Technological Innovations for Ecologically Sustainable Development: The Case of Chemical and Energy Industries in the Context of Energo- chemical Systems Technologies Development

This paper is aimed at the identification and evaluation of various development paths for the energy and chemical industries. This is to be embedded in the broader philosophy of the so-called Ecologically Sustainable Development (ESD). We focus our attention on the Polish energy and chemical industries since their development seems to be one of the key factors within the context of ESD. Assuming a strategic option described by Haefele (Novel Horizontally Integrated Energy Systems -- NHIES) as a target structure for the next century, we present various development alternatives which may be paths leading to the target. This view if one of the results of our research in the field of development for the chemical industry in Poland. As this research is regionally oriented, we take into consideration the possibilities of utilizing two coal and lignite conversion technologies (PYGAS and PYREG). We show their reliability within the ESD context when these technologies will be introduced in the chemical and energy and power industries

The condition of the intellectual potential and platform chemicals base for the production of engineering polymers in Poland. Shell we be able to keep up with the main global players?

W opinii ekspertów tworzywa inżynieryjne i agrochemikalia stanowią jedyne branże, w których europejski przemysł chemiczny może skutecznie konkurować na rynku globalnym. Polskie spółki sektora Wielkiej Syntezy Chemicznej od lat nie wykazują wysokomarżowego rozwoju down-stream. W pracy przeprowadzono ocenę możliwości rozwoju obszaru chemikaliów inżynieryjnych w Polsce, z uwzględnieniem trendów światowych, kompetencji i tradycji polskich firm oraz zaplecza badawczego, a także niedomagań obszaru wytwórczego chemikaliów platformowych.In the opinion of experts, engineering polymers and agrochemicals are the only fields, in which the European chemical industry can successfully compete in the global market. Polish companies which are grouped in the Great Chemical Synthesis sector have not shown any high gain development down-stream for years. An analysis of the potentials for growth in the field of engineering chemicals in Poland, taking into consideration global trends, the competence and tradition of Polish companies and their R&D base as well as the shortcomings of the production sector of platform chemicals have been presented

Analysis of Involutional Ciphers: Khazad And Anubis

In this paper we study structural properties of SPN ciphers in which both the S-boxes and the affine layers are involutions. We apply our observations to the recently designed Rijndael-like ciphers Khazad and Anubis, and show several interesting properties of these ciphers. We also show that 5-round Khazad has 2 weak keys under a "slide-with-a-twist" attack distinguisher. This is the first cryptanalytic result which is better than exhaustive search for 5-round Khazad. Analysis presented in this paper is generic and applies to a large class of ciphers built from involutional components
