超强筋小麦粉面包烘焙技术研究

为了烘焙出能充分表现超强筋小麦济麦229面粉品质特性的优良面包,设置了4种醒发时间处理、5种酵母和糖用量处理、4种配粉处理,对超强筋小麦面粉的面包品质进行了评价分析。结果表明,在4个醒发时间处理中,当面团醒发时间为30min和面包胚醒发时间为50min时,烘焙的面包品质最好。在5种酵母和糖用量的处理中,利用吐司面包程序时,干酵母和糖的用量分别为6g和24g时烘焙的面包品质最好；利用法式面包程序时,干酵母和糖的用量分别为3g和18g时烘焙的面包品质最好。在4个配粉处理中,200g超强筋小麦济麦229面粉中添加100g普通小麦济麦22面粉的混粉烘焙得到的面包品质最好。因此,适当调整超强筋小麦粉面包的面团、面包胚醒发时间及物料配比,可以烘焙出品质优良的面包。     

财政性科技经费监管体系探析

我国初步建立了财政性科技经费监管体系,但是在监督主体、监督制度等方面还存在缺陷,科技经费监督出现诸多问题。建立要加强宏观层面的统筹规划,建立由政府、承担单位和外部主体上下联动、横向联合的立体监督体系。

General mechanisms of drought response and their application in drought resistance improvement in plants

Plants often encounter unfavorable environmental conditions because of their sessile lifestyle. These adverse factors greatly affect the geographic distribution of plants, as well as their growth and productivity. Drought stress is one of the premier limitations to global agricultural production due to the complexity of the water-limiting environment and changing climate. Plants have evolved a series of mechanisms at the morphological, physiological, biochemical, cellular, and molecular levels to overcome water deficit or drought stress conditions. The drought resistance of plants can be divided into four basic types-drought avoidance, drought tolerance, drought escape, and drought recovery. Various drought-related traits, including root traits, leaf traits, osmotic adjustment capabilities, water potential, ABA content, and stability of the cell membrane, have been used as indicators to evaluate the drought resistance of plants. In the last decade, scientists have investigated the genetic and molecular mechanisms of drought resistance to enhance the drought resistance of various crops, and significant progress has been made with regard to drought avoidance and drought tolerance. With increasing knowledge to comprehensively decipher the complicated mechanisms of drought resistance in model plants, it still remains an enormous challenge to develop water-saving and drought-resistant crops to cope with the water shortage and increasing demand for food production in the future.

An Economic Model-Based Matching Approach Between Buyers and Sellers Through a Broker in an Open E-Marketplace

A broker in an open e-marketplace enables buyers and sellers to do business with each other. Although a broker plays an important role in e-marketplaces, theory and guidelines for matching between buyers and sellers in multi-attribute exchanges are limited. Therefore, a challenge for a broker’s responsibility is how to maximize a buyer’s total satisfaction degree as its goals under the consideration of trade-off between a buyer’s buying quantity and price paid to a seller, and other attributes. To solve this challenge, this paper proposes an economic model-based matching approach between a buyer’s requirements and a seller’s offers. The major contributions of this paper are that (i) a broker can model a seller’s price policy as per a buyer’s buying quantity through communication between a broker and a seller; (ii) due to each buyer’s different quantity demand, a broker models a buyer’s satisfaction degree as per a buyer’s buying quantity based on communication between a broker and a buyer; and (iii) to carry out a broker’s matching processes, an objective function and a set of constraints are generated to help a broker to maximize a buyer’s total satisfaction degree. Experimental results demonstrate the good performance of the proposed approach.
