The Future

In today's economy, chemical engineering must respond to the changing needs of the chemical process industry in order to meet market demands. The evolution of chemical engineering is necessary to remain competitive in global trade. The ability of chemical engineering to cope with managing complex systems met in scientific and technological problems is addressed in this paper. Chemical Engineering is vital for sustainability: to satisfy both the market requirements for specific end-use properties of products and the social and environmental constraints of industrial-scale processes. An integrated system approach of complex multidisciplinary, non-linear non-equilibrium processes and phenomena occurring on different length and time scales is required. This will be obtained due to breakthroughs in molecular modeling, scientific instrumentation and related signal processing and powerful computational tools. The future of chemical engineering can be summarized by four main objectives: (1) Increase productivity and selectivity through intensification of intelligent operations and a multiscale approach to processes control; (2) Design novel equipment based on scientific principles and new production methods: process intensification using multifunctional reactors and microengineering and microtechnology (3) Extend chemical engineering methodology to product design and engineering using the "triplet 3PE molecular Processes-Product-Process Engineering" approach; (4) Implement multiscale application of computational chemical engineering modeling and simulation to real-life situations from the molecular scale to the production scale.

The 1960S

Abstract Traditional solar salt pans appeared in Vinh Chau, Soc Trang province and Bac Lieu province in the 1960s (Do, 1998). Crude salt is mainly used for human consumption and to salt fish and fish sauces and therefore its demand is not considerable. Moreover, a large amount of crude salt was produced yearly at the sites which exceeded local consumption needs. Consequently, all salt produced could not be sold which reduced the income of salt farmers. Towards the end of the 1980s, an Artemia culture technique in salt pans for cyst production was developed by the College of Aquaculture and Fisheries (CAF), Cantho University, which proved to be more profitable than traditional salt production (Vu, 1997). Therefore the technique was immediately transferred to farmers and the production scale increased year by year. This case study describes the system of shrimp, Artemia and salt production which was introduced to salt farmers with the aim of developing a new production system to help to improve their living standards.

The paper is devoted to the economic analysis of rationality in the tradition of Harvey Leibenstein: the authors perceive rationality as “calculatedness” when making decisions, while the degree of this “calculatedness” is interpreted as a variable. Thus, this approach does not correspond to the generally accepted neoclassical interpretation of rationality, according to which rationality is both full and constant. The authors believe that such a neoclassical approach makes too stringent requirements for the abilities of people. In real life, people do not behave like calculating machines. The paper discusses various factors limiting the degree of rationality of individuals. One group of factors is associated with external information constraints such as the complexity and extensiveness of information, as well as the uncertainty of the future. Another group of factors is related to informal institutions. In particular, the paper states that the system of planned socialism contributes to less rationality than the system of market capitalism. Thus, in the post-socialist countries, including contemporary Russia, one should not expect a high degree of rationality of the behavior of economic entities. The paper mentions, in particular, the factors of rationality caused by informal institutions, such as the propensity to calculate, the propensity to be independent when making decisions and the propensity to set goals. The authors also believe that people who live on their own are usually more rational than people who share a common household with someone else. This assumption is verified econometrically based on data on young urban residents collected by the authors. It turned out that the behavior of people included in this database, in general, corresponds to what the authors believed.
