For example, for the alloy Al-6 % Zn- 3 % Mg, plastic behavior patterns which have been studied in depth and comprehensive [1-4], it is characteristic the presence of grain boundaries and subgrains, the presence of particles of different sizes, high initial dislocation density.
It may be noted that in accordance with experimental data , for such e mean free path of the dislocations in the shear zones on the order is less than the size of the subgrains , thereby sliding in the alloy develops as a material which has no grain and subgrain boundaries; i.e. as in a single crystal.
Moreover, for a number of precipitate-hardened materials is known experimental evidence of the formation of point defects in the deformation process and their impact on the characteristics of the dispersed phase [17, 18].

Rapid growth in China’s per hectare chemical fertilizer application,from less than 10 kg in 1960 to more than 800 kg in 2000, is required to increase grain production, but has caused many environment problems[4].
Due to high profit from growing vegetables, fruits and flowers, farmers commonly use high rates of N and P fertilizers, about 10 times higher (average fertilizer application rate is 569-2,000 kg per hectare) than for grain crops.
In summary, in the case of nonpoint source pollution, appropriate regulation must take account of the unobservability and unverifiability of individual emissions.Which of the methods of pollution control is appropriate depends on many factors: information availability, type of resources to be regulated, effectiveness of government management, local economic development levels, degrees of uncertainty, social cost of damage, the number of polluters to be controlled and so on.

The creep behaviors of a Ni3Al-base single crystal superalloy IC6SX prepared by spiral grain selection method was studied systematically under the testing condition of 760℃/540MPa.
Therefore, the stress balance was broken with the number of the dislocations which cut γ′ phase increasing and the dislocation network was destroyed.

Polycrystalline cubic boron nitride compact samples processed in domestic with different grain size are the research object.
We can see from Fig.1, PcBN compact sample surface is flat and smooth before electrical discharge grinding, but after machining, a number of loose and hole, high temperature melting traces, local squamous lines and molten material are shown in the sample surface.

It should also be noted that in this scientific study, a number of experiments were conducted, the change in porosity during the imposition of oscillations was studied, and graphs of the obtained experimental dependences were constructed.
Because when obtaining such materials with guaranteed properties, it is advisable to control the parameters of their structure during the manufacturing process, which include: the density of pressing, the quality of contacts, the size of particles (grains), the shape, the content of components, etc. [9, 10, 11].
Therefore, to improve the quality of the final product, it is necessary to apply vibration oscillations, which will reduce labour costs by reducing the number of technological operations, as well as study structurally heterogeneous materials and predict the porosity distribution in any configuration of the workpiece, regardless of the size and geometric parameters of the bunker [40, 41].
The use of the model makes it possible to reduce labour costs by reducing the number of technological operations, as well as to study structurally heterogeneous materials and predict the porosity distribution for any configuration of elements (round, triangular, square), regardless of the size and geometric parameters of the bunker.

They could enhance the built environment in a number of ways.
Types of green roof and their characteristics Characteristics Extensive Green Roof Semi-intensive Green Roof Intensive Green Roof Soil characteristics - Depth - Grain size - Water retention capacity - Nutrient reserves 150 mm or less Coarse Low Low 150 to 200 mm Medium Medium Medium 200 to 2000 mm Fine High High Fully saturated weight Light (80-150 kg/m2) Medium (150-300 kg/m2) Heavy (300-1000 kg/m2) Plant species Moss-sedum-herbs and grasses Grass-herbs and shrubs Lawn or perennials, shrubs and trees Accessibility by occupants Mostly inaccessible Partially accessible Accessible Cost Low capital and maintenance costs Medium capital and maintenance costs High capital and maintenance costs Structure and Materials of Green Roof The basic components in common of green roofs of any type are illustrated in Fig. 1 and are explicated below.
Amongst various places visited by the delegation, a number of buildings in Tokyo showcased exemplars of green roofs.

The largest number of damages from the earthquake was registered in the buildings built of stone and clay brick blocks.
In the period 1990-2000, because of the wars in the region and the imposed economic sanctions, a large number of individual objects are built of concrete block or clay brick block, that do not have the minimum required compressive strength.
After the earthquake of 1979, the large number of stone masonry buildings was repaired.
In the case of strong earthquakes, it can be expected that the largest number of human casualties and damages will be registered in the buildings with masonry structure.
The testing of aggregates consisted of determining: granulometric composition, fineness modulus (M) and the density of the saturated surface of dry grains (γzz).

Welding process is a multi-field technique mobilizing a great number of electric, thermal and thermo-mechanical phenomena.
These methods are a powerful tool that uses a special design to study the parameter space with small number of experiments through orthogonal arrays [12-13].
In this research larger-the-better is chosen, which can be calculated as following equation: (Eq. 1) Where S/N are the signal-to-noise ratio, n is the number of repetitions for an experimental combination, and a performance value of the kth experiment.
The number of experiments required can be tiny room to 9.
Rolled microstructure of X70 base material is composed of polygonal ferrite α (white color) and pearlite P (black color), containing about 75% ferrite with a range of ferrite grain sizes between 4 to 8µm. 304L austenitic stainless steel composed mainly of austenitic phase γ (about average diameter of 22µm) with a small amount of dispersed carbide particles and precipitated phases in austenite grain boundary.

However, total power control at finer grain size is not described.
To reduce the number of partial product rows, the modified Booth algorithm has widely been adopted in binary multipliers.
The -2A and -A can be done by taking the one’s complement of the number and adding 1 to the least significant bit.
Assume multiplicand A for the modified Booth multiplier has large dynamic range and A is represented as n-bit 2’s complement number (Eq. 1).
The bits number and transition activity are dynamically decreased according to the actual signal magnitude.

Samples and methods 310 grains of the polished and faceted rubelite are selected, and their sizes are in the range of 4 ´ 10 ´ 10 mm to 10 ´ 18 ´ 25 mm, and they don’t have visible inclusions.
