This fact sheet tracks the current heads of government in Central and South America, Mexico, and the Caribbean. It provides the dates of the last and next elections for the head of government and the national independence date for each country.

New classes of quasi-helically symmetric stellarators with aspect ratios ≤ 10 have been found which are stable to the perturbation of magnetohydrodynamic modes at plasma pressures of practical interest. These configurations have large rotational transform and good quality of flux surfaces. Characteristics of some selected examples are discussed in detail. The feasibility of using modular coils for these stellarators has been investigated. It is shown that practical designs for modular coils can be achieved.

As the global need for energy increases, scientists and engineers have found a possible solution by using hydrogen to power our world. Although hydrogen can be combusted as a fuel, it is considered an energy carrier for use in fuel cells wherein it is consumed (oxidized) without the production of greenhouse gases and produces electrical energy with high efficiency. Chemical storage of hydrogen involves release of hydrogen in a controlled manner from materials in which the hydrogen is covalently bound. Sodium borohydride and aminoborane are two materials given consideration as chemical hydrogen storage materials by the US Department of Energy. A very significant barrier to adoption of these materials as hydrogen carriers is their regeneration from 'spent fuel,' i.e., the material remaining after discharge of hydrogen. The U.S. Department of Energy (DOE) formed a Center of Excellence for Chemical Hydrogen Storage, and this work stems from that project. The DOE has identified boron hydrides as being the main compounds of interest as hydrogen storage materials. The various boron hydrides are then oxidized to release their hydrogen, thereby forming a 'spent fuel' in the form of a lower boron hydride or even a boron oxide. The ultimate goal of this project …

This report tracks the process by which Congress provides the funding for U.S. assessed contributions to the regular budgets of the United Nations, its agencies, and U.N. peacekeeping operation accounts, as well as for U.S. voluntary contributions to U.N. system programs and funds. It includes information on the President's request and the congressional response, as well as congressional initiatives during this legislative process. Basic information is provided to help the reader understand this process.

This report reviews and discusses President Obama's Open Government Initiative and the Open Government Directive. The report then analyzes both agency response to the OGI and the OGD, and examines whether the OGD's requirements can meet the stated goals of the Administration. The report discusses the three central tenets of the Administration's OGD--transparency, public participation, and collaboration--and analyzes each one individually to determine whether agencies are meeting these requirements and whether the requirements may improve the effectiveness of the federal government.
