Solitary bees and bumblebees have declined substantially throughout western Europe during the last 100 years. Many species are important pollinators and are associated with particular plant species and habitats. In this study we report the highest number of bee species found at one locality in Sweden (Table 2). In total 87 species of wild bees (74 species of solitary bees and 13 species of bumble

Popular Abstract in Swedish Hur kan man förklara vardagligt tänkande med de kognitiva teorier som finns tillhands idag? Ofta är dessa teorier konstruerade för att kunna förutsäga beteende under kontrollerade omständigheter, som i ett laboratorium. Å andra sidan är det snarare flexibilitet och improvisation som kännetecknar det vardagliga tänkandet. I avhandlingen försöker jag ta reda pa vad man måHow well can we explain natural occurrences of cognitive behaviours given the theoretical frameworks available to us today? The thesis explores what has to be assumed in cognitive theory in order to provide such an explanation, in contrast to being able to predict behaviour under controlled circumstances. The behaviours considered are all of the type described as involving higher level cognition

Maritime transportation is a significant contributor to SOx, NOx and particle matter emissions, and to a lesser extent, of CO2. Recently new regulations are being enforced in special geographical areas to limit the amount of emissions from the ships. This fact, together with the high fuel prices, is driving the marine industry towards the improvement of the energy efficiency of ships. Although mor

This thesis deals with numerical simulation of reactive flows. The numerical method is three dimensional and unsteady, which allows for spatial and temporal resolution of most of the scales of the fluid motion and the reaction process. In the turbulent cases studied, scales down to Taylor scales are resolved. Hence, it can be considered to be a large eddy simulation, LES. In the laminar cases stud

A discussion about biographical methods and a comparision between my biography of Oscar I, swedish king 1844-1859, and my biographies of women in the 1900-th century.

My purpose in this article is to make a contribution to what the legal philosopher H.L.A. Hart (1907-1992) has to say about providing a sociological understanding of law and to apply Hart's theory in relation to a specific area of law. The specific legal area consists of the violation compensation that victims of crime can obtain from the Crime Victim Compensation and Support Authority in Sweden.

Values among individuals having client-related jobs and organisations in client related sectors might differ from values in their counterparts in jobs and sectors that are not client-related. It is possible that jobs that include interactions with other people demand more developed moral thinking. This report is a description of differences that has been found in a comparison between a ward in the

Artikeln diskutera konservatismens etos som en specifik mänsklig grundhållning. Fyra aspekter lyfts fram: 1. Avsked från det principiella. 2. Anknytning till det redan förefintliga. 3. En pluralistisk etik. 4. En institutionell etik.

Popular Abstract in Swedish Vi vill bevara naturbetesmarker och deras skönhet, vilken bland annat utgörs av de olika växtarter som förekommer där. Men idag finns det tyvärr inte många betesmarker kvar. Naturbetesmarkerna har under de senaste två sekelerna försvunnit på grund av ökad eller minskad markanvändning, där betesmarker blivit omvandlade till antingen åkermark eller skog. Bristen på betesmLarge areas of grazed, species rich semi-natural grassland were lost in Europe during the last two centuries and as a consequence led to decreases in grassland specialist species. Therefore, today the “restoration” of grassland on previously arable fields is recommended for the protection of grassland specialists. Even “substitute habitats” for lost grasslands are discussed as temporary alternativ

REX is a Fortran program for analysis of spectra obtained in PIXE analysis. The underlying model is still under development; however, one year of experience has demonstrated REX’s capability to be a fast reliable tool. The modeling of the different components and effects of the physical model is briefly discussed. Evidence is shown that secondary effects mostly due to Compton-scattering in and aro

The healthcare sector constitutes a major part of the economy of developed nations and consumes significant quantities of consumables. The Region Scania commissioned IIIEE, Lund University, to develop a management tool for strategic decision-making in order to reduce the climate impact indirectly derived from material, consumption. The tool was streamlined to fit operational conditions at Region S
