The purposes of the research on soy milk product mixed with carrot were to study the preparation of soy milk carrot juice extraction appropriate ratio of soy milk to carrot juice and sugar content shelf - life and consumers’ acceptance of the product. The study was focused on the product’s physical quality chemical composition sensory quality and micro-organism content. The results of the research revealed that soy milk with soy bean : water at 1:4 (by dry soy bean weight)used in extraction process; blanching of carrot prior to extracting which yields 70.31% of the juice and 4580 μg . (763.33 R.E) beta - carotene per 100 grams of carrot which is a higher amount than extracting fresh carrot ; the ratio of soy milk to carrot juice at 70:30 and 5% of sugar content by weight are appropriate in soy milk mixed with carrot production. The L*value a*value and b* value were 66.79 25.24 and 39.25 respectively. The viscosity was 17.33 centipoint; total soluble solid was 11.67 brix; and pH was 6.25. The acceptance scores on color flavour texture and overall preference were 7.98 8.00 7.93 and 8.05. This means preference on color and texture was moderate; the preference on flavour and texture was very high. For chemical composition it was found that there were 71.08 kcal. energy 4.40 g. protein 1.56 g. fat 9.86 g. carbohydrate and 1378 μg.(229.67 R.E.) beta-carotene per 100 grams. The cost of raw materials was 6.41 baht per 180 ml./bottle. The study of consumers’ product acceptance showed that most consumers had knowledge on nutrition; they accepted and had preference on the product at the moderate level. The price of 12.00 baht per 180 ml. bottle was accepted. It was also found that there was no physical or chemical change of the product when kept at 70C for 14 days. Total bacterial count was 4.8x10 CFU/cm3 when compared to Soy Milk Thai Community Product Standard (SPC. 529/2004) which specified that not exceeding 1x104 CFU/ cm3 should be found in the product. It was evident that the product was still safe for consumption when kept for 14 days.

We present the comparison of CDMA MAC protocol with and without beat noise by using 2-D optical CDMA MAC protocol over WDM networks. We use the asymmetric primehop sequence code. Moreover we analyse the effect of the number of available wavelengths in tenns ofaverage number of attempted to transmissions per time slot (offered load) and beat noise is considered. The presented numerical results based on the throughput and delay time versus the offered load. We divide into two parts. The first one we consider the effect of the number of available wavelengths. Another is the effect of with and without beat noise in the 2-D OCDMA over WDM systems.

The objective of this research project is to develop an effectively applicable prevention of heat for concrete masonry unit wall. By using kaolin mixture coir rice straw and husk as a major ingredient in concrete to replacing usual stone dust the hollow non-load-bearing concrete masonry units obtained had the size of 70 X 190 X 390 mm. The test results showed that the reliably ideal ratio of these mixture materials had to be from the combination of kaolin coir rice straw and husk by replacing them at 5%: 5%: 15% and 50/0. The block obtained also had other certain qualifications such as Weight at 6.08 kg. water absorption at 7.96% and compressive strength at 65.4 ksc. Moreover these combined materials harbored heat capacity less than the standard concrete masonry units with the weight not more than 29%.

The purpose of this study was to compare undergraduate students reading writing performance and interest in learning English through reading instruction with and without computer in PowerPoint Program at Rajamangala University of Technology Phra Nakhon Bangkok Commercial Campus. The subjects for this study consisted of 80 undergraduate students in the first semester of the 2005 academic year of Rajamangala University of Technology Phra Nakhon Bangkok Commercial Campus. They were selected by using simple random sampling and divided into the experimental and control groups with 40 students in each. The randomized control group pretest -posttest design was used in the experiment. The experimental group was taught through the method in the reading instruction with computer in PowerPoint Program whereas the control group was taught through the method in the reading instruction without computer in PowerPoint Program. Each group was taught with lessons of the same content for sixteen 150 minute periods. The instruments used in the study were English reading writing performance tests and interest in learning English. The t-test for independent samples score was statistically used for data analysis. The results of the study indicated that: 1. The English reading performance between the experimental and control groups was significantly different at the .05 level. 2. The English writing performance between the experimental and control groups was not statistically significant. 3. The interest in learning English between the experimental and control groups was significantly different at the .05 level.
