Poorly maintained forges are a common sight in the province of Gästrikland. Because of their changed appearance, possible move from the origin location and poor items related knowledge they will rarely qualify for the range of funds available through Länsstyrelsen. Therefore this study deals with the problems associated with the forges in southern Gästrikland, i.e. Hedesunda and Österfärnebo parishes.The aim of the study is to increase the items related knowledge of forges and perhaps form the basis for restoration projects in the area. Eleven forges have been examined and the changes they have undergone have been highlighted.A forge was erected on the farm and was used for the households needs such as producing and repairing tools.

Under en operation behöver patienter tillföras vätska. Det finns en pågående diskussion om vilken sorts vätsketillförsel som har fördelar för patienterna. Framförallt diskussionen om glukos ska tillföras eller inte. Förhöjda blodsockervärden under och efter operation har visat sig ha negativa konsekvenser för morbiditet, mortalitet och vårdtid. Det finns inga entydiga riktlinjer kring peroperativ vätsketillförsel.SyfteAtt se hur plasmaglukosvärdet hos patienter som tillfördes eller inte tillfördes glukosinfusion vid planerad kolorektal kirurgi förändrades över tid, per- och postoperativt, och hur detta påverkade diures och illamående de första fyra timmarna postoperativt.

During my one year master in pedagogic science, I was frequently given the impression that depicts the pedagogue?s profession as a rather transcendent talent or, more precisely, a matter of having ?it? or not. It seemed to me, as if the communicative part of the teacher?s specialised skill was more or less undefined in the description of what makes the pedagogue a professional pedagogue. On those premisses, I was led to the aim of this study, which is pursuing the very essence of the profession by discussing how five teachers validate their daily work from a habermasian perspective on communication, society and pedagogy.

Studies have shown that air pollution, as well as bark fissure depth and sun exposure of a tree can have an effect on lichen growth as well as abundance of lichen species. The aim of this study was to find out the relative importance of these factors. 211 oaks in south eastern Sweden were surveyed for presence of 17 lichen species, as well as the total number of lichen species. Half of the trees were situated in urban areas and half in the countryside. For each tree the bark fissure depth was measured and the sun exposure of the trunk was estimated.

En viktig del av en nations säkerhetspolitiska ambition handlar om att skaffa sig handlingsutrymme. Detta görs genomen orkestrering av nationens olika maktmedel. På militärstrategisk nivå skapar en samordning av politisk målsättning,doktriner och resurser en samlad nettoeffekt, vilken utgör nationens möjliga militära strategi.Efter att det kalla kriget upphört har stora förändringar i den säkerhetspolitiska miljön för bland annat Sverige ägtrum. Sverige har därför förändrat sin säkerhetspolitiska utformning och Försvarsmakten och dess luftstridskrafter harföljt efter. Det svenska flygsystemet skall idag exempelvis kunna användas i av NATO eller EU ledda fredsframtvingandeoperationer.

Bakgrund: I Sverige opereras 24% av de extremt för tidigt födda barn (EPT) för öppetstående ductus arteriosus (PDA). EPT barn som behandlas med ductuskirurgi riskerar få i sig för lite energi och makronutrienter på grund av volymrestriktioner och rädsla för att påbörja enteral nutrition efter genomförd operation och därigenom utveckla nekrotiserande enterokolit (NEC). NEC är ett ischemiskt och inflammatoriskt tillstånd hos prematura barn i vilket delar av tarmen nekrotiseras (vävnadsdöd).Syfte: Att beskriva tillförsel av energi, makronutrienter och vätska inför, under och strax efter ductuskirurgi hos EPT barn.Metod: En svensk populationsbaserad kohortstudie av EPT barn födda mellan åren 2004-2007 och som opererats för PDA (n=140, 83 pojkar, genomsnittlig födelsevikt 723 g). Utförlig information avseende perioperativ nutrition inhämtades retrospektivt från sjukhusjournaler. Det dagliga intaget av enteral- och parenteral nutrition samt blodprodukter användes för beräkning av intaget av energi, makronutrienter och vätskevolymer tre dagar före fram till och med tre dagar efter operation.

The sandy beaches of Vänern are threatened by overgrowth and thereby the biodiversity is at high risk to decline. This study is based on an inventory of vegetation of overgrowth character and mosses. The frequency and spread of mosses is perceived as an indication of initial or present overgrowth. External factors that have been taken into consideration are wind-, wave- and ice erosion, the slope of the beach, wear and grade of exposure. The purpose of the investigation is to control the beaches grade of overgrowth and find out which external factor is of most importance for the maintenance of the biotope. The results show that the beaches environment is affected by the slope of the beach, grade of exposure, size, wear and overgrowth.

This thesis was commissioned by Tekniska verken, Energy Division with the overall aim to investigate the concept of environmental debt and what it means for a business. Furthermore, a sustainable risk and responsibility investigation shall be carried out on the concerned areas. Finally, the priority areas shall be highlighted and proposed actions presented. The Swedish Environmental debt concept was presented in 1992 by Arne Jarnelöv. Environmental debt is defined as restoration costs for environmental damage. In the early days the concept did not take into account who was responsible, but the environmental debts was regarded as a humanity debt to future generations.

The essay is written at the request of Nyköping municipality park management by PatRadestedt who wanted a design proposal for one of the five courtyards at the Tessin Schoolin Nyköping. The Tessin School is located 2 miles from the center of Nyköping and the schoolhouses approximately 900 students. To make a design proposal for the courtyard that lies atthe canteen I decided from the outset that I wanted to take some of the Tessin SchoolStudents' opinions and wishes regarding their own outdoor spaces. I had a workshop witheight students from the arts program with the image orientation in which they had to drawand tell them what they wanted to do in the courtyard. The outcome of the workshop, Iused to move forward in my future work with a concept that fit into the environment, wethen apply it in my final design proposal.

Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.
