REENGINEERING THE CONCEPT OF URBAN CARS: A CASE STUDY

Based on a previously developed mathematical model for fuel consumption of a modular car, here we discuss the cross impacts of engineering scenarios vs. flexibility in use for modular vehicle architectures to achieve the reduction of CO2 emissions targeted by the European Union, in 2009. A systems perspective is adopted in conceptualizing a modular architecture of vehicles. From a theoretical viewpoint, we found modular architecture of vehicles a potential design strategy to minimize fuel inefficiencies and, thus, a strategy for design for environment.

Bioactive albumin functionalized polylactic acid membranes for improved biocompatibility

Biocompatibility is a major challenge for successful application of many biomaterials. In this study the ability to coat chemically and enzymatically activated poly(L-lactic acid) (PLA) membranes with heat denatured human serum albumin to improve biocompatibility was investigated. PLA membranes hydrolyzed with NaOH or cutinase and then treated with 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide, hydrochloride (EDAC) as a heterobifunctional cross-linker promoted the coupling single bondCOOH groups on PLA membranes and single bondNH2 groups of heat denatured human serum albumin. This resulted in increased hydrophilicity (lowest water contact angles of 43° and 35°) and highest antioxidant activity (quenching of 79 μM and 115 μM tetramethylazobisquinone (TMAMQ) for NaOH and cutinase pretreated membranes, respectively). FTIR analysis of modified PLA membranes showed new peaks attributed to human serum albumin (amide bond, NH2 and side chain stretching) appearing within 3600–3000 cm−1 and 1700–1500 cm−1 (Fig. 3). MTT studies also showed that osteoblasts-like and MC-3T3-E1 cells viability increased 2.4 times as compared to untreated PLA membranes. The study therefore shows that this strategy of modifying the surfaces of PLA polymers could significantly improve biocompatibility.

“Primeiro-Mnistro defende que a investigação, ciência e inovação é ‘decisiva’ para o crescimento económico”…

Afinal, ficamos a saber que a austeridade, tantas vezes chumbada no Tribunal Constitucional, era uma estratégia para investir na Investigação, Ciência e Inovação europeias! É uma boa altura para aumentar, de modo justo e proporcional, todos os orçamentos de todas as universidades e politécnicos portugueses, os quais têm relações privilegiadas com África, Brasil e parte da Ásia, uma evidente mais-valia para a União Europeia! Abstract: After all, we learn that the austerity so often sinker in the Constitutional Court, was a strategy to invest in Research, Science and European Innovation! It is a good time to increase, fair and proportionate manner, all the budgets of all Portuguese universities and polytechnics, which have a special relationship with Africa, Brazil and parts of Asia, an asset apparent to the European Union!

"Procedural Strategy" by Carlos Pinto de Abreu, lawyer

Como Carlos Pinto de Abreu refere e bem, no seu livro e no seminário, entre juízes, partes ou sujeitos processuais, advogados ou solicitadores, magistrados do Ministério Público ou testemunhas, peritos ou funcionários, encontramos “pessoas que podem ser mais ou menos sérias”, por sinal “motivadas por outros interesses que não os de servir a Verdade e a Justiça”; Abstract: Carlos Pinto de Abreu as regards and well in his book and seminar, between judges, parties or procedural subject, lawyers or solicitors, prosecutors and witnesses, experts or officials, found "people who may be more or less serious" , by the way "motivated by interests other than those serving the Truth and Justice".

IDEA MANAGEMENT SYSTEM - AN ESSENTIAL COMPONENT IN THE CONTINUOUS IMPROVEMENT OF QUALITY AND INNOVATION

It is known the power of ideas is tremendous. But there are employees in many companies who have good ideas but not put them into practice. On the other hand, there are many others who have good ideas and are encouraged to contribute their ideas for innovation in the company. This study attempts to identify factors that contribute to success in managing ideas and consequent business innovation. The method used was the case study applied to two companies. During the investigation, factors considered essential for the success of an idea management program were identified, of which we highlight, among others, evidences the results, involvement of the top management, establishment of goals and objectives; recognition; dissemination of good results. Companies with these implemented systems, capture the best ideas from their collaborators and apply them internally. This study intends to contribute to business innovation in enterprises through creation and idea management, mainly through collecting the best ideas of their own employees. The results of this study can be used to help improving deployed suggestions systems, as well as, all managers who wish to implement suggestions systems/ideas management systems.
