Introduction: It is known that self-etching adhesive systems can act as semi-permeable membranes. Objective: Evaluate the effects of additional layer of hydrophobic resin on the microtensile bond strength of self-etching one-bottle adhesives. Material and method: Sixty bovine incisors were used in this study. The facial enamel surfaces of the crowns were abraded with silicon carbide paper to expose flat, mid-coronal dentin surfaces. The following adhesives were used: Clearfil Tri S Bond (CTSB), AdheSE One (ADH) and One Coat 7.0 (OC). Each material was tested with and without applying an additional layer of hydrophobic material from the same manufacturer. Z-350 composite resin was inserted in three 1 mm increments. All adhesive restorative procedure was performed under simulated pulpal pressure and the microtensile test was performed immediately after curing the composite resin. Data were submitted to ANOVA and Tukey test (p < 0.05). Result: For all adhesives tested, the worst results were observed in groups which the additional layer of hydrophobic resin was not applied. Conclusion: The application of additional layer of hydrophobic material can improve the adhesion of self-etching all-in-one adhesive systems.

In this work we intend to study how union is understood by men and women from their idealizations and expectations. We aim to survey how the contemporary society discourse about union is interpreted, absorbed and experienced by couples who are united for a certain time and those individuals who intend to establish a stable union, as well as whether there is a connection between the romantic view of peer relationships and the reality experienced by people. In other words, we aim to find out which influences the social changes bring to the conjugal relationship and what expectations they bring to it, to establish if the gender affects the relationship expectations, and analyze to which extent and how these expectations contribute to the development and maintenance of conjugal conflicts.

The perception of modern society regarding the nature and indigenous peoples came to be shaped in the sixteenth and seventeenth centuries, with two major events, the invasion of Europeans in America and the scientific revolution. These events symbolize the cultural overlap and European thinking about the rest of the world. The current scenario is industrialism, consumism and cultural standardization driven by Cartesian thought. This work demonstrates, through literature research and data analysis, that this dominant model has caused the crisis of modernity, focusing especially on the environmental crisis that threatens human life. The solutions are present in the modern society the knowledge of indigenous peoples that is inherently ecological and sustainable by tradition. From the union of diverse cultures and knowledge dialog you can find solutions for today's problems and provide a renewal of relationships between modern society, indigenous peoples and nature. The World Conscious Pact presents this proposal which can be increased through public relations strategies in order to reconnect the man-nature bond, generating critical behavior with respect to the current dominant system and motivate society to adopt truly ecological postures. For this it is necessary to rescue the Earth image as a mother

There is little information regarding bond strengths of polyglass to metal alloys. This study evaluated the influence of bonding system on shear bond strength of a composite resin (Artglass/Heraeus Kulzer) to cast titanium (Ti). Twenty metallic structures (4mm in diameter, 5mm thick) of titanium grade I were cast shaped and abraded with 250mm aluminum oxide and separated into two groups. For each group was applied one bonding system (Siloc or Retention Flow) before opaque and dentin polymer superposition. This procedure was managed using teflon matrices. They were manipulated and polymerized according to the manufacturer's recommendations. The samples were stored in distilled water for 24 hours at 37º and thermocycled (5º and 55ºC/500 cycles). Shear bond strength tests were performed by using an Instron Universal testing machine at a crosshead speed of 5mm/min. Results were analyzed statistically with one-way ANOVA (a=0,5) and they indicated that the Retention Flow system was statistically better than Siloc (20.74 MPa and 11.65 MPa , respectively). It was possible to conclude that the bonding agent influenced the adhesion between polymer and cast titanium.

Os movimentos conservacionistas, desde a década de 80, impulsionam a predileção por produtos cujos fabricantes visam à sustentabilidade, ou seja, à degradação mínima do meio ambiente na produção e no consumo da sociedade atual, de modo a não comprometer os recursos naturais para as gerações futuras. Essa tendência fez países, a início os desenvolvidos, criarem regras, regulamentos ou normas de produção visando à preservação ambiental, a serem seguidas na produção por outros países com quem desejam estabelecer comércio. O que pode se configurar, principalmente para os países em desenvolvimento, uma barreira comercial - geralmente não tarifária - difícil de transpassar. O Brasil, como país em desenvolvimento e grande fornecedor de produtos primários para o exterior, enfrenta frequentemente essas barreiras comerciais com propósitos ambientais, muitas vezes de forma não planejada. Isso provoca, especialmente em pequenas e médias empresas, um aumento dos custos de produção e dificuldades de competir no mercado internacional. Este trabalho procura expor os principais produtos que sofrem notificações ambientais, mais especificamente dos Acordos SPS e TBT, e estabelecer uma relação entre essas notificações e a pauta exportadora brasileira durante o período de 1997 a 2014
