Abstract The purpose of the study is to examine how children perceive the relation between play and sex and analyse it from a gender perspective. This by answering the questions: "Is the children?s choice of place, materials and company in play dependent on gender?" and "Is there a significant difference between the sexes and/or ages?" The study was done through twelve focusgroup interviews with three children in each group except two groups of two children in each. Eight boys and nine girls of six years old and nine boys and eight girls of nine years old were interviewed. Boys and girls were interviewed in separate groups and the questions were open ended and followed up.

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 purpose has been to, by the means of literature studies and conversation, give landscape architects, teachers or other interested people an increased understanding of school gardens as a phenomenon. One episode in the essay describes school garden?s historical background and how its ideology has changed as the society has developed. A conversation with a spokesperson for Södermalmsskolan in Stockholm, depict how a communal public school handles the management of a school garden today. I have also wanted to present the conditions that society and the schools organisation has put on the management of the garden on this particular school. In the year of 2007 Södermalmsskolan got the opportunity to found its school garden thanks to the environmental campaigns that were realized by the city of Stockholm.

Volvo Construction Equipment is a world leading company in construction machinery. Tomaintain the best products, development is prioritized. The master thesis regards sound reductionof the hydraulic system on a wheel loader. The background to the master thesis is asimulation made on the hydraulic system, performed autumn 2005. The result of the simulationshows that the energy of the pressure ripple is reduced when the paralleled hydraulicpumps are phase shifted and reduces each others pump pulsations.

AbstractThe term aftercare is largelyexplained by means of the contextual and ideological conditions for treatmentwhich are to be found in juvenile care facilities. The development of the livesof young people who have been placed in care facilities is dependent ontherapeutic relationships, professional separations, continuing follow-ups andan even transition from control to autonomy. The aim of this study was toexamine the steering mechanisms behind the execution and planning of aftercareat a youth facility for care or residence. The aim was further defined throughthe specification of the following questions: 1. How are the concepts ofresocialisation and aftercare define and delimit? 2.

The purpose of this thesis was to find out what experiences teachers have from using a class blog in teaching. What are the advantages and disadvantages by the use of blogs in education?I have used qualitative interviews with four teachers in grades 1 to 6 who have worked with a class blog in teaching between one and three years.The study has shown that teachers' experience is that the blog serves as motivation and promotes learning for many different pupils and that, together with other digital tools is more equal. The main benefits that teacher mention is the expanded concept of text that offers multiple forms of expression and the authentic reader, which makes it more real, important and meaningful. Other benefits that come up are that it helps students to see their learning and learn from and with each other.

Tussilago farfara, coltsfoot, is a troublesome perennial weed with deep lying rhizome, which can vegetatively generate new plants. The mechanical control of coltsfoot that is used today, "starvation", which consists of several cultivations of the soil, which fragmentises the rhizome. This results in production of new shoots, which leads to depletion of nutrient resources; as long the new plant is not allowed to establish. However, very little research has been done to investigate how the starving technique affects the regenerative ability of coltsfoot. The purpose of this experiment with coltsfoot was to investigate how fragmentation and burial depths affect the time of emergence, number of emerged shoots per rhizome fragment, number of shoots per node, and if the germination ability within nodes changes during the experiment.

This study will identify the environmental impact in terms of carbon dioxide for a boiler house on behalf of Kvänum energi. The boiler central consists of a main building, which in turn contains multiple components such as boilers, pipes, etc, the boiler central uses pellets fuel. It also includes a silo and an ash container. The total weight of the boiler is about 63 tons. Each boiler has an output of 600 kW; the central includes three boilers with room for a fourth if necessary.

Chlorinated aliphatic hydrocarbons (CAH´s) were used widely within dry cleaning facilities and for metal degreasing until their toxicity was discovered. PCE is still used as dry cleaning liquid. Today CAH´s are found in soil environment at places where they have been used in the past. The CAH-concentration in trees growing on contaminated land has quite recently received attention as a cheap and effective way of assessing the extent of a CAH-contamination. The method has however, not been put into use in Sweden.The aim of the study has been to investigate whether the CAH-concentration in tree cores could be used to delineate the spread of CAH in a soil environment under Swedish conditions in different seasons.

The economic development and competitiveness in Europe is heavily dependent on an efficient transport system. Movement of goods and people is essential for a competitive industry and successful trade. As a result of an intensified transport business, consumption of fossil fuels has increased dramatically. As a consequence, there are increased emissions of dangerous greenhouse gases. Transports are often mentioned as an area with high impact on the environment.

Bees are of importance for the global food security. In Europe 84% and in the World 35% of all the agricultural crops are dependent of animal pollination (Winfree et al., 2011:1). In agricultural production there is a huge lack of pollinators (Azien & Harden, 2009). A problem that is widely spread. In Sweden the problem becomes clear when looking at the statistics of the number of bee colonies during the last 20 years, where it has been a decline with 63 % (Statistiska Centralbyrån & Jordbruksverket, 2011).

We know that more than 2/3 of insured dogs in Sweden are put to death by a veterinarian, which means that almost one third are killed in trauma, lost or die in some other way. An unknown number of these are killed by their owner with no veterinarian involved. This graduate thesis contains a specification of the laws that control euthanasia of dogs and cats in Sweden, and the veterinary medical basics on how to perform euthanasia. The objective is also to give understanding on how pet owners choose to put their animal to death and why, and to discuss whether that is an animal welfare problem. It is legal to kill dogs and cats by shooting, using a sporting gun, provided that it is done according to laws and regulations.

.The Whole language program is in Sweden generally referred to as ?Kiwimetoden? - ?the Kiwi program? (author?s direct translation) partly due to the fact that the Whole language program originates from New Zealand. Whole language is basically a literacy program and approaches literacy from a holistic point of view. Children learning to read and write should do so in the same natural way children learn to speak their native language which is in the context of authentic language as a whole. In Sweden the program is generally practiced together with a commercial and pre-organised material called ?kiwi? or ?Stjärnsvenska?.

Both the German and the Nordic power markets are seeing dramatically changed conditions due to an ongoing process of expanding the share of renewable production in the systems. For the German part this comes from heavy subsidies which have led to an explosive development in installed capacity of photovoltaic and wind based production. After the Fukushima incident it has been decided to shut down all Germanys nuclear plants. This capacity drop is however not of the same magnitude as the increase in renewables, but will impact the stability of the power system. The Nordic power system which already has a surplus of power sees an even further increase, coming mainly from construction of new nuclear plants in Finland and a general increase in wind farms.

In this paper the effect of capital structure on profitability has been investigated among Swedish companies. The essay intends to examine how the relationship between debt and profitability appear among Swedish companies and if the relationship differs between industries. The purpose is to find out how debt affects the profitability of Swedish companies.A quantitative approach has been applied. The selection was made among companies listed on Nasdaq OMX Stockholm, which resulted in a sample of 207 companies. Several regression analyzes has been formed, based on the independent variable debt-ratio and the dependent variables profit margin, pre-tax profit margin, operating margin, return on assets and return on equity.
