In post-modern era, appearance is a beloved factor due to appearance is general a bearer of culture.
In the background of highlighting national culture, product design should be realize the harmony of many factors such as material and spirit, and respect human freedom.
But it limits the people's imagination and working space, and causes many occupational disease, such as computers disorders, cervical spondylopathy, and so on, which all affected our work and life.
Since it first subversion original rigorous inflexible appearance of the personal computer, and give a great temptation and impact to consumers: a cold mechanical shows its lively side, and make greatly publicize the personalization, emotional of the products, Since then, dares to express their feelings, and the design of pursuing vogue style such as tide surging.
We should deal with the relation between design and the environment, because in order to meet the demand of changing aesthetic, sometimes design will shorten the life cycle of product, and causing the resource waste, and the non-functional design may have the affect of coordination.

Abstract.
This last factor is a crucial argument for ship owners and shipping management companies [3].
The newly designed grinding device is a mobile, electro-mechanical instrument, the principal construction of which is relatively simple and safe.
Given the successful results of the newly developed grinding device, its precise impact on the ground surface properties also had to be investigated.
Multifactorial analysis was carried out by splicing input factors and comparing them with the combined outcome results.

They have outstanding properties like harder, high thermal conductivity, low thermal expansion and high cutting capacity.
The distribution of the normal and shear stresses have maxima in the region adjacent to the cutting edge, and become zero at the end of the contact, which depend on the mechanical properties of work material and cutting conditions.
And it is believed that the greatest influence on the contact conditions at the tool-chip interface is its thermoconductivity and adhesion properties[2].
The fatigue life is influenced by a variety of factors, such as the stress state, surface quality, material type, environment, temperature, crack closure, etc.

Therefore, heat resistance, flame resistance and mechanical property etc. are essential to fire fighter protective clothing.
The moisture in clothes is one of the factor of heat stress.
The upper-layer has heat resistance, flame resistance and mechanical strength.
The innermost layer is textile having heat insulation property.
It came out that the fire fighter protective clothing is the main factor which control heat loss.

The study of the acoustical properties of a mosque have largely been neglected and have not received as much attention in the literature when compared to other places of worship such as churches [1,2].
The measurements were carried out when the main prayer hall was relatively empty and the constant climate temperature at 27oC were assumed not affecting the values.
The modulation reduction factor is calculated at each octave bands of 250 Hz, 500 Hz, 1000 Hz, 2000 Hz and 4000 Hz.

The scale of any nature affects the thermal conductivity of the system and reduces cooling efficiency [2].
The causes of corrosion of the metal elements of the NPP cooling system can be completely different factors, in particular, corrosion cracking under the influence of the environment, under the influence of voltage and radiation, the force of water flow, as well as under microbiological influence [6].
When applying biocides, preference is given to highly effective reagents that do not have a corrosive effect and lose their toxic properties within a short time [26].
The bench tests confirm the possibility of using NaClO and DBNPA biocides without affecting the corrosion resistance of the structural materials of the SCS Rivne NPP and the natural safety when they are discharged with cooling water into the Styr River.

Abstract.
Introduction Giant magnetostrictive materials convert magnetic energy in to mechanical energy and vice versa.
In addition to this the hysteresis and non-linearity are the two key factors mainly restrict the properties of Terfenol-D in most of the application due to inherent characteristics of all giant magnetostrictive materials.
The total magnetization equals to or (5) Magnetization for dc input: experimental output and theoretical predictions Magnetization curves are obtained by solving magnetization equation for different identified values of which affect the magnetization curve using Jiles-Atherton model under dc input.

Their mechanical and structural properties are similar to those of extra-cellular matrices (ECM) [10].
The mechanical vibration of ultrasonication can cause formation and collapse of bubbles that could bring local effects: heating (10,000 K), high pressure (200 bars) and high strain rates (107 s–1) [16, 17].
These physical factors can accelerate interaction of the SF initial molecule chain and promote formation of the physical cross-links that are responsible for hydrogel stabilization.
The early studies of B. mori SF [4,5,19,20–22] indicated that the two original samples that were not affected by ultrasonication consist mainly of β sheet.
