Sediment Bound Trace Metals in the White Rock Creek Watershed, Dallas and Collin Counties

Description: Areas were sampled in the White Rock Creek Watershed to examine sediment bound trace metal distributions and sorption relationships. A Kruskal-Wallis AOV found significant among area differences for most metals, and SNK-like multiple comparisons were used to group these areas. Kruskal-Wallis AOVs similarly found among area differences for sediment components that bind trace metals (Fe and Mn oxides and organic carbon) and physicochemical conditions that influence metal sorption (particle size and pH). Multiple correlation found numerous relationships among trace metals, sediment components, and physicochemical conditions. Statistical relationships indicate that metal partitioning to various sorption factors is metal specific. White Rock Creek Watershed trace metal concentrations are comparable to those in many urban watersheds.

A Survey of Singers: Is Mental Imagery Used in the Conceptualization of Pitch and Vowel?

Description: Mental imagery is a common theme in research that clarifies how musical thought relates to musical performance. Unfortunately, minimal information exists regarding mental imagery and singers. The purpose of this study was to probe the role, if any, mental imagery plays in the conceptualization of pitch and vowel. By interviewing singers at differing levels of expertise, basic information was obtained about the mental processes used by singers. Through evaluations of the singers' mental processes, it was concluded that 95% of the singers in the study employed mental imagery. All singers described using kinesthetic imagery, while the majority implemented sensory and auditory imagery. Viso-spatial imagery was implemented among the more experienced singers. The majority of singers also reported: imaging pitch and vowel interactively; imaging from an internal perspective; and utilizing mental rehearsal. Less than half of the singers described using methods other than mental imagery to conceptualize pitch and vowel.

Electricity in Rural Areas of North Texas

Description: "This study shows three things: (1) a precedent for the expenditure of public funds to teach electricity in our public high schools has already been established by the school system in the larger school systems of Texas, (2) the rural families living on electrified farms in the North Texas area want instruction of this type given to the boys and girls in their communities, and (3) both the rural people and the professional people of the North Texas area believe that instruction dealing with the use of electricity and electrical equipment had spread until by 1935 more than twenty-one million homes, about eighty percent of the total in America at that time, were electrified, only eleven American farms out of every 100 had central-station electricity. More than five million American farms lacked electric service. "--leaf 50.
