The breakup of a liquid jet into irregular liquid structures and droplets leading to the formation of a dilute spray has been simulated numerically. To overcome the shortcomings of certain numerical methods in specific flow regimes, a combined approach has been chosen. The intact liquid core, its primary breakup and the dense spray regime are simulated using the volumes of fluid (VOF) method in co
Birgitta of Sweden (Birgitta Birgersdotter, 1302/03-1373) and her younger contemporary Catherine of Siena (Caterina Benincasa, 1347-1380) form the most powerful and influential female duo in European history. Both enjoyed saintly reputations in life, while acting as the charismatic leaders of a considerable group of followers consisting of clergy as well as mighty secular men and women. They are a
Neutrino oscillations constitute an excellent tool to probe physics beyond the Standard Model. In this paper, we investigate the potential of the ESSnuSB experiment to constrain the effects of flavour-dependent long-range forces (LRFs) in neutrino oscillations, which may arise due to the extension of the Standard Model gauge group by introducing new U(1) symmetries. Focusing on three specific U(1)
The Nordic countries Sweden and Denmark have a long and intertwined history. The Second World War, though, formed different experiences in the two countries that led to diverging paths in the Cold War. Denmark became a member of North Atlantic Treaty Organization, while Sweden stayed non-aligned. Thus, it can be assumed that Denmark was more likely to adopt Western foreign policies and doctrines t
Over the last few years, there has been a proliferation of different kinds of movements across the globe as citizens agitate for economic, socio-political and environmental change. In the Democratic Republic of Congo (DRC), where the country has been involved in a series of wars, attention has rather been eschewed towards the rape and sexual violence of women and girls. Using post-colonialism and
This paper presents a computational study of the effects of fuel and thermal stratifications on homogenous charge compression ignition (HCCI) combustion process in a personal car sized internal combustion engine. Stratified HCCI conditions are generated using a negative valve overlap (NVO) technique. The aims of this study are to improve the understanding of the flow dynamics, the heat and mass tr
Because of the increasing demand of low polluting and efficient diesel engines, numerous studies related to the different processes that take place in them are being carried out. This study treats the direct injection of fuel at high pressures (c.a. 1500 bar). Ignition is not simulated in this work since this is intended to be a previous step for future studies which include combustion. A combinat
Eosinophils participate in the inflammatory response seen in allergy and helminthic infestation. Their release of granule-bound cationic proteins may play a role in these diseases. Therefore, we investigated mechanisms involved in the release of eosinophil cationic protein (ECP). Serum-opsonized zymosan was phagocytosed by eosinophils, and ECP was released into the phagosomes as judged by immunoel
In the equation for thermal energy output from a flat-plate solar collector (written as a function of the collector mean heat carrier temperature), both the gain and the loss terms are multiplied by the collector efficiency factor, F'. For a concentrating collector with an uneven (non-uniform) irradiation on the absorber, the efficiency factor for the gain term, here called the optical efficiency
The M protein of Streptococcus pyogenes is a major bacterial virulence factor that confers resistance to phagocytosis. To analyze how M protein allows evasion of phagocytosis, we used the M22 protein, which has features typical of many M proteins and has two well-characterized regions binding human plasma proteins: the hypervariable NH2-terminal region binds C4b-binding protein (C4BP), which inhib
The M protein family of molecules in the group A streptococcus comprises a number of cell surface proteins that interact with the immune system of the host. One of the proteins in this family is the IgA receptor Arp4, which has C repeats similar to those that characterize the known M proteins. The streptococcal strain expressing Arp4 also expresses a second immunoglobulin-binding protein, Mrp4, wh
