The morphology showed interconnected spongy spheres and polygons shapes with a pore size of 14.144 ± 11.31 and 19.4822 ± 18.71 micrometers, respectively. The formula ratio of fibroin: gelatin of 8:2 contained more random coil, while the formula ratio of fibroin: gelatin of 7:3 exhibited more β-sheet structure. The result revealed that gelatin influences fibroin conformational transition from random coil to beta, which might result from better hydrophobic characteristics. The surface of the formula ratio of fibroin: gelatin at 8:2 and 7:3 was 125.88 ± 9.85 and 130.07 ± 3.72 degrees, indicating the formula ratio of fibroin: gelatin at 7:3 had more hydrophobicity than the formula ratio of fibroin: gelatin at 8:2. The biocompatibility of scaffolds was determined for both formulas of human keratinocyte (HaCaT) and African green monkey kidney (Vero) cell lines by MTT assay. The formula ratio of fibroin: gelatin at 8:2 with various concentrations of 62.50, 125, 250, 500, and 1,000 µg/mL had cell viability percentages of 96.31, 101.74, 97.81, 104.15, and 103.22%, respectively. The formula ratio of fibroin: gelatin at 7:3 with various concentrations of 62.50, 125, 250, 500, and 1,000 µg/mL had cell viability percentages of 106.38, 104.28, 108.54, 97.42, and 97.65%, respectively. The growth of cell lines showed better performance with the hydrophilic characteristics of the scaffold, and it did not make it toxic to the HaCaT and Vero cell lines. These results demonstrated the possibility of gelatin-blended scaffold as a supporting material for skin tissue engineering, especially for wound healing.

The rind makes up about 60-75% of whole fruit and is often discarded. Here, we evaluated the effect of durian rind, specifically the inner white peel, as a supplement for a fish diet on the growth performance and disease resistance against Aeromonas hydrophila in Red Tilapia. Fish with an initial average weight of 42.68 ± 0.11 g were fed diets supplemented with durian rind at 0, 10, 15, and 20% for 140 days. Subsequent results showed that growth performance in terms of weight gain, average daily gain, length gain, and specific growth rates were not significant among treatments (P > 0.05). In addition, the feed conversion ratio and survival rate of fish fed with diets supplemented with durian rind were also not significantly different from the control (P > 0.05). After the 140-day feeding trial, fish were injected intraperitoneally with A. hydrophila, and the cumulative mortality was recorded for 14 days. The survival rate of fish-fed durian rind-supplemented diets at all levels was higher than that of the control. The highest survival rate and relative survival percentage were fish fed with 10% and 15% durian rind in the diet. Taken together, the white peel of the durian rind can be a potential fish feedstuff and can act as a natural antibiotic to improve fish resistance against A. hydrophila. Recommended level of durian rind supplementation is 10%-15% in the diet which will not affect growth but can enhance disease resistance to A. hydrophila.

Full fertilizer is applied two weeks after planting for the vegetative growth period. Apply another set of fertilizers containing a combination of nitrogen and potassium during the bulking period one and a half months later; this is one way to give the tuber a sweetened flavor. Because fresh sweet potato tubers are more marketable if their sizes are more or less consistent, the study hypothesized that ceasing to apply fertilizer containing phosphorus will adversely affect the uniformity of the size of sweet potato tubers. The application of mixtures of muriate of potash and urea-containing fertilizer increased sweet potato tubers with the highest average circumference and the average weight in Treatment 2 [Circumference (C)=12.4 cm; weight (W)=0.35 kg], which demonstrates the elimination of phosphorus-containing fertilizer for the bulking period of sweet potato production. According to the one-way analysis of variance (ANOVA) and F test (F = 1.09, p = 0.41), there was no statistically significant difference in the dependent variable between the various groups. The study finds that using muriate of potash and urea-containing fertilizer combinations generated the maximum yield in terms of circumference and weight per tuber for sweet potato farming with semi-loam varieties (Treatment 2). The usual application of the farmers under study to Treatment 2 is to reduce the use of synthetic fertilizers.

Downdraft gasifiers are famous for engine applications and used for thermal applications. The product gas has to meet the individual requirements of different end users or applications. The downdraft gasifier based on open core throat less design has been developed according to its suitability for small-sized biomass. The preliminary experiment investigated gasifying characteristics by studying the temperature distribution within the gasifier. This study used three kinds of biomass: Eucalyptus wood chip, Mimosa wood twig, and wood pellet. The results showed that the temperature distribution within the gasifier for each zone corresponds with the character of the gasifying process within the downdraft gasifier. Moreover, the temperature profiles for a gasifying process for all three biomass tests were in the same pattern. The maximum temperature was in the combustion zone (T3). The maximum temperature at the combustion zone for the Eucalyptus wood chip is the highest compared with the maximum temperature at the combustion zone of the Mimosa wood twig and wood pellet. The temperature at the combustion zone (T3) of the Eucalyptus wood chip, Mimosa wood twig, and the wood pellet were 838, 783, and 620 °C, respectively. The temperature at the combustion zone results in the temperature at the reduction zone. The average temperature at the reduction zone for gasifying all three biomass feeds ranges from 470-514 °C. While the temperature at the pyrolysis zone and the gas exit are not significantly different for all three biomass feeds. These results showed that the reaction within the gasifier could carry out continuously with a suitable temperature in each zone as per the design.\u0000 ","PeriodicalId":426475,"journal":{"name":"ASEAN Journal of Scientific and Technological Reports","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128661257","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}

This study evaluated chili plants' responses regarding physiological traits, growth, yield, and capsaicin content under different irrigation levels. The experimental design was a 2x4 factorial in CBD. A pot experiment was conducted on two species of chilies: Capsicum annuum ‘Super-Hot 2’ and ‘Huay-Siiton’ and C. frutescent ‘Prik-Kee-Nu-Suan.’ The plants were irrigated at four watering regimes such as 100%, 80%, 60%, and 40% of maximum water holding capacity (MWHC) after the anthesis through fruit development. Midday leaf water potential (LWPmd) was ranked between -1.30 MPa in 100% MWHC to -2.11 MPa in 40% MWHC indicating the level of water stress. The 40% MWHC caused a drastic decrease in LWPmd and reduced the maximum quantum yield of PSII (Fv/Fm) and growth rate in canopy width. Observed leaf greenness was maximized at 60% MWHC. The irrigation regimes also affected the yield of chili, especially the 60% and 40% MWHC, with a reduced number of fruits/plant, fruit fresh and dry weights, and fruit sizes. In the case of 40% MWHC, the dry yield was too low, and it was impossible to analyze the capsaicin content. The reduced irrigation (80% and 60% MWHC) did not significantly induce the capsaicin content or pungency of the studied chili cultivars. Thus the capsaicin yield of studied chili cultivars was reduced considerably by severe reduction of dry fruit yield under restricted water.","PeriodicalId":426475,"journal":{"name":"ASEAN Journal of Scientific and Technological Reports","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132626451","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}
