The purpose of this report is to collect, compile and complement the scientific and experience based knowledge concerning high pressure fire fighting today. The goal is to produce a decision data for the Rescue Service concerning the use of high pressure systems for fire fighting. Focus is on hose reel high pressure systems but other systems are discussed too. The report begins by describing the technical properties of the different systems. Then the fire fighting properties are evaluated, including manoeuvrability and safety for users.

In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them. The different languages have their advantages and their disadvantages where some of them are intended for fast performance, some to be cheap on memory usage, and some are developed to be easy to program on. In our thesis we have chosen to compare four of todays most common languages, C, C++, Java and Python.

The students are usually eager to develop their mathematical learning. However, the Skolverket can see that this eagerness passes in the early years of school. A study shows that a varied mathematical education creates enthusiasm to learn, which can decrease the negative view of mathematics.The purpose of this study is to see how five pedagogues use laboratory mathematics, their approaches to laboratory mathematics as well as to find out their role in the laboratory education. The result of the study is based on interviews with the pedagogues, who are all teachers for students in year F-3. All of the pedagogues work in a laboratory way, but to different extents.The study shows that the pedagogues aim to make the mathematics as concrete and everyday as possible.

Swedish students' knowledge of both mathematics and reading comprehension has deteriorated in recent years. Scientists are discussing whether there is a connection between these areas and that the pupils deteriorating math skills may have something to do with their increasingly lower results in terms of reading comprehension. To investigate this possible connection, I conducted a survey among students in ninth grade and have come to the conclusion that the scientists are right: this connection absolutely exist. Students who received a high score on tasks designed to test students' mathematical problem-solving skills, also received high results on the reading comprehension test. And students who received a poor performance on the problem-solving tasks, were also low performers in the reading comprehension test.

In each classroom there is a teacher with good intentions wanting what´s best for their pupils. But grades and tests in mathematics from 2009 in Sweden shows there is a crack between the subject being taught and the learning child. The purpose with this research is to find an understanding from a teaching and learning perspective of which teaching method is more suitable for teaching and learning mathematics by doing a comparison between two methods. The main question is:What are the advantages and disadvantages of the traditional and the laboratory method of teaching, supported by the two keywords teaching method and learning?This C-paper is based on a qualitative research aiming to gather an in-depth understanding of human behavior.

This thesis reports on the methodology and results of a study with one retailers 73 units to investigate factors of the store managers leadership that influence productivity performance in store. The study determine the impact of ten independent variables in terms of the store managers leadership on four performance measures: (3) three productivity measures: Sales Over Labor (SALOL), Sales Over Inventory (SALOI) and Sales Over Square-metre (SALOS) and (1) one profit measure: Contribution Income Over Square-metre (CIOS). The result shows that the leadership factors give no more explanation to the economic results after factors of local market condition and the store attributes are taking in to account. The store manager's leadership can though influence his or her decision-making in-store. The store manager's decision to staff the store more intense (higher service-intensity) can increase the level of contribution income over square metre in-store..

In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.

Comfort analyses regarding human induced vibrationsIt is not too common among civil engineers in Sweden to perform comfort analyses considering the vibrations caused by human activities. In addition, the Swedish standards lack requirements to be used for comfort analyses in design of floor-systems. The demand for large spans in combination with slender slabs, is today a reason to investigate the floor-system constructions, in order to prevent disturbing vibrations and oscillations.The purpose of this thesis is to create a guide for how a comfort analysis, considering vibrations, should be implemented. Göran Svedenbjörk who is an expert in structural dynamics has been interviewed where he presents his latest project Värtaterminalen and answers some questions about vibrations due to human activities.Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied.

The aim of this thesis is to model my artistic practice on an adaptation of Joseph Campbells monomyth and, using this model, investigate challenges of performativity in art (in public spaces). The overall themes are personal, aesthetic and ethical sovereignty and an uncompromising search for a deepening of the artistic practice. More than anything else it is a map and a story of an artist?s expansion out into an artistic field that is little developed in Sweden. It is my hope that this thesis, by using a thoroughly subjective tone, will contribute to the milieu of performative arts in Sweden as well as widen the ?how? regarding the making of a written thesis..

The purpose of this study is to investigate and describe the variation in perceptions of demands and expectations of study performance among a group of students at an upper secondary school. The study is inspired by a phenomenographic approach in which variations in perceptions of a phenomenon are of importance. Twelve students at a science program participated and were interviewed in groups of four. The results show that among the students there are several different perceptions of the demands and expectations to perform they felt present in their lives. The most important result is that it is the students' own demands and expectations on their performance and study results that are seen as the most demanding..

This research analyzed differences in measurements of magnetic field strength and frequency response in five audio induction loops installed in rooms of wooden construction materials and five audio inductive loops installed in rooms of steel reinforced concrete constructions. The inductive loops were installed at floor level and the measurements were made at the listening height of 1.2m. Measurements of background noise, field strength and frequency response were made at fifteen different measurement points across the room. The research measurements showed that there are differences in field strength and frequency response between these two conditions, whether the audio induction loop is installed in a wooden construction or the audio induction loop is installed in a reinforced concrete construction. The results had a significance level of p=0,05..

During the milling of Sandvik Coromant?s world leading Drill with replaceable inserts,the CoroDrill880©, burrs appear around the milled surfaces. The burrs are removedusing different methods, one of which is deburring with special brushing machines thatare integrated into milling cells. The machines of the type Sinjet, use a Siemensguidance system. The deburring results are not satisfying and manual deburring isrequired afterwards.

ABSTRACTProblems with high turnover in nursing has escalated during the last years both nationally and internationally. according to previous research job satisfaction and quality of care was connected to specific features of the hospital work environement. It was also recommended by Coomber & Barriball (2007) to analyze job satisfaction at ward level with qualitative interviews to get a deeper and more extended insight in which specific features are of importance.The aim of this study was to investigate and describe the experiance of job satisfaction in relation to quality of care from nurses perspective. This study was carried out at an orthopaedic ward with primary nursing as organizational context of care.Two focus group interviews were conducted, they comprised nine nurses with at least two years experiance of primary nursing. A qualitative content analysis with inductive approach was used in order to develop more detailed insights of potential factors influencing work satisfaction at ward level.
