In 2003 the recommended phosphorus allowance for dairy cows in Sweden was lowered approximately 10 %. For a cow at a production level of 35 kg ECM it decreased from 0,40 to 0,36 % of dry matter. To investigate if the decrease has been implemented at farm level, analysis of following minerals; P, Ca, Mg, K, Na, S, Se, Cu, Mn and Zn was performed on the TMR at 20 farms in Sweden in the summer of 2004. The purpose was to describe the actual allowance of different minerals as compared to the new recommendations. One hypothesis was that the decrease in recommended allowance of phosphorus would lead to the need of new mineral feeds on the market.

Effects of fishery closure on perch was detected as female perch was on average 5 cm longer in closed areas compared to non-closed areas. This could be a result of larger individuals surviving as an effect of reduced fishing. No effect was detected on the reproduction rate of YOY (young of the year) perch.A zooplankton survey revealed less amounts of the most important plankton groups for YOY perch in areas with failed reproduction, though the difference was statistically insignificant.The distribution of YOY perch and YOY/adult stickleback differed completely in this study with no area where the two species are both present. It is sketchy to draw any conclusions from this data but it remains a field for further investigation.The reproduction problem is concentrated to the outer parts of the archipelago which confirms previous studies of the geographic extension..

Background: Following an increased awareness concerning social and environmental aspectsin society, more enterprises establish sustainability reports in order to inform theirstakeholders about the company?s sustainability duties. A previous study indicates that themetal sector is enjoying relatively limited increases in business opportunities and/or financialvalue of corporate responsibility. Another study suggests that there is a gap in expectationsbetween producers and users of sustainability reports due to an uncertainty regarding whatinformation such reports should contain and what audience such reports should target. Thequestion is whether or not a gap in expectations concerning sustainability reporting is acontributing factor to the limited increases in financial value in the metal sector?Purpose: The purpose of the study was to examine how a sustainability report should becarried out by a company in the steel industry given what information the company and thestakeholders consider as essential in a sustainability report.Methodology: To accomplish the purpose of the study, a deductive approach was used due tothe availability of suitable theories.

This report has a dual focus. The first goal was to increase the knowledge of how the use of electricity in a residential building is distributed. Electricity in residential buildings is used for lighting in common areas, elevators, pumps and many other appliances. The electricity used for these different parts is to a great extent unknown. A few studies have been carried out and the result of these is referred to in this report.By means of measurements and approximations the use of electricity for various appliances became known.

Swedens membership in the European Union have resulted in an internationalcharacterized labour market. The construction sector is the area who employs mostposted workers among the 7400 employees who monthly enters the market. It?s alsothe sector where a big part of the work-related deaths occurs. The purpose of this studyis therefore to contribute to a greater understanding of the regulation regarding postedworkers, their work environment and the consequences of it.

The Swedish commercial real estate market is in the current situation globally affected and is actively interacting with the rental and capital markets through international tenants and investors who are setting new demands on the property owners. The European Union has set new requirements as well in purpose of reducing humanity?s negative effect on the climate and therefore the international real estate market has introduced Green Building-certificates in order to decrease the real estate industry?s environmental impact.Certificated buildings with low energy consumption are a more common sight in Sweden these days. The development, however, could go even faster if there was not certain difficulties between property owners and tenants. Previous research has revealed that tenants do not always have knowledge about, or may have access to the economic benefits that a green building can provide.

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

Syfte: Idag förväntar sig allt fler kunder och anställda att företag ska ta stort ansvar i samhället och inte bara generera vinst och säkra jobben för sina anställda . Detta samhällsansvar kallas ofta för CSR (Corporate Social Responsibility) även på svenska men ofta är ett mer relevant begrepp ?samhällsansvar? eller ?socialt ansvar?.? Vi vill ta reda på varför och hur företag arbetar med CSR.? Syftet med vår undersökning är att få en djupare förståelse för vad CSR är.? Vad CSR har för betydelser för företag i dagens samhälle.? Vad CSR får för påverkan på företagens bild utåt sett och dess ekonomiska vinning på grund av att ta socialt ansvar.Metod: Vi har använt oss av hermeneutikens förhållningssätt där tolkning står för huvudsaken i studien. En blandning av induktiv och deduktiv ansats har använts och undersökningen bygger på en kvalitativ metod med intervju som grund. Vi beskriver även arbetets validitet och reliabilitet.Resultat & slutsats: Vi anser att vi genom denna undersökning fått en djupare och bredare bild av vad CSR är och vad den har för betydelse för dagens samhälle och dess affärsverksamhet.

Sitka spruce (Picea sitchensis) is a tree species that have its natural distribution along the West Coast of North America, from Alaska in the north to northern California in the south. Sitka spruce is a typical coastal tree species that can reach heights up to 85 meters and occurs in single pure as well as in mixed stands. The main purposes of this study were to describe the Sitka spruce growing characteristics and the volume production in comparison to spruce (Picea abies). The possibility to predict future volume production by using prognosis tools designed to be used on spruce were also studied. The material that has been used in this study are permanent sitka trials established by the Faculty of Forestry fixed Sitka trials and also material gathered in this study. A literature study was also carried out in order to determine the Sitka spruce growing characteristics. Sitka spruce has a high adaptation and a high volume production on a broad scale of soil types. The tree species is a pioneer species that has a fast early growth and in combination with sharp needles it is less susceptible to animal browsing than spruce. The factor that is the single most limiting factor for where the Sitka spruce can be planted is frost. This factor can be limited by using plant material with a well-suited provenance. According to the literature, the Sitka spruce has an average total volume production that is between 20-40% higher than spruce.

Corporate social responsibility, CSR väcker intresse bland företag och även många forskare har uppmärksammat begreppet på senare tid. Det finns banker som har börjat ta hänsyn till CSR i låneprocessen. Däremot är den forskning som finns om hur ett företags arbete med CSR beaktas i låneprocessen begränsad, vilket gör det svårt att skapa en förståelse för området. För att kunna skapa en bättre förståelse har det resulterat i frågeställningen: Hur och varför beaktar banker företagens arbete med CSR vid kreditgivning? För att besvara frågeställningen har CSR definierats med sju dimensioner vilka har varit utgångspunkterna för den teoretiska referensramen, samt för den kvalitativa studien.

Playing chamber music is not only about music - there are social and practical things to deal with too. For example things like how to decide practising times and how to share the responsibility of the practical things like finding score for the music and booking rooms for the rehearsals. And also how to choose a way to interpret a piece when members of the ensemble are having several different opinions about it, what kind of roles people in the ensemble take and how these roles work with each other. This is an essay about what I have learned about these things on the different lessons and lectures, from all conversations with my fellow students and teachers and from my own experience as a member of different ensembles during my studies in the University of Gothenburg..

Detta examensarbete är utfört på Helsingborgs Dagblad AB i Helsingborg. Examensarbetet omfattar en analys ur kvalitetssynpunkt av HD:s material-, energi- och transportflöden, dess påverkan på miljön, kopplingen mellan HD:s tre kärnvärden och vikten av ett strukturerat miljöarbete samt ett antal förslag på fortsatt arbete. HD:s materialflöden består främst av material för tryckningen men även en hel del elektroniska apparater. Ett stort antal datorer och annan kontors-utrustning står på dygnet runt, året runt vilket orsakar onödigt stor energiförbrukning. HD:s verksamhet är beroende av transporter, både av material och personer.

CSR, Corporate Social Responsibility, har under de senaste decennierna utvecklats till en mer eller mindre obligatorisk del i ett företags verksamhet i dess strävan att lyckas överleva på den konkurrensutsatta marknaden. Det finns dock än idag stora skillnader i hur pass mycket olika företag ägnar sig åt CSR. Med utgångspunkt från en rad olika skandaler som media belyst de senaste två decennierna, och hur allmänheten reagerat på detta beroende på vilket företag det varit fråga om, har ett intresse väckts i varför vissa företag lägger mer resurser på CSR-arbete än andra.Denna studie ämnar undersöka huruvida det förekommer skillnader mellan industri- och konsumentföretags grad av CSR-arbete, och i så fall - mer specifikt - om dessa skillnader har att göra med om det är ett industri- eller konsumentföretag, eller om det endast är andra faktorer som spelar in. Studien bygger på en kvalitativ undersökning där två företag från respektive bransch undersöks på djupet, och kompletteras med en kvantitativ undersökning där hållbarhetsredovisningar samt webbsidor från ytterligare tre företag från respektive bransch studeras. Utifrån tidigare forskning samt det teoretiska ramverket som framtagits, genereras tre hypoteser där förväntningar på utfallet presenteras och testas.Undersökningen visar att det förekommer skillnader mellan valda företags CSR-arbete, inte bara mellan branscherna utan även inom dem.
