Two different mathematical methods of implementing a detailed kinetic soot model have been employed in this work. The theoretical description of the soot modeling employed in this work is divided into three parts. Initially a detailed kinetic soot model is described from a chemistry and physics perspective. The soot model is then elaborated into mathematical form, starting with the formulation of
AIMS: To assess the Edinburgh Postnatal Depression Scale (EPDS), a self-administered questionnaire created to screen for symptoms of postpartum depression in the community, from an epidemiological and ethical perspective. Screening, as the practice of investigating apparently healthy individuals to detect unrecognised disease or its precursors, has interpretation problems and is complicated by del
The design and features of frequency-selective wallpaper created for attachment onto regular walls in order to filter out signals operating at 5 GHz while at the same time allowing the desired radio communication services to propagate through such walls are presented. An analysis of the characteristics of the radio channel evaluated in a typical indoor environment, when considering either regular
The cavitation phenomenon has today become a keystone for different areas of science and technology including various industrial processes and medicine. Recently increasing interest and much attention have been paid to study this phenomenon. The last two decades have witnessed the development of numerous devices for different important applications of considerable practical interest, and the rang
The Lake Poopo basin, located on the Bolivian Altiplano, is extremely vulnerable to environmental degradation. The basin displays extreme spatial and temporal variations of water resources and rapidly decreasing water quality due to anthropogenic and natural pollution. The region’s population lives in extreme poverty, and the authorities’ efforts to manage the water resources efficiently have been
Background The pattern of cancer in long-term survivors from childhood cancer has not been investigated comprehensively. Methods We obtained a cohort of 47 697 children and adolescents aged 0-19 years with cancer as defined by the country-wide cancer registries of Denmark, Finland, Iceland, Norway, and Sweden during 1943-2005. Cohort members were followed through age 79 years for subsequent primar
Conclusion Sentinel lymph node biopsies (SLNBs) can be performed safely and with reasonable accuracy in HNM patients. The outcome provides important prognostic information concerning DFS and further treatment. However, one must recognize that SLNB is a multidisciplinary procedure with a learning curve for all. Objectives To evaluate efficacy of performing SLNBs in a series of consecutive patients
This article aims at introducing to a wider circle a complementary research approach in user oriented work. Its most fundamental part is the use of technology as a tool for capturing the needs, wishes and dreams of a user. The incitement for us to start developing this method was an experience based, serious, questioning of conventional methods such as interviews, questionnaires, etc, and their c
The quasi-linear Maxwell equations describing electromagnetic wave propagation in nonlinear media permit several weak solutions, which may be discontinuous (shock waves). It is often conjectured that the solutions are unique if they satisfy an additional entropy condition. The entropy condition states that the energy contained in the electromagnetic fields is irreversibly dissipated to other energy
