Study of Ozone Generator with Electric Fields Distribution on Water Surface
This paper proposes a study of an Ozone generator. The generator under the study is designed using the electrode with uniform field. The electrode is constructed in the plane shape with positive potential. The transformer oil is used as insulating materials to prevent discharges around the electrode discharges in the air void depends on the size the types of dielectrics and level of applied voltage. Between the electrode and the air void there is acyclic dielectric. The stainless electrode with water is used as a ground potential. The breakdown depends on the electric field intensity. It is found that there is sufficient amount of ozone due to the ionization Development and design ozone generator this research electric field intensity on the water type and this can be used as a principle to construct a new type of ozone generator.
Risk Assessment of Damages for Equipments in the Building
This paper presents risk assessment of damages for equipments in the building based on IEC standards and ITU-T recommendations. The study of risk assessment of damages for equipment in the building includes of 6 main topics: calculation of frequency of damages due to lightning discharges calculation of risk of damage calculation of risk areas estimation of probability factors consequential damage factor acceptable risk levels and mitigation methods to reduce the influence of power line induction affecting to equipment. Also the implementations of surge protective devices (SPDs) at the entrance of power lines into the building contribute to a further decrement of damage.
The Ethical Behaviors through Students Perception in the Field of Business Administration in Rajamangala of Technology University Phra Nakhon
The purposes of the research were to study ethical behaviors through business administration’s students perception in the field of in Rajamangala university of Technology Phra Nakhon in the following aspects: honesty discipline favor responsibilities diligence selfhelp and gratefulness. The sample groups were 300 students of Business Administration. The results were as the following: the ethical behaviors were at a moderate level. When compared by gender it was found that there was statistically significant differences at .05. When compared by achievement it was found that there was significant differences at .05.
การเปลี่ยนแปลงคุณภาพไข่เค็มพอกขมิ้นทดแทนดินจอมปลวกบางส่วนระหว่างการเก็บรักษา
This research aimed to study the quality changes of coating salted eggs partially replacing soil from termite mound with turmeric powder at the level of 0% 5% 15% and 25% during storage for 4 weeks. The results showed that the increasing in turmeric level caused a decrease in salt content in raw egg yolk and raw egg white which led to decrease in hardening ratio of egg yolk. The hardness values of cooked - salted egg yolk decreased while those of cooked - salted egg white slightly increased. At the same salting period the color values of raw egg yolk and raw egg white coated with different levels of turmeric were slightly different. Egg yolks changed to a yellowish orange color while egg whites showed lightness with a direction of red and slightly yellowish color. The raw egg white coated with higher level of turmeric powder exhibited more yellowness which was in accordance with the increasing in curcumin content. From the results of 9-point hedonic scale in terms of color aroma overall taste and overall liking it was found that salted eggs coated with turmeric powder to partially replace soil at a level of 25% with 2 weeks of preserved duration had high scores of sensory acceptability which did not differ significantly from the control samples (0% turmeric) (p>0.05). The curcumin content analyzed in dry egg white was 3.885 mg/g at week 2 and increased to 13.291 and 18.484 mg/g at week 3 and 4 respectively.
ปัจจัยที่ส่งผลต่อความล่าช้าของโครงการก่อสร้าง
The research is aimed to 1) study the level and priority of the factors affecting the delay of construction projects and 2) provide suggestions in relation to the prevention of such delay. The sample is 520 people who were working for different construction projects. They were project managers project engineers field engineers and foremen. The data were collected by using online questionnaires and analyzed to find out mean standard deviation (SD) frequency correlation coefficient and confirmatory factor analysis. The findings reveal two significant aspects. First those who were working in the construction projects concerned about the factors affecting the delay of the projects at high level. Respectively the factors related to design resource external factors and others were taken into consideration. The factor regarding to work performance is regarded affecting the project delay at the highest level. Other factors i.e. the design external factors and others and resource have the affects at the lower level. Second the work-related factors can help prevent the project delay. In other words the construction plan and methods as well as the project management should be well-implemented in accordance with the design. The construction site should be on inspection considering its drawing. Regarding the external factors and others the public voices of those living around the construction site should be taken into consideration. Furthermore the effective use of the resources can be carried out by sufficiently preparing all materials tools and equipment for constructing any project effectively as a consequence.
