The forest industry has big problems with the bark beetle attacking trees. This results in that they must log the damaged trees, which leads to an economic loss. For a tree to be able to stand against a big populations of bark beetles, it needs to have a strong defence or be surrounded by other trees via associational resistance. Furthermore, natural enemies to the bark beetle can also act as a de
Den 1 januari 2016 skärptes kraven för luftutsläpp från förbränningsanläggningar genom För-ordningen (2013:252) om stora förbränningsanläggningar. I förordningen skärptes bland annat kraven för utsläpp av kväveoxider, NOX. Till följd av de skärpta kraven berördes Kraftringens produktionsanläggning Gunnesboverket. På anläggningen finns tre biooljeeldade hetvatten-pannor för fjärrvärmeproduktion därNew regulations regarding emissions of air pollutants came into force as of January 1st 2016 in Sweden. The regulations are found in “The Regulation on Large Combustion Plants” SFS 2013:252. The regulation contained stricter regulations of NOX emissions which affected the energy company Kraftringen and their three biooil-fueled boilers, at the heating plant Gunnesboverket, that are used for produc
Problem Statement: Company Pie is planning for a new centralised distribution centre, as part of a reorganisation of their distribution network. This entails consolidating volumes from several existing facilities, and another company named Company Rho, when setting up a distribution centre configuration. Company Pie wants a second set of eyes to create a configuration, including operations, and de
I takt med en ökande befolkningsmängd och den pågående digitaliseringsprocessen, finns det ett behov av en effektiv planeringsprocess. I Sverige finns det både nationella och internationella mål som berör detta. Detaljplaner är ett viktigt verktyg för att reglera planeringsprocessen. Vid nybyggnationer och förtätningar av städer krävs det att analyser utförs för att säkerställa att krav på buller,In line with an increasing population and the ongoing digitization process, there is a need for an effective planning process. In Sweden, there are both national and international goals that concern this. Zoning plans are an important tool for regulating the planning process. In the case of new constructions and densification of cities, it is required that analyzes are carried out to ensure that r
The spread of artificial light on Earth increases annually. One of many causes of this spread is due to increased street lighting and artificial light at night (ALAN). Lighting is one of the many necessities for people to feel safe. On the other hand, ALAN, which contributes to light pollution, negatively affects biological functions and thus biodiversity. The purpose of this study was to investig
Syftet med denna studie är att ge klarhet i adoptionsprocessen av en plattformsbaserad affärsstrategi för ett etablerat företag genom en fallstudie i den diskreta tillverkningsindustrin. Studien avser att bidra till den nuvarande begränsade litteraturen om affärsstrategiska och organisatoriska följder för etablerade företag när dessa implementerar en plattformsbaserad affärsstrategi. Därav är fors
The purpose of this research is to investigate existing perceptions upon the sanctions relief amongst middle class Iranian youths between the ages of 25 to 30, living in Karaj and Tehran. The thesis also examines how the economic sanctions have affected their private economies in the post-sanctions era to fill the research gap within the development research field. Semi-structured interviews were
Problem: Dagens samhälle genomgår en ständig förändring och denna har beskrivits som en intensifiering av medialiseringen. I kärnan av denna utveckling återfinns medielandskapet och detta har beskrivits i termer av globalisering vilket i sin tur är nära sammanbundet med en ökad frikoppling från tid och rum. Den intensifierade medialiseringen och medielandskapets globalisering verkar genom en ökad
Den 16 april 2026 presenterades det nya lagförslaget gällande skärpta regler för unga lagöverträdare i proposition 2025/26:246. I propositionen föreslås bland annat en partiell sänkning av straffbarhetsåldern till 13 år vid allvarlig brottslighet samt införande av ungdomsfängelse för åldersgruppen 13–14 år. Syftet med denna uppsats är att granska argumenten bakom förslaget och hur det förhåller On April 16th, 2026, the new legislative Government bill 2025/25:246 regarding stricter rules for young offenders was presented. The bill proposes a partial lowering of the age of criminal responsibility to 13 for severe crimes, and the introduction of youth imprisonment for the 13–14 age group. The purpose of this thesis is to examine the arguments behind the proposal and compare them with prev
OBJECTIVE: Currently available hand prostheses lack sensory feedback. A "phantom hand map", a referred sensation, on the skin of the residual arm is a possible target to provide amputees with non-invasive somatotopically matched sensory feedback. How-ever, not all amputees experience a phantom hand map. The aim of this study was to explore whether touch on predefined areas on the forearm can be as
Background: The kidney injury molecule-1 (KIM-1) has previously been associated with kidney function in rodents and humans. Yet its role as a predictive marker for future decline in kidney function has remained less clear.Methods: At baseline (1991-1994), fasting plasma KIM-1 (p-KIM-1) was measured in 4739 participants of the population-based Malmö Diet and Cancer Study. Creatinine and cystatin C
Metal-halide perovskites (MHPs) are promising as active optoelectronic materials for a diverse range of devices. Anion exchange is a post-growth modification of MHP materials that allows tuning of the band gap and crystal structure by exposure to alternative halides, normally using solution methods. Here, low temperature gas-phase anion exchange for the conversion of CsPbBr3 nanowires (NW) into Cs
Steady state and ultrafast spectroscopy on [FeIII(phtmeimb)2]PF6 (phtmeimb = phenyl(tris(3-methylimidazol-2-ylidene))borate) was performed over a broad range of temperatures. The intramolecular deactivation dynamics of the luminescent doublet ligand-to-metal charge-transfer (2LMCT) state was established based on Arrhenius analysis, indicating the direct deactivation of the 2LMCT state to the doubl
BACKGROUND: Most cerebral palsy (CP) cases have an unexplained etiology, but a role for environmental exposures has been suggested. One purported environmental risk factor is exposure to endocrine-disrupting pollutants specifically per- and polyfluoroalkyl substances (PFAS).OBJECTIVES: We investigated the association between prenatal PFAS exposures and CP in Swedish children.METHODS: In this case-
The WORLD6 model is a fully integrated dynamic world systems model. It includes a biophysical global economic model, based on first principles of physics and thermodynamics, forcing it to be fully consistent with the underlying mass- and energy balances. The WORLD6 model first creates value from extraction of natural resources, input of human labour, the efficiency effect of mechanization and auto
White noise has been proposed to enhance cognitive performance in children with ADHD, but findings are inconsistent, and benefits vary across tasks and individuals. Such variability suggests that diagnostic comparisons may overlook meaningful developmental differences. This exploratory study examined whether developmental characteristics and subjective evaluations of auditory and visual white nois
