Complex heat transfer phenomena (including unsteady state conduction, convection and solidification processes) occur in steel belt conveyer sulfur granulating method. Numerical simulation of this technique is performed via a comprehensive and multifaceted one dimensional model. Since the air situated between the adjacent sulfur pastilles is essentially stagnant, therefore, the surface tempe...

the main objective of this paper is to examine the effect of nanomaterials on mass transfer coefficient in bubble type absorption of carbon dioxide by experiment. the absorption process is carried out in a bubble column and in room temperature. mass transfer coefficient, saturated concentration of co2, and gas holdup are determined in this system. the kinds of nanomaterials, the concentrations ...

The learning objectives of this presentation are to understand the dynamics involved in the process of ET, evaluate the evidence for/against common practices and techniques and develop a standardized ET process in view of supporting evidence. Gametes and embryos are handled with extreme care at every step of the Laboratory process. ET is the least sophisticated step of the in vitro Fertilizatio...

In order to examine the laminar convective heat transfer of nanofluid, experiments carried out using silver-oil nanofluid in a concentric annulus with outer constant heat flux as boundary condition. Silver-oil nanofluid prepared by Electrical Explosion of Wire technique and observed no nanoparticles agglomeration during nanofluid preparation process and carried out experiments. The average size...

We illustrate the energy transfer during planetary flybys as a function of time using a number of flight mission examples. The energy transfer process is rather more complicated than a monotonic increase (or decrease) of energy with time. It exhibits temporary maxima and minima with time which then partially moderate before the asymptotic condition is obtained. The energy transfer to angular mo...

Transfer function modeling is a standard technique in classical Linear Time Invariant and Statistical Process Control. The work of Box and Jenkins was seminal in developing methods for identifying parameters associated with classical (r, s, k) transfer functions. Computing systems are often fundamentally discrete and feedback control in these situations may require discrete event systems for mo...

Proton transfer into and out of proteins is important, both for many enzyme reaction mechanisms and proton pumping across membranes. Recent work on several proteins has revealed stringent requirements for amino-acid side chains and subtle reorganisation of hydrogen-bond networks involving bound water molecules.

Received: 26 May 2006 Revised: 16 May 2007 Accepted: 30 July 2007 Online publication date: 29 May 2008 Abstract Because of the strategic importance of organizational learning in a global economy, the knowledge that repatriates acquire during international assignments is a valuable resource. Few multinational enterprises, however, actively harvest this knowledge, and little quantitative empirica...

We have studied numerically the statistical mechanics of the dynamic phenomena, including money circulation and economic mobility, in some transfer models. The models on which our investigations were performed are the basic model proposed by A. Drăgulescu and V. Yakovenko [1], the model with uniform saving rate developed by A. Chakraborti and B.K. Chakrabarti [2], and its extended model with di...
