Abstract: Specimens of Pimelodella captured in the Miranda River, Pantanal of Mato Grosso do Sul State, present morphological features that could indicate at least four species. Therefore, karyotype analysis and molecular biology provided evidence that they were only two species, one showing 2n = 46, and the other, 2n = 52 chromosomes, with only 18% genetic similarity. The morphological analysis evidenced that the dorsal filament is a male characteristic and that the upper lobe of the caudal fin was variable and might or might not be elongated in both species. With respect to morphometric characters, the formation of two groups was evident, but with a small overlap of specimens between them. Among the species with filaments on the dorsal fin observed in the Pantanal, the one with the lesser length of adipose fin base is P. griffini, which corresponds to that with 2n = 46 chromosomes, whereas the species P. taenioptera has 2n = 52 chromosomes. Thus, the accurate detection of these cryptic taxonomic units was only possible with the use of various analysis techniques. Furthermore, it is worth noting that the identification of cryptic species is important for obtaining correct estimates of fish diversity in the Pantanal Exemplares de Pimelodella capturados no rio Miranda, Pantanal do Mato Grosso do Sul, apresentavam características morfológicas que poderiam indicar, pelo menos, quatro espécies. Entretanto, com a análise cariotípica e da biologia molecular ficou evidente que se tratava de apenas duas espécies, uma apresentando 2n = 46 e a outra, 2n = 52 cromossomos, e com apenas 18% de similaridade genética. Pela análise morfológica foi observado que o filamento dorsal é uma característica de machos, e o lobo superior da nadadeira caudal se mostrou variável, podendo, ou n o, ser alongado em ambas espécies. Com rela o aos caracteres morfométricos, também houve a forma o de dois grupos, mas com uma pequena sobreposi o de exemplares entre eles. Das espécies com filamento na nadadeira dorsal apontadas para o Pantanal, a que possui menor comprimento da base da nadadeira adiposa é P. griffini, o que corresponde àquela com 2n = 46 cromossomos e, ao contrário, a espécie com 2n = 52 cromossomos, é P. taenioptera. Assim, apenas com o emprego de diversas técnicas de análise foi possível o reconhecimento seguro dessas unidades taxon micas que se mostravam crípticas. Ressalta-se, ainda, que a identifica o de espécies crípticas é importante para que estimativas da diversidade de peixes do Pantanal sejam feitas corretamente

Abstract: the regularization of flow on low s?o francisco river is related with the dams built in its course. this paper evaluates the magnitude of flow changes caused by building of sobradinho reservoir. it was used permanence curves to level and discharge as tool of analysis. the distance studied was 197 km from the gage station piranhas, al, to the mouth of the river in the atlantic ocean. it was used series of level and discharge of four stations wherein rating curves were corrected through reference levels of the ibge. the building of sobradinho caused a decrease percentual average of 6 to 12% in the greatest water levels (c5) and an increase of 20 to 32% in the smallest water levels (c95). there was a decrease of 9% in the maximum discharge (q5) and an increase of 27% in the minimum discharge (q95). the discharges q5 and q95 were respectively 5,652 and 1,231 m3 s -1 at p?o de a?úcar station for the period after sobradinho. the results show that the regularization of the flow regime after the building of sobradinho minimized the effects of greatest floods in the downstream areas, but the traditional activities of the riverine populations such as fishing, navigation and agriculture has been gradually affected.
Combining Geographic Information Systems for Transportation and Mixed Integer Linear Programming in Facility Location-Allocation Problems  [PDF]
Silvia Maria Santana Mapa, Renato da Silva Lima
Journal of Software Engineering and Applications (JSEA) , 2014, DOI: 10.4236/jsea.2014.710076
Abstract: In this study, we aimed to assess the solution quality for location-allocation problems from facilities generated by the software TransCAD® , a Geographic Information System for Transportation (GIS-T). Such facilities were obtained after using two routines together: Facility Location and Transportation Problem, when compared with optimal solutions from exact mathematical models, based on Mixed Integer Linear Programming (MILP), developed externally for the GIS. The models were applied to three simulations: the first one proposes opening factories and customer allocation in the state of Sao Paulo, Brazil; the second involves a wholesaler and a study of location and allocation of distribution centres for retail customers; and the third one involves the location of day-care centers and allocation of demand (0 - 3 years old children). The results showed that when considering facility capacity, the MILP optimising model presents results up to 37% better than the GIS and proposes different locations to open new facilities.
Air Quality Monitoring and Its Implication on the Environmental Licensing Process in Brazil  [PDF]
José Carlos de Moura Xavier, Wilson Cabral de Sousa Junior
Journal of Environmental Protection (JEP) , 2014, DOI: 10.4236/jep.2014.51001

In the state of Sao Paulo, Brazil, public policies regarding the air quality aimed at the welfare of the population are strongly dependent on monitoring conducted by the Sao Paulo State Environmental Company (CETESB), which can be influenced by faulty monitors and equipment support and cuts in power supply, among others. A research conducted from 1998 to 2008 indicated that a significant portion of the air quality automatic stations in the state of Sao Paulo did not meet the criterion of representativeness of measurements of PM10, NO2, O3, CO and SO2 concentrations which resulted in the classification of some municipalities as the nonattainment area, a situation evidenced for PM10 and O3 parameters. The network unavailability for each parameter was estimated and compared with the monitoring networks operated in Canada and the UK. This paper discusses the implications of the lack of representativeness of measurements in the environmental licensing process of pollution sources from 2008, when by the effect of state law, municipalities have been qualified according to their air quality nonattainment level.

Animal Manure as a Nitrogen Source to Grass  [PDF]
Anderson de Moura Zanine, Daniele de Jesus Ferreira
American Journal of Plant Sciences (AJPS) , 2015, DOI: 10.4236/ajps.2015.67098
Abstract: The use of animal manure has been studied increasingly in recent years due to the excess waste in confinements, which generates great amounts of animal excreta; and as a result of the worsening petroleum crisis, the cost of mineral fertilizing products has increased. Thus, studies point out the potential of this waste to improve biotic and abiotic soil condition and nutritional value of forage. Substances ingested by animals that resist the action of gastric enzymes are enriched with large amounts of bacteria, other microorganisms and other substances to form residual feces, the main component of manure, which, together with the wash water from barnyard urine, form the slurry. The volume of living or dead bacteria in the feces represents 20% of total manure and it is from these that a large amount of nitrogen originates as protein. Due to this potentiality, animal manure can be used as an input in agriculture, impacting positively on production and forage productivity, and having a favorable effect on the environment.
Compromisso governamental e or?amento participativo: estudo comparativo das experiências em Blumenau e Chapecó, Santa Catarina
Moura, Reidy Rolim de;
Revista Katálysis , 2007, DOI: 10.1590/S1414-49802007000200008
Abstract: this article addresses the need for government commitment to participatory budget (pb) experiences, based on a comparison of processes in two municipalities: blumenau and chapecó, santa catarina. the discussion about the construction of democratic public spaces in brazil is reviewed and the factor of government commitment is then emphasized. this is considered an important element to be observed in studying and applying the participative budget. the principal differences in the process of developing the pb in blumenau and chapecó, were analyzed, focusing on this variable and on the ways that political forces respect and attend the deliberations of this participatory process. the study principally used document and field research as well as semi-structured interviews. the results show that in chapecó there was greater government commitment to the pb, which made clear how this can improve the chances for success of this experience.

Abstract: what technology has to offer to education is ever more abundant, creative and reliable. be it in the image technology, in the computers and in their combinations, the possibilities are almost endless. nevertheless, academic schools fail to materialize the benefits one could expect from such resources. while there is ample evidence that well-focused initiatives show positive results on learning, this learning potential does not generalize for educational systems as a whole. school sociology is at odds with the modes of utilization that would make a difference. as a result, students lose. in contrast, computers in students' homes improve learning. even more admirable, non-formal schooling modes have been using technology with ample success.

Abstract: high school is the meeting point of big contradictions in brazilian education system because it plays a lot of roles. we can say that it is a level in permanent crises. the major problem of high school is in having to prepare half of its students to work and the other half to higher education. these two things differ a lot from each other; since there's a big distance between values and functional attitudes concerning both. high school inherits all the problems from the primary school and add them new model in the world. there is no alternate route between schools with different faces (european model); and there isn't any possibility of taking different paths in the same school either (american model). there is a wide debate on the solution to our high school system. some of the big lines can be suggested, principally because they deal with mistakes which corrections are necessary. but, soon, however, it will be necessary to have enough courage to solve the problem concerning the unique system, which in theory, offers the same school to everybody, but in fact, it doesn't offer anything, even a good education. besides that, it still discriminates the poor people. only brazil has this system. only brazil pays the price for this impossible utopia.
