Use of waste ash from various by-product materials in increasing the durability of mortar
Use of waste ash from various by-product materials in increasing the durability of mortar

This paper presents a study on the strength and corrosion resistance of mortars made with binary blends of ordinary Portland cement (OPC) and ground rice husk ash (RHA) or ground palm oil fuel ash (POA). The mortar mixtures were made with Portland cement Type I containing 0-40% RHA and POA. RHA and POA with 1-3% by weight retained on a sieve No.325 were used. The water to binder ratio was kept constant at 0.5 and the flow of mortar was maintained at 110±5% with the aid of superplasticizer (SP). Scanning electron microscopy (SEM) was used for analysis. The compressive strength chloride penetration and corrosion resistance of the mortar were determined. The results show that strength as well as the resistance of mortar to chloride and corrosion can be improved by blending with RHA and POA. Thus RHA and POA have a high potential to be used as a good pozzolanic material.

This research aimed to study the use of coarse aggregate obtained from removing old recycled asphalt pavement (RAP) in the production of the porous concrete paving block. Crushing and size separation of the coarse aggregate by using standard sieve size by selected the gradation size of the coarse aggregate that passed to sieve size 1/2” and retained on sieve size 3/8” and other that passed to sieve size 3/8” and retained on sieve size No.4 by mixing ratio 50 : 50 of the mass as replaced natural coarse aggregate. Portland cement quantity about 18% and 20% by weight of the aggregate. The water to cement ratio was 0.30 and 0.35 respectively. Compressive strength flexural strength and water permeability were investigated. The results showed that the cement content and water to cement ratio was influenced the strength properties and water permeability rate of the porous concrete paving block. The porous concrete paving block mixed with higher cement content (20%) had the compressive strength at the age of 28 days increased by 16-24% when compared with lower cement content (18%). On the other hand the water permeability rate decreased by 5.1-8.1%.

Research on Creativity media promotion of cultural tourism. Traditional KUM-FAH Thai culture. Lopburi. The objectives of the research are as follows 1) For education and public relations media promoting cultural tourism Kam Fah tradition inherited Thai Phuan culture Lopburi 2) In order to develop the design and production of the public relations media model to promote cultural tourism the Kam Fah tradition continues Thai Phuan culture. Lopburi 3) In order to assess the satisfaction of the public relations media promoting cultural tourism the Kam Fah tradition continues Thai Phuan culture. Lopburi Method Will use quantitative and qualitative study together With research Gathering data from relevant documents textbooks and researches both academic and semi-academic. Before being introduced into the design and development process of new forms of public relations and packaging media Tools used to store data. The field. Asking for interviews informal interviews. Participatory Observation And the satisfaction rating of the new media and packaging. All data Is analyzed. A descriptive essay was also presented The research found that 1) The result of the satisfaction assessment of the new packaging for the target group The satisfaction is at the highest level with an average of 4.56 divided into 2 areas which are the structure design of the packaging The most satisfied with item 1 is the form of packaging structure Overall is suitable for the product. At the highest level with an average of 4.64 and packaging graphic design. The most satisfied with item 1 and no. 5 is a beautiful relaxing eye-catching style and packaging. The media / or identity of the Thai Phuan ethnicity can be used very well. At the highest level with an average of 4.80 2) The result of satisfaction evaluation of the new public relations media of the target group The overall satisfaction is at the highest level with an average of 4.36. The results from the sub-topics of the target group found that the target group has given attention / satisfaction with the public relations medianumber 1 is that they are satisfied with the form of New media releases as a whole The satisfaction was at the highest level with an average of 4.65

Effect of sweet basil ocimum basilicum l. leaves powder on qualities of pork emulsion sausage (Moo Yor)
Effect of sweet basil ocimum basilicum l. leaves powder on qualities of pork emulsion sausage (Moo Yor)

Effect of sweet basil (Ocimum basilicum L) leaves powder (SBP) (0.25-1.0%) on qualities and lipid oxidation of pork emulsion sausages (Moo Yor) during 21 days of refrigerated storage was investigated. Control sample had lower fiber content than samples added with SBP (p<0.05) at day 0 of storage. Samples treated with SBP (0.25-1.0%) had lowr L* value but higher b* value compared to the control samples (p<0.05). With the addition of SBP peroxide value (PV) and thiobarbituric acid-reactive substances (TBARS) value in the sausages were retarded effectively compared to the control sample (p<0.05) especially when the SBP at high contents were used. Samples treated with SBP had higher hardness compared with control sample during storage (p<0.05). SBP had no detrimental effect on the sensory attributes of sausages. Therefore SBP can be utilized in sausages to enhance shelf life quality.

This research aims 1) to study the relationship of human capital development to promote Thai traditional medicine in central north-eastern region 2) to analyze factors effect to human capital development to promote Thai traditional medicine in central north-eastern region 3) to synthesize the relationship of human capital development to promote Thai traditional medicine in central north-eastern region 4) to synthesize the quality of human capital to promote Thai traditional medicine in central north-eastern region. Research methodology is mixed-method in both quantitative and qualitative. Quantitative analysis data collected were 370 samplings from Thai traditional medicine in central north-eastern region; 4 provinces Kalasin Roi Et Mahasara Kham and KhonKaen between August 2017 – April 2018. Statistical analysis was by canonical method for testing dependent and independent variables. Sample was calculated under Krejcie and Morgan (Krejcie and Morgan 1970:608) against 1543 Thai traditional medicines in central north-eastern region. IOC for questionnaire testing validity and reliability were with alpha coefficient more than 0.70. Data analyzed by SPSS 20 calculated mean median mode standard deviation t-test and F-test statistics analysis using canonical correlation test for dependent and independent variables relation. Qualitative analysis data collected by in-depth interview from administrative of Thai Herbal institution the administrative of center of Thai traditional medicine for gathering and examining the quantitative previous data. The results are 1) human capital development has related to Thai traditional medicine for medical treatment in Thai traditional medicine course of study in low range 2) human capital development has related to Thai traditional medicine for medical treatment for practice experience in very low range 3) human capital development has related to Thai traditional medicine for medical treatment in Thai traditional medicine professional status in low range 4) factors influence to human capital development to promote Thai traditional medicine in medical treatment are government supporting policies and remuneration system 5) human capital development has related to Thai traditional medicine for medical treatment in knowing sickness knowing medicine capability of medical knowledge and knowing sickness originated that has related to course of study and certificate granted in medical treatment pharmacy midwifery and Thai massage in high range 6) human capital development has related to Thai traditional medical evolution in government supporting policies and remuneration in very high range.
