Item Metadata only Unravelling capability of municipal wastewater treatment plant in Thailand for microplastics: Effects of seasonality on detection, fate and transport(2022-01-15) Kittipongvises S.; Phetrak A.; Hongprasith N.; Lohwacharin J.; Mahidol University, and the efficacy of MPs removal by a wastewater treatment plant. The fate and transport of MPs at a WWTP in Nonthaburi, Thailand were tracked during the dry and wet seasons of 2019–2020. Polypropylene (PP), polyethylene (PE), and toothpaste formulations were... the most abundant MP types observed. Total detected MP quantities ranged between 76 and 192 particles L−1 during the dry season, and only 36–68 particles L−1 during the wet season, indicating runoff dilution effects. T-test analysis found a statisticallyPublication Metadata only Application of the AERMOD modeling system for environmental impact assessment of NO 2 emissions from a cement complex(2011-06-01) Kanyanee Seangkiatiyuth; Vanisa Surapipith; Kraichat Tantrakarnapa; Anchaleeporn W. Lothongkum; King Mongkut's Institute of Technology Ladkrabang; Ministry of Natural Resources and Environment; Mahidol University. The dispersion of NO 2 from four cement plants within the selected cement complex were investigated both by measurement and AERMOD simulation in dry and wet seasons. Simulated values of NO 2 emissions were compared with those obtained during a 7-day continuous...-Quantile plots of NO 2 concentrations in dry season were mostly fitted to the middle line compared to those in wet season. This can be attributed to high NO 2 wet deposition. The results show that for both the measurement and the simulation using the AERMODPublication Metadata only Energy use and consumption patterns of maize cultivation-A case study in Thailand(2021-11-01) Sirikarn Thongmai; Thanakrit Neamhom; Withida Patthanaissaranukool; Supawadee Polprasert; Mahidol University; Center of Excellence on Environmental Health and Toxicology (EHT)This study explored energy inputs and consumption patterns to determine energy and economical indices for maize cultivation in Thailand. To assess the energy performance of four used cropping systems, namely, highland cultivation in wet season (HLWS...), highland cultivation in dry season (HLDS), plains cultivation in wet season (PLWS), and plains cultivation in dry season (PLDS), data from energy consumed and produced show Net Energy Value (NEV) gains of +77.0, +106.5, +191.6, and +228.5 GJ/haPublication Metadata only Effect of water and rice straw management practices on yield and water productivity of irrigated lowland rice in the Central Plain of Thailand(2019-01-01) Sumana Maneepitak; Hayat Ullah; Kritkamol Paothong; Boonlue Kachenchart; Avishek Datta; Rajendra P. Shrestha; Faculty of Environment and Resource Studies, Mahidol University; Asian Institute of Technology Thailand; Division of Rice Research and Development© 2018 Elsevier B.V. Rice cultivation techniques with less irrigation water input are crucial for global food security in the context of changing climate scenarios. Alternate wetting and drying (AWD) is among such water-saving techniques, which... after harvest or burned in intensive rice cultivation systems. Response of irrigated lowland rice with respect to grain yield and water use under different water and rice straw management practices largely remains unknown. Field experiments werePublication Metadata only Numerical assessment of PM2.5 and O3 air quality in continental Southeast Asia: Baseline simulation and aerosol direct effects investigation(2019-12-15) Giang Tran Huong Nguyen; Hikari Shimadera; Katsushige Uranishi; Tomohito Matsuo; Akira Kondo; Sarawut Thepanondh; Osaka University; Mahidol University; Dalat University© 2019 Elsevier Ltd An online coupled modeling system composed of Weather Research and Forecasting (WRF) model and Community Multiscale Air Quality (CMAQ) model was applied to assess aerosol direct effects on meteorology and air quality... with the focus on particulate matter with an aerodynamic diameter of 2.5 μm or less (PM2.5) and ozone (O3) in Continental Southeast Asia. Comprehensive model evaluations demonstrated that the modeling system had the capacity to reproduce the observationsItem Metadata only Multiple reservoir optimization using constraint programming for water scarcity resilience in the Chao Phraya River Basin(2026-05-01) Sawangphol W.; Rittima A.; Phankamolsil Y.; Kraisangka J.; Tabucanon A.S.; Talaluxmana Y.; Vudhivanich V.; Sawangphol W.; Mahidol Universityaccomplished by CP models could closely replicate current operation. Moreover, both models could increase the end–of–wet–season storage in the reservoir system by 2,712 and 1,265 MCM/yr, respectively, to potentially supply overplanting during the dry season... deep reinforcement learning, non–linear programming, and adaptive neuro fuzzy inference system in view of increasing the long–term end–of–wet season storage levels of two main storage dams, achieving + 15.73% and + 16.36% for Bhumibol and Sirikit DamsPublication Metadata only Airborne bacteria and fungi distribution characteristics in natural ventilation system of a university hospital in Thailand(2018-05-01) Pawit Chaivisit; Angélique Fontana; Sabine Galindo; Caroline Strub; Thitiworn Choosong; Duangporn Kantachote; Thunwadee Tachapattaworakul Suksaroj; Université de Montpellier; Mahidol University; Prince of Songkla University; Office of Disease Prevention and Control© 2018, Thai Society of Higher Eduation Institutes on Environment.
