A professional soccer player experiences a median of 800 heading occasions every season excluding the headings that take place during training sessions [3].
Apart from the amateurs, a group of 84 professional soccer players were evaluated through neuropsychological tests to determine the relation between the number of headings in a season and the number of soccer-related concussions with the cognitive function [7].
They have measured the movement of water molecules along nerve fibres called axons.

The spraying person said before fruit trees’ germination, they will use the LSSS ( LSSS ,an agricultural fungicide, is composed of lime, sulfur and water and decocted, it’s highly effective and durable, low residue, and can be sprayed not more than 4 times a year).
During the Olympic Games in 2008, all fruits are required to pass the professionals’ detection of pesticide residues, and can be used when they are qualified.
As fro fruit cultivation base, whose supply object is some group or bulk purchase, so it is beneficial to ensure the quality of products for the long-term and effective cooperation, but for the planting base, selling fruit has relatively high additional value, it can win a relatively high profit space, thus we recommend planting base set up his own testing laboratories or entrust three party institutions for fruit quality inspection; and for the scattered farmers, they must firstly strengthen pesticide knowledge training and guidance, but they need help from the government and the local governments and related departments .In Beijing , more than 60% fruits are produced by scattered farmers, so this is a group can not be ignored, how to improve professional quality of them is the guarantee of safety supply of fruit in Beijing.

It is the whole picture of urban entity color factors, which includes, in a narrow scene, natural environment color (such as mountain, soil, water system and vegetation), urban artificial building color (such as building, road and landscape sketch) and flow color (such as celebrating activities, costumes and automobiles).
There is conceptual confusion even for professionals on the cognition of color planning, for example, they can not tell the difference between color planning and color design, and difference between architectural color and urban tone.
People will have different perception for the color under different weather conditions, cultures, and professional backgrounds and with different moods.

For the protection of agricultural water security and agricultural sustainable development of circular economy, the city of Dalian during the second five to improve water use efficiency, will take the following measures to develop water-saving agriculture: (1) Water township and village enterprises.
Qualified enterprises to actively use water instead of fresh water for cooling water, industrial water recycling rate indirect cooling of 85%.
Implementation of the Farmland Water Improvement Project 1090, the new Small Water 1612 (Office), repair embankments 420, the new water-saving irrigation area of ​​13 mu, the new water-saving capacity of more than 2100 tons.Continue to do a good job supporting the construction of large-scale irrigation water, continue to spread irrigation, drip irrigation and other water-saving technologies and facilities.
To promote water saving in rice seedlings and water-saving farming, water-saving irrigation area of ​​more than 20,000 hectares.By2015, water-saving irrigation area of ​​Dalian City, 36.77 million mu, water-saving irrigation area of ​​the effective irrigation area ratio to 66%, the effective utilization rate of agricultural irrigation water to 55% 20% saving rate, a preliminary to a water-saving requirements of the development of ecological agriculture.朗读 显示对应的拉丁字符的拼音 字典 (3) Promotion of life saving appliances and desalination technology.
In addition to these water-saving measures, the city should develop more stringent water management system, a fixed water supply, improve water reward and punishment system to waste.

For the destruction of classified storage media[3], by professional equipment to its cutting crushed, crushed residue particles required to meet national security standard BMB21-2007 the relevant provisions.
With the increase of the number of overwrite, it will be difficult for the original data completely recovery even using the professional data recovery software.
Data delete method can't completely clear data, use some special software recovery tools can make the data reduction; Strong degaussing method, burning high temperature destroyed method, physical damage method, chemical corrosion damage method these several ways need professional destroyed equipment or chemical reagent, and require manual intervention to remove storage media data destruction from buoys, it is unrealistic for marine environmental monitoring buoy data storage module.
If the positioning display buoy location is still in our territorial waters under the jurisdiction of the scope of the tube, just at the right time make buoy homing; If can’t make buoy timely homing in the short time or buoy has flown out of the sea areas, and worry about the buoy stored marine environmental elements data is illegal agencies to obtain, can make data destruct through the data overwrite way.

With the development of society and economy, China's investment in construction projects is increasing, which requires the construction and management staff to improve their professional level, to develop a more scientific construction plan to ensure construction quality, and ultimately to the construction goal.
For example, when the sinkage is large and there is a relatively shallow groundwater depth, surface subsidence will cause ground water, which will not only affect the normal use of the building, but also decrease the foundation soil strength since long been immersed in water.
The source influencing uneven settlement of surrounding buildings is the whole construction process of foundation pit engineering, including the construction of the building envelope, to reduce the water table before excavation pit, excavation into the design process.
Deformations of the soil and changes of the water table will affect the stability of the building structure.

Based on Analytic Hierarchy Process in the Study of Cave Construction Yin Zhang1, Hui Yang2 Xi’an University of Architecture & Technology, Xi’an, 710055, China Key words :Cave ; Analytic Hierarchy Process ; Ladder Level Structure Model Abstract: This article mainly study on AHP application in cave dwelling construction system, based on the combination with professional experience and the investigation of the folk, put forward the influence factors of building in caves, By establishing the hierarchical structure model ladder to explain the interaction of the various factors relationship,And then calculate and recognize the key factors in influencing of the cave-building, in the hope of improving the construction quality of a cave reference function.
Because of soil has vertical joints, when water penetrates into the soil, its vertical penetration is 50 times as horizontal penetration. so it is the most important for caves waterproof
Mice and worms usually hole in the soil, it can form the pores which let water inject into the cave.
If the cave has used for a long time, the top of cave will collapse due to water seepage.
