The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.

The aim of this essay is to examine the supervisor?s view on the structure and content of the tasks given to students during their vocational training. The investigation could be of help for teachers when devising new vocational training tasks. The study is based upon qualitative interviews with five supervisors, all of whom work at preschools. The supervisors were asked to grade all the vocational training tasks on a scale from one (easy) to five (difficult).

This is a graduation project in Innovation Management, which seeks to enlighten new theories within the major subject ? the multi?faceted innovation process.The reader is hereby invited to an insight in the more complex perspectives of these types of theories than what has previously been explained in simplified ways.We have conducted research on a company within the cleantech market; Cellkraft AB. The company develops and produces fuel cells amongst other products, which have emerged during their research and development in the fuel cell technology. Cellkraft works in a high?tech frontline market where innovation is key.

As demand for renewable energy is increasing rapidly, the market for biomass pellets is expected to continue to grow in the near future. Most of the new raw materials that are discussed for pellet production have one thing in common; the production costs will increase compared to using traditional raw materials such as sawdust and planer shavings. The aim of this thesis is to investigate to what degree increased use of new raw materials for pellet production will affect the general pellet prices in Sweden and to survey what plans Swedish pellet producers have concerning new raw materials. To investigate the raw material situation of the Swedish pellet producers an industry survey was performed. Literature studies were also made on previous research in the subject field. Calculations of the production costs for pellets were done for the raw materials sawdust, wet sawmill chips and energy wood respectively. New raw materials are already used by the large-scale pellet producers in Sweden.

Background: Sweden is one of many countries which have a long history of immigration during the past decades. Each yearSweden receives numerous immigrants from different parts of the world, which has madeSweden to a multi-culture country.Aim: The aim was to describe nurses? experiences of encounters with patients from different cultures.Method: A literature-based study based on qualitative research, nine scientific articles were performed.Result: The analysis of the data resulted in four themes such as; insufficient communication, family members as a link to the patient, unfamiliar situation, and attentive to the patients? vulnerability with seven subthemes.Conclusion: For a well functioning encounter between nurse and patient from different cultures, a prerequisite is that the nurses establish a relationship based on good communication with the patient and relatives. This can prevent inequality, suffering based on lack of nursing, violation and misunderstandings..

Denna studie undersöker det tolkningsutrymme som kan komma att uppstå på grund av oklarheter i förfarandet vad gäller tillfälliga samarbetskonstellationer. Studien är en fallstudie av kvalitativ art och empirin har insamlats med hjälp av semistrukturerade intervjuer. Fallet består av en samarbetskonstellation och dess beslutsprocess inför en eventuell etablering av en dryport i kommunerna Bjuv och Åstorp. Studien påvisar att det finns oklarheter som har lett till ett tolkningsutrymme var i de olika aktörerna ges möjlighet till att behålla och utveckla sina egna tolkningar av det aktuella problemområdet. Detta har i sin tur lett till att aktörer som i konstellationens början kände sig tveksamma till projektet har ändrat uppfattning och fått en mer positiv syn på situationen.

The economic situation in the Swedish agricultural industry is currently experiencing a development towards larger units. This progress occurs simultaneously as farmers in cooperation more frequently make investments to decrease risk exposure and to improve the financial result. The purpose with this thesis is to study which advantages and problems a group of farmers experience after a common investment in a small-scale seed production. The aim with this investment is to increase the level of vertical integration in their respective agricultural firms and the results will be analyzed from an economic point of view. At present, the farmers are all seed producers with considerable cultivation areas.

This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.

We are always surrounded by space, not just only in a room with four walls, but also when we are outdoors.Constantly we move in a flow of space that changes whenever we move. Unaware we are affectedby this threedimensional surrounding of ours, and it reacts with our perception. Many times, we chooseto translate it into something two-dimensional, for example when we take a photo, recording a movie orframing a view with a window. It helps us to catch a moment, a piece of reality and restore it in our ownway. In this project I?ve chosen to explore this process, to interpret and create my own theories about thistranslation from space to a two-dimensional surface.

Durban, South Africa?s third-largest city is a socially segregated post apartheid society, struggling with high unemployment and AIDS. The city becomes even more complex with a changing climate, creating an influx of people to the city, putting scarce resources under further stress. Warwick Junction, an important transport hub in the centre of Durban, holds a large site of informal trading alongside the formal markets. This informal sector generates large financial flows and provides for a rapidly growing population. The aim of this thesis is to develop an approach that is realistic and relevant to planning and design of an urban context in South Africa.

Långvarig smärta är en av de vanligaste orsakerna till sjukskrivning i Sverige. Många olika typer av rehabiliteringsprogram har testats under årens lopp, med både positiva och negativa resultat. Tidigare studier utvärderar ofta rehabiliteringsperioder från en månad upp till flera månader. Det är intressant att se om en kortare rehabiliteringspeiod kan påverka viktiga faktorer som kopplas till långvarig smärta. Syftet med denna studie var att undersöka om en kort rehabiliteringsperiod kan ge en ökad hälsorelaterad livskvalité, en högre self-efficacy och en lägre rörelserädsla.

The purpose of this thesis is to try to understand, with the help of existing theories and empirical findings, the parameters which are of importance in the development of the pricing capability. We have used a qualitative and abductive methodology approach. The empirical findings have been collected via semi-structured interviews which we have conducted via personal and telephone interviews. Seeing pricing as a capability within the company our theoretical framework mainly consists of the resource-based view and an article explaining and given proof how pricing can be seen as a capability. We also describe the most used pricing strategy today within business-to-business companies, the cost plus strategy.

Background: Today, It?s not uncommon that international companies and organizations have a higher turnover than the GDP of developing countries. Consequently, this may suggest that the choices companies make in the context of their business has a great potential to influence the world from an economic, but also from a social and environmental standpoint. From this the notion emerged that companies have a responsibility, referred to as Corporate Social Responsibility (CSR). A clear definition of the CSR concept is difficult to find, more than 37 different definitions has been identified.

The aim of this study was to examine if transformational leadership, transactional leadership, gender, educational level, income and age predict work motivation, referring to Herzberg?s motivation-hygiene theory. According to past research the factors above increase work motivation. The study was brought about with a survey based on the Multi Factor Leadership Questionnaire (MLQ-5X), Herzberg?s motivation-hygiene theory and demographic items.
