Formation Kinetics of Structure H Gas Hydrate

This paper investigates the kinetics of structure H (sH) formation kinetics above and below the structure I (sI) formation equilibrium curve at temperatures of between 2°C and 6°C. Methane was used as a help gas and methylcyclohexane (MCH) was used as sH former. It was concluded that in the points above the sI formation equilibrium curve, at the first, the sI forms, and then converts to sH be...

The use of a range of technical, symbolic and other means of representation for sensory evaluation contributes to high quality product development in the Food industry. Use of sensory evaluation techniques adapted from industrial practice would contribute to pupils' achievement of higher levels of attainment particularly in Attainment target 3: Planning & Making. Existing educational resources ...

The aim of this paper is to examine which factors in energy systems and the built environment could influence the future of work. In addition, it looks at trends in relation to corporate demands for space and its specifications, and considers what the scope is for integrating business and industry within the dwelling landscape. It seeks to consider these questions on a 50-year time horizon. The...

Prime Chains and Pratt Trees

ABSTRACT. We study the distribution of prime chains, which are sequences p1, . . . , pk of primes for which pj+1 ≡ 1 (mod pj) for each j. We first give conditional upper bounds on the length of Cunningham chains, chains with pj+1 = 2pj+1 for each j. We give estimates for P (x), the number of chains with pk 6 x (k variable), and P (x; p), the number of chains with p1 = p and pk 6 px. The majorit...
