TL;DR: It is found that cation addition did not significantly enhance the flocculating rate and IH-7 is a positively charged bioflocculant, suggesting that charge neutralization is the main flocculation mechanism of Ih-7 biofloccculant.

TL;DR: The new developed AMR-IBM algorithm is validated using a benchmark data of fluid past a cylinder and the results show that there is good agreement under laminar flow, confirming the robustness of the new algorithms in simulating flow characteristics in the boundary layers of thin structures.
Abstract: This study aims to develop an adaptive mesh refinement (AMR) algorithm combined with Cut-Cell IBM using two-stage pressure–velocity corrections for thin-object FSI problems. To achieve the objectiv ...

TL;DR: In this article, the authors presented the life cycle assessment (LCA) of waste cooking oil biodiesel production catalyzed by waste chicken eggshell derived CaO catalyst to validate the suitability of waste chicken shell as a green catalyst in biodiesel field.
Abstract: There are plentiful experimental studies on biomass as heterogeneous catalyst and its reasonable cost, it can be a potential catalyst feedstock for biodiesel production. This study presents the life cycle assessment (LCA) of waste cooking oil biodiesel production catalyzed by waste chicken eggshell derived CaO catalyst to validate the suitability of waste chicken eggshell as a green catalyst in biodiesel field. To the best of our knowledge, LCA was first performed for the heterogeneous catalyst, CaO preparation as a subsystem in a biodiesel production. Comparative studies were performed to evaluate the difference of environmental impacts contributed by waste cooking oil, WCO biodiesel production catalyzed by waste chicken eggshell derived CaO with the two different production processes via Jatropha oil as the oil feedstock and potassium hydroxide, KOH as the homogeneous catalyst. Utilization of WCO as the oil feedstock for biodiesel production has lesser environment impact than the Jatropha oil as the WCO biodiesel production does not involve agriculture phase. Likewise, utilization of waste chicken eggshell derived CaO catalyst (heterogeneous catalyst) has less contribution on the overall impact categories than KOH (homogeneous alkali-based catalyst) as the production of KOH required addition of chemical and additives, plus complex purification and neutralization processes are required during the production phase. The overall impact results clearly indicated the best environmental performance of waste chicken eggshell derived CaO of 1.17 Pt was over the traditional KOH catalyst and implementation of Jatropha oil but also identified some bottlenecks that should be addressed for more sustainable solutions.

TL;DR: 6 heuristic algorithms are studied: Nearest Neighbor, Genetic Algorithm, Simulated Annealing, Tabu Search, Ant Colony Optimization and Tree Physiology Optimization for Travelling Salesman Problem.
Abstract: The Travelling Salesman Problem (TSP) is an NP-hard problem with high number of possible solutions. The complexity increases with the factorial of n nodes in each specific problem. Meta-heuristic algorithms are an optimization algorithm that able to solve TSP problem towards a satisfactory solution. To date, there are many meta-heuristic algorithms introduced in literatures which consist of different philosophies of intensification and diversification. This paper focuses on 6 heuristic algorithms: Nearest Neighbor, Genetic Algorithm, Simulated Annealing, Tabu Search, Ant Colony Optimization and Tree Physiology Optimization. The study in this paper includes comparison of computation, accuracy and convergence.
