1. Qualidade da água do escoamento superficial urbano: revisão visando o uso local. / Water quality from initial urban run-off: revision seeking local use.
This work was conducted aiming a master degree in Engeneering in Escola Politécnica of Universidade de São Paulo, and deal with secondary data obtained in fields researches about rain water quality in the initial run-off. This research intended to propose and to discuss the concept of use of the water from initial run-off, as one of the tools to develop

2. CLARIFICAÇÃO DE ÁGUAS PLUVIAIS RICAS EM ÓXIDOS DE FERRO ACUMULADAS EM CAVA DE MINERAÇÃO ATRAVÉS DA UTILIZAÇÃO DE UM COAGULANTE NATURAL, A MORINGA OLEIFERA
The surface waters, which run off over the slopes of a trench of the Mina de Alegria Mariana (MG), carry solid particles of several dimensions, which settle in the bottom. These waters have high turbidity, red colour and high stability of the suspended particles, basically constituted by iron oxides (hematite e goethite). To allow the maintenance of the mini

3. RNA template-directed RNA synthesis by T7 RNA polymerase.
In an attempt to synthesize an oligoribonucleotide by run-off transcription by bacteriophage T7 RNA polymerase, a major transcript was produced that was much longer than expected. Analysis of the reaction indicated that the product resulted from initial DNA-directed run-off transcription followed by RNA template-directed RNA synthesis. This reaction occurred

4. A new target for CRP action at the malT promoter.
In Escherichia coli, the transcription of the malT gene is activated by the complex formed between cAMP and its receptor protein, CRP. Kinetics of formation of polyribonucleotide products from the corresponding promoter were studied in vitro by two sets of techniques, abortive initiation assays and run-off experiments. The first type of assay indicated that

5. Anoxia-hyperoxia induces monocyte-derived interleukin-8.
Ischemia-reperfusion and hyperoxia-induced pulmonary injury are associated with the presence of activated neutrophils (PMN) and cellular injury. Although the signals orchestrating the directed migration of these PMN during the pathogenesis of these disease states remain to be fully elucidated, it appears they may be dependent upon the production of certain n
