Tis is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. A temperature index model with delay and stochastic perturbation is constructed in this paper. It explores the infuence of parameters and stochastic factors on the stability and complexity of the model. Based on historical temperature data of four cities of Anhui Province in China, the temperature periodic variation trends of approximately sinusoidal curves of four cities are given, respectively. In addition, we analyze the existence conditions of the local stability of the temperature index model without stochastic term and estimate its parameters by using the same historical data of the four cities, respectively. Te numerical simulation results of the four cities are basically consistent with the descriptions of their historical temperature data, which proves that the temperature index model constructed has good ftting degree. It also shows that unreasonable delay parameter can make the model lose stability and improve the complexity. Stochastic factors do not usually change the trend in temperature, but they can cause high frequency fuctuations in the process of temperature evolution. -

Analysis of Historic Rainfall Characteristics for Robust Wheat Cropping in North Anhui
Analysis of historic rainfall characteristics for robust wheat cropping in North Anhui Hui Su, Yibo Wu, Yulei Zhu, Youhong Song Anhui Agricultural University, School of Agronomy, Hefei, 233036. Corresponding email: [email protected] Abstract Northern part of Anhui is one of major wheat producing areas in China. The total amount of rainfall is sufficient for wheat season; however, it is unevenly distributed at the different growth stages, resulting in risk of yield losses. In order to optimise the cultivation in North Anhui, it is essential to characterise the rainfall pattern for wheat growth particularly in the critical period (i.e. the months of sowing and harvesting). By analysing the rainfall data from 1955 to 2017, this study characterised the rainfall pattern from six sites representing different regions of North Anhui. The frequency of continuous rainfall days during sowing and harvesting periods were quantified based on 63 years rainfall distribution. The characterisation of rainfall in six representative sites in North Anhui were able to be used to guide wheat sowing and harvesting, which could help farmers to make decisions and avoid likelihood of cropping risks. Key Words Winter wheat, rainfall pattern, sustainable cropping, China Introduction Huang-Huai-Hai plain is a major wheat production area in China (Yang, 2018). The northern part of Anhui province belongs to south Huang-Huai-Hai plain. The wheat sowing time normally varies 1 week before or after October 15 and harvesting is tightly closing to May 31 in the following year. The climate characteristics particularly rainfall distribution over the season are complicated in North Anhui as it is in the transitional zone between the North and South China. -

In order to quantitatively assess the capacity of regional agriculture system to reduce losses from drought disasters under complex conditions and to identify vulnerability indexes, an assessment and diagnosis model for RADR was established. Firstly, this model used the improved fuzzy analytic hierarchy process to determine the index weights, then proposed an assessment method based on connection number and an improved connection entropy. Furthermore, the set pair potential based on subtraction was used to diagnose the vulnerability indexes. In addition, a practical application had been carried out in the region of the Huaibei Plain in Anhui Province. The evaluation results showed that the RADR in this area from 2005 to 2014 as a whole was in a relatively weak situation. However, the average grade values had decreased from 3.144 to 2.790 during these 10 years and the RADR had an enhanced tendency. -

Nutraceuticals and Nutrition Supplements July 18-19, 2016 Bangkok, Thailand
Zhao-Jun Wei, J Nutr Food Sci 2016, 6:4 (Suppl) conferenceseries.com http://dx.doi.org/10.4172/2155-9600.C1.023 2nd International Conference on Nutraceuticals and Nutrition Supplements July 18-19, 2016 Bangkok, Thailand The nutraceutical properties of polysaccharides sequential extracted from peony seed dreg Zhao-Jun Wei Hefei University of Technology, China eony seed dreg, a byproduct of oil processing, is rich in many nutrients. However, this is always used as animal fodder and fertilizer. PMy laboratory has explored the possible use of nutrient-rich peony seed dreg as a functional food. To this end, Peony seed dreg polysaccharides (PSDP) were sequentially extracted using hot buffer (HBSS), chelating agent (CHSS) and dilute alkaline (DASS) followed by concentrated alkaline (CASS). The nutraceutical properties of the various polysaccharides fractions were investigated. The four PSDPs possessed simple composition and showed the characteristic absorptions for polysaccharides at 3600-3200 cm-1 and 3000-2800 cm-1. The functional group of four PSDPs displayed some slight differences. The results of melting point and enthalpy of four samples confirmed a good thermal stability. The emulsifying activity and emulsifying stability of four PSDPs exhibited dose- dependent response, HBSS with the highest emulsifying activity and CHSS with the longest emulsifying stability. Comparison among the antioxidant activities of four PSDPs, CASS showed highest abilities in the DPPH radical scavenging activity, reducing power and ABTS radical scavenging activity, HBSS exhibited the highest hydroxyl radical scavenging activity and CHSS displayed the higher chelating ability on ferrous ions than others. At a liquid-solid ratio less than 2.5% w/w in aqueous solution, the polysaccharides extracted from peony seed presented non-Newtonian shear thinning behavior and could be well described by the Cross model.
