Testing the disturbed zone around a rigid inclusion in salt

Deformational processes within a zone of rock surrounding excavations in salt result in alteration of the geophysical and hydrologic properties as compared to the undisturbed condition. The disturbed rock zone offers little resistance to fluid flow. It is hypothesized that rigid inclusions such as concrete seals will arrest and subsequently reverse the disturbance process and induce healing in the disturbed This experiment gathered in situ data that substantiates this hypothesis. A series of tests was conducted in a volume of rock surrounding concrete seals that were placed in a 1-m borehole approximately eight years ago. Fluid flow measurements, measurements of geophysical parameters of the surrounding rock and petrographic analyses on core samples were performed to characterize the rock. This paper presents the testing methodology and summarizes the data gathered from the field test program

Disseminating Effective Community Prevention Practices: Opportunities for Social Work Education.

In the United States about 17% of adolescents meet diagnostic criteria for mental, emotional, and behavioral disorders. Six million young people receive treatment services annually for mental, emotional, or behavioral problems. These problems affect 1 in 5 families and cost $247 million annually (O'Connell, Boat, & Warner, 2009). Some strategies for preventing mental, emotional, and behavioral disorders in young people have been developed, tested, and found to be effective in preventing the onset, persistence, and severity of psychological disorders, drug abuse, and delinquency. Unfortunately, tested and effective prevention policies, programs, and practices are not widely used (O'Connell, Boat, & Warner, 2009). This paper highlights recent advances in prevention science and describes some opportunities and challenges in advancing the use of science-based prevention in communities. The chapter concludes by exploring the potential role of social work education in developing a workforce ready to increase community access to effective prevention strategies
