Professionals have examined the PL of different materials and developed many macro and microscopic luminescence based devices.
The sensitivity and selectivity of PL in many micro systems facilitates the professionals to estimate amino acids, proteins and nucleic acid in medico-legal works.
This adaptation allows the fish to see red-pigmented prey, which are normally invisible in the deep ocean environment where red light has been filtered out by the water column [9, 24].
The most common lyoluminescent effect is seen when solid samples which have been heavily irradiated by ionizing radiation are dissolved in water.

The captured data as well as the consequent evaluation were carried out in GOM Inspect Professional v8.
The part was merely rinsed under running water.
Fig. 10 Specimens after washing with running water.
Its structure remained unchanged under the water and the part had to be cleaned mechanically using ethanol.
In these two cases, the running water cleaned the part perfectly (without any necessary mechanical action).

Diagram of coordinated and feed water control system of super-critical power unit is shown in Fig.4.
The main controller of water supply control circuit can be set with feed water flow to form feed water flow instruction, which is compared with real-measured water flow to form a deviation, after which being operated by PID regulating law the controller output can regulate pump’s speed.
The circuit of forming feed water flow instruction has such features as: according the mathematical expectation seeked out by using probability statistics method from the long-term running actual correspondence relationship between the fuel volume and water supply flow to regulate function f1(x) representing the relationship between fuel volume (by BTU compensation ) and water supply flow under different loads; to seek out mathematical expectation f2(x) of separator export steam temperature under different loads(steam flow); introducing the state feedback control based on IFO-KDx to forecast the changing trend of water supply flow; to modify set value of feed water flow by PID regulation law; to introduce dynamic link 1 in fuel and feed water flow loop to compensate the dynamic deviation of fuel quantity and feed water flow; the use of dynamic link 2 and f3(x) is to limit the amount of fuel increasing (or decreasing) when the separator outlet steam temperature rising (or falling) more quickly
The first generator unit of yaomeng power plant in henan province is a subcritical 300 MW unit with double-furnace once-through boiler, the water wall as a whole exerts forced circulation relied on the boiler-water circulation pump before the minimum load point, and after that, the steam-water system runs with separator in pure direct mode.

A disadvantage of rammed earth is its fragility to water damage.
One special ingredient was sticky rice: first it was ground, secondly poured in cold water, then poured in a lot of boiling water (sugar could be added at this time), finally the conglutinate liquid was added and merged to the mixture of earth.[ There are different ways in making the mixture of earth in different regions of China, I only mentioned the general process in preparing the rammed earth.
Making blue bricks required baking at 1000°C baking and spraying water in addition from the top of the kiln.
Making red bricks was easier because it did not needed water and saved fuel.
De Moerloose certainly trained craftsmen to use professional tools, which also differed from regions.

The hydrogels are polymeric materials having capability to swell in water, i.e. they do not dissolve in water in spite of retaining a momentous fraction of water within themselves [22].
Electron beam irradiation technology was also applicable to purify the waste water by removing some metal ions such as Cu2+, Sr2+ and Co2+ from waste water.
Some of them are to address the market in a consistent manner, to be more judicious in the selection of areas for application development, to emphasize energy efficiency, training of professionals, regulatory hurdles and others.
This technology is also highly acceptable in the field of waste water treatment.

From 1964 to 1987, Water Resources Research Institute of Jiangsu Province had investigated the 61 tide locks for the durability problem and found many problems [13].
In November, 1992, Concrete Durability Professional Committee, Concrete and Pre-stressed Concrete Institute, China Civil Engineering Society Institute, was set up in Jinan.
Although the results are not all identical, there is a common understanding that the reinforcement will begin to rust under the action of oxygen and water after the passive film of reinforcement is damaged.
Amending the oxygen absorption rate of water film by the solubility of oxygen in the water, assuming the relative humidity of air as a random variable, assuming the control after cracking still as oxygen diffusion and assuming the oxygen diffusion along the steel bars around, they built the reinforcement corrosion prediction model.
Thirdly, the water needed for the reinforcement corrosion is adequate when considering the relative humidity in the environment than steel corrosion critical relative humidity.

Initially, aggressive fluids (water, ionic solutions with dissolved salts, gases) need to penetrate or be transported through the capillary pore structure of the concrete to reaction sites (e.g., chlorides penetrating to reinforcement, or sulfates penetrating to reactive aluminates) prior to the actual chemical or physical deterioration reactions.
In the cases of tunnel liners, pipes, and slabs-on-grade, wick action from the air boundary can accelerate chloride ingress by evaporating water from the near-surface capillary pores, leaving behind a buildup of precipitated chloride salts [13,14,15].
Useful information on concrete uniformity and air content can also be obtained from measuring the fresh density of the concrete, and some owners, such as the New York/New Jersey Port Authority have adopted the AASHTO microwave test to determine the water content of the delivered concrete [25] (as a partial check on w/cm (assuming that the cementitious materials are typically batched accurately) related to unintentional or deliberately added water).
There are no instant tests for most of these properties so the monolith approach allows the Owner’s design professional to check all the specified properties of the mixture that the contractor proposes to use.
