Degradation of organic matter takes place in many processes within a wastewater treatment plant (WWTP). The need for optimisations and extended degradation processes for both organics and nitrogen will increase as outlet demands are strengthened and increasing loads are desired. The purpose of this work was to study the degradation of organic matter at WWTPs within two areas in particular; 1) d

Popular Abstract in Swedish Kärleksdofter och varningsljud i bekämpning av nattfjärilar Jag har studerat hur populationer av skadegörande nattfjärilar kan bekämpas med miljövänliga metoder där djurens egna sinnessystem manipuleras. Liksom många andra insekter kommunicerar nattfjärilar med artspecifika doftsignaler (feromoner) vid parning. Honan avger doften i enstaka nanogram (miljarddels gram!) The impact of olfactory and auditory cues on the mating behaviour in two species of moths, Agrotis segetum (Noctuidae) and Plodia interpunctella (Pyralidae), was investigated to evaluate their potential use in integrated pest management. The flight behaviour of male A. segetum under natural and pheromone-based mating disruption conditions was monitored by harmonic radar. Individual males were equi

Rising temperatures can influence ecosystem processes both directly and indirectly, through effects on plant species and communities. An improved understanding of direct versus indirect effects of warming on ecosystem processes is needed for robust predictions of the impacts of climate change on terrestrial ecosystem carbon (C) dynamics. To explore potential direct and indirect effects of warming

Det ökande byggandet av stadsvägtunnlar, de alpina tunnelolyckorna runt millennieskiftet, och det efterföljande EU-direktiv (2004/54/EC) med minimikrav gällande brandsäkerhet har placerat brandsäkerhet i vägtunnlar högt på dagordningen. Samtidigt är moderna enkelriktade vägtunnlar ofta bland de säkraste delarna av vägsystemet. Har vi kommit till en punkt där resurserna används bättre någon annanstThis thesis can be described as a journey in performance-based fire safety design. Along the way questions such as what fire safety is, how it can be measured, whether we are posing the right questions, or engineer the best solutions, have arisen. The safety journey naturally started out with the traditional view, with fire safety engineering based on limit-based design. Using this paradigm the sa

The thesis concerns experimental studies of bubble motion and the transport of large particles and bubbles. Bubbly flows are encountered in many engineering applications where the bubbles play an important role for the mass transfer between the phases, e.g. in stirred reactors. A special case of bubble transport is the cavitation phenomenon, which mainly has a negative effect on the performance of

The field of wireless communication is growing rapidly, with new requirements for the next generation of mobile and wireless communications technology. In order to achieve the capacities needed for future wireless systems, the design and implementation of advanced communications techniques such as multiantenna systems is required. These systems are realized by computationally complex algorithms, r

Popular Abstract in Swedish Den tilltagande växthuseffekten förväntas innebära en global vattenståndshöjning samt klimatförändringar. En sådan utveckling är ogynnsam för låglänta sandkuster som de runt Falsterbohalvön. I denna avhandling diskuteras framtida höga vattenstånd tilsammans med tänkbara konsekvenser för Falsterbohalvön. Dessutom har kustnära vågor och sandtransport samt grundvattennivåeFalsterbo Peninsula in the south-west corner of Sweden is low-lying and built up of unconsolidated sand. Vulnerability to high water levels and wave action is of concern for the 10,000 residents of the peninsula, especially in consideration of global warming as enhanced inundation and coastal erosion problems may ensue. Rational counteractions of such problems are possible only through sufficient

The cavitation phenomenon has today become a keystone for different areas of science and technology including various industrial processes and medicine. Recently increasing interest and much attention have been paid to study this phenomenon. The last two decades have witnessed the development of numerous devices for different important applications of considerable practical interest, and the rang

This thesis is comprised of five papers that are all related to the subject of financial time series. We study statistical aspects of conditional heteroskedastic models commonly used in modelling financial volatility. Paper I discusses the performance of commonly known information criteria in the presence of various GARCH processes. The investigation has been performed using Monte Carlo simulatio

In this paper we call into question the relationship between development, inequality and territory in the current context of globalization and within the framework of public policies designed, supposedly, to benefit those social actors with fewer resources. In order to do this, we focus on a case study in the northeast of the province of Misiones, Argentina. Here tobacco production, forestry and a

This thesis contributes to research on experimental and behavioral economics as well as auction theory. It consists of five papers.The first paper, Differences Attract: An Experimental Study of Focusing in Economic Choice, studies whether individuals' decisions are affected by focus effects. The focus effect suggests that individuals focus more on an attribute that has a larger difference among th

Zirkon från magmatiska bergarter extraherades från fem granitoider i Birimianterrängen i Ghana., och detritala zirkoner provtogs från sex platser i centrala Västgrönland. Av dessa härrör en population från palaeoproterozoikum i Prøvens magmatiska komplex. De återstående fem detritala populationerna härrör från Arke-iska källor i Västgrönland. Zirkon-populationerna analyserades med LA-ICP-MS-teknikZircon were extracted from five granitoids in the Birimian terrane in Ghana, and detrital zircon were sampled from six locations in Central West Greenland. Of these, one population is derived from the Palaeoprotero-zoic Prøven Igneous Complex. The remaining five populations are derived from the Archean basement in Central West Greenland. Zircon populations were analyzed with the LA-ICP-MS techniqu

The transformational mode of sustainability science is concerned with generating actionable knowledge and practical solutions to complex sustainability challenges in order to facilitate a transition towards sustainability by strategizing transformational pathways. However, some scholars in the field believe that sustainability science lacks such capacity, since so far greater focus has been put on

Denna uppsats utreder vilken roll skiljeförfaranden spelar och kan spela i det privata genomförandet av EU:s konkurrensregler. Det beskrivs och diskuteras hur konkurrensreglernas offentligrättsliga drag påverkar skiljeförfarandet, hur korrekt och enhetlig tillämpning av konkurrensreglerna i skiljeförfaranden kan säkerställas och hur konkurrensmyndigheter kan använda skiljeförfaranden som ett verktThis thesis investigates which role arbitration has and could have in the private enforcement of EU competition law. It is described and discussed how the public law features of competition law affect the arbitration process, how a correct and uniform application of the competition rules can be ensured in arbitration proceedings, and how competition authorities can use arbitration as a tool in the

Semiconductor Nanowires are promising building blocks for advanced optoelectronic devices since their small diameter give rise to quantization effects. The small diameter also makes them susceptible to non-radiative recombination due to surface states. A consequence of non-radiative surface recombination is a reduction of a total recombination lifetime. This is in turn limits an internal quantum e

Title: Adaptation of shipment consolidation and distribution network design to omni-channel retailing Authors: Johan Deniz, Martin Månsson Supervisor: Joakim Kembro, Department of Industrial Management and Logistics, Faculty of Engineering, Lund University Problem description: Global retailers tend to have complex distribution networks. A part of the complexity stems from trade-offs in deciding

Theoretical studies assessing innovation capabilities often tend to be general. This literature might not be completely applicable in practice when it discussing utilities, which are heavily affected by their external environment. Exploring which factors that drive innovation in a utility would therefore cover a gap currently existing in innovation management literature. A theoretical contribution

When referring to the same event, people can have different assumptions. What is interesting to see is why these assumptions are different, why do people have different stories? Some of the reasons could be different levels of expectation, different communication channels or even different cultural backgrounds. We have analysed all these by having a case study within a company that has recently go
