Studies show that the disciplines of differential and integral calculus have high failure rates in all schools where they are present and, although this problem has been accentuated in recent years, it is not a local phenomenon. It's observed since 1970s in various Institutions of higher education in Brazil. These studies seek to understand the causes of failures and proposals for teaching methodology that aims to help reduce these rates. However, there is a large contingent of students who are successful at the first time that they perform these disciplines. And these cases, although they have not been studied, can contribute greatly to the understanding the aspects that are related to learning of them. And this understanding can lead to attitudes and learning and teaching methodologies that promote the expansion of this success. The fact that these subjects also have high failure rates in the Degree in Chemistry of this Institute, this study aimed to investigate the factors that were relevant to the cases for approval of the students performed for the first time. For this we constructed a questionnaire containing objective questions and open answers. The objective sought to diagnose the profile of these students with regard to age, gender, basic education (elementary and middle school), study habits, concurrent activities, among others. These questions were analyzed using simple statistics. The open-ended questions asked students to indicate that they attribute the success obtained in the disciplines and to suggest modes of study. These questions were analyzed using thematic categorization, a method of content analysis. This questionnaire was completed, voluntarily and without identification, by students who have passed the first time attended the courses Calculus I and/ or Calculus II and had never started another college prior to this. The results indicate that the most relevant factors in this process were dedication and correct habits...

The sheep industry has become increasingly prominent in agribusiness, transforming the stage production of Brazil, and thus contributes more to the socio-economic development of the country. The work aimed to verify the occurrence of brucellosis and leptospirosis in sheep from northwestern São Paulo state. In addition to determining the prevalence of major Leptospira in the region and to trace the diagnosis of sheep breeding in this part of the country. All the 1222 sheep serum samples from 49 properties did not react serologically to evidentiary testing for brucellosis, compared to antigens of B. abortus and B. ovis used in the testing of 2-ME and IDGA, respectively. The Microscopic Agglutination Test (MAT) test revealed that 19.14% (232/1212) of samples were positive for one or more serovars, with titles ranging from 100 to 800. The most frequent serovar was hebdomadis in the region, with Sentot and Sherman (18.10%, 11.64% and 8.62%, respectively). By profiling the system of sheep farming in the region, we found that most herds are composed of more than one race being the main purpose is for the court. According to the scheme adopted immunoprophylactics there is a homogeneous set schedule. It adopts the use of anti-helminth, non-prescription veterinary antibiotic. There is also the presence of diarrhea and abortions and the lack of criteria for los ovinos on management, making it the need for emergency development of programs for disease control, schema immunoprophylactics adequate sanitation and hygienic measures in sheep breeding.

Relata-se um caso de ceratoconjuntivite causada por Encephalitozoon hellem em agapornis (Agapornis spp.) adultos, provenientes de um criatório comercial. Cinco animais apresentaram sinais clínicos de ceratoconjuntivite, blefaroespasmo e blefaroedema bilateral, com presença de secreção seropurulenta. Amostras fecais foram colhidas e foi realizado exame coproparasitológico, com resultado negativo. Dois animais foram necropsiados, sendo detectados, em impressões de raspado de conjuntiva ocular, esporos e outros estádios evolutivos de Microsporidium. A confirmação do diagnóstico foi feita pela reação em cadeia de polimerase e sequenciamento de fragmentos amplificados, com utilização de primers específicos para o gene da subunidade 18S do rRNA de E. hellem. A análise dos fragmentos amplificados demonstrou 100% de similaridade com outras sequências de E. hellem publicadas no GenBank. Este é primeiro relato de infecção por E. hellem em aves no Brasil.

The issue of environmental impacts to human health and the generation and disposal of solid waste has led to a change of paradigms for your face, highlighting the need for sustainable management of municipal solid waste (MSW). In this context, the expansion of landfills in Brazil in recent decades makes it necessary to sustainable management of waste generated by this type of enterprise, since its implementation. The aim of this study was to perform a diagnosis of the generation of waste in a landfill, in the expansion phase, and the alternatives adopted for its management. The qualitative diagnosis was made from observations on site and the wastes were classified and quantified from August 2011 to January 2012. In the diagnosis was considered the reduction, reuse and recycle, in that order. The results of this study showed that the residue of the greatest generation was PEAD geomembranes used in the waterproofing of the landfill, reaching 7 t, followed by PVC pipes, which reached 850 kg, both destined for recycling. The largest volume of wastewater generated corresponded to the leachate, reaching 11,500 m3 , which were sent for treatment

Over the last few years, Brazil has some problems related to the management of solid waste, mainly related to the final disposal of materials, resulting in serious environmental risks to the municipalities that suffer from this type of situation. Poorly designed landfills and weak management systems after the termination of their employment, for example, is currently showing as a major problem for urban expansion and the subsoil of these sites, endangering all the environmental quality of the areas where they are located . Because of this scenario, this work produced a diagnosis of the current situation of the management of solid waste in the city of Rio Claro (SP) from its generation, through selective collection and sorting, as well as its final destination, in order to propose a reflection on current form management, in order to present some guidelines based on Federal Law 12.305 / 2010 - National Solid Waste Policy for improvement of this issue in the city. Although the situation found in the city can be considered reasonable for good, there is a need to improve and how to manage, especially in the operational issue of selective collection and also the participation of society in the category Environmental Education, converging in the search for improvements to the common good

Contexto: O manuscrito descreve o ataque não provocado de um jacaré-do-Pantanal a um pescador. Ataques por jacarés são pouco relatados e a espécie do Pantanal raramente causa acidentes. Descrição do caso: A vítima foi mordida na mão direita quando limpava peixes nas margens do rio Paraguai, por um jacaré de cerca de 1,5 m que saiu debaixo da vegetação aquática. O paciente apresentou dor, secreção purulenta e febre e procurou auxílio médico, apresentando ferimentos perfurocontusos e perfurocortantes e fratura-arrancamento no segundo metacarpiano direito. Após cinco dias de internação, houve significativa regressão do processo inflamatório, quando obteve alta hospitalar para posterior acompanhamento ambulatorial. Discussão: Os acidentes por jacarés podem ser muito graves, devido à dentição e à potência das mandíbulas desses répteis. Embora algumas espécies amazônicas possam predar seres humanos, o jacaré-do-Pantanal não causa mortes, mas mesmo espécimes de pequeno tamanho podem causar lesões graves e infecção secundária importante, como observado no caso. Conclusões: Devido ao potencial traumático e capacidade de inoculação de micro-organismos, as mordidas de jacarés devem ser encaradas como ferimentos de alto risco pelas equipes de saúde.
