In the school subject of the natural sciences it is imperative that the students are given opportunities to ?talk science?, since the dialogues that occur in the classroom have a significant importance for the students? abilities to engage in meaning-making in their learning process. Hence, the student and teacher interaction in the classroom and the feedback given there play a significant role in the students? learning process. The aim of this study is to contribute to the development of formative assessment tools that can mediate the students? meaning-making in natural sciences subjects in upper-secondary school.

Av vår uppdragsgivare SOMAS i Säffle har vi fått uppgiften att konstruera ett bottenlock till kalottventil DN500 PN25. Vårt mål med arbetet är att minimera vikt och bearbetnings kostnad för locket. Materialet består av CF8M enligt Amerikansk standard.[2] Locket ska godkännas enligt SS-EN 13445-3:2002.[1] För FEM-analys används bilaga C design by analysis. [1]Locket ska analyseras i 3 lastfall.  Täthetsprovning av sätet, påverkar locket med en radiallastTryckprovning, påverkar locket med en övertryckslastDrift baklänges, både radiallast och inre övertryck Med utgångspunkt från kalottventil DN500 PN10, som har identisk axel och kalott, analyserades locket till DN500 PN10 i Abaqus med övertrycket 25bar.

Sweden is known to be one of the world?s most equal countries. Nevertheless, out  of  Sweden?s 262 listed companies, only seven  of  them  has  a  female  president, which  is  equal  to  3,4  percent. To  counteract  these  numbers  there  are  several  possibilities.  One  arrangement  that  is  highly  controversial     is  affirmative  actions.  But  there  are  other  options,  for  instance  more  and  more female  networks  are  starting  to  rise  and  many  of  them  also  offers  a  mentoring  program  where  the  mentee  gets  the  opportunity  to  learn  from  someone  with  more  experience.The  purpose  of  this  study  is  to  examine  what  difference  the  female  network  Q80,  with  focus  on  its  mentoring  program,  is  doing  for  the  mentee.  As  an  underlying  purpose  the  study  is  also  examining  what  visions  and  attitudes  the  management  and  the  mentors  is  communicating  within  Q80.  The  focus  is  mainly  on  the  visions  of  Q80,  menas  mentors  and  business  exceeding mentorship.  A  survey  has  been  carried  out  among  mentees  from  three  different  seats of mentoring  programs  where  they  have  answered  19  different  questions  regarding  their  time  as  a  mentee.  Furthermore  interviews  have  taken  place  with the management  of Q80  and  two  mentors.  The  results  are  analyzed  based  on  theories  about  gender,  women  in   management,  leadership,  mentoring  program  and  organizational structure.  The  result  shows  that  Q80i  as  a  source  of  inspiration  and  a  support  for  the  category  of  "career  women"  with  its  core  mission  to  strengthen  the  participation of  individuals  on  a  personal  level  more than  to  work  to  even  out  the  gap  in  the  Swedish  labor market.

AbstractThis paper is about the organisation of the special needs education in three nine-year compulsory schools in Stockholm and the pedagogical thoughts and theories that underlie these organisations. The main purpose of the paper was to investigate whether the special needs education of these schools should be interpreted in accordance with a segregating or an including view on integration as these perspectives are presented by the Norwegian professor Peder Haug. In addition to this I also wanted to investigate if there were any historical arguments in favour of one or another of these perspectives that were still being put forward in today?s debate.The methods that I used were a study of literature regarding special needs education and interviews of a qualitative character with three special educationalists and a special teacher that were working on three different nine-year compulsory schools in Stockholm.The result of the study shows that a big part of the special needs education of the schools that I visited can be interpreted in accordance with the segregating view on integration.The organisation of the special needs education of the three schools differed slightly from school to school but the common trait was that the largest part of this work took place outside of the student?s regular classroom and sometimes outside of the scheduled school day.Two of the schools had special groups where students that were believed to have a need of special education got some, or their entire schooling. That the schools chose to build a big part of their special needs education upon solutions that should be regarded as segregating was motivated on the basis of an effect oriented view on education.

The main purpose of this bachelor thesis is to create a product in the form of a database that can be used for cost estimates of equipment within bio refineries. Through interviews and literature searches the key components and their costs were identified. The database was constructed in Microsoft Excel with different tabs for different categories of components; these tabs are further divided into three parts: one part with costs, one part with calculations and an information part. Most of the part with costs contains the expenses found in scientific papers during the literature study, the calculating part converts different capacities according to user preferences and the currency to euro (?) from 2010 and the information part consists of references and information about what is included in the cost.The database is a good tool for making cost estimates for bio refineries.

This study is based on interviews with five directors of educational administration within the Stockholm County. The purpose is to investigate how the directors of educational administrations, in the different municipalities, describe the relationship between the administration and the local school units. Moreover, the aim is also to describe the administration director?s work in relation to the various levels of the administration. To what extent can it be identified as a dimension of the learning organization described in this report.The study shows that skepticism is usually directed upwards toward the next level in the organization and that the decision-making right for local schools is consistently safeguarded.

This study's primary purpose was monitoring of conservancy operation measures. The fixed sections within ekopark Storklinten owned by the forest company Sveaskog.

The sections were divided into different categories depending on the type of measures they were exposed with. The monitoring showed that the purpose of these measures was fulfilled in general.

This master thesis has been performed at Solvina in Gothenburg for Skellefteå Kraftand Vattenfall Eldistribution. The aim of it is to investigate the consequences of theinstallation of a wind power plant on the mountain Uljabuouda in the vicinity ofArjeplog. Especially the impacts on voltage and transient stability are examined.Furthermore, the amount of extra strain on the voltage regulation equipment and theneeds for increased regulation capabilities are looked into.The wind power plant is planned to be built by Skellefteå Kraft and connected to a130 kV grid owned by Vattenfall Eldistribution. The work comprehends the followingmain parts:- Theoretical studies aimed at wind turbines and power system stability issues.- Modelling of the type of wind turbines assumed to be built on Uljabuouda.- Simulations of different operation cases and analysis of the simulation results.The results from the simulations show that, as far as voltage stability and extraworkload on tap-changers are concerned, the wind power plant does not, in anysignificant manner, worsen the present conditions. The problem of overloading theline between Arvidsjaur and Vargfors is also minor.

In this study we compare Ekot with P3 Nyheter with a comprehension analytical perspective. The more traditional radio news program Ekot differs from the younger P3 Nyheter in a lot of aspects. One of them is that P3 Nyheter?s primary target group is young people between the ages of 20 to 34. Because of this, P3 Nyheter aim to make their news as adjusted to their young audience as possible.

De svenska sjöoperativa helikoptersystemen såg sitt ljus för första gången på 1950-talet. Sedan denna pionjärålder har dessa system varit en del av den svenska marina krigföringen. Men vilken påverkan har de i realiteten haft på denna krigföring och hur har den svenska taktiken påverkats av helikoptersystemen?  Syftet med denna uppsats är att är utröna detta genom att belysa tre årtionden som har varit av stor vikt för det svenska marinflyget: 1960-talet, 1980-talet samt 2000-talet.För att lättare påvisa vilken effekt dessa system har haft på den svenska marina krigföringen så utgår denna uppsats ur den teori som inom krigsvetenskapen kallas för kombinerad bekämpning. Denna teori behandlar de fenomen och fördelar som uppstår då flera vapensystem och/eller vapenslag kombineras för att uppnå en synergieffekt på slagfältet.

To guarantee the customers a job satisfactory executed Sydved has been certified by the ISO 14001 standard. One part of the certification is the standards of soil damages. The soil damages were over represented during 1999 and 2000. It was therefore a need to study the problem in order to see what could be done to reduces these damages. A filed study was carried out on 21 subjectively selected stands from the following five districts: Vänersborg, Falköping, Borås, Jönköping and Åseda. As the study is a descriptive study of the soil damages, their character and extension, only stands were tracks were reported were considered.

Det är av stor vikt att företag är medvetna om vad som skapar värde i deras verksamhet. En viktig faktor är att organisationsstrukturen och dess inneboende informations- och kommunikationskanaler fungerar tillfredsställande. Individers personliga egenskaper kan inverka på vilket förhållningssätt de har till, och hur de hanterar samt kommunicerar information. För att kartlägga individers karaktäristika kan med fördel Myers-Briggs Type Indikator användas, då detta är ett vedertaget, tillförlitligt ändamålsenligt instrument. Genom en fallstudie av tjänsteföretaget Cherry Casino Norr AB:s har en MBTI-kartläggning av åtta distriktchefers personliga karaktäristika genomförts, varefter intervjuer kring deras kommunikationsförhållningssätt utförts och sammanställts.

The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.
