Arthropod predators and detritivores are among the first colonisers on land surfaces undergoing primary succession. In the absence of higher plants and herbivores, they may either have an allochthonous food source (i.e. of geographically distant origin) or local food source that is sustained by e.g. microorganisms. By studying spiders and collembolans on sites along chronosequences on recently eme
Det här avhandlingsprojektet handlar om självmedvetande och hur det förhåller sig till medvetande i stort. Mer specifikt handlar det om jagupplevelse, känslan av att vara ett jag, och om denna känsla med nödvändighet finns med i alla våra upplevelser eller inte. Vad betyder det då att ha en känsla av att vara ett jag? Det kan betyda flera saker, exempelvis känslan av att vara samma person över tidThe present dissertation project concerns the relationship between self and consciousness. Specifically, it concerns the phenomenal sense of self and if this is a necessary component of all experience or not. What is it to have a sense of self? This can refer to several things, such as the sense of being a continuous person through time, the sense of having a body, the sense of being in control of
Frost is damaging to plants when air temperature drops below their tolerance threshold. The set of mechanisms used by cold-tolerant plants to withstand freezing is called “hardening” and typically take place in autumn to protect against winter damage. The recent incorporation of a hardening scheme in the demographic vegetation model FATES opens up the possibility to investigate frost mortality to
With the move to a hydrogen-based primary steel production envisioned for the near future in Europe, existing regional industrial clusters loose major assets. Such a restructuring of industries may result in a new geographical distribution of the steel industry and also to another quality of vertical integration at sites. Both implications could turn out as drivers or barriers to invest in new tec
An effect of permeabilisation and lyophilisation of the yeast cells Hansenula polymorpha on their electrochemical behaviour in the presence of mediators, substrates (formaldehyde, glucose, methanol, ethanol), and cofactors (NAD(+), NADP(+), NADH, NADPH, glutathione) has been studied. Two amperometric techniques differing in the cell immobilisation methods were applied. The cells of a wild strain (
OBJECTIVE: To describe the development of the Systemic Lupus Erythematosus Disease Activity Index 2000 Responder Index-50 (S2K RI-50) Website (www.s2k-ri-50.com) and to assess satisfaction with its training and examination modules among rheumatologists and rheumatology fellows. METHODS: The development of the Website occurred in 3 phases. The first was a deployment phase that consisted of preparin
There is increasing evidence that hepatitis B virus (HBV) infections with different genotypes and subgenotypes differ in response to treatment and long-term prognosis. The differences emerge from variability within the genomes that leads to structural deviations at the pregenomic level and to changes at the translational level. Naturally occurring HBV strains covering the four major genotypes A-D
Familial risks for cancer are important for clinical counseling and understanding cancer etiology. Medically verified data on familial risks have not been available for all types of cancer. The nationwide Swedish Family-Cancer Database includes all Swedes born in 1932 and later (0-to 68-year-old offspring) with their parents, totaling over 10.2 million individuals. Cancer cases were retrieved from
This paper aims to study what influence different meteorological parameters have on the radial tree growth of Scots pine (Pinus sylvestris L.) in peat and mineral soils, as well as to make predictions of radial tree growth responses to changing climate based on various future climate projections. Four Lithuanian peatland complexes representing different geographical settings and hydrological condi
Establishment in flocks by juvenile marsh tits, Parus palustris, was simulated in outdoor aviaries. Encounters between established and intruding juveniles were won by the established ones, irrespective of sex, size or age. As existing flock size increased, establishment became successively harder. Intruding females received less aggression from already established juveniles than did intruding male
The production of 1 ton of PVC requires 2.0 - 2.5 m3 of demineralised water. Some of the water is lost in the process, e.g. as vapor during the drying of the PVC or as sealing water, while approx. 80% of the water could potentially be recycled. In today’s installations only about 20 – 25% of the water recovered by the PVC decanter is used for flushing of the facilities, while 75 – 80% is dischar
Aims: Abdominal aortic aneurysm is a life-threatening condition due to the risk of aneurysm growth and rupture. There are no approved diagnostic or prognostic biomarkers for abdominal aortic aneurysm. We aimed to identify diagnostic and prognostic biomarkers for abdominal aortic aneurysm and to investigate their relationship with abdominal aortic aneurysm diameter and growth. Methods: In this case
Scintillation camera images contain a large amount of Poisson noise. We have investigated whether noise can be removed in whole-body bone scans using convolutional neural networks (CNNs) trained with sets of noisy and noiseless images obtained by Monte Carlo simulation. Methods: Three CNNs were generated using 3 different sets of training images: simulated bone scan images, images of a cylindric p
The present thesis investigates the material scale of six political economiesdistributed across the dry-farming plains and piedmonts of the Middle Bronze AgeJazīrah and the Bilād al-Šām. This is done using a comparative and interdisciplinaryapproach combining the large-scale analysis of administrative cuneiform texts withthe compilation of relevant archaeological survey datasets. Drawing on theori
BACKGROUND: Breast cancer is, despite screening, not always detected early enough and is together with other tumor types known to shed genetic information in circulation. Unlike single-copy nuclear DNA, mitochondrial DNA (mtDNA) copies range from 100s to 10,000s per cell, thus providing a potentially alternative to identify potential missing cancer information in circulation at an early stage.METH
During the Swedish-Russian Tundra Ecology -94 expedition one of the goals was to describe the local population fluctuations of Siberian lemmings over the Eurasian tundra. In order to compensate for the lack of repeated sampling, we used 4 different estimates to determine the phase position of the lemming populations at the different sites: i) the number of lemmings trapped per unit time; ii) the a
Natural radioactivity in the environment is a field gaining more attention in last decades. This work is focused on the study of natural radioactivity complemented with elementary characterization at former non-uraniferous mining areas in Sweden. This aim is addressed through the study of mining lakes, called pit lakes, which are water bodies generated after opencast mining. Environmental matrices
We here suggest and test a new method to obtain stable energies in proteins for charge-neutral reactions by running large quantum mechanical (QM) calculations on structures obtained by combined QM and molecular mechanics (QM/MM) geometry optimisation on several snapshots from molecular dynamics simulations. As a test case, we use a proton transfer between a metal-bound cysteine residue and a secon

Comment on the course evaluation of GEOM10, fall 2022 13 of 14 students answered the course evaluation, which is thus representative. The course was held under this form for the sixth time. Overall the course got an excellent mark of 4.8 on a scale 1-5 (5 = top) (2017: 4.4; 2018: 4.3; 2019: 4.7; 2020: 4.2; 2021: 4.6). We observed an augmentation of satisfaction during the last years as we ongoing
