Effects of Different Salt Treatments on the Fermentation Metabolites and Bacterial Profiles of Kimchi 下载免费PDF全文
Dong Wook Kim Bo‐Min Kim Hyeon‐Jeong Lee Gwang‐Ju Jang Seong Hwa Song Jae‐In Lee Sang Bong Lee Jae Min Shim Kang Wook Lee Jeong Hwan Kim Kyung‐Sik Ham Feng Chen Hyun‐Jin Kim 《Journal of food science》2017,82(5):1124-1131
The effects of purified salt (PS) and mineral‐rich sea salt (MRS), both with different mineral profiles, on kimchi fermentation were studied using a culture‐dependent 16S rRNA sequencing technique and mass‐based metabolomic analysis. The different mineral profiles in the fermentation medium caused changes in the bacterial profiles of the 2 kimchi products. An increase of Leuconostoc species in MRS‐kimchi decreased the Lactobacillus/Leuconostoc ratio, which led to changes in metabolites (including sugars, amino acids, organic acids, lipids, sulfur compounds, and terpenoids) associated with kimchi quality. Although further studies on the relationship between these salt types and kimchi fermentation are needed, these results suggested that the MRS treatment had positively affected the changes of the kimchi mineral contents, bacterial growth, and metabolite profiles, which are linked to kimchi quality. 相似文献

A perfectly plastic material has been employed as a model material in simulation to analyze numerically the ring compression
process, especially to examine the deformation patterns along the die/workpiece interface, which is strongly related to the
frictional condition at the contact boundary. The main objective is to provide the deformation characteristics in detail in
ring compression, especially at the tool/workpiece interface. The surface flow patterns at the contact boundary in ring compression
are summarized and analyzed in terms of surface expansion, surface expansion velocity, pressure distributions exerted on the
die surface, relative sliding velocity between die and workpiece, and sliding distance along the die surface. Movement of
neutral positions and folding phenomenon are also investigated to see the effect on the deformation patterns at the interface,
that is, geometrical change, which is important to measure the frictional condition at the interface using calibration curves.
Finite element (FE) simulation using rigid-plastic finite element code has been performed for analysis. The results of this
study reveal that surface expansion as well as other surface flow patterns, such as sliding velocity and so on, shows different
and distinctive characteristics between low and high frictional conditions at the interface. This is directly related to the
movement of neutral positions and folding, which affects the sensitivity of dimensional changes to tribological conditions
at the interface. 相似文献

A fine patternable quantum dots (QDs) color conversion layer (CCL) for high resolution and full color active matrix (AM) micro‐LED (μ‐LED) display is demonstrated. QDs CCL could be patterned until 10 μm using photolithography process. It is found that multicoatings with red and green QDs (R‐ and G‐QDs) CCLs on LED array can provide full color AM display. 相似文献

The authors describe a new type of titanium (Ti) implant as a Modi-anodized (ANO) Ti implant, the surface of which was treated by sandblasting, acid etching (SLA), and anodized techniques. The aim of the present study was to evaluate the adhesion of MG-63 cells to Modi-ANO surface treated Ti in vitro and to investigate its osseointegration characteristics in vivo. Four different types of Ti implants were examined, that is, machined Ti (control), SLA, anodized, and Modi-ANO Ti. In the cell adhesion study, Modi-ANO Ti showed higher initial MG-63 cell adhesion and induced greater filopodia growth than other groups. In vivo study in a beagle model revealed the bone-to-implant contact (BIC) of Modi-ANO Ti (74.20% ± 10.89%) was much greater than those of machined (33.58% ± 8.63%), SLA (58.47% ± 12.89), or ANO Ti (59.62% ± 18.30%). In conclusion, this study demonstrates that Modi-ANO Ti implants produced by sandblasting, acid etching, and anodizing improve cell adhesion and bone ongrowth as compared with machined, SLA, or ANO Ti implants. These findings suggest that the application of Modi-ANO surface treatment could improve the osseointegration of dental implant. 相似文献

A virtual private network (VPN) over Internet has the benefit of being cost-effective and flexible. However, it has difficulties providing sufficient QoS and adequate transmission capacity for high bandwidth services. Given the increasing demand for high bandwidth Internet and the demand for QoS assurances in a VPN over Internet, IP/generalized multi-protocol label switching (GMPLS) based on a control plane combined with a high-bandwidth, dense-wavelength division multiplexing (DWDM) optical network is seen as a very favorable approach for realizing the future optical VPN (OVPN) over IP/GMPLS over DWDM. Within this architecture, providing QoS guaranteed multimedia services with a differentiated QoS guaranteed protocol framework with QoS recovery is one of the key issues to implement. Therefore, we suggest in this paper optical-label switched path (O-LSP) establishment and its QoS maintenance scheme based on differentiated optical QoS-service (DOQoS) classes. They are the key components for this DOQoS framework in assuring end-to-end QoS in an OVPN over IP/GMPLS over DWDM architecture. 相似文献

Smooth shift is one of the key issues in automatic power transmission control systems. However, the torque sensors are too expensive to be used in shift controllers on production vehicles. In order to provide a basic strategy for smooth shifting by using RPM sensors only and in order to accomplish the shift within a designated time, this paper studies detailed characteristics of the smooth shift for clutch-to-clutch shift mechanism. A desired trajectory of slip speed is proposed for smooth acceleration shift defined in this paper. Also the clutch torque needed to achieve this trajectory is derived, and it may be used as a open loop shift control law. 相似文献
