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.

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.

Average degree of polymerization of insulation oil paper (board) material used in large power transformer is generally about 1000, when the toughness and strength and mechanical strength of insulating paper (board) are good.
The degree of polymerization, the number of glucose monomers constituting the paper fibres, closely related to the mechanical properties of the insulating paper, is the most reliable characteristic parameters reflecting the ageing condition of the insulating paper.
The latter one describes that of the transformer internal temperature distribution and the different hot spots, will directly affect the solid insulation ageing rate.
Table 3 gives the remaining life assessment results with a sole factor of temperature.
The oil temperature has substantially reduced after the main transformer cooling transformation, so if the temperature factor is only taken into account in the transformer thermal aging analysis, the life assessment results obtained will be a longer life expectancy, and this results are not in line with the actual situation of the joint multi-factor aging.

Other studies associated with the effect of temperature on corrosion process of carbon steel in contact with saline soils and solutions representative of soils suggest that the effect of depth and type of soil are relevant factors to activate the oxidation of steel [11-13].
Soil properties depend of soil particle size distribution, organic content, mineralogical composition and structure.
The above is due to the different physico-chemical properties and biological effects of each one of the soils such as particle size, organic matter content, water-retaining capacity, and mainly ionic conductivity of each soil.
As it is shown in Table 3, the conductive properties of each soil are as a follow: marshy soil > clay soil > sandy soil.

(2) The denominator of Equ.(2) is independent of the window length chosen, but the numerator is affected by it.
It is thought that the SK has a number of properties that will make it very useful in the area of prognostics, but these have not yet been fully exploited.

The angle g is auxiliary and does not affect the shape of the curve in any way, however, to increase the robot’s reach, a gradual increase in the angle of the grip rotation and the extension of the hand with the end tool as far from the base as possible is used
The designed precast multi-functional concrete mixture is characterized by good workability and rapid evolution of mechanical properties as well as satisfactory long-term stability of hardened composite.
Protective eye goggles and a respirator with a protection factor against products of combustion and smoke are recommended for personal protection Fig. 7 Working surface must be consolidated and be waterproof and inactive to acetone-based chemical substances.

The morphology of rape seeds and powdery fractions The dust formed during the handling of rapeseed meal differs in chemical composition and physical properties comparing to the natural meal, due to the morphology of rapeseed.
Hull has in relation to the cotyledon and embryo less fat (6% vs 56% dm) and protein (15% vs 44% ddm), but more fibers having the encrusting properties (40% vs 6.6% ddm) [5].

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.

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.

The thermophysical and electrical properties of the TECs, insulation material, Aluminum plates, and the flowing fluids are shown in table (1).
Table 1 Thermophysical and Electrical Properties of all Materials and Fluids used in the current study [4, 14, 17,18, and 19].
The presented numerical model was solved under assumptions shown below regarding the TEC model: - 1- The flow is incompressible and unsteady. 2- The thermoelectric properties of the TEC are constants.
COP factor was chosen as it represents a dimensionless factor in which mor than one variable is included.
The primary air inlet temperature was chosen to be (319 oK) and the flow consider to be incompressible and the thermoelectric properties of the TEC are constants while the Seebeck effect and conductivity effect are neglected in the connector and load surfaces.
