Magnesium is one of the most important minerals in the body and it participates in many essential processes, such as energy metabolism and protein synthezis. Magnesium deficiency in cattle may occur when they are let out for pasture in the spring, and is associated with tetany, known as grass staggers. A high yielding dairy cow often loses more magnesium daily in the milk than she has available in the body, and magnesium thereby needs to be provided in the feed to prevent the cow from being affected by deficiency symptoms. The uptake of magnesium is mainly located to the rumen and is not regulated by hormones. The surplus is excreted in the urine by the kidneys.

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Building with volume element is relatively new and has started to increase more and more. The regulations that exist to regulate and determine how the transports of volume elements are to be conducted are diffuse and not very well adjusted to address the issues with transporting volume elements. Today there are a number of instances that a company has to turn to in order to get a somewhat different view, what regulations say and interpret it in order to know what applies and not applies regarding the transportation of volume elements. regulations. The rules that are in place make it tough for the volume element producing companies to develop and continue to be active on the market.

Mödravården i Östergötland har påbörjat ett projekt där de vill ta fram en interaktiv webbportal för sina patienter, blivande föräldrar. Denna portal ska fungera som en trovärdig, officiell och bra informationskälla under graviditet. Examensarbetet har som syfte att ta fram ett utseende för denna webbportal, som tilltalar målgruppen samt underlättar interaktionen.För att hitta inspiration till ett bra utseende har en genreanalys genomförts. Detta är en metod som kan användas för att finna inspiration vid skapandet av webbplatser och användargränssnitt. Metoden går ut på att analysera konkurrenter, förebilder,inom en särskild genre.

Det har sedan lång tid tillbaka funnits en löneskillnad mellan den privata och offentliga sektorn, där den offentliga sektorn har befunnit sig på en lägre lönenivå. Denna skillnad är något som faller sig naturligt och som medarbetarna har lärt sig acceptera. Vad är det då som gör att medarbetarna börjar jobba inom offentlig sektor och vad är det som gör dem motiverade till att stanna kvar när det finns en tydlig skillnad i löneutvecklingen. När då gränszonen nås och de monetära medlen inte är disponibla kan det då finnas andra element som kan fungera som kompensation för att motivera medarbetarna.Syftet med denna uppsats är att undersöka om det finns en växelverkan mellan inre och yttre motivationsfaktorer. Samt om det är möjligt att upprätthålla en tillräckligt hög motivation med hjälp av inre motivationsfaktorer för att kompensera avsaknaden av yttre motivationsfaktorer.

This Master?s Thesis aims to investigate and assess the methods used to decrease the discharge ofmetals, primarily copper, from the water purification plant at Assa Industries plating factory inEskilstuna.Literature studies of the purification methods precipitation, ion exchange, evaporation, reverseosmosis and electrolysis has been done to appraise the adequacy of the technique. Thesetechniques are commonly used for purification of industrial waste water.Assa has four plating lines: the Trumline, the big Zinkline, the new Zinkline and the Decorativeline. The new Zinkline is the most modern of the four lines and purification is done byrecirculation over an ion exchange unit. The demand for fresh water is thereby heavily reduced.The Trumline, the big Zinkline and the Decorative line all use older techniques.

The purpose of my empirical study is to see if and how teachers meet the students needs of physical activities in the daily work in the classroom. I also want to explore how different teachers see the connection between the concepts: physical activity and learning. To fulfill the purpose, I have chosen to ask four questions that I will work on in my study.How much and what type of physical activities do the students do in a typical day at school?What happens with the students when they have had a moment of physical activities in the classroom?Do the teachers see any connection between the physical activity and the pupils' ability to concentrate?How do teachers look upon the relationship between physical activity and learning?To get answers to my questions, I have observed and interviewed five teachers. I have compiled and analyzed the results.

Background: As a part of a national health control program, Statens VeterinärmedicinskaAnstalt performs diagnostics to screen flocks for certain pathogens causing high mortality,morbidity and/or serious economical losses. There are several viruses in the programincluding IBDV (infectious bursal disease virus), IBV (infectious bronchitis virus) and NDV(Newcastle disease virus). Method: 96 serum samples were collected from different poultryflocks in Sweden and analyzed by ELISA, which are currently used in the health controlprogram as well as by a commercial prototype of a multiplex immunoassay manufactured byLuminex Corp., which is currently under evaluation at the United States Department ofAgriculture USDA. This 4-plex assay detects antibodies for the three above-mentionedviruses as well as antibodies of avian reovirus. In the context of this study the ELISAs run inroutine diagnostics as well as a REO ELISA were used as the standard for comparison.Result: The antibody concentration in serum from vaccinated chickens was high while theantibody concentration level in serum from not vaccinated chickens was low.

Vilka religiösa symboler, idéer och element kommer till uttryck i filmen Pocahontas? Så lyder problemformuleringen i denna uppsats.Med hjälp av fenomenografi som forskningsmetod, som resulterat i ett strukturerat kategorisystem har jag svarat på denna problemformulering.Filmen innehåller många olika religiösa symboler, idéer och element. Många som man inte ens tänker på om man inte studerar filmen från en religionsvetenskaplig utgångspunkt. Dessa har jag valt att lyfta fram genom denna filmanalys.Nyckelord: Filmanalys, film, religionsvetenskap, mytologi, symboler och tecken..

A piezoelectric injector was modeled, in this Master Thesis Project which was carried out at Scania CV AB in Södertälje, in GT-Fuel. GT-Fuel is simulation program from Gamma Technology.The simulation model for the piezo injector was divided into a hydro-mechanical system and an electrical system (Piezoelectric element). First the hydro-mechanic model was duplicated from Advance Continuous Simulation Language model (ACSL). The simulation results were then compared to the ACSL, to verify that the hydro-mechanical system was modeled correctly. The simulation results for the electrical model were also compared with a Simulink model.

Wastewater contains biodegradable materials, which are often measured as BOD7.Trickling filters are sometimes used as a purification step for BOD-reduction. Atrickling filter is a tower, which is filled with a carrier material. Microorganisms growon the carrier material in the form of a biofilm. This biofilm consists mostly of bacteriathat purify water from BOD.In Älgarås? wastewater treatment plant the water is purified by a trickling filter.However the treatment plant has difficulties reaching the emission requirements forBOD.

Syftet med uppsatsen är att undersöka snickarglädje i den valda byn Hörda. Genom kvantitativa studier diskuteras hur byns fasaderförändrats över tid samt mer kvalitativa analyser av ett litet antal hus idag. Undersökningar av kataloghus bidrar till en diskussion om hur dagens syn på snickarglädje är vilket även representeras ibyns olika typer av hus. Resultatet av de olika undersökningar som gjorts visar att snickarglädjen har betydelse för byborna. Sedan Funktionalismens genombrott i samhället var länge dekorativa element "förbjudna" på hus men har idag återkommit och återigen smyckkar våra hem.
