The morphogenesis of intention and structural stability of motifs.

This article is based on the Agent-action-Objective (AaO) axiom and assumes that intention can be discovered and made evident. But this requirement can be satisfied only under the condition that a particular individual can be identified with his style of writing. This implies that the nature of writing becomes approachable. Getting a style under control presupposes the A-component, which is discus

Ultramicrobiosensor for the selective detection of glutamate

Carbon fiber microelectrodes, able to detect catecholamine release from single cells, have significantly contributed to our present understanding of the mechanism of secretory neurotransmission. In spite of their obvious advantages, there are only a few amperometric sensors (characterized by appropriate size, sensitivity, and selectivity) able to measure the release of other (not easily oxidizable

Statistics for chemistry students - how to make a statistics course useful by focusing on applications

By putting emphasis on applications in two basic statistics courses for chemistry students and chemical engineering students we have enhanced student motivation and increased student activity. In addition to a traditional in-class exam, the students complete a take-home project where statistical problems relevant to chemists are discussed. We give several examples of the course and project materia

Renal angioplasty causes a rapid transient increase in inflammatory biornarkers, but reduced levels of interleukin-6 and endothelin-1 1 month after intervention

Objective To examine prospectively whether inflammatory biomarkers and endothelin (ET)-1 are increased in patients with renal artery stenosis (RAS), and to investigate how treatment with percutaneous transluminal renal angioplasty (PTRA) affects these variables during the first month after intervention. Methods One hundred patients with suspected RAS undergoing renal angiography were included. PTR

Subjective versus interviewer assessment of global quality of life among persons with schizophrenia living in the community: A Nordic multicentre study

Background: Few studies have investigated differences between subjective and externally assessed quality of life in individuals with a severe mental illness. In a sample of 387 patients with schizophrenia living in the community the present study investigated the association between subjective and interviewer-rated quality of life, clinical and sociodemographic factors related to the two assessmen

A novel electrical property of three-terminal ballistic junctions and its applications in nanoelectronics

A room-temperature electrical property of three-terminal ballistic junctions (TBJs) is predicted. For a symmetric TBJ. it is shown that when finite voltages F and -V are applied to the left and right branches. the voltage Output V, from the central branch will always be negative. This characteristic appears even when the symmetry in the TBJ is broken. provided that V! is larger than a threshold. A

Preparation of YBa2Cu3O6 + x by a Formic Acid Method

Synthesis of YBa2Cu3O6+x from formic acid solutions of stoichiometric amounts of the initial materials has been investigated in the temperature range 750–950°C. The reaction is strongly influenced by the concentration of formic acid. Dilute solutions favor synthesis of purer samples under moderate conditions of temperature and sintering time. At lower temperature the same effect can be achieved if

The potential of proton beam radiation therapy in intracranial and ocular tumours

A group of oncologists and hospital physicists have estimated the number of patients in Sweden suitable for proton beam therapy. The estimations have been based on current statistics of tumour incidence, number of patients potentially eligible for radiation treatment, scientific support from clinical trials and model dose planning studies and knowledge of the doseresponse relations of different tu

The rheumatoid arthritis-associated autoantigen hnRNP-A2 (RA33) is a major stimulator of autoimmunity in rats with pristane-induced arthritis

A single intradermal injection of the mineral oil pristane in susceptible DA.1F rats induces erosive arthritis closely mimicking rheumatoid arthritis (RA). Pristane-induced arthritis (PIA) is driven by autoreactive T cells but no autoantigen has been identified to date. We therefore analyzed B and T cell responses to autoantigens potentially involved in the pathogenesis of RA, including IgG, citru

The potential of proton beam radiation for palliation and reirradiation

A group of Swedish oncologists and hospital physicists have estimated the number of patients in Sweden suitable for proton beam therapy. The estimations have been based on current statistics of tumour incidence, number of patients potentially eligible for radiation treatment, scientific support from clinical trials and model dose planning studies and knowledge of the dose-response relations of dif
