The idea of energy efficient, healthy buildings has existed since 1970s. However, a one-dimensional approach for many housing issues does not assure sustainability. Therefore, near the end of the 20th century, the built environment became a focus of attention within the environmental movement with wider focus on building certification schemes and sustainability issues such as interrelationships be

Under de senaste 100-200 åren har tall (Pinus sylvestris) etablerats på många sydsvenska mos- sar. Eftersom tall trivs i relativt torra och näringsrika miljöer, ger detta en indikation på att grundvattennivån i mos- sarna har sänkts. Tre mossar i Kronobergs län, Småland, har valts ut för en dendrokronologisk och torvstratigrafisk undersökning för att se om det finns ytnära torvlager som vittnar omScots pine (Pinus sylvestris) can be found growing in many raised bogs in Småland, south Sweden, and these trees have been established during the last 100-200 years. Because pine prefers a relatively dry environment rich in nutrients, its presence indicates a lowering of the groundwater table. Three bogs in south Sweden were in- vestigated with dendrochronologic and peat stratigraphic methods to d

En sedimenttransekt bestående av tio punkter borrades med hjälp av en ryssborr i alkärret vid Kalvöviken på Biskopsmålahalvön i centrala Blekinge. I huvudpunkten togs tre parallella 1 m långa borrkärnor. Sedimentprov togs ur borrkärnorna och undersöktes med hjälp av glödförlust, mineralmagnetiska-, makrofossil-, pollen- och strukturanalyser. Kronologin fastställdes genom två kol-14-dateringar kompA sediment transect based on ten corings were performed with a Russian peat corer in the aldercarr at Kalvöviken on the Biskopsmåla Peninsula in central Blekinge. Three parallel sediment cores were collected at the master coring point. These cores were subsampled and studied by means of loss of ignition (LOI), mineral magnetic measurements, macrofossil analysis, pollen analysis and structural anal

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

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

Forest ecosystems are important actors in climate change mitigation strategies through their abilities to act as both carbon sinks and sources. The commonly used forest management strategy of clearcutting has been suggested to be paired with large greenhouse gas emissions, increasing the need for research on the climate effect from alternative management strategies. Rumperöd forest is managed thro

This study looks at the change of the Urban Heat Island (UHI) intensity in Rio Park, Madrid, which during the course of the last 20 years has in essence been retransformed from an urban highway into a flourishing green park along the Manzanares river. The deconstruction of the M-30 highway started in 2005, was completely finished in 2015, and canopy growth in the area continued during the followin

Bacterial cellulose (BC) is a versatile and biocompatible polysaccharide produced by bacteria, with Komagataeibacter xylinus being the model species for its production. This polymer has unique properties that make it valuable in several applications, including as a rheology modifier in cosmetics. Cellugy, a Danish start-up, produces EcoFLEXY, a BC-based rheology modifier that enhances the viscosit
