Polymer Liquid Crystal (PLC) and Polypropylene Interlayers in Polypropylene and Glass Fiber Composites: Mechanical Properties: Thesis or Dissertation open access
In recent developments of composite materials, scientists and engineers have come up with fibers as well as matrices for composites and techniques of blending high cost components with low cost materials. Thus, one creates cost effective composite materials that are as efficient as space age components. One of the major breakthroughs in this area is the innovation of molecular composites, specifically polymeric liquid crystals (PLCs). These materials have excellent mechanical properties such as tensile impact and bending strength. They have excellent chemical resistance, low thermal expansivity, and low flammability. Their low viscosity leads to good processability One major setback in …
Triangle: A Teaching Program of High School Geometry: Thesis or Dissertation open access
Among the early applications of computers, one can find frequent mention of intelligent instructional systems. Such intelligent instructional systems represent a new generation of learner-based computer aided instruction, preceded in time by the original frame-based systems and an intervening generation of expert-based CAI. The history of CAI is characterized by three generations: Frame-based CAI, Expert-based CAI and Learner-based CAI.
Humor and Nursing Home Residents: Thesis or Dissertation

Access: Use of this item is restricted to the UNT Community
Although humor is a generally accepted part of everyday life for humans, its existence, importance, and positive influence on older persons are often underestimated. The purposes of this study are to determine whether humor is a normal experience for nursing home residents, enhancing their activities of daily living, and whether it plays a role in contributing to their psychological well-being. The study includes a discussion of research on humor, particularly as it relates to the elderly and the aging process; analysis and comparisons based on interviews with residents on the subject of humor and review of their psychological state as …
