Biocides for the protection of petroleum products and materials from biological influences

Petroleum products and other materials with a high percentage of hydrocarbon can change their main operational properties due to biological influences. Thus, a high-performance biocide for the protection of petroleum products, emulsions, emulsols, paints and primers, lubricating and cooling liquids, mineral oils, equipment for water circulation systems and refinery chilling, materials and equipment at plants from biofuels was proposed.

Effective Constructive Decisions about Reconstruction, Expansion and Strengthening of the Highway Bridges

Wedeveloped an effective reconstruction system of the existing bridges with the expansion of the span clearance by different types of reinforced concrete imposed slab with protruding consoles without the extension of pillar. At the same time the beams are strengthened by the change of their static scheme from freely leaned to rigid or completely strangulated beam on pillars at the maximum preservation of the existing structures and provision of clearance and capacity required by the current design regulations of the new bridges.

VLSI Schemes Complex for Synthesis of the Real-time Artificial Neural Networks

The complex is designed for synthesis of the artificial neural networks working in real time based on the programmable logic device (PLD), and provides the following functions: calculation of sumof the paired products; calculation of the transfer function; implementation of themodules of learning management and functioning of the neural element; creation of the neural elements of different types; implementation of the different kinds of artificial neural networks on their basis.

Plasma Chemical Technology of the Polymeric Sulphur

Polymer sulphur can be get as a result of controlled cooling of the decomposition products of hydrogen sulphide or sulphur vapor processing in ultra-high-frequency plasma.

Polymeric sulphur is used as a vulcanizer to produce high quality automobile and aircraft tires, characterized by high flexibility and better ability to perceive the dynamic loads, and by the high abrasion resistance.

Polymeric sulphur can effectively absorb the ionizing radiation, so it should be used for obtaining the materials with radiation-protective properties.
