The incidence of evaporating `black widow' pulsars (BWPs) among all millisecond pulsars is far higher in globular clusters than in the field. This implies a special formation mechanism for them in clusters. Cluster millisecond pulsars in wide binaries with white dwarf companions exchange them for turnoff-mass stars. These new companions eventually overflow their Roche lobes because of encounters a

Printed almanacs in the Danish language are preserved from the sixteenth century. The production of almanacs increased from the 1570’s just as that of news sheets, pamphlets, and chapbook stories. From the beginning the almanac covered a sheet of paper consisting of 16 leaves, or 32 pages. As a supplement, four or eight leaves of paper contained the Practica Astroligica. This form – 40 or 48 pages

This chapter investigates the location pattern (at the NUTS 2 level) of European-based star scientists (identified by the number of citations they generated in journals in the ISI database) as well as the degree and intensity of knowledge sharing activities performed by the scientific elite in their regions of choice. Using a unique dataset of 197 star scientists, we demonstrate that Europe’s worl

Spectra of hot (type B) stars obtained with the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite in the region 1000-1200

The report gives an account on PhD-training in the five Nordic and three Baltic countries as well as Russian and Germany.

In this paper, an automatic method for reducing chemical mechanisms during run time based on the quasi-steady-state assumption (ASSA) is presented. The method uses a lifetime analysis of the chemical species which can be set to steady state according to a ranking procedure. Steady-state species concentrations are computed by algebraic rather than differential equations, thus yielding a significant

We examined temporal and geographical distribution of Haemoproteus sp. and Plasmodium sp. parasites in Swedish willow warblers, Phylloscopus trochilus. Parasite lineages were detected with molecular methods in 556 birds from 41 sites distributed at distances up to 1,500 km. Two mitochondrial lineages of Haemoproteus sp. were detected, WW1 in 56 birds and WW2 in 75 birds, that differed by 5.2% sequ

A study to determine and compare the sensitivities and specificities of the comparative cervical tuberculin (CCT) and gamma-interferon (IFN-gamma) tests for the diagnosis of bovine tuberculosis was conducted on 30 zebu oxen. The results of the tests were compared with the presence of acid-fast bacilli found by bacteriological culturing and histopathological examinations. The sensitivity and specif

Six pure strains of obligate anaerobes capable of degrading the toxin beta-N-oxalyl-L-alpha, beta-diaminopropionic acid (beta-ODAP) contained in grass pea (Lathyrus sativus) have been isolated from cow rumen. The new isolates were identified as Megasphaera elsdenii (five different genotypes) and Clostridium bifermentans using 16S rDNA analysis. The beta-ODAP degrading efficiency of the isolates wa
