The soil possesses the characteristics of weathered, water softening and sharp reduction in strength [9-11], presents the appearance of mostly red, dark red, brown or other colors.
As the weathered red sandstone soil was featured by sharply reduction in strength under the weathered, water soften conditions, it is important to carry out water stability test.

The temperatures in the contact zone are beneath 500ć, which has been verified in tests with thermocouples in the contact zone. 36 Machining of Natural Stone Materials Fig.3 Wear of the wire sawing tool beads machining steel components Macroscopic Wear The reduction of the tool diameter and the conical generation of the cutting bead can be seen as macroscopic wear.
The diameter reduction of the sintered cutting beads during wire sawing of austenitic steel is much higher than using electro-plated beads [17].
Key Engineering Materials Vols. 37 Fig.4 Cutting capacity depending on working pressure Different Diamond Concentration at Wire Sawing Tools The concentration data indicates the volume of diamond in the grinding layer.

The data of coal seam obtained during CBM extraction can be used to enrich the information of coal mine, such as water, rock structure and coal seam structure, which assists to solve the other kinds of problem of coal mine disaster.
Even in the background of implement of energy-saving and emission-reduction and energy consumption control policy, the domestic coal consumption still increases by 200 million ton every year.
CBM development and utilization is beneficial to the alleviation of China’s energy tensions and the reduction of environment pollution to mining area, and it also beneficial to the safe production and financial profits.

Some thermodynamic and kinetic data of Ti alloys may be found in previous research work [6-14].
Experimental Isothermal compression, to 60% reduction of cylindrical Ti6Al4V samples of 10 mm diameter and 15 mm length, was performed by means of a Gleeble(TM) 1500D thermo-mechanical simulator, according to treatment condition A (Table 1).
The surface and free energy reduction are the driving forces for this concurrent deformation-transformation process.

In order to address the issue of energy efficiency in buildings and carbon dioxide emissions (CO2) reduction, the Malaysian Institute of Architects (PAM) and Association of Consulting Engineers Malaysia (ACEM) set-up a regulatory body green building index (GBI) to rate and assist in the development of green building in Malaysia.
For example, when a goal on energy reduction is set (conceptualization), engineers who have design skills are needed while technicians take charge of maintenance and operation.
The data was coded into Special package for social science statistics (SPSS) and descriptive statistics analysis test was performed to determine mean difference that exists on the various low carbon skills considered in the study.

Figure 4.Cross section of the flexible tube Pt is the total pressure (P + Pi) to be applied on a section to achieve a reduction in diameter and it is assumed that this is attained by ‘n’ number of SMA wires surrounding the tube over a length of L of the tube as shown in Fig. 5.
From (10) which gives the force that is to be applied by each SMA wire to get a reduction in diameter of the tube by a factor K, the amount of voltage to be applied to each SMA wire is calculated.
Further work aims at developing the prototype and to carryout experiments with various liquids and compares the results with theoretical data which will be made available in future communications.

Moreover, the different contributions of the strengthening mechanisms have been estimated, showing that reduction of precipitation hardening at coiling temperatures lower than 625ºC can be the cause of significant mechanical property impairment in the high Ti steel.
Due to this, the amount of Nb in solid solution available during phase transformation is lower, which results in a reduction of the hardenability effect that Nb in solid solution exerts.
For calculation of dislocation contribution, Taylor’s equation and the following approach for calculation of the dislocation density (ρ) from EBSD data has been used in several works [5, [] N.

The mechanism of electrodeposition of the binary Ni-P alloy coating can be described by the reaction of nickel ion reduction to metallic nickel: , (1) and the incorporation of phosphorus from the galvanic bath containing sodium hypophosphite: . (2) Phosphorus is the non-metal element which cannot be deposited alone from its aqueous solution without nickel as it is predicted by the theory of the induced codeposition [6,10,11,15,16].
The induced codeposition of the Ni-P alloy coating can be described by the following total reaction: . (3) The mechanism of the induced codeposition of the ternary Ni-Co-P alloy coating can be described by the reaction of electrodeposition of individual nickel (Eq. 1), phosphorus (Eq. 2), and cobalt metal: . (4) The electrodeposition of the Ni-Co-P alloy coating is described by the following total reaction [16]: . (5) In case of the electrodeposition mechanism of the ternary Ni-W-P alloy coating, beside the raction of nickel reduction (Eq. 1) and induced codeposition of phosphorus (Eq. 2), the following reaction of tungsten electrodeposition takes place [17]: . (6) The total reaction of the electrodeposition process of the Ni-W-P alloy coating is as follows: . (7) It should be added that in accordance with literature data to explain the electrodeposition mechanism of the Ni-W-P alloys an assumption is made that nickel and tungsten form a mixed complex in galvanic bath

As a matter of fact, enhancement of quality level in structure construction will decrease the investment in material in later working procedure directly, including reduction in plaster, as well as the thickness of leveling course and the cushion. 3) A sound institution on material safekeeping and receiving was established.
According to the geological survey report and depth of adjacent pile in the actual situation, definite depth in penetration was determined, frequent monitoring was carried out and real-time feedback monitoring data was recorded.
The project department adopted a series of control measures starting from the source of noise. 2) Construction scheme after optimization greatly simplified the construction process and achieved a better noise reduction effect. 5.4 Light pollution 1)The range of temporary lighting was strictly controlled at the construction site.
