Land cover changes are a prominent driver of environmental changes, impacting various ecosystem components, including soil properties and the dynamics of natural resources, such as the soil particle sizes and the organic carbon stock. The aim of this research study was to define the influence of environmental factors on a set of soil physical and chemical properties (pH, electrical conductivity, bulk density, soil texture, and nitrogen and soil c

For a low-income Cambodian citizen, commuting to and from work is one of the most dangerous parts of their job. In Phnom Penh, the capital city of Cambodia, low-income citizens commute by truck or long-tail remork. This sort of transportation would be dangerous on the road. Thousands of workers get to and from work every day in vans, but this massive transportation system is almost completely unregulated. Most of the drivers are independent contr

The growing number of battery technologies and increasing environmental concerns have accelerated the transition to electric vehicles. As internal combustion engine vehicles are replaced by EVs, the impact of EV charging loads on power system operations has become a significant concern. However, the growing adoption of electric vehicles (EVs) presents a challenge for power grids that cannot be neglected. The high charging loads, particularly from

Most medium voltage (MV) distribution systems are structured in mesh and radially operated to distribute electric power from distribution substations to consumers (distribution transformers). The difficult decision of building a new radial MV topology is which branch should be connected to others and could save cost in constructing for the operator in the first stage of designing and bidding for the new topology. Due to that problem which always

In many companies and organizations around the world, user’s identity data is stored and handled in centralized systems rather than decentralized ones. A centralized system comes with many risks, such as data leaks or users not being in control of their data. These problems can be fixed by using a decentralized system known as the Self-Sovereign Identity (SSI) system. SSI system is a user-centric system that lets users manage and control their ow

Soy sauce is a brown liquid and widely used as a seasoning in East Asia, and its popularity in the Western part of the world is growing due to its unique taste and aroma. The black soy sauce is used to flavor dishes, but more importantly, it is used to darken the color of sauces, fried rice and noodles. In Cambodia, there are only local light soy sauces and there is no black soy sauce produced locally. Therefore, the purpose of this study was to

This study explored the transformation of cassava peels (Manihot esculenta) into activated carbon via chemical activation with phosphoric acid, and investigated by varying impregnation ratios and temperatures to optimize adsorption efficiency for diclofenac removal. It examined the feasibility of using cassava peels as precursors for activated carbon specifically for diclofenac removal. Cassava peels were impregnated with phosphoric acid at a ra

Characterized by a predominantly agricultural landscape, including rice paddy, agricultural land, and scattered forest, the Chrey Bak catchment of the Tonle Sap Lake, Cambodia, is experiencing challenges such as deforestation and land conversion, which negatively impact mineral alteration sources, land management, and ecosystems. The current study uses satellite data (Sentinel 2, Landsat-8 OLI, and ASTER) to detect changes in mineral alteration (

Smoking is the most widely practiced method applied practically for all species of fish. Smoking is a technique for preserving fish that has been processed with organic components derived from smoke. Smoke produces volatile fragrant compounds that impart specific properties to fish flesh. Fish smoking commonly takes place in conventional kilns with direct burning of wood, sawdust, coconut shell and coal combustion at high temperatures. The heat bur

This study aims to analyze the differences of each satellite product and their responses between the dry and rainy seasons by investigating seasonal floods and spectral indices based on Hierarchical Split-Based Approach (HBSA) from Sentinel-1and Sentienl-2 imagery, respectively, together with Climate Hazards group Infrared Precipitation with Stations (CHIRPS) precipitation data. The spectral indices calculated from Sentinel-2 images at different
