Earthquake-Induced Ground Fissuring in Foot-Slope Positions of the Port Hills, ChristchurchStephen-Brownie, Charlotte Jane January 2012 (has links)
Following the 22 February 2011, MW 6.2 earthquake located on a fault beneath the Port Hills of Christchurch, fissuring of up to several hundred metres in length was observed in the loess and loess-colluvium of foot-slope positions in north-facing valleys of the Port Hills. The fissuring was observed in all major valleys, occurred at similar low altitudes, showing a contour-parallel orientation and often accompanied by both lateral compression/extension features and spring formation in the valley floor below. Fissuring locations studied in depth included Bowenvale Valley, Hillsborough Valley, Huntlywood Terrace–Lucas Lane, Bridle Path Road, and Maffeys Road–La Costa Lane.
Investigations into loess soil, its properties and mannerisms, as well as international examples of its failure were undertaken, including study of the Loess Plateau of China, the Teton Dam, and palaeo-fissuring on Banks Peninsula. These investigations lead to the conclusion that loess has the propensity to fail, often due to the infiltration of water, the presence of which can lead to its instantaneous disaggregation. Literature study and laboratory analysis of Port Hills loess concluded that is has the ability to be stable in steep, sub-vertical escarpments, and often has a sub-vertically jointed internal structure and has a peak shear strength when dry.
Values for cohesion, c (kPa) and the internal friction angle, ϕ (degrees) of Port Hills loess were established. The c values for the 40 Rapaki Road, 3 Glenview Terrace loess samples were 13.4 kPa and 19.7 kPa, respectively. The corresponding ϕ values were thought unusually high, at 42.0° and 43.4°.The analysed loess behaved very plastically, with little or no peak strength visible in the plots as the test went almost directly to residual strength.
A geophysics resistivity survey showed an area of low resistivity which likely corresponds to a zone of saturated clayey loess/loess colluvium, indicating a high water table in the area. This is consistent with the appearances of local springs which are located towards the northern end of each distinct section of fissure trace and chemical analysis shows that they are sourced from the Port Hills volcanics.
Port Hills fissuring may be sub-divided into three categories, Category A, Category B, and Category C, each characterised by distinctive features of the fissures. Category A includes fissures which display evidence of, spring formation, tunnel-gullying, and lateral spreading-like behaviour or quasi-toppling. These fissures are several metres down-slope of the loess-bedrock interface, and are in valleys containing a loess-colluvium fill. Category B fissures are in wider valleys than those in Category A, and the valleys contain estuarine silty sediments which liquefied during the earthquake. Category C fissures occurred at higher elevations than the fissures in the preceding categories, being almost coincident with bedrock outcropping.
It is believed that the mechanism responsible for causing the fissuring is a complex combination of three mechanisms: the trampoline effect, bedrock fracturing, and lateral spreading. These three mechanisms can be applied in varying degrees to each of the fissuring sites in categories A, B, and C, in order to provide explanation for the observations made at each. Toppling failure can describe the soil movement as a consequence of the a three causative mechanisms, and provides insight into the movement of the loess. Intra-loess water coursing and tunnel gullying is thought to have encouraged and exacerbated the fissuring, while not being the driving force per se. Incipient landsliding is considered to be the least likely of the possible fissuring interpretations.

Documentary Photography as a Tool of Social Change: reading a shifting paradigm in the representation of HIV/AIDS in Gideon Mendel's photographyNesbitt Hills, Christine January 2011 (has links)
Gideon Mendel’s ongoing photographic work documenting HIV/ AIDS, first started in 1993, has seen shifts not only in production but also in the author’s representation of his subjects. This paper looks at three texts of Mendel’s work, taken from three different stages of Mendel’s career and reads the shifting paradigm taking Mendel from photojournalist to activist armed with documentary photography as a tool of social change. This thesis explores how different positionings as an author and different representations of the subjects, living and dying, with HIV/AIDS influences meaning-making, and what that means for documentary photography as a tool of social change.

MORAVSKÉ VINAŘSKÉ CENTRUM BRNO / Moravian wine centre BrnoPeková, Pavla January 2016 (has links)
This diploma thesis gives a proposal for a new Moravian wine center in the city center of Brno. Wine center is situated on the street Hlinka, where grapevines were planted in the Middle Ages. Demarcated land is narrow and elongated sloping towards to the south and connects the Yellow hills and the Brno Exhibition Centre. The main idea of this thesis is connect these two significant locations and offer the visitor a free passage along the entire length of the complex. Also main building Moravian Wine Centre reflects this fact and it expands the space of the street stalls and forms it into overgrown "arcade". The house is opened into this space - with glazed facade of the first two floors or with transmission into the rear wing. The main building consist of the cellar, where it is located wellness, winehouse, rentable wine boxes and tasting room connected with wine production. The rest of floors are designed for wine gallery, information center, reception, shop, restaurant, conference center and hotel. There is a café with roof terrace in the last floor. It offers a magnificent view into cityscape of Brno, Brno Exhibition Centre and the Yellow slope of the hill. There is designed a pond for relaxation in the courtyard. Nearby is situated Wine Institute building with facilities for making wine. In the second half of the land are located three blocks of luxury apartments in the middle of a vineyard. A leading construction is the most striking feature of the facade that reminds bougainvillea vines with vaulted arches wine cellars and attracts at first sight.

Kulturně společenské centrum u brněnské přehrady - architektonická studie objektů pro kulturně společenské i sportovní akce / The cultural and community centre near the Brno dam - the architectural design of buildings for cultural and social and sports eventsŠmihula, Michal January 2010 (has links)
The design of cultural centre is situated in part Kozia Hôrka( well-known city swimming pool), in its advantage takes natural scenery and calm atmosphere of place. Into action of performance brings a message in form of body of reservoir, function of centre is divided into small parts placed in area Kozia Hôrka. Orientation of objects comes mainly from local natural ispirations. Complex is multifunctional in concept, counts with several sorts of culture - sports events. Whereby the main function of swimming pool is preserved and added for higher comfort of inhabitants. Architecture of objects comes from idea of floating leaf on water level and body of reservoir. Objects stylizely illustrate this idea. The design takes the game of solids of organic and strictly ortogonal shapes. Two mutual opposites, in interaction. Objects smoothy and with respect encroach the environment, which is enough marked by human. Simplicity in used materials ( glass, steel, wood ) give transparency and purity to whole solution.
