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 consistingPublication 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 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/haPublication Metadata only Probabilistic Risk Assessment of Inorganic Arsenic via Consumption of Herbs Collected in Thailand(2018-01-01) Nuntawat Monboonpitak; Suthep Ruangwises; Sawanya Buranaphalin; Nongluck Ruangwises; Chulalongkorn University; Mahidol Universitydetermined using atomic absorption spectrometry coupled with a hydride generation system (HG-AAS). Total arsenic contents in fresh herbs and lyophilized herbs ranged from 3.39 to 119 ng/g wet weight (wet wt) and from 41.0 to 156 ng/g dry weight (dry wt...), respectively. Inorganic arsenic contents in fresh herbs and lyophilized herbs ranged from 2.09 to 26.9 ng/g (wet wt) and from 23.5 to 55.5 ng/g (dry wt), respectively. Percentages of inorganic arsenic to total arsenic in herbs ranged from 22.7 to 62.0%.

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.

Comprehensive model evaluations demonstrated that the modeling system had the capacity to reproduce the observationsPublication Metadata only Dry powder inhaler in mechanical ventilation and influence of ventilator circuit-related factors on aerosol delivery during mechanical ventilation(2019-01-01) Warangkana Pornputtapitak; Nashwa El-Gendy; Mahidol University; Beni-Suef Universityin the form of wet aerosols via nebulizers or pressurized metered-dose inhalers (pMDI). However, an ineffective and inconsistent aerosol delivery due to drug loss in a ventilated system is a major problem for aerosolized therapy in these patients. Dry powder... inhaler (DPI) has been a promising inhaler that has no 'rain-out' of wet aerosol on the circuit. This review will summarize the state of the art for aerosol delivery to mechanically ventilated patients with special emphasis on emerging opportunitiesPublication Open Access Energy Use and Consumption Patterns of Maize Cultivation - A Case Study in Thailand(2021) Sirikarn Thongmai; Thanakrit Neamhom; Withida Patthanaissaranukool; Supawadee Polprasert; Mahidol University.
