Urbanization has for a long time been a threat to our biodiversity. Epiphytic organisms such as lichens have been negative affected by traffic pollution and the new urban environment surrounding their old habitat (van Her 2001). Another epiphytic organism is the green algae Desmococcus olivaceus. Unlike lichens the green algae is favoured by polluted areas. The aim of this study was to investigate if time in urban environments affected the cover of the green algae on old oaks.

To work with environments outdoors for people, animals and plants is the main topic for the landscapearchitect. On several occasions the work is about public places that is to be in relation with other parts of the town. It is about the activities and the life that take place. The physical environment and the interpretation of it gives possibilities or obstructions for people who moves around or spend time in it.Since public places, parks and places for movement are used in daily life they strongly effect the people who use the places. The concequences of this effect can be positive or negative experiences.A positive example is a passage over a brook on the way to school while a negative one is to be afraid while passing a tunnel when it is dark outside. Other examples of concequences are stress effect from traffic noice or calming environments with twitter of birds. The physical environment is also a part of the total interpretation of a town.

The aim of this study is to highlight the computer as a learning resource in the education and give us knowledge about how the students uses the computer in year one in a selected High School where one computer per student were introduced in autumn 2011. The aim is also to contribute to the discussion about how the computer can become a natural learning resource for all students in all subjects, including the students in need of special support.How are the High School students using the computer?Are there differences in computer use, whether the student is in academic or vocational program?Are there differences in computer use between boys and girls?Do the student experience that the digital competence is increasing together with if they experience the computer as aid?In what degree do the teachers encourage the students to use the computer?How much do the students use the computer to learn mathematic?The study is based on a survey of all students in year one in a municipal High School.The result of the study is showing that the students first of all use the computer to play music, surf the Internet and to be logged in on social media (eg. Facebook). The students have learned to use the computer for the tasks they need, although the teachers don?t encourage the students to use the computer in any higher means, not in mathematics and not in other subjects.

This study examines the use of building modeling and energy simulations in the design process  of  a  building.  The  take-off  point  is  the  notion  of  energy  simulations  being needed early and throughout the building design process, and that the lack of energy simulations may be explained by the fact that they are time consuming and therefore often too expensive. A greater interoperability between software tools used by relevant disciplines,  such  as  the  architect  and  the  energy  specialist,  would  create  smoother workflows, which would reduce this cost and open up for more frequent and iterative energy  simulation  processes.  The  study  is  an  assessment  of  the  modeling  tool  Revit and  the  simulation  tool  Virtual  Environment  and  whether  they  can  create  smoother workflows, and make leeway for a more frequent use of energy simulations throughout the  design  process.  It  also  investigates  the  limitations  of  what  can  be  examined  by simulations in Virtual Environment. This will hopefully help clarify the future role of energy  simulations  in  design  processes.  The  method  is  a  trial  by  error  approach  of testing the two software tools by building and simulating a model. The results of these tests  show  that  the  workflow  is  not  optimal  (and  therefore  time  consuming)  for frequent  and  iterative simulations  throughout the  design  process,  but  it  also  reveals some  great  possibilities  of  what  can  be  performed  with  these  two  powerful  tools  at hand.  Further  development  with  regards  on  platform  independency  of  the  building information  model,  including  seamless  exporting  and  importing,  seems  necessary  to strengthen the future role of energy simulations..

Syftet med detta arbete är att undersöka hur förändring av material påverkar varseblivningen av objekt när formen lämnas oförändrad. Detta kan vara av intresse då spel med realistisk grafisk stil blir mer och mer högupplöst vilket samtidigt ställer högre krav på de grafiska utvecklarna att framställa verklighetstrogna material.Jag har utfört en kvalitativ undersökning med personintervjuer av sex personer. Dessa sex personer har fått se tre objekt där de fått definiera objektets syfte. Intervjupersonerna fick sedan se objekten med olika material där mina frågor haft som mål att få respondenten att motivera uppfattat material samt det uppfattade materialets egenskaper. De intervjuades motiveringar om objekt och material har jag sedan tolkat utifrån litteratur om psykologi, främst om kategorisering som George Lakoffs bok "Women, Fire, and Dangerous Things" (1990) beskriver.Min undersökning har visat att uppfattningen av textur kan förändra ett objekts syfte och funktion.

Superficial digital flexor tendon injuries are common causes of premature retirement or pre-longed convalescence periods for race horses. The curve gradient at Täby Galopp race track is very small and most races as well as high speed training are done on the left rein. It is believed that the horses left foreleg is under considerably more strain then the right foreleg when being ridden on the left rein during gallop at high speed. During gallop on the left rein the horse puts its entire weight on the left foreleg when regaining ground contact. The purpose of this study has been to find out, through analyzing the statistics concerning the horses that visited the ATG clinic at Täby during a period between January 2003 and September 2006, whether there is a higher frequency of superficial digital flexor tendon injuries on the left leg rather than the right and if so, can this support the theory that the design of the race track in combination with continuous left rein races can be a contributing cause of these injuries. The result of the study shows that 57% of the tendon injuries occurred on the left front leg and 38% on the right front leg. The difference is not large enough to support the above theory of the underlying cause of these injuries..

The study shows the current need for security solutions concerning work with information in different areas.Investigations will show important solutions for printers? needs to meet the increasingly harder demands forfast and safe digital communications. Important factors to be analyzed in the investigations are: access todifferent types of information, workers authority of information, access to the data base register internallyand externally, production solutions for an effective fault detection and data base solutions fororders and distribution.Planned and unplanned stops result in a standard of value in interruptions. Internal data bases areprotected by so-called ?Fire Walls?, ?Watch Dogs? and Virtual Private Networks.

To be able to evaluate different radio waveforms in a laboratory environment FOI in Linköping has developed an experimental system for radio communication called Rasmus. The system consists of a transmitter, a channel emulator and a receiver. The transmitter modulates a digital signal to a desired analogue waveform. The channel emulator is used to simulate a real radio channel. The channel emulator distorts the signal by splitting it up in several propagation paths.

The last few years a lot of media air time has been devoted to training, sports, health and weightloss on a more personal level then before. The new media arena is beeing used at its´ maximumto broadcast wievs on how we should eat, look, exercise and live. This thesis is trying to makebetter understanding on what people in general think is important when it comes to physicaltraining and motivation with the aid of digital media and IT systems. The thesis describes aworkshop that was conducted within the frames of Participatory Design and the outcome of thatworkshop. The workshop was conducted with a group of lead users (in this case instructors at avery large fitness center in Umeå, Sweden) and the main question was ?How can IT be used toachive a positive effect on physical exercise if motivation is the focus??.

Bakgrund: De senaste åren har alltmer musik börjat distribueras digitalt via Internet. Detta har framförallt skett via fildelningsnätverk men under de senaste två åren har allt fler legala tjänster växt fram. Prisnivån hos dessa tjänster är väldigt enhetlig och återförsäljarna har små marginaler på sin försäljning. Teorier påstår att Internet ger möjligheten att skära bort delar i distributionskedjan och det kan leda till lägre priser. Internet ger också ökade möjligheter att ändra priser på daglig basis.

In this study I examine the debates, intentions and ideas concerning the physical and created schoolroom as they appeared in the journal Lärarnas Tidning - Svensk Skoltidning (Teachers Journal ? Swedish School journal) during the period 1962-1974. The built and created school building and its environment has been a relatively neglected topic in Swedish pedagogical research.When the Swedish comprehensive system transformed during the sixties, with new curricula and a common nine year school, many school professionals realised the need for a new and pedagogically adjusted schoolhouse.The early seventies marked a decline after a ten year period with an extensive building program affecting large parts of Sweden, and where schoolhouses had been an important part. The debate concerning the new Swedish school building was sometimes inspired and refreshing, but resistance and bitterness was also expressed. In part, this should be seen against the backdrop of the introduction of a new educational system, using new and sometimes untested pedagogical ideas, together with the fast transformation of the Swedish society.The research method is an exploratory textual analysis focused on five different issues: ideas concerning community centres and integration, participatory and democratic issues about the built environment, the school building as a pedagogical tool, aesthetic considerations, and the working environment.

In my study I have chosen to examine the mathematics in children's free play and everyday situations, with focus on sorting and classification. The purpose of the study was to see how children express their mathematical knowledge. I have chosen to use a qualitative method in my examination, here I did observations in a children's group where the children were between three and six years old. I also did interviews with the teacher's on the department to see how they relate to the mathematics and how they formulate the department to achieve as good a learning environment as possible.The result shows that the teacher's approach is incredible important to the children's learning ability and that they are always present to challenge and discuss together with the children. The observation indicates that children use mathematics all the time in their everyday situations and that it is the interaction between individuals and environment that affects children's development. .

The purpose of this study is to generate knowledge about how teachers relate to students with language impairment in learning situations, with particular focus on working memory. The questions are: What kind of knowledge do teachers have regarding language impairment and working memory?, What experience do teachers have regarding lack of working memory abilities among students with language impairment and which consequences do the teachers believe such defects may have for the students? and How can teachers create a learning environment that reduces the working memory demand for students with language impairment? A review of the field shows that there are gaps to fill regarding students with language impairment and working memory. Language impairment has so far been neglected by researchers and within the public debate. How working memory capacity affects the students has only recently begun to receive attention in school and research.

De senaste decennierna har en rad streckkodstekniker utvecklats för att grafiskt representera digital information. Gemensamt för dessa är en strävan efter hög densitet, det vill säga kapacitet att lagra mycket data på en liten yta. Densiteten begränsas emellertid av kravet på precision vid tolkning av den digitala datan, eftersom felaktigheter i digital data kan resultera i omfattande informationsförlust.Analog information, exempelvis ljud, är däremot inte beroende av exakthet hos underliggande data i samma utsträckning. En analog ljudsignal kan beskrivas och återges approximativt, och ändå tolkas korrekt av en lyssnare. Detta faktum gör att det finns fördelar med att representera ett ljud utifrån dess analoga egenskaper.

This report is about accessibility in a station environment. Studies have been made about how an accessible building should be designed. Accessibility is an important issue when striving for a society with equality as the foundation. Sweden is one of the most accessible countries when speaking about the built environment. A result of prosperity and a well-managed democracy.
