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

The Water hyacinth is one of the worst aquatic weeds in the world and it is today present on all continents except Antarctica. It causes big problems for both people and the aquatic ecosystems in many countries. A lot of research has been completed to find methods to eradicate the weed and a lot of money has been spent on management to keep waters clean. In this literature study on management meth

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

Abstract in Undetermined Astra- och Microsoft-fallen väntar på avgöranden i Förstainstansrätten. Bägge väcker viktiga principfrågor i skärningspunkten mellan immaterialrätt och konkurrensrätt. Astra1 har fällts av kommissionen för att företaget missbrukat sin dominerande ställning. Med tveksamma och delvis felaktiga uppgifter har Astras ”blockbuster” Losec fått ett förlängt patentskydd. Trots ins

Popular Abstract in Swedish Lymfom är en grupp tumörsjukdomar som uppkommer från de vita blodkropparna i vårt immunförsvar. Diffust storcelligt B-cellslymfom (DLBCL) är en av de mest aggressiva varianterna av lymfom och uppkommer från den typen av vita blodkroppar som kallas B-celler. Varje år drabbas ca 500 personer i Sverige av DLBCL. Typiska symtom är hastigt tillväxande lymfkörtlar samt viktneDiffuse large B-cell lymphoma (DLBCL) is an aggressive and heterogeneous disease. Identification of prognostic and predictive markers is important to design individualised and effective treatment strategies. This thesis describes different approaches to search for molecular prognostic markers and an attempt to overcome chemotherapy resistance in DLBCL. In the first study it was investigated whet

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

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

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.

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.

A recombinant Baeyer-Villiger monooxygenase, BVMO4 from Dietzia sp. D5 has been previously reported. The enzyme exhibited good thermostability and was active with a wide range of cyclic ketone substrates but catalysed poorly the conversion of cyclohexanone to caprolactone. The present work focuses on protein engineering of BVMO4 to improve the conversion of cyclohexanone. Thus, a structural model

An archaeological excavation made within contract archaeology almost invariably means that the site is destroyed. This means that the documentation, which can be seen as the site’s remaining archive, is extremely important. In this master’s thesis the written digital documentation from eight excavations made within Swedish contract archaeology between 2000 and 2013 is examined using the technique

Summer greetings from the Director Time flies. It seems like yesterday when nature was painted in shades of brown and grey and we were gradually recovering from the pandemic. Now nature shows its best face – lush and an amazing display of color. At the same time, it feels that we have taken a step back since most of us are affected by yet another new lock-down, but for a very different reason. The

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

The aim was to produce a thermostable enzyme that could be used to remove sugar residues from glucosylated natural products classified as flavonoids by applying a method combining extraction in hot pressurized water with enzymatic hydrolysis.

Decomposition of soil organic matter (SOM) in permafrost terrain and the production of greenhouse gases is a key factor for understanding climate change-carbon feedbacks. Previous studies have shown that SOM decomposition is mostly controlled by soil temperature, soil moisture, and carbon-nitrogen ratio (C:N). However, focus has generally been on site-specific processes and little is known about v

The carbon cycle of the terrestrial biosphere plays a vital role in controlling the global carbon balance and, consequently, climate change. Reliably modeled CO2 fluxes between the terrestrial biosphere and the atmosphere are necessary in projections of policy strategies aiming at constraining carbon emissions and of future climate change. In this study, SMOS (Soil Moisture and Ocean Salinity) L3

Popular Abstract in Swedish Den här avhandlingen har behandlingsresultaten av permanent djupelektrod stimulering i hjärnan (Deep Brain Stimulation, DBS) undersökts ur såväl symptomminsknings som patients och närståendes perspektiv. DBS behandling innebär att en elektrod med fyra poler opereras in i hjärnan genom ett litet hål i skallbenet, och den kopplas till pulsgivardosa. Hela systemet är doltThe treatment related effects and personalized goal fulfilment of Deep Brain Stimulation (DBS) have been assessed in studies with different designs. The brain targets included the thalamus for medically intractable tremor in Parkinson's disease (PD) or essential tremor (ET) and the subthalamicus for reducing hypo-, bradykinesia, tremor, rigidity and dystonia in PD.
