Rural tourism destination competitiveness: Portugal vs Belarus

This research presents a study aimed to evaluate the performance and competitiveness of tourist destinations in Portugal and Belarus within regions. The evaluation was performed under an analytical tool, Market Share Analysis proposed by Faulkner (1997). In addition, it was used some descriptive statistics. The conducted analysis concluded, with respect to the evolution of the destinations tourism that Açores Island is the most prosperous market for the majority of countries, because most countries staid in the zone of Performing market. North, Lisbon and Algarve regions are maturity markets for the most countries, because they stay in Stagnant markets zone. Centre and Alentejo regions could be attributed Emerging markets for the majority of countries once are developing markets. The major market share is occupied by Portugal practically for all regions, except islands. It is also necessary to underline, that the research was made only within two years (2013 and 2014), because of the lack of necessary information in previous years. In the case of Belarus, it could be mentioned, that rural market of this country is developing (but still mostly with neighbour countries), because the number of entities, participating in rural tourism is growing as the number of foreign tourists.

Effect of different feed-rate in bone drilling: experimental and numerical study

The behaviour of bone tissue during drilling has been subject of recent studies due to its great importance. Because of thermal nature of the bone drilling, high temperatures and thermal mechanical stresses are developed during drilling that affect the process quality. However, there is still a lack information with regard to the distribution of mechanical and thermal stresses during bone drilling. The present paper describes a sequentially coupled thermal-stress analysis to assess the mechanical and thermal stress distribution during bone drilling. A three-dimensional thermo-mechanical model was developed using the ANSYS/LSDYNA finite element code under different drilling conditions. The model incorporates the dynamic characteristics of drilling process, as well as the thermo-mechanical properties of the involved materials. Experimental tests with polyurethane foam materials were also carried out. It was concluded that the use of higher feed-rates lead to a decrease of normal stresses and strains in the foam materials. The experimental and numerical results were compared and showed good agreement. The proposed numerical model could be used to predict the better drilling parameters and minimize the bone injuries.
