The data reveal the presence of a long lifetime component related to the o-Ps.
It is observed that the addition of garlic (or marjoram) oil to β-CD results in a decrease of the o-Ps lifetime which was ascribed to a reduction of the free volume holes from 83.6 to 67.7 Å3 (79.1 to 72.6 Å3).
The same figure condensates data for the encapsulation of both garlic and marjoram oils.
The common behavior of I3 agrees well with the reduction of free volumes in the hollow truncated cone of the β-CD due to the inclusion of guest molecules.

In respect to the current transaction situation, the voluntary emissions reduction business in Shenzhen market is quite limited and deserted, which makes the emission trading market very inactive.
In 2007, California joined the Western Climate Initiative (WCI) regional voluntary GHG emission reduction mechanisms to progressively approach to its emission reduction targets.
In 2008, California Air Resources Board (ARB) developed a “Scoping Plan”, which clearly took market mechanisms and other ways to achieve emission reduction targets.
On the basis of full survey and data analysis, California calculated and delineated a GHG emission baseline to designate the units included in emission reduction program.
If there is no mandatory requirement for emissions reduction, entities involved in voluntary emissions trading is essentially just an act of charity, which has no substantial reduction significance and can’t really play a sufficient role in building GHG trading market.

To verify the diameter data determined by tensile testing an optical measurement of a high amount of fibres embedded in one cross section was carried out. 500 to 1500 dry oxidized fibres (not in a matrix material) were glued on a glass-fibre composite plate and further embedded in an epoxy resin.
The extremely high deviation of measured data is a typical phenomenon for single fibre testing.
and reduction of the fibre diameter starts at 600 �C.
Calculated tensile modulus of virgin fibres is 210 GPa which lies in very good agreement with the relevant product data sheet.
The authors are also thankful to Christina Aust for development a new fibre preparation technique and measurement of fibre cross section as well as statistical evaluation of optical data.

These auhors all suggested calculation formula bending rigidity of ordinary concrete beams by dividing a reduction coefficient on the basis for calculation formula of bending rigidity of ordinary concrete beams in the the code for design of concrete structures(GB 50010-2010) (CDCS).
Because the number of their beams used when doing experiment are limited, the accuracy of reduction coefficient which is obtained by linear regression on the basis of limited number of experimental beams deserves further study.
This paper collected a total of 41 sets of test data of 21 recycled concrete beams in the literature [2-8].
(2)it is impossible to completely explain the reduction range of the deformation performance of recycled concrete beams compared with that of ordinary concrete beams,when only considering the reduction of elastic modulus and bending strength of recycled concrete.
And it is hard to ignore the impact of the reduction of the bond behavior between recycled concrete and rebars compared with that between ordinary concrete and rebars on the deformation performance of recycled concrete beams

Step 2: Data sources and data collection and standardized treatment; Choose work than scheme is the premise of the index system according to the determined indexes data acquisition.
Data is from the design unit.Through the min - max standardization method processing, the original data of linear transformation make them fall into interval [0,100].
Data is from the experts in the field and experts with comprehensive experience and research evaluate indexes for satisfaction score.
Such processing will not change data analysis ability, also accord with the five grade marking system standard for evaluation.
Step 3: Data discretization; For Discrete scores under each evaluation index.

Evaluation of biofilm was assessed through the XTT reduction assay.
Result: It was found that 75-80% candida biofilm reduction was demonstrated at concentrations of 10.5-20 mM vanillin whereas chlorhexidine exhibited 94% biofilm reduction.
A biofilm reduction of 75-80% was demonstrated at concentrations of 10.5-20 mM vanillin whereas chlorhexidine exhibited 94% biofilm reduction.
No biofilm reduction effect was observed at concentration <6 mM.
Data from previous studies have shown that vanillin possesses strong antifungal properties against yeasts and filamentous fungi as well as food borne pathogenic bacteria [12, 13].

Data Preparation The data used in this study includes ecosystem carbon storage (density) data, ecosystem carbon sink data, and carbon sink potential and carbon emission of land use data of Shenzhen.
-II survey data on forest resources and the measured soil data of Shenzhen City.
Ecosystem carbon sink data is simulated by the IBIS model, the data for IBIS includes meteorological data, vegetation data and soil data etc. the routine meteorological data is sourced from China Meteorological Data Sharing Service System (http://cdc.cma.gov.cn/).
Part of soil data is come from the national interpolation data of the fourth National Soil Survey with spatial resolution of 5 x 5 km.
Soil carbon content data is from the measured soil data of Shenzhen [4].

Introduction To either decrease fuel consumption or to make an engineering structure more easily to construct, a reduction of mass for most structures is a major demand and this has become a key driving factor for the design and the application of composites [1].
Now the application of composites has been extended to new areas, for example, aircraft structures in which the utilization of composite materials can result in 30% weight reduction, 30% cost reduction, 50% reduction of carbon dioxide emission and 50% reduction of energy consumption [2].
There are only two experimental data for the case of loading rate of 200 mm/min and our major interests are focused on the cases of the low loading rate (50 mm/min) and high loading rate (350 mm/min).
Result from the linear fitting the relationship between the experimental data of mechanical strength and the loading rate is presented as the red line in Fig.6.

The measuring instrument and a wireless transmitter for sending the temperature data to an external receiver are mounted in the holder, enabling real-time measurement of the internal tool temperature during cutting with a sampling frequency of 100 Hz.
That suggests that a reduction in the thrust force can be expected from a reduction in the feed rate.
Fig. 8 Relation of step feed amount to internal tool temperature Fig. 9 Thrust waveform for one step feed cycle At the feed rate of 0.01 mm/rev, the improvement in hole drilling precision is considered to result from the reduction in thrust force at the beginning of cutting.
Considering a previously reported reduction in tool wear from a reduction in step feed amount [3] together with the results described here, we can conclude that reducing the step feed amount can reduce the cutting temperature and suppress tool wear.
Comparing the data on the rise in internal tool temperature for when the lubricant pool is used and when an external supply is used (Fig. 10), we can see that the temperature rise is less when the external supply is used.
