ระบบปรับอากาศแบบใช้หัวฉีดไอน้ำลดความดัน
ในปัจจุบันทางด้านอุตสาหกรรมมีการนำเอาหม้อไอน้ำมาใช้กันอย่างแพร่หลาย โดยไดน้ำที่ผลิตขึ้นมา ไอน้ำส่วนที่เหลือสามารถนำมาใช้ประโยชน์ได้ โดยนำมาใช้ร่วมกับระบบหัวฉีดไดน้ำลดความดัน เพื่อผลิตสารทำความเย็นขั้นที่สอง Chilled water ที่ใช้ในระบบปรับอากาศแบบใช้หัวฉีดไอน้ำลดความดัน USER STEAM JET INJECTION FOR AIR CONDITION SYSTEM โดยอาศัยหลักที่ว่าเมื่อลดความดันที่ผิวหน้าของน้ำที่อยู่ในภาชนะที่ปิดมิดชิดแล้วทำให้น้ำที่เหลือในอีวาปอเรเตอร์มีอุณหภูมิต่ำลงด้วย น้ำเย็นที่มีอุณหภูมิประมาณ 4.44-21.1 C จะถูกนำไปหมุนเวียนผ่านแอร์เฮนด์ดิ่งยูนิต Air Handing Unit ในระบบปรับอากาศ โดยจะทำการแลกเปลี่ยนความร้อนกับอากาศจึงทำให้บริเวณที่ต้องการปรับอากาศมีอุณหภูมิลดลง
อิทธิพลของสารทดแทนไขมันที่มีผลต่อการเหลือรอดของเชื่อโพรไบโอติคในไอศกรีมดยเกิร์ต
Probiotic is a micro organism that is useful for human bodies and can help creating balances for human intestinal system. The objective of this research is to compare amounts of fat substitutes supplied in the industries in order to determine their ability to encapsulate Probiotic microbes in the production of yoghurt ice cream to ensure maximum survived Probiotic microbes. In this research two fat substitutes Purity SM 100 and CRYSTAL texTM 648 were used to substitute skim milk in the standard formulas in order to study numbers of survived Probiotic microbes and to test the sensory acceptance. For the sensory acceptance it was found that the Probiotic yoghurt ice cream containing 20% Purity SM100 is acceptable at the maximum significance (p ≤ 0.05) because its flavor and taste was better than other samples as well as the best overrun with statistical significant differences (p ≤ 0.05). However by addition of both fat substitutes at different concentrations pH values of Probiotic yoghurt ice cream products did not have statistical significant differences (p ≥ 0.05). When Lactobacilluss acidophilus Bifidobacterium and Streptococcus thermophilus microbial starters were added into the Probiotic yoghurt ice cream using both fat substitutes in place of skim milk at ratios of 10% 15% and 20% respectively under a storage condition of -20oC for 4 weeks it was found that types and amounts of fat substitutes affected the surviving rate of Probiotic microbes in the product with a statistical significance (p ≤ 0.05). The addition of fat substitutes Purity SM100 and CRYSTAL texTM 648 at all concentration levels made Probiotic microbes survive in the product which illustrated that both fat substitutes used in above experiments could encapsulate Probiotic microbe cells. The survived Probiotic microbes were in the range of 108 – 109 CFU/ml in comparison to the Probiotic yoghurt ice cream with the standard formula without the addition of fat substitutes that has survived Probiotic microbes of only 106 CFU/ml.

Degumming process is a fundamental process for silk yam and silk fabric finishing. The main objective is scouring the substrate such as silk gum (sericin) wax and fatty acid from silk fiber. The principle of degumming process is destroying the peptide linkage of amino acid in sericin structure into a small molecule which is soluble in water. The hydrolysis reaction performed by acid alkaline enzyme surfactant as soap and high pressure steam process. The conventional methods favor degumming with soap and sodium carbonate. This process has a problem on the surface area of silk. Proteolytic enzymes can answer this problem but it seldom use because of a specific condition and high cost. For this reason the insteading of papain enzyme from dry latex of Carica payapa Linn. was decided to use for silk degumming at any condition study. This research was concerned with the silk degumming using papain enzyme form dry latex of Carica payapa Linn. The degumming process was performed at the temperature vary from 55 -85 degree Celsius time fromlO to 40 minutes and the amount of dry latex ranging from 0 to 4% owf in order to study the suitable condition for degumming and surface morphology. The efficiency of degumming process was evaluated by determination of tensile strength and stainiqgJest with dire~~ dyes (C.1. Direct Red 80~StaIDing result.will be opposed to degumming efficiency. The result was revealed; the appropriate conditions for silk degumming with dry Carica payapa Linn. s latex were recommended as follows : the amount of dry latex solution of 4 % owf at 75 degree Celsius for 30 minutes. The degummed fibers leaves lustrous soft and surface smooth. This condition does not have effect to tensile strength and fiber surface.
หลักฆราวาสธรรม 4 ในพระบรมราโชวาทพระบาทสมเด็จพระบรมชนกาธิเบศรมหาภูมิพลอดุลยเดชมหาราช บรมนาถบพิตร
This research article aimed to investigate the Gharavasa-dhamma IV which appeared in the royal guidance of His Majesty King Bhumibol Adulyadej the Great. The sample was The Royal Guidance of His Majesty King Bhumibol Adulyadej the Great about religion and morality book of the Department of Religious Affairs (Ministry of Culture 2009). Gharavasa-dhamma IV principle in Buddhism which was defined in Dictionary of Buddhism by Phra Bhramagunabhorn (P.A. Payutto) (2015) was the conceptual analysis framework. The study is based on the documentary research and presented through analytical description. The study found that the royal guidance of His Majesty King Bhumibol Adulyadej the Great can be classified into 3 groups: civil servant youth and Buddhist association with the young Buddhists association. according to the royal guidance literally conformed Gharavasa-dhamma IV was found a total of 21 words of Sacca [truth and honest] 22 words of Dama [taming and training oneself] 15 words of Khanti [tolerance ; forbearance] and 21 words of Caga [generosity]. However in some Royal Guidance there were more than one characteristic as well of Gharavasa-dhamma IV. The royal Guidance therefore has aimed on people to know how to be a good citizen in society for the benefit of People in nation and for their happiness.

In this study the wind speed characteristic and evaluation of wind power generation at Samoeng district Chiang Mai were investigated using wind speed data and wind direction data during time of January 2011 to December 2011 and measured at a height of 20 40 and 80 m above ground level. It was found that the mean wind speed of 3.8 3.92 and 4.30 m/s. While the mean wind direction of 20.73% and indicating from the southwest. The mean of power density of 107 W/m2 the shape parameter (k) was 1.715 1.633 and 1.783 scale parameter (c) of 3.649 3.651 and 4.092 m/s the mean of wind shear coefficient was 0.19. The evaluation of wind energy for electricity generation by install the wind turbine of Nordex N50 from Germany and Vestas V90 from Denmark were capacity of 800 kW and 3 MW. It could produce annual electricity of 1761379 kWh and 3772400 kWh and the capacity factor show 25.13% and 14.35% respectively. Finally the results showed the northern area of Thailand was suitable for wind power development in further.
