Shutters of My Mind
Author: Gil Francisco
Publisher: Xlibris Corporation
ISBN: 1477146628
Category : Poetry
Languages : en
Pages : 67
Book Description
"The Workbook" is exactly that, a workbook that could accompany the poetry book. Its purpose is to provide a series of cognitive exercises based on each piece featured in "Shutters of My Mind". Aeschylus said, "Memory is the mother of wisdom." Each drill is intended to exercise different aspects of the brain and its function. The drills include Word Scramble, Memorizing Unrelated Words, Matching, Short Term Recollection, Word Association, Rewriting and Memory Tips. Each of these exercises have been important in cognitive rehabilitation.

Category :
Languages : en
Pages : 788
Book Description
Since the inception of second edition of Prep Manual, a large body of knowledge has become available in various areas of medicine. The third edition has been substantially revised and updated incorporating the most recent knowledge in the subject. Almost every chapter has been revised or rewritten, and many new topics in each chapter have been added. It is hoped that this edition will fulfill all the needs of an undergraduate medical student. In addition, the basic concepts presented in this edition will be useful to the postgraduate students also. The third edition provides a new and comprehensive update of medicine.

Selection and Investigation of Sites for the Disposal of Radioactive Wastes in Hydraulically Induced Subsurface Fractures
Author: Ren Jen Sun
Publisher:
ISBN:
Category : Nuclear facilities
Languages : en
Pages : 100
Book Description
Injection of intermediate-level radioactive wastes (specific activity of less than 6 x 103γCi/mL, consisting mainly of radionuclides, such as strontium and cesium, having half-lives of less than 50 years) mixed with cement into a thick shale formation is a promising and feasible disposal method. Hydraulic fracturing provides openings in the shale to accommodate the wastes. Ion exchange and radionuclide-adsorption materials can be added to the grout during mixing to further increase the radionuclide-retaining capacity of the grout. After solidification of the grout, the injected wastes become an integral part of the shale formation, and therefore the wastes will remain at depth and in place as long as the injection zone is not subjected to erosion or dissolution. Problems concerning safety of the disposal method are (1) the potential for inducing vertical fractures, (2) phase separation during and after the injections, (3) the reliability of methods for determining the orientation of induced fractures, (4) the possibility of triggering earthquakes, and (5) radionuclides being leached and transported by ground water. In bedded shale, a difference between tensile strength normal to and that parallel to bedding planes favors the formation of fractures along bedding planes that are nearly horizontal. Even in areas where vertical stress is slightly greater than the horizontal stresses, nearly horizontal bedding-plane fractures can be hydraulically induced in shale at depths less than 1,000 meters. Test injections should be made during site evaluation to determine if horizontal bedding-plane fractures can be induced. The orientation of induced fractures can be indirectly monitored by recording injection pressures during injection time and by measuring the decay of water injections and the uplift of ground surface after the injections; however, it can be directly determined by gamma-ray logs made in observation wells before and after each injection, if the injected fluid or wastes contain enough gamma-ray emitting radionuclides. If waste grout is properly mixed, phase separation should be less than one percent of the total amount injected. The mobility of waste in the separated liquid is further decreased by the low permeability (less than 10−6 darcy) and the large ion-exchange and adsorption capacity of shale, which thus reduce the potential for contamination. Grout injections do not cause extensive increases in pore pressure within shale, and a disposal site should be located in a geologically stable and tectonically relaxed area, that is, an area lacking local active faults. Thus a disposal in shale in such areas can avoid the two necessary and essential conditions for triggering earthquakes by fluid injections, an increase in pore pressure and rock already stressed near its breaking strength. Waste injections are made in several stages at different levels through an injection well. After the first series of injections at the greatest depth, the well is plugged by cement at that depth. The second series of injections are made a suitable distance above the first. The repeated use of the injection well distributes the cost of constructing injection and monitoring wells over many injections, thereby making hydraulic fracturing and grout injection economically attractive as a method for the disposal of radioactive wastes. Theoretical considerations about inducing nearly horizontal beddingplane fractures in shale are discussed, as are field procedures for site selection, safety, and the monitoring and operation of radioactive waste disposal. Case histories are used as examples to demonstrate the application of the theory and techniques of field operations.
