Försurning och övergödning utgör betydande hot mot världens ytvatten och svenska vatten är bland de mest utsatta. I den här studien har avrinningsområdet Storskogen analyserats för att undersöka sambandet mellan atmosfäriskt nedfall, hydrologi och ytvattenkemi. Med atmosfäriskt nedfall menas de luftburna föroreningar som landar på avrinningsområdet antingen för att de fångas upp av trädkronorna eWater chemistry alterations such as acidification and eutrophication represent major threats to the running waters of the world, and Swedish waters are among the most vulnerable. In this study the small forested catchment Storskogen, part of the SWETHRO monitoring network, was analysed to examine the links between deposition, catchment hydrological properties and surface water chemistry.

Järn är essentiellt för livet som vi känner det idag. Det är en del i flera av de huvudsakliga energisystemen som finns i de flesta levande organismer. Men järn som är fritt i en cell kan orsaka enorma skador genom att det deltar i en process som bildar så kallade syreradikaler. Det finns därför en mängd olika proteiner som på olika sätt binder och reglerar järn. Fel med dessa proteiner kan leda tFriedriech's ataxia is a serious neurological condition that is caused by a deficiency in the expression of the protein frataxin. This deficiency is caused by an extension of GAA repeats in the first intron of the frataxin-coding gene. The disease can have an onset as early as five years and by the time the patient has reached 20 years they often require a wheelchair and help to be able to hav

With the climate change and urbanization process, the frequency of the urban flooding’s occurrence has increased in the recent years. It brings great economic losses to the cities, especially to the basements of individual properties. Low Impact Development (LID), which currently advocated by more city planners for managing stormwater, is considered as a more sustainable way to mitigate urban floo

The genus Caldicellulosiruptor and especially Caldicellulosiruptor saccharolyticus are gaining attention because of their potential as biohydrogen producers from agricultural and forestry waste on an industrial scale. Genetic and in turn metabolic engineering can be used to aid in the characterization of C. saccharolyticus. Additionally, it can be used in strain improvement to overcome limiting fa

INTRODUCTION: Esophageal squamous cell carcinoma (ESCC) carries a poor prognosis, but earlier tumor detection would improve survival. We aimed to develop and externally validate a risk prediction model based on exposure to readily available risk factors to identify high-risk individuals of ESCC.METHODS: Competing risk regression modeling was used to develop a risk prediction model. Individuals' ab

The effects of high hydrostatic pressure (up to 8 kbar) on bacteriochlorophyll a Qy electronic absorption bands of LH2 photosynthetic antenna complexes have been studied at ambient temperature. A variety of samples were studied, including intact membranes and isolated complexes from wild type and mutant photosynthetic bacteria Rhodobacter sphaeroides, Rhodopseudomonas acidophila, and Rhodospirillu

Populärvetenskaplig sammanfattning: Vinderosion på jordbruksmark har länge varit ett välkänt faktum trots att någon utförligare undersökning om dess omfattning och skadeverkan inte tidigare genomförts. Mot bakgrund av detta har därför ett nordeuropeiskt projekt, WEELS (Wind Erosion on European Light Soils), dragits i gång som syftar till kartlägga vinderosionen på sandig jordbruksmark i norra Euro

Tre borrkärnor bestående av sjösediment, vardera 1.5 meter långa, från Byestadsjön i Småland, Sverige studerades med hjälp av mineralmagnetiska- kol- pollen- och röntgenflourosens (XRF)- analyser. Målet med studien var att rekonstruera tidig Holocen miljö, med fokus på tiden mellan 9000-7000 år sedan och därmed avgöra om det kalla klimatåterslaget cirka 8200 före nutid påverkade regionen eller ej.Three sediment cores, each 1.5 meters in length, obtained from Lake Byestadsjön in the province of Småland, southern Sweden were studied with high resolution mineral magnetic measurements, carbon content, pollen analysis and XRF analysis. The aim was to reconstruct the early Holocene environment, with focus on the period between 9000-7000 cal yr BP, and thereby conclude if the 8200 cal yr BP cooli

“Comparing Apples & Oranges – A Life Cycle Perspective on the Energy Requirements in Swedish and British Columbian Building Codes” The requirements to decrease the energy use in a building vary in the building codes. “British Columbia Building Code” (BCBC) prescribes a nominal thermal resistance of insulation, while “Boverket’s Building Regulations” (BBR) requires an annual specific energy use

With the increasing Internet usage and the increase of W-commerce in Sweden, online marketing has become an essential and crucial activity for most industries and companies. Online marketing has developed rapidly and there are today a big number of digital channels and tools to add into the marketing strategy in order to meet the changing consumer behaviour. Today we are starting to see a number o

A personal transporter is under development at LTH, Industrial Electrical Engineering and Automation, IEA. A wireless link is desired to develop control remotely for the transporter. The development of the control becomes easier without wires and if the transporter can move freely within the range of the link. A link is built, using Bluetooth devices and a microprocessor from Microchip. This link

Due to the climate crisis we are facing, we can no longer consider current construction methods, which contribute to 40% of global CO₂ emissions, as an alternative to building. Vernacular architecture, in comparison, offers a sustainable alternative. People have experimented with this approach to designing, constructing, and living throughout time. This system essentially stands for maximizing eff

Foton för forskning och framtiden Kan lösningen på ett forskningsproblem vara din smartphone? Om vi frågar grundarna till projektet CoastSnap är svaret ja! CoastSnap är ett så kallat medborgarforskningsprojekt, vilket innebär att allmänheten deltar i forskning genom att hjälpa till med datainsamling. Kusten är ett utmanande forskningsområde, och i och med klimatförändringarna och den stigande havThe coast is an ever-changing environment, and due to climate change, coastal research is becoming more challenging. To detect changes in the coastline, such as erosion, researchers need large amounts of data over long periods of time. Part of the solution could be the citizen science project CoastSnap – a global community beach monitoring program. The aim of this study was to examine factors that

De flesta associerar förmodligen ordet katalysator med bilkatalysatorer där smutsiga avgaser från fordon renas genom att gasen får reagera med syre och därmed bilda mindre skadliga produkter. Så kallade heterogena katalysatorer är ofta metalloxider och de används i många industrier för att möjliggöra kemiska reaktioner. Ett sådant exempel är Formox-processen, där en katalysator bestående av järnmoIn the Formox-process, methanol is converted to formaldehyde via partial oxidation on a heterogeneous iron-molybdate catalyst. To an extent, the formed formaldehyde (FA) is over-oxidized into carbon monoxide (CO) which cannot be recycled into FA. As CO affects the environment negatively and decreases the process economy, internal attempts have previously been made to decrease the CO formation of t

Cities today globally face significant problems in the context of the climate crisis. Firstly, in terms of resilience in enduring future challenges – urban heat islands, increasingly frequent flooding, supply chain disruptions, sea level rise among others. Secondly, in terms of contributing to said crisis, through carbon emissions, the erosion of biodiversity through sprawl, overconsumption, and c

Låneförbuden i den svenska aktiebolagslagen (ABL) utgör kapitalskydds-regler och innefattar två separata förbudsbestämmelser. Först, ett generellt låneförbud, ofta benämnt som förbudet mot närståendelån, som specificeras i 21 kap. 1§ ABL. Detta förbud hindrar aktiebolag från att låna ut pengar till exempelvis styrelsemedlemmar, aktieägare i bolaget, eller andra bolag inom samma koncern. För det anThe loan prohibitions in the Swedish Aktiebolagslagen (ABL) constitute capital protection rules and mainly encompass two separate prohibition provisions. First, a general loan prohibition, often referred to as the prohibi-tion against loans to related parties (närståendelåneförbudet), which is specified in ABL chapter 21, section 1. This prohibition prevents Swedish limited companies (Sw. aktiebol

Både Sveriges rättsväsende och makthavare gjorde avsteg från gällande processrätt på 1600-talet. Den samtida lagstiftningen uppställde stränga regler för rättegången, bevisvärderingen och straffen. Trolldom hade utgjort ett brott enligt lagstiftningen sedan medeltiden. Med förändringar inom rättsväsendet utökades brottet, samtidigt som anklagelser om Blåkullafärder och djävulspakter spred sig övBoth the Swedish Judiciary and rulers made deviations from applicable procedural law in the 17th century. The contemporary legislation set up strict rules for the trial, the evaluation of evidence, and the punishment. Sorcery had constituted a criminal offense according to the law since the Middle Ages. With changes within the Judiciary, the crime was expanded, while accusations of journeys to Bl

For those who experience development-induced displacement and involuntary resettlement, they have to confront a range of adverse consequences, including the impoverishment risks, lifestyle and livelihood changes, and the precarity brought by asymmetrical power relations. Based on a case study of the Three Gorges Project (TGP), this research investigates the role of state law in shaping the identit

Drainage of peatlands causes changes in water table (WT), vegetation and decomposer community. As a consequence, decomposition patterns and carbon dynamics change, which is visible in altered Dissolved Organic Carbon (DOC) concentrations in ground and soil water. Additional changes in precipitation patterns towards more extreme drought and rain periods, as expected with climate change, cause furth
