Two acid deposition scenarios were simulated for six European forest sites situated in Germany, Denmark, Russia, Switzerland, Spain and Ireland. Three models were used in combination; the RAINS (Regional Acidification INformations and Simulation) model, the SAFE (Simulating Acidification in Forest Ecosystems) model and the MakeDep model. The scenarios used were based on results from international
Abstract Background. Traditional crash-based analysis of road safety at individual sites has its shortcomings due to low numbers and the random nature of crashes at individual sites and the related statistical issues, as well as the under-reporting of crashes and lack of information on contributing factors and the process preceding crashes. To get around the problem, road safety analysis based on
This paper presents a millimeter-wave (mm-wave) phase-locked loop (PLL), with an output frequency centered at 54.65 GHz. It demonstrates a mode-switching architecture that considerably improves the lock time, by seamlessly switching between a low-noise mode and a fast-locking mode that is only used during settling. The improvement is used to counteract the increased lock-time caused by cycle-slipsThis paper presents a millimeter-wave (mm-wave) phase-locked loop (PLL), with an output frequency centered at 54.65 GHz.

Adsorption to microcrystalline cellulose (Avicel) of pure cellobiohydrolase I and II (CBH I and CBH II) from Trichoderma reesei has been studied. Adsorption isotherms of the enzymes were measured at 4 degrees C using CBH I and CBH II alone and in reconstituted equimolar mixtures. Several models (Langmuir, Freundlich, Temkin, Jovanovic) were tested to describe the experimental adsorption isotherms.
A mobile stroke unit (MSU) is an advanced ambulance equipped with specialized technology and trained healthcare personnel to provide on-site diagnosis and treatment for stroke patients. Providing efficient access to healthcare (in a viable way) requires optimizing the placement of MSUs. In this study, we propose a time-efficient method based on a genetic algorithm (GA) to find the most suitable am
Communication is a keyword to success in a construction project and whit modern-days situation with the reduced building time and a lot of stress involved is it very important that correct information reaches out to the right persons on the right time. Many different partners are involved in the building project and each one of them works towards their own goals without thinking of the integrity.
Today it is no news that there exists social exclusion and vulnerable groups of people in our cities and all around our country. This is often connected to preconceptions about certain areas. I can see in the face of us people hope of future, dreams and goals. But when and how are we given the opportunity to, irrespective of our knowledge or background, together affect and influence our surroundin
Infrared (IR) spectroscopy has many advantages over optical, one of which is allowing us to see through intergalactic dust, letting us probe deeper into space and dust-dense regions such as galactic centers. However the investigating the IR spectral range is a relatively new field, owing to recent developments in detector technology, and stellar parameter determination in IR is not well researchedMillions of stars litter the night sky, and our understanding of how they were born is still developing. These burning orbs of gas are so far away that even the light they give off takes years to arrive to us on Earth. So how are we to measure anything about them if sending any equipment to their distant locations is unimaginable? Since the days of Newton, the only way we have been able to say any
Ett stort varmt tack till alla er som deltagit och bidragit till konferensen BEYOND SITE/SIGHT och till Helsingborg stad och Region Skåne för samarbetet under konferensen.

Treatment of met-myoglobin (Fe-III) with H2O2 gives rise to ferryl myoglobin, which is closely related to compound II in peroxidases. Experimental studies have given conflicting results for this species. In particular, crystallographic and extended x-ray absorption fine-structure data have shown either a short (similar to170 pm) or a longer (similar to190 pm) Fe-O bond, indicating either a double
Global solar radiation (GSR) prediction capability with a reliable model and high accuracy is crucial for comprehending hydrological and meteorological systems. It is vital for the production of renewable and clean energy. This research aims to evaluate the performance of combined variational mode decomposition (VMD) with a multi-functional recurrent fuzzy neural network (MFRFNN) and quantile regr
Varje år sker det tusentals olyckor i trafiken i Sverige till följd av det stora transportbehovet i samhället. Transportstyrelsen har ett mål, Nollvisionen, som innebär att ingen ska dödas eller skadas allvarligt i trafiken. För att nå målet är en åtgärd att hastigheten sänks där gång- och cykeltrafik behöver interagera med motorfordon. Det kan man göra i form av sidoförskjutningar, avsmalning av Every year, thousands of traffic accidents occur in Sweden as a result of the transportation need in society. The Swedish Transport Agency has a goal, Vision Zero, which means that no one should die or be severely injured in traffic. To reach the goal one measure is to reduce the speed where pedestrians and cyclists need to interact with motor vehicles. This can be done by chicanes, narrowing of t

This paper evaluates the arsenic adsorption characteristics of a macroporous polymer coated with coprecipitated iron-aluminium hydroxides (MHCMP). The MHCMP adsorbent-composite fits best with a pseudo-second order model for As(III) and a pseudo-first order kinetic model for As(V). The MHCMP shows a maximum adsorption capacity of 82.3 and 49.6mgAs/g adsorbent for As(III) and As(V) ions respectively
Signal is a very important part of the railway. If you place a signal or a different object which is also important in the wrong place, can mean increased safety risks. To ease the work of the consultants in the creation of operational site drawings, the aim is to develop an action plan for the creation of a database, which in turn will be used to create a tool that can be used to automate the pro
Electrification of energy demand is seen as one of the key elements of energy transition toward decarbonisation. E-mobility is one main side of the electrification process, and it is considered as a crucial way to reduce the emissions of the transport sector. A core element for a widespread adoption of electric vehicles (EVs) is the deployment of the charging infrastructure, and installing a micro
