Lastcells applikation : Verktyg för montering av trådtöjningsgivare i lastcell

Ett verktyg för applicering av trådtöjningsgivare har tagits fram på uppdrag av AED AB i Växjö. Verktyget skall användas för färdigställning/slutmontering av lastceller som i sin tur skall användas till att mäta vilka krafter som påverkar en skogsmaskin när denna lastas med sin givna maxlast. Verktyget skall föras in i ett 25 mm brett hål där det skall hålla fast och lägga tryck på fyra trådtöjningsgivare, en i vardera riktning, vilka bestrykts med lim. Verktyget skall hålla ett tryck på tre till fyra kiloPond medan lastcellen värms till 150° C då limmet härdar. Verktyget består av fyra ben, ett i vardera riktning.

The role of mast cells and mast cell mediators in the development of atopic dermatitis in a mouse model

Atopic dermatitis (AD) is a complex, often lifelong allergic disease affecting around 10 % of both dogs and humans. The hallmark symptom is severe pruritus, causing a lowered quality of life. Mast cells (MCs) are known to play an important part of the immunopathogenesis, promoting a faulty T helper cell type 2 (Th-2) response which follows by a production of specific immunoglobulin E (IgE) antibodies towards environmental allergens (Ag). To further investigate the role of MCs and its mediators in the progression of AD, a low-calcemic vitamin D3 analog (MC903) was used to induce AD-like symptoms locally on the ears of two different knock-out (KO) mouse strains. The first strain was Wsh-/- mice deficient in MCs.

Denna studie undersöker hur stressfaktorer påverkar kroppen vid dykning i gruva. Undersökningen genomfördes under en helgs intensivt dykande, för att bestämma lungkapacitet, pulsnivå samt eventuell vätske- och viktförlust hos dykarna. Testerna bestod av vägning, spirometritester och pulsmätningar. Testpersonerna dök mellan ett till tre dyk under helgen. Två av det totala antalet dyk var på 74 meters djup, resterande dyk genomfördes på 36 meters djup.

Molecular testing of raspberry plants infected with tomato black ring virus

Nematode-transmitted plant viruses (such as nepoviruses) cause great economically losses in commercially important plants such as tomatoes, grapevines and raspberries all over the world. To avoid spread of the viruses the interest in mapping the viruses has increased. One of the important nepoviruses infecting European red raspberries (Rubus idaeus) is Tomato black ring virus (TBRV). TBRV has earlier been confirmed in raspberry samples from Belarus by ELISA and the aim of this bachelor degree project was to confirm these results by amplifying, cloning and sequencing the coat protein (CP) gene of the virus. In total eight viral cDNA samples, from two different raspberry samples, were amplified and sequenced.

Utfackningsvägg i fältfabrik : en studie av arbetsmiljö och enhetstider

Construction companies are frequently criticized for high prices and long construction time. At the same time, statistics shows that construction workers are on the sick-list for occupational injuries or casualties more than other groups at the labour market.Skanska built a block of flats with tenant-ownerships in Gävle. The construction consists of concrete walls with in-fill walls in the front. The purpose with this degree project is to perform a risk analysis in work environment with focus on repetitive strain injuries and control the time report for in-fill walls manufactured in a field factory. The result of this project will help to make more realistic cost predictions in the future.This degree project has been performed in cooperation with the construction company Skanska.

Duglighet i industriella tillverkningsprocesser: Fallstudier utförda på Bosch Rexroth

Duglighetsstudier är verktyg som används allt oftare i industriell tillverkning för att beskriva hur ett företags processer presterar i förhållande till bestämda kvalitets- och toleranskrav. Kunskapen om hur processer presterar bidrar till att företag kan fokusera sitt kvalitetsarbete på att minska den variation som orsakar bristande kvalitet. Syftet med studien var att undersöka hur väl olika tillverkningsprocesser på Bosch Rexroth i Mellansel presterade. Detta gjordes genom mätsystemanalys och duglighetsstudier. Bosch Rexroth i Mellansel tillverkar radialkolvmotorer för industrier som kräver motorer med ett högt vridmoment.

Styrr?ntans olika effekt p? bostadsmarknaden - En komparativ studie om hur bostadspriserna p?verkas olika av r?ntef?r?ndringar i stora och sm? st?der.

This quantitative study aims to investigate whether there is a difference in the effect of the policy rate on the price per square meter for condominiums between small and large cities in Sweden. The study encompasses a total of seven Swedish municipalities, of which three located in large cities and four in small cities. Data regarding housing sales and additional variables have been collected for all municipalities, and the price per square meter is the dependent variable in the regressions performed on the dataset, which constitutes the empirical basis of the study. The aim is further to contribute to an increased understanding of how the effect of the policy rate might differ between Swedish cities and why. The results of the study show significant differences in how the policy rate affects the price per square meter in a small city compared to a large city, with the effect being greater in the latter.

Utveckling av en metod och en utrustning för mätning av bränslesprayers rörelsemängd

A new type of device for measuring thev m& ?rate of fuel sprays from a diesel fuel injector has been developed and the various steps in the development are described. The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.

Cystisk fibrosAtt vara förälder till ett barn med cystisk fibros

Background: Cystic fibrosis (CF) is the most common hereditary disease that leads to an early death. Earlier CF was considered as a childhood disease but today the expected age is 50 years. CF affects all the epithelial cells in the body which makes mucus and other body fluids more viscous than normal. The thick mucus leads to among other things respiratory problems and infections of the lungs. Today there is no cure, only medicines that controls the symptoms.Aim: To describe parents experiences living with a child with CF.

Hur arbetsledare främjar den psykosociala arbetsmiljön?

Enligt arbetsmiljölagen ska arbetsgivare undersöka, genomföra och följa upp verksamheten, enligt det systematiska arbetsmiljöarbetet ska detta arbete ske naturligt i det dagliga. Den mest använda modellen inom kartläggningen av psykosocial arbetsmiljö var krav-kontroll-stöd modellen, det har dock föreslagits att det var viktigt att ta hänsyn till ledningsförfaranden för att kunna förstå arbetsrelaterade risker bättre. Forskningsfrågorna i denna studie var hur ledare arbetade med den psykosociala arbetsmiljön och hur det arbetet förmodades påverka medarbetarnas hälsa. Syftet med studien är att ta reda på detta. I denna studie deltog 8 personer med arbetsledarbefattning, erfarenheten varierade mellan 4-20 år, antalet personer de ansvarade över varierade mellan 1-42 personer.

Fördelning av frambensskador på ytliga böjsenan hos galopphästar :

Superficial digital flexor tendon injuries are common causes of premature retirement or pre-longed convalescence periods for race horses. The curve gradient at Täby Galopp race track is very small and most races as well as high speed training are done on the left rein. It is believed that the horses left foreleg is under considerably more strain then the right foreleg when being ridden on the left rein during gallop at high speed. During gallop on the left rein the horse puts its entire weight on the left foreleg when regaining ground contact. The purpose of this study has been to find out, through analyzing the statistics concerning the horses that visited the ATG clinic at Täby during a period between January 2003 and September 2006, whether there is a higher frequency of superficial digital flexor tendon injuries on the left leg rather than the right and if so, can this support the theory that the design of the race track in combination with continuous left rein races can be a contributing cause of these injuries. The result of the study shows that 57% of the tendon injuries occurred on the left front leg and 38% on the right front leg. The difference is not large enough to support the above theory of the underlying cause of these injuries..

For an example, has the use of antidepressant drugs multiplied by six times for the last 20 years.The aim of this paper is to examine experiences of womens´ mental illness and the use of pharmaceuticals. This is looked upon from two different perspectives: the treatment perspective as well as the perspective of female users.

To assess Robert K. Mertons paradigm: 75 years with ?Social Structure and Anomie"

Robert Mertons anomiteori har historiskt fått skarp kritik på grund av sitt svaga empiriska stöd och sina teoretiska antaganden. Vissa har dock menat att det svaga empiriska stödet beror på felaktiga operationaliseringar av Mertons teori. Den här studien syftar således till att studera operationaliseringar i tidigare forskning av Robert Mertons ursprungliga anomiteori som den presenterades år 1938 i Social Structure and Anomie. Först genomförs en noggrann genomgång och analys av artikeln Social Structure and Anomie och den teori som där presenteras. Genom en systematisk litteraturöversikt har sedan 13 artiklar som operationaliserat Mertons teori valts ut och sedan analyserats utifrån de centrala delarna av Robert Mertons paradigm.
