Effluents of resin production, petrochemicals, refineries, paper mills, and iron foundry industries may present high concentrations of phenol. The high toxicity, solubility, and stability of phenolic compounds hamper the treatment of this wastewater by conventional methods. In this work, the effect of inorganic ion mixtures, such as chloride, nitrate, sulfate, carbonate, and monophosphate on th...

Cutting tests were conducted to medium carbon steel using HSS tools with cutting fluid. The experimental design used was based on response surface methodology (RSM) using a central composite design. Chips were collected at different machining conditions and thickness and microhardness measurements taken and analyzed using “DESIGN EXPERT 7” experimental design software. Mathematical models of th...

Some mechanical and process parameters of a developed millet thresher have been optimized using numerical optimization technique. The machine threshes panicles cleans the grains from straw. speed threshing number pegs attached to drum were investigated, while moisture content was parameter under investigation. Threshing efficiency, cleaning percentage losses used as performance characteristics ...

Mineral carbonation incurs high operating costs, as large amounts of chemicals and energy must be used in the process. Its implementation on an industrial scale requires reducing expenditures consumption. Thus, this work aimed to investigate significant factors involved pH-swing mineral their effects CO2 capture efficiency. A central composite rotatable design (CCRD) was employed for optimizing...

Chitosan is a biopolymer obtained from shrimp waste mainly by polluting chemical method. In this work, less biological-chemical method to obtain chitosan has been optimized; used successive lactic fermentation and process. Additionally, in the effect of coating on post-harvest behavior fresh-cut papaya was studied as practical application. A rotatable central composite design (CCRD) with two va...

The development of a lactose-free beverage comes as a new feeding alternative to a product with excellent nutritional and functional characteristics to individuals with food restrictions related to milk. Thus, this study aimed to develop a cashew nut beverage with added mango juice and prebiotic substances by means of evaluating its sensory characteristics and physicochemical optimization. A 22...

Friction Stir Welding (FSW) is a solid-state joining process for metals, non-metals and polymers. It carried out with the help of specially designed, non-consumable tool. The heat required, creating softened region at faying surfaces, generated by rotation tool against work piece material. Being welding process, it offers several advantages like inducing minimum effect on mechanical properties ...
