Puffing technique is the process that can improve physical properties of fruit and vegetable. However, the effect of chemical composite in foods on puffing characteristics is still lack of study. Therefore, potato and apple slices were comparative study on physical properties. Potato and apple were sliced into 2.5 mm thickness and 2.5 cm in diameter. Potato slices were treated by hot water...

Neutron monitor (NM) and Bare (lead-free) neutron counters are ground-based detectors to detect the variation of intensity in cosmic rays. In addition, the bare detector to neutron monitor count rate ratio (Bare/NM) provides information on the cosmic ray spectrum. In the present work, we utilized data from the Princess Sirindhorn Neutron Monitor station at Doi Inthanon, Thailand, with the...

An optimum cumulus parameterization scheme was determined for the Weather Research and Forecasting (WRF) model for Northern Thailand. This was then applied to model PM10 data in Chiang Mai city for 10-days during a high haze event using an updated WRF version (v. 3.7) and updated land use categories from the Moderate Resolution Imaging Spectroradiometer (MODIS). A higher resolution...

Two series screw conveyor dryer potentially dries agricultural product especially paddy rice. However, the effect of screw speed, drying temperature and drying cycle on decreased moisture content and energy efficiency is non-previous literatures. In this study, the paddy rice was carried into dryer at 4.8 kg/batch under screw speed 35, 50 and 75 rpm and drying temperature of 50, 70 and 90°C....

In this study, comparison of spectral ultraviolet irradiance at 305, 310, 324 and 380 nm at satellite overpass time retrieved from OMI/AURA satellite with that from ground-based measurement was performed at Nakhon Pathom (13.82 N, 100.04 E), Thailand. The analyzed data period comprises from 1 January 2010 to 31 December 2015. The comparison results clearly show the overestimation of satellite...

Clouds play very important role in the variation of surface solar radiation and rain formation. To understand this role, it is necessary to know the physical and geometrical of properties of cloud. However, clouds vary with location and time, which lead to a difficulty to obtain their properties. In this work, a ceilometer was installed at a station of the Royal Rainmaking and Agricultural...
