Researches on the relation of a loaded mechanical energy to the damaged banana maturation and its quality evolution has significance to its storage, but there are few researches at present. This paper studied on the effect of the loaded energy on banana to its internal maturation substance evolution and stored quality with time, including the change of maximum impact stress, re-enduring impact energy. The results showed there existed a significant correlation between energy transformation and increment of maturity substance in the damaged banana. Also, there existed a significant association between energy transformation and increment of maturity substance in the damaged banana in its storage time, and appeared a trends that the mechanical energy being transferred into fruit internal energy increased its maturity substance and decreased its stored quality, but individual maturity difference had less effect. Thus, decreasing the energy and the substance transformation in damage area are the important means of extending the physiology life of fruits, which is an urgent problem to be solved in their field of processing and storage at present.

The sustainable development of grain production is a necessary condition for Chinese rapid economic development, which is directly related to people's livelihood and national security. This paper analyzed the frequent occurrence causes of regional drought in China, emphatically enumerated the North-South imbalance of precipitation distribution in time and space, the excessive tillage and grazing and vegetation damage, the hydro-agricultural infrastructure aging and the rapid urbanization diverted for agricultural water resources, which impact the sustainable development of grain production, then proposed some countermeasures coping with frequently regional drought crisis: strengthen the protection of forest vegetation, the scientific planning of planting structure, and the balance regulation of urban industrial water and grain irrigation water, surface water and ground water and of the water allocation between the administrative region, and solve the discharge of sewage purification and desalination technologies, thus establish an integrated balance system of total supply and regional control of grain irrigation water, so as to continuously perfect the durable and stable supply of grain in China.

A Simulation on the Improved Energy Saving Protocol of AODV for Mobile Ad Hoc Network

By Fengying Xu Zhimin Liu Yongchun Xu

DOI: https://doi.org/10.5815/ijeme.2011.02.04, Pub. Date: 29 Aug. 2011

The fixed communication interruption easily occurs in extreme disaster situation, so it needs a robust mobile Ad hoc wireless communication to deliver the rescue information with high quality and efficiency. But the widespread excessive energy consumptions loaded in mobile Ad hoc wireless routing network have become the restriction bottleneck of its application. Based on the routing protocol of AODV, this paper proposed a routing algorithm of AODVSE energy-saving protocol, and studied its effects of the working performance on mobile Ad hoc wireless network. The simulation results showed that the AODVSE protocol could be better to improve the energy-saving performance than AODV and DSR protocols by reducing the routing expiration time and the routing load and extending the network lifetime, in order to help to implement the accurate and immediate rescue.
