Ensåsengruvan is a mine situated within Ljusdals municipality in central Sweden. Themine was in use from 1984 to 1991 and has since been undergoing a remediation program. Mine tailings from sulfide rich ore is a potential environmental hazard due to its tendency to cause acid waters and heavy metal leakage. Lake Ensjön is situated one kilometer from the mine area. Due to the hydrological conditions it was not expected to receive inflowing water from the mining area.

I studien testades 35 psykoterapeutstudenter för att undersöka sambandet mellan empati och förmågan att känna igen mikrouttryck. Empati mättes med självskattningsformuläret Interpersonal Reactivity Index vars subskalor mätte följande aspekter av empati: perspektivtagande, fantasi, empatisk omsorg samt personlig oro. Förmåga att känna igen mikrouttryck testades med Micro Expression Training Tool. Resultatet visade ett signifikant positivt samband mellan empati och förmåga att känna igen mikrouttryck. Signifikant positivt samband fanns även mellan subskalan perspektivtagande och förmåga att känna igen mikrouttryck, medan subskalorna fantasi, empatisk omsorg samt personlig oro inte korrelerade med förmåga att känna igen mikrouttryck.

Highly polluted urban storm water from e.g. highways can contain large amounts of heavy metals that may cause harm if they are discharged into recipients. To remove the heavy metals a possible low-cost method that does not require much maintenance, could be the use of reactive filters with filter materials consisting of industrial residues or other cheap mineral based materials. Dissolved metal ions are removed by reactive filters through the processes of ions binding to active sites on the surface of the filter materials, or by formation of insoluble precipitates.The ability of CaO-treated granulated blast-furnace slag, iron oxide coated sand, olivine and nepheline to remove seven heavy metals (Cr, Cd, Cu, Ni, Zn, Pb and Hg) from urban storm water was studied. Initially batch experiments were performed where the effect of pH, dissolved organic carbon (DOC) and dissolved ions on the adsorption efficiency was studied.

Welding is a common method for joining of metal or plastic construction parts. This report describes several different weld methods in general terms. The report focuses on the GMAW method, specifically MAG welding.A case study has also been performed for the company Wenmec. The task received from the company was to compare the mechanical properties of joints welded with the tube electrode called Nittetsu SM-3A and joints welded with the homogenous electrode called ESAB Aristorod 12.63. Both types of weld joint were welded with the MAG method with an Argon based shielding gas with 18% CO2.

Inbreeding, the mating of related individuals, has been the one dominating breeding strategy for dog breeders during the last 200 years. However, its negative effects on fer-tility and other fitness traits, a phenomenon called inbreeding depression, have been ignored in the quest of perfect unity in conformation or performance. The purpose of this study was to test the hypotheses that litter size is reduced as a consequence of in-breeding, affected by both the inbreeding coefficient of the dam and the litter and that a rapid increase in the inbreeding coefficient affects litter size more than a slower rate. Data were collected from the Swedish Kennel Club registry of origin. Breeds included in the study were the Bernese Mountain Dog, the Cocker Spaniel, the Golden Retriever, the Rottweiler and the West Highland White Terrier.

The aim of this paper is to analyze aid, grouped into sectors, and its effect on growth in developing countries, to find out which type of aid has had the most positive effect on growth. We compiled a regression analysis based on panel data over 81 developing countries from 1975-1999. In our first regression we considered and group countries by institutional quality, in the other we considered and group countries after regional differences. As a measure on institutional quality we used the KKZ-index. The principal aim of this paper was to find out what kind of aid is the most efficient in its influence on growth in LDC?s.

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.

Har ni någon bra kärleksroman? : en studie av indexering av skönlitteratur vid stadsbiblioteken i Malmö och Mölndal. Have you got a good love story? : a study of fiction indexing at the public libraries of Malmö and Mölndal.The thesis analyses interviews with users of two Swedish public libraries to find aspectsof fiction important to users and consequently to be considered when indexing fiction.Descriptions of a novel by 50 users at each library are compared to the index terms usedfor these novels. For the analysis, the authors propose a model of their own based onAnnelise Mark Pejtesen's AMP system for fiction indexing.

Uppsatsen har sitt ursprung i den aktuella diskussion i media som hävdat att svenska bolag inte använder sig av en tillräckligt hög skuldsättning. Författarna har avsett att testa om så verkligen är fallet, både utifrån antagandet att en optimal kapitalstruktur existerar och genom jämförelse med branschsnitt i USA. Vad beträffar framräknandet av den optimala kapitalstrukturen har två modeller använts, båda framtagna i enlighet med Aswath Damodarans teorier i ämnet. Den ena tar sin utgångspunkt i att minimera företagets WACC medan den andra utnyttjar en APV för att maximera bolagsvärdet. Jämförbara amerikanska branschsnitt har tagits från Aswath Damodarans hemsida.

Fusarium graminearum is one of the most important pathogens on cereals and causes major crop losses around the world. The most cultivated cereal in Sweden is winter wheat. F. graminearum produces both sexual and asexual spores for dispersal. Multiple factors affect the production of these spores.

Bakgrund: Utvecklingsländernas obligationsmarknad har under de senaste fem åren genererat en avkastning i nivå med aktier. Detta faktum kombinerat bristen på tidigare forskning inom detta område har gjort det intressant att undersöka utvecklingsländernas obligationsmarknad närmare. Syfte: Syftet är att analysera effektiviteten på utvecklingsländernas obligationsmarknad. Genomförande: Med hjälp av informationskvoten och Treynorkvoten undersöks om någon av de tre fonderna i urvalet genererat systematisk överavkastning jämfört med marknadsindexet JP Morgan Emerging Market Constrained Index. Ett signifikanstest på 5 % görs för att utreda om avkastningen är skild från 0.

Problem areaAlfa Laval is a world leading company in the heat transfers area and have the vision to continue to be that in the future as well. The company has a lot of press lines where the utilization is high and also has started to become old. Prognosis shows that there is an increased demand of heat exchanger in the future. This increased demand is not something that existing lines will manage. To build new lines cost a lot of money and take time so it is essential that new lines are correct from the start and not need to be rebuilt or a lot of time spent to trim it.GoalThe goal is to achieve 100% theoretical utilization of the press (the press shall press the amount of plates it is designed for).

Four different kinds of filter-materials with reactive surfaces have been studied concerning their capacity to absorb heavy metals in leachate from a municipal waste deposit. The heavy metals studied were: lead, cadmium, copper, mercury, chromium, nickel and zinc. The leachate contains high levels of dissolved organic carbon (DOC) and has a high pH-value along with a high buffer capacity. These characteristics of the leachate make it difficult to remove pollutants and require efficient filters. The filters that were examined in the report are blast-furnace slag with CaO, sand covered with iron oxides, olivine and nepheline.

Tidigare forskning kring pojkars självkänsla och kroppsmissnöje i relation till massmedieanvändning, extraversion och BMI har utfallit något olika och är inte lika omfattande som forskningen kring flickor. Syftet med denna undersökning var att ta reda på om massmedia, extraversion och BMI har betydelse för tonåriga pojkars självkänsla och kroppsuppfattning. Kvantitativ metod i form av en enkätundersökning användes. Sjuttiotvå gymnasiestuderande pojkar besvarade enkäten som innehöll instrument för att mäta BMI, extraversion, kroppsmissnöje, massmedieanvändning och självkänsla. Resultatet visade att massmedieanvändning inte korrelerar med vare sig självkänsla eller kroppsmissnöje.
