Objective: Individual-based studies on restricted geographical settings have suggested that nonsteroidal anti-inflammatory drugs (NSAIDs) may precipitate congestive heart failure. As NSAID use is very extensive, it might increase the occurrence of symptomatic heart failure in the general population. Therefore, in order to study the impact of NSAID utilisation (prescribed and over the counter) on h

Popular Abstract in Swedish Denna studie rapporterar ett undervisningsförsök i en 8:e klass (age 14-15) med 20 elever. Eleverna har bearbetat en naturvetenskaplig problemställning om växthuseffekten och jordens globala uppvärmning utifrån ett problemlösande och informationssökandarbete i grupp. Deras uppgift har varit att beskriva de fenomen och faktorer som påverkar jordens globala temperatur i oThis study gives an account of a teaching situation in the eighth grade with 20 student's aged 14-15. The students have worked with a scientific problem focussed on the greenhouse effect and the earth's global warming, based on a problem solving and information seeking way of working in groups. Their task has been to describe the phenomena and factors that influence the earth's global temperature

Sediment-dispersed extraterrestrial chromite grains (63-355 mu m) have been recovered in a section across the Arenig-Llanvirn transition in the Killerod quarry in southeastern Scania. Previous studies of the same stratigraphic interval in the Orthoceratite Limestone at Kinnekulle, ca. 350 km to the north in Vastergotland, have shown a two orders of magnitude increase in extraterrestrial chromite b

A set of equations are put into a code forming a procedure to derive intensities of fluorescence lilies based on both physical properties of the fluorescent plasma and its location relative to the origin of the pumping emission. In a first test, the code is applied to symbiotic stars, and effort is made to explain the circumstances under which the two known Fell channels pumped by C IV are activat

Signal processing can be used to condition medical signals to facilitate their interpretation, and to extract clinically important information. The purpose of the present doctoral thesis is to put forward solutions to certain problems encountered in the processing of electrocardiac signals. Paper I examines the properties of a maximum likelihood method for aligning vectorcardiographic loops, with

Dwarf eggs, e.g. eggs that are very much smaller than normal eggs, are occasionally found among normal eggs in nests of birds. Although they are not often mentioned in the handbooks, the frequency of dwarf eggs seems to be about one per thousand, or less. In 2001 I found one dwarf egg in a nest with two eggs of the Long-tailed Skua Stercorarius longicaudus at Ammarnas in Swedish Lapland. I did not

In the region near 1 µm, we have found laser action in a quantum transition between highly excited states of Fe II, with its higher levels being optically pumped by the intense H Ly radiation (1215 Å) formed in the ionized HII region of a gas condensation (blob B) in the close vicinity of the central star in Carinae.

Background. Skin grafting may be necessary to close nonhealing skin wounds. This report describes a fast and minimally invasive method to produce minced skin suitable for transplantation to skin wounds. The technique was evaluated in an established porcine skin wound healing model and was compared to split-thickness skin grafts and suspensions of cultured and noncultured keratinocytes. Materials a

For a bounded open set $U$ in the complex plane, we consider the Bergman space $L^p_a(U)$ of $p$th-power area-integrable analytic functions on $U$, with $p$ assumed to be in the range $1\le p

Aim: To investigate the anatomical and functional results and the complications in eyes operated on using vitrectomy without scleral buckling for all forms of rhegmatogenous retinal detachment ( RRD). Methods: All cases of primary RRD at the University Hospital of Lund, Lund, Sweden, treated by one surgeon during a period of 3 years were retrospectively reviewed. In 131 ( 98%) of 134 consecutive c
