Introduction With the development of light wood frame construction in china, a large number of dimension lumbers were used, the grading and the design values of dimension lumber become the key issues.
For the advantages of full scale specimen test, it replaced the clear wood test to obtaining design specifications in the application of engineering gradually in Japan, Europe etc.
The higher MOE always contribute to a relative higher bending strength in the application and design of actual engineering, but the bending strength is not necessarily proportional to MOE [2].
Materials and Methods Specimens.26 dimension lumbers with different types and sizes of knots as the main defects of Larix gmelinii were selected.

Lock-in carrierography (LIC) [1], an InGaAs-camera-based quantitative dynamic photoluminescence (PL) imaging methodology, has been demonstrated to be capable of all-optical and noncontact evaluation of minority carrier effective lifetime [2,3], I-V characteristics [4-6], solar-cell efficiency [4,6], diffusivity/mobility [7-10], diffusion length [7], and surface recombination velocities (SRV) [10,11] of various electronic materials and devices.
The key variables being evaluated were the wet processing equipment & methods, and the dissolved oxygen (DO) of the de-ionized (DI) water.
Future study in HeLIC imaging of dynamic SRV evolution can be made in at least three fronts: (1) by implementing higher-power lasers, the imaged area can be extended from the present 5×4 cm2 area to the entire wafer in order to achieve truly global real-time characterization; (2) the 1-D assumption (no lateral carrier diffusion) used in the current model was supported by the spread and homogenized laser beams used in the experiments (very large size compared to the carrier diffusion length), however, the carrier density were not strictly 1-D due to inhomogeneous carrier transport and recombination properties indicated by the image contrast of all the quantitative images shown in this paper, so more rigorous theoretical treatment needs to be incorporated [18,19] or developed; and (3) imaging time can be further reduced by introducing waveform engineering [20] such as frequency chirping in order to be able to better accommodate the requirement for industrial fast in-line quality control.

Among them, zinc phosphates as a functional materials are especially interesting for their rich structural chemistry and compositional diversity.
During the experiment, we found that this compound is a new engineered anti-corrosive pigment because it can efficiently enhance the inhibition properties of cathodic delamination front.
Also, the decomposition temperature (415 ℃) of this phosphate is higher than that of zincophosphate (<300 ℃), which is help to improve their thermal stability as a heat resisting material.

This problem is also important for the civil engineering complex.
One of the main building materials for construction is concrete.
This material will remain one of the main structural materials for the near future.

Investigation of Magnetic Field Effects on Fluid Mobility and Enhanced Oil Recovery Optimization Alizade Elnur PhD student, Department of Petroleum Engineering, Azerbaijan State Oil and Industry University, 20 Azadlig Avenue, Baku AZ1010, Azerbaijan, e.alizade.99@gmail.com.
Introduction Enhanced Oil Recovery (EOR) is a vital area of research in petroleum engineering, focused on extracting additional oil that remains after primary and secondary recovery methods.
This configuration enabled accurate control and observation of the correlation between input voltage and magnetic field intensity, offering key insights into the device's operational behavior under varying conditions.
The measured indicators, including pH, total dissolved solids (TDS), hardness, alkalinity, turbidity and concentrations of key ions such as calcium (Ca²⁺), magnesium (Mg²⁺), iron (Fe) and manganese (Mn), are presented in Table 2.

Furthermore, aluminium is a low maintenance material.
According to most, if not all, international standards, one of the key factors to be taken into consideration in the design of windows and doors is the wind loads that would be sustained by these structures [3].

One day, my new friend was going to collect application form for engineering in Bengal Engineering College.
This is a significant development as it offered considerable scope in materials design by synergising different kinds of materials to achieve a spectrum of properties as required for a given engineering application.
The name of the department was accordingly changed to department of metallurgical and materials engineering.
I believe that we should explore these approaches to create new materials for engineering applications.
