The effect of plant species diversity on productivity and competitive ability was studied in an experiment carried out simultaneously in five European countries: Czech Republic (CZ), the Netherlands (NL), Sweden (SE), Spain (SP), and United Kingdom (UK). The aim was to separate the 'chance' or 'sampling effect' (increasing the number of sown species increases the probability that a species able 't
1 Plant species differ in their capacity to influence soil organic matter, soil nutrient availability and the composition of soil microbial communities. Their influences on soil properties result in net positive or negative feedback effects, which influence plant performance and plant community composition. 2 For two grassland systems, one on a sandy soil in the Netherlands and one on a chalk soi
Anställda och uppdragstagare vid universitetet utsätts ständigt för påverkan av andra och utsätter även andra människor för påverkan av olika slag. Sådana kontakter med omvärlden är nödvändiga. För dig som anställd inom en statlig myndighet är det särskilt viktigt att veta vad som kan vara mutor och otillåtna förmåner. Vad är en förmån?En förmån kan se olika ut men har ett värde för mottagaren, so

This thesis addresses the issue of Information Systems (IS) security in pharmaceutical manufacturing which is closely related to the ISA 99 standard. The ISA 99 'Security for industrial Automation and Control Systems' standard is focused on the work for securing process automation systems from IS security threats. The main thought behind the ISA 99 standard is that a high level of IS secur
Purpose: To evaluate and increase the efficiency of the internal processes by clearly visualizing the information flow and present improvement suggestions at Vestas Northern Europe.
Problem definition: To clearly define what information is shared today, identify where the critical interfaces take place and where vital information is lost.
Method: This study takes a her
Proper irrigation scheduling and agricultural water management require a precise estimation of crop water requirement. In practice, reference evapotranspiration (ETo) is firstly estimated, and used further to calculate the evapotranspiration of each crop. In this study, two new coupled models were developed for estimating daily ETo. Two optimization algorithms, the shuffled frog-leaping algorithm
Utgångspunkten är att all vård ska ges på frivillig väg. Genom Lag (1990:52) med särskilda bestämmelser om vård av unga (LVU) har staten en skyldighet att vårda barn och unga vars hälsa eller utveckling riskerar att skadas på grund av missförhållanden i hemmet, trots att behövligt samtycke inte går att få. LVU är en skyddslagstiftning för barn och unga och andemeningen i lagen är att de insatser sVoluntarism is an important starting point upon which all care should be based upon. Through the law (1990:52) with special regulation regarding the care of young people (LVU), the state must care for children and young people whose health or development is at risk of being harmed due to poor conditions in the child's home, even though the necessary consent cannot be obtained. LVU is a protec
Den här uppsatsen handlar om tillämpningen av barnets bästa i vårdnadstvister som föregåtts av umgängessabotage. När vårdnaden om ett barn ska beslutas ska avgörandet göras efter vad som är barnets bästa. Umgängessabotage utgör en omständighet av särskild betydelse i avvägningen mellan olika intressen som alla kan tala för barnets bästa. Därtill är ett barns bästa inte alltid det bästa för ett ann
Uppsatsen behandlar begreppet barnets bästa. Begreppet regleras i föräldrabalken 6:2 a och skall vara avgörande vid alla beslut om vårdnad, boende och umgänge. Syftet med uppsatsen är att försöka klargöra innebörden av begreppet barnets bästa genom en noggrann genomgång av lagtext, förarbeten, doktrin samt avgöranden från Malmö tingsrätt. Som en del i detta undersöks om Malmö tingsrätt låter barne
Proton Beam Therapy (PBT) is an increasingly utilised modality for treating tumours by utilising the physical properties of accelerated proton beams. This review explores the development of PBT, its dosimetric advantages over conventional x-ray-based radiotherapy, and the rationale behind its use in paediatric oncology whilst simultaneously considering the various challenges associated with its de
In recent years, hydrogels have been demonstrated as simple and cheap additives to improve the optical properties and material stability of organometal halide perovskites (OHPs), with most research centered on the use of hydrophilic, petrochemical-derived polymers. Here, we investigate the role of a peptide hydrogel in passivating defect sites and improving the stability of methylammonium lead iod
Oilseed rape fields are a very common crop in the agricultural landscape of southern Sweden, and they can harbour surprisingly many insect species. Some of them are herbivores that feed on various parts of the oilseed rape plant, others are natural enemies of the herbivores, and even more species are tourists from the surrounding landscape. In my thesis I have studied these insects and how their pOilseed rape fields are a very common crop in the agricultural landscape of southern Sweden, and they can harbour surprisingly many insect species.

We have studied the convergence of QM/MM calculations with respect to the size of the QM system. We study a proton transfer between a first-sphere cysteine ligand and a second-sphere histidine group in [Ni,Fe] hydrogenase and use a 446-atom model of the protein, treated purely with QM methods as a reference. We have tested 12 different ways to redistribute charges close to the junctions (to avoid
Popular Abstract in English Proteins are a big biological molecules that help cells to function. Proteins play important roles in all vital processes of the living cell, transporting molecules, speeding up chemical reactions, supporting structure of other proteins and the cell, helping the cell to move. Various disease-causing agents (e.g. bacteria and viruses) are constant threat to us. It is thMost drugs act on biomacromolecules. The Cost of developing new drugs is very high. A method to accurately predict binding affinities would be very useful. We have studied molecular mechanics with generalised Born and surface--area solvation (MM/GBSA) and alchemical free energy perturbation methods (FEP) for use in calculations of ligand binding energies. For the MM/GBSA method we have tested: Ca
Abstract in UndeterminedRelevant source area of pollen (RSAP) and pollen productivity for 11 key taxa characteristic of the pasture woodland landscape of the Jura Mountains, Switzerland, were estimated using pollen assemblages from moss polsters at 20 sites. To obtain robust pollen productivity estimates (PPEs), we used vegetation survey data at a fine spatial-resolution (1 x 1 m(2)) and randomize
