At this point in the unit, students have learned about Pascal's law, Archimedes' principle, Bernoulli's principle, and why above-ground storage tanks are of major concern in the Houston Ship Channel and other coastal areas. In this culminating activity, student groups act as engineering design teams to derive equations to determine the stability of specific above-ground storage tank scenarios with given tank specifications and liquid contents. With their floatation analyses completed and the stability determined, students analyze the tank stability in specific storm conditions. Then, teams are challenged to come up with improved storage tank designs to make them less vulnerable to uplift, displacement and buckling in storm conditions. Teams present their analyses and design ideas in short class presentations.
Students are provided with an introduction to above-ground storage tanks, specifically how and why they are used in the Houston Ship Channel. The introduction includes many photographic examples of petrochemical tank failures during major storms and describes the consequences in environmental pollution and costs to disrupted businesses and lives, as well as the lack of safety codes and provisions to better secure the tanks in coastal regions regularly visited by hurricanes. Students learn how the concepts of Archimedes' principle and Pascal's law act out in the form of the uplifting and buckling seen in the damaged and destroyed tanks, which sets the stage for the real-world engineering challenge presented in the associated activity to design new and/or improved storage tanks that can survive storm conditions.

Analytic epidemiological studies aim to investigate and identify factors associated with the presence of disease within populations, through the investigation of factors which may vary between individual members of these populations. Details on study designs appropriate for these investigations are given elsewhere. Conceptually, this involves investigating the disease experience amongst different 'groups' of animals within an overall population, distinguished according to the factor(s) of interest. These factors can be classified as one of the components of the 'epidemiological triad' of Host, Agent and Environment, many of which are closely interrelated with each other.

We will consider theories pertaining to civil society development, social movement mobilization, and relations between state and non-state actors. During the course of the semester, particular attention will be given to the legitimacy and accountability of nongovernmental organizations (NGOs). Case studies of civil society response to specific environmental issues will be used to illustrate theoretical issues and assess the impacts that these actors have on environmental policy and planning.
For South Africa, finding a policy approach that balances the increasing demand for energy with the need for sustainability, equity, and climate change mitigation is a particular challenge. Through energy modelling indicators of sustainable development and policy analysis, Harald Winkler builds a rich and detailed case study illustrating how a development-focused approach to energy and climate policy might work in South Africa. Moreover, with recent recordsetting global crude oil prices, he points out that making energy supply and use more sustainable is a central challenge in South Africa's future development path. An energy researcher, IPCC author, Intergovernmental Panel on Climate Change and a member of the South African delegation to the UN Framework Convention on Climate Change, Winkler offers a nuanced examination of where the synergies and tradeoffs lie, and makes clear the imperative of considering long-term implications when meeting short-term needs.
