Strålning kan medföra både skada och nytta. Inom strålbehandling utnyttjas strålningen för att bota eller lindra cancersjukdomar. Målet är att med hjälp av joniserande strålning slå ut alla tumörceller samtidigt som man försöker skona övriga friska celler. Strålningen som produceras i den vanligaste utrustningen för extern strålbehandling, nämligen linjäraccelerator, är elektronstrålning och fotonPurpose: Medical linear accelerators that operate above 10 MeV produce neutrons by photonuclear reactions which present a potential radiation hazard to the personnel. The purpose of this study was to estimate neutron dose contributions to the personnel working with external radiotherapy at Malmö University Hospital (UMAS), compare different kind of neutron detectors/dosimeters, and evaluate how to

The use of biomass as a renewable source of energy has been increasing over the past few decades, and biomass is regarded as a promising replacement for fossil fuels. Thermochemical conversion of biomass is a common approach for biomass utilization with a relatively short conversion time. Despite the many advantages that biomass offers over fossil fuels, the thermochemical conversion of biomass ha

Fuel economy and emissions are the two central parameters in heavy duty engines; most of the existing heavy duty engines are run with diesel. The overall efficiency of diesel engines is good however they suffer from high levels of emissions mainly NOX and soot. Using alternative fuels like Natural-Gas has shown to be a good way to reduce emissions level. Diesel engines can be easily converted to N

Studying how small quantum systems, like molecules and clusters, interact with X-rays is crucial to understanding the ultrafast processes that occur in nature on incredibly short timescales, ranging from femtoseconds to picoseconds. X-rays excite small quantum systems to unstable core hole states, leading to a cascade of phenomena, including Auger decay, nuclear rearrangement, and dissociation. Th

A transcription of the sixth episode of season two.   Rebecca:  This is episode 6 of season 2 or our podcast the Meridian. It's April 8th and when we're recording this, we're located at 55 degrees and 43 minutes north of the equator and 13 degrees and 12 minutes east of the Prime Meridian, so in Lund.    Crossing our local Meridian today. We have a distinguished guest who actually shared a desk wi

This article aims to undertake a comprehensive cost-benefit analysis of SSAB's investment in green steel production under the HYBRIT initiative, focusing on the implications of operating within the EU Emission Trade System and an illustrative scenario employing a carbon tax. The study evaluates profitability and social benefits, utilizing time series models to forecast electricity prices in di

Direct catalytic conversion of methane to methanol offers a pathway for transforming a potent greenhouse gas into a portable clean liquid fuel, thereby mitigating carbon emissions and supporting sustainable energy. However, this process faces challenges from thermodynamically favorable methanol overoxidation. Here, we show that spatiotemporal regulation of photogenerated charge carriers on enginee

The bioeconomy at the watershed scale project is a project initiated by the International Institute of Sustainable Development situated in Manitoba Canada. This project aims to create a bioeconomy using the Common Cattail as the feedstock, while also creating ecosystem services in the watershed through the maintenance of cattail cover. These services include decreasing nutrient loading into Lake W

Automatic brake functions in trucks and cars can save lives but may heat the brakes to dangerous temperature levels. Various types of models for temperature estimation in a disc brake have been evaluated. A homogeneous temperature inside the disc was assumed and this simplification gave adequate modeling results. The implementation was done in Simulink. One model estimated the heat generation base

The last 20 years efforts to find a long-term and large-scale biofuel alternative to petrol and diesel for the transport sector have been intensified with a focus on liquid biofuels, such as ethanol, methanol and Fischer-Tropsh diesel derived from wood. The large-scale production of biomethane has so far largely been overlooked in comparative studies that focus on the long-term renewable options.

Searches for scalar leptoquarks pair-produced in proton–proton collisions at s=13 TeV at the Large Hadron Collider are performed by the ATLAS experiment. A data set corresponding to an integrated luminosity of 36.1 fb- 1 is used. Final states containing two electrons or two muons and two or more jets are studied, as are states with one electron or muon, missing transverse momentum and two or more

The uncoupling proteins (UCPs) leak protons across the inner mitochondrial membrane, thus uncoupling the proton gradient from ATP synthesis. The main known physiological role for this is heat generation by UCP1 in brown adipose tissue. However, UCPs are also believed to be important for protection against reactive oxygen species, fine-tuning of metabolism and have been suggested to be involved in

Load management is a techno-economic measure for harmonizing the relations between supply and demand sides, optimising power generation and transmission and increasing security of supply. It can also benefit the environment by preventing use of generators with higher emissions. This study was performed in collaboration with one electric utility in Southern Sweden, which aims solving peak load pro

Emission formation and flame stability were investigated, both experimentally and computationally, for premixed combustion with varying amounts of water vapor in the mixture. Emission measurements were made in a gas turbine combustor at atmospheric conditions, using Danish Natural Gas (NG) as fuel. The emissions were mapped as a function of humidity, inlet air temperature, equivalence ratio and ae

The recovery of raw materials represents one of the greatest challenges for a circular economy. Especially, the increased demand for lithium in the last years for its critical role in Li-ion batteries implies the need for green technology for Li recovery able to address market requests. Here, we devise and implement a new technology exploiting excitons-based light-to-heat conversion promoted by WS
