18. Orientações pfaffianas e o furtivo grafo de Heawood / Pfaffian orientations and the elusive Heawood graph
A graph G that contains a perfect matching is Pfaffiano if there is an orientation D of the edges of G, such that every conformal circuit of G is oddly oriented in D. A subgraph H of G is conformal if G - V (H) has a perfect matching. A circuit with an even number of edges is oddly oriented if the number of edges whose orientation in D agrees with any sense

22. Toxicity of a cyanobacterial extract containing microcystins to mouse lungs
Toxic cyanobacteria in drinking water supplies can cause serious public health problems. In the present study we analyzed the time course of changes in lung histology in young and adult male Swiss mice injected intraperitoneally (ip) with a cyanobacterial extract containing the hepatotoxic microcystins. Microcystins are cyclical heptapeptides quantified by E

24. Higiene das mãos: comparação da eficácia antimicrobiana do álcool - formulação gel e líquida - nas mãos com matéria orgânica. / Hand hygiene : antimicrobial activity comparison of three alcoholic produts - gel and liquid - in hands with organic material.
Hand hygiene is considered the most important measure to reduce the transmission of nosocomial pathogens in health care settings. Because alcohol has excellent antimicrobial activity, requires less time, results in less skin irritation and does not require proximity to a sink, is the preferred agent for hand hygiene. In the face of scientific evidence, there
