The dry weight (i.e. weight before soaking in water) of the specimens for the water absorption test was recorded as the initial weight and afterwards horizontally arranged in a container with distilled cold water at 20oC temperature.
The boards were soaked in water for 1 hour and 24 hours as that of the water absorption test.
Fig. 5 Water Absorption and Thickness Swelling Values of Ceiling Boards The mean values obtained from WA in 1 hour of water immersion ranged from 10.29% to 26.12% and for 24 hours of water immersion ranged from 24.84% to 29.32%.
The mean values obtained from TS in 1 hour of water immersion ranged from 0.55% to 5.80% and for 24 hours of water immersion ranged from 2.79% to 7.21%.

The cargo throughput of coastal ports increased by 385 million tons from 2008 to 2009, significantly higher than the additional handling capacity of 339 million tons. 2) At present Chinese terminals and waterways of major coastal ports haven’t met the requirements of the ship large and professional development in the structure; despite the lack of coastal port shoreline resources, the utilization is not high; and the interregional investment in the coastal ports gets uneven.
Grasping various coordinated development in the principle of "unified planning, rational distribution, joint development, and improved matching", exploit and protect coastal resources rationally; give priority to ensure the needs of deep-water piers and coastlines, and arrange the units with not high requirements of the water depth conditions to the shallow water; Meanwhile, the deep development of industrial and warehousing facilities and the use of public specialized ports should be encouraged.
Nowadays, the coastal raw material industrial bases, which rely on deep-water ports and overseas resources, are much seldom in China.
The “Waterway Law”, “‎Water Law” and some other laws should be improved further.

The control signal processed in the control layer is a binary chemical information, here the binary concentration of water (cH20 = 0: water is not applied; cH20 = 1 : water is applied).
The closings valves are fabricated by the photolithographic polymerization of 2 g of sodium acrylate, 0.04 g of the crosslinking agent (N,N'-methylenebisacrylamide) BIS, and 0.04 g of the photoinitiator (2-hydroxy-4'-(2- hydroxyethoxy)-2-methylpropiophenone) (all chemicals are obtained from Aldrich) dissolved in 14 ml distilled water (in the following this solution is referred to as c0).
The array is photopolymerized on a 20 µm foil (Professional Flip-Frame Transparency Protectors, 3M) pretreated with 2,2'-azino-bis(3-ethylbenzothiazoline-6- sulphonic acid) (ABTS) dissolved in Bicyclohexyl (both obtained from Sigma-Aldrich) to enhance the adhesion of the actuators.
For facility of inspection, in 3(b) and 3(d) control and data layer are shown separately.To trigger a measuring cycle in which all fluidic operations necessary for sampling, sample preparation and conduction of the reaction are carried out, the inlet of control layer only has to be provided with a control liquid, in the simplest case with water.

Environmental Protection Agency, Green (environmental) wastes can be defined as “excessive use of resources utilized or released in air, water or land that harms the human health or environment” [13].
If the process uses hazardous materials and/or water in processing or cleaning the product, additional amounts of these resources are required [17]
Machines that are waiting may still consume energy, consume water and generate hazardous and greenhouse emissions [17]
• Excess processing causes wastes energy, generates emissions, water consumption or hazardous materials as well.

Normally, it should efficiently use energy, water, land, and materials, as well as reduce waste and pollution, provide high quality environmental[5][4].
The concerns like energy and water efficiency in design phase have discussed above, here I will focus on construction and operation phase.
Carry out risk assessment survey of domestic hot water systems 8.
Also, many natural disasters have recently happened, such as the “5.12” Wenchuan earthquake in 2008, and the Beijing “7.21” storm water flooding 2012, as well as Yuyao storm water flooding recently.
In addition to this point, the planner has to face the new field to educate or training other people who might be resident, social worker even some planners who are not professional in GREEN, which will result in the unforeseen work.

In addition, the increased percentage of MRSG residue increased the water absorption of the mix.
The concrete cube specimens were removed from the molds and cured in water at a constant temperature.
Apart from cement, MRSG has a robust tendency to absorb water.
Due to lack of water, a shortcoming of complete hydration reaction has occurred.
