This paper presents Gene-Expression Programming (GEP), which is an extension to the genetic programming (GP) approach to predict the total bed material load for three Malaysian rivers. The GEP is employed without any restriction to an extensive database compiled from measurements in the Muda, Langat, and Kurau rivers. The GEP approach demonstrated a superior performance compared to other traditional sediment load methods. The coefficient of determination, R-2 (= 0.97) and the mean square error, MSE (= 0.057) of the GEP method are higher than those of the traditional method. The performance of the GEP method demonstrates its predictive capability and the possibility of the generalization of the model to nonlinear problems for river engineering applications.

Mathematical simulation of air-water flow along Ski Jump Jet

Roghayeh Ahmadpour, Hamed Sarkardeh, Hazi Azamathulla

Summary: The study examines the air concentration distribution in ski jump generated jet using quasi 3D analytical simulation and numerical analysis, confirming a unique relationship between air concentrations and relative black water core length. Various factors such as approach flow depth, Froude number, and geometrical parameters of ski jump influence the black water core length and the air concentration distribution along the jet. An analytical equation is proposed to predict air concentration distribution based on different hydraulic and geometric parameters, and increasing air concentration is found to reduce the jet velocity profile.

Kiyoumars Roushangar, Roghayeh Ghasempour, Hazi Mohammad Azamathulla

Summary: In this research, a finite difference scheme developed by Richtmeyer is presented for simulating 1D steady/unsteady flow and bed morphology in alluvial channels. Laboratory experiments were conducted to validate the proposed model. The role of sediment transport formulas, coupled uncoupled approaches, and simplification in the mass continuity equation are investigated for improving the simulation. The study also highlights the importance of changing alluvial roughness and the application of a genetic algorithm in optimizing roughness coefficients.

Carboxymethyl cellulose/sodium alginate beads incorporated with calcium carbonate nanoparticles and bentonite for phosphate recovery

Jialin Fu, Jia Xin Yap, Choe Peng Leo, Chun Kiat Chang

Summary: In this study, carboxymethyl cellulose (CMC)/sodium alginate (SA) hydrogel beads were modified with calcium carbonate (CaCO3) and/or bentonite (Be) to improve phosphate adsorption. Incorporation of CaCO3 nanoparticles into CMC/SA/Be hydrogel beads significantly enhanced phosphate adsorption. The kinetics of methylene blue (MB) adsorption by hydrogel beads followed the pseudo-second-order model, while phosphate adsorption followed the Elovich model. Furthermore, Langmuir isotherm fitted the phosphate adsorption by CMC/SA/Be/CaCO3 hydrogel beads, indicating improved phosphate adsorption through chemical interaction.

Summary: This study evaluates the capabilities of three global precipitation measurement (GPM) integrated multisatellite retrievals for GPM (IMERG) products in tropical flood hazard mapping in the Kelantan River Basin (KRB), Malaysia, using GIS-based analytic hierarchy process (AHP) method. The results showed that the IMERG products performed well in generating flood hazard maps, with the majority of historical floods occurring in moderate-to-very-high flood hazard areas. The middle and lower parts of the KRB were identified as regions of very high and high hazard levels that require particular attention from local stakeholders.

Polysaccharide Hydrogels for Controlling the Nutrient Release

Jialin Fu, Jia Xin Yap, C. P. Leo, Chun Kiat Chang, Pau-Loke Show

Summary: This review compares the loading and release of different nutrients from polysaccharide hydrogels for fertilizing purposes. Various methods were studied to control the release of urea, nitrogen sources, phosphate, and potassium from the hydrogels. However, most of the polysaccharide hydrogels did not meet the nutrient release standards. Additionally, utilizing polysaccharide-rich waste and nutrients in wastewater can further reduce the cost.

Performance of a right-triangle stilling basin: a laboratory investigation

Asma Rabiei, Jahanshir Mohammadzadeh-Habili, Aaron Anil Chadee, Seyed Mohammadali Zomorodian, Mohammad Jameel, Hazi Mohammad Azamathulla

Summary: The hydraulic jump stilling basin is commonly used for dissipating energy from supercritical flow. A mathematical relationship between the sequent flow depth ratio of a hydraulic jump and the inflow Froude number and relative length of the basin front was derived through dimensional analysis. The proposed structure stabilized the hydraulic jump and improved energy dissipation performance. Experimental and numerical simulations showed the formation of large recirculation regions, leading to intense energy dissipation in the right-triangle basin.

Summary: Recent research has been primarily focused on the introduction, development, and evaluation of performance-based specifications for asphalt concrete mixture design. In the Caribbean, most laboratories solely use the Volumetric Marshall Mix design methodology, which has been criticized for its limitations. Performance-Based Mix Design (PBMD) has emerged as an alternative approach that incorporates performance testing alongside volumetric parameters. This study presents the findings of comprehensive laboratory research aimed at developing a PBMD framework for asphalt concrete mixtures.

An advanced global soil erodibility (K) assessment including the effects of saturated hydraulic conductivity

Surya Gupta, Pasquale Borrelli, Panos Panagos, Christine Alewell

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: The choice of workflow in wastewater surveillance has a significant impact on SARS-CoV-2 concentrations, while having minimal effects on HF183 and no effect on HAdV 40/41 concentrations. Certain components in the workflow can be interchangeable, but factors such as buffer type, chloroform, and homogenization speed can affect the recovery of viruses and bacteria.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
