The specimens were then washed under running water and dried using absorbent paper.
Pouring a Polident tablet (GlaxoSmithKline, United Kingdom) into 150 ml of distilled water yields an alkaline peroxide solution (Fig. 2).
The specimens in Group C were the control group and were cleaned by immersing them in distilled water for 3 minutes.
This erosion can create many pores, making it easier for water molecules to penetrate the acrylic resin material.

Water coal and accumulation of fragment coal Due to water bursting in underground coal mining face or other reasons, there is sometimes a lot of water in the coal stream.
When the moisture content in the raw coal is greater than 20 percent, the coal-water mixture is presented as a fluid viscous state, commonly known as water coal [5].
If there is too much water coal, it is very likely to give rise to a belt slip, silt coal at the tail end of the conveyor, and other accidents.
Furthermore, in the process of coal transmission, due to the low friction between water coal and the belt, water coal is being accumulated at the tail part of the conveyor and finally collapse, threatening mine production safety seriously.
The principle is using professional cameras to monitor main factors leading to coal mining conveyor belt accidents like belt longitudinal tear, transversal fracture, and etc., and then detect possible anomalies and belt damages, such as foreign bulky and sharp objects, water coal, the accumulation of fragment coal, and etc., through high-definition image processing.

A CSR-oriented motivates and reward systems impels managers and workers to seek after projects that can deliver socially responsible results as opposed to those more inclined to produce hostile results, for example, water or air contamination and mismanagement of available resources.
All questionnaires were supervised by practicing professionals before data entries were made.

By considering factors such as initial moisture content, temperature, air velocity, and crop characteristics, along with employing appropriate mathematical models and experimental techniques, researchers and food industry professionals can enhance the efficiency and effectiveness of food drying operations, contributing to the production of high-quality, shelf-stable food products.
The solvent or water that has evaporated while the body is being worked on is also removed by the working fluid and moved outside the dryer.
Hvap=2260kJ/kg is the latent heat of vaporization of water, Cpa is the air's capacity to hold heat.
It is extracted from the surrounding air as it moves past the material and is dependent on the type of material, water present, and temperature.
Moisture Content The term is used to indicate any volatile liquid or vapour content of a substance to be dried and does not always refer to water.

The challenges in developing hydropower for energy security in Aceh are highly relevant, given the region's abundant water resources.
Results of mapping challenges in Water Energy Development for Energy Security in Aceh.
Human Resource Expertise The lack of skilled and professional personnel in the energy sector is one of the main obstacles hindering the implementation and management of energy projects in Aceh.
Hydroelectric power sources, which harness the flow of water from rivers or dams, are highly susceptible to changes in rainfall patterns.
Droughts can reduce the flow of water needed to drive turbines, while floods can damage infrastructure and force temporary shutdowns to prevent further damage.

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.

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.
