Basmobilen

Today?s cell phones include more and more functionality, it is no longer uncommon to be able to connect to the Internet or take photos with the cell phone. In this thesis the question is if the cell phone users are interested in this new functionality. Are there people who are interested in a cell phone that in this thesis is called ?Basmobilen? (the entry level phone), which include the following functions; phone call, SMS, phone book, calling lists, clock and the possibility to change the call signal.

Med fokus på slutet av tunneln : anhörigas upplevelser av sin livssituation i den akuta fasen av allogen stamcellstransplantation

Syftet med den här undersökningen var att beskriva hur anhöriga upplever och hanterar sin livssituation, med fokus på familjen och deras egen hälsa, under den akuta fasen vid allogen stamcellstransplantation. Undersökningen ägde rum på Centrum för Allogen Stamcellstransplantation vid Karolinska Universitetssjukhuset Huddinge. Sju anhöriga till patienter som genomgick en allogen stamcellstransplantation deltog. Metoden som användes var att genom semistrukturerade intervjuer låta anhöriga själva berätta om sin livssituation. Dessa intervjuer analyserades sedan med hjälp av kvalitativ innehållsanalys vilket resulterade i att temat den nuvarande situationen formulerades.

Prestationspåverkan av flerträdshantering i klena gallringar

The aim of this study is to investigate how multiple tree handling harvesters perform compared to earlier developed standards. The study shows that multiple tree handling harvesters are more efficient in thinnings stands with mean stock volumes less than 0,12 m3fub per stock. The increased efficiency is different for different mean stem classes. In stands with a mean stem volume of 0,04 m3fub per stock, the increase can be as high as 40 percent while it is about 10 percent in stands with a mean stem volume of 0,12 m3fub. Comparisons have been done between stands that are felled with partly limbed stands and stands without partly limbed assortments. The difference in performance is clear and shows that the partly limbed assortments strengthen the multiple tree handling harvesters positive effects in low dimension thinnings.

Förbättring av utnyttjandegrad i robotcell

When a company in the manufactory industry makes costly investments, it's important that these are used as much as possible. The company in this case claims that their invested robot cell, with CNC machine isn't used enough. The questions here are: How can we improve the use of the robot cell? Which products are appropriate for the production in the robot cell? As a method to come to a conclusion, an analysis has been made over the manufactured products. And also interviews with machine operators and the production management.

Utbyte av massaved och biobränsle i några typbestånd av Contorta :

The aim of this study is to describe a number of type stands of lodge pole pine in Norrbotten with respect on stem volume and total biomass. Further questions to answer is if there is stand characteristics that make the stands more suitable for pulpwood in early thinning, or if it is better to apply whole tree harvest. The study shall also give an indication if bio energy can be an economical interesting alternative for Sveaskog. Sampled trees represented the variation in the different stands. Five trees were selected from each stand to represent that stand. Stem volume and biomass (kg dry weight (DW) per hectare) for each fraction was calculated.

I väntan på en ny njure : Individens upplevelse

Kronisk njursvikt ökar varje år och vid terminal njurinsufficiens ses njurtransplantation som förstaval av behandling. Behovet av donerade njurar är större än tillgången, vilket leder till en lång väntan för individen. Studiens syfte var att beskriva individers upplevelser i väntan på en njurtransplantation. Metoden var en litteraturstudien där tio vetenskapliga artiklar granskades och analyserades. I analysen framkom tre teman som utgjorde resultatet: behandling för att överleva där dialysbehandlingen sågs som en begränsning i livet och gjorde det svårt att leva som dem gjort tidigare, känna hopp där en transplantation var något att hoppas på, ett sätt att ta sig ur dialysen och få tillbaka sitt gamla liv, samt känna hopplöshet där rädsla för att njurtransplantationen aldrig skulle bli av och känslor av att vara på is i väntan uppkom.

När njuren sviker : Patienters upplevelse av dialysbehandling och väntan på transplantation

Bakgrund: Antalet patienter i behov av njurtransplantation per år är cirka 400-500, varav endast cirka 350 kommer att bli transplanterade. Bristen på organ är tydligt framträdande. I väntan på transplantation behöver patienten dialysbehandling, vilket ofta upplevs vara tidskrävande och utmattande. Sjuksköterskor bör ha kunskap om patienters upplevelser i samband med väntan på transplantation för att kunna utvecklas i sin roll som sjuksköterska och få en djupare förståelse för deras situation.Syfte: Syftet var att beskriva kroniskt njursjuka patienters upplevelser av att leva med dialysbehandling och väntan på transplantation.Metod: Studien är en litteratursammanställning av tio kvalitativa och kvantitativa vetenskapliga artiklar inom området, vilka har granskats, analyserats och sammanställts.Resultat: I resultatet framkom flera olika upplevelser, så som längtan efter frihet, utmattning, höga förväntningar, frustration och rädsla inför framtiden i samband med dialysbehandlingen och väntan på transplantationen.Slutsats: Kroniskt njursjuka patienters upplever sin situation som psykiskt, fysiskt och socialt påfrestande. En av sjuksköterskans viktigaste uppgifter i samband med bemötandet av patienter under dialysbehandling är att vara tillgänglig.

Ultraljud som diagnostiskt hjälpmedel vid subklinisk mastit hos ko :

This study was performed to investigate the possibility to use ultrasonography as a diagnostic tool for sub-clinical mastitis in dairy cows. Five cows with high cell counts, and four cows with low cell counts were selected as cases and controls, respectively, and their udders examined with ultrasound during a 5 week period. The image of the udders of cows with high cell counts exhibited small, hyper-echoic, rounded foci, approximately 1 cm in diameter, near the milk cisterns and the base of the teats. These changes were not found consistently in all cows with high cell count, however. Ultrasonography may be a valuable complementary tool in the diagnosis of sub-clinical mastitis in dairy cow, but more cases need to be monitored before its full value can be ascertained..

Tre metoder för diagnos av mastit i fält :

The objective of this work was to evaluate and compare three field methods for detection of mastitis, California Mastits Test (CMT), DeLaval cell counter DCC (DCC) and FMA2001 Farm Milk Analyzer (FMA2001). Furthermore, to investigate at what cell count level clinical symptoms of mastitis are seen, and finally to check if the clinical findings and cell counts could be related to bacteriological findings. DCC and FMA2001 are new analytic instruments to be used on dairy farms for detection of mastitis. CMT has been a widely used cow-side-test of milk quality in mastitis control efforts, but it cannot be used for estimating cell counts in scientific studies or investigations. Two hundred and eight quarter milk samples from 52 cows were analysed with DCC and CMT, and 168 of these samples with FMA2001. Microbiological examination was done on 38 milk samples with CMT scores of 4 and 5.

The control of the cell cycle with particular emphasis on the G1/S transition

Tumour development occurs to a large extent because of dysregulation of the cell cycle. Of particular importance are defects occurring in the G1 phase. The reason why G1 is critical is because of the influence of several signals (external signals as well as cyclins and cdks) on this stage. The G1 phase can be divided into two parts, G1pm and G1ps. Each part has its ?own? restriction point which needs to be passed in order to progress to S phase.

Röjningsförbandets betydelse för avverkningsekonomin i södra Sverige :

The aim of this work is to demonstrate how the net present value (NPV) at the time of the first thinning depends on the spacing after pre-commercial thinning, and show how net value from first thinning in same stand is influenced. This study is performed with models based on non-distant dependent growth models for single trees. Two different growth models have been used, one for cleaning (pre-commercial thinning) and one for thinning. The first one yields stem density distributed over diameter classes. In the second one, (the thinning model), it is possible to choose when thinning should be done, the thinning method, thinning grade and numbers of thinning.

Investigation of Syndecan-1 Ectodomain Isolated from Chinese Hamster Ovary (CHO) Cell Culture Medium

Syndecan-1 is a cell surface proteoglycan which participates in cell adhesion, differentiation, motility, morphogenesis and intracellular signaling. The two glycosaminoglycans heparan sulfate and chondroitin sulfate are covalently attached to the ectodomain of syndecan-1 via a tetra saccharide linkage sequence. However, the ectodomain can be modified having only one or neither of the glycosaminglycans attached. The glycosaminoglycans are capable of binding ligands such as fibroblast growth factors (FGFs) and support activation of receptors. The ectodomain is proteolytically cleaved from the cell surface by metalloproteinases in a process known as shedding.

Påverkar tidighetstyp fiberhalten hos rödklöver?

The high feeding value of red clover makes it into an important species in Swedish agriculture. There are three different maturity types grown in Sweden, early, medium late and late. The time for heading, regrowth and winter hardiness is affected by the maturity type, but there can also be other factors that are affected by the maturity type, for instance fiber content. In a greenhouse experiment three red clover varieties of different maturity types were compared; early Titus, middle late SW Nancy and late SW Torun. The features compared were fiber content and differences in development rates.

Fotodynamisk terapi vid behandling av skivepitelskarcinom hos katt :

Photodynamic therapy is a relatively new treatment for superficial squamous cell carcinoma in cats. There are no publications indicating that the method is being used in veterinary practice in Sweden at the present time. The method uses the interaction between a photosensitive agent which has been administered to the tumor area, light of a wavelength that can be absorbed by the photosensitiser and the presence of oxygen. In this study photodynamic treatments were performed at the Queen?s Veterinary School Hopital of Cambridge University between 1998 and 2002.

Bränsleceller i personbilar : En teknoekonomisk well-to-wheel analys av vätgas som fordonsbränsle

Several technical solutions are ready to step forward as the new generation of propellant, and this report aims to explore the possibility of commercializing fuel cell cars. The report is based on current research and data from today's technology and engineering solutions that are estimated to be commercially realized before 2020.A mapping of today?s different fuel cell options has shown that the most suitable fuel cell option is the Proton Exchange Membrane Fuel Cell, which uses hydrogen as fuel. The report is focusing on a techno-economic well-to-wheel analysis of hydrogen and the energy balance and costs in a system perspective. The basis for this analysis consists of two centralized methods of production, steam methane reforming (SMR), and alkaline water electrolysis.
