Controls on subsurface methane fluxes and shallow gas formation in Baltic Sea sediment (Aarhus Bay, Denmark)

Sabine Flury McGinnis

Shallow gas accumulates in coastal marine sediments when the burial rate of reactive organic matter beneath the sulfate zone is sufficiently high and the methanogenic zone is sufficiently deep. We investigated the controls on methane production and free me ...

Marriage stability, taxation and aggregate labor supply in the U.S. vs. Europe

Serhiy Stepanchuk

Americans work more than Europeans. Using micro-data from the United States and 17 European countries, we document that women are typically the largest contributors to the cross-country differences in work hours. We also show that there is a negative relat ...

Methane oxidation pathways in Lake La Cruz

Corinne Jegge

Even though lakes only occupy a small percentage of Earth's surface, they represent a natural source of methane, contributing substantially to methane emissions and ultimately to global warming. There is extensive evidence that methane emissions from lakes ...

2015

Fluctuations are ubiquitous in nature and are relevant for nearly every ecological process. The main sources of fluctuations in population abundances are demographic and environmental stochasticity, whose effect on local population dynamics, metapopulation ...

EPFL2015

How green or environmentally friendly urban areas are in comparison with rural areas is a topic that has received much attention in recent years. This is understandable because urban areas already emit around 70% of the global greenhouse gases. This percen ...

Sample and population exponents of generalized Taylor's law

Andrea Rinaldo, Andrea Giometto, Amos Maritan

Taylor's law (TL) states that the variance V of a nonnegative random variable is a power function of its mean M; i.e., V = aM(b). TL has been verified extensively in ecology, where it applies to population abundance, physics, and other natural sciences. It ...

Energy Strategy Formation in the Middle East and North Africa Using a Technology-Driven Energy Planning Approach

Ralf Matthias Dyllick-Brenzinger

The constituent countries of the MENA region---defined in this thesis in conformity with the regional definition of the International Energy Agency and encompassing 17 Muslim countries in North Africa, in the Levant, on the Arabian Peninsula, and Iran---ha ...

Integration of explicit supply-demand interactions in airline schedule planning and fleet assignment

Michel Bierlaire, Matteo Salani, Bilge Atasoy

In airline scheduling problems, integrated decision methodologies have aroused intense interest in the last decade. These integrated approaches allow for more efficient solutions due to the simultaneous decision making process. The studied integrated model ...

Inoculum origin and adaptation had no influence on biomethane potential results with different substrates

Christof Holliger, Marc Deront, Nathalie Bachmann

Biomethane potential (BMP) tests are a valuable tool to design different parts of full-scale anaerobic digestion plants. Recent inter-laboratory studies have shown that the results of BMP tests can vary considerably and a comparison of BMP test norm protoc ...

Changes in particle transport as a result of resonant magnetic perturbations in DIII-D

Holger Reimerdes

In this paper, we introduce the first direct perturbed particle transport measurements in resonant magnetic perturbation (RMP) H-mode plasmas. The perturbed particle transport increases as a result of application of RMP deep into the core. In the core, a l ...
