The main difference between them is the fundamental data used and the decomposed effects.
Methodology and Data Structural decomposition analysis based on input-output model.
Data Sources.
The contribution of the emission intensity is 75%, which reflect the improvement of efficiency of energy use during the period, and the domestic demand factor contributes 35% reduction to the total change.
We find that energy intensity and domestic demand structure are the main reason of the reduction of carbon emission.

This behavior, also named collapsible behavior, is caused by a suddenly reduction on the void ratio (e) and occurs for soils with metastable structures.
Confined compression curves are presented in logarithmic scale: in horizontal axis is represented the stress data and deformation in vertical axis that is expressed as a fraction of void ratio for a determined stress and initial void ratio (ei/e0).
Soil+RHA specimen presented for the same test condition just 0.058 of deformation (e/e0), representing a reduction of 74.4% in the collapse settlement due the use of RHA.
Computing these coefficients for the tests performed for both specimens, the obtained data are showed in Table 1.
Specimens Cr Cc Cd Soil 0.04 0.67 0.027 Soil+RHA 0.05 0.46 0.017 Assessing the obtained data from Table1, it can be noted negligible differences in the recompression (Cr) and discharge process (Cd).

The system then uses this data along with the density of the metal to estimate the equivalent diameter of the detected particle by comparing it against reference standards of known size and density, such as Gold or Silver nanoparticles [4].
Each sample type is analyzed >20 times on the ICP-MS to ensure good statistical confidence in the data reported.
Based on this data, following observations can be made: a) A majority of the metal particles (~79%), regardless of metal type, are present in the high purity grade of 30% H2O2, and are < 30 nm in size: a.
The effect of the filtration is best exemplified by Cr-containing particles, where there is a reduction of overall particles by 97%, and specifically particles >30nm reduced by 98%.
A very similar trend is also seen with Fe-containing particles, where there is an overall reduction of 82%, with >30 nm reduced by 93%.

Thus, contradictory needs which are, in addition to compliance with particular light intensity per area, uniform light distribution, glare and skyglow (light polution) reduction, can be fulfilled more easily.
Simultaneous energy consumption reduction and safety increase can be provided by implementing lighting control in parks, making areas surrounding people well illuminated while other parts with lights turned down to minimum or off.
Another aspect of outdoor lighting control regards how information about light point distribution, their parameters, available modes of operation and sensory data, including geospatial distribution, is accessible to controllers and how controllers interact with each other.
Such a profile is defined by both the existing lighting standards, obligatory for a given area road class and by an environment state expressed in terms of sensory data: weather conditions, traffic intensity and other parameters.
The solution is based on formally defined data structures being graphs which can be easily processed in order to find proper parameters for light points leading to energy consumption reduction and feature rich control.

The stability of the colloid solution was determined by the data of zeta potential and hydrodynamic size of particles using Zetasizer Nano («Malvern Instruments», UK).
Diameter of (HA)Ag NPs was calculated using spectral data and gauge dependence of the position of the absorption maximum of the plasmon resonance band of the diameter (l max of d) prepared according to [4].
(HA)Ag composite was fabricated by the reduction of AgNO3 with hydrazine hydrochloride, glucose and glycerol.
When the assessment was performed using the spectral data (Table 1) and the calibration curve (l max of d), given in [4], it was found that silver NPs presented in the reaction solution with hydrazine are greater (35-40 nm) than in systems with glucose and glycerol (£10.0 nm).
Therefore, in an environment with hydrazine hydrochloride reduction of Ag+ occurs over the entire surface of nanosorbent.

In this article, the satallite gravity data are applied to explain the Longmen Shan Fault zones.
In order to know the subsurface structure above 0.5km, gravity data from global 1-minute grids have been used.
Generally speaking, the observation gravity data need to be corrected (Height correction, Bouguer reduction, Terrain correction).
Therefore, gravimetric methods can be applied to fill out the gap between these data sources.

The results indicate that, the reduction of ceramsite LWAC prism compressive strength is faster than that of cubic compressive strength.
After naturally cooling down to room temperature, there are different degrees of reduction happen for the cubic and prism compressive strength of ceramsite LWAC.
The curves of the cubic and prism compressive strength of ceramsite LWAC test blocks along with the heating temperature is obtained by fitting the test data results.

An estimated global research and development investment of nearly $9 billion per year is anticipated to lead to new medical treatments and tools; more efficient energy production, storage and transmission; better access to clean water; more effective pollution reduction and prevention; and stronger, lighter materials.
Integrated nanosensors are used for collecting, processing and communicating massive amounts of data with minimal size, weight, and power consumption Magnetic random access memory (MRAM) enabled by nanometer‐scale magnetic tunnel junctions that can quickly and effectively save even encrypted data during a system shutdown or crash, enable resume‐play features, and gather vehicle accident data [6].
Nanosciene can contribute to the further reduction of combustion engine pollutants by nanoporous filters, which can clean the exhaust mechanically, by catalytic converters based on nanoscale noble metal particles or by catalytic coatings on cylinder walls and catalytic nanoparticles as additive for fuels.
A reduction of energy consumption can be reached by better insulation systems, by the use of more efficient lighting or combustion systems, and by use of lighter and stronger materials in the transportation sector.
Nanotechnological approaches like LEDs (Light-emitting diodes) or QCAs (Quantum Caged Atoms) could lead to a strong reduction of energy consumption for illumination [1-2]. 2.4.

Calculation and statistical analysis.CH4 concentration of samples was measured using a SP-2000A Gas Chromatograph system (Manufactured by Shandong Lunan Chemical Instrument Co., Ltd) with a flame ionization detector (FID), and CH4 variation rate is determined by linear regression using four CH4 concentration data points and corresponding sampling interval.
Only when the correlation coefficient R2 is larger than 0.9, the slope can be used as for that set of data(Zou et al., 2004;Lu et al., 2000).
Results of paired t-tests on these measured data show that the CH4 fluxes under CI and FI conditions were significantly different (p=0.016<0.05 for 2005 and p=0.000<0.01 for 2006) and the former were far less than the latter.
In this study, a mainstream water-saving rice production system in a key rice area is investigated; the findings provide practical emission mitigation options and data for an accurate estimate of emthane emissions from rice fields in China.
