Importância da avaliação do ciclo de vida na análise de produtos: possíveis aplicações na construção civil

Much has been discussed lately about reusing waste in new construction materials and countless studies have been carried out based on this objective. However, before these products can be called “sustainable” and a recycling system can be effectively implemented, it is fundamental for all the aspects involved in this action to be understood, and more important, what are the true gains for the productive sector and what are the benefits for the environment if this was to occur. In order to obtain a general framework for all environmental aspects and potential impacts associated with these products, over their entire life cycle, the most appropriate methodology is the Life Cycle Assessment (LCA). In view of the above, the objective of this work is to provide an overview of current studies of LCA, its history, its importance, its standards and the methodology employed and its applications related to civil construction. It is expected, to obtain a more complete scenario of the influences from a study of LCA, as well as establishing a contribution for the assessment of specific products and processes for civil construction, disseminating the importance of the use of this tool within the sector.

Avaliação do efeito da inclinação e umidade antecedente na qualidade e quantidade das parcelas escoadas, percoladas e armazenadas em telhado verde extensivo

This study investigated the effect of slope and antecedent soil moisture on the water depth stored and percolated on extensive green roofs built in pilot scale. For this purpose, slopes of 10, 20 and 30% were investigated. Moisture was measured before and after each test in order to determine the differential moisture (∆U). The experimental runoff and percolated flow were analyzed by varying moisture and slope. Apparent color and turbidity were measured on runoff and percolated flow for each one of the modules. The results yielded that for the slopes of 10% the smaller values of runoff was obtained (average of 1,01% ± 0,7%). For the others slopes (20% and 30%), the runoffs were around 35% ± 15%. The sum of runoff and percolated water results in 77% (average) for slope of 10% and 80% for 20% and 30%. The slope and moisture have explained 87% of data for retained water and 81% for runoff. For percolated flow the inverse trend was observed. The retained water was 11,6±1,4mm for the module with 10% of slope, around 10,0±1,2 mm for the module with 20% of slope, and about 9,5±1,1 mm for the module with 30%. The results pointed out that both slope and antecedent moisture are crucial for runoff reduction and for material transportation.

Aplicação de um método ergonômico para avaliação da permanência e atratividade em espaço público aberto: estudo de caso Parque Vitória Régia, Bauru - SP

There are several researches on evaluation of urban public space, but not all establish a relationship between the configuration of spaces with the thermal environment, ergonomics and environmental behavior of users. To understand this relationship, the aim of this paper is to present the model DEPAN (Design for Permanence and Attractiveness in niches open spaces of conviviality), based on graphical meshes, which were designed to evaluate the influence of design and ergonomics of open public spaces in the human thermal comfort and the ways in which users appropriate the space. Its applicability is demonstrated through a case study conducted in a park in the city of Bauru-SP. To perform this evaluation public space niches were chosen. They were formed by morphological elements and street furniture and defined by their spatial arrangements. The collected data were incorporated into a Geographic Information System (GIS), which allowed the overlay of meshes. The results indicate that the DEPAN model allows the verification of the spatial characteristics, thermal quality and ergonomic design generated by spaces, as well as the evaluation of the influence of these aspects in the way of using the spaces. The model allows the generation of a classification for every niche and set a value for the level of service offered.

Trabalho e estresse: identificação do estresse e dos estressores ocupacionais em trabalhadores de uma unidade administrativa de uma instituição pública de ensino superior (IES)

The article presents survey of public servants of a Higher Education Institution (HEI) that aimed to diagnose the presence of stress in this population, the stress phase in which individuals find themselves and the prevalence of symptoms, whether physical or psychological. This study aimed to characterize the symptomatology of the population experiencing stress and major stressors of the work context where participants act. The survey revealed that 46.6% of the participants are experiencing stress, mostly found in the resistance phase with predominantly psychological symptoms. Among the major stressors of work contexts, stood the physical environment of the workplace, sector infrastructure work, the process of professional performance evaluation adopted by IES, low recognition given to the work done and the small number of servers in certain sectors . The results revealed the presence of stress advancement of this sample and the need for appropriate policy actions and management practices of people who aim to act to minimize this phenomenon.

Avaliação da migração de nifas de Scaptocoris carvalhoi Becker, 1967 (Hemiptera, Cydnidae) em plantas de importância econômica e invasora em teste com oportunidade de escolha

One of the factors that affect the control of brown - roots environmental bedbug is the wide availability of plant species. Thus, this study aimed to evaluate the migration of nymphs of the brown - roots between plant species of economic importance and invasive stinkbug. Eight species of plants have been established in a set formed by eight circular PVC containers, connected symmetrically with free communication to a central circular container. The experiment was arranged in a completely randomized design and consisted of eight treatments and six replications. The test evaluations were performed on 15o , 30o , 45o and 60o days after the release of the nymphs, by counting the insects that migrated to the roots of different plants. It was observed that by the 30o day of early release nymphs, no significant differences (P < 0,05) in the choices nymph by plants. B. alata at 15 days of initial release and B. alata and grass-dictyoneura at 30 days were plants that had higher migration. All counts were carried out on 45o and 60o days, the migration of U. brizantha cv. Marandu presented significantly higher than all other species tested plants nymphs.

Avaliação fitoquímica e microbiológica da espécia Artemisia annua L. submetida a tratamentos de armazenamento e condições de ambiente

The species Artemisia annua L. (Asteraceae) is native to China and has artemisinin as its main active component, substance that is considered a potent antimalarial drug. With the increased interest in natural active principles, studies related to post-harvest and storage of vegetable material become important for better conservation of its phytotherapic properties. Therefore, the present study had as objectivedefine the best storage conditions to preserve and keep the quality of phytotherapic drugs. Leaves of A. annua dried were stored for six months in polyethylene bags wrapped in Kraft paper and packed in four treatments: at ambient condition, refrigerated at 4 ± 2 oC, using normal packing, and using vacuum packing. Samples were taken for microbiological, moisture content, and level of artemisinin analyses before the experiment begun and at 30, 90, 120 and 180 days. The results of microbiological tests showed no significant contamination, as well as the moisture content of the stored (biological) material, which remain between 5% and 10%, keeping within acceptable parameters. The ambient without vacuum treatment (SVA) was the treatment that better maintained the sample stability during 180 days, however, the refrigerated without vacuum (SVR) showed greater efficiency to conserve the content of artemisinin.
