Summary: This research focuses on refining plant fibre, especially wood fibre, in a disc refiner by modifying disc design to regulate forces for improved efficiency in the refining process. Experimental studies on softwood fibre refining determined optimal process conditions and dependencies for regulating gap between refiner discs and pulp concentration. The new disc design ensures more intense fiber diameter reduction, leading to better inter-fiber interaction and improved strength properties in finished products without the use of binding resins.

Summary: This study compared the influence of direct and alternating current on the electrocoagulation process for color and COD removal in distillery industrial effluent. The results showed that the Alternating Current Electrocoagulation (ACE) process was more successful in removing color and COD with less electrical energy consumption compared to Direct Current Electrocoagulation (DCE).

Summary: This study aimed to investigate the proportion of pwMS who achieve the maximal oxygen consumption criteria and to identify participant characteristics that limit maximal exercise performance. The findings showed that only 60% of the participants met the criteria for respiratory exchange ratio = 1.10, and a smaller percentage achieved the criteria for oxygen consumption plateau or heart rate. Disability status, gender, disease course, and body mass index were associated with the attainment of maximal effort.

Summary: This paper explores the concept of hybrid manufacturing (HM), specifically focusing on the widely-adopted hybrid additive-subtractive manufacturing. The study investigates the potential of HM to improve productivity and manufacturability from a process planning perspective. A new set of decision criteria and an optimization model are introduced, and an efficient optimization algorithm using genetic algorithm is proposed. Experimental results show that the integration of additive and subtractive processes in HM can overcome the limitations of conventional manufacturing, reducing manufacturing cost and time significantly for multiple test cases.

Summary: It is common to ignore volume changes in numerical simulations of food drying, leading to lower accuracy. This study develops a three-dimensional model that incorporates volume changes and considers the asymmetry of shrinkage. Experimental data on fruit drying kinetics and asymmetric shrinkage mode support the model's effectiveness, reducing the relative error by over 4 times compared to simulations without volume changes. This proposed model proves to be a useful method for more accurate modeling of drying processes.

Summary: In this study, a two-stage clustering-based energy consumption evaluation method is proposed for process industries. A novel structure of the fuzzy clustering method is designed with a mixture of unsupervised and semi-supervised learning stages to independently address energy consumption patterns. Energy consumption predictions are estimated for potential energy-optimized control. The method delivers better evaluation results against baselines and provides a new thought for energy consumption evaluation.

Summary: This study examines the relationship between disaggregated energy use, economic growth, and environmental quality in Saudi Arabia using machine learning techniques. It finds that reducing CO2 emissions requires a complete transition from fossil to renewable resources and a more viable road to sustainability. The study also predicts that CO2 emissions will continue to grow until 2024, and afterwards, a decrease in emissions must be accompanied by an increase in renewable energy use to ensure stable economic growth.
