The degradation of wood in outdoor conditions is mainly a surface process and it is caused by factors such as solar radiation, moisture, temperature, dust and other physical and biological agents [1, 3] as a result primarily color changes and mechanical damages occur.
Investigation of changes in wood during weathering is important for finding of new more efficient treatment solutions that ensure the required stability of the decorative properties.
In this study the artificial weathering test was carried out to evaluate and select the processing parameters which could enhance the service properties of the final product.
The only parameters which can affect the absorbed amount of paint are, at a fixed temperature, the dipping time, the viscosity and the composition of the paint and the morphological properties of the wood surface.

Ferroelectric properties of the lead-free ceramic behaved a coercive field of 12.5kV/cm and remanent polarization as high as 30uC/cm2.
That is why it could have potential to behave good piezoelectric properties.
The formation of secondary phase which affects the electrical properties a lot was found to be one of the key issues for dopants in lead-free ceramics.
To achieve improved ferroelectric properties, it should be important to reduce the formation of secondary phase.

Light weight as a primary factor in combination with strength and durability properties of aluminium alloys brings financial benefits accruing not only from material procurement but along the whole chain of production, manufacturing, delivery and installation, maintenance and even disposal.
Material and Structure Light weight as a primary factor in combination with strength and durability properties of aluminium alloys brings financial benefits accruing not only from material procurement but along the whole chain of production, fabrication, delivery and installation, maintenance and even disposal.
Mechanical and physical properties influence thus performance: · Material specific weight is one third that of steel, strength is comparable to typical steel; the main load-carrying structure of an aluminium footbridge will exhibit 50% or less of the weight in steel [1].

Introduction Among the various non-conventional machining methods Electro-Discharge Machining (EDM) is the most widely and successfully applied for high precision processing of various conductive materials regardless of their mechanical properties [1].
The resulting surface texture seriously affects product quality and applications [1, 4].
The pulse energy is calculated by the formula: We = Ve Ie tp (Ve = 30 V) whilst Ie and tp were taken into account as design factors in the factorial design.
In particular, as obtained by the sum of squares of the factors (fourth column of Table 1), Ie presents its highest statistical and physical significance on Rt and Ry.
As mentioned earlier Ra increases when both factors increase in the range considered in this study and especially for Ie which proved to be the most significant factor over the response variables; see also similar comments in [5, 8].

Investigation of the Influence of Technological Regimes of High-Temperature Firing on the Structure and Properties of Silicate-Enamel Coatings for Carbon Steels А.V.

With the constantly increasing requirements for the technical and operational properties of enameled products in the production of steel pipelines, it is advisable to use single-layer enameling, which saves raw materials and energy, due to the reduction in the number of layers and firing cycles of products.
The purpose of these studies was to study the influence of technological regimes of high-temperature firing on the structure and properties of silicate-enamel coatings.
