  • The development of technologies of designing wetsuits

    The article introduces a new advanced algorithm design foam suit, taking into account the expected exploitation of clothing in conditions of hydrostatic pressure, which determined the rationale for the introduction of common cycle design work additional modules problem-analytical content. In these modules for information on effective parameters of dry constructions (human heat loss and required for the thickness of the thermal protection areas), calculations shall be made in the numerical simulation of sphere that iterations mode algorithm design, allow theoretically test the line selected foam it required thermal protection. The proposed algorithm justified by the peculiarities of traditional methods of designing clothes and existing development methods of calculation of wetsuits, as well as conformity of vector design priority market trends.

  • The Experimental Research for the Development of The Data Base of Mineral Waters

    The technologies of getting energy from the unlimited sources render possible to build the energy-independent houses with the ecologically clean infrastructure in remote areas and to solve the problems of the energy supply of the already-existing objects. In Azerbaijan and in Russia the mission-oriented research is carried out as both countries have either traditional or alternative stored energy sources, and much work is in progress on the parallel development of modern technologies of energy providing of human life support including technologies based on the use of mineral waters which are of interest in the field of bioengineering resources. The primary chemical and thermophysical properties of mineral waters underlie in creation of the technologies of the use of their resources. The special investigations on the determination of chemical properties of mineral waters of separate regions of the Stavropol Territory of the Russian Federation are substantiated and assumed in the article. In the paper the experimental works of the chemical composition of nine mineral waters of the sources of the regions of Pyatigorsk and Yessentuki cities are carried out by the methods of experimental atomic emission spectroscopy and ion chromatography. The major part of the established chemical elements includes sodium (Na) (from 844 up to 6620 mg/liter); then calcium (Ca) as one of the main sources of cations, and also kalium (K) and magnesium (Mg) (they compose from 6.7 up to 92.2 and 15 up to 76.2 mg/liter correspondingly). Sulfur (S) is also important with the quantity of 362 mg/liter; silicon is in sufficient number as part of these mineral waters – from 3.5 up to 27.3 mg/liter. The small part includes lithium (Li), boracium (B) and strontium (Sr). The findings render possible to expand the world data base of the corresponding natural resources of the Russian Federation for the development of the ecologically oriented technologies.
