From the beginnings of contemporary chemistry, molecular constitution has been a full of life region of study and hypothesis. For greater than part a century spectroscopy and different equipment were to be had to symbolize the constructions and shapes of molecules, fairly those who are inflexible. in spite of the fact that, such a lot molecules are a minimum of to some extent non-rigid and this non-rigidity performs an incredible position in such diversified components as organic task, power move, and chemical reactivity.
Info structures technology is quickly advancing in lots of instructions. Di versified rules, methodologies, and methods in addition to functions were conceived and constructed. This sequence intends to debate the various fresh advances during this box. during this quantity, we hide 4 well timed subject matters that are of significant present curiosity.

La reponse a cette question est tres delicate, en raison de la longueur et du cout eleve des experimentations necessaires pour reveler la potentialite cancerogene, avec, en plus, les difficultes frequentes d'interpretation que nous avons soulignees. Des exigences trop severes risquent en effet de decourager la recherche therapeutique dans l'industrie, d'autant que les drogues, dont la fabrication et la commercialisation est envisagee, sont loin de connaitre toutes Ie succes et, pour la grande majorite d'entre elles, sont meme destinees a etre abandonnees.
With the present methods of investigation, it is questionable, for instance, if differences between the thymic atrophy caused by a carcinogenic polycyclic hydrocarbon or by urethan and that caused by cortisone can be ascertained, although the former compounds will induce a high percentage of thymic lymphosarcomas, and the latter will not; the same consideration applies to the thymic repair and hyperplasia which follow atrophy. However, the study of the kinetics of these changes, may be rewarding (FIORE-DONATI and KAYE, 1964).
