Sommario/riassunto |

Ensuring safe and plentiful supplies of potable water (both now and for future generations) and developing sustainable treatment processes for wastewater are among the world's greatest engineering challenges. However, sustainability requires investment of money, time and knowledge. Some parts of the world are already working towards this goal but many nations have neither the political will nor the resources to tackle even basic provision and sanitation. Combining theory and practice from the developing and developed worlds with high- and low-tech, high- and low-cost solutions, this book di |

Sommario/riassunto |

Nowadays, 25% of materials used are metals, and this ratio is not expected to decrease, as metals are indispensable for many applications due to their high resistance to temperature. The only handicap of metals is their relatively higher density with respect to composites. Lightening of metallic structures is possible in three ways: (i) employing low density metals, (ii) developing new ones, and (iii) increasing the yield strength of existing high-density metals. The Laboratory of Excellence of the Lorraine University in France, called 'Design of Alloy Metals for Low-Mass Structures', is working to lighten metal via metallurgical means. Two leading research laboratories compose this Laboratory of Excellence within the Lorraine University: the Laboratory of Microstructure Studies and Mechanics of Materials (LEM3), based in Metz, and the Jean Lamour Institute (IJL), located in Nancy. In this Special Issue, they report on some of their major progress in the different fields of metallurgy and mechanics of metallic materials. There are articles in the three major fields of metallurgy: physical, chemical, and mechanical metallurgy. All scales are covered, from atomistic studies to real-scale metallic structures. |

Sommario/riassunto |

"For both diplomatic and national security reasons, security cooperation continues to be important for the United States. The needs and existing capabilities of various nations differ, however, as will results. In previous research, RAND identified a series of factors that correlate with the success of building partner capacity (BPC) efforts. Some of these are under U.S. control, and some are inherent in the partner nation or under its control. Strategic imperatives sometimes compel the United States to work with PNs that lack favorable characteristics but with which the United States needs to conduct BPC anyway. This report explores what the United States can do, when conducting BPC in challenging contexts, to maximize prospects for success. The authors |

address this question using the logic model outlined in a companion report and examining a series of case studies, looking explicitly at the challenges that can interfere with BPC. Some of the challenges stemmed from U.S. shortcomings, such as policy or funding issues; others from the partner's side, including issues with practices, personalities, baseline capacity, and lack of willingness; still others from disagreements among various stakeholders over objectives and approaches. Among the factors correlated with success in overcoming these challenges were consistency of funding and implementation, shared security interests, and matching objectives with the partner nation's ability to absorb and sustain capabilities."--Back cover. |
