The data obtained here show a gain in the catalytic efficiency of copper species after a neutralization treatment. However, at the trace concentrations of copper that are found in most paper, this effect would be so small that it can be disregarded. 

Moreover, since the catalysts are applied to function at around 700°C during the ignition step of the methane combustion process [2], the thermal treatment effect on the texture, the structure and the activity of the catalysts are investigated in this paper. 

In order to make a new catalyst for the ammoxidation of acrylonitrile, we decided to mix these two systems SbA, in order to activate the paraffin, and Sn/Sb, having already been utilized to ammoxidate the relative olefin. In this paper, the effects of the method of preparation and calcination of a Sn-V-Sb mixed oxide on its catalytic performance are analysed. In particular we changed the medium in which the starting material were dissolved, utilizing ethanol, iso-butanol and water, in order to understand the interaction between the solvent and the metallic ions and to enhance the performance of the catalyst. Moreover we made a mixture of oxides and hydroxide in n-hexane to compare the coprecipitation with a simple mixture. The catalyst with the best performance was then calcined at different temperatures and in different atmospheres in order to optimize the thermal treatment. 

Simpson s paradox is a phenomenon whereby an overall treatment effect in one direction is reversed in every stratum. It is named after a paper of 19 51 in which it was extensively examined by E.H. Simpson (Simpson, 1951), although a related phenomenon had been discussed at least as early as 1899 by Karl Pearson (Pearson et al., 1899). (See Aldrich (1995) for discussion.) A hypothetical example is given in Table 9.1, in which a trial has been run comparing two treatments in two strata of patients moderately ill and... 

Suppose that we have observed a given (one-sided) P-value in a clinical trial say P = , what is the probability that in a second trial of similar precision for which we will also calculate a P-value, say, P = a2, that we will find that the P-value is now lower than the first. In other words, what is the probability that aj prior distribution for the treatment effect before running the first trial or (b) the true treatment effect was equal to the observed treatment effect from the first trial. 

Thus the ZnO is a nonvolatile base that can be placed in the paper by a gaseous substance. This process seems very promising. However, the major disadvantage of this process (there are always disadvantages) is that diethyl zinc is very flammable and great care must be exercised in its use. This leads to another question Is the treatment effective enough to be worth the risks involved Only through more experiments can this question be answered. 

Alkaline treatment of the pulp results in papers with enhanced tensile strength. It is helieved that the alkaline treatment effects hydrolysis reaction of the surface of the polymer. Thus the surface contains an increased amount of amino groups. These materials can be used in slipping clutches.
