PREHISTORIC AGRICULTURAL ADAPTATION AND SETTLEMENT IN LONG HOUSE VALLEY, NORTHEASTERN ARIZONA.

HARRILL, BRUCE GILBERT. January 1982 (has links)
A recently completed intensive archaeological survey of Long House Valley in northeastern Arizona has provided a detailed body of data on prehistoric settlement distribution and environmental variation. Long House Valley was occupied between A.D. 1 and 1300 by prehistoric agriculturalists referred to as the Kayenta Anasazi. This study examines the changing relationship between settlement locations and agricultural adaptations from A.D. 500 to 1300 in Long House Valley. As part of this analysis, the archaeological, ethnographic, and environmental background of the Kayenta region is reviewed as a basis for understanding the nature of agricultural adaptation in this region. Agricultural practices of the Hopi Indians of northern Arizona provide the basis for a model of probable agricultural field locations. This combined with an examination of the physiographic, hydrographic, and edaphic features in the valley allow identification of potential field areas. Changes in the potential of identified field areas are postulated on the basis of variation in available moisture as determined from a regional dendroclimatic reconstruction. Prehistoric habitation site locations and their changing distribution through time are examined against these proposed changes in field potential. This study demonstrates that there is a distinct positive correlation between settlement location and potential field location as determined by available moisture. Beginning about A.D. 1150 deteriorating environmental conditions in the form of decreased moisture, arroyo cutting, and lowered water table are considered the primary determinants of changes in site locations. These changes are viewed as an adaptive response by the Kayenta Anasazi to conditions of decreased moisture. Continuing deterioration of the environment made the practice of agriculture impossible and resulted in the total abandonment of Long House Valley and the entire Kayenta region by A.D. 1300.

Early nineteenth century construction techniques along Indiana's eastern National Road (1830-1850)

Molnar, Katherine J. January 2007 (has links)
This thesis argues that early nineteenth-century domestic architecture along Indiana's eastern National Road (Wayne, Henry and Hancock Counties) was a product of the available local materials, not a product of cultural influences traveling along the Road. While the first chapter drives in this point, the second and third chapters describe the local materials (builders and carpenters, wood, saw-mills, clay, brickmaking and limestone), and explain construction techniques in a series of case study buildings. The thesis concludes by not only confirming the proposition, but also by making a few conclusions regarding early nineteenth-century construction methods. / Department of Architecture

Overheated or Stable? : An Analysis Ff The Swedish Housing Market

Otterström, Oscar, Vahlberg, Niclas January 2010 (has links)
The Swedish housing market has been subject to extensive attention in the media recently, and the existence of a housing bubble has been questioned. The purpose of this thesis is to analyse the Swedish housing market to investigate if there are reasons to believe that the market is overvalued. The current situation in the housing market will be compared to the United States market prior to the crash of 2007. The models that are used in the paper is the house price-to-income, price-to-rent and imputed rent-to-rent. Other fundamental factors such as rent control, household debt, interest rates, and other policies effecting the housing market will be discussed. The main findings indicate that the Swedish housing market in 2010 is overvalued, however one has to consider that there are limitations to these models such as the extra benefits of owning a house compared to renting.

Intenzivní dům v Brně / Intenzive Urban Housing Brno

Jabůrková, Dominika January 2016 (has links)
The aim of this Master thesis was to create urban structure situated in the particular resident area of Brno city centre. The solution offers mixing of different functions (living, shopping, workshops, offices, restaurant, other services and working possibilites) on a relative small built up area.This is realized with a help of two main principes/multiplicity and verticality. The efective use of the area was achieved with dividing the space to the „calm“areas and „busy“ areas. Calm areas are a park in courtyard and the roof gardens, busy area is a new diagonál street with shops, restaurant, fastfood and galery. The objects have different height, the highest one is 12 floors tall. In the first one are different functions as kindergarten, shops, administrative, gallery, insurance, coffee, in the second one there is partly administrative and infant school. Flats and studios are designed from the second floor to the 11 floor. The 12th floor offers a coffeebar with a view of Brno dominants. There is parking and technical device space in the two underground floors. The construction system is reinforced concrete monolitic skelet with girders, the horizontal constructions are reinforced monolitic plates. The buildings are founded on reinforced concrete flaps.

The role of retrotransposons in gene family expansions: insights from the mouse Abp gene family

Janousek, Vaclav, Karn, Robert, Laukaitis, Christina January 2013 (has links)
BACKGROUND:Retrotransposons have been suggested to provide a substrate for non-allelic homologous recombination (NAHR) and thereby promote gene family expansion. Their precise role, however, is controversial. Here we ask whether retrotransposons contributed to the recent expansions of the Androgen-binding protein (Abp) gene families that occurred independently in the mouse and rat genomes.RESULTS:Using dot plot analysis, we found that the most recent duplication in the Abp region of the mouse genome is flanked by L1Md_T elements. Analysis of the sequence of these elements revealed breakpoints that are the relicts of the recombination that caused the duplication, confirming that the duplication arose as a result of NAHR using L1 elements as substrates. L1 and ERVII retrotransposons are considerably denser in the Abp regions than in one Mb flanking regions, while other repeat types are depleted in the Abp regions compared to flanking regions. L1 retrotransposons preferentially accumulated in the Abp gene regions after lineage separation and roughly followed the pattern of Abp gene expansion. By contrast, the proportion of shared vs. lineage-specific ERVII repeats in the Abp region resembles the rest of the genome.CONCLUSIONS:We confirmed the role of L1 repeats in Abp gene duplication with the identification of recombinant L1Md_T elements at the edges of the most recent mouse Abp gene duplication. High densities of L1 and ERVII repeats were found in the Abp gene region with abrupt transitions at the region boundaries, suggesting that their higher densities are tightly associated with Abp gene duplication. We observed that the major accumulation of L1 elements occurred after the split of the mouse and rat lineages and that there is a striking overlap between the timing of L1 accumulation and expansion of the Abp gene family in the mouse genome. Establishing a link between the accumulation of L1 elements and the expansion of the Abp gene family and identification of an NAHR-related breakpoint in the most recent duplication are the main contributions of our study.

Troy Novant: An Examination of Aeneas as Depicted by Geoffrey Chaucer

Steffensen, Peter 09 August 2016 (has links)
This thesis examines the ways in which historical, cultural, and literary influences have changed the way that Chaucer portrayed Aeneas in both The Legend of Good Women and The House of Fame. The primary texts looked at in comparison are Ovid's Heroides, Virgil's Aeneid, and the historical works of Dares and Dictys. This study concludes that this complex network of forces caused Chaucer to present Aeneas as an overall negative figure in his poetry.

Assessing the performance of combined sustainable drainage and ground source heat devices in a domestic building

Faraj, A. January 2013 (has links)
A field study of the feasibility and the performance of a sustainable drainage technique combined with a renewable energy device to provide heating in a domestic setting was carried out from March 2008 to November 2010 to acquire practical data about the system’s operation. Among all the sustainable drainage techniques, permeable pavement system (PPS) was selected to be applied in this project since this particular technique can be used for driveways and car-parking hard standings, but more specially they can be designed as a tanked system whereby an impermeable membrane is installed at the bottom of the tank in order to hold the rainwater collected as runoff from hard areas and roofs before releasing it in a controlled manner. The renewable energy device applied in this study is a ground source heat pump system (GSHP), which has been found in previous studies to provide a better performance when installed in wet conditions. Based on this, the PPS and the GSHP with horizontal ground heat exchanger (GHE) were integrated in a 350mm deep reservoir under ‘real life’ conditins. The combined system operated in heating mode in a family–sized, three bedrooms detached EcoHouse at the Building Research Establishment Innovation Park, Watford, UK. Monitoring the combined system included taking measurements of the temperature of the conditioned space, the ground around the PPS/GSHP system, and of the ambient air every 10 minutes. Assessing the performance of the PPS/GSHP system involved investigating the effect of extracting heat via the GHE on the ground temperature, the impact of the PPS/GSHP on the thermal profile of the air above the surface of the reservoir, and computing the PPS/GSHP coefficient of performance (CoP). The thesis includes information about the design of the PPS/GSHP system including the structure of the sub-base, types and size of the used aggregate and stone, the depth of the excavated reservoir amongst others, also the technical problems that materialized, largely due to the fact that the PPS/GSHP was installed and operating under real-life circumstances. Results obtained from the study provided evidence for the workability of the combined system in regards of stormwater management and of providing heat to the EcoHouse. However, monitoring the rainwater stored in the reservoir showed that, due to leakage, the top part of the buried coil was not covered with water. The monitoring also revealed that the rainwater surrounding parts of the coil was, in severe weather, frozen. Moreover, highly significant correlations (p<0.01) were calculated for the ambient air and the ground temperature relationships with the CoP. All of these factors resulted in a 1.8 coefficient of performance being obtained. This low figure was related to the shallow depth of the reservoir since it became clear that its ground temperature was greatly influenced by the ambient air temperature. The study also revealed that the evaporation process was prevented from occurring due to the Inbitex™ composite layer, as a result there was no significant effect on cooling the thermal profile of the air near the surface of the pavement. Furthermore, it was concluded that continuous heat extraction from the ground contributed to an underground temperature drop.
