We Have Done Better

ANSWER I think that elearly it is possible that there is no neurotoxieity in humans. I think all of us would like for this to be the ease. And maybe it is the ease. We have talked about this a lot with fenfluramine, and we have done studies with paraehloroamphetamine in whieh we have given it orally to rats at relatively low doses, but still anoreetie doses, over 90 days. We have seen depletion of serotonin, but that was fully reversible depletion. It eame baek when the drug was stopped. I think there may be no neurotoxieity at the oral doses used in humans. I think that would be great if that is the ease. That would explain why there is no depression or other kinds of symptoms. But I don t feel comfortable about relying on the laek of reporting of depression as real evidence that there is no neurotoxieity. We simply need to have better data on that. 

Since the beginning of the environmental movement in the 1960s many people have asked repeatedly if we better off environmentally today and, if so, can we do even more than we have done In some respects we see a bad side. The chemical industry still has a large amount of toxic chemical emissions. Pollution control is getting more expensive. On the brighter side. 

The elimination of thorium is of prime importance to Rhone-Poulenc and we have done a considerable amount of research to find a solution to this problem. Actually, the thorium level of our rare earth product is comparable to, if not better than, that of other products available on the market. Most of the time thorium is not even detectable. 

In principle one should not, of course, use a macroscopic concept like dielectric constant in a complex of molecular dimensions. But in the theory of electrolyte solutions this has been done for some time and will continue to be done until we have something better and more convenient. 

But if we change the initial condition (xa2(0), x/ri( - )) of tank 2 to become (1,0) and use (xa3(0), a eafO)) = (0,1) for tank 3 in Figure 6.35, then the output of B at the exit of tank 3 becomes rather small at around 19% of the useful component B. In fact we could have done better for these initial conditions by reducing the three CSTR... 

On the other hand, the problem of the planar lattice seems to be at the limit of calculation by mechanical means. First of all, we.tried, as we have done for the chain, to calculate the asymptotic values and their fluctuations by a process imitating that of crystallization. We believe now that it is better to separate them and to determine successively ... 

Nobody is ever too old to learn, especially on such a complex matter as an integration of two companies. Dimensions where we could have done better and to which we would clearly pay particular attention next time are ... 

As we emphasized towards the end of Sec.II, OAI is an IBA but OAIT is not. Nevertheless, Arima et. al. presented [12] the relatively better OAIT result as an evidence to justify IBA. However, this presentation is again very misleading. The OAI results should have been presented as IBA, as we have done so in our Fig.l. 

Observations are taken from Jones and Mott, Proc. Roy. Soc., 162, 49 (1937). Calculations in that paper assume different numbers of electrons per atom, instead of one per atom as we have done, and secure somewhat better agreement with experiment. Specific heats are tabulated in calories per mole. 

From the time of the second edition published in 2001 until now, much progress has been achieved. Several techniques have been improved, others have almost disappeared. New atmospheric pressure desorption ionization sources have been discovered and made available commercially. One completely new instrument, the orbitrap, based on a new mass analyser, has been developed and is now also available commercially. Improved accuracy in low-mass determination, even at low resolution, improvements in sensitivity, better detection limits and more efficient tandem mass spectrometry even on high-molecular-mass compounds are some of the main achievements. We have done our best to include them is this new edition. 

It is only partially satisfying to disprove one mechanism and clearly better to be able to say something positive about another. This we have done via the isolation, for the first time, of an intermediate in the isomerisation of one icosahedral heteroborane into another. 

We do not claim to have covered all relevant topics. For instance, we do not discuss our very broad efforts to support the building of new businesses (apart from e-businesses). However, we decided that there needed to be a design freeze at some point, and we have done our best to cover most of the major issues for the industry in depth. The very important issue of environmental management is not included here since this is not our field, and can be better covered by others. 

Conformational drawuigs reveal that the product has the larger group equatorial but it is not so easy this time to draw good conformations for the cyclization itself. We need to get the p orbitals of the alkenes pointing at each other. The best we can do is to form the new six-membered ring initially in a twist-boat conformation and flip it into a chair afterwards. You may well have done better. 

Core 316920 from the Landsort Deep is one example of disturbed sedimentation and thus unfavorable for comparison to the data of the other areas. At the depth 5-15 cm an abnormal decrease of the curves down to namral backgrounds is visible, indicating sedimentation of older sediments caused by sliding and/or resuspension at the slope of the basin. Anyway, the data are presented here because disturbed sedimentation is quite a normal process in many areas. A selection of cores from different sites of each of the basins (as we have done in the Eastern Gotland Basin) would have been better, but it is sometimes impossible. 

That we have to master oxygen and peroxygen chemistry better in the future than we have done previously, is also the result of a change that is beginning to... 

When we consider what others have done better than ourselves,... 

Of course, we remain solely responsible for the defects we have not been able to correct. We count on the readers to help us solving this optimization problem. Our electronic addresses are below. If you know of places where we could have done better, we will be most interested in hearing from you. 

It is about time that we finished this session. Professor SUDAN thinks that there is a better way to illustrate these concepts than we have done, and I would like to ask him to write his grouping on the board and explain it.
