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.

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.

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.

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.

The most common form of female cancer in Sweden is breast cancer and the primary choice of treatment is surgery. Removing a woman's breasts is not just removing a body part but is also strongly linked to the emotional life. This has psychosocial consequences and the reactions will be different depending on how people perceive health and illness. Factors that matter are both personal experiences and cultural factors such as religion, family, and the own standards and values. It is important that a nurse is aware of cultural factors that may influence the perception of care.

Syftet med studien ?r att unders?ka upplevelser hos yrkesverksamma som arbetar med att till?mpa djurunderst?tt arbete med hund inom ?ldreomsorgen och/eller arbetar i en s?dan verksamhet d?r hundinterventioner till?mpas. Studien str?var efter att f? insyn i de yrkesverksammas upplevelser om hundinterventioner inom ?ldreomsorgen, med fokus p? hur dessa insatser kan inverka p? ?ldres sociala delaktighet, psykiska v?lbefinnande och motivation till socialt engagemang. Studien genomf?rdes genom kvalitativa intervjuer med sex personer som arbetade antingen p? ett ?ldreboende d?r djurunderst?tt arbete med hund implementerats, eller som hundf?rare som bes?kte s?dana verksamheter.

Periods of hypoxia are a recurring issue in Brunnsviken. Main factors that trigger hypoxia in Brunnsviken are eutrophication  due to anthropogenic emission of nutrients, stratification in the water column due to salinity and temperature differences  that prevents mixing and a sill inlet that prevents water exchange. As an attempt to improve the oxygen levels, bottom water is pumped from Brunnsviken causing aerated surface water to flow back into the basin.  The objective of this Master?s thesis was to study the change in dissolved oxygen levels due to pumping.

Syfte: Syftet med denna uppsats är att undersöka finansiella institutioners syn på hävstångsinstrument och utifrån detta utreda om instrumenten är ett bra investeringsalternativ för småsparare.Metod: Uppsatsen har en kvalitativ inriktning då tre intervjuer har genomförts för att besvara syftet. De finansiella institutionerna som intervjuades är Handelsbanken, CMC Markets och SIP Nordic fondkommission.

Utifrån intervjuer och tidigare studier har en slutsats sedan utformats för att besvara syftet. Resultat & Slutsats: Uppsatsens resultat talar för att hävstångsinstrumenten är ett bra alternativ för småsparare som är intresserade, risktoleranta och aktivt söker kunskap.
