A search for murarregamma at the level of 10-13
- 1991

Conference paper (peer-reviewed)abstract
- The MEGA experiment, which is a search for the decay murarregamma with a branching ratio sensitivity of about 10-13, employs highly modular, fast detectors, state-of-the-art electronics, and a staged trigger with on-line filters. The detectors are contained in a 1.5-T solenoidal field produced by a superconducting magnet. Positrons are confined to the central region and are measured by a set of thin MWPCs. Photons are measured by one of four layers of pair spectrometers in the outer region. Most aspects of the design have been validated in engineering runs; data taking will begin in 1990 with much of the electron arm and one pair spectrometer layer installed.

Body sizes and other human factors differences between Swedish and foreign students in Swedish universities

Conference paper (peer-reviewed)abstract
- Past studies have shown large differences in body size between people of Industrialized Countries (ICs) and Industrially Developing Countries (IDCs). These differences can have negative effects on the usage of technology which IDCs today acquire to a great extent from ICs. At the same time, the number of students from IDCs seeking education and training in universities in ICs is increasing. This paper reports on the impact of human factors differences particularly body size differences between foreign and local students on the use of university facilities, based on anthropometric and questionnaire surveys carried out on a small scale by foreign graduate students of Lulea University, Sweden. The study revealed large differences in body sizes between local and foreign students. The questionnaire survey of foreign students showed that there are other significant human factors differences such as the use of a foreign language, viz. Swedish which is unique to Scandinavia, and the exposure to long cold winters. Whether these differences in human factors influence the acquisition of knowledge or learning capacity of foreign students is worth further investigation.

Beneficial-effects of Platelet-activating-factor Receptor Antagonist Web-2170 On 90-minute Hepatic Inflow Interruption
- 1994
-
In: European Journal of Gastroenterology and Hepathology. - 1473-5687. ; 6:11, s. 1015-1022
-
Journal article (peer-reviewed)abstract
- Objective: To study the effects of different doses of platelet activating factor receptor antagonist WEB 2170 on animal survival, haemodynamics, reperfusion and ultrastructural changes in the ischaemic liver in rats undergoing 90-min total hepatic inflow interruption (THII). Design: Sixty-five rats were divided into five groups. All animals underwent 90-min THII. Group 1 served as controls. Group 2 underwent THII alone. Group 3 received an intravenous injection of 1 mg/kg WEB 2170 prior to THII. Group 4 received a bolus injection of 3 mg/kg WEB 2170 before THII. Group 4 received a bolus injection of 3 mg/kg WEB 2170 before THII. Group 5 received 3 mg/kg WEB 2170 before, during and after THII. The liver reperfusion index using laser Doppler flowmetry, the time of ischaemic liver initiative reperfusion, and scanning electron microscopy were performed to evaluate the results of different dose schedules. Setting: Lund University Hospital, Lund, Sweden. Results: Animal survival rate, liver reperfusion index, the time of ischaemic liver initiative reperfusion and ultrastructural damage of the ischaemic liver were markedly improved in the groups treated with WEB 2170 compared with the non-treated 90-min THII group. The best result was obtained in the group receiving the three separate doses. Conclusion: In the 90-min THII model, WEB 2170 protects the liver from ischaemia-reperfusion injury and the spread of damage to the post-stasis splanchnic organs. These beneficial effects may be extended to hepatic transplantation or major resections of the liver.
