As the largest contributor to production-based emissions, electricity generation sector has led huge carbon emission transmissions. This is first attempt explore latest features of transmissions from final domestic consumption China in 2002–2015, combining MRIO-based Structural Path Analysis and transmission-based method. Results show that: (1) Although inter-provincial are increasing significa...

Abstract Radioactivity, whether natural or artificial, today constitutes a significant segment in the process of protecting human and animal health. Natural radioactivity is an integral part our ecological system, so it has long been present food we eat. However, intensive industrial processes some areas have disturbed balance thus introduced into environment radionuclides quantities that can a...

Bullwhip effect has always been considered as one of the critical problems in a supply chain that negatively influences costs, inventory, reliability and other important business processes especially in upstream agents. This problem has become even more critical due to the increased complexity of global supply chains. This paper aims to develop a simulation approach based on system dynamics mod...

heavy water plus neutral current additive to an activity level of one decay per day per tonne ofD^O (DDT) for the thorium chain and(5(TpDTs for the uranium chain. /O jL^ It is equally important to be able to monitor these activity levels, by some form of ^f radioactive assay. From the point of view of purification the critical isotopes are 2 y year ^Th in the thorium chain (see Fig. 1) and 1600...

In the present study, we investigate the migration of DNA molecules through a microchannel using a series of electric traps controlled by an ac electric field. We describe the motion of DNA based on Brownian dynamics simulations of a bead-spring chain. The DNA chain captured by an electric field escapes due to thermal fluctuation. The mobility of the DNA chain was determined to depend on the ch...
