Given that corrosion is causing considerable financial costs of reconstruction, whether in infrastructure, construction, mechanical engineering or monuments, and it also causes failure and reduces the reliability of the structural components, which can lead to serious consequences of various kinds of property damage to loss of life, it is good to know the atmospheric environment in which the exposed material will be used in order to eliminate the possible economic consequences [2, 3].
The key factors of this standard are temperature, humidity, sulfur dioxide pollution and salinity [4].
On the other hand, the results may be affected by a lower number of measuring stations of SHMU.
An important factor in Eq. 1 is chlorides, but there are only 5 stations measuring this parameter.
The main factors obtained in this standard STN EN ISO 9223 could be based on the dose-response function uncertainty or by measurements of air pollution and climatic data.

Physicochemical Properties of Extracted Chitin and Chitosan.
The CT yield of 17.60% aligns with documented yields ranging from 13% to 26.80% [45-47], which are influenced by factors such as extraction techniques and species variations.
This variability is affected by several factors, such as the species of crustacean, extraction methods and environmental conditions during processing phase.
A lower DA suggests fewer acetyl groups, which enhances solubility and mechanical properties, making chitosan suitable for diverse applications [61].

It is influenced by all kinds of factors as electricity, heat and machinery and surrounding environment, so it makes the performance degradation gradually, and lead to fault finally[1].
There are both slowly faults, mutational faults, and electrical faults and mechanical faults. at the same time there both linear system faults and a nonlinear system faults.
The Principles of Fault Diagnosis on Motor Devices The operation of motor devices is influenced by many factors, as the network voltage, load properties, installation environment and the quality of the product and so on.
It is effective for mechanical damage diagnosis particularly.

The design of pine furniture is not only an art design based on the appearance of the pine timber, but also a technical design of its material properties.
As for the structural design of the pine furniture, it should be took into full consideration pine’s physically mechanical properties and its performance in procession,compared with other commonly-used timbers, it has a feature of more softness, bigger coefficient of shrinkage and swelling, and relatively low target of the mechanical strength; Therefore, pine furniture design can be considered as a solid-wood furniture design of a special wood species.
In addition, the pine timbers in the use of furniture-making are different in properties form each other as a result of the difference of their species, the condition under which they grow, and property-changing handling (such as skim-handling, and drying-handling, etc.), even if they belong to a same family.
Compared with other kinds of limbers, all of the pines share some common properties, while the product design of a certain kind of pine is different from each other.
Pine wood’s characteristic that its texture features are different in the different texture direction of cross-striations, radial, and tangential, etc. can be considered as one of the form-design factors.

The terrible working condition and influence of usage factor caused high failure rate of ball mill.
In addition, tube, as a key part, not only affected by gravity but also affected by the impact of grinding media.
Firstly, structural model or mechanical model which is beneficial to analysis is needed.
Modal analysis belongs to intrinsic property in dynamic analysis.
No matter what the outside load is, intrinsic property which contains modal parameters like intrinsic frequency, mode of vibration and so on is affected by itself.

This document deals with the determination of thermal transmission properties of wood-aluminium window with vacuum glazing.
In 2016, during the Coneco and Racioenergia fairs in Incheba Bratislava, wood-aluminium window manufacturer "Mintal Energy VG" was awarded Gold Plaque 2016 for the application of vacuum glazing, for their excellent thermal insulation and acoustic properties (Fig. 1).
These properties were stated by the manufacturer based on the calculation in Window 7 by Canadian Standard NFRC 100-2010.
The linear transmittance,Yg, is mainly affected by the conductivity of the spacer material.
The Ug value corresponds with the heat flow in the middle of the glazing without affecting of the support pillars.

Copper and magnesium strengthen the alloy matrix and improve the mechanical properties and alloy machinability.
Heat treatment is one of the major factors used to enhance the mechanical properties of heat-treatable Al-Si alloys, through an optimization of both solution and aging heat treatment given to these alloys.
Table 2 Factors and Their Uncoded Levels No.
Eutectic silicon morphology, viz., particle size and shape, plays an important role in determining the mechanical properties of Al-Si alloy castings.
The silicon particles, appearing as coarse, acicular needles under normal cooling conditions, act as crack initiators, lowering the mechanical properties.

They have a good adsorbing and desorbing properties.
There are still a few reports on the effect of optical properties on the humidity detection especially the type of metal oxide that has good electrical properties such as ZnO and TiO2 [6].
They found that the electrical properties of Sn doped is higher compare to the undoped due to the increasing of free electron but through the characterization of humidity sensing properties, the found that by the addition of Sn, the surface structure has become bigger and less in porosity and that also contribute to the low surface volume.
The type of structures depend on different kind of factors such as fabrication methods, types of dopants, types of precursors, types of stabilizers and also other parameters such as temperature and environment.
They found that the sensor has good sensing properties due to the high porosity of the surface which increase the adsorption process.
