated and median = 20 €/animal treated. Except for rams, the price of animals (for reproduction and meat) has not varied significantly while the survey was conducted. A second postal survey is programmed after the lambing period to assess reproductive and other economic losses that could not be quantified by the time this surveywas run. [less ▲]

A pilot study has been carried out in order to assess the productivity of various sites for oak (Quercus sessilis) growth in belgian Ardenne. Site quality is evaluated by the measurement of top height at a kay dominant girth of 160 cm. Such a site index seems to be well suited to unevenaged forest structures. Some other calcultations concern relationships between the index and various site factors as aspect, soils and species of plants naturally occuring on the studied areas. Estimations of stands volumes are also made with particular stand volume equations. [less ▲]

Stand volume equations have been calculated on the basis of data issued from more than 400 sampling plots measured in stands of oaks located in the Sourthern part of Belgium.

This paper is devoted to the non linear quasi-steady aerodynamic loading. A linear approximation is often used to compute the response of structures to buffeting forces. Some researchers have however shown that it is possible to account for the non linearity of this loading. This non linearity can come (i) from the squared velocity or (ii) from the shape of the aerodynamic coefficients (as functions of the wind angle of attack). In this paper, we show that this second origin can have significant implications on the design of the structure, particularly when the non linearity of the aerodynamic coefficient is important (obvious, isn’t it?) or when the transverse turbulence is important.

L’objectif de l’étude était d’évaluer les capacités de changement d’un adolescent présentant un comportement à risque : être fumeur. Septante adolescents (13 à 18 ans) ont été recrutés : le groupe expérimental comprend trente-sept jeunes fumeurs ; le groupe contrôle trente-trois jeunes non -fumeurs. Les fumeurs ont été vus trois fois alors que les sujets du groupe contrôle ont été vus 2 fois sur une période de trois mois. Les principaux questionnaires sont : un questionnaire sociodémographique, l’échelle d’estime de soi de Rosenberg, l’Inventaire Systémique de Qualité de Vie pour Adolescents, trois questions ouvertes qui portent sur le changement, les ressources et la confiance en soi. Les techniques d’intervention sont la balance décisionnelle de l’entretien motivationnel et l’implémentation d’un comportement. Les résultats montrent un effet des entretiens motivationnels chez les fumeurs sur la perception d’être prêt au changement (p = 0,002), sur une meilleure perception de leurs ressources (p<0,001) et sur une augmentation de leur confiance en leur capacité de changement (p = 0,02). L’estime de soi et le score d’écart de qualité de vie restent stables pendant les trois mois à l’exception du score de but des jeunes fumeurs. L’implication clinique de ces résultas sera discutée lors de la présentation orale. [less ▲]

OBJECTIVE: To study the effects of estradiol and progesterone on the proliferation of normal human breast epithelial cells in vivo. DESIGN: Double-blind randomized study. SETTING: Departments of gynecology and of cell biology at a university hospital. PATIENT(S): Forty postmenopausal women with untreated menopause and documented plasma FSH levels of >30 mIU/mL and estradiol levels of <20 pg/mL. INTERVENTION(S): Daily topical application to both breasts of a gel containing a placebo, estradiol, progesterone, or a combination of estradiol and progesterone during the 14 days preceding esthetic breast surgery or excision of a benign lesion. MAIN OUTCOME MEASURE(S): Plasma and breast tissue concentrations of estradiol and progesterone. Epithelial cell cycles were evaluated in normal breast tissue by counting mitoses and performing quantitative proliferating cell nuclear antigen immunolabeling analyses. RESULT(S): Increasing the estradiol concentration enhanced the number of cycling epithelial cells, whereas increasing the progesterone concentration significantly limited the number of cycling epithelial cells. CONCLUSION(S): Exposure to progesterone for 14 days reduced the estradiol-induced proliferation of normal breast epithelial cells in vivo. [less ▲]

Two experiments were performed to characterize the process of postnatal demasculinization in Japanese quail. In the first experiment, it was shown that estradiol (E2) can complete female demasculinization during the first 4 weeks of life. By contrast, E2 did not demasculinize sexual behavior and cloacal gland in neonatally castrated males. Neonatally gonadectomized females preferentially performed mount attempts when tested in their home cage by comparison to a test arena. In Experiment 2, E2 Silastic implants (40-mm) maintained full copulatory behavior in castrated males but not in females. This large dose of E2 did not demasculinize adult sexually active birds (males or females) even if treatment lasted for 1 month. It is concluded that E2 can demasculinize sexual behavior only in females and only if treatment is performed in very young birds. [less ▲]

OBJECTIVE: A new matrix 17 beta-estradiol transdermal patch incorporating lauric acid to improve estradiol skin absorption has been designed for hormone replacement therapy. Estradiol pharmacokinetics obtained with the prototype, its industrial counterpart, a matrix-type, System 50, and a reservoir-type, Estraderm TTS 50, transdermal patch have been compared. Each device delivers 50 micrograms estradiol daily. METHODS: Twenty postmenopausal women received each of the four formulations for 3 days in a Latin-square design and with a minimum 4-day wash-out period between treatments. Estradiol plasma concentrations were measured by radioimmunoassay at 6, 12, 24, 48 and 72 h after application. RESULTS: The prototype patch and its industrial counterpart showed no significant difference in estradiol delivery, with 72-h systemic exposure to estradiol similar to that of the reservoir patch but greater than that of the reference matrix formulation, with average baseline-corrected concentrations (SEM) of 35 (4), 32 (3), 32 (2) and 19 (1.8) pg/ml, respectively. In addition, they ensured more stable delivery, with coefficients of variation of plasma estradiol concentrations (12-72 h) of 29, 41, 63 and 84%, respectively. All matrix patches demonstrated the same patients to be poor estradiol absorbers, different from those encountered with the reservoir patch type, despite an improved estradiol bioavailability with the lauric acid-containing matrix patch. CONCLUSION: Matrix patches incorporating lauric acid led to estradiol plasma levels more stable than with the reference matrix and reservoir patches, and greater than those with the reference matrix patch.
