The Tourist Experience and the Challenges of the Environment

Like any other human activity, without containing intentional elements, tourism, being a consumer of space and tourist resources, participates implicitly in the degradation and the pollution of the environment of the tourist potential, either through the direct pressure of the tourists on the landscape, the flora and the fauna, or on other tourist objectives which can be damaged partially or totally, or through the wrong conception of revaluation and equipment of some areas, points or tourist objectives. The natural environment probably represents the greatest wealth of the Romanian tourism. The protection of the environment is thus crucial for tourism. The tourist experience has demonstrated, in time, that, regardless of the type of tourism people practise, a series of impacts results and they are felt by the society as well as by the natural environment. The development of tourism in a certain area must not affect the social and economic interests of the resident population, nor of the environment, and, most of all, of the natural resources which constitute the main attraction together with the historic and cultural sites.tourism, impact, destination, sustainable development, experience

First principles study of a sodium borosilicate glass-former II: The glass state

We use ab initio simulations to investigate the properties of a sodium borosilicate glass of composition 3Na_2O-B_2O_3-6SiO_2. We find that the broadening of the first peak in the radial distribution functions g_BO(r) and g_BNa(r) is due to the presence of trigonal and tetrahedral boron units as well as to non-bridging oxygen atoms connected to BO_3 units. In agreement with experimental results we find that the [3]B units involve a significant number of non-bridging oxygens whereas the vast majority of [4]B have only bridging oxygens. We determine the three dimensional distribution of the Na atoms around the [3]B and [4]B units and use this information to explain why the sodium atoms associated to the latter share more oxygen atoms with the central boron atoms than the former units. From the distribution of the electrons we calculate the total electronic density of states as well its decomposition into angular momentum contributions. The vibrational density of states shows at high frequencies a band that originates from the motion of the boron atoms. Furthermore we show that the [3]B and [4]B units give rise to well defined features in the spectrum which thus can be used to estimate the concentration of these structural entities. The contribution of [3]B can be decomposed further into symmetric and asymmetric parts that can also be easily identified in the spectrum. We show that certain features in the spectrum can be used to obtain information on the type of atom that is the second nearest neighbor of a boron in the [4]B unit. We calculate the average Born charges on the bridging and non-bridging oxygen atoms and show that these depend linearly on the angle between the two bonds and the distance from the connected cation, respectively. Finally we have calculated the frequency dependence of the dielectric function as well as the absorption spectra.Comment: 18 pages; 16 figure

GLOBALIZATION AND POVERTY IN ROSIA MONTANA

Globalization is a concept that, for the past decades, carried on dreadful fears, as well asgreat expectations. Defined as a process of global intercommunication and interconnection ofeconomical, political, cultural forces and actors, globalization leads to a global network that enablestransnational spread of information, technologies, capital, commodities, structures, cultures and people,representing a major change in the social structure of society. In this context we witness new fears andalso, new hopes considering the state of communities, democracies, freedom and identity. Romaniaentered a transition process from a closed society to a hub in the global network with the dawn ofcommunist era, even though the forces of globalization per se empowered the struggle against thecommunist regime. Rosia Montana, a mining locality in Apuseni Montains, in the context of the debatesover the mining project proposed by Rosia Montana Gold Corporation (RMGC), represents a naturallaboratory of observation for social scientists, gathering the main concerns of modernization: theinteraction between global economic forces and local cultures, the empowerment of local community andcivil society, the tension between economic interest and cultural and environmental preservation. In thiscontext, the study emphasizes the analysis of people`s life standard and expectations in Rosia Montana, inthe context of globalization. Admitting that globalization is a multidimensional concept, ambiguous andambivalent in its consequences, we analyze its possible risks and benefits on the quality of life in RosiaMontana.globalization, objective poverty, subjective poverty, corporate social responsibility, sustainabledevelopment.

ROBUST STABILITY APPLICATION

In this paper it is presented the study of the robust control applied in thermal treatment kilns and is given an example of applying of extremely systems in industry. The technological process has tow main components: the oven wall with incandescent material and heat-treat devices. The differential equation describing the heating devices transfer phenomena, which occurs, by discretisation will obtain the corresponding differential equation. The implicit discretisation scheme used has the advantage of a stable solution.stability, control, thermal treatment, differential equations

New interaction potentials for borate glasses with mixed network formers.

We adapt and apply a recently developed optimization scheme used to obtain effective potentials for aluminosilicate glasses to include the network former boron into the interaction parameter set. As input data for the optimization, we used the radial distribution functions of the liquid at high temperature generated by ab initio molecular dynamics simulations, and density, coordination, and elastic modulus of glass at room temperature from experiments. The new interaction potentials are shown to reliably reproduce the structure, coordination, and mechanical properties over a wide range of compositions for binary alkali borates. Furthermore, the transferability of these new interaction parameters allows mixing to reliably reproduce the properties of various boroaluminate and borosilicate glasses

THE TOURIST PERCEPTION OF THE HOSPITALITY INDUSTRY: ROMANIA VERSUS EUROPEAN UNION

Automatically when we talk about tourism, tourism industry and hospitality industry we refer to the term also increasingly mentioned. Through this work we describe the hotel, restaurant business and other travel related activity services, which since 2008 have been continuously developed and represent a source of benefit to the economy of any country. The paper aims to assess the perception of tourists based on a questionnaire about the quality of hospitality services in Romania compared to European Union countries.hospitality, hotel industry, restoration, perception

First principles study of a sodium borosilicate glass-former I: The liquid state

We use ab initio simulations to study the static and dynamic properties of a sodium borosilicate liquid with composition 3Na_2O-B_2O_3-6SiO_2, i.e. a system that is the basis of many glass-forming materials. In particular we focus on the question how boron is embedded into the local structure of the silicate network liquid. From the partial structure factors we conclude that there is a weak nanoscale phase separation between silicon and boron and that the sodium atoms form channel-like structures as they have been found in previous studies of sodo-silicate glass-formers. Our results for the X-ray and neutron structure factor show that this feature is basically unnoticeable in the former but should be visible in the latter as a small peak at small wave-vectors. At high temperatures we find a high concentration of three-fold coordinated boron atoms which decreases rapidly with decreasing T, whereas the number of four-fold coordinated boron atoms increases. Therefore we conclude that at the experimental glass transition temperature most boron atoms will be four-fold coordinated. We show that the transformation of [3]B into [4]B with decreasing T is not just related to the diminution of non-bridging oxygen atoms as claimed in previous studies, but to a restructuration of the silicate matrix. The diffusion constants of the various elements show an Arrhenius behavior and we find that the one for boron has the same value as the one of oxygen and is significantly larger than the one of silicon. This shows that these two network formers have rather different dynamical properties, a result that is also confirmed from the time dependence of the van Hove functions. Finally we show that the coherent intermediate scattering function for the sodium atoms is very different from the incoherent one and that it tracks the one of the matrix atoms.Comment: 15 pages; 14 figure
