Composite pastes were cured using a standard 60s/30s exposure and data acquisition of (60 min + 30 min).
Statistical significance of change values was obtained from two-tailed P values using the HolmSidak test for paired data.
This trend is being attributed to the reduction in exotherm of resin polymerization by the filler phase.
It may be prudent to collect data on the water sorption of these materials to establish whether there is a reasonable possibility that the relatively high PS may be offset by the hygroscopic expansion of UPHM resins from water uptake.
Preliminary studies on aqueous immersion of ACP/UPHM composites (unpublished data) indeed indicate an increase in the volume of the composite disk specimens of up to 13 % for both LC and DC formulations.

Organize basic data.
Data resource and data collection Data of Fertilizer application: Chinese yearbook(before 1996);Yearbook of Land Resources in China(after 1996);Xinjiang statistical yearbook (from 2001 to 2013);Xinjiang Production and Construction Corps statistical yearbook(from 2002 to 2013) Data of Water quality: Shihezi Environmental Protection Agency, Shihezi Environmental Quality Report(from 1996 to 2012);Xinjiang environment situation Report; Shihezi environment quality Report; The first national survey of pollution sources of agricultural sources of technical reports, Shihezi,Xinjiang;Soil pollution survey in Xinjiang Evaluation of environmental economical loss on groundwater pollution by abuse of fertilizer Principle and calculation method of concentration-value Loss .In any environment, there are varieties of pollutants, such as ozone-depleting substances, nutrients, viruses, bacteria, heavy metals and other toxic and harmful substances, which will damage the environment under certain concentration
Determination of parameters and :Parameters and should be assessed with measured data(Table 15) .
However, the values of Parameters and were not accurately reflected the toxicity of each pollutant, when data were took from certain area.
If the utilization rate of fertilizer increased several percentage, it will not only mean the considerable economic benefits and capital investment reduction in agriculture, but also reduction of fertilizer pollution load for the ecology.

Fig. 2: Structure Diagram of General Module on Subsystem Fig 3: Process Flow Chart of Underlay Program for Data Center Design Concept for General Module For more easy and flexile expansion of the system, this design makesconsolidated design on the communication and data processing sections, viz., the general module as shown on Fig. 2.
Design of Wireless Communication Board: Both the physical layer and data link layer of the wireless communication protocol are realized with RFIC nRF2401.
Design of Controller Software The upper layer software for the data center is designed with C++Buildr.
Both the PC and wireless communication module at the data center use RS232 protocol for communication.
Both hardware design and software design for the data center were done based on the needs for the design, able to display the hospital indoor environment data on real-time basis through receiving the data sent from the sensor nodes, also acting as a data storage, thus providing highly trusted factual basis for the control unit to make scientific decision and scheduling.

The field data are compared to prediction models.
The testing of paints for prolonging of corrosion protection of weathered galvanized steel structures in real exposure conditions gives important data for long-term durability of large steel structures´ corrosion protection.
The field data are compared to prediction models.
E.g. the planned service life of pole of power distribution network is 50 years and estimated costs to build 1 pole is ca 36 000 € so the prolonging service life for 30 years represents the reduction of cost about 20 000 €.

The data of the mechanical test were analyzed through the study of variance (ANOVA) using the Statistic software version 10.0.228.8.
The compositions with 10 and 15% of oil there suffered a reduction in the amount of Tc, the addition of limonene favors the increase in mobility of polymer chains, which indicates the formation of plasticizing effect on the polymer, favoring, thus, a decrease in the value of Tc, besides a reduction in the degree of crystallinity [8].
According to the observed values for the specific deformation, there was a reduction in its values at all concentrations.
This behavior is best observed with 10% oil, indicating that this percentage favored larger structural discontinuities and a significant reduction in its deformation.
There was a reduction, however, in fracture stress with increasing oil content and the oil decreased the deformation of the films at all concentrations.

Previous research is focused on depositing MoS2-based solid lubricant by Physical Vapor Deposition (PVD) on microstructures and such tools exhibited a 25-44 % reduction in cutting forces while machining hardened steel [9].
A 4-component rotary type 9170A dynamometer (Make: Kistler) measures cutting forces and 3 trials per experiment is conducted to ensure the repeatability of the data.
This significant reduction in cutting temperature is due to the smooth flow of the chips over the rake face and adequate lubrication at the machining zone.
This is a significant reduction due to the collective optimized combination of lower cutting forces, lower friction, retention of the sharpness of cutting tool edge, and smooth evacuation of the cutting chips.
· There is a 75.1% reduction in the flank wear of the textured cutting tool compared with the non-textured tool, and the primary wear mechanism observed in the non-textured tool is abrasion, fracturing, and adhesion

Differential pulse voltammetry (DPV) experiments were performed using an Autolab potentiostat, connected to a PC microcomputer for potential control and data acquisition.
A pair of well-defined redox peaks is observed with oxidation at -0.044 V and reduction at +0.021 V at the MWCNTs-modified GCE (cyclic voltammogram a).
This is owing to the oxidation/reduction of some functional groups on the surface of MWCNTs [7].
At the same experimental conditions, two redox peaks for HQ at bare GC electrode were observed with oxidation at 0.160 V and reduction at 0.210 V.
At the same time, the reduction peak potential shifted negatively with increasing scan rate and oxidation peak potentials shifted positively.

The prediction of the compensation induced hole concentration reduction in implanted Al regions is a key parameter in developing high power SiC devices.
Based on this data a fit function was derived which allows for estimating the compensation ratio for a wide Al concentration range.

The insensitivity at the lower end of the frequency range is evidenced by the scatter in the dielectric loss factor data.
The experimental data show that the dielectric constant reduces about 6% as the frequency increases from 7 to 11 GHz.
In Fig. 3(a), data of dielectric constant obtained from 7 GHz frequency show linear trend.
The data showed a linear relationship between the dielectric constant e¢ and density of the compacted asphalt mixture.
