Frånluftsvärmepumpens möjligheter i flerbostadshus

If a building is heated by a heat pump, it is of high importance that the heat pump has a high coefficient of performance. An exhaust air heat pump extracts heat from the building?s exhaust air. The air has a relatively high and constant temperature all year around, leading to a high seasonal coefficient of performance. This thesis examines whether it is profitable to complement an exhaust ventilation system with an exhaust air heat pump in an apartment block that already has geothermal heat pump, district heating, oil- or biofuel heated system.

Effekten av metyljasmonat som skydd mot gnag av snytbagge (Hylobius abietis) på gran- och tallplantor :

The effect of methyl jasmonate on resistance against the large pine weevil (Hylobius abietis) in Scots pine and Norway spruce seedlings. A field experiment was conducted in order to determine the dose-response effects of methyl jasmonate (MJ) on growth and defence to pine weevils in Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) and to compare the effect of MJ between pine and spruce. In addition a complementary greenhouse experiment was conducted with the same aims as above and to determine the amount of resin ducts and their correlation to the feeding of pine weevils. The field experiment was conducted on a fresh clear cutting in Garpenberg, southern Dalarna in central Sweden. The experiment consisted of 30 blocks with three kinds of containerized seedlings: 2-year old spruce, small pine (before shoot elongation) and 1-year old pine (already shoot elongated). They were all exposed to 4 treatments 14 days prior to the experiment: control, 25 mM/L MJ, 50 mM/L MJ and 100 mM/L MJ. Data on weevil damage and seedling growth were collected after the first and the second growing season. The seedlings in the greenhouse experiment were of the same kind and were exposed to the same treatment as the ones in the field experiment.

Timeliness cost for agricultural sprayers : weed control in cereal crops

Evaluation of machinery costs is necessary for selecting appropriate farm machinery. Timeliness cost due to untimely operations is an important component of machinery costs. Timeliness costs can be high for crop sprayers, since pesticide application must be carried out within a short time interval. This Master thesis investigated the timeliness cost and the probability of a suitable workday for spraying. Timeliness factors were estimated for four different crops (oats, spring wheat, winter wheat and barley) using historical weed trial data.

Att finna kärleken @ Internet : en studie om hur kommunikationen mellan åtta par utvecklats från det första mötet online till det första mötet offline

Purpose/aim: The purpose is to get increased knowledge about how the communication had developed from the first contact online to the first meeting in real life and even after when it had turned into a real relationship. I also wanted to know why the eight women I interviewed experienced that the Internet is a good venue to meet and develop a real relationship at and if there existed any differences between those four women who were a bit older and those four women who were young.Material/method: When the purpose with this survey stood clear I decided to use interviews as the method to find out more about my subject. I decided to do eight interviews and I contacted eight women who all found their partners online that were willing to help me and answer my interview questions. I did six of the total eight interviews through MSN Messenger and the other two through the telephone.Main results: I found out that three of the older women had used e-mail and telephone and sometimes SMS communication to find out more about their soon to be partner and after that decided to meet the other person in real life. One of the older women and all four of the younger ones had used a Community and Instant Messenger to communicate with their soon to be partner, they also used the telephone and SMS to communicate with each other but Instant Messenger was the medium that dominated in their wish to communicate.

In search for something "real" - consumers' perceptions of authenticity in regional food brands

Marketing research has acknowledged the concept of authenticity. It is argued that consumers in modern society increasingly search for something real, in contrast to what they perceive as mediated and distorted. Producers of regional food brands has acknowledged this trend, and started to market their products as being authentic. Given the potential practical and theoretical contributions in studying the concept of authenticity in this context, this study aims to explore how consumers perceive these claims of authenticity. Therefore, the purpose of this thesis is to extend knowledge on how consumers come to perceive a regional food brand as authentic.

Konsekvenser av energimodellerad arkitektur

The interest in building low energy houses has increased along with the rising engagement inthe climate questions. With the advancing energy prices it is highly suitably for those whobuild and administer their buildings in long-term to build energy-saving houses. 40 % ofSweden?s total energy consumption constitutes of the energy in residences, therefore it iscrucial to take advantage of all the free energy as we possibly can. With crucial questions likequality of living and profit low energy building is a subject that concerns us all.Three proposals for apartment blocks are presented in this work on a real estate in Stockholm.Each proposal is developed through unique processes of design with the purpose to displaypossibilities to deal with the energy requirements of today and tomorrow through energybased architecture.The first proposal is an apartment block based on a traditional design process, the demands ofthe property owner and it?s affected by opinions from architects.

Linjenätsutredning i Täby kommun.

The public transport network in Täby commune consists currently of two types of bus line of whichboth belong to the category of feeder lines. The first type terminates at Danderyds sjukhus and feedsto the subway whereas the second type terminates at Täby centrum and feeds to Roslagsbanan, asuburban narrow-gauge railway system in northern Stockholm. The trunk bus line that connectsgreater parts of the commune with Danderyd is the ring line 604 and goes both clockwise (604H) andcounterclockwise (604V). The main negative aspect of this structure is the complicity in incorporatingit timetable-wise with other bus lines that share the same route, such as through Enebyberg.The goal of this project is to investigate the possibilities of splitting ring line 604 and connecting theends to two different bus routes that terminate at Täby centrum today. Apart from easing thecoordination with other bus lines through Enebyberg, the extension also creates new directconnections from various areas in Täby to Danderyds sjukhus.

Handledning i informationsfärdigheter för vårdämnen på gymnasiet

The purpose of this paper was to learn more about the strategies used by senior high school librarians and teachers in educating their students' information skills, such as criticism of the information sources. The paper was based upon qualitative interviews with one senior high school librarian and three senior high school teachers. The respondents were asked to spontaneously tell me about their counseling strategies when the students do research assignments in medicine-oriented subjects. The respondents? narratives were analyzed with Carol Collier Kuhlthau?s theories about the information search process and its levels of mediation, as well as with literature about counseling strategies in mind.

Budget i kombination med balanserat styrkort : En fallstudie av kommunal verksamhet

A budget consists of figures showing how much a particular activity has access to during a given year. With a balanced scorecard, these figures and guidelines can be converted in to more easily understandable non-financial instructions for the employees. One of the most significant differences between the budget and the scorecard is that the budget focuses on short-term results while the scorecard focuses on long-term visions and goals. With a long-term thinking the leaders can  set more long-term goals and also make more well-planned investments which increases the possibility for the organization to evolve and become better in the long term. By combining the two instruments a good balance between short and long term perspectives can be achieved, which creates a more effective steeringIn the 1990s, many of the municipalities introduced needs budget, one of them was Gothenburgs municipality.

Effektivare röjningssätt med kedjeröjsågen?

After the mandatory rules for clearing was removed in 1994, the clearing area has increased in Sweden. After the storms Gudrun and Per, the areas became planted with new plants, mainly spruce, but also other tree species. Storm areas are now being invaded by naturally rejuvenated birch in the tilling tracks. Since the birch often is initially growing faster than the spruce it is inhibiting the growth and is also damaging the spruce. The purpose of this thesis is to study the new brush saw with chain and compare it with the conventional clearing saw, mainly in terms of performance and ergonomics. The results show that the new brush saw with chain is very good in almost all clearing operations compared to the conventional clearing saw.
