Cooling water recovery from water distillation equipment was a research that has the objective to restore the cooling water from distillation equipment which installed at textile chemistry technology department laboratory at Textile industrial and fashion design in Rajamangala University of Phra Nakorn. The research plan was designing and developing the water distillation equipment type cyclon ultrapure water stills model WSC008 of Fistreem company. The outcomes found the designed system could save the tap water consumption 3462.72 square meters per year. That was implied 7617.64 Bath per year of tap water consumption could be save what the tap water consumption rate was 2.22 Bath per square meters. This system was paid back in 3.33 years and the benefit-cost ratio for single project (B/C ratio) was 1.26 (>1). Finally this project was successfully to save the tap water consumption and great benefit investment.

The aim of this is to study the relationship among the parameters such as demographic characteristic and the utilities and media explosures of the student of RMUTP THEWES CAMPUS by using surveying research for 303 sampleis.

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.

The purpose of this study was to study and compare knowledge and perspective of students in faculty of business administration at Rajamangala University of Technology in Bangkok towards business ethics in 4 aspects: customer competitor government and social. The students were classified by gender academic years major subjects. student achievement and parents occupation. The samples in this research were 1734 students. The study participates were selected by stratified random sampling. The 28 item tests and 60 item questionnaires of likerts rating scales were used as the research instrument. Percentage mean standard deviation t - test for independent sample F - test and LSD analysis were statistical methods to analyze data. The results were as follows: 1. Perspective towards business ethics all aspects were in agreeable levels that the social was the highest while the customer including the competitor and the government was in the second rank. 2. There was significant difference for students knowledge towards business ethics at the 0.05 level among students in different gender different academic years different major subjects different student achievement and different parents occupation. 3. There was significant difference for students perspective towards business ethics in each aspect and all aspects at the 0.05 level among students in different gender. different academic years and different major sUbjects. 4. There was significant difference for students perspective towards business ethics in customer competitor social and all aspects at the 0.05 level among students in different student achievement. 5. There was significant difference for students perspective towards business ethics in customer government social and all aspects at the 0.05 level among students in different parents occupation

Dehydration of ethanol to ethylene was investigated over Mn- and Ni-containing mordenites. The synthesized catalysts were characterized by X-ray powder diffraction (XRD) infrared spectroscopy (FT-IR) BET method and temperature programmed desorption of ammonia. The performances on dehydration of ethanol to ethylene for these catalysts were compared at temperature range 250-450°oC WHSV (weight hourly space velocity) of 1 h-1 time on stream of 30-240 min and catalyst weight of 1.0 g. The results showed that conversion of ethanol of the Mn-MOR and Ni MOR was quite similar but selectivity to ethylene of the Mn-MOR catalyst was much higher. The Ni-MOR showed high selectivity to ethane due to its hydrogenation ability.
