The choice of the strengthening solution to be adopted for improving the in-plane capacity of a masonry panel is governed by several factors.
Mechanical anchors conventionally used consist of L-shaped steel rods with diameter up to 6mm.
However, also in this case, mechanical anchors are needed to connect the pre-formed fiber grid to the masonry panels.
The strengthening configuration can strongly affect the effectiveness of the intervention.
The main properties of experimental tests, such as the reference, the specimens’ labels, the strengthening configuration, the panel dimensions (t=thickness and L(H)=edge length), the matrix thickness, the grid material and spacing and the experimental peak shear stress τmax are summarized in Table 1.

Our findings further demonstrate that the change in the collagen network topography at the nanoscale level affected differently cellular morphology of HepG2 and primary human umbilical vascular endothelial (HUVEC) cells through alteration of the cell-cell and cell-ECM interactions in a cell type-dependent manner.
This basal medium was preliminary supplemented with the “Endothelial Cell-Growth” kit (ATCC® Global Bio-resource CenterTM) in order to create a complete and low serum culture environment which offer an optimal cell proliferation rate because of several purified human recombinant growth factors including rhVEGF (5 ng/ml), rh EGF (5 ng/ml), rh basic FGF (5 ng/ml), rh IGF-1 (15 ng/ml), L-glutamine (10 mM), heparan sulfate (0.75 U/ml), hydrocortisone (1 mg/ml), ascorbic acid (50 mg/ml) and FBS (2%).
Integrins physically connect the Arg-Gly-Asp (RGD) sequence of ECM components to the cell cytoskeleton and are involved in the transmission of mechanical signals through this molecular bridge, affecting mechanical forces within the cell that shape cell morphology.
Influence of substratum surface properties on the organization of adsorbed collagen films: in situ characterization by atomic force microscopy.
Progression of HCC in mice is associated with a downregulation in the expression of hepatocyte nuclear factors.

The compositions of these hydrogels, their physical and mechanical properties are not given, the information is promotional.
Such properties, in our opinion, will allow using it as a basis, at creation of water fire extinguishing substances with the increased adhesive properties and the increased factor of use of water.

Therefore, clad metals, consisting of two or more metals, have been developed due to their unique properties.
Although the physical and chemical properties of Copper and Aluminum are different, they are complementary to each other.
Comprehensive consideration of factors such as bond strength, the surface quality; the optimal deformation rate should be controlled at 60%~65% [3].
This shows that the addition of Silicon plays a key role in guaranteeing the high temperature properties.
At the meanwhile, it ensured the high temperature properties.

The corrosion resistance and mechanical strength can be improved by proper addition of alloying elements [2].
Microstructure is a key factor for the corrosion behavior of cast magnesium alloys.
Characteristics such as morphology and volume fraction have a strong influence on the corrosion properties of the alloy, being affected by specific heat treatments [6].
The fraction of Mn-rich precipitates was not significantly affected by the heat treatments whereas the b-phase was severely affected.
The cathodic branches almost coincide for all the curves, suggesting that the cathodic reactions are not affected by the heat treatments.

In Al-6%Cu base ternary systems, zinc addition
improved the sintered properties to some extent but the heat treated properties more significantly.
In this regard, the characters and the amount of the liquid phase formed during the sintering are most critical factors for improving the sintered properties.
Temperature and time for solutionizing and aging are the critical factors determining the heat treated properties.
Table 3 summarizes the mechanical properties and the sliding wear resistance of some selected AlCu-Zn blends after the heat treatment.
(4) The zinc addition affected the heat treated properties much more than the sintered ones, presumably due to more precipitation in the matrix.

Due to the complexity and indeterminacy of the engineering geological characters, the design theories and analysis methods can't entirely consider the factors of influence on settlement of comprehensive pipe at the same time, such as complex formations, support rigidity and change of groundwater and so on[3].
The measured settlement data obtained on the site could mainly represent the effect on factors.
According to soil tests table of the geological investigation report, the mechanical parameters of the backfill get from the measured value of soil tests in laboratory.
The selection and how to deal with of boundary conditions of numerical simulation can affect results greatly.

The creep properties of FGH96 superalloy were studied in the temperature range of 650 °C to 750 °C and stress range of 690MPa to 897MPa.
FGH96 superalloy was one of the most widely used PM superalloy in aero turbine due to its excellent tensile and creep properties [1~3].
Therefore, it was a key factor to obtain the accurate value of the Helmholtz free energy and the activation volume which could affect the accuracy of creep strain rate prediction.
The effects of stress and temperature on creep properties were investigated to find the comfort zone for the creep property in FGH96 superalloy.
