Föräldrars upplevelser av att vårda sitt nyfödda barn på Neonatal Intensivvårdsavdelning - En litteraturstudie.

Background: Breastfeeding frequency decrease in Sweden and infants born preterm is a particularly vulnerable group to not be breastfed according to current recommendations. Mothers of preterm infants have an extra need of support from the health care system. Mothers' self-efficacy in breastfeeding affects the outcome of breastfeeding. Health professionals' attitudes to breastfeeding have an impact on the breast feeding support they provide to the mothers.Aim: To investigate whether an intervention could strengthen self-efficacy in breastfeeding among mothers of premature babies. A further aim was to investigate whether the intervention influenced health professionals' attitudes to breastfeeding.Method/Design: An experimental study with quantitative approach in the form of questionnaire survey was conducted.

Mätning av ekosystemtjänster i jordbrukslandskapet :

Abstract In order to make the modern agriculture less dependent on non-renewable external inputs, it has to rely more on ecosystem services. The agricultural system produce not only food, fiber and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of nutrients, influencing local microclimate, pollination, biological control and detoxification of noxious chemicals. This study is an attempt to get a better understanding about the interaction among different ecosystem services and different habitats capacity to generate them. An evaluation of eight different methods is done. The ecosystem services studied are the ability to absorb solar energy, biomass production, botanical diversity, decomposition and natural predation of aphids.

Vem styr mitt arbete? Förändrade arbetsuppgifter vid datorisering av körschema

Abstract This report is our bachelor thesis. Our work has taken place at a galvanising company in Sölvesborg. The company faced major changes, of which one was a computerisation process. The new system could involve changes in work practice and in specific tasks, affecting the workers. If the coming system was to support work, from the production personnel?s perspective, we felt a legitimate participation in the development and design of the future work practice, was a requirement that was not met. During our ethnographical studies we noted that conflicts arose between production and administrative -personnel.

In recent years, the penetration of new players on the telecom market hasdrastically increased the work pace, affecting both design and production. Inthis report the technical and economical potential of a DC/DC converterplatform is investigated, in order to shorten the time of the design process.This is done in comparison with the present discrete type designs. PowerIntegrations offers a product, the DPA-Switch?, enabling this.By developing a wide DC/DC converter platform based on the DPA-Switch?,many advantages are gained. The component count is decreased by up to48 % and the yield increases by up to 2.9 % which in all yields a costreduction by up to 43 % or ?390 000 for 100 000 manufactured units.

Utvecklingen av ett nytt såghandtag

SNA Europe?s handsaw concept is called ?Bahco Handsaw System? and is constituted by a saw handle with the possibility to switch between different saw blades. The sales of ?Bahco Handsaw System? products have not achieved the desired results probably due to the high price. Developing a more cost efficient handle, enabling a lower consumer price of the product, is assumed to increase the sales volume.

Luftfuktighetens påverkan på konstruktion och klimat i en berghangar

Aeroseum is an aviation museum located in an old military underground hangar. The ventilation system in the hangar is designed for the military purpose of the hangar. This design includes a solution with air flowing through the space between the construction of the hangar and the rock surface. The solution is intended to avoid a buildup of inflammable gases. This design leads too high humidity levels in the hangar.

Nedskrivning av goodwill : I vilken utsträckning redovisas upplysningar om koncerngoodwill i enlighet med IAS 36 p134?

Service Design is a relatively new, unexplored and exciting phenomenon that through an interdisciplinary work methodology designs services. A discussion has been going on for a long time regarding whether there is a difference between products and services. Services are often classified as immaterial, heterogeneous, non-storable and inseparable in relation to products. A question that arises is if something specific characterises the work methodology used regarding service design. The aim with this paper is thus to explain the work methodology when working with service design.

Modellbaserad drivlinereglering

A cars powertrain consists of everything that is needed for its propulsion. The components in the driveline that transfer the power from the engine to the driven wheels are not absolutely stiff, hence they will wind up due to the torque and act as torsion springs. If you suddenly demand a bigger torque by stepping on the accelerator pedal, a so called tip in manoeuvre, and that torque is acquired from the engine as quickly as possible, the driveline will not be able to transfer that fast torque change due to its weakness and as a result it will start to oscillate. These oscillations will be transferred to the driven wheels and make the car to accelerate jerkily which will be experienced as uncomfortable by the passengers. Furthermore, there is a backlash in the driveline that will make the weakness in the driveline even more excited than it should have been if the backlash did not existed.To avoid too big problems with these oscillations there is a control system that controls the demanded torque.

Dynamisk styrketräning av M : Quadriceps femoris hos personer i övre medelåldern

AbstractElderly people are going to be a growing number in Europe. Between one third are going to be 60 years or older at 2025. For Sweden the situation is going to be similar. A reduced muscle function could lead to complications for the individual to perform daily tasks and will lead to a higher rate for falling and getting bone fractures. The positive sides are that for men and women there are a possibility for maintaining physical function and strength even in older years.
