The results showed that the eccentricity ratios and slenderness ratios are the primary factors to influence the load-bearing capacity of CFSST columns, with the increase of eccentricity ratios and slenderness ratios, the limit load-bearing capacity reduced gradually.
Material Properties.
It can be found that, slenderness ratios have big influence on specimen elastic stiffness, and they do affect the load-bearing capacity and ductility of the columns to some extent.
The eccentricity ratios and slenderness ratios are the primary factors to influence the load-bearing capacity of composite columns, with the increase of eccentricity ratios and slenderness ratios, the limit load capacity reduced gradually. 3.

In earlier studies, starch matrix thickness increased up to 2.5mm, showed improved mechanical properties, promote water retention causes enough time for the molecules to relax and orient [1].
To reach starch concentration, values were multiplied with factor 0.9.
Addition of lignin have been associated with reducing water uptake [5] and increasing the mechanical properties [6] in the lignin treated starch matrix.

Reprocessability Index (RPI) is a metric that determines the mechanical properties of a component through design, product re-factor reliability, and suitability size.
RPI imparts a sense of how the physical properties of the material can be used to conserve resources and protect the natural environment [4].
Details related to the volume and natures of the components are the most significant factors that influence reuse of components.

As the welding of stainless steel and copper belongs to dissimilar metal welding and their physical properties are very different, thus the welding of them is difficult and it is likely to cause a variety of defects in the welding process.
Through preliminary simulation and access to relevant Fig. 1 FE model of connecting pipe Fig. 2 Meshing of welding seam and heat affecting zones information, the heat affected zones of two tubes are all 3mm wide.
But for the welding of dissimilar metal, even though the weldments are symmetrical about the welding seam, the temperature distribution is asymmetrical as a result of the difference of physical properties of each weldment.

Introduction Composite materials are widely used in aviation and aerospace because of their excellent properties such as high strength weight ratio, high stiffness to weight ratio, low density, corrosion and fatigue resistance, and designable features.
Mechanical linkage has good debonding resistance with no curing residual stress, and it is hardly affected by environmental factors.
But mechanical linkage can increase the weight of structures and may affect the streamlined external shape of airplane.
Mechanical linkage is usually used on thick structure assembly.
This method has some excellent properties such as good debonding resistance, low equipment requirements and good structure strength recovery.

The CO2 emission factors of each tree species are significantly higher than other gases.
Emission factors of different tree species.
And CO2, CO and CxHy (total of CH4) emission factors (2.9624 g • kg-1, 0.4261 g • kg-1, 0.0126 g • kg-1) that they measured were similar with the three kinds of carbon gas emission factors in this paper.
The main reasons were their different physical and chemical properties and different C content, resulting in a variety of amount of different trace gases released in combustion reaction.

The input factors considered were contact time, temperature and fan speed while the response (output) chosen was the residual moisture content of the seeds.
The results obtained revealed that temperature, contact time and fan speed were affecting the drying of the seeds.
Factors affecting drying include vapour pressure, temperature, relative humidity, air circulation, nature of wet feed, the way it is introduced into the dryer and a host of other environmental factors [9].
For domestic purposes, Moringa oleifera leaf powder has been found to be effective as soap for hand washing when wetted in advance to enable antiseptic and detergent properties from phytochemicals in the leaves [17] to be active.
Also found from the results of this research was that temperature, contact time and fan speed were important parameters affecting drying of moringa seeds.

Introduction The mechanical behavior of cells has been shown to affect cell adhesion, growth, differentiation [[] D.E.
For these cells to adhere, mechanical forces must be present.
In the model, the substrate properties are chosen such that they match the properties of the polyacrylamide gels that are used as substrates in the experiments: the substrate is modeled with linear elastic 8-node bricks with Young’s modulus of 7.1 kPa and Poisson’s ratio of 0.48.
Contact inhibition and scattering have been shown to have chemical cues such as growth factors [[] J.H.
We are currently studying this hypothesis by investigating how cells respond to mechanical cues such as substrates of different stiffness and to chemical cues such as epidermal growth factor.

Contamination can change the physical properties of soil, reduce the strength of cemented soil foundation, and then induce the instability or disruption of buildings.
Contamination from municipal sewage can change the properties of soil, affect the unconfined compression strength of cemented soil, and then induce the instability or disruption of buildings.
