Mpirically Derived Equation From Simple Heat Index For Calculating Wet Bulb Globe Temperature: A Case Study Of Thailand, Wutthichai Paengkaew, Atsamon Limsakul, Rittirong Junggoth, Somsak Pitaksanurat
Applied Environmental Research
The Wet Bulb Globe Temperature (WBGT) index is a standard for assessing environmental heat stress, but the requirement of expensive instrument with specialized maintenance is limited its use. This study aims to develop the empirical equation to estimate the WBGT from Heat Index (HI) calculated from portable temperature and humidity recorder (THR), based on the data collected at seven sites covering all regions of Thailand. Comparative analysis shows that the HI values calculated from THR (HITHR) are consistent well with those measured from the thermal environmental monitor (HIQT36) as evidenced by a highly positive correlation between them (r=0.97; p<0.01; n=4,303). These results suggest high reliability of the portable THR and its acceptance to be used instead of the standard QT36 device. Based on a simple linear regression developed to estimate WBGT from the HITHR, it was found that the model accounts for at least 90% of the variance of the observed WBGT (dependent variable). In addition, validation of the model with the statistical methods shows relatively small errors of the estimated WBGT values in comparisonto the observed values. With this evidence, the developed empirical regression equation can be used to estimate WBGT with high accuracy and confidence. Simple and easier to use for the practitioners who are involved in public health works at community level, a heat monitoring tool kit consisting of a THR, WBGT chart and recommended actions were further developed based on the results obtained. This tool kit is a low-cost and simple device which can be used by various community-level stakeholders to prevent and reduce heat injuries and deaths of risk groups, especially the elderly. This tool is necessary in light of anthropogenic-induced warming and Thailand's aging society.

Assessments Of Nipa Forest Using Landsat Imagery Enhanced With Unmanned Aerial Vehicle Photography, Tantus Piekkoontod, Bhumiphat Pachana, Karnjana Hrimpeng, Kitsanai Charoenjit
Applied Environmental Research
Nipa palms are exposed by the transformation of land use and land cover changes (LULCC) due to changes to aquaculture and orchards. Modern remote sensing for environmental monitoring of LULCC has been made easier by the use of high spatial resolution images, innovative image processing and Geographic Information Systems (GIS). The expense of high-resolution satellite imagery has resulted in investigators moving to open sources (e.g., Landsat), therefore, the interpretation of images at a medium resolution can be classified simply as LULCC classes and are constrained by the detection of small-scale disturbances. This research applied Landsat imagery with very high-resolution imagery …

Optimizing The Extraction Of Phenolic Compounds With High Antioxidant Activity From Mango Seed Kernel Wastes Using Response Surface Methodology, Francis D.C Siacor, Camila F.Y. Lobarbio, Evelyn B. Taboada
Applied Environmental Research
Mango seed kernels (MSK), which are waste streams in the mango processing industry, are good sources of phenolic compounds with high antioxidant, anti-bacterial, and anti-viral properties. These phenolic compounds are reported to have an increasing demand over the years in the quest for healthy ready-to-eat food and nutraceuticals. To recover these compounds from MSK, solid-liquid extraction (SLE) can simply be applied, although there is a knowledge gap in the systematic exploration of this process for mango-based phenolic compounds. In this work, phenolic compounds were extracted from MSK through SLE using ethanol-water solvent system. A statistical-based approach was used to evaluate …
