In this paper, a theoretical-economic study was carried out based on the operation and construction of different types of equipments that use solar energy to carry out the distillation process. The conclusions drawn from the analysis aimed to determine what is necessary for the optimal design of an experimental distillation module that allows bioethanol with specific features to be obtained, for the area of Tehuantepec in Mexico. This study took the experiments carried out by various authors and extracted information relevant to the selection of the parameters and variables of the proposed distiller according to their efficiency and construction costs.

This article aims to give the reader an overview of the development of nature tourism and its importance for the sustainability of rural and natural areas involving special protection. Once you have seen the end of mass tourism, tourism demand is much more heterogeneous and attends a difference of purposes for which such demand is diversified, representing a particularly important tourism and leisure activities that take place now in natural areas, thus giving rise to different types of leisure and tourism, such as Rural tourism, Ecotourism, Agrotourism, Nature and Adventures tourism, Sports tourism in natural areas, etc. What is important for the sustainability of these areas, that are subject to this type of tourism is getting some positive impacts maintaining sustainability and combating the negative impact, that such activities may have on certain protected areas or special conservation. From this point of view, we believe it is important to develop responsible tourism and committed to environmental conservation and for that the local population must be trained in order to achieve development of the territory without the activities that are the fruit of these typologies tourism and leisure pose a danger. Also, the tourist population must be more aware about what constitutes such practices of leisure and tourism for conservation of the environment and, at the same time, the development of the most depressed areas.

Using a phylogenomic approach, we have identified and subciassified a new family of carotenoid-binding proteins. These proteins have sequence homology to the N-terminal domain （NTD） of the Orange Carotenoid Protein （OCP）, and are referred to as Helical Carotenoid Proteins （HCPs）. These proteins comprise at least nine distinct ciades and are found in diverse organisms, frequently as multiple paralogs representing the distinct ciades. These seem to be out-paralogs maintained from ancient duplications associated with subfunctionalization. All of the HCPs share conservation of the residues for carotenoid binding, and we confirm that carotenoid binding is a fundamental property of HCPso We solved two crystal structures of the Nostoc sp. PCC 7120 HCP1 protein, each binding a different carotenoid, suggesting that the proteins flexibly bind a range of carotenoids. Based on a comprehensive phylogenetic analysis, we propose that one of the HCP subtypes is likely the evolutionary ancestor of the NTD of the OCP, which arose following a domain fusion evenS. However, we predict that the majority of HCPs have functions distinct from the NTD of the OCP. Our results demonstrate that the HCPs are a new family of functionally diverse carotenoid-binding proteins found among ecophysiologically diverse cyanobacteria.
