Evaluation of seasonal dynamics and bioindication potential of macroalgal communities in a polluted tropical stream

Macroalgal communities and environmental variables were analyzed seasonally along a polluted tropical stream in São Paulo State, Brazil, We aimed to improve the knowledge of tropical macroalgal communities, to study the longitudinal and seasonal dynamics of these communities in influenced environments, to evaluate the relationship of algal frequency and abundance with selected environmental variables, and to look for potential macroalgal species indicators. The seasonal abundance pattern was similar to natural or low influenced systems and was mainly determined by rainfall regime. However, community composition was closely related to some chemical water pollution indicators, such as phosphorus and nitrogen compounds. Some species are suggested as potential indicators of organic pollution (e.g. Oscillatoria ornata, Stigeoclonium helveticum and Schizomeris leibleinii), but more detailed studies have to be developed to determine the tolerance limits of these species. on the basis of our results and literature data, the use of occurrence of Oscillatoriales in relation to other orders of Cyanoprokaryota is suggested to be a good indicator of organic pollution in tropical lotic ecosystems.

Ceramic materials in dentistry: historical evolution and current practice

Dental ceramics are presented within a simplifying framework allowing for facile understanding of their development, composition and indications. Engineering assessments of clinical function are dealt with and literature is reviewed on the clinical behaviour of all-ceramic systems. Practical aspects are presented regarding the choice and use of dental ceramics to maximize aesthetics and durability, emphasizing what we know and how we know it.

Identidades e diferenças: o caso da guerra civil na antiga Iugoslávia

Abstract: The civil war in the former Yugoslavia (1991 - 1995) had a strong ethnicreligious component. In an attempt to maintain the cohesion of an artificially created state post-first World War, identities were sought and accepted - and institutionalized - the differences between the various peoples that constituted the "land of the South Slavs". From the 1980s the differences were highlighted during the war and taken to the extreme, especially in the territories of Croatia and BosniaHerzegovina. From literature and the author's personal experience and using concepts of culture, ethnicity, identity, difference, belonging, nation and state, the text shows how the ethnic-religious differences were used during the civil war in Yugoslavia to claim possession of territories, strengthen discourse of the impossibility of coexistence, overvalue potential threats and fear and justify the perpetration of crimes against humanity.

Acrylic resin cytotoxicity for denture base - Literature review

Acrylic resin is a widely used material in clinical practice, and a satisfactory biocompatibility is essential. When the resin polymerization reaction is incomplete, residual monomers are released into the oral cavity. The aim of this study was to evaluate, through a literature review, the cytotoxicity caused by the denture base acrylic resin used, and its components. The selection of published studies was performed on the Pubmed database from January 2008 to July 2013. The keywords used were: cytotoxicity and acrylic resins, cytotoxicity and denture base resins and cytotoxicity and oral prosthesis. Inclusion criteria were: in vitro studies and literature reviews published in English that evaluated the acrylic resin cytotoxicity for denture base and its components. Studies with no reference to the search strategy were excluded. A total of 182 articles were found. Among these, only 13 were included for writing this review. The MTT test is the most common test used to evaluate acrylic resin cytotoxicity. Auto-polymerized resin is more cytotoxic than heat-polymerized resin because of its higher quantity of residual monomers which cause cell and tissue changes in the oral mucosa. However, more studies are necessary for the development of biocompatible materials.

Pólis vs. Oikos: a investigação do papel feminino no drama grego

This work analyzes the consequences of the intersection between the two spheres polis and oikos. It does so by examining themes present in three plays: Medea, Agamemnon and Lysistrata. The focus of the analysis is the way in which the feminine characters react to conflicts of interests in their respective situations. To fully comprehend which values correspond to which mentioned institution, the work also necessarily investigates the socialization and functions of both genders in fifth-century Athenian society. The analysis of the feminine condition in the creation myth implies the importance of the misogynistic sense of that time, which culminated in the silencing, discrediting, and systemic repression of females. The role of women in society, instilled in all girls starting in early childhood, is to succeed in marriage and domestic permanence. This lies opposite the masculine role, which was focused outside of the family center and to environments relating to war and public life. Matrimony and family, traditional female values, were threatened when overlapping with male interests, such as unavoidable war or social ascension through a different matrimonial bond. Therefore, it is possible to affirm that the opposition evident in the definitions male vs. female indicates that, in certain contexts, the interests of each element cause the conflicts present in the chosen plays
