INFLUÊNCIA DE DOSES CRESCENTES DE CHUMBO SOBRE O TEOR E O CONTEÚDO DE NUTRIENTES E Pb EM MUDAS DE IPÊ-ROXO (Tabebuia impetiginosa (Mart.) Standl.)1

The effect of lead application on nutrient and Pb content and accumulation in ipê-roxo (Tabebuia impetiginosa (Mart.) Standl.) seedlings was studied in an experiment conducted under greenhouse conditions at the Soil Science Department of the Federal University of Lavras. The seedlings were cultivated in Clark nutrient solution and submitted to increasing Pb levels: 0, 48, 96, 192 and 288 μmol/l...

Inovação e Reuso: Desafios para o Ensino e a Prática do Design de IHC

In this work, we investigate the motivations of Computer Science students to consult existing Human-Computer Interaction (HCI) design solutions. We discuss the results considering theories and practices well known in the literature, and we conclude with some challenges for the teaching and practice of HCI design.

Melhorando o Desempenho do Processamento de Consultas Drill-Across em Ambientes de Data Warehousing

In this paper we propose two algorithms aimed at increasing the performance of drill-across queries in data warehousing environments. The JMG algorithm is used when numeric measures of different data warehouses are usually required together. The EG-JM algorithm extends the first one also considering storage requirements. The performance tests carried out using the TPC-H benchmark showed a huge ...
