It has been suggested that the stretch properties of fabric can be relied upon too heavily, rather than utilising pattern shapes that are suited to the design[20, 21].
As a fabric is stretched and heads towards the maximum strain, the stretch properties of the fabric are exhausted, and the fabric begins to feel stiff.
This factor was accounted for in the active ROM joint angles, the S&R, and TU&G tests by comparing suited results to a baseline of gym clothing, however, this could still affect the psychological discomfort and mobility ratings.
Further investigation is required to separate the effecting factors.

ACPs have variable chemical but rather identical glass-like physicochemical properties.
Furthermore, to be used in surgery, all implantable 3D constructions must possess the necessary mechanical properties, which is difficult to achieve in the case of ACPs.
For example, both dense blocks and porous scaffolds made of calcium orthophosphates reach their mechanical properties only after sintering at temperatures, exceeding ~ 1000 °C, which is impossible in the case of ACPs (see “Thermal properties” section above).
Amorphous calcium phosphates: synthesis, properties and uses in biomaterials.
Existing calcium orthophosphates and their major properties [26, 27].

Some prominent medical biomaterials potentially produced in fulfilling those superior properties from sericulture are inorganic-organic hybrid biomaterials.
Silk fibers containing mainly two parts, sericin and fibroin, have important properties as medicinal biomaterials.
Moreover, the root extract of mulberry Morus alba L was reported having therapeutic potential as a hair loss preventative because of its ability to stimulate the secretion of pro-proliferative and pro-angiogenic paracrine factors from human dermal fibroblasts [45].
Profiling of silk sericin from cocoons of three southern African wild silk moths with a focus on their antimicrobial and antioxidant properties.
Synthesis and microstructural properties of the scaffold based on a 3-(trimethoxysilyl) propyl methacrylate–POSS hybrid towards potential tissue engineering applications.

In the process of desulfurization, the accurate detection of SO2 concentration is a key factor.
Non-dispersive refers to that continuous light irradiates the sample all and the sample has selective absorption and integration property.
Added mechanical chopper and IR-CUT filter after light source; adopted catadioptric gas cell and thermoelectric release detector.
The light source emitted light, and the light was modulated by mechanical chopper and filtered by bandwidth filter, then it was modulated by gas filter correlation wheel, at last it went into gas cell.
It’s necessary to choose a 5v stabilized source to supply for the Nernst lamp, because its characteristics affected by temperature.

Piezoelectric transducers have been widely used in various smart structures and mechanical
systems [1, 2].
The physical properties of the steel beam were mm1 203002 ××=×× syx hLL and the thickness of the PVDF sensor was m52µ=peh , and the constant k in Eq. (3) is 1/15.
Lee and Moon [3] showed the response of piezo sensors was sensitive to small errors in the shapes of the transducers, particularly affecting the high frequency response.
(9) where )(ωnB , )(xnφ , onω , sρ , sA and sη are the harmonic modal amplitude, mode shape, natural frequency, density, sectional area, and loss factor of the beam.
The position sensor was designed based on the electromechanical property of the piezoelectric transducers piezoelectric to generate charge output proportional to the tip displacement of a cantilever beam when the beam is subject to purely flexural motion.

On the 17-inch screen, the enlargement factor of the image is about 300.
Fig. 4 The schematic diagram of block electrode discharge grinding Fig. 5 Microelectrodes ground by BEDG Theoretical of Machining Gap When machining holes with cylindrical electrode, the real gap between the electrode surface and the hole wall is the sum of the breakdown gap, the depth of discharge crater and the gap caused by other factors.
The gap caused by other factors is expressed by Hm.
So Hm is not a key factor.

Friction Stir Processing (FSP) has potential for locally enhancing the properties of Al-Si
alloy castings, for demanding applications within the automotive industry, by greatly refining the
second phase particle size.
By refining the microstructure of cast Al-Si alloys, the high temperature mechanical performance and, in particular, fatigue properties should be improved [1,4,5].
By subjecting Al-Si alloys to FSP, the tensile and fatigue properties have also been found to improve [6-9].
At high speeds the shoulder affects the material to a much shallower depth and the PZ profile on the retreating side becomes much closer to the tool.
Providing a sufficient strain is reached, the dominating factor controlling the particle size appears to be the temperature and corresponding matrix flow stress within the shear layer at the tool surface.

Huang Dongming (2007) et al. represented a model of cone crusher productivity which is affected key design parameters(oscillating speed, closed size setting, base angle of cone, eccentric angle)[10].
Particle size distribution is an important economic and technical performance indicator of cone crusher, and it will affect the economic benefits of the user.
However, it is diffi{TTP}-1279 cult to measure product properties in real time at a plant due to several factors, e.g. the high capacities, the dirty environment, and the wide range of product sizes.
