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

The chapter deals with the problem how history is used to promote a regional consciousness, focusing mainly on the Barents region.

Dust measurements have been obtained with the dust detector onboard the Galileo spacecraft inside a distance of about 60RJ from Jupiter (Jupiter radius, RJ = 71,492 km) during two periods of about 8 days around Galileo's closest approaches to Ganymede on 27 June and on 6 Sept 1996. The impact rate of submicrometer-sized particles fluctuated by a factor of several hundred with a period of about 10

Background and objective: Human studies of arterio-venous (AV) differences in drug concentrations and the consequences for pharmacokinetic modelling and concentration-effect relationships are very limited. We therefore investigated the intravenous and intra-arterial concentrations of alcohol (ethanol) during the absorption, distribution and elimination stages of alcohol metabolism in healthy men.

Popular Abstract in Swedish Hur kan det civila samhället bidra till demokratisk utveckling? Inom demokratiseringsforskningen framställs ofta det civila samhället som ett centralt inslag i demokratiseringsprocessen. Vi saknar emellertid tydliga teoretiska föreställningar om vilken funktion det civila samhället fyller i en demokrati och om hur det civila samhällets organisationer kan bidra till demoCivil society is frequently singled out as one of the most important factors in the democratization process, but existing research is often imprecise with regard to civil society’s relation to democratic development. This study analyzes how, and under what circumstances, civil society can contribute to democratic development in newly established democracies. A conceptual framework is outlined that

The cytogenetic, clinical, and immunologic findings ina 4-month-old girl with acute lymphoblastic leukemia (ALL) are reported. The malignant lymphoblasts were characterized cytogenetically by the reciprocal translocation t(11;19)(q23;p13); immunologically by an immature pre-B-ALL phenotype. In spite of the high-risk nature of the leukemia, the patient attained complete remission relatively quickly

Interactions between host plasminogen (Plg) and streptokinase (SK) secreted by group A streptococci ( GAS) have been hypothesized to promote bacterial invasion of tissues. The virulence of GAS strain UMAA2616, after being subcutaneously inoculated into mice, was studied. Skin lesions and mortality were observed after inoculation of 7 x 10(6) cfu. Coadministration of human Plg with UMAA2616 markedl

We report, for what we believe to be the first time, on remote imaging laser-induced breakdown spectroscopy (LIBS). Measurements have been performed by using a tripled Nd:YAG laser working at 355 nm with 170 mJ pulse energy, with an expanded beam that is focused onto a target at 60 m distance. The LIBS signal is detected by using an on-axis Newtonian telescope and an optical multichannel analyzer.

In this article, the structure of two-sided ideals in the q-deformed Heisenberg algebras defined by the q-deformed Heisenberg canonical commutation relation AB-qBA=I is investigated. We show that these algebras are simple if and only if q = 1. For q not equal 1, 0 we present an infinite descending chain of non-trivial two-sided ideals, thus deducing by explicit construction that the q-deformed Hei

The Furongian (upper Cambrian) Leptoplastus Zone marks a time of critical changes in the evolution of olenid trilobites. This zone, unexposed at Andrarum in Skane, southern Sweden, has been re-excavated and the sequence of faunas and sediments logged in detail. The faunal succession accords with that previously described from borehole cores by Westergard, and the subzones of L. paucisegmentatus, L

We report on a study of singlet-singlet annihilation kinetics in a series of Zn(II)-porphyrin-appended dendrimers, where the energy transfer efficiency is significantly improved by extending the molecular chain that connects the light-harvesting chromophores to the dendrimeric backbone with one additional carbon. For the largest dendrimer having 64 Zn(II)-porphyrins, only 10% of the excitation int

I present data on seasonal variation in wing length and mass of Red Admirals Vanessa atalanta captured on Capri, Italy, during spring and autumn. The Red Admiral is a migratory butterfly that migrates north throughout Europe each year and then heads back south in the autumn. During the winter they are mostly found in the northern Mediterranean area where they previously were thought to hibernate,
