.%, (ii) the rate of volatilisation of solvent influences the differential shrinkage between layers; in the worst case scenario the base layer has fully dried so that its shrinkage is complete when the next layer begins to dry, (iii) the span between filaments determines the number of welds per unit area and hence overall laminate strength, (iv) as the span decreases and the lattice becomes more densely packed, the vapour transport within the structure decreases and drying rate slows down, in turn reducing drying deformation.
At high porosity, the number of welds per unit area is low and delamination is facilitated.

Measurements were taken at a number of positions in the plane of the crack, at the mid height and mid thickness of the specimens.
To ensure that sufficiently large number of grains is included in the measurements a gauge volume of 2 × 2 × 2 mm3 on specimens 16 and 23 and 3 × 3 × 3 mm3 on specimen 26 was used for ND measurements.
Different gauge volumes were used to optimise the number of measurements can be made during the available beam time.

The number of studies on nanotechnology related to the number of studies on nanotechnology related to the petroleum industry has been growing rapidly in the past few years.
In the petroleum industry, The utilized cement in the oil wells is classified as class G cement, which is different from Portland cement by a low amount of “celite” (C3A) and has larger grains than usual Portland cements [10].
Cement class mixtures were prepared using two different groups of Nano materials, which are (Nano cement dust ,Zno Nano rods) in four concentrations (0.25%, 0.5%, 0.75%, and 1%) per weight .In order to achieve these steps, number of samples were designed for oil well cement class “G” that must apply 792 gm weight of cement and 349 gm water, according to the American Petroleum Institute (API, 1997) in (9) classes, from A to J.

However, many natural phenomena are better described using a dimension between two whole numbers.
When a system builds internal models or internal representations of itself as aid to self-organizing autonomous behavior, the system falls under pressure to develop "realistically" fine-grained self-models because the capacity of the system in question for self-organizing behavior will obviously depend on the extent to which the system can accurately represent the fine details or minutiae of its own structure in its "inner" self-representations.
Such a changing organization structure can always keep the same staff number throughout the project, but can complete all the work. facing a flux state, each organization member is required self-organization and self-control, to ensure the entire organization good operation[5].
Meanwhile, a number of different tasks can be broken into more little projects at the same time, task execution efficiency is improved.

Biological disasters- More than 1,400 types of pests and rodents cause losses of nearly 50 million tons of grain and over 1 million tons of cotton.
The expanded role also means an integration of a number of disciplines and a number of expertises drawn from different areas.

In addition, many studies found that oil hydrocarbons entering the soil scattered the soil grain and reduced water permeability [14, 15].
The results showed that there was no significant difference on the number of the microorganism between the polluted and unpolluted soil, but in oil-contaminated soil, the number of hydrocarbon degrading bacteria significantly increased.
Zhao et al. analyzed the total number of microbe in Panjin reed wetland, and found that bacteria were the advantage community among the wetland soil microbes, followed by actinomycete and fungi [27].

A large number of additives research has been done to improve the anode performance and reduce the anode consumpution, which is based on different effects of some elements at the quality and consumption of carbon anode.
There is not abscission of large grained aggregate coke in the subsequent forced pull-off.
Moisture, CO2, CO, light oil and a large number of micromolecule fugitive constituent are released from the pitch.

Rate of inventory turnover, (quotient of the annual average inventory multiplied by 365 days – number of days in a year – to net revenues from sales of products, goods and materials), which is a measure of the capital efficiency that is employed in company inventories.
Term debt repayment, (the ratio of the average annual state of total liabilities from deliveries and services, multiplied by 365 days – number of days in a year – for net proceeds of sales of products, goods and materials), which informs about the average number of days elapsed since the date of purchase of materials, goods on credit until its repayment.

The increase in the crystallite size is due to the incorporation of Cu2+and is attributed to the creation of tin or Oxygen vacancies and also leads to the assembly of bigger grains of Cu-doped SnO2 compared to pure SnO2 respectively [15,16].
Number of unit cell in the crystal is calculated using the relation n= πD3/6V (4) where D is the crystallite size and V is the volume of the unit cell[18].
The number of unit cell in the crystallite increases as the crystallite size increases and is given in table 1.
