Effect of drying temperature (50, 60 and 70 ° C) on the total antioxidant activity (TAA) of the obtained crude extracts was investigated using the DPPH method at various pH conditions (4.0, 6.5 and 8.5). Results showed that the crude extract obtained from the drying temperature of 50°C and testing condition at pH 4.0 had the highest TAA value. However, there was interaction between drying temperature and pH conditions, thus the treatment at 50°C, pH 6.5 and 70°C, pH 4.0 was not significant different.The relationships between temperature and pH on TAA were explained using the multiple regression (R 2 =0.987). The crude extracts caused changes in texture properties of gummy jelly indicated by decreases in gumminess and chewiness of the products. Result was consistent with the results obtained from sensory evaluation (9-points hedonic scale) that sensory texture (springiness and toughness) and color scores decreased. This study suggested that the extraction of Psidium guajava Linn. leaf has the potential to be used as antioxidant supplements and it can be used in gummy jelly products.","PeriodicalId":352801,"journal":{"name":"King Mongkut’s University of Technology North Bangkok International Journal of Applied Science and Technology","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115164158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To investigate the effect of the textile parameters on the surface development organic sheets with different steel wire fabrics and a polycarbonate matrix were manufactured using a laboratory press. The fabrics differed in fiber diameter and mesh size. The results showed that both textile parameters have a significant influence on the characteristic surface waviness of the FRPC. Increasing fiber diameters and mesh sizes lead to higher maximum waviness. Organic sheets with a fiber diameter of the reinforcement less or equal 50 μm could not be differentiated anymore and had no visible waviness. Based on the equation for linear thermal expansion a thermo rheological process model was developed to predict the surface waviness. The model describes the waviness creation including a pressure induced compensating polymer flow. A waviness comparison of experimental data with calculated results shows a good agreement.","PeriodicalId":352801,"journal":{"name":"King Mongkut’s University of Technology North Bangkok International Journal of Applied Science and Technology","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121399226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The in vitro low solubility of the fully folded proteins is relevant to applied microbiological studies, biochemical studies, biopharmaceutical studies, high-resolution structural studies, and applications demanding high protein concentration. This insufficient protein solubility depends largely on the surface property of the protein molecule. To alleviate this problem, approaches emphasized on the improvement of water-binding ability or prevention of protein aggregation were employed including the use of chemical additives, fusion with solubility enhancement tags, and molecular engineering of the surface amino acid residues. With the availability of the three-dimensional structure of the target proteins, the effect of different surface amino acid residues on protein solubility could be systematically investigated. With the applications of advanced bioinformatics tools and guided by protein three-dimensional structure, solubility-improving mutagenesis can be designed and executed with a high chance of success. Integrating rational molecular engineering with other available approaches will be the effective strategy for alleviating in vitro low solubility of important proteins in the future.","PeriodicalId":352801,"journal":{"name":"King Mongkut’s University of Technology North Bangkok International Journal of Applied Science and Technology","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129282359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A high-quality densified product is strongly desired, binding agents are usually added to comminuted biomass material to improve the quality of the resulting briquettes. Many materials naturally possess such binding agents; however, they may not be enough or available in a form that can contribute to product binding. The briquettes were prepared from groundnut shell with different cassava starch as binder in varying percentage (5, 10, 15 and 20%) by weight. The prepared briquettes after sun drying for 21 days were subjected to water boiling test for assessing the quality and suitability of briquetted fuel as domestic fuel. The groundnut shell briquettes burnt with good flame and observed 14.47 to 18.46% thermal efficiency while that of wood is 10.31%. The average burning rate of the briquettes ranges between 0.587 and 0.881 kg/hr while that of wood (V) is 1.166 kg/hr. The average specific fuel consumption of the briquettes ranges between 0.067 and 0.267 J/g while that of wood is 0.332 J/g. The boiling time for briquettes is between 14.80 to 23.15 minutes and 13.05 to 19.08 minutes for cold and hot start respectively while for wood are 28.05 and 19.20 minutes for cold and hot starting respectively. Comparatively briquette with 20% binder performs better.","PeriodicalId":352801,"journal":{"name":"King Mongkut’s University of Technology North Bangkok International Journal of Applied Science and Technology","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123558216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The packing efficiency of this column was developed by changing the packing material. Packing efficiency is normally an important key index, especially after a revamp. Aspen Dynamic was used to generate the best procedure for the start-up operation, covering three variables: the distillate rate, the reflux rate and the bottom rate. The start-up procedure according to these three parameters was divided into six scenarios. In addition, the effect of reflux rate and feed location was the operating conditions, including temperature profile of the column, benzene concentration in the overhead stream, and liquid levels in the reflux drum and sump. The test run data matched well, with 0.6 Murphree efficiency. The optimal procedure for the start-up operation was found to be a distillate rate – bottom rate – reflux rate scenario, which took just 9 h to reach a steady state.","PeriodicalId":352801,"journal":{"name":"King Mongkut’s University of Technology North Bangkok International Journal of Applied Science and Technology","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122021055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
