A Semiempirical model for Particle Deposition onto Facial Skin and Eyes. Role of Air Currents and Electric Fields

A semiempirical model has been developed for deposition velocity of particles on the forehead and eyes. It is based on published results of wind tunnel studies of deposition of 2-32 μm airborne particles onto the forehead and realistically-shaped eyes of a manikin. The effects of electric fields and particle charges were included in the model on a purely theoretical basis. The model was used to ca

Mechanisms of P fimbriae cell activation

Popular Abstract in Swedish De allra flesta mikrobiella infektioner börjar på slemhinnan och en gemensam nämnare för patogena mikroberna är deras förmåga att stimulera ett immunsvar på just den plats som de infekterat. De patogena bakteriernas kommer först i kontakt med epitelcellerna, som bildar kroppens barriär mot omgivningen. Interaktionen mellan patogener och dessa celler leder till ett inflaMicrobial attachment to host cells plays a central role in the induction of inflammatory responses and the production of the disease. Uropathogenic Gram negative bacteria carry surface lectins that specifically recognize oligosaccharide receptor epitopes expressed on glycolipids or glycoproteins. The resulting attachment may facilitate the action of other virulence factors, but may also activate t

Older People and the Adoption of Innovations: A study of the expectations on the use of social assistive robots and telehealthcare systems

Aims and objectives: The research presented investigates older people’s expectations of social assistive robots and telehealthcare systems. Methods: The empirical studies presented are based on fieldwork carried out before social assistive robots and a telehealthcare system were introduced into the domestic environment of older people. The research draws upon participatory design to explore older

Prospects of Observing the Decay B_c -> J/psi + pi and the Alignment Performance in the ATLAS Experiment

This thesis contains two main aspects of my research work towards physics in proton-proton collisions in the ATLAS experiment at the LHC. First, a Monte Carlo based analysis of the event yield and the mass shape for the ground state of the B_c meson in the hadronic decay channel B_c -> J/psi + pi was studied. The selection criteria have been optimised, the total number of signal events, and the si

Gender and Sexuality in Meret Oppenheim's Performance Art

What is woman’s role in the modernist avant-garde? Feminist art historians have long criticised the dominant masculinity of modernism. The problem, as I see it, is the unreflecting way in which history is written, and the way in which women are squeezed into theoretic models that really only affirm, and cater primarily for, men. The German-Swiss artist Meret Oppenheim (1913-1985) has been describe

An Emotional Model of Human-Environment Interaction

Previous models of environmental psychology have put the focus mainly on the cognitive processes, with each step in the process leading to the next in a rather static manner. This may be exemplified by some of the attitude theories developed over the last years (e.g. Ajzen and Fishbein, 1980; Stern, 2000). Among the few exceptions to the cognitive approach is Russell’s Circumplex model of emotiona
