Assessing factors contributing to the changes in historical temperature extremes and investigating future changes in extreme events
Temperature extremes are among the most studied features in the climate research community using both the observed datasets and the simulated outputs from climate models. Such extremes often lead to irreversible societal, ecological, and economic consequences across the globe. Moreover, projected …

Hill reaction and frost hardening in cabbage
… seeing plants surviving and struggling against temperature extremes which to all appearances have killed and destroyed other plants next to them? What inherent or developed ability is this that allows some to survive even when ice crystals were deposited on the leaves during early morning …

Changes in frequency of extreme temperature and precipitation events in Alaska
Decadal mean temperatures show a warming over the past 60 years at individual stations in Alaska. This research examines corresponding changes in frequencies of extremes of temperature and precipitation based on daily data from 26 Alaskan surface weather observing stations from 1950 to 2008. …

A non-dimensional analysis of cardiovascular function and thermoregulation
… plays a vital role in protecting the body from temperature extremes due to its unique ability to store, transport, and dissipate heat. A comprehensive study of the thermoregulatory aspects of the system is severely limited by its complexity and the interdependency of its many component …

Quantifying the effects of an increasingly warmer climate with a view to improving the resilience of Great Britain's railway network: Is a new stressing regime the answer?
The existing temperature profile in Great Britain determines the stress free temperature of continuous welded rail on the railway network, this ensures that cold-related tension cracks and heat-related rail buckles are kept within tolerable levels. It is predicted that winters will become warmer …

Evaluation of phase change material thermal control architectures for a WaferSatellite using integrated design and optimization techniques
… WaferSat has little heat capacity. Therefore, temperatures on the spacecraft rapidly approach extremes in eclipse and sunlight. Moreover, the highly integrated nature of WaferSat couples the thermal design challenge to other subsystems. This thesis seeks to explore the potential application of …

Are local range expansions in southerly populations of Aloidendron dichotomum early indicators of a future range shift?
… its range is suggested to be limited by low temperature extremes at the cool range edge and no such range shift has yet been confirmed. However, eco-physiological knowledge necessary to predict and detect this range shift is lacking. This study aimed to determine whether physiological …
