Abstract: The bloodsucking hemipteran Rhodnius prolixus is a vector of Chagas' disease, which affects 7–8 million people today in Latin America. In contrast to other hematophagous insects, the triatomine gut is compartmentalized into three segments that perform different functions during blood digestion. Here we report analysis of transcriptomes for each of the segments using pyrosequencing technology. Comparison of transcript frequency in digestive libraries with a whole-body library was used to evaluate expression levels. All classes of digestive enzymes were highly expressed, with a predominance of cysteine and aspartic proteinases, the latter showing a significant expansion through gene duplication. Although no protein digestion is known to occur in the anterior midgut (AM), protease transcripts were found, suggesting secretion as pro-enzymes, being possibly activated in the posterior midgut (PM). As expected, genes related to cytoskeleton, protein synthesis apparatus, protein traffic, and secretion were abundantly transcribed. Despite the absence of a chitinous peritrophic membrane in hemipterans - which have instead a lipidic perimicrovillar membrane lining over midgut epithelia - several gut-specific peritrophin transcripts were found, suggesting that these proteins perform functions other than being a structural component of the peritrophic membrane. Among immunity-related transcripts, while lysozymes and lectins were the most highly expressed, several genes belonging to the Toll pathway - found at low levels in the gut of most insects - were identified, contrasting with a low abundance of transcripts from IMD and STAT pathways. Analysis of transcripts related to lipid metabolism indicates that lipids play multiple roles, being a major energy source, a substrate for perimicrovillar membrane formation, and a source for hydrocarbons possibly to produce the wax layer of the hindgut. Transcripts related to amino acid metabolism showed an unanticipated priority for degradation of tyrosine, phenylalanine, and tryptophan. Analysis of transcripts related to signaling pathways suggested a role for MAP kinases, GTPases, and LKBP1/AMP kinases related to control of cell shape and polarity, possibly in connection with regulation of cell survival, response of pathogens and nutrients. Together, our findings present a new view of the triatomine digestive apparatus and will help us understand trypanosome interaction and allow insights into hemipteran metabolic adaptations to a blood-based diet.
Allah na cidade das etnias: a inser o do grupo étnico árabe na identidade urbana de Criciúma/SC

Abstract: The city of Criciúma/SC consolidated its urban identity based on ethnicity during the celebrations of its Centenary. This identity transformation allowed the insertion of various ethnic groups into the identity of the city. Among them we can highlight the Arab ethnic group who granted their presence in the city through a festivity and the demarcation of an Arab Muslim territory whose mosque is the main element.

Dilaton Gravity with a Non-minmally Coupled Scalar Field
M. Alves,V. B. Bezerra
Physics , 2000, DOI: 10.1142/S0218271800000815
Abstract: We discuss the two-dimensional dilaton gravity with a scalar field as the source matter. The coupling between the gravity and the scalar, massless, field is presented in an unusual form. We work out two examples of these couplings and solutions with black-hole behaviour are discussed and compared with those found in the literature.
Relations between retail market and distribution in LPG range: analyzing the cooperation and alliances A Rela o entre Varejo e Distribui o na Cadeia do GLP: Analisando as Estratégias de Coopera o e de Alian as.

Revista Ibero-Americana de Estratégia , 2009, DOI: 10.5585/riae.v7i2.977
Abstract: This work aims to proceed with the evaluation of relationship between retail market and distribution in liquefied petroleum gas range (LPG), according to Network Theory. This is an exploratory research, with qualitative characteristic, about the dynamics of cooperation relations. The results, although could not be considered as conclusive, by reason of the study of only one case, shows that an alliance with relationship problems and competition, between point-of-sale and resale, probably will be dissolved as soon as the retailer become a reseller. Este trabalho tem por objetivo proceder à avalia o das rela es entre varejo e distribui o na cadeia do gás liquefeito de petróleo (GLP) com base nos pressupostos da Teoria das Redes. Trata-se de um estudo exploratório, de natureza qualitativa, acerca da dinamica das rela es de coopera o. Os resultados, embora n o possam ser considerados conclusivos, em raz o do estudo de um único caso, indicam que uma alian a, com problemas de relacionamento e com competi o, entre ponto de venda e revendedor, por conveniência, provavelmente irá ser desfeita assim que o varejista tiver condi es de se tornar um revendedor.
Values in Students of Higher Education  [PDF]

Abstract: The values of students occupy a central position in the cognitive system and on student’s personality, because it includes components of knowledge, affective and behavioural, determining their attitudes and motivations. In order to respond to the question “what are the values in students of higher education”, we have done a review of literature indexed in databases online, getting 23 articles published between 2008/2017. The reflection on the values of a student is of extreme importance to the educational system, due to the relationship between education and human values, resetting or recapturing the true role of the school in the formation of values. The results show that through the school it is possible to construct and develop human values in students, making it a place for this construction, without neglecting the importance of family. With the heterogeneity of methodologies of the studies, we suggest the development of more homogeneous research, materials and methods to evaluate the values of University students.
