Abstract Organically managed cereal fields have a higher plant diversity compared to conventionally managed fields. The presence and spatial distribution of plant resources may affect the spatial relationships between prey organisms and their predators and could therefore alter the feeding relationships between predators and pest prey. As invertebrate predators play an important role in biologica

Abstract The pharmaceutical industry is currently facing a high clinical attrition rate. In order to prevent the late-stage clinical failure, many investigations on compound quality and drug-likeness of compounds have been carried out. It has been widely accepted that molecular size and lipophilicity plays an important role in compound quality. Many attempts have been done to find out other fact

The study explores to what extent recent changes (in the last decade) in the medical environment impact physicians’ identities. It has been conducted in Northern Italy (Emilia Romagna Region), interviewing 16 doctors between specialists and general practitioners and linking their insights with the literature. Our aim was to relate the de-professionalization and proletarianization debate to an iden

Abstract Estuaries and salt marshes are important wetlands used by waterbirds during winter and migration. However, many salt-marshes have been transformed into salinas, which currently function as high-tide roosts. Since traditional salt production is no longer profitable, many salinas have been abandoned or converted into aquaculture potentially becoming less attractive to waders. In this study

Popular science summary: Effects of xenobiotics on the harbor seal’s immune system Naturally synthesized toxins and also synthetic substances have both been suspected to cause mass mortality events in marine mammals. Top-predators at the end of the food chain, like harbor seals (Phoca vitulina), accumulate particularly high concentrations of contaminants. Certain substances have been proven to h

Studiens syfte var att undersöka de långsiktiga hälsoeffekterna av en skiftschemaförändring i på ett industriföretag, från ett snabbt framåtroterande schema till ett långsamt bakåtroterande schema. Undersökningen bygger på en studie som gjordes 2004 i samband med denna intervention. Data samlades in med hjälp av formulär som mätte subjektiv hälsa, sömn och trötthet, behov av återhämtning, obalans The purpose of this study was to examine the long term health effects of a shift change from a fast forward-rotating to a slowly backward-rotating schedule in an industrial company. The study is a follow-up of a study that was made in 2004 when this intervention was made. Data was collected using questionnaires covering subjective health, sleep and fatigue, need for recovery, work-family interface

The purpose of this thesis is to examine nanowires made up of compound III-V-semiconductors which can be applied as photovoltaic devices. Two types of experiments are done approaching from two different starting points: Firstly, studies of several III-V-semiconductor wafer surfaces used as a reference for studies of nanowire surfaces and secondly, direct contacting of standing nanowires in order t

Designing efficient artificial retina is one of the prime research focuses for medical engineers. The long term goal of this project is to assess if artificial photoreceptors such as nanowire photodiodes could be suitable for neuronal stimulation. To investigate this, different nanowire substrates (Si NWs, GaP NWs) and nanowire photodiodes (InP NW-photodiodes) were fabricated on substrates in orde

Abstract Sexual selection is considered to be one of the most important processes influencing the evolution and diversification of species. Sexual conflict, a subset of sexual selection theory, describes how opposing interests in the male and female reproductive systems can lead to one sex increasing its fitness at a cost to the other sex. Traits involved in this conflict may come under selection

The main purpose of this thesis is to demonstrate how methods of multivariate statistical analysis could be used to detect possible differences between two groups of subjects for which multivariate observations are collected. In particular, we show that the multivariate methods can be more sensitive at detecting significant differences by contrasting the results with the ones based on univariate s

Författaren till denna studie är sjuksköterska och har arbetat på Skånes Universitetssjukhus. Upplevelserna från denna tid ligger till grund för denna uppsats. Syftet med uppsatsen är att analysera i vilken utsträckning avdelningschefers arbete inom kirurgiska divisionen på Skånes Universitetssjukhus påverkas av ramfaktorer såsom personalfrågor, ekonomi och samhällsaspekter. Metoden som användes

Individuell omvårdnad, information och stöd är en förutsättning för varje patient som får krävande cytostatika- eller strålbehandling. Syftet med denna studie var att belysa hur människan som genomgått cytostatika- eller strålbehandling upplevt stöd och information under behandlingstiden. Den omvårdnadsteoretiska inramningen sker med hjälp av SAUK-modellen, bekräftande omvårdnad. Studien är en int

Executive summary Title: Energy optimization at a chemical industry enterprise Case study - Perstorp AB Authors: Sandra Leksell and Anna Parsdotter Supervisors: Patrick Lauenburg, PhD, Dept. of Energy Sciences, Faculty of Engineering, Lund University and Daniel Hansson, Technical Manager, Perstorp Specialty Chemicals AB Background: The industrial sector in Sweden consumed 152.4 TWh energy in 2010,

The aim of this study was to identify what possibilities three lecturers, called Change Agents, have to implement the concepts from the training programme “Child Rights, Classroom and School Management” at Makerere University. We have analysed how the three factors leadership, organisational structure and organisational culture have affected their space of action in the implementation process. Th

Denna rapport går igenom olika sätt att arbeta med energieffektiviseringsfrågor i olika verksamheter, en enklare energianvändnings kartläggning har även genomförts i kommunhuset i Åstorps kommun

The purpose of this master thesis was to develop a football referee paging flag system. A paging flag system is an appliance to facilitate the assessment of the game and to improve the communication between the referee and the assistant referees. The assistant referees are each equipped with a paging flag and the referee is equipped with a receiver, which vibrates when activated from a button push

Forskning om gester har visat att gester inte bara är ett slumpmässigt bihang till tal, utan också omfattar en rad viktiga funktioner som koordineras med talet. Om och hur gestanvändning påverkas av språkstörning är mindre klarlagt och det finns bara några få studier kring ämnet. Syftet med denna studie är att jämföra gesters funktion i narrativer hos barn med språkstörning respektive barn med typ

Prof. Björn Fritzell publicerade 1996 en studie där han presenterade en kartläggning av röstpatienter på nybesök vid foniatriska mottagningar i Sverige. Insamlingen av uppgifter gjordes efter kön, yrke, ålder och diagnos. Slutsatsen var att yrket kan ses som en riskfaktor för röstproblem, framför allt när det gällde lärare. En uppdatering har sedan dess varit efterfrågad. Föreliggande studie syfta

This thesis deals with the subject of economic optimization of energy production. An initial theoretical part present the various input data required for an optimization. The most basic inputs are the forecasts of district heating load, forecast of electricity price and cost functions. Some different optimization methods used for economic optimization of energy is described. An example of how to
