Chlorhexidine and fluor are treatment which have been used to prevent dental plaque formation and, subsequently, dental cavities. The objective of this study was to identify the effectivity of chlorhexidine in varnish to prevent dental plaque formation. A quantitative test was carried out, comparative-descriptive, transversal and observational. The sample observed was integrated by 13 children from 6 to 10 years old, to whom, a questionnaire about fermentable carbohydrates consumption was applied; they were identified to have dental plaque, registering it through the O’Leary index. Later, they were divided into two groups, the first group was applied fluor varnish at 0.1%, and the second group was applied chlorhexidine varnish at 1% with Thymol at 1% as a homogenous mixture. Four weeks later, second dental plaque identification was executed and registered in the same initial way. The data was analyzed stablishing an average, standard deviation and Pearson correlation coefficient. The results obtained indicate that there is a weak negative correlation (-0.13) between the O’Leary index and fermentable carbohydrates consumption, a weak negative correlation (-0.065) when correlating the O’Leary index obtained after fluor application and fermentable carbohydrate consumption; as well as a weak positive correlation (0.084) when correlating the O’Leary index obtained after chlorhexidine application and fermentable carbohydrate consumption. It is concluded that, in order to determine the effectiveness of this drug, it is necessary to augment the sample size, and deeper studies must be done having into consideration other factors not analyzed in this investigation since, apparently, chlorhexidine usage is not enough to impact positively on the presence of dental plaque and caries.

As part of the communicative processes that transform and establish the social dynamics, the confidence forms a part fundamentally of the foundations that determine attitudes towards institutions, groups or organizations.This article aims to analize the confidence shown by fans of the Olmec baseball team in Tabasco, which determines the relationship and behavior that exists among baseball fans in relation to the results obtained in the last season through an analysis using the theory of social representations as a basic premise for their development. To establish confidence index, the oficial page of the team was tracked and a five-items questionnaire was built between 100 attendees at the last of the games, revealing that the team´s follow-up is generated primarily by aspects of identity, with a lesser influence of the opinions expressed in the media and based on previous results, where this team has not achieved triumphs for 25 years.

The present document analyses the mexican identity in furniture design. In this explorative investigation the authors did a referential framework of Mexican identity in furniture design, using a semiotic point of view. The main purpose of this research is to distinguish the features of the Mexican culture and to analyze their application as identity in furniture design in Mexico. The image of the mexican furniture presents reminiscences in the decorative part and volumes derived from the Spanish furniture that are identified through the semiotics of the furniture image.

El turismo sostenible se sustenta en una serie de criterios que modelan la forma de hacer turismo, para ello la OMT ha establecido 12 objetivos vinculados a los pilares de la sostenibilidad. Se propone además que el turismo sostenible se sustenta en una visión holística que permite y promueve la calidad de vida tanto de los que la ofrecen, como de quienes le visitan. Este modo de turismo requiere de compromiso y acciones multisectoriales, se hace mención a la experiencia de Costa Rica y se reconocen algunos factores diferenciadores incluyendo la importancia que tiene reconocer que por más pequeño que sea su aporte, como país o persona, no debemos escatimar esfuerzos para avanzar en la sostenibilidad. Finalmente se recuerda el valor que tienen los productos competitivos y sus requerimientos en las ofertas de los destinos, cuando estos buscan consolidarse o trabajan sobre su estado de madurez, tal es el caso de Costa Rica.

Pleurotus ostreatus is a saprophytic fungus that grows mainly on living or dead lignocellulosic substrates, poor in nutrients and with low levels of minerals and vitamins. The propagation of this organism requires lignocelullosic substrates. This fungus is edible with important functional properties. Because the population of trees located in the gardens of the University of Sciences and Arts of Chiapas generates a considerable amount of organic waste, these can be used as raw material for the cultivation of fungi. Two cultures of the mushrooms were carried out in different substrates, the first from leaves of benjamina (Ficus benjamina) and the second was a combination of fig leaves (Ficus carica) and capulín (Prunus serotine). The edible mushrooms obtained from the cultures were dehydrated by convection of hot air at 50 ° C for 24 hours, then ground and stored for disposal in the integration of edible paste formulations. This food has become a staple food in the home because of the variety in processing and consumption, however, its protein content can be low and of poor quality. Therefore, it is necessary to incorporate other sources of protein of better quality without altering eating habits or organoleptic characteristics. In this work we studied the nutritional composition and consumer acceptance that results with the addition of mushroom flour in the production of fettuccine pasta. Addition levels were 10% and 20% mushroom meal (HS), the chemical composition (crude protein, carbohydrates, fiber, fat and ash) of both formulations was analyzed based on the AOAC (2000). The results indicated a considerable increase in the percentage compositions of fiber and protein when 20% HS was added to the fettuccine type pasta formulation with respect to the reported sample without the addition of the mushrooms. In addition, the levels of taste perceived by the sensory judges, for the attributes of smell and taste, were also high when 20% HS was incorporated with respect to the fettuccine control paste. This proposal can be considered useful for the preservation of mushrooms, since when dehydrated, despite the low yields, it can become an apt and versatile condiment, because it increases the nutritional components and improves the sensory properties of this type of food, without demeriting the sustainable use of waste from plants in university gardens.

This paper focuses on the duality of female characters in two texts written by José Revueltas, an acclaimed Mexican writer devoted to denounce politics and social structures. The first story is El apando, a short novel, the second is “Dormir en tierra” a short story. First I will provide an overview about how women evolve in the last manuscripts and what view are about them from the masculine eye and the female eye. That is to say, the way men and women are seen, will depend on their role: mother, life partner, prostitute, lesbian, worker, worker trafficker. The femininity, in Revueltas writings is not idealized as we were taught, thus motherhood is not something to be glorified, and the prostitute’s role is not judged or demonized either. In this cases, women characters will present nuances to which are not accustomed to see and read. Especially, this paper will examine how mother and prostitute coexist despite the fact that, in the Mexican culture, they are not commonly found mixed in the same situation. Until now it seems impossible that a woman can be both, we are used that the maternal figure should not be presented with sexual charge in the same manner that a prostitute cannot exercise the rights of mother. Finally, we will see how the grotesque aesthetics of both Revueltas’ writings encompass not only the woman, whether mother, prostitute or the two of them, but also the rest of the characters as well.

This document analyzes, from the study of transnationalism, the mechanisms and strategies implemented by home towns associations to maintain social, religious, political, family and economic relations between migrant communities and societies of origin: takes as a case study the Transnational Home town association San José. The analysis of this organizations shows how relationships and links between family and community are expanding, including organizational strategies and leadership that lead to social infrastructure projects and community services. This reflects the formation and operation of a solid social capital, which procedurally defines the identities of the migrant subject with bases to the intervention in the place of origin; Agua Verde, Sinaloa. As a methodological strategy, a qualitative approach was implemented through the documentary review, taking as an analytical axis the transnationalism, social capital and habitus. Likewise, personal interviews were used in this migrant community to document the links and identity recognition of the migrants.

The present investigation facilitates elements on the creation and narration of fables for students with intellectual disability, it was applied in the school Camilo Cienfuegos Gorriarán of the municipality of Placetas, Villa Clara, Cuba. The objective to build as a result of an investigation-action-participativa, a Notebook of fables for the formation of elementary notions of sustainable agriculture, in the students with intellectual disability. The social, psychological and pedagogic value was defined in the creation and narration of the fables; the elementary notions of sustainable agriculture that a students with intellectual disability for his social inclusion; the conception of the characters of the created fables; the moral dedicated to the conservation of the environment from the sustainable agriculture; the component game and the attention to the diversity. The methods used for the investigation in they were: analysis of documents, the investigator's newspaper, informal groups of discussion, it proves pedagogic and I study of multiple case; applied during four years. The results that they are obtained in the investigation they evidence that the creation and narration of fables impacts favorably in the affected processes of the thought, in the vocabulary, the memory and the spheres of the personality of the students with intellectual disability and it forms the elementary notions of sustainable agriculture, as content of the Environmental Education.

During the execution of engineering Works, it is common that the soil that one wishes to use does not meet the quality criteria that the corresponding regulations require to guarantee the structural stability of the structures. For those cases in which the value of the soil plasticity index exceeds the maximum allowed, the chemical stabilization has shown the best results. In this research, a comparative analysis of the performance of calcium oxide (CaO) or quicklime, and sodium chloride (NaCl) or salt, as stabilizing agents. These chemical agents were added in different proportions to the soil under study. The variations of the liquid limit, plastic limit, and the plasticity index were monitored. The results showed, contrary to what is traditionally expected, that for the case of the soil under study the best stabilizing agent is sodium chloride, because not only is it more effective in reducing the plasticity index, but also is cheaper than the quicklime.

Analysis of concentration and dispersion of the indigenous population of Hidalgo’s state aims to identify the strategy of territorial occupation followed by the main indigenous populations while monitoring population growth experienced in the last forty years from 1970 to 2010. In this way, it will quantify the evolution in space and growth, of indigenous language speaking population, at time for the five major ethno-linguistic groups to conclude whether their populations have managed to remain, expand or locate in way to extinction.
