Geografiska informationssystem för studier av polyaromatiska kolväten (PAH) : undersökning av djupvariation i BO01-området, Västra hamnen, Malmö, samt utveckling av en matematisk formel för beräkning av PAH-koncentrationer från ett kontinuerligt utsläpp
At the end of August 1999, the local government council of Malmö city decided thatthe area known as Kvarteret Bilen would be made available for the European HousingExhibition 2001 (Bo01-mässan). Kvarteret Bilen extends over approximately 80hectars and includes the western parts of the Western Harbour area (Västra hamnen)of Malmö.Kvarteret Bilen as a whole, but especially the western sections of this area, the socalledBo01 section, has been the subject of heated discussions. This is mainly due tothe fact that the ground in question has proven to be contaminated to a certain extentby different chemical compounds. Investigations undertaken during 1998 showed sporadically high concentrations forespecially one chemical group: polycyclic aromatic hydrocarbons (PAH).The first part of the paper describes the use of a mathematical equation (Fetter 1994)to calculate the concentration of PAH from a continuous discharge at a given time byemploying Geographical Information System (GIS). Even the constraints of theequation are discussed, as well as the consequences that follow as a result of usingGIS.The second part of the paper focuses on the connections between the content ofcarcinogenic PAH in Kvarteret Bilen and the ground water level and type of fillingmaterial.
Urban agriculture : experiences from the Swedish horticulture
Urbanisation has increased the distance between the urban and the rural. Urban agriculture can be a solution to overcome that distance. The characteristic of urban agriculture is the intensive production in intra urban and peri-urban areas. Until 1950s food production in cities was an important part of the urban economy and the urban food supply. Since the 1950s the urban located production of food has almost ceased in Sweden, partly as a result of cheap food imports.
Arkeologihund : En studie i experimentell arkeologi om möjligheten att använda hund som arkeologisk prospekteringsmetod för att lokalisera humanosteologiskt material.
In today?s archaeology there?s a growing need for non-invasive prospection methods. However there?s a methodological gap and what?s missing is a method for locating human bones. In this study a specially trained German shepherd is put through scientific tests determining how good the dog is at telling the different between the scent of human and animal bones.
Aerosolers dygnsvariationer och långväga transporter
This work aims to obtain information on diurnal variations of aerosol concentrations in thecity of Lund (Sweden) and trying to locate the origin of the aerosols long distance transports.The study shows that the aerosol concentrations varied quit strongly over the entiremeasurement period, reflecting air masses of different degrees of pollution, mainly as a resultof the diurnal rhythm of the traffics. Trajectories reveals that air masses originated inSoutheastern and Eastern Europe contains higher aerosol concentrations compared to other airmasses..
Tidsåtgång i mjölkproduktion under betessäsong : inflytande av besättningsstorlek, samt mekaniserings- och automatiseringsgrad
Time studies in dairy production are an essential tool when deciding about level of mechanisation and automatisation both in investment situation and improving efficiency in existing operations. In previous investigations such studies have been carried out during normal barn conditions during winter. Since there is a compulsory to have dairy cows grazing 3 to 5 months during summer time in Sweden time studies during this season is important to have a full picture of needed working time. During grazing season time studies was carried out at 14 dairy farms representing herd sizes from 66 to 450 dairy cows of which 6 farms with AMS. 8 farms were the same as studied during winter season.
En studie av landskapsindex för kvantifiering av rumsliga landskapsmönster
Syftet med uppsatsen är att utvärdera två landskapsindex: ett formindex som beräknar formen för varje markanvändningsyta ( eng. "patch"); ett diversitetsindex, som beskriver de olika markanvändningarnas relativa utbredning. Formindexet beräknas på två olika sätt, beroende på om dess storleksberoende inkluderas eller ej. Utvärderingen körs för ett landskap på cirka 50 km2, men även för tre mindre områden i landskapet: åkerbygd, mellanbygd samt skogs-bygd. Samtliga områden jämförs sedan i två olika skalor, flygbild respektive satellitbild..
En jämförelse av hästens tidsbudget och dygnsrytm : frilevande och i stall
Today it is common to have adult horses stabled for most of the day. This limits the horses? ability to perform some of their natural behaviors such as foraging and movement. The purpose of this review was to compare the feral horses? diurnal rhythm and time budget with stabled horses.
SMED implementation vid slipoperation
The thesis has investigated how Sandvik Coromant could implement the SMED principle on one of their grinders groups and what improvements it would lead to. The aim of the thesis is to identify the current situation and investigate how their setup times would be affected by SMED. The work initiated with a literature analysis about the SMED principles and then proceeded with an analysis of the current situation where the activity was time mapped. The analysis consisted of time trials of the process that the thesis would include. The time studies revealed opportunities for structural improvements to create environment for a more structured process.
A comparison of transporters? paddle use when unloading pigs at slaughter
Today, pigs are moved on farm, between farms, between countries and to abattoirs. This movement of live pigs requires handling practices that are designed for the purpose. The objective of this study was to research the use of paddle in moving pigs, to investigate if there were different methods of paddle practice, explore the time efficiency of different kinds of paddle use and if there were any time variations in methods that varied in intensity of touch. This study was done on two Swedish abattoirs for a total of five weeks. A total of 22 transporters working at two different abattoirs where studied during unloading of pigs at the abattoirs.

Trender i ämnesval hos magisteruppsatser inom kunskapsorganisation 1995-2005 : en innehållsanalys
The aim of this study is to establish whether there are any specific trends in master theses concerning knowledge organization. To identify the past and current trends a method of content analysis has been applied to 110 theses over a time period of ten years. The results of this study show that there is an increasing interest in subjects concerning for example the evaluation of retrieval effectiveness in search engines on the Internet. A subject which was popular in the late 1990:s was information technology and its different applications. This subject has since that time decreased in popularity.
Tid för Time? : En studie i hur musikalisk timing lärs ut
Syftet med studien är att få en fördjupad kunskap om innebörden av Time som begrepp samt att ge en bild av hur erfarna lärare hanterar ämnet i sin undervisning. Denna studie har sin teoretiska utgångspunkt i det sociokulturella perspektivet och hur medierande redskap används i undervisningen.Den kvalitativa forskningsintervjun användes som metod för att få svar på mina frågor. De fem informanterna arbetar i antingen Värmlands eller Örebro Län. De är alla verksamma pedagoger på nivåerna från gymnasium upp till musikhögskola och de undervisar i olika musikämnen. Resultatet visar att ämnet handlar om hur man, som musiker, placerar sina toner i förhållande till en given puls samt att alla informanter understryker att Time är viktigt och bör undervisas i.
Om sjukhusbibliotek i Sverige under 1930-talet ? en litteraturstudie av idéer om biblioteksverksamhet på sjukhus
The study concerns the history and development of hospitallibraries in Sweden in the beginning of the 1900 century.Focus is on the 1930 decade, the time of major expansionof the area. The study is based on study of literature, mainlyfrom articles but also from a few booklets from the time.The purpose of the study is to find out how the librarieswere described in the literature of the time and which goalsand tasks they had. It is also to make it possible to increaseunderstanding of the history of hospital libraries, using it asan inspirational source for development of today´s businessin a time of major change. The result of the study showsthat those goals and ideas are still valid and serve well as aninspirational basis for development of today´s hospitallibraries..
Cykeltidsoptimering av sjuaxligt robotsystem
This master thesis studies how much the cycle time, i.e. the time it takes for an industrial robot to perform a given task, can be reduced if an extra degree of freedom (DOF) is added to the robot system. The extra DOF consists of a linear track, which is supposed to be used in an optimal way. The problem has been studied using simulations in the robot simulation tool RobotStudio. To be able to run an optimization in Matlab, with the RobotStudio simulation cycle time as the object function, communication between Matlab and RobotStudio has been set up with an interface written in Visual Basic.
Konstruktion av mutterdragare för stora moment
This degree project was conducted in collaboration with Gremo AB located in Ätran.The aim of the project was to develop a solution to secure quality and to help assemblingthe locknut holding the vertical hinge on the harvesters and foresters from Gremo.At this time the nut is assembled manually by the aid of an overhead crane. The nut istightened differently from time to time, and there was no specified torque to which it istightened. Another present problem was the locking washer which sometimes getsdamaged during assembly, when this happens the procedure has to be started over fromthe beginning. The current assembly procedure is very time consuming and lengthy forthe employees.Our task was to design a machine that could tighten the nut to a specified torque with amargin of error of ± 3%. The assembly procedure will be held simple and the timerequired at a minimum.The project started by developing several principle solutions, the one solution that bestmatched our specifications were developed to a primary solution.Today we have started manufacturing and assembling our prototype.
