In this thesis, the conditions of using the maintenance method live work at the Swedish TSO, Svenska Kraftnät has been analyzed. The study is limited to only include live work on 220 and 400 kV. The live work method is a type of maintenance that can be done, on lines or stations, even though they are still energized. The purpose of this thesis has been to map the present live work situation at these levels in Sweden. The study is based mostly on interviews with people who have specific field competence with in live work but also with personnel at Svenska Kraftnät.

A persistent problem in the construction industry is its low margins of profit. It is often difficult to earn money due to low efficiency and high costs. Logistics on the construction site answers for a large amount of these costs and it is therefore of interest to find new, more efficient logistic solutions. The purpose of this thesis is to compare two different logistic systems and further to evaluate which one that is the most efficient and profitable. A comparison is made between the traditional logistic systems used for years and a new logistic system developed by an industry association called BEAst.

This Master's thesis work was done at SLU, Uppsala, Sweden in cooperation with Upplandsstiftelsen and Uppsala County Council. The studied area is pointed out as an area for EU´s LIFE project, NATURA 2000, concerning the Scarabid beetle Osmoderma eremita. The studied area lies in an agricultural landscape rich on deciduous trees, about 15 km south of Enköping in the County of Uppland. The species is dependent on large, old, hollow trees, which are exposed to sunlight, usually oak trees in this area. I studied the area in detail concerning large old trees (>70cm ø), middle-aged oak trees and young oak trees.

Due to excess precipitation that cause runoff, all soils in Sweden naturally leaches nitrogen.High leaching from arable land is an environmental problem when the runoff reacheswaters. In the international agreement, Baltic Sea Action Plan, the aim is to reduce therunoff of nutrients. Sweden has agreed to reduce its load of e.g. nitrogen to the Baltic Sea.One of the proposed measures is an increased use of site-specific N-fertilization, which hasbeen shown to increase nitrogen use efficiency and therefore also reduce the nitrogen runoff.Either yields are increased with the same total amount of nitrogen, or the total quantityof nitrogen is reduced with preserved yield levels, which is profitable for the farmers.The dynamics of nitrogen leaching differs between top dressing applications above orbelow the economical optimum. There is a consensus about a difference in the dynamics,but not about its magnitude.

Profit in first commercial thinnings of today is hard to achieve. This is because of prevailing pulpwood prices and because of high costs of logging and transport. To reduce these costs higher productivity is advocated. One way to increase the productivity is the use of multi-tree handling harvester heads. The aim of this study was to calculate logging and transport costs in first thinnings, where multi-tree handling has been used.

The craft of planners are planning for a better future. Knowledge about climate change, environment, health and availability effects the trend towards less car dependent societies in favour of public transport and active transport like walking and biking. This study takes place in Västerbotten, one of Sweden?s most north provinces with a population of 260 000 inhabitants. It is a sparsely populated area with two dominant cities, the other municipalities are largely unpopulated.

 This report is an evaluation of Peab's purchase and call-off system, PIA.PIA is used to order goods for Peab's construction sites. The background to the work is that users of the system have understood the system cumbersome to use when purchasing goods for construction sites. The evaluation was carried out by the interviews and tests with users of the program, in this case, supervisors and site managers at the company. Ten users of the system were interviewed and eleven people have carried out a test order.The focus is primarily on the test order that users have implemented, which has been clocked and analyzed for time and cost. The evaluation is also a user analysis concerning how the users perceive the program, mainly in terms of usability, functionality and benefits.The result of this report shows that PIA is economically profitable to use for the purchase of goods for construction sites.

AbstractThe aim of this essay was to examine the process from the teachers plan to what the stundents actually learned in the history subject. Too respond to the aim, I have performed interviews with one teacher, four students and also observed one lesson. The interviews and observations have been analysed according to other writers works in this subject. The questions the essay starts out from is: What is the teachers plan for the lesson? How did the teacher and the students carry trough the lesson? Have the students achieved the teachers aim for the lesson? Thanks to the teachers plan for the lesson, how the teacher carried trough the lesson, and the teachers relation to the students, there was good conditions for learning.

This paper is about employer?s obligation to establish plans for equality between the sexes and the practical use of these plans. The aim is to clarify what national and international law states about plans for equality between the sexes, and to examplify how plans for equality between the sexes is used in practice.For this paper juricprudential metod with a social science perspective is used. Current law has been examined, but this paper also contains an empirical part consisting of interviews with two individuals from a municipality and a private company, and an examination of the two organizations? plans for equality between the sexes.Employers with over 25 workers owe to establish a plan for equality between the sexes.

My purpose in this work was to find out how staff in a middle sized school uses its local Equal treatment plan in its work against bullying. But also to see how the use of a standardized anti-bullying program works to prevent bullying. I have interviewed the principal, teachers, and what we in Sweden call a ?fritidspedagog? and the members of the anti-bullying team to get answers to my questions.  The conclusion of this study is that the school follow and work according to what the Equal treatment plan states, both in terms of prevention, as in working with actual bullying cases. The school has also followed the National School Agency's recommendations on what should be the local Equality plan, but also to follow up and revise it each year. The interview shows that the staff at the school placed great emphasis on talking and discussing with students about how to behave towards each other, they also brought up things that happened at one time and talked about this. The staffs were very committed to work towards the prevention of bullying and the same was true with the school's headmaster.

Syftet med denna uppsats var att redogöra för rättsreglerna som är gällande i den nya plan- och bygglagstiftningen. I den svenska Plan- och bygglagen (1987:10) (PBL) stadgas bestämmelserna om den kommunala mark och vattenanvändningen samt bebyggelsemiljöns utveckling. Allt sedan PBL började gälla har behovet av en mer förenklad och förtydligad plan- och bygglagstiftning succesivt ökat. Detta har motiverats efter ett stort antal utredningsförslag som nu resulterat i en ny Plan ? och bygglag (2010:900) som träder i kraft 2 maj 2011.

The purpose of the work is to highlight schools work to prevent bullying and abusive treatment, find out about schools work to prevent bullying and abusive treatment follow what is written in the governing documents and how schools can work preventively against the same. The questions have been investigated through qualitative interviews and analysis of documents or in the theoretical background. The interviewees and partially schools were selected through an arbitrarily selection. In each plan against abusive treatment states that the monitoring and evaluation should be conducted in a manner that is not consistent with the responses from leisure educator 1, 2 and 3. School B's plan does not contain an overview of the measures needed to prevent and stop abusive treatment of children.

In hydropower plants it is necessary to always have local power supply. Therefore, the plants are equipped with batteries as stationary back up power. Vattenfall Vattenkraft is using lead acid batteries but has been investigating alternatives to replace them. The aim of this study is to investigate the potential of using Li-ion technology as back up power.The study showed that Li-ion batteries have many qualities. The Li-ion technology will decrease the space and maintenance demand.

This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.

The essay discusses how to look at a equality plan of a academic department experiences the, gender equality in general and how power is portrayed from a gender perspective in the academic department. Through the use of qualitative interviews and a short survey the results have shown that few of the staff members have knowledge about the equality plan and few are familiar with its contents. Furthermore results show that the academic department is run hierarchyilly and that both vertical and horizontal gender segregation exists.The climate at the academic department is characterized by the will to work with gender equality but so far there have only been few exercised or planned efforts to do so. The gap between theory and practise is wide, the will to be seen as an equal academic department concerning equality of men and women seems important. The conscious or unconscious strategy of covering up the real gender equality seems to be done by focusing on the numerical equality..
