Using quantum mechanics, he proposes to explain the origins of the world from the point of view of quantum theory. He believes to find in the cosmic rays the manifestation of the initial fragmentation. However, regardless of the adopted cosmology, the hypothesis of the primeval atom (cold big bang) had no equation to support it and was not retained. Like all other cosmologists, he fell back on the Friedmann-Einstein equation with a repulsive cosmological constant which, according to supernova observations at the end of the millennium, propels expansion towards infinity. We juxtapose our equation of “quantum cosmology” to this equation of relativistic cosmology. We have already proposed this equation in an earlier paper [3], which has its source in quantum mechanics and fits Lemaître’s hypothesis of the “primeval atom”. It’s an equation in which the concept of matter-space-time is mathematically connected;gravitation and electromagnetism are also bound by space-time. A mechanism is described showing how velocity, time, distance, matter and energy, are correlated. We are led to ascertain that gravity and electricity are two distinct manifestations of a single underlying process: electrogravitation. For the first time, the cosmological time, considered as a real physical object, is integrated into a “cosmological equation” which makes coherent what we know regarding the time (its origin, its flow…), the matter and the space. Moreover, the equation indicates a constantly decelerated expansion. The concentration of the material medium and the importance of the decreasing energy of the vacuum contribute to the progressive increase of the positive pressure which becomes responsible for the increasing deceleration of the expansion.

Soil microorganisms are very sensitive reagents on influence of biotical factors, and at the same time are the active producers of phytotoxic and phytostimulating exometabolites. Studies of soil microbiota were conducted in virgin beech forests of Shyrokoluzhansky massif of the Carpathian Biosphere Reserve. It was found the ratio and the number of different ecological-trophic groups of soil microorganisms changes with altitude. So the number of ammonificators with increasing of altitude above sea level was reduced. The soil at altitude of 1,100 meters above sea level was characterized by minimum content of organotrophes -1.22 × 10^6 （CFU-colony forming units/lg.a.d.s.）. At the altitude of 500 meters content of ammonificators increased at six times and was 7.07 ×10^6 CFU/lg.a.d.s., which indicates to accumulation of the soil organic matter. Similar changes occurred with the number of bacteria which are using mineral forms of nitrogen for their nutrition. Their maximum quantity （4.32 × 10^6 CFU/lg.a.d.s.） was in the soil of biotope disposed at altitude of 500 meters above sea level. Fluctuations in the number of soil micromycetes of virgin forest ecosystems have not been as significant as the bacterial microbiota （within 17 ×10^3-28 × 10^3 CFU/lg.a.d.s.）. Among a wide spectrum of bacterial microbiota were isolated strains with high phytostimulating action.展开更多

It is the first time that an archaic Homo sapiens fossil has been unearthed from the Three Gorges Region. Engravings on the Stegodon tusk appear in groups,making up simple and abstract images. It is the earliest known engravings created by human beings; it exhibits great potential for the study of the origin of art and the development of ancient cultures in south China and bears important implications for the origin of modern humans in East Asia.展开更多
