In this work, an activated carbon sample with a high adsorptive performance for the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) was prepared from queen palm endocarp ( Syagrus romanzoffiana ) by pyrolysis process. The presented XRD pattern related to graphite and functional groups such as C–H, C?O, O–H. material particles highly-porous structure, being beneficial adsorption showed remarkab...

The identity, localization and physiological significance of enzymes involved in sugar uptake and accumulation were determined for endocarp tissue of pods of Kentucky Wonder pole beans (Phaseolus vulgaris). An intracellular, alkaline invertase (pH optimum, 8) was assayed in extracted protein, as well as enzymes involved in sucrose synthesis, namely, uridinediphosphate (UDP-glucose pyrophosphory...

this study was done to evaluate the effects of harvest time on some factor of ‘ahmadaqaie’ pistachio nuts in rafsanjan. in three consecutive years (2009-2012) during three stages of friut ripening (40, 70 and 100 percent of hulling), fruit was harvested and physiological and biochemical parameters were measured. the experiments were conducted as randomized complete block design with compound an...

Some conservation units in Brazil border urban areas, like the Catolé and Fernão Velho Environmental Protection Area (EPA) State of Alagoas. In there is habit cultivating plants for landscape purposes, Syagrus coronata (Martius) Beccari (Arecaceae), “Licuri” or “Ouricuri”, a palm tree commonly used ornamentation; native species from Caatinga Atlantic Forest biomes widely explored through time. ...

The Covid-19 pandemic brought several challenges to the educational system with regard continuity of classes in context an Emergency Remote Education (ERE). Among these challenges, we highlight intensification disinterest and low participation students chemistry insufficiency didactic proposals that work School Inclusion (SI), a focus on accessibility for deaf. ERE model lasted 2 (two) years, a...

The Phytocreneae (Icacinaceae) are a tribe of scrambling shrubs and lianas presently distributed in tropical Africa, Madagascar, and Indo-Malesia. We describe the oldest known fossils of this tribe and provide the first recognition of this group in the Neotropical fossil record based on distinctive fruit remains. Palaeophytocrene piggae sp. nov., from the late Paleocene of western North America...

The recovery and conservation of traditional fruit tree cultivars is a necessity that faces a short window of opportunity due to accelerating cultivar erosion. Several efforts to preserve old material took place before the widespread use of molecular markers, but often that material has not been conserved in ex situ germplasm collections. Here we present a case in Spain where a thorough invento...

The puruí Alibertia edulis (Rich.) A. Rich. (Rubiaceae) is a naturally occurring species in the Cerrado biome Brazil; its fruits serve as food for local fauna (birds and mammals) humans. Here, we report on beetle feeding of Minas Gerais (MG). Monthly collections were carried out four trees two areas Cerradão vicinity municipality Monte Carmelo, MG, between September October 2018. These legal re...
