Large experiments

The matrix can be taken away by HN03 except at the ends of the wire, to allow easy soldering. Below IK, the electrical contact can be done also by squeezing the wires to be connected inside a thin A1 tube (see, for example, Section 12.4). For low-level signals, shielded twisted pairs or cryogenic coaxial cables are used. When thousands of wires are necessary, as in large experiments, Kapton strips with deposited conductors [3] or woven wires [4] are used. 

The large experience with neoadjuvant chemotherapy (also called induction, primary, or preoperative chemotherapy) in patients with LABC allows us to derive the following conclusions ... 

Several large experiments are planned which should demonstrate pellet gain in excess of unity, i.e. scientific feasibility. The experiments with laser drivers are under development e.g. at Lawrence Livermore Laboratory and at Los Alamos Scientific Laboratory (USA)20 those with relativistic electron beams at Sandia Laboratory, Albuquerque (USA)21 and at Kurchatov Institute (USSR). They are scheduled to start operation in the early 1980 s. 

It is a sin to perform an experiment that is either too small or too large. Experiments that are excessively large are obviously a waste of resources. An answer could have been arrived at with less expenditure of time, effort and cash. If animals or humans were the subjects of the experiment, then there is also the ethical issue of unnecessary inconvenience or suffering. Experiments that are too small are perhaps even worse. If numbers are inadequate then the statistical... 

We can avoid sticking problems by keeping the particles cool and dry. However, the particles must be large enough, both in the small and the large experiments. 

Unfortunately, our understanding of the physics and chemistry of salt formation is not yet at a stage where we can predict a priori the physicochemical properties of a proposed salt. A particular problem in this regard is the formation of a range of salt polymorphs and/or solvates. While qualitative/semiempi-rical guidelines have been developed, the selection process is still largely experiment based. It is to be hoped that developments in computational methods will soon lead to the more accurate prediction of bio-pharmaceutically relevant solid-state properties that will ultimately simplify the task of appropriate salt selection. 

The ability of nitroglycerine to burn is now being utilized (on a large experi mental scale) to inipiovc the burning of ethanol being used as a fuel for ca engines in Brasil.. A small proportion (ca. 3%) is added to ethanol for this pu pose, so far with a positive result (108). 

To return to our discussion of experiments, a good experiment is one which may reasonably be expected to be salient. Obviously, other things being equal, a large experiment is better than a small one, and one which is too small is unlikely to be salient. Hence the belief has arisen that the major function of the statistician in designing an experiment is to use his theories to determine the sample size. In fact, sample size is only one aspect of the problem and its importance has been overrated. 

Describe a very large experiment. How can this experimental plan be modified to cost less to conduct ... 

Development of an automatic measurement system is practical, if the same kind of measurements are made frequently. Also, the type of experiment affects the dennand to develop an automatic system. Very long or very fast experiments are often impossible to control and follow manually, b ause a human operator cannot work long periods without pauses and in rapid experiments the sampling rate can exceed that possible by hand. In large experiments the number of controlled and measured quantities restrict operators ability to follow every detail. These cases require automation. 

Large experience has been already gained with sodium cooled fast reactor operation. The use of sodium as a coolant poses fire danger in case of its leakage and interaction with air or water. Operating experience testifies the possibility of coping with the mentioned problem, but the quest for excellence calls for future improvement in LMFRs technology. 

France, Japan and the Russian Federation presented the status on sodium cooled fast reactor experience preservation made in these coimtries. The reports underlined these countries large experience with design, construction and operation of sodium cooled fast reactors. The discussions underlined the importance of the IAEA support for knowledge preservation of fast reactor experience. 

Large experience has been gained in reactor operation with failed fuel elements, including fuel elements with deliberately perforated cladding.
