ABSTRACT Gamma irradiation was used to reduce the N‐nitrosamines and residual nitrite in model system sausage during storage. Aerobic or vacuum packaged irradiated at 0, 5,10, 20, 30 kGy. The levels were significantly reduced by gamma irradiation, and, packaging, reduction dose dependent. N‐nitrosodimethylamine of 10 kGy above aerobic while a 20 needed packaging. N‐nitrosopyrrolidine found kGy‐irradiation. Results indicated that high (> kGy) carcinogenic N‐nitrosamine pork
ABSTRACT: Irradiation effects on biogenic amines (BAs) and microbiological populations of Korean fermented soybean paste were investigated during fermentation. Soybean was prepared irradiated with doses 5,10, 15 kGy, then at 25 °C for 12 wk. Bacillus spp. lactic‐acid bacteria decreased by irradiation but increased Biogenic detected putrescine, cadaverine, β‐phenylethylamine, spermidine, spermine, tryptamine, histamine, tyramine, agmatine. A significant difference not observed in BA content...
ABSTRACT: Gamma irradiation was applied for the breakdown of volatile N‐nitrosamines (VNAs), nitrosodimethylamine (NDMA), and nitrosopyrrolidine (NPYR). NDMA NPYR were dissolved in distilled water, dichloromethane, or ethanol, irradiated at 2.5, 5.0, 7.5, 10, 15, 20, 25 kGy by gamma ray. Samples analyzed GC‐TEA. water dichloromethane easily broken 5 above. most sensitive to irradiation, while is relatively resistant irradiation. ethanol 90% above 20 kGy. VNA formation not observed vitro test...
The CuS anode enables spontaneous transformation into a porous nanostructure and the formation of conductive Cu nanoparticles. These features conversion for Na-ion batteries exhibit remarkable electrochemical performance.
ABSTRACT: Shrimp ( Acetes chinensis ) were sliced, washed, and then salted with 15 20% (w/w) sodium chloride. Salted shrimp was 0, 5, 10 kGy‐irradiated at 2 different stages: 1) irradiated immediately after processing shrimp, 2) optimum fermentation period, fermented °C for weeks. Nonirradiated 30% salt also prepared as a control. Irradiated not in proximate composition, salinity, water activity from nonirradiated the same addition irradiation time. During fermentation, volatile basic...
ABSTRACT: Free radical scavenging and antioxidant activities of irradiated phytic acid at various concentrations were studied. Phytic sodium salt dissolved in deionized distilled water was 0, 5, 10, 15, 20 kGy. The degradation by irradiation observed, it found that the had an effect on degree degradation. Stable 2,2‐diphenyl‐1‐picrylhydrazyl ability significantly increased ( P < 0.05) positively correlated with dose 0.01). Antioxidant activity lipid model systems slightly irradiation;...
It is important to apply the Length types of Processed Rebar Simplification (LPRS) rebar work for improving efficiency and reducing labor in construction fields. However, when used excessively, LPRS can also bring about adverse results, as increase amount wasted rebars scale with cutting process, leading an material cost. Therefore, it crucial find a proper level simplification considering cost together. In this study, various tests were conducted based on BIM software quantitatively...
Application of Machine Learning Technology for Construction Site Heejae Ahn, Dongmin Lee, Seongsoo Taehoon Kim, Hunhee Cho and Kyung-In Kang Pages 126-133 (2018 Proceedings the 35th ISARC, Berlin, Germany, ISBN 978-3-00-060855-1) Abstract: Although several research studies on application machine learning to construction field are actively underway, no study has yet been done areas where is primarily needed. Using importance-performance analysis method, this paper identified top five sites...
