The objective of this thesis is to explore opportunities to enhance the phosphorus use efficiencyof inorganic fertilizers in crop production, with techniques available today and in thefuture. Phosphorus is a finite resource of declining quality; therefore a phosphorus use efficiencyin crop production of only 15-30 % is unacceptable. The main reason for low efficiencyis the retention by Ca and Mg in calcareous soils and Fe and Al in non-calcareoussoils. Due to the low mobility of phosphorus, plant uptake is mainly dependent on root growthrather than diffusion. Therefore, measurements need to be taken that benefit contact betweenroot and fertilizer, before fertilizer phosphorus becomes unavailable to the plant.

An increased use of social media has enabled a new arena for HR functions and the work with HR issues. Proponents are critical of this, as it can lead to ethical and legal dilemmas. So far the research on this area is limited. On this basis I found it interesting to study how social media is used in connection with the recruitment process. Those who will benefit from this study are primarily those dealing with recruitment, but also others working with HR issues.

The concept of school forest was drafted in 1970 by the Forest in School organization and is defined as an area occupied by a school for outdoor educational activity. The main purpose of this study was to examine how schools use the school forest in practice, how it can be linked to the forest as an ecosystem service and find out how the forest is taken into consideration in the spatial planning. The study is mainly qualitative in nature and has been based on interviews conducted with educators engaged in outdoor education at four selected schools in a municipality in Sweden. Focus has been on the cultural ecosystem services for school forest, for example the physical characteristics that are considered as positive, forest influence on students' physical / mental health and the educational benefits available to be in the woods. Search has also been made to see how the forest is taken into consideration in the spatial planning and also what a contract agreements involves.

PR appears to be an indistinct division and a complicated resource for companies to value. The current circumstances are negative to the credibility and reliability of PR. This study emphasizes how an application of return on investment contributes to a more strategic use of PR and increases the status and credibility for the division.We experience that measuring the economic value of PR is of great importance and of current interest with few prior studies made. The purpose of this study is to find out how a PR-agency and one of its clients relates to and works with evaluation of PR-activities and to which extent the economic contribution of the activity is measured.The foundation which the theoretical reference grounds on is theories of Delusions of PR and the use of benefit-cost analyzes, Stages and Levels for Evaluating Public Relations Programs, Marketing Return on Investment and PR Return on Investment. The theoretical reference serves as a base during the analyze of the study.The conclusion, based on the empirical body of information, is that an application of return on investment could contribute with a higher status and credibility for the PR-division.

The purpose of this essay is to analytically review and discuss architecturalcompetitions, mainly through the general views of a few selected workinglandscape architects, architects and scientists. I have studied the moral and workethicalaspects of using graphical presentations as a mean to draw attention,rather than trying to meet the set program points.My results are derived from e-mail interviews, literature studies and studies ofthe competition entry Stockholmssfären from the competition Stockholmsportenwhich was held in Sweden early 2011.The literature studies have shown that the available literature on architecturalcompetitions and research on the subject is biased towards architecture ratherthan landscape architecture. Worth mentioning is also that there is not a lot ofavailable literature, mainly due to lacking research on the subject.The informants for the interviews were selected based upon their academicmerits and/or experience of working with or doing scientific research onarchitectural competitions. The landscape architects? opinions regardingarchitectural competitions turned out to be in many ways alike ? they seemed tohave a pretty relaxed view of competing in architecture.

My thesis is based on a qualitative study. The purpose of the study is to investigate whether the educationalist at an especially chosen school in Stockholm promotes the students multicultural background in the education or not.This is due to the fact that the Swedish school to a considerable degree reflects the multicultural Swedish society. The socio-cultural starting point is when people come together and meet. The language is the tool of the socio-culture and it is the dialogue, discussion and sympathetic understanding that makes people meet.The cultural concept is diffuse and very wide. Everyone has their own definition of it.

The aim of this study was to get knowledge of the communicationprocess between the branch head and the co-worker in communal geriatric care. To narrow it down we focused on how the branch head experience the communicationprocess in conflictsituations between co-workers and what she or he usually do to resolve the conflict. We made qualitative interviews with ten of the branch heads in communal geriatric care, in four communes. The questions we had in mind throughout the study was based on four keywords (communication, leadership, conflict and conflict management) of which we created a narrative story from every interviewing person to get hold of the experience and knowledge behind their interviews. In our analysis as theoretical perspectives we used system theory, communication theory, attribution theory and the philosophy of Dialogue by Martin Buber.

During the last Century a tremendously technical advancement has taken place and brought a change in society, which has affected workplaces in a monumental way. Many heavily and moveable physical working tasks at the work placement have been replaced with much easier and sedentary tasks.Two of the major reasons for sick absence in Sweden are illness in the locomotive organs and pain, which can be treated and prevented with physical activity on a large scale. Many employers offer their employees? subsidized exercise cards, which can be used during their free time. A health care exercise hour is one benefit that employers can offer their employees and normally takes place once a week during fully paid working time.

The aim of this thesis is to explore possible differences between public and private companies? way to manage projects. In order to analyze the managerial aspects, we have studied the project of a new payment system implemented at the public-transport organization Upplands Lokaltrafik (UL). The project enables mobile payment by text message (SMS). Most theory concerning the management of projects is developed for private companies.

Internet's entry into our home has changed our communication capabilities. As a result more and more services in the digital world are available. Besides e.g. shopping, gaming and general information, different social networks now offer preventive and therapeutic health-oriented services. When being asked by several young people, with whom I have been working in a clinical setting, to offer conversations over the Internet that enables both to see and to hear each other in real time, I decided to conduct a pilot study which is presented in this paper. The aim was to investigate the feasibility of offering supportive therapy using video calls over the Internet.

Denna uppsats handlar om hur den särskilda tillåtlighetsregeln i 11 kap. 6 § miljöbalken tillämpas vid tillståndsprövning av vattenverksamheter. Av paragrafen följer att en vattenverksamhet endast får bedrivas om den samlade nyttan av verksamheten överväger de kostnader samt skador och olägenheter som verksamheten medför. Syftet med paragrafen är att hindra vattenverksamheter som inte är samhällsekonomiskt motiverade samt utgöra ett extra skydd för miljön utöver miljöbalkens generella miljökrav.Syftet med studien är undersöka hur denna paragraf tillämpas i praktiken ? både i rättspraxis och i ansökningsförfarandet.

In the EU the amount of waste increased by 14 percent during the years 2000 to 2010. EU?s target to reduce waste generation runs parallel with the aim of increasing the efficiency and profitability aligned with energy recovery. In Sweden the energy recovery through incineration is increasing steadily, and 46 percent of the municipal solid waste (MSW) is treated by combustion. This report aims to examine the profitability of processing MSW into Refuse Derived Fuel (RDF) from an economic-, energy- and environmental perspective.

The aim of this Master?s Thesis is to find out whether bibliotherapy, in an unspokenform, is practiced in already existing group formations to be able to determine how practicalbibliotherapy can be seen in a Swedish context and thereby open the possibility for development.To fulfil this purpose I decided to do a case study on a nearby book reading circle for adultchildren of drug addicts. I made three qualitative interviews; two of the mentioned book readingcircle?s leaders and one participant/help leader. I used the following set of questions: What isincluded in the concept Bibliotherapy and how does that relate to practice? How has the bookreading circle examined in this case study proceeded, which methods were used and what kind ofliterature has been used and also what kind of effects did this reading circle have on itsparticipants.

Background: Vacuum assisted closure, VAC, is a method which can benefit wound closure. There are not many reliable studies about the effects of VAC in different types of wounds. Previous studies have shown that patients have experienced pain during dressing changes.Aim: The aim of the study was to survey in what kind of wounds the vascular surgery ward have been using VAC, to study the treatment process of VAC and how it has been documented and also to investigate if patients with VAC experienced pain during dressing changes.Method: The patients were chosen from a ledger, which contained 77 patients that had been treated with VAC on the vascular surgery ward. Data were collected with a journal survey protocol.Results: The result is based on 67 patients with a total of 79 wounds. VAC was shown to have a good effect on wound healing and infected surgical wounds were the most commonly wound category undergoing treatment with VAC.

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.
