We analyze interactions among members of rural communities in Ghana and agriculture development specialists. We find that these participants in the knowledge transfer process are separated by deep knowledge boundaries, as well as by diverging worldviews (one centered on community relations, the other on market relationships). In this context, knowledge transfer is enabled through ritualized int...

The offer of the best machine tool configuration for the specific customer’s need is a decisive factor to compete in the machine tool sector. Actually the offer is organized by the manufacturer mostly on the basis of his own experience and requires a considerable amount of time and money. This effort does not always lead to tangible results, since few offers actually lead to purchases. So there...

In the broadest sense, the application of pesticides involves the transfer of a toxicant from the manufacturer to the target organism. This is the dose transfer process, which can be broken down into several major events. However, difficulties at any step can result in a loss of biological activity, excessive environmental contamination or both. The dose transfer process is a roadmap for the ev...

A mathematical model considering mass and momentum transfer was developed for simulation of ethanol dewatering via pervaporation process. The process involves removal of water from a water/ethanol liquid mixture using a dense polymeric membrane. The model domain was divided into two compartments including feed and membrane. For a description of water transport in ...

Heat exchangers are one of the most important devices of mechanical systems in modernsociety. Most industrial processes involve the transfer of heat and more often they requirethe heat transfer process to be controlled. A heat exchanger is the heat exchanged betweentwo media, one being cold and the other being hot. There are different types of heatexchanger, but the type which is widely used in...

this paper presents the results of a numerical study on the heat transfer performance and the removal process of fluid particles under the influence of magnetohydrodynamic mixed convection in a horizontal channel with an open cavity. the bottom wall of the cavity is heated at a constant temperature (th) while the top wall of the channel is maintained at a relatively low temperature (tc). air wi...

application of therapeutic gene transfer in the treatment of genetic diseases is a notable progress but there are some disadvantages and limitations in it. the process of overcoming these barriers is a drastic change in gene delivery. recently, calcium phosphate nanoparticles alone, or in combination with viral and nonviral vectors, were found to have a positive effect on gene transfer especial...

This paper aims at emphasizing the importance of establishing a Project Management (PM) system in Technology Transfer (TT) processes and developing a conceptual framework for it. TT is an important process in Technology Management affairs for all enterprises.  Most of the time, lack of a particular concentration on technical, commercial and legal aspects of TT process, leads to mismanagement of...

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 ...
