We report on the characterization of single-photon avalanche diodes (SPADs) fabricated in standard 140-nm silicon on insulator (SOI) complementary metal-oxide-semiconductor (CMOS) technology. As a methodology for SPAD optimization, a test structure array, called SPAD farm, was realized with several junctions, guard-ring structures, dimensions, etc. In this paper, characterization results of the...
Farm ponds, reservoirs and in-stream weirs exist in most lowland UK river catchments often dominate over natural features such as lakes, wetlands, floodplains debris dams. Artificial structures have served multiple purposes, including provision of power for historic flour milling iron ore crushing water medieval fishponds, canals, crop irrigation potable supply. Although unintentional, they can...
Antimicrobial resistant (AMR) bacteria are increasing threats for human and veterinary medicine. Faecal Escherichia coli (E. coli) from preweaned dairy calves is often resistant to multiple antimicrobials and calves may therefore serve as reservoirs for these bacteria and their resistance genes. This thesis investigated the prevalence, risk factors, and spread of resistant E. coli on Swedish da...
It has been suggested that the emergence of livestock associated MRSA in swine may be a consequence of feeding antibiotics and/or zinc to control swine diseases or promote growth. However, the dynamics and health implications of interspecies transmission of MRSA from pigs to humans is still incompletely understood. To address these questions, better understanding is required of the broader ecol...
Recent research on the impact of institutions su¤ers from historical, theoretical, and methodological problems. The historical issue is whether the initially poorer countries became wealthier, as Acemoglou, Johnson, and Robinson (2002) would have us believe. The theoretical question is whether the institutions that should matter are those that protect property rights or those that coordindate i...

Genetic variation in an infectious disease pathogen can be driven by ecological niche dissimilarities arising from different host species and different geographical locations. Whole genome sequencing was used to compare E. coli O157 isolates from host reservoirs (cattle and sheep) from Scotland and to compare genetic variation of isolates (human, animal, environmental/food) obtained from Scotla...
q fever is a worldwide zoonosis with many acute and chronic manifestations caused by the pathogen coxiella burnetii . farm animals and pets are the main reservoirs of infection, and transmission to human beings is mainly accomplished through inhalation of contaminated aerosols. persons at greatest risk are those in contact with farm animals and include farmers, abattoir workers, and veterinaria...
