This paper develops a new approach in the analysis of the Camassa-Holm equation. By introducing a new set of independent and dependent variables, the equation is transformed into a semilinear system, whose solutions are obtained as fixed points of a contractive transformation. These new variables resolve all singularities due to possible wave breaking. Returning to the original variables, we obtai

Plants of Pinus spp. were grown in observation chambers with the mycorrhizal fungi Suillus bovinus, Pisolithus tinctorius or Paxillus involutus. After interconnecting mycelial systems had developed between plants, individual hosts in some chambers of each species were fed with 14CO2. Mycelia from radioactively labelled and unlabelled chambers were harvested and their carbohydrates were extracted,

Since July 2007, the world economy has experienced a severe financial crisis that originated in the U.S. housing market. Subsequently, the crisis has spread to financial sectors in European and Asian economies and led to a severe worldwide recession. The existing literature on financial crises rarely distinguishes between factors that create the original strain on the financial sector and factors

Rhesus Rhadinovirus (RRV) is currently the closest known, fully sequenced homolog of human Kaposi's sarcoma-associated herpesvirus (KSHV). Both these viruses encode complement inhibitors: KSHV-complement control protein (KCP) and RRV-complement control protein (RCP). Previously we characterized in detail the functional properties of KCP as complement inhibitor. Herein, we performed comparative ana

Health has been a central concept in nursing science since the 18th century but the holistic concept of health that includes both the body and the soul, still has to be clarified. The concept of health is often unclear and represents an unreachable ideal state that can be hard to use as a realistic goal in nursing care. The aim of this study was to describe how the patient perceives the concept of

The objective was to explore the impact on physical health of a lifestyle programme among persons with psychiatric disabilities, and their caregivers. Their satisfaction with the intervention was also assessed. Somatic comorbidity and an increased mortality related to the lifestyle among persons with psychiatric disabilities are well known. Few randomized controlled trials have been aimed specific

This paper compares reasoning surrounding organic food labelling with arguments concerning mandatory GM labelling. Focus is placed on argumentative cross-overs, defined as cases where actors or organizations use a certain type of argumentation for one issue (for example, modes of food production), and shift into using their opponent's type of argumentation for a closely related issue (for example,

A sample of 125 consecutive patients from a Swedish detoxification unit were followed up at five years. Register data on criminal behavior were retrieved for 99% of all subjects, including those who were deceased at follow-up, and 76% of living subjects were interviewed. A diagnosis of antisocial personality disorder (ASPD) at intake was associated with incarceration, continuous drug use, dependen

This study was aimed at investigating the psychometric properties of the Interview Schedule for Social Interaction (ISSI), in terms of construct and discriminant validity and unidimensionality, in three psychiatric samples with varying prerequisites for social interaction: 1) an outpatient sample of working age with mixed diagnoses, 2) an outpatient sample with schizophrenia, and 3) an inpatient s

he present study focused on the functional role of the mutation Ile66Thr located in the N-terminal epidermal growth factor-like domain of coagulation factor IX (FIX). This mutation causes mild hemophilia B with approximately 25% FIX coagulant activity and FIX antigen levels of around 90% of normal. In the 3-dimensional structure of porcine FIXa and in the subsequent 3-dimensional model of human FI

BACKGROUND: Electrophoresis of serum samples allows detection of monoclonal gammopathies indicative of multiple myeloma, Waldenstrom macroglobulinemia, monoclonal gammopathy of undetermined significance, and amyloidosis. Present methods of high-resolution agarose gel electrophoresis (HRAGE) and immunofixation electrophoresis (IFE) are manual and labor-intensive. Capillary zone electrophoresis (CZE

BACKGROUND: It is important to clarify the biological function of the female sex hormones estrogen and progesterone in periodontal ligament cells, as these hormones may affect periodontal health. We have previously shown that human periodontal ligament cells express estrogen receptor beta (ERbeta) but not ERalpha, whereas human breast cancer cells (MCF7) express both ERalpha and ERbeta. Data on pr

The northern pike (Esox lucius) is an important and selective piscivore that chooses smaller prey than predicted from energy / time budgets. In a laboratory experiment, we investigated pike predatory behavior to explain this selectivity. Northern pike feeding on different prey sizes in aquaria were observed when foraging alone, when in the presence of chemical cues from similar-sized or larger con

The degradation of extracellular matrix during cancer invasion results from the action of several protease and protease inhibitor systems. alpha(1)-Antitrypsin (AAT) is a serine proteinase inhibitor produced by various tumour cells, and its plasma concentration rises during inflammation, infection and malignant diseases. AAT is found in a native, inhibitory active form, but also in other, non-inhi

Various techniques are available for the conversion of lignocellulosics to fuel ethanol. During the last decade processes based on enzymatic hydrolysis of cellulose have been investigated more extensively, showing good yield on both hardwood and softwood. The cellulase production of a filamentous fungi, Trichoderma reesei Rut C 30, was examined on carbon sources obtained after steam pretreatment o

BACKGROUND: The purpose of this study was to validate the use of whole-blood samples in the determination of circulating forms of prostate-specific antigen (PSA). METHODS: Blood samples of hospitalized prostate cancer and benign prostatic hyperplasia patients were collected and processed to generate whole-blood and serum samples. Three different rapid two-site immunoassays were developed to measur
