Report presenting an investigation to determine the lift, drag, and pitching-moment characteristics of the NACA 0010 and 0010-64 airfoil sections at Mach numbers up to 0.91 and for a range of Reynolds numbers.

Report presenting an investigation to determine the possibility of delaying at moderate or large lift coefficients the onset of the abrupt supercritical drag rise of an airfoil section by the use of camber. Results indicated that the addition of camber to the NACA 0010 airfoil leads to significant improvements in the drag characteristics at moderately supercritical speeds .

This report describes the characteristics of the Great Lakes, the interests they support, and possible threats to lake levels.

U.S. aid to the Palestinians has fluctuated considerably over the past three years, largely due to Hamas's changing role within the Palestinian Authority (PA). Since Hamas's forcible takeover of the Gaza Strip in June 2007, the U.S. has dramatically boosted aid levels to bolster the PA and President Mahmoud Abbas vis-à-vis Hamas. Because of congressional concerns that, among other things, U.S. funds might be diverted to Palestinian terrorist groups, much of this assistance is subject to legislative restrictions. Experts advise that PA stability hinges on, now more than ever, improved security, economic development, Israeli cooperation, and the continuation of high levels of foreign assistance.

In response to the terrorist attacks against the United States on September 11, 2001, a number of countries and organizations pledged various forms of support to the United States in its campaign against the Al Qaeda network and the Taliban in Afghanistan. This report summarizes support for the U.S. war against terrorism from open source material.

There appears to be a growing international consensus to adopt progressively strict economic sanctions against Iran to try to compel it to compromise on its further nuclear development. The U.S. view - increasingly shared by major allies-is that sanctions should target Iran's energy sector, which provides about 80% of government revenues, and try to isolate Iran from the international financial system. U.S. efforts to curb international energy investment in Iran's energy sector began in 1996 with the Iran Sanctions Act (ISA). ISA has been expanded significantly in 2010. This report discusses said expansions, provides background on the ISA, and explores how this Act has affected

This report focuses on enforcement of federal environmental pollution control requirements under the Clean Air Act (CAA); the Clean Water Act (CWA); the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund); and other statutes for which EPA is the primary federal implementing agency.1 The report provides a brief synopsis of the statutory framework that serves as the basis for pollution control enforcement, including an overview of the key players responsible for correcting violations and maintaining compliance. Implementation and enforcement of pollution control laws are interdependent and carried out by a wide range of actors including federal, state, tribal, and local governments; the regulated entities themselves; the courts; interest groups; and the general public.

The 618-11 (Wye or 318-11) burial ground received transuranic (TRTJ) and mixed fission solid waste from March 9, 1962, through October 2, 1962. It was then closed for 11 months so additional burial facilities could be added. The burial ground was reopened on September 16, 1963, and continued operating until it was closed permanently on December 31, 1967. The burial ground received wastes from all of the 300 Area radioactive material handling facilities. The purpose of this document is to characterize the 618-11 solid waste burial ground by describing the site, burial practices, the disposed wastes, and the waste generating facilities. This document provides information showing that kilogram quantities of plutonium were disposed to the drum storage units and caissons, making them transuranic (TRU). Also, kilogram quantities of plutonium and other TRU wastes were disposed to the three trenches, which were previously thought to contain non-TRU wastes. The site burial facilities (trenches, caissons, and drum storage units) should be classified as TRU and the site plutonium inventory maintained at five kilograms. Other fissile wastes were also disposed to the site. Additionally, thousands of curies of mixed fission products were also disposed to the trenches, caissons, and drum storage units. Most …
