The article reviews physical development of teenagers living in extreme climate conditions. The influence of various factors on physical development leads to phenotypical changes. The environment influences much on the children’s organism as due to genetic plasticity and lability it is more acquisitive to unfavorable factors. Researches in the North where residing conditions are severe enough, considering extreme factors, such as long period of low temperatures, sharp day differences of atmospheric pressure, polar night, deficiency of solar radiation, etc., have revealed delay of terms of the beginning of growth activity, a great speed of transit of separate stages of the organism development, the accelerated maturing and early biological maturity which is explained as a phenotype approaching to the special ecological conditions.

The data of appeal to the ambulance station with hypertensive crises of residents of Yakutsk -with a geomagnetic field at the maximum (2013) and a minimum (2017) of the XXIV solar cycle was compared. It is shown that in the years of high solar activity, the effects of geomagnetic storms are manifested in the increase in the number of calls for emergency medical care with a preliminary diagnosis of the hypertensive crisis. At the same time, the majority are elderly and senile people, who, are believed, to have a cardiovascular system more susceptible to the influence of geophysical perturbations. An increase in the number of patients with hypertensive crisis is observed not only on the day of the maximum decrease of the Dst-index (the 0th day of the storm), but also in the interval from the -2th to the 2nd day of the storm. Differences in the reaction time are revealed depending on the type of geomagnetic storm: during sporadic storms, the maximum of calls is most often on the - 1st day, and for recurrent ones - on the 0th day.

In view of climate warming, there is a need for parameterization of boundary conditions in predictive assessments of the ground temperature regime in cold regions. For this, an experimental study has been conducted at the Tuymaada monitoring site of Melnikov Permafrost Institute of the SB RAS to investigate the ground thermal regime following the removal of snow and vegetation covers. Field data have been collected for a two-year cycle. These data are compared with the findings from a similar study performed by A. V. Pavlov in the early 1970s. During this period, the mean annual air temperature has increased by 2.6 °C. As a result, the mean annual ground temperature at a depth of 3 m has warmed by 0.6 °C at the undisturbed site and by 1.4 °C at the disturbed site, with the ground properties remaining virtually unchanged. It is therefore evident that the current changes in climate and its elements should be taking into account during engineering design and ground temperature regime forecasts.

Potential of GPR data for evaluation of rocks humidity is considered. A method for evaluation of humidity of dispersed rocks by an empirical formula is proposed, which is based on determination of a relative change in the delay time (N) of GPR signals reflected from interfaces of media in frozen (tM, ns) and thawed (tT, ns) condition. The method was tested in field conditions at two sites in Central Yakutia. The GPR data are considered within an active layer, in a period of complete freezing and defrosting of the rocks. In the first site of testing the data values were taken from a part of a profile in the vicinity of the borehole test drilling. The average time delay of a GPR signal from the reference boundary at the depth of 1.7 m was calculated by three neighboring points of sounding. The relative change of the delay time of the signals Nt is evaluated. The average humidity content is calculated by the proposed formula. In accordance with the method the humidity distribution along the GPR profile in the second site of testing is also determined. Application of the method will allow to evaluate humidity of dispersed rocks remotely and its changes under the influence of various climatic and anthropogenic factors within the active layer of the permafrost zone rock mass.

The article is devoted to the problem of wear and tear ofparts of mining equipment working with frozen soils under low climatic temperatures and the development of a method for restoring the crowns of excavator buckets teeth and bulldozer ripper with increased performance characteristics. Deposited layers obtained by overlaying surfacing with self-shielded flux cored wire and surfacing electrodes T590 (widely used in production) for surfacing with direct current and pulse mode modulated current are investigated. It is shown that when surfacing by a pulse-arc method with T590 electrodes, the content of the main alloying elements (manganese, silicon, nickel, chromium) in the weld layer is higher than in the case of surfacing by a direct current. It has been established that the microhardness of the deposited layers at surfacing by direct current is greater than when surfacing with modulated current. The way of rework of geometrical sizes of worn-out details of mining equipment using electrodes of the E-50A type at pulsed arc welding and further hardening of a surface layer of rework details using coating material with the increased physicomechanical properties is offered. Full-scale tests of the details reworked by this method and further operation at the enterprises of the Republic of Sakha (Yakutia) have shown their operability and economic reasonability.

The work contains results ofpetrologic estimates of crystallization conditions of several generations ofpyroxenes and amphiboles from the Mesozoic igneous rocks of poorly studied Dzheltulin alkali massif, being the biggest magmatic structure of the Tyrkandin ore region, located in the eastern part of the Aldan-Stanovoy shield. According to the results of authors' identification ofphysical-chemical conditions, existed during pyroxene crystallization, one can judge about their crystallization at different temperatures and at two depth levels. Amphiboles of the earlier intrusions are characterized by relatively high contents of alkalies and aluminium, later intrusion - by high silicon content. Two levels of crystallization conditions are determined for amphiboles from massif rocks, as well as for pyroxenes. It is found that, petrologic characteristics of dark-colored minerals from the Dzheltulin massif rocks reflect features of deep structure of the Earth's crust. It is also concluded that, interpreted depth anomalies at attribute seismic section of the main frequency of local wave packets, probably reflect the Mesozoic intermediate magma chamber and channels. Besides, relation of anomalies with the Mesozoic alkali intrusions suggests that mantle channels identified at section of the main frequency of seismic waves, are of the Mesozoic age.

A comparative analysis of the chemical composition of spinel macrocrystals from the concentrate of diamondiferous tuffites basal horizon and spinel microcrystallites from the binder mass of lapilli with those from kimberlite pipes of Yakutia is made for determining specific features of the medium transporting these rocks to the surface. It is established that most of chrome spinels belong to high and medium-chromium picrochromites. The presence of high and medium-chromium spinels in the interval of one sample indicates a deep origin of the melt. Chemical compositions of spinels from tuffites and highly diamondiferous kimberlites vary considerably, spinels from the Mir pipe are characterized by direct correlation between AhO3 and Cr2O3, for spinels from tuffites this trend is not observed; a significantly higher content of ТЮ2 is typical for the tuffite spinels that can be attributed to a particular source type. Melt inclusions in chrome spinels are studied by electron microprobe analysis and Raman spectroscopy. Olivine, pyroxene, phlogopite and nephe-line phases are identified in the melt inclusions.
