Plants can influence methane emissions from wetland ecosystems by altering its production, consumption and transport in the soil. The aim of this study was to investigate how eight vascular plant species from mesotrophic to eutrophic wetlands vary in their influence on CH4 emissions from peat cores, under low and high N supply. Additionally, we measured the production of low-molecular-weight organ

In order to understand exciton migration and fluorescence intensity fluctuation mechanisms in conjugated polymer single molecules, we studied fluorescence decay dynamics at "on" and "off" fluorescence intensity levels with 20 ps time resolution using MEH-PPV [poly(2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylenevinylene] dispersed in PMMA. Two types of intensity fluctuations were distinguished for sin

The purpose of this doctoral dissertation is to illustrate and explain the connections between the establishment of new cults of Saints and the formation of an ecclesiastical organization in Scandinavia. Its main conclusion is that "the creation of new cults of native saints was not necessary for the establishment of ecclesiastical institutions" (p. 255), but that such cults in many cases helped g

Bioavailable phosphorus (BAP) concentrations were determined nine times between April and October 2010 in two humic boreal headwater streams draining forest-and mire-dominated catchments. BAP was analyzed in a bioassay in which natural P-limited bacterioplankton grew with natural P as the sole P source. In both streams, approximately 90% of the BAP occurred as dissolved species (passing a 0.2-mu m

The radioactive isotope In-107 was studied using sub-barrier Coulomb excitation at the REX-ISOLDE facility at CERN. Two gamma rays were observed during the experiment, corresponding to the low-lying 11/2(+) and 3/2(-)states. The reduced transition probability of the 11/2(+) state was determined with the semiclassical Coulomb excitation code GOSIA2. The result is discussed in comparison to large-sc

In this paper, we survey Faster-than-Nyquist (FTN) signaling, an extension of ordinary linear modulation in which the usual data bearing pulses are simply sent faster, and consequently are no longer orthogonal. Far from a disadvantage, this innovation can transmit up to twice the bits as ordinary modulation at the same bit energy, spectrum, and error rate. The method is directly applicable to orth

Background Clinical classification of rare sequence changes identified in the breast cancer susceptibility genes BRCA1 and BRCA2 is essential for appropriate genetic counselling of individuals carrying these variants. We previously showed that variant BRCA1 c.5096G>A p.Arg1699Gln in the BRCA1 transcriptional transactivation domain demonstrated equivocal results from a series of functional assays,

Relentless scaling of CMOS fabrication technology has made contemporary integrated circuits increasingly susceptible to transient faults, wearout-related permanent faults, intermittent faults and process variations. Therefore, mechanisms to mitigate the effects of decreased reliability are expected to become essential components of future general­ purpose microprocessors. In this paper, we introdu

Popular Abstract in Swedish Bakgrund Med stigande ålder ökar antalet kroniska sjukdomar hos patienten och därmed även mängden läkemedel. I grunden är läkemedel bra produkter som lindrar, botar eller förebygger sjukdomar och lidande. Dock är äldre (>65 år) mer utsatta för potentiellt negativa effekter av läkemedel. Äldre personer använder många läkemedel, i synnerhet gäller det de äldre som bor påIntroduction: Older patients’ knowledge about their medicines is generally poor. Patients are entitled to be informed on an individual and adequate level. Evidence-based guidelines should, in most cases, be followed also in the treatment of elderly to avoid suboptimal treatment, for example for cardiovascular conditions, or risky prescriptions in the case of renal impairment. Objectives: 1. To de

Metal nanostructures can transfer electromagnetic energy from femtosecond laser pulses to the near-field down to spatial scales well below the optical diffraction limit. By combining few-femtosecond laser pulses with photoemission electron microscopy, we study the dynamics of the induced few-cycle near-field in individual bowtie nanoantennas. We investigate how the dynamics depend on antenna size

Background. The pulmonary donor pool would increase substantially if lungs could be donated after cardiac death (DCD). There have been ethical and legal obstacles since administration of heparin and cooling has to be done immediately after cardiac death. This study examines whether ventilation of DCD lungs without administering heparin or cooling the lungs after cardiac death could improve graft f

Abstract in UndeterminedAn efficient technique is introduced to reduce mutual coupling between two closely spaced PIFAs for MIMO mobile terminals. The proposed mutual coupling reduction method is based on a T-shape slot impedance transformer and can be applied to both single-band and dual-band PIFAs. For the proposed single-band dual PIFAs, the 10 dB impedance bandwidth covers the 2.4 GHz WLAN ban

New robotic applications often require physical interaction between the robot and its environment. To this purpose, external sensors might be needed, as well as a suitable way to specify the tasks. One complication that might cause problems in the task execution is orientation representation singularities. In this paper quaternions are used as a singularity-free orientation representation within t

We show that coherent electron transport through zero-dimensional systems can be used to tailor the shape of the system's transmission function. This quantum-engineering approach can be used to enhance the performance of quantum dots or molecules in thermal-to-electric power conversion. Specifically, we show that electron interference in a two-level system can substantially improve the maximum the
