The soil acidification and the pH-value of the soil have been discussed for many years. Many observations of the tree species effects on the soil pH have been done. We have discussed the effects on the soil surface pH-value with a birch (Betula spp. L.) admixture in Norway spruce stands (Picea abies L.).We have used data from the Swedish National Forest Inventory. We have also discussed how the wood production and the biodiversity can be increased in mixed stands, in according to the Swedish forestry act Skogsvårdslagen. Our sampling areas are located in Norrland, Sweden. The results show a significant correlation between an increased birch admixture and an increased pH-value of the soil.

This report is written on the assignment by Nexans IKO Sweden AB in Grimsås which is a cable manufacturing company. Nexans IKO Sweden AB was in need of help to examine possibilities for saving energy by saving compressed air, in first place by using the compressed air more efficient. The task was to determine the present situation, making the airwipe stations more efficient by reducing the consumption of the compressed air and in turn save money. Even the aspects of the working environment were discussed as the noise levels from the pneumatic systems and engines are usually high. A schedule over the airflow in the factory and the inventory over current airwipessituation was made.

With a changing climate, we can expect higher temperatures and more precipitation in Sweden.As the temperature increases, new weed species are expected to migrate in from more southerlylatitudes, resulting in requests for new techniques for weed control. In addition, we might see agreater number of weed species and higher biomass production due to increased concentrationof CO2 in the atmosphere.Increased understanding of the biology of specific weed species will become more importantin future weed control. This will help to control the weeds more efficiently. Higher prices onpesticides and a public demand for reduced use of pesticides make growers more inclined to usemechanical weed control on a larger scale and to a greater extent prevent weed establishmentbefore sowing. A well-planned crop rotation is the most important preventive measure, whichmight also include delayed sowing, and dark harrowing and sowing.Research takes place on many levels within the weed area and several alternative methodsare being developed.

The county administration asked LKAB to make an inventory of possibly contaminated sites caused by their mining activity. The inventory should be performed according to the MIFO model, a method from SEPA which is used to assess a contaminated site. The first phase involves collection of information through interviews and site inspections and in phase 2 a general survey with field sampling is conducted. LKAB started the work with the first phase of the survey during 2003. During this project the information collected in Phase 1 was evaluated and 16 of the sites were chosen to proceed to MIFO Phase 2 (six sites in Kiruna, and 5 sites respectively in Svappavaara and Malmberget). The sampling of these 16 sites was performed during week 27 2004.

Genom webbaserade enkäter har data insamlats för att undersöka huruvida det finns en korrelation med de olika personlighetsdragen inom The Big Five och olika dimensioner av prosocialt beteende. Till detta utformades en enkät genom sammanslagning av Ten Item Personality Inventory (TIPI) och Prosocial Tendency Measure (PTM), där index togs ut för alla olika dimensioner. Respondenter rekryterats genom ett tillgänglighetsurval (N= 79, varav 24 stycken män, M= 39,6 år, SD= 13.6, 55 stycken kvinnor, M= 40.1 år, SD= 13.6 ). Totalt av urvalet var 13,8 procent uppvuxna i en storstad, 28,8 procent uppvuxna i småstad och 57,5 procent inom landsbygd. Inom urvalet hade 10 procent en grundskoleutbildning, 38,8 procent gymnasieutbildning, och 51,3 högskole- eller universitetsutbildning.

Är poliser mer spänningssökande än andra? Det är frågan som ligger till grund för studien där syftet är att jämföra poliser med lärare i vilken utsträckning de söker spänning. Studien genomfördes med hjälp av ett frågeformulär bestående av 28 påståenden som kommer ifrån redan vedertagna skalor. Dessa är Eysenck Personality Inventory och Zuckerman?s Sensation Seeking Scale.

In Sweden the breeding organization for the Swedish Warmblood horse uses a traditional scoring system when evaluating horses. The horse is scored subjectively in relation to how good each trait is in relation to the breeding objective. Other countries, for example the Netherlands, instead use a linear scoring system. The linear scoring system evaluates the horse on a scale between two, for the breed, biological extremes which makes the evaluation more objective since the judges personal values does not influence as much. The breeding organization for the Swedish Warmblood is today planning a change towards a linear scoring system.

The aim of this essay was to investigate how social workers, within chosen Social services districts in the northwest of Skåne, work with children placed in foster care. Our purpose was to investigate the interaction between the child and the foster home from the perspective of the Ecology of Human Development. Our questions were:* How do the social worker prepare the child and the foster home before a placement?* What kind of support is offered to the foster home with the purpose of supporting the child?* How do the social worker make the childs contact with the biological parents easier?* To what degree does the social worker work on strengthening the child's network?* Which factors do the social worker decide the allocation of support?* What do the social worker think affects the work with the foster home from a society level?To answer our question we have interviewed nine social workers. We found that the social workers were generally good at perceiving how the micro- and meso-systems, and to a certain extent the exo-system, influenced the foster child.

Syftet med studien var att undersöka om det finns samband mellan arbetstrivsel och personlighet samt arbetstrivsel och kvaliteten på sociala relationer i arbetet. För att mäta arbetstrivseln och sociala relationer på arbetet formulerades sex frågor som var avsedda att mäta i vilken grad deltagarna trivdes på arbetet och hur de trivdes i sin arbetsgrupp. För att mäta personlighet användes Ten-Item Personality Inventory som är ett personlighetstest utvecklat utifrån femfaktormodellen som innefattar fem olika personlighetsdrag. Det insamlade datamaterialet bestod av 57 besvarade enkäter från undersköterskor på tre kommunala arbetsplatser. Resultatet visade på ett signifikant positivt samband mellan arbetstrivsel och sociala relationer på arbetet.

The aim of this study was; from a group of boys and girls description and interpretation of interaction with other young people, personnel and the environment of the youth centre illuminate how the social gender are constructed and maintained at the youth centre. In this study we have tried to analyse the phenomena from an intersectionalistic perspective. Except gender, the analytic category social class have been tried to capture. Our theoretical standing point is social constructivism. Institutionalized structures in our society are constructed by humans, gender is not only a biological construction it is also a man created construction.

The aim of this study was to explore transsexuals? identity formation and experiences related to cross-sex hormone treatment, as well as to become absorbed in the narrative approach. To be able to participate in transsexuals? identity formation, life stories were well suited as a theoretical approach. Life stories can be seen as socially situated actions according to Mishler, where individuals? identity formation can be seen as both identity performances and identity claims.

Botanist Kjell-Arne Olsson inventoried the plant fen ragwort Senecio paludosus 1983 in Scania andfound a big number of locations within Biosphere Reserve Kristianstad Vattenrike. In 2012, a reinventoryof the 1983 survey was carried out to study whether there has been any change in the fenragwort population in Kristianstad Vattenrike since the last inventory. The results show that therehas been no overall change in the number of fen ragwort in Kristianstad Vattenrike, on certainpremises they have increased in number while in others they have fallen. However, the inventoryshows that almost half of the locations with fen ragwort have disappeared during the same period.The main reason for this is that fen ragwort did not manage to competitive with other vegetation,taking in consideration this has been smaller premises with young plants. In addition to competitionother factors such as prolonged high water, grazing and caterpillars from Tyria jacobaeaecontributed to the decrease.

Studiens syfte var att undersöka tränares ledarskap och dess betydelse för elithandbollsspelares tävlingsoro samt om det finns skillnader mellan män och kvinnor. Undersökningsdeltagarna var 116 elithandbollsspelare med medelåldern 21,81 år (SD=3,54) och åtta elithandbollstränare med medelåldern 41,38 år (SD=5,83) från åtta olika klubbar. Undersökningsdeltagarna besvarade enkäter bestående av instrumenten Developmental Leadership Questionnaire (DLQ) och Competitive State Anxiety Inventory-2 (CSAI-2) vilka avsåg att mäta utvecklande ledarskap samt tävlingsoro. Resultaten indikerade att utvecklande ledarskap har en reducerande effekt på kognitiv-, somatisk- och total tävlingsoro samt att utvecklande ledarskap har starkast effekt på kvinnliga elithandbollspelare. Resultaten indikerade även att kvinnliga spelare har högre grad av alla tre kategorier av tävlingsoro oberoende av ledarstil.

To achieve the Government's milestones for 2018, which means that 50 % of food waste shall be separated from household waste and undergo biological treatment (composting or anaerobic digestion).   Hultsfred, Högsby and Vimmerby are three adjacent municipalities of Kalmar, county Småland. During 2012 and 2013 analyzes were performed on their household waste to determine its composition. The household waste is currently collected in one fraction. The work, examines how much food waste the household waste contains. From the amount of food waste, the biogas potential is examined - how much food waste biogas generates and how much energy it corresponds to.   Food waste is broken down by microorganisms under anaerobic conditions (anaerobic digestion) in a biogas plant.
