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..

I denna uppsats betraktas två olika bandspridningstekniker och vilken påverkan de har på telekrigsförmågan. Uppsatsen svarar på frågan:Vilka möjligheter finns att bedriva signalspaning och störning mot radiokommunikation som använder bandspridningsteknikerna frekvenshopp eller direktsekvens?Inledningsvis beskrivs en modell för telekrig mot radiokommunikation, ?telekrigcykeln?. Därefter beskrivs principer för ett radiosystem samt de två bandspridningsteknikerna frekvenshopp och direktsekvens. Slutligen analyseras bandspridningsteknikernas påverkan med hjälp av telekrigcykeln och resultaten diskuteras.Uppsatsen kommer fram till att båda signalerna går att spana mot, direktsekvens innebär större svårigheter för signalspaningen än frekvenshopp.

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.

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.

En av Glimek AB:s mest förekommande maskiner är SD-180 som används för degavvägning. Den finns i flera olika varianter. Den enklaste har enbart start- och stoppknapp och en potentiometer för att ställa hastigheten och en mer avancerad variant har en operatörspanel där olika möjligheter till inställningar finns.Konstruktionen på denna maskin hade inte uppdaterats på många år och behövde en uppdatering av användargränssnitt, programvara och elkonstruktion. Arbetet har framförallt koncentrerat sig på användargränssnittet till panelen.En del av arbetet var att undersöka om det var möjligt att utesluta PLC ur konstruktionen och använda en mer avancerad programmerbar frekvensomformare. Eftersom det blev problem med lanseringen av programvara till frekvensomformaren och enbart en mindre bra fungerande demoversion fanns tillgänglig så var detta tyvärr inte möjligt.I arbetet har olika varianter på operatörspaneler utretts.

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.

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.

Arbetet bygger på att de informationssystem som används idag men som blir allt äldre och därigenom inte klarar de krav som ställs på dem. Detta medför att informationssystemen måste migreras till modernare plattformar, då företagen dels inte klarar sig utan dess nuvarande funktionalitet och dels måste vidareutveckla systemen.Detta arbete tar upp olika sätt som detta kan genomföras på och vilka problem som kan komma att uppstå när detta sker. För att kunna undersöka detta så genomfördes ett antal migrationer. Språken som migrationen kommer att ske mellan är Visual Basic 6 och Visual Basic .net. Migrationerna kommer att ske med hjälp av ett migrationsverktyg, samt ett ramverk som i arbetet skräddarsys för just arbetets typ av migrationer.Det arbetet kommer fram till är att det sker problem vid användande av ett verktyg och även att det inte ger tillräckligt med respons på vad som gått snett under migrationerna..

At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received.

The aim of the thesis was to investigate energy consumption and carbon dioxide emissions from an advertisement broadcasted on the radio or the television or distributed through press. The object was to calculate the amount of carbon dioxide emissions per individual receiver of an advertisement in Sweden. There was no room for a deeper investigation into editorial work within the framework of the thesis. Consequently, main focus of the radio and television study was on broadcasting itself and the components involved. Focus for the press study was on paper production, printing and distribution. Production and discarding of media equipment was not taken into account.

In the year of 2001, China launched their new international marketing strategy Going Global. As an effect of this, the frequency of Chinese establishments in Sweden has increased heavily in the last ten years. One of the larger Chinese establishments in Sweden happened in 2003, by the telecom company Huawei. This essay illustrates the obstacles that a Chinese company faces when setting up their business on the Swedish market. Previous studies have focused on Swedish establishment abroad.

Denna uppsats bygger på ett projekt med syfte att öka företags konkurrenskraft genom att formera grupper, där kontaktytorna mellan företag sinsemellan samt mellan företag och universitet skall utökas och därmed ge utbyte av viktiga erfarenheter. Uppsatsen beskriver fem småföretag som producerar livsmedel och har arbetat i en innovationscirkel med ovanstående syfte. Dessa fem företag, Nordupplandsgruppen, har identifierat ett gemensamt intresse under dessa innovationscirkelträffar, nämligen att genom samverkan lösa det avsättningsproblem som finns hos företagen. Syftet med uppsatsen är att utreda företagens möjligheter att lösa detta problem genom att samverka inom marknadsföring och försäljning. Företagens problem med att få avsättning för sina produkter med bättre lönsamhet har visat sig vara en följd av resurskrävande distribution. Företagen har höga externa transaktionskostnader, det vill säga resurskrävande transaktioner för att sköta kundkontakter, söka nya kunder, presentera produkter, planera transporter och göra uppföljningar i butiker.

As to now, no study has been made of the mica tempered pottery found along side the asbestos tempered pottery in Norrland during the Bronze Age and Early Iron Age. Its occurrence has previously only briefly been noted in a few published works and the dating and geographical distribution of mica tempered pottery in the north of Sweden has to a large extent been unknown. This paper aims to compile the available information about this type of pottery and the locations where it has been discovered in order to date and explain the occurrence of mica tempered pottery in Norrland. It's also suggested that the occurrence of mica tempered pottery is connected to the spread of the early metalwork from the east to areas that today makes up the north of Norrland..
