    The objective of this study is not only to research the students’ perceptions of this new assessment format but also its impact in their learning. The study took place in a University in Rio de Janeiro, Brazil; the participants were 26 students from the third part of Nursing studies. Data collection was made through an instrument with open questions carried out from April to May of 2008. Results were analyzed and described in a thematic unit. Three thematic units elaborated are: the evaluation process facilitates a reliable assessment of knowledge, the students’ learning; the evaluation process facilitates a critical reflection of the questions; the assessment form requires more student effort. The students’ perceptions regarding the evaluation process follow the new perspectives of the curriculum guidelines of nursing studies, mainly in regards to educating critical and reflexive professionals.Este estudio tiene como objetivo investigar sobre las percepciones de los estudiantes acerca de esta nueva forma de evaluación así como el impacto en su aprendizaje. El escenario del estudio fue un centro Universitario del Estado de Río de Janeiro, los sujetos fueron 26 estudiantes del tercer período en el curso de Graduación de Enfermería. La recogida de datos se realizó por medio de un instrumento con preguntas abiertas, desarrollado en el período comprendido entre abril y mayo de 2008. Los resultados fueron analizados y descritos en la unidad temática. Las tres unidades temáticas elaboradas son: el proceso de evaluación permite una evaluación fiable del conocimiento - aprendizaje de los estudiantes; el proceso de evaluación permite una reflexión crítica sobre las cuestiones; la forma de evaluación requiere un mayor compromiso de los estudiantes. La percepción de los estudiantes sobre el proceso de evaluación sale al encuentro con las nuevas perspectivas de las directrices curriculares para la graduación en enfermería, especialmente en lo que se refiere a formar profesionales críticos y reflexivos.O presente estudo tem por objetivo a investigar sobre as percepções dos estudantes acerca desta nova forma avaliativa como também o impacto em seu aprender.

    Ferulic acid: a key component in grass lignocellulose recalcitrance to hydrolysis

    In the near future, grasses must provide most of the biomass for the production of renewable fuels. However, grass cell walls are characterized by a large quantity of hydroxycinnamic acids such as ferulic and p-coumaric acids, which are thought to reduce the biomass saccharification. Ferulic acid (FA) binds to lignin, polysaccharides and structural proteins of grass cell walls cross-linking these components. A controlled reduction of FA level or of FA cross-linkages in plants of industrial interest can improve the production of cellulosic ethanol. Here, we review the biosynthesis and roles of FA in cell wall architecture and in grass biomass recalcitrance to enzyme hydrolysis
