numerical assessment of influence of confining stress on kaiser effect using distinct element method
nowadays acoustic emission (ae) testing based on the kaiser effect (ke) is increasingly used to estimate the in-situ stress in laboratories. in this work, this effect is assessed on cylindrical specimens in numerical simulations of the cyclic loadings including loading, unloading, and re-loading cycles using a 3d code called the particle flow code (pfc) based upon the distinct element method. t...
This research was conducted to study the effect of three nutrient solutions on potato (Solanum tuberosum) minituber production in hydroponic system under greenhouse conditions. The basic experimental design was factorial with randomized complete blocks with four replications. The first factor was nutrient solution at three levels (Hoagland and Snyder, Imma and Angel, Novella et al.) and the sec...
We provide an overview of the Kaiser Permanente Community Health Initiative--created in 2003 to promote obesity-prevention policy and environmental change in communities served by Kaiser Permanente-and describe the design for evaluating the initiative. The Initiative focuses on 3 ethnically diverse northern California communities that range in size from 37,000 to 52,000 residents. The evaluatio...
