Abstract: To explore the association between Insertion/Deletion polymorphism of the angiotensin converting enzyme (ACE) gene and the effects of Living High-Exercise High-Training Low (HiHiLo) on muscle oxygenation (MO), Seventy-one healthy men of Han nationality in northern China underwent HiHiLo training for 4 weeks. Training programme was as follows: exposure in hypoxic environment (14.5%~14.8%O2, 10h/day), three times hypoxic training per week (15.4%O2), and training at sea level. Resting MO, exercising MO and resuming MO were measured by non-invasive near infrared spectroscopy (NIRS) before and after the protocol, and the ACE gene I/D polymorphism was detected by PCR. The findings indicated that exercising MO and resuming MO all increased markedly after training (P< 0.05), but resting MO declined. As to genotypes, no significant differences were in the baseline MO among groups before HiHiLo. Increase in resting MO and exercising MO in II and ID groups were more than those in DD groups, but decline in resuming MO in II and ID groups was less than those in DD groups.The present study suggested that HiHiLo could be helpful for developing individual resting MO and exercising MO, but harmful for resuming MO. Moreover, MO of men carrying II and ID probably were more sensitive to the hypoxic training than those carrying DD.

Abstract: Plackett-Burman design was employed for screening culture conditions for cellulase production by Penicillium decumbens in submerged fermentation. The results showed that wheat bran was the most significant factor influencing Filter Paper Activity (FPA) of the cellulase, followed by cellulose microcrystalline and initial pH, which could be further optimized for improving the cellulase activity. The effects of pH and temperature on FPA assay were investigated, and optimal FPA could be obtained at pH 4.5 and 60 °C. The stabilities of endo-glucanase (EG), exo-glucanase (CBH) and β-glucosidase (BG) were investigated and compared with that of FPA under different pH and temperature. The results indicated that CBH and FPA were more sensitive to pH and temperature than EG and BG and the stability of CBH was very similar to that of FPA under the conditions.

Abstract: The superoxide anion radical and hydroxyl radical scavenging capacities of Cortex Magnoliae Officinals extracts were researched，and the effect of different extracting methods (reflux, ultrasonic and microwave extraction) on the scavenging capacities were studied too. The results indicated that Cortex Magnoliae Officinals extracts had obvious radical-scavenging capacities, and the scavenging capacities were different by different extraction methods. In three kinds of extraction methods, the hydraxyl radical scavenging capacity of Cortex Magnoliae Officinals extract with reflux extraction method was strongest and the superoxide anion radical scavenging capacity of Cortex Magnoliae Officinals extract with ultrasonic extraction method was strongest.

Abstract: A sensitive and selective method was developed for the determination of microcystin-LR (MC-LR) based on proteasomal trypsin-like activity inhibition. Under the optimized conditions, the detection limit for MC-LR was 0.18μg/L, The linearity range was 0.2-2 μg/L，and the average recovery for MC-LR in tap water was 128%. Microcystin-YR (MC-YR) and Microcystin-RR (MC-RR) have no inhibiting effect on the proteasomal trypsin-like activity in the concentration ranged between 0.1-100 nmol/L. This method could be applied for the selective, high-throughput, and rapid determination of MC-LR in waters.

Abstract: Choosing Fadou Town of Xichou County in Yunnan province as an example, and supported by the GIP, this paper uses the analysis result of dynamic monitor on the land use for the renewal of land use, thus forming the current situation chart of the land use after renewal. According to the area changes and types, etc. of the land use, this paper then does a qualitative and quantitative study on the project zone, and based on the dynamic changes of the land use and the conversion between its different types, this paper in the end sets up the matrix of the land use types and provides suggestions and measures to restore the ecological benefit in the rocky desertification area in the light of the practical condition of the project zone.

Abstract: LW3-1-1 located in Baiyun sag of Zhujiang River mouth basin is a potential area for oil and gas submarine Fan based on a detailed study of petrologic and paleontological assemblage characteristics. The fan have developed granular flow, sandy debris flow, low -density turbidity flow and other gravity currents along the slope. Sandy debris flow is the mainly sedimentary type of channel sand bodies of the deepwater fans, and there are also reverse grading, positive grading, parallel bedding and horizontal bedding. In addition, many liquefaction and fluidization structures and biological escape trace in graded bedding as well as abundant burrow pores and bioturbation in horizontal bedding are observed. Based on analysing sedimentary facies, the depositional model of sandy grain flow-debris flow of proximal of marine turbidity fan under the background of initial transgression is proposed for the Zhujiang Formation.

Abstract: A dynamic carbon footprints management system is an important issue in future economics. This research applied geographical information to calculate carbon footprints. It also formulated an orders and trucks assignment problem with capacities of carbon footprints constraints, arrival time constraints and recycling missions constraints to maximize cargoes distribution profits. This study adapted the web based structures for programming, and proposed new approach. After validation, it would increase profits by 46% more than the experience of truck drivers, and profits by 61.5% of that of On Call (individual delivery). If a customer does not attend at a specified place and appointed time, the truck would go back and forward, then consume more gases. Through a web-structure dynamic carbon footprints management system, truck drivers leave ample time to complete their jobs. Future research suggests expanding this research to dynamic routes with consideration of traffic jams.

Abstract: The Zhalantun district of eastern part of Inner Mongolia is located at the northern section of Greater Khingan seismic belt, and it has complicated geological structure, with relatively dynamic moderately strong earthquake in past times and modern times. The seismic activities in this district is selected as the research object; based on the integrity analysis toward seismic sequence in the district, least square method is used to conduct time scanning calculation of b-value, and maximum likelihood method is used to conduct space scanning calculation of b-value. The b-value during the time scanning is the mean b-value of research zone in every scanning window, so its amplitude of variation is not quite great, with range of variation of b-value basically staying within 0.78-1.13, and range of error staying within 0.04-0.065. The space scanning results indicate that the space distribution range of b-value of Zhalantun district basically stays within 0.4-1.6, and the range of error is 0.045-0.085. The low b-value zone is the north central section of Alun River breakage, with b-value basically distributed within 0.5-0.7, which indicates that the earth crust medium of this zone is under the state of high horizontal stress accumulation and it is the dangerous zone where moderately strong earthquake or more occurs in the future.

Abstract: In order to improve the efficiency and cost-saving investigation for sensitive land parcels for road route selecting, this paper demonstrates the methodology of Support Vector Machine (SVM) classification combining with the Normalized Difference Vegetation Index (NDVI) to identify the land parcels using ALOS remote sensing data. One part of the road corridor is taken as the study area in City Group of Changsha, Zhuzhou and Xiangtan, which is regarded as the two society pilot area. The results show that the high effectiveness and applicability of the method in high density vegetation coverage mountainous regions.
