- This study provides a computational model developed to demonstrate the possibility of monitoring hoof structure and health in equestrian sport. This is achieved by employing finite element simulation of threedimensional heat flow from a surface heat source into a hoof structure while simultaneously sensing the surface temperature. The time evolution of the recorded surface temperature, transient curve, is used to investigate hoof structure and predict its intactness by comparing these curves for three different models. We have observed differences between the transient curves obtained from a normal hoof structure, a hoof structure containing a foreign material and hoof capsule subjected to wall separation. An experimental method for probing hoof profile was briefly discussed. It uses temperature sensor/heat source. The method can determine the thermal conductivity of the hoof along the hoof structure from the recorded transient curve. Thus, it displays the hoof structure by utilizing the thermal conductivity variation between the hoof parts.

- IntroductionIn Sweden, the incidence of cutaneous malignant melanoma rises yearly with 5.5% for men and 5.2% for women and has now reached world standard rates of 17.6 for men and 18.8 for women per 100,000 population. Over the past decades, the incidence of melanoma has been higher in Western Sweden than the national average. Previous international studies have shown that melanoma patients have an elevated risk of developing a new separate primary melanoma. This study aimed at describing multiple primary melanomas (MPMs) in Western Sweden with focus on the number of tumours detected, tumour characteristics and the time to diagnosis of a subsequent melanoma.MethodsData was extracted retrospectively from the Swedish Melanoma Registry and provided information on all invasive and in situ melanoma cases in Western Sweden (1.6 million inhabitants) from 1990 to 2013. Results Within the studied period, 12,152 patients developed 13,291 melanomas. 11,254 of the patients developed only a single primary melanoma. In total, 898 patients (7.4% of all melanoma patients) developed 2,037 MPMs. Preliminary results show that the median Breslow thickness for all invasive melanomas was below 1 mm. The median Breslow thickness for the MPMs was slightly thinner for the second and third invasive melanoma as compared to the first invasive melanoma. Further, there was a higher percentage of in situ tumours among the subsequent melanomas. The median time to diagnosis of a subsequent melanoma was approximately 3 years. DiscussionSubsequent primary melanomas in Western Sweden are most commonly diagnosed with a somewhat thinner Breslow thickness than the first primary melanoma. The comparatively high percentage of melanoma survivors developing MPMs and the short median time to diagnosis of a subsequent melanoma stresses the importance of follow-up for melanoma patients, particularly during the first years.

Molecular dynamics study of the surface melting of iron clusters

- Molecular dynamics simulations have been used to study the surface melting of iron clusters. It is found that, even when the temperature is several hundreds of Kelvin below the cluster melting point, the crystalline center of the cluster is surrounded by surface atoms that exhibit large amplitude diffusion from their original positions. This results in surface melting of the cluster.
