I en enkätundersökning har biologer, examinerade under åren 1990-1999, besvarat frågor om färdighetsträningen i utbildningen och kompetenskraven i arbetslivet. Denna följdes av en intervjuundersökning med ett strategiskt urval av avnämare på chefspositioner och med personalansvar. Av alumnenkäten framgick att de som var mest nöjda med grundutbildningen i biologi var de som fortsatt till forskarutb

An optimization approach to a multi-dimensional acoustic inverse problem in the time domain is considered. The density and/or the sound speed are reconstructed by minimizing an objective functional. By introducing dual functions and using the Gauss divergence theorem, the gradient of the objective functional is found as an explicit expression. The parameters are then reconstructed by an iterative
We present a formalism which modifies the Mueller Dipole Model such that it incorporates energy-momentum conservation and also important colour suppressed effects. We implement our formalism in a Monte Carlo simulation and compare the results to inclusive data from HERA and the Tevatron, where we see that there is a good agreement between the data and our model.
A 2-y nationwide survey of patients in Denmark with non-tuberculous mycobacteria (NTM) cultures was undertaken. Patients were identified by means of records held at the International Reference Laboratory of Mycobacteriology, Statens Serum Institut, Denmark. The objectives were to identify isolated NTM to species level, to describe the incidence of the various species and to evaluate the clinical s
Translocations t(2;13)(q35;q14) and t(1;13)(p36;q14), which fuse PAX3 and PAX7, respectively, to FOXO1A, characterize alveolar rhabdomyosarcoma. Previous studies have suggested that the expression of PAX7-FOXO1A is copy-number dependent, but that of PAX3-FOXO1A is not, which may be due to a weaker PAX7 than PAX3 promoter. The aim of the present study was to compare the transcriptional activities o
The major cytogenetic subgroup of lipomas is characterized by aberrations of chromosome segment 12q13-15, which recombines with a large number of other chromosomal regions. The gene HMGA2 is the main target in these aberrations. For some recurrent rearrangements, chimeric transcripts, including the 5' part of HMGA2, have been described. The 3' partners identified are LPP, LHFP, CMKOR1, and EBF. In
AIMS: Atrial fibrillation cycle lengths can be assessed from right precordial ECG leads and the unipolar oesophageal ECG using a non-invasive method called Frequency Analysis of Fibrillatory ECG. The purpose of this report is to present the results from application of this method in a large group of patients with long-term atrial fibrillation and to examine the differences between patients with 'c
We study agents situated in partially observable environments, who do not have sufficient resources to create conformant (complete) plans. Instead, they create plans which are conditional and partial, execute or simulate them, and learn from experience to evaluate their quality. Our agents employ an incomplete symbolic deduction system based on Active Logic and Situation Calculus for reasoning abo
The study is based upon material which is a part of the Swedish Agency for Education's evaluation of oral production in year five at primary school. The overall aim of this study is to examine w h a t is assessed by describing the childrens speech, developing and testing criteria for the proficiency in speech in relation to this assessment. For qualitative purposes, a description of the phenomenon
Objective. The effect of repeated contralateral treatment with the kappa-opioid receptor agonist U-50,488H {trans-(+/-)-3,4-dichloro-N-methyl-N-[2-(1-pyrrolidinyl)-cyclohexyl]-ben zene acetamide methanesulphonate} was investigated in rats with unilaterally induced adjuvant arthritis. Methods. Arthritis was induced by injection of Mycobacterium butyricum into the right hindpaw. Inflammatory paramet
Bone mineral density (BMD) measurements are widely used to estimate the risk of osteoporotic fractures. In addition, many other risk factors have been identified, sonic of which are known to add to the risk independently of BMD measurements. The combination of BMD with such risk factors increases the gradient of risk/standard deviation (SD) than that achieved by BMD alone. In this paper, we report
Consider a semigroup of composition operators $T_tf=f\circ \phi_t$, $t\geq 0$, acting on the standard Hardy space $H^p$ $(1\leq p<\infty)$ of the unit disk $D$. Assuming that the $\phi_t$ have a common fixed point at 0, a unique univalent function $h$ can be found such that $h(\phi_t(z))=e^{ct}h(z)$, $z\in D$, $t\geq 0$, where $c$ is a constant which is related to the infinitesimal generator $A$ o
