Abstract:
Volcanic gases carry valuable information about processes occurring at active volcanoes, and so their accurate measurement and analysis are highly desirable. Masaya is a low-lying persistently active basaltic volcano, which is renowned for strong passive gas emission unaccompanied by lava extrusion, although it has also undergone plinian eruptions in the past. Its consistent behaviour sustains a reliable tropospheric plume, making it an ideal location at which to study volcanic degassing. During February-March 1998 and March 1999, Masaya's gas plume composition was investigated using the new g

The emission of greenhouse gases (GHG) is currently intensely debated issue. Countries with reduction targets of GHG emissions have developed studies to understand the processes and reduce the emissions. Farming is the main source of GHG emissions in Brazil. Among the main products of Brazilian agriculture is cattle, handled mainly in the extensive system, where animals are slaughtered at an average of three to four years and grassland receives little or no cultural tract. Quantification and monitoring of GHG emissions in agricultural systems enable the evaluation of the degree of impact on th

Introdução. O aquecimento global resultante do aumento nas concentrações de gases de efeito estufa (GEE) é um dos principais problemas ambientais que o mundo enfrenta atualmente. Atividades humanas estão alterando a composição da atmosfera através da emissão de GEE, particularmente dióxido de carbono (CO2), metano (CH4), óxido nitroso (N2O). Os veículos automotores são uma importante fonte de emissão desses gases, tanto diretamente, através da emissão de gases pelo escapamento, como também através das emissões oriundas do processo de produção e manipulação dos combustíveis usados pelos mesmos.

Low Emission Vehicles (LEVs) represent a car classification which utilizes advancements in automotive technology to address policy objectives associated with energy security and greenhouse gas emissions. The effectiveness of LEVs at addressing these objectives will not only depend on their technical performance but also on their levels of adoption by consumers. With LEVs encompassing cars which are significantly different compared to conventional market options, the understanding of consumer response to these vehicles remains limited.

In this dissertation, I present that at a vacuum of 3×10-7 Torr, residual O2, CO2, H2 and Ar exposure do not significantly degrade the field emission (FE) properties of ZnO nanorods, but N2 exposure significantly does. I propose that this could be due to the dissociation of N2 into atomic nitrogen species and the reaction of such species with ZnO. I also present the effects of O2, CO2, H2O, N2, H2, and Ar residual gas exposure on the FE properties of GaN and ZnS nanostructure. A brief review of growth of ZnO, GaN and ZnS is provided.

An important step in the more efficient use of PICA (Phenolic Impregnated Carbon Ablator) as a Thermal Protection System (TPS) material for spacecraft is the understanding of its pyrolysis mechanics. The gases released during pyrolysis and their subsequent interaction with the reactive plasma environment is not yet well understood. The surface recession of PICA as it ablates during testing only makes the study and characterization of the chemical reactions more difficult. To this end, a probe has been designed for this study to simulate, in steady state, the pyrolysis gases within the UVM 30kW

The increase in greenhouse gas (GHG) concentrations in the atmosphere, as well as the high rate of depletion of hydrocarbon-based resources have become a global concern. A major source of emissions of hydrocarbon vapours occur during loading and offloading operations in crude oil shuttle tanker transportation. The emitted gases have a typical composition of 60 % N2, 10 % CO2, 5% O2, 5 % C3H8, 10% CH4, 5% C2H6 and 5 % higher hydrocarbons. As a result, various methods aimed to add value to GHG to produce valuable fuels and chemical feedstock are being developed. This work incorporates the use of

This work focuses on the actions sought by the authorities to minimize global climate problems that are currently changing the conditions of survival of the planet to mitigate emissions of greenhouse gases (GHG) in the atmosphere. First, it is addressed the Framework Convention to start the discussions on climate changes, then the creation of the Kyoto Protocol, which came, giving nations the opportunity to act, minimizing damage to the environment, thus enabling that developing countries work together through the Clean Development Mechanism (CDM) in creating new and more efficient technologie

Abstract:
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>Composting of pig slurry (DLS) is an important strategy to mitigate the environmental damage of intensive pig farms. Despite being a promising strategy, one of the problems from composting is still the losses of nitrogen (N) by volatilization of ammonia (NH3). Acidification of DLS before to addition to the piles, reducing the pH and thus, the piles, may be a possibility to circumvent this problem. However, little is known about the effect of acidification of DLS, not only on emissions of (NH3) as with respect to emissions of greenh

Ferramentas computacionais, baseadas em modelos de inventários, que consigam predizer, com precisão apropriada, o consumo de combustíveis e as emissões veiculares, principais motivadores do desenvolvimento automotivo atual, são fundamentais para a elaboração de políticas públicas eficazes vinculadas a essas questões. No Brasil, apesar de afetarem significativamente a sociedade, muitas das intervenções governamentais nesse segmento são realizadas sem a adequada avaliação de seus impactos. Isso ocorre ou porque a importância dessas ferramentas nem sempre é reconhecida ou por não se ter ferrament

Abstract:
In this study we determined the magnitude of plant mediated CH4 emission (flux) in two vegetation types of Carex ramenskii. The objectives of this paper were to quantify the proportion of CH4 emissions from plant mediated flux and the total flux (plant and soil). This information is needed in order to understand how grazing affects plant mediated CH4 flux. In addition, we differentiated between two vegetation morphs, grazed and ungrazed, and determined the plant mediated CH4 flux for vegetation type.  This study was conducted at a field site on the Tutakoke River (61 15’N, 165 30’W) which is l

The presented doctoral thesis is focused on environmental impact assessment of basic engineering materials used in a production machine construction. Ecological profile of the machine itself develops already in the phase of its design. It is not only about the choice of future machine parameters and materials that it is built from, but also about technologies used for its manufacture and operation conditions of the finished machine (consumption of energy and service fluids). The thesis occupies in detail with environmental impact analysis of the production machine design from the viewpoint of

L'effetto dei gas serra sul cambiamento climatico ha portato molti esperti a considerare la riduzione delle emissioni di gas serra come strategia per il riscaldamento globale. In particolare tale fenomeno è causato dall’anidride carbonica (CO2), metano (CH4) e il protossido di azoto (N2O). E 'ampiamente accettato che la principale fonte antropica di gas a effetto serra (tranne CO2) è dovuta alle attività agricole. Lo scopo di questo studio è quello di definire concetti e strumenti per facilitare il settore agricolo a ridurre le emissioni di gas serra. In particolare, abbiamo posto la nostra at

Graphite Furnace Atomic Absorption Spectroscopy (GFAA) and Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) are two primary means of analyzing metals at the elemental level. Both techniques are widely accepted as tools for basic research. Each technique is performed differently and has its own distinct advantages as well as disadvantages. The choice of which technique to employ is determined by the needs of the analysis and the limitations of the instrumental technique.The idea to merge the two techniques was originallydeveloped by the research group of Dr. Michael W.
