During the operation process, there are quite a lot of influencing factors, for instance, the upstream and downstream water level, ship size, water level in ship reception chamber and so on.
To achieve the dynamic simulation, parameters like water level, current and voltage should be dynamic.
For example, when we click the “Boat into the chamber” button, the boat in the display area will start to move, but when it reach the reception chamber, there will be a pop-up page “Upstream Status Parameters” showing the dynamic status parameters of the chamber, and when they reach the specified condition(tail-bay bock gate open, downstream docking and seal docking in place, anti-collision beam in place, water level in chamber is between 2.5±0.08m), the next step will be triggered.
It may play the role as a professional knowledge base or a fault diagnosis library for power plant.

Earthships home is built with recycled low carbon materials, and is installed with solar temperature controlling system, optical electricity system, water collecting system, solar water heating system, and sewage disposal system.
Water catchment systems take advantage of Nicaragua’s high quantity of rainfall by keeping it in large cisterns, while water reclamation systems process used water and transport it to a green house filled with fruit trees and vegetable gardens.
In that case, Fig. 7 shows that people can participate in the construction, even build the houses all by themselves, with no professional knowledge.

Abstract.
Selective sponge absorption [8] The obtained nanocellulosic sponge showed excellent oil/water absorption selectivity with high oil absorption capacity, Figure 3.
The mentioned properties nominate it as a material that should be taken into consideration when separating oil and water during all processes where they are mixed.
This especially applies to the unwanted events of spilling oil into water, so these sponges could be used very successfully for water purification.
The nanofibers were suspended in water and fed into a small channel, wide only one millimeter, while water with a low pH value was added through two pairs of channels placed normal to the main one, pressing the nanofibers and accelerating their flow, Figure 4.a.

Liquid chemical toxicity hazard identification
Because of the complex physico-chemical characteristics of bulk, coupled with the spill site on the brink sea, bulk chemical leak may spread on land or into water bodies or through volatilization into the atmosphere, whereabouts and behavior are more complex.
Reactivity may react with air, water or their own; diffusion of volatile vapors in the air may form flammable or explosive gas or vapor cloud.
Bulk chemical spill and hazardous bulk itself related to how much of a risk, the number of leaks, also with the time of the accident, weather conditions, terrain, waters surrounding the accident source, population density within the sphere of influence of the environment, and so on.
This article under a bulk chemical storage and transportation professional terminal of storage and transportation of chemicals and physical-chemical properties, toxicological properties, select p-xylene, methanol as a representation of the risk impact analysis predicting the toxicity material, and simulations.

Walls should be sprinkled with water just before plastering for appropriate bonding.
External tank finishing involved the pointing of the tank and the fixing of the necessary water out let facilities such as water fountain, taps and stopcock (vannes).
It should replace plastic, and rubble stone masonry in the construction of water tanks.
Curved blocks water tanks do not contain corrodible materials to contaminate their contents making it appropriate to collect and store even drinking water.
It is also recommended to all administrative officials, professional engineers and architects, the building contractors, building owners and estates developers to use the concrete window and door frames as an alternative material appropriate for use in various construction projects especially low and medium costs buildings.

Deionized water was obtained from the Mechanical Department, University of Engineering and Technology Lahore.
This is the high-temperature stage; after 30 minutes of stirring at a temperature of 35 ℃, 230 ml of deionized water (DI) was gradually added over a period of 1 hour and 15 minutes, with constant stirring, raising the temperature to 98 ℃.
With the addition of DI water at this high temperature, the color gradually shifted from purplish-brown to orange-brown and then reddish-brown, indicating significant oxidation.
The combination was then given 700 ml of DI water while still maintaining a 98 ℃ temperature.
Expanding the experiment, 30ml of DI water was taken in a beaker and gradually added with 3ml of PVA to a mechanical stirrer, followed by heating at 78 ℃ for 90 min [13]; this way, 10% PVA was prepared.
