Many Swedish amphibians are threatened and included in action plans to prevent them from extinction. There are many reasons for amphibians being threatened but one important factor is the loss of suitable breeding ponds. This report evaluates if 34 ponds created for threatened amphibians, and financed through these action plans, have been colonized by threatened amphibians in Scania. The ponds wer

Syftet med denna kvalitativa studie var att genom semistrukturerade intervjuer synliggöra elever på resursskola och deras upplevelser av problemsituationer och bemötande i en skolmiljö. Åtta elever i åldrarna 10-16 år vid två olika resursskolor i Skåne intervjuades för ändamålet. Tematisk analys användes för identifiering av teman i intervjumaterialet. Resultaten visade att problemsituationer och The aim of this qualitative study was through semi-structured interviewing to make visible students in resource school and their experiences with problem-situations and response in a school environment. Eight students aged 10-16 years at two different resource schools in the south of Sweden were interviewed for the purpose. Thematic analysis was used for identifying themes in the interview materia

Very high accuracy and a very high repeatability, both in the range of a few microns, is very hard to achieve with today's common serial robots. An approach utilizing the Gantry-Tau principle is used in my theses together with a dual motor control to eliminate the troublesome backlash rising from the mechanical limitations. Both hardware and software will be regarded and with an antagonistic c

This master thesis aims to investigate the visual characteristics of Late Bronze Age tholos tombs in the region of Messenia, Greece by comparing tholos tombs from two study areas: the Pylian hinterlands and the Soulima Valley. The study utilises cost surfaces and viewsheds created in a GIS-environment as heuristic devices to do so. With the common assumption that the tholos tombs were erected as v

En analys av den hotbild som BUF avger under mellankrigstiden. Studien baseras på de inrikesministrar som satt under mellankrigstidens senare hälft och halvvägs in i andra världskriget.

Syftet för undersökningen är att utreda identitet, relationer och gränsdragningar i den döva gruppen under 1954-1970. Detta genom att undersöka en lokal dövförening, Malmö Dövas Förening ”Svenske”. Källmaterialet utgörs huvudsakligen av protokollanteckningar från föreningsstyrelsens sammanträden. Analysen stöttade sig mot teoretiska begrepp hämtade ur deaf studies och disability studies, två forsk

Uppsatsen undersöker natursyner i några svenskspråkiga emigrationsskrifter från andra hälften av 1800-talet. Fokus ligger på hur det talas om naturen, naturretoriken, och på relationen mellan natur och människa. Fem huvudteman lyfts fram och analyseras: naturen som resurs, den estetiska naturen, den plan(t)erade naturen, naturen som hälsa och sjukdom samt civilisationens bemästrande av naturen.

High-pressure metamorphism and deformation of the Ullared Deformation Zone (UDZ) in the Eastern segment of the Sveconorwegian Orogen, southwest Sweden is evidenced by ~ 970 Ma retro-eclogite found in association with upper amphibolite and high-pressure granulite facies rocks. Petrographic, structural and geochronological studies of the UDZ were carried out to better understand the regional metamor

This report is a master thesis at Lund University. The aim of the study was to investigate how the formation of a pre-recorded fire evacuation message impacts on the initial evacuation process. Four different messages were tested in 15 unannounced evacuation experiments in cinemas and lecture halls. The occupants in the evacuation experiments filled out a questionnaire about the evacuation and the

It is crucial for the insurance business to create risk profiles for their customers to be able set a fair price for their insurances. This thesis presents an alternative method for measuring the dependence between the numbers of claims made by a customer holding two insurances. The group of insurance holders consisted of 74770 unique customers holding at least two insurances during one year. The

This paper investigates the effect of event-boundaries on false memories. The Deese-Roediger-McDermott (DRM) paradigm was used to test the emergence of false memories in 42 Lund University students and an event- boundary was used to see if this reduced the susceptibility to false recall. The subjects viewed an array of 50 words, one at a time, which each was semantically connected to one of five “

I set out to construct a valuation model for paintings using a newly created sample consisting of paintings sold at Impressionist and Modern art auctions at Sotheby’s between the latter half of 2003 until the end of 2006. I create a valuation model using the standard hedonic regression methods used by other researchers in the art market and describe a new way of viewing the dynamics of the art mar

Översiktliga miljötekniska markundersökningar vid förmodade punktkällor görs genom riktad provtagning, med ett begränsat antal provtagningspunkter som egentligen är för litet för att avgränsa en föroreningsutbredning. Men i de fall resultatet av en översiktlig miljöteknisk markundersökning leder till ett beslut om sanering, krävs det ändå att en bedömning av föroreningsutbredningen görs. I den härSmall-scale environmental soil surveys at assumed point sources are done through targeted sampling at a limited number of sampling locations which makes delineation of a contaminated area difficult. However, if a decision of remediation is taken due to the results of a small-scale environmental soil survey, the size of the contaminated area still has to be assessed. In this study I examined the ac

I en tid som präglas av ekonomiska kriser och besparingar väljer allt flera sjukhus att tillämpa Lean Healtcare, en organisationsfilosofi som utlovar ökad effektivitet och kvalitet. Det är troligt att ändringar som görs när en verksamhet övergår till Lean påverkar flera dimensioner i den psykosociala arbetsmiljön. Studier som undersöker vilken effekt Lean har på anställda är dock sällsynta. Syftet

A machine for magnetizing permanent magnets is under development at LTH. The idea of the machine is to affect only small pieces of a magnet at the time to obtain magnets with an arbitrary flux density, of course with respect to the magnetic material. The final machine is supposed to work in a closed loop fashion. Every part of the magnet is magnetized, measured and magnetized again with a flux den

In this thesis a Direct Current Control (DCC) is implemented for controlling a PMSM. The controller should be implemented in an already existing program. This program is used for testing electrical machines. The new testing method is called Dynamic braking, more information about this method can be read in the report "Performance and efficiency evaluation of FPGA controlled IPMSM under dynami

Large quantities and numbers of organic compounds (OCs) from industries and domestic sources enter the wastewater treatment plants (WWTPs) everyday, which is an ever-increasing issue in modern society. In WWTPs, the pollutants are either degraded or emitted to the air, the effluent (water) or the sludge (biosolids). Even though the sludge may contain toxic contaminants and heavy metals, there is a
