Substrate-supported-phospholipids bilayers (SSPB) could be utilized to stabilize functional membrane proteins on solid surfaces while providing an ideal medium to mimic the many properties of biological membranes. Our approach to the fabrication of SSPB relies on the property of phospholipids to self-assemble inside Anodic Aluminum Oxide (AAO) nanoporous substrates into....

Aluminum tolerance of soybean [Glycine max (L.) Merr.] by citrate secretion from roots, leading to external complexation of toxic Al species in solution, is enhanced by addition of μM Mg2+ to hydroponic solutions. The objectives of this dissertation were to assess ameliorative effects of μM Mg additions on soybean root growth in acidic subsoils and to r....

Simulator technology for the high dynamic range, electrothermal modeling of electronic circuits is developed and applied to digital, radio frequency (RF) and microwave circuits. High-dynamic range is achieved using a combination of device models based on state-variables and utilizing automatic differentiation, precise error determination, and time step control. State-va....

Towards developing a robust finite element simulation model, this dissertation determines the state-of-the-art of simulation of ratcheting responses of structures. With this objective, the study evaluated seven constitutive models for their ratcheting simulation capabilities for straight pipe and elbow pipe components. Both local (strain ratcheting) and global (e.g., lo....

Plugs should be transplanted at the pullable plug stage (PPS), which is when the root ball holds together after removal from the plug flat. If seedlings are held in plug flats for too long after PPS, they may not return to a normal growth rate after transplanting. This may be due to several factors including nutrient deficiency, hormone deficiency, low oxygen availabili....

Session Initiation Protocol (SIP) is fast emerging as the next generation signaling protocol. It operates independently of the underlying network transport protocol, establishing sessions between multiple users irrespective if the media is voice, data or video. It is projected to eventually replace the existing multiple voice and video signaling protocols as a single pr....

The prevalence of obesity is increasing worldwide. In fact, in the United States, obesity has been recognized as an epidemic. Obesity has been shown to increase the risk of physical injury and illness. Among these physical disorders, low back pain (LBP) is one of the most common phenomena in both obese and non-obese individuals. However, the relationship between obesity....

Conventional superscalar processors recover from a mispredicted branch by squashing all instructions after the branch. While simple, this approach needlessly re-executes many future control-independent (CI) instructions after the branch's reconvergent point. Selective recovery is possible, but is complicated by the fact that some control-independent instructions must be....
