Factors influencing uptake and levels of persistent pollutants (PCBs, p,p'-DDE) were investigated in 341 northern pike from 61 lakes in southern Scandinavia. Although the inflow of pollutants from the atmosphere was similar throughout the area studied, large differences in levels of PCBs and DDE in predatory fish were found between lakes. The factors primarily responsible for this variation appear
Abstract in FrenchCet article a pour cadre le développement de l'idée du mariage comme une union personnelle se fondant sur la relation entre les époux. Les théories qui se sont développées à partis du XIe siècle à l'intérieur de l'église ont mis l'accent sur le caractère personnel du mariage: le fondement du sacrement du mariage étant devenu l'union entre deux individus et non pas l'interêt familIn this article I examine the development of the idea of marriage as a personal union whose foundation is the relation between the spouses. The theories which developed within the Church from the eleventh century and onwards put the emphasis on the personal side of marriage; the sacrament of marriage was founded on the union between the spouses and not on family interest. From the middle of the tw
We report on optically induced charge storage effects and cur-rent generation in self-assembled InAs quantum dots embedded in an InP matrix. Illumination with photons of energy higher than about 0.86 eV efficiently loads the dots with a maximum of about 1 hole/dot. The spectral response at lower photon energy is strongly enhanced at elevated temperatures. We present a detailed balance model for th
Hur vi ser på teknik hänger ihop med hur vi ser på människan. Forskningen inom området Äldre och design i Lund har en uttalad avsikt: att människor med funktionsnedsättningar ska få bättre förutsättningar. Arbetet börjar och slutar i människan. Seniorer på egna villkor, Bodil Jönsson Design för funktion, Bodil Jönsson Titta på tv – ett sätt att kommunicera, Britt Östlund Design för den mänskli
A new beam line for generating a sub-micron beam spot for high-resolution nuclear microprobe applications has been constructed at the Lund Nuclear Microprobe facility. The design and construction of the beam line, the quality test of the four high precision Oxford OM-52 Quadrupole magnets by the grid shadow method and the beam scanning system are presented in this paper. The beam line is designed
Information on soil mineralogy is essential for weathering rate calculations. Quantitative mineralogical analyses are expensive and time-consuming, and thus indirect methods of determining the mineralogical composition are important, for example estimating the composition based on the elemental content in till (total concentrations), or based on information about the underlying bedrock. The minera
BACKGROUND: Deep sternal wound infection is a serious and potentially lethal complication of cardiac surgery when performed through a median sternotomy. We describe the outcome of a new treatment strategy with C-reactive protein level-guided vacuum-assisted closure used at our department. METHODS: Data from 16 consecutive adult patients who had deep sternal wound infections after cardiac surgery w
A GaAs-based resonant tunneling permeable base transistor has been developed and evaluated at room temperature. The transistor is fabricated by overgrowing a tungsten gate placed next to an AlGaAs-GaAs-InGaAs resonant tunneling heterostructure. By changing the gate voltage, the effective conducting area of the tunnel diode can be modulated and the collector-emitter current thus controlled. Peak cu
The paper describes a project aiming at the construction of functional mimics of the oxygen evolving complex of Photosystem II, coupled to photoinduced charge separation. Biomimetic electron donors - manganese complexes and tyrosine - have been linked to a Ru(II)-polypyridine photosensitizer. Oxidation of the donors by intramolecular electron transfer from the photo-oxidized Ru(III) complex was de
Two different flexible osmium functionalised polymers were investigated for their ability to efficiently "wire" pyranose oxidase when immobilised on graphite electrodes. The two Os-polymers differ in redox potential and the length of the side chains, where the Os2+/3+-functionalities are located. The performance of the redox polymers as mediators for the enzyme was tested with glucose. As well as
BACKGROUND: The acquisition of drug resistance is a major reason for poor outcome of neuroblastoma. Protein kinase C (PKC) has been suggested to influence drug resistance in cancer cells. The aim of this study was to elucidate whether inhibition of PKCbeta isoforms influences drug-resistance of neuroblastoma cells. METHODS: The effect of the PKCbeta inhibitor LY379196 on the growth-suppressing eff
Repeated resistivity measurement is a potentially powerful method for monitoring development of internal erosion and anomalous seepage in earth embankment dams. This study is part of a project to improve current longterm monitoring routines and data interpretation and increasing the understanding when interpreting existing data. This is accomplished by modeling various occurrences typical of emban
This paper addresses a problem for theories of epistemic democracy. In a decision on a complex issue which can be decomposed into several parts, a collective can use different voting procedures: Either its members vote on each sub-question and the answers that gain majority support are used as premises for the conclusion on the main issue (premise based-procedure, pbp), or the vote is conducted on
