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. Syvab är ett kommunalt bolag som driver Himmerfjärdsverket men ansvarar också för någrSludge is produced in conventional waste water treatment. 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

Background The colonisation of Australia led to a lot of suffering and sorrow for an uncountable amount of Indigenous people. Due to the forced change of lifestyle and diet during and after the colonisation, conditions like obesity and type 2 diabetes became commonly occurring. Still today there is a higher burden of these conditions, but also of depression and anxiety, in this group of people. Fu

Bättre pollinering ger större avkastning av chili Blommor och bin. Vem har inte hört berättelsen om blommor och bin som liten? Nej, det kanske inte är några bin inblandade när ett människobarn blir till, men det är sanningen för en del växter, inklusive många av våra grödor. De är i varierande grad beroende av bin för sin reproduktion. Vår befolkning växer sig allt större och vi behöver allt stör

Mot bakgrund av de globala klimatambitionerna har den folkrättsliga traktaten Energistadgefördraget (ECT) kommit att ifrågasättas med ökande intensitet. I synnerhet anses Investor-State Dispute Settlement (ISDS) mekanismen i artikel 26 ECT inskränka staters rätt att lagstifta och därigenom bromsa utfasningen av fossila energislag (regulatory chill). En ISDS-mekanism är vanligt förekommande i gränAgainst the backdrop of global climate ambitions, the international treaty known as the Energy Charter Treaty (ECT) has come under increasing scrutiny. In particular, the Investor-State Dispute Settlement (ISDS) mechanism in Article 26 ECT is seen as restricting states' right to legislate and thereby slow-ing down the phasing out of fossil fuels (regulatory chill). ISDS is a common mechanism

Sand and dust storms (SDS) represent a significant and widespread obstacle to sustainable development, affecting its economic, social, and environmental dimensions. SDS pose severe challenges to achieving several Sustainable Development Goals (SDGs), including the eradication of poverty, the achievement of zero hunger, the improvement of health and well-being, the provision of clean water and sani

Cement är ett av världens mest använda material och agerar som bindemedel i betong och murbruk. Portlandcement, som är den mest förekommande typen av cement, produceras årligen i en kvantitet av fyra miljarder ton. Cementproduktionen står för ca 7 % av de globala koldioxidutsläppen och det finns ett stort intresse i att hitta alternativa vägar och optimeringsmöjligheter, för att minimera klimatpåvCement is one of the world's most used materials and acts as a binder in concrete and mortar. Portland cement, which is the most common type of cement, is produced annually in a quantity of four billion metric tons. Cement production accounts for approximately 7 % of the global carbon dioxide emissions and there is a great interest in finding alternative routes and optimization possibilities,

The Swedish power grid is experiencing an ever-growing challenge to efficiently balance the grid. An increasing share of intermittent generation, decreased system inertia, continued electrification and more distributed energy resources result in an increasing need for flexibility. Smart grid technologies have, amongst other applications, shown to be a possible solution to this increased need for f

Economic sanctions are defined as the exercise of pressure by one state to bring about a change in political behaviour of another state. Traditional economic sanctions are directed at the entire population of the sanctioned country while targeted sanctions are directed at the State’s government and/or individuals. Iran has become a sanction target first in 1979, which was imposed by United States

ims In atrial fibrillation (AF), a relation between electrocardiogram (ECG) fibrillatory wave amplitude and thrombus formation has been sought for long with conflicting results. In contrast, the possible relation between atrial fibrillatory rate obtained from the surface ECG and left atrial thrombus formation in patients with AF is unknown and was consequently evaluated in this study. Methods and

A REE-bearing fluorosilicate from the Tommot REE-Nb deposit in Yakutia, Russia, described without a name in 1966, is characterized here as a new species, proshchenkoite-(Y), of the vicanite group of borosilicates. Wavelength-dispersive electron probe analyses gave the following empirical formula: (Y3.70REE7.54Ca1.55Na1.16Mn0.77Th0.10Pb0.01)(Sigma 14.83)(Fe0.832+M0.15Ti0.02)(Sigma 1.00)Ca-1.00 (P0.

Clinically, hemodilution to a hematocrit of 9% has been studied, but the effects of hypovolemia during this degree of hemodilution have not been elucidated. We studied the response to blood loss during extreme hemodilution and evaluated indicators of hypovolemia. Systemic and myocardial hemodynamics, oxygen transport, and blood lactate concentrations were measured in 12 anesthetized pigs exposed t

Background: There are several risk factors for the colonisation, infection and spreading of antibiotic resistant bacteria among elderly residents of nursing homes. An updated estimate of the native prevalence of antimicrobial resistance in uropathogens among Swedish nursing home residents is needed. Methods: Urine specimens were collected for culture and antimicrobial susceptibility testing agains

Objective The complex genetic aetiology underlying irritable bowel syndrome (IBS) needs to be assessed in large-scale genetic studies. Two independent IBS cohorts were genotyped to assess whether genetic variability in immune, neuronal and barrier integrity genes is associated with IBS. Design 384 single nucleotide polymorphisms (SNPs) covering 270 genes were genotyped in an exploratory cohort (93

Uncultivated field margins are one of the most frequent non-crop habitat types in contemporary, highintensity agricultural landscapes and may therefore be important for the persistence of many farmland species. Managing field margins in a way that preserves, and preferably enhances, their value for biodiversity is therefore important. In the present study, we evaluate how the flora of uncultivated

The road haulage sector experiences a considerable amount of inefficiency, characterised by sub-optimal utilisation of an individual vehicle’s cubic load fill and weight hauling capacity. This study firstly aims to understand why – despite its evident economic and environmental cost – this phenomenon has existed over the years. Next, an overview of initiatives and opportunities for improving freig

Background: It has been suggested that neuromuscular function is of importance in the overall outcome after anterior cruciate ligament (ACL) injury. Hypothesis: Good neuromuscular function can be achieved and maintained over time in subjects with ACL injury treated with rehabilitation and activity modification but without reconstructive surgery. Study Design: Case series; Level of evidence, 4. Met

Popular Abstract in Swedish Det övergripande syftet för den här avhandlingen var att identifiera miljöfaktorer som påverkar barn med ADHD, autism och Downs syndrom och deras förmåga att koncentrera sig i sin lärmiljö i skolan. Målet med den forskning som gjorts här är inte att avskriva några av de extraresurser som barnen ifråga behöver, utan i stället att ge förslag på hur man kan utforma deras lThe overall aim of this thesis was to identify environmental factors that affect children with ADHD, autism, and Down's syndrome and their ability to concentrate in their learning environment at school. The issue of this research is not to dismiss any of the additional resources these children are in need of; instead it is to suggest how to arrange learning environments in the most supportive way

Studies on short-term prognosis of venous thromboembolism (VTE) that take family history of VTE and Charlson Comorbidity Index (CCI) into account are sparse. The aim was to investigate the importance of family history of VTE and CCI for short-term mortality after a first episode of VTE. Using Swedish medical databases, we conducted a 90-day nationwide cohort study of 41,700 Swedish born patients w
