Quantitative Analysis of Water and Biological Samples for Determination of Haleogenated Organics in the Upper Trinity River, Texas : Final Technical Report

Description: This study had three objectives: 1) to develop a method for the quantitative determination of total organic bound chlorine in water and biological samples using Source-Excited X-Ray Fluorescence, 2) to provide training in the use of analytical techniques for students from different disciplines, and 3) to use an interdisciplinary approach involving students of biology, chemistry, and physics to investigate a complex environmental problem. Only the first objective is treated in detail in this volume.

Visual Perception During Naturalistic Near-Death Out-of-Body Experiences

Description: Study attempting to ascertain the most appropriate content and placement of visual stimuli in a hospital-based study of the veridicality of out-of-body perception in the near-death experience (NDE), and the likelihood that a subject in such a study would notice, clearly perceive, and accurately recall a visual stimulus.

Unexpected Findings in a Study of Visual Perception During the Naturalistic Near-Death Out-of-Body Experience

Description: Study of visual perception during the naturalistic near-death out-of-body experience (nND OBE), that aspect of the NDE in which the experiencer seems to view normal physical surroundings from a vantage point outside the physical body, which yielded some unexpected findings that contradicted or augmented previous research. Each of these findings is discussed relative to previous research and analyzed in light of the limitations of the current study.
