Manufacture of desired end products by means of fine treatment of coal tar resin
The possibility of desired end product manufacture from by-product coke industry wastes is shown. A large number of valuable products can be obtained from different fractions of coal tar resin by their fine treatment. The products obtained in this way find application in medical and chemical industries and etc. Moreover, recycling of by-product coke wastes into end products solves the problem of their utilization

Anticorrosive properties of epoxy coatings, impregnated with manganese-containing pigments
Β© Research India Publications 2015. Most inhibiting pigments, imparting high anticonosive properties to the primer modern metal materials, contain extremely oxidated chromium, and as a consequence, are toxic. Search for low-toxic pigments comparable on the effectiveness of the protective effect with chioiniuin-containing pigments remains today an urgent task. As a film-forming material, it was used the epoxy oligomer E-40 being widely applicable in the paint industry epoxy, for which, polyethylene polyamine served as a hardener. Calcining calcium manganite, manganite-co-precipitated calcium silicate, and manganese blue were chosen as anticonosive pigments, the properties of anticonosi\*e coating on the basis of epoxy oligomer E-40 pigmented with manganese compounds were investigated. It has been found that inclusion of the synthesized pigment into composition of coatings enhances their ability to inhibit undeiβfilm corrosion of steel. It has been proposed compounds of anticonosive primers on the effectiveness of protective action, surpassing industrial counterparts. The paper investigates influence of the content and nature of manganese anticonosive pigments on the protective properties of epoxy coatings. It has been shown that in the region of pigmentation below the critical, there is an increase of auticonosion efficiency of coatings. It has been evaluated the critical volume content of pigment, developed the formulations of primers, coatings on the basis of which the effectiveness of corrosion exceed the industry analogue
Mass open online courses - features and prospects
The government of the Russian Federation adopted the state program "Development of Education", which pointed to the need to develop online courses. the article contains a brief history of MOOC, an online model of courses. The main place is given to issues related to the merits and demerits of online courses in comparison with traditional onesΠΡΠ°Π²ΠΈΡΠ΅Π»ΡΡΡΠ²ΠΎΠΌ Π ΠΎΡΡΠΈΠΉΡΠΊΠΎΠΉ Π€Π΅Π΄Π΅ΡΠ°ΡΠΈΠΈ ΠΏΡΠΈΠ½ΡΡΠ° Π³ΠΎΡΡΠ΄Π°ΡΡΡΠ²Π΅Π½Π½Π°Ρ ΠΏΡΠΎΠ³ΡΠ°ΠΌΠΌΠ° "Π Π°Π·Π²ΠΈΡΠΈΠ΅ ΠΎΠ±ΡΠ°Π·ΠΎΠ²Π°Π½ΠΈΡ", Π² ΠΊΠΎΡΠΎΡΠΎΠΉ ΡΠΊΠ°Π·ΡΠ²Π°Π»ΠΎΡΡ Π½Π° Π½Π΅ΠΎΠ±Ρ
