Impact of vitiation on a swirl-stabilized and premixed methane flame

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

Experimental studies of ion transport in cementitious materials under partially saturated conditions

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

Agencing ethical consumers: smartphone apps and the socio-material reconfiguration of everyday life

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

Intellectual Property Rights in a Digital Environment : An EU Wide Mapping of Available Legislative Enforcement Measures

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

The Effect of Splitting Timing on Mixing in a Jet with Double Injections : A Large-Eddy Simulation Study

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 Relevance of Sexual Dysfunction Related to Groin Pain After Inguinal Hernia Repair : The SexIHQ Short Form Questionnaire Assessment

Background: Chronic postoperative pain after inguinal hernia surgery can affect sexual function. A new short form questionnaire for inguinal hernia pain related sexual dysfunction (SexIHQ) was introduced and applied to a register based cohort of total extra-peritoneal hernioplasty (TEP) operated patients. Methods: Sexually active men, 30–60 years old, recorded in the Swedish Hernia Register for a

How task demands influence scanpath similarity in a sequential number-search task

More and more researchers are considering the omnibus eye movement sequence—the scanpath—in their studies of visual and cognitive processing (e.g. Hayes, Petrov, & Sederberg, 2011; Madsen, Larson, Loschky, & Rebello, 2012; Ni et al., 2011; von der Malsburg & Vasishth, 2011). However, it remains unclear how recent methods for comparing scanpaths perform in experiments producing variable

Microsaccade detection using pupil and corneal reflection signals

In contemporary research, microsaccade detection is typically performed using the calibrated gaze-velocity signal acquired from a video-based eye tracker. To generate this signal, the pupil and corneal reflection (CR) signals are subtracted from each other and a differentiation filter is applied, both of which may prevent small microsaccades from being detected due to signal distortion and noise a

Rules of engagement - Regulation of complement response in tissue

Always in motion and probing for danger, complement proteins are found in every space and notch of the body. Their omnipresence combined with an ability to wreak havoc when activated, mandates a strong leash! The how, when, and where to unleash or constrain the complement response remain partly answered questions, despite the significant progress made in the field in the past 100 years.The work in

Working towards paradise; an interdisciplinary theoretical framework for environmental peacebuilding

Exploring the human-environment nexus and linkages between (post-conflict) political developments and environmental dimensions, this paper reflects on the development of interdisciplinary theories of environmental peacebuilding. Theories of environmental peacebuilding come from a variety of different disciplines within the social and biophysical sciences; warfare ecology (Machlis et al. , 2011), e

Every day peace: the ignored role of Civil Society in the Syrian Uprising

This paper discusses the role of civil society in the Syrian war between 2012 and 2016, specifically in the so-called "liberated areas" under the control of the Free Syrian Army and the Syrian opposition. A postdoctoral research project of Copenhagen University between 2014 and 2016, has investigated the role of citizen video journalists and peaceful activists in the Syrian uprisings. Responding t
