This research study is 1) study the current situation and problems in the research of the faculty Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. 2) Analyze the factors that affect the potential success of the research faculty Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. 3) To find ways to build the capacity of teachers to do research Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. The qualitative research that the researchers created a questionnaire depth individually. By choosing the essentials included 15 people the researchers collected qualitative data. Then check the integrity of data by means of a triangle (Triangulation Methods). What is the difference of the essentials. The difference in time of data and the different places that provide information. Including monitoring the research. Save data As defined without prejudice in any way the results appear. The information is accurate and aligned. So bring content analysis (Content Analysis) with reading comprehension and classified into categories. To bring a conclusion. To provide research and research objectives defined. The results showed that The current state budget problems without doing sufficient research. No research consultants with expertise advice. There is no budget for research No knowledge of writing projects. Research Methodology. No consultants to provide advice. Factors affecting success include research. Must have knowledge a budget and a consultant with expertise. To advise the duration of the research. This is Explains the factors that affect success in doing research. Must have sufficient funding for research in science and other research teams. Ability to successfully complete the research. And ways to promote research. To do research to achieve that. Administrators need a policy that is concrete. Budget amply Encourage understanding and reward as well.
ปัจจัยที่ส่งผลกระทบต่อการทำงานวิจัยของมหาวิทยาลัยเทีโนโลยีราชมงคลพระนครต่อมาตรฐานและคุณสมบัติของอาจารย์มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร
This research aimed 1) to study the current situation and problems in research 2) the factors that affect the standards and qualification of university lectures 3) analysis find the ways to promote the research and research standard Rajamangala University of Technology Phra Nakhon. This research is a combination of quantitative and qualitative research. The research tool is a questionnaire and personal interview . This research tool has been validated by experts to improve quality. 285 sets were used to collect quantitative and analyzed processed by computer. The qualitative data are 20 possible combinations of the content analysis and interpreting descriptive. The results showed that there are 1-2 research paper of university lecturer Rajamangala University of Technology Phra Nakhon in the past five years’ experience the percentage is 54.03 the overall policy and research management is moderate level by policymakers need to keep in practice. On the other hands the factors that contribute to the research were average level namely honorary researcher honorable certificate was at a high level. For the guidelines on research to achieve the standards was average level. The qualitative data is found that the administrators must support promote assist the research and facilitates everything required to provide adequate funding for university lecturer who are interested in doing research and to provide research trainers experience expertise and related fields in order to conducting a variety of research and encourage to promote the research in publish both of home and abroad.
การตรวจวัดปริมาณฟอสเฟตในน้ำผิวดินจังหวัดลพบุรี ด้วยระบบวิเคราะห์แบบไหลชนิดโฟลอินเจคชันอย่างง่าย
A simple flow injection analytical system for an automatic determination of phosphate in water samples using the molybdenum blue method was developed. Samples were injected and mixed with ascorbic acid used as a reducing agent. The absorbance of the resulting molybdenum blue complex was measured at 880 nm by a spectrophotometer. The optimal conditions of this system were 2 mL/min of carrier flow rate 1000 μL of sample volume 60 centimeters of mixing tube length and 0.020 mol/L of ascorbic acid. The proposed method showed reliability high sensitivity spend small amount of reagents and samples and fast sample throughput (52 samples/hour). The limit of detection (LOD) was 0.015 mg P/L of phosphate. Precision obtained injecting a phosphate standard solution of 0.50 mg P/L (n=10) was 1.81%. This system can be applied to determination of phosphate content in surface water samples in Lopburi province by comparing with a standard method. It was found that obtained from the developed system agreed well with the standard method using the pair t-test (tstat 0.04 < tcrit 2.36). This flow injection analysis system has no effect from arsenate and silicate interference for the analysis of natural water samples.
ฤทธิ์การต้านอนุมูลอิสระของน้ำนมข้าวโพดสามสายพันธ์
The purpose of this research was to analyze carotenoid content anthocyanin content phenolic compound content and the antioxidant activity by 2 2-diphenyl-1-picrylhydrazyl scavenging capacity (DPPH) and 1 10-Phenantroline (Phen). In the 3 varieties of corn milk which were the Queen Ruby Siam strain (Purple corn milk) (White corn milk) Sweet strain (Yellow corn milk). It was found that the samples of 3 types of corn milk have total carotenoid content were 0.45+0.00 0.29+0.02 and 0.68+0.00mg/l respectively. Anthocyanin content measured by pH-differential method were 2.86+0.01 1.71+0.03 and 0.80+0.01 mg/l respectively. The total amount of phenolic compounds were 12.00+0.02 10.05+0.00 and 8.62+0.09 mg/l respectively. The ability to resist free radicals by DPPH method were equal to 96.50+0.10 47.10+0.01 and 60.91+0.08 respectively. The antioxidant activity using Phen method were 133.98+0.76 111.17+0.48 and 86.61+0.98 mg/l respectively.
การจำลองพฤติกรรมการเผาไหม้ของเตาประหยัดแก๊ส s-10 ด้วยวิธีพลศาสตร์ของไหลเชิงคำนวณ
The objective of this research is to study the combustion behavior of a gas-saving burner S-10 using computational fluid dynamics (CFD). The simulation model was created using Fluent 6.3 in 3D-model of the same size of the burner. LPG pressure of 4 psi was released for this study. The combustion behavior was shown in temperature contour and velocity vector. The CFD results were verified by measuring the temperature around the burner head with a vessel. From the study it was found that the CFD’s results of flow velocity and combustion temperature distributions were validated with the experimental values. The CFD’s result errors were less than 10.35% and 11.87% comparing with the velocity and temperature measurement respectively. The fluid flow and combustion behaviors can be described by this CFD model. Moreover the CFD model of the gas-saving burner S-10 can be applied to improve the thermal efficiency of the burner in the future.
