Hydrogen Production By The Unicellular Diazotrophic Cyanobacterium Cyanothece Atcc Sp. Strain 51142 Under Continuous Light., Hongtao Min, Louis A. Sherman

Department of Biological Sciences Faculty Publications

We report on the hydrogen production properties of the unicellular, diazotrophic cyanobacterium Cyanothece sp. strain ATCC 51142. This organism has a versatile metabolism and can grow in the presence or absence of combined nitrogen and can grow photosynthetically or mixotrophically and heterotrophically in the presence of glycerol. The strain produces a bidirectional hydrogenase (encoded by the hox genes), an uptake hydrogenase (hupLS), and nitrogenase (nifHDK). We demonstrated hydrogen production by both the hydrogenase and the nitrogenase under appropriate metabolic conditions. The highest rates of hydrogen production were produced under nitrogen-fixing conditions when cells were grown and …

Fixing Recovery: Social Capital In Post-Crisis Resilience, Daniel P. Aldrich

Department of Political Science Faculty Publications

Disasters remain among the most critical events which impact residents and their neighborhoods; they have killed far more individuals than high salience issues such as terrorism. Unfortunately, disaster recovery programs run by the United States and foreign governments have not been updated to reflect a new understanding of the essential nature of social capital and networks. I call for a re-orientation of disaster preparedness and recovery programs at all levels away from the standard fixes focused on physical infrastructure towards ones targeting social infrastructure. The reservoirs of social capital and the trust (or lack thereof) between citizens in disaster-affected communities …

Providing Availability On The Poly^2 Framework, Ankur Chakraborty

Purdue Polytechnic Masters Theses

Availability is not often a primary concern for frameworks meant to provide security. Poly^2 is one such framework. It provides us with a hardened foundation based on secure design principles to run mission-critical services. While, the primary focus of Poly^2 till now seems to have been fault isolation, we will now attempt to add recovery as well. However, current techniques may compromise the security principles on which the framework was originally built. We propose a hybrid system based on two popular techniques to rectify the same.
