This report details a survey of systems providing process or object migration. After an introduction to the topic a number of systems are covered in detail. Four chapters deal with systems providing migration over unmodi ed UNIX, those providing \classical" process migration and containing modi ed or new kernels, migration over modern microkernel based(More)
Prolonged use of glucocorticoids is associated with decreased bone formation, increased resorption and osteonecrosis, through direct and indirect effects on the activity and viability of bone effector cells, osteoblasts and osteoclasts, and osteocytes. This study has investigated molecular pathways implicated in Dexamethasone-induced apoptosis of(More)
Migration is the movement of an active entity from one machine to another during execution. Such migration may be used for dynamic load balancing purposes with the aim of gaining increased performance from a group of processors than may be gained by schemes simply allocating processes to processors at run time. Schemes providing object migration also offer(More)
Hyperkalemia, a condition in which serum potassium ions (K+) exceed 5.0 mmol/L, is a common electrolyte disorder associated with substantial morbidity. Current methods of managing hyperkalemia, including organic polymer resins such as sodium polystyrene sulfonate (SPS), are poorly tolerated and/or not effective. Sodium zirconium cyclosilicate (ZS-9) is(More)
The progress of development of stem-base pathogens in crops of second winter wheat was plotted in nine experiments in three years. The amount of each pathogen present was determined by quantitative PCR. Where Tapesia yallundae was present in quantifiable amounts, it usually developed earlier than the other eyespot pathogen, T. acuformis. Both species were(More)
The term "tipping point" has become increasingly popular in scientific and media usage to refer to the world in which we live, to describe the probable effects of the processes arising from the consequences of the ways we live with and transform the world, to describe our relationships with the environment, and the effects of our actions. Through this shift(More)
Using the Xiphophorus fish melanoma model, we show a strong male bias for sunlight-induced malignant melanoma, consistent with that seen in the human population. To examine underlying factors, we exposed adult X. couchianus fish to a single, sublethal dose of UVB and measured circulating sex steroid hormones and expression of associated hormone receptor(More)
