No full textFamilial congenital pseudarthrosis of the ulna
No full textA mother and daughter, both presented with congenital pseudarthrosis of the ulna due to neuro-fibromatosis. The daughter is one of identical twins, the second twin not having a pseudarthrosis. The mother's uncle also had pseudarthrosis of the tibia. This suggests a complex variable genetic inheritance pattern for pseudarthrosis in neurofibromatosis. Despite having had no treatment, the mother had minimal symptoms, minimal deformity, and no radial head dislocation.<br/

On X-normed spaces and operator theory on c_0 over a field with a Krull valuation of arbitrary rank
No full textBetween 2013 and 2015 Aguayo et al. developed an operator theory on the space c0 of null sequences in the complex Levi-Civita field by defining an inner product on c0 that induces the supremum norm on c0 and then studying compact and self-adjoint operators on c0, thus presenting a striking analogy between c0 over the complex Levi-Civita field and the Hilbert space l2 over the complex numbers field. In this thesis, the author tries to obtain these results in the most general case possible by considering a base field with a Krull valuation taking values in an arbitrary commutative group. This leads to the concept of X-normed spaces, which are spaces with norms taking values in a totally ordered set X not necessarily embedded in the field of real numbers.February 201
A three-dimensional finite element model of maximal grip loading in the human wrist
No full textThe aim of this work was to create an anatomically accurate three-dimensional finite element model of the wrist, applying subject-specific loading and quantifying the internal load transfer through the joint during maximal grip. For three subjects, representing the anatomical variation at the wrist, loading on each digit was measured during a maximal grip strength test with simultaneous motion capture. The internal metacarpophalangeal joint load was calculated using a biomechanical model. High-resolution magnetic resonance scans were acquired to quantify bone geometry. Finite element analysis was performed, with ligaments and tendons added, to calculate the internal load distribution. It was found that for the maximal grip the thumb carried the highest load, an average of 72.2 ¡ 20.1 N in the neutral position. Results from the finite element model suggested that the highest regions of stress were located at the radial aspect of the carpus. Most of the load was transmitted through the radius, 87.5 per cent, as opposed to 12.5 per cent through the ulna with the wrist in a neutral position. A fully three-dimensional finite element analysis of the wrist using subject-specific anatomy and loading conditions was performed. The study emphasizes the importance of modelling a large ensemble of subjects in order to capture the spectrum of the load transfer through the wrist due to anatomical variation
Learning of algorithms: a theoretical model with focus on cognitive development
No full textTaking a broad perspective on algorithm in mathematics, the author presents a theoretical model about the learning and teaching of algorithm with focus on students’ cognitive development. The model consists of three cognitive levels: 1. Knowledge and Skills, 2. Understanding and Comprehension, and 3. Evaluation and Construction. The model suggests that teaching and learning of algorithm does not simply mean routine learning, memorization, or lead to a low level of cognition. The paper also discusses different teaching strategies and activities that can be used to support students’ cognitive development at different cognitive levels
