Two High Speed Steels (HSS) have been studied both having chemical compositions closed one to another. Both HSS grades exhibited similar matrix/carbides microstructure in the industrial as-cast conditions, except for M7C3 eutectic carbides only observed in one grade and fine pearlite only found in the other grade. Equilibrium diagrams were obtained from Thermodynamical simulations to enhanced predicted phase transformations whereas Differential Thermal Analysis was performed on both alloys in order to determine their crystallization behaviour in non equilibrium conditions. Light microscopy and Electron microscopy associated with microprobe analyses were done to characterize the microstructure of both alloys. Thermal treatments with related bulk hardness assessments were carried out to enhance conditions for pearlite formation at the end of the casting route. In continuous cooling conditions obtained from DTA simulations, the matrix of both as-cast HSS grades is composed of eutectic carbides, martensite and retained austenite, these phases exhibiting similar chemical compositions. The introduction of an intermediate isothermal stage in the solid state within the DTA cooling sequence leads to the formation of a fine pearlite phase mainly located in the vicinity of M2C eutectic carbides on one HSS grade. The origin of this fine pearlite is discussed in this paper. [less ▲]

For a single crystal of YNi(2)B(2)C superconductor, the equilibrium magnetization M in the square basal Plane has been studied experimentally as a function of temperature and magnetic field. While the magnetization M(H) deviates from conventional London predictions, a recent extension of London theory (to include effects of nonlocal electrodynamics) describes the experiments accurately. The resulting superconductive parameters are well behaved. These results are compared with corresponding findings for the case with M perpendicular to the basal plane. [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.

BACKGROUND: Equine atypical myopathy (AM) is a toxic rhabdomyolysis associated with ingestion of hypoglycin A, derived typically in Europe, from Acer pseudoplatanus tree. Despite the wide distribution of this tree species in the UK, the number of cases reported annually varies, and there has been an apparent increase in prevalence in recent years. Although AM was first recognised in the UK, epidemiological studies have never been conducted focused solely on this country. OBJECTIVES: To describe the spatiotemporal distribution, presentation, treatment and outcome of AM cases reported in the UK. STUDY DESIGN: Retrospective case series. METHODS: British AM cases reported to the atypical myopathy alert website, between 2011 and 2015 were included (n = 224). Data were obtained via standardised epidemiological questionnaires from owners and veterinarians. Factors associated with survival were assessed using logistic regression. RESULTS: Most cases reported were from England (87.9%). Survival was 38.6% (n = 73/189). Clinical factors associated with reduced odds of survival included, hypothermia (odds ratio (OR) 0.18; CI 0.06-0.57; p = 0.01), bladder distension (OR 0.11; CI 0.02-0.59; p = 0.01), tachycardia (OR 0.97; CI 0.94-0.99; p = 0.04) and serum creatine kinase activity >100,000 IU/L (OR 0.17; CI 0.04-0.68; p = 0.01) in the univariable analysis as well as recumbency. The latter was the only sign retained in multivariable analysis (OR = 0.19; CI 0.06-0.62; p = 0.006). Administration of vitamins during the disease was associated with survival (OR 3.75; CI 1.21-11.57; p = 0.02). MAIN LIMITATIONS: Reporting cases to the atypical myopathy alert group is voluntary; therefore, under-reporting will result in underestimation of AM cases; furthermore, direct owner-reporting could have introduced misdiagnosis bias. CONCLUSION: Some areas of the UK reported AM cases more commonly. Clinical signs such as recumbency, rectal temperature, distended bladder and serum CK activity might be useful prognostic indicators though should be considered in the context of the clinical picture. Treatment with vitamins increases survival. This article is protected by copyright. All rights reserved. [less ▲]

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 ▲]
