The Arctic marine ecosystem contains multiple elements that present alternative states. The most obvious of which is an Arctic Ocean largely covered by an ice sheet in summer versus one largely devoid of such cover. Ecosystems under pressure typically shift between such alternative states in an abrupt, rather than smooth manner, with the level of forcing required for shifting this status termed th
The main purpose of this research is to provide an agenda for future warehousing research relevant for both academic development and practitioners’ needs. In order to suggest a practically relevant future research agenda, first a comprehensive literature review was performed to identify research areas covered in the literature. Then, 15 warehouse managers and senior consultants were interviewed to
Background: Proteases of human pathogens are becoming increasingly important drug targets, hence it is necessary to understand their substrate specificity and to interpret this knowledge in practically useful ways. New methods are being developed that produce large amounts of cleavage information for individual proteases and some have been applied to extract cleavage rules from data. However, the
We tested whether the presence of plant roots would impair the uptake of ammonium ([Formula: see text]), glycine, and glutamate by microorganisms in a deciduous forest soil exposed to constant or variable moisture in a short-term (24-h) experiment. The uptake of (15)NH4 and dual labeled amino acids by the grass Festuca gigantea L. and soil microorganisms was determined in planted and unplanted soi
This paper analyses global climate politics from the 2007 Bali Roadmap over the 2009 breakdown at COP15 to the following COP meetings with a focus on central issues and tendencies. The analysis is structured by applying the concepts of content and process as empirical and heuristic tools. This is used as the point of departure to analyse the road to Paris, where COP21 is held in 2015 with the stat
To assess how synergies between climate warming and increased concentrations of humic substances ("brownification") will affect rotifer community establishment in spring, we conducted a mesocosm experiment where we combined a 3 degrees C temperature increase with a doubling in water color, changes corresponding to modeled projections for the coming 25-75 yr. We also performed a complementary preda
A dynamic model of forest ecosystems was used to investigate the effects of climate change, atmospheric deposition and harvest intensity on 48 forest sites in Sweden (n = 16) and Switzerland (n = 32). The model was used to investigate the feasibility of deriving critical loads for nitrogen (N) deposition based on changes in plant community composition. The simulations show that climate and atmosph
The structuring of quantitative genetic variation can have a significant impact on the adaptive potential and long-term viability of species in changing landscapes. The present study of the grass Briza media investigated the relationships between patterns of heritable variation in phenotypic characters and descriptors of landscape structure, land-use history and local habitat conditions in a lands
The Republic of Moldova is celebrating 20 years of independence and is still almost completely dependent on energy imports from the Russian federation. Renewable energy is in its infancy despite a climate that is well suited for solar and wind energy with 2,300 sunshine hours per year and measured wind speeds up to 8.5 m/s. Moldova has a history of wine production and wide spread usage of more tha
There has been significant growth in proprietary trading in recent years and it constitutes a major part of the traded volume in the financial markets. I have analyzed differences in the volume and volatility of Standard & Poor’s 500 index, before and after the announcement of the Volcker Rule. I have also looked into how the biggest investment banks have been affected according to their marke
A new optical interferometer for delay stabilization in attosecond pump/probe experiments is constructed, featuring a custom-made hole-drilled recombination mirror and using a co-propagating HeNe laser for the interference. The interferometer is shown to generate an interference pattern of high enough contrast for delay stabilization. The stability of the measured delay is tested with the interfer
This paper examines the standing of private firms in the post-privatization economic reform in China regarding their access to human capital. The cross-sectional dataset used to test the model is extracted from the World Bank 2012 Enterprise Survey. Using a sample of 2848 Chinese firms of diverse ownership types, the paper studies the effect of firm ownership on human capital, and further studies
Happiness is a relatively new discipline within economics. Traditionally, economists have not paid too much attention to it since they considered that both indicators and theoretical assumptions in which this discipline was based were not neither reliable nor useful for policy recommendations. However, especially in the last decade, there has been extensive research which, if not proved, at least
CO2 Catalysis has been studied with Planar Laser Induced Fluorescence (PLIF) in combination with a mass spectrometer for a small, 23 cubic centimeters, cube shaped flow reactor. Both catalysis processes with one and with two catalysts inside the reactor have been carried out and analysed. Some results have been visualised by images showing concentration, given by the PLIF signal, of CO2 inside the
It is generally acknowledged that wetlands and barrier islands can reduce surge and waves. However, while a general qualitative understanding of these interactions is available in the scientific literature, quantification of these interactions is lacking and has previously been based on limited data of relatively poor quality. The overall aim of this study was to improve the understanding of the i
The predicted global warming may affect freshwater systems at several organizational levels, from organism to ecosystem. Specifically, in temperate regions, the projected increase of winter temperatures may have important effects on the over-winter biology of a range of organisms and especially for fish and other ectothermic animals. However, temperature effects on organisms may be directed strong
To evaluate potential long-term effects of climate change and atmospheric nitrogen (N) deposition on subalpine ecosystems, the coupled biogeochemical and vegetation community competition model ForSAFE-Veg was applied to a site at the Loch Vale watershed of Rocky Mountain National Park, Colorado. Changes in climate and N deposition since 1900 resulted in pronounced changes in simulated plant specie
Vehicular communication channels are characterized by a non-stationary time- and frequency-selective fading process due to fast changes in the environment. We characterize the distribution of the envelope of the first delay bin in vehicle-to-vehicle channels by means of its Rician $K$-factor. We analyze the time–frequency variability of this channel parameter using vehicular channel measurements a
Effective human input devices for computer control are very important to quadriplegics and others with severe disabilities. This paper describes a framework for computer control without need for special PC software or drivers. The framework is based on a tongue control system recently developed at Center for Sensory-Motor Interaction (SMI), Aalborg University. The framework provides emulation of a
