Nevertheless, previous research have suggested that old women are less likely to receive adjuvant therapy for breast cancer. Because older women are under-represented in medical trials, their optimal treatment is not more developed. The researchers point to the need for further reducing mortality rates among women over 70 and ladies with ER-negative tumors.They also simulated more realistic, layered underground structures. The simulation showed that, the more layers a coastline provides, the more the saltwater and refreshing water mix. The blending causes convection – – similar to the currents that stir water in the open sea. Between your incoming saltwater and the inland refreshing drinking water, a pool of brackish drinking water forms. Further ocean level rise increases the mixing even more. Depending on how both of these factors interact, underground brackish water can extend 10 to 50 % inland than the saltwater on the surface further. According to the USA Geological Survey, about 50 percent the national country gets its normal water from groundwater.
