User Experience (UX) is one of the most important attributes for the success and quality of a software product. UX explores how a person uses an application, and the emotional and behavioral consequences of such use. Although several UX evaluation methods allow gathering information on the reasons for a poor UX, some of them tend to make users feel uncomfortable, such as asking direct questions...

A RBO faz 50 anos e ganha um presente This year, the RBO will be 50 years old! The history of the RBO began in 1965. After a difficult start led by Marcio Ibrain, it was kept going for a long time through the dedication of our dearly missed friend, Donato, who was followed by Giesta. This history has already been narrated in this space. We started our activity in the RBO in 2009, nominated by t...

The microsymbiont population in soybean root nodules (Glycine max L. cv Williams 82 inoculated with Bradyrhizobium japonicum 2143) was characterized during symbiotic development to determine the extent of heterogeneity in this population. The microsymbiont population was isolated by centrifugation through a continuous sucrose gradient (44 to 57% weight to weight ratio) and appeared homogeneous ...

Multi AXis Differential Optical Absorption Spectroscopy (MAX-DOAS) observations of the oxygen dimer O4 are presented which can serve as a new method for the determination of atmospheric aerosol properties. Like established methods e.g. sun radiometer and LIDAR measurements MAX-DOAS O4 observations determine optical properties of aerosol under atmospheric conditions (not dried). However, the nov...
