Undervegetation : användning av vedartade marktäckare i anläggning

The use of the robust and durable woody ground covers is increasing, not in the least in public places. The group includes low shrubs of different height that effectively build low, tight vegetation that covers the ground. Despite all the good qualities the knowledge about them is quite low and there are ideas about them of being dull. The woody ground covers manage to struggle against weeds effectively by competing for nourishment and water, but above all, by the canopy of the ground covers that prevent the weeds from getting enough light. In that way the woody groundcovers can effectively compete with the annual weeds.

Ljudlandskap i kulturmiljöer

This bachelor thesis aims to draw attention to sound in the heritage sector in Sweden. In particular, to thesoundscapes that can be identified in our cultural heritage environments. Sounds in an environment, here calledsoundscapes, affect our perception of the environment and how we remember it.To find out how the heritage sector uses and would be able to use sounds, I have firstly studied if audio recording iscomparable with the visual photographic image. I then present examples of sound documentation concerning theconservation of built environment. In addition, I have interviewed five key informants who all have a centralresponsibility for five cultural heritage environments.

Olika fönster mot samma omvärld ? En undersökning av omvärldsbevakningen på Stockholms stadsbibliotek och Akademibokhandeln i Stockholm

The aim of this thesis is to explore how a bookstore chain and a public library meet the needs of their customers through environmental scanning. The empirical material is derived from six semi-structured interviews with six informants, three from each organization, together with an analysis of internal documents. The method used is a case study and the theoretical framework is based on models used in the process of environmental scanning, as described by Choo, Hamrefors and Hedin & Sandström among others, and which facilitate a comparison of the environmental scanning of the two organizations. The results of the study indicate that the library, as a public organization with a mission in society, perceives the environment as society as a whole and all its members as their users, whereas the bookstore concentrates on the sectors of the environment that affect their sales. The consequences of these different views are that the library is more active in the environment and uses surveys as a basic source of information, while the bookstore is more passive, and relies on statistics for information.

Vi hör inte läraren! ? En enkätundersökning i årskurs sex om upplevd ljudmiljö i skolan

Noise in schools can have negative effect on the teaching environment and speech perception. The national Child Environmental Health Surveys (BMHE) conducted in 2003 and 2011 studied how 12-year olds experience their sound environment in school. Results showed that the number of pupils that experience annoyance from noise increased from 2003 to 2011.Aim: The aim of this study was to study how 12-year olds perceive their sound environment in school.Methodology and material: A quantitative questionnaire survey was conducted in the sixth grade at two schools. The questionnaire used included questions from BMHE and self-produced questions. Sixtynine students answered the questionnaire.Results: Over 50 % of the respondents experience annoyance from noise in school several times a week.

Kylvattenkemikalier i länsvattnet ifrån världshandelsflottan : En approximativ beräkningsmodell för årliga utsläpp av kylvattenkemikalier ifrån världshandelsflottan

Fartyg använder sig av stora dieselmotorer för framdrift och för att producera elektricitet ombord. Motorerna samt diverse kringsystem har behov av kylning och till detta används kemikaliebehandlat vatten i ett slutet kylsystem. Vid tömning och läckage från systemet tenderar det kemikaliebehandlade vattnet att hamna med länsvattnet. Länsvattnet genomgår en reningsprocess innan det pumpas överbord. Denna reningsprocess är inte utformad för att avskilja kemikalier och dessa tenderar att hamna i havet.

Ett kvalitativt arbete på väg : - En kvalitativ undersökning för att öka kunskapen gällande systematiskt arbetsmiljöarbete inom en organisation som arbetar med vägservice.

The purose of the study is to increase knowledge regarding systematic enviromentarl work in an organization that works with road services. Work on the road is done in a hazardous environment with constant danger regarding the life of the individual. The site of the work varies in accordance with where the needs ae . This requires skilled workers capable of working independently and that they are experienced din doing their own risk assessments in accordance with the individual believes that the situation calls for work to be performed safely. The study was conducted with a qualitative research approach in which four employees of different positions, knowledge, experience and vision to work in a hazardous environment were interviewed. The focus rests on the organization, management, and individual aspirations for a safe and secure working environment. The study adds weight to the relationship between the purchaser of the work and the organization as a prime contractor due to the compexity of the organization.

Monitoring and pest control of Fruit flies in Thailand : new knowledge for integrated pest management

Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.

Low Temperature Waste Heat Solutions : with proposals for energy technological actions based on Scania?s building 64

The report comprises two separate parts:part 1:  Temperature needs for district heating in the paint shop for axles in building 210part 2:  Energy and low temperature waste heat solutions in heating and cooling systems for   building 64 with surroundingsThe paint shop for axles in part 1 has air quality requirements in places for coating of axles. Toachieve desired air properties there are different process ventilation systems, which consist ofventilation coils for heating and cooling, plus air humidifier. The ventilations coils for heating usedistrict heating. Today the ventilation coils use water of 100°C to achieve necessary air demands inthe coating boxes. This part of the report investigates whether the existing system would achievethe air requirements with a water temperature of 75°C instead of 100°C in the ventilation coilsduring the coldest parts of the year.

Metodutveckling för planering och genomförande av dikesrensning med moderna metoder

?Development of methods for the planning and implementation of ditch clearing with modern methods?, is a long title for an exam work but that is what this report describes. In Sweden, we have a limited area available, and with the present development with increasing market oil prices, and enormous forces on the renewable energy sources, we need every hectare possible to protect the output of the forests. So with this in mind, many people are now considering how to increase the production of the forests that are already available. A part of production increases is to manage the existing forests, and not to allow this area to go to cultivation or become marshland. We manage our forests in a way that benefits the environment, and we consider that our working practice over the years has shown us to be correct and well functioning. A part of our way of producing forests is to ensure that we have functioning drainage systems in the forest holdings which we administer. The responsible at Holmen Skog requested a good method to make inventories of the drainage systems of Holmen forests. This Degree Project is about ways to identify and implement drainage systems with modern methods. It deals with authorities regulations, and how they operate in different counties.

3-D handlingar, GPS-styrning och VA-moduler- En ny metod för framtida anläggningsprojekt

Ground construction has to a large extent been dominated by traditional meth-ods during the last 50 years. Although the construction has been changed meanwhile innovations are not accepted. In collaboration with NCC Ltd Region South, I have examined a modern con-struction methodology that has been developed by NCC for future large pro-jects. The method is divided into two central phases. Phase 1 is? Single Pro-duction? which is a preliminary period for ground constructions to come.

Nya renings- och uppgraderingstekniker för biogas

Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.

Biblioteket om biblioteket: En studie om hur den fysiska biblioteksmiljön uttrycker biblioteks verksamhetsidéer

The subject of this thesis is studying how physical libraryenvironments express ideas on the function of the library, asstated in guiding documents. The ?physical library? isdefined as everything inside the library building, andexcludes the library architecture, focusing on things likefurniture, furnishing and the arrangement of physical media.The two questions asked in this thesis are: What aspects ofthe idea of a public library?s function, as expressed in theguiding documents of the library, are possible to study in thephysical library environment? In what ways can theseaspects be studied in the physical library environment?The study of the thesis is divided into two parts, a ?prestudy?and a ?main study?. In the pre-study aspects areidentified by reading guiding documents from differentpublic libraries, and analysing the result together withprevious studies on physical library environments. In themain study three Swedish public libraries (located inHelsingborg, Åstorp and Klippan) are visited, and theirenvironments are studied based on theory on what items andmeans of expression can influence the experience of thelibrary function.The four aspects that are identified in the pre-study areculture, education, accessibility, and development.According to the results of the main study, culture isexpressed in the library environment through aesthetics,education through the environment being inviting andstimulating for studies, accessibility by the environmentbeing inviting, functional and democratic, and developmentby modernity.
