Popular Abstract in Swedish Vid många industriella processer bildas olika typer av biprodukter, som kan vara mer eller mindre giftiga. En ovarsam hantering av de giftiga ämnena, eller en olycka, kan lätt leda till att den omgivande miljön blir förorenad. Förr, när man var mindre medveten om riskerna med de här ämnena hamnade de ofta i marken kring anläggningarna. Det har resulterat i många förorenBioremediation of soils is considered a low-cost alternative to other remediation techniques. Its ability to remove a number of different pollutants has been demonstrated, relying mainly on the activities of indigenous soil bacteria. The polycyclic aromatic hydrocarbons (PAHs) are considered major environmental pollutants in soil, some of them being toxic and others carcinogenic. Since high-molecu

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

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

BACKGROUND: – The clinical use of risk scores to guide treatment decisions and improve clinical outcomes has rarely been prospectively evaluated. This study aimed to evaluate whether a biomarker-based ABC-AF risk score–guided multidimensional treatment strategy improves long-term outcomes in patients with AF. METHODS: – The multicenter, registry-based, randomized, controlled, open-label study enro

Popular Science SummaryPolymers are giant molecules consisting of a repetition of many small units (monomers) that are linked together by chemical bonds. If we consider a long necklace as a polymer chain, the beads are the monomers and the part of the thread which connects the beads together is the chemical bond. Polymers are important materials in our everyday life and they can be found e.g., in This thesis incorporates studies on the aqueous systems of two types of thermoresponsive amphiphilic block copolymers; a series of nonionic triblock copolymers comprising blocks of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) denoted as PEO-PPO-PEO block copolymers, and a series of ionic diblock copolymers consisting of one charged block and one block of poly(N-isopropylacrylamide) (

The field of research dealing with the integration of biomolecules with electronic elements to form functional devices is called ‘‘bioelectronics’’. Bioelectronics based on mediated electron transfer (MET) between the biological element and the electrodes are designated as “second generation” while the one based on direct electron transfer (DET) is specified as “third generation”. Implanted bioele

B cell lymphomas (BCLs) are a group of severe cancers, afflicting both men and women at different ages. Gene expression profiling (GEP), have during the latest decades fundamentally contributed to a better classification and biological understanding of the different BCLs. Most studies using GEP have analyzed mRNA from tumor tissue constituted of both tumor cells and non-malignant bystander cells.

Vilket membran lämpar sig bäst när det kommer till avskiljning av organiskt material från Bolmenvatten? Med vattendrag som blir brunare och brunare – hur ska våra dricksvattenverk klara av att säkra vårt vatten i framtiden? Svaret heter membranteknik! Vilket membran som passar bäst är däremot en svårare fråga att besvara och således också det som har undersökts i denna studie.In many places across the northern hemisphere, drinking water treatment plants (WTPs) need to avert the effects of deteriorating quality in surface water sources caused by increasing lev-els of natural organic matter (NOM). The two major factors responsible for this phenomenon, also called brownification, are the greenhouse effect and changes in soil acidification. Additional treatment steps needs

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.

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 changing customers’ behavior nowadays strongly affects the market situation in any type of industries. Markets are demanding a shorter delivery lead time, shorter product life cycle and higher flexibility to fulfill customers’ expectation. In order to fully adapt in this kind of situation and maintain competitiveness in the market, a company need to have better collaboration internally and ext

Cancer är en vanlig sjukdom i dagens samhälle, och man estimerar att en av tre i Sverige någon gång i livet kommer få en cancerdiagnos. De stora framsteg som skett inom forskning och teknologi har gjort att man har blivit bättre på att behandla så att allt fler överlever sin sjukdom. Det finns dock studier som tyder på att personer med samma diagnos kan reagera olika på samma typ av behandling. VaPurpose: In an era of personalized oncology where the aim is to give every patient the right treatment at the right time an area of promising research is emerging called radiomics, or quantitative image analysis. The main underlying hypothesis is that pathophysiological information can be found in image texture not visible to the bare eye that can improve diagnosis, treatment adaption or be linked

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

Strålbehandling är en viktig behandling av cancer och det är avgörande att ge de föreskrivna stråldoserna exakt på rätt plats för att lyckas. Innan en patient behandlas verifieras strålbehandlingen genom kontrollmätningar. Dessa kontrollmätningar utförs med små detektorer som är placerade i ett fantom. Dessa mäter dosen endast i de punkter där de placeras. Stråldosen som ligger mellan dessa punkteBackground & Purpose: Radiation therapy is an essential treatment for cancer patients with the ultimate goal to deliver radiation doses to the tumour with precision while minimizing exposure to surrounding healthy tissues. Treatment verification is crucial to ensure the accuracy of radiation delivery, for instance by measuring the radiation dose distribution. Among various dosimetry techniques

Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields. To overcome process instability a

Från och med 2022 ställer Boverket krav på att klimatpåverkan från nyproducerade byggnader ska redovisas uttryckt i kg koldioxidekvivalenter per kvadratmeter bruttoarea. Den s.k klimatdeklarationen utgår från livscyklisk metodik där produktskedet och byggproduktionsskedet omfattas. I klimatdeklarationen ska även periodiskt underhåll och livslängder för klimatskalet noteras. Många branschaktörer arAs of 2022, the Swedish National Board of Housing, Building and Planning (Boverket) is requiring that the climate impact from newly developed buildings has to be calculated and reported in terms of kg carbon dioxide equivalents per m² of gross area. The so-called climate declaration is based on life-cycle methodology and covers the product stage and the construction process stage. Periodic mainten

Salinisation is a global issue which leads to desertification and soil degradation and exposure to salt is also known to inhibit microbial activity and plant growth. This study was conducted to determine the influence of salinity on microbial activity of a non- saline soil. By using Salt Induced Community Tolerance (SICT) concept I found that microbial community tolerance to salt can be induced in

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

Vid en diskussion om nivån på den svenska bolagsskatten är det av stor vikt att avgöra huruvida diskussionen rör den nominella eller den effektiva skattesatsen. Den nominella skattesatsen uppgår till 28 procent och återfinns i 65 kap. 14 § IL. Den effektiva skattesatsen är däremot inte given utan kan i viss utsträckning påverkas, eftersom den bestäms genom att dividera skatt på årets resultat med
