The purpose of this essay is to find out if liming with Ca(OH2) and CaO can reduce leachingof phosphorus from agricultural land and the problem with eutrophication. This purpose alsoincludes getting knowledge about how to make the phosphorus retained in the soil and beaccessible for the plants. This essay is supposed to show if more research is needed in thissubject. There has not been much research about this subject and therefore the amount ofmaterial to study is limited in this literature review. The research reports that have beenstudied have similar results.

The purpose of this study was to examine whether youth novels contained informationconcerning our society. We reviewed youth literature and its history in brief, including itscommencement and development from separate boys' and girls' novels to a common youthnovel after the Second World War.To obtain a clearer picture and a better understanding of youths, we read non-fiction, such asbooks, magazines and articles, concerning youth culture, its meaning and content. We decidedto review the period 1990-1994 more closely. We therefore set up selection criteria whichfinally resulted in 56 youth novels. We examined these novels to determine if and/or how theymatched the nine preselected areas that we felt were typical for the 1990's.

In Scandinavia, capercaillie are often associated with pine trees (Pinus sylvestris) in winter, with pine needles as the main diet. Few dietary studies have been conducted in Sweden and winter diet is subject to little debate. The interesting thing is that this "pine specialist? is also found in spruce (Picea abies) forest habitats where pine is scarce or unavailable. In many studies outside Sweden (primarily Central Europe) spruce is regularly observed in the winter diet, but I have found no reports on the selection of the diet in spruce forest areas in Sweden.

 There is a lack of research in the field of quality improvement efforts based on profound knowledge in social services. The current situation is therefore a significant knowledge gap in terms of studies of this type of systematic quality work and how it is applied in practice. This study therefore intends to describe Pilbackens quality work and further examine if the profound knowledge is consistent with quality work in microsystems by an analysis of Pilbackens work. The present study has been performed by a qualitative method and the material is collected through semi-structured interviews. In order to analyze the study?s result have profound knowledge and the model microsystems been used.

The purpose of this assignment at SSAB Tunnplåt in Borlänge was mainly to investigate and describe the circumstances for the spare parts stored in storage facilities within the area of operation. Even new facilities which could serve as storage rooms and their opportunities for storing spare parts were an important part of the investigation. This because of the need for improved storing of spare parts. Furthermore, market offers where reviewed for storage of spare parts in more tailored designs. The work will culminate in proposals for improvement which is of importance for the development surrounding the storage and handling of spare parts.

This thesis investigates lacks in today?s use of the ERP-system Mapaz Affärssystem inthe production planning at Solna Pressgjuteri, and possible improvements. Today thedates calculated by the program to plan the orders are inaccurate and the ordersequence is not optimal, and therefore continuous manual corrections are needed.The approach was to study the program Mapaz to understand how it works, andidentify available parameters for input and output in the different tools offered in theprogram. By studying old lists of planned orders and relevant parameters in Mapaz forindividual orders, production groups, products and operations, the connectionbetween input and output parameters could be understood.Participating in planning meetings and discussions with the company behind theERP-system identified the current usage, desideratum and possibilities with theavailable tools. These were then matched to describe the reasons to the insufficientplanning and form possible actions for improvement.The work has showed poor understanding for the ERP-system and its functions, assome tools intended to assist the planning were not used, and some even usedincorrectly.

AB Sandvik Cormorant?s production unit in Gimo has identified a need to examinethe handling of products between operations with the purpose of generatingproposals of improvement for the product handling.The aim of this project is to study the existing manufacturing process and givesuggestions for improvement. The proposals should reduce the manual handling ofproducts, decrease the risk of damaging the products during the manufacturing andform a basis for increased traceability. Based on a mapping of the manufacturingprocess and the problem description, a specification of requirements has beencomposed.The mapping of the manufacturing process suggests that a change of the currentsystem is required. The company is recommended to decide how the producthandling between operations should be performed as guidelines for the productionteam.

Nature-like plantations are areas that, by today?s maintenance procedure usually gains low prioritiy and are forgotten. Most nature-like plantations are currently disadvantaged and have in many cases grown up and formed dense,impenetrable and brushwoody green volumes. These green volumes is rarely used, but usually only fills out gap surfaces. With proper care nature-like plantations can become health promoting environments in the increasinglyhardened urban environments.How vegetation systems work and how trees and shrubs interact is dependent on many factors.

This thesis consists of four case studies. The objective is to find out how to get a well functioning cow traffic in an automatic milking system. Different technical and building solutions are analysed and some adjustments are proposed for the DeLaval herd management software. Case study 1: Lactation chart comparison from traditional cow traffic and Feed First? cow traffic Case study 2: Farm A - a study of the precedence passage and the cow traffic Case study 3: Farm B ? an overview of the farm and their way of working Case study 4: Key factors ? how can we judge how well a VMS farm is working? Case study 1: Lactation chart comparison from traditional cow traffic and Feed First? cow traffic In this survey data is analysed from before and after rebuilding to Feed First? cow traffic. Lactation graphs are compared between traditional cow traffic and Feed First? cow traffic.

The employer is obligated to call for negotiation on his own initiative, before he makes decisions in questions, which constitute important changes of the employer?s business or of the worker?s working conditions and terms of employment. The obligation to negotiate is reserved to the organisations, which the employer has collective agreements with. But what does the concept of important changes mean? What areas are included in the concept of important changes, according to legal framework and case law? How extensive is in fact the employer?s obligation to negotiate? The purpose of this report has been to seek answers to the above-mentioned questions, through partly describing how the employer?s obligation to negotiate has developed, and partly describing how the codes of negotiations in the Employment (Co-Determination in the Workplace) Act of 1976 are raised and applied.

The aim of this study was to compare perceived disability in daily activities, anxiety and depression for patients with chronic pain (>3 month), before and after rehabilitation. Another aim was to examine if there were any correlations between disability in daily activities and the extent of anxiety and depression before and after rehabilitation.For the measurements, Disability Rating Index (DRI) that measures disability in daily activities, and Hospital Anxiety and Depression Scale (HADS) ) which measures the extent of anxiety and depression were used. The study was carried out with 50 patients who had suffered from chronic pain and with the objective to return to work after rehabilitation. Of these, 90 % were female. The measurements were carried out at three measure points; before rehabilitation, seven weeks after rehabilitation and one year after rehabilitation.The main result did not show any statistically significant improvement in ability to perform daily activities.The only significant difference that emerged was an improvement in anxiety seven weeks after rehabilitation compared with before.

This thesis deals with local identity and the workplace. We have taken part of stories dealing with local identity and the workplace, by using a qualitative method. We interviewed eleven men working at the same company. The group contained of men from urban areas as well as rural areas. The data from our interviews have been applied to theories of local identity and social theories by sociologists such as Durkheim, Simmel and Tönnies.

The degree project at hand investigates how large areas of older forest (80 plus years) suitable for clear cutting there is on the Swedish island of Gotland. Large areas of older forest on Gotland are situated on land with shallow soil depths which are economically uninteresting and often unsuitable for clear cutting forestry. Other forests hold big nature conservation values and should not, or cannot, be used for forestry purposes. The survey is made as a GIS analysis based on the old but carefully made ?Brief forest inventory? (ÖSI) made in the 1980s and early 1990s. A sample from the inventory is combined with studies of orthophotos, satellite photos and other GIS layers that display estimated soil depth and nature conservation values. Partly contrary to common belief, the survey shows that there are still large areas of older forest suitable for clear cutting forestry on the island.

This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..

This essay analyses the European Food Safety Authority's (EFSA) legitimacy. Theories on input- and output legitimacy are used in the examination. After analysing stakeholder representation, forum for deliberation, transparency, independence, and information sharing, input legitimacy in EFSA is assessed to be high. Output legitimacy was examined through the authority's outcome effectiveness, which was divided into compliance and effectiveness. Since food safety is an immense area, two important parts were chosen for the analysis of output legitimacy; transmissible/bovine spongiform encephalopathy (TSE/BSE) and genetically modified organisms (GMO).
