The Master Thesis work this report is based upon has been conducted in cooperation with Svea Teknik AB. Svea Teknik is a consultant firm which is developing parts of a tunnel boring machine on behalf of Atlas Copco. The machine is being developed to mechanically excavate hard rock by fixating itself in the tunnel and then press a large rotating cutter-wheel equipped with Disc-cutters against the tunnel wall. The Disc-cutters are the tools that are in direct contact with the hard rock and are therefore exposed to extensive wear and needs to be replaced on a regular basis.The purpose of this Master Thesis has been to develop a service equipment that will enable time effective and safe changes of Disc-cutters. The Disc-cutters have a diameter of 17 inches and weigh about 130 kg.

ABSTRACTBackground: Most cases of lumbar Disc herniation are asymptomatic. When symptomatic, LDH may cause a significant physical and mental distress. Initially, most patients are treated conservative but sometimes operations may be required.Aim: The aim of this study was to provide a review of the scientific basis of physiotherapy, including behavioural therapy, as a treatment to lumbar Disc herniation regarding pain, function and the size of Disc herniation in people suffering from lumbar Disc herniation.Method: Four databases were used in the searches of literature. Assessment of the validity of the studies was done with the PEDro-scale and valuation of evidence rate was made according to guidelines made by the Swedish Council on Health Technology Assessment (SBU).Result: Nine RCT-studies were included with a total of 713 participants. The scientific basis is moderate to support a pain reduction and limited regarding improvement of physical function when it comes to physical exercises, including MDT.

Objectives: The purpose of the study was to examine if a pre- and post-operative difference could be seen in self-reported pain disability and self-efficacy among patients undergoing surgery as treatment for spinal Disc herniation in order to improve process of rehabilitation.Method: A quantitative and descriptive design was used. 10 patients awaiting surgical treatment for spinal Disc herniation were included at Akademiska sjukhuset (The Academic Hospital) in Uppsala. Participation was voluntary and the selection was made by convenience. Data was collected using The Pain Disability Index and Self-Efficacy Scale by which the patient would estimate how hindered they felt because of their pain in everyday activities and their self-efficacy to perform everyday activities. This was done the day before surgery and two weeks after surgery.

Uppsatsens syfte är att belysa hur vision, målstyrning och feedback upplevs av omsorgspersonal då de dagligen inte har tillgång till en fysiskt närvarande chef. För att uppnå vårt syfte har vi valt att genomföra en kvalitativ studie,i en mellanstor kommun som aktivt arbetar med vision och målstyrning sedan ett antal år tillbaka. Det empiriska materialet utgörs av fyra stycken intervjuer med omsorgspersonal utifrån semistrukturerade frågor. Våra frågeställningar är följande: Hur upplever omsorgspersonalen på självstyrande enheter implementering och förankring av organisationens vision i sitt dagliga arbete?  Hur upplever omsorgspersonalen på självstyrande enheter att målstyrning fungerar? Hur upplever omsorgspersonalen på självstyrande enheter möjligheten till feedback med en fysiskt frånvarande chef?   Vad anser omsorgspersonalen på självstyrande enheter om chefens närvaro/frånvaro? För att tolka och analysera vår empiri, har ett hermeneutiskt förhållningssätt och en abduktiv ansats använts.

The objective of this work was to compare the environmentally gentle soil scarification technique Huminmix (with possibilities to do track-grinding/HMMspår, long-scraping/HMMlångfläck and mounding/HMMhög) with conventional Disc trencher, concerning seedling establishment and growth of direct seeded and planted Scots pine seedlings. Inventories were made during June and July 2005, in 34 seeded and 6 planted stands from 2000 ? 2004 (1- 5 years old) of lichen- and myrtillus/vaccinum-type in Holmen Skog AB´s district Norsjö in Västerbotten. The Huminmix-technique had been used for HMMspår in the seeded stands and for HMMhög in the planted stands (HMMlångfläck has been used from the year 2006 for direct seeding). The studied stands had been seeded with the same amount of seeds according to stand data.

In this thesis, two studies with different drills were included. In one of the studies two drills were compared: Väderstad Rapid and Väderstad Spirit. In the other study various drills for direct drilling were compared. The study with Rapid and Spirit was placed in two locations with different autumn tillage; one on ploughed land in Uppsala and one on cultivated land in Västerås, both with relatively high clay content. Rapid drills have a single Disc coulter, while the Spirit drills have a double Disc coulter. Various aspects were compared such as aggregate distribution, seed placement, emergence, crop yield and economic outcome.

This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.

In Sweden, reduced tillage usually means non-inversion tillage, where primary tillage is carried out using chisel ploughs or Disc implements. Primary tillage method is mainly determined by the desired soil loosening and the handling of soil residues. The effect of tillage depth was studied in field experiments in Skåne, Väderstad, Uppsala, Örebro och Västerås in different crops; spring oilseed rape, spring wheat, winter wheat and spring barley.The experiments generally had a randomized block design with the treatments mouldboard ploughing, deep chisel ploughing and shallow chisel ploughing, in some cases also shallow Discing and no-tillage. In the experiments the following parameters were determined: seedbed properties, saturated hydraulic conductivity, penetration resistance, number of emerged plants and crop yield (all parameters were not determined in all experiments. Root growth and draught requirement were determined in two separate studies. There were no significant differences between tillage depths in non-inversion tillage in seedbed properties, plant emergence or root development.

Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.

 Alla har någon gång i sitt liv fått belöning för något de har gjort bra, det kan vara allt ifrån att få en klapp på axeln till att få bra betyg i skolan och ofta så går prestation och belöning hand i hand. Belöningssystem används överallt i olika former, medvetet eller omedvetet och det kan vara ett sådant system som hjälper företagen framåt och eftersom personalen är en viktig resurs i ett företag så är det viktigt att förtaget även vårdar de anställda. Belöning och motivation hör ihop eftersom personalen blir mer motiverade av att bli belönade på något sätt. I dagens säljorganisationer är det vanligt att belöningssystem förekommer eftersom säljarna inom organisationen måste vara motiverade för att prestera. På grund av detta så mynnar det ut till vår problemformulering:Hur uppfattas ett belöningssystem som motivationsfaktor av företagsledaren till den övriga personalen?Samt, Hur kan ett sådant system påverka den övriga personalen? I den teoretiska metoden beskriver vi vilket tillvägagångssätt vi haft för att samla in materialet till den teoretiska referensramen.

Due to the requirement for reduced use of insecticides and the lack of competitive mechanical plant protection, you need a scarification with good result. This is often no problem to perform in normal terrain without technical barriers. However, in difficult terrain with large number of rocks and steep slopes, the result would be worse. The purpose of the study is, that in these areas with difficult terrain, to find out the scarified areas quality, describe the non-scarified areas conditions and find out where the limit is for the use of a traditional Disc trencher. Findings indicate that there are usually not the machine that is the limit, but the driver of this.

 Internet har sedan starten öppnat nya portar för kommunikation. En av de allra populäraste just nu är att blogga. Att uttrycka sig språkligt har kommit att bli så mycket mer än bara att använda sig av ord. På bloggen ges möjlighet att tillföra bild, film, färg och att använda olika typografiska medel, såsom att kursivera eller göra text fetstilt. Element som alla bidrar till hur text tolkas.Utifrån fjorton dagboksbloggar och totalt 289 blogginlägg har min uppsats syftat till att undersöka hur framställning på dessa bloggar, tillhörande gymnasieelever, skett.Mina frågeställningar jag utgått ifrån lyder:Hur använder sig gymnasieungdomar av olika uttrycksmedel för att estetiskt och kreativt skapa ett blogginlägg på så kallade dagboksbloggar?-          Hur används rubriksättning, bild, film, färg och olika stilformat på texten för att skapa kommunikation och olika uttryck på blogginläggen?Hur förhåller sig gymnasieungdomars dagboksblogg till den traditionella dagboken vad det gäller utformning och kommunikationsmöjligheter?Genom en strukturalistisk analys, med utgångspunkt hos Jurij Lotman, har jag gripit mig an blogginläggen på olika plan där jag både undersökt detaljer i texten och övergripande utformning.
