Process forming can produce use by semi-automatic heat setting at 140°C at time of 70 seconds per piece is suitable for further expansion to create industrial handicrafts for the community.

Increasing concentrations of CO2 in the atmosphere is causing severe environmental destruction to the earth. Bio-sequestration of CO2 is a promising way to completely sequester CO2 by converting it into biomass by way of photosynthesis. The current research focused on biomass productivity and CO2 sequestration efficiency using microalgae. The experiment choose Spirulina sp. RMUTL by cultivating in working volume 8 liters bioreactor with zarrouks medium for 24-hrs with light nature and aeration air. The CO2 (100%) was flushed into the medium with a flow rate were 0.01 0.02 and 0.03 vvm respectively. The period of all experiments were 30 days. The results showed that the maximum specific growth rate OD560 algae biomass productivity efficiency of CO2 reduction CO2 fixation rate and carbon loading rate were 0.35±0.01 d-1 0.85±0.00 600.00±10.00 mg.L-1 96.83±0.76% 1 128.00±18.80 mg.L-1.d-1 and 2 0 . 4 1 ±0 . 2 6 g. d-1 with 0.01 vvm CO2 flow rate. The average CO2 sequestration over 30 days were 3.15.±0.03 3.11.±0.02 and 3.07.±0.07% in 0.01 0.02 and 0.03 vvm CO2 flow rate respectively.

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.

Deterioration of reinforced concrete deep beam structure caused by chloride is severe andtakes up wide area even though the structure is not exposed to sea water or brackish water. Even the structure which is far from sea water or brackish water is affected by this problem.When the reinforced concreate deep beam structure is affected by chloride steel reinforced inside the structure is corroded resulting in reducing the cross-sectional area of the reinforced steel affecting load capacity deflection and beam failure. If there is no repair or strengthening such capabilities are continuously reduced until it is no longer safe to use the beam. Therefore it is necessary to repair or strengthening the deteriorated structure to be safely used. This research investigated strengthening of deteriorated reinforced concrete deep beam caused by chloride with 4 formats of carbon Fiber sheets to seek guidelines for the most efficient strengthening. The resultshowed that the strengthening by the 4 format of carbon fiber sheet could increase ultimate loadcapability yet could not improve ductility of the deteriorated beam to become close to the beamthat is not deteriorated. The strengthening that could increase the maximum ultimate load capability was the table format strengthening. In addition the strengthening that the carbon fiber making 45 degrees with the length of the beam could best prevent diagonal cracks.

This study investigated the effects of partial replacement of wheat flours with Hom Nil rice flour on the physicochemical characteristics antioxidant activities and sensory acceptance of chinese steam bread (Mantou). Mantou was made with wheat flours partially substituted with Hom Nil rice flour at the level of 0% 10% 20% and 30%. Colour parameters (lightness (L*) redness (a*) and yellowness (b*)) of Mantou were measured using a Hunter colorimeter and found that L* andb* values of Mantou decreased while a* value increased with increase in level of Hom Nil rice flour from 0 to 30%. Physical characteristics including hardness springiness and cohesiveness of Mantou were significantly affected with substitution due to the disruption of dough structure. The hardness of Mantou increased with the increasing of the Hom Nil rice flour substitution (0%-30%) in contrast with springiness and cohesiveness. The total phenolic/anthocyanin contents and antioxidant activities (DPPH FRAP and ABTS) of Mantou increased with increasing Hom Nil rice flour level up to 30%. These results suggested that the substitution of 20 % Hom Nil rice flour would produce healthy and acceptable Mantou with higher total phenolic/anthocyanin contents and antioxidant activities.
