During the autumn 2009, a 15 hp degree project was accomplished. The objective of the study was to describe different equipment alternatives, suitable for fresh market apple harvest. A field study was conducted during the harvest period to evaluate the efficiency (kg / person/ hour), using the different equipment. Four different systems are described in the study; Pick-ing-bag, Picking-train, Pluk-O-Trak and the Conveyor Harvester. The information about the systems is based on interviews with growers together with previous studies.

Construction of wetlands in the agricultural landscape may reduce nitrogen and phosphorus transfer to streams, thereby reducing the eutrophication of lakes and seas. The agriculturalstream Lillån, a tributary to stream Sagån, ends up in Lake Mälaren and is transporting large amounts of these plant nutrients. The aim of this study was to estimate how hypothetical wetlands of different size and location may reduce nitrogen and phosphorus load from stream Lillån. Estimated nutrient retention in several small wetlands was compared to retention in a single large wetland based on existing data from the agricultural stream and from a nearby smaller stream. Retention in the stream was suggested to decrease along with the nutrient concentration in the water.

This study investigated the possibility of implementing three standards, Transistion Minimized Differential Signaling (TMDS) and two versions of Stub Series Terminated Logic (SSTL), for inter-chip communication in a specific manufacturing process. The two SSTL standards were implemented in one transceiver system while TMDS was implemented in a separate system. The evaluation was done with Spice simulations on schematic level with some parasitic capacitance and resistance. The idea was to investigate the possibility of implementing these standards and get an idea of eventual shortcomings. In order to create models as a basis for evaluation, simulation environments with models for circuit board and packages were created and transmitters and receivers were designed.

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

This thesis has been done on a haulage contractor company named GP-Last (AB Gustav Perssons Åkeri) and the purpose with the paper was to analyse their traffic from Malmö to Stockholm and leave suggestions on efforts that GP-Last can use to increase their level of transportation quality. This has been done with two main questions, which problem do they have today and which efforts they need to do to solve their problems? Through a case study with interviews as method to collect data it showed that GP-Last had four main problems.        Not enough information about their freights. The transport planning unit in Malmö doesn?t have the exact delivery address when GP-Last begins to bring in the gods.        There are no clear routes.

Marketing is a broad subject with many different areas. Part of the marketing that has been of great importance is the 4P:s also known as the marketing mix. Marketing mix is included in one of the traditional marketing approaches. In recent years there have been some changes and have begun looking at new ways of looking at marketing. One of the ways is entrepreneurial marketing to the effect that the company tries to use its resources optimally.

The aim of this essay is to create an understanding, of how teachers comprehend knowledge, grades and tests in a school context. It is important to get a grip of the different parts of the teacher?s reality. The test, the grades and knowledge are deeply connected as a part of a whole. The teachers view on knowledge can not be understood without asking about the practical parts of their work and understand how the different parts are dependent on each other.The main material consists of interviews with four teachers that work in a public mandatory school in the south suburbs of Stockholm.

The overall aim is to examine how the European Union Water Framework Directive has affected the local water management in the catchment Märstaån situated in the eastern part of the lake Mälaren river basin, Sweden. The first part of the study gives an historical overview of the area with focus on how the old agricultural landscape was handling the nutrient load from farming activities by means of different kinds of wetlands. By using the concept of the procedural landscape, introduced by Torsten Hägerstrand , together with historical maps with dates starting from the 17th century, the pre-modern landscape is analyzed.  The second part is an investigation, based on qualitative data, on how the different actors in the catchment area work together to secure the water quality for the Märstaån river. The analysis shows that the Märstaån catchment river systems are mostly unchanged in the rural areas.  The exception is the mainstream section of the Märstaån river running partly underground today and the Halmsjöbäcken river that is heavily affected by the Arlanda airport situated within the catchment area.

The purpose of this essay is to analyse the descriptions of young girls' experiences of internet contacts, which have led up to sexual abuse. The aim is to give additional understanding and knowledge concerning grooming.       Grooming means that somebody gets in contact with someone else with the intention of committing sexual violations at a later stage. In most cases this concerns adults who contact children. We have chosen to confine ourselves to focusing on the grooming on internet that has happened to girls. By means of thematic analyses of texts from the books Jag kände mig speciell, grooming på internet, 2012 and Alexandramannen, vår tids största nätsexhärva, 2009, we have found certain themes and linked them up with previous research-work and also theory of social psychology.

The aim of this paper is to study how multiculturalism is expressed in the Swedish labour market policy. The method used for the investigation is a discourse analysis which study social and political processes in the society as created through language. The perspective of the discourse analysis is a social construction that considers that language is a social production created in a discursive way. It produces and reflects social process in the language.By using theories of national identity and multiculturalism we aim to investigate how multiculturalism is expressed in the labour market policy. With this method we aim to analyze the discourse of a political report made 2008 by the current government about integration strategies in Sweden.

 Why is it that we still live in a society where an individual's social background plays such a big part in their chances of reaching a higher education? Despite the numerous educational policy reforms, especially in Sweden, it still seems that an individual's career choices are pretty much related to what kind of social class they grew up in. Sociologist Pierre Bourdieu claimed that social class is reproduced in the school system, and that students from the lower classes are much less likely to reach a further education than students from the middle or upper classes due to injustice in the school system. One thing that plays a big part in this "Catch-22" situation is the concept that Bourdieu calls habitus. Habitus could be explained as an individual's taste, knowledge, ability to master the spoken language, etc. Your habitus is manifested in the choices you make, the music you listen to, how you dress and the way you speak, and it determines your relation to the education system and life in general. As part of my essay, I wanted to interview students from lower or working class at my school, Konstfack, to see if they have had any negative or positive experiences from their encounter with a higher education. And if so, could they be linked directly to their social background? As a reaction to my own and my interviewees? experiences and frustration, I use the concept of habitus in my practical work.

The purpose of our paper was to understand the motivators that kept the social workers within the profession. Social workers' have a profession that, to the greatest extent, means high working load and difficult problematic issues. On the basis of this starting point we asked us why so many social workers still choose to remain within the profession for several years. The purpose of our paper is to understand what motivates the social workers to stay within their profession. To understand which are the motivators, we decided to use the theory salutogeent perspective with Aaron Antonvsky's sense of coherence.
