This paper aims to present a basic experimental microcontroller board for use in teaching the microcontroller and programming. Researchers have designed a microcontroller experiment board is cheap easy to carry easy to use. To enable the students to learn programming quickly without having to worry about the hardware. Banana Board supports the basic knowledge necessary to practice the programming of up to 22 topics. It can learn programming from basic to applied work. The connection can be done through a personal computer or connect the board to communicate

The purposes of this research were: 1) to develop Web-Based Instruction (WBI) on “Kingdom of Ayutthaya and Kingdom of Thonburi”กusing student team achievement division technique; 2) to evaluate if the WBI meets an 80/80 efficiency criterion; 3) to compare the students’ learning achievements by pre-test and post-test; and 4) to examine student satisfaction towards the WBI. The sampling group selected by purposive sampling was 25 primary education (grade 5) students in the second semester of academic year 2012 at Wattrithosathep school in Phra Nakhon district Bangkok. The research instruments consisted of two unit of WBI; a learning achievement test administered before and after the learning; and the evaluation form of the student performance. The statistical tests employed to verify the efficiency of the WBI were the E1/E2 efficiency index and t-test. The research result revealed that the efficiency of the developed web-based instruction (WBI) was 84.00/82.80 which was higher than standard criterion 80/80 and comparative of student’s achievement it was found that the student achieved learning progress significantly level of .05. Finally it was found that the learners opinion after using the developed web-based instruction (WBI) was very satisfactory.

Biomass yield between 56 accessions of leucaena were observed at Suwanvajokkasikit Field Crops Research Station Nakhonratchasima province. Randomized block design was used with 3 replications and 56 accessions as treatments. Leucaena was harvested at 2 years of age. Plant length wood yield branch yield and leaf yield were collected. Averaged plant length was in range of 6.84-11.87 meters with KU19 was highest in length. Five accessions that produced more wood yield were KU15 KU38 KU1 KU19 and KU10. Yield of these accessions were 24.07 21.96 16.71 15.36 and 14.95 t/rai with ash content at 1.43 1.04 1.76 3.66 and 1.34 percent respectively while native leucaena (KU20) had the lowest yield (0.91 t/rai). Branch yield among the accessions; KU1 KU10 KU38 KU 15 and KU19 had the greatest branch yield averaged 3.04 2.76 1.62 1.42 and 1.38 t/rai respectively. While top five in leaf yields were in KU15 KU56 KU45 KU39 and KU19 at 1.12 1.11 0.88 0.87 and 0.86 t/rai respectively.

This research aims to study the process of puffed Job’s Tears in order to decrease its frying process so that Job’s Tears could be aerated by cooking in a microwave oven. The optimum processing conditions for producing puffed Job’s Tears include soaking them for 22 hours at ambient temperature followed by steaming them at pressure 15 lb/in2 for 20 minutes. Finally the Job’s Tears was dried in the tray dryer at 60 oc for 3 hours 15 minutes to decrease the moisture content to 11-13 %. The Job’s Tears containing 10 grams in weight was by far the best quality when cooked in a microwave oven at 800 watts for 1 minute 30 seconds. The puffed Job’s Tears snack contained 3.27 % moisture 13.32 % protein 14.63 % fat 67.93 % carbohydrate 0.85 % ash and 1.95 % fiber.

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
