Chiang Mai, Thailand

Chiang Mai Rajabhat University is a university in the north of Thailand. It is under the Royal Thai Ministry of Education. The university was founded in 1924 as an agricultural teacher training college. In 1948, it became Chiang Mai Teachers College and offered majors in a variety of subjects. On February 14, 1982, the year of King Rama IX's sixtieth birthday, His Majesty proclaimed Thailand's 36 teacher's colleges to be Rajabhat Institutes; they then began offering majors and degree programmes in non-teaching fields. On March 6, 1985, His Majesty the King graciously granted the use of his royal crest as the Rajabhat Institute emblem. Rajabhat Institute Chiang Mai became Chiang Mai Rajabhat University in 2004.Enrolment is about 30,000, and classes are divided into regular, evening and weekends. Most students come from secondary schools in northern Thailand, some even from remote areas. Chiang Mai Rajabhat University is thus a community institute which provides a comprehensive education for local students and working people.There are five faculties, one graduate school, one international college and one autonomous institute, employing about 500 faculty members.There are four campuses:Wieng Boa, the main campus, is on Chang Puek Road, in the center of Chiang Mai.Mae Sa, the campus of Faculty of Management Science, is in Mae Rim District, 10 kilometers from Chiang Mai.Sa Luang , campus of the Agricultural Center, is in Mae Rim District, 27 kilometers from Chiang Mai.Mae Hong Son campus, in Mae Hong Son, is the center for external services in education.

Dielectric properties of (1 - x)K 0.5Bi 0.5TiO 3 - xBiScO 3 ceramics have been studied for compositions x < 0.5. Single-phase solid solutions occurred for compositions x < 0.25. A frequency-dependent dielectric relaxation was observed, consistent with relaxor behaviour. This gave rise to a relatively stable dielectric permittivity at high temperatures, for example, r 2880 ± 3, between temperatures of 500 and 700 K (1 kHz) for composition x = 0.15. This consistency in relative permittivity occurs at higher temperatures than for other lead-free dielectrics. Parameters from Vogel-Fulcher analysis are compared to other relaxors. © 2012 American Institute of Physics. Source

A study of processing green-chili pastes (Nam Prig Noom) by pressurization (100-600 MPa/30-50°C/20 min), pasteurization (90°C/3-5 min) or sterilization (121°C/4 min), subsequently, their physical, biochemical and microbiological qualities as well as the sensory acceptance were assessed. It was found that pressure at low levels (100-300 MPa) could improve activities of enzyme peroxidase (POD), polyphenoloxidase (PPO) and lypoxygenase (LOX) in the chili paste by more than 100%, while pressures above 500 or 300 MPa combined with heat would significantly inactivate these enzyme activities. Both color parameters and enzyme activities illustrated that though some enzymatic browning occurred with the pressurized products indicated by b* (yellowish) parameter, the magnitude of these browning was still milder than those thermally treated products indicated by-a* (greenness) and L (lightness) parameters, presumably as a consequence of the Maillard reaction. Moreover, the sensory scores were found in accordance with color parameters, firmness and capsaicin contents. © 2013 Copyright Taylor and Francis Group, LLC. Source

Fossil fuel resources are decreasing daily. As a renewable energy, biodiesel has been receiving increasing attention because of the relevance it gains from the rising petroleum price and its environmental advantages. This review highlights some of the perspectives for the biodiesel industry to thrive as an alternative fuel, while discussing opportunities and challenges of biodiesel. This review is divided in three parts. First overview is given on developments of biodiesel in past and present, especially for the different feedstocks and the conversion technologies of biodiesel industry. More specifically, an overview is given on possible environmental and social impacts associated with biodiesel production, such as food security, land change and water source. Further emphasis is given on the need for government's incentives and public awareness for the use and benefits of biodiesel, while promoting policies that will not only endorse the industry, but also promote effective land management. © 2010 Elsevier Ltd.

In this research, 0.94Bi0.5Na0.5TiO 3-0.06BiAlO3 ceramics were prepared by the conventional solid-state reaction and the two steps sintering. X-ray diffraction analysis revealed that both samples showed a pure perovskite phase. Scanning electron microscopy study revealed that both ceramics had similar microstructure. The two steps sintering affects the phase transition temperature of the ceramics. Dielectric and ferroelectric properties of the two steps sintering samples are better than that of the conventional sample. The results were related to the densification and the degree of crystallinity of the samples. © 2014 Copyright Taylor and Francis Group, LLC. Source

A method is proposed to quantify uncertainty on statistical forecasts using the formalism of belief functions. The approach is based on two steps. In the estimation step, a belief function on the parameter space is constructed from the normalized likelihood given the observed data. In the prediction step, the variable Y to be forecasted is written as a function of the parameter θ and an auxiliary random variable Z with known distribution not depending on the parameter, a model initially proposed by Dempster for statistical inference. Propagating beliefs about θ and Z through this model yields a predictive belief function on Y. The method is demonstrated on the problem of forecasting innovation diffusion using the Bass model, yielding a belief function on the number of adopters of an innovation in some future time period, based on past adoption data. © 2014 Elsevier B.V.
