- 4741: Could Gambling Save Science: Encouraging an Honest Consensus
- ... best funded at a local level, or even privately within a large university campus. A need for local appropriation of benefit argues against indirect funding methods, like prizes or idea futures, which cannot as easily control where the research they induce is performed. But such mechanisms might be well suited for science-for-its-own-sake philanthropy and for international funding of research, as such indirect methods can better avoid favoritism ...
- 4742: The Laser
- ... Lasers also are used to protect businesses by placing laser sensors in security systems. Military: Lasers play a very important role in the military. Unlike what is seen in science fiction movies where a laser gun could be used as a hand weapon, using today's technology lasers that powerful would have to be as big as the great pyramids in Egypt. Instead, we use them for range-finding devices or ...
- 4743: Fusion Energy
- ... the reactor structure would be much less than in a fission reactor and would be distributed through a greater thermal mass. In addition, because fusion is not a chain reaction, it cannot run out of control, and any tampering to the process would cause the plasma (the energy involved in the process) to extinguish itself. It would also be far more difficult to produce nuclear-weapons materials surreptitiously at a fusion ...
- 4744: The Black Hole
- ... is then referred to as a White Dwarf. If the star was to have a larger mass however, then it may possibly Supernova, meaning that the nuclear fusion within the star simply goes out of control causing the star to explode. After exploding a fraction of the star is usually left (if it has not turned into pure gas) and that fraction of the star is known as a neutron star ...
- 4745: Virtual Reality - What it is and How it Works
- ... a readable form for the computer. The machine calculates head/object position by the use of a lightweight, multiply-jointed arm. Sensors mounted on this arm measure the angles of the joints. The computer-based control unit uses these angles to compute position-orientation information so that the user can manipulate a virtual world. The joint angle transducers use conductive plastic potentiometers and ball bearings so that this machine is heavy ...
- 4746: Current Status of Malaria Vaccinology
- ... previously mentioned and as mentioned before this was done to evaluate its safety, immunogenicity and efficacy. This was done in a double blind manner all of the 199 volunteers either received R32Tox-A or a control vaccine (tetanus/diptheria toxiods (10 and 1 Lf units respectively) at 0, 8 and 16 weeks. Immunisation was performed in a malaria non-transmission area, after completion of which volunteers were deployed to an endemic ...
- 4747: Evolution
- ... emphasized the importance of mutation over selection in evolution. Early Mendelian geneticists believe that continuous variation (such features as body size) hardly factored in the formation of new species - perhaps nothing to do with genetic control. Inferences on the gradual divergence of populations diminished in wake of notions of significant mutations40. This gave rise to neo-Darwinian theory in the 1930's, what is called "modern synthesis" which encompasses paleontology, biogeography ...
- 4748: Andrew Jackson
- ... coins). This greatly restricted extensive lending by the state banks. The way it got this power was because it was the official depository for federal revenues, yet it was only remotely under the federal governments control (8). As stated in Britannica, congress approved of the recharter of the bank in 1832, but Jackson vetoed it on the grounds that it was a private monopoly that was immune to state taxes, and ...
- 4749: Into the Depths of A Black Hole
- ... is then referred to as a White Dwarf. If the star was to have a larger mass however, then it may possibly Supernova, meaning that the nuclear fusion within the star simply goes out of control causing the star to explode. After exploding a fraction of the star is usually left (if it has not turned into pure gas) and that fraction of the star is known as a neutron star ...
- 4750: Hail
- ... crystals, thus locking up any potential hailstorms. However, it has proved impractical because of the huge quantities of seeding agent needed to treat the clouds (Science and Invention Encyclopedia, 3118). The other method of hail control uses seeding agents to try to reduce the size of hailstones. The natural seeding process that goes on in a cloud can produce very large hailstones from the supercooled water droplets. Artificial seeding with enough ...
