This research aims to produce scrap page kaolin of brick construction. The kaolin clay ratio of 100: 0 80:20 60:40 50:50 40:60 20:80 and 0: 100 by volume Add mixed with rice husk and rice 15 percent by weight A total of seven ratios. According to standard tests or TIS. 77-2545 ordinary story brick building. The moisture content and water absorption is increasing. While density Thermal conductivity resistance flexural and compressive strength tends to decrease. The best ratio of 80:20 by volume with compressive strength 43.16 kg / cm 2 and 24.93 percent water absorption. Criteria standard of TIS. 77-2545 requiring compressive strength not less than 35 kg / cm2 and water absorption must not be higher than 25 percent. Can be used in the manufacture of brick construction including building decorative wall can be developed into products. Because skin color and beautiful
Factors Affecting the Concept of Universal Packaging Design
The Purpose of this research is to design and to create the Font of Rajamangala University of Technology Phra Nakhon. The samples of this research are the internal personnel or internal staffs by using Cluster sampling (N1=50) and the external personnel or stakeholders by using Accidental sampling (N2=50) included 100 samples. The research tools are exploratory questionnaire satisfaction questionnaire and efficiency performance evaluation. Data analysis is done by using frequency percentage and standard deviation. Process of research methodology consists of (1) Primary survey about identity attitude (2) conclude and Analysis (3) Design and develop and create font (4) Satisfactory test (5) Efficiency performance of font
The study and development of actions designed to reduce the rate Of production of odor house of wood charcoal community groups were Sarapee aranyaprathet province sakaew
This research study and development of actions designed to reduce the rate of Production of odor House of wood charcoal Community groups Were Sarapee Aranyaprathet Province sakaewPrachantakham Prachinburi. Study materials are made of wood charcoal. And determine the appropriate form furnished house has many of the current medium. Products include standard tests to determine the standard of wood charcoal. in the structure of furniture design. The research study and development of actions designed to reduce the rate of Production of odor House of wood charcoal. vetiver from interviews with experts in the design. Conclusions regarding the manufacture and design of a study to determine specialists as appropriate. Researchers have taken a home furnishing is correct. Then residents of the residential-sized survey about home furnishing 30 who works as follows. Front of the house. The average was 4.6 most of the comforts average was 4.6 most security average is 4.75 most of the design value is 4.7 the overall satisfaction is at its greatest. The test standard furniture. The testing of materials furniture wood charcoal. Static force acting on the basis of a test ride. The static force exerted on the backrest. In the test criteria. The static pressure test on the arm to the side and the force acting on the wing surface at the head. In the test criteria. The static pressure test on the press arm. In the test criteria. Criteria to test the force exerted on the seat and the backrest against the switch. In the test criteria. Force acting on the basis of the test. In passing the test. The impact tests and shock at the surface of the bracket. In the test criteria. Criteria for testing for the one side then drop free In the test criteria.

A fully-balanced current-tunable phase-lead all-pass filter
A new integrable fully-balanced current-tunable in phase-lead all-pass filter is presented. The architecture of the circuit is relatively simple and symmetry with differential signals consisting of merely 6 NPN Bipolar transistors. Without external resistors and matching condition the proposed circuit is very appropriate to further develop into an integrated circuit. Simulation results shown that: frequency is a function of bias current- the increasing currents effect the higher frequency frequency is a function of capacitance low-power-consumption and the maximum useful frequency of 250 MHz
