This document presents the development of a low-cost, right limb transhumeral prosthesis prototype, which incorporates basic movements to recover the performance of some activities of daily living for people who have suffered an amputation of the limb above the elbow. Firstly, the anthropometry of the patient’s limb is defined, which will set the prosthesis’s dimensioning. Afterward, a mechanism is established that meets the required degrees of freedom, and finally, the prosthesis prototype is designed considering materials, dimensions, and geometry for each part. It is mainly used 3D printing by deposition with ABS material, and conventional manufacturing processes with chip removal. The elements were designed, taking into account the anthropometric measurements of a 45-year-old transhumeral amputation patient with a height of 1.61 m, a 3D scan of the healthy arm, and the stump was performed with the Eva Artec scanner. The results consist of a prototype prosthesis with 4 degrees of freedom: flexion-extension of the elbow with a range of movement of 120°, prone supination with a range of movement of 180°, flexion-extension of the wrist with a range of movement of 60° and in the ulnar-radial deviation with a range of movement of 70°, with a total weight of 1.65 kg. The transhumeral prosthesis adapts to the prototype of the “MAKI 3.0” hand prosthesis, which has only one degree of freedom and a weighs 326 g.

Galápagos is one of the most pristine archipelagos in the world and its conservation relies upon research and sensible management. In recent decades both the interest in, and the needs of, the islands have increased, yet the funds and capacity for necessary research have remained limited. It has become, therefore, increasingly important to identify areas of priority research to assist decision-making in Galápagos conservation. This study identified 50 questions considered priorities for future research and management. The exercise involved the collaboration of policy makers, practitioners and researchers from more than 30 different organisations. Initially, 360 people were consulted to generate 781 questions. An established process of preworkshop voting and three rounds to reduce and reword the questions, followed by a two-day workshop, was used to produce the final 50 questions. The most common issues raised by this list of questions were human population growth, climate change and the impact of invasive alien species. These results have already been used by a range of organisations and politicians and are expected to provide the basis for future research on the islands so that its sustainability may be enhanced.
