paradox of flow in the realm of education and schooling. Although there is much potential for flow experiences in schools‚ there tends to be a relatively small amount of flow experiences in educational settings‚ especially in academic classes. The author of this article attempts to find the reason for the lack of flow in the classroom‚ thereby enabling educators to address this problem and increase the number of flow experiences in their classes. Numerous conditions and precursors to flow are available

Abrasive flow machining 1. Introduction Abrasive flow machining (AFM) was firstly developed fifty years ago by Extrude Hone Corporation‚ USA. By using the liquid viscoelastic material with easy flowability made of polymer and abrasive grains‚ AFM can be used to polish‚ deburr and radius for the workpiece. There are three kinds of AFM: one-way AFM‚ two-way AFM and orbital AFM [1]. In this case to manufacture the cylinder heads‚ consider of two-way AFM is much more widely used and its technology

Experiment 3 Method of Flow Measurement Objective To demonstrate typical flow measurement devices for incompressible fluids: (1) venturi meter‚ (2) orifice plate and (3) rotameter. To compare the difference in flow rate incurred by each of these device. Overview In engineering and industrial practice‚ fluid measurement of many of the variables and properties‚ such as density‚ viscosity‚ pressure‚ velocity‚ flow rate and etc is one of the problems most frequently encountered by engineers

Free Flow Layout Free flow layout is an irregular arrangement of retail setting that encourages a formless traffic flow. It is mainly used in stores which have wide range of products. Easy to navigate and display to another were one of the major characteristics of free flow layout. Compare to the other retail layout‚ free flow layout had no particular display pattern. All the fixtures and products were grouped and located in flowing patterns on the sales floor. This layout usually used in stores

The circular flow of income model is a theoretical representation of the economy. It shows the distribution of income within the economy and the interaction between the different sectors in a modern market economy. The five-sector model is a more elaborate model in comparison to the basic‚ two‚ three and four sector models. The model represents an economy like Australia and divides the economy into five main sectors. The first sector in the model is the Households sector. This sector refers to

In economics‚ the terms circular flow of income or circular flowrefer to a simple economic model which describes the reciprocal circulation of income between producers and consumers.[1][2] In the circular flow model‚ the inter-dependent entities of producer and consumer are referred to as "firms" and "households" respectively and provide each other with factors in order to facilitate the flow of income.[1] Firms provide consumers with goods and services in exchange for consumer expenditure and "factors

1. Experimental Methods The aims of this experiment to determine the rate of the reaction by using tubular flow reactor data‚ to demonstrate the temperature dependence of the reaction and also the rate constant and to observe the effect of different flow rates to the conversion. It is a homogenous reaction with only liquid phase is present. Also the reaction is endothermic. The saponification reaction is as follows; NaOH + EtOAc NaOAc + EtOH The reactants were taken as 1:1 ratios. 0.1 M NaOH
