Modelling the formation of super-km-sized planetesimals by gravitational collapse of regions overdense in small particles requires numerical algorithms capable of handling simultaneously hydrodynamics, particle dynamics and particle collisions. While the initial phases of radial contraction are dictated by drag forces and gravity, particle collisions become gradually more significant as filaments

The study is based upon material which is a part of the Swedish Agency for Education's evaluation of oral production in year five at primary school. The overall aim of this study is to examine w h a t is assessed by describing the childrens speech, developing and testing criteria for the proficiency in speech in relation to this assessment. For qualitative purposes, a description of the phenomenon

Hemmen i den nya verlden(1853-4) is novelist Fredrika Bremer's 3-volume travel diary in letter form, a literary account of her two years' travel in the United States and Cuba. Bremer wove, into the America she "wrote," a number of American authors and their works. Novelist Catharine Sedgwick and poet and socialite Anne C. Lynch exemplified for Bremer the right use of women's moral influence. Crit

Over the past 30 years a vast number of studies have demonstrated the presence of pharmaceutical residues in the environment. But still knowledge is scarce regarding the interaction of these emerging pollutants with various matrices in nature. A chromatographic system with on-line detection was devel- oped to perform a sorption study of six selected pharmaceuticals to four natural sediments and de

The Eurasian spruce bark beetle, Ips typographus, is one of the major forest insect pests in Europe, capable of mass-attacking and killing mature Norway spruce trees. The initiation and development of a new generation are strongly controlled by temperature and a warmer climate may affect the number of generations that is produced per year and hence the outbreak dynamics. Experimental knowledge reg

For the evaluation of the imaging properties of medical radiographic systems there are well-established standards for measuring techniques available, e.g. ISO 9236 for the measurement of the H/D curve. However, such measuring techniques require sophisticated equipment which is not available in a clinical environment. For a clinical routine of image evaluation, techniques like contrast-detail diagr

In decerebrated, nonanesthetized cats, we made intracellular whole-cell recordings and extracellular cell-attached recordings from granule cells in the cerebellar C3 zone. Spontaneous EPSPs had large, relatively constant peak amplitudes, whereas IPSPs were small and did not appear to contribute substantially to synaptic integration at a short time scale. In many cases, the EPSPs of individual moss

We discuss the main properties of the Galactic globular cluster (GC)blue straggler stars (BSSs), as inferred from our new catalog containingnearly 3000 BSSs. The catalog has been extracted from thephotometrically homogeneous V versus (B-V) color-magnitude diagrams(CMDs) of 56 GCs, based on Wide Field Planetary Camera 2 images of theircentral cores. In our analysis, we used consistent relative dist

Popular Abstract in Swedish Villkoren för utbildning och undervisning förändras i väsentliga avseenden i takt med samhällets tilltagande komplexitet. Det är många gånger svårt för både lärare och elever att veta hur man på bästa sätt ska orientera sitt pedagogiska handlande. Med utgångspunkt från tre pedagogiska kontexter - grundskolan, de särskilda ungdomshemmen och grundskollärarutbildningen - pPedagogical practice is, in several important considerations, contradictory in character. In this dissertation attenention is drawn towards the field of tension that prevails between pedagogical action, which can be descibed in terms of strategic processes and communicative pedagogical action. While the former places the preconditions for effective knowledge development of the individual at the ce

In unsparing efforts to find the hidden primaries, second primary cancers (SPCs) unrelated to cancer of unknown primary (CUP) are found. The detection rates of SPCs after CUP can be considered as measures for the effectiveness of modern diagnostic techniques in finding tumors. We aimed to compare the rates of specific SPCs found after the work-up of CUP and the more sign/symptom-directed diagnosti

Although extensive research has demonstrated host-retrovirus microevolutionary dynamics, it has been difficult to gain a deeper understanding of the macroevolutionary patterns of host-retrovirus interactions. Here we use recent technological advances to infer broad patterns in retroviral diversity, evolution, and host-virus relationships by using a large-scale phylogenomic approach using endogenou

Cigarette smoking has inconsistently been associated with an increased risk of colorectal cancer. One of the enzymes responsible for the detoxification of the carcinogenic compounds present in tobacco smoke is glutathione S-transferase-mu (GST-mu). The gene that codes for this enzyme is GSTM1. In this study, we evaluated the associations and interaction between GSTM1 deletion, smoking behaviour an

In the molecular interplay between pathogenic microorganisms and their host, proteolytic mechanisms are believed to play a crucial role. Here we find that the important human pathogen Streptococcus pyogenes (group A Streptococcus) expresses a surface protein with high affinity (Ka = 2.0 x 10(8) M-1) for alpha2-macroglobulin (alpha2M), the dominating proteinase inhibitor of human plasma. The immuno

Heparan sulfate chains have been found to be associated with amyloid deposits in a number of diseases including transmissible spongiform encephalopathies. Diverse lines of evidence have linked proteoglycans and their glycosaminoglycan chains, and especially heparan sulfate, to the metabolism of the prion protein isoforms. Glypicans are a family of glycosylphosphatidylinositol-anchored, heparan sul

Första april 2018 trädde 3 kap. 4 § i skadeståndslagen ikraft. Lagrummet innebär att det offentliga under vissa villkor bär ett skadeståndsansvar för överträdelser av EKMR. Införandet av 3:4 SkL föregicks av en flerårig utveckling av ansvar för konventionsöverträdelser i HD:s praxis. Uppsatsen redogör för 3:4 SkL i förhållande till den första artikeln i första tilläggsprotokollet till EKMR – skydOn the 1st of April 2018 the new law of chapter 3, section 4 in the Tort Liability Act went into force. The law declares that the state under set provisions is liable for damages caused by violations of the ECHR. The law was preceded by several years of development of a convention-based responsibility in the case law of the Supreme Court. This thesis examines the new law in the context of the fir

Japanese knotweed is a big problem in Sweden and there is no known control that can eliminate stands of the plant. Therefore the aim with this thesis is to investigate the effect on Japanese knotweed of two control methods: mowing and hot water. The control methods chosen are the ones used by the Ängelholm municipality since this thesis is done in collaboration with them. The methods were investig

Housing market in Punjab faces number of challenges related to supply, population growth, access to utilities, affordability, and consumer mortgages. In 2017, Punjab, Pakistan, experienced a total urban housing deficit of about 2.3 million units. Due to the Punjab's low supply of affordable housing, home ownership is uneven, with the majority of owners being concentrated in the highest-income

Antalet nyanlända personer i Sverige har ökat dramatiskt de senaste åren. Ansvaret för dessa människors boende är både en statlig och en kommunal angelägenhet. Denna uppsats undersöker ansvarsfördelningen och hur långt rätten till bostad sträcker sig i svensk lagstiftning. Uppsatsen undersöker om rätten till bostad åtnjuts på lika villkor av alla människor som lagligen uppehåller sig i Sverige. DeIn the last years, there has been a largely increased number of refugees in Sweden. The responsibility for these peoples’ living situation are both a responsibility for the state and for the municipalities. Thus, this paper will examine the distribution of responsibility and how far the right to housing extends in Swedish national law. This paper focus on the subject if the right to housing is enj
