Detectability of life and photosynthesis on exoplanets.

‘Is there life on exoplanets?’. We refer to exoplanets as planets in other solar systems than our own. This often asked question can be further refined by asking ‘is there life on exoplanets which is so extensive that it may impact on its atmosphere, its biosphere and its optical properties?’. And if such a life exists, at astronomical distances from us, can we detect it with instruments on Earth-

Color for the dead, status for the living

Color affects us both consciously and subconsciously, and can create actions and reactions: biological (colorful males to attract females in the animal world), psychological (the use of warm colors or cool colors to effect a specific mood), symbolic (specific colors for weddings and mourning), religious (blue, saffron), emotional (expressionism in art), social (pink and blue infant clothing) or pu

Genetic factors, body constitution, and tumor characteristics in relation to breast cancer prognosis

Prior advancements in research on biomarkers and prognostic host factors have made it increasingly clear that breast cancer is an immensely heterogeneous disease. It remains difficult to predict which patients will benefit from different breast cancer treatments. Hence, interest in personalized medicine is internationally wide-spread and growing. In paper I, we found that tumor detection mode, as

Coffee consumption and the risk of latent autoimmune diabetes in adults-results from a Swedish case-control study

Aims Coffee consumption is associated with a reduced risk of Type2 diabetes. Our aim was to investigate if coffee intake may also reduce the risk of latent autoimmune diabetes in adults, an autoimmune form of diabetes with features of Type2 diabetes. Methods We used data from a population-based case-control study with incident cases of adult onset (35years) diabetes, including 245 cases of latent

Manual correction of semi-automatic three-dimensional echocardiography is needed for right ventricular assessment in adults; validation with cardiac magnetic resonance

Background: Three-dimensional echocardiography (3DE) and semi-automatic right ventricular delineation has been proposed as an appropriate method for right ventricle (RV) evaluation. We aimed to examine how manual correction of semi-automatic delineation influences the accuracy of 3DE for RV volumes and function in a clinical adult setting using cardiac magnetic resonance (CMR) as the reference met

Clinical outcomes from the use of Medication Report when elderly patients are discharged from hospital

Objective The objective of this study was to investigate whether a Medication Report also can reduce the number of patients with clinical outcomes due to medication errors. Method A prospective intervention study with retrospective controls on patients at three departments at Lund University Hospital, Sweden that where transferred to primary care. The intervention group, where patients received a

Surface plasmon resonance for real-time study of lectin-carbohydrate interactions for the differentiation and identification of glycoproteins.

A study of specific interactions between lectins and glycoproteins has been carried out using surface plasmon resonance (SPR) in a flow-injection mode. Lectins were covalently immobilised on the surfaces of the microfluidic sensor chip via amine coupling and serum glycoproteins were injected into the flow channels. Specific lectin-glycoprotein interactions caused the shift of refractive index prop

Reduction in ground vibrations by the use of wave obstacles

The increasing size of the population results in that unbuilt spaces needing to be used for the construction of new facilities. Large construction sites can generate disturbing vibrations to nearby buildings, both while construction is underway and afterwards through the operation of subways, for example. The establishment of new areas close to, for example, motorways and railways increases the ri

Influence of jet-jet interactions on the lift-off length in an optical heavy-duty DI diesel engine

Several investigations have reported that the lift-off length on diesel jets depends strongly on the ambient temperature. The spacing between adjacent jets is thereby expected to influence the lift-off length, as it affects the amount of hot, burned gases present between the jets. Measurements on an 8-hole nozzle in an optical diesel engine showed that the lift-off length can be transient at all t

Fate of Excitations in Conjugated Polymers: Single-Molecule Spectroscopy Reveals Nonemissive "Dark" Regions in MEH-PPV Individual Chains.

Single chains of the conjugated polymer MEH-PPV (poly(2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylenevinylene)) were studied with wide-field fluorescence microscopy (dispersion in inert polymer matrices) and with fluorescence correlation spectroscopy (chloroform solution). The fluorescence yield of individual molecules in matrices was found to be 1-2 orders of magnitude lower than that in solution an

Core-coupled States and Split Proton-neutron Quasiparticle Multiplets in 122-126Ag

Neutron-rich silver isotopes were populated in the fragmentation of a 136Xe beam and the relativistic fission of 238U. The fragments were mass analyzed with the GSI Fragment Separator and subsequently implanted into a passive stopper. Isomeric transitions were detected by 105 high-purity germanium detectors. Eight isomeric states were observed in 122-126Ag nuclei. The level schemes of 122Ag, 123Ag

The layer-by-layer stoichiometry of La0.7Sr0.3MnO3/SrTiO3 thin films and interfaces

By using a combination of synchrotron photoemission and a finite element model, the layer-by-layer stoichiometry of pulsed laser deposited La0.7Sr0.3MnO3 (LSMO) thin films is extracted. For 3- and 5-unit-cell films, the LSMO stoichiometry at the LSMO/SrTiO3 interface has been studied, and it is found that the Sr surface segregation is reversed at the lower interface such that it becomes La rich an

Intraspecific autochthonous and allochthonous resource use by zooplankton in a humic lake during the transitions between winter, summer and fall

Seasonal patterns in assimilation of externally produced, allochthonous, organic matter into aquatic food webs are poorly understood, especially in brown-water lakes. We studied the allochthony (share biomass of terrestrial origin) in cladoceran, calanoid and cyclopoid micro-crustacean zooplankton from late winter to fall during two years in a small humic lake (Sweden). The use of allochthonous re

Substrate porosity induces phenotypic alterations in retinal cells cultured on silicon nanowires

Arrays of silicon nanowires (Si NW) may be used in the development of implantable drug delivery systems. Here, we performed short-and long-term cultures of mouse retinal cells on substrates consisting of high aspect ratio Si NW, which confers high porosity to the surface. As controls, cells were grown on flat silicon substrates. The cell phenotype was assessed using immunocytochemistry, fluorescen

Centrality determination of Pb-Pb collisions at root s(NN)=2.76 TeV with ALICE

This publication describes the methods used to measure the centrality of inelastic Pb-Pb collisions at a center-of-mass energy of 2.76 TeV per colliding nucleon pair with ALICE. The centrality is a key parameter in the study of the properties of QCD matter at extreme temperature and energy density, because it is directly related to the initial overlap region of the colliding nuclei.
