In this study of the transfer function of copies of the Vienna-type differential mobility analyser (DMA) it was found that three, supposedly identical, DMAs exhibited distinct differences with respect to the width of the transfer function. This means that the transfer function of a DMA needs to be determined on an individual basis in order to obtain accurate results from DMA measurements. The size

The enzymatic and bioelectrocatalytic activity of tyrosinase from mushrooms was studied in a system of reversed micelles formed by Aerosol OT (AOT) in hexane. The optimal catechol oxidising activity of tyrosinase incorporated in reversed micelles was found at a hydration degree of w(0) = 25. The catalytic activity was comparable with tyrosinase activity in aqueous media. When immobilized at an Au

During two consecutive years 607 individuals with lower limb fractures were diagnosed. Half of the individuals, 315, were women and only 14 of them had an earlier registration for alcoholism. In the 292 men, however, 73 men or 25%, had been registered at the Department of Alcohol Diseases at least once during the 13 years of observation, the highest registration frequency (30%) was noted in the ma

The sensitivity to geometrical imperfections of various test methods for wood-adhesive bonds was investigated using nonlinear finite element analysis. The adhesive layers in the specimens were modelled using a nonlinear softening, fracture mechanics model. The specimen types corresponded to the standards according to ASTM-D4680, ASTM-D905, EN-302-1 and a modified version of the ASTM-D3535 specimen

Rat liver microsomes contain two distinct forms of PtdIns 4-kinase which were resolved by heparin-Sepharose chromatography. One enzyme was identified as the type II PtdIns kinase previously isolated from exocytotic vesicles. The other enzyme, however, was a novel PtdIns 4-kinase isoform with properties differing from any other PtdIns kinase so far characterized. Both kinases were recognized by a m

The cause of retinopathy in diabetes mellitus is unknown. Among factors suggested to be involved in the development of retinopathy is altered platelet function. In the present study, platelet aggregation was measured in vitro after stimulation with adenosine diphosphate (ADP) and collagen in patients with and without proliferative retinopathy. The results show that patients with proliferative reti

Background and aims: Monochromatic pulsating light may have effects of importance for wound healing, and promising results were obtained in an open study on the healing of pressure ulcers, which motivated the present study. Methods: One hundred and sixty-four in- and outpatients with grade II and III ulcers were treated with monochromatic pulsating light or placebo over the ulcerated area, accordi

Darwin’s finches are an iconic bird group that has transformed our perception of evolutionary dynamics in wild populations. Surprisingly, the parasites and diseases of these finches are virtually unstudied. This study simultaneously investigates blood and intestinal parasitism in Darwin’s Small Ground Finch Geospiza fuliginosa and intestinal parasitism in the Medium Ground FinchGeospiza fortis. We

This article deals with the limits of divine power in the Old Testament. The aim is to show how one of the traditional attributes from ancient philosophical metaphysics, namely, omnipotence, does not fit the depiction of YHWH in the Hebrew Bible. The biblical traditions know of several limitations of divine power that must be reconciled to regional and functional limits, and the one must difficult

Studies spirituality in the Commentary on Joshua by the Benedictine monk Irimbert of Admont. Special attention is given to the author's use of ornate language (rhyme) and logical argument (reason).

The first lifetime measurements for doubly ionized uranium are reported in the present work. They relate to five levels belonging to the configurations 5f(2)6d(2), 5f(2)6d7s and 5f(3)7p and have been obtained with a time-resolved laser-induced-fluorescence technique, the ions being produced by laser ablation of a uranium oxide target.

Abstract in Undetermined This volume contains essays by five British philosophers and one Swedish philosopher working in metaphysics and in particular metaphysics as it relates to the philosophy of science. These philosophers are the core of a tight network of European philosophers of science and metaphysicians and their essays have evolved as a result of workshops in Lund, Edinburgh, and Athens.

Neurons have been neglected as cells with a major immune-regulatory function because they do not express major histocompatibility complex class II. Our data show that neurons are highly immune regulatory, having a crucial role in governing T-cell response and central nervous system (CNS) inflammation. Neurons induce the proliferation of activated CD4+ T cells through B7-CD28 and transforming growt
