The family Parmeliaceae (Lecanorales, Ascomycota) is possibly the largest, best known and most thoroughly studied lichen family within its order. Despite this fact the relationship between Parmeliaceae and other groups in Lecanorales is still poorly known. The aim of the present study is to contribute to finding the sister group of Parmeliaceae as an aid in future studies on the phylogeny and char
A mathematical model is presented for calculating heat release rate in the Room Corner Test, where lining materials are mounted on both walls and ceiling. The model is based on a thermal theory for concurrent flow flame spread. By using a simple mathematical representation of the heat release rate from the Cone Calorimeter, analytical solutions are arrived at for the velocity and position of the p
OBJECTIVE: To determine the incidence of acute thrombo-embolic occlusion of the superior mesenteric artery (AOSMA) in a population-based study. MATERIAL: All clinical (n=23,446) and forensic (n=7569) autopsies performed in the city of Malmo between 1970 and 1982 (population 264,000-230,000 inhabitants). The autopsy rate was 87%. METHODS: Calculation of the incidence of AOSMA with intestinal gangre
GaAs:Mn nanowires were obtained on GaAs(001) and GaAs(111)B substrates by molecular beam epitaxial growth of (Ga,Mn)As at conditions leading to MnAs phase separation. Their density is proportional to the density of catalyzing MnAs nanoislands, which can be controlled by the Mn flux and/or the substrate temperature. After deposition corresponding to a 200 nm thick (Ga,Mn)As layer the nanowires are
Breeding synchrony is hypothesised to influence the occurrence and frequency of extra-pair fertilisations (EPFs) in birds irrespective of the social mating system. The two proposed hypotheses make opposite predictions. (1) Synchronous breeding leads to a lower frequency of EPFs because males face a trade-off between mate guarding and obtaining additional matings via extra-pair copulations (EPCs) (
With the human genome in a first sequence draft and several other genomes being finished this year, the existing information gap between genomics and proteomics is becoming increasingly evident. The analysis of the proteome is, however, much more complicated because the synthesis and structural requirements of functional proteins are different from the easily handled oligonucleotides for which a f
The aim of the present Study was to make a 16-year follow-up of children of psychosocial risk mothers as concerns emotional/behavioural problems, self-esteem, life events, and academic grades. Forty-three teenagers (index group) and 61 reference teenagers were personally interviewed and asked to answer the Youth Self-report (YSR), the Self-image questionnaire I Think I Am, and a Life Event questio
In this paper, problems related to simulation model documentation and model exchange between users are discussed. Complex simulation models have gained popularity in the environmental field, but require extensive documentation to allow independent implementation. The existence of different simulation platforms puts high demands on the quality of the original documentation. Recent experiences from
This thesis concerns the usage of large pollen databases and their application to mapping and modelling past vegetation. Maps of past taxon distributions are generated and classification techniques are used to compile maps of past woodland types. These visualisations of pollen data have applications in forest ecology and in modelling the impacts of climate change. Maps of the distribution limits o
Plant ecologists have placed increasing emphasis on a functional understanding of vegetation. One way to gain insight into the assemblage of vegetation communities is to investigate plant trait responses to environmental gradients or experimental treatments. We present simulations of responses of suites of traits to treatments differing in soil resources and disturbance intensity, in order to cons
In this study, a tetracycline-regulated lentiviral vector system, based on the tetracycline-dependent transactivator rtTA2S-M2, was developed for controlled expression of glial cell line-derived neurotrophic factor (GDNF) in the rat brain. Expression of the marker gene green fluorescent protein (GFP) and GDNF was tightly regulated in a dose-dependent manner in neural cell lines in vitro. Injection
The aim of this study was to study the relationship between physician-assessed quality of life parameters, i.e., toxicity and physical performance, and patients' self-reports of their quality of life (QoL). QoL was assessed at baseline and before each treatment. using the EORTC QLQ-C30. The WHO performance score (PS) and toxicity were assessed in physician interviews. The correlations between the
We previously identified matrilin-2 (MATN2), the largest member of the novel family of matrilins. These filament-forming adapter proteins expressed in a distinct, but partially overlapping, pattern in all tissues were implicated in the organization of the extracellular matrix. Matrilin-2 functions in a great variety of tissues. Here, we present the genomic organization of the highly conserved mous
A unique [2Fe-2S] cluster (1) with genuinely five-coordinate ferric ions has been synthesized and investigated both structurally and spectroscopically. The crystal structure of 1 as well as (1)H NMR data reveal that 2,6-bis(imidazol-2-yl)pyridine binds to the [2Fe-2S] core as a tridentate capping ligand. DFT calculations showing spin density on all coordinating atoms support this finding. Cluster
AIMS: To investigate the effects of parenteral administration of MgSO4, and glucose, insulin, and potassium (GIK), on the dominant atrial cycle length during chronic atrial fibrillation (CAF). METHODS AND RESULTS: The length of the dominant atrial cycle (DACL) in the power-frequency spectrum of the QRST-suppressed lead V1 ECG was identified before and after intravenous administration of MgSO4 alon
Radiotherapy to the head and neck region leads to severe side effects in the oral cavity but knowledge about severity and onset is scarce among oncology nurses in a radiotherapy department. The aim was to test the Oral Assessment Guide for reliability and validity for patients receiving radiotherapy to the head and neck region. A prospective design with repeated assessments was selected. Thirty-si
Electric Hybrid Vehicles, EHV, are under development to provide lower fuel consumption levels and minimize the environmental pollution compared to pure Internal Combustion Engine, ICE, driven vehicles. The EHV is more complex and thus carry many more extra parts than the pure ICE based vehicle. Competing against the pure ICE vehicle in the sense of nonexpensive mass production is hard. This thesis
We study and solve the previously unstudied problem of finding both sender and receiver positions from time of arrival (TOA) measurements when there is a difference in dimensionality between the affine subspaces spanned by receivers and senders. Anchor-free TOA network calibration has uses both in sound, radio and radio strength applications. Using linear techniques and requiring only a minimal nu
Dumping is generally considered an unfair practice and through the Antidumping Agreement of the GATT many governments offer protection to domestic producers against dumped goods. In 1992 and 1998 large amounts of steel entered the U.S. at low prices, and large amounts of antidumping investigations were initiated in order to curb the surge of imports flooding the country. The increase in steel imp
