Even though anthropogenic nano-sized tungsten carbide nanoparticles (WC NPs) have been found in the environment, there are currently no investigations on their environmental fate. This work studies the interaction between natural organic matter (NOM) and WC NPs, as well as the potential uptake by the aquatic model organism Daphnia magna. We here show that the affinity between WC NPs and humic acid

Large Eddy Simulation (LES) was employed to investigate the flow field characteristics in an ethylene fueled scramjet combustor with a rearwall-expansion cavity in both non-reaction and reacting flows. The numerical solver was first validated against experiments and the numerical results were shown in reasonably good agreement with the available experimental data. Characteristics of the flow field

n this paper I will use concepts from innovation theory to analyse the work of the Court of Justice of the European Union in its important role as sole interpreter of EU law. In that regard, I define ‘innovator’ as one that facilitates use of new or existing inventions. Thus innovation is portrayed as a process in which several actors may contribute and where it all starts with an invention (the s

Older people with arrhythmias comprise a large group requiring complex care, posing many healthcare challenges. Rapid growth of the older population demands a better understanding of the needs of this patient group. The aim of this thesis was to investigate arrhythmia prevalence, incidence, survival, and experiences from the perspective of a geriatric population (aged 60+ years), and to examine th

Jordan population have increased 3 million in the last five years. 1.5Million are refugees from Syria. 800 thousand are inside refugeecamps in the northern part of Jordan. 100 thousand are situated inZaatari camp which is located 10 kilometres east of Mafraq city. Thisenormous influx increased solid waste volume generated by 480 tonsdaily. The additional waste generation has exacerbated pre-existi

The present study uses RSM (Response Surface Methodology) to verify the fusibility of bottom ash from coal industry, and efficient flux between, calcium oxide (CaO), lithium oxide (Li2O) and sodium oxide (Na2O). The bottom ashes,have demonstrated the possibility to be used in the development of glass-ceramics, and glassy materials, due to the presence of high concentrations of aluminum silicates.

Semiconductor nanowires show a great deal of promise for applications in a widerange of important fields, including photovoltaics, biomedicine, and informationtechnology. Developing these exciting applications is strongly dependent onunderstanding the fundamental properties of nanowires, such as their opticalresonances and absorption spectra. In this thesis we explore optical absorption spectra of

Mitochondrial biogenesis and function in plants require the expression of over 1000 nuclear genes encoding mitochondrial proteins (NGEMPs). The expression of these genes is regulated by tissue-specific, developmental, internal, and external stimuli that result in a dynamic organelle involved in both metabolic and a variety of signaling processes. Although the metabolic and biosynthetic machinery o
