The rate of increase in database size and response time requirements has outpaced advancements in processor and mass storage technology. One way to satisfy the increasing demand for processing power and I/O bandwidth in database applications is to have a number of processors, loosely or tightly coupled, serving database requests concurrently.

In this paper, we describe the architecture and features of DB2 Parallel Edition (PE). DB2 PE belongs to the IBM family of open DB2 client/server database products including DB2/6000, DB2/2, DB2 for HP-UX, and DB2 for the Solaris Operating Environment. DB2 PE employs a <i>shared nothing</i> architecture in which the database system consists of a set of(More)
BACKGROUND Paratuberculosis has a worldwide distribution and many countries have implemented control programs to prevent transmission among and within herds. For these programs to be efficient, knowledge of the risk factors involved in transmission is essential. OBJECTIVES Systematically review the scientific literature concerning risk factors associated(More)
Road traffic collisions (RTCs) are common precipitants of posttraumatic stress disorder (PTSD). Two preliminary studies suggest that cognitive-behavior therapy (CBT) is, on average, effective in treating this disorder, although the major patterns of treatment outcome remain to be identified. Such outcomes might include treatment response, partial response,(More)
Surveys of consumer satisfaction with psychiatric services are frequently included in program evaluations, ostensibly providing the patient's perspective. However, the consistently high levels of satisfaction reported, despite a wide variety of measures, suggest that these surveys may be of questionable validity. Recognizing that most surveys ask patients(More)
Mycobacterium avium subsp. paratuberculosis (MAP), the causative bacterium of Johne’s disease in dairy cattle, is widespread in the Canadian dairy industry and has significant economic and animal welfare implications. An understanding of the population dynamics of MAP can be used to identify introduction events, improve control efforts and target(More)
OBJECTIVE Neuroinflammation in utero may result in life-long neurological disabilities. The molecular mechanisms whereby microglia contribute to this response remain incompletely understood. METHODS Lipopolysaccharide (LPS) or saline were administered intravenously to non-anesthetized chronically instrumented near-term fetal sheep to model fetal(More)
Mycobacterium avium subsp. paratuberculosis (MAP) is the causative bacterium of Johne's disease (JD) in ruminants. The control of JD in the dairy industry is challenging, but can be improved with a better understanding of the diversity and distribution of MAP subtypes. Previously established molecular typing techniques used to differentiate MAP have not(More)
BACKGROUND The chronically instrumented fetal sheep is a widely used animal model to study fetal brain development in health and disease, but no methods exist yet to interrogate dedicated brain cell populations to identify their molecular and genomic phenotype. For example, the molecular mechanisms whereby microglia or astrocytes contribute to inflammation(More)
