Since the mid-1950s, studies have frequently been conducted on couplings between geometrid moth outbreaks and mountain birch, though not nearly as much focus has been on connections between geometrid moth outbreaks and ground cover. Previous studies have shown that major outbreaks of Epirrita autumnata occur in 9 – 10-year cycles (Karlsson et al., 2004). Sometimes also the Operophtera brumata are
During the second half of August and the first part of September 2017, I radiotracked several European nightjars (Caprimulgus europaeus) around the Stensoffa area in Southern Sweden. Several locations were taken for each bird each night, including diurnal roost and nocturnal points composed by flying and resting behaviours. Being a long-distance migrator already on the way south during autumn migr
Optogenetics is unfolding new ways for us to study the nervous system and could one day be a standard approach to treat neurological diseases like epilepsy. To selectively study the effects on a subcellular level, microscopic light sources are needed. Nanostructure, light-emitting diodes (LEDs) can realize this criteria but processing to connect and protect them is necessary before any fruitful op
Fungi belonging to the genus Trichoderma are filamentous and soilborne, and are usually known for their plant growth-stimulating effects. Trichoderma viride is one of the species belonging to the genus, and is recognized as a plant symbiont known to improve plant growth and pathogen protection. Trichoderma species produce certain antifungal and antibiotic agents called peptaibols, as secondary met
With protectionism on a global rise, non-tariff measures have been an object for public debates and research, as the work of WTO has reduced the possibilities of raising traditional trade restrictions as customs tariffs. Hence governments have turned to non-tariff measures and regulatory standards to fulfill their agendas. This study aims at shedding light on the question of whether non-tariff mea
Mitt arbete utgår från sagan ”Tomtebobarnen” av Elsa Beskow. Jag återupptäckte sagan som vuxen och kände en stark inspiration. Jag brukar inte ha en tydlig inspiration från ett annat medium kopplat till min gestaltning inom arkitektur, så detta var något som jag ville utforska. Inom arkitekturen är skapandeprocessen är en viktig del, därför tycker jag att det är intressant att undersöka den proces
Öresundsregionen är idag Nordens största transnationella samarbetsregion och omfattar hela Skånes län samt östra delen av Danmark. Sedan öppningen av Öresundsbron, år 2000, har regionen varit den arbetsmarknad som vuxit hastigast i Sverige och placerar sig betydligt högre upp än Stockholm på listan. Dock kan man inte se Öresundsregionen som en funktionellt integrerad enhet än. Ett närmare samarbetÖresund Region is, as of today, the biggest transnational region in Scandinavia. The inauguration of the Öresund Bridge in the year 2000 can be seen as the starting point of the regions rapid growth which has led to its surpassing of Stockholm in size. However, it has yet to fully function as an integral unit and a closer relationship between the economies is crucial for reaching a maximum of its
A growing problem in many cities is that the traffic demand fluctuates heavily during the day and that it grows larger as the years go by. This calls for, and the technology to easier measure traffic enables, more efficient traffic light controls that can handle a greater traffic demand but also be adaptive. Centralised control of traffic light might, even though it can be both adaptive and effici
The established scientific reality of asbestos is that (a) asbestos is toxic at a minuscule dose, and (b) exposure should be avoided whenever possible, with the evidence expanding almost exponentially over the past century. The purpose of this research is to explore the historical and global socio-natural entanglements of the economy of asbestos and the resulting mechanisms at play to occlude and
The noise, vibration and harshness (NVH) and body dynamic performance of automotive vehicles is highly dependent of the components included in the body structure and compartment, since they add mass, stiffness and damping to the overall structure. Today, the noise levels in the compartment are predicted using complex and detailed computational models during both early and late stages of the vehicl
Today, the car industry has become one of the greatest users of both wireless and cellular technologies and is increasingly dependent especially in the area of wireless communication. Communication among vehicles is offering a lot of benefits and has testified improvement on safety, efficiency and possible automation of the traffic. A lot of research has been focused on measurement campaigns, by i
This thesis describes the method of identifying unknown parameters that affect the dynamics of a given quadcopter, also known as grey box system identification. This was primarily done utilising an inertial measurement unit and a motion capture camera system. A system of equations describes the dynamics of the quadcopter, and was later coupled with data gathered while flying, in order to use diffe
In this thesis the heating area of a belt furnace for annealing metal powder has been modeled. The model was extended with PI-controllers for controlling the energy added to the model. It was simulated with differently tuned controllers to test tuning principles for finding suitable control parameters for the process. The most promising tuning principles was then written as a manual with the aim f
Resultaten från tidigare miljötekniska markundersökningar utförda av Demikon AB och ÅF Infrastructure AB på fastigheten Berghem 2:26, Ljungby kommun, har visat att fastigheten i fråga är kraftigt förorenad av diesel. Fastigheten återfinns längs med Europaväg 4 (E4), är cirka 2200 kvm och hyser i dag drivmedelförsäljning samt verkstadsbyggnader och lättare industri. Baserat på resultaten från tidig
Freezing injuries usually take place in thawed plant-based food products. To reduce freezing injuries, Pulse Electric Field (PEF) treatment and Vacuum Impregnation (VI) of cryoprotectant were used before the freezing process. The aim of PEF is to provoke electroporation to the membranes of the plant cells, thereby allowing the cryoprotective solution impregnated by VI to penetrate the cells. PEF
Syfte: Syftet med studien var att undersöka om en intensiv läsintervention med det phonicsbaserade datorspelet Grapholearn kunde förbättra avkodningsförmågan hos elever med avkodningssvårigheter. Studien avsåg även se på genomförbarheten och behovet av resurser för att genomföra en intervention med Grapholearn i den svenska skolan. Även möjligheten att använda Grapholearn vid Response to intervent
Syfte. Syftet med föreliggande studie var att undersöka den narrativa förmågan vid återberättande hos 5-åringar med unilateral läpp- käk-gomspalt (LKG) jämfört med jämnåriga utan spalt, samt att undersöka den narrativa bedömningsmatrisen Narrative Scoring Scheme (NSS) som kompletterande analysmetod av återberättartestet Bussagan. Metod. För studien rekryterades 51 barn med LKG och 32 kontrollbarn
Urban fires, particularly in informal settlements in rapidly urbanizing cities in the developing world, are an “everyday disaster” that oftentimes goes unnoticed or under-served in the face of disturbances of the more “lethal reputation”. These disturbances of normal existence are arguably the most debilitating to vulnerable communities and sustainable development, and yet get little attention in
