The equilibrium charge-state distributions have been measured for sodium ions at the exit of a carbon foil for energies ranging from 0.43 to 1.66 Me V. A comparison of our results with available models is performed and an empirical formula for calculating the charge-state fractions of sodium ions is deduced. [less ▲]

This paper presents a procedure for computing approximate solution of bending Kirchhoff plate with an equilibrium finite element model. The accuracy of the equilibrium approach is evaluated through the concept of error estimator. Especially, a dual analysis by finite elements which leads to lower and upper bounds of the exact solution is presented in numerical examples. [less ▲]

A conforming displacement model for plate bending was presented earlier. It is of intyerest to have also an equilibrium moàdel available in order to generate both upper and lower bounds to plate deflections. The theory of the triangular equilibriium model, which is presented here, takes advantage of oblique coordinates. Il allows to cover transvers loading modes. Because the numerical investigations required adaptibility of the model to a stiffness computer-program, only the elaboration of the stiffness matrix was aimed at. The element can nevertheless be recognised as the Southwell analogue of the plane stress model with quadratic displacement field. As such it can be handled efficiently by a force program. Numerical results show the monotonic convergence of deflections from above for the equilibrium model and from below for the conforming model. The convergence rate, in terms of generalized coordinates, is compâred with that of other plate bending elements. [less ▲]

Multi-Modal freight models are traditionally built following the well known “four steps model” in which generation, distribution, modal-split and assignment are seen as separated modules. An alternative approach, now implemented in some software, is to represent the multi-modal network by means of a “mono-modal” one, in which each particular transport operation (loading or unloading operation, transhipments ...) is represented by a dedicated “virtual link”, that represents a specific operation in the transportation chain. This approach, promoted by several authors, often referenced to as “super networks” or “virtual networks”, is proven to give interesting results, but has the drawback to generate much larger networks than the pure geographic representation of the studied area. It has also some kind of “hidden trap”, linked to transport distances, that will be presented in this paper and that can only be solved using appropriate assignment techniques. This paper presents some results obtained on a large multi-modal network, using different equilibrium assignment algorithms, in order to test their ability to give an appropriate solution to the “distance trap”. It however concludes that the implementation of classical equilibrium assignment techniques leads to solutions that are barely different from the one obtained by a simple all-or-nothing assignment, opening the way to alternative multi-flow solutions.

Atypical myopathy (AM) is an acute rhabdomyolysis syndrome that occurs at irregular intervals in grazing equines. An increasing number of outbreaks have been reported in recent years, including some from countries where the disease has not previously been diagnosed. In this review, clinical and other details of outbreaks of AM are analysed to better define its epidemiological profile. Potential aetiologies are discussed, the short clinical course of AM is described and the main biochemical and pathological findings are considered. Recommendations for medical management are suggested, based on a review of clinical reports. Biochemical and histopathological findings have been integrated in order to characterise the physiopathology of AM. There is an ongoing requirement to record new cases of this syndrome, ideally through an epidemiological network. [less ▲]

Equine gammaherpesviruses (cEHV) have been widely studied over the past 45 years and many isolates have been characterised. Despite this, the diagnosis of cEHV infection remains difficult to establish as its clinical manifestations lack specificity, ranging from mild respiratory signs in a small number of animals to outbreaks in large groups of young horses. This review focuses on the epidemiology, pathogenesis, clinical manifestations and diagnosis of equine herpesvirus (EHV)-2 and -5 infections, as well as on the genetic variation of these viruses. Study of these variations has resulted in hypotheses relating to viral re-infection and re-activation. Interestingly, the viruses were found to contain genetic sequences identical to those of eukaryotic cells which are considered central to the development of viral latency through interfering with host immune and inflammatory responses. Future molecular biological studies will further elucidate the virulence mechanisms of these equine pathogens [less ▲]

The glaucomas are diseases that lead to the destruction of retinal ganglion cells and their axons via a number of mechanisms such as direct pressure damage, hypoxic and toxic injuries. The aim of this article is to present a review of this condition in horses in order to have a proactive attitude and to enable an early diagnosis to be made in order to determine the most adequate prophylactic (on predisposed individuals) and therapeutic treatment.

This study describes an equine joint friction test using a cartilage-on-cartilage arrangement and investigates the influence of age and load on the frictional response. Osteochondral plugs were extracted from equine shoulder joints (2-5 years, n=12; 10-14 years, n=15), and mounted in a pin-on-disc tribometer. The frictional response was then measured under constant conditions (2N; 20 degrees C; 5 mm/s), and with increasing load (2N, 5N, 10N). In all experiments, the friction coefficient of young cartilage was significantly (P<0.001) smaller than obtained from old cartilage, while the application of a greater load resulted in a significant (P<0.001) decrease in friction coefficient only in old cartilage. It was concluded that cartilage ageing was responsible for an increase in friction coefficient under these experimental conditions. Moreover, where young cartilage lubrication remained stable, cartilage ageing may have been responsible for lubrication regime change. The cartilage-on-cartilage model could be used to better understand lubrication regime disturbances in healthy and diseased equine joints, and to test the efficacy of various bio-lubricant treatments.

Diagnostic imaging of lung disease using radioactive tracers is a well-established procedure in human nuclear medicine. Conversely to other imaging techniques, gamma scintigraphy explores the functional and metabolic characteristics of an organ or a system rather than its morphology. Compared to other pulmonary function tests, scintigraphy provides regional evaluation instead of global measurement of lung function. For these reasons, this non invasive technique is a powerful tool for the study and diagnosis of respiratory disorders, as well as in the development of their treatment. In equine medicine the techniques to perform and analyse scintigraphic lung images have been described. Equine lung scintigraphy emerges as a diagnostic and research tool9. This paper describes the scintigraphic technique, the method for analysis of equine lung scintiscans, and reviews the potential application of equine lung scintigraphy. [less ▲]
