High temperature concrete for nuclear reactors
… response of concrete to high temperatures for extended periods, such as those that may be experienced in a normally operating nuclear reactor.

The Effect of Exposure to Aversive Stimuli on Activity Based Anorexia
… to participate in physical activity for extended periods of time. These experiments address whether exposure to aversive stimuli during baseline and limited food access with running wheel access (ABA) phases influences weight loss in the ABA procedure. In the first experiment, twentyseven …

Behavioural and Neuronal Correlates of Long-term Contextual Memory for Cocaine: Relevance to Craving and Relapse
… it occurred maintained in long-term memory after extended periods of abstinence? (2) Are regions of the mesocorticolimbic circuitry, namely the nucleus accumbens and amygdala, differentially activated by retrieval of Pavlovian conditioned associations as time passes after cocaine experience? (3) …

Analysis, design, and control for robots in temperature-restricted environments
… control to maintain robot operation for extended periods of time. A control system based on system model linearization and model predictive control was implemented for the TMS. The results of the closed-loop simulations indicate that the control system enhances the operation of the TMS, …

NEUROMUSCULAR PERFORMANCE ASSESSMENTS AND MONITORING IN COLLEGIATE NCAA DIVISION I BASKETBALL ATHLETES: AN ADOPTION OF THE APPLIED RESEARCH MODEL FOR THE SPORT SCIENCES
… training exposure, especially, when studied over extended periods of time. Therefore, the overarching aim of the current work is to study neuromuscular performance as quantified via force-plate derived measures of vertical jump performance in collegiate NCAA division 1 basketball players, deriving …

Task flow: A novel approach to fine-grain wafer-scale parallel computing
… Each task may remain local to one cell for extended periods or may flow between cells with as few as one instruction executed in each cell.

Using a bio-inspired model to understand the evolution of the remora adhesive disk
… compliant bodies under high shear conditions for extended periods of time. This research addresses the lack of underwater adhesives by using remora adhesion as a bioinspired model. Evolution has taken part on this family of species, allowing them to have a biologically advanced suction cup …

Selected modifications of the auditory feedback system and their effects on speech fluency.
… speech performance over extended periods. There is clearly a close relationship between speech self-monitoring integrity and overall speech performance; therefore, we will examine the feedback configurations more closely.

Transplant organ preservation cooler
A method for preserving transplant organs for extended periods of time has been developed in the transplant organ preservation cooler. The preservation cooler enhances organ viability by maintaining a temperature controlled organ bath and pumping perfusate through the transplant organ. The emphasis …

Effect of concentrations of progesterone on follicular development and fertility in beef cows
… decrease fertility to the same extent seen with extended periods of low progesterone.

An Eulerian-Lagrangian finite element method for modeling crack growth in creeping materials
… that are exposed to high temperatures over extended periods, such as nuclear power plants and gas turbines. This study is concerned with the development of finite element solution methods for the analysis of quasi-static, ductile crack growth in history-dependent materials. The mixed …

Design of an adventitial type reinforcement of prosthetic vascular grafts through mechanically affirmed material and structure modulation
… diameter synthetic grafts remain patent for extended periods due to high flow rate, while smaller diameter grafts occlude more readily. Mechanical property mismatch between graft and host artery has been cited as one of the major factors that contribute to graft occlusion. It has thus been …

Hydropedology of Problematic Interfluve Transported Soils in the Central Virginia Piedmont
… Residual soils did not perch water for extended periods; and were saturated for significantly (p<0.001) shorter durations and shallower depths (average 93 and 82 cm for 30-day and 20-day oxyaquic criteria, respectively). Transported soils under clear cuts had significantly (p<0.001) …

An Analysis of Intention Formation as a Function of Prospective Memory in Air Traffic Controllers
… that taxes their memory resources for extended periods of time rely on this type of memory. Controllers objectives often change based on incoming information and the amount of traffic they are controlling. It is important to investigate how controllers form intentions for future events, …

A Wearable Device to Inform Pressure Injury Prevention Support Surfaces Selection and Design
… manage for wheelchair users, who have to sit for extended periods of time, up to 10-12 hours per day. Measuring the interface pressure between support surfaces and the body can assist in selecting surfaces that minimize the pressure to prevent pressure injuries from developing. However, pressure …

Cortical recording with conducting polymer electrodes
The ability to record from the same neuron for extended periods of time is essential to understanding how the brain reorganizes during motor learning. Conventional chronic recording microelectrodes are made from metal or silicon. However, the large stiffness mismatch between the electrodes and …
