The authors present a novel nonlinear homogenization technique for laminated iron cores in three-dimensional (3-D) finite-element (FE) models of electromagnetic devices. The technique takes into account the eddy current effects in the stacked core without the need of modeling all laminations separately. A nonlinear constitutive magnetic law is considered. The system of nonlinear algebraic equations obtained after time discretization is solved by means of the Newton-Raphson scheme. By way of validation, the method is applied to a 3-D FE model of a laminated ring core with toroidal coil. [less ▲]

Wrinkles result from distinct structural changes occurring in specific parts of the dermis and subcutaneous tissue. There is a need for evidenced-based cosmetology identifying and quantifying the different aspects of wrinkling. Histology allows to detect specific changes associated with particular types of wrinkles. Four main types of wrinkles can thus be recognized, including the atrophic crinkling rhytids, the permanent elastotic creases, the dynamic expression lines, and the gravitational folds. Each type usually develops on specific skin regions exhibiting distinct microanatomical characteristics. Whereas skin microrelief, expression lines and skin folds appear clearly marked at the histological level, only little dermal changes are identified under other reducible or permanent wrinkles compared with the skin immediately adjacent to them. Distinguishing different types of wrinkles brings more precision to the clinical practice. This is of importance because the different types of wrinkles respond differently to cosmetic, dermatological and surgical treatments. [less ▲]

Several biological characteristics of bovine herpesvirus 4 (BoHV-4) make it a good candidate as a gene delivery vector for vaccination purposes. These characteristics include little or no pathogenicity, unlikely oncogenicity, the capability to accommodate large amounts of foreign genetic material, the ability to infect several cell types coming from different animal species, and the ability to maintain transgene expression in both undifferentiated and differentiated cells. Starting from BoHV-4 cloned as a bacterial artificial chromosome (BAC), we used MuA transposase-mediated in vitro transposition to generate recombinant BoHV-4 expressing the immunodominant glycoprotein D (gD) of BoHV-1, one of the most important pathogens of cattle. Although a cis-acting element from woodchuck hepatitis virus (the woodchuck hepatitis virus posttranscriptional regulatory element [WPRE]) in the 3' end of the gD expression cassette was required for maximal gD expression from plasmids in transient transfection assays, this element was not necessary for efficient expression of gD from recombinant BoHV-4 genomes. BoHV-4 recombinants containing gD expression cassettes with or without the WPRE expressed gD at similarly high levels. Several cell lines originating from different animal species expressed gD when infected with BoHV-4 recombinants. When rabbits were immunized with one of the recombinants, high levels of serum neutralizing antibodies against BoHV-1 were generated. This work is one of the first demonstrations of the use BoHV-4 as a vector for vaccine purposes and may provide the basis for BoHV-1 vaccination of cattle with recombinant BoHV-4. [less ▲]

This paper compares three methods to determine the earing profile that appears during the deep-drawing test of a circular steel sheet. Three steel grades will be studied. The first method is an experimental test made by a hydraulic press. The second one is a finite ele-ment method (FEM) deep-drawing simulation using a micro-macro texture based constitutive law. The last one directly determines the general aspect of the earing profile from the yield locus which is computed from the initial texture. The goal of this study is to validate the last approach. So, an earing profile prediction can quickly be obtained just from material’s tex-ture. [less ▲]

We study numerically and analytically the dynamics of passive energy transfer from a damped linear oscillator to an essentially nonlinear end attachment. This transfer is caused by either fundamental or subharmonic resonance capture, and in some cases is initiated by nonlinear beat phenomena. It is shown that, due to the essential nonlinearity, the end attachment is capable of passively absorbing broadband energy at both high and low frequencies, acting, in essence, as a passive broadband boundary controller. Complicated transitions in the damped dynamics can be interpreted based on the topological structure and bifurcations of the periodic solutions of the underlying undamped system. Moreover, complex resonance capture cascades are numerically encountered when we increase the number of degrees of freedom of the system. The ungrounded essentially nonlinear end attachment discussed in this work can find application in numerous practical settings, including vibration and shock isolation of structures, seismic isolation,. utter suppression, and packaging.

Using manual acoustic tracking our study quantified (1) the spatial distribution (2) the movement patterns and (3) the depth preference of adult whitefish, Coregonus lavaretus in it small artificial lake of eastern Belgium were the species was introduced in 1978 for recreational fishing. From June to October 2004, n=6 C. lavaretus (LF 285-519 mm) were tracked (pingers and depth sensor transmitters) from a small boat over periods ranging from 98 to 108 days in Robertville Lake (elevation: 490 m; area: 63 ha max. depth: 47 in). Whitefish were consistently mobile but showed quite variable lake use patterns. Two individuals traveled the entire length and breadth of the lake, whereas others remained in movement in the deep zone in the middle part of the lake or near the retaining darn wall. Whitefish occupied positions in the water column ranging front 2.6 to 27.0 m (mean 12.7 +/- 5.6 m) that varied depending on individuals. This first study on individual whitefish behaviour provides a better understanding of the behavioural ecology of the species in small artificial lake. [less ▲]

Cassava starchy storage roots are an excellent source of carbohydrates but lacking in protein. To enhance their nutritional quality, here we discuss several biotechnological strategies that might be used to increase protein levels as well as improved essential amino acid content in transgenic cassava. Application of such strategies in this major crop could, in the long term, help to fight against malnutrition in those regions which depend heavily on cassava consumption. © 2006 Elsevier Ltd.

The facies architecture, sedimentary dynamics and palaeogeographical evolution were reconstructed for a number of Middle to Late Frasnian buildups developed on a carbonate platform on the south side of the Dinant Synclinorium (Belgium, France). Nine facies were documented in the buildups, each characterized by a specific range of textures and assemblage of organisms. Sedimentological evidence suggests that facies (1) and (2) correspond to iron bacteria-sponge-dominated communities, developing in a quiet aphotic and hypoxic environment. (3) developed between the storm wave base and the fairweather wavebase, in a oligophotic environment. (5), with stromatolitic coatings and thrombolitic bushes developed close to the fairweather wave base. (6) and the fenestral limestone. (7) correspond to an environment with slightly restricted water circulation. (8) developed at subtidal depths in a quiet, lagoonal environment. The main differences between the Middle and Late Frasnian mounds concerns facies architecture and are a consequence of different palaeoceanographic setting. The large flattened Middle Frasnian Arche and Lion buildups show limited vertical differentiation, large-scale progradation features, extensive exportation of material towards off-reef environment and development of inner lagoonal facies. They grew offshore from a well-developed carbonate platform with a healthy carbonate factory. Middle Frasnian sea level fluctuations were relatively mild, and sedimentation was able to counterpart sea-level rise. At the opposite, during Late Frasnian, severe eustatic rises, together with rising oceanic hypoxic conditions were responsible for frequent collapses of the carbonate factory, drowning of the Middle Frasnian carbonate platform and development of buildups with relatively limited lateral extension, high vertical facies differentiation, low potential for material exportation and high content in microaerophilic iron bacteria.

BACKGROUND: Scarring is a complex process involving many cell types, cytokines and biological pathways including mechanobiology. Some subtle mechanical properties of skin can be assessed by measuring the speed of ultrasound shear wave propagation. The orientation of abnormal skin tension forces can be visualized, particularly in darker skin types, using dermoscopy showing distinct patterns of rete ridges' conformation. AIM: To assess some mechanobiological features of scars in darker skin types. PATIENTS AND METHODS: Large atrophic and hypertrophic surgical scars were examined on the trunk of 35 darker skin subjects. The surrounding skin was used as a comparator. Dermoscopic aspects were recorded. Resonance running time measurements (RRTM) were performed using a shear wave propagation device (Reviscometer). They were performed in four specific directions at given angles with regard to the long axis of the scar. The minimum, maximum and mean RRTM values were recorded at each site. RESULTS: Dermoscopy revealed patterns of melanin deposits in scars distinct from the normal honeycomb network seen in the surrounding skin. Hypertrophic scars showed a patchy pattern of large macular melanoderma dispersed in a lighter background. In these cases, low RRTM values were obtained with little variations according to the orientation of the measurements. By contrast, atrophic scars showed a streaky laddering melanotic pattern under dermoscopy. Higher RRTM values were often obtained, particularly in the transversal direction of the scars. Mechanical anisotropy was greater in the atrophic scars compared with the normal skin. DISCUSSION: Darker skin types represent a model for visualizing the main orientation of the epidermal rete ridges. A correlation was found between the pattern of melanized rete ridges of scars and the main orientation of the intrinsic forces in the skin. [less ▲]
