Item Metadata only Business process reengineering by Sap Best Practice (make to order) : case study process of sales for industrual production of copper(Mahidol University. Mahidol University Library and Knowledge Center, 2014) Kittipong Thammaluksasit; Supaporn Kiattisin; Adisorn LeelasantithamThe problems of the sales process for this case study of Industrial Production of Copper are that sales processes are duplicated and use a lot of paper within the customer and sales department. Therefore, Industrial Production of Copper would like... to implement the SAP system to fix the problem of the sales process. However the SAP system is costly to implement. Therefore, Industrial Production of Copper would like to redesign the business process of sales using BPR (Business Process Reengineering) firstItem Metadata only Appropriate method for solving scale problem in shell and tube heat exchanger(Mahidol University. Mahidol University Library and Knowledge Center, 2024) Sarun Seubkrasair; Eakkachai Warinsiriruk; Noppakorn Phuraya; Sira Sriniveswas used to prevent formation of clay particle in copper tube. The study found that the copper tube that was supplied a positive electric charge resulted in a large amount of clay particle being attracted, while the copper tube that was supplied a negative... electric charge has less clay particle. The results showed that an increase in voltage or water flow rate would result in an increased amount of clay particle formation. However, the electrical supply directly to the copper tube will cause corrosionItem Metadata only Photocatalytic conversion of Carbon Dioxide to Alcohols over Titanium dioxide-graphene composite(Mahidol University. Mahidol University Library and Knowledge Center, 2024) Krittamet Yanawibut; Pattaraporn Kim-Lohsoontorn; Sira SrinivesPhoto-catalyst comprising titanium dioxide-reduced graphene oxide (TiO2/rGO) and copper(II)oxide-titanium dioxide-reduced graphene oxide (CuO-TiO2/rGO) were developed for CO2 conversion to ethanol. The effects of TiO2 (10-60 wt%)and CuO contents (0
