continue the study of the Standard Model of Quantum Physics in the Clifford algebra of space. We get simplified mass
terms for the fermion part of the
wave. We insert the simplified equations in the frame of General Relativity. We construct the electromagnetic
field of the photon, alone boson without proper mass. We explain how the Pauli
principle comes from the equivalence principle of General Relativity. We transpose in the frame
of the algebra of space the second quantification of the electromagnetic field.
We discuss the changes introduced here.
Objectives: To explore if the dramatic
decrease in price of e-cigarette has transformed this new product into a product used for
tobacco initiation among a teenage population. Methods: The authors added a question in 2012
on e-cigarette in the yearly survey on tobacco consumption in Paris schoolchildren. The study is conducted
on a randomly selected sample from 2% of classes since 1991. Results: 277
(8.1%) of the 3409 schoolchildren studied (including 575 non responders
to this question) reported having had an experience with e-cigarette.
Experimentation rate is 6.4% among the 12 - 14-year-old,
11.8% among the 15 - 16-year-old and 9% among the 17-year-old schoolchildren. Among the
12 - 14- year-old schoolchildren, 64.4% of e-cigarette experimentation was by
non-smokers. Of the 17-year-old teenagers who had used e-cigarettes, 12.4% were
non-smokers. For the whole population, 33.2% of those having tried e-cigarette
are non-smoker, 22.7% occasional smoker, 3.6% ex-smoker and 40.4% daily smoker.
Those who experiment cannabis, shisha or binge-drinking are more frequently
users of e-cigarette. In the smoker group, there is an inverse trend of rela- tionship
between the readiness to quit tobacco and the rate of use of e-cigarette. Conclusion: For teenager’s, e-cigare- ttes have become not a product to aid quit
tobacco but a product for experimentation and initiation of cigarette use.
Regulation is urgently needed to control the emergent use of this new tobacco
product by children.
