Vattendragsrestaurering i teorin och fiskinventering i praktiken : en litteratur respektive metodstudie
Running water-pathways have played an important roll in Sweden and frequently been
manipulated. One profound change was made during the period of logging when
streams were cleared from obstacles as big boulders, sharp bends and side-streams.
Dams and different constructions gave control of the stream water and the streams
became channel-like with a homogen structure. This interference gave problems for
many fish populations and resulted in a shortage of feeding habitat, over-wintering
habitat, spawning habitat, unnatural flow regimes, sedimentation, unnatural
temperature fluctuations. Many of these historical changes of the watersheds are now
subjects for restoration, ie., bring back the streams to what we believed it was before the change. However, what once existed in terms of complexity is now gone and difficult toreplace.
Utveckling av HPLC-metoder för kvantifiering av nyckelkomponenter i en villkorad emulsion
Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.
Design och tillverkning av en stereoanläggning med aktivt delningsfilter
This thesis is the result of the author?s interest in music and electronics, namely the design and manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart. The active design naturally results in a more complex system comprised of a multiple number of components. This report deals with the theoretical aspects of preamplifiers, crossovers and power amplifiers as well as power supply and control.
Röstförmedlingen : Att skapa en kreativ designlösning till ett nytt företag
It becomes increasingly more important that, as a new buisness, both to be seen and heard in an increasingly harder competition situation where the range of similar products and services increase. It requires a well planned and well thought visual profile to succesfully stand out on the market. To give a good impression, this profile should be both distinct and aesthetically appealing. In the making of a new profile it requires creativity to succesfully think in new directions and to separate from the competition.This practical report presents the production process for a designsolution to the new website Röstförmedlingen (Voice agency), a commission from the production and commercial bureau Bartos media. The task in this project was to create a graphic profile and a lofi-prototype that would represent Röstförmedlingen as a buissness.
Energikonsumtion hos en diskmaskin
The dishwasher is a wide spread product that occurs in many households. It saves the user time,water and energy. When using a dishwasher instead of doing dishes by hand a lot of energy issaved.The importance of lowering the energy consumption does not only come from the consumerwinnings but also from an environmental point of view. Scientists are certain that the globalwarming comes from the emission of green house gasses that is created by human consumptionof oil, gas and coal.Dishwashers today are a lot more energy efficient than older dishwashers, but there are stillmargins to lower the energy consumption. The aim with this project is to investigate thedishwasher and it?s washing cycle, noting different phases and components that contribute towaste of energy.
Horisontell skjuvkapacitet mellan plattbärlag och pågjutning i pelardäck. FE-simuleringar i 3-D och jämförelse mellan beräkningsmetoder
This report describes how the process has evolved during the creation of a new web page forthe company Scandinavian Travel Agent DMC. The design methods that have been used aredescribed and also how parts of the webpage have been created by using the design methodresults. Our reflections around design and functionality are explained and how usability hasbeen our main focus during the master thesis. We also describe how it has been to work withan external costumer and how the tasks constantly have changed and been added as theprocess has continued.The background to this work is that AB Scandinavian Travel Agent DMC need to improve theircurrent web page. This to give the clients better needed information about destinations, butalso to stand out in the competitive travel business.
Digital Storytelling
The purpose of this paper is to analyze and map out the cyber culture of the Internet and its all users, identity, design theories and services. How people communicate and how they build up their identities are some of the baselines. I will also discuss the important aspects of Interaction design and how this can be used in a Community for digital storytelling.
The Internet, or new media, was founded in the 60?s by some great philosophers (McLuhan, Rheingold, Lambert and more). With influence from their books I will discuss and analyze what kind of media the Internet is and how it can be seen as extensions to our senses, as McLuhan claims.
Energikartläggning vid biogasanläggningen, Kungsängens gård
The purpose of this thesis was to make an energy survey and quantify energy flows of
individual unit operations associated with the biogas production in Uppsala Vatten och Avfall
AB:s biogas plant, located at Kungsängens gård. Moreover, large consumers of energy would
be identified and analyzed. The objective of this energy survey was to obtain a detailed
understanding of the energy use in the biogas production.
The energy survey was divided into two parts: electricity and heat. Each part was treated
separately and with somewhat different approach. To estimate the electricity usage during the
projcet the rated power of each selected unit operation was noted and multplied with the
measured time of usage.

Mänsklig påverkan på mindre vattendrag i skogslandskapet : en inventering av vägtrummor och skyddszoner kring dessa i Uppsala län och norra Västmanlands län
Interference in an ecosystem means a disturbance. When harvesting, forest roads have to be
build to cope with heavy duty vehicles. Crossing brooks can not always be avoided. In this
case bridges or culverts have to be built. There are many different kinds of culverts and
depending on what type you choose and how you place the culvert, the watercourse and the
water organisms can be harmed in different ways.
Tradarparet
Transportbranschen kan beskrivas som samhällets blodomlopp och vi är alla beroende av dess tjänster i vårt dagliga liv. Men denna bransch står inför stora utmaningar. Konkurrensen har drivits så långt att vissa aktörer bryter mot lagar och utnyttjar lågavlönad personal. Vilka är konsekvenserna av denna situation? Och vad kan man göra för att vända på denna trend? Sebastian Brännvall har utforskat hur man kan förpacka information så att denna sticker ut och väcker intresse hos en bredare massa.

Samhällskunskap och digitalteknik : Om undervisning i tre gymnasieklasser och dessanvändning av digital teknik
Syftet med uppsatsen är att bidra till ökad förståelse om samhällskunskapsundervisningens innehåll, genomförande och utformning på gymnasiet där digital teknik används.Fokus i uppsatsen har legat på att genom observationer och intervjuer i tre klasser och med de två lärare som undervisar klasserna få inblickar i hur lärare designar undervisning och hur elevrollen kan förstås när digital teknik används i ämnet samhällskunskap. Till hjälp för att analysera resultatet har analysmodellen Learning Design Sequence och i synnerhet begreppen lärsekvenser och iscensättning använts. Det senare begreppet syftar på faktorer såsom lärarnas arbetssätt och tillgängliga resurser som präglar en lärsekvens, vilket kan vara elevernas arbete med en uppgift för att nämna ett exempel.Resultatet visar att datorer och Internet ofta i någon form ingår i lärarnas design av undervisningen. Exempelvis har lärarna genomfört genomgångar med hjälp av Powerpointpresentationer samt utformat uppgifter där elever ska använda sig av sina datorer. I elevrollen ingår bland annat att vara dator- och Internetanvändare men också av att anteckna och lyssna.
Design och oro : En studie om inredning och möbeldesign och dess möjligheter att minska oro hos dementa
Between 1999 and 2009, I followed three of my grandparents, all of whom suffered from dementia. Numerous times, when I visited them in their nursing homes, I was met by residents of the ward who were very unhappy. Through conversations at home with my family, I understood more and more that this was a commonly occurring problem at nursing homes. All too often it was solved with heavy medication, which made the residents tired and they slept more often.During my undergraduate education at Konstfack, I have reflected on whether I, as an interior designer and furniture designer, can have an influence on spaces and furniture so that dementia patients can experience greater calm and security. The idea is if that I perceive the environment as calm and secure, I will also be calm and secure.In my degree project, I want to study how interior design and furniture design can contribute to decreased agitation in people with dementia in nursing homes..
