Kemisk stabilisering av gruvavfall från Ljusnarsbergsfältet med mesakalk och avloppsslam : Chemical stabilization of mine waste with sewage sludge and calcium carbonate residues
Chemical stabilization of mine waste from Ljusnarsbergsfältet with sewage sludge and calcium carbonate residuesMine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolvedoxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as complexing agents for heavy metals and in this way increase their mobility.
Pre-treatment of grain for ethanol production during storage
Ethanol for automotive purposes is an issue much debated and researchers disagree about the benefits of bioethanol. Converting energy-rich crops into ethanol suitable as motor fuel is a complex process and continuous development and improvements of processes and material used are important steps in the work of developing environmental friendly fuels. Grain is usually preserved by drying which consumes a lot of energy. Alternative storage of high-moisture grain in airtight storage systems reduce the energy required to produce bioethanol and studies have also shown that ethanol yields are increased more than 10% in ethanol fermentations of moist grain compared to dry. Airtight storage is often not perfectly airtight so biocontrol agents are necessary in order to preserve the grain.
Per oral cancerbehandling: patientens följsamhet till ordination
Användningen av per oral cancerbehandling har ökat de senaste åren. Per oral cancerbehandling är inte automatiskt förknippat med samma strikta riktlinjer som vid intravenös behandling, däremot så är biverkningsprofilen med allvarliga och ibland livshotande tillstånd i stort sett densamma. Forskning har visat att följsamheten till den per orala cancerbehandlingen varierar, ibland är låg och inte är bättre än andra kroniskt sjuka gruppers följsamhet. Patienten sköter till stor del behandlingen själv. Konsekvenserna av detta kan vara ett försämrat behandlingsresultat, risk för över resp.
Det svenska spionaget i Baltikum 1943-1957 : En studie av ett fiasko?
During and after World War II Sweden was spying in the occupied Baltic countries which had been occupied, from 1943 by Nazi Germany and from 1944 by the Soviet Union. It began in 1943, with the Germans still occupying the Baltic countries, when Sweden and its intelligence service ?C-byrån? recruited volunteers among the Baltic refugees in Sweden and sent them back to the countries they had fled from. Many of the Baltic refugees to Sweden were men aged 25-45 so the Swedish intelligence service had a good recruiting source. This started the first period of intelligence operations in the three Baltic countries.

In the present situation a bottleneck occurs at the warehouse loading section, and the consequence is fulfill the time of delivery for all customer orders.
Vägledaren, en förändringsagent? : Ett antal vägledarröster om val kopplade till kön, klass och etnicitet
Uppsatsens syfte är att utröna hur vägledarna bemöter den potentiella rollen som förändringsagent gällande elevers studie ? och yrkesval. Undersökningen genomfördes via kvalitativa intervjuer med fyra verksamma vägledare i grundskolan. Resultaten visar att vägledarna anser att kön, klass och etnicitet utgör tydliga påverkansfaktorer i studie- och yrkesvalet. Könstillhörigheten är i många avseenden avgörande för valet av gymnasieutbildning och den indikerar även mängden av efterfrågan på vägledning.
Behandlingsresultat av kliniska mastiter : en studie av mastitbehandlingar utförda i mjölkkobesättningen på Jälla naturbruksgymnasium 1997-2008
Mastitis is an important disease in dairy cattle. It is very costly for the farmers and affects a large number of animals. Few studies have been made investigating the outcome of treatment for acute clinical mastitis under Swedish conditions, and it can be problematic to use the results in foreign studies since both the microbial flora as well as treatments may be different from the situation in Sweden. In this project we have investigated data on clinical mastitis and antibiotic treatment in the dairy herd at Jällaskolan, Uppsala based on recordings during the last ten years. The material includes both Swedish Red (SRB) and Swedish Holstein (SLB) breeds, which have been kept at the farm under similar conditions.
Accepterat pris : En analys av samarbeten inom fastighetsma?klarbranschen och dess prissa?ttning

This fact inspired to examine similarities and differences of being and not being part of the cooperation and thereafter comment on the outcome.
Etablering i främmande kulturer : En fallstudie över små svenska tekoföretags etablering i Spanien
This bachelor of economics paper discuss that the increasing globalization has put the small companies in the Swedish textile and clothing industry in a situation where internationalization has become a necessity. Furthermore has the European Union lead to that this type of companies has to seek growth on foreign markets with great socio cultural distance from the home country, Sweden. Nowadays there?s no time to internationalize in the same course of action like before. Before, the Swedish companies begun their operations abroad in fairly nearby countries and only gradually penetrated more far-flung markets.
Tredjemanskontroll - Säker rätt är säkert rättssäker : En studie med utgångspunkt i betänkandet Förbudet mot dubbla förfaranden och andra rättssäkerhetsfrågor i skatteförfarandet (SOU 2013:62)
SKV and Tullverket have several important tools and methods available in each activity to ensure that taxes and fees are paid and charged rightfully. Among other things they use tax or customs surcharges, targeted and general third party injunctions or targeted and general third party audits. The targeted controls, ergo targeted injunctions and audits, are targeted towards specific persons or documents while during the general controls these are not specified. The methods have repeatedly been the subject of discussions and attempts to simplify the tax procedure and increase the Rule of Law for the individual.The government appointed a commission on March 8 of the year 2012 with the assignment to prepare proposals to increase the Rule of Law in the tax procedure. The assignment was therefore to analyze the areas of tax and customs injunctions, reimbursement because of expenses and agents and also third party controls.
Survey of regulations concerning pesticides in Sweden and the EU : cultivation techniques and competition aspects for Swedish onion and apple producer
As a member of the EU, Sweden has, in some cases, transferred the controlling rights to the Union. This means that the rules defined by the EU must be followed in all member countries, including Sweden. The European Agricultural policy constitutes the largest part of the EU's
annual budget and is in contrast to many other areas fully funded at EU level. The last decade, many new regulations on chemicals and pesticides have been introduced which brought great changes and a lot of work throughout the Union, including Sweden. Sweden has always had a strict policy on chemicals and has been at the forefront when it comes to sustainable agriculture and environmental management.
På återseende om 20 år? : En studie av HusmanHagbergs relationsmarknadsföring
Svensk titel: På återseende om 20 år?Hur hålls relationen mellan kund och företag vid liv på en sällanköpsmarknad?- en studie av HusmanHagbergs relationsmarknadsföringEngelsk titel: Will we meet again in 20 years?How does the relationship between a customer and company survive on a ?rarely buying market?? ? a study of the relationship marketing of HusmanHagberg Författare: Emma Anderberg och Maria ÖhmanFärdigställd: 2007Handledare: Nazeem Seyed-MohamedAbstract:During recent years a focus on the development of good and long-term relationships with the customers has replaced the single transactions that which have been the goal when using traditional marketing methods. To succeed on a tough and competitive market it is important for companies to develop good and long-term relationship with their customers. Working with relationship marketing within the estate agent market is especially complicated in many ways. An estate agency is a service company and works as a middleman between a buyer and a seller and therefore has a complicated relationship to its costumers.
Kartläggning och nedbrytning av komplexbildare i ett integrerat kartongbruk
Skoghalls Bruk fick i juni 2005 tillstånd av miljödomstolen att öka kartongproduktionen från 665 000 till 800 000 ton kartong per år. Villkoren för tillståndet var att under en prövotidsperiod bl.a. utreda möjligheten att minska utsläpp till omkringliggande vatten.Syftet med examensarbetet var att kartlägga Skoghalls Bruks avloppssystem med avseende på komplexbildarna EDTA (etylendiamintetraättiksyra) och DTPA (dietylentriaminpentaättiksyra), kväve samt fosfor.Dessutom genomfördes nedbrytningsförsök i luftade dammar i laboratorieskala.För att få en klarare bild av nedbrytningen i Skoghalls Bruks luftade damm gjordes även en molekylviktsfraktionering på inkommande och utgående avloppsvatten.Komplexbildare används inom pappers- och massaindustrin för sin förmåga att binda till sig metalljoner som kan vara skadliga i processen. Metalljoner katalyserar nedbrytningen av väteperoxid i blekningen och påskyndar bildandet av aldehyder i kartongen vilket kan leda till lukt- och smakpåverkan.EDTA och DTPA anses vara stabila ämnen, vilket innebär att de är biologiskt svårnedbrytbara. Under den litteraturstudie som genomfördes fanns motsägande uppgifter angående nedbrytningen av komplexbildare, där vissa menade att de genomgår biologisk nedbrytning, men att det sker mycket långsamt.
