Reflections

Reflections är en stämningslampa som med hjälp av invävd fiberoptik lockar fram nya visuella och taktila uttrycksvärdeni en textil. Under arbetets gång har jag utforskat mängden ljus som fiberoptisk textil sprider längsmed fiberlängden samt undersökt naturfiberns egenskaper när den vävs samman med fiberoptik.En stor utmaning var att hitta balans mellan tekniska begränsningar och det uttryck jag sökte. Lampans formspråkär min reflektion över dagens stadslandskap där arkitekturens geometriska former möterfordons strömlinjeform. Med stämningslampan hoppas jag att hitta och inspirera till nya användningsområdenför fiberoptisk textil.Reflections is a mood light using interwoven fiber optics witch brings out new visual and tactile expressionvalues in a textile. During the work, I have explored the amount of light fiber optic textile spreads along thefiber length and examined properties of nature fiber when it is interwoven with fiber optics.A major challenge was finding a balance between technical constraints and expressions I was looking for.

Konstruktion av serviceutrustning till tunnelborrningsmaskin

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.

Diagnosis of Leber?s hereditary optic neuropathy (LHON) : analysis of MT-ND1, MT-ND4 and MT-ND6 in patients with LHON

Leber´s hereditary optic neuropathy (LHON), a disease affecting vision, is caused by several point mutations in mitochondrial DNA. Mutations leading to a defect NADH ubiquinone oxidoreductase protein will affect the respiratory chain and cause a disturbed ATP production. It is still unknown why this defect leads to the degeneration of retinal ganglion cells and cells in the opticus nerve as well as demyelination of axons in these areas. Analysis of mitochondrial DNA is an important tool in the diagnosis of the disease. At the present time analysis is based on cleavage by restriction enzymes, which only detects two of the most frequent mutations: m.3460G>A and m.11778G>A.

SJUKGYMNASTIK SOM BEHANDLING VID LÄNDRYGGSDISKBRÅCK

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.

Patienters skattning av hindrande smärta och self-efficacy före och efter diskbråcksoperation

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.

Hur vet personalen att den gör rätt sak på den "cheflösa" arbetsplatsen : En kvalitativ studie om omsorgspersonals upplevelser av vision, målstyrning och feedback på den självstyrande enheten

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.

Undersökning av retrobulbärområdet på hund med hjälp av ultraljud :

This study was performed in order to investigate the difficulty in diagnosing retrobulbar disease with ultrasound. A retrospective study was accomplished to investigate the use of ultrasound in patients with suspected retrobulbar problems, and how often the examination is diagnostic. The computer based patient files, at the University of Agricultural Science in Uppsala, were searched for dogs with suspected retrobulbar disease. During 1999-01-01-2004-04-14, 14 patients fulfilling the search criteria were found. The patient records were studied, and the written reports from the ultrasound examinations were compared with the printed pictures from the examinations.

Plantetablering och tillväxt för sådd och planterad tall 2-5 år efter markberedning med harv eller Huminmix-teknik inom Holmen Skog distrikt Norsjö :

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.

Försök med olika såmaskiner vid konventionell sådd och direktsådd

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.

Skarven : ? Produktutveckling av en oljedimavskiljare

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.

IT-supporten i kommunala verksamheter: En fallstudie av Umeå kommun

The objective of this study was to examine how an IT department has been affected by the changes of increased local usage of IT, and how the usage have affected municipalities IT departments demands of IT support. In the study we explore how both the IT department and the IT support works by interviewing present and former employees at the local IT department. The current IT department have undergone a series of local changes over the last 20 years, the department has gone from only having internal users to getting the entire municipalitiy?s agencies of IT as users. It started with how the municipality began to dig down fiber optic cable in the middle of the 1990?s, and today has started to develop solutions as to how to meet the demands of future usage of IT.

Effekter av bearbetningsdjup i plöjningsfri odling

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.

Syntetiska Instrument

This thesis aims to investigate SAAB AB´s possibilities to use synthetic instruments in their test systems. The reason for this is reducing costs and the risk of obsolescence which is common when test systems operate for several decades.The market around synthetic instruments has been explored in the search for suitable hardware and software. Software has been developed in LabVIEW and synthetic instruments have been created with the help of IVI-drivers. The hardware consisted of PXI-instruments (Waveform generator and Digitizer), connected to a computer using a fiber optic link and PXI-chassi. The created instruments was then compared to common instruments used today, and the comparison turned out well.

Förekomst av penicillinkänslighet hos blododlingsisolat av Staphylococcus aureus

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.
