Stability of the Camassa-Holm solitons

We consider the stability problem of the solitary wave solutions of a completely integrable equation that arises as a model for the unidirectional propagation of shallow water waves. We prove that the solitary waves possess the spectral properties of solitons and that their shapes are stable under small disturbances.

From distance towards proximity - fathers’ lived experience of caring for their preterm infants

Open interviews with 13 fathers were performed, using a hermeneutic phenomenological method, to illuminate their lived experience of caring for their preterm infant. Their lived experience was expressed as a process moving from initial feelings of distance toward feelings of proximity. The process was described as a pendulum that was easily disturbed. Feelings of distance included experiences of l

Clinical physiology: a successful academic and clinical discipline is threatened in Sweden.

Clinical physiologists in Sweden are physicians (the majority with a PhD degree) with thorough training in system physiology and pathophysiology. They investigate patients in a functional approach and are engaged in basic and applied physiology teaching and research. In 1954, clinical physiology was founded as an independent academic and clinical discipline by the Swedish government to ensure "con

Enhancing Accessibility in Mobile Navigational Services

Abstract in UndeterminedThe success of the Wii and of the iPhone together with the persisting problem of displaying information on the small screens of mobile devices is currently pushing the development of non-visual interaction channels such as gestures, tactile/haptic interaction and sound. This development presents both potential and risk, since new channels of interaction may result either in

Plant uptake of major and minor mineral elements as influenced by soil acidity and liming

This study reports effects on soil solution chemistry and plant uptake of 55 elements (Ag, Al, As, B, Ba, Be, Bi, Br, Ca, Cd, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Fe, Gd, Ge, Hf, Hg, Ho, K, La, Li, Lu, Mg, Mn, Mo, Na, Nb, Nd, Ni, P, Pb, Pr, Rb, S, Sb, Sc, Se, Si, Sm, Sr, Tb, Th, Tl, U, V, W, Y, Yb, Zn, Zr) by raising the pH using addition of fine-grained precipitated calcium carbonate at 20 rates (yiel

Data dependent endogeneity correction in cointegrated panels

This paper examines the small-sample performance of several information based criteria that can be employed to facilitate data dependent endogeneity correction in estimation of cointegrated panel regressions. The Monte Carlo evidence suggests that the criteria generally perform well but that there are differences of practical importance. In particular, the evidence suggests that, although the esti

Cerebral uptake of morphine in the pig calculated from arterio-venous plasma concentration gradients: an alternative to tissue microdialysis

The aim of this study was to characterize the reversible cerebral uptake of morphine in the pig by measuring the changing arterio-venous plasma concentration gradient over the brain. Seven pigs were anaesthetized by continuous infusions of ketamine and pancuronium and ventilated with oxygen in nitrous oxide. During and after 5-min intravenous infusions of morphine hydrochloride, blood samples were

Contact allergy to isoeugenol and its derivatives: problems with allergen substitution

A total of 2261 (808 male, 1453 female) consecutive patients attending contact dermatitis clinics were patch tested to isoeugenol and its derivatives listed in the EU Inventory of Fragrance Ingredients. Positive reactions were found to isoeugenol in 40, transisoeugenol in 40, isoeugenyl acetate in 19, isoeugenyl benzoate in 4, isoeugenyl phenylacetate in 16, isoeugenyl methyl ether in 6 and benzyl

On rotational water waves with surface tension

The purpose of this paper is to present some recent advances in the study of water waves with vorticity and surface tension. These are periodic, two-dimensional waves over a flat bottom and the surface profiles are symmetric and monotone between crest and trough. The proofs rely on bifurcation theory.

Common variants in MODY genes increase the risk of gestational diabetes mellitus.

Aims/hypothesis Impaired beta cell function is the hallmark of gestational diabetes mellitus (GDM) and MODY. In addition, women with MODY gene mutations often present with GDM, but it is not known whether common variants in MODY genes contribute to GDM. Subjects and methods We genotyped five common variants in the glucokinase (GCK, commonly known as MODY2), hepatocyte nuclear factor 1-α (HNF1A, co

Crohn's disease associated CARD15 (NOD2) variants are not involved in the susceptibility to type 1 diabetes

Three variants in the caspase recruitment domain 15/nucleotide-binding oligomerization domain 2 (CARD15/NOD2) gene have been shown to be associated with Crohn's disease (CD). There is a strong support for shared genetic determinants between various autoimmune and inflammatory diseases. In particular, linkage of type 1 diabetes (T1D) and other autoimmune and inflammatory diseases has been reported

Performance of three-phase three-dimensional electrode reactor for the reduction of COD in simulated wastewater-containing phenol

The removal of chemical oxygen demand (COD) from wastewater-containing phenol was investigated using three-phase three-dimensional electrode reactor. Special attention was paid to experimentally probe the performance of the reactor in COD removal in the process of repeated batch runs. The experimental results showed that the reactor could remove COD from phenol-containing wastewater much more effi

Use of inclinometers for measuring postures and movements in order to predict muscle activity

In order to get to know the loads on bone and other tissues there is a need to measure motion. So far, the best way of measuring human locomotion is done in a gait laboratory. But since the equipment is quite expensive and it isn’t mobile, it cannot be used for measuring on people during their daily activities. There is a great interest of finding easier ways to capture the motion in daily situat

Proteomics Data Collection-5th ProDaC Workshop

The Proteomics Data Collection (ProDaC) consortium, a "Coordination Action" funded by the 6th EU Framework Programme, started in October 2006. Its aim was to facilitate the collection and distribution of proteomics data and the public availability of data sets from proteomics experiments. Within the consortium standard formats are created and tools are developed to allow extensive data collection

Mechanisms of leukotriene B-4-triggered monocyte adhesion

Objective - Leukotriene B-4 (LTB4) has been implicated in the trafficking of monocytes to inflammatory pathologicconditions, such as transplant rejection and atherosclerosis. The aim of this study was to determine the mechanisms by which LTB4 contributes to monocyte capture from the circulation. Methods and Results - In in vitro and in vivo vascular models, the lipid chemoattractant LTB4 was an eq

Spline-Galerkin methods applied to Rydberg series between the 4s 2S and 3d 2D limits of calcium

The recently introduced nonvariational spline-Galerkin method [T. Brage and C. Froese Fischer, Phys. Scr. 49, 651 (1994)] for Rydberg series is applied to the J = 0, 1, 2, and 3 even states between the two first limits in neutral calcium. Energies for 3dnl levels up to n = 15-20 are reported and the position of different perturbers belonging to the 4 p2 and 4p 5p configurations are investigated. T

Stem cells: hype or hope?

Stem cells undergo self-renewal and differentiate into multiple lineages of mature cells. The identification of stem cells in diverse adult tissues and the findings that human embryonic stem cells can be proliferated and differentiated has kindled the imagination of both scientists and the public regarding future stem cell technology. These cells could constitute an unlimited supply of diverse cel

Arthritogenic dsRNA is present in synovial fluid from rheumatoid arthritis patients with an erosive disease course

Viruses may be part of the pathogenesis of rheumatoid arthritis (RA). Double stranded RNA (dsRNA) is a prototypic viral conformation of nucleic acid that is highly arthritogenic in mice. Therefore, we developed an ELISA to detect dsRNA in sera and synovial fluids (SF) in RA patients and in osteoarthritic controls. The developed ELISA recognizes picogram levels of viral or synthetic dsRNA but shows
