Dynamic Analysis of Catapult Availability Based on CBM
Xia Guo-Qing,Luan Tian-Tian,Sun Ming-Xiao,Liu Yan-Wen 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.10
The repair of catapult is a complicated engineering. In this paper, the method of Condition Based Maintenance is applied into the repair system based on the catapult maintenance of system analysis. In view of the application of Condition Based Maintenance in the modern aviation equipment, the catapult availability is the final goal. The structure of catapult maintenance system is analyzed. The structure model of system dynamic feedback is established by using system dynamics method. Simulation is based on the "Nimitz" actual data of the Surge operation in 1997. The results prove the effectiveness and rationality of the proposed method. Through the analysis of the simulation evaluation results, the method applying Condition Based Maintenance into catapult repair system can improve catapult availability.

In vitro and in vivo Evaluation of the Antitumor Efficiency of Resveratrol Against Lung Cancer
Yin, Hai-Tao,Tian, Qing-Zhong,Guan, Luan,Zhou, Yun,Huang, Xin-En,Zhang, Hui Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.3
Lung cancer remains a deadly disease with unsatisfactory overall survival. Resveratrol (Res) has the potential to inhibit growth of several types of cancer such as prostate and colorectal examples. In the current study, we evaluated in vitro and in vivo anticancer efficiency of Res in a xenograft model with A549 cells. Cell inhibition effects of Res were measured by MTT assay. Apoptotis of A549 cells was assessed with reference to caspase-3 activity and growth curves of tumor volume and bodyweight of the mice were measured every two days. In vitro cytotoxicity evaluation indicated Res to exert dose-dependent cell inhibition effects against A549 cells with activation of caspase-3. In vivo evaluation showed Res to effectively inhibit the growth of lung cancer in a dose-dependent manner in nude mice. Therefore, we believe that Res might be a promising phytomedicine for cancer therapy and further efforts are needed to explore this potential therapeutic strategy.

Identification and characterization of CONSTANS-like genes from Curcuma alismatifolia
Yuan-Yuan Li,Xiao-Huang Chen,Hui-Wen Yu,Qi-Lin Tian,Luan-Mei Lu 한국원예학회 2021 Horticulture, Environment, and Biotechnology Vol.62 No.2
The CONSTANS ( CO ) and CONSTANS - like ( COL ) genes have an important role in the regulation of fl owering in photoperiod-sensitive plants. However, information on the molecular characterization of COL genes in Curcuma alismatifoliais very limited. The objective of this study was to identify and evaluate 8 COL homologs ( CaCOLs ) in the C. alismatifoliatranscriptome. Their structures, phylogenetic relationships and expressing patterns under short-day (SD) and long-day (LD)contexts were investigated. Our results showed that CaCOLs were classifi ed into three groups: CaCOL3 and CaCOL6 in groupI were the most CO - like genes; CaCOL7 and CaCOL8 in group II contains only one B-box; CaCOL1 to 2 and CaCOL4 to 5formed the group III. Phylogenetic analysis of the CaCOLs in Arabidopsis, Rice, Barley, Malaccensis and C. alismatifoliademonstrated that both the B-box and CCT domains were conserved in dicot and monocot plants, but diff erent groups ofCOL genes evolved independently. Diff erent patterns of mRNA accumulation in C. alismatifolia leaves in response to SDand LD treatments were observed. CaCOL1 , CaCOL2 , CaCOL4 and CaCOL7 showed signifi cantly higher expressions inLD treatment than that of SD, indicating that they were potential fl owering inducers, and are candidate genes for research infl owering regulation and circadian controlling in C. alismatifolia plants. Altogether, our study facilitates successful regulationof fl owering in Curcuma species and provides insights for future molecular breeding programs.
