Criação do espaço de habitar como um processo colaborativo

A criação do espaço de habitar está na origem do Homem. Através do seu entendimento da paisagem, o Homem foi ao longo dos tempos adaptando o seu espaço segundo as suas atividades e necessidades específicas. Desde o abrigo até à casa contemporânea, novas formas foram sendo criadas e adaptadas, acompanhando a evolução humana, baseada nas novas formas, atividades e requisitos definidos na realização pessoal. Numa época onde os requisitos habitacionais são cada vez mais estritos na garantia de um conforto e segurança padronizada, verificamos a existência de díspares formas de habitar. Juntamente com a valorização contemporânea dos direitos humanos podemos entender grande parte da população não tem o devido acesso a espaços verdadeiramente adaptados aos seus requisitos de habitar. Socialmente encerrados em torno de uma civilização globalizada, vivemos cúmplices de uma desigualdade social, que não consegue garantir o direito a uma habitação adequada para todos. Desta forma procura-se perceber as causas das falhas no cumprimento dos direitos humanos fundamentais e das desigualdades no sector habitacional. Entendendo o papel fundamental das populações e do sector da construção na criação dos seus habitares e tentando esclarecer o papel fundamental da arquitetura na requalificação dos espaços de habitar, oferecendo soluções e formas práticas acessíveis a todos os habitantes para a construção de um futuro sustentável, adaptado e dignificante da vida humana; ABSTRACT: The creation of the space of inhabiting is in the Man’s origin, through his under- standing of the landscape, the Man was along the times adapting his space second their activities and specific needs. From the shelter to the contemporary house, new forms were being created and adapted, accompanying the human evolution, based on the new forms, activities and defined requirements in the personal accomplishment. In a time where the habitational requirements are more and more strict in the warranty of a comfort and standardized safety, we verified the existence of disparate ways of inhabiting. Together with the contemporary valorization of the human rights we can understand great part of the population doesn’t have the access to spaces truly adapted to their requirements of inhabiting. This way we try to notice the causes of the flaws in the execution of the fundamental human rights and of the inequalities in the habitational sector. Understanding the fundamental paper of the populations and of the construction sector in the creation of our inhabit and trying to explain the fundamental paper of the architecture in the qualification of the spaces of inhabiting, offering solutions and accessible practical forms to all of the inhabitants for the construction of a maintainable future, adapted and dignifying the human life

Propolis components accountable for bactericidal accomplishment and antibiofilm activity

This study aimed at evaluating antimicrobial and antibiofilm activity of phenolic compounds present in propolis ethanol extracts (PEE). Seventy per cent ethanol extracts from seven types of propolis, one Green, two Red and four Brown collected in four Brazilian States were prepared and total phenolics, flavonoids, tannins and anthocyanins were assessed by high-performance liquid chromatography (HPLC). Minimum bactericidal concentration (MBC) and inhibitor effect on Staphylococcus aureus biofilm formation and capacity to disrupt established biofilms were assessed towards eight S. aureus isolates from milk of small ruminants with mastitis, one methicillin-resistant S. aureus (MRSA) and S. aureus ATCC 25923. To evaluate different propolis components accountability for bactericidal accomplishment and antibiofilm activity, the results were analysed by the non-parametric Spearman coefficient. Results of phenolic compounds were 216,21 to 312,08 gallic acid milligram equivalent per extract gram (mg EGA/g) of total phenolics, 55,08 to 140,6 quercetin milligram equivalent per extract gram (mg EQ/g) of flavonoids, 118,51 to 3766,16 catechin milligram equivalent per extract gram (mg EC/g) of tannins and 1,03 to 8,39 milligram per extract gram (mg/g) of anthocyanins. Red1 and Red2 showed higher tannin contents, while Red2 exhibited superior amount of anthocyanins and total phenolics. Brown3 presented higher flavonoid quantity. Green, Red1 and Red2 PEE showed the lowest levels of flavonoids, but the higher antimicrobial activity. Most PEE exhibit bactericidal activity at a concentration of 1.6 mg/mL. Brown4 PEE showed the worst capacity to inhibit S. aureus. Green PEE showed to be the most efficient in both preventing and disrupting biofilm. All PEE studied exhibited a better inhibitory activity prior-to than post-biofilm formation. According to non-parametric Spearman correlation analysis, there seems to be a significant negative correlation between the ability to disrupt biofilm and both tannins and anthocyanins contents.
