Abstract

Civilization of people is presented as a thermodynamic nonequilibrium system with all types of human activity including the territory of residence. The main types and aspects of human’s activity are presented as thermo dynamic energies or extensials, and their derivatives as the speed of their development or intensials. Territories of peoples' residence are presented as hierarchies of areas or volumes of the thermodynamic nonequilibrium system. The representation of states or their unions in the form of thermodynamic models of nonequilibrium systems with their equations and taking into account the hierarchy of their sub-territories that give a possibility to calculate and avoid wars, revolutions, pandemics in certain states, unions of states and continents. Separately, given an group of equations for taking into account the relations of individuals in society, their consumer basket, an increasing or decreasing in the population of people living in a given territory. Thermodynamic nonequilibrium models and equations have been applied for expansion and filling by civilization of new territories and transition her to a new level.

Abstract

A study about the use of medications (indication-prescription) was realized, prospective in patients with buccal illness, using a tincture at 10 % from Calendula officinalis as therapeutic option, in four different clinics in Havana City, Cuba. 110 patients were chosen randomly, and were collected data from 60 physicians. Results were measured as treatmentresponse, time of improvement and used dosis with time of improvement. The sample answered to the treatment at 90 %, and from them, 73.7 % in a period between 3-6 days, and 26.3 % in a period of 7-10 days. Calendula officinalis tincture at 10 % was effective in treatment of buccal infections corroborating its antibacterial and anti-inflammatories properties due to the presence of volatile oils, and flavonoids, among others.
