Children with concentration difficulties are to a great extent a problem in schools and therefore it becomes interesting to see how possibilities around these children can appear in pre-school. From a pre-school teacher?s perspective, the study aims to provide a deeper understanding of how outdoor education can influence children with concentration difficulties. The method of the study is a qualitative research run-up with interviews that intends to describe pre-school teachers? views.

En intervjustudie gällande skillnad i resutat mellan två avdelningar vid nutritionsmätningar

BackgroundMalnutrition in hospitalized patients has a high prevalence. This led to an action plan against malnutrition that was conducted in 2012 at Enköpings hospital. This paper investigated the nursing staff perceptions of this project on nutrition and nutrient intake in two different departments, and whether these perceptions differ between departments. MethodAn inductive approach with semi-structured interview was used in interviews with eight persons from the staff of the two departments of the hospital in Enköping involved in the project. Interviews were recorded, transcribed and analyzed by content analysis. ResultsIn the interview material four categories were identified as well as six different subcategories. The different categories were: "Attitude", "Knowledge", "Procedures" and "Workload".

Återväxt av blåbär (Vaccinium myrtillus L.) efter ångbehandling : orsaker till effektiv kontroll

Steam was used as a site preparation method to eliminate unwanted bilberry (Vaccinium myrtillus L.) in the boreal forest. The efficiency of steam to suppress bilberry was compared with prescribed burning and cutting the bilberry. Different combinations of steaming and/or cutting the bilberry were set up to investigate in which way steaming and cutting influenced the sprouting and regrowth of bilberry. The regrowth of the bilberry vegetation was monitored for 40 month. Steam was most efficient in suppressing bilberry.

Stopptids- och avvikelseuppfo?ljning vid la?nga takttider : Fra?n avvikelse till info?rd fo?rba?ttring

High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.

Fra?n passivhus till NNE-hus : va?gen till ha?llbar utveckling

sustainable development by reducing the energy use by EU:s directive of energy efficiency and the UN Convention. The second purpose is to present the technical solutions regarding ventilation and heating system that is being used in passive houses. This was done using 8 passive houses, 4 germany and 4 swedish passive houses. Even the international and Swedish system requirements for passive houses have been addressed in this project. The goal was also to explain how and why the mechanical system in passive houses has developed to the technology used today.

Tur och Retur : en kvalitativ studie om resan genom ett narkotikaberoende

The purpose of this study was to, through the life stories of four women and their experiences, thoughts and feelings according to a life in drug dependency reach an increased knowledge about how a dependency can arise, continue and be brought to an end. The question at issue were: How do a small amount of women describe and comprehend their experiences, thoughts and feelings according to their drug addiction seen through a process perspective. In order to answer that question three themes were investigated: the road into dependency, living as an addict and the road to recovery from dependency and the time that follows. The study followed a qualitative method and the theoretical approach was hermeneutic. The results were analysed through a process analyse perspective, from the view of the chosen theoretical perspectives, social constructivism, experience perspective and a psychodynamic perspective.

Silver och vismut i plaster och färger : Källor till förhöjda halter i slam?

Chemical substances are spread diffusely and uncontrollably as a result of the increased consumption of goods. REVAQ is a certification system that works to reduce the flow of hazardous substances to Swedish treatment plants and to create a sustainable nutrient recycling. According to REVAQ, the yearly accumulating rate of metals should not exceed 0.2% in soil per year. Silver and bismuth are two metals that do not fulfill this requirement. The silver concentration in sludge decreased during the last decade, however the last few years, it has leveled off.

Utredning av variablerna som påverkar storleken på brytspänningen i lindningskopplare

Brytspänningen är den spänning som uppkommer när överkopplingsmotståndet i lindningskopplaren lämnar sitt föregående läge vid omkoppling. Storleken på brytspänningen i lindningskopplaren beror på hur stor läckinduktansen är. Är den inte känd så kan brytspänningen istället beräknas med hjälp av FEM-programmet ACE (internt ABB-program) i samband med Mathcad. I ACE beräknas först reaktanserna i p.u-enheter mellan lindningarna och hur stora de är beror på lindningslayouten. Det är tidskrävande att använda ACE och Mathcad och uppgiften är att utreda de parametrar som påverkar storleken på brytspänningen samt att ta fram en förenklad beräkning av densamma.Genom simulering i ACE av en mängd olika lindningslayouter visar det sig snart att det är alltför många parametrar som påverkar reaktanserna.

Om anhöriga och relationers betydelse vid psykossjukdom i det psykoterapeutiska arbetet

The purpose of this study is to better understand patients suffering from psychotic illness along with their family members, and to identify treatment factors that have been helpful for these patients and their families by investigating how their relationships have been affected by treatment. In this way, treatment methods can be put in a theoretical context, treatment efforts can be clearer, and the therapist can develop professionally.The research method used is a semistruktureted interview conducted with tree patients and their families. One conclusion one can draw in the successful treatment with psychotic patients is strongly based on the therapist?s ability to build a safe and secure treatment alliance with both the patient and his family members. Meeting with patients in situations outside of the therapy room have been of great importance for the therapeutic process.Important themes for recovery that come forth during the interviews with the patients are the quality of the therapy session as healing factor.

Membranbioreaktorteknik- en framtida lösning på Lundåkraverket? : Membrane bioreactors- A future solution at Lundåkra wastewater treatment plant?

Membrane bioreactors (MBR) combined with biological phosphorous treatment (Bio-P) has been investigated if that could be an alternative to the future expansion with conventional active sludge treatment at Lundåkra wastewater treatment plant (WWTP) in the proximity of Landskrona, Sweden.The results showed that the surface demand in the biological treatment will be reduced with 67% with the MBR-alternative compared to a conventional activated sludge process. The nutrient removal in the MBR-solution was decreased or unchanged for nitrogen-, phosphorous- and organic parameters. However, the energy demand will increase with an estimated cost of approximately 1 million SEK annually. Moreover, the extra chemical consumption is estimated to cost 370 000 SEK annually.The disturbances caused by filamentous bacteria such as sludge dispersal could be resolved with MBR-technology because the membranes are not affected by these organisms. The Bio-P process combined with MBR-technology works if the wastewater recirculates from the membranes to an aerobic zone.In the proposal, there will be a new pre-treatment step, for instance hole screens.

Potential för värmeåtervinning från mjölkkylanläggningar

The present climate discussion has made energy efficiency an interesting topic. Saving energy does not only help the climate but also saves money for the energy consumer. The purpose of this thesis was to examine the potential of heat recovering from milk cooling. Two milk farms, one with voluntary milking system, VMS, and the other with conventional milking system was used to measure interesting temperatures and electricity consumptions. The numbers were used both to do theoretical calculations and to construct a SIMULINK model. To calculate the potential for heat at milk farms theoretical calculations were made in MATLAB using a reference farm with different combinations of heat recovery and pre cooling. The farm was assumed to keep a dwelling house with the annual heat consumption 18165 kWh.

Optimerande av gasanläggning - genom värmeåtervinning och förlustreducering. Gässlösa Reningsverk

The municipality, of Gatukontoret in Local government of Borås has in the long run, a required need to look after the current heating devices (the gas production plant) in sewage treatment plant, called Gässlösa. The practical work of the examination is about, trying to find a better way to take care of the current heat recovery. That may be one way or another, rather easy to implement in the existent construction.Through the work to increase the efficiency of the gas engine, implement of some external cooling system by heating exchange device. That gives an opportunity to heat (primary) the digester, (but even all internal public areas) with its own superfluous heating.The report shows that if the management group may invest 422 704 crown to implement a heat exchanging device, it gives more space to reduce the need to buy expensive external energy. Gatukontoret´s pay off time, for buying machines, is 20 years, with reservation to calculate with 4 percent internal interest, leads to the yearly mount of 31103 crowns.If Gässlösa increases the gas engine time in (effective) duty approximately (correspondingly) 48 hours a month the entire investment will generate a profit in January in year seven after the implementations.

The influence of forestry stands treatments on brown bears (Ursus arctos) habitat selection in Sweden ? an option for Alberta forestry?

The brown bear population in Alberta, Canada has been decreasing, while the Swedish has been increasing and all the affecting parameters are not known. This study examined the difference in these populations to see if an explanation could be found in differences between the forest management. The aim of the paper was to see if stand treatments had an influence of brown bears habitat selection in autumn in Sweden and how the results can be used in Alberta. This was done by analyzing bear positions in Sweden with forest data, and comparing forest management data for the study area in Sweden with forest management data for Alberta. The results displayed that mature forests over 60 years that have been commercially thinned are selected by bears rather than forests over 60 years that have not been commercially thinned in.

Förebyggning av utbrändhet på organisatorisk nivå

The workplace is for many associated with joy and commitment, for others it is associated with fatigue, inadequacy and cynicism that is explained as the three dimensions of burnout. A general view of burnout is that it is an individual problem that many companies ignore, because a preventive task does not generate immediate profits. This has been a growing problem for years. Burnout costs not only money but also time and knowledge. Unfortunately, the popular belief is that "If it ain?t broke, don?t fix it." Organizations that think this way are sacrificing future benefits for short-term gains.
