Nesting phenology in birds has been studied for decades and two different breeding strategies have been identified, income and capital breeding. The nesting behaviour and the breeding strategies of 131 females were studied from three species, the Common eider (Somateria mollissima) (n = 65), known to be a capital breeder and two species the Velvet scoter (Melanitta fusca) (n = 48) and the Red-brea
Utförande av denna Masteruppsats är en del av projektet Ecodiver och i samarbete med vattenavdelningen på Lunds Tekniska Högskola. Syftet med studien är att granska den öppna källkods mjukvaran QSWAT+ som är ett plugin-program i QGIS. Detta för att i kommande tid kunna utveckla ett evidensbaserat verktyg för optimering av våtmarker. Undersökningsområdets omfattning är begränsad till Kävlingeåns avThis Master´s thesis is a part of the Ecodiver project, conducted by the Water department at LTH. The purpose of this study is to review the open-source software QSWAT+ as a plugin in QGIS, to be able to develop an evidence-based tool for optimization of wetlands. The scope of the study area is limited to the catchment area of Kävlinge river; however, no account is taken of the validation of data,
The last part of the product design process is called embodiment design, it aims to give a “physical body” to the product so as to make it ready to use. It is on that particular part of the design activity that I was working, I was included in the research for the embodiment design team of the machine design division in LTH. The main research work was upon the process of this phase, to try to unde
An evaluation of occupant safety in case of a fire has been made for Rosvalla Nyköping Eventcenter as a part of the educational programme of Fire Protection Engineering at Lund University. The condition for occupant safety was that evacuation could be done under safe conditions. A deterministic approach has been applied during the project, which means qualitative and quantitative discussions have
In order to mitigate greenhouse gas emissions effort must be taken on all levels of society. Personal Carbon Trading (PCT) is a policy not yet in use that focuses on emissions from households. PCT policies could in the near future be applied on a national level. If that happens, it is important to know what distributional impacts it could have in order to better predict and moderate unwanted effec
Zambezi River Basin is an international river basin which sustains life of about 30 million people in its riparian countries: Angola, Botswana, Malawi, Mozambique, Namibia, Tanzania, Zambia and Zimbabwe. The main stream of the river enters to Mozambique with average flow of about 2330 m3/s and reaches the outfall in the Indian Ocean with about 4134 m3/s. This makes both the activities in the upstr
It is well established that there is uneven availability of credit across space, in particular for SMEs. The evidence on whether this translates into differences in actual business investments remains scarce. We assess this question by using firm-level data for Swedish firms and estimate the extent to which the average investment-cash flow sensitivities of firms vary across the urban–rural hierarc
Background: Strenuous exercise has been associated with functional and structural cardiac changes due to local and systemic inflammatory responses, reflecting oxidative, metabolic, hormonal, and thermal stress, even in healthy individuals. We aimed to assess changes in myocardial structure and function using cardiovascular magnetic resonance (CMR) imaging in master triathletes early after a full-d
BACKGROUND Anaesthesiology represents a rapidly evolving medical specialty in global healthcare, currently covering advanced peri-operative, pre-hospital and in-hospital critical emergency management (CREM), intensive care medicine (ICM) and pain management. The aim of the European Society of Anaesthesiology and Intensive Care (ESAIC) is to develop and promote a coordinated interdisciplinary and m
Dementia causes substantial suffering for affected persons and their family care-givers. Because no cure is available, it is important to investigate how alternative therapies can improve life for these individuals. For the current study, persons with dementia (PwD) were recruited from a specialized Memory Clinic in Sweden to en-gage in a choral singing intervention for 1 hour per week for four se
Microstructural evolution during the early stages of ageing (less than one hour) in a Ni-Cr-Fe based superalloy Inconel 718 (IN718) has been investigated using Small-Angle X-ray Scattering (SAXS). The effects of precipitate kinetics on the precipitate size distribution are compared indirectly with SAXS measurements by using Vickers microhardness data. The microhardness increased after 4 min of age
The mechanism and kinetics of the radical C-3(2) + C3H8 reaction have been investigated theoretically by direct ab initio kinetics over a wide temperature range. The potential energy surfaces have been constructed at the CCSD(T)/B3//UMP2/B1 levels of theory. The electron transfer was also analyzed by quasi-restricted orbital (QRO) in detail. It was shown that all these channels proceed exclusively
Traditionally the simulation of transient and voltage stability in power systems has been constrained to tools developed specifically for this purpose, e.g. Simpow, PSS/E, ETMSP and Eurostag. While being efficient and thereby able to simulate large systems, their component models are often encapsulated and difficult or impossible to examine and modify. Also, these simulators often require substant
The European Spallation Source (ESS) is a planned neutron source to be built in Lund, Sweden, which is planned to produce the first neutrons in 2019. It will have an average beam power at the target of 5 MW, an average current along the linac of 50 mA, and a pulse repetition rate and length of 20 Hz and 2.86 ms, respectively. The linac will have around 200 LLRF stations employed to control a varie
For most animals their foraging environment consists of a patch network. In random environments there are no spatial autocorrelation at all, while in fine-grained systems positive autocorrelations flip to negative ones and back again against distance. With increasing grain size the turnover rate of spatial autocorrelation slows down. Using a cellular automaton with foragers having limited informat
Measurements of the adiabatic laminar burning velocities of n-heptane, iso-octane, ethanol and their binary and tertiary mixtures are reported. Non-stretched flames were stabilized on a perforated plate burner at 1 atm. The Heat Flux method was used to determine burning velocities under conditions when the net heat loss from the flame to the burner is zero. Initial temperatures of the gas mixtures
In the year 2000, the alcohol habits of 1460 Swedish university students living in residence halls were assessed. The students had a mean age of 23.8 years, and 64% were male. The results from this baseline assessment show that the mean AUDIT score (± sd) was 10.3 ± 5.2 for males and 8.1 ± 4.7 for females. AUDIT stands for Alcohol Use Disorders Identification Test and is used world-wide to assess
Phylogenetic approaches are indispensable in any comparative molecular study involving multiple species. These approaches are in increasing demand as the amount and availability of DNA sequence information continues to increase exponentially, even for organisms that were previously not extensively studied. Without the sound application of phylogenetic concepts and knowledge, one can be misled when
He-3 was a popular material in neutrons detectors until its availability dropped drastically in 2008. The development of techniques based on alternative convertors is now of high priority for neutron research institutes. Thin films of B-10 or (B4C)-B-10 have been used in gas proportional counters to detect neutrons, but until now, only for small or medium sensitive area. We present here the multi-
