Detta arbete syftar till att ?ka f?rst?elsen f?r kopplingen mellan elevers l?sf?rm?ga och textprobleml?sningsf?rm?ga. Textproblem utg?r ofta kopplingen mellan matematiken och verkliga situationer, n?got som har potential att g?ra matematiken meningsfull f?r eleverna. Trots detta finns brister i elevers f?rm?ga att f?rst? och l?sa textproblem, vilket vi misst?nker kan vara ett resultat av bristande l?sf?rm?ga.

Sexual risk-taking among teenagers has rapidly increased and only during the last decade the existence of Chlamydia has more than tripled. The future is facing big challenges to cope with the problem. Though the big efforts made on preventive work, Chlamydia continues to spread. The study aims to examine the existing attitudes towards sexual risk-taking among teenagers. The central mode of procedure is to use qualitative focus group interviews, and is complemented with a quantitative survey. A total of 30 teenagers, 15 boys and 15 girls, age 16-20, are participating from three different high schools in Gothenburg.

Light has always fascinated humans but ever since the invention of the first light bulb, the use of artificial lighting has accelerated dramatically. Darkness has never been as rare as today and the overuse of lighting has created a new phenomenon called light pollution. Most living beings are biologically dependent on the recurrent twenty-four-hour rhythm of light and darkness, called the circadian cycle. Human beings are evolutionary developed after this circadian rhythm and the effects of constant artificial light is yet unknown. Scientists fear the consequences of constant lighting and what it means physically, mentally and philosophically for the human species.

Detta arbete a?r en sja?lvstudie i att utveckla improvisation pa? saxofon. Syftet a?r att utforska hur det a?r mo?jligt att uppna? en niva? av frihet i det improviserade spelet. En grundtanke som presenteras i inledningen a?r att all musik egentligen kommer ur improvisation.

Bristly swan-neck moss (Campylopus atrovirens) is in Sweden a very rare moss that only grows on a few blocks and cliffs around Gothenburg. The species can globally only be found in areas with high precipitation. Rain fall in Gothenburg has increased with a stronger greenhouse effect. Air pollution in Gothenburg has also improved. Mosses generally benefit from these conditions and this papers hypothesis is that the population of the species has grown because of these more beneficial conditions.

Frysförvaring av deg innan gräddning av bröden är vanligt förekommande hos många bagerier. Metoden har flera fördelar och möjliggör en mer rationell drift. Det sker dock ofrånkomligt en påverkan av brödens kvalitet vilket ställer krav på tillverkningsprocessen. Tillvägagångssätten vid bakning med frysta degar kan variera från att frysa ned ojästa degämnen till att grädda bröden halvklara innan nedfrysningen. Detta projekt fokuserar det på den förstnämnda metoden, dvs.

Syftet med denna studie ?r att kvalitativt unders?ka hur elever med behov av extra anpassningar och s?rskilt st?d beskrivs fr?n 1962 fram till idag i Sveriges l?roplaner. Studien ?mnar ?ven att unders?ka hur de delar som behandlar fritidshemmet beskriver elever i behov av st?d. Materialet analyserades genom en Foucauldiansk inspirerad diskursanalys d?r diskursbrott och utest?ngningsprocedurer anv?nds f?r att studera analysmaterialet.

Denna litteraturstudie syftar till att unders?ka nollans historiska utveckling samt l?rares, l?rarstudenters och elevers f?rst?else av division med noll. Forts?ttningsvis behandlas fr?gan om matematikhistoria kan anv?ndas i undervisningen f?r att gynna elevers f?rst?else f?r noll och division med noll. Materialet utg?rs av vetenskapliga artiklar, svenska matematikl?rob?cker f?r mellan- och h?gstadiet samt den svenska l?roplanen [Lgr22]. Metoden ?r en kvalitativ litteraturstudie som innefattar historisk granskning, analys av didaktiska studier och en l?roboksunders?kning.

Helicobacter spp. är gramnegativa bakterier med en spiralformad, böjd eller rak kropp utan några förgreningar. De har en snabb och riktad rörelseförmåga mot magsäckens slemhinna tack vare sina flageller som kan vara unipolära eller bipolära. Virulensfaktorerna varierar inom släktet. Rörelseförmågan påverkas av kroppsutformning och flageller, men även antal adhensiner och möjlighet till ureasproduktion är viktiga virulensfaktorer.

Children?s utterances have been studied in different languages; however, only a few studies refer to Swedish. The aim of the present study is to describe utterance types, subordinate clauses and utterance length for a group of three and four year old Swedish children without known functional impairments.The study included 29 children, 17 girls and 12 boys, in a larger city in the south-east of Sweden. The children, all native Swedish speakers, were aged 3;0 to 4;11. Sound recordings were made during a playing session with one of the authors in the children?s day care centers.The utterances were divided into the categories elliptical responses, incomplete and partly unintelligible utterances, imitative utterances and independent utterances.

This essay discusses the interaction between the authorities in Nacka municipality in Sweden and supervisors within the eldercare. In Nacka politicians have gradually started delegate responsibility for how care-giving for the elder should be done and focus instead on formulating economical objectives and overall rules. It is up to the approved supervisors of eldercare to deliver good care and quality. The method chosen to accomplish this is public choice. This method is a part of the big New Public Management (NPM) reform which have had a big impact on Swedish public sector since the 1980´s.

The increased frequency of reported Methicillin-resistant Staphylococcus pseudintermedius (MRSP) is of great concern to small animal healthcare due to limited options of antimicrobial therapy. The aim of this literature study is to investigate 1) characteristics and classification of S. pseudintermedius, 2) resistance mechanisms and emergence of MRSP, 3) risk factors for selection of MRSP, and 4) clonal distribution around the world. S. pseudintermedius is a skin and mucosal commensal in healthy dogs and cats, but can cause infections, including pyoderma. Beta-lactam antibiotics inhibit bacterial growth by binding to the penicillin binding protein (PBP), a vital enzyme in the synthesis of the bacterial cell wall.

I denna studie unders?ktes hur matematikundervisning med yngre barn utf?rs och vilka olikaartefakter som barnen v?ljer. Enligt l?roplan f?r f?rskolan, Lpf? 18, ska f?rskolan skapam?jligheter f?r barnen att m?ta s?v?l planerad som spontan matematikundervisning. Det tarsin utg?ngspunkt i barnens tidigare erfarenheter och intressen (Skolverket, 2018).

Flooding events are no longer rare, floods occur all over the world. Accordingly, it is vital for the society and different authorities to work with flood mapping. To meet the goal of Uppsala kommun to map the risks of floods in Uppsala län, a map of the different areas around Funboån which are inside the area of risk for flooding have been developed.In the work, cross sections and the water flow have been measured. Moreover, an echo-sounding have been carried out in Funboån to map the bottom topography. From the bottom map and laser scanned data covering the study area, a terrain model was created.
