The efficient application of MMAL is based on time and expense’s substantial constriction of replacing mould, tool, equipment and material.
Thus it can better ensure more excellent individuals be inherited to the next generation Step 6: Crossover Operation The crossover operation plays a key role in GA, which is the main method to generate new individuals.

Materials and methods Site description With the Three Gorges Dam fully functioning in 2010, the water level fluctuates from 145 m in summer to 175 m in winter, resulting in formation of the riparian zone with a total area of 344 km2 in the reservoir [20].
Natural release of metals by the process of rock weathering, soil erosion or the dissolution of water soluble salts [28,29] is limited, because natural process of weathering of crustal materials is slow and occurs over time.

Introduction The improvement of mechanical properties is a key issue in the development of metallic materials.
Fully recrystallized samples with initial grain sizes of 20, 22 and 41 µm in the IF steel, 2N-Al and 4N-Al, respectively, were used as starting materials for the ARB process.
Fig. 9 shows the engineering stress-strain curves for the IF steel (Fig. 9a), 2N-Al (Fig. 9b) and 4N-Al (Fig. 9c) samples.
The stress-strain curves of the coarse grained samples used as starting materials for the ARB process are also included in Fig. 9.
For all these materials impurities are present in different concentrations, and precipitation hardening during annealing can therefore not be excluded.

Nano particles made of high thermal conductivity materials and their increased fraction in pure fluids enhance the thermal conductivity of the nano fluid [3&4].
The thermal conductivity of nanofluids varies with the size, material of nanoparticles as well as base fluids.
The agglomeration of nano particles is a key issue which is to be avoided in the nano fluids.

Separate collection of HHW on manual pipeline during selection of recyclable materials is not provided.
Collecting and recycling of household waste paint and varnish materials and household chemical residues, generated in the population, in Russia is not established.
For example in UK there are special Household Waste Recycling Centres that accept a long list of different paint and varnish materials [32].
The collection and processing of technical oils as a component of HHW in General is similar to waste paint and varnish materials.

The main aim of these technologies is to create the generation of “smart” materials and, based on these materials, micro-electro-mechanical systems (MEMS), which possess the functions of sensors, actuators and computational elements built into the physical structure of the material.
