Publication Open Access Paper-based Acetylcholinesterase Inhibition Assay Combining a Wet System for Organophosphate and Carbamate Pesticides Detection(2015-02-26) Amara Apilux; Chartchalerm Isarankura-Na-Ayudhya; Virapong Prachayasittikul; Tanawut Tantimongcolwat; Center for Innovation Development and Technology Transfer; Department of Clinical Microbiology and Applied TechnologyA dramatic increase in pesticide usage in agriculture highlights the need for on-site monitoring for public health and safety. Here, a paper-based sensor combined with a wet system was developed for the simple and rapid screeningPublication Metadata only Paper-based acetylcholinesterase inhibition assay combining a wet system for organophosphate and carbamate pesticides detection(2015-01-01) Amara Apilux; Chartchalerm Isarankura Na Ayudhya; Tanawut Tantimongcolwat; Virapong Prachayasittikul; Mahidol Universitycombined with a wet system was developed for the simple and rapid screening of organophosphate (OP) and carbamate (CM) pesticides based on the inhibition of acetylcholinesterase (AChE). The paper-based sensor was designed as a foldable device consistingItem 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 AERMODItem Metadata only Comparative assessment of groundwater recharge estimation using physicalbased models and empirical methods in Upper Greater Mae Klong Irrigation Project, Thailand(2022-07-01) Phankamolsil Y.; Rittima A.; Teerapunyapong P.; Surakit K.; Tabucanon A.S.; Sawangphol W.; Kraisangka J.; Talaluxmana Y.; Vudhivanich V.; Mahidol Universityin the Upper Greater Mae Klong Irrigation Project. Materials & Methods: Two physical-based models (WetSpass and SWAP) were used to estimate groundwater recharge and the outcomes were compared with the results from empirical and water balance-based methods.... Groundwater recharge modelling was investigated based on model type, data requirements, model complexity, model adaptability and model performance. Results: The average annual recharges estimated using the WetSpass and SWAP models were 183.59 mm/yr and 133Item Metadata only Business plan for wet wipe for mobile phones and devices(Mahidol University. Mahidol University Library and Knowledge Center, 2024) Ausanisa Kaewsringam; Dissatat Prasertsakul; Thanarerk Thanakijsombatare accumulated. Research stated that they can weaken the immune system, while the common effects are producing pimples and causing diarrhea. With the currently available cleaning tools, it is still inconvenient for people to use. Therefore, the idea of creating a... wet wipe for smartphones and devices has been found. Wet wipe for smartphones and devices, Cleani, is emphasizing its formula and design to fulfill the basic function of cleaning effectively yet easier to use. Based on 400 responses, the product wouldPublication Metadata only Effects of Blend Ratio and SBR Type on Properties of Carbon Black-Filled and Silica-Filled SBR/BR Tire Tread Compounds(2017-01-01) Pongdhorn Sae-Oui; Krisda Suchiva; Chakrit Sirisinha; Wenussarin Intiya; Pram Yodjun; Uthai Thepsuwan; Thailand National Science and Technology Development Agency; Mahidol Universityproperties (tire performance) compared to E-SBR, particularly obvious in the silica-filled system. Compared with CB, silica gave comparable strengths, better wet grip efficiency, and lower rolling resistance. Carbon black, however, offered greater abrasion... of these parameters on properties of the tread compounds reinforced by 80 parts per hundred rubber (phr) of carbon black (CB) and silica were also compared. Results reveal that hardness, strengths, and wet grip efficiency were impaired whereas rolling resistancePublication 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/haItem Metadata only Seasonal Changes in Upper Thermal Tolerances of Freshwater Thai Fishes(2023-01-01) Tongnunui S.; Sooksawat T.; Chotwiwatthanakun C.; Supiwong W.; Wattanakornsiri A.; Beamish F.W.H.; Mahidol University, Rasbora caudimaculata and Mystacoleucus chilopterus, in the Kwae Noi river system in western Thailand.
