Low-temperature acidic melts of Bazman volcano (Iran)

The inclusions of a silicate melt were investigated in quartz insets of the extrusive rhyolite collected at Bazman Cenozoic volcano (Iran) and associated with the process of recent subduction. Low temperatures of the silicate melt along with high concentrations of water in the melt are ascertained. The microelemental composition of the melt showed a similarity to acidic melts of island-arc formations.

MICROELEMENTAL COMPOSITION OF HAIR IN DIFFUSE TELOGENOUS ALOPECIA

Adverse environmental conditions may affect the condition of the hair follicle, which require the optimal amount and ratio of minerals. The description of the diagnosis and treatment of microelements in patients suffering from diffuse telogen alopecia is presented. Based on the analysis of data from the literature review and the results of treatment of groups of patients the importance of identifying microelement imbalance in order to apply effective treatments is shown. The results obtained, showing the imbalance of macro - and micronutrients, including essential, are the basis for recommendations for patients with diffuse alopecia additional examination for definition of microelement composition of hair. This allows to prescribe different composition of microelement complexes that ensure the replenishment of certain microelements deficiency. And this provides an opportunity to reasonably resolve the issue of the need to include in the treatment plan detoxification measures to reduce the content of toxic and conditionally toxic microelements in the body.

Interdisciplinary Research of Iron Casting Technologies in the Town of Juketau during the Golden Horde Period

The work features the results of interdisciplinary research of cast iron dishware fragments discovered in the territory of one of the largest towns of the Volga-Kama region in the Golden Horde period. The microstructure of cast iron samples and surface mapping have been studied using scanning electron microscopy (SEM), and the microelemental composition was determined by emission spectral analysis (ESA). The characteristic features of the manufacturing technology have been revealed as a result of research of the elemental and phase composition across the area of the transverse fracture and longitudinal polished section. The results of SEM allowed to carry out a comparative analysis with archaological material from the territory of Bolgar settlement – capital of the Bolgar Ulus of the Golden Horde. According to the results of microelemental analysis, two groups of cast iron were determined with differences attributed to various sources of raw material.

Advantages of Porous TiNi Materials for Dental Implants in Diabetes Mellitus Patients

Structural changes in osseous tissue under surgically modeled diabetes mellitus in rabbits are studied experimentally with the focus on macro- and microelemental composition. The effect of growth factors on regeneration of mucosa is analyzed in Brattlebororats with inherited diabetes insipidus. Larger animals, dogs, were used to study the morphology of osseointegration with various implant materials under experimental surgical diabetes mellitus. The advantages of porous implants over other materials are shown.
