Physical properties and consumer acceptance on cotton ball cakes added color powder from carissa carandas l. mixed with maltodextrin
The objective of this research was to study the effects of the processing method on colorant powder from Carissa carandas L. mixed with maltodextrin 3 levels (10 13 and 16 %). The physical properties and consumer acceptance on cotton ball cakes added colorant powder from Carissa carandas L. mixed with all maltodextrin were added at 15% on flour weight. Results from physical properties of cotton ball cakes added colorant powder from Carissa carandas L. mixed with maltodextrin at 10 % was found that the lowest lightness. But also the cotton ball cakes added colorant powder from Carissa carandas L. mixed with maltodextrin at 16 % was exhibited the highest redness and yellowness (p< 0.05) and water activity range from 0.92 to 0.93 (p> 0.05). However the cotton ball cakes added colorant powder from Carissa carandas L. mixed with maltodextrin at 13 % was showed that the highest hardness and chewiness (p< 0.05). Furthermore the colorant powder from Carissa carandas L. mixed with maltodextrin at 10 % was found the lowest adhesiveness (p< 0.05). In addition sensorial evaluation was accepted overall liking score in range 7.63-7.80 (like moderately to like very much. The produce colorant powder from Carissa carandas L. was added maltodextrin from 10 to 16 % (w/w) on (p>0.05).
The effect of electrolysis to recovering tungsten carbide
Recovering of tungsten carbide (WC) with the electrolysis solution in the electrolyte to a reaction with cemented carbide scraps 0.2-1.0 V between temperature from 30-80 C concentration 1-7 N hydrochloric acid solution within 48 hours the results showed the cemented carbide dissolution proper to the influence of voltage temperature and solution concentration. Can recovering tungsten carbide purity over 95.62% of which contain other ingredients include titanium 1.74% tantalum 1.68% and niobium 0.42% concluded that the electrolysis recovering tungsten carbide is appropriate under voltage is 0.4 V temperature 80C 7 N solution of hydrochloric acid recovery rate of tungsten carbide powder about 91.37% with an average particle size of 1.0 m
Use epoxidized natural rubber as coupling agent for reinforcement calcium carbonate filled natural rubber
The reduction of calcium carbonate (CaCO3) particle was prepared by wet grinding method with 40% dispersion. The particle sizes of CaCO3 were studied with various time of wet grinding. It was found that the particle sizes of CaCO3 rapidly decreased in 3 day of grinding after that it was slightly reduce. Therefore the CaCO3 at various time of wet grinding were mixed with concentrate latex (60% dry rubber content DRC). The result showed that the wet grinding for 2 days provided the superior machanical properties. In addition the compound with epoxidized natural rubber (ENR) as a coupling agent was investigated. It was found that the 5 phr of 30% mole percent of ENR results in significantly improved mechanical properties of the rubber vulcanizates.
Car theft warning system via the mobile phone service by SMS
In this research the concept of a burglar alarm system is currently used mainly blaring alarm when an intruder but with todays busy society the voice of alarm no interest or some car owners might not hear the sound of the signal due to the car park. The thieves take the opportunity to have success car theft with mobile messaging technology that costs less and is very active in the daily life of common people. Therefore the development of vehicle theft alarm system with short messages via mobile phone to improve the performance of the car alarm system can send a short message to the mobile phone owner immediately. The motion sensor device that is installed in the vehicle to detect theft or intrusion cars. Invasive test methods such as smashed glass opening the car door. Reaching into the car or inside the front of the car. The system can detect all. It sends messages to the phones owner and the owner of the car did not turn off the car or by calling into the system and then hang up. The system sends a message to every one minute
Tax barriers and guidelines for promoting energy efficient passenger cars
The objective of this paper was study guidelines for taxation to promote the use of energy efficient passenger cars. The passenger car taxation of 4 developed countries; namely Japan Germany United Kingdom (UK) and United States (US) were analyzed and compared with Thai taxation. And studied barriers for promote the use of energy efficient passenger cars in Thailand. This survey conducted by using the close-ended questionnaires collecting data from 400 people who used passenger cars in Bangkok. The results found that tax on acquisition in the developed countries were only subjected to sales tax while Thailand’s acquisition tax composed of customs duty excise duty municipal tax and value added tax. The ownership tax rates of passenger cars in Japan Germany and UK were based on different fuel consumption parameters such as cylinder capacity vehicle weight and CO2 emissions which can promote energy efficient cars. On the contrary the ownership tax rate of USA and Thailand reduces with the age of vehicle. Fuel tax was imposed to support the country energy policy. Opinion survey results of barriers for promoting energy efficient passenger cars in Thailand showed that the significant problems were the lack of incentives measures to promote the use of energy efficient cars.
