Construction waste from the housing industry includes all unnecessary consumption of building materials. The definition of construction waste is construction materials that has not been built in and becomes waste. Constructions waste can be divided into two types of contributions: operational and work site contribution. Some of the common construction materials in housing industry have such low usage level as 75 % and the rest becomes construction waste. Low usage of construction materials creates unnecessary costs and has a major environmental impact.

Denna studie syftar till att utröna anledningen till att en stor andel av eleverna i gymnasiets kurs matematik A har svårigheter att nå kunskapsmålen, trots att de har minst godkänt från matematik i år nio, samt att finna utgångspunkter för att underlätta övergången från grundskola till gymnasium i ämnet matematik. En enkätundersökning om elevernas syn på matematik och matematikundervisning i år nio jämfört med i gymnasieskolans matematik A har genomförts hos elever i slutet av matematik A-kursen. Resultatet av studien visar att inga betydande skillnader existerar i elevernas upplevelse om stöd/lärarhjälp, undervisningssätt eller bild av kunskapsmålen mellan år nio och gymnasiets A-kurs. Ökningen i tempo och svårighetsgrad upplevs överlag som rimlig. En majoritet av eleverna uppger svårigheter att hantera det ökade kravet på eget ansvar för sin studiesituation som en avgörande anledning till svårigheterna att nå målen.

The main purpose of this Master Thesis has been to investigate issues concerning apple fruit quality in orchards of Äppelriket Österlen. The goal has been to develop a document, for future benefit towards growers and company management in the production of high quality apples.In order to investigate main issues of fruit quality, focus has been on statistics concerning apple varieties, age of the apple trees, new planting, orchard size and growers opinions. Nine growers have been interviewed to investigate opinions and contribution of different growing techniques to increased fruit quality. The investigation showed high age of the trees in production and low rate of planting of new trees. Differences in fruit quality were highest between small orchards. Most growers were satisfied with their fruit quality and with their own measures made to improve it.

This study investigates certified and non-certified teachers in Sweden and how they themselves view the status of their profession. Teacher certifications were introduced to Sweden in 2011, under the assumption that it would raise the status of qualified teachers. Recent results from international studies showed that Swedish students have fallen in rank compared to other countries around the world, and one of the proposed solutions proposed to this was to raise the status of teachers, as well as their pay. A higher status would then solve other issues, such as the low number of applications to university courses related to teaching. This study asked high school teachers, through an online questionnaire, what their views were on the status change the reform was supposed to create.

The choice of harvest date for leys is one of the most important factors affecting the size and quality of the harvest. An early harvest gives a high nutritive value while a late harvest gives larger quantity. Today?s aim to produce high nutritive leys gives early harvest dates both in primary growth and regrowth in northern part of Sweden. The consequence is a growth in the autumn, a "third harvest".The aim of this master thesis was to study the effects of different harvesting systems and their effect on size, feed quality, wintering and economy for conditions in the northern part of Sweden.

The flexibility of the labour market is considered as an instrument for increasing economic growth.Therefore has the use of flexible employment, also called atypical employment, increased. The atypical employment is characterized by insecurity in comparison with a traditional permanent full- time employment. One of the most common atypical employments is the manning employment, which is insecure whether it is permanent or not. The insecurity in the industry is based on insecure income, unpredictable working hours and poor psychosocial work environment.In order to encourage a continued increase of flexibility in the labour market while the need for security for staffing employees would be satisfied was Directive 2008:104 adopted. A certain amount of security has been achieved.

Inbreeding has become a problem in some horse breeds. Studies show that it may lead to inbreeding depression which affects e.g. reproduction traits. In the wild there are mechanisms that make horses avoid mating with close relatives. When selection is done by humans this mechanism is removed and intensive breeding for a few traits, for example good racing results, can become a problem.

This report discusses the development of lessons based on laborations for middle and high school.The purpose of the project was to research the possibility to affect students' attitude towards physicsthrough well-planned stimulating lessons. The lessons were based on the Light and Lasers OutreachKit, a teaching package made by the organisation Laser Classroom, and have been adapted for physicsin middle and high school. The lessons were developed on a pedagogical and didactical ground andwere improved with surveys and peer and self assessment. The lessons were based on laser light and itsproperties. One lesson covered the topic of single-slit diffraction, while the other treated geometricaloptics.

Background: Mass customization has been identified as a competitive business strategy by both companies and academics because of its ability to incorporate the voice of the customer into companies? products and services. Although mass customization may sound appealing, the strategic concept is still developing and firms adopting this business strategy face several challenges. Production concerns are of high relevance since mass customization implies a high level of customer involvement in the product design. Since the areas are closely linked it is reasonable to ask how a mass customization strategy affects production concerns.

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.

Försvarsmaktens slutrapport från perspektivplaneringen 2007 innehåller ett avsnitt vilket avhandlar strategiskt samarbete med andra stater. Flera områden, vilka berör Försvarsmaktens operativa förmåga, identifieras som lämpliga för samarbete med de nordiska länderna. I detta sammanhang uttrycker Försvarsmakten ett bibehållande av nationell strategisk handlingsfrihet trots att uppbyggnaden av den operativa förmågan föreslås delas mellan olika länder. Uppsatsens problem och syfte tar sitt avstamp i ovan beskrivna sammanhang. Detta sker genom att undersöka vad begreppet handlingsfrihet kan sägas betyda när det uttrycks i sammanhang av mellanstatligt samarbete.

Active sensors are used a lot in the society and industry, for example to gain better control over processes or to get proximity sensing features in different products. Within industry there is great interest in developing safe automation products that can be controlled with high accuracy but still at a low cost.The goal of this project is to develop a prototype of a non-contact rangefinder that measures distance using infrared light. The sensor is to be used for various applications in industries with relatively high accuracy and be compact, but at a low cost. By implementing a rangefinder into a product, more accurate detections of an object?s presence can be done.In this project a new distance sensor, EPC600 from ESPROS, was used.

The subject of this study is the ?work strategy? (arbetslinjen); the idea that work and active measures are preferred over cash benefits. The aim of the study is to investigate why the work strategy, which has been almost undisputed for nearly a century, has had widely changing contents over the years, what measures have been taken and which groups have been included. It also attempts to find out whether there is a correlation between unemployment rates, society and the different aspects of the work strategy. The study is conducted as an idea analysis, mainly of dissertations on the work strategy and public inquiries, and covers five time periods from the 1920?s until today.

Det kunskapssamhälle som råder idag medför att organisationer måste rusta sig och hålla ett högt tempo i den förändringsbenägna omvärlden. Kunskap och lärande ses däremellan som nyckelaktiviteter i relation till förändring vilket i sin tur föder innovation. Forskning har påvisat att småföretag förväntas bidra till en större del av näringslivets tillväxt, men att småföretagen samtidigt har behov av att höja sin innovationskapacitet för att möta utmaningen. Studien avsåg därför att utforska småföretag i extern samverkan för att se huruvida ett sådant kunskapsutbyte skapat förutsättningar för innovation hos den egna organisationen. Med hjälp av en kvalitativ forskningsmetodik undersöktes sex småföretagsledare som deltagit i det lärande nätverket, Tillväxtmotorn, via semistrukturerade intervjuer.

The purpose of this project was to find an understanding for why public agents working with introduction of immigrants have decided to co-operate and co-ordinate their efforts. Another purpose was to gain insights in what characterizes this co-operation.Seven interviews were made with practitioners working with these questions on national-, regional- and local levels. The material gathered in this process was then analysed using governance theory and more specific the parts dealing with Joined- up government and Whole- of Government. Two analytic tools were used in the analysis: wicked problems and network.The first of these, wicked problems, was made operational by the use of insecurities. Analysing the interviews along these lines proved very useful in explaining why public agents have decided to try to work together.
