The teacher is a friendly jet strict example figure, is constantly developing his / her professional skills [6].
More recent, Michael Pawlyn is designing structures in the middle of the African deserts to make them green again by studying how insects collect water in one of the driest places on earth [25].
A few months ago I came across the site ‘Play the city’ [31] were people, specialized in all kind of fields, professionals, are invited to play on the Internet in order to solve some urban questions that should have been solved years ago.

As highly porous material it can absorb water and release it slowly into the soil.
Gas formation can be achieved via expulsion of hydration water from clay minerals or via decomposition or reduction of inorganic salts and oxides.
Granules were shaped by adding a controlled amount of water in order to achieve the consistency needed for shaping.

., (Tianjin, China). 2.2 Fabrication of microPCMs/epoxy composites The encapsulation was carried out in a 500 ml three-neck round-bottomed flask. 3.0 g SMA and 0.8 g NaOH were dissolved in 100 ml water (50 °C).
Then dropped the emulsion in the bottle dipped in steady temperature flume and stirred at a speed of 1500 r·min-1, and dropped 25 g mixture of prepolymer (12.8 g) and deionized water at a rate of 0.25 g·min-1.
The resultant microcapsules were filtered and washed with water and dried in a vacuum oven.
The method to evaluate the encapsulated ratio (E) is by Eq.1, (1) Where is the calculated heat fusion of microPCMs by DSC, the latent heat of fusion of PCM, is the total weight of PCM in emulsion. is the value of microPC- Ms, calculated through the integral of the curves area by software Origin 8.0 Professional. 2.5 TGA measurement Ten micrograms of the dried microPCMs sample was tested with a heating rate of 5 °C·min-1 and nitrogen (N2) as the purging and protective gas.

Green construction refers to the construction process that in the precondition of the basic requirements of quality and safety and so on, through scientific management and technological progress to maximize the conservation of resources and reduce the negative environmental impact of construction activities and achieve energy-saving, land, water, materials and environmental protection.But in real life, in order to achieve the construction time not harass the people and damage the environment is not possible if not very good planning.
In the high-rise reinforced concrete shear wall and frame structure construction, the roof template construction of high-rise structure engineering still use bamboo glue formwork or multilayer board with primary and secondary wood keel with the bowl frame forming roof formwork support system to meet the water demand with the further construction mechanization degree and fine management.the normal construction generally need three layer turnover materials to meet the water demand(that is bamboo glue formwork, bowl rack, secondary keel wood)especially timber, because the actual need of building construction (size does not fit) part of overlap coefficient or wood to be truncated which will increase the amount of loss and the board can utilization rate is very low, so resulting in a large waste of wood.
In August 2010, the project applied to the Hawthorn home 1 #, 2 #, 3 #, 4 # Building Project, and was a complete success, the construction is simple and does not require professional operators, safety, construction progress is quickly,make the construction ahead of schedule to complete about 30 days.

Deionised water was used throughout the experiments. 2.2 Methods 2.2.1 Synthesis The amine functionalized CoFe2O4 and NiFe2O4 nanoparticles were prepared by thermal decomposition method as reported elsewhere [23].
This procedure, as compared with our earlier techniques of synthesis, is found to yield reasonably stable dispersions in water. 2.2.2 Characterization X-ray diffraction patterns of the dried powder samples were recorded on a Rigaku Ultima IV diffractometer equipped with Cu/Kα radiation at a scanning rate of 2o/min in the 2θ range of 20 to 80 degrees (λ = 0.15405nm) (40 kV, 40mA).
Blood samples were collected from healthy donors through venepuncture by a qualified professional, using disposable materials throughout the procedure.
UV-Visible spectra of the CoFe2O4 and NiFe2O4 nanoparticles dispersed in water are compared in Fig (4a & b).

It makes real-time and automatic polling of the dispatching automated systems and key network nodes, and timely detects the network anomalies according to the response. [5] It monitors the operating conditions of the links between the important network devices, network management system in the network and the professional network management and network elements, and if it finds the faults, it will display the alarm information at the system alarm window and store it in the system log.
The water leakage detection function The water leakage detection function is to detect in real time the water leakage of the pipes and joints of the air conditioning system in the automated computer room and the power grid control center computer room, and make automatic alarm.

Taking distilled water as the immersion liquid, the following equation was used to evaluate the density measurement: d = w1w1-w2 ×d1 (1) where w1 is the weight of sample in air, w2 is the weight of sample in distilled water, and d1 is the density of distilled water[20].

The flood accident includes two kinds of accidents: flooding accident, collapse of water and plup accident.
Statistics of 22 massive colliery mine blasting accidents in Guizhou province show that the number of blasting member without license and non-professional staff reaches 86.4%.
Analysis of unsafe acts of blasters Among the 133 massive colliery accidents of coal mine blasting, 72 accidents were caused by blasters , after analysis these accidents(refer with: Table 1), finding the frequency of all the unsafe acts of blasters from high to low is: open fuse(electric)blasting, ignore omen, not using qualified taphole mix(coal cinder, loess), not using qualified explosive, burden deficiency, blasting in a condition of not understanding coal face(hydrogeology conditions), sealing clay deficiency, not using qualified blasthole(dip angle, spacing), blasting busbar bare drain, not using qualified water stemming, not sealing, Overcharge, reverse blasting(under the state of excess of gas concentration), not using qualified exploder, unfavorable blocking of boreholes, using the exploder in unsafe conditions, improperly using exploder, and improperly connecting blasting bus.
