- Description:
- The purpose of this study was to select an alloy with a low driving force for nucleation for a more in-depth study of the nucleation of γ’-precipitates. To do this, three Ni-Cr-Al alloys were chosen close to the solvus line of a Ni-Cr-Al phase diagram, ensuring low supersaturation and therefore...

- Description:
- Nitrogen (N) deposition can alter belowground microbial communities, especially ectomycorrhizal (ECM) fungi, resulting in a reduced ability of associated trees to access organic nutrients. This study tested whether N addition decreases ECM species richness and shifts ECM species composition across spatial scales in a subtropical slash pine (Pinus elliottii) plantation...

- Description:
- Magnetic Resonance Imaging is a non-invasive modality that allows for deep-tissue imaging. Contrast agents decrease image acquisition time and increase the intrinsic contrast between different types of tissue. A new family of enzyme-activated contrast agents is emerging that has the ability to report on enzymatic processes in vivo. Towards this...

- The proper distribution of cellular organelles and protein complexes is important for maintaining cellular organization and function. Transport in eukaryotic cells requires three motor proteins, kinesin, dynein, and myosin, attached to specific cargoes mostly by adaptor proteins. This work focuses on the mechanism of microtubule-dependent organelle transport in vivo. This...

- Description:
- Early Growth Response genes (Egr1-4) are transcriptional mediators of signals governing growth and differentiation. In sympathetic neuron-derived cell lines, Egr1 is induced by NGF signaling, which is required for sympathetic neuron survival, differentiation and target organ innervation. In the absence of identifiable sympathetic defects in Egr1-deficient mice, we investigated the...

- Risk measurement involves estimating some functional of a loss distribution. This calls for nested simulation, in which risk factors are sampled at an outer level of simulation, while the inner level of simulation provides estimates of loss given each realization of the risk factors. Assessing the statistical uncertainty of estimates...

- Beginning in the 1960s, U.S. federal law required ongoing and systematic planning as a condition of federal transportation funding. An ad-hoc system for forecasting future travel, which has come to be referred to as the "four-step" procedure, quickly became established as the ubiquitous analytic tool for transportation planning. The four-step...

- To increase the butanol titers and selectivity in <em>Clostridium acetobutylicum</em> we replaced the promoter of the alcohol/aldehyde dehydrogenase (<em>aad</em>) gene with the phosphotranbutyrylase (<em>ptb</em>) promoter and combined this with CoAT downregulation to minimize acetone production. This led to early production of high alcohol (butanol plus ethanol) titers and overall solvent...
