Populärvetenskaplig sammanfattning Arsenik finns överallt i naturen och släpps även ut genom industrier. Det är ett klassiskt gift som färgat historien, men som även använts inom medicin. Arsenik är det enda kemiska cancerogena ämne som ger hudcancer vid förtäring. Det har även använts inom industrin under en lång tid, och deponering av arsenikhaltigt material kommer att orsaka stora miljöproblem.Arsenic is present everywhere in the world. It is found in the bedrock and is discharged by industries. Differents forms of arsenic varies in toxicity, the inorganic form is much more toxic then the organic form. The inorganic form is most common in drinking water and groundwater, meanwhile the inorganic form can occasionally be found in reasonable large quantities in fish and seafood. Today milli

I den här uppsatsen undersöker vi vilka utmaningar sju svenska kommuner har stött på i sitt arbete med sociala medier. Genom intervjuer med tolv personer som arbetar med information och kommunikation i sina respektive kommuner har det framkommit ett antal utmaningar som har analyserats genom ett neoinstitutionellt perspektiv. Neoinstitutionalismen förklarar hur organisationer agerar för att anses

A high excess mortality is well described after hip fracture. Deaths are in part related to comorbidity and in part due directly or indirectly to the hip fracture event itself (causally related deaths). The aim of this study was to examine the quantum and pattern of mortality following hip fracture. We studied 160,000 hip fractures in men and women aged 50 years or more, in 28.8 million person-yea

Weight loss is an important complication of Huntington's disease (HD), however the mechanism for weight loss in HD is not entirely understood. Mutant huntingtin is expressed in the gastrointestinal (GI) tract and, in HD mice, mutant huntingtin inclusions are found within the enteric nervous system along the GI tract. A reduction of neuropeptides, decreased mucosal thickness and villus length, as w

Reduction of packaging waste has been a European target for more than 40 years. However, packaging is indispensable for protecting what it carries. In this study, an analysis of the European regulations on packaging and of their resulting effect on recycling performance was performed by means of a literature survey and the national results published in the European Database, Eurostat. Based on the

Familial renal glycosuria is an inherited disorder resulting in glucose excretion in the urine despite normal blood glucose concentrations. It is most commonly due to mutations in the SLC5A2 gene coding for the glucose transporter SGLT2 in the proximal tubule. Several drugs have been introduced as means to lower glucose in patients with type 2 diabetes targeting SGLT2 resulting in renal glycosuria

Vehicle-to-vehicle (VTV) wireless communications have many envisioned applications in traffic safety and congestion avoidance, but the development of suitable communications systems and standards requires accurate models for the VTV propagation channel. In this paper, we present a new wideband multiple-input-multiple-output (MIMO) model for VTV channels based on extensive MIMO channel measurements

Building owners are encouraged to reduce energy use in order to both contribute to national energy-saving goals and reduce the costs of heating and operation. It is important to choose the most optimal renovation measures available so as to achieve cost-effective energy use while maintaining excellent indoor environments, without sacrificing architectural quality or negatively affecting the enviro

Hypertension is a multifactorial disease in which the interplay of genetic and environmental factors that maintain blood pressure stable throughout life is altered. Cytochrome P450 (CYP)-derived metabolites of arachidonic acid such as epoxyeicosatrienoic acids (EETs) and 20-hydroxyeicosatetraenoic acid (20-HETE), active on vascular tone, endothelial function and renal sodium reapportion, have been
