The field of bone densitometry has grown rapidly, particularly in the past 15 years. Many techniques are now available from which the physician may choose. The focus of this research is on Dual-Energy X-Ray Absorptiometry (DXA) and Quantitative...
The Knudsen pump works on the principle of thermal transpiration. As a result of requiring a thermal gradient, channel hydraulic diameter smaller than the mean free path of the gas being pumped, and having no moving parts, the Knudsen pump features...

Hind limb paralysis may occur in dogs for a variety of neurological or musculoskeletal reasons. For dogs with limited mobility their lack of ability to ambulate can have a great impact on their physical and mental health. Canine wheelchairs can...
The heat pipe augmented solar wall operates much more efficiently for domestic air heating than alternative passive solar technologies. The thermal diode effect of heat pipes reduces the insulating losses of the unit during nighttime and adverse...
Heat pipes; Solar heating--Passive systems; Solar heating--Research; Solar energy--Research
The one dimensional heat transfer, thermal diode effect of heat pipes makes
them ideal for passive solar applications. Gains in a heat pipe passive solar wall are not
lost during cloud cover or periods of low irradiation. An experimental model was...
Background - Cranial cruciate ligament (CrCL) rupture in the canine stifle is a leading
cause of orthopedic lameness in the dog. Several corrective surgical procedures have
been developed to return dogs to pre-injury function following CrCL...
This thesis looks at the optimization of fluid flow and mass transfer using computational fluid dynamics (CFD) in a micro fluidic coulter counter. CFD will be used to solve equations of fluid flow and mass transfer to see how molecules within the...
Previous experimental studies on static, bio-inspired corrugated wings have shown that they produce favorable aerodynamic properties such as delayed stall compared to streamlined wings and flat plates at high Reynolds numbers (Re ≥ 4x104). The...
Athletic shoes; Foot--Wounds and injuries--Prevention
The purpose of this investigation was to determine if cycling shoes made with stiff material cause an increase in peak plantar stress over shoes with less stiff material. Shoe stiffness measurements were collected under controlled conditions and in...
Ligaments--Wounds and injuries; Knee--Wounds and injuries; Women athletes--Wounds and injuries
Anterior Cruciate Ligament (ACL) injuries are among the most common injuries incurred by both recreational and professional athletes. ACL injuries often occur during popular contact sports like basketball, football, volleyball and baseball, and...
Cardiology--Research--Methodology; Microfluidics--Equipment and supplies
Cardiovascular disease (CVD) is the leading cause of death in the United States and accounts for nearly 1,372,000 deaths each year. In addition, ~81 million Americans suffer from some form of CVD. Understanding the molecular basis of various...
Knee--Mechanical properties; Knee--Pathophysiology; Gait in humans; Osteoarthritis
Osteoarthritis (OA) of the knee is associated with decline in functional capacity and ultimately leads to Total Knee Arthroplasty (TKA) in many of these patients. Exercise regimens prior to surgery may potentially enhance pre and post TKA...
The application of carbon nanotubes (CNTs) has captivated the curiosity of today's experts due to the escalating potential in the field of electronic detection of biomolecules. Their extreme environmental sensitivity and small size make them ideal...
Vertical axis wind turbines (VAWTs) are devices to convert wind energy into electricity. Unlike horizontal axis wind turbines (HAWT) where the main rotor shaft is set horizontally, VAWTs use vertical rotor shaft. Unlike HAWTs, VAWTs can be...
In this thesis self-assembled growth of Ag2Ga nano-needles on batch fabricated
micro-grippers are reported. The room temperature growth of Ag2Ga nano-needles have
been recently developed as stylus for Atomic Force Microscopy (AFM). Integration...
Falls (Accidents); Children's accidents; Children--Wounds and injuries; Child abuse--Investigation
Pediatric short-distance falls, especially from beds or other furniture, are common
false histories given by caretakers to cover up abusive trauma. However, short-distance
falls are also a common occurrence in young children. Knowledge of the types...
In order to satisfy customer expectations, a ground vehicle must be designed to meet a broad range of performance requirements. A satisfactory vehicle design process implements a set of requirements reflecting necessary, but perhaps not sufficient...
Ground-level ozone forecast models were developed for the following middle and small metropolitan areas in Kentucky: Ashland, Bowling Green, Owensboro, and Paducah. These models were nonlinear regression models, based on models previously developed...
Simplified modeling generates a great deal of interest in the area of crashworthiness analysis. Modeling methods used to create simplified computer models for crashworthiness have been well developed. In advanced simplified models, researchers...
A combination of three techniques – high resolution micro computed tomography (micro CT) scanning, Archimedes-based volume fraction measurement and serial sectioning or milling – were used to determine the volume fraction, trabecular thickness,...
