The few-picosecond (ps) decay of terahertz (THz) photoconductivity typically observed for conjugated polymer:fullerene blends (at excitation fluencies ∼10(15) photons/cm(2) per pulse) is shown to be a result of charge pair annihilation for two polymer:PCBM blends. At a factor of 100 lower excitation density, the THz decay is in the hundreds of ps time scale, implying that very high carrier mobilit

Since the early 1990s, the European Union (EU) has presented itself as a leader on climate change. Recently, however, this picture has been challenged in the media and by non-governmental organization representatives. The aim of our article is to evaluate the Union's present role in the area of international climate politics. We do this by scrutinizing the EU's own role conception, but also, and p

An experiment was carried out to examine the subjective estimation of fire growth for young adults and their perceived ability to extinguish fires. In the experiment, participants filled out a questionnaire consisting of two parts. The first part involved prediction of fire growth, and the participants were asked to estimate the times between different stages of fires. The second part involved est

The aim of this study was to investigate a combination of satellite images of leaf area index (LAI) with process-based vegetation modeling for the accurate assessment of the carbon balances of Swedish forest ecosystems at the scale of a landscape. Monthly climatologic data were used as inputs in a dynamic vegetation model, the Lund Potsdam Jena-General Ecosystem Simulator. Model estimates of net p

Popular Abstract in English Atherosclerosis is a disease of medium and large sized vessels of our bodies that is mainly characterized by the deposition of lipids in the vessel walls. Increased lipid levels in the blood of an individual, because of lifestyle habits but also because of genetics, can lead to the formation of an “atherosclerotic plaque”. Thus, although lipids are important for the norAtherosclerosis is a chronic inflammatory disease of medium and large vessels of the body which is mainly characterized by the formation of lipid rich plaques within the arterial tissue. It is the most common cause of cardiovascular disease leading to clinical manifestations of coronary artery and cerebrovascular disease. Immune responses targeting modified low density lipoprotein (LDL) play an im

Twelve fossil species of Proteaceous pollen, predominantly attributable to Proteacidites and Beaupreaidites, were recovered from the Maastrichtian-Paleocene sedimentary succession of the Garden Cove Formation on Campbell Island, the southernmost landmass of the Zealandia continent. Among these are two new species, Proteacidites campbellensis and Proteacidites hortisinus. The high diversity of Prot

This article critically studies the hegemonic discursive construction of the EU’s current (2012) economic crisis, as it is articulated by political and economic elites and by mass media. The study focuses on the political economy of the particular crisis and through the critical concept of reification, the study emphasizes the hegemonic naturalization of the economic crisis by the “free market” ec

Charge generation and recombination are studied in blend films of poly-3-hexylthiophene (P3HT) and [6,6']phenyl C61 butyric acid methyl ester (PCBM) using ultrafast transient absorption spectroscopy. We find that the charge generation yield depends upon both blend film composition and thermal annealing. The data suggest that recombination occurs over a wide range of time scales and that, in the le

The ATLAS Transition Radiation Tracker (TRT) is the outermost of the three sub-systems of the ATLAS Inner Detector at the Large Hadron Collider at CERN. It consists of close to 300,000 thin-wall drift- tubes (straws) providing on average 30 two-dimensional space points for charged particle tracks. The straws have 0.13 mm resolution and measure tracks with vertical bar eta vertical bar < 2 and p(T)

Oxidative stress is emerging as a key factor underpinning life history and the expression of sexually selected traits. Resolving the role of oxidative stress in life history and sexual selection requires a pluralistic approach, which investigates how age affects the relationship between oxidative status (i.e., antioxidants and oxidative damage) and the multiple traits contributing to variation in

The flow characteristics and heat transfer are studied in a vertical annulus of a heated cylinder surrounded by a permeable cylinder, subject to cross uniform wind with open end to the environment and in the presence of natural convection. The objective here is to develop a computationally efficient model capable of capturing the physics of the flow and heat transport to predict air renewal rates

While many laboratory studies have focused on the short term effects of biochar addition to soil), there have been comparatively few tracing its longer term effects in the field. This study investigated the multiyear impact of biochar on crop performance and soil quality with specific emphasis on carbon (C) and nitrogen (N) cycling over a 3 y period. Biochar was added to an agricultural field at 0

CONTEXT: Mutations in the low-density lipoprotein receptor-related protein 5 (LRP5) gene cause rare syndromes characterized by altered bone mineral density (BMD). More common LRP5 variants may affect osteoporosis risk in the general population.OBJECTIVE: To generate large-scale evidence on whether 2 common variants of LRP5 (Val667Met, Ala1330Val) and 1 variant of LRP6 (Ile1062Val) are associated w

Technical infrastructures of the society are becoming more and more interconnected and interdependent, i.e. the function of an infrastructure influences the function of other infrastructures. Disturbances in one infrastructure therefore often traverse to other dependent infrastructures and possibly even back to the infrastructure where the failure originated. It is becoming increasingly important
