We have analyzed decade-long methane flux data set from a boreal fen, Siikaneva, together with data on environmental parameters and carbon dioxide exchange. The methane flux showed seasonal cycle but no systematic diel cycle. The highest fluxes were observed in July–August with average value of 73 nmol m−2 s−1. Wintertime fluxes were small but positive, with January–March average of 6.7 nmol m−2 s
Aim: To determine the importance of different biogeographical processes (vicariance, dispersal, long-distance dispersal and establishment or LDDE) for the current distribution of metalmark moths, a group of small insects, using a time-calibrated molecular tree. Location: Global. Methods: We sampled 104 species of metalmark moths with representatives from all six major biogeographical regions of th
Background: Poly-3-d-hydroxybutyrate (PHB) that is a promising precursor for bioplastic with similar physical properties as polypropylene, is naturally produced by several bacterial species. The bacterial pathway is comprised of the three enzymes β-ketothiolase, acetoacetyl-CoA reductase (AAR) and PHB synthase, which all together convert acetyl-CoA into PHB. Heterologous expression of the pathway
The German federal state of North Rhine-Westphalia (NRW) is home to one of the most important industrial regions in Europe, and is the first German state to have adopted its own Climate Protection Law (CPL). This paper describes the long-term (up to 2050) mitigation scenarios for NRW's main energy-intensive industrial sub-sectors which served to support the implementation of the CPL. It also descr
BACKGROUND: The discriminative power of 48-h wireless esophageal pH monitoring in the diagnosis of gastroesophageal reflux disease has not been clearly demonstrated, and the cutoff level for esophageal acid exposure generating the optimal sensitivity and specificity is unknown. SUBJECTS AND Patients with typical reflux symptoms and a distinct response to acid suppressive medication METHODS: underw
Starch granules are an interesting stabilizer candidate for food-grade Pickering emulsions. The stabilizing capacity of seven different intact starch granules for making oil-in-water emulsions has been the topic of this screening study. The starches were from quinoa; rice; maize; waxy varieties of rice, maize, and barley; and high-amylose maize. The starches were studied in their native state, hea
Precipitation and air temperature are key drivers of watershed models. Currently there are many open-access gridded precipitation and air temperature datasets at different spatial and temporal resolutions over global or quasi-global scale. Motivated by the scarcity and substantial temporal and spatial gaps in ground measurements in Africa, this study evaluated the performance of three open-access
Decrease of saline lakes, which comprise 44% of all available lake water, is a major concern. It additionally accelerates the desertification process of the region. Thus, various countries have taken different actions in protecting their lake water levels. The aim of this paper is to assess different strategies directed to tackle the decreased lake water levels in Lake Urmia and the Aral Sea, whic
Breast tomosynthesis (BT) is a new X-ray modality that reconstructs the breast volume in many slices instead of, as in mammography, showing a single 2D projection of the breast. The slice thickness is typically 1 mm for clinically used BT-units. In screening the review of breast images with BT takes two to four times longer than the review of mammography images. In an effort to reduce the review t
Syftet med uppsatsen är att undersöka om Feldenkrais-metoden kan vara till hjälp i sångutövande, och hur man kan använda Feldenkrais-metoden i sångundervisning. Jag har valt att använda mig av en kvalitativ undersökning där jag utgått från litteratur, en intervju samt deltagande observation ur ett emiskt/etiskt perspektiv. Som sångare eller utövare av något musikaliskt instrument är det av stor vi
The debate about evidence based practice has been going on for over twenty years in Sweden without any real conclusion. The purpose of this study was with Bourdieu’s theory about culture production and a discourse analytic approach, highlight the arguments in the debate and the beliefs and assumptions about the evidence based practices on which they are based. The aim was also to investigate the r
In project RASTEP (RApid Source TErm Prediction) a computerized tool for real time prediction of source terms at a nuclear power plant is developed. The tool consists of two modules where one is a Bayesian belief network (BBN). A BBN consists of connected nodes and each node has a defined conditional probability table (CPT), which contains the probabilities that a node is in its different states g
Cardiac magnetic resonance (CMR) images are used to investigate the heart for medical and research purposes. By injecting a contrast substance into the patient, myocardial infarctions (heart attacks) can be visualized in CMR image sets consisting of a number of image slices at different levels of the heart. Analysis of these images can detect an infarction, delineate it and estimate its size. This
Populärvetenskaplig sammanfattning Gallring är en viktig del i det moderna skogsbruket. I Sverige har gallring skett i ca 150 år och i början av 1900-talet ökade intresset då pappersmassaindustrin tog fart. Detta ledde till ett ökat intresse för mindre träd och successivt så ökade behovet att utveckla strategier och gallringsmetodiker. I Sverige genomförs gallringar med 10-25 års intervall och manThe aim of this study was to investigate the growth of individual trees and the effects of thinning in a stand of spruce and pine. This was made through tests of regression between a competition index (CI), which depended on distance and diameter of neighbouring trees, and needle mass (NM), compared to basal area growth (BA growth) and dry-weight. The data used in this study was collected over the
BACKGROUND: There is increasing evidence implicating hemoglobin/heme and their scavengers in oxidative stress-mediated pathologies, but information is limited in abdominal aortic aneurysm (AAA).METHODS AND RESULTS: In this case-control study, we assessed heme/heme-related markers in 142 men with AAA and 279 men with a normal aortic diameter consecutively recruited from an ultrasound screening prog
Tumour deposits are a prognostic factor for overall survival and distant metastasis in lymph node-negative colorectal cancer. However, the current TNM staging system does not account for the presence of tumour deposits in lymph node-positive colorectal cancer, or for the presence of multiple deposits. This study aimed to investigate the prognostic effect of tumour deposit count in patients with coBackgroundTumour deposits are a prognostic factor for overall survival and distant metastasis in lymph node-negative colorectal cancer.
