Background Global research suggests that persons with disabilities face barriers when accessing health care services. Yet, information regarding the nature of these barriers, especially in low-income and middle-income countries is sparse. Rural contexts in these countries may present greater...

Ruthenium based catalysts for ammonia synthesis have been studied extensively following the industrial adoption of a promoted carbon supported ruthenium catalyst in the Kellogg Advanced Ammonia Process (KAAP). Nevertheless, there are still fundamental aspects such as the dissociative adsorption...

Non-Newtonian fluids having Bingham or power-law rheology are common in many applications within drilling and reservoir engineering. Examples of such fluids are drilling muds, foams, heavy oil, hydraulic-fracturing and other stimulation fluids, and cement slurries. Despite the importance of non...

Dette bladet omhandler systemer med våtromsplater av ekstrudert polystyren (XPS). Platesystemene fungerer som membran og noen systemer fungerer også som dampsperre i våtrom. Platene dekkes av fliser. Systemene brukes som regel på vegger, men det fins også enkelte gulvsystemer....

In petroleum drilling, cuttings transport problems, i.e. an accumulation of drilled of solids in the wellbore, are a major contributor to well downtime and have therefore been extensively researched over the years, both experimentally and through simulation. In recent years, Computational Fluid...
