Full textCurrent research about wildlife has tended to emphasize the contributions of scientific perspectives. This thesis argues that the practice of wildlife rehabilitation (WR) also offers significant information to academic discourse. The goals of my study were to explore and describe the different perspectives and knowledges generated about wildlife through the practice of wildlife rehabilitation and the rehabilitators' relationships with their wild animal patients, through the use of qualitative methods including semi-structured interviews and autoethnography. I interviewed seven WR professionals about their nonhuman animal patients, education animals, and human staff and volunteers. The autoethnographic information used in this study was gathered from my own experience as a wildlife rehabilitator.
Five key themes emerged from my research. 1) The altruistic roles taken on by wildlife rehabilitators (both caregiving and training roles) improve communication with other animal individuals. 2) The subjective experience plays critical roles, both positive and negative, in the practice of wildlife rehabilitation and the ability to understand wildlife. 3) The sense of obligation and responsibility to address anthropogenic injuries to other animals leads humans to become wildlife rehabilitators. 4) Wildlife experience with, and education about, other animal species are important factors in forming an appreciation for wildlife. 5) The practice of wildlife rehabilitation generates significant information about wildlife and medicine that is useful to discourse about wildlife.
This study will be relevant to professionals from other fields that work with wildlife and nonhuman animals: conservation, wildlife management, animal communication, and to the new field of trans-species psychology, among others. Captive environments and enrichment for education animals at WR centers could be used as models for captive animals in other industries: entertainment (zoos and circuses), as well as laboratory and research institutions. Finally, this theoretical analysis of WR, placed in the context of power relations, offers a significant contribution to human-centered studies such as those of human ethics (biomedical, especially, and around human test subjects), medicine and public health, and studies of social justice.

Full textAnglo American Corporation’s Namakwa Sands heavy minerals mining and beneficiation operation has been strip-mining a heavy mineral deposit, rich in the commercially valuable minerals ilmenite, rutile and zircon, since September 1994. The mine is located in the vicinity of Brand-se-Baai on the west coast of South Africa, approximately 385 km north of Cape Town. Strip-mining causes total destruction of natural ecosystems through the removal of vegetation and soil in the area where mining is being undertaken. Namakwa Sands has been rehabilitating mined out areas as the mining front moves forward. Due to the difficulty of rehabilitating mined out areas as a result of harsh environmental factors, Namakwa Sands has initiated various research projects to gain an understanding of the baseline conditions and ecosystem function in order to increase plant cover and biodiversity on post-mined areas. This on-going research and the development of rehabilitation and mining techniques have resulted in the implementation of four rehabilitation techniques varying in investment of topsoil replacement, seeding and plant translocation. This study assesses the success and effectiveness of these techniques in terms of various vegetation and soil parameters. In addition, those parameters that are considered useful for monitoring are identified. This study indicated that topsoil replacement and plant translocation facilitate the return of similarity, species richness, species diversity and vegetation cover to post-mined areas. The rehabilitation site that had the greatest amount of biological input (topsoil replacement and plant translocation) appeared to be the most successful technique in facilitating vegetation recovery similar to reference sites. In comparison, the site that had the least amount of biological input performed the worst and requires adaptive management, e.g. reseeding and / or plant translocation. Namakwa Sands should continue to replace topsoil in all future rehabilitation efforts and, when possible (e.g. after sufficient winter rain), continue to translocate species in multi-species clumps. In terms of species selected for translocation, Othonna cylindrica, Ruschia versicolor and Lampranthus suavissimus should be considered for future large-scale translocation projects. Zygophyllum morgsana appears to be more difficult to re-establish under the current climatic conditions (below average rainfall). The long-term viability of rehabilitated Z. morgsana populations needs to be determined before considering this species for any future large-scale translocation purposes. No translocated Asparagus spp. individuals survived and should therefore not be considered for any further translocation purposes. The grass Ehrharta calycina, which is dominant in the site seeded, should continue to be considered for future seeding. Species and functional diversity appear to be the most limiting factors within all the rehabilitation sites and Namakwa Sands will not be able to meet their long-term objective of small-stock farming if diversity and the number of palatable species do not increase significantly. Adaptive management should seriously be considered in order to speed up this process. Alternatively, an appropriate grazing strategy, which is related to the Tetragonia fruticosa dominated vegetation within rehabilitation sites, would need to be determined and adopted.More time is needed to ameliorate the rehabilitated soil profiles to the same level as in reference sites, especially with regard to carbon, pH and sodium levels. In order to increase organic matter within rehabilitation areas, Namakwa Sands should consider creating clumps with cleared vegetation from the mining front. Since the long-term rehabilitation goal has not been achieved, Namakwa Sands will need to continue to monitor plant and soil changes until it has been achieved. The objectives of the current rehabilitation programme are limited and Namakwa Sands should develop additional objectives relating to the structure and function of the natural vegetation. This will give a better indication of whether rehabilitation sites are progressing towards the desired end point and if adaptive management is required. In addition, the current monitoring programme (vegetation survey) implemented at Namakwa Sands could be improved by increasing the vegetation parameters to be monitored. It is recommended that the following vegetation parameters be monitored as part of the long-term monitoring programme: species composition and similarity, species richness, species diversity, vegetation cover, species dominance, vertical structure and functional diversity of the vegetation (clumps and inter-clumps). It is also recommended that carbon, pH and sodium of soil profiles be monitored as part of the long-term monitoring programme. These parameters should not be seen as exhaustive as this study only considered various vegetation parameters and soil chemistry between rehabilitation and reference sites. The results of other studies on the fauna, mycorrhiza, insects, etc. should also be taken into consideration and the monitoring parameters expanded accordingly.

Full textIn an effort to confront global warming and the increasing scarcity of resources, the preservation community began several years ago to adopt sustainable and green building practices and metrics for historic rehabilitation projects. As a result, there is an ever growing number of rehabilitated historic buildings in the United States not only incorporating sustainable building designs but also achieving Leadership in Energy and Environmental Design (LEED) certification. Most of these are large, architect-designed buildings in urban settings rehabilitated for cultural and commercial uses. This thesis explores the application of the LEED 2009 New Construction and Major Renovation Rating System for the development of a sustainable rehabilitation plan for the modest vernacular 1897 Jeff. Smith's Parlor Museum in Skagway, Alaska. The goal of this research is to demonstrate how the LEED rating system might be applied to the rehabilitation of this building and other historic vernacular buildings.

Full textENGLISH ABSTRACT: The Exxaro Namakwa Sands heavy mineral sands mine at Brand-se-Baai, on the west coast of South Africa, is an important source of income, development and job-creation in the region. However, this comes at a great environmental cost, as strip mining causes large scale destruction of ecosystems through the complete removal of vegetation and topsoil. This is particularly problematic in an environment, such as Namaqualand, where the arid and windy climate, as well as saline and nutrient-poor soils, hamper rehabilitation. These environmental constraints create the need to develop a site-specific rehabilitation program. At Namakwa Sands the objective of rehabilitation is to “rehabilitate and re-vegetate disturbed areas and establish a self-sustaining Strandveld vegetation cover in order to control dust generation, control wind and water erosion, as well as restore land capability. In general, vegetation will be rehabilitated to a minimum grazing standard capable of supporting small stock (sheep) grazing.” In order to achieve this Namakwa Sands conducted rehabilitation experiments with topsoil replacement, seeding of indigenous species and translocation of mature plants. Monitoring is an important part of the rehabilitation process as it allows rehabilitation practitioners to evaluate success and to adapt their management strategies and rehabilitation methods, as well as to evaluate and, if necessary, change their rehabilitation objectives. This study forms part of the monitoring process at Namakwa Sands. It assesses the success of sites that were experimentally rehabilitated in 2001 and a site that was rehabilitated in 2008, using current practice, in order to identify possible management requirements on rehabilitated sites as well as improvements on rehabilitation objectives, methods and monitoring. This study also tests the Landscape Function Analysis (LFA) as rehabilitation monitoring tool by correlating LFA indices with traditional measurements of biophysical variables or their surrogates. Results showed that experimental sites were not successful in returning vegetation cover and plant species richness to the required levels, but did achieve the grazing capacity objective. These sites will need adaptive management to achieve the vegetation cover and plant species richness objectives. The recently rehabilitated site achieved the three-year vegetation cover and plant species richness objectives, as well as the grazing capacity objective, within two years after rehabilitation. Namakwa Sands should therefore continue using the current rehabilitation method. However, rehabilitation should be done in multiple stages in future to decrease the mortality of nursery cuttings and to facilitate the return of late successional species to rehabilitated sites. The sustainability of small stock farming on rangeland with the grazing capacity that is identified as the minimum objective is questionable and this merits further investigation. LFA can be a useful tool to monitor nutrient cycling and soil stability at Namakwa Sands, provided that enough replicates are used. However, LFA cannot be used as is to assess water infiltration at Namakwa Sands, due to assumptions in the calculation of this index that do not hold for the Namaqualand environment. Landscape functioning should be monitored annually to complement vegetation surveys.
AFRIKAANSE OPSOMMING: Die Exxaro Namakwa Sands swaarminerale-sandmyn by Brand-se-Baai, aan die weskus van Suid-Afrika, is ‘n belangrike bron van inkomste, ontwikkeling en werkskepping in die streek. Daar is egter negatiewe omgewingsimpakte aan verbonde, aangesien die strookmyntegniek grootskaalse vernietiging van ekosisteme veroorsaak deur die algehele verwydering van die plantegroei en bogrond. Dit is veral problematies in ‘n omgewing, soos Namakwaland, waar die droë en winderige klimaat, asook die souterige en voedingstof-arme grond, rehabilitasie belemmer. Hierdie beperkings wat deur die omgewing veroorsaak word skep die behoefte om ‘n rehabilitasieprogram te ontwikkel wat spesifiek is tot die terrein. Die doel van rehabilitasie by Namakwa Sands is om te rehabiliteer en herplant op versteurde gebiede en om selfonderhoudende Strandveld plantbedekking te vestig om sodoende stofgenerering te beheer, om wind- en watererosie te beheer, en om grondgebruik-vermoë te herstel. In die algemeen sal plantbedekking gerehabiliteer word tot ‘n minimum weidingskapasiteit wat kleinveeweiding (skaapweiding) kan onderhou. Om dit te bereik het Namakwa Sands rehabilitasie-eksperimente uitgevoer met terugplasing van bogrond, saai van inheemse spesies en oorplanting van volwasse inheemse plante. Monitering is ‘n belangrike deel van die rehabilitasieproses, aangesien dit rehabilitasie-praktisyns in staat stel om sukses te evalueer en om bestuurstrategieë en rehabilitasiemetodes aan te pas, sowel as om rehabilitasiedoelwitte te evalueer en, indien nodig, aan te pas. Hierdie studie vorm deel van die moniteringsproses by Namakwa Sands. Dit assesseer die sukses op persele wat eksperimenteel gerehabiliteer is in 2001 en ‘n perseel wat in 2008 gerehabiliteer is, volgens die huidige praktyk, om moontlike bestuursbehoeftes op gerehabiliteerde persele en verbeteringe aan rehabilitasiedoelwitte, -metodes en –monitering te identifiseer. Hierdie studie toets ook die geskiktheid van die Landscape Function Analysis (LFA) as ‘n rehabilitasie-moniteringsinstrument deur LFA-indekse met tradisionele metings van biofisiese veranderlikes of hul surrogate te korreleer. Resultate dui daarop dat eksperimentele persele nie suksesvol was om plantbedekking en plantspesies-rykdom tot die vereiste vlakke te herstel nie, maar wel die weidingskapasiteit-doelwit bereik het. Hierdie persele benodig aanpassingsbestuur om plantbedekking- en plantspesiesrykdom-doelwitte te bereik. Die perseel wat onlangs gerehabiliteer is, het binne twee jaar na rehabilitasie die drie-jaar plantbedekking- en plantspesiesrykdom-doelwitte, sowel as die weidingskapasiteitdoelwit bereik. Daarom moet Namakwa Sands voortgaan om die huidige rehabilitasiemetode te gebruik. Rehabilitasie moet egter in die toekoms in veelvoudige stadiums gedoen word om die mortaliteit van kwekery-steggies te verminder en om die terugkeer van laatsuksessionele spesies na gerehabiliteerde persele te fasiliteer. Die volhoubaarheid van kleinveeboerdery op weiveld met die minimum vereiste weidingskapasiteit word betwyfel en vereis verdere ondersoek. LFA kan ‘n bruikbare instrument wees om siklering van voedingstowwe en grondstabiliteit te monitor by Namakwa Sands indien genoeg repliserings gebruik word. LFA kan egter nie in die huidige vorm gebruik word om waterinfiltrasie by Namakwa Sands te assesseer nie, aangesien daar aannames in die berekening van die indeks is wat nie juis is in die Namakwaland omgewing nie. Landskapfunksionering behoort jaarliks gemoniteer te word om plantopnames aan te vul.

Full textDespite no penguin breeding colonies along the Brazilian coast, the country is an important wintering area for the Magellanic penguin (Spheniscus magellanicus), a species native to the south of South America. When Magellanic penguins are found alive ashore on Brazilian beaches, they are taken to rehabilitation centers to receive veterinary care and then are released back into the wild. However, while in rehabilitation, infectious diseases such as avian malaria may become important limiting factors for the recovery of these birds. Avian malaria is a disease caused by protozoa of the genus Plasmodium (Apicomplexa: Haemosporida), which are transmitted to birds through mosquitoes. While these parasites are relatively non-pathogenic for most avian species, some birds such as penguins are exceptionally susceptible, such that Plasmodium poses a significant conservation threat. This study investigates the occurrence of Plasmodium spp. and other blood parasites in Magellanic penguins at rehabilitation centers along the coast of Brazil, and in other species of penguins at the South Shetland Islands, South Atlantic Ocean. In Brazil, a combination of morphological (blood smears, histopathology) and molecular (nested polymerase chain reaction, gene sequencing) diagnostic methods were employed to investigate the presence of haemoparasites in penguins undergoing rehabilitation in six states between 1999 and 2013. A particularly significant avian malaria outbreak was studied in detail at a rehabilitation center in Florianópolis, SC, where the involvement of three distinct Plasmodium spp. in a single epizootic event was demonstrated, with resultant high morbidity and mortality. The occurrence of Plasmodium spp. was documented in Magellanic penguins at rehabilitation centers along most of the Brazilian coast, from southernmost Rio Grande do Sul to Bahia, with an estimated prevalence between 6.6% and 13.5% of captive penguins. These infections were markedly seasonal, with the incidences exclusively restricted to the warmer months of the year (October to April), and involving a broad variety of Plasmodium spp. lineages, some of which had not yet been reported in penguins, such as P. cathemerium, P. nucleophilum and P. tejerai. In contrast, no blood parasites were detected in the penguins sampled at the South Shetland Islands, a finding that is consistent with previous studies. Aside from these epidemiological investigations, an extensive revision and compilation of the scientific literature was conducted for this disease and other penguins haemosporidioses, aiming to establish an integrated understanding of their geographic distribution and epidemiological and conservation implications. On this basis, it is possible to critically examine the state of the art and identify knowledge gaps that can be addressed in future studies. Avian malaria is a significant disease and conservation threat for most penguin species throughout the world, and has particular importance for the rehabilitation and conservation of penguins in South America.

Este trabalho final de mestrado, em particular, detém- -se sobre um palácio do fim do século XIX e o sobre o respetivo perímetro envolvente, localizado no concelho de Loulé. O lugar, nomeado originalmente pelo proprietário como Quinta da Esperança, mas que subsiste até hoje nomeado como Quinta da Fonte da Pipa, encontra-se votado a um abandono que é alvo de muitas críticas, reclamando- -se à escala local uma intervenção urgente, no sentido da sua preservação. Para além do trabalho de análise e interpretação que procura garantir a valorização correta da pré-existência, faz-se ainda objeto do trabalho a realização de uma proposta para a reabilitação funcional do Palácio, por forma a suportar visitas pontuais, a realização de atividades culturais diversificadas e ainda – com o apoio logístico de uma segunda infraestrutura a reabilitar a sul do palácio – a possibilidade eventual de pernoitar na antiga propriedade.
ABSTRACT: Rehabilitation, conservation and restoration are concepts that need to be revisited for each intervention, covering them to explore the history of the object in question. The final masters work project, in particular, is a place with a palace of the late 19th century in the County of Loulé. The first owner called the place Quinta da Esperança, but it’s now called Quinta da Fonte da Pipa. At the moment, it’s in a state of abandonment, making it a target of criticism, meaning, today it needs an urgent intervention. In addition to the work of analysis and interpretation to guarantee the correct appreciation of its pre-existence, there will be a proposition for a functional rehabilitation and creation of regional activities for its visitants. To support this proposition, a building south of the palace will be created, so visitors can stay overnight.

ENGLISH ABSTRACT: The main aim of an old field rehabilitation trial initiated in 2000 was to find a solution to the rehabilitation process for approximately 90 000 ha of unutilised land in the Little Karoo, South Africa. Depending only on a natural succession process to restore unutilised old fields would mean that the period of recovery would be longer than the life span of an average farmer. The trial, initiated by Witbooi in 2000 aimed to see how human intervention can facilitate the process of rehabilitation of old-fields. Three years later, the trial was again monitored to evaluate the success of reseeded indigenous species and method of cultivation in the rehabilitation process. A second objective was based on a result of Witbooi (2002) who showed that there was a tendency of 0. pes-caprae to invade disturbed areas, and aimed to evaluate the effect of this species on the rehabilitation process. Seven indigenous species were reseeded in 2000, of which only four species germinated and survived to the present. These surviving species are Pteronia incana Burm Dc., Tripteris sinuata DC., Ehrharta calycina SM and Chaetobromus dregeanus Nees. The highest level of recruitment in 2001 was recorded for T sinuata followed by P. incana, E. calycina and C. dregeanus. In September 2003, three years after the trial was initiated, the highest number of surviving seedlings were of T sinuata followed by E. calycina, C. dregeanus and P. incana. Five different cultivation methods were used to enhance the germination rate and survival of seedlings. The number of seedlings that survived differs according to the cultivation methods and soil type. Tripteris sinuata had the highest number of surviving seedlings in all cultivation methods off-heuweltjies. Tripteris sinuata was therefore selected to analyse the effect of various cultivation methods. The second objective was to study the impact of Oxalis pes-caprae on species diversity in restored old fields by assessing its ability to disperse in old fields under different cultivation methods. The multivariate ANOVA results showed that there was a significant difference in the density of O. pes-caprae between on and off heuweltjies (sites) and treatments (cultivation methods). There was a significant difference in the density of O. pes-caprae between cultivation methods. A Post Hoc LSD test showed a significant difference in the density of aboveground O. pes-caprae plants between control sites (no disturbance) compared to those sites that underwent some sort of soil disturbance. There was, however, no significant difference in the abundance of O. pes-caprae on plots that underwent some sort of disturbance (i.e Cleared vs Tilled vs Disked vs Ploughed sites) on heuweltjies. There was a significant difference in the number of O. pes-caprae bulbs collected between blocks (on and off-heuweltjie) and significant differences between cultivation methods. There was also a significant difference in bulb diameter between cultivation methods when compared between on and off-heuweltjie sites. The bulbs were classified into four measurement classes. The highest number of small (2-5 mm diameter) and medium (5-8 mm diameter) sized bulbs were found in the Tilled cultivation method. In contrast the Control treatment (uncultivated) had the highest number of large sized bulbs (14-17 mm diameter) and medium bulbs size categories. In conclusion, T. sinuafa has the potential to be used for rehabilitation of old fields in combination with Tilled cultivation method. Attention should be paid to the effect of O. pes-caprae especially on heuweltjies where this species showed a complete dominance in the rehabilitation trial.
AFRIKAANSE OPSOMMING: Die hoof doel van 'n ou veld rehabilitasie eksperiment wat in 2000 geinisieer is was om 'n oplossing te vind vir die rehabilitasie proses vir ongeveer 90 000 ha onbenutte land in die Klein Karoo, Suid-Afrika. Indien daar slegs op natuurlike suksessie prosesse staatgemaak word om die onbenutte ou lande te restoreer, sou dit beteken dat die periode van herstel langer sou wees as die lewensverwagting van die gemiddelde boer. Hierdie eksperiment, wat in 2000 deur Witbooi geinisieer is, het gepoog om te bepaal hoe menslike inmenging die proses van rehabilitasie van ou velde kan fasiliteer. Drie jaar later is die eksperiment weer gemonitor om die sukses van die teruggesaaide inheemse spesies en bewerkings-metodes in die rehabilitasie proses te evalueer. 'n Tweede doelwit is gebaseer op 'n resultaat van Witbooi (2002) wat aangetoon het dat daar 'n neiging was vir O. pes-caprae om versteurde areas binne te dring, en het dus gemik om die effek van hierdie spesie op die rehabilitasie proses te evalueer. Sewe inheemse spesies is in 2000 teruggesaai, waarvan slegs 4 spesies ontkiem en oorleef het tot die hede. Hierdie oorlewende spesies is Pteronia incana Burm Dc., Tripteris sinuata DC., Ehrharta calycina SM en Chaetobromus dregeanus Nees. Die hoogste vlak van werwing in 2001 is vir T sinuata aangeteken, gevolg deur P. incana, E. calycina en C. dregeanus. In September 2003, drie jaar na die aanvang van die eksperiment, was die hoogste getal oorlewende saailinge die van T sinuata, gevolg deur E. calycina, C. dregeanus en P. incana. Vyf verskillende bewerkings-metodes is gebruik om ontkiemingstempo en saailing oorlewing aan te help. Die aantal saailinge wat oorleef het varieer volgens die bewerkings-metode wat gevolge is en die grondtipe. Tripteris sinuata het die grootste aantal oorlewende saailinge gehad in al die bewerkings-metodes af van heuweltjies. Tripteris sinuata is daarom geselekteer om te analiseer vir die effek van verskillende bewerkings-metodes. Die tweede doelwit was om die inpak van Oxalis pes-caprae op spesie-diversiteit in die gerestoreerde ou land te bepaal deur die vermoë van hierdie spesie om in ou velde te versprei onder verskillende bewerkings-metodes te evalueer. Die multi-veranderlike ANOVA resultate het aangetoon dat daar 'n beduidende verskil in O. pes-caprae digtheid tussen heuweltjie en nie-heuweltjie (persele) en verskillende bewerkings-metodes was. Daar was 'n beduidende verskil in die digtheid van o. pes-caprae tussen verskillende bewerkingsmetodes. 'n Post Hoc LSD toets het 'n beduidende verkil in die digtheid van bogrondse O. pes-caprae plante tussen kontrole terreine (geen versteuring) vergeleke met persele wat een of ander vorm van grondversteuring ondergaan het aangedui. Daar was egter geen beduidende verskil in die volopheid van 0. pes-caprae op persele wat een of ander vorm van versteuring ondergaan het (i.e Skoongemaakte vs Getilde vs Geskottelde vs Geploegde persele) op heuweltjies nie. Daar was 'n beduidende verskil in die aantal O. pes-caprae bolle wat versamel is tussen blokke (op en af van heuweltjies) en beduidende verskille tussen die bewerkings-metodes. Daar was ook 'n beduidende verskil in bol-deursnitte tussen bewerkings-metodes wanneer dit tussen heuweltjie en nie-heuweltjie persele vergelyk is. Die bolle is in vier metingsklasse verdeel. Die grootste aantal klein (2-5 mm deursnit) en medium (5-8 mm deursnit) bolle is in die Getilde bewerkings-metode gevind. In kontras het die Kontrole behandeling (onbewerk) die grootste aantal groot (14-17 mm deursnit) en medium bolle gehad. Samevattend het T. sinuata die potensiaal om gebruik te word in die rehabilitasie van ou lande in kombinasie met die tilting bewerkings-metode. Aandag moet geskenk word aan die effek van 0. pes-caprae, veral op heuwetjies waar hierdie spesies 'n totale dominansie in die rehabilitasie eksperiment getoon het.

Full textCientes do avanço global e da perda dos lugares de memória e identidade genuína de parte do património nacional, material e imaterial, pretendeu-se com este trabalho restituir e revitalizar a lembrança do que eram esses lugares. Vivemos num país enriquecido pela diferenciação cultural distinta em cada região territorial construída ao longo do tempo da nossa história. São traços identitários de culturas, expressos não só pelas construções vernaculares como também pela ação do homem nas paisagens humanizadas. Consequente do abandono e esquecimento de parte do interior do nosso país, identificamos a Região Saloia como símbolo desta problemática. Distinta pelas suas especificidades e identidade, cultural e arquitetónica, original. Com vista à requalificação desta região, elegeu-se o Casal do Rebolo (Almargem do Bispo, Sintra), como símbolo desta cultura vernácula. Desenvolveu-se a sua leitura fenomenológica, com base na experiência da realidade atual, identificando o seu sentido verdadeiro para dar continuidade ao significado original do lugar.
ABSTRACT: Being aware of the global advancement and of the loss of memory places and also those of genuine identity, part of the national heritage, material and non-material, the purpose of this work is to remember what those places used to be and to revitalise them. We live in a country enriched by the cultural differences in each territorial region built throughout our history. They are identity traits, shown not only in vernacular constructions but also through man’s action in humanized landscapes. The Saloia Region, included in part of the countryside abandoned and forgotten in our country, is identified as a symbol of this problematic. Its difference lies in its original specificity and identity, both culturally and architectonically. In order to rehabilitate this region, Casal do Rebolo (Almargem do Bispo, Sintra) has been selected as a symbol of this vernacular culture. A phenomenological approach has been taken, based on the current reality, identifying its true meaning so as to ensure the continuity of the original significance of the place.

Wetlands are increasingly recognised for their role in the provision of ecosystem services and contribution to global biodiversity. Despite this, more than half of the world’s wetlands have vanished or been degraded, primarily due to agriculture. Wetlands are constantly adjusting to disturbances occurring within them and within their surrounding landscape. It is important to recognise to what extent various disturbances affect wetlands when assessing disturbance and impact, and when considering wetland protection options. The benefit of the detailed characterisation of the sub-catchments of the Nuwejaars catchment is deepened understanding of how different combinations of land-uses and soils impact catchment hydrology, and ultimately, the wetlands within the catchment

Full textENGLISH ABSTRACT: Wetland systems provide vital hydrological ecosystem goods and services to mankind. When wetlands are transformed, through invasion by alien plants or replaced with agriculture, natural capital is lost, and the system is no longer able to provide the same quality of hydrological ecosystem services. Natural capital can be restored, but it involves substantial financial investment, and there is no guarantee that these hydrological ecosystem services will be fully recovered. This thesis aimed to investigate the hydrological impact of the land-cover changes in the Kromme River Catchment over the last 50 years, by using a combination of mapping and hydrological modelling techniques. We hypothesized that wetland loss in the Kromme has resulted in a shift in the flow regime, greater responsiveness to floods as a result of less storage, lower baseflow, and reduced water quality. We also hypothesised that the riparian invasion by Acacia mearnsii has caused flow reductions as a result of increased evaporation relative to the wetlands. Modelling results predict that over the past 50 years, the transformation of the floodplain wetlands in the Kromme River has shifted the flow regime, reducing baseflows and increasing the responsiveness of the catchment to extreme rainfall events. The invasion of A. mearnsii over time has also been predicted to have caused a reduction in river flow. Various restoration scenarios were considered, however if the Kromme were to be restored back to a land-cover state comparable to the 1950’s, 26.9 km2 (65.1%) of A. mearnsii would have to be cleared, and 5.2 km2 (34.2%) of the wetlands would have to be restored. The hydrological benefits would include a predicted increase in riverflow (42 mm/a), baseflow (2.9 mm/a), an increase in flood protection and improved water quality. This restoration strategy could be regarded as a type of insurance plan, and the benefits gained in terms of increased ecosystem service delivery would be the insurance premium. In conclusion it appears that restoration, insuring natural capital in the Kromme River, would provide significant economic returns on investment.
AFRIKAANSE OPSOMMING: Moeraslandstelsels voorsien die mens van noodsaaklike hidrologiese ekosisteemgoedere en -dienste. Wanneer moeraslande verander word, hetsy deur die indringing van uitheemse plante of vervanging met landboubedrywighede, gaan natuurlike kapitaal verlore en kan die stelsel nie meer dieselfde gehalte hidrologiese ekosisteemdienste lewer nie. Hoewel natuurlike kapitaal herwin kan word, behels dit beduidende finansiële belegging, en is daar boonop geen waarborg dat die hidrologiese ekosisteemdienste ten volle sal herstel nie. Hierdie tesis het ten doel gehad om die hidrologiese impak van die grondbedekkingsveranderinge in die Krommerivier-toeloopgebied oor die afgelope 50 jaar met behulp van ’n kombinasie van karterings- en hidrologiese modelleringstegnieke te ondersoek. Die hipotese was dat moeraslandverlies in die Kromme tot ’n verandering in die vloei-regime, hoër responsiwiteit op erge reënval as gevolg van minder bergingsruimte, ’n laer basisvloei en swakker watergehalte gelei het. Daar is voorts gehipoteseer dat die oewerindringing deur Acacia mearnsii ’n verlaging in vloei veroorsaak het weens ’n toename in verdamping uit die moeraslande. Modelleringsresultate dui daarop dat die transformasie van die vloedvlakte-moeraslande in die Krommerivier oor die afgelope 50 jaar die vloei-regime verander het, basisvloei verminder het en die toeloopgebied se responsiwiteit op erge reënval verhoog het. Die indringing van A. mearnsii het ook volgens aanduidings mettertyd ’n vermindering in riviervloei tot gevolg gehad. Verskeie herstelscenario’s is oorweeg. Om die grondbedekking in die Kromme te herstel tot wat dit in die 1950’s was, moet 26,9 km2 (65,1%) van die A. mearnsii verwyder en 5,2 km2 (34,2%) van die moerasland herwin word. Die hidrologiese voordele kan ’n verwagte toename in riviervloei (42 mm/a) en basisvloei (2,9 mm/a), ’n toename in vloedbeskerming sowel as beter watergehalte insluit. Hierdie herstelstrategie kan as ’n soort versekeringspolis beskou word, en die voordele verbonde aan beter ekosisteemdienslewering as die versekeringsuitbetalung. Ten slotte blyk dit dat die herstel van die Kromme, en die gepaardgaande versekering van natuurlike kapitaal, beduidende ekonomiese opbrengste op belegging sal meebring.

, in environmental scale. Therefore, the main aim of the thesis is to determine the principles and the tools of an urban conservation project within the context of environmental scale and to re-gain the unity of Yeni Galle Pazari Hani as much as possible by integrating it into the current atmosphere of Hanlar District in Bursa together with the traditional texture surrounding it. In this study, the insufficiency observed in preparatory stages of most of current restoration projects was emphasized. Hence, before intervention of such kind of traditional areas, it is aimed to take care of documentation, to make a comprehensive study on unobserved parts of traditional texture such as archeological excavation, and to form a worksheet containing principles and decisions for future studies that would be done under various disciplines. The proposal for the case of Yeni Galle Pazari Hani is significant as being composed of documentation, observation and decision parts of a proper intervention, although it can be accepted as an incomplete project, since being the first step of a comprehensive restoration project for the study area. In conclusion, this study exemplifies the documentation and the evaluation of the transformation in a historic commercial area and the suggestion to solve the general problems among the Historical Commercial Center of the cities by taking decisions on conservation and rehabilitation for the sustainability of the study area.

ENGLISH ABSTRACT: This study investigates the use of top-soiling, irrigation and translocating indigenous plants to facilitate the cost-effective return of a mined landscape to its former land-use (small stock farming) in an arid winter rainfall Succulent Karoo shrub land biome on the West Coast of South Africa. Effects of topsoil stockpiling and subsoil mineral concentration on soil fertility and chemistry were investigated, as soils are likely to determine rates of vegetation recovery on post-mined areas. Results of a radish bioassay show that stockpiling topsoil and mineral concentration subsoil decreased soil fertility. Mineral concentration decreased phosphorus, potassium, calcium, magnesium, carbon and nitrogen levels significantly relative to other soil treatments. Sodium in freshly deposited tailings was at potentially toxic levels and significantly higher than for all other soil treatments. Spreading of stockpiled topsoil over tailings may ameliorate harsh conditions created by mineral separation. Translocation of plants from pre-mined to post-mined areas was carried out on a trial basis in an effort to facilitate the return of natural vegetation and processes to strip-mined landscapes. Five local indigenous plant species: Asparagus spp., Ruschia versicolor, Othonna cylindrica, Lampranthus suavissimus and Zygophyllum morgsana were planted into multi-species clumps in a replicated experiment. Variables examined in the translocation trial included the effects of plant origin, soil treatment and/or irrigation on plant survival and establishment. The proportion of O. cylindrica transplants surviving for 15 months was greater than for other species. Whole plants survived better than salvaged plants, and Asparagus spp., R. versicolor, L. suavissimus and Z. morgsana survived better on stockpiled topsoil spread over tailings than on tailings alone. Irrigation had no consistent effect across species and treatment replicates. Salvaged-plant clumps were significantly larger than whole-plant clumps at planting, however, this effect was not observed after 12 months, indicating that whole-plant clumps grew faster than salvaged-plant clumps. The evergreen, leaf succulent shrubs O. cylindrica, L. suavissimus and R. versicolor appeared to be most suitable for large-scale translocation at Namakwa Sands. The return of biodiversity and changes in soil quality 15 months after translocation trials began were compared for combinations of top-soiling, irrigation, plant translocation and unmodified tailings. Irrigation may reduce biodiversity and seedling densities. Over a 15-month period following back filling and topsoil spreading, sodium, potassium and calcium appeared to return to levels observed for undisturbed soils. Magnesium remains at levels lower than in pre-mined soil conditions. Soil conditions may be more conducive to plant establishment and rehabilitation after back-filling of tailings and topsoil spreading. Electrical resistance increased over time indicating a reduction of free salts and salinity on rehabilitation sites. Phosphorus did not return to pre-disturbance levels, and carbon remained below pre-mining levels for at least 15 months after rehabilitation began, remaining a potential limiting factor in rehabilitation. Each rehabilitation technique that a mine employs has costs and benefits, and it is increasingly important that insights from ecology and economics are coupled if restoration efforts are going to succeed. A review of valuation systems indicates that Discounted Cash Flow Techniques (DCF) are suitable for valuation of rehabilitation operations.
AFRIKAANSE OPSOMMING: Hierdie studie ondersoek die gebruik van bogrond, besproeiing en die oorplanting van inheemse plante om die koste-effektiewe rehabilitasie van 'n stroopmynlandskap in die droë, winter reënval streek, Vetplant Karoo aan die Weskus van Suid-Afrika, wat vroeër gebruik is vir kleinvee boerdery, te bespoedig Die uitwerking van bogrondopberging en minerale konsentrasie op vrugbaarheid en chemise komposisie van grond is ondersoek, aangesien dié gronde gewoonlik die herstelspoed van plantegroei op 'n ou myn terein bepaal. Uitslae van radys proewe toon dat berging van bogrond en minerale konsentrasie van die onderliggende grond vrugbaarheid van grond laat afneem. Mynaktiwiteite en die minerale konsentrasie lei tot 'n betekenisvolle verlies aan fosfaat, kalium, kalsium, magnesium, koolstof en stikstof as die geval met ander bedrywighede. Die vlak van natrium in oorgeblywende sand na die minerale ekstraksie is hoogs giftig en is veel hoër as na ander bedrywighede. Die toediening van bogrond oor die oorblywende sand verbeter die toestand wat deur die skeiding van minerale veroorsaak is. Oorplasing van plante vanaf ongemynde na rehabilitasie gebiede is op proefbasis uitgevoer in 'n poging om die terugkeer van natuurlike plantegroei by die strookmyn te bespoedig. Vyf plaaslike inheemse plantspesies: Asparagus spp., Ruschia versicolor, Othonna cylindrical, Lampranthus suavissimus en Zygophyllum morgsana is in multi-spesie groepe geplant. Veranderlikes getoets tydens hierdie proef sluit in plantoorsprong, grond behandeling, en/of besproeiing, op die oorlewing en vestiging van plante. 'n Groter proporsie O. cylindrical as enige ander spesie het na 15 maande oorleef. Heel plante het beter oorleef as beskadigde plante. Asparagus spp., R. versicolor, L. suavissimus en Z. morgsana het beter oorleef op gebergde bogrond oor oorblywende sand as op oorblywende sand self. Besproeiing het nie 'n volgehoue uitwerking gehad op spesies of op herhaalde replisering nie. Beskadigde plantgroepe was groter as heelplant groepe toe hulle geplant is maar na 12 maande is opgemerk dat die heel-plante vinniger gegroei het. Die immergroen vetplante, 0. cylindrical, L. suavissimus en R. versicolor blyk die mees geskik vir grootskaalse oorplanting by Namakwa Sands. Herstel van biodiversiteit en veranderings in grondeienskappe 15 maande na proewe begin het, is vergelyk m.b.t. die toediening van bogrond, besproeiing, oorplanting en onbehandelde oorblywende sand. Besproeiing kan biodiversiteit en digtheid van saailinge verminder. Vyvtien maande na opvulling en die toediening van bogrond, het kalium, natrium en kalsium teruggekeer na vlakke in onversteurde grond. Magnesium vlakke was nog altyd laer as dié voordat mynaktiwiteite aangevang is. Terugplasing van sand en toediening van bogrond mag die vestiging en rehabilitasie van plante bespoedig. Weerstand vermeerder met tyd wat 'n verlaaging in vry soute en soutagtigheid in die grond wat gebruik is vir rehabilitasie aantoon. Fosfor het nie teruggekeer tot vlakke van voorheen nie en vlakke van koolstofhet na 15 maande verlaag gebly, en kan die potential tot rehabilitasie belemmer. Elke rehabilitasie tegniek wat die myn gebruik bring kostes sowel as voordele mee. Om restorasie pogings te laat slaag moet insigte vanaf ekologie en ekonomie saam ingespan word. 'n Oorsig van waardasie sisteme toon dat Afslag Kontant Vloei Tegnieke geskik is vir die evaluasie van rehabilitasie programme.

Full textThis work presents an automated system for fresh vegetable food conservation based on electronic instrumentation, a storage chamber, and software for system control, whose procedures were developed in LabView. For conservation the fresh packaged products are stored into a controlled temperature liquid volume (55.3 liters), i.e., an aqueous solution prepared with water and ethylene glycol (2%). This conservation methodology allows to increase shelf time of fresh vegetables by means of reducing the storage temperature range to a safe operating condition without freezing the products. Results have shown the suitability of the developed system, which enables to store fresh products with safety and preserving quality as close as 0.4°C of the freezing point. In a conventional chamber fresh products must be stored considering at least a safety range of 2.0°C, which is much farther from the freezing point. Therefore, these conditions give to the hydro-conservation system large immunity regarding thermal load perturbation as well during door operation and adequate speed for fast cooling processes for fresh products.

The jacutinga (Aburria jacutinga) is a large frugivore bird in the process of extinction primarily by hunting and habitat destruction. Endemic of Atlantic Forest, currently has limited distribution and isolated populations. For this reason, is the focus of some conservation programs aimed at the captive-breeding for later release and/or reintroduction into unique environments of the species. This study used behavioral assessments in a pre-release rearing system, and promoted training aimed at food aspects and predator recognition. It was observed 31 jacutingas and produced a ethogram with 68 behavioral acts, grouped into eight categories. After, were held training sessions to food type and antipredator type. Food training intended to assess food acceptance and promotion of foraging behavior. It offered 32 different food items, six of which were not accepted. It was noticed diversification acceptance of food items, especially fruits and seeds up to 20 mm, but also leaves and flowers. For foraging behaviors observed, as the capture and handling of food items, they are performed only when the jacutinga achieves the item with its beak. This may be the reason for the jacutingas remain for long periods in the same tree, when it finds items for their food. For the antipredator training it were used three models of predators: a feline (Leopardus tigrinus), one raptor (Pseudastur polionotus) and domestic dogs. In these training sessions were observed eight jacutingas. Both training sessions were positive, with behavioral responses of surveillance and defense to the models used. Also, memory tests were performed where the same models were presented for jacutingas, after 30 days of training. The results of the memory tests indicate that there was a learning result of antipredator training. The jacutingas showed the expected responses (similar to the training) when the models were presented. It highlights the importance of the work, because the results are assisting in the rehabilitation process of individuals to be used in future releases. The entire process developed in this study is being used experimentally as a pilot in" Protocolo de Soltura de Jacutingas " coordinated by SAVE Brazil. The training and the tests are intended to increase the survival rate of birds used in release programs, through techniques that enhance and/or induce the production of behaviors that express survival skills in nature; in this case, foraging skills and predator recognition as behavioral indicators to obtain individual fitness.
A jacutinga (Aburria jacutinga) é uma espécie de ave frugívora de grande porte em processo de extinção devido principalmente à caça e destruição do hábitat. Endêmica da Mata Atlântica, encontra-se atualmente com distribuição bem reduzida e com populações isoladas, sendo foco de alguns programas de conservação, que visam a criação em cativeiro, para sua posterior soltura e/ou reintrodução em ambientes originais da espécie. O presente trabalho utilizou de avaliações comportamentais, em um sistema de criação pré-soltura,promoveu treinamentos visando aspectos alimentares e de reconhecimento de predador. Foram observadas 31 jacutingas e elaborado um etograma com 68 atos comportamentais, agrupados em oito categorias. Depois, realizou-se os treinamentos do tipo alimentar e antipredação. Os treinamentos alimentares visaram a avaliação da aceitação alimentar e promoção de comportamentos de forrageio. Foram oferecidos 32 itens alimentares diferentes, dos quais seis não foram aceitos. Percebeu-se uma diversificação na aceitação de itens alimentares, em especial frutos e sementes com até 20 mm, mas também folhas e flores. Já os comportamentos de forrageio observados, como captura e manipulação dos itens alimentares, são realizados somente quando a jacutinga alcança o item com seu bico. Esse pode ser o motivo das jacutingas ficarem por grandes períodos numa mesma árvore, quando localiza itens de sua alimentação. Como treinamento antipredação foram utilizados três modelos de predadores: um felino (Leopardus tigrinus), um rapinante (Pseudastur polionotus) e cão doméstico. Nestes treinamentos foram observadas oito jacutingas. Ambos os treinamentos mostraram-se positivos, apresentando respostas comportamentais de vigilância e defesa aos modelos utilizados. Também foram realizados testes de memória, onde se apresentavam os mesmos modelos as jacutingas, após 30 dias do treinamento. Os resultados dos testes de memória indicam que houve um aprendizado, resultante dos treinamentos antipredação. As jacutingas apresentaram as respostas esperadas (semelhantes às observadas nos treinamentos), quando apresentados os modelos utilizados nos treinamentos. Destaca-se a importância do trabalho desenvolvido, pois os resultados obtidos estão auxiliando no processo de reabilitação de indivíduos a serem utilizados em futuras solturas. Todo o processo desenvolvido nesse projeto está sendo utilizado experimentalmente como piloto no “Protocolo de Soltura de Jacutingas”, coordenado pela SAVE Brasil. Os treinamentos e testes aplicados visam aumentar a taxa de sobrevivência das aves utilizadas em programas de soltura, por meio de técnicas que reforcem e/ou induzamapresentação de comportamentos que expressem habilidades de sobrevivência em natureza; no caso, habilidades de forrageio e reconhecimento de predador como indicadores comportamentais para obtenção de fitness individuais.

Tem como objectivo identificar e analisar o impacto da relação monumento/lugar resultante da aplicação de processos e opções em projecto, no âmbito da reabilitação patrimonial contemporânea, cuja acção prática resultou na transformação de características de contexto, tanto das partes como do conjunto – monumento, espaço público e envolvente. O espaço público é visto como ponto de relação entre a preservação do edificado, tanto monumental como habitacional, e a aplicação de políticas económicas de desenvolvimento dos lugares, não esquecendo as iniciativas de preservação dos valores históricos intrínsecos. Este estudo permite interpretar e identificar diversas soluções em projecto, com recurso a casos específicos, explicitando conceitos e ideias casuísticas de recuperação do património edificado que de alguma maneira implicaram efeitos no espaço público e no tecido construído, organizados por categorias. São assim agrupados ‘tipos’ de intervenção, representativos das diferentes especificidades históricas e culturais de cada lugar, com sedimentação de factores de contexto que pretendem potencializar e valorizar o monumento, encontrando para cada caso uma solução própria. Complementarmente, propõe-se reconhecer o contributo metodológico interventivo do arquitecto contemporâneo, na protecção dos valores conservacionistas e na valorização do património em Portugal.
Monument and Place. The relation between public space and monument in the contemporary heritage sites intervention. This work deals with the theme of the built heritage articulating the monument with his public space in particular, the relationship between buildings and the urban fabric and landscapes where they stand, evaluating the different types of intervention and possible interactions between them. It aims to identify and analyse the impact of the relationship monument/place which results from processes and project options as part of contemporary heritage rehabilitation, which practical action resulted in the transformation of the characteristics of context, both the parts and the whole – monument, public space and environment. Public space is seen as a point of connection between the preservation of buildings, both monumental and housing, and implementation of economic policies for the development of places, not forgetting the efforts of preservation of historical values intrinsic. This study allows us to interpret and identify various solutions in design, using specific cases, concepts and ideas casuistic for recovery of the built heritage that somehow implied effects on public space and the built fabric, organized by category. Thus are grouped ‘types’ of intervention, representative of different historical and cultural particularities of each place, sedimentation of context factors that aim to enhance the monument, finding in each case a specific solution. In addition, it is proposed to recognize the methodological intervention contribution of each contemporary architect, on the protection of conservation values and perpetuating the heritage in Portugal.

ABSTRACT: Knowing that the abandoned places concerning the railway panorama are a reality in our country, as also in Europe and outside it; and because it is considered the deteriorating residual property a problematic that has been object of discussion, interested in its preservation, from the population residing in the zone corresponding to that built to the abandonment, as well as professionals in the area of architecture, and the municipalities to which they are associated. The present work takes into account the general panorama in Portugal, in a macro approach, with the aim of identifying through a survey as broad as possible, the railway assets already rehabilitated for new functions currently in force, and in a narrower/micro vision, focuses on the Caceres Branch, whose deactivation occurred in 2011, and its former stations, currently rehabilitated on the basis of a similar program, "rural tourism", that through different assumptions, as in the case of the building supporting for the former station of Beirã and the former station of Castelo de Vide, apparently two cases of success. The first example is a conservation project and the second is a rehabilitation case, being both a strategy to replicate elsewhere, in favor of heritage, spaces of memories, capable of adapted cases resisting time.

Full textMany efforts have been dedicated in the searching of natural compounds which are suitable to be applied in food conservation. Among them, the chitosan has presented promising results concerning the antimicrobial activity, structural preservation and delay of fruits senescence. However, the chitosan, as found commercially, is soluble only in acidic medium solutions what is considered a hindrance for fully applications as food conservative. In this sense, chitosan derivations which are able to be solubilized in neutral pH have been developed. The N,N,N Trimethylchitosan (TMC) is one of them, characterized as a hydrosoluble derivative of chitosan, which has been considered as an efficient antimicrobial agent with positive action as fresh food conservative. The aim of the present was the evaluation of the antimicrobial activity of the TMC against Gram-positive and Gram-negative bacteria and filament fungi. The TMC antimicrobial activity was assessed by comparing with the Commercial Chitosan (CC), by means of the determination of the Minimum Inhibitory Concentration (MIC), following the Clinical and Laboratory Standards Institute (CLSI) according to M7-A6 (NCCLS, 2003) and M38-A (NCCLS, 2002) standards, both recognized by the Agência Nacional de Vigilância Sanitária (ANVISA). Additionally, the TMC and CC antifungal activity was carried out by recoding the visual fungi growth and estimated from the percentage of infected samples by the fungy on cut faces of grape-tomatoes (Solanum lycopersicum variety cerasiforme), in coated and non-coated conditions, along seven days of incubation. The results concerning antibacterial activity points to a greater action of the TMC when comparing to some analysis performed on CC coating against four of the six strains analyzed: Enterococcus faecalis, Staphylococcus aureus, Escherichia coli and Salmonella enterica. Nevetheless the CC antifungal activity was considerable superior to that observed to TMC for three different fungi tested: Penicillium sp., Aspergillus flavus standard and Aspergillus flavus wild. However, both polymers showed high antibacterial and antifungal activity and are therefore considered as natural agents with relevant antimicrobial potential for the fresh food conservation.
Muitos têm sido os esforços pela procura de substâncias naturais que possam ser aplicadas à conservação de alimentos. Dentre as substâncias em estudo, a quitosana tem apresentado resultados promissores tanto com relação à atividade antimicrobiana quanto na manutenção estrutural de alimentos e redução da senescência em frutos. No entanto, a quitosana, em sua forma comercial, é solúvel apenas em soluções ácidas diluídas, o que dificulta sua plena utilização como conservante alimentício. Dessa forma, derivados de quitosana que apresentem capacidade de solubilização em pH neutro têm sido desenvolvidos. Dentre esses derivados a N,N,N-trimetilquitosana (TMQ), um polímero hidrossolúvel derivado da quitosana, tem sido avaliado como promissor agente antimicrobiano e conservador de alimentos frescos. Assim, o presente projeto teve como objetivo avaliar a atividade antimicrobiana da N,N,N-trimetilquitosana sobre o crescimento de bactérias Gram-positivas e Gram-negativas e de fungos filamentosos. A atividade antimicrobiana da TMQ foi avaliada mediante comparação com a Quitosana Comercial (QC) pela determinação das Concentrações Inibitórias Mínimas (CIM) a partir de testes padronizados pela Clinical and Laboratory Standards Institute (CLSI), segundo suas normas M7-A6 (NCCLS, 2003) e M38-A (NCCLS, 2002), ambas reconhecidas pela Agência Nacional de Vigilância Sanitária (ANVISA). Além disso, a avaliação da atividade antifúngica das substâncias foi realizada mediante leitura visual e estimada a partir do percentual de amostras infectadas pelos fungos sobre fatias de tomatecereja (Solanum lycopersicum variedade cerasiforme) revestidas e não revestidas, ao longo de sete dias de incubação. Os resultados indicaram uma maior atividade antibacteriana da TMQ em relação à QC para quatro das seis cepas bacterianas analisadas: Enterococcus faecalis, Staphylococcus aureus, Escherichia coli e Salmonella enterica. No entanto, a atividade antifúngica da QC superou a da TMQ para os três fungos testados: Penicillium sp., Aspergillus flavus padrão e Aspergillus flavus selvagem. Entretanto, ambos os polímeros avaliados apresentaram atividade antibacteriana e antifúngica satisfatória sendo, portanto, considerados como agentes naturais com potencial antimicrobiano relevante para a conservação de alimentos frescos.

Full textThe objective of this thesis is to evaluate the local implementation of the safeguard policies of urban heritage medina in Tunisia. We will question these policies through their roles in the territory and to understand their effects on historic centers. Our approach consists in a comparison to the local application of safeguard policies, through case rehabilitation projects and backup done in Tunisian Medinas. We trace the birth of these public instruments to its implementation by the various actors and we confront local realities. We finally state the place of the involvement of the social dimension in safeguarding projects
