The holes drilled in the periphery of the deposition hole were inclined 10° in order to ensure that the thermocouples were perfectly embedded in the grout material.
FLAC500 is a two-dimensional explicit finite-difference program for engineering and mechanics computation.
Ten material models, including several describing highly non-linear, irreversible response, are built in FLAC500, and new constitutive models can been added via the FISH programming language.
Most practical engineering problems are strictly three-dimensional, but in some cases, it can be simplified as a two-dimensional problem and problem solution becomes much convenient and time-saving.

For CO2 conversion to CH3OH, a variety of features can influence the CH3OH yield [2], including catalyst composition, reaction conditions (temperature, pressure), support materials, surface area, and electronic properties.
Effective feature selection can help identify the key parameters that truly drive the CO2 conversion efficiency, facilitating the design of better catalysts and optimizing reaction conditions.

Hydrologists have long recognized that land use and land cover influence key hydrological parameters like surface runoff and groundwater recharge [2].
Materials and Methods 2.1 Study Area South-Western Nigeria is the focus of the study as shown in Figure 1, covering the six states: Lagos, Ogun, Oyo, Osun, Ondo, and Ekiti, that make up this part of the country.
Another key implication is the need to institutionalize cross-scale coordination between local governments and regional development authorities.
The study highlights the risks of unregulated urban sprawl, including ecological degradation, loss of biodiversity, and disruption of key ecosystem services.

Experiment study of Water Stability of Fiber-Reinforced Asphalt Mixture Yingchun Cai a, Yuanxun Zheng b School of water conservancy and environment, Zhengzhou University, Zhengzhou, Henan, 450002, China ayccai@zzu.edu.cn, byxzheng@zzu.edu.cn Key words: asphalt mixture, basalt fiber, Marshall, high temperature stability experiment, water stability Abstract.
Material and Mineral Mixtures Grading Tradition dense gradation asphalt mixture is a kind of suspension dense framework and widely used in road pavement for its characteristic of better water stability, durability, convenience and so on.
The main reasons are that addition of fiber increases the dosage of asphalt in mixture, which improves the effective film thickness of mineral materials and effectively reduces the possibility of water effective between asphalt interface and mineral aggregate,thus the residual stability of asphalt mixture is increased.

We postulate that the chemistry of the solute-vacancy complexes is key to the origin of the competition between phases in this alloy system.
Positron annihilation lifetime spectroscopy (PALS) is a useful technique for the analysis of vacancy-type defects in materials.
Information is obtained on the vacancy concentration behavior in materials over an extended time period, making it useful for the study of ageing dynamics in alloys, including the early stages of phase evolution.
Variations in the mean lifetime result from changes in the number of vacancies within the material, and also from changes in the nature of those atoms surrounding the vacancies.

Information technology is a key ingredient in this emerging recipe forcompetitive advantage through manufacturing [3].
The decision to make the production planning as a basis for starting production, such as, the amount of raw materials that will be required, the cost components that will be incurred, and the estimated timing of production activities.
Hall explains that the production activities take place in the cycle of conversion of raw materials, labor, and fixed assets which used to make a finished good [5].
So it can be concluded that the production is the process of converting raw materials, labor using the equipment and the rules in order to produce finished goods.

Materials and chemicals Corn gluten meal was a gift from Longfeng Corn Ltd.
Molecular weight distribution of the fermentative hydrolysate Molecular weight distribution of hydrolyzed protein is one of the most important properties in producing protein hydrolysates to be used as functional materials, which has a direct impact on their functional properties.
Because CGM for fermentative hydrolysis was previously subjected to extrusion, it might be assumed that such corn proteins, undergone a fermentative hydrolysis easily, compared with the non-extruded materials.
