The conventional inversion of surface waves depends on modal identification of measured dispersion curves, which can be ambiguous. It is possible to avoid mode-number identification and extraction by inverting the complete phase-velocity spectrum obtained from a multichannel record. We use the fast simulated annealing (FSA) global search algorithm to minimize the difference between the measured ph
The Mo/Cu-dependent CO dehydrogenase from O. carboxidovorans is an enzyme that is able to catalyse CO oxidation to CO2; moreover, it also expresses hydrogenase activity, as it is able to oxidize H2. Here, we have studied the dihydrogen oxidation catalysis by this enzyme using QM/MM calculations. Our results indicate that the equatorial oxo ligand of Mo is the best suited base for catalysis.

Maritime archaeology excavations, even in a more complex environment, have the same objectives and requirements as terrestrial ones: documenting digging operations to analyze data in the best way, interpreting it, and producing new knowledge for the benefit of multiple communities. 3D documentation and management methodologies have spread widely among practitioners; however, 3D comprehensive tools
Handeln med varumärkesförfalskade produkter, som länge har ansetts som en ganska harmlös företeelse som konsumenten varit väl införstådd med, har utvecklats till en väloljad miljardindustri där såväl rättighetsinnehavaren, samhället och konsumenten riskerar att lida skada. De varumärkesförfalskade produkterna består inte längre av dåligt imiterade solglasögon utan av professionellt utformade kopioCounterfeiting has long been considered a rather harmless phenomenon. However, counterfeiting has evolved from a small-scale activity into one on an industrial scale. It has come to pose a serious threat, not only to the interests of the right holder, but to the consumers and the society as a whole. Counterfeit products are no longer just poorly crafted copies of sunglasses; today they are profess
År 2018 ändrades reglerna för förmånsbeskattning av privatfinansierad vård som arbetsgivare betalar åt sina anställda. Tidigare var sådan vårdförmån inte skattepliktig för den anställde och icke avdragsgill för arbetsgivaren, men värdet ska nu tas upp till beskattning i inkomstslaget tjänst och istället är kostnaden avdragsgill för arbetsgivaren. Ett huvudsakligt argument för arbetsgivare att stå In 2018, the rules on taxation of private health care and health care insurances that employers pay to their employees were changed. Previously, such care was not to be taxed for the employee and non-deductible for the employer. The value of such service must now be included for taxation for the employee and is instead deductible for the employer. A major argument for employers to bear these costs
To address global food security challenges caused by population growth and climate change, accurate prediction of crop yield is essential for sustainable agriculture. Winter wheat, a key global crop, faces production instability in regions like Sweden and Morocco due to extreme weather conditions. This study employed unmanned aerial vehicle (UAV)-based multispectral imagery and digital surface mod
Cancer är en otrevlig sjukdom, som drabbar många människor. Man söker ständigt nya och bättre sätt att bota patienter eller åtminstone lindra sjukdomens framfart. Ett vanligt sätt att behandla cancer är med strålning. Strålningen kan bestå av sk fotoner. Fotoner är samma slags partiklar som t.ex. vanligt ljus. Skillnaden är att de fotoner som används vid strålbehandling av cancer har högre energi "Purpose: The aim of this study was to investigate whether inversely planned intensity modulated radiation therapy (IMRT), using the clinical radiotherapy equipment at hand in our department, renders any advantages regarding dose distribution over conventional radiotherapy for head and neck cancer patients in the ARTSCAN (Accelerated RadioTherapy of Squamous cell Carcinoma in the head And Nec
Over the last decade the music festival sector grew enormously: in 2008 over a million festivalgoers gathered in the UK to share music and companionship. However in doing so musicfestivals generate large volumes of waste streams and consume large quantities of resources. Amusic festival of more than 40 000 people will produce in the order of 2000 tons of CO2e –with audience transportation and on s
This thesis presents structural and morphological studies of semiconductor nanostructures, namely quantum dots, nanowires and a dilute ferromagnetic semiconductor. These nanostructures are investigated on the atomic scale using cross-sectional scanning tunneling microscopy (XSTM). Indium arsenide (InAs) quantum dots in both an indium phosphide (InP) and GaAs matrix are studied. The InAs/InP quantu
Developing high-temperature proton exchange membranes (HT-PEMs) that simultaneously achieve high proton conductivity, strong phosphoric acid (PA) retention, and long-term chemical stability remains a major challenge, particularly due to PA-induced plasticization and radical-induced oxidative degradation. Here, we develop a side-chain engineering strategy to decouple PA-binding sites from the polym
Questions: To what extent does the long-term process of grassland succession reflect changes in nutrient availability or other effects of grassland history? Plant communities in ancient, semi-natural pastures include many species associated with nutrient-poor soils. However, semi-natural pasture communities can also develop on previously arable sites — as nutrient levels decline over time. In Euro
Questions Can the model performance of the landscape reconstruction algorithm (LRA) for small forest hollows be validated through comparison to inventory-based vegetation reconstructions from the last 150yrs? Does the application of LRA and the comparison to historical data enhance interpretation of the pollen record? Location Denmark. The Gribskov-Ostrup small forest hollow (56 degrees N, 12 degr
During the course of this three-year project, we have studied aeolian deposits at 70 sites within sixteen areas in south-central Sweden. Inland dunes have been the focus, but some sites with coversand and coastal dunes have also been investigated. We have mapped dune morphology, mainly by LiDAR-based remote sensing, studied the internal sediment architecture by ground-penetrating radar profiling a

Construction in rock is associated with risks because knowledge of the geology and ground conditions is limited. Unforeseen rock conditions involve a large risk to the project and can in the end entail delays and extra costs. To minimize the risks, an optimized pre-investigation program has to be conducted where essential information is gathered in order to make the best decisions throughout the c
The research area of climate field reconstructions has developed strongly during the past 20 years, motivated by the need to understand the complex dynamics of the earth system in a changing climate. Climate field reconstructions aim to build a consistent gridded climate reconstruction of different variables, often from a range of climate proxies, using either statistical tools or a climate model

Popular Abstract in Swedish Den cancerskyddande genen p53 är av betydelse för att göra leukemiceller friska. Blodbildning. Blodceller är nödvändiga för vårt välbefinnande och vår överlevnad. Det finns flera olika typer med egna specialiserade funktioner. Så krävs t. ex. röda blodkroppar för syresättning och vita blodkroppar för att bekämpa infektioner. Blodcellerna har begränsad överlevnad; när Leukemic cells suffer from an impaired ability to differentiate due to inherited or acquired genetic lesions. These genetic changes can sometimes be bypassed with various compounds both in vitro, and, more rarely, in vivo, thus inducing terminal differentiation of the leukemic cells. Differentiation of both leukemic and normal hematopoietic cells is believed to be intimately coupled to cell cycle
Abstract To estimate the timescale of hepatitis B virus (HBV) evolutionary history and analyzing its phylogeographic patterns, publically available HBV sequences were collected from GenBank. Among those, 412 sequences were from genotype A and 566 sequences were from genotype D. These sequences comprised the entire genome and represented samples obtained between 1982 and 2009 from different parts
