A Development Strategy for the Revival of Tourist Hotspots following the COVID-19 Pandemic

The ongoing Covid-19 crisis has hit many sectors and industries in the hardest possible way. Travel and tourism-related activities have not been an exception. We contend that a systemic approach can be developed and implemented in order to trace and certify individuals who do not present an epidemiological risk to other people, and also to manage their close interaction. This could lead to the certification of a large proportion of the population—millions worldwide—as not representing a risk of infection to others. It can justify the implementation of a system that can speed up the reactivation of several economic sectors and industries, protecting jobs and accelerating economic recovery in many countries. People who have been ill with Covid-19 have acquired the corresponding antibodies and, therefore, have immunity to the disease, they could travel freely, thereby helping to reactivate the economy. We will explain in this paper how a number of high-tech tools can be implemented as a crowd control system to identify those who do not represent a risk to others, either because they have acquired immunity or because they can be regarded as not carriers of a communicable disease. We devise a method based on the use of a 3D-diagram that shows the existence of an inverse relation between the number of tests performed and the number of individuals that have contracted the disease. The results of the study suggest that the implementation of a new epidemiological tourist strategy in Cuba can help to reactivate tourist activities in the country while avoiding the creation of new hotbeds of infection for Covid-19

EFFET DE LA DEFORMATION SUR LES MECANISMES DE LA PRECIPITATION DISCONTINUE DANS LE CAS DE L’ALLIAGE Cu-4,6At.-%In THE EFFECT OF DEFORMATION ON THE MECHANISM OF THE DISCONTINUOUS PRECIPITATION IN CASE ALLOY Cu-4,6At.-%In

L’étude de la réaction de précipitation discontinue dans les alliages à base de cuivre a suscité un intérêt considérable et a faitl’objet de nombreuses investigations théoriques et expérimentales. La spécificité de ce travail est la mise en évidence de l’effetde la déformation sur les mécanismes gouvernant la réaction de précipitation discontinue tels que la germination, la croissanceet la coalescence des lamelles.Les résultats obtenus par les différentes techniques d’analyse utilisées dans ce travail sont cohérents entre eux et confirmentplusieurs travaux consacrés à ce domaine.  The study of the discontinuous precipitation reaction in alloys at basis of brass provoke a considerable benefit and done theobjekt of many theorical and experimental investigations. Precised description of this work is to make clear the effect of thedeformation on the mechanism ruling the discontinuous precipitation reaction like the germination, the growth and thecoalescence of thin lamellar. The obtained results by different methods used in this work are coherent between them andconfirm various consacred works in this domain

Contradictions of Urban Cities\u27 Renewals

Članak predstavlja pokušaj evaluacije postojećih teorijskih stanovišta o razvoju gradova i gradskih centara. Usporedba slovenskih i Zapadnih iskustava se na prvi pogled čini neprimjerenom zbog razlika u stupnju razvoja, društvenih uvjeta, kao i nepostojanja odgovarajuće literature u Sloveniji. Usprkos tome moguće je ustanoviti neke sličnosti u strukturi procesa obnove gradskih jezgara, pa i sličnost interesa društvenih grupa koji se ostvaruju tokom obnove. Samo u okviru takve analize interesa i rezultata njihovih utjecaja moguće je praviti usporedbe, bez obzira na specifičnosti problema različitih gradova, kao i razlike u organizaciji odlučivanja koju definira osobenost društvenog sistema. Dosadašnja iskustva alternativnih razvojnih oblika gradskih centara upozoravaju na slabosti pri rješavanju socijalnih problema i istovremeno usmjeravaju pažnju na socijalna i ekonomska pitanja.The study represents an attempt of evaluation of existing theoretical views on the city development. The comparison between Slovenian and western experiences is particularly delicate, since there is a gap in the level of development in social circumstances and written materials available. But it is possible to notice some similarities in the structure of the renewal process and similar interests of social groups which are taking part in urban renewal actions. It is only within such a social interest analysis that we are able to make comparisons, neglecting the differences and particularities of each urban case and possible differentiation of the decision making process — defined by different social organization of the system
