Clonal plants from poor habitats benefit less from morphologically plastic responses to heterogeneity than plants from more productive sites. In addition, physiological integration has been suggested to either increase or decrease the foraging efficiency of clonal plants. We tested the capacity for biomass production and morphological response in two closely related, rhizomatous species from habit
Background: The need for a mobile workforce inevitably means that the length of the total work day (working and traveling time) will increase, but the health effects of commuting have been surprisingly little studied apart from perceived stress and the benefits of physically active commuting. Methods: We used data from two cross-sectional population-based public health surveys performed in 2004 an
Estimates of relevant source area of pollen (RSAP) and relative pollen productivity (PPE) are critical parameters for quantitative reconstructions of past vegetation and land cover. This study provides estimates for PPE relative to Poaceae for ten taxa, characterizing the cultural landscape of south Estonia and the RSAP for 40 lakes with an average radius of approximately 100 m (22-274 m, average
This thesis examines the relationship between financial development and economic growth. By reviewing previous theories and empirical studies about financial development and economic growth and financial development process in China, I assumed that there is a positive relationship between financial development and economic growth in China case. Then I use time series annual data from 1978 to 2009

Populärvetenskaplig sammanfattning: Småvatten i form av dammar och våtmarker har en viktig funktion i både den terrestra och akvatiska miljön. De fungerar till exempel som buffert för näringsämnen från att flöda ut i havet och dem ökar den biologiska mångfalden bland växter och djur. De flesta antropogena småvattnen har sitt ursprung från 1800-talet och 1900-talets början, då näringsrik märgelleraSmall water bodies in the shape of ponds and wetlands have an important function in both the terrestrial and the aquatic environment. They serve as a buffer to prevent rash out-flow of nutrients into the oceans and they maintain biological diversity for plants and animals. Most anthropogenic small waters originated in the 19th century and beginning of 20th century. During this time, good fertilizi
Populärvetenskaplig sammanfattning Spektroskopi handlar om teoretiska modeller och experiment där man observerar ljus som har växelverkat med materia. Spektroskopiska metoder används inom många olika ämnesområden som exempelvis kemi, fysik och biologi. Ett jordnära exempel på tillämpad spektroskopi är människans öga. Reflekterat ljus från olika föremål samlas in av linsen i ögat, avbildas på näthiIn this thesis a novel spectroscopic method consisting of a combination of frequency domain photon migration (FPDM) and gas in scattering media absorption spectroscopy (GASMAS) is developed, for assessment of the mean optical path length and gas absorption in porous media. The system stability is experimentally investigated and measurements are performed on balsa and pine wood to evaluate the rela
This Master Thesis has been performed as a development project for Asko Cylinda AB in Vara, Sweden. The company develops, manufactures and markets conventional tumble dryers among many other products. An important part of a tumble dryer is the filter holder with belonging fuzz filters mounted on the door of tumble dryer’s. The fuzz filter’s objective is to filtrate the hot drying air that pass thr
BACKGROUND: Secondary peritonitis caused by gastrointestinal perforation is associated with significant morbidity and mortality. Effective management includes surgical source control, antibiotic therapy, and intensive resuscitation. The choice between primary abdominal closure (PAC) and vacuum-assisted closure (VAC) in the management of secondary peritonitis remains a subject of debate.METHODS: Th
I denna studie har det huvudsakliga syftet varit att undersöka hur de danska diftongerna i det fonologiska inventariet realiseras fonetiskt. De primära faktorer som har studerats är dels hur öppningsdiftongernas respektive slutningsdiftongernas "bana" ser ut, dels vilken variation det finns beroende på hur diftongen börjar eller slutar, dvs om t.ex [w]-läget kommer att uppnås oberoende a
Riksdagens utbyggnadsmål innebär att det till år 2020 ska vara möjligt att producera 30 TWh el genom vindkraft. Lokaliseringen av vindkraftverk är en mycket viktig del i uppfyllandet av riksdagens utbyggnadsmål. Den kommunala planeringen är ett verktyg för att kunna uppfylla detta mål. Detta samtidigt som kommunen i tillståndsprocessen kan skydda områden, som inte anses vara lämpliga för vindkraft
The film ”We will meet in the blind spot” takes its point of departure from the architecture in and around the Esposizione Universale di Roma (EUR) area in Rome. The EUR was built during the fascist rule and was meant to be the site of the World Exposition in 1942, in addition to being a celebration of the 20-year jubilee for fascism in Italy. The World Exposition in 1942 never took place due to W
The present study highlights microbial assimilation of carbon (glucose) and nitrogen (NH3–N) from wastewater using heterotrophic bioconversion process. Experiments were conducted to study the role of heterotrophic microbes towards removal of carbon and nitrogen at varying initial concentrations of carbon (COD, 533 to 1600 mg/l) and nitrogen (NH3–N, 73 to 249 mg/l) keeping the initial biomass of mi
Understanding land use and land cover (LULC) change through time is an important aspect when attempting to interpret human-environment interactions through time. Palaeoenvironmental techniques have been crucial in bridging this gap by providing information that has been used to estimate climate change, vegetation change, sea level change etc. through time using a variety of proxies. Producing quan
Objectives: Grating-interferometry-based mammography (GIM) might facilitate breast cancer detection, as several research works have demonstrated in a pre-clinical setting, since it is able to provide attenuation, differential phase contrast, and scattering images simultaneously. In order to translate this technique to the clinics, it has to be adapted to cover a large field-of-view within a clinic
Antisera against a variety of substances have been found to produce an identical immunoreaction in the developing olfactory system of a teleost, the three-spined stickleback (Gasterosteus aculeatus). The label is localized in the olfactory placode, the olfactory nerve and those parts of the secondary olfactory tracts which constitute the dorsal descending fascicles and the ventral descending fiber
Designing appropriate control systems for radiant heating and cooling terminals entails an understanding of their dynamic behaviour. This study experimentally investigates the dynamic response of a room with convective and radiant cooling systems. The experiments were performed in a 12.6 m2 large test room outfitted as a single-office room. The main cooling system was radiant ceiling panels which
Atmospheric CO2 concentrations declined markedly about 70,000 years ago, when the Earth's climate descended into the last glaciation. Much of the carbon removed from the atmosphere has been suspected to have entered the deep oceans, but evidence for increased carbon storage remains elusive. Here we use the B/Ca ratios of benthic foraminifera from several sites across the Atlantic Ocean to reconstr
The global environment suffers from utilizing fossil fuels to powering internal combustion engines (ICE), due to the massive amounts of released CO2. Besides the global impact, the local environments experience high concentrations of harmful pollutants such as NOx, CO, soot and particulate matter (PM). The automotive industry is continuously striving to find new solutions to decrease fuel consumpt
Climate change is a major global threat to biodiversity with widespread impacts on ecological communities. Evidence for beneficial impacts on populations is perceived to be stronger and more plentiful than that for negative impacts, but few studies have investigated this apparent disparity, or how ecological factors affect population responses to climatic change. We examined the strength of the re
