In recent years, the CubeSat project has become a useful tool to teach university students about space engineering. Getting started with the CubeSat is still a barrier to educational institutions that are new to space technology. Having a satellite training kit to teach students about satellite is an effective approach. This paper provides a design process of the Electrical Power Subsystem (EPS) of the educational satellite training tool in the f

Traffic congestion and traffic accident have been a serious and significant problem in Phnom Penh city because the population has increased every year. An insufficient traffic signal, non-standard geometry, driver behavior, and lack of traffic discipline are the main factors that affect traffic flow. Kdan Pir is a very important intersection that has connected between Khan 7 Makara and Khan Toul Kork. Many people are crossing this intersection. T

Traffic congestion has become a serious problem in many Asian developing cities; there is no exception for Phnom Penh. As urban areas continue to expand, more roads and intersections are built to accommodate the increasing traffic. The poor design of an intersection and traffic signal could be the roots of interrupting traffic flow and creating traffic conflicting areas which increasing traffic congestions in the city. In particular, one of the w

Tonle Sap lake has been the largest fresh water lake in Southeast Asia, providing a fundamental environment for nurturing more than three million people in the five surrounding provinces, which about 90% lived from the fishery or agriculture. However, the ecosystem and populations living around the lake have experienced environmental pressure, since the lake water, fishes, living organisms are polluted. More than that, sediment is the type of soi

Pesticide residues in surface water, sediment and fish samples from Chnok Tru Floating Community of Tonle Sap Lake (TSL) was determined. Surface water and sediments from 18 sites were collected while 10 fish species were sampled from different locations of Chhnok Tru Floating Village. Samples were extracted by solid-phase extraction method using PLS3-AC2 cartridge and were subjected to analysis by GC-MS with an automated identification and quanti

Assessing the characteristic of soil properties is important for various purposes, especially for agriculture. The spatial distribution mapping for soil properties in Chrey Bak Catchment can be generated by geospatial analyst (Ordinary Kriging) methods with different semivariogram models: Gaussian model, Exponential model, Pentaspherical model and Hole effect model. The objectives of this study are to: (i) compare and evaluate the most accurate i

This study aims to assess flow regime alterations under climate change scenarios in the Stung Chinit river basin, one among tributaries of the Tonle Sap Great Lake, Cambodia. Five bias-collected regional climate models (RCMs) under RCP4.5 and RCP8.5 using quantile mapping technique were employed into the Soil and Water Assessment Tool (SWAT) model to quantify changes in future hydrologic characteristic. Three future time horizons —the 2020s, 2050

Understanding the aquifer hydraulic properties and hydrochemical characteristics of water are crucial for the management plan and study skims in Cambodia, where groundwater has been used for domestic and agricultural purposes in the rural area. In this study, there are two times observed well during late wet season October 2017 and early wet season May 2018. Water Quality Index (WQI) was use to assess of groundwater for drinking and SAR, KR, SSP,

In Cambodia, rice liquors or Sra Sor is locally produced in large amounts every year. This traditional beverage is made from the combination of rice starch with different traditional starters consisting of molds and fermenting yeast. Recently, the quality and the ethanol yield of rice wine produced by traditional starter were notably low. Thus, the utmost concern is to improve the quality of the product in terms of physicochemical and sensory pro

The study was carried out on detection of Enterococcus spp. in fermented and pickled vegetable products from markets in Phnom Penh and determination of their antibiotic resistance. Thirty-nine samples were collected from six different sites and classified into six categories of fermented and pickled vegetable products. Samples were subjected to physicochemical and microbiological analysis, followed by isolation and antibiotic susceptibility test
