Kartläggning av Sveriges landstings användning av telemedicin

Sweden's aging population makes the need for a viable health care urgent and telemedicine can be a solution to enable older people to receive or give themselves care in their homes. Furthermore, implementation of telemedicine has the potential to realise profits in society by increasing the accessibility of health care and minimizing travel costs. Sweden?s low population density and geographical configuration makes the advantages of telemedicine even more appealing. To illustrate the differences between the county councils? use of telemedicine and thus increasing the possibility for coordinated care between them, the authors have on behalf of the Innovation Centre at the Karolinska University hospital mapped the amount of telemedicine technologies that are available in the Swedish county councils? today. To collect information an electronic survey and video or telephone interviews were used.

Skötselns och ståndortens betydelse för kärnvedsbildningen i tall

Heartwood has always been a desirable part of the tree, due to it?s superior decay qualities com-pared to the sapwood. How the formation of heartwood works has been known for a long time, but which factors that initiates and stimulates the production are poorly understood. This case study presents the results of a study in which silvicultural treatments and site properties had a key position as factors to the formation of heartwood. According to the hypothesis the amount of sapwood is directly controlled by the size of the crown.

Artros - en sjukdom som drabbar både djur och människa, en komparativ studie med kaninen som modelldjur.

SAMMANFATTNING Artros och skador i ledbrosk är vanliga problem hos både människor och djur, som orsakar stora fysiska besvär i form av smärta och nedsatt rörelseförmåga. Idag finns ett flertal olika behandlingsmetoder mot artros, men ännu finns ingen bra behandlingsmetod för att åstadkomma läkning av ett skadat ledbrosk. I den här studien användes kanin som modelldjur för att utvärdera en ny behandling mot artros på människa. Målet var att stimulera nybildning av ledbrosk via rekrytering av mesenkymala stamceller. Studien utfördes på 20 kaniner av rasen New Zeeland White, 6-7 månader gamla honor med en kroppsvikt på ca 4 kg. En ledskada skapades med borr på den mediala femurkondylen i kaninernas vänstra knäled under anestesi. Därefter injicerades en hyaluronsyragel enbart eller tillsammans med tillväxtfaktorn bone morphogenic protein-2 (BMP-2) i leden.

Effektivisering av transporter i gruvindustrin: En studie vid Boliden Mineral AB:s gruva i Kankberg

Marknaderna blir idag, oavsett industri, alltmer globala vilket bidrar till högre konkurrens. Stort fokus ligger vid optimering av produktionen för att minimera kostnaderna samtidigt som att maximera sin output. Logistik har blivit en allt viktigare del av företag vid optimering eftersom det är ett brett område med stora förbättringsmöjligheter för de flesta aktörer. Transporter är en del av logistikområdet som med högre bränslekostnader, krav på förkortade ledtider och minimala kostnader är en viktig del för företag. Boliden Mineral AB, som studien utförts hos, är ett företag inom gruvindustrin som sedan 1924 varit aktivt med säte i Boliden strax utanför Skellefteå.

Simulering av valkar i pappersrullar : och analys av de slappa stråk som uppkommer

A baggy paper web has parts that are longer than neighboring parts. One of the assumed reasons for bagginess is thickness variations of the paper. In the roll the thicker streaks then add up to form a ridge. In the ridges the paper is strained and during storage the strain may become permanent. When the paper unreeled it is then baggy.

Den erfarne ripjägaren : Optimalt födosök hos homo sapiens?

The purpose of this study is to examine some factors that make a human grouse hunter to prolong and increase its hunting effort. The theory of optimal foraging is used for explaining their behavior.The data of this study is collected from a web-based inquiry from 2007 answered by grouse hunters in Sweden. The method that has been used is mainly bivariate statistics and logistic regression analysis.Key findings shows that an experienced grouse hunter has more than 5 times the chance of prolonging hunting effort when grouse density is high, compared to a beginner grouse hunter. On the same time experienced grouse hunters also stop hunting in advance when grouse density is low to a larger extent than inexperienced hunters. Other factors of importance for prolonging the hunting effort for a day are age and the travel distance to the hunting area.

Kortsiktig fosforeffekt av avloppsslam : krukförsök i växthus där järn-, aluminium- respektive kalkfällt slam använts som fosforgödselmedel

The short term effect of phosphorus in sewage sludge was investigated to establish howmuch of this a farmer can grant him- or herself, if using sewage sludge as a phosphorusfertilizer. Possible differences in plant availability between sludge phosphorus precipitatedby iron, aluminum or calcium integrations were studied in a sandy soil at two pH levels.The sludges were analyzed using pot and incubation trials. As the intention was to investigategrowth limitation due to phosphorus deficiency, a soil with low phosphorus supplywas chosen as well as a low phosphorus application rate. Sludge corresponding to 12kg phosphorus per hectare was applied. Treatments fertilized by sludge were compared totreatments where 0, 6 and 12 kg phosphorus per hectare from mineral fertilizer was applied.Every treatment was replicated six times.

Stressfrakturer hos den elitidrottande hästen : potentiella benmarkörer för diagnos och prevention

Muskuloskeletala skador är ett stort problem hos hästar som tränas och tävlas i kapplöpning, och orsakar smärta med påföljande hälta för individen och ger även ekonomiska förluster inom industrin. Av dessa är stressfrakturer i tredje metakarpalbenet distalt på frambenet vanligast och utgången är ofta katastrofal med avslut på karriären och i vissa fall slakt. För denna typ av skada finns alltid en preexisterande patologi i benvävnaden. Träningen är högintensiv och kräver en fysisk adaptation av rörelseapparaten. Den kraftiga mekaniska belastningen kan kopplas till predilektionsplatser för frakturerna, där mikroskador i benvävnad utvecklas till fullständiga frakturer.

Varnhems tidiga kyrka och kyrkogård : Isotopanalys av skelettmaterialet i området

This paper deals with stable isotope analysis on the children of the early Christian cemetery in Varnhem, Västergötland. Human bone and tooth material from the cemetery has been analysed for stable carbon, nitrogen and sulphur isotopes. The analysis showed that the diet had been homogeneous and that the children had been breastfed, with a possible exception of the child from grave 100..

Globaliseringens och professionaliseringens effekter på styrelsesammansättningen i svenska börsbolag: En social nätverksanalys baserad på delade styrelseledamöter under perioden 1990 till 2010

The purpose of this thesis is to examine the networks of interlocking directors in the 50 largestSwedish companies on the Stockholm Stock Exchange during the years 1990, 1995, 2000, 2005and 2010 and seek explanations for the observed developments.Our findings indicate that the density and concentration of the network has decreased during thefirst ten-year period and stayed constant during the second period. The development of theoverall network is not consistent throughout all corporate groups. Most notablyHandelsbankssfären seems to experience increased density and connectivity whileWallenbergsfären is experiencing the reverse.The changes during the first ten-year period is deemed to come mainly from changes inregulations pertaining to both the opening for international capital investments as well as looserrestrictions on domestic capital investments. These changes have caused decreased concentrationof ownership, as well as the emergence of new owners, which is reflected in the board ofdirectors.During the second ten-year period the changes are more pertaining to the individual boards andboard members, without flowing through into the overall network. Our findings indicate thatthese changes are caused by the increased professionalization of boards and board work, whichhas gained momentum through the creation of the Swedish Corporate Governance Code..

Stadsrum och stadsliv - Bebyggelsestrukturers inverkan på kvalitet och innehåll i det offentliga

ABSTRACTToday's modern technological society is constantly evolving and house planning is one area that is constantly creating new technical solutions. By looking back at selected architectural eras during the 1900?s, the idea is to study and analyse three building structures in Gothenburg with a focus on quality and content in the urban space.In order to provide a background for the three selected areas, their history has been studied. The main question for the research is: how do different building structures affect the content and qualities in the urban space?The areas have been selected to represent three typical epochs in Swedish building history.

Vertikal förtätning : En del av ett hållbart stadsbyggande?

This is an essay concerning the density of the city. An increasing amount of today?s cities have a shortage of space available for the erection of new buildings and settlements, especially in areas close to the city-centre. New buildings and settlements are therefore often found in the outskirts of the city, resulting in long distances between work and living for many people. These long distances are a waste of limited resources and are inconsistent with the vision of the sustainable city.The challenge for the future is to insert new buildings and settlements in the existing city-structure and in this way reduce the distances between different city-functions.The density of the city can be increased in two different ways; by inserting new buildings between existing ones or by extension existing buildings, for example by an additional floor.

Pressning och hantering av halm som energiråvara

I?ve tried to find the most effective and cost effective way to harvest straw for energy recovery.You can choose between round bales and big square bales. Square bales are the cheapest way to produce straw for fuel recovery because you can optimize the length of the bales so they fit the transportation equipment.In the Malmö area the average days of harvesting hay is 55. The effectively of transportation depends mostly of the speed, the distance and density of the bales. To increase the capacity of bale transportation larger loads and higher density of the bales is necessary.

Brand Culture : Between consumers and brands

The empirical data that lies behind this survey comes from field work between 1992 and 1995. This field work represents work I made myself as a sales-man for the company, Malmberg Original Water. The task was to implement the Malmberg mineral water brand on the restaurant market of the South-Swedish area. Our aim was to reach the upper-scale, premium market of restaurants. The mission was successfully completed, and at 1996 we had completed the position as the most exclusively positioned mineral water brand in Skåne (Southernmost Sweden).
