The highest intrinsic viscosity and yield of PPSE by the reduction of PPSOESE reached to 0.78 dL/g and 93.2%, respectively, much greater than the reported results.
From these reports, we deduce that one of the best ways to increase molecular weight of PPSE is through the reduction of its sulfoxide precursor.

Introduction With the increase of fossil fuel consumption and the energy price uncertainty, the reduction of available existing energy resources and the exacerbation of the ambient atmospheric environment where the inhabitants dwell have attracted much substantial concerns in the last few decades, and consequently the actions for energy conservation and emission reduction are necessitous and essential for sustainable development of the human beings.
Therefore, with the background of energy structure regulation in China, both the heating system and fuels used need updating in order to gain achievement of energy conservation and emission reduction [5].
On the other hand, the effective utilization of different types of coals is also significant to energy conservation and emission reduction in DH.
In an attempt to fulfill those requirements, the DH system for an economic district of a Northeast China metropolis is utilized as the case study, the its “temperature-heat load-duration” diagram is plotted based on basic meteorological data; the economy-oriented optimization technique is then employed to deal with the coal blending and gas usage problem in DH; finally, the air pollutants emission and total heat supply cost variation trends are further discussed under the different thermalization coefficients of the DH system in this paper.

The reduction factor of pouring thickness is considered excessively and the situation of thickness greater than 4m is not considered.
According to the data comparison, “Building Construction Handbook” and “Technical Specification for Thermal Cracking Control of Mass Concrete of Port and Waterway Engineering”, the temperature rise formulas are modified as following.
The temperature rise reduction coefficients corresponding to different thickness are shown in Table 7.

The reduction factor of pouring thickness is considered excessively and the situation of thickness greater than 4m is not considered.

The reduction was ascribed to the phenolics, terpenoids, polysaccharides and flavones or other poyphenol compounds present in the plant extracts.
Reduction takes place in a few minutes as indicated by the gradual change of color from colorless to yellow and reddish brown of the aqueous solution after addition of napier (P. purpureum) leaf extract.
The rate of the Ag+ ions reduction was slow during the first 5 minutes, as indicated by low absorbance at a wavelength around 430nm as shown in Figure 1.
The inset of Figure 1 illustrates the reduction of silver ions takes place at a faster rate and saturation of data occurs at 240 min which would indicate the completion of reaction.
An immediate reduction of silver ions in the present investigation might have resulted to the phytochemicals like flavinoids, alkoloids, saponnins and tannins present in the napier leaf extract.

The activation energies were determined from thermogravimetric analysis (TGA) data using Kissinger method, which does not require knowledge of the reaction mechanism.
Thermogravimetric analysis (TGA) TGA was done using Perkin Elmer Instrument (Diamond TG-DTA) under air atmosphere at 60 ml/min at different heating rates of 20, 50, and 100 °C/min, and the data of weight loss versus temperature were recorded.
The data were obtained in the temperature range of 34–82 °C.
However, for REMB24 (in Fig. 5(e)) large polymer particles were found with a trend of phase inversion and this phase inversion may cause the reduction of thermal stability, activation energy and stiffness.
The observations under the confocal microscope investigated the microstructures of the neat and modified binders, which reveal that very high modifier addition caused phase inversion, which again caused reduction on the service performance.

The dielectric constant of Al2O3 as determined from capacitance-voltage data was about 8.3.
The roughness of the films was measured by AFM and the data are presented in Table 2.
The CV simulations of the Al2O3/Si system done using the ISE CAD 8.5 software fitted to the measured data yield density of interface states in the order of 1012 cm-2 at the middle of the Si bandgap to about 10 13 cm-2 in the vicinity of the conduction and valence bands.

Nevertheless, reduction of the negative charge and interface traps need further investigation.

According to the theoretical basis of the model, and under the conditions of the basic hypothesis, combined with ion theory, and double membrane theory, the LF refining process dynamic model of liquid steel to phosphorus has been established , and it is also been fitted and validated by using the field test data.
In the process of LF refining, due to the rise of temperature, the reduction of slag oxidation, the balance between the steel slag and the phosphorus is broken, the slag of phosphorus will take into the molten steel ,which will cause the rephosphoration.

The fitting of the model and the application The process of actual production, the LF refining process changing of phosphorus content in liquid steel (excluding changes caused by metal rephosphorization quantity) should follow the section back to phosphorus dynamics equation is derived, which can validate the model applicability under this experimental condition, by using the rephosphorization model with the experimental data to fit, if the fitting effect is good, we can tell the model is correct.
Origin software was applied to the rephosphorization dynamics model with the experimental data selection,“”is the form of fitting, the fitting results are as follows.

Accordingly, this study focuses on the effect of regeneration and cooling of the inlet air on performance of an open cycle gas turbine plant, which mainly includes improvement in its thermal efficiency and reduction in specific fuel consumption.
As an example, 12.89% increase in thermal efficiency is found at a regenerator effectiveness of 0.85 on addition of spray cooler before compression of inlet air at an ambient temperature of 328K, and subsequent reduction in specific fuel consumption is found as 2.85% at pressure ratio of 10.
They emphasised in reduction of the intake air temperature in order to enhance the overall efficiency of any plant.
In case of turbine and compressor, necessary assumptions are presented here as: · Steady state flow · Insulated · Same potential head at inlet and outlet datum Accordingly, under a steady state condition, the energy balance of the air flows from state-1 to state-2 of the compressor is presented here as: (1) Fig. 3 Schematic T-s diagram for the regenerative Brayton cycle Hence, related specific energy balance (energy balance per unit mass) is given as: (2) The considered assumptions lead Eq. (2) to a relation as: (3) Now, size of inlet and outlet pipes of the compressor is to be designed such a way to maintain, which presents the specific energy balance as (4) In case of compressor, work is done on the system.
In brief, in a high temperature environmental condition, adding of a spray cooler before compression is very essential in order to reduce specific fuel consumption that leads reduction in emission of the pollutants.

The theoretical dependence l = l (t) used to calculate the absorption kinetics for any capillary at all its stages that would coincide with the experimental data with high accuracy has not been found until now.
At the same time, decrease in the integration step leads to increase in the number of calculations and in the error due to the limited size of the data storage grid in the computer.
Significant reduction in the integration step is required when the capillary radius decreases.
At the same time, the errors in computation were eliminated by applying the extended (80) data.
Data can be simultaneously displayed and written to a file for later use.
