Vitiation refers to the condition where the oxygen concentration in the air is reduced due to the mix of dilution gas. The vitiation effects on a premixed methane flame were investigated on a swirl-stabilized gas turbine model combustor under atmospheric pressure. The main purpose is to analyze the combustion stability and CO emission performance in vitiated air and compare the results with the fl
Cementproduktion står idag för en ansenlig andel av världens koldioxidutsläpp, vilket driver utvecklingen av bindemedel med lägre koldioxidutsläpp. För utsläppen i ett längre perspektiv är dock de nya bindemedlens beständighet absolut avgörande. De flesta nedbrytningsmekanismer är direkt relaterade till både fukt- och jontransport. Dessa processer har undersökts i många studier, men huvudsakligen Cement production is responsible for a significant portion of manmade CO2 emissions. This motivates the development of cementitious binders with a lower carbon footprint. Considering the emissions in a longer perspective, the durability of concrete structures is absolutely essential. Most degradation of concrete structures is closely related to both moisture transport and ion transport. Many studi
The aim of this paper is to describe and explain how smartphone apps,designed to assist consumers in making informed ethical choices andgreening their everyday practices, enable and shape ethical consumption.Taking a socio-material approach and drawing on an ethnographic studyof three ethical consumption apps – the Green guide, the Fair trade appand Shopgun – the paper shows that these digital dev
In this paper, we will present some of our findings from a study conducted on legislative measures related to the online infringement of intellectual property rights commissioned by the European Union Intellectual Property Office (EUIPO) on legislative measures related to online intellectual property rights infringements. The present summarizes the mapping the existing legislative national measure
We present large-eddy simulation (LES) of a high-pressure gas jet that is injecting into a quiescent inert environment. The injection is through a nozzle with a diameter of 1.35 mm. Four injection strategies are considered in which the results of a single continuous injection case are compared with those of double injection cases with different injection splitting timing. In all double injection c
The cortico-basal ganglia-thalamic (CBT) circuit is thought to be involved in control of voluntary and goal-directed movements and action selection. Dopamine is known to play a crucial role in this circuit and regulating its activity. The important role of dopamine is particularly evident in Parkinson’s patients, where dopaminergic cells are dying and motor impairments follow. While dopamine repla

ObjectivesThe aim was to describe the clinical characteristics and epidemiology of hypocomplementaemic urticarial vasculitis (HUV; anti-C1q vasculitis) in two geographically defined areas of Sweden.MethodsIn the health-care districts surrounding Skåne University Hospital (mean population 950 560) and Linköping University Hospital (mean population 428 503), all incident cases of HUV residing within
Objective: To systematically evaluate variations in single-nucleotide polymorphisms within 13 candidate pain genes in patients differing in phenotype characteristics based on a composite measure of pain sensitivity.Methods: In a case-control study, 149 patients scheduled for laparoscopic cholecystectomy were individually categorized according to preoperative pain sensitivity and postoperative pain
Proton exchange membrane fuel cells (PEMFCs) are considered as the mostpromising alternative power sources with a wide variety of applications owing to their attractive advantages compared to other conventional power sources. During the past decades, the cell performance has been gradually improved. However, the cell performance improvement and cost reduction are still urgently needed due to the r
Trots den snabba utvecklingen av moderna tekniker för narkos och bedövning upplever många patienter smärta efter kirurgi. God smärtlindring efter en operation kan påskynda återhämtningen och därmed minska risken för komplikationer som blodpropp eller infektion. För att uppnå detta måste vi bli bättre på att hitta individer med ökad risk för postoperativ smärta redan innan de sövs. Sedan tidigare kMany patients experience pain after surgery. Postoperative pain may lead to delayed mobilization, persisting pain, and psychosocial distress. Others are given excessive analgesic doses and experience side effects. More optimal use of pain relief has several advantages, such as faster postoperative mobilization and fewer incidents of venous thromboembolism or infection. To achieve this, we must ide
