Phitsanulok, Thailand

Naresuan University is a government sponsored university in Phitsanulok, northern Thailand. It was established as a separate university on July 29, 1990, which was the 400th anniversary of the start of the reign of Phitsanulok-born King Naresuan the Great. A courtyard with a statue of King Naresuan is located on the grounds and the students regularly pay their respects before it. The university has about 20,000 full-time students. Wikipedia.

Oral lichen planus and oral lichenoid drug reactions have similar clinical and histologic findings. The onset of oral lichenoid drug reactions appears to correspond to the administration of medications, especially antihypertensive drugs, oral hypoglycemic drugs, antimalarial drugs, gold salts, penicillamine and others. The author reports the case of 58-year-old male patient with oral lichenoid drug reaction, hypertension and diabetes mellitus. The oral manifestation showed radiated white lines with erythematous and erosive areas. The patient experienced pain and a burning sensation when eating spicy food. A tissue biopsy was carried out and revealed the characteristics of lichen planus. The patient was treated with 0.1% fluocinolone acetonide in an orabase as well as the replacement of the oral hypoglycemic and antihypertensive agents. The lesions improved and the burning sensation disappeared in two weeks after treatment. No recurrence was observed in the follow-up after three months. © 2010-Journal of Drugs in Dermatology.

To determine the prevalence of low back pain (LBP) among rice farmers in a rural community in Phitsanulok, Thailand. A cross-sectional survey was conducted among 283 rice farmers in Wangnamkhu subdistrict, Muang district, Phitsanulok province, a rural community in Lower Northern Thailand. Face-to-face interviews with a structured closed-end questionnaire were performed to collect information on the presence of LBP in lifetime, within the last 12 months prior to and at the time of the present study. The lifetime, 1-year (12-month) and point prevalence rates of LBP were 77%, 56% and 49%, respectively. No relationship between age and LBP was found. However women (61%) had significantly greater 1-year prevalence than men (51%). Ninety-five percent of LBP rice farmers were chronic (experiencing pain longer than 12 weeks) with a mean duration of 292 weeks (5.6 years). The prevalence of LBP among Thai rice farmers is high. Further research should investigate risk factors among this group of the population to design appropriate preventive measures.

We argue that all homogeneous and isotropic solutions in nonlinear massive gravity are unstable. For this purpose, we study the propagating modes on a Bianchi type-I manifold. We analyze their kinetic terms and dispersion relations as the background manifold approaches the homogeneous and isotropic limit. We show that in this limit, at least one ghost always exists and that its frequency tends to vanish for large scales, meaning that it cannot be integrated out from the low energy effective theory. This ghost mode is interpreted as a leading nonlinear perturbation around a homogeneous and isotropic background. © 2012 American Physical Society.

We present the first example of a unitary theory of Lorentz-invariant massive gravity, with all degrees of freedom propagating on a strictly homogeneous and isotropic, self-accelerating de Sitter background. The theory is a simple extension of the quasidilaton theory, respecting the symmetry of the original theory but allowing for a new type of coupling between the massive graviton and the quasidilaton scalar. © 2013 The Authors.

Based on the Unruh effect, we calculate the critical acceleration of the Bose-Einstein condensation in a free complex scalar field at finite density in the Rindler space. Our model corresponds to an ideal gas performing constantly accelerating motion in a Minkowski space-time at zero-temperature, where the gas is composed of the complex scalar particles and it can be thought to be in a thermal-bath with the Unruh temperature. In the accelerating frame, the model will be in the Bose-Einstein condensation state at low acceleration; on the other hand, there will be no condensation at high acceleration by the thermal excitation brought into by the Unruh effect. Our critical acceleration is the one at which the Bose-Einstein condensation begins to appear in the accelerating frame when we decrease the acceleration gradually. To carry out the calculation, we assume that the critical acceleration is much larger than the mass of the particle. © 2015 The Author.
