Abstract<title> SUMMARY </title>During the XVIIIth century hydrotherapy knew a renewed interest both in Italy and the rest of Europe. A deep scientific research followed which revealed the chemical composition of waters since long believed to be medicinal. Chemical science played an important role even though it failed to explain exhaustively the grounds of the mysterious therapeutic properties hidden in such waters.<?CTRLerr type="1" mess="PBlanc posé à Verifier !" ?> As a matter of fact it contributed to arrange more functional exploitation methods of water sources in the first half of the nineteenth century, to boost industrial production of artificial mineral waters and to find out all possible medical applications of the recently discovered mineral springs. This research deals with such different applications of chemical knowledge, pointing out examples of the situation in nineteenth-century Trentino.

In the article, in the socio-geographical direction, issues are discussed about the territory of mineral and thermal waters on the southern slope of the Greater Caucasus, the chemical composition of waters, temperature, the possibility of using it in the treatment of some diseases, ecotourism value and rational use of thermal waters. Ecotourism can provide real financial support for nature conservation and increase the importance of natural sites that should be preserved in their original form. For the rational use of thermal waters in the research area, targeted measures should be taken at the state level, in order to eliminate the shortages in this area and to ensure its further development, entrepreneurs should be provided with very low interest rates, long-term loans. In the study of thermal and mineral waters, the merit of geologists, hydrogeologists and balneologists was great; in the modern period, scientists and specialists mainly refer to information obtained 50-100 years ago. There are very few innovations in this area. Favorable climatic conditions of the region, ecotourism conditions, large forests, natural and historical monuments, high seismicity of the territory, deforestation processes, and so on. according to specifications differ. The study area (especially the Gakh region) is the region with the richest thermal and mineral water resources in Azerbaijan, as well as ecotourism and balneological tourism. The Gakh region in the northwestern part of Azerbaijan, along with other natural benefits, is distinguished by its thermal and mineral springs and balneological value. The well-known hydrogen sulfide, hydrocarbonate groups of the Ilisu thermal waters, as well as the resort-tourist and balneological significance of the mineral springs on the left and right banks of the Kurmukh River near the village of Alibeyli and in the so-called boiling zone have not yet been fully utilized. Thermal and mineral waters, with the exception of a few, were used in a very primitive form mainly by the local population. The use of such waters should be carried out under the supervision of a physician for his purpose, and the taking or not taking medicinal baths should be especially controlled. Therefore, the chemical composition of thermal waters must be periodically checked by professional specialists.

Therapeutic Properties

Mare’s milk has long been considered to have special nutritive and therapeutic properties in Mongolia and southern states of the former Soviet Union. It is now gaining popularity in some parts in Europe also. Mares’ milk is characterized by their unique nutritional profile. Therefore, interest has increased in the use of mare’s milk for human nutrition in the past several years, especially in France and Germany. As compared to many other mammal species, mare’s milk is highly appreciated for similarity to human milk in terms of chemical composition allowing its use as a substitute for mother’s milk in infant feeding. Mare’s milk also has been used for the treatment of certain human pathologies such as hepatitis, chronic ulcer and tuberculosis. This review dwells on the chemical composition, nutritional value and various health-promoting properties of mare’s milk.

Absorption Of Light

The emission and absorption of light by atoms produces discrete sets of spectral lines that were a vital clue to unravelling the structure of atoms and their elucidation was an important step towards the development of quantum mechanics. In the middle years of the nineteenth century Bunsen and Kirchhoff discovered that spectral lines can be used to determine the chemical composition of stars. Following Rutherford’s discovery of the nucleus, Bohr devised a model of the hydrogen atom that explained the spectral lines that it produces. His work was developed further by Pauli, who postulated the exclusion principle in order to explain the structure of other types of atom. This enabled him to explain the layout of the Periodic Table and the chemical properties of the elements.

Personal Experiences

A historical ecology perspective permits an understanding and appreciation of the breadth of influences brought to bear on human events in time and place. Kentucky’s nineteenth-century distilling industry converted from traditional craft work to mechanized industrial production in a very complex process that blended environmental context with Old World knowledge, invention and innovation, associations with complementary industries, and conjunctions with a range of other economic, political, and social processes. Such linkages improved productivity but also introduced chains of contingencies and risk. The telling of this story and the underwriting of its authenticity are supported by archives that record how people of differing backgrounds and experiences, be they innovators or managers or laborers, enslaved or free, contributed to the industry’s development. Much of their work and many of their personal experiences are anonymous, but they are collectively represented in documents, narratives, and landscape.

Quenching And Tempering

This study investigates the influence of the substitution of chromium (-0.8 wt.−%) by manganese (+1.3 wt.−%) in a standard quench and tempering steel and the predictability of property changes through simple simulations, only dependent on the chemical composition. The substitution of chromium by manganese leads to an increased hardness (+50 HV10) and a reduction of the critical cooling speed from 19 K s−1 for the reference alloys to 9 K s−1 for the new alloy and a nearly constant hardness of (600 HV10) after Jominy-test. The commercial software JMATPRO is used to simulate and predict key properties for the industrial production. It is shown that a successful simulation of phase transformation temperatures and the general directions of change can be predicted, but more complex properties like critical cooling rates or hardenability need more sophisticated methods.
