Effect of a single nanosecond pulsed discharge on a flat methane–air flame

Successful implementation of plasma-assisted combustion in applied thermal processes heavily relies on how the plasma can be formed as it interacts with the reactive flow and what the effects are of such a plasma on the combustion process. The current study is an experimental investigation of a plasma-assisted lifted flat methane–air flame by a nanosecond pulsed discharge at atmospheric pressure.

3D-tomographic reconstruction of gliding arc plasma

his study presents three-dimensional (3D) emission tomography on gliding arc discharge for volumetric measurements of plasma luminosity fields. The 3D tomography of the plasma luminosity field enables quantification and characterization of 3D plasma features, which are not easily accessible in two-dimensional measurements. Simultaneous projections of the plasma discharge were imaged using multiple

Combined solar and membrane drying technologies for sustainable fruit preservation in low-income countries – prototype development, modelling, and testing

This investigation consisted of developing and evaluating solar dryers together with semi-permeable membrane pouches for drying juicy fruits in low-income tropical countries. Two design iterations were carried out including prototype modelling and testing. The latest developed solar dryers were a passive and an active solar dryer. Modelling was initially carried out mathematically using an equatio

PARP14 is a writer, reader, and eraser of mono-ADP-ribosylation

PARP14/BAL2 is a large multidomain enzyme involved in signaling pathways with relevance to cancer, inflammation, and infection. Inhibition of its mono-ADP-ribosylating PARP homology domain and its three ADP-ribosyl binding macro domains has been regarded as a potential means of therapeutic intervention. Macrodomains-2 and -3 are known to stably bind to ADP-ribosylated target proteins, but the func

PARP14 is a PARP with both ADP-ribosyl transferase and hydrolase activities

PARP14 is a mono-ADP-ribosyl transferase involved in the control of immunity, transcription, and DNA replication stress management. However, little is known about the ADP-ribosylation activity of PARP14, including its substrate specificity or how PARP14-dependent ADP-ribosylation is reversed. We show that PARP14 is a dual-function enzyme with both ADP-ribosyl transferase and hydrolase activity act

Long-term speech outcome after anterior distraction osteogenesis of the maxilla in patients with cleft lip and palate

Advancement of the maxilla may increase the distance between the soft palate and the posterior pharyngeal wall in patients with cleft lip and palate, implying a risk of velopharyngeal dysfunction. The aim was to evaluate long-term speech outcome in a consecutive series of patients treated with distraction osteogenesis (DO). Fourteen out of the 16 patients agreed to participate. A long-term speech

Communicating a sense of safety: the public experience of Swedish Police Instagram communication

The research aim of this article is to generate novel insights into how public sector organizations (PSOs) strategically communicate with the public about critical issues on social media. To this end, the study explores the public's experiences of the Swedish Police's sense of safety communication on Instagram in the third largest city in Sweden, where the lack of a sense of public safety is a mai

Stabilization of Evanescent Wave Propagation Operators

This paper presents a stabilized scheme that solves the wave propagation problem in a general bianisotropic, stratified medium. The method utilizes the concept of propagators, i.e., the wave propagation operators that map the total tangential electric and magnetic fields from one plane in the slab to another. The scheme transforms the propagator approach into a scattering matrix form, where a spec

Integration support for temporary protection holders

The Temporary Protection Directive does not contribute to an effective integration process. Measures to facilitate refugee integration need to be put in place even if return is the preferred durable solution.

Sensemaking in chemistry at upper secondary school

In chemistry education, student learning difficulties involve connecting theory and phenomena to make sense of chemistry, as well as utilising and understanding the language of chemistry. In this thesis, I examine the relationships among student language use, previous achievement level, and sensemaking in chemistry, as well as how experienced teachers help students make sense of chemistry as part

Network reconfiguration for renewable generation maximization : Application of a power-flow optimization algorithm on a distribution network in southern Sweden

Increasing the amount of renewable generation in distribution networks is a fundamental part of the energy transition. Multiple methods exist to increase the hosting capacity in a grid, to allow larger injections of generation and more efficiently utilize existing infrastructure before operational limits are breached. In this thesis, the method studied for this is network reconfiguration. Many dis

NPM? No thanks-We want bureaucracy!

This chapter includes an analysis how three major Swedish cities manage their strategy and control during transformative and complex capacity challenges. In particular, it extends our knowledge and contributes to NPM research concerning why and how local governments chose to adopt certain strategies and control actions to manage external pressure from a growing population. This is accomplished by

Biomarker Records of Environmental Shifts on the Labrador Shelf During the Holocene

The ultimate demise of the Laurentide Ice Sheet (LIS) and the preceding and succeeding oceanographic changes along the western Labrador Sea offer insights critically important to improve climate predictions of expected future climate warming and further melting of the Greenland ice cap. However, while the final disappearance of the LIS during the Holocene is rather well constrained, the response o
