A Ten-Millennia Lens: Landscape, Culture and History at Russell Cave National Monument

English, Jesse Randall 12 May 2012 (has links)
Developed out of a need for a reliable methodology of documenting historic landscapes, the National Park Service uses Cultural Landscape Reports to determine the significance and integrity of historic landscapes. Treatment recommendations developed from an analysis of site history and existing conditions guide the management decisions of cultural landscapes. Russell Cave National Monument, located in Bridgeport, Alabama, contains one of the oldest continuous archeological records in North America. A cultural landscape report for the park had not yet been completed. This research consists of a historical narrative covering the 10,000 years of human occupation in the cave, a documentation of existing conditions, an analysis of historic integrity, and recommendations for management, preservation, and restoration of the landscape.

The Settlement of Union Park, Hamilton 1900 - 1940: A Study using Tax Assessment Records

Begadon, Stephen 04 1900 (has links)
This research paper describes a working-class suburban neighborhood for the pre-WWII period 1900-1940. The data are accumulated from tax assessment records, as these are extremely accurate and contain a large variety of information suitable for this study. The main objective is to describe the characteristics of Union Park in Hamilton, Ontario, using the years 1911, 1921 and 1931 as representative of the time period. Three areas of concern were focused on: the occupational characteristics of the inhabitants, describing the inhabitants homes based on building values, and determining characteristics of construction in the area as either owner-built or speculatively built. In general the results show that the area was predominantly working-class, the homes were very cheap in relative value and that the area was primarily owner-built for the period of study. Interesting variations were observed and possible reasons for such variations are suggested. / Thesis / Bachelor of Science (BSc)

The Effect of Subsurface Hydrology on DDT Degradation in Soils at Point Pelee National Park, Ontario, Canada

Marenco , Nadia 09 1900 (has links)
<p> Systematic soil sampling and analyses provided DDT, DDE and DDD, organic and mineral matter concentrations, as well as various soil physical and hydraulic properties from three study sites at Point Pelee National Park. A soil's physical properties, soil and water management practices, and DDT application history, can affect DDT degradation and change the relative amount of its metabolites. DDD is the principal product of the dechlorination of DDT in high moisture content, reducing anaerobic soil environments. The main degradation product in soils under aerobic conditions is DDE. %DDT, %DDE and %DDD abundances used in conjunction with soil environment characterization data, can be used to indicate not only whether DDT is degrading, but what environmental factors are controlling its degradation. At the Park, DDT is primarily lost from the soil by microbial degradation to DDE and DDD. %DDT, %DDE and %DDD ratios from each study site indicated that wetter more organic-rich soil environments degraded DDT to its metabolites at a faster rate than drier less organicrich soils. Moreover, historical water level data was used to illustrate that this wetter study site was flooded for part of the year when adjacent marsh water levels were high. These conditions resulted in the accumulation of organic matter over time and the creation of alternating anaerobic/aerobic conditions in the soils resulting in an increased rate of degradation of DDT in these areas. Based on the relative %DDT in the soils at each study site, relative half-life estimates for the first order decay of DDT to its metabolites DDE and DDD were calculated. Half-life estimates for DDT at the wettest and most organic-rich study site range from 6 to 8 years; significantly lower than the two other study sites, which range from 15 to 30 years and are on the high end of the range reported in the literature.</p> / Thesis / Master of Science (MSc)

Remediation of DDT Contaminated Soil: A Field Study

Badley , Joanne 07 1900 (has links)
<p> Point Pelee National Park in Leamington, Ontario, Canada contained a large component of private farming and recreation until the 1960's. DDT was applied at the park as pest control in the orchards and recreational areas between 1948 and 1960. Recent studies have shown that the compounds DDT, DDE and DDD are highly persistent in the shallow soils of Point Pelee National Park. A laboratory treatability experiment has been effective in the removal of DDT, DDE and DDD from columns packed with soil collected from Point Pelee National Park, using hydroxypropyl-ß-cyclodextrin. Cyclodextrins are microbially produced cyclic oligosaccharides which have a unique hydrophilic shell and a hydrophobic cavity. They are able to form inclusion complexes and aid in the transport of relatively insoluble compounds. A pilotscale field remediation experiment involving the application of hydroxypropyl-ß-cyclodextrin to a Random Latin-Squares design was completed at Point Pelee National Park over the course of five months. Systematic soil sampling and analyses provided DDT, DDE and DDD concentrations throughout the remediation experiment in order to assess the removal efficiency of hydroxypropyl-ß-cyclodextrin. In-Situ volumetric moisture content was monitored throughout the study with a TDR based system. Systematic soil sampling and analyses at the conclusion of the study provided water content, organic matter content, bulk density, porosity, hydraulic conductivity as well as sampling with depth. The application of a hydroxypropyl-ß-cyclodextrin solution did result in a substantial decrease of the concentrations of DDT, DDE and DDD from the surface soil at Point Pelee National Park. By the end of the experiment, the concentration of DDD was consistently below the regulatory limits set by the Ontario Ministry of Environment and Energy for Parkland/Recreational Land-Use. In addition to the observed decrease in concentration, there was a decrease in the degree of variation between the measured concentrations, transport of the mass of DDT, DDE and DDD to depth and an observed tailing effect at late-times. There were also fundamental changes to the system due to the application of the cyclodextrin (HPCD) solution including an increase in moisture content and organic matter, a decrease in infiltration and a corresponding decrease in field saturated hydraulic conductivity. There was no appreciable benefit of the application of a high concentration solution over a low concentration solution due to an observed "clogging" -effect. The results of this study indicates that further research is necessary to determine the extent of vertical mobilization of DDT, DDE and DDD to groundwater and the role of biological matter in the observed fundamental changes responsible for the "clogging" -effect.</p> / Thesis / Master of Science (MSc)

Folkets Hus. Buildings by the People, For the People. A Story About the Past and the Future.

Karlander, Ellinor January 2021 (has links)
How can I design a modern Folkets Hus with great respectfor the current and historical structures, based on an analysisof existing Folkets Hus buildings?During my project I have kept an open mind towards all the impressions Igathered during my site visits and conversations with knowledgeable people.This has led to changes in my project, as from being about creatinga new Folkets Hus, to reconstructing a Folkets Hus. I have learned that theFolkets Hus history certainly contains an architectural treasure, and in myproject I have tried to bring the existing qualities to the future.

Syster / Sister

Heidenborg, Antonia January 2020 (has links)
Syster är ett kollektivboende och systerbyggnad till en befintlig, kulturminnesmärkt byggnation.   Systerbyggnaden består av två smala parallella volymer, förskjutna så att de i mötet skapar ett större rum. De privata lägenheterna finns i längorna och publika och gemensamma rum i mittenkärnan, som bryggar de två byggnadskropparna. Tre fasadprinciper. Lägenhetsfasadens yttersta lager består av glidande och svängbara träpaneler som skapar ett spel mellan visuell transparens och slutenhet. Gångens glasade fasadväggar växlar och skapar både interiöra och exteriöra rum. Det öppna rummets rumshöga glasfasad i byggnadens mittendel. Ursprungsbyggnadens glasgångar längs parken återkommer i mina korridorer som skapar närhet till naturen och gör att korridorerna tillför något istället för att enbart möjliggöra förflyttning. Skala och vinkel relaterar till ursprungsbyggnaden och i fasadens utformning återkommer dess trädetaljer. Ursprungsbyggnaden är sluten och vänder sig in mot parken, de gemensamma rummen oåtkomliga för andra än boende. Placeringen av entréerna och publika rummen ger i systerbyggnaden uttryck av ökad öppenhet. Förhållandet mellan bostadsdelens repetitiva cell, det publika öppna rummet och cirkulationens betydelse formar systerbyggnaden. De parallella men förskjutna lamellerna ger tydliga gränser mellan det privata och det publika. Den utsträckta byggnadskroppen innebär en många passager. Cirkulationen blir en del av den rumsliga upplevelsen. / Sister is a collective housing and a sister building to an existing, listed cultural monument. The sister building consists of two narrow parallel volumes, with apartments, staggered to create a larger common and public room in the meeting. There are three facade principles. The apartment façade consists of sliding wooden panels that create a play between visual transparency and a closed unit. The glazed facade walls of the corridors alternate and create both interior and exterior spaces. The open room's room-high glass facade in the middle part of the building. The glass corridors of the original building along the park reappear in my corridors, which create closeness to nature and make the corridors add something instead of only enabling movement. Scale and angle relate to the original building and in the façade's design, its wooden details reappear. The original building is perceived as closed while the sister building strives for more openness and the relationship between the residential part's repetitive cell, the public open space and the importance of circulation shapes the sister building. The elongated body of the building involves a lot of passages. The circulation becomes part of the spatial experience.

Mountains on Fire: Making Sense of Change in Waterton Lakes National Park

Buunk, Cassandra Jana 20 August 2021 (has links)
In 2017 the Kenow wildfire burned thirty-eight percent of Waterton Lakes National Park (WLNP) in southern Alberta at high to very high severity in mere hours. The ecological impacts of the fire will have implications for resource management, including the practice of ecological restoration, for decades to come. In this thesis I ask two main questions. First, in what ways are people who are involved in managing WLNP’s ecosystems experiencing the effects of the Kenow wildfire, and how does their experience combined with the severity and extent of the Kenow wildfire influence park management and ecological restoration approaches in WLNP? Subsidiary to this, I ask, what is the role of history, and the role of future climate projections in managing the post-fire landscape? This research is part of the larger Mountain Legacy Project (MLP), which is systematically repeating historic survey photographs taken in the early 1900s across Canada’s mountain landscapes. I use third-view photographs in photo-elicited semi-structured interviews with park staff to answer my first question. In my second research question I ask what broader themes and specific issues do third-view repeat mountain photographs elicit about ecological restoration and park management. As a follow up, I inquire into what ways photo-elicitation functions as an effective method in park management research? Fourteen participants were interviewed, the majority were resource conservation staff, in addition to one retired park warden, a member of the cultural resources unit, a communications staff, and a former staff member. Participants felt wide-ranging emotions relating to the Kenow fire including grief over loss, happiness about regrowth, excitement about learning, anxiety about people’s safety, and stress over increased workloads. Park management frames vegetation regeneration after the Kenow fire as renewal, accepting that the landscape may look different than it did before the fire. Climate change is only beginning to be integrated into ecological restoration, though park management is adapting to climate change by encouraging renewal under a new climate. Historical knowledge still guides decision making in several ways. Major restoration projects including invasive species management, whitebark and limber pine restoration, and prescribed burning, were all impacted by the Kenow fire. Participants shared their thoughts on unconventional approaches such as novel ecosystems, highlighting misunderstandings and misapprehensions about the concept. Parks Canada has an opportunity to learn from Waterton Lakes’ experience to help streamline their post-emergency response in the future. Findings relating to my second question show these themes and issues were discussed most often by participants when looking at the third-view mountain photographs: fire behaviour, regeneration/renewal, and ecological impacts of the Kenow fire; encroachment; prescribed burning; personal narratives; ecological effects of climate change; and other snapshots. Just less than half the participants did not engage significantly with the photos, which highlights a challenge in using researcher chosen photos. However, many participants did engage and had much to say about the photos, including sharing memories and personal stories. Pre-determined interview questions were essential in unearthing the findings in this thesis, as the photos did not elicit this information alone. / Graduate

Enviromentální vědeckotechnický park v Zábřehu / Enviromental Science & Technology Park in Zábřeh

Kratochvílová, Šárka January 2009 (has links)
Diploma project develops the intention to build up an ecological project based on renewable resources utilization of energy and materials recycling in Zábřeh. The study is engaged in possible area extension and tries to divide it into functional zones, when zone of main production remains the same (already elaborated project) and the zone of extension where there is settled production storages, alt.production hall extension. Third zone, so-called green zone, is developed in more detail. The green zone is a belt of plot separating the production area from second-class road nr.315, and also creates entrance gateway and lungz of the whole area. The green belt is conceived as a sojourn park with water elements(biotopes, lake, water basin), which is intersected by wooden footbridge, that connects object of multifunction pavilion and office building and ends at articifial island, or more precisely as a torso in the lake waters, symbolizing the science, which´s end is far away for human beings. The footbridge is also an axis between planned science-technological centres for the direct processing of waste materials. Administration building and pavilion are conceived as a „second nature“, purely human artifact, whih is also clearly expressed in „non-natural“ materials used. Their concept tries to saturate client´s requests and use the renewable resources of energy with observance of building biology principles (author´s request) at the same time.
