The potential health benefits attributed to mulberry leaf tea and its bioactive compounds such as antioxidant effects cancer chemoprevention and lower blood sugar levels have led to a huge increase of mulberry leaf tea products in the food market. The objectives of this research were to determine the appropriate amount of mulberry leaf tea powder Buri Rum 60 added in 4 snack products which were cook by 4 different process i.e. bread (baked) puifai (steam) peakpoon (stir) and snow lotus (no heat treatment). The Mulberry leaf tea powder was used in the ingredients for 3 levels i.e. 5 10 and 15%. Then the most preferred formula was analyzed for the nutritional values. The result showed that all 4 snacks added with Mulberry leaf tea powder at level of 10% were accepted the most. The nutritive value of these 4 snacks indicated that the moisture contents decreased while protein fiber ash energy increased significantly (p≤0.05). In comparison to the original formulas fat decreased significantly in bread and snow lotus added with mulberry leaf tea powder (p≤0.05) and decreased non-significantly in puifai and peakpoon added with Mulberry leaf tea powder (p>0.05). Carbohydrate increased significantly in bread and peakpoon added with mulberry leaf tea powder (p≤0.05) and increased non-significantly in puifai and snow lotus added with Mulberry leaf tea powder (p>0.05).

This research aimed to develop paper from oil palm empty fruit bunch (Fb) oil palm mesocarp (M) and paper mulberry (P) with chitosan coating to be used as single-use paper bag for dry food products. The optimal pulp preparation conditions for Fb M and P fibers were boiling in 25 25 and 15% NaOH solution at 170 170 and 100°C for 3 hours respectively. The optimal H2O2 concentrations for bleaching of Fb M and P pulps were 40% 40% and 0.2% respectively. The obtained pulps were used to prepare papers with the basis weight of 109 g/m2 . The papers consisted of Fb M and P pulps at ratios of 70:0:30 (FbP) 0:70:30 (MP) and 35:35:30 (FbMP). It was found that FbP paper showed superior physical and/or mechanical characteristics than those of MP and FbMP. FbP papers were then coated with chitosan solutions (0.2-0.6%) to further improve their mechanical properties and reduce their water absorption characteristics. The optimal concentration of chitosan was 0.4%. This study showed that all three types of pulps could be used to produce papers that had equal or superior mechanical- and water adsorption properties as compared to those of commercially available paper bags made from wood pulp.

This research was aimed to study melting behavior of paraffin wax and to evaluate the natural heat convection coefficient of solid cylinder paraffin wax. Two grades of solid paraffin wax; white commercial grade and yellow market grade were studied. Three sizes of flat test tube in diameter 1.5 2.0 and 2.5 centimeters were used. Three different amounts of paraffin indicated from samples’ heights of 5 7 and 10 centimeters were set. The results found the average melting point of both grade paraffin ranged from 44-77 oC. Based on the numerical analysis heat behavior of solid cylinder paraffin at the initial temperature of 50 oC to room temperature of about 30 oC found that natural convection coefficients was ranged from 3 to 9 W/m 2oC. Melting point temperature was found mass independent property while natural convection coefficient declined as the sample’s diameter size inclined

This project aims to develop the guidebook of historic site in Dusit area via augmented reality and to support cultural tourism in providing historic site information. The guidebook is created with nine historic sites in Dusit area which are Benchamabophit Dusitwanaram Temple Devarajkunchon Temple Sukhantharam Temple Mai Thongsen Temple Ratchaphatikaram Temple Ratchaphatikaram Temple Bot Samsen Temple Ruan Mor Phon Museum Parutsakawan Palace and Suansunandha . It is developed by using the SketchUp Pro 2016 the Unity 2017 the Vegas Pro 14.0 and the Photoshop CS6. The results show that tourists can use the guidebook of historic site in Dusit area for basic information. Inside the guidebook there are history of historic sites and bus. Moreover the QR-code can be scanned with augmented technology for information of historic site as English video providing history of historic site and 3D model of historic site with 9Dusit application.

This research studied the efficiencies of ceramic membrane filtration from industrial asphalt for dyeing wastewater treatment by forming a ceramic membrane in a diameter of 6 cm height of 2 cm. An appropriate proportion of industrial ashes: kaolin: sodium hydroxide solution mixed with sodium silicate solution was 46:18:36 at 800 ° C. For the properties analysis of ceramic membrane made from industrial ashes found that a shrinkage value compression resistance and density water absorption value and permeate flux were found 3 percents 0.6 Kilonewtons per cubic centimeter and 1.93 grams per cubic centimeter 45 percents 8.61 milliliters per square centimeter per minute respectively. Structural surface by a scanning electron microscopy was found that the porous inside of material was closely aligned together. Moreover precipitation of synthetic wastewater by using industrial ashes could help to increase the efficiencies of dyeing wastewater treatment. From the experiment it was found that the precipitation of synthetic wastewater with industrial ash was 94 percent filtration efficiency. On the other hand the efficiencies of synthetic wastewater treatment without precipitating of industrial ashes found only 69 percent. Moreover this research offers a new option for industrial wastes utilization.
