    วารสารวิชาการและวิจัย มทร.พระนคร, ปีที่ 14, ฉบับที่ 2 (ก.ค.-ธ.ค. 2563), หน้า 1-17Water is a vital component of almost every organism. Magnetic fields effecting on physical properties of water are reported in this work. In order to obtain the magnetized water, magnetic fields were applied and subsequently passed through water. The chemical properties of magnetized water were also studied such as pH, dissolved oxygen gas, spectroscopic data of UV-, X-ray and IR-spectrum, calcium carbonate crystallization, concrete strength, levitation, refractive index, melting point, contact angle, electrolytic potential value, hydrogen bonding, vaporization, conductivity, flow rate, dielectric constant, viscosity, surface tension, total hardness, convection, Ac magnetic susceptibility and diffusion. In addition, the magnetized water affecting the growth of some plants and mice with antineoplastic drugs were also studied.Rajamangala University of Technology Phra Nakho

    วารสารวิชาการและวิจัย มทร.พระนคร, ปีที่ 14, ฉบับที่ 2 (ก.ค.-ธ.ค. 2563), หน้า 198-209. This research aimed to study the acidification processes of carving vegetable using acid conditioning machine under emperature and pressure control which was developed in this study. Four acidification procedures were done at normal atmospheric pressure (method 1), under vacuum pressure for 10 (method 2) and 20 min (method 3) and vacuum pressure alternating with normal atmospheric pressure for each of 1 hour. There were two main parts of acid conditioning machine including the temperature controller inside the pickle tank and heat conductor tank, and the pressure controller inside the pickle tank. The pickling temperature was stabled at 40oC under the pressure of 0.5 Bar. PLC (Programmable Logic Controller) program was used to write the ladder for controlling all processes and display through SCADA system. The results showed that the acidification method by soaking the carved-rose carrot under vacuum pressure alternating with normal atmospheric pressure showed the shortest time to equilibrium by 7 hours. Then, the carved-rose carrot was packed in the glass jar followed by sterilized in boiling water for 15 minutes and stored at room temperature for 7 days. Total bacteria count, Escherichia coli and Yeast-mold were not exceeded than the standard limit. Staphylococcus aureus was not detected throughout the storage periodsRajamangala University of Technology Phra Nakho

    วารสารวิชาการและวิจัย มทร.พระนคร, ปีที่ 14, ฉบับที่ 1 (ม.ค.-มิ.ย. 2563), หน้า 165-176The 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.Rajamangala University of Technology Phra Nakho

The average duration of waiting for each service was 11-30 minutes. An influential person for purchase decision was oneself. They used the service for dinner, during Saturday – Sunday. The frequency of using the service was about once per month and the average cost per person was 101-400 baht per time. Service marketing mix factors affecting the decision to select Bangkok restaurants receiving Bib ourmand awarded by Michelin for both overall and individual aspects were at a high level. Decision-making process affecting the decision to select Bangkok restaurants receiving Bib Gourmand awarded by Michelin for both overall and individual aspects were at a high level. In terms of comparing demographic characteristics, the respondents with different age, occupation, monthly income, and marital status had different decision to select Bangkok restaurants receiving Bib Gourmand awarded by Michelin with a statistical significance level of 0.05. In addition, service marketing mix factors were moderately positively related with the decision-making process affecting the decision to select Bangkok restaurants receiving Bib Gourmand awarded by Michelin. When individual aspects were considered, six factors, including product, place, promotion, people, process, and physical evidence were moderately related with the decision-making process. However, price was related with the decision-making process at a low level.Rajamangala University of Technology Phra Nakho
