Collezione Per Genova
1958-1978: 20 anni di sperimentazioni spaziali in Occidente La collezione copre il ventennio 1958-1978 che è stato particolarmente importante nella storia della esplorazio- ne spaziale, in quanto ha posto le basi delle conoscenze tecnico-scientifiche necessarie per andare nello spa- zio in sicurezza e per imparare ad utilizzare le grandi potenzialità offerte dallo spazio per varie esigenze civili e militari. Nel clima di guerra fredda, lo spazio è stato fin dai primi tempi, utilizzato dagli Americani per tenere sotto con- trollo l’avversario e le sue dotazioni militari, in risposta ad analoghe misure adottate dai Sovietici. Per preparare le missioni umane nello spazio, era indispensabile raccogliere dati e conoscenze sull’alta atmo- sfera e sulle radiazioni che si incontrano nello spazio che circonda la Terra. Dopo la sfida lanciata da Kennedy, gli Americani dovettero anche prepararsi allo sbarco dell’uomo sulla Luna ed intensificarono gli sforzi per conoscere l’ambiente lunare. Fin dai primi anni, le sonde automatiche fecero compiere progressi giganteschi alla conoscenza del sistema solare. Ben presto si imparò ad utilizzare i satelliti per la comunicazione intercontinentale e il supporto alla navigazio- ne, per le previsioni meteorologiche, per l’osservazione della Terra. La Collezione testimonia anche i primi tentativi delle nuove “potenze spaziali” che si avvicinano al nuovo mon- do dei satelliti, che inizialmente erano monopolio delle due Superpotenze URSS e USA. L’Italia, con San Mar- co, diventò il terzo Paese al mondo a lanciare un proprio satellite e allestì a Malindi la prima base equatoriale, che fu largamente utilizzata dalla NASA. Alla fine degli anni ’60 anche l’Europa entrò attivamente nell’arena spaziale, lanciando i propri satelliti scientifici e di telecomunicazione dalla propria base equatoriale di Kourou. -

INTRODUCTION This Study of Reentry Vehicle (RV)
INTRODUCTION This study of Reentry Vehicle (RV) systems and their associated operations was conducted for the Department of Transportation/Office of Commercial Space Transportation. The purpose of the study was to investigate and present an overview of reentry vehicle systems and to identify differences in mission requirements and operations. This includes reentry vehicle system background, system design considerations, description of past/present/future reentry systems, and hazards associated with reentry vehicles that attain orbit, reenter, and are recovered. A general literature search that included the OCST data base, NASA, Air Force, and other technical libraries and personal contact with various government or private industry organizations knowledgeable in reentry system vehicles was performed. A reference page is provided at the end of this report. A history of early manned reentry vehicle launches is shown in Appendix I. A listing of some of the agencies and companies found to be most knowledgeable in the reentry vehicle area is provided in Appendix II. The following sections provide more detailed information on reentry system vehicles. A. Background - The development of reentry vehicles began in the late 1950's due to the need for Department of Defense and Central Intelligence Agency photo reconnaissance of Soviet ICBM sites. NASA has also been involved in the use of reentry vehicles since the early 1960's, including manned space programs Mercury, Gemini and Apollo. The following sections describe the evolution of reentry system development in the United States and foreign countries: 1. Discoverer1 - The Discoverer program was of major importance because it provided a vehicle for testing orbital maneuvering capability and reentry techniques and it played a large role in enabling the first United States manned space flights to be conducted in Project Mercury. -

Argentina conto con soñadores e idealistas de las posibilidades del progreso y evolución científico- cultural que anunciaba la naciente Astronáutica. Ya, en 1933 en la entonces revista “Boletín del Centro Naval”, el ingeniero electricista inspector Juan Frikert publicaba en varios de sus números un extenso trabajo físico-matemático con el título de “El Mito de la Navegación Cósmica”, y agregaba el subtitulo Estudio analítico sobre la posibilidad de atravesar la zona de gravitación terrestre”. Inicia su trabajo diciendo : “El propósito de abandonar a la madre tierra para visitar nuestros vecinos cósmicos hasta hace pocos años solo vivía en la mente de algunos autores de novelas fantásticas ”. El nivel de este trabajo y la seriedad científica del mismo es del máximo nivel, o superior al de los grandes pioneros europeos de la época. Luego a finales de los años cuarenta, nacería la Asociación Argentina Interplanetaria del Ing. Teófilo M. Tabanera y años después, su primer desprendimiento IDEA, el Instituto de Experimentaciones Astronáuticas, autor en los cincuenta del “Martin Fierro”, el primer cohete civil argentino. A inicios de la década de los sesenta se produce la “revolución juvenil” del ICTE el Instituto Civil de Tecnología Espacial y sus más de cien lanzamientos experimentales. -

CASE NO. 201 0-001 16 ATTORNEY GENERAL'S INITIAL REQUEST FOR INFORMATION DATED MAY 24,2010 3. Please explain in detail any major changes in accounting treatment for O&M expenses, retirements, replacements and removal costs instituted by the Company since 2003. Response: The most significant change resulted from changing our capitalization threshold from $500 to $2,000 in 2004. For SEC reporting purposes, the Company reclassified cost of removal out of accumulated depreciation into regulatory liabilities, adopted SFAS 143 and adopted FIN 47. None of these changes have any impact on this rate case, as Delta has excluded all of these balances in the pro forma numbers. -

Parks,1 Jane R. Stout,1,2 Scott B. Shepard,1,3 Kristin M. Klueg,4 Ana A. Dos Santos,5 Todd R. Parody,6 Martina Vaskova7 and Marc A. T. Muskavitch8 Biology Department, Boston College, Chestnut Hill, Massachusetts 02467 Manuscript received June 19, 2006 Accepted for publication September 18, 2006 ABSTRACT The transmembrane proteins Delta and Notch act as ligand and receptor in a conserved signaling pathway required for a variety of cell fate specification events in many organisms. Binding of Delta to Notch results in a proteolytic cascade that releases the Notch intracellular domain, allowing it to participate in transcriptional activation in the nucleus. Recent research has implicated the endocytic and ubiquitylation machinery as essential components of Delta–Notch signaling. Our analysis of chimeric and missense Delta variants has delineated a number of structural requirements for Delta trafficking, receptor binding, and signaling. We find that while the Delta N-terminal domain is necessary and sufficient for binding to Notch, the integrity of the epidermal-growth-factor-like repeat (ELR) 2 is also required for Notch binding. Screening of 117 Delta mutant lines for proteins that exhibit aberrant subcellular trafficking has led to the identification of 18 Delta alleles (DlTD alleles) that encode ‘‘trafficking-defective’’ Delta proteins. We find, unexpectedly, that many DlTD alleles contain missense mutations in ELRs within the Delta extracellular domain. Finally, we find that two DlTD alleles contain lysine missense mutations within the Delta intracellular domain (DeltaICD) that may identify residues important for DeltaICD mono-ubiquitylation and subsequent Delta endocytosis and signaling. -

It details the steps in the evolution of the vehicle family, noting how the evolving lift capability compares with the evolving lift requirements. A system description is given for each vehicle. The cost of each development stage is described. Also discussed are demonstration programs, the merits of the SSME vs. an expendable rocket engine (RS-68), and finally, the next steps needed to refine this concept.

I. Introduction n response to President Bush’s Space Exploration Vision, both NASA and the aerospace industry have proposed Ivarious exploration architectures. The launch vehicles are a key element of these architectures. While some architectures are geared to exploit existing launch vehicles, many require the development of new vehicles to support manned flights and heavy lift. Three principle approaches are the “clean sheet” vehicle, further evolving the evolved expendable vehicles (Atlas V, Delta IV), or a new vehicle based on existing Shuttle elements and technology. -
Now That It Looks Like We Will Have Additional Project Reports That Will
NEMI 2006 iNEMI Optoelectronic Substrates Project Report Optoelectronic Substrates Project Report 1 November 1, 2006 The 2002 iNEMI Roadmap identified the potential for an optoelectronics interconnection system to replace existing copper interconnect systems for high bandwidth applications. The unresolved issues were, what bandwidth will be required for various applications, and at what bandwidth will the cost of optoelectronics interconnect systems become cost effective. The optoelectronic system would have an optoelectronics substrate on which to mount optoelectronic components including devices and connectors. An Optoelectronics Substrates Project group was formed in 2003 to address this emerging issue. Many iNEMI member companies were interested in participating. This project was the result of these discussions. The group has served as an excellent forum for interaction among members of the current progress, future direction, and implications of optoelectronic developments within the industry. Now four years later, it is not as clear as to when optoelectronic substrates will be needed by industry. Firms are continuing to improve the performance of copper systems, and wireless systems are rapidly expanding. This report serves to document the accomplishments of this project over the past four years. If future roadmaps identify the impending need of optoelectronic substrates, it is hoped that this report can serve as a starting point for future projects.

Introduction A regular element of the debate about nuclear weapons and arms control is the presentation of data on the relative levels of US and USSR strategic forces, often in the form of tables or charts. Frequently, the data presented is unclear in terms of where it came from or what assumptions were used to construct it. Some tables present current "total" forces, others "on-line" forces, "alert" forces, "generated alert" forces, or "SALT accountable" forces. Each is important and more usable if detail about the sources and assumptions is provided.
