Indigo works by a chemical reaction called oxidation-reduction.
Upon reduction, indigo becomes colourless and water soluble.
Results and Discussion UV protection property The UPF values and protection data of cotton fabrics dyed with and without a metal mordants agent are shown in Table 1.

Introduction The possibility of recovering spent ionic liquids has led to the reduction in the amount of waste produced for a particular application.
The data were compared with the values of water content in pure and spent ionic liquids.
We observed that there are changes in DBT peak area which indicating the reduction of DBT amount in the ionic liquids.

Unfortunately, for component such as antenna it is very difficult to fulfill these requirements, so reduction of the dimensions is an actual problem.
Negative impedance converter[11] Basically, the idea of using Non-Foster matching is simple and based on the reduction of the reactive part of antenna input impedance by connecting the antenna terminals to active matching circuit that consists of converters.
Using these data we can get equivalent circuit model of our antennas, as it is shown in Fig. 4.

Over 4 tests were performed on all samples, and average of obtained data is presented.
According to these findings, an increase in the films hardness can be related to the reduction of grains size in the Cr-N films.
The study of chemical composition and surface morphology showed that these behaviors were due to the reduction of grains size with deposition power.

Reduction of pressure in a coal seam by a mine shaft or wellbore will first mobilize water in the cleats, followed by gas desorbed from the matrix.
Pressure reduction in a coal seam sufficient to liberate gas from the matrix into the cleats initially results in a low gas saturation and hence, low gas mobility and low initial gas production rates from a well.
From historical data, additional recovery from ECBM is ~10-20 % from original gas in place.

In other words, with an increase in the tempering time, longer soaking time was required for obtaining maximum toughness, because tempering after DCT caused more reduction in residual stress than tempering after the conventional treatment [7].
But, if reduction in production time and cost was of primary concern, lower soaking and tempering time would seem to be a more feasible option.

Very often it happens that the flow of information between the various stages of the design process was carried out in an indirect way, which entails some disadvantages, such as the lack of real-time feedback between the various stages of the process, problems related to the timeliness of information, or the occurrence of distortions in a data flow.

Compared with IPN, the reduction in ESR from P(NIPAAm/HEMA) was attributed to the increase in crosslinking density or polymer mass per unit volume in the hydrogels, which would decrease the available space for water during the swollen state.
The changes of porous microstructure in all IPN could also be responsible for the slight reduction in ESR.
It is important and practical to examine the drug release data from those hydrogels like the body temperature (37°C).

According to thermo-mechanical fatigue test data of body and weld, equivalent strain range method is applied to predict the residual life of coke tower.

The ideal of SVM is to search for an optimal hyperplane to separate the data with maximal margin.
A SVM is used for each dimension for training and classification, therefore, many SVMs are employed in the whole network space, including SVMs for x dimension of which the training data are {[h( Si, S1), h(Si, S2),…, h( Si, Sk)], cxi} , SVMs for y dimension of which the training {[h( Si, S1), h(Si, S2),…, h( Si, Sk)], cyi }.
By considering the distance vectors in unknown nodes as testing data x , the classes of three coordinate values are attained according to Eq.(3).
The basic principle of SVM fast classification method is searching for a reduction vector set containing less support vector, and then replacing the original support vectors.
Similarity matrix C composed of similarity coefficient is the data base of the proposed method: (8) Where C is a symmetric matrix.
