Finally complete the mechanical composition analysis and the structural analysis of the sediments [11]
Compared with other isotopes which make up the tree tissues, cellulose has stable chemical properties and low migration characteristics [14].
It is noteworthy that before determining the value of δD, the α-cellulose should be prepared through nitration because exchangeable hydrogen in the α-cellulose's O-H structure can affect on the result of climate reconstruction [17].
When analyzing hydrogen and oxygen isotopes time series, moving average method is used to eliminate parts of the random factors exist in the measured values, and improve the analyzability of the data [20].
However, there are still some differences in the specific division of various stages and the influential factors still need to be analyzed further.

As a result, the inhomogeneity of thermal properties of the tested component, or the presence of some imperfections, is revealed as temperature variations of the component's surface.
Material and methods The proposed nondestructive evaluation method of anticorrosive Aluminium coatings by pulse active IRT consist of the following stages: - The Visual Test (VT) of sample surface in order to assess the surface imperfection such as spatter or pore and oxide, which could affect the quality of IRT examination.
After filling the holes with lead, the final machining of the calibration block was made and then it is subject to the blasting operation to ensure an appropriate roughness to provide a good support for mechanical anchoring of coating layer on the base material.
As influence factors (IF), the following three technological parameters were chosen: the spraying current intensity, spraying speed (the travel speed of the spray head in relation to the component) and spraying distance (distance between the spray head and the component).
It is well known that the main mechanism to accomplish the adhesion between the coating layer and substrate is "mechanical anchoring" of sprayed molten material particles, achieve during their cooling when they reach the micro-irregularity of the substrate.

The properties of the alternative building wall materials are identified and compared with that of conventional bricks.
Energy is said to be one of the prime factors for the economic development of the country.
It also causes environmental hazards as considerable amount of top soil is consumed which is rich in minerals, thus affecting the natural vegetation.
The use of phosphogypsum increased the unit weight and mechanical strength while lowering the value of water absorption.
The materials were properly weathered and their properties were studied with the help of literature reviews (Annexure-I).

The study on the size and structure of deoxidation products from the sub-rapid solidification will be of great significant in promoting the mechanical properties of the strip continuous casting steels.
The reason is that when the size of most particles is reduced to nanometer, their physical properties will be changed significantly, such as the melting point, which would degrade as a result of nano-effect.
If the viscosity is the primary influence factor for amorphous solids from liquids, the hardening rate could be surmise as the determinant for the mean size of amorphous solids.
The solubility product of silicon and oxygen in steel mainly affects the generate timing SiO2 when the solidification rate is certain. 3.

The resulting experimental data will undergo RSM analysis to formulate mathematical models for predicting WL, CR, and IE across a wide range of influencing factors.
The factors levels is presented in Table 2.
This revealed that the input factors such as immersion time, and extract concentration have a significant effect on the corrosion rate.
Also, the interaction between each response is dependent on the factors as shown from the three-dimensional plots. 3.
Development of regression models to predict and optimize the composition and the mechanical properties of aluminium bronze alloy.

Consequently, magnetic and dielectric properties of such ferrites can worsen [1].

Crack detection of critical beam structures such as bridges and aircraft wings by vibration monitoring is based on understanding how a crack affects the vibration characteristics of a beam structure.
Introduction Beam-type structures are widely employed in both mechanical equipment and civil facilities in which their reliability is usually critically important.
Except the crack depth, all other different factors are considered for the purpose to include their influence on the model if they have and to eliminate calculation errors by statistic procedures.

Then the mixture solution was placed in a water bath at 85 ℃ under mechanical stirring and simultaneously added concentrated ammonia drop-by-drop to adjust the pH value to 11.
The excellent catalytic degradation properties of N-Fe3C@C catalysts was mainly ascribed two aspects.
The catalytic degradation activity of the N-Fe3C@C-4 catalyst in PMS system would be affected by various factors such as the initial dose of N-Fe3C@C-4 catalyst PMS usage, pH value, and the presence of different anions.
The possible reasons for the deteriorated catalytic properties could be ascribed to the fact that the HCO- 3 anion can not only act as a quencher of SO●- 4 and •OH (Equations (5) and (6)), but also promote the pH value of the catalytic system to alkaline conditions, both of which negatively affecting the TC removal [36,37]. the negative influence of the NO- 3 on the TC removal was attributed to the reduction of the •OH radical in the system (Equation (7)) [38].

One strategy, among others, is to use a very thin 4H-SiC layer bonded onto a mechanical carrier.
Excluding those outliers, vendor A would perform the best in this factor.
But as these poly regions only make up a small part of the wafer, we can still look at the projected yield, as only a few devices would be affected.
Doping performance in average level and uniformity is not affected by the substrate type.
