Published: June 2012

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.

Authors: Ho Zih Ping
Published: June 2012

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.

Authors: Dai Yu Jie , Huang Jin Hua , Wang Xue Hui
Published: June 2012

The evolution of growth rate and eigenfunction of kink instability in a cylindrical plasma column with different plasma pressure is studied by a semi-analytical method. The method can transform magnetohydrodynamics (MHD) equations into a second-order ordinary differential equation. Growth rate can be obtained by solving the second-order ordinary differential equation. 2-D radial eigenfunction can be calculated with a fixed growth rate. The significant change of growth rate and eigenfunction indicates inhomogeneous plasma pressure P0 is destructive for kink instability. The advantage of our method is that it can divide problem into two parts and then solve them separately.

Authors: Lin Yi , Liu Bing , Xie Feng , Ren Wen Wei
Published: June 2012

This paper illustrates almost twenty years (1986～2007) of Land use/land cover change (LULCC) in Qingpu-one district of Shanghai. Qingpu District is an area of Upper Huangpu Catchment for fresh water supply with considerable ecological value, but it is also experiencing urban sprawl from development. To reveal the trends underlie LULCC, we propose a novel procedure to quantify different land use/land covers and implement it in the case study. In this procedure, we first collect historical remote-sensing data and co-registered or corrected them to the same spatial resolution and radioactive level. Based upon preliminary interpretation or investigation, land use/land cover types in study area can be included in 5 categories, i.e. Water, Agricultural Land, Urban or Built-up Land, Forest Land, and Barren Land or others. Moreover, data is clipped via boundary of study area for reducing computation load, followed by FPCR-ISODATA classification to divide the data into k groups (k>the number of land types). After postprocessing, e.g., merge the same connoted subgroups and correct misclassified units accompany with validation and verification, the detailed land use/land cover results can be achieved accurately. The quantitative and regression analysis indicate that during the past twenty years the area of agricultural land of Qingpu decreased coupled with urban or built-up area increased linearly. The water area had the minimum change during the decades. Forests had the smallest average proportion (9.6%) of the total area. It occupied so small proportion of land that we can only find points of it in the maps. Barren land can be an indicator for monitoring uncompleted redevelopment or transition of land.

Authors: Ding Xiang Yi , Jia Yang Wen
Published: June 2012

Many observational facts and studies have shown that the climatic conditions in the Hai River Basin, which is the political and cultural centre of China, changed significantly over last half of the 20th century. This study attempts to evaluate the variability of climatic elements such as precipitation and temperature in the basin based on observed meteorological data, and the temporal variations and sudden changes of precipitation and temperature during past 40 years (1961-2000) are analyzed combining moving-average and linear regression with Mann-Kendall method. In addition, the observed climatic changes are attributed to different factors including natural variability and anthropogenic forcing using the fingerprint-based attribution method. The results indicate that: 1) during 1961-2000, the precipitation slightly decreased and the estimated sudden change time was 1965, the temperature significantly increased and the estimated sudden change time was 1964; 2) natural climate variability may be the factors responsible for the observed precipitation changes during the past 40 years in the basin, while anthropogenic forcing may be the main factors responsible for the observed temperature changes during the past 40 years in the basin.

Published: June 2012

Yanshan orogenic belt and its nearby area have thinner earth crust structure, so the asthenosphere of earth mantle upwells and directly bake earthcrust, resulting in Yanshan geothermal anomaly. The type and distribution of thermal spring are controlled by an EW major fault. Thermal springs can be divided into the outcropping type and the hidden type. The outcropping thermal springs mainly spread over orogenic belt in mountain area distributed over northern of Shangyi- Chicheng-Gubeikou-Chengde-Pingyuan fault belt, Hebei. Average temperature of outcropping thermal springs higher than 60°C. Yanshan’s particular earth dynamics and tectonic structure background makes the thermal springs in this area have great prospects for exploitation and utilization

Climatic Trends and Impact on Agriculture in Ningxia
Authors: Chen Hong Xiang , Li Ya Ping
Published: June 2012

This paper characterizes the climate characteristics and observed climate variability in Ningxia, China, using observed daily data from 15 meteorological stations. Climate indices until 2050 and 2100 are projected using the Regional climate impact models PRECIS (Providing Regional Climates for Impacts Studies), emphasizing those which are relevant to agriculture. The results show that the average temperature in Ningxia has increased from 1961-2010 while the mean precipitation has decreased. The frost-free period and accumulated temperature ≥0°C have also increased. Frost-free periods have increased and extended the growing season. PRECIS shows that the annual average temperature, minimum and maximum temperature is projected to increase. Annual precipitation will not change significantly, but the observed dry spells will continue. Increasing temperatures are beneficial for most crop yields but also increase the risk of plant diseases as planting and harvesting times have changed and will change. The regional disparity of water availability, demand and actual use will further be aggravated in future.

Reconstruction and Significance of Palaeopressures of the Jurassic Formation in the Hinterland of the Junggar Basin, NW China
Authors: Li Chun Quan , Chen Hong Han
Published: June 2012

Palaeopressures of the Jurassic formation in the hinterland of the Junggar Basin were reconstructed at different geological time with the method of fluid inclusion thermodynamic modeling. The results indicate that, the generation of overpressure in the east is earlier than that in the west. The overpressure center was first located in the east part of the Changji depression, and then migrated northwestward. The evolution of the formation pressure displays a trend of pressure decrease as a whole, and this trend is composed of three cycles of pressure down and up in block I and IV, but just one in block III and two in block II. Block III is a potential prospective area for hydrocarbon accumulation due to the long-term pressure releasing, and the last cycle which resulted in current formation pressure status in all of the four blocks suggests that the later gas charging had an obvious effect on the pressure accumulation.

The Anthropogenic Factors on Urban Growth: An Empirical Quantification in China
Authors: Cui Xue Zhu , Wang Yao Wu , Chang Yuan
Published: June 2012

The rapid urbanization in China has caused significant urban land use changes and extensive urban growth these years. That has led to a dramatic decrease in arable land and would challenge the national food security. To understand the anthropogenic driving forces of urban growth and find out effective control methods, this study established the Hierarchical Liner Model (HLM) to explore the influence of such factors including society and economy, population, and industry development. On the base of factor analysis and HLM, the decomposition of the affecting factors for urban growth was performed, it visually shows that the social retail goods, public transit passengers, and nonagricultural populations significantly drove the urban growth in China; the tertiary industry development has weak effects on urban growth. By weighting the role of the anthropogenic factors on urban growth, some advices were given at last, and it could provide possible management options for the government to mitigate the excessive urban growth in the near future.
