The treatment of domestic sewage becomes an alternative of water and nutrients in agricultural cultivation, and must meet the criteria defined by legislation. Thus, this work aimed to evaluate the pathogenic load of the treated effluent, coming from a TEE, before and after the application of ultraviolet disinfection, demanding agricultural reuse. Weekly samplings were performed before and after ultraviolet disinfection (A / UV and D / UV) to characterize pH, turbidity, electrical conductivity (CE), dissolved oxygen (OD), total organic carbon (COT), total coliforms (CT) and thermotolerant (CThermo), as well as total nitrogen (NT). Between the raw effluent and the other sampled points A/UV and D/UV, important differences: pH, CE, OD, turbidity and NT. For COT there was no difference between the A/UV and D/UV points. CT and CThermo differed among all sampled points. It is concluded that the ultraviolet sterilizer presents efficiency in the elimination of bacteria despite the fact that the final microbiological load does not fit the current legislation, which makes the agricultural reuse of the treated effluent impossible.","PeriodicalId":360346,"journal":{"name":"Revista Cincia, Tecnologia & Ambiente","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122910788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The so-called secondary are produced most often with cardboard or wood. Thus, the differential of this study is the use of forest waste as a raw material to produce secondary packaging. The aim of this research was to evaluate the potential use of OSB panels of Balsa wood [Ochroma pyramidale (Cav. Ex Lam.) Urb., Malvaceae] for the production of secondary display type packaging. In this study, the physical and mechanical properties of medium density OSB panels (650 kg.m-3) produced with 13% polyurethane resin based on castor oil were analyzed in order to verify the potential of this material for use in the manufacture of packaging; a model of secondary packaging of the display type was proposed and also, a study of sensory analysis was carried out in order to identify the acceptance of this product by the users. Results obtained demonstrated the viability of structuring the secondary display type packaging for food products with OSB panels of residual Balsa wood, due to the verification of the suitability of the physical and mechanical properties of this material for use as a constituent of secondary packaging. Sensory analysis indicated acceptance of the new product by users of secondary display packaging for food.","PeriodicalId":360346,"journal":{"name":"Revista Cincia, Tecnologia & Ambiente","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121663122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We selected 10 sites within the urban area of the city of Santa Helena, western Parana state, southern Brazil, to conduct 5-minute point counts and used occupancy modelling and logistic regression to determine the aforementioned parameters. The probability of detecting the species is suggested to halve as a function of time, while its occupancy probability alone was not related to the levels of afforestation or noise pollution; the number of houses around point counts showed a positive influence on their detection. When we analyzed the probability with the variables together and their interactions, our results suggest that Great Kiskadee is well adapted to urban environments.","PeriodicalId":360346,"journal":{"name":"Revista Cincia, Tecnologia & Ambiente","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122660477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Porem, em florestas degradadas, trepadeiras hiperabundantes podem afetar a chegada de sementes no solo. Neste trabalho, descrevemos o banco de sementes de especies arboreas em um fragmento degradado de Floresta Estacional Semidecidua e testamos a hipotese de que trepadeiras afetam negativamente o banco. O solo superficial foi coletado em 26 pontos do fragmento em 2015 e em 2016, e colocado em casa de vegetacao para germinacao das sementes. Os individuos arboreos emergidos foram contados e identificados. Em cada um dos pontos de coleta do solo, estimou-se o grau de cobertura do dossel por trepadeiras. Nos dois anos, foram encontradas as mesmas cinco especies no banco de sementes, todas autoctones e com sementes ortodoxas (formam bancos pouco persistentes ou persistentes). Nao houve diferenca na riqueza e na abundância do banco entre os graus de cobertura do dossel por trepadeiras. A baixa riqueza pode ser explicada por diferentes fatores que diminuem o sucesso reprodutivo das plantas, como os relacionados a propria fragmentacao. A ausencia de especies aloctones indica que especies provenientes de outras areas nao estao sendo incorporadas no banco de sementes, nao havendo, assim, colonizacao do fragmento. Diferentemente do esperado, a cobertura do dossel por trepadeiras nao influenciou a incorporacao de sementes no solo. Conclui-se que a regeneracao do fragmento esta comprometida, mas isso parece ser explicado por fatores que atuam sobre a regeneracao de forma mais intensa do que o grau de cobertura do dossel por trepadeiras.","PeriodicalId":360346,"journal":{"name":"Revista Cincia, Tecnologia & Ambiente","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127437256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We tested whether the perception of people on pollination change among productive and consumption sectors, and if it is influenced by the degree of schooling, using the production-chain of the passion fruit as study model, which demands crossed-pollination provided by large-sized bees. The perception of people along five sectors was evaluated from production to consumption, interviewing 162 people with a questionnaire on passion-fruit pollination. With a correspondence analysis, we correlated each production and consumption sector to the knowledge about pollination presented by them. The understands of each sector was related to the type of education that they received previously (formal/scholar vs. non-scholar, including non-formal education and courses) through a Kruskal-Wallis test. Sellers of inputs and farmers were correlated to perceive bees in a positive way, know more correct concepts about pollination and bee species, and praised large-bees in agriculture, compared to other sectors. Consumers perceived bees in a negative way, know fewer correct concepts on pollination, and associated them with food and not with ecosystem services. However, consumption sectors acknowledged bees as valuable and supported initiatives for pollinator-friendly agriculture. The higher degree of schooling lead to more knowledge on pollination among the sellers, but not in other sectors. In general, familiarity to the subject provided by experience and by non-scholar education increased the understanding about pollination. The insertion of ecosystem services in the daily life of people shall contribute to fixate knowledge and change the negative perceptions about ecosystem services and promote conservation policies.","PeriodicalId":360346,"journal":{"name":"Revista Cincia, Tecnologia & Ambiente","volume":"164 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124588367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
