Background and significance: Even with the advent of direct bonding, decalcification remains a problem in orthodontics today. Glass ionomer cements have been used in dentistry for fluoride release for years and may have beneficial use in...
Supervisory control systems--Security measures; Automatic data collection systems--Security measures; Drinking water--Security measures; Computer networks--Security measures
Supervisory control and data acquisition (SCADA) systems are used by many critical infrastructures including electric power production and distribution, water and waste water treatment, rail transportation, and gas and oil distribution. Originally...
INTRODUCTION: Attention Deficit/Hyperactivity Disorder (ADHD) is a disorder that is prevalent throughout the world. It is believed that 5% of school aged children suffer from ADHD, with some estimates indicating as high as 10% may suffer from the...
Mathematics teachers--Training of; Student teaching; Mathematics teachers--In-service training
Teacher candidates enter teacher preparation programs with grounded beliefs
about teaching and learning. These beliefs are especially problematic in the area of
mathematics, as they hinder instructional decisions (Karp 1988, 1991; Kolstad &...
Data libraries--Security measures; Computer networks--Security measures; Information storage and retrieval systems; Digital preservation
Data centers (DC) are the core of the national cyber infrastructure. With the incredible growth of critical data volumes in financial institutions, government organizations, and global companies, data centers are becoming larger and more...
Electroencephalography; Visual evoked response; Drug addicts--Research
In 2006 it was estimated by the Substance Abuse and Mental Health Service Administration (SAMHSA, 2007) that 19.9 million Americans used illicit drugs, computing to roughly 8.0 % of the United States population. In 2007, there were 2.1 million...
Computer chess; Chess--Computer programs; Games and technology; Computer networks--Security measures
Cheating in chess can take many forms and has existed almost as long as the game itself. The advent of computers has introduced a new form of cheating into the game. Thanks to the computational power of modern-day computers, a player can use a...
A wireless sensor network consists of a large number of low-power nodes equipped with wireless radio. For two nodes not in mutual transmission range, message exchanges need to be relayed through a series of intermediate nodes, which is a process...
Spinal cord--Wounds and injuries; Stretch (Physiology)
An increasing amount of healthcare resources is used for the treatment and prevention of contractures in patients with spinal cord injury (SCI), with stretch and passive movements remaining the most prominent intervention methods. The results of...
African American men--Employment; African American men--Attitudes; Mentoring in business; Job satisfaction
This dissertation is a correlational designed study that examined the strength and direction of the relationship between mentoring, job satisfaction, and organizational commitment, of African American men, exclusively in a business setting (N =...
Integration of the Internet with a Cellular Network, WMAN, WLAN, and MANET presents an exceptional promise by having co-existence of conventional WWANs/WMANs/WLANs with wireless ad hoc networks to provide ubiquitous communication. We call such...
This dissertation focuses on the mechanisms and implications of perceptual learning of binocular interactions. Perceptual learning is an important means of adapting to the changing environment, demonstrating the possibility of neural plasticity in...
Science teachers--Certification; Science--Study and teaching (Elementary)
The purpose of this study was to discern what differences exist between the science inquiry learning environments created by National Board Certified Teachers (NBCTs) and non-NBCTs. Four research questions organized the data collection and...
Sensor networks are just in their infancy. Their use will continue to grow as the technology becomes cheaper and more efficient. A current shortcoming with sensor networks is the inability to efficiently provide secure communications. As sensor...
This study examined the effect on physician/nurse collaboration and
communication of the implementation of the SBAR protocol, used as nurses reported
patient changes to physicians, in a Midwestern community hospital ICU. The design was
a two-phased...
Heart--Hypertrophy; Hydrogen sulfide--Therapeutic use
Background: Although matrix metalloproteinase (MMPs) and tissue inhibitor of metalloproteinase (TIMPs) play a vital role in tumor angiogenesis and TIMP-3 causes apoptosis, their role in cardiac angiogenesis is unknown. Interestingly, a disruption...
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...
This research project describes the application of a master/slave configuration of processors to study a comparison of alternative material handling configurations for automated manufacturing. Such a study usually requires a large number of...
