Then, the temperature of the alloy liquid cooled to the given pouring temperature, and the alloy liquid was poured into the water-cooled serpentine channel.
After that, the collective mold with slurry was rapidly placed in a water pool within 2~3 seconds to retain the slurry microstructure at high temperature as far as possible.
The water-cooled copper serpentine pouring channel had three curves along the inner channel.
The area A and the perimeter P of every primary silicon grain on a photo were automatically measured by a professional image analysis software.
When A390 alloy liquid is poured into the water-cooled copper serpentine pouring channel, the superheated liquid will flow down along the inner wall of the channel.

Generally, on land wire is insulation, but because of hydraulic pressure increases in the water, small damage may cause leakage and make the ignition failure.
At present, according to strict national standards, these equipment are produced by professional manufacturers.

But the crawler crane has double requirements in large professional and complex work and safe work in all complex work condition.
Many scholars researched in different fields for comprehensive evaluation achieved good results by IAHP of 3-scale, such as Yuanjiang Chen took advantage of the improved 3-scale AHP for comprehensive evaluation of highway construction environment [1], Li Zhang evaluated urban power system by improved 3-scale AHP [7] and Sha Yao took advantage of the IAHP for fuzzy comprehensive assessment on water quality transferring project [6] and so on.

The accuracy of the monitoring data, the understanding of the monitoring data and the reliability of the professional prediction model are the key to early warning system for landslide monitoring.
Usually the monitoring work starts from the following aspects: geological trail monitoring, surface deformation monitoring, deep displacement monitoring, groundwater monitoring, the sound monitoring, stress monitoring ground water, surface water monitoring, meteorological monitoring and monitoring of human activities [6].
Mainly include digital terrain models, satellite images, boundary line, water, vegetation, railways, highways, administrative divisions, residential areas and other spatial information, and attribute information like geomorphological conditions, climatic conditions, population density and socio-economic data, etc.
We collect the basic geographic data (topography, geomorphological, transportation), basic geological data (structure, faults, stratigraphic information), engineering survey data (drilling, profile, test data), and the monitoring data gained from the monitoring instruments, such as water level observation instrument, drilling inclinometer, GPS displacement monitoring, distributed fiber optic monitoring, TDR Time domain reflectometer monitor, 3D laser scanners, SNMR monitoring, surveying robot, thermal infrared monitor etc.

It is speculated that antimony could be a natural contaminant with arsenic in some drinking waters.
The prepared samples were placed on a water bath constant-temperature oscillator at 200 rpm at 25 ℃.

When mixing mortar with new and innovation material, property specification which classifies mortar by performance (compressive strength, water retention, and air content) is preferable [8].
The cement-to-fine aggregate ratio was 1:3 (by weight), and cement for construction professionals CEM II/B-L 32.5 R was used.
Sandy clay was dried naturally under the sunlight for one to two days to ensure there is no any effect on water- cement ratio during mix design.
According to BS [18], the mixing proportion of the cement and fine sand for mortar is 1:3, while water content was determined based on workability test.
All specimens were cured under the water until the testing age, which is 7, 14 and 28 days.

The research aims to provide valuable insights for engineers, architects, and construction professionals interested in sustainable materials, offering a comprehensive understanding of the challenges and advantages associated with recycled concrete in high-temperature environments.
This strategy not only reduces the demand for natural resources, such as gravel and sand extraction, but also minimizes the amount of construction and demolition waste that ends up in landfills, thus contributing to the reduction of soil and water pollution [16].
When the aggregates are extracted from the quarries, environmental problems are caused, such as geological erosion, water and air pollution, vibration, noise and modification of the landscape or environment.
The plasticizing admixture was used to reduce the amount of water in the mix.
This method consists of subjecting the recycled aggregate to hydrochloric acid for 24 hours to then separate the adhered mortar by washing with water.

Drug Center Co., Bangkok, Thailand) was used as surfactant for water phase.
The water phase was prepared by adding the water soluble ingredients and heated in the water bath to 75ºC.
The water phase was added into oil phase and mixed using a homogenizer for 5 min at 6000 rpm.
pH value and rheological behavior determination. pH value of creams was measured using a pH meter (Professional Meter PP-15 Sartorius, Goettingen, Germany).

The favourable characteristics of PAT are indeed important as they reduce the dependence on third-party professional services which can be very expensive.
Water with density of 1000 kg/m3 at 25°C was chosen as the working fluid in this study.
As water enters into the impeller, the pressure decreases along the impeller channel due to conversion of energy from fluid energy to rotational mechanical energy.
The velocity vector of the water entering the pump inlet reveals no sudden change in flow patterns, with a smooth velocity transition.
The water is directed by the curvature of the volute wall (which has a spiral shape) and thus maintains an even flow path to the impeller.
