Rivne – Since independence many Ukrainian scientists went abroad and now advance science at leading universities around the world. But there are other examples where scientists remain in Ukraine, and still their work is recognized worldwide. Rivne professor Leonid Dvorkin also received many interesting proposals and invitations, but he is still working in Ukraine. He authored 35 monographs and textbooks, and registered more than 70 patents and inventions in the field of construction material technology. Recently, his home city witnessed the presentation of a textbook Construction Materials, which was published by a major American publishing house Nova Science Publishers in New York. The book’s authors are head of Construction Materials Technology and Materials Science Department in the National University of Water Management and Natural Resources, Sc.D. in Technology, Professor Leonid Dvorkin and professor of the same department Oleg Dvorkin. The textbook Construction Materials is based on modern international scientific achievements, and complements and develops them. The authors translated it into English themselves. The American publisher noted their efficiency and professionalism. The father and son duo are leading scientists in the study of construction materials and concrete technology, known not only in Ukraine but also far beyond its borders. Their works have been published in many countries. The textbook is designed for the use of a wide range of English-speaking professionals. Professor Dvorkin explains: “It will be a guide for American foremen and construction workers.” It can be used by those Ukrainian experts and students who wish to learn modern international terminology and acquaint themselves with the requirements of the US and European regulations.
