Personuppgifter och användarinformation har länge använts av företag som en grund för att kunna optimera och utveckla tjänster. I takt med internets explosionsartade framväxt har dock denna användning kommit att få ett större kommersiellt värde än någonsin tidigare. Detta på grund av att teknikens utveckling har medfört att allt större delar av vår vardag sker i anslutning till en internetuppkoppl

We are daily moving in different landscapes for various reasons; sometimes we are looking for specific activities and sometimes just to move from one place to another. Common for this is the affect the landscape can have on us and how it gives us different experiences. In this essay I seek answers to what is important for people when they visit the nature for recreational purposes. What factors do

The major histocompatibility complex (MHC) is a membrane protein group of central importance in the immune system. It is divided into two main classes, class I and class II. The MHCs are highly polymorphic which is believed to be indication of trans-species polymorphism (TSP). There is TSP when an allele is maintained in two species through a speciation event. The songbirds that I study here belon

Detta är en artikel om kalkmodifiering av lermorän och är baserad på examensarbetet ”Lime modification of clay till – a case study” (Westesson, 2015). Med kalkmodifiering menas att jordens packningsbarhet förbättras genom inblandning av kalk. Metoden att använda sig av kalk för att förbättra de geotekniska egenskaperna av leror och lermoräner är en nygammal metod och har främst använts till vägproThis report deals with lime modification of clay till. Lime modification means that the compaction properties of the soil are improved by the addition of lime. The report consists of three main parts: 1) Description of the geotechnical properties of clay till and how lime modification affects the properties; 2) Description of the implementation of lime modification and the tests conducted at a con

In our everyday life we live distant from the origin of life itself - nature. Dramatic landscape and fascinating views touch us in a way that few other things manage to do. It is something that make us recognize our powerlessness and the feeling of awe towards the nature. Experiencing striking nature is a way to create a deeper understanding of our own world and at the same time enrich our lives w

”Most of Sweden’s surface is covered by forest, 68 percent is woodland; the built-up and landscaped land does not make up more than 3 percent of Sweden’s total land area. About 50% of the forest land is made of pine (Pinus sylvestris), making it the most common tree species in the country’s forests.” In the 70s, a design movement was established in Swedish homes “ Svensk fur”. It was cheap, hones

As a result of 20th-century car-centric planning, many urban districts had emerged designed to serve only one function. Different residential suburbs and trade areas were dispersed scattered within and outside the cities. This has led to more dependence on private cars to meet people’s daily needs. Urban Ergonomics will discuss one type of these areas, the external shopping centers, or the big-bo

As the demand for eco-friendly alternatives to traditional plastics grows, Polyethylene Furanoate (PEF) emerges as a promising solution. Derived from renewable biomass sources, PEF embodies sustainability principles by reducing reliance on finite resources and minimizing environmental impact. PEF is synthesized from 2,5-furandicarboxylic acid (FDCA), a key monomer which upon polymerization has the

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

Nowadays it has become relevant for scientists to understand the impact of tropical forest structure on the Global Carbon Cycle. Dynamic vegetation models have been developed to pursue this issue, specifically by improving algorithms that could analyze the allometry, biomass content and mortality rate of each singular simulated plant individual and how this responds to climate change, management aCompetition between neighbouring trees has a big impact on their growth. Trees have different strategies to deal with competing neighbours. Some grow quickly and tall, overshadowing neighbouring trees, but die young (Georges K., 2015). Others grow more slowly, but outlive the fast-growing ones and cast shade on them over a longer period. These interactions have a strong influence on the dynamics o

A large share of the existing building stock in Sweden originates from the so-called Million Building Programme, a large-scale construction wave between 1965 and 1974 to tackle the housing shortage at this time. Those buildings have very high energy demand and require renovation due to age and often neglected maintenance. The Swedish government’s long-term climate and energy goals are tied to an e

Bygg- och fastighetssektorn står för stora utsläpp av växthusgaser från byggnadsmaterial- och energianvändning. Byggbranschen står idag för ca en femtedel av Sveriges totala koldioxidutsläpp. Ett område med stor potential är byggnadsmaterial där IsoTimber är ett av företagen som driver utvecklingen framåt. IsoTimber är en relativt ny aktör inom byggsektorn som tillverkar prefabricerade väggar i trThe construction and real estate sector accounts for a large part of the emission of greenhouse gases from the usage of building material and energy. The construction industry today accounts for about one-fifth of Sweden’s total carbon dioxide emissions. One area with great potential is building materials where IsoTimber is one of the companies that drive the development forward. IsoTimber is a re
