Popular Abstract in Swedish Under 9 år (1989-1997) studerades individuellt märkta mindre hackspettar i ett undersökningsområde i södra Smålands ädellövskogar. De flesta studierna gjordes i 17 potentiella revir, vilka undersöktes årligen. Följningar av hackspettar försedda med radiosändare visade att fåglarna rörde sig inom ett, i medeltal, 742 ha stort hemområde under vintern. Under häckningstideOver 9 years, 116 breeding attempts made by individually marked lesser spotted woodpeckers (Dendrocopos minor) were followed in a study area in southern Sweden. The home-range area decreased from on average 742 ha in winter to a defended territory of 103 ha prior to breeding and 43 ha during nesting. The annual timing of the breeding varied between years but was each year synchronized with the bu

Popular Abstract in Swedish Alla celler behöver energi och de skaffar den på olika sätt, t. ex. från oxidering av mat eller från solljus. Adenosin trifosfat (ATP), som kallas för cellens energivaluta, kan dock inte syntetiseras direkt från mat eller ljus. Nästan alla organismer utnyttjar proteinkomplex i form av en andningskedja som sitter i membranet för att alstra en proton potential. Det kan liComplex I is the mitochondrial enzyme complex that oxidizes NADH produced in the citric acid cycle and reduces quinone in the membrane, coupled to proton pumping out of the mitochondrial matrix, creating a membrane potential. This process generates about 40% of the energy used by living organisms. High-resolution structures of complex I recently became available, but the molecular mechanism behind

Technology transfer is important to understand how knowledge is transformed to economic value. Applying a case study approach, this thesis investigates the technology transfer efforts from the University of Dar Es Salaam to indigenous informal SMEs in Tanzania and examines the impact of one of their technology transfer mechanisms on the specific technological capabilities that were acquired at the

This thesis presents two new technologies, SIRE technology based biosensors and magneto immunoassays, which can be used for bioanalytical applications. One of the main problems associated with biosensor technology is the instability of the recognition element since it is of biological origin and thus, has a limited lifetime. Conventionally, this problem has been solved by immobilizing the biologic

We used PCR and DNA sequencing to screen for haemosporidian parasites (Haemoproteus and Plasmodium) in 2,488 individual birds from 104 species and 22 families, primarily understory suboscine passerines, captured in a lowland Amazonian forest in Ecuador as a first major step to understanding the transmission dynamics of this cosmopolitan group of parasites in this region. To assess diversity of avi

Little is known about c-type cytochromosomes in Gram-positive bacteria in contrast to the wealth of information available on this type of cytochrome in Gram-negative bacteria and in eucaryotes. In the present work, the strictly aerobic bacterium Bacillus subtilis was analyzed for subcellular localization and number of different cytochromes c. In vivo labeling with radioactive 5-aminolevulinic acid

Objectives: Dysglycemia and glycemic variability are associated with poor outcomes in critically ill patients. Targeted temperature management alters blood glucose homeostasis. We investigated the association between blood glucose concentrations and glycemic variability and the neurologic outcomes of patients randomized to targeted temperature management at 33°C or 36°C after cardiac arrest. Desig

OBJECTIVE: Identification of the causal mutation in an African-American family with adult-onset primary dystonia. BACKGROUND: The vast majority of patients with dystonia are adults with primary focal or segmental anatomical distributions. Familial and sporadic dystonia appear to share the same genetic etiological background. Although approximately 10% of probands have at least one first- or second

In this paper, we consider positioning with observed-time-difference-of-arrival (OTDOA) for a device deployed in long-term-evolution (LTE) based narrow-band Internet-of-things (NB-IoT) systems. We propose an iterative expectation- maximization based successive interference cancellation (EM-SIC) algorithm to jointly consider estimations of residual frequency- offset (FO), fading-channel taps and ti

microRNAs (miRNAs) are 20-24 nucleotides small, single-stranded, non-coding RNAs. They associate with Argonaute (AGO) proteins and exert their function by inhibition or degradation of messenger RNAs. A single miRNA can target hundreds of genes and one gene can be targeted by several miRNAs, hereby giving rise to a complex post-transcriptional network. In the brain, hundreds of miRNAs are expressed

Aims: Climate change is known to drive both the reshuffling of whole assemblages and range shifts of individual species. Less is known about how local colonizations and extinctions of individual species contribute to changes at the community level. Our aim was to estimate the contribution of individual species to a change in community composition attributed to climate change and to relate these sp

Bacterial genomes typically consist of a single chromosome and, optionally, one or more plasmids. But whole-genome sequencing reveals about ten per-cent of them to be multipartite, with additional replicons which by size and indispensability are considered secondary chromosomes. This raises the questions of how their replication and partition is managed without compromising genome stability and of

Zebrafish is emerging as a complement to mammals in behavioral studies; however, there is a lack of comparative studies with rodents and humans to establish the zebrafish as a predictive translational model. Here we present a detailed phenotype evaluation of zebrafish larvae, measuring 300-3000 variables and analyzing them using multivariate analysis to identify the most important ones for further

Background and Purpose - Acute stroke patients with unknown time of symptom onset are ineligible for thrombolysis. The diffusion-weighted imaging and fluid-attenuated inversion recovery (FLAIR) mismatch is a reasonable predictor of stroke within 4.5 hours of symptom onset, and its clinical usefulness in selecting patients for thrombolysis is currently being investigated. The accuracy of the visual

Background/aim: The role of the microbiome has been widely discussed in the etiology of appendicitis. The primary aim was to evaluate the microbiome in the normal appendix and in appendicitis specifically divided into the three clinically and histopathologically defined grades of inflammation. Secondary aims were to examine whether there were any microbiome differences between proximal and distal

Media Experiences travels across people and popular culture, exploring the pathways to engagement and the various ways in which we shape and are shaped by the media landscapes in which we move. This exploration includes the voices and bodies, sights and sounds of audiences as they experience entertainment through television drama, reality TV, at live events, and within digital television itself, a

Background: With improving survival in ovarian cancer, second primary cancers (SPCs) and their etiological foundations are becoming an issue. The ways in which family history may influence the occurrence of SPCs and the related mortality are not well known. Methods: Based on the Swedish Family-Cancer Database, we identified 11,300 ovarian cancer patients and followed them for diagnoses of SPCs unt

With timely allocated movement phases, mobile organisms can match their space-use with the seasonality of the environment and thereby optimise their resource utilisation over time. Long-distance avian migrants are known to move with the seasonal dynamics on an annual basis, but how individuals respond to seasonality within their tropical non-breeding range has been less studied. Here we analyse th
