Populärvetenskaplig sammanfattning: Då man för ner en elektrisk ström i marken kommer vissa material i marken laddas upp p.g.a. att positiva och negativa joner samlar ihop sig på ytor och i trånga porkanaler. Detta kallas för polarisering och kan användas för att bestämma t.ex. vad för typ av geologiska material som finns under markytan eller vart föroreningar i marken tar vägen. Fenomenet som uppIt has been shown that surveys of Induced polarization (IP) often contain data of low quality, because it is highly sensitive against different noise sources. When measuring induced polarization, where the method uses multicore cables and continuous electrode sounding (CVES, Continuous Vertical Electrical Sounding), noise phenomena such as capacitive coupling effects have to be considered. It is p

Stratigrafiska analyser har utförts på en kustklint vid Ålabodarna i västra Skåne, vilken exponerar en skärning genom en liten dödisbassäng. Syftet med undersökningen var bl a att studera vegetationsutvecklingen i ett område som, i förhållande till övriga Skandinavien, tidigt blev isfritt. Fördelen med att arbeta med sediment i en öppen skärning i stället för i en borrkärna är att sedimentens latePopular abstract: A study of sediments from a small ancient lake basin in the cliffs at Ålabodarna, western Skåne, Sweden has revealed important information about the arrival and expansion of vegetation in the area. Western Skåne is a very important area for studies of this type, as the ice streams from the final episode of glaciation during the Late Weichselian retreated from this area early rela

Air sampling and biological sampling have been performed to examine the exposure to nicotine in the Nicorette patch and Nicorette gum production at Pfizer Health AB in Helsingborg, Sweden. For this purpose stationary and personal sampling equipment have been used. At the Nicorette patch production, XAD-2 tubes were used to sample nicotine vapor and at the Nicorette gum production Teflon filters we

The aim of this study was to examine the infiltration rate of water and some parameters affecting it. Especially the land usage, the abundance of roots and macropores were investigated. A field study was carried out on western Java in Indonesia, on the slope of Mount Salak. The study compared four different land uses; i.e. forest, shrub areas, tree plantation and cropland since there was a high o

En slitsmur är en geokonstruktion som utförs genom att paneler platsgjuts med marken som form. Panelerna bildar tillsammans en samverkande vägg. Tekniken är vanlig utomlands men fortfarande relativt ovanlig i Sverige. Behovet, och därmed intresset, av slitsmurar i Sverige växer dock i takt med förtätningen av städer och infrastrukturprojekt som kräver djup schaktning och anläggning. Kraven på låg A diaphragm wall is a retaining wall which is produced as a cast in-situ concrete wall. The ground itself acts as formwork. The technique is widely used internationally but it is comparably still a rare technique in Sweden. However, the need, and therefore interest in Sweden for diaphragm walls is growing as the number of inner city infrastructure projects requiring deep excavations increases. The

As the climate on earth deteriorates, actions are carried out within Europe to limit the amount of hazardous emissions to lower the environmental consequences due to greenhouse gases. A significant proportion of the emissions can be linked to the construction sector and its use of virgin resources. An area with great development potential within the construction sector is linked to its management

Pollen analyses and AMS C-14 measurements were performed on lacustrine sediments and peat deposits from the former crater lake Steregoiu in a mid-altitude area in the Gutaiului Mountains in NW Romania in order to provide a detailed reconstruction of the vegetational development of the area during the Late-Glacial and Holocene. The bottom sediments are siliciclastic and were deposited probably duri

Slam från konventionell avloppsvattenrening innehåller näringsämnen samt mullbildande ämnen vilket medför att materialet utgör en resurs som växtnäring och jordförbättringsmedel. Problematiken med att använda slam är att det även innehåller främmande ämnen som metaller och svårnedbrytbara organiska föreningar. Syvab är ett kommunalt bolag som driver Himmerfjärdsverket men ansvarar också för någrSludge is produced in conventional waste water treatment. The sludge contains nutrients and humic formaing substances which make it useful as a fertilizer. The problem with using sludge is that it also contains toxicants as heavy metals and persistent organic compounds. Syvab is a municipal owned corporation that manage the wastewater treatment plant Him-merfjärdsverket. Since August 2010 Himmer

The immune system is of central importance to clear-off pathogens in order to keep an organism healthy. In vertebrates, the Major Histocompatibility Complex (MHC) is a genomic region that holds key genes involved in adaptive immunity and in particular in the antigen presenting process. The presentation relies on MHC class I (MHC-I) and MHC class II (MHC-II) molecules that are encoded by MHC-I and

Background: Adverse events induced by intravesical bacillus Calmette-Guérin (BCG) to treat high-grade non–muscle-invasive bladder cancer (NMIBC) often lead to treatment discontinuation. The EAU-RF NIMBUS trial found a reduced number of standard-dose BCG instillations to be inferior with the standard regimen. Nonetheless, it remains important to evaluate whether patients in the reduced BCG treatmen

The functional role of striatonigral neurokinins were studied by analysing the effects of intranigral injections of substance P and neurokinin A on the extracellular level of dopamine and dihydroxyphenylacetic acid in the striatum, as measured by in vivo microdialysis in rats. Two substance P antagonists, substance Pd-Pro2d-Trp7,9 and substance Pd-Arg1d-Trp7,9 Leu11 were tested and analysed for th

The breakup of the L-chondrite parent body (LCPB) in the asteroid belt at 466 Ma ago is the largest asteroid breakup documented in Earth's geological record for the past ca. three billion years. Recovery of abundant macroscopic fossil L chondrites in mid-Ordovician marine sediments as well as reconstructions of the flux of micrometeoritic chrome spinel through the ages have given much new informat

Importance: Meningioma is the most common subsequent neoplasm following cranial irradiation among survivors of childhood cancer, but there are still uncertainties regarding the magnitude of the radiation dose-response association, potential modifiers of radiation risks, and the role of chemotherapy. Objective: To evaluate meningioma risk in survivors of childhood cancer following radiotherapy and

Eastern New South Wales (NSW), Australia, is a region prone to frequent and intense droughts. An unprecedented episode of high temperatures and low rainfall in 2017–2019 culminating in the 2019-2020 summer triggered massive canopy dieback of eucalypt forests throughout the region. Subsequent high rainfall in 2020 offered a unique and rare opportunity to study the process of vegetation recovery fol

Introduction Parkinson’s disease (PD) is a common neurodegenerative disease, which has extensive pathology that critically includes the loss of midbrain dopaminergic neurons. This loss leads to debilitating motor features such as bradykinesia and rigidity, as well as some non-motor symptoms. Intracerebral dopamine cell transplants have been explored for many years as a new approach to treating PD

Objective: Our report describes clinical, genetic, and biochemical features of participants with a molecularly confirmed congenital disorder of glycosylation (CDG) enrolled in the Frontiers in Congenital Disorders of Glycosylation (FCDGC) Natural History cohort at year 5 of the study. Methods: We enrolled individuals with a known or suspected CDG into the FCDGC Natural History Study, a multicenter

Uncertainty in our calculations of a system reveals the limits of our knowledge. This limitation makes model representations of the Earth system challenging and our predictions less reliable. However, despite appearing chaotic and non-linear, a system always follows a deterministic trajectory, which can often be expressed probabilistically. Building on this concept, this thesis applies data assimi

Viking Age silver is a useful tool for tracing various aspects of the society. Contact networks, trade organization, society structure, economic variation etc. This paper concentrates on the so-called Permian rings, which appear in Scandinavian silver hoards from Early Viking Age. Their main concentration is, however, in the regions west of the Ural Mountains in Russia. As the rings found in Russi
