Ceramic Bismuth Sodium Samarium Titanate - Barium Titanate at the concentration of samarium 0.04 mol% was preparing by ball mill technique. This research has increased the temperature in the combustion process at different temperatures from 940960 and 970 degrees Celsius for 7 hours. The results showed that firing at different temperatures made the ceramic beads very dense. In addition the study of the crystal structure by XRD technique to study the structure of the ceramic BSNT-BT found that the structure is the same substances in the ceramic group BaTiO3. The results of the study of dielectric properties and ferroelectric properties It was found that the dielectric and P-E hysteresis loops were related and tend to correlate with increasing density with sintering temperature. The mechanical properties of ceramics were tested by measuring the hardness of ceramics at different temperatures with temperatures affecting the changes in various properties of ceramics BSNT-BT.

The special project on Transformative Tray with Pedestal from Tinted Glass Design by Lego Technique has the objectives to study the design and procedure of the transformative tray with pedestal from tinted glass design by lego technique and to investigate the satisfaction of the target group towards the transformative tray with pedestal from tinted glass design by lego technique. The researchers conducted the study and collected the data related to a sketch design of the transformative tray with pedestal from tinted glass design by lego technique which can be modified into 3 ways a rice funnel tray a holy-water bowl tray and monks alms bowl tray. 5 experts will consider the structure of three trays and choose the lotus petal pattern a tray and the color of the lotus petals that the experts like and it must be most suitable. They also give a suggestion to design the transformative tray with pedestal from tinted glass design by lego technique. After that the suggestions were used to survey the satisfaction of the target groups 25 students from Home Economics Business Administration Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon and 25 public people in 5 aspects a product materials utility price and distribution area. Then bring the data into the analysis by using frequency percentage and mean. The result of the analysis shows as follows. From the design and procedure of the transformative tray with pedestal from tinted glass design by lego technique it was found that most experts agree that all three tray are suitable size and proportions for the transformative tray with pedestal from tinted glass design by lego technique. A wooden tray should be used because the lotus petals are plump and delicate. Because the wood tray is strong and the tray should be embedded with glass for a match the colors should be contrasting colors to make the pattern stand out. There should not have additional decoration because the work is outstanding with the pattern of tinted glass. Suggestions for delicate work should be planned and should have a smooth glazing. Satisfaction of the target groups towards the transformative tray with pedestalfrom tinted glass design by lego technique: Satisfaction of 25 students from Home Economics Business Administration Faculty of Home Economics Technology Rajamangala University of Technology Phra Nakhon shows that the respondents were satisfied in the product with the neatness and the beauty of the products with an average of 4.48 at the highest level. Regarding the materials respondents were satisfied with the suitability of the materials used and the strength and durability of materials having an average of 4.48 at the highest level. Regarding the utility respondents were satisfied to use a product as a sacrifice item and as a learning media having the average of 4.56 at the highest level. Regarding the price the respondents were satisfied with the price of 10750 baht with an average of 4.32 at the highest level. Regarding of distribution the respondents were Satisfied in the Buddhist alms shop having an average of 4.60 at the highest level. Satisfaction of 25 public people shows that the respondents were satisfied in the product with the neatness and the beauty of the products with an average of 4.36 at the highest level. Regarding the materials respondents were satisfied with the suitability of the materials used having an average of 4.40 at the highest level. Regarding the utility respondents were satisfied to use a product as a sacrifice item having the average of 4.40 at the highest level. Regarding the price the respondents were satisfied with the price of 12300 baht with an average of 4.24 at the highest level. Regarding of distribution the respondents were Satisfied in the online shop having an average of 4.08 at the highest level.

This research was aimed to study of the effect of dragging force on paper cone falling by using the high-speed video analysis technique. Four different sizes of paper cones ranged from 3.00-5.70 centimeter were used. The cones having the same mass of 12 g and falling from 2.50 meters height were recorded for 240 frames per second and then were analyzed using the Tracker Video Analysis software. The results showed that (1) all four different sizes of paper cones were not freely fall with the Earths gravity due to indirect proportion with time of theirs speeds. The terminal speed of two large cones having diameter of 5.00 and 5.70 centimeters were 4.42±0.03 and 3.97±0.04 meters per second respectively. Only 0.87% of these experimental values were different from the theoretical ones. (2) The theoretical trajectory of these cones falling using the terminal speed from the experimental agrees with the theoretical ones. (3) The experimental drag force showed a second order function of the paper cone’s speed. The evaluated drag force during terminal area is approximately equal to the cone weight. Thus this technique can help students and teachers to visualize simple physics phenomena and relate them to the physics principles learnt in the classroom

Direct thermal decomposition mercury analysis is an efficient technique for determination of mercury in facial whitening creams. The analysis can be performed without any sample preparation. The samples can be weighed and placed directly into the analyzer. Thus there is no chemical waste produced in sample preparation. The time and energy used in sample digestion are saved as well. The calibration curve between mercury absorbance in terms of peak height and weight of standard mercury in the range of 0.1-10 ng was created. The calibration curve was linear followed the equation y=2.003x10-2X– 5.14x10-4 with coefficient of determination (R2) 0.9991. The precision in term of repeatability were 14% and 5.9% rsd (n=3) at 1.2 and 868 µg kg-1 respectively. The recoveries were between 88-110%. The detection limit (LOD) was 0.1 µg kg-1 (3sd/m n=10). The amount of mercury detected in 12 whitening cream samples sold in Chonburi province during the year 2019 were within the safety standard permitted in general cosmetics under the notification of the Ministry of Public except two samples were over the permitted standard.
