Organic coatings are widely employed in the corrosion protection of most metal surfaces, particularly steel. They provide a barrier against corrosive species present in the environment, due to their high resistance to oxygen, water and ions transport. This study focuses on the evaluation of corrosion protection performance of epoxy paint on the carbon steel surface in chloride environment (3% NaCl) by Electrochemical Impedance Spectroscopy (EIS). The electrochemical behavior of painted surface was estimated by EIS parameters that contained paint film resistance, paint film capacitance and double layer capacitance. On the basis of calculation using EIS spectrums it was observed that pore resistance (Rpore) decreased with the appearance of doubled layer capacitance (Cdl) due to the electrolyte penetration through the film. This was further confirmed by the decrease of diffusion resistance (Rd) which was also the indicator of the deterioration of paint film protectiveness. Microscopic analyses have shown that oxidation dominates the corroded surfaces.

Recently construction companies and real state of SMEs sector of Dubai, reported that they have a combine shortfall of skilled staff of up to 500,000.  In addition to that, recently tourism industry of UAE, one of the most dominating service sectors also reported the severe shortage of qualified hospitality staffs. The shortage of workforce in the industry is one of the major causes of unfair distribution of work load and also an unjust compensation and reward system in the overall industry.  The supply and demand of workforces is also one of the crucial predictor factors for job satisfaction and may lead to quit their job or to migration.While examining the various factors that may affect employee’s intention to leave, many research findings confirmed that job satisfaction caused the highest variance on to leaving intention.  To get the deeper analysis of the job satisfaction and its impact on employee’s intention to leave, many researchers argued that there were many facets of job satisfaction that may cause the leaving intentions and therefore job satisfaction has been considered a variables composed of multiple factors. It is evident that there are many studies had been conducted to examine the relationship between job satisfaction and employees leaving intentions. However, not many studies on the same line have been fully addressed in small and medium size firms in UAE working setting and also most of the studies sampling strategies had focused in industries in developed economies.  Therefore, it is believed to be a gap in the literature in the context of the job satisfaction and intent to leave in SMEs.

Abstract The article studies the existence experience of historical cities as centers of tourism development as in the case of Elabuga. The city of Elabuga is among the historical cities of Russia. The major role in the development of the city as a tourist center is played by the Elabuga State Historical-Architectural and Art Museum-Reserve. The object of the research in the article is Elabuga as a medium-size historical city. The subject of the research is the activity of the museum-reserve which contributes to the preservation and development of the historical look of Elabuga and increases its attractiveness to tourists. The tourism attractiveness of Elabuga is obtained primarily through the presence of the perfectly preserved historical center of the city with the blocks of integral buildings of the 19th century. The Elabuga State Historical-Architectural and Art Museum-Reserve, which emerged in 1989, is currently an object of historical and cultural heritage of federal importance. Museum-reserves with their significant territories and rich historical, cultural and natural heritage have unique resources for the implementation of large partnership projects. Such projects are not only aimed at attracting a wide range of tourists, but also stimulate interest in the reserve from the business elite, municipal and regional authorities. The most famous example is the Spasskaya Fair which revived in 2008 in Elabuga. It was held in the city since the second half of the 19th century, and was widely known throughout Russia. The process of the revival and successful development of the fair can be viewed as the creation of a special tourist event contributing to the formation of new and currently important tourism products.
