Spiders in Iceland: distributions, species richness, and faunal changes

Spiders were collected, mostly by pitfall trapping in the 1970s, in a variety of habitats, mainly in lowland areas all around Iceland. Among the 62 species collected five were first records for Iceland (viz. Micaria pulicaria, Robertus lyrifer, Theonoe minutissima, Wabasso replicatus, and Bathyphantes gracilis). Most of the material (comprising ca 18 000 adult spiders) was obtained by pitfall trap

Symptoms, clinical and physiological findings motivating home mechanical ventilation in patients with neuromuscular diseases

Objective: To clarify the relationship between symptoms, clinical signs and physiological abnormalities that were motivating the initiation of home mechanical ventilation in patients suffering from neuromuscular diseases. Methods: From The Swedish Home Mechanical Ventilation Register we identified 352 patients with neuromuscular diseases and we looked at circumstances ( acute vs elective) and clin

Heat transfer augmentation in an oscillating flow

For combustors a heat transfer augmentation of two to five times higher than expected has been reported. Experiments, where the temperature profile in the tail pipe of the pulse combustor has been measured, give no indication why the heat transfer should be augmented. The objective is to study the heat transfer of an oscillating flow between two parallel plates. A set of governing equations is for

Angiotensin converting enzyme (ACE) gene polymorphism in sarcoidosis in relation to associated autoimmune diseases

OBJECTIVES: To investigate the significance of ACE gene insertion/deletion (I/D) polymorphism in the frequency of autoimmune manifestations in sarcoidosis. DESIGN: In patients with sarcoidosis the ACE gene I/D polymorphism was detected with PCR on genomic DNA. The patients with sarcoidosis were divided according to the presence (n = 30) or absence (n = 32) of autoimmune manifestations. The former

Numerical simulations of surface convection in a late M-dwarf

Based on detailed 2D and 3D numerical radiation-hydrodynamics (RHD)simulations of time-dependent compressible convection, we have studiedthe dynamics and thermal structure of the convective surface layers of aprototypical late-type M-dwarf (Teffapprox 2800 K, log g=5.0,solar chemical composition). The RHD models predict stellar granulationqualitatively similar to the familiar solar pattern. Quanti

Low CXCR1 Expression and Susceptibility to Acute Pyelonephritis

Urinary tract infections (UTIs) are clustered in certain individuals but the molecular basis of disease susceptibility is not known. A single gene was shown to control the susceptibility to acute pyelonephritis and renal scarring in mice. The IL-8 receptor homologue (mIL-8Rh) controls neutrophil function during acute infection and the mIL-8Rh deletion causes tissue damage through neutrophil entrap

Nationell ära och manlighet i Karl XII (1925) - en historisk filmanalys

During the 1920s, when the Swedish defence was under heavy debate, military and conservative forces on the right tried to turn the Swedish public opinion towards a climate more in favour of the defence by producing a big budget war film – Karl XII. In several senses the film became a great success. In Sweden the attendance figures were as high as one million (of a population of six) and the film w

Combined magnetic and structural investigation of nano crystalline iron oxides: The interplay between crystal size and phase composition during FeS2 oxidation

The oxides that form during thermal oxidation of natural FeS2 (pyrite and marcasite) consist of nanometer-sized crystals of alpha-Fe2O3 and gamma-Fe2O3. This is shown with heating experiments that were made up to 650 degrees C, which resembles temperatures used in metallurgical processes. It is shown that magnetic measurements can play a key role in the investigation of this reaction, due to the u

Isothermal calorimetry approach to evaluate tissue damage in carrot slices upon thermal processing

The purpose of this investigation was to test calorimetry as a means of quantifying cell damage occurring at various stages of mild blanching treatments. Calorimetric measurements were carried out on cores taken from carrot slices blanched at 100 degreesC for 5-45 s. The calorimetric data were corrected for the influence of wounding stress due to slicing and coring. The validity of calorimetry to

The human antibody repertoire to infectious agents: implications for disease pathogenesis

Antibodies are critical entities used for the protection of an individual organism against infection and disease. Through a complex series of events genes rearrange to encode repertoires of molecules, which are tested for their ability to identify foreign molecules. In this report, we discuss factors defined by the individual as well as by infectious organisms that shape the antibody repertoire. A

Preliminary evaluation of two fluorescence imaging methods for the detection and the delineation of basal cell carcinomas of the skin

Abstract Background and ObjectiveFluorescence techniques can provide powerful noninvasive means for medical diagnosis, based on the detection of either endogenous or exogenous fluorophores. The fluorescence of δ-aminolevulinic acid (ALA)-induced protoporphyrin IX (PpIX) has already shown promise for the diagnosis of tumors. The aim of the study was to investigate the localization of skin tumors a

Occupational risk factors for small bowel carcinoid tumor: A European population-based case-control study

Small bowel carcinoid tumor (SBC) is a rare disease of unknown etiology bill with all age-, sex-, and place-specific occurrence that may indicate an occupational origin. A European multicenter population-based case-control study was conducted from 1995 through 1997. Incident SBC cases between 35 and 69 years of age (n = 101) were identified, together with 3335 controls sampled from the catchment a

How do birds' tails work? Delta-wing theory fails to predict tail shape during flight

Birds appear to use their tails during flight, but until recently the aerodynamic role that tails fulfil was largely unknown. In recent years delta-wing theory, devised to predict the aerodynamics of high-performance aircraft, has been applied to the tails of birds and has been successful in providing a model for the aerodynamics of a birds tail. This theory now provides the conventional explanati
