We develop a new elementary move for simulations of polymer chains in torsion angle space. The method is flexible and easy to implement. Tentative updates are drawn from a (conformation-dependent) Gaussian distribution that favors approximately local deformations of the chain. The degree of bias is controlled by a parameter b. The method is tested on a reduced model protein with 54 amino acids and
Pilosella floribunda (Wimm. and Grab.) Arv-Touv. is reported as new to the provinces Skane and Smaland, southernmost Sweden. There is one recent finding in each of these provinces, in both cases as an established alien on roadsides. Hieracium nemorivagum Jord. ex Boreau, has recently been found at several sites in eastern Skane and at one site in each of the provinces Blekinge and Smaland. This sp
The complexation of sulfate ions at the goethite-water interface has been studied by equilibrium measurements at 298.2 +/- 0.5 K and by infrared spectroscopy. A unified set of data from potentiometric titrations and batch adsorption experiments were evaluated according to an extended Constant Capacitance Model. The obtained equilibrium model consists of two outer-sphere complexes: = FeOH2+, SO42-
Detrital zircon U-Pb SIMS data on quartz-rich metasandstone units presumed to belong to the upper part of the Svecofennian stratigraphy in southeastern Finland and east-central Sweden suggest the existence of clastic sedimentary basins between the two main orogenic phases at 1.89-1.86 Ga and 1.83-1.79 Ga, during a period referred to as the intra-orogenic phase (1.86-1.83 Ga). Stratigraphically bel
Sensitization of guinea pigs by intradermal injections of the occupational allergen trimellitic anhydride (TMA) in oily vehicle has been shown to be very reproducible. We studied the effect of intradermal sensitization with ovalbumin (OA) in oily vehicle on immune and airway responses in guinea pigs. We also compared airway responses to trimellitic anhydride or Dermatophagoides farinae (DF; mite)
We present quantum path distributions of high-order harmonics produced by rare gas atoms interacting with an intense 810 nm laser field, obtained by numerical integration of the time-dependent Schrodinger equation within the single active electron approximation. We find that the distributions are sensitive to the atomic potentials, and differ from the distributions predicted by the strong field ap
Laminar methane/air premixed flames at different pressures in a newly developed high-pressure Bunsen flame rig are studied using detailed numerical simulations and laser diagnostics. In the numerical simulations, one-dimensional and two-dimensional axisymmetric configurations were considered employing detailed transport properties and chemical kinetic mechanisms. In the measurements, OH PLIF was e
Introduction: Lyme borreliosis (LB) is the most common tick transmitted disease in Europe. The diagnosis of LB today is based on the patient´s medical history, clinical presentation and laboratory findings. The laboratory diagnostics are mainly based on antibody detection, but in certain conditions molecular detection by polymerase chain reaction (PCR) may serve as a complement. Aim: The purpose o
Customer demands for fresh salads are increasing, but leafy green vegetables have also been linked to food-borne illness due to pathogens such as Escherichia coli O157:H7. As a safety measure, consumers often wash leafy vegetables in water before consumption. In this study, we analyzed the efficiency of household washing to reduce the bacterial content. Romaine lettuce and ready-to-eat mixed salad
This book is just what we needed to gather the knowledge accumulated on Usher syndrome throughout the past fifteen years. The epidemiology and pathophysiology of the disease are discussed in several chapters. The great importance of an early diagnosis of the disease in affected children in order to provide them with appropriate education and therapeutic choices is suitably emphasized. Present ther
The rd1 (retinal degeneration) mouse retina shows degeneration homologous to a form of retinitis pigmentosa with a rapid loss of rod photoreceptors and deficiency of retinal blood vessels. Due to Pde6brd1 gene mutation, β subunit of phosphodiesterase (PDE) of rd1 retina has an inactive PDE which elevates cGMP and Ca2+ ions level. In vitro retinal explants provide a system close to the in vivo situ
Patientsäkerhetslagen från 2014 säger att patienten ska få sakkunnig och omsorgsfull hälso- och sjukvård som är av god kvalitet och står i överensstämmelse med vetenskap och beprövad erfarenhet. Detta krav är på intet sätt nytt, det har formellt funnits sedan 1890-talet och går att spåra betydligt längre tillbaka i tiden. Formuleringen utgör en klassisk svensk begreppsbildning.Idag hittar vi samma
There has been much interest recently in the relationship between economic conditions and mortality, with some studies showing that mortality is pro-cyclical, while others find the opposite. Some suggest that the aggregation level of analysis (e.g. individual vs. regional) matters. We use both individual and aggregated data on a sample of 20-64 year-old Swedish men from 1993 to 2007. Our results s
