Designing Non-Pneumatic Anti-Shock Trousers

Hemorrhagic shock is a significant cause of death for trauma patients. Current treatment methods face a variety of shortcomings and limitations. The team conducted research and testing which informed the design and prototyping of a device to combat hemorrhagic shock by shunting blood from the lower extremities to the core of the body. The team decided to create a fully functional segment of the device to study proof of concept and create a baseline for the future of the design. Verification testing showed that the device does not obstruct the cutaneous view. Furthermore, the team found the device can be applied within the identified time window of less than five minutes. It was measured that the device can apply 30-50 mmHg which is in the desired range of pressure to meet the device objectives

STEAM Workshop Development

The United Kingdom has increasingly marginalized the design and technology curriculum, leading to a dramatic decrease in the number of engineers and designers entering the workforce. Our project aided the Design Museum of London in its efforts to motivate student engagement in design and technology through digital design workshops. We researched educational practices, interviewed education professionals, and surveyed students to evaluate the effectiveness of existing workshops. To motivate students to engage more with design and technology, we recommended lesson plan updates, created pre- and post-visit modules for each workshop, and developed a proposal for a new workshop focused on how designers use computer code to create user interactions

Density of Wild Prey Modulates Lynx Kill Rates on Free-Ranging Domestic Sheep

Understanding the factors shaping the dynamics of carnivore–livestock conflicts is vital to facilitate large carnivore conservation in multi-use landscapes. We investigated how the density of their main wild prey, roe deer Capreolus capreolus, modulates individual Eurasian lynx Lynx lynx kill rates on free-ranging domestic sheep Ovis aries across a range of sheep and roe deer densities. Lynx kill rates on free-ranging domestic sheep were collected in south-eastern Norway from 1995 to 2011 along a gradient of different livestock and wild prey densities using VHF and GPS telemetry. We used zero-inflated negative binomial (ZINB) models including lynx sex, sheep density and an index of roe deer density as explanatory variables to model observed kill rates on sheep, and ranked the models based on their AICc values. The model including the effects of lynx sex and sheep density in the zero-inflation model and the effect of lynx sex and roe deer density in the negative binomial part received most support. Irrespective of sheep density and sex, we found the lowest sheep kill rates in areas with high densities of roe deer. As roe deer density decreased, males killed sheep at higher rates, and this pattern held for both high and low sheep densities. Similarly, females killed sheep at higher rates in areas with high densities of sheep and low densities of roe deer. However, when sheep densities were low females rarely killed sheep irrespective of roe deer density. Our quantification of depredation rates can be the first step towards establishing fairer compensation systems based on more accurate and area specific estimation of losses. This study demonstrates how we can use ecological theory to predict where losses of sheep will be greatest, and can be used to identify areas where mitigation measures are most likely to be needed
