In arctic zone of West Siberia, native people’s bodies were sometimes mummified inside the medieval graves. In2013 to 2017, we conducted the excavations of medieval graves at Zeleny Yar cemetery in Yamalo-Nenets Autonomous Okrug. Among the burials, current report deals with the mummy grave #79. During the investigation, bronze plate and strips, woven or fur clothing, leather strap, beads, bronze bracelets, and iron knife etc. were collected. Anatomical and radiological research showed that the mummy was found intact with hair, skin, and skeletons, but the preservation status of soft tissue differed greatly depending on the area. The brain and eyes were well preserved, but the chest and abdominal organs almost disappeared. The arms were preserved to some extent, but only the bones remained in the legs. The West Siberian mummy could be a great resource for anthropologists to reveal the biological aspects of arctic indigenous people.

The aim of this parasitological study is examining contemporary (the late 20th century) specimens of the arctic or subarctic areas in Western Siberia and comparing them with the information acquired from archaeological samples from the same area. In the contemporary specimens, we observed the parasite eggs of 3 different species: Opisthochis felineus, Ascaris lumbricoides, and Enterobius vermicularis. Meanwhile, in archaeoparasitological results of Vesakoyakha, Kikki-Akki, and Nyamboyto I burial grounds, the eggs of Diphyllobothrium and Taenia spp. were found while no nematode (soil-transmitted) eggs were observed in the same samples. In this study, we concluded helminth infection pattern among the arctic and subarctic peoples of Western Siberia throughout history as follows: the raw fish-eating tradition did not un-dergo radical change in the area at least since the 18th century; and A. lumbricoides or E. vermicularis did not infect the inhabitants of this area before 20th century. With respect to the Western Siberia, we caught glimpse of the parasite infection pattern prevalent therein via investigations on contemporary and archaeoparasitological specimens.

The mechanism of protonic relaxation is shown to take place in molecular systems containing hydrogen bonds. The mechanism arises from the proton redistribution between two stable states on hydrogen bond lines. This redistribution occurs due to changes of hydrogen bond double well potential, brought about by changes of the electronic state of a molecular system. A characteristic of the relaxation process is that it takes place due to the proton tunneling along hydrogen bonds. The charge shift causes electrostatic potential variation in the electron localization area, which leads to the shift of molecular system energy levels and changes its redox potential. The characteristic time of the protonic relaxation is shown to depend essentially on hydrogen bond bending strain, which increases with the temperature rise and decreases abruptly the efficiency of proton redistribution. Hence, the rate of this process decreases with temperature, in contrast to the activation process. This relaxation process is shown to be responsible for energetic characteristics of recombination reaction $P^+{Q_A}^-{\rightarrow}PQ_A$ (free energy difference ${\Delta}G$ and/or reorganization energy $\lambda$), temperature dependence in Rhodobacter sphaeroides RC.
