Linear patterns in background mostly in whites and grays layered with small geometric shapes in multi-hues with Mickey Mouse cartoon character emerging from the lower edge.

"This report presents the results of the pre-impoundment investigations" of Ray Roberts Lake. The purpose of the study is "to improve understanding of the impact of [U.S. Army Corps of Engineers] water resource projects, to provide the basis for evaluating the projects' effects on fish and wildlife resources, and to provide the opportunity for better planning and development of water resource projects and natural resource management" in the Lake Ray Roberts area, located in Denton County, Texas (p. 3).

This volume of the report represents the technical findings of a study conducted on the ecological makeup of the Trinity River. The data presented includes: ambient toxicity test results and survival rates, United States Geological Survey (USGS) flow data, water quality data, as well as sediment quality data.

This report describes the findings of a study conducted on the watersheds of "Lake Lewisville, Lake Ray Roberts, Lake Grapevine and the Elm Fork of the Trinity River between Lake Lewisville and Frazier Dam," which are all part of the upper Trinity drainage basin (p. 31). The study examines the potential benefit of "remote sensing and geographic information systems (GIS) for watershed management" in and around Dallas, Texas (p. i).

This report describes the findings of a study conducted on the Eastern Watersheds of Lake Lavon, Lake Ray Hubbard, Lake Tawakoni, Lake Palestine and Lake Fork, which are located within the Blackland Prairie, Post Oak Savannah and Pineywoods provinces. These watersheds are among nine that provide drinking water to Dallas, Texas. The study examines the potential benefit of "remote sensing and geographic information systems (GIS) for watershed management" in these five watersheds (p. iii).

This report describes archaeological testing at a site known as Fort St. Leon in Louisiana. Studies were made of levee building, geomorphology, and comparison of archival maps and aerial photographs, which contribute to the understanding of human activity as well as geological processes at the site.

This book examines the social and philosophical attitudes in Western culture that relate to the environment including aesthetics, wildlife, and land use. Both the historical significance and a framework for further discussions of environmental ethics are discussed in the book.

Article discussing research on the estimated effect of an injury on a worker's life expectancy, worklife expectancy and discounted expected income.

This article discusses urban water demand estimates under increasing block rates.

This article discusses input substitution in irrigated agriculture in the high plains of Texas.

This doctoral dissertation discusses access to film and video works. Physical and intellectual access to moving image documents is insufficient, often insignificant, at the level of the individual user. Existing access tools suffer from a lack of recognition of the differences between linguistic text communication and image communication. Browsing and relevance judgements are made difficult by the physical realities of film and video documents - one cannot flip through them - and by the habits of serial and passive viewing.

In this pamphlet, the author will examine some of the benefits of chemicals to mankind. The author also will examine some of the problems chemicals have caused, are causing and may cause in the future.

This pamphlet discusses merit pay for teachers. In most societies, the acquisition of money is a symbol of success. The present supply as well as the quality of public school teachers in the United States is directly related to the salaries that are paid to teachers as compensation for services rendered. How much to pay teachers for their services, who should be given merit pay, and how a pay plan should be administered are the focal points of an issue that promises to promote debate in the forthcoming presidential election.

This report is on a case study from Guatemala on malnutrition and food aid programs. The purpose of this study is to examine the impact of food aid and/or food aid programs on the nutritional status of its recipients in two regions of Guatemala. From this investigation, empirically-based programmatic statements as to the role of food aid and its impact on human society will be presented.
