The distribution of necks in slender structures obtained using high rate deformation often differs from the distribution obtained under quasistatic conditions. Initial thickness imperfections are often used to initiate necking at certain locations along a specimen surface. At sufficiently large deformation rates, necks may develop at sites that correlate weakly or not at all with the sites of the

Abstract in Danish Formål: Formålet er at beskrive tuberkulosens (tbc.) epidemiologi i Danmark de sidste 25 år, specielt udviklingen i den danske befolkning. Metode: Et registerstudie af anmeldte tilfælde af tbc. i Danmark 1972-1996: Fra 1970-1989 i DIKE's register, fra 1990-1996 i EPI-registeret, epidemiologisk afd., Statens Serum Institut. Resultater: tbc.-incidensen faldt jævnt fra 1972 indtiThe present study is based on notified cases of tuberculosis (TB) in the National tbc. register 1972-1996. A decline in Tb incidence was seen from 1972 and until the mid-1980's. Subsequently the trend has reversed due to an increasing number of TB cases in foreigners. In 1996, 60% of all cases of TB in Denmark were found in foreigners reflecting the rising number of refugees and their families arr

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

Structural and mechanical alterations during hypertrophy of the rat portal vein were investigated. Growth of the vessel was induced by a partial ligature of the vessel causing an increased transmural pressure. Vessel segments from animals kept with ligature for 1, 3, 5 and 7 days, were compared with vessels from sham-operated animals. Maximal active force and vessel cross-sectional area increased

Dual-broadband pure rotational coherent anti-Stokes Raman spectroscopy was investigated in terms of thermometry and species concentration measurement for studies of combustion. The modelling of rotational CARS spectra under conditions of high pressure at room temperature was investigated. Resonant terms of the Stokes (CSRS) type were found to have a significant effect on the intensity of the anti

This article outlines an experimental and numerical study on Poisson’s ratio of High Performance Concrete, HPC, subjected to air or sealed curing. Eight qualities of concrete (about 100 cylinders and 900 cubes) were studied, young and in the mature state. The concretes contained between 5 and 10% silica fume, and two concretes in addition contained air-entrainment. Parallel studies of strength and

This paper critically reviews reconstructions of cultural development in prehistoric Amazonia and argues for the primacy of regional and interregional exchange in generating the complex distributions of ethno-linguistic identities traced by linguists and archaeologists in the area. This approach requires an explicit abandonment of notions of migrating "peoples" in favor of modern anthropological u
