Influência do herbicida Glifosato (N-Fosfonometil)Glicina) na formação de biomassa da alga Pseudokirchneriella subcapitata (Chlorophyceae)

Herbicides are chemical agents most consumed for agricultural production and of these, glyphosate (N-(phosphonomethyl) glycine) represents more than half of world consumption of non-selective herbicides, use of systemic action and post-emergent. The present study aims to analyze the interference of different concentrations of glyphosate in the development of micro algae, unicellular species Pseudokirchneriella subcapitata, with supplementary analysis of the interference of green algae concentrations in the artificial lake Instituto de Biociências Universidade Estadual Paulista in Rio Claro, SP. To identify the effect of glyphosate on the development of microalgae concentrations: 0.118; 0.236; 0.472; 0.944; 1.888 and 3.776 mg of product (all in rejoinders), maintaining control without glyphosate, were inoculated into flasks containing 150mL of medium culture and 5mL of suspension inoculum levels. Each test was continued for 96 hours in a shaker rotating at 150 rpm at 25 / - 2 ° C and constant light of 3200 lux. At baseline and 48; 72 and 96 hours samples were taken for testing for absorbance. The final dry weight was measured and the tests with P. subcapitata cell number was quantified at the beginning and end of the tests using the Neubauer chamber under optical microscope. For algae of the artificial lake of the diversity of microalgae cells was identified through photographic documentation. The analysis of variance comparing treatments for dry biomass showed no significant differences in the tests with P. subicapitata as for the algae to the lake.The analysis of variance MANOVA showed significant differences between the treatments over time but there was no significant difference between the interactions of treatment for tests with P. subicapitata There were significant differences in the tests with microalgae of the artificial lake. With respect to cell quantification, it was found... (Complete abstract click electronic acces below)

Políticas Públicas de Resíduos Sólidos e a Coleta Seletiva em Regente Feijó - SP

This research was mainly focused on public policy analysis of solid waste, and the National Policy and State Solid Waste, as well as determining the performance of the Blue Green Municipality strategic project in relation to the management of municipal solid waste in Regente Feijó, São Paulo. The objective of this research was to analysis of the consequences of the deployment project of selective collection and integration of recyclable material collectors in an association of collectors, called the Association of Recyclable Material Collectors Rock, held in the city from the year 2008, with effective implementation in 2010. We analyzed the actions of the municipal government since the implementation of selective collection, to the development of the Association. The methodology used was literature concerning the issue; routine field surveys to monitor the activities in the landfill and association of collectors, collecting data from questionnaires appropriate to the research topic. We sought to examine old and new forms of urban solid waste management, the evolution of the historical process of this issue in the city and its social and environmental impacts, and the collectors the main social actors in this process. The complexity that addresses this issue was dealt with in this dynamic study, analyzing all parts involved

Grãos em carbonatos marinhos cretácicos da Bacia Potiguar: formações Ponta do Mel e Jandaíra

This work aims to identify and photograph grains that compose important Cretaceous carbonate units of the Potiguar Basin, represented by the Ponta do Mel and Jandaíra formations (Albian-Campanian). Petrographic investigation of thin sections was essential. The samples studied come from wells and surface samples from the collection UNESPetro – UNESP, Rio Claro. In the Ponta do Mel Formation, the grains consist of ooids, oncoids, peloids and bioclasts. Regarding to the identified bioclasts, the solenoporacean red algae, mollusks (bivalves and gastropods), echinoids, foraminifera, ostracods and worms were the dominant elements. In the Jandaíra Formation, the grains are composed by ooids, peloids and bioclasts, which are represented by green algae, mollusks (bivalves and gastropods), benthic foraminifera miliolids, worms, echinoderms and ostracods. The grains found in the Ponta do Mel Formation are somewhat similar to those found in the Jandaíra Formation, with the exception of calcareous algae. The subsurface material from the Ponta do Mel Formation is derived from the upper part of the unit, representing marine high-energy carbonates, which also contains ooids and Trocholina. The samples of Jandaíra Formation, collected in outcrops, often contain green algae, mollusks and miliolids, and come from inner shelf and lagoon facies previously described
