Investigations on its stiffness and hysteresis properties [2], roll-over shape [3–5], energy storage and return [6,7], dynamic behaviour [8], kinematics and kinetics [9–13] have been performed.
Evaluation of geometry and material properties: The inputs for the FEA included geometric and material properties of the SACH foot.
The shear modulus and the incompressibility factor for the model were evaluated from the uniaxial tensile and volumetric compression tests, respectively.
Hence, the modulus of the components that might affect the forefoot stiffness, in this case, the cosmetic foam and the pad, were improved in the first iteration of the design.
Stiffness and hysteresis properties of some prosthetic feet.

This research could be valuable for the development of application to edible coating and MAP for improving the shelf - life properties of sweet persimmons.
The most common browning reactions in fruits are resulting from enzymatically catalyzed reactions, mainly by PPO (EC 1.14.18.1) in the presence of oxygen[1] especially the fruits with mechanical wound.
Naphthylacetate is one kind of plant growth regulators, which affects polyamine levels within the organization probably by controlling polyamine synthetic enzyme activity[4], thus slowing down the aging of fruits.
(a) PPO activity and (b) MDAcontent of sweet persimmons during storage at - 0.3 ~ 0 °C PPO activity PPO is considered one major factor involved in enzymatic browning which generally results from the oxidation of phenolic substrates and brings about drop of sensory quality.

The physical properties of working fluids at 25oC are shown in Table 1.
From the above analysis, it should be noted that for the similar shapes from top view, the shape from side view could also be different due to the difference in wetting properties.
Note that Fig.2d only shows the possible droplet shapes in static conditions, the actual droplet shape is hard to determine due to the comprehensive influences of wetting properties and viscous drag by fluid flow.
For instance, the flow velocity affects the advancing and receding contact angle, leading to different droplet shapes compared with the static conditions (see Fig.2e).
The droplet shape could be spherical, hemispherical, flattened disk and plug, depending on the specific wetting properties and flow conditions.

However, the double aging heat leads to a very high improvement of mechanical properties [9].

A Case Study on a Fire Disaster in a Textile Factory Cherngshing Lina, Mingen Wub, Shengmin Tsaic Department of Mechanical Engineering Yuan Ze University, Taoyuan 32003 Taiwan, R.O.C.
Factory fires typically cause substantial casualties and property losses, and have therefore become a focal point for research.
Findings have shown that escapee response time, walking time, and waiting time are the three fundamental factors influencing overall evacuation time.
Therefore, the materials stacked at the bottom were unaffected or partially affected by the fire.

Introduction Dual-phase (DP) steels belong to the family of advanced high strength steels (AHSS) that exhibit novel mechanical properties such as increased tensile strength with improved ductility (hence formability) as compared to conventional HSLA steels [1].
These models are based on the concept of microstructure engineering where the operational parameters of a mill are quantitatively linked to the final microstructure and mechanical properties of hot band.
Volumetric grain sizes were obtained by multiplying the measured EQAD with a factor of 1.2 [5]. 3.
In the present study of continuous cooling transformation, the carbon redistribution during ferrite transformation which in turn stabilizes the un-transformed austenite due to its carbon enrichment, is considered to affect the transformation kinetics.

So far, porous phenolic composites are receiving more and more attention in the aerospace, defense and the high-tech fields due to their lower density, high damping property and electromagnetic shielding ability, etc.
In fact, damage at any instant exercises a significant influence on the mechanical properties of materials.
Before the appearance of macro-level fracture, the microscopic damage already affects the material stress and strain relationship especially near the crack tip.
Suppose that there are m voids in material at time t, let denote the nucleation density (the number of newly-increased void due to nucleation in unit volume of solid per unit time) and be the void volume at the minimum nucleation, one can obtain the following expression of : (6) By assuming the inertia effects are negligible, the growth rate of void can be obtained based on the phenomenological point of view, i.e., [5]: (7) where is the characteristic factor of void growth, denotes the tensile stress, is the threshold stress at damage, andis a damage dependent exponent.
Spall simulation for porous phenolic composites Research studies have shown that phenolic composites exhibit some special properties as stated above.

A centrifugal force seriously affects the clamping force when the rotational speed exceeds 1 000 000 rpm [5], so it was ignored here.

The development of Standards and Legislation of Heat Technology in the Czech Republic Thermal-technical parameters of building envelopes affect not only the energy requirements of the building, but also a thermal comfort and indoor environment, as well as ultimately contribute to an efficient energy management.
Temperature requirements of internal surfaces of structures using the temperature factor of the internal surface are evaluated.
These trends are reflected in the requirements for even greater energy savings in the design of larger thickness of thermal insulation, better heat insulation properties of thermal insulators, greater mechanical strength, intensity and color fastness, resistance to biological pest control, etc.
