But, since the day the inflatable tyres were invented, sudden loss of air in a tyre acts as a major problem associated with tyres; and are still being treated to date by professional researchers and giant tyre manufacturers.
Ngadiman, Increasing the tire life span by means of water cooling, Int.

A controlled-release fertilizer (CRF) is one kind of potential method that keeps gaining attention by the agriculture professional in reducing nutrient losses.
To collect the saliva, rinse mouth with water, gargle a little amount of water and spit out into a test tube.
Blend 30 g sweet potato with 30 cm3 of water.
Starch Film Hydrolysis Two percent w/v of starch was mixed in deionised water and immersed into a boiling water bath.
The peak at 1639 cm -1 indicates the existence of water.

Application of an electric engine cooling by water jacket allows to significant excess of its nominal power, known for work in cooling air at temperature of 250C.
Laboratory tests of the new pump design Figure 4 presents the basic characteristics of the pump obtained by laboratory measurements on pure water at 160C.
The velocity field shown in Figure 7 in the water jacket does not demonstrate any significant local turbulence which might generate bigger losses.
In these calculations the flow through the water jacket was simplified to the periodically axisymmetric skipping the inlet to the discharge orifice.

Other literatures also discussed the problem existed in operation, including recharge block [11], corrosion and water quality [12], etc.
Third, reasonably well group arrangement and regional influence, which involves the water level variation, thermal flow variation, cross flow and seepage flow action, porous media properties, etc.
If extracting hot water in high temperature area, or recharging cold water in low temperature area, or both at the same time, cold water will migrate to the hot water area at a certain speed.
The mean temperatures of the outlet water ToM and the inlet water TiM is shown in Fig. 4.
Foundational research work of GWHP system should be increased gradually, especially on theoretical analysis, numerical model building, simulation calculation and professional design.

Damaged sewer pipelines should be repaired to maintain the system efficiency and keep the ground water clean.
The inversion tube is then filled with water (Figure 2 b).
In Figure 2 c, after the tube is inverted through the old pipe to the desired length, the water is circulated through a boiler.
Generally curing is realized with hot water under 150 0C and steam or radiant heating.

The central idea of its representative work: the water pavilion, H2expo in Netherlands, is just based on this, and reveals body in underwater laboratory (experience the feeling of liquid water, but the first is the body feeling surrounded by moving matter).
Beyond the general technological understanding of interactivity, the water pavilion, H2expo, is a permanent structure that does not fit in the classical sense.
So the water pavilion becomes a system between real and virtual water waves, which has stimulation and sensitivity for the appearance of people, and fits for their biological rhythm.
Visitors are like water molecules, sometimes moving as individuals, sometimes in small groups, in excited packs or passive rows, and sometimes in large crowds (Figure6).
Fig.6 Visitors like water molecules in the pavilion Fig.7 Night scene of the water pavilion, H2Oexpo In another research project of “Beachness”, the designer defined the hotel as a field of openness and indeterminacy.

When we start a computational fluid dynamics topic, firstly need to establish a model, namely express the problem with mathematics method by relevant professional knowledge, secondly use computational fluid dynamics software to solve and analyse the problem.

3.1 communication cable line daily maintenance Communication cable is often caused by corrosion, the weather changes, the terrain change, such as lightning natural disaster or man-made damage causes that fault line, at the same time, there are likely into tidal, enter the water and disconnection, grounded.
L wiring equipment to shall be sealed up, outdoor wiring ark, wiring kit is included as standard locking, prohibit to non-professional workers optional touch, wiring material to accurate and clear.
L often examine the wiring cable outer screen grounding are good, the grounding body resistance whether meet the requirements, to open wiring ark, as connecting box, terminal box of pass in and out of the cable to properly handled, fight with the cable into the water, the high voltage power cables across, and dangerous zone should comply with the regulations.

Factor analysis We preliminary draw construction safety influencing factors through analyzing the Three Gorges group's "Key Hazards Process Monitoring Program File", the Three Gorges Project's accident cases statistics in 2005 and 2006 , the production safety accident cases statistics of Xiluodu project from 2005 to 2011 , the accident case statistics of Xiangjiaba dam project in 2005 to 2009 year ,combined with other references and the national formulation each kind of construction standard of security standard. we made pre investigation on the safety and technical director of the department, security management, construction management, supervision engineers, professional engineers, field workers, and other construction and engineering personnel of the security-related, determines four broad heading and 19 kind of factors index finally.
Analysis the main factors affecting quality control of water conservancy project construction.
