Coronavirus was finded to have characteristic pattern of chemical-physical properties at X-ray cristallograpy.This fact influence some diffusion properties related also Brownian moto and shielding effect .Not only carrier size is relevant for airborne transmission of some respiratory virus but also virus size and electrical feature, envelope composition and other .WU HAN, and other variant like DELTA and OMICRON show different transmissibility pattern.The virus envelope seem involved in avoiding strategies of virus to escape to the hosts immune system.In this work aspect related...

NERVOUS SYSTEM FUNCTIONS, EVOLUTIVE PATTERN , AND RELATIONSHIP WITH SOME NEURODEGENERATIVE CONDITION: The nervous system directs and coordinates our movements. It receives stimuli from the environment around us and from all our internal organs. It interprets these stimuli and elaborates responses, which are transmitted to muscles or glands.To compare the nervous systems of invertebrates to vertebrates and between the various vertebrates Can be an useful instrument in field fo neuroscience, molecular biology, forensic science, and pharmacology, regenerative medicine. Why in example some...

The central nervous system (CNS) is the only organ system of the body which lacks its own waste clearance or lymphatic system, a system which helps in removal of metabolic byproducts and waste solutes. Although the brain plays its role in 25% metabolism of body and comprises only 2% of the total body mass, this high metabolic load needs a proficient system for the removal of waste solutes and for maintaining homeostasis of brain environment. Well-depicted components of waste removal comprise of perivascular fluid flow and phagocytic immune cell functions, nonetheless, the requirement for...

Aim of this work is to verify difference in spread attitudes of covid-19 and other coronavirus versus Smalpox and try to seek rational explain of the specific pattern of diffusion. The rapid increase of covid- 19 cases in FRANCE in second wave in fisrt day of october 2020 seem to follow not only a diffusion related direct contact and by droplet but also by airborne trasmission. A real fact is the diffenece in size of virus smalpox vs coronaviruses. Virus size is an relevant factor involved in kind of spread.

In order to enrich and expand this topic information whit an update searches, new studies and allows widely benefits international. Hence this work was written in Italian and English languages. The recent study was verified the statistical hypotesis of prevalence and distribution of covid-19 related some Relevant division of high way in italy (especially north regions). The geomorphological characteristic of PIANURA PADANA , an area located in Italia which is also Named PO valley (a low area land between hills and mountains). This area is surrounded from the north by a close connection with a...
