Item Metadata only Consequences of seed dispersal, seed predation by animals and natural disturbance on the recruitment of spondias axillaris, a light-demanding zoochorous tree(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Wirong Chanthorn; Brockelman, Warren Y.Item Metadata only Physical and rheological properties of mixture of waxy corn starch and hydrocolloid dispersions during and after heating(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Piyada Achayuthakan; Manop SuphantharikaItem Metadata only Reinforcement effect of multi-walled carbon nanotube with and without surface modification in nitrile rubber(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Atip Boonbumrung; Chakrit Sirisinha; Pongdhorn Sae-Oui; Kalyanee Sirisinha; Toemsak Srikhirinthe degree of MWCNT dispersion and MWCNT-NBR interaction were conducted via shear field enhancement and MWCNT modification approaches. The results show that the MWCNT filled system demonstrates the greatest magnitude of reinforcement in mechanical properties... properties. Neither nip width nor milling pass number plays a strong role in MWCNT dispersion. On the contrary, the degree of MWCNT dispersion is found to increase with increased mixing time, shear field, and modification techniques. The greatest degreeItem Metadata only Development of petroleum industry byproduct sulfur to be used in rubber vulcanization(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Pathompong Pangamol; Chakrit Sirisinha; Pongdhorn Sae-Oui; Supa Wirasateof sulfur with TDAE oil as carrier was developed and then determined for its properties after being used in different rubber matrices. Enhancement in sulfur dispersion was focused and compared with uncoated petroleum-based sulfur. The results measured from... Plc. Co., Ltd. possessed potential utilization as the vulcanizing agent in rubber as substitution for the commercial natural-based sulfurs. Finally, the TDAE oil was used to coat the petroleum-based sulfur as dispersing agent. The ratio of sulfurItem Metadata only A study of parameters affecting properties of tire tread compounds(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Puchong Thaptong; Chakrit Sirisinha; Pongdhorn Sae-Oui; Pairote JitthamIn this study, passenger car radial (PCR) tire tread compounds based on styrene butadiene rubber (SBR) were prepared. Two types of SBR, i.e., solution SBR (SSBR) and emulsion SBR (ESBR), and two types of silica, i.e., highly dispersible silica (HDSi... to the higher proportion of mono- and di-sulfidic linkages. Surprisingly, silica type played a little role in WG, FSE, and degree of filler dispersion in this study despite the fact that HDSi is claimed to offer greater dispersibility. Results suggestItem Metadata only Preparation and characterization of hydrogenated soybean oil as a controlled release regulator for metoprolol tartrate pellets(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Krisanin Chansanroj; Nuttanan Sinchaipanid. Controlled release metopr olol pellets were prepared by hot melt fluid bed coating technique. The drug was dispersed in melted HS O and directly sprayed on nonpareils. The poor wettability of HSO enhanced the buoyancyItem Metadata only Preventative measures against online hate speech : a case study of political conflict(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Wanpadej Hongthong; Punchada Sirivunnabood; Veenunkarn Rujiprak; Sanya Niempraditcontrols. It is recommended that there should be amendment approaches to control the dispersals of online hate speech in the case of political conflict for the agencies involved to take action. These are (1) set criteria to identify the social online usersItem Metadata only Influence of aromatic content in rubber processing oils on viscoelastic behaviour and mechanical properties of rubber for tyre tread application(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Yotwadee Chokanandsombat; Chakrit Sirisinha; North, Alastair M.; Pongdhorn Sae-Ouiwith increased aromatic compounds and PCA contents in the RPOs. This implies that there is an enhancement in the degree of filler dispersion in the rubber compounds, which is due to the increasing compatibility between the RPO and the rubber matrix. In contrastItem Metadata only Crustal structure studies beneath Thailand using a receiver function and ambient noise tomography, and the regional moment tensor of the 5 may 2014, MR 6.5, Chiang Rai earthquake and its aftershocks(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Sutthipong Noisagool; Weerachai Siripunvaraporn; Pichet Kittara; Chaiwoot Boonyasiriwatcomposition than other regions. High Poisson's ratio anomalies agree with the geological features. In the second method, Rayleigh and Love wave tomography were constructed from the ambient seismic noise field. Group velocity dispersion curves were measuredItem Metadata only Tack reduction by surfactants and development of acrylate polymer films for pharmaceutical coatings(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Sathaporn Nimkulrat; Krisda Suchiva; Pranee Phinyocheepdispersions (Eudragit®). The results from the peel tests demonstrated that glyceryl monostearate (GMS), Span 60 and Span 40 could reduce the tackiness of both Eudragit NE30D and Eudragit RS30D films. The components and mechanical properties of the films were
