The purpose of this research study was to conduct an ethnographic assessment for an Environmental Impact Statement (EIS) of a proposed expansion plan for the Santa Fe Ski Area located in the Sangre de Cristo Mountains north of Santa Fe, New Mexico. Along with expansion into forest areas outside the existing Special Use permit boundaries, the proposed plan includes new buildings, parking lots, lifts, ski runs, and snowmaking within the existing ski area boundary. The ethnographic assessment concentrates on those cultural resources known to be in the area, as identified by Pueblo participants in the research study. This project had three objectives: a) what impact would the project have on the traditional uses, cultural uses, values, and belief practices of Tesuque Pueblo and other Pueblos' uses of the area; b) how would the ski area expansion affect the traditional use area of the Tesuque Pueblo and other Pueblos; and c) what specific areas of traditional cultural use, including those of Hispanic origin, would be affected by the proposed alternatives.

The extraction of raw materials has environmental impacts. Forestry and the extraction of coal, oil, natural gas, gold and other minerals can have serious impacts on the environment. Exploration and evaluation, development activities, production and mine closure result in high costs. The years of waiting between the start of exploration, commencement of production and mine closure create specific challenges in accounting for mining organisations. Most of the damages caused by mining activities cannot be hidden because of the processes involved, it is best to prevent it rather than avoidance. It is important to implement Environmental Management Accounting (EMA), which will assist in presenting a decision-making system for corporations. The system measures and promotes environmental performance by identifying effective cost assessment structures. This study assessed the awareness of environmental management accounting in the mining industry. An analytical methodology was used. A questionnaire was administered to a selected group of participants. It was based on the employee’s understanding of their organisation’s practices or point of view on environmental issues to build a case about the awareness of environmental management accounting. Selected participants were mine management or mine production personnel, financial practitioners and environmental practitioners from different mining organisations in the Gauteng, Mpumalanga and North-West provinces of the Republic of South Africa. All participants in the study are employees in the mining industry. Mine management is less aware of environmental management accounting compared to environmental and financial practitioners. Mine production personnel only perceive environmental issues as costs to the operations. This group rated compliance with regulation as the main driver for their organisation’s environmental management system. Gauteng province is more aware of environmental management accounting compared to Mpumalanga and North West provinces. Organisations with high annual turnover tend to disclose more financial environmental information than those with low annual turnover. Organisations explain and classify environment-related costs differently according to the intended use of the cost information. There are standards and measures to collect and record environmental and accounting information stipulated in ISO14001 including environmental management systems (EMS) in different organisations. Systems and measures put in place ensure good environmental performance in the mining operations. The tracking and reduction in the amount of energy, water and materials used by organisations may result in environmental benefits. Employees should have environmental cost information associated with their operations in order to minimise environmental impacts of an organisation. The findings of the study indicated low levels of awareness of environmental management accounting in the mining industry; however, there is a higher level of awareness of environmental impacts and costs, environmental management system and financial environmental information. The level of rating at which organisations generate and record physical and monetary information of environmental management accounting is higher. / MBAm, North-West University, Potchefstroom Campus, 2014

It is generally accepted that the environment has three inter-dependent components: economic, socio-political and natural Consequently, integrated environmental management coupled with sustainable development is critical, and in order to achieve this goal, effective guidelines and implementable legislation are necessary. This evaluation aims to determine and compare the effectiveness of the South African and Malawian environmental impact assessment (EIA) legislation, using the comparative criteria set out by Wood (1995, 2003), and accordingly to determine whether any further amendments are necessary to improve the effectiveness of these countries' EIA systems. In the Southern African Development Community (SADC) region, it is particularly important that environmental legislation and policies are aligned across borders, to allow for better integration of these economies. The alignment of EIA systems in the SADC region could enhance regional sustainable development if managed using similar criteria. The primary objective of this study is to compare the EIA legislation of South Africa and Malawi using Wood's (1995, 1999, 2003) 14-point evaluation criteria. The effectiveness and not the implementation and practice of the legislation is being compared. The secondary objective of this study is to determine whether Wood and Roux's recommendations have been incorporated into the South African National Environmental Management Amendment Act 8 of 2004 and the January 2005 draft EIA regulations, and whether South African legislation meets Wood's 14 criteria for a sound EIA system. In the South African evaluation, 11 of Wood's 14 criteria are met, while an additional two criteria are partially met and one criterion is failed, resulting in an overall improvement in the South African EIA system. The Malawian EIA legislation meets 11 of Wood's 14 criteria, with three criteria being partially met, in principle making it more effective than the South African EIA legislation. However, although Malawi theoretically has a slightly more effective EIA legislation than South Africa, in practice this is not the case. Ideally, when South Africa's updated EIA legislation is published it will meet with all 14 of Wood's criteria for an effective EIA system based on international standards. / Thesis (M.

In an accident, some seatbelt is let out by the seatbelt retractor in the vehicle. This is done to minimize the chest pressure and for the occupant to correctly impact the air bag. In an adaptive load limiter (LLA) the force in the seatbelt could be changed between different levels. In this way the chest pressure and the speed in to the air bag can be optimized and to minimize injuries.The work has been aimed at develop new concept of switching between the high and low force. The goal is to reduce the number of parts, the complexity and the size of the components. The LLA device today is made out of nine components.This work has included brainstorming for ideas of new concepts. The concept have been sketched. The three best concepts have been valued in a concept evaluation matrix. CAD- models have been done. Calculations have been done by hand to see which forces the components will be subjected to. FEM-calculations have also been done to see that components can handle the amount of stress they which they will be subjected to during the switching. Tests of components have also been made to verify the concept on Autolivs test center. The results were then evaluated. The work is ended by recommendations of further development.This thesis has been done on Autoliv Sweden AB in Vårgårda. Autoliv was founded in 1953 in Vårgårda of the two brothers Lennart and Stig Lindblad. Autoliv is world- leading in car safety. Autoliv is currently operating in 27 countries and has over 70 000 employees. They save over 30 000 lives and prevent over 300 000 injuries every year. Autoliv has made seatbelts since 1956. / Vid en krock släpper en bältesrulle i ett fordon ut lite bälte för att personen i sätet skall landa rätt i krockkudden och där med minska tryckskadorna på hen. I en bältesrulle med en adaptiv kraftbegränsare kan kraften i bältet varieras mellan två olika lägen av en växlingsmekanism. På det sättet minimeras trycket på bröstkorgen och hastigheten in i krockkudden kan optimeras.Arbetet har riktats mot att ta fram nya koncept för att växla mellan krafterna. Syftet med det har varit att försöka få ner antalet, minska storleken och komplexiteten på komponenterna i en adaptiv kraftbegränsare. Dagens konstruktion på kraftbegränsare innefattar nio komponenter.Arbetet har innefattat brainstorming för att ta fram nya koncept. Skisser av dessa koncept är gjorda. De tre bästa koncepten har sedan utvärderats i en konceptutvärderingsmatris. CAD- modeller är därefter framtaget. Handberäkningar för att se vilka krafter som komponenter utsätts har genomförts. FEM- beräkningar har gjorts för att se att delar inte går sönder. Provning av komponenter och funktioner är har gjorts på Autolivs test center i Vårgårda.

Barragens de rejeitos são estruturas que têm a finalidade de reter os resíduos sólidos e água dos processos de beneficiamento de minério. Seu planejamento inicia com a procura do local para implantação, etapa na qual se deve vincular todo tipo de variáveis que direta ou indiretamente influenciam a obra: características geológicas, hidrológicas, topográficas, geotécnicas, ambientais, sociais, avaliação de riscos, entre outras. Este trabalho apresenta um estudo sobre a utilização do método de analise hierárquica como apoio na tomada de decisões para seleção de locais para barragens de rejeitos. A revisão bibliográfica de fatores que influem nesta etapa de decisão resultou em indicadores claros de avaliação, que foram orientadores para a coleta de dados no estudo de caso. O estudo de caso consistiu na avaliação de três locais para a localização da nova barragem de rejeitos de beneficiamento de cobre a ser construída pela MINER S.A. no município de Carmen de Atrato, na Colômbia. Para a seleção do local entre três alternativas, foram considerados dois aspectos: custo inicial total e impacto ambiental. Na aplicação do método de análise hierárquica, o objetivo principal da hierarquia proposta foi o menor impacto ambiental, considerando-se as três causas consideradas mais importantes: implantação da barragem, ruptura da barragem e transporte de rejeitos da usina ao local de disposição. Foram analisados os impactos potenciais na água, solo, fauna, flora e ocupação humana. Os custos foram tratados separadamente. No final foi realizada uma análise conjunta dos custos iniciais totais e dos resultados do método de análise hierárquica, para servir como apoio ao tomador de decisão. Foi também realizada uma análise de sensibilidade, que mostra a influência significativa de um dos critérios nos pesos finais dos locais avaliados. / Tailings dams are structures designed to retain solid wastes and water generated in the processing of metal ore. The overall planning of these dams starts with site selection, step in which all directly or indirectly influential variables should be considered: geological, hydrological, topographic, geotechnical, environmental and social characteristics, risk evaluation etc. This work presents a study of the utilization of the hierarchy analysis process (AHP) as a tool for decision-making in the selection of sites for tailings dams. The bibliographic review of relevant factors resulted in the proposal of a list of indicators, which was very useful as an orientation for data collection in the study case, and is considered as an important contribution from this research. The study case consisted in the location of the new copper tailings dam of MINER Inc. in Carmen de Atrato, Colombia. Initially, a geochemical software was applied to the region to discard unsuitable areas. For the selection of a site among three resulting alternatives, two aspects were taken into account: total initial cost and environmental impact. In the application of AHP, the main objective of the proposed hierarchy was the lowest environmental impact. Three possible causes were considered as the most important concerning environmental impact: dam and reservoir occupancy, dam collapse and transportation of wastes from the plant to the disposal site. Potential impacts on water, soil, fauna, flora and human occupation were analyzed. Costs were treated separately. Finally, a joint analysis of total initial costs and results from the AHP application was carried out in order to convey a support for the decision maker. A sensilibtily analysis was also performed to show the influence of one of the subcriteria on the final alternatives weights.

Resumo: Chorume é um líquido produzido durante a decomposição anaeróbia dos resíduos sólidos que tem potencial impacto ao ambiente devido a larga variedade de substâncias orgânicas e inorgânicas contidas nesta matriz. Dessa forma, o presente estudo apresenta a caracterização e estudo térmico de amostras de chorume de diferentes procedências as quais foram coletadas nos aterros de Araraquara (CA), São Carlos (CSC), Campinas (CC) e da usina de compostagem na Vila Leopoldina-SP (CSP). Adicionalmente foram estudados os extratos solúveis (ES) obtidos de composto maturado (CM) e o chorume de sistemas anaeróbios (SA1 e SA2) preenchidos com resíduos sólidos provenientes de restaurante universitário simulando as condições acidogênicas de decomposição anaeróbia de aterros. Os resultados obtidos da análise térmica (TG, DTA e DSC) evidenciaram que as amostras de chorume com características acidogênicas (CC, SA1, SA2) apresentaram-se menos estáveis termicamente quando comparadas as CA e CSP que estão em condições metanogênicas. O método isoconversional de Flynn-Wall permitiu a determinação dos parâmetros cinéticos (E e A) para reações de desidratação em intervalos fixos de temperatura. Os valores de E e lnA associados ao procedimento desenvolvido por Málek e Koga conduziu ao modelo mais aproximado para as reações em estudo. O modelo cinético SB (Sesták- Berggren) foi indicado para as reações de decomposição das amostras de extratos solúveis do composto maturado, chorume e derivados. Para a primeira e segunda reação de decomposição térmica do composto maturado os modelos cinéticos mais aproximados foram RO e JMA (n<1) respectivamente. A relação linear entre lnA versus E foi verificada para grupos de reações constatando o chamado efeito de compensação cinética (KCE) . Nas análises de metais pesados realizadas em algumas amostras...

Thus, this study presents the chemical characterization and thermal study of the leachate samples from different backgrounds which were collected in landfills of Araraquara (CA), São Carlos (CSC), Campinas (CC) and composting usine from Vila Leopoldina-SP (CSP). Additionally it was also studied the soluble extract (ES) obtained from matured compound (CM), and leachate from anaerobic systems (SA1 and SA2) filled with solid residues from the university restaurant simulating the acidogenic conditions of anaerobic decomposition of the landfills. The obtained results of the TG, DTA and DSC curves showed that, leachate samples with acidogenic characteristics (CC, SA1 and SA2) presented less thermal stability when compared with CA and CSP, which are in metanogenic conditions. Flynn-Wall isoconversional method allowed the determination of the kinetic parameters (E and A) to dehydration reactions in fixed range of temperature. The E and lnA values associated to the procedures of Málek and Koga lead to the most appropriate model to the reaction in study. SB kinetic model was indicated to the decomposition reactions to soluble extract of matured compound, leachate and derivates. To the first and second reaction of thermal decomposition of matured compound, RO and JMA (n<1) were the more approximate kinetic models, respectively. The linear relationship between lnA vs. E was verified for groups of reactions, noting the so-called kinetic compensation effect (KCE). In the analysis of heavy metals, held in some leachate samples were detected concentrations of Mn, that exceed the maximum values allowed. Phenols, phthalates, bisphenol A...

O presente estudo analisa a água da bacia do alto Tietê, tanto como insumo na forma de água potável produzido em oito Estações de Tratamento de Água (ETA), quanto insumo na forma de energia hidráulica, ou ainda, como água residuária gerada por diferentes atividades de origem antrópica. O maior problema desta bacia é a água residuária que é lançada nos rio Tietê e Pinheiros devido ao déficit de 32,41 m3/s (2008) no tratamento de esgoto da Região Metropolitana de São Paulo (RMSP) o qual produz uma carga poluidora de 920 mil kg de DBO/dia. As águas urbanas que passam pelo canal do rio Pinheiros no período de cheias e de seca têm o mesmo destino que é o reservatório Billings. No entanto, os atos institucionais que permitem a operação de bombeamento da água para o reservatório são distintos. O primeiro caso ocorre pela ação de controle de cheia da RMSP e está apoiada na Resolução Conjunta de Secretarias de Estado de São Paulo (SEE- SMASRHSO em 13/03/96) que permite o bombeamento das águas nas seguintes situações de emergência: (1) previsão de vazão do rio Tietê no ponto de sua confluência com o rio Pinheiros, acima de 160 m3/s. (2) sobrelevação superior a 30 cm de nível d´água na confluência com o rio Pinheiros. No segundo caso, a Empresa Metropolitana de Águas e Energia (EMAE) propôs o Projeto Flotação à Secretaria de Estado do Meio Ambiente (SMA, 2004) para tratar 10 m3/s de águas originárias do canal de Pinheiros (set/2007 a set/2008) por meio da tecnologia de Flotação em Fluxo. Usando-se como base em informações do Plano de Tratamento de Esgoto para a grande São Paulo (SANEGRAN) e dados da operação do protótipo de flotação do Sistema Pinheiros-Billings (Projeto QAPB), concluiu-se que o impacto ambiental causado no reservatório Billings pela carga de poluentes (massa por segundo) bombeada após a flotação da água do rio Pinheiros foi sempre menor do que aquela observada na operação controle de cheias. O tratamento por flotação apresentou remoção de 91% para o fósforo total, 90% para o E.coli, 53% para a matéria orgânica e 14% para o nitrogênio amoniacal. Observou-se um aumento de 34% para o oxigênio e uma diminuição de 46% na turbidez. A análise da viabilidade técnica da operação do Sistema Elevatório Tietê-Billings realizada pelo Método AHP-Analitic Hierarchy Process, demonstrou que 65,62% da água que entra no reservatório Billings pode ser utilizada para gerar energia elétrica, enquanto que 34,38% desta água pode ser utilizada no abastecimento da RMSP. O estudo da viabilidade econômica comparou o custo do processo flotação com o custo de aporte de água proveniente de outros mananciais e demonstrou que o custo da operação de flotação das águas do rio Pinheiros para servir ao abastecimento da RMSP é economicamente viável. / This study examines the characteristics of the water from the upper Tietê, as an input in the form of drinking water produced in eight stations, water treatment plant (WTP), an input for hydropower generation and wastewater generated by different anthropogenic activities. The most important problem of this basin is the wastewater that is released in the Pinheiros river and due to the deficit of 32.41 m3/s (2008) in the treatment of sewage in the metropolitan region of São Paulo (RMSP) which produces one pollutant load of 920 thousand kilograms of BOD per day. The Pinheiros rivers flow during the floods and drought has the same destination, the Billings reservoir. However, the legislation for floods and drought periods are different. The first case - floods occurs by the action of full control of the metropolitan region and is supported by the Joint Resolution of Secretaries of State of Sao Paulo (SEE-SMA-SRHSO on 13/03/96) that allows the pumping of water in the following emergencies: (1) estimates of flow of the Tietê river at the point of its confluence with the river Pinheiros, above 160 m3/ s; (2) raised level above 30 cm water level at the confluence with the river Pinheiros. The second case - drought, the Metropolitan Company for Water and Energy (EMAE) Project proposed flotation of the Secretary of State for the Environment (SMA, 2004) to treat 10 m3/ s water originating channel Pinheiros (set/2007 the set / 2008) by means of flotation technology in flow. Using information based on Environmental Sanitation Great São Paulo (SANEGRAN) and data from the operation of the prototype flotation system Pinheiros-Billings (Project QAPB), concluded that the environmental impact of the reservoir Billings for the load of pollutants (mass per second) pumped after the flotation of the Pinheiros river water was always lower than that observed in the flood control operation. The treatment presented by flotation removal of 91% for total phosphorus, 90% for E. coli, 53% for organic matter and 14% for ammonia nitrogen. There was an increase of 34% for oxygen and a decrease of 46% in turbidity. The analysis of the technical operation of the lift system Tietê-Billings, held in the AHP-Analytic Hierarchy Process, showed that 65.62% of the water entering the reservoir Billings can be used to generate electricity, while 34.38% this water can be used to supply the ´´RMSP´´. The feasibility study compared the economic cost of the flotation process with the cost of input of water from other sources and concluded that the cost of the flotation of the waters of the Pinheiros river to serve the supply of the metropolitan region is economically viable.
