A novel method for extraction of alumina from red mud using a divalent alkaline earth metal oxide soda ash sinter process followed by thermo chemical leaching in suitable caustic concentration at 105°C for different times is presented in this paper. During sintering Sodalite/Cancrinite, Gibbsite and Boehmite in red mud is converted to sodium aluminate as well as stable phases of divalent alkaline earth metal ferrite, titanate and silicate. In the above novel economic process an extraction of alumina from red mud of 97.64%, 98.7% and 99.5% was achieved using CaO, MgO and BaO respectively. The morphological study of sinter products and leached products was studied using SEM and XRD.

A new chemical technology that addresses the deficiencies of the Sapphire treatment has been reported. Advertisers and other mass media outlets are constantly striving to enhance their methods for attracting customers to their product. The HP Indigo digital printing process is a direct-to-plate printing process that utilizes both electro-photographic and offset printing techniques. The size press was surveyed to ensure that it was mechanically well suited to the application of DIAMOND™ DIGITAL technology. Equipment to make up batches of size press solution containing the DIAMOND™ DIGITAL technology was available on site with agitation and steam heating. The Electroink® adhesion was significantly improved with the DIAMOND™ DIGITAL technology. A new Digital grade of paper has been successfully launched called Saxton Smooth Digital.

In the context of day-ahead or real-time electricity prices, the method of economic model predictive control has been shown to provide expenditure reduction in building HVAC systems, specifically if coupled with active thermal energy storage. However, due to the diurnal nature of electricity prices, these expenditure reductions can only be achieved if the economic model predictive control prediction horizon is sufficiently large, typically greater than 12 h. This work develops an alternative controller known as constrained economic linear optimal control. This constrained economic linear optimal control policy is shown to yield economic performance similar to a large-horizon economic model predictive control policy but also possesses a virtual insensitivity to horizon size. Thus, application of the constrained economic linear optimal control policy will require a fraction of the computational effort while yielding nearly identical economic performance. ©2015 ASHRAE.

The usage of M-commerce (Mobile commerce) is growing in businesses. There are some important issues need to be addressed in M-commerce, such as integrating the function of business intelligence and information system management to m-commence, applying businesses process management into M-commerce. This study attempts to investigate some of those m-commerce issues. The empirical data is used to exam the usage of business intelligence in M-commerce, and whether the use of M-commerce would help improve business processes.

It is well understood that environmentally-friendly production chemicals are required in the oilfield production industry, particularly in regions such as the North Sea where environmental criteria for application is considered to be the global standard. Efforts are now underway to phase-out substances in the North Sea based on persistency, bioaccumulation, and toxicity (PBT) properties of the chemicals as per a defined set of guidelines and level of priority. Replacement production chemicals which meet environmental criteria for numerous applications are seen as high priority for chemical suppliers and producers alike. An on-going research effort in the development of high performance green corrosion inhibitors has been underway for these challenging systems which suffer not only from high temperatures and pressures, but also high shear. This work will detail the development process and field application of a new chemistry designed specifically to replace an incumbent product affected by the 2012 Level 2 UK National Plan criteria. The work outlines the systematic studies of corrosion inhibition under conditions of high pressure, high temperature, and high shear, improvement in emulsion tendency and separation, and optimization of key active components with improved environmental fate for overboard discharge. © 2013 by NACE International.
