This research aims to investigate and test the feasibility of the production of natural teak sheets and study the appropriate production methods. Study physical properties and mechanical properties to compare with industry standard insulation sheet. The ratio of tattoo and hyacinth. 5% 7% 9% of the material were dried at 400 600 800 kg / m3. The results showed that the modulus rupture. Elastic modulus And thickness swelling. It varies with the amount of glue. The nature of the tattoo causes absorption in the material if the density increases the water absorption will decrease. Compared to standard insulation products. The amount of adhesive is 7% of the weight of the material when dry. The density of 800 kg / m 2 is 25 kg / cm2. 140 degree Celsius ruptured modulus and elastic modulus But the thickness of the swelling has not met the criteria. In the next production should be mixed waterproofing in the work.

In this research scaffolds of β-tricalcium phosphate (β-TCP) and zinc nickel ferrite (ZnxNi1-xFe2O4) were simply fabricated via the uniaxial pressing together with pressureless sintering which can be tailored for specific applications. The morphology of ZnxNi1-xFe2O4/β-TCP scaffolds with all formulas obtained from the SEM result revealed the larger grains the higher porosity and higher interconnectivity with increasing of ZnxNi1-xFe2O4 amount in β-TCP matrix. The high porous structure of the composite scaffold provided high surface area for cell attachment indicative of good cell growth and differentiation. Biological in vitro test using direct contact method with human cells revealed that the composite scaffold of β-TCP and Zn0.8Ni0.2Fe2O4 with all ratios induced the higher growth of Human osteoblast cells and the better cell spreading on surface of specimens

This study of the role of family locals and community in enhancing the quality of elderly people’s lives in central area by means of Sufficiency Economy theory collected the data from people. It aims 1) to study the role of family locals and the community to enhance the quality of elderly people’s life in Thailand’s central region; 2) to analyze factors related to the quality of elderly people’s lives; and 3) to identify ways of encouraging the development of elderly people to prepare them to be part of the society of elderly people in the ASEAN region. The participants in this research were elderly people in the central region. The research used quantitative methods to measure quality of life. Multi-stage sampling was employed. The data were analyzed with descriptive statistics such as average (x̅) and standard deviation to investigate the elements of each factor in the study. The results from the focus group regarding the quality of elderly people’s life can be summarized as follows: 1) The development of the quality of life of elderly people is based on the concept of “Strong community and people through the development and adaptation of the theory of the Sufficency Economy”. 2) The development of the quality of elderly people’s lives by means of religion: emphasizing the Buddhist way of life and local wisdom and culture to teach family members to be a grateful and loyal and to be a good person for the family and local community. 3) The quality of life of elderly people can be improved by implementing laws informed by morality to encourage generosity between family locals and community to solve the problems of elderly people. 4) The quality of life of elderly people locals and the community is based on mutual respect living together naturally according to the concept of the Sufficiency Economy in order to support large numbers of elderly people in the future. Suggestions arising from this research and from other ideas from participants include increases in government funds budgeted to support elderly people and the creation by local government of projects and activities for elderly people. In addition the participants also perceive the need for a chance for the elderly to study and learn in the local elderly school without age limit as a form of life-long learning. The participants also suggested the idea of evaluating the systems of schools for elderly people according to the “cheerfulness and happiness” of learners rather than by any other method. Connections between the schools for elderly learners in the central area should be co-ordinated so as to create more projects and activities.

This research aims to study phytochemicals and potential of Mapok (Parinari anamense Hance) extracts to inhibit germination and growth of Barnyard grass (Echinochloa crus-galli) a common weed in the rice fields. Organic solvents extracted the part of fruits barks and leaves of Mapok included hexane ethyl acetate and methanol. Crude extracts compose of fruit hexane extract fruit ethyl acetate extract fruit methanol extract bark hexane extract bark ethyl acetate extract bark methanol extract leaves hexane extract leaves ethyl acetate extract and leave methanol extract. Crude extracts were tested of phytochemical tested of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition of Barnyard grass. Leaves ethyl acetate extract showed highest inhibit germination and growth of Barnyard grass The leave ethyl acetate extract was separated by column chromatography to yield nine fractions (F1 – F9 fraction) and tested inhibit germination and growth repeating. The results showed that 1. The crude ethyl acetate extracts from the bark of Mapok at a concentration of 3000 ppm showed the highest inhibited percentage of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition. 2. Fraction F8 of leaves ethyl acetate extract showed the highest inhibited percentage of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition.

The development of lightweight flat sheet prototype from para rubber leaves and para para rubber wood fly ash for field work application can offer an alternative method of adding value to agricultural wastes and help to conserve the environment with green products. The natural fiber especially agricultural waste fiber is an encouraging prospect. Natural fiber composites have been used for building applications. The aim of this research was to investigate the potential use of para wood ash to producing a cement composite as an environmentally material. Material. The cement paste with 5-2 % weight of para wood ash. The specimens were cured at 25± 2 oc for 24 hours. The properties of cement composites mixed with different proportions of para wood ash were compared with Ordinary Portland Cement (OPC). In addition the morphology of para wood ash was examined by using scanning electron microscope. The density increased with the increase in the percentage of para rubber leaves from 1% 2% 4% and 6%. The finding is attributable to the enhanced packing density by the fine para wood ash particles size was found 5-10 um.Moreover para wood ash particles could arrange to fill the inter-particle voids in cement pastes which resulting to increase the compressive strength of cement paste. Consequently para wood ashes could incorporate in the construction materials to enhance the mechanical properties and durability performance of the cement composites
