Within agriculture it is important to optimize the use of nitrogen, not only from an economic point of view but also to minimize damage to the environment. This can sometimes be difficult, especially within organic farming. Organic farmers are using increasing amounts of waste products from the food industry to cover their nitrogen needs. These different organic fertilizers release nitrogen at different rates and under specific soil conditions. Because of this, it would be beneficial to have a standardized method to measure the amount and rate of nitrogen mineralization from organic fertilizers. This project contributes to this knowledge by investigating whether relatively simple and repeatable laboratory methods can be used to estimate the nitrogen fertilizer value of organic fertilizers.

AbstractThis report intends through a case study to investigate if lightweight concrete isappropriate as main material in the outer wall of a seven storey residential building.A technical design is carried out in accordance with the definitions and requirementsfor passive houses, given by FEBY?s1 ?Demand specification for passive houses?.A literature review is also carried out for a comparison between regular bolt wall andlight weight concrete wall, with a focus on the safety of moisture.The lightweight concrete block used in the report is as a celblock produced by thecompany H+H Sweden AB.The methods used have resulted in compliance with requirements andrecommendations from authorities. Calculations of energy, noise and moisture riskassessment has been carried out.The work has resulted in the conclusion that the lightweight concrete itself is notable to isolate in the extent necessary to obtain chosen U-value of 0,1 W/m2 ° C,without getting to thick. Therefore additional insulation is needed. There are fewrelevant reference objects built with only light weight concrete.

Yom Kippurkriget 1973 kan sägas vara det första sjökriget då sjömålsrobotar nyttjades av krigets respektive parter. Hur påverkade denna teknikutveckling av sjömålsroboten Israels sjötaktiska agerande? Syftet med uppsatsen är att undersöka hur teknikutvecklingen av sjömålsroboten har påverkat Israels sjökrigföring, samt undersöka huruvida det är tekniken som styr taktiken, eller tvärtom. Detta sker med en komparation av israelernas sjökrigföring under två krig, sexdagarskriget 1967 samt Yom Kippurkriget 1973. Analysverktyg för denna jämförelse utgörs av Wayne P.

Background: The result of our interactive information society is that sales business has shifted from a tactical to a strategical focus, thus companies have had to adapt to this change. The evolution of sales shows that companies have gone from one static model to another, which is discarded by the new concept ?insight selling? claiming that it through insights is possible to be forceful in the, these days, rough sales climate.Purpose: The purpose of the report is to form an understanding of how insight sales affect a sales process.Research question: How does insight selling affect the B2B sales process?Methodology: Process mapping through interviews in combination with organizational documents.Findings: Insight selling affects the sales process by a clearer research mindset and a change in communication in relation to the customer..

The EU has for a long time had a special relationship with its former colonies in Africa Caribbean and the Pacific, called the ACP?countries. This relationship is about to change radically with the new partnership agreement signed in June 2000 in Cotonou. This essay aims to study the EU ?ACP Partnership Agreement from the perspectives of two different theories: The liberalist, free-trade policy theory and the nationalist/regionalist, protectionist theory.

The purpose of this thesis is to examine a selection of ideological publishing houses in Sweden today. We want to examine where they are situated in the literary society, their terms and prerequisites. This is achieved through interviews with informants from each of the publishing houses, which we analyze with concepts from the culture sociologist Pierre Bourdieu. The publishing houses are also put in context through information from other actors in the literary field, together with previous research and other material about the Swedish book market. The main research problem in the thesis is to examine the relations between the selected publishing houses ? which profile themselves as ideological ? and the literary field where they exist.

The Russian-Georgian war of 2008 drastically changed Europe´s and Sweden´s political climate.Russiashowed that it is capable of successfully completing complex campaigns including ground, naval and air assets. However, not much has been said about the theoretical framework and doctrine of the Russian military of today. Even less has been researched about Russian use of air power and applied air theory. Are air power assets still considered primarily as support of ground offensives or has the theoretical framework changed?John A.

In this Bachelor Thesis (20 p.), we present the history and development of "Intelligent Houses", and most important- explore some of the future possibilities in this area. The project has been carried out through an interdisciplinary cooperation between three different educations at the Blekinge Institute of Technology. By conducting a dialogue with various actors with different professions, we have been trying to identify needs within the concept of "Intelligent Houses", were the end user is not only the tenant or homeowner. Through Participatory Design methods, such as a Future Workshop, we have brought the users together to discuss their own and each others needs and hindrances in their respective work practice, and how intelligent house technology could improve their work conditions. We have also been testing a highly sophisticated CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally developed for regulating indoor climate systems.

Denna studie behandlar det upplevda innovativa arbetsklimatet hos en projektgrupp vid Eskilstuna Energi och Miljö (EEM). För att studera detta har undersökningsledarna använt sig av kvantitativ och kvalitativ undersökningsmetod. Det i form av en enkätundersökning med fem deltagande personer ur projektgruppen och intervjuer med samma fem personer. Det övergripande syftet är att undersöka hur arbetsklimatet upplevts i en projektgrupp vid EEM. Fokus inom studien ligger på in-novation och gruppklimat.

Syftet med vårt examensarbete är att undersöka hur passivhus eller så kallade nollenergihus skiljer sig i funktion samt uppbyggnad från konventionella hus.I vår undersökning tar vi upp hur utformning, orientering, material samt ett väl fungerande klimatskal påverkar energiförbrukningen.Vi har tittat närmare på faktorer som sparar energi samt hur ett typiskt passivhus är uppbyggt. För att se hur teorin fungerar i praktiken har vi tittat närmare på befintliga passivhus, nämligen de på Oxtorget i Värnamo.Vi har kommit fram till att passivhus fungerar och vi anser det som väldigt viktigt att man fortsätter driva fram arbetet och informera om dess betydelse för miljön.Passivhus blir mer och mer uppmärksammat. De är något dyrare att bygga, men man tjänar in det i längden. Lönsamheten är dock inte det viktigaste utan känslan av att man gör något bra för miljön..

The tomato is an important crop worldwide, and in recent years it has received great attention due to its rich content of carotenoids, which in studies indicate to have health benefiting properties. Many studies have been done in this area of research and in how to optimize the carotenoid content in tomatoes and tomato products. The objectives of this essay were to summarize present data in this field. The results were as follows:There are nine different carotenoids identified in tomatoes. Lycopene and ?-carotene are the ones that have been given the greatest attention.

Allanblackia is a genus of trees that grows in the rainforests of West, Central and Eastern Africa. Its big fruits contain seeds very rich in oil which has been used by local communities for cooking and making soaps. The native stands are threatened by overexploitation and the demand for the oil is much greater than the supply. Domestication programs, aiming at introducing the trees to small holder agroforestry systems, have been started for some of the species. The main aim of this study was to investigate the soil requirements of Allanblackia stuhlmannii in terms of chemical and physical parameters, as revealed by the soil conditions in native stands. Another aim was to see if these varied along an altitudinal transect.

Syftet med vår litteraturstudie var att beskriva hur personer upplever att leva med dialysbe-handling. Vi vill öka kunskapen om dessa personers upplevelser eftersom de lever med en långvarig behandling till följd av en kronisk sjukdom. Vi använde oss av kvalitativ innehålls-analys med manifest ansats när vi analyserade det material som ingår i vår studie. Totalt granskade vi åtta vetenskapliga artiklar som beskriver känslor hos vuxna personer som ge-nomgår dialysbehandling till följd av kronisk njursjukdom. Analysen resulterade i fyra kate-gorier: Förändrade eller nya relationers betydelse för den sjuke, trötthet och utmattning kan innebära fysiska och psykiska förändringar, sjukdomsinsikt kan bringa hopp inför framtiden och anpassning så att livet kan gå vidare, den krävande behandlingen kan ge en känsla av me-ningslöshet eller bundenhet och beroende.

The Baltic Sea is one of the world?s most polluted seas. Increased discharge of nutrients due to greater populations of people, together with a slow water exchange, creates great stress on the sea. Too much nutrients leads to increased growth of algae and causes problem in the ecosystem. Even if we reduce nutrient discharge the problem still exist in the ocean. When algae dies and sinks, more nutritional substances is produced called "internal eutrophication". This phenomenon will grow in the future due to a warmer climate and the problem is spreading towards the coastal zone, which is an important site for fish recreation. By removing the abundance of algae, the nutritional and toxic substances are reduced and the algae biomass can be a future resource for biofuel production..

Syftet med en integrerad projekteringsprocess är att information tidigt skall tas fram och att projektörer skall kunna arbeta parallellt, exempelvis genom en gemensam BIM-modell. Revit och IDA Indoor climate an energy, även kallat IDA ICE, har i denna rapport visat sig vara två mycket effektiva verktyg som tillåter att information både kan tas fram, i form av energianalyser, men även kommuniceras digitalt med hjälp av så kallade IFC-exporter. Då projektörer får möjlighet att jobba i en gemensam modell kan de arbeta parallellt vilket innebär att information kan tillföras både tidigare och snabbare i projekteringsprocessen. I Revit kan arkitekten enkelt skapa olika utformningsförslag och jämföra dessa med avseende på energianvändning. Analyser från denna studie har visat att energisimuleringar i Revit kan användas för att utforska olika utformningsalternativ och därmed finna optimeringsmöjligheter med avseende på energi och inomhusmiljö.
