This study was to develop a processing method for improving the quality of a fermented soybean food, cheonggukjang. Bacillus sp. AS-2 isolated from traditionally fermented cheonggukjang was selected for the production of cheonggukjang with the rotative fermentation method (RFM). The pH value of cheonggukjang made by RFM (cRFM) was 6.1±0.25. The amount of crude protein (329.0±0.92 mg/g) and amino-type nitrogen (120.6±21.81 mg%)
were similar to those in traditionally fermented cheonggukjang (cTFM). The amount of ammonium-type nitrogen was 173.0±1.72 mM/g and nearly 4 times lower than that in cTFM. 1,1-Diphenyl-2-picrylhydrazyl
(DPPH) radical scavenging values in the traditional product were between 1.62±0.08 and 1.27±0.05, while with the RFM, the
values were between 1.38±0.02 and 0.78±0.20. The antioxidative activity of the sauce-type cRFM was approximately 1.7 times
higher than that of cTFM. The sensory scores for cRFM were uniformly higher than those for cTFM. 相似文献

Previous studies have demonstrated the importance of joint angle errors mainly due to skin artifact and measurement errors
during gait analysis. Joint angle errors lead to unreliable kinematics and kinetic analyses in the investigation of human
motion. The purpose of this paper is to present the Joint Averaging Coordinate System (JACS) method for human gait analysis.
The JACS method is based on the concept of statistical data reduction of anatomically referenced marker data. Since markers
are not attached to rigid bodies, different marker combinations lead to slightly different predictions of joint angles. These
different combinations can be averaged in order to provide a “best” estimate of joint angle. Results of a gait analysis are
presented using clinically meaningful terminology to provide better communication with clinical personal. In order to verify
the developed JACS method, a simple three-dimensional knee joint contact model was developed, employing an absolute coordinate
system without using any kinematics constraint in which thigh and shank segments can be derived independently. In the experimental
data recovery, the separation and penetration distance of the knee joint is supposed to be zero during one gait cycle if there
are no errors in the experimental data. Using the JACS method, the separation and penetration error was reduced compared to
well-developed existing methods such as ACRS and Spoor & Veldpaus method. The separation and penetration distance ranged up
to 15 mm and 12 mm using the Spoor & Veldpaus and ACRS method, respectively, compared to 9 mm using JACS method. Statistical
methods like the JACS can be applied in conjunction with existing techniques that reduce systematic errors in marker location,
leading to an improved assessment of human gait. 相似文献

A bioengineered spinal cord is fabricated via extrusion‐based multimaterial 3D bioprinting, in which clusters of induced pluripotent stem cell (iPSC)‐derived spinal neuronal progenitor cells (sNPCs) and oligodendrocyte progenitor cells (OPCs) are placed in precise positions within 3D printed biocompatible scaffolds during assembly. The location of a cluster of cells, of a single type or multiple types, is controlled using a point‐dispensing printing method with a 200 µm center‐to‐center spacing within 150 µm wide channels. The bioprinted sNPCs differentiate and extend axons throughout microscale scaffold channels, and the activity of these neuronal networks is confirmed by physiological spontaneous calcium flux studies. Successful bioprinting of OPCs in combination with sNPCs demonstrates a multicellular neural tissue engineering approach, where the ability to direct the patterning and combination of transplanted neuronal and glial cells can be beneficial in rebuilding functional axonal connections across areas of central nervous system (CNS) tissue damage. This platform can be used to prepare novel biomimetic, hydrogel‐based scaffolds modeling complex CNS tissue architecture in vitro and harnessed to develop new clinical approaches to treat neurological diseases, including spinal cord injury. 相似文献

Supercritical water oxidation (SCWO) was carried out in a flow-type reactor for modeling of waste-water containing phthalic
or adipic acid. For each acid, the reaction order and rate constant, k, were determined over a wide range of experimental
conditions : temperatures from 633.15 to 713.15 K, pressures from 18 to 29 MPa, excess amounts of hydrogen peroxide from zero
to 800 percent, and the mean residence time in the reactor from 1.1 to 49.1 seconds. The concentration of both acids in model
wastewater was set by 500 ppm. For phthalic acid, we found that the orders of decomposition reaction with respect to the reactant
concentrations were 0.56 for phthalic acid, 0.31 for hydrogen peroxide, and 0.53 for water. For adipic acid, the orders of
oxidation were 0.78 for adipic acid, 0.53 for hydrogen peroxide, and 0.74 for water. Then measured activation energy for phthalic
acid was 33.08 kcal/mol and that for adipic acid was 19.51 kcal/mol, respectively. 相似文献

An Embedded Web Server (EWS) is a Web server which runs on an embedded system with limited computing resources to serve embedded Web documents to a Web browser. By embedding a Web server into a network device, it is possible to provide a Web‐based management user interface, which are user‐friendly, inexpensive, cross‐platform, and network‐ready. This article explores the topic of an efficient and lightweight embedded Web server for Web‐based network element management. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献

The influence of different water types and brewing durations on the colloidal properties of green tea infusion 下载免费PDF全文

Green tea infusions were prepared with three different water types: distilled water, commercial mineral water and CaCl2 added distilled water (at 20 mg L?1). The impact of different water type on the colloidal particle parameters, namely size, polydispersity index (PDI) and zeta potential, was examined within 24 h. Our results indicate that distilled water green tea infusion (DWT) brewed at 80 °C for 5 min contained the smallest particles (242.17 ± 11.78 nm) as examined by dynamic light scattering (DLS). Moreover, DWT showed smaller size increase during the 24 h storage than that of mineral water tea and CaCl2 added water tea infusion. The morphology characteristics of green tea infusion particles were visualised by transmission electron microscope (TEM) which revealed that green tea infusion particles had heteromorphic shapes. Our results suggest that mineral composition of water impacts the colloidal size and stability of green tea infusion. Additionally, DLS and TEM could be useful tools to provide colloidal information which is important to understand quality characteristics of green tea infusion during processing and storage. 相似文献

Bioactive properties of enzymatic hydrolysates from abdominal skin gelatin of yellowfin tuna (Thunnus albacares) 下载免费PDF全文
Yuna Han Sang‐Hun Byun Joung‐Hyun Park Seon‐Bong Kim 《International Journal of Food Science & Technology》2015,50(9):1996-2003
Gelatin (90.6 ± 0.1%) was optimally prepared by response surface methodology from yellowfin tuna (Thunnus albacares, YT) abdominal skin. To investigate bioactive properties of enzymatic hydrolysates from the abdominal skin gelatin (ASG), ASG was hydrolysed with alcalase, protamex, neutrase and flavourzyme as affected by hydrolysis time. Antioxidant, nitrite scavenging and angiotensin‐I converting enzyme (ACE) inhibitory activities of the hydrolysates were determined. Antioxidant activities of the hydrolysates were found through linoleic acid peroxidation inhibitory effects. Alcalase‐derived hydrolysates (AHs) were more effective than others in metal ions chelating, superoxide anion scavenging and hydroxyl radical scavenging activities (P < 0.05). AHs showed significantly stronger nitrite scavenging activities (44.4–60.7%) than others (P < 0.05). Fraction A from AH showed strong ACE inhibitory activity (IC50 of 0.75 mg mL?1). These results suggest that YT ASG and its enzymatic hydrolysates could be functional food and/or pharmaceutical ingredients with potent antioxidant, anticarcinogenic and antihypertensive benefits. 相似文献
