 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Performance Test of Rice Combined Harvesters) ผู้เขียน: วิชา หมั่นทำการ*, Kastsunobu Gonno สื่อสิ่งพิมพ์:pdf AbstractField Performance Test in relation to accuracy of operation and cleaning efficiency of two different rice combined harvesters, a locally-made rice combined harvester and a Japanese head-feeding type combined harvester were tested. The locally-made rice combined harvester was tested at two speed ranging from low speed (0.464-0.482 m/s) and high speed (0.787-0.807 m/s). At low speed test, the total grain loss and cleaning efficiency were 3.75-5.963% and 87.93% respectively, compared with the high speed test, the total grain loss and cleaning efficiency being 4.848-8.009% and 89.43% respectively. The Japanese head-feeding type combined harvester was tested at four speed ranging from low speed (0.320-0.395 m/s), medium speed (0.612-0.693 m/s), high speed (0.81-0.835 m/s) and very high speed (1.00-1.063 m/s). It was shown that the most suitable speed of the machine was the high speed which it gave the lowest total grain loss of 3.995-4.747% and cleaning efficiency of 93.20%. |
 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Noise Trading Behavior Analysis in the Stock Exchange of Thailand) ผู้เขียน: ดร.ธนโชติ บุญวรโชติ, รองศาสตราจารย์ , Sanhakit Panyawattananon สื่อสิ่งพิมพ์:pdf AbstractThis study used the causality test suggested by Sellin (1996) to analyze the trading behavior of all investor types on the Stock Exchange of Thailand (SET). The performance test developed by Kamesaka and Wang (2004) was also used to show the trading performance of investor groups in the Thai stock market. The results showed that all investor groups in the SET seem to be informed traders. However, the results from the performance test of each investor group during 2006-2010 showed that foreign investors have the highest performance levels on the SET, while local investors have the lowest. Thus, the SET regulators should help local investors to improve their analytical methods of stock pricing. |

หัวเรื่อง:การทดสอบสมรรถภาพการสืบพันธุ์และการเจริญเติบโตของพ่อพันธุ์โคเนื้อลูกผสม (1/2 ชาโรเล่ย์ 1/4 บราห์มัน และ 1/4 พื้นเมือง) เพื่อปรับปรุงประสิทธิภาพการผลิตโคเนื้อในประเทศไทย สื่อสิ่งพิมพ์:pdf AbstractBull reproductive performance test of Crossbred beef cattle (1/2 Charolais ? Brahman ? Native) using an Andrological examination parameters was performed at Kamphangsaen Campus Kasetsart University throughout the period of 5 years. By using an Andrological and Breeding hygiene parameters testing method for the Crossbred bull at the age of 6 months up to 36 months, the testing results revealed that very high correlation (R2 =0.89) between scrotal circumference and growth traits in young bulls, an average of daily gain weight at preweaning age was 788.33+ 101.52 gram and the superior quality of 6 tested bull semen by using Andrological examination paprameters such as the average of conception rate and after thawing motility of frozen semen were 59.43 and 40%, respectively. All of these tested bulls could be served as superior genetic resources for further genetic merit propagation through AI method to encourage the beef production efficiency of small farms. |
