An extensive review of the literature was conducted in the area of land subsidence due to the withdrawal of fluids. A method of categorizing the citations was developed to facilitate identification of references relating to specific fields of interest. A brief review of the materials represented by the bibliography indicates the state-of-the-art within this area. The bibliography (containing 1225 citations) is presented in its categorized form. 5 figs., 3 tabs.

A new passive solar thermal storage brick was developed and tested. A new insulating curtain concept was developed to assist in passive solar heating and cooling. A steel truss was designed to replace the wood truss in solar attic applications where the wood truss typically suffers some 50% loss of structural strength. Improvements were made of the dry composting toilet and grey water recycling for homes. An algae cultivation system was created for production of food, feed, fertilizer, or biomass as needed for home, farm, or industry. New concepts were explored in the areas of economy shelter, solar hot water heating, home generation of electricity, edible landscapes and other home food production, growing of fiber crops for cottage industry, storage, insulation, solar cooking, and solar refrigeration.

The economics of liquid-fuels production from microalgae was evaluated. A detailed review of published economic analyses of microalgae biomass production revealed wide variations in the published costs, which ranged from several dollars per pound for existing commercial health-food production in the Far East, to less than .05/lb costs projected for microalgae biomass for fuel conversion. As little design information or specific cost data has been published, a credible cost estimate required the conceptual engineering design and cost estimating of microalgae to liquid-fuels processes. Two systems were analyzed, shallow (2 to 3'') covered ponds and deeper (1 ft) open ponds. Only the latter was selected for an in-depth analysis due to the many technical shortcomings of the former approach. Based on the cost analysis of a very simple and low cost process, the most optimistic costs extrapolated were about $60/barrel. These were based on many optimistic assumptions. Additional, more detailed, engieering and cost analyses would be useful. However, the major emphasis in future work in this area should be on demonstrating the basic premises on which this design was based: high productivity and oil content of microalgae strains that can dominate in open ponds and which can be harvested by a …

In 1521 a band of several hundred Spaniards overthrew the Aztec empire in Mexico and its ruler, Moctezuma II. This defeat in itself created a major cultural shock for the indigenious population, but the later arrival of Spanish officials and colonists constituted a far greater if less dramatic upheaval. For the victorious Spaniards rejected Aztec governmental institutions, considering them to be distinctly inferior, and quickly substituted their own. Moctezuma II and a substantial number of the Aztec ruling class had died during the violence which accompanied the conquest and those who remained were not permitted to exercise leadership. It was, however, the stated policy of the Spanish Crown that the Indian population of New Spain should be treated with kindness, allowed to retain their property, and led gently toward acceptance of the Christian faith. Among the surviving members of the Aztec nobility were several of the emperor's children, to whom Spanish authorities accorded special attention because of their unique position. Moctezuma II's son, Tlacahuepan, who on his conversion was baptized Pedro de Moctezuma, was one who received special grants and favors, for it was the Crown's intention that members of the emperor's family should be treated with consideration and be …

The high yield potential and attractive chemical composition of Typha make it a particularly viable energy crop. The Minnesota research effort has demonstrated that total annual biomass yields equivalent to 30 dry tonnes/ha (13 tons/acre) are possible in planted stands. This compares with yields of total plant material between 9 and 16 dry tonnes/ha (4 to 7 tons/acre) in a typical Minnesota corn field. At least 50% of the Typha plant is comprised of a belowground rhizome system containing 40% starch and sugar. This high level of easily fermentable carbohydrate makes rhizomes an attractive feedstock for alcohol production. The aboveground portion of the plant is largely cellulose, and although it is not easily fermentable, it can be gasified or burned. This report is organized in a manner that focuses on the evaluation of the management options task. Results from stand management research performed at the University of Minnesota during 1982 and 1983 are integrated with findings from an extensive survey of relevant emergent aquatic plant research and utilization. These results and findings are then arranged in sections dealing with key steps and issues that need to be dealt with in the development of a managed emergent aquatic bio-energy system. A …

This investigation traces the history and development of music theory in Mexico from the date of the first Mexican treatise available (1776) to the early second half of the nineteenth century (1866). This period of ninety years represents an era of special importance in the development of music theory in Mexico. It was during this time that the old modal system was finally abandoned in favor of the new tonal system and that Mexican authors began to pen music treatises which could be favorably compared with the imported European treatises which were the only authoritative source of instruction for serious musicians in Mexico.
