A Finite Element Simulation of the Active and Passive Controls of the MHD Effect on an Axisymmetric Nanofluid Flow with Thermo-Diffusion over a Radially Stretched Sheet
Processes - Tập 8 Số 2 - Trang 207
Bagh Ali, Xiaojun Yu, Muhammad Tariq Sadiq, Ateeq Ur Rehman, Liaqat Ali
The present study investigated the steady magnetohydrodynamics of the axisymmetric flow of a incompressible, viscous, electricity-conducting nanofluid with convective boundary conditions and thermo-diffusion over a radially stretched surface. The nanoparticles’ volume fraction was passively controlled on the boundary, rather than actively controlled. The governing non-linear partial differ...... hiện toàn bộ
Natural Convection and Entropy Generation of MgO/Water Nanofluids in the Enclosure under a Magnetic Field and Radiation Effects
Processes - Tập 9 Số 8 - Trang 1277
Yacine Khetib, Ahmad Aziz Alahmadi, Ali Alzaed, Ahamd Tahmasebi, Mohsen Sharifpur, Goshtasp Cheraghian
The authors of the present paper sought to conduct a numerical study on the convection heat transfer, along with the radiation and entropy generation (EGE) of a nanofluids (NFs) in a two and three-dimensional square enclosure, by using the FVM. The enclosure contained a high-temperature blade in the form of a vertical elliptical quadrant in the lower corner of the enclosure. The right edge...... hiện toàn bộ
Monitoring Parallel Robotic Cultivations with Online Multivariate Analysis
Processes - Tập 8 Số 5 - Trang 582
Sebastian Groß, Christian Ulmer, Harini Narayanan, Trygve Brautaset, Niels Krausch, Peter Neubauer, Irmgard Schäffl, Michael Sokolov, Mariano Nicolás Cruz Bournazou
In conditional microbial screening, a limited number of candidate strains are tested at different conditions searching for the optimal operation strategy in production (e.g., temperature and pH shifts, media composition as well as feeding and induction strategies). To achieve this, cultivation volumes of >10 mL and advanced control schemes are required to allow appropriate sampling and ...... hiện toàn bộ
Relationship Between MiRKAT and Coefficient of Determination in Similarity Matrix Regression
Processes - Tập 7 Số 2 - Trang 79
Xiang Zhan
The Microbiome Regression-based Kernel Association Test (MiRKAT) is widely used in testing for the association between microbiome compositions and an outcome of interest. The MiRKAT statistic is derived as a variance-component score test in a kernel machine regression-based generalized linear mixed model. In this brief report, we show that the MiRKAT statistic is proportional to the R ...... hiện toàn bộ
Aeration Process in Bioreactors as the Main Energy Consumer in a Wastewater Treatment Plant. Review of Solutions and Methods of Process Optimization
Processes - Tập 7 Số 5 - Trang 311
Jakub Drewnowski, Anna Remiszewska-Skwarek, Sylwia Duda, Grzegorz Łagód
Due to the key role of the biological decomposition process of organic compounds in wastewater treatment, a very important thing is appropriate aeration of activated sludge, because microorganisms have to be supplied with an appropriate amount of oxygen. Aeration is one of the most energy-consuming processes in the conventional activated sludge systems of wastewater treatment technology (m...... hiện toàn bộ
Food Waste Composting and Microbial Community Structure Profiling
Processes - Tập 8 Số 6 - Trang 723
Kishneth Palaniveloo, Muhammad Azri Amran, Nur Azeyanti Norhashim, Nuradilla Mohamad‐Fauzi, Fang Peng-Hui, Low Hui-Wen, Yap Kai-Lin, Looi Jiale, Melissa Goh Chian-Yee, Lai Jing-Yi, Baskaran Gunasekaran, Shariza Abdul Razak
Over the last decade, food waste has been one of the major issues globally as it brings a negative impact on the environment and health. Rotting discharges methane, causing greenhouse effect and adverse health effects due to pathogenic microorganisms or toxic leachates that reach agricultural land and water system. As a solution, composting is implemented to manage and reduce food waste in...... hiện toàn bộ
Modeling the Biosorption Process of Heavy Metal Ions on Soybean-Based Low-Cost Biosorbents Using Artificial Neural Networks
Processes - Tập 10 Số 3 - Trang 603
Daniela Ionela Ferţu, Elena-Niculina Drăgoi, Laura Bulgariu, Silvia Curteanu, Maria Gavrilescu
Pollution of the environment with heavy metals requires finding solutions to eliminate them from aqueous flows. The current trends aim at exploiting the advantages of the adsorption operation, by using some low-cost sorbents from agricultural waste biomass, and with good retention capacity of some heavy metal ions. In this context, it is important to provide tools that allow the modeling a...... hiện toàn bộ
Fucosylated Chondroitin Sulfate from Bohadschia ocellata: Structure Analysis and Bioactivities
Processes - Tập 12 Số 10 - Trang 2108 - 2024
Thinh, Pham Duc, Cao, Hang Thi Thuy, Trung, Dinh Thanh, Minh, Duong Khanh, Cao, Thao Quyen, Van, Tran Thi Thanh, Zueva, Anastasia O., Ermakova, Svetlana P., Nguyen, Thanh-Danh
Fucosylated chondroitin sulfate (FCS) was prepared from Bohadschia ocellata using protease hydrolysis. The structural characteristics of FCS were confirmed through chemical composition analysis using FTIR spectroscopy, 1H NMR, and 13C NMR. FCS from B. ocellata (FCS-Bo) exhibited an average molecular weight of approximately 122 kDa. The biological activities of FCS-Bo, including anticoagulant, anti...... hiện toàn bộ
Technology for the Remediation of Water Pollution: A Review on the Fabrication of Metal Organic Frameworks
Processes - Tập 6 Số 8 - Trang 122
Yongning Bian, Nana Xiong, Guocheng Zhu
The ineffective control of the release of pollutants into water has led to serious water pollution. Compared with conditions in the past, the polluting components in aquatic environments have become increasingly complex. Some emerging substances have led to a new threat to the safety of water. Therefore, developing cost-effective technologies for the remediation of water pollution is urgen...... hiện toàn bộ
Evaluation of Water Hammer for Seawater Treatment System in Offshore Floating Production Unit
Processes - Tập 8 Số 9 - Trang 1041
Joon Seong Park, Quang Khai Nguyen, Gang Nam Lee, Kwang Hyo Jung, Hyun Park, Sung-Bu Suh
Water hammer can result in the rupture of pipes, and significant damage to pipe supports is inevitable during the operation of an offshore plant. In this study, the dynamic behaviors of the water hammer caused by closing valves and starting pumps for the seawater treatment system were evaluated by using the 1D numerical simulation model based on the method of characteristics. Before conduc...... hiện toàn bộ
