The development of photovoltaics as a serious means of producing renewable energy has accelerated greatly in the last ten years, with prices for silicon-based solar cell systems dropping dramatically in the last few years. The next great opportunity for photovoltaics following this competitiveness in prices will be to enhance the cell and panel efficiencies. It is quite generally seen that the mos
The purpose of this thesis is to augment our understanding of the Church of Yimrhane Kristos, and the Lasta period in which it was built, from the study of a variety of source materials. Due to the fact that the Lasta period suffers from the absence of adequate and reliable literary sources, this study largely depends on the elements of historic buildings as the basic data source. Using archaeomet
AbstractThe overall aim of this thesis was threefold; first, to explore resources associated with work-life balance (WLB), with a focus on the work and private lives of human service employees. Second, to develop a workplace health promotion (WHP) intervention with a WLB focus. Third, to explore the participants’ experiences of the developed WHP intervention done in the workplace. A mixed method a
This book is a philosophical exploration of the relationship between leadership and organization. Each chapter in the book sheds light on this relationship by exploring leadership with respect to a particular theme: charisma, authority, religion, language, authenticity, image and followership. These themes are linked to popular notions of leadership, such as transformational leadership, authentic
Animals, like humans, need to perceive their surroundings via their senses in order to make sensible behavioral decisions, reproduce successfully, and survive. Animals are equipped with audition, vision, thermosensation, hygrosensation, mechanosensation, magnetoception, gustation, and olfaction, which detects physical and chemical changes in their habitats. Among these senses, olfaction is likely
The rising trend in the prevalence of obesity, which is a major risk factor for a number of diseases notably diabetes and cardiovascular diseases, has become a major public health concern in many countries during the past decades. This development has also led to an increased cost burden on the public health care delivery system that has been documented in many studies. The standard approach taken
We have fabricated a device in which hollow nanowires (HNWs) lying on a glass surface are connected to microfluidic channels for the purpose of guiding DNA and to characterize the fluidic properties of our HNWs. The dimensions of our HNWs (inner diameter 10-80 nm, outer diameter 50-200 nm and length several μm) can be made on a scale much smaller than the size of a cell and on the same order of ma
Morphology represents a hitherto unexploited source of specificity in microfluidic particle separation and may serve as the basis for label-free particle fractionation. There is a wealth of morphological changes in blood cells due to a wide range of clinical conditions, diseases, medication and other factors. Also, blood-borne parasites differ in morphology from blood cells. We present the use of
We demonstrate that the detected emission intensity from YOYO-labeled DNA molecules confined in 180 nm deep Si/SiO2 nanofunnels changes significantly and not monotonically with the width of the funnel, an emission enhancement that is only detected for emitted light polarized parallel to the channel. We explain the enhancement effect as being due to optical phenomena in the channels. The enhancemen
