Publication Metadata only Sequential injection analysis with electrochemical detection as a tool for economic and rapid evaluation of total antioxidant capacity(2011-06-15) S. Chan-Eam; S. Teerasong; K. Damwan; D. Nacapricha; R. Chaisuksant; Flow Innovation-Research for Science and Technology Laboratories (FIRST Labs.; Mahidol University; King Mongkut's Institute of Technology Ladkrabang; Silpakorn UniversityThis work presents a new flow-based coupled electrochemical technique for evaluation of "total antioxidant capacity (TAC)". A sequential injection (SI) with amperometric detection was applied to the TAC analysis of commercial instant ginger infusion..., and fl ow rate to the detector. Gallic acid was used as the standard antioxidant and the capacity was reported as gallic acid equivalent (GAE) unit. TAC measurements of ginger infusions at the optimum condition were performed using the proposed techniquePublication Metadata only An integrated shipment planning and storage capacity decision under uncertainty: A simulation study(2015-01-01) Nyoman Pujawan; Mansur Maturidi Arief; Benny Tjahjono; Duangpun Kritchanchai; Institut Teknologi Sepuluh Nopember; Cranfield University; Mahidol Universitycapacity, working hours of ports, and the dispatching rules of ships significantly affect both total costs and service level. Interestingly, operating fewer ships enables the company to achieve almost the same service level and gaining substantial cost... savings if constraints in other part of the system are alleviated, i.e., storage capacities and working hours of ports are extended. Practical implications – Cost is a competitive factor for bulk items like cement, and thus the proposed scenarios couldPublication Metadata only Novel tools for the surveillance and control of dengue: findings by the dengueTools research consortium(2018-01-01) Annelies Wilder-Smith; Hasitha Tissera; Sazaly AbuBakar; Pattamaporn Kittayapong; James Logan; Andreas Neumayr; Joacim Rocklöv; Peter Byass; Valérie R.

The role of international travel, changing boundaries of vectors, developing models of vectorial capacity under different climate change scenarios and strategies for vector control in outbreaks was all evaluated. Concluding remarks: DengueTools was able... and findings of this work conducted from 2011 to 2016. Research areas: DengueTools organised its work into three research areas, namely [1] Early warning and surveillance systems; [2] Strategies to prevent dengue in children; and [3] Predictive modelsPublication Metadata only Policy measures on strengthening and developing capabilities for national tobacco control in Thailand(2012-12-01) Mondha Kengkarnpanich; Lakkhana Termsirikulchai; Sarunya Benjakul; Mahidol University; Thailand Ministry of Public Healthand management systems, 3) developing surveillance, monitoring and evaluation systems, 4) formulate measures to support research and knowledge management, 5) capacity building and network expansion for tobacco control in various sectors, 6) capacity building...Objective: To assess the situation and report on a national capacity plan for tobacco control under the National Strategic Plan for Tobacco Control (NSPTC) 2010-2014. Material and Method: Systematic documentary review and analysis were managedPublication Metadata only Simple flow injection for screening of total antioxidant capacity by amperometric detection of DPPH radical on carbon nanotube modified-glassy carbon electrode(2012-08-15) M. Amatatongchai; S. Laosing; O. Chailapakul; D. Nacapricha; Ubon Rajathanee University; Flow Innovation-Research for Science and Technology Laboratories (FIRST Labs.; Chulalongkorn University; Mahidol UniversityAn amperometric flow injection (FI) method suitable for evaluation of 'total antioxidant capacity' (TAC) is presented. In this method, a carrier stream of a solution of 2,2-diphenyl-1-picrylhydrazyl radical (DPPH • ) continuously flows through... an electrochemical cell, furnished with a carbon nanotube modified-glassy carbon electrode (CNT/GC) as the working electrode. At the applied voltage of 0.05 V (vs. Ag/AgCl), DPPH • is reduced resulting in a constant electric current. For measurement of the TAC, aPublication Metadata only Alteration of antioxidative properties of longan flower-honey after high pressure, ultra-sonic and thermal processing(2015-06-01) Pittaya Chaikham; Pattaneeya Prangthip; Rajabhat University; Mahidol University© 2015 Elsevier Ltd. All rights reserved. This work evaluated the effect of high hydrostatic pressure (300-500 MPa/25°C/5-20 min), ultra-sonic (20-60% amplitude/20 kHz/5-20 min) and thermal (50-100°C/1-5 min) processing on phenolic contents... and antioxidant capacities of honey from the longan flower. Total phenolic compounds, total flavonoids and antioxidant capacity (DPPH and FRAP assays) were determined. It was found that high pressure, ultra-sonic and thermal treatments had a significant effectPublication Metadata only Alternative leadership in flexible surge capacity-The perceived impact of tabletop simulation exercises on Thai emergency physicians capability to manage a major incident(2020-08-01) Phatthranit Phattharapornjaroen; Viktor Glantz; Eric Carlström; Lina Dahlén Holmqvist; Amir Khorram-Manesh; University of South-Eastern Norway; Försvarsmakten i Halmstad; Sahlgrenska Universitetssjukhuset; Göteborg University, Sahlgrenska Academy; Faculty of Medicine, Ramathibodi Hospital, Mahidol University© 2020 by the authors. Flexible surge capacity aims to activate and utilize other resources than normally are surged in a community during the primary and secondary surge capacity. The presence of alternative leadership, skilled and knowledgeable... in hospital and prehospital emergency management, is invaluable. Thai emergency physicians work at both levels, emphasizing their important role in emergency management of any source in a disaster-prone country. We aimed to investigate Thai emergencyPublication Metadata only Effectiveness of fitness for work interventions for workers with low back pain: A systematic review(2021-01-01) Tomohiro Ishimaru; Odgerel Chimed-Ochir; Sara Arphorn; Yoshihisa Fujino; Hiroshima University; Mahidol University; University of Occupational and Environmental Health, JapanObjectives: Safety at work is important for workers with low back pain (LBP).
