Shuli Zhang,Dongyuan Deng
International Education Studies , 2009, DOI: 10.5539/ies.v2n4p25
Abstract: We live in a world, which is becoming a Global Village in which information and communication attract people’s attention more than ever before. Our desire to communicate with strangers and our relationships with them depend on the degree to which we are effective in communicating with them. There are so many factors restricting or improving people’s communication. This essay gives an analysis based on one factor called stereotypes. In intercultural research, the influence of stereotypes on people’s behaviors in communication is a very important issue to take into account. This paper aims to illustrate stereotypes from the aspects of their social and psychological perspectives, great influence on people’s communication, the problems they may cause, and some solutions.

The investigation of surface tension is a very important task for gas hydrate studying. Surfactants can effectively reduce the surface tension, improve the gas storage capability of hydrate and increase the formation rate, shorten the induction time. The objective of this study were to obtain a better understanding of the role of surface tension on hydrate formation and build gas hydrate models involve surfactant. In this study it was highlighted that the surface tension of Intechem-01 + SDS composite surfactants in natural gas hydrate promotion system and the change rules at different temperatures, concentration and proportion. According to the results of experiment, the surface tension of composite surfactants decreased with the increase of Intechem-01. The best cooperating effect was observed in proportion (Intechem-01 content) of 0.6 - 0.7, where the surface tension was the lowest. In this proportion range, the composite surfactants showed the same effect to pure fluorine carbon surfactant. The study shown the surface tension of composite surfactants decreased with the rise of temperature, and they were in a linear relationship within a certain range. Surface tension of composite surfactants decreased with the increase of surfactant concentration, however, it was no longer decreased above critical micelle concentration (CMC). The fitting equation of surface tension with various factors has been obtained.

Shu Zhang, Ying Li, Guanjie Xu, Shuli Li, Yao Lu, Ozan Topracki, Xiangwu Zhang
Soft Nanoscience Letters (SNL) , 2012, DOI: 10.4236/snl.2012.23010
Abstract: Li2MnSiO4 has an extremely high theoretical capacity of 332 mAh?g?1. However, only around half of this capacity has been realized in practice and the capacity retention during cycling is also low. In this study, Li2MnSiO4/carbon composite nanofibers were prepared by a combination of electrospinning and heat treatment. The one-dimensional continuous carbon nanofiber matrix serves as long-distance conductive pathways for both electrons and ions. The composite nanofiber structure avoids the aggregation of Li2MnSiO4 particles, which in turn enhances the electrode conductivity and promotes the reaction kinetics. The resultant Li2MnSiO4/carbon composite nanofibers were used as the cathode material for Li-ion batteries, and they delivered high charge and discharge capacities of 218 and 185 mAh?g?1, respectively, at the second cycle. In addition, the capacity retention of Li2MnSiO4 at the first 20th cycles increased from 37% to 54% in composite nanofibers.

Journal of Agricultural Science , 2013, DOI: 10.5539/jas.v5n2p64
Abstract: Strawberry is an economically valuable crop all over the word. Proanthocyanidin is one polyphenol compound rich in strawberry fruits owned significant antioxidant capacity and claimed beneficial health effects. Anthocyanidin reductase (ANR) and leucoanthocyanidin reductase (LAR) are both key enzymes of the branch of proanthocyanidins biosynthesis pathway, which are responsible for the production of (-)-epicatechin and (+)-catechin, respectively. In this study, the expression levels of the Fa-ANR and Fa-LAR gene and the total PAs concentration at seven developmental stages of the strawberry fruit were investigated. The results showed that the PAs contents gradually reduced along with the fruit maturation; while the expression patterns of Fa-ANR and Fa-LAR were consistent with the PAs. These results indicated that LAR and ANR were both key enzymes in proanthocyanidin biosynthesis.

Abstract: Objective: The aim of our study was to analyze the character of cause of death in Inner Mongolia of China from 2008 to 2014. Methods: We collected data from monitoring points of the Death Registry System (DRS) in Inner Mongolia. We calculated the mortality rates by gender, year and age-specific. We calculated the proportion, the mortality rate and potential years of life lost (PYLL) of various system deaths. Results: During the period 2008-2014, the average crude mortality rate of all cause of death was 539.33/105. The mortality rate increased semilogarithm linearly with age. The top four system deaths were circulatory system, neoplasm, respiratory system and injury. In 2014, the mortality rates of circulatory system were increased and the mortality rates of certain infectious and parasitic diseases, neoplasms, respiratory system, genitourinary system and injury were decreased compared to those in 2008. Conclusion: Through analysis the indicators of proportion, the mortality rate and PYLL indicated that health status of a population in Inner Mongolia was at a better level.

Perspectives of Innovations, Economics and Business , 2011,
Abstract: During the last time in the development of the financial reporting and frauds there have emerged several problems related to the quality of several indicators on the financial statements and especially the quality of the earnings indicator. According to the literature on the financial reporting it results that companies have the possibility to smooth earnings or manage earnings as a tool to avoid reporting a loss. While the economic entities are using the national and international accounting standards, the working practice of accountants/auditors shows episodes of the management of the earnings. One of the conclusions of this paper is that there is not enough information among accounting professionals regarding the practices of the earnings management. One of the recommendations is to include issues of fair and ethical reporting in the modules of the faculty of economics especially on the master level.Based on the many studies of this issue in other countries, this paper will show if this phenomenon is known in Albania and furthermore how important it is for the quality of the financial reporting in Albania. In order to achieve this objective it has been done a review of related studies. Because of the new legislation on the financial reporting being implemented in our country the recommendations of this paper may be valuable to the enforcement of the accounting standards mechanisms.

Abstract: Background Mowing is a widely adopted management practice for the semiarid steppe in China and affects CH4 exchange. However, the magnitude and the underlying mechanisms for CH4 uptake in response to mowing remain uncertain. Methodology/Principal Findings In two consecutive growing seasons, we measured the effect of mowing on CH4 uptake in a steppe community. Vegetation was mowed to 2 cm (M2), 5 cm (M5), 10 cm (M10), 15 cm (M15) above soil surface, respectively, and control was set as non-mowing (NM). Compared with control, CH4 uptake was substantially enhanced at almost all the mowing treatments except for M15 plots of 2009. CH4 uptake was significantly correlated with soil microbial biomass carbon, microbial biomass nitrogen, and soil moisture. Mowing affects CH4 uptake primarily through its effect on some biotic factors, such as net primary productivity, soil microbial C\N supply and soil microbial activities, while soil temperature and moisture were less important. Conclusions/Significance This study found that mowing affects the fluxes of CH4 in the semiarid temperate steppe of north China.

Abstract: Soil is one of the most important carbon (C) and nitrogen (N) pools and plays a crucial role in ecosystem C and N cycling. Climate change profoundly affects soil C and N storage via changing C and N inputs and outputs. However, the influences of climate warming and changing precipitation regime on labile and recalcitrant fractions of soil organic C and N remain unclear. Here, we investigated soil labile and recalcitrant C and N under 6 years' treatments of experimental warming and increased precipitation in a temperate steppe in Northern China. We measured soil light fraction C (LFC) and N (LFN), microbial biomass C (MBC) and N (MBN), dissolved organic C (DOC) and heavy fraction C (HFC) and N (HFN). The results showed that increased precipitation significantly stimulated soil LFC and LFN by 16.1% and 18.5%, respectively, and increased LFC:HFC ratio and LFN:HFN ratio, suggesting that increased precipitation transferred more soil organic carbon into the quick-decayed carbon pool. Experimental warming reduced soil labile C (LFC, MBC, and DOC). In contrast, soil heavy fraction C and N, and total C and N were not significantly impacted by increased precipitation or warming. Soil labile C significantly correlated with gross ecosystem productivity, ecosystem respiration and soil respiration, but not with soil moisture and temperature, suggesting that biotic processes rather than abiotic factors determine variations in soil labile C. Our results indicate that certain soil carbon fraction is sensitive to climate change in the temperate steppe, which may in turn impact ecosystem carbon fluxes in response and feedback to climate change.
