There is an uncertainty in the market for grain forcing the meat/milk producers to review alternative feeds to a larger extent, in order to get control over the feed costs. This has led to that the meat/milk producers need to have a good knowledge regarding how the different feeds influences the animals and which technical equipment to use for handling. For those that produce their own feedmix, there is a need to put interest in new crops and their characteristics to be able to get the knowledge of what is required for their own production. It is beneficial to keep an open dialogue with advisors to be updated in new crops and new technology for feeding. When mixing feed at farm level, the legislation is not very clear since it the target group is large scale mixing plants. We have brought up the most important rules and regulations from the EU parliament Council as well as the ones from the Swedish Board of Agriculture (SJV), regarding feed mixing on farm and factory level. We have studied beans and pea at two different moisture levels, in order to evaluate how the moisture level affects the distribution of particles when milling with a plaitmill and a hammermill.

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

Storage of biomass is associated with problems like heat development, biomasslosses, and reduction of the fuel quality. Certain processes such as biological- andchemical degradation are responsible for these storage problems. This master?sthesis was carried out at Vattenfall Research and Development AB and is alignedtowards quantifying the biomass losses from short-term storage (1-2 months) ofbark and recovered wood. The biomass was stored in outdoor piles during differentseasons, campaign 1 (summer) and campaign 2 (autumn).

During the 1990?s a large number of building projects were revealed where lack of moistsafety precautions during the construction process had led to extensive moisture damage. Alsoresent implemented studies have shown that the problems with moisture damages have ratherincreased than decreased during the past few years. Moist is considered to be one of the mainfactors to cause unhealth due to deficiencies in the indoor-environment and does also causeunnecessary expenses and a reduction of the confidence in the construction industry.In this Bachelor of Science thesis three projects have been reviewed to examine how moistsafetyhas been observed during the construction process. Main focus has been to identify thebuilding components that are the most exposed to moist, and to examine how they have beentaken into account during the period of design and construction.

Lining techniques such as nap bonding and mist lining were developed in the late 20th century and have gained popularity alongside with the increased use of acrylic emulsions as adhesives. The ability of the adhesive to create a nap bond to the canvases without penetrating the fibers has shown advantages regarding reversibility. In addition, the use of moisture, heat and pressure is reduced, which can be advantageous for more sensitive paintings. These lining techniques have been included in several studies where reversibility, minimal intervention and respect for the individual requirements and problems of each object have been the focus. The adaptability of the methods has been confirmed and to further explore the adaptability, this study consists of three simpler application techniques with the adhesive Lascaux 303 HV on mockups.

The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.

Syftet med detta examensarbete är att studera hur addition och subtraktion introduceras i årskurs ett. Fokuset kommer att ligga på läroböckerna. I studien kommer det att undersökas hur läroböcker väljer att introducera addition och subtraktion samt hur lärare väljer att förhålla sig till dessa läroböcker och hur de använder sig av dem i undervisningen av addition och subtraktion. De valda metoderna för att undersöka detta syfte är samtalsintervjuundersökningar och kvalitativ textanalys. Fyra stycken lärare har blivit intervjuade och utifrån dem har tre läroböcker valts ut till analys.

Addition to the Skellefteå Kraft headquarters: The main part of this thesis is constituted by the work I carried out as project architect for the addition to the Skellefteå Kraft headquarters during the years 2005-2009. The work is presented in the form of a selection of drawings..

Syftet med vår studie är att upptäcka vilka lösningsstrategier som elever i år två använder sig av vid tiotalsövergångar i addition och subtraktion och hur effektiva dessa är. Vi har valt att använda oss av kvalitativa intervjuer som datainsamlingsmetod. Vi har intervjuat 15 elever från tre olika skolor. Eleverna fick lösa 20 uppgifter, tio inom addition och tio inom subtraktion, av ökande svårighetsgrad. Av dessa 20 är tolv uppgifter beräkningar över tiotalsgränser.

Att ha automatiserat grundläggande additionskombinationer i talområdet 0-20 kan underlätta elevers vidare matematikutveckling. I detta utvecklingsarbete undersöktes om ett interventionsprogram bestående av strategidiskussioner, kombinationsträning samt minuttest i årskurs 7 var effektivare än enbart minuttest. Vidare analyserades om ökad säkerhet med additionskombinationerna 0-20 ledde till en generalisering till addition inom talområdet 20-99 samt till subtraktionskombinationer inom talområdet 0-20.En mixed ANOVA med enkla kontraster genomfördes och resultatet visade att interventionsgruppen utvecklades något bättre än jämförelsegruppen under interventionsperioden fram till eftertestet i addition 0-20 men det fanns ingen statistiskt signifikant skillnad mellan grupperna för hela testperioden. Generalisering skedde till addition 20-99 för båda grupperna men interventionsgruppen utvecklades bättre än jämförelsegruppen i subtraktion 0-20. En slutsats är att det är en fördel för eleverna att bli säkrare på de grundläggande additionskombinationerna då de även blir säkrare på addition inom talområdet 20-99 och med träning även säkrare på subtraktion inom talområdet 0-20.

The number of people of getting allergic symptoms is increasing and the reasons are considered to be many. The human have changed their habits and spend more time indoor. In combination with new building technologies where denser housing constructions and new materials this causes bad indoor climate contributes to a higher occurrence of allergiesThere are several courses of action to deal with this problem. One action is by choosing allergy-free interior surface materials. An allergy-free material emits low concentrations of harmful substances resulting in a great indoor air quality.

Between 1965 and 1974, the Swedish Parliament decided to build one million dwellings, called Million Program. The million program buildings were erected with new, untried design solutions, in a short range of time, and at low cost. The residential buildings from that time are now greatly in need of renovation. The municipal housing company, Gavlega?rdarna, renovates and improves the energy efficiency at some of it?s apartment buildings in the district Sa?tra, Ga?vle.

Syftet med denna studie har varit att undersöka och jämföra vilka metoder inom addition och subtraktion som förekommer i två matematiklärobokserier. Vi har sökt svar på frågorna: vilka metoder för addition och subtraktion som läroböckerna ger, hur dessa behandlas och bygger vidare på varandra samt hur böckerna förhåller sig till gällande läro- och kursplaner.Den metod vi har använt oss av är en innehållslig idéanalys, eftersom vi tittat på dels vad, men också hur det tas upp. Materialet vi använt denna metod på är två matematiklärobokserier, som är reviderade till gällande läroplan, Lgr11. Som verktyg för att genomföra denna studie har vi utarbetat ett analysschema som har fokuserat på vilka metoder böckerna tar upp samt tre metaforer som beskriver hur det tas upp.Resultatet av denna studie har visat att det finns stora skillnader på hur böckerna arbetar med addition och subtraktion. Den ena boken tar upp metoderna flera gånger, börjar grundande och bygger vidare för att fördjupa och utveckla kunskaper.

This thesis deals with different methods for measuring moisture-related dimensional changes ofwood. Typically relative humidity is measured to determine if the ambient climate around anobject is harmful to it or not. Values between 40 to 65% RH are recommended for hygroscopicmaterials. To know how a wooden object actually reacts to changes in the surroundingenvironment requires methods that involve the object itself. Because of the wood anisotropy,differences in wood structure, finishes and other restraints, it is not always possible to predict themovements.This paper addresses various measurement methods, primarily methods that have been testedin the field of conservation, with examples of their use.
