Estudo preliminar dos efeitos do aquecimento global sobre a floração da oliveir...

Simpósio Nacional de Olivicultura, 5º, Santarém, 24-26 de Setembro, 2009 ; Phenological development of the olive tree is important for studying its adaptability, for management and simulation of growth and yield of olive orchards. Nevertheless, most studies that predict the date of flowering of the olive do not consider its chilling requirements, that are low, but may not be satisfied in some years, under mild...

Spatial pattern recognition of extreme temperature climatology: assessing HadCM...

This article attempts to quantify the spatial uncertainties associated with extreme temperature’s response, by assessing data derived from climate model. This is undertaken by a comparison of the spatial pattern of a long-term time-series aggregation (1960/61-1989/90) for extreme temperatures simulated by a particular GCM (the UK Met Office - Hadley Centre climate model, HadCM3) to that of the USA NCAR NCEP Rea...

Double Critical Phenomena in (Water + Polyacrylamides) Solutions

Aqueous solutions of a copolymer derivative of a polyacrylamide showed very interesting behavior, that in which the system evolves from one kind of double criticality (pressure−hypercritical point) to another (temperature−hypercritical point) as polymer molecular weight decreases. While in the neighboring region of the former point one expects a change from contraction to expansion upon mixing with increasing p...

Phase behavior of (polyacrylamides + water) solutions: concentration, pressure ...

Phase diagrams of poly(N-isopropylacrylamide) (PNIPAAM) as well as of hydrophilically-modified copolymers in aqueous solution were determined. A high-accuracy He-Ne Laser scattering technique was used for the detection of operational spinodal (sp) and cloud-point (cp) curves. Polymer concentration was varied from 0.5 to 20 wt.%. In the case of copoly(PNIPAAM/vinylsaccharide) several different chain lengths were...

Avaliação da resposta do Plasmodium falciparum à cloroquina, quinino e mefloquina

Nosso estudo envolveu a análise de cepas de Plasmodium falciparum provenientes da Região Amazônica Brasileira, coletadas no Laboratório de Malária da SUCEN. Os estudos "in vitro" foram efetuados com a cloroquina (46 ensaios), quinino (42 ensaios) e mefloquina (51 ensaios). Os resultados mostraram resistência de 100% em relação à cloroquina, 2,4% ao quinino e 31,4% à mefloquina, na análise "in vitro". Sete pacie...
