A characteristic of incremental sheet metal forming is that much higher deformations can be achieved than conventional forming limits. In this paper it is investigated to which extent the highly non-monotonic strain paths during such a process may be responsible for this high formability. A Marciniak-Kuczynski (MK) model is used to predict the onset of necking of a sheet subjected to the strain paths obtained by finite-element simulations. The predicted forming limits are considerably higher than for monotonic loading, but still lower than the experimental ones. This discrepancy is attributed to the strain gradient over the sheet thickness, which is not taken into account in the currently used MK model. [less ▲]

M. haemolytica serotype A1 (formerly known as Pasteurella) is the most important and commonly isolated bacterial pathogen from fatal cases of bovine fibrinous pleuroneumonia. M. haemolytica and its two principal toxins, the lipopolysaccharides (LPS) and the leukotoxin (LktA) induce the recruitment, the activation and the necrosis of neutrophils involved in the pathogenicity of bovine pneumonic mannheimiosis (BPM). The objective of this study was to determine whether systemic therapy with carprofène (Rimadyl®*), a non-steroidal anti-inflammatory drug, improves the disease development in an acute experimental model of BPM. The experimental pathology was induced by trans-tracheal inoculation of M. haemolytica and toxins at T0. One hour post-inoculation, six calves were treated intravenously with carprofen (1,4 mg/kg) while six placebo-treated calves received dose-matched volumes of sterile saline. The clinical and biochemical parameters were measured at one (T+1), three (T+3) and seven (T+7) hours after inoculation. Disease scores for carprofen treated calves were significantly lower than those for placebo-treated controls six hours (T+7) after treatment. These results were associated to a significantly oxygen saturation decrease at T+3 and a significantly blood lactate increase at T+7 in the control calves. Moreover, pulmonary lesions were significantly less extensive than those in the control group. Taken together, this finding suggest that pharmacological modulation by carprofen of pulmonary inflammation after appearance of acute BPM clinical signs leads to calves’ health enhancement and reduces the extent of gross pneumonic lesion.

The electromagnetic interaction between Io and the jovian magnetic field leads to an auroral UV footprint consisting of single or multiple UV spots in both jovian hemi- spheres. According to current theories, the perturbation induced by the motion of Io in the plasma torus propagates along the field lines in the form of Alfvén waves and finally causes electron precipitation in the jovian ionosphere. The occurrence and mul- tiplicity of the secondary spots appear to be related to the position of Io in the plasma torus and have been attributed to partial reflections of the Alfvén waves on the torus boundaries. Nevertheless, the discrepancies between the predicted inter-spot distances and the measurements were found difficult to explain. Additionally, some crucial con- figurations of Io in the torus had never been observed. Our recent HST/ACS observations of the footprint in so far unexplored Io-plasma torus configurations lead to the finding of a new feature in the footprint: a faint spot upstream of the main spot. The observations of this precursor emission, together with the inconsistencies related to the inter-spot distances, suggest a new interpretation of the footprint morphology. We propose that the precursor and the first secondary spot stem from the same mechanism and we interpret them as the counterparts of the main spot occurring in the opposite hemisphere. [less ▲]

Strained silicon on insulators (sSOI) wafers with a supercritical thickness of 58 nm were produced using thin strain relaxed SiGe buffer layers, wafer bonding, selective etch back and epitaxial overgrowth. Raman spectroscopy revealed an homogeneous strain of 0.63 plusmn 0.03 % in the strained Si layer. Long channel n-type SOI-MOSFETs showed very large electron mobilities up to 1200 cm2/Vs in the strained Si devices. These values are more than two times larger than those of reference SOI n-MOSFETs. Mobility simulations with state of the art scattering models are then used to interpret the experiments. [less ▲]

The hypothalamic-pituitary-thyroid axis is of particular importance for the adaptation of mammals to their environment. Hypothyroidism is the most common type of thyroid disorders in cattle. Thyrotropin (TSH) is used in several mammalian species for the diagnosis of primary hypothyroidism. Currently in cattle, thyroid hormone assays are used to diagnose such disease. The aim of the study was to compare different tools for diagnosing hypothyroidism in newborn calves. Twelve goitrous newborn calves from two beef herds were studied as well as 45 healthy newborn calves. Bovine TSH, thyroxine (T4), tri-iodothyronine (T3), reverse-T3 (rT3), plasmatic inorganic iodine (PII) and glutathione peroxidase in erythrocytes (GPXe) were assayed in these calves during the first day of life. T4/T3 and T4/TSH ratio were calculated. Furthermore, TSH, T4, PII and GPXe were also assayed in their dams at calving. Results were analysed using Wilcoxon rank sum test and Spearman's rank correlation coefficient. A significant higher value (P < 0.01) of TSH was seen for the group of goitrous calves compared to healthy calves. There was no difference between healthy and goitrous calves for GPXe (P > 0.1) and PII (P > 0.05). Significantly higher values were seen for healthy calves compared to goitrous calves concerning T4, T4/T3 ratio, T4/TSH ratio, rT3 (P < 0.0 1) and T3 (P < 0.05). Regarding the group of goitrous calves, those that had larger goitre at palpation and were hairless (n=8) died within the first day of life while the four other with moderate goitre and normal hair stayed alive. Goitrous-dead calves had higher TSH values than goitrous-alive ones (P < 0.01), lower T4, T3, T4/TSH (P < 0.0 1) and rT3 (P < 0.05) but similar T4/T3 ratio (P > 0.1). Furthermore, it appeared that T4 and rT3 values in goitrous-alive calves were not different compared to healthy calves (P > 0.1). Regarding TSH (rho=0.44), T4 (rho=-0.44), PII (rho=0.70) and GPXe (rho=0.87), there was a correlation between healthy calves and their dams, with significantly higher values being found in the calves (P < 0.01). There was no correlation between values of TSH and T4 in goitrous calves and their dams (P > 0.1). However, for these animals there was a strong relationship in the values of PH (rho=0.82) and GPXe (rho=0.94) (P < 0.01). TSH, PII and GPXe were significantly higher in goitrous calves compared to their dams (P < 0.01). Regarding T4, only goitrous-dead calves showed significantly lower values than their dams (P < 0.01). Dams with goitrous calves had higher TSH (P < 0.01) and PII (P < 0.05) compared to dams with healthy calves but similar T4 and GPXe (P > 0.1). This study revealed that TSH alone is a good marker for hypothyroidism in newborn calves. In the absence of TSH assay, the T4/T3 ratio may be used to diagnose hypothyroidism in newborn calves. In our study, although T4/T3 ratio was helpful in identifying goitrous calves, it did not allow to discriminate goitrous-dead from goitrous-alive calves, contrary to TSH. In our study, the presence of a goitre in newborn calves could not be explained by the iodine (PII) and thyroid (via T4) status of their dams. [less ▲]

Long-term outcomes ( mean 38 +/- 17 months) were evaluated in 27 dogs with sinonasal aspergillosis after successful medical treatment using intranasal infusions of 1% or 2% enilconazole ( 1%, n= 15; 2%, n= 12). Long-term outcomes with both treatment protocols were good, with half of the dogs being asymptomatic throughout the follow-up period. The remaining dogs showed mild clinical signs compatible with chronic rhinitis/sinusitis. These clinical signs were interpreted as chronic lymphoplasmacytic rhinitis/sinusitis and episodes of bacterial rather than fungal infection. Three dogs had confirmed reinfection or relapse 2 to 36 months after clinical resolution. [less ▲]

Southern Belgium’s permanent forest inventory (IPRFW) has been running since February 1994. Its main objective is to identify and control the state and evolution of Wallonia’s forests. Because of the growing awareness of the importance of biodiversity and the potential ability of a national forest inventory to assess and monitor it (Köhl, 1996; Tomppo, 1996), since 1997 the inventory has been compiling exhaustive listings (relevés) of the vegetation present in each woodland-based field plot. The inventory was designed to use this floristic information to determine the forest type of each sample unit, characterizing its vegetation diversity and monitoring its evolution across the repeated measures of the inventory, normally taken every 10 years. The inventory’s current methodology for vegetation description is based on the well-known phytosociological relevé method of Braun-Blanquet. This chapter presents only a few examples of data processing results. Furthermore, several problems related to field operations and data processing are also analysed in order to enhance the next inventory cycle scheduled for 2008. The proposed methodological adjustments are designed in such a way that the data and results obtained are useful not only from the point of view of biodiversity, but also for everyday forest management practice. This chapter summarizes the current status of the regional forest inventory in Wallonia with respect to vegetation diversity issues and highlights the need for further methodological progress.
