The lichen family Teloschistaceae is one of the larger families of lichenized fungi. Currently it includes one very large heterogenous genus, Caloplaca, with some 1000 or more species with a vast variation in morphology, anatomy and chemistry. The rest of the family is split into 1015 smaller genera, each with 20 or fewer species. There is no modern classification of the family based on molecular
In a patient with chest pain and suspected acute coronary syndrome, the electrocardiogram (ECG) is the only readily available diagnostic tool. It is important to maximize its usefulness to detect acute myocardial ischemia that may evolve to myocardial infarction unless the patient is treated expediently with reperfusion therapy. Since diagnostic guidelines have usually included only ST-elevation m
A novel route toward new galiellalactone analogues via a tandem palladium-catalyzed carbonylation and intramolecular Diels-Alder reaction of a dienyne carbonate is presented.
The thermal resistance of a nanoscale point contact to an indium arsenide nanowire was experimentally determined to be two orders of magnitude larger than the theoretical prediction based on the diffuse mismatch model for a welded contact. The discrepancy is attributed mainly to a much smaller phonon transmission coefficient for the weak van der Waals contact than for a welded contact. The experim
A convenient method for the synthesis and isolation of highly reactive formylsilanes by oxidative cleavage of α-silyl glycols is presented. The mild conditions provide an entry to acid- and heat-sensitive members of this theoretically intriguing class of compounds. The utility of the method is demonstrated through the isolation and subsequent diastereoselective derivatization of t-BuMe2- and t-BuP
The large quantity of material of Hieracium sectt. Hieracium, Vulgata, Bifida and Oreadea collected during the recently completed floristic inventory of the northeastern most Swedish province of Norrbotten has been revised. The number of species known from this previously badly under-collected province hereby increased from 27 to 64, and seven species new to science were revealed. A diagnostic key
The evolution of adaptive phenotypic plasticity relies on the presence of cues that enable organisms to adjust their phenotype to match local conditions. Although mostly studied with respect to nonsocial cues, it is also possible that parents transmit information about the environment to their offspring. Such anticipatory parental effects' or adaptive transgenerational plasticity' can have importa
We illustrate how QCD color structure elegantly can be decomposed into orthogonal multiplet bases corresponding to irreducible representations of SU(N-c) with the aid of Wigner 3j and 6j coefficients. We also show how to calculate the relevant 3j and 6j coefficients using multiplet bases and birdtrack techniques and argue that only a relatively small number of Wigner 3j and 6j coefficients are req
The visual conditions for computer work are complex and include several factors that need to be well controlled. These factors include the lighting system, the design of the computer and screen itself, the screens position and orientation within the room, the surface reflectances and colours of the room, and the visualability of the worker.
Lipids are known to play a crucial role both in the normal control of insulin release and in the deterioration of β-cell function, as observed in type 2 diabetes. Despite this established dual role of lipids, little is known about lipid storage and handling in β-cells. Here, we isolated lipid droplets from oleate-incubated INS-1 832/13 cells and characterized the lipid droplet proteome. In a total
Some 30 years ago it was suggested that catalytic reactions that showed a 'compensation' effect were activated through a vibrational resonance between that one vibrational mode of the reactant that led to reaction and a comparable vibration mode of the catalyst system that represented the energy input. The isokinetic effect can be calculated from this model, in some cases within less than 1 % from
Sorption filters based on granular activated carbon, bone meal and iron fines were tested for their efficiency of removing metals from landfill leachate. Removal of Al, As, Ca, Cd, Co, Cr, Cu, Fe, Hg, Mg, Mn, Mo, Ni, Pb, Sr and Zn were studied in a laboratory scale setup. Activated carbon removed more than 90% of Co, Cr, Cu, Fe, Mn and Ni. Ca, Pb, Sr and Zn were removed but less efficiently. Bone
A simple procedure is developed to probe in situ the association between lipid bilayers and colloidal particles. Here, a one-step method is applied to generate giant unilamellar 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) vesicles (GUVs) by application of an alternating electric field directly in the presence of thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) microgels. We demonstrate th
Myocardial perfusion single photon emission computed tomography (MPS) is one of the most widely used diagnostic methods in patients with suspected ischemic heart disease (IHD). Recently, a novel technique based on cadmium-zinc-telluride (CZT) detectors, pinhole collimators, and a stationary gantry was introduced for MPS. The aim of this work was to investigate how patient positioning affects the r
This paper explores different orientations to child-centered social work as conveyed in the training materials and guidelines of Looking After Children and Assessment Framework in Australia. Canada and Sweden. 'Child centered' is shaped by contextual factors and influences social work practices. We found differences in these approaches as needs based and/or rights based and in relation to how each
We present exploratory data analysis methods to assess inversion estimates using examples based on l(2)- and l(1)-regularization. These methods can be used to reveal the presence of systematic errors such as bias and discretization effects, or to validate assumptions made on the statistical model used in the analysis. The methods include bounds on the performance of randomized estimators of a larg
To identify risk factors for Clostridium difficile infection (CDI) in Danish patients consulting general practice with gastrointestinal symptoms, a prospective matched case-control study was performed; cases (N=259) had positive cultures for toxigenic C. difficile and controls (N=455) negative cultures. Data were analysed by conditional logistic regression. In patients aged 2 years (138 cases), ho
