Examensarbete utfört på uppdrag av Boliden Mineral AB i Aitikgruvan. Det har sin bakgrund i att malbarheten hos Aitikmalmen varierar kraftigt, upp till 40 %. Detta försvårar planeringsarbetet och således mycket intressant och lönsamt att söka orsakerna till variationen. Examensarbetet syftar således att utgöra en förbättring i verksamheten helt i linje med styrdokumentet, the new Boliden way. Emellertid föreligger stora svårigheter med att spåra malmen genom hela processen varför man i detta arbete har valt att studera sambandet mellan krossbarheten och bergmassans respons på den tillförda specifika energin från borriggen.

Today?s climate changes will probably give rise to precipitation in Sweden, which will cause more floods in Swedish rivers. Many of the Swedish rivers are regulated and have lots of hydro-electro power plants. Higher floods in the rivers will give greater water loads on the dams, which mean that a higher discharge through the sluice gates and in the spillway channels is needed. High discharge of water in a spillway channel can create scour of the material in the channel.

The aim of this study is to investigate how Swedish listed real estate companies use quantitative sustainability measures - mainly sustainability index with a financial focus. Sustainability management is a controversial issue that is used more and more constructive. A sustainable management approach in corporate cunduct is complex and based on a number of aspects of business visions, objectives and daily procedures. The study identifies aspects that are considered relevant in real estate companies where the selection of sustainability indicators is based on the support of scientific research in this field. The study intendeds to clarify how Swedish listed real estate companies have selected aspects and indicators of sustainability management and how these work towards a sustainable development.

This is a literature study in which I investigate if there are scientific studies that form the basis of the Swedish dog world views concerning the spaying of bitches. The positive impacts are said to be reduced problems with pseudopregnancy, reduced risk of pyometra, reduced risk of mammary and uterine tumors, an earlier cease of bone growth, a more active and happier dog and a bitch who is more tolerant of other dogs. The negative consequences are said to be urinary incontinence, increased aggressiveness, lower metabolism and the increased risk of obesity, a more lethargic individual and altered coat.There are studies indicating that spaying reduces behavioral problems associated with heat and pseudopregnancy. Assuming no ovary tissue persists after the procedure, and there is no progesterone production, the risk of pyometra decreases. Early spaying, before the first heat, reduces the risk of mammary tumors.

The aim for this study was to examine betweenship as a phenomenon by focusing on identity. There is not very much research done on betweenship. I have used a qualitative phenomenological approach, based on four qualitative interviews. The four interviewees were all experiencing betweenship. To analyze their stories I used two theoretical frameworks; identity and affinity groups.

Syfte och frågeställningarSyftet med studien var att undersöka effekten av en kortisoninjektion i bäckenligamenten på patienter med långvarig ländryggssmärta.MetodStudien genomfördes utifrån en single-subject experimental design med sex deltagare med långvarig ländryggssmärta. De utfallsmått som användes var smärtskattning (Numerical Rating Scale, NRS), skattad smärtrelaterad aktivitetsbegränsning (Oswestry Disability Index, ODI), skattad rörelserädsla (Tampa scale of kinesiophobia, TSK-SV), rörlighet (Fingertip-to-floor), funktion genom ett dynamiskt balanstest (Star excursion balance test, SEBT), funktionstest (sit-to-stand) och uthållighetsstyrketest (modifierat Biering- Sørensen), samt fysisk aktivitetsnivå mätt med accelerometermätare. Deltagarna genomförde fem testtillfällen innan och fem eller sex testtillfällen efter intervention. Vid sista besöket skattade deltagarna förändring av besvär enligt global index of change. Resultaten analyserades på individnivå genom visuell analys av trender och nivåskillnader i grafer, statistisk analys av graferna genom 2 SD-metoden, i kombination med deltagarnas subjektiva beskrivningar av eventuell förändring.

Bakgrund: En ökad medveten närvaro kring måltiden och ätandet genom mindful eating har i ny forskning visat sig vara en effektiv metod för att minska en rad olika sjukdomar och hälsorelaterade problem samt bidra till gynnsamma hälsoeffekter. Trots detta finns få studier genomförda i en svensk kontext.Syfte: Undersöka och beskriva graden av mindful eating hos en grupp individer på sociala medier i förhållande till Body Mass Index och demografiska variabler.Metod: Deskriptiv tvärsnittsstudie med en kvantitativ ansats. Ett tidigare utvecklat instrument, Mindful Eating Questionnaire (MEQ), översattes och distribuerades som en webbaserad enkätundersökning. Respondenterna rekryterades under en veckas tid genom ett snöbollsurval på det sociala nätverket Facebook. Inklusionskriterierna var att deltagarna skulle behärska det svenska språket, vara mellan 20-65 år och användare av Facebook.

Tillgång till ASI-data gjordes möjlig genom en avidentifierad fil från databasen ASI-Net och omfattade data från elva kommuner i Jönköpings län.

Scana-Booforge is a Swedish company which specialize in heat treatment of various metal. The treatments take place in quenching ovens, where fans are used to circulate the hot air. The fans used today do not have a satisfactory lifespan. This thesis aims to develop a new design of the fans for the quenching ovens, and the goal is that the new fans will bring cost savings for Scana-Booforge.The design development process started with mapping out the environment in which the fans operate, and with analysis of the existing fan structure and damages, in order to establish the cause of failure and of short durability. The performance of the fan were also established at this stage.

Predation is one of many factors that form the structure of the macroinvertebrate community in lakes, wetlands and watercourses. Earlier studies lack an examination concerning how fish- and waterfowl predation affect macroinvertebrates during shorter periods in the spring. I performed an exclosure study in the shallow eutrophic Lake Tåkern which is located in the western part of Östergötland County, Sweden. The experiment was performed during a three week period (1-21 April 2012) when the water temperature was low and the density of migrating diving ducks was high. The experimental cages used included three out of four different treatments; general predation (open cages), bird exclusion (net with mesh size 90*45mm) and no predation (net with mesh size 1*1mm).

The thesis concerns the use of classification schemes for organising resources in subject-based hierarchical search-services on the web. The aim is to investigate the different kinds of classification that are used, which fall into two groups: established respectively new classification schemes. This is attained by studying literature and the websites of each search-service. The prospects for using classification in a web-environment are discussed and divided into three major groups: browsing, control and cross-classification. One question at issue concerns how an established scheme manages to organise web-resources and whether this classification differs from the classification of new schemes and in what way.

The aim of our study is to deepen our understanding of how both social workers and clients describe how user influence within substance abuse care for adults can work. What difficul-ties do they describe meeting, with regards to possibilities to influence the care? To achieve our purpose we had a qualitative approach for this study. It?s based on open thematic inter-views with 3 clients who have substance abuse problems, and with 3 social workers, working at Social Services in Stockholm.

The increased interest in relationship marketing and the potential of the Internet as a platform for relationship building activities have given rise to new ways for companies to interact with their customers, such as services based on a freemium pricing model. Based on the premise that relationships are processes consisting of interactive moments of value-creating activities, value is considered subjective, relative and dependent on the context in which the activity takes place. Value is therefore variable given its context and cannot be pre-defined without nuances being lost. Despite the Internet's given role in societal development, our understanding of what contributes to customers' intentions to build relationships with online services is yet to mature.As the music industry is well established on the Internet, alongside the change in how music is consumed, it is thus appropriate to examine activities in accordance with a freemium based service that distributes music online, since it still lacks in academic understanding.This study aims to provide insights about virtual relations and how online services that provide cultural content should relate to there users as well as contributing to the ongoing academic discussion regarding value and how it is manifested by highlighting contextual impact on relational activities. For a rapprochement of relations to online services in cultural industries, this study assumed a practice perspective.

If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.
