Detaljerade data är avgörande vid karaktärisering av komplexa förorenade områden. I denna studie utrustar vi ett antal G360-brunnssystem med Star-Oddi milli-TD-tryckgivare i ett mestadels PCE (tetrakloretylen)- och TCE (trikloretylen)-förorenat bostadsområde i Helsingborg. Trots att dessa tryckgivare vanligtvis används inom marina undersökningar gör deras kostnad samt kompakta storlek dem av intre

The Hawkes process, also referred to as a self-exciting point process, is a class of point processes where the intensity is conditioned on previous events. More specifically, an event occurrence excites the process, temporarily increasing the probability of more events occurring. One application of Hawkes processes is to model occurrences of crimes, such as burglaries or shootings. The present the

This paper examines the effect of the recurrent tax on immovable property on wealth distribution. It also investigates how the wealth distributive effect of property prices is affected by the homeownership rate in a country. Data on the mean to median wealth ratio, tax sizes, property prices, homeownership rate, and economic freedom of 36 OECD member countries over the years 2000-2021 are used to

Polybromerade difenyletrar (PBDE) och hexabromcyklododekan (HBCDD) är bromerade flamskyddsmedel som har använts i stor utstäckning i olika produkter under lång tid. Dessa föreningar är svårnedbrytbara och fettlösliga vilket innebär att de kan lagras länge i fettvävnaden. Både kemin och egenskaperna hos PBDE og HBCDD liknar det kända miljögiftet PCB, vilket gör at det är intressant att se närmare pPolybrominated diphenyl ethers (PBDE) and hexabromocyclododecane (HBCDD) are brominated flame retardants. These compounds are lipophilic, persistent and have been shown to bioaccumulate. The Baltic grey seal (Halichoerus grypus) and the Eurasian otter (Lutra lutra) are top predators and especially exposed to high levels of lipophilic pollutant in their diet due to biomagnification. In the current

Tillgång och Effektfrågan – Biogasens Roll i det Gröna Norrbotten Allt fler nyfikna ögon riktas mot Norrland i takt med att den nordligaste landsänden ångar på framåt i utvecklingen mot fossilfria industrier; kommande år planeras miljardinvesteringar i fossilfria tekniker i region Norrbotten, en satsning som kallas den gröna omställningen. Men för att kunna förse etableringarna och samhället med

Climate change is one of the most significant challenges that building sector is confronting. For example, Climate change and associated extreme events are posing a significant challenge for the building sector. Buildings should be prepared to withstand the climate changes and extreme weather that will happen in the future. Designing buildings based solely on past or average weather conditions, wh

Streamflow analysis helps us understand the availability of water resources in a region or a river. Accurate and timely streamflow monitoring is essential to improve our understanding of the hydrological cycle. Streamflow information is also necessary for many applications, such as irrigation planning, watershed management, hydropower products, flood control, and integrated water resources managem

As humans, we experience many spaces/ borders throughout our life flow. The borders of countries, the houses we live in, the borders of a playground, or the borders between two people. Sometimes we shape the borders, sometimes the borders shape us. However, irrespective of the circumstances, these borders exert discernible influences on the trajectory of our life flow. Each of our border experienc

This thesis is designed as exploratory research, with the aim of studying the relatively underexplored and poorly understood theory-practice gap in small-medium enterprises transition from sustainability ideal to practice. While existing literature has extensively addressed theoretical implications, scant attention has been paid to the lived experiences of SMEs, particularly within the context of

Literature reviews from different countries show that the difference between the calculated and measured energy use of the building, often known as “energy performance gap”, can be as high as 100-200%. Knowing the size of the building energy performance gap, if it exists, along with its underlying causes will enable professionals to make more informed assumptions and produce better predictions. As

Biologisk mångfald, varför ska vi bry oss? I nyheter och media blir vi alltmer uppmärksammade på begreppet ’biologisk mångfald’ som ofta presenteras med en negativ klang kopplad till förlust av naturmiljöer. Naturen som utgör grunden för mänsklig välfärd håller på att försvinna, bland annat på grund av mänskliga aktiviteter som urbanisering och moderna jord- och skogsbruksmetoder. Med den ökade urSpending time outdoors during childhood can improve learning, promote pro- environmental behavior, and improve physical and mental health. However, most of our everyday lives are spent indoors and thus a disassociation from nature is created. Paradoxically, a positive relationship between humans and nature is vital for its preservation, and our survival. Through outdoor education in elementary sch
