Estudo do impacto da construção de duas barragens na dinâmica populacional de mosquitos (Diptera: Culicidae) na região metropolitana de São Paulo / Study the impact of dam construction in two population dynamics of mosquitoes (Diptera: Culicidae) in the Region São Paulo Metropolitan

D\'Avila, Frederico Alves 22 August 2011 (has links)
Assim como qualquer empreendimento que altera localmente o regime de águas, a construção de barragens de abastecimento modifica a ecologia dos culicídeos, podendo levar ao aparecimento de surtos. Foi comparado como foi a resposta dessa comunidade na construção das barragens de Biritiba-Mirim e Paraitinga, entre 2002 e 2005. Ambas fazem parte do Sistema Produtor do Alto Tietê, responsável pelo abastecimento da maior parte da região metropolitana de São Paulo. A amostragem aconteceu pelo método de Armadilha de Shannon, a partir dos dados coletados foram calculados índices dos componentes ecológicos, como riqueza, constância, abundância, similaridade e outros. A análise destes componentes revelou que a fauna de mosquitos das duas barragens possuíam estágios iniciais diferentes, logo tiveram reações diferentes ao impacto. Em Biritiba-Mirim estava presente uma fauna silvícola, que diminuiu grandemente com a inundação, enquanto a fauna associada a macrófitas e a criadouros temporários cresceram, isso levou a diminuição da diversidade no período estudado. Em Paraitinga a fauna silvícola era reduzida, então as modificações, qualitativa e quantitativas foram pequenas. Foram encontradas as seguinte espécie de importância médica: Mansonia titillans, Anopheles galvaoi, Anopheles albitarsis s.l., Anopheles evansae, Anopheles intermedius, Anopheles cruzii, Anopheles lutzi, Anopheles triannulatus, Aedes albopictus, Aedeomyia squamipennis, Psorophora ferox, Culex (Melanoconion) sp., Culex amazonensis, Limatus durhami, Aedes scapularis e Aedes serratus / Like any enterprise that locally modify the water regime, the construction of dams supply modifies the ecology of Culicidae, which may lead to the emergence of epidemic outbreaks. In the present study was studied and compared as was the response of this community in the construction of dams and Paratirinda Bitiriba- Mirim, between 2002 and 2005. Both are part of the Alto Tiete System Producer, responsible for supplying most of metropolitan Sao Paulo. Sampling took place at Shannon trapping method, based on data collected were calculated index of ecological components, such as wealth, constancy, abundance, similarity, and others.The analysis of these components revealed that the faunas of the two dams had different stages, soon had the impact difererentes reactions. In Biritiba Mirim was present a wildlife forestry, which greatly diminished with the flood, while the fauna associated with macrophytes and temporary breeding sites grew, this led to decreased diversity in the period studied. In forestry Paraitinga fauna was absent, so the modifications were minor qualitative and quantitative. We have found the following species of medical importance: Mansonia titillans, Anopheles galvaoi, Anopheles albitarsis s.l., Anopheles evansae, Anopheles intermedius, Anopheles cruzii, Anopheles lutzi, Anopheles triannulatus, Aedes albopictus, Aedeomyia squamipennis, Psorophora ferox, Culex (Melanoconion) sp., Culex amazonensis, Limatus durhami, Aedes scapularis, Aedes serratus.

A CINEMATIC VILLAGE FOR A CHANGING LANDSCAPE - AN ALPINE ROMANTIC STORY

Sacco, Diana January 2022 (has links)
Climate change has already had noticeable effects on the environment. Glaciers are retreating, ice on lakes and rivers is melting earlier, plant and animal species have relocated, and trees are blooming sooner. The Alpine landscape is one very good example of these dramatic shifts, which significantly impacted its identity and the economic stability of its communities. The effects on the classic forms of alpine tourism, especially the winter one, coupled with the mismanagement of the land and the lack of valorisation of the cultural heritage of the valleys have led to two equally disruptive phenomena: on one side, mass overtourism affects the most popular locations in the mountains requiring the construction of new infrastructures and resorts; on the other, the abandonment of the smallest or less known villages threatens the disappearing of rural communities with the consequent undermining of their surrounding landscape. Addressing the recovery plan drafted by the Italian Government after the pandemic (PNRR 2021), which includes giving new life to smaller villages and their ecological environment as well as reintroducing the Italian cinematographic industry as a competitive player within the international scene, the project aims to tackle the progress/paradox situation affecting the Italian Alps, Overtourism versus Abandonment, and its consequent impact on the landscape. The design is located in the Valle D’Aosta region, due to its proximity to Turin, a scenographic city where Italian cinema was born, and to its controversial nature which sees overbooked glamorous locations juxtaposed to the abandoned small rural realities. Particularly the proposal takes the story of the hamlet of Oyace, whose abandoned buildings are currently being sold at the symbolic price of 1 euro, in order to imagine a different future for alpine communities, which includes both economic growth and environmental awareness.Thought as a continuous dialogue between reality and fiction, the project starts in Oyace, taking shape as a film director’s studio in one of the currently abandoned buildings. It then continues as a new village envisioned by the director on the nearby artificial lake de Place Moulin, chosen for its symbiotic natural and man-made environment. The masterplan, drafted as a movie unfolding on site, borrows from the narrative of a romantic novel, Hypnerotomachia Poliphili, written by Italian Francesco Colonna and published in Venice in 1499, which is set in mythical and personified landscapes. The different chapters of the novel with their allegorical nature inspire the ethos of each of the buildings of the village.The architecture of the proposal, which accommodates different programs typically present in a traditional Italian alpine village alongside spaces and structures necessary to the moviemaking, borrows from alpine forms and heritage, set design and movie strategies and the landscape. The result is a series of performative infrastructures staging, re-enacting, revealing and counteracting issues currently experienced by the hamlet of Oyace, these can be environmental, social or economic, and their consequences on the alpine environment. Despite taking from the story of the book and manifesting itself as a village, the project is not limited to the novel, but rather it attempts to start an investigation into the role of architecture within the wider context of the endangered alpine environment, whilst arguing for a multidisciplinary approach and the use of narrative as critical tools for the production of impactful architecture in times of crisis.Ultimately the design aims to envision a new future for the community of Oyace and its ecological environment, speculating on a new approach towards giving new life to alpine communities based on a deeper awareness of their surrounding environment.

Revitalizace hotelového zařízení, Přehrada Brno / Revitalisation of the Hotel Facility by the Brno Artificial Lake

Švec, Martin Unknown Date (has links)
This is the proposal of the new utilization of the former recreational centre, which is situated in the beautiful surrounding of the Brno lake. It has been abandoned for many years and is suffering from decay. It has been built in the 1970's for the demand of the Socialistic youth union (remark: the youth organisation of the communist's party). There were held international political conventions and educational sojourns for the students of high schools and universities. The new utilization will be analogous. Only the communist's ideals will be replaced with the ideals of today's democratical society – especially friendly relations between mankind and environment. There will be created the environmental educational centre with the meeting spaces, conference hall and accomodation. The universal concept enables the usage of the facility also for the international students' workshops, training courses, teambuilding events etc. The ecological educational centre primarily makes the good example and is the live educational requisite. Thanks to the concept of the original facility is very convenient the refurbishment to the standard of the energetically passive building, which consists from the natural materials and utilizes renewable energy resources. Because of the very poor technical condition and devastation of the building will be re-used only basement and steel framework. This solution is more economical than the demolition and following new construction. The construction core of the building is almost for free. However, only if we make minimal changes in the framework and we preserve the original building's shape. On the steel framework will be created the new lightweight housing, which will be made from wood, straw pannels and filled with the cannabis thermal insulation. Almost all the roofs will be covered with the photovoltaic foils and the heat source will be air heat pump. The area is very pleasant place to stay. It's full of sunshine all day long and offers very beautiful view of the lake. The main building and bungalows profit of the attractive views. All the former recreational area has was designed to make the people meeting together and to provide the freedom of move and wide variety of activities. However, the rooms and bungalows provide the highest privacy. The inside and outside of the buildings are shading into each other. All the recreational ground – in exterior and interior – is full of liveliness, in the opposite of the rooms, which are the private islands. This aspect, which is present in the former concept from the 1970's, is to be preserved. The former hotel building is distinguished by the quality architectural concept, above-average in the age of origin. It is thanks to the dynamically balanced composition – inspirative today too, and visually interesting interior design of the meeting spaces. This proposal attempts to continue in this qualities. The ground is enriched with the relaxational spaces and the outside gym path. In the opposite of the original state the area is open to the public and is utilized as a park for leisure activities.
