The water level of Lake Mälaren has been regulated since the 1940?s. A recentinvestigation suggests that the current regulation needs to be adjusted in order toprevent a decline in water level, salt water from infiltrating from Lake Saltsjön,and risk of floodings. In addition to these preventions, the new regulation couldpotentially effect the natural environment and agriculture practices in the lowlands that surround the lake. The new regulation proposal calls for an increase invariations in Mälaren?s water level during seasons, while the annual mean waterlevel will remain the same.

Epizootier som drabbat marina däggdjur och lett till storskaliga dödsfall har uppmärksammats runt om i världen de senaste decennierna. Höga halter av persistenta miljökontaminanter såsom DDT (diklordifenyltrikloretan) och PCB (polyklorerade bifenyler) har uppmätts hos djur som drabbats. Detta har lett till tankar om att miljökontaminanter, i den nivå de finns i våra akvatiska ekosystem idag, kan vara en bidragande orsak till den ökade mottagligheten för infektioner och den ökade mortaliteten hos marina däggdjur. I denna litteraturstudie sammanställs resultaten från försök, både på laboratoriedjur och marina däggdjur, som tyder på att kontaminanter med fokus på PCB kan orsaka immunosuppression och därmed vara en bakomliggande orsak till allvarligheten i dessa epizootier. Resultat från studier visar på att PCB kan orsaka immunosuppression genom att ge nedsatt proliferativt svar hos T-lymfocyter under stimulering med mitogener, minskad aktivitet hos NK-celler, nedsatt antikroppsproduktion, minskad antigen-specifik proliferation och minskat DTH (delayed-type hypersensitivity) svar.

The design regulations of Boverket (BKR) have long been the mandatory standard for construction design in Sweden. However from the end of the year 2010, the BKR will be replaced by the European standard Eurocode (EC). The transition to EC has been delayed and it is not until the second of May 2011 that the use of EC will be mandatory. Because EC and BKR differ from each other it is highly interesting to investigate and explain these differences.The purpose of the thesis is to compare the two standards and investigate how they give different results or not for the dimensioning of structures of steel with associated loads. The current project HVC (Pets Science Center) in Uppsala is used as a model for the design of the steel structure used in this study.

Abstract Moerkerken, Anneke (2006) Klassrumsmanagement, Fördröjd uppmärksamhet med hjälp av trafikljusmodellen Skolutveckling och ledarskap, Specialpedagogisk påbyggnadsutbildning, Lärarutbildningen, Malmö högskola Syftet med följande arbete är att bidra med en utökad insikt om begreppet klassrumsmanagement och dess begreppsstrukturer samt att undersöka användandet av trafikljusmodellen med betoning på det specialpedagogiska området. Klassrumsmanagement berör hanteringen av mål och innehåll samt genomförande av lektioner i ett socialt organiserat sammanhang i klassrumsmiljöer. Man kan med hjälp av dess teorier arbeta med de organisatoriska, sociala, didaktiska och pedagogiska färdigheter som behövs för att på ett bra sätt kommunicera med eleverna. Detta för att skapa förutsättningar för ett klassrumsklimat i vilket att lära ut och att lära in sker så effektivt, positivt och innehållsrikt som möjligt. Vid trafikljusmodellen använder man sig av olika signaler för när eleverna kan rådfråga pedagogen eller sina klasskompisar medan de arbetar självständigt med sina uppgifter. En enkät angående användandet av trafikljusmodellen var överlag positiv. Både pedagoger och elever upplevde att fördelningen av den tid pedagogerna förlade på eleverna blev mera rättvis och att eleverna kunde koncentrera sig bättre på uppgifterna.

The degree project is performed at Metso Kamfab. The production is aimed on machines everything from handling of fiber to paper pulp. Metso Fiber and Kamfab are using Pro/Engineer for design and blueprint production. The processing department types the NC-programs in notepad on the basis of the blueprints, the CAD-dates that already is there are not used. The aim with the work is to study if Kamfab can use CAM-system for processing and production of programs for their NC-machines.

This master thesis was done for a company called BRUKS which is active in woodprocessing,bio-energy and bulk material handling industry. The idea for the master thesis wasto develop a new reclaiming method for silos where wood chips are being stored. A mediumsegment of between 1000 ? 5000 m3was defined as the segment with the most sales potential.Two different concepts were produced, one for new constructions and one for rebuildingalready existing silos.In the beginning of the master thesis a lot of time was spent on visiting different BRUKSoffices and customers to get an overview of the industry and the product. This informationwas the basis when the idea generating phase began.

SammanfattningMiFID, direktiv om marknader för finansiella instrument är ett nytt europeiskt regelverk för den finansiella sektorn som träder i kraft den 1: a november 2007. Direktivet syftar till att förstärka konkurrenskraften för den finansiella sektorn, förbättra konsumentskyddet samt inkludera hela utbudet av finansiella tjänster och produkter. Då MiFID: s införlivande i svenska lag försenades fick de svenska värdepappersföretagen under 2007 en relativt kort tidsperiod på sig att anpassa sina verksamheter till de nya bestämmelserna. Syftet med denna uppsats är att undersöka vilka svårigheter tre svenska värdepappersföretag erfarit vid arbetet med att anpassa deras verksamheter till de nya bestämmelserna i MiFID. Vi har studerat direktivet och jämfört med nuvarande regleringar samt genomfört fyra intervjuer, varav tre med svenska värdepappersföretag av varierande storlek.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Cow?s milk and chronic constipation in children ? A systematic reviewAuthor: Sara Palm & Anna SvenssonSupervisor: Frode SlindeExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 27, 2014Background: Chronic functional constipation is common among children. Up to a third of all who seek a paediatrician suffer from constipation and it is a widespread problem for children in many countries. Lately it has been discussed if cow?s milk can be a cause of the constipation and if it should be considered a delayed hypersensitivity.Objective: The aim of this systematic review is to examine whether there is scientific evidence to recommend a cow?s milk-free diet as a potential treatment in chronically constipated children.Search strategy: The literature searches were performed in the databases Pubmed, Scopus and the Cochrane library, using the search terms cow?s milk, constipation, milk proteins, dairy products, milk hypersensitivity, cow milk and cows milk between March 17th and April 4th 2014.Selection criteria: Randomized controlled trials measuring stool frequency in chronically constipated children on a cow?s milk-free diet were included.

To get a good economy on the dairy farms the fertility control of heifers and cows is a crucial factor. It is also important to know which key parameters that should be tracked. In this work well established routines for heat detection have to be applied. When the dairy farmers use technical aid in estrus control it is important not to forget that technical aids can not replace the human eye. Approximately 50 % of all opportunities to inseminate are missed because clear signs of estrus have not been displayed and/or recorded. The cattle fertility has been declining over recent years. During the same time the cow?s proceeds have increased, consequently applying a higher pressure on the cow and the manager.

The castration of piglets is performed routinely all around the world. Most castrations are done without anaesthesia and analgesia, despite the fact that this procedure has been proved to induce acute pain and stress for the piglets. The procedure regarding castration of piglets is currently a hot topic of debate and an important political issue. The underlying issue is the boar taint which are highlighted in the heating of the meat after slaughter, which in turn can lead to reduced meat sales as it can be perceived as unpleasant for many consumers. The purpose of this study is to examine alternative drugs which may be selected in order to replace the practice of castration of piglets without anaesthesia, in light of improved animal welfare.

Many buildings are now nearing the end of their service life. This applies to both the older houses from the 40's and 50's to the million project houses that did not prove to be as sustainable in the long run. Often there is a desire to extend the service lifetime, but to do that you need to make detailed inspections. The Folkets hus in Gävle is one of those buildings that is in need of renovation and to fulfill the new requirements that must be met in today's buildings. It is desired to make the buildings rentable space more attractive and to extend the building with two more floors.

This thesis is performed at Saab Bofors Dynamics in Karlskoga and investigates a technique for ranging with laser pulses. The investigated technique is called Constant Fraction Detection (CFD). Described briefly, the received laser pulse is split into two equal parts, where one part is delayed half the pulse width and inverted. This signal is added to the original pulse. The resulting curve has the shape of a laying S and the detection of the zero level is used to stop the time measurement.

The economic conditions for Swedish dairy farmers are constantly changing. The numbers of producers are declining and the economic conditions for dairy production are weakening debilitating. To improve the economic situation for a farm a hired contractor is a possible solution since previous studies show that machinery cooperation may be beneficial for the farmers. The aim of this study is to examine the possibility for farmers to cut costs by hiring a contractor for harvesting silage. A comparison between using own machinery and hire a contractor is the starting point of this study. Another aim is to discuss the farmer?s decision process when achieving today?s situation and to determinate what factors affect their decisions. The study is based on cases selected from four farms that today have chosen not to or only to some extent, hire a contractor for harvesting silage.

Examensarbete utfört på uppdrag av Boliden Mineral AB i Aitikgruvan. Det har sin bakgrund i att malbarheten hos Aitikmalmen varierar kraftigt, upp till 40 %. Detta försvårar planeringsarbetet och således mycket intressant och lönsamt att söka orsakerna till variationen. Examensarbetet syftar således att utgöra en förbättring i verksamheten helt i linje med styrdokumentet, the new Boliden way. Emellertid föreligger stora svårigheter med att spåra malmen genom hela processen varför man i detta arbete har valt att studera sambandet mellan krossbarheten och bergmassans respons på den tillförda specifika energin från borriggen.

Optimization of soil tillage and crop rotation is important in many aspects, but particularly in maximizing profit margins. Since the economic outcome is usually decisive, it can be interesting to study different combinations of soil tillage systems and crop rotations in order to identify the maximum economic outcome. How a crop functions in a particular tillage system determines whether it is profitable to grow that crop. Different tillage systems affect the soil and its processes in different ways. Reduced tillage often works best on weak-structured heavy clays and on silty clays.
