The experimental data are statistically analyzed by using analysis of variance to find out the significant parameters.
Specific properties of natural fibre composite such as light weight, low cost, renewable in nature, high specific strength and modulus have widened their usage and allow a considerable reduction in the use of non-biodegradable polymers and non-renewable resources [3-4].
The experimental data is analyzed using response surface methodology to find the optimal setting of the process parameters for load and stress.

Analysis of optical microscopy and SEM data showed that shear bands are distributed throughout the whole volume of HPT-specimens.
To the best of our knowledge, the highest density of shear bands with a spacings of 30 nm was observed in Zr70Cu20Ni10 amorphous ribbons after high-energy ball milling [20] and Pd40Ni40P20 bulk metallic glass after room temperature rolling at 99% thickness reduction [21].
However, minimum spacings of 30 nm were demonstrated for ribbons with a thickness of 40 μm [20] and samples with a thickness of 10 μm (99% thickness reduction of initial BMG discs with a thickness of 1 mm) [21].

The data show that the permeability coefficient of washed ore is 12.7 times than that of raw ore; permeability coefficient with the compaction degree 38.3% is only 3.78% of that in natural state; Chemical blockage brings about a fall of permeability coefficient by 93.5%, and earlier physical blockage leads to the decrease of it by 43.2%.
As shown, the fine particles in the pore naturally migrate toward pressure reduction direction, and they are captured when coming across the pore with smaller size.
In addition, a part of particles tend to engender surface sedimentation after small particles entering large pore throat, which can bring about the reduction of effective seepage area[10], and the other particles would continue migrating downward.

The corrosion rates, which were calculated from the weight loss data, showed that the inhibition efficiency of the extract increased from 86.9% to 89.0% as the concentration of banana peel extract increased from 300 ppm to 500 ppm.
Among the impact of corrosion are costly maintenance and repairs, shutdown of plants, reduction in efficiency, and waste of valuable resources [1].
Reduction of corrosion rate can be done in many ways, and one of the economical, popular and acceptable practices is the use of corrosion inhibitors.

The large amount of carbon emission resulting from road maintenance needs to be determined with definitive methods and data to form a basis of measurement of the carbon emission of the road maintenance process.
Strong and accurate technical data are crucial in the quantitative analysis of LCRM technologies, which will help to standardize the industry and allow for control and consolidation through government legislation.
The advantages of HUT are high leveling accuracy, anti-skit characteristics and noise reduction features.
Parallel data were obtained for the four different PPM techniques to allow for scientific comparison. 4.
The data obtained in the field showed higher values because of vehicular exhaust, and had to be adjusted using the laboratory tests.

The sintered Ni-20at%Co rod was cold-rolled into tape at 5% reduction ratio with the final thickness of 100㎛, and the recrystallization heat treatment for the development of the cube texture of the rolled Ni alloy tape was carried out at 1000°C in Ar 96% and H2 4%.
X-ray diffraction data of Ni-20at.
The scratched and textured tape resulted in the highest texture development in the diffusion reacted LiNi0.8Co0.2O2 phase while the non-scratched and un-textured Ni-Co tape showed the lowest (00l) peaks development in XRD data.
This texture development of the LiNi0.8Co0.2O2 phase was considered to epitaxial growth of the diffusion reacted region on the c-axis textured substrate with sharp (200). 10 20 30 40 50 60 70 80 Intensity(A.U.) 2 θθθθ ▽▽▽▽ LiNi0.8Co0.2O2 ▼▼▼▼ NiO+CoO (101)(101)(101)(101) (003)(003)(003)(003) (106)(106)(106)(106) ▼ (021)(021)(021)(021) (110)(110)(110)(110) (104)(104)(104)(104) (107)(107)(107)(107) Ni + Co (a) (b) (c) (d) (e) (f) ▽▽▽▽ ▽▽▽▽ ▼▼▼▼▽▽▽▽ ▽▽▽▽ ▽▽▽▽ ▽▽▽▽ ▽▽▽▽ ▼▼▼▼ ▼▼▼▼ 10 20 30 40 50 60 70 80 Intensity(A.U.) 2 θθθθ ▽▽▽▽ LiNi0.8Co0.2O2 ▼▼▼▼ NiO+CoO (101)(101)(101)(101) (003)(003)(003)(003) (106)(106)(106)(106) ▼ (021)(021)(021)(021) (110)(110)(110)(110) (104)(104)(104)(104) (107)(107)(107)(107) Ni + Co (a) (b) (c) (d) (e) (f) ▽▽▽▽ ▽▽▽▽ ▼▼▼▼▽▽▽▽ ▽▽▽▽ ▽▽▽▽ ▽▽▽▽ ▽▽▽▽ ▼▼▼▼ ▼▼▼▼ Fig. 2 XRD data of LiNi0.8Co0.2O2 thin films with different amount of Li source and the surface morphology of the substrate; (a) thermal evaporation

After analyzing the related data of plastic mulching film use, and the status of its’ recovery and utilization in Awat county, presented the optimizing countermeasures from the following aspects: strengthening the propaganda of the harmfulness of “white pollution”, promoting local peasants’ ecological civilization consciousness; developing waste plastic recycling enterprises, broadening the recycling channels; formulating preferential policies to increase the support for waste plastic recycling; controlling and reducing the plastic mulching film residuals from farming techniques; intensifying residual plastic recycling by combining manual and mechanical recycling. 1 The general situation and plastic mulching film use status of Awat county Awat county is located in the south of Tianshan mountain, the north margin of the Taklimakan Desert.

According to "reduction, recycling and reuse of the circular economy concept, accelerate the old polluting plastics recycling, regeneration and recycling use, waste and harm for profit, and promote rural pollution emission, improve the efficiency of resource use, realizing the maximization of resource utilization, recycling and sustainable utilization. 3.2.1 Strengthen the publicity of the harmfulness of "white pollution", enhance the local peasants’ awareness on ecological civilization Although most peasants have realized the harmfulness of residual film, but, as peasants, collecting residual film was just for the sake of their farming, as to the residuals were blown and fell where, had nothing to do with themselves.
