Salinity caused reduction in germination percentage, germination rate, root and shoot weights in plants [8].
Data analysis Data were subjected to a two-way ANOVA using the SAS™ software (SAS Institute Inc. 1989).

Setup reduction programs have substantially reduced setup and changeover times in many production environments so that more companies can use a make-to-order production control strategy.
For a data-value , we can determine the support boundaries in terms of , otherwise known as the membership grade of any set-point contained in the fuzzy set , , the left offset, , the right offset, and , the centre point.
The same input data used for the deterministic demand model, with Coefficient of Variation less than 15 percent, was also assumed in the fuzzy model.

Discussion Figure 8 exhibits the kinetic fitting curve of the experimental data of catalysis, fitting the formula , where C0 refers to the initial concentration of the organic solution, and Ct refers to the concentration of the organic solution at reaction time t.
These VO states trap light carriers, suppress the recombination of carriers (as seen in Fig. 9a) and assist in the surface photocatalytic oxidation reduction process (as seen in Fig. 9a), thereby enhancing the photocatalytic activity of the sample[31].

In another series of tests conducted by the US Defense Threat Reduction Agency, several different types of steel moment resisting connections were first subjected to a blast then loaded in catenary mode to determine their residual strength ([69]).
Early research in this area was quite limited, primarily because of the difficulty of obtaining high quality experimental data and setting up and running meaningful simulations of progressive collapse.
· Perhaps the greatest need at the moment is high quality test data at the component and system level.

Moreover, not only the resultant coating properties as a function of applied process parameter were investigated, but also a quadratic regression model was derived by statistical evaluation of the experimental data, which is expected to enable deposition of coatings with predefined i.e. tailored mechanical properties.
The indentations were performed using continuous stiffness measurement (CSM) technique with standard parameters (45 Hz, 2 nm) and mechanical properties, H and E, were evaluated from load-displacement data according to the Oliver-Pharr method [17].
The columnar microstructure is typical for this type of coatings and is discussed to be responsible for the reduction of residual stresses [13].

This is the reason why it is fundamental to take into account the following parameters when a new building envelope has to be designed: ü the climatic data (temperature, relative humidity, winds, solar radiation, etc.); ü the shape of the building envelope versus the climate area features; ü the building materials and the compatibility between themselves.
This can allows to assert that the reduction of the pore radii corresponds to an increase of the relative humidity in the pores themselves up to a condensation.
In order to assess the hygrothermal behaviour of a building material the following input data of the material are requested: ü Bulk density, ρs [kg/m3], ü Specific heat capacity, cp [J/kg K], ü Thermal conductivity (dry and wet state), λ [W/m K], ü Bulk porosity, n [m3/m3], ü Sorption isotherm curves, ü Water vapour permeability, δp [kg/m s Pa], ü Liquid diffusivity for uptake and redistribution process, Dw [m2/s].

Load-ram displacement data were recorded for each extrusion.
Worth noticing is the study by Osawa et al.[24] of forged PP that displayed strong loss of turbidity as a result of strain-induced spherulitic size reduction.
The measured load–displacement data were converted to average stress-strain curves.

Table 3 Relative intensity data of the deconvoluted C1s spectra of untreated, air (40s), N2 (40s) and H2O (40s) plasma treated wool.

LTP treatment of wool could increase the apparent dyeing rate by reduction of the surface barrier effect without any change in diffusion rate within the bulk phase.

This apparently suggests urgent needs for further reduction of waste generation and development of waste recycling.
Another requirement for the planning approval was relaying real time emissions data (NOx, SOx) to local government offices.
Emissions data are also constantly displayed on the operation consoles of the plant and monitors in a reception room for visitors and local residents as reference.

The main peaks in the diffraction pattern of TiO2 NPs prove the formation of TiO2 in the anatase phase according to data from the Joint Committee on Powder Diffraction Standards (JCPDS) No. 21-1272.
Fig. 1 XRD patterns of TiO2 NPs, activated carbon and 7.5 wt%-AC/TiO2 nanocomposite Based on XRD data results, the average crystallite size of the TiO2 NPs and 7.5 wt%-AC/TiO2 were calculated by Debye Scherrer’s Eq. 2.
During the photocatalytic degradation experiments the absorbance peaks of chlorpyrifos decreased indicating a reduction in chlorpyrifos concentration.
