The evolution of the C(ls) shake-up, s.u., satellite structure upon doping with sodium is shown in Hg. 6. The spectrum for the neutral molecule is shown at the bottom and increasing doping upwards. The solid lines follow a three point smoth of the data points. The s.u. structure appears as very weak features on the high binding energy side of the C(ls) main peak. The main peak, indicated by the dashed line, is omitted in order to emphasize the weak s.u. signal. The s.u. 

Not all assessments of the present state of climate theory are optimistic. An extensive discussion on the global warming paradigm was organized at the conference in London on January 27, 2005 at the Hadley Center where various points of view were considered. Some climate scientists insist, unlike others, that human activity and climate change are directly linked. Professor Fred Singer, former director of the U.S. Weather Satellite Service, told the BBC ... 

First, satellite structure on the high binding energy side of, for example, an XPS core-level line (or peak ) corresponds to so-called shake-up (referred to below as s.u. ) and shake-ofF2S-29 effects, the former of which is illustrated, by M+, in Fig. 3.1. Shake-off is just shake-up to the continuum rather than to an unoccupied molecular state. Considerations of (1) are important in comparisons with the results of model calculations while (2) is of use as an indication of the electronic transitions in the molecules under study, an example of which is found in studies of the early stages of interface formation, i.e., the interactions of reactive metal atoms with conjugated polymer surfaces. Since use will be made of these effects in subsequent chapters, they are outlined briefly below. 

Sputnik was launched by the Soviet Union in 1957, and in 1962, NASA launched Telstar, the first U.S. communications satellite. Communication satellites from many countries currendy support a wide variety of communications.

The Montreal Protocol of July 1987 resulted in an international treaty in which the industrialized nations agreed to halt the production of most ozone-destroying chlorofluorocarbons by the year 2000. This deadline was hastily changed to 1996, in February 1992, after a U.S. National Aeronautics and Space Administration (NASA) satellite and high-altitude sampling aircraft found levels of chlorine monoxide over North America that were 5i % greater than that measured over Antarctica.

An example of propellant tailoring is the fuel used to launch the first U. S. satellite into orbit. The original fuel for the launch vehicle was ethyl alcohol. MAF-4 (also known as hydyne or U-DETA), a mixture of 60% UDMH and 40% diethylenetriamine (DETA), was formulated to simulate the physical properties of C2H5OH but provide the increased propellant performance (using liquid oxyen as the oxidizer) requirements of the mission. 

Singer has received numerous awards for his research, including a Special Commendation from the White House for achievements in artificial earth satellites, a U.S. Department of Commerce Gold Medal Award, and the first Science Medal from the British Interplanetary Society. He has served on state and federal advisory panels, including five years as vice chairman of the National Advisory Committee on Oceans and Atmospheres. He frequently testifies before Congress. 

The most interesting feature of the decomposition flames is their analogy to flames of the solid monopropellants. In fact, many of these substances, which are ordinarily liquids, may support a flame directly from the liquid phase without auxiliary vaporization of the liquid. In this case, the flame supplies the necessary heat of vaporization or decomposition in exact analogy to the solid propellant flame.8 The principal usefulness of a decomposition flame is found in the simplicity of design and control of a rocket powered by such a flame, even though more powerful fuels are readily available. A recent example, which has been featured in the news, is the hydrogen peroxide attitude-control rocket used in the artificial earth satellites of the U.S.A. 

As Mitra (2004) pointed out, the Indian oceanic experiment (INDOEX) was the first complex problem-oriented observational international program aimed mainly at studies of the aerosol-induced radiative and climatic forcing of regional and global climate that take respective feedbacks into account. The preliminary stage of the accomplishment of INDOEX began in 1996-1997, and the basic part of complex observations was accomplished in 1998-1999 with the participation of specialists from different countries (India, U.S.A., Western Europe, Mauritius, and the Maldives). The obtained results were based on the use of surface, ship, aircraft, and satellite observational means. 

International Arctic Ozone Study, which runs campaigns in winter every year. NASA researchers and many scientists from the U.S.A., the E.U., Canada, Iceland, Japan, Norway, Poland, Russia, and Switzerland work together in winter to measure ozone and other atmospheric gases. The scientists use aircraft, large and small balloons, ground-based instruments, and satellites. 

Launchings of satellites CloudSat (Stephens et al., 2002) and CALIPSO (Vaughan et al., 2004) to obtain data on aerosol and cloud cover characteristics. CloudSat was a joint initiative between the U.S.A. and Canada, and CALIPSO between the U.S.A. and France.
