The available mechanisms for the production of electrons in the three regions of the ionosphere are discussed with special reference to the question whether it is possible to account for the observed electron densities without supposing that the sun emits far more energy in the remote ultra-violet spectrum than would be emitted by a black body at 6000°. The contributions to electron densities made by metastable states of atoms and molecules are examined. It is concluded that the observed electron densities may be accounted for without requiring high solar energy in the ultra-violet if the effective recombination coefficient in the F 2 region is 10 -11 . The F 2 region is supposed formed by the ionization of atomic oxygen, and the E region by the ionization of molecular oxygen. The electrons forming the F 1 region are supposed to be provided by metastable N 2 or by NO.

The article presents the trajectory of two young entrepreneurs of the Brazilian audiovisual sector, seeking to present the main motivations to starting the business, difficulties faced during the process and profile of entrepreneurs. In order to achieve the proposed goal, we conducted in-depth semi-structured interviews with the young entrepreneurs over a period of six months. As main results it was verified that the main motivation to start the venture was the desire to develop projects independently and the opportunity to access government incentive policies that promote Brazilian film production. Among the main difficulties faced by the young entrepreneurs were the financial ones. They believe that a good entrepreneur is one who knows his goals, persists in reaching them, and overcomes adversities. The cases illustrates how a cultural entrepreneurship process is composed of a search for competences in both the artistic tools needed producing films as well as business startup and management.

This paper first compares with international incentive policies, reviews some relevant incentive measures in China. Meanwhile, introduce the content of the critical subsidy policies in detail, summarize its positive impact on PV industrial development, and analyze a few of representative unreasonable problem in the process of policy application. Finally, gains some inspirations for the worldwide application of PV industry in China as follow: promotes the on-grid of building integrated PV (BIPV) projects, formulates rational feed-in tariff linking to the distinction of solar energy resources of different areas, which can ensure the profitability of PV industry in its operation period.

Saturn's Rings

ABSTRACTA mission to rendezvous with the rings of Saturn is studied with regard to science rationale and instrumentation and engineering feasibility and design. Future detailedin situexploration of the rings of Saturn will require spacecraft systems with enormous propulsive capability. NASA is currently studying the critical technologies for just such a system, called Nuclear Electric Propulsion (NEP). Electric propulsion is the only technology which can effectively provide the required total impulse for this demanding mission. Furthermore, the power source must be nuclear because the solar energy reaching Saturn is only 1% of that at the Earth. An important aspect of this mission is the ability of the low thrust propulsion system to continuously boost the spacecraft above the ring plane as it spirals in toward Saturn, thus enabling scientific measurements of ring particles from only a few kilometers.
