The exact elastodynamic scattering theory is constructed to describe the spectral properties of two- and more- cylindrical cavity systems, and compared to an elastodynamic generalization of the semi-classical Gutzwiller unstable periodic orbits formulas. In contrast to quantum mechanics, complex periodic orbits associated with the surface Rayleigh waves dominate the low-frequency spectrum, and alr

Nuclear spin relaxation by intermolecular dipole–dipole interactions between macromolecular and solvent nuclear moments forms the basis of a widely used method for investigating macromolecular solvation. In particular, intermolecular cross-relaxation [or nuclear Overhauser effect (NOE)] between protein and water protons has been used to probe the mobility of water molecules interacting with the pr

Background-Myocardial scarring from infarction or nonischemic fibrosis forms arrhythmogenic substrate. The Selvester QRS score has been extensively validated for estimating myocardial infarction scar size in the absence of ECG confounders. but has not been tested to quantify scar in patients with hypertrophy, bundle branch/fascicular blocks, or nonischemic cardiomyopathy. We assessed the hypothese

Bacterial endotoxins (BEs) are integrated part of Escherichia coli, a microorganism widely used for the production of recombinant proteins. BEs should be eliminated in the course of down stream processing of target protein produced by these bacteria. Supermacroporous monolith (continuous bed) columns, so called cryogel columns, with immobilized polyethyleneimine (PEI), polymyxin B (PMB) and lysozy

It is widely recognized that there is a discrepancy between principle and practice with respect to the health equity aim of public policy. This discrepancy is analyzed from two theoretical perspectives: the individualization of society and the fact that individual beliefs and values are connected to one’s position in the social structure. These mechanisms influence both the choice of health policy

An acceleration in the rate at which new aquaporin structures are determined means that structural models are now available for mammalian AQP0, AQP1, AQP2 and AQP4, bacterial GlpF, AqpM and AQPZ, and the plant SoPIP2;1. With an apparent consensus emerging concerning the mechanism of selective water transport and proton extrusion, emphasis has shifted towards the issues of substrate selectivity and

We present a formalism which modifies the Mueller Dipole Model such that it incorporates energy-momentum conservation as well as important colour suppressed effects in the cascade evolution. The formalism is implemented in a Monte Carlo simulation program, and the results are compared to inclusive data from HERA and the Tevatron. We here find a generally very good agreement between our model and t

This is an exploratory study of the use of wh-questions in Swedish children with typical and impaired language development. Swedish is a verb-second (V2) language where inverted word order is not unique to wh-questions, but occurs in all utterances that begin with a constituent other than the subject. The purpose was to investigate types and frequency patterns in the use of wh-questions, wh-word a

Accurate assessment of human intake of mutagenic/carcinogenic heterocyclic ainines (HAs) is necessary for epidemiological studies and future risk assessment. Using questionnaires, the frequency of consumption of specific dishes can be obtained at an individual level and linked to analyzed concentrations of different compounds in corresponding dishes. Some typical Swedish cooked meat dishes, hambur

Degradation of bovine nasal cartilage induced by interleukin-1 (IL-1) was used to study catabolic events in the tissue over 16 days. Culture medium was fractionated by two-dimensional electrophoresis (isoelectric focusing and SDS-PAGE). Identification of components by peptide mass fingerprinting revealed released fragments representing the NC4 domain of the type IX collagen {alpha}1 chain at days

Processing of the recycling proteoglycan glypican-1 involves the release of its heparan sulfate chains by copper ion- and nitric oxide-catalyzed ascorbate-triggered autodegradation. The Alzheimer disease amyloid precursor protein (APP) and its paralogue, the amyloid precursor-like protein 2 (APLP2), contain copper ion-, zinc ion-, and heparan sulfate-binding domains. We have investigated the possi

Radioiodine therapy is a common form for treatment of hyperthyroidism. This treatment has been performed for half a century, with the annual number of I-131-iodide therapies for hyperthyroidism in Sweden being around 3000 since the 1970s. Methods used to calculate the administered activity to the individual patient differ widely, and a survey was made to get information about the different protoco

Infants gradually learn to predict the motion of moving targets and change from a strategy that mainly depends on saccades to one that depends on anticipatory control of smooth pursuit. A model is described that combines three types of mechanisms for gaze control that develops in a way similar to infants. Initially, gaze control is purely reactive, but as the anticipatory models become more accura

Nanotechnology has provided methods to fabricate surface patterns with features down to a few rim. If cells or cell processes exhibit contact guidance in response to such small patterns is an interesting question and could be pertinent for many applications. In the present study we investigated if axonal outgrowth was affected by nano-printed patterns in polymethylmethacrylate (PMMA)-covered silic

Monitoring low molecular weight heparins (LMWH's) in the perioperative period is prudent in patients at high risk of coagulative complications, especially when the patient has an epidural catheter requiring withdrawal, which is associated with the risk of spinal haematoma. The aim of this study was to evaluate the in vitro dose-responses of two different LMWH's on two different viscoelastic haemos

A study of W(+/-)Z production in proton-proton collisions at root s = 7 TeV is presented using data corresponding to an integrated luminosity of 4.6 fb(-1) collected with the ATLAS detector at the Large Hadron Collider in 2011. In total, 317 candidates, with a background expectation of 68 +/- 10 events, are observed in double-leptonic decay final states with electrons, muons and missing transverse

The recent dramatic decline in farmland biodiversity is often attributed to agricultural intensification and structural changes in the agricultural landscape. One suggested farm practice seen to benefit biodiversity and reverse declines is organic farming. Because organic farming is viewed as a more sustainable form of agriculture it is currently subsidized by European agri-environment schemes. Ho
