The focus of this study was to examine the nutrients and benthic organisms of the bay ?Mönsteråsviken?, which is influenced by eutrophication. The purpose was also to look at an interesting gradient forming in the bay, namely the distance from the river outflow of Lillån. At 18 sampling sites in the bay samples of water, sediments and benthic organisms were collected in late April of 2011. The water was analyzed for nitrate, phosphate and chlorophyll.

Freshwater ecosystems have long been neglected as an important part of the global carbon cycle. However, research shows that most of the world?s lakes are net-heterotrophic and consequently emitters of greenhouse gases to the atmosphere. In many boreal and north-temperate lakes, most of the yearly emissions usually occur in spring, shortly after ice-thaw. The aim of this study was to quantify the flux of carbon dioxide (CO2) and methane (CH4) in three boreal lakes, during this annual event.

This thesis work researches what motivates swedish Facebook users to pass along and shareinformation on Facebook, their attitude towards shared information and what affects this behavior. The goal of this thesis is to research todays behavior and motivations to enlighten  what makes information worth sharing to others on Facebook, instead of simply attracting attention. By using a web survey we have collected data by sampling a part of the actual population  of  swedens Facebook users.Our results show that swedish Facebook users main reason for using Facebook is to socialize with offline friends and share information to show otherssomethingtheybelivetheywillhaveuseforand/orwillappriciate.WecompareourfindingstoexistingresearchandtheFIROtheoryabouthumaninterpersonalneeds.Wefindthatuserssharinghabitscanbeidentifiedasmotivatedbyinterpersonalneedstomaintainsocialbonds,influenceothersopinionaboutthemselves,feeluniqueandstandoutinthecrowd.WeconcludethathumanneedsarecontributingtosharingactivityonFacebookandinfluencethesharinghabitsoftheSwedishFacebookusers.Theusersshowacriticalviewonsharingbehavioringeneralbutdonotbelievethattheyshareforthesamereasonthemselves..

During test flights SAAB uses the data acquisition system COMET 16. The part of the system that receives the signals from the sensors and converts them is called KSM 15. The purpose of this thesis is to develop a data acquisition module on stacked PC/104 modules with a lower production cost. Our work has been divided into one part about analog signal conditioning and a second part with digital filtering and memory management of the sampled data. The analog part, designed of regular components like instrument amplifiers, voltage references, operational amplifiers and multiplexers, adjusts the sensors signal levels for the ADC?s that converts the signals.

The thesis demonstrates a low-cost, low-bandwidth and low-resolution Analog-to- Digital Converter(ADC) in 0.35 um CMOS Process. A second-order Sigma-Delta modulator is used as the basis of the A/D Converter. A Semi-Uniform quantizer is used with the modulator to take advantage of input distributions that are dominated by smaller-amplitude signals e.g. Audio, Voice and Image-sensor signals. A Single-bit feedback topology is used with a multi-bit quantizer in the modulator.

This degree project studied surface waters on Kåbo Golf Course in Uppsala, Sweden, with the aim of determining the status of the water and how it is affected by the activities of the golf club, and to obtain suggestions of measures to create better conditions for the water environment on and around the golf course. The project forms part of the environmental protection work of Kåbo Golf Club, which is working towards achieving environmental certification from the Swedish Golf Association (SGF). The study is based on literature studies and quantitative and qualitative field studies of water on the golf course, with the focus on environmental factors identified as being important for the golf industry and on strategic environmental goals developed by SGF. The number of open water bodies in the Swedish landscape has substantially declined during the past 200 years, so it is important to save those that remain. This study showed that the surface water at Kåbo Golf Course is an important element in the surroundings since the area contains few wetlands, which can be a habitat for large numbers of species. The stream and ponds on Kåbo Golf Course also have the important function of serving as water hazards in the game and adding difficulty and variety to the course. Since Kåbo Golf Club wants its surface waters to look aesthetically appealing, extensive algal growth and drying up of ponds during parts of the year are regarded as problems.

Att den illegala fildelningen är ett problem för den svenska filmmarknaden som måste bekämpas är något som Antipiratbyrån vill framhålla. Piratbyrån å andra sidan menar att problemet inte är så stort och inte ens värt att lägga energi på. Vi ville därför undersöka hur den illegala fildelningen verkligen påverkar den svenska filmmarknaden. Detta gjordes genom att först intervjua både Antipiratbyrån och Piratbyrån för att få fram olika synsätt på problemområdet. Vi gjorde även en litteraturgenomgång där vi fann relevanta teorier som vi utformade vissa antaganden utifrån.

Abstract The benthic macroinvertebrate fauna of 22 natural springs on Öland was sampled, by using a time-standarized kick/sweep sampling technique, in the end of September and early October. The aim was to determine the number of species and their abundances in the macroinvertebrate communities in springs and how/why these may change between different springs. Likewise there was a purpose to investigate possible differences between springs considering the proportions of the number of species and the abundances of the five functional feeding groups; shredders, collectors, filter-feeders, scrapers and predators. There was also an aim to investigate if the distances betweeen springs had any influence on similarity between the communities of benthic macroinvertebrates of the springs. Analysis from the springs collected material showed several interesting patterns in the number of species and their abundances when compared between springs devided into groups depending on their environmental factors such as depth and pH.

För att äldre personer ska kunna utföra meningsfulla aktiviteter och känna gemenskap med andra krävs att de kan transportera sig. Det är viktigt för att bibehålla god hälsa och uppleva livskvalitet. Många äldre har svårighet att transportera sig med vanliga bussar på grund av funktionsnedsättningar som kommer med stigande ålder. Syftet med denna studie var att beskriva vad En buss för alla har för betydelse för äldres delaktighet i samhället. Studiens design var kvalitativ, en målinriktad sampling gjordes och undersökningsgruppen valdes ut från förutbestämda kriterier.

This master thesis takes its point of departure in the conflicting worldviews of modernism and post-modernism. As traditional segmentation theory springs from the modernist worldview, this study aims to contribute to the understanding of the complexity regarding market segmentation for lifestyle brands in contemporary society, where the consumer is often claimed to be post-modern. The research was conducted in Malmö and Lund and involved 25 Converse users as respondents. The methods used in this thesis starts with observations as a sampling technique in order to locate the respondents. Short interviews and photo documentation followed.
