Potash Salts from Texas-New Mexico Polyhalite Deposits: Commercial Possibilities, Proposed Technology, and Pertinent Salt-Solution Equilibria (open access)

Potash Salts from Texas-New Mexico Polyhalite Deposits: Commercial Possibilities, Proposed Technology, and Pertinent Salt-Solution Equilibria

From Introduction: "Figure 1 shows the location of sources that have been either exploited or seriously considered at one time or another, super-imposed upon a map indicating by small letters the order of consumption of K2O in the leading States; the amount used in these States, together with the percentage of the total consumption of potash used as fertilizer in the United States in 1939, is given in table 1. Figure 2 shows the domestic production and total consumption of potassium salts, in terms of tons of K2O, with the value per unit at the plants, for each year since 1913. Considered together, these two figures tell a significant story."

Navy Nuclear Aircraft Carrier (CVN) Homeporting at Mayport: Background and Issues for Congress (open access)

Navy Nuclear Aircraft Carrier (CVN) Homeporting at Mayport: Background and Issues for Congress

On January 14, 2009, the Navy announced that it wants to transfer one of its nuclear-powered aircraft carriers (CVNs) to the Navy home port at Mayport, FL, known formally as Naval Station (NAVSTA) Mayport. The Navy's proposed FY2010 budget requests $46.3 million in Military Construction (MilCon) funding for channel dredging at Mayport. The Navy states that a key reason it wants to transfer a CVN to Mayport is to hedge against the risk of a catastrophic event that could damage the Navy's CVN homeporting facilities at Norfolk, VA, and nearby Newport News, VA. This report discusses potential questions for Congress to consider related to budget appropriations for such a transfer, the potential negative economic effects that a CVN transfer would have on the local homeport, and the other general questions regarding the Navy.
