Volatiles from Ips duplicatus male hindgut extracts and aeration samples of spruce logs colonized by the virgin males were analyzed by coupled gas chromatography-mass spectrometry (GC-MS), coupled gas chromatography-electroantennographic detection (GC-EAD), and field trapping bioassays in Inner Mongolia, China. GC-MS analyses showed that males from nuptial chambers (for reproduction) produced hind
A miniaturized on-column digestion system constructed for the sequential analysis of semi-purified protein analytes is presented. By utilizing fused silica capillary (diameter 150 mu m) packed with a zone of trypsin-modified Eupergit C beads and a second zone of reversed-phase C18 material, a linear column set-up was constructed. The protein analytes (pmol amounts) were first digested in the 600 n
Six pigs were used to study whether the collection of shed blood by means of surgical compresses instead of suction traumatizes such blood. In an in vivo part of the study, the whole blood volume of the pigs was retransfused after treatment with citrated compresses, and in an in vitro part the blood was treated extensively with compresses and analyzed. All animals survived, with a minor fall in he
The charged particle production in ultra-relativistic nucleus-nucleus collisions in the energy range 4-200 A GeV has been studied. Two different experimental techniques have been utilized: nuclear emulsions and Multi-Step Avalanche Chambers. Four large Multi-Step Avalanche Chambers with optical read-out were included in the experiment WA93 and were used to reconstruct the tracks and determine the
This paper investigates the use of data-adaptive spectral estimation techniques for blood velocity estimation in medical ultrasound. Current commercial systems are based on the averaged periodogram, which requires a large observation window to give sufficient spectral resolution. Herein, we propose a novel data-adaptive method to form the blood velocity spectral estimate. The method is evaluated u
Methods of VUV electron beam ion trap (EBIT) spectroscopy are applied to the study of Pm-like tungsten (W13+). These data show that theory appears well capable of dealing with these multi-electron (61) ions, at least for high ionization stages. A comparison of other spectroscopic methods applied to the study of other ions of the Pm I sequence is also given, and finally a search for the Pm-like W l
OBJECTIVE - we sought to study the frequency of P-cell-specific autoantibody markers in women with gestational diabetes mellitus (GDM) and to follow these women to estimate the risk of later development of type I diabetes. RESEARCH DESIGN AND METHODS - Of 385 pregnant women with GDM during 1995-2005 in the district of Lund, 24 (6%) women were found positive for at least one of the following: islet
A novel insertion device for electron storage rings, called the MAX-Wiggler [Nucl. Instr. and Meth. A 467-468 (2001) 118], has been constructed at MAX-lab. The MAX-Wiggler is a cold bore superconducting wiggler magnet with 47,3.5 T poles and a period length of 61 mm. It is designed for the production of X-rays at the 1.5 GeV electron storage ring MAX-II [Nucl. Instr. and Meth. A 343 (1994) 644] at
Several unconventional accelerator technology solutions were introduced in the MAX II electron storage ring during the 1990s, such as quadrupole magnets with integrated sextupoles, non-zero dispersion in the straight sections and a common girder for all magnets in the same cell. The lattice of the MAX II ring has been characterised in order to evaluate these solutions, to assist in MAX II operatio
In the Nordic Reference Interval Project 2000 (NORIP) serum, Li-heparin plasma and EDTA buffy coat were collected at 102 laboratories in 5 Nordic countries from healthy individuals aged 18 years or more and evenly distributed for laboratory, gender and age. Multiple aliquots of these samples from each of about 3000 persons are now stored at the Nordic Reference Interval Project Bio-bank and Databa
Abstract in Norwegian Artikkelen presenterer de skandinaviske helgenene Theodor væringen og sønnen Johannes, Russlands protomartyrer med utgangspunkt i russiske kilder, men utifra et skandinavisk perspektiv. Den presenterer likeens den hellige Anna (Ingegerd) av Novgorod med utgangspunkt i både russiske og norrøne kilder.
The ability of a nematode-trapping fungus to establish in field soil is an important characteristic when considering its use as a biological control agent. The outgrowth of the nematode-trapping fungus Arthrobotrys superba from wood was recorded by labelling the fungus with [14C]3-O-methylglucose and [32P]orthophosphoric acid and by using the soil sprinkling method. The fungus reached a distance o
