Item Metadata only Mathematical modelling of granular flows and its applications(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Wariam Chuayjan; Benchawan Wiwatanapataphee; Wu, Yong Hong; Tang, I. MingPublication Metadata only Numerical simulation of granular flow during filling and discharging of a silo(2010-12-10) W. Chuayjan; S. Pothiphan; B. Wiwatanapataphee; Y. H. Wu; Mahidol University; Curtin UniversityIn this study, we simulate the static and dynamic processes of granular flow during filling and discharging of a vertical-sided silo with conical hopper bottom. The granular material is an assembly of 7,500 soybeans. Based on the discrete element... method, the governing equations for the granular flow are solved by the centred finite difference scheme. The effects of inlet flow rate and bottom angles on pressure distribution on the hopper wall throughout the static process of material fillingItem Metadata only Biogas upgrading towards acetic acid production using Clostridium thailandense supplemented with granular activated carbon (GAC) and L-arginine: A genomic analysis approach(2024-12-01) Chaikitkaew S.; Wongfaed N.; Mamimin C.; O-Thong S.; Reungsang A.; Chaikitkaew S.; Mahidol UniversityThis study explores the impact of granular activated carbon (GAC) and L-arginine supplementation on biogas upgrading and acetic acid production employing Clostridium thailandense. GAC and L-arginine concentrations ranged from 0 to 20 g/L and 0 to 5Publication Metadata only Hydrogen sulfide removal using granular activated carbon biofiltration inoculated with Alcaligenes faecalis T307 isolated from concentrated latex wastewater(2010-08-01) Cheerawit Rattanapan; Duangporn Kantachote; Rong Yan; Piyarat Boonsawang; Mahidol University; Prince of Songkla University; Nanyang Technological UniversityA novel biofiltration of pure culture was developed for H2S removal from synthetic biogas using Alcaligenes faecalis T307 immobilized on granular activated carbon (GAC) as packing materials. The effect of operating parameters, including inlet H2SPublication Metadata only The electric field distribution of a hybrid rectangular and circular waveguide resonator for use in granular material dielectric measurements(2015-01-01) Navapadol Kittiamornkul; Kamon Jirasereeamornkul; Supaporn Kiattisin; Kosin Chamnongthai; Kohji Higuchi; King Mongkuts University of Technology Thonburi; Mahidol University; University of Electro-Communications© 2015 The Institute of Electrical Engineers of Japan. This paper represents a design for a hybrid rectangular and circular waveguide resonator. The resonator is designed specifically for the purpose of granular dielectric measurements, whichPublication Metadata only Two-phase flow of air and soybeans during a silo discharge process(2012-12-01) W. Chuayjan; W. Jumpen; P. Boonkrong; B. Wiwatanapataphee; Thaksin University; PERDO; Mahidol UniversityThe paper aims to present mathematical model and numerical simulation of a granular material flow during a silo discharge process. The material flow in the silo is a form of two-phase flow consisting of particulates and an interstitial fluid... and 0.12 m are chosen for this investigation. The results show that the mathematical model can capture the granular material flow in the silo. The bottom design has significant effect on the velocity, pressure and shear rate in the granular materialItem Metadata only Using alginate-based granular activated carbon hybridized with silica derived from sugarcane bagasse residues for adsorption of uremic toxins in dialysate(2025-09-01) Arpasopana N.; Boontanon S.K.; Abdulroman N.; Rasmee T.; Prachakittikul P.; Sutthasupa S.; Worasuwannarak N.; Srifa A.; Koo-amornpattana W.; Klaitong P.; Chaiwat W.; Arpasopana N.; Mahidol UniversityIn a wearable artificial kidney system, regeneration of spent dialysate solution, containing major uremic toxins such as creatinine and uric acid, is necessary for waste mitigation. In this study, hybrid granular activated carbons (GACs) of powderedItem Metadata only Advancing Organ-on-Chip Models With a Sacrificial Granular Hydrogel Strategy for Enhanced Permeability and Biomimicry(2025-01-01) Caires H.R.; Castillo-Fernández Ó.; Sima N.; Magalhães M.V.; Benavent-Claró A.; Masó-Castro N.; Roobsoong W.; Fernandez-Becerra C.; Hernández-Machado A.; del Portillo H.A.; Barrias C.C.; Caires H.R.; Mahidol University, their small mesh size may restrict pathogen migration and cell–pathogen interactions, both critical for establishing infection on-chip. To overcome this limitation, this work develops a “reversed” granular hydrogel strategy that creates interconnectedItem Metadata only Effectiveness of 1- and 2-per cent acetic acid solutions in the 2-week treatment of granular myringitis(2023-01-01) Prakairungthong S.; Werawatganon T.; Chantarawiwat T.; Warnpeurch L.; Atipas S.; Thongyai K.; Suvarnsit K.; Limviriyakul S.; Mahidol UniversityBackground: Granular myringitis is characterised by de-epithelisation of the tympanic membrane. Patients present with intermittent otorrhoea, otalgia or itching. With improper or inadequate treatment, granular myringitis could cause ear canal... fibrosis and stenosis. There are no standard topical ear drops for granular myringitis. Treatments have inconsistent success rates and variable timelines.
