We report evidence for a robust magnetic compass response in C57BL/6J mice. Mice were trained to build their nests in one of four magnetic directions by creating a light gradient along the long axis of a rectangular cage and positioning a nest box at the opposite (dark) end. The mice were then tested overnight in a circular, visually symmetrical arena in one of four magnetic field alignments. The

Decolonizing the Viking Age 1 argues that the Scandinavian “Viking Age” can be seen as a system of knowledge constructed in the late 19th century and in its basic structures maintained up to the present day. This system of knowledge was heavily influenced by the nationalistic and evolutionary ideas of its time of making and may be described as a colonialism of the past. The book follows the making

The Kaposi's, sarcoma-associated herpesvirus (KSHV) complement control protein (KCP) inhibits the human complement system, and is similar in structure and function to endogenous complement inhibitors. Other inhibitors such as C4d-binding protein and factor H, as well as the viral homologue vaccinia virus complement control protein are known to bind heparin and, for the two latter, also to glycosam

Moraxella catarrhalis IgD-binding protein (MID) is a multimeric outer membrane protein belonging to the family of autotransporters. The IgD-binding domain of MID is located between amino acids MID 962-1200 and binds to amino acids 198-224 of the IgD C(H)1 region. In the present study, we describe a method to purify IgD from serum with high levels of IgD using a two-step affinity chromatography pro

This paper discusses prediction of the subjective response to walking sound - also called drum sound - based on differences in objective measurements. 'Walking sound' refers to the sound heard when someone is walking in the same room as the listener. Walking sound has attracted interest in recent years, particularly due to an increased use of thin floating floor constructions, such as veneer or la

Triad counts for directed graphs are represented as numerators of incomplete U-statistics with symmetric or asymmetric kernels. Asymptotic normality for the simultaneous distribution of all triad counts is proved. Applications are given to investigations of inconsistency in tournaments and reliability of communication networks.

After a long period of stagnation, Syria during the nineteenth century arose to a cultural and social renaissance. One important field of development was education. An article published in Beirut in 1883 sheds important light on this. External impulses were important, but much of the development effort was indigenous. There were significant differences in the level of education between towns and t

The theme of men and women is conspicuous in T. S. Eliot's early poetry. It constitutes the subject of this study, which is an investigation of the symbolic images, metaphors and similes associated with this theme. When a man/woman relationship is referred to, the relevant imagery is often taken from historical or mythical narratives, suggesting an element of universal applicability. Painful feeli

Retinitis pigmentosa (RP) is an inherited blinding disease for which there is no treatment available. It is characterized by a progressive and neurodegenerative loss of photoreceptors but the underlying mechanisms are poorly understood. Excessive activation of the enzyme poly(ADP-ribose) polymerase (PARP) has recently been shown to be involved in several neuropathologies. To investigate the possib

To explore the spatial variation of the soil microbial community within a mixed Norway spruce-birch stand, and to test if the spatial patterns of the microbial community are related to the position of trees, we sampled the forest floor at two spatial scales and used the phospholipid fatty acid (PLFA) patterns as indicators of the microbial community structure. Of the 32 most common PLFAs, 20 (62%)

Using a general 3-D finite-volume code, the development of buoyancy force driven secondary flow and its effects on developing laminar flow and heat transfer have been numerically simulated for a horizontal fuel cell duct with a rectangular cross section. The constant thermal-properties assumption except for linear density variation with temperature in the body force term is applied, and a constant

The use of bio-fuels is becoming more important because of the environmental benefits associated with these fuels. Deactivation of SCR catalysts applied in bio-fuel plants is a major problem due to the high potassium content of bio-fuels and therefore, great potential lies in finding regeneration processes that can be used commercially. Exposing the catalyst surface to sulphate groups generated by

Popular Abstract in Swedish En experimentell och teoretisk studie kring bränder i varulager i både modell och verklig skala har genomförts. Teoretiska modeller för att beräkna flamhöjder, gas temperaturer, gas hastigheter och värmeflöde inuti spalterna mellan de lagrade varorna presenteras. Modellerna kan t ex användas för att beräkna tid till utlösning av olika sprinklers som används för att skydA theoretical and experimental study of rack storage fires and responsiveness of sprinklers is presented. Free-burn tests with non-combustible and combustible material were carried out in reduced scale with verification in large scale. Formulas for in-rack flame height, excess gas temperature, gas velocity and heat flux to storage walls are provided. The formulas include overall heat release rate,

OBJECTIVE: To follow the effect of a 4-month pelvic floor exercise (PFE) program in women with naïve urinary incontinence with vaginal electromyography (EMG), pressure and palpation and also to compare the initial findings with symptom-free women of the same age.METHODS: The pelvic floor function expressed with vaginal EMG, pressure and palpation was measured before, during and after 4 months of P
