Analysis of these data for sex-difference was only reported in 57 studies, with 54 of these studies reporting a sex-difference (42 in subjects > 17 years and 12 in subjects < 17 years). In accord with the well documented greater pain sensitivity in females compared with males, in all ...
Combustion reaction is a chemical change in which oxygen reacts with another substance, often producing energy in the form of heat and light. The main and final thing I can add to my essay is that the reactions are very important for chemist. I think that the reactions for chemist are lik...
Catalytic asymmetric reactions promoted by metal catalysts and chiral phosphoric acids have become useful processes for the preparation of structurally diverse and complex organic compounds. This JOCSynopsis provides an overview of the most recent developments made in studies of these reactions. The paper...
In this paper, we will start with the issue of the cognitive impenetrability of emotion-producing processes. It turns out that, while there is abundant evidence of emotion-producing processes that are not cognitively impenetrable, some nonetheless are. We will look at two sorts of case. The ...
Symmetry rules for predicting the course of chemical reactions Rules are given for a reaction of any molecularity which show whether it is allowed or forbidden by orbital symmetry properties. The rules are based on a rigorous treatment, but correspond to simple concepts in practice. A rough MO ...

lives indefinitely in benzene solution in equilibrium with a dimer: Its stability is accounted for in part by the delocalization of the unpaired electron and in part by the steric forces inhibiting its reactions, for the conversion of the planar tervalent carbon atom into a tetravalent atom involve...
