Better, more efficient fertilizers with great productivity and economic returns are needed, but it is important today to find fertilizers that are also sustainable. It is also important to carefully monitor their impact on the environment, including potential side-effects. In this context, the microbial communities that carry out numerous essential functions contributing to a functional ecosystem are of particular interest. The present study is a complement to a pot experiment that investigated the potential of different waste products for use as fertilizers and how they affect the microbial community. In the pot experiment, the clearest treatment change in microorganism community function was found in the fully fertilized treatment used as a positive control. The question was whether this was indirect, i.e.

EC and WTO have been prosecuting collaboration for some time, which purpose is to liberalize the global market for commerce. There have been some alterations under the last decades. Establishing in other countries than their own is far easier, nevertheless it is getting more difficult.

This master thesis is written in the purpose to discover which attitudes the public libraries in Sweden and Denmark have towards offering popular music to their patrons, how they motivates their choices and why they make the choices they make. The essay focuses on the differences and similarities between the Swedish and Danish libraries and relates their attitudes to the Finnish researcher Sanna Taljas three discourses regarding music policies in libraries.We examined this by sending out a question sheet to public libraries in Sweden and Denmark, the questions were regarding popular music's place in the library and how they build up their music collection. The question sheets were sent out to a total of 116 libraries of which 46 were Danish.The conclusions we drew after our examination were that Danish and Swedish public libraries have a lot in common in the way they regard and distribute popular music in the public libraries. Both of the respondent groups puts user demand high on the priority list as well as having a collection that holds significant works of many genres..

This qualitative study investigates the conditions on the labour market for disabled people by examining which factors and processes contribute to disabled peoples inclusion to, or exclusion from the open labour market. Stigmatisation is also used as an analytical tool to better understand the exclusion of disabled people from the open labour market. The material to this study is drawn from qualitative interviews with the employees of the Swedish Employment Agency which specialises in supporting disabled people to find employment.  In conclusion, disabled people face several barriers which makes them more susceptible to become excluded from the open labour market. Such excluding barriers include a demand for high efficiency and productivity from employers, bigger cooperation?s and public organisations unwillingness to employ disabled people and prejudices from employers, especially against people with psychiatric disabilities. The employees of the Swedish Employment Agency suggest that they would be able to work more efficiently to help disabled people find employment if they had to do less administrative work, and would be able to work with fewer clients per employee.

When facing the fact that high yielding dairy cows has an increasing energy requirements, the practice of adding lipid supplements such as concentrates rich in palm oil and/or palm oil industry by-products become more common. Palm oil containing high levels of C16:0 causes high levels of free fatty acids (FFA) which are linked to larger milk fat globules (MFG) which affect the reaction of lipolysis resulting in rancid flavour and processing problems. Instead of using palm oil, rapeseed oil rich in C18:1 C18:2 can be used. In order to evaluate the effect of added C18:0 and C16:0 on milk lipolysis, 30 Swedish Red lactating dairy cows including 15 multiparous (MP) and 15 primiparous (PP) cows were randomly divided in three groups resulting in 3 10 cow-groups (5 PP and 5 MP cows per group) and fed one out of three concentrate mixtures: control (C), a standard concentrate mixture with no fat added; palmitate (P) as C plus the addition of palmitate methyl ester (10 % in DM basis); and stearate (St) as C plus the addition of stearate methyl ester (10 % in DM basis). Milk yield was registered, and milk samples were collected and analysed for milk composition, FFA content and size of MFG.

Scarcity due to supply, demand or in time is all factors that affect consumers´buying behavior. The scarcity principle describes how scarce resources appear moreattractive to the customer's eyes than unlimited does. When something is scar thecustomer often draws parallels to the quality and price, that the product will bemore expensive and better. People hate to be deprived of choices. When a certainproduct is scar, the customer will desire the product even more.

The purpose of this report is to find a model of statistics for construction and demolition waste, which makes it useful for the local manager at the building site. The intention with the model is that it will be used as a support of the local manager, to direct his project towards reduced strain of the environment. The model will also be used to make it easier to control that the claims from authority and aims for the environment are achieved. To familiarise with the subject waste handling within the building and construction sectorI have done a literature search. I have also been studying rules and regulations regarding the waste handling.

Atlas Copco Tools develops and manufactures handheld industrial tools. Heat and surface treatments are used to provide the tools with certain properties. There are no routines for the choice of treatment or for how to specify treatment on drawings. Production documents that are sent for production abroad may not be clear enough. Some treatments are known as trademarks and there are no instructions for how to specify these on drawings and in CAD-models.The purpose of this master thesis work is to create recommendations for the procedure of choosing heat and surface treatment.

The aim of this study was to develop a load prognosis model for Uppsala district heating system to be used as a tool for heat production optimization. The methodwas to build three models for the different customer types; housing, industry andoffices and then scale them for the total system using data from Uppsala districtheating system. The heat load consists of two parts, one that is temperaturedependent and one that is dependent of the social behavior of the customers. Thetemperature part was modelled with an ARX model using an outdoor temperatureprognosis as input signal. The social behavior part was modelled using the mean ofthe social behavior from some days before and additionally by distinguishing betweenweekdays and weekends.

Vi har genom intervjuer i fokusgrupper undersökt hur gymnasiestuderande 18-åriga ungdomar i Sundsvall reflekterar över bilder och bildpublicering på det sociala mediet Facebook. Tre fokusgrupper bestående av kvinnor, tre fokusgrupper bestående av män har resonerat kring frågor som berör fyra teman: medialisering, integritet, självbild och etik. Totalt ingick 24 ungdomar i undersökningen.Studien besvarar frågor kring varför ungdomar publicerar bilder på Facebook och vilka problem och konsekvenser denna bildpublicering kan resultera i, samt om det finns några skillnader mellan män och kvinnor i deras svar.Studiens ungdomar lever ett medierat liv. De återberättar händelser ur verkliga livet på Facebook med hjälp av bilder. Studiens ungdomar använder sig även av bilder för att skapa sina digitala jag, och ser dessa bilder som en viktig del av hur de uppfattas av andra.

This thesis describes a further development of an existing prototype named Automatic pin bone remover. The further development was requested from the Swedish consulting firm ATM AB. The request of automatic pin bone removers is high and has the potential to be a worldwide leading product.The goal with the thesis work is to further develop an existing prototype. In order to achieve the goal a pre-study of the prototype had to be made in order to define a customer demand specification. The thesis work is then continued by a function analysis which differs from a conservative one.
