Introduction Activated carbon fiber is widely used for a number of applications, such as separation of gases, recovery of solvents, and removal of organic pollutants from drinking water, and as a catalyst support, among many other applications because it has high surface area and adsorption capacity, as well as very high rates of adsorption from the gas or liquid phase [1].
Therefore, there are an increasing number of studies related to the preparation of activated carbons by chemical activation with KOH [2-9] and, more recently, also with NaOH [2, 4, 6, 7, 10].
Therefore, the creation of crystal nucleus has closely (a) (b) (c) (b) (a) relation to the oxygen-containing group on ACF, and the growth speed of crystal grain is determined by the reduction potential of ACFs.

The previous studies showed that magnesium oxychloride cement and products on its base possess a number of unique properties: high ultimate strength, high rate of strength development, the possibility to use both organic and mineral aggregates, fire-resistance, abrasion resistance, etc [4, 5, 6, 7, 8].
The number of samples was chosen so that within-run CV did not exceed 5%.
The capability of caustic magnesite to absorb liquid intensively while gauging leads to the grain formation that is binding material of the tough reacted sheath which stops further hardening and keeps the mixing water away from the active part of the binding material.
Some time after the magnesium oxychloride cement has set and formed the strong stone material, the reacted film on the surface of the magnesite grains dissolves gradually and the active nucleus enters into reaction.

Local strain in cutting zone is estimated by measurement of deformation of metallographic cut using stereological evaluation of the grain boundary orientation.
The size, number and type of the elements used in the mesh play a significant role in the simulation outcome as well.
As a rule, a large number of small-sized elements increase accuracy but also increase computational time.
For gain boundaries orientation in deformed places can be used polygon pattern where the size of polygons is approximately some like grain size.

When the annealing temperature is close to Tβ, the size of βt and αs grow up significantly, and the number of interface decreases, which will reduce the strength and plasticity at room temperature.
It's known that boundary strength is greater than grain strength at lower temperature, and both of them decrease as deformation temperature increasing.
Since boundary strength decreases more rapidly, grain strength exceeds boundary strength at higher temperature [9].
This makes the number of αp/β phase boundary decreases, which will reduce the decline of tensile strength at 650℃.

A great number of Eco-industrial demonstration parks (EIDPs) have been built across China in order to set examples for the full implementation of circular economy and eco-industry.
It is one of the important bases both for national commodity grain and for corn export, green food base in Jilin Province and national demonstration zone for high quality and efficient agriculture as well.
In addition, Songyuan is in the gold maize area in the world and an important base for marketable grain in China.
Keep the EIDPs which have been built and meet the requirements of the planning, reduce the number of EIDPs and provide more support in finance and policy to those eligible EIDPs.

A large number of unpublished studies have been carried out by one of the authors in the course of work on the restoration of doors and it is our eventual intention to review these as a prelude to developing a typological study of their carpentry.
The first will be provided by the sum of the resistance to rotation of the large number of lap joints between muntins and ledges and so depends for its continued action on the tightness of fit between them.
The top and bottom hinges had a greater number of fixings suggesting that they were seen as the principal supports.
There is always a problem with joints in curved timbers because short grain timber within the joint tends to split, and this had occurred in this case.
With halved joints the ledges will be in compression vertically across the grain, as shown and the muntins similarly in compression horizontally across the grain.

This paper presents the dynamic precession of the moments of the grains based on LL equation.Under microwave-assisted reversal conditions, the influence of the differences between the angle of Anisotropy field on the magnetic moment reversal and loading speed of reversal magnetic field in two interacting particles is investigated.

The average grain size was calculated to be 5.5±0.5 μm and 6.1±0.4 μm for AM50 and AM60, respectively.
Increasing of Al content did not cause any significant change in the alloy's microstructure; however, it is reasonable to suggest that the number of β-phase particles has been enlarged.
Ca additions tend to refine the microstructure, however Baek et al. [37] reported no change in the average grain size of wrought AZ61 after alloying it with 0.1 and 0.5 wt% Ca.
It is interesting to notice that the values average grain size of AT51 and AZ51 alloys are close to that of AM50 alloy, and the average grain size of AX61 is same as of AM60 alloy.
This observation suggests that increasing of Al content has more effect on the grain size, than additions of minor elements.

In order to produce samples, annealed steel powder with a grain size 125-250 microns was used.
During the study sample loading force, elongation of the extensometer base and the number of cycles to crack initiation and destruction of samples were recorded.
They showed the dependency of the deformation amplitude εa of the number of cycles Nf0 to a completely fracture of the specimen.
Graph of the fatigue life of sintered 316L stainless steel with a porosity of a) 41%; b) 33%; c) 26% (in the case of the symmetric tension-compression) Also the number of cycles in which a sharp decrease in maximum stress was observed, were recorded too.
It also observed that with the increase in the density, the number of crack initiation and destruction increases.

Distribution of big grains of aggregate along the walls of moulds and on the surface is not so thick as inside the concrete.
These results indicate that concrete surface can be covered in specific level and made more resistantly to specific numbers of cycles.
