On volterra integral equations on time scales

The purpose of the present paper is to study some properties of solutions of Volterra integral equations on time scales. We generalize to a time scale some known properties concerning continuity and convergence of solutions from the continuous case.

A note on the integral trace form in cyclotomic fields

Let m >= 3 be an integer, zeta(m) is an element of C a primitive mth root of unity, and K-m the cyclotomic field Q(zeta(m)). An explicit description of the integral trace form Tr-Km/Q(x (x) over bar)vertical bar Z[zeta(m)] where (x) over bar is the complex conjugate of x is presented. In the case where m is prime, a procedure for finding the minimum of the form subject to x being a nonzero element of a certain Z- module in Z[zeta(m)] is presented.

Escola de tempo integral: uma análise do processo de implantação na Escola Estadual Carolina Augusta Seraphim. -

No Brasil a educação é um tema delicado, com histórico de índices de reprovação e evasão escolar altos, escolas públicas em condições precárias em muitas regiões e profissionais da área pouco valorizados. As políticas públicas são uma importante ferramenta quando se busca sanar todos estes problemas. Uma proposta que vem sendo implantada no Estado de São Paulo é o das Escolas de Tempo Integral, em que os alunos têm a oportunidade de passar mais tempo na escola, com atividades diferenciadas e um modelo diferente da escola comum. Assim, este trabalho tem como objetivo analisar a proposta do modelo e a implementação do mesmo na Escola Estadual Carolina Augusta Seraphim, localizada em Rio Claro. Para a análise de conteúdo, realizada neste trabalho, foi feito o levantamento de material bibliográfico referente ao tema de Escola de Tempo Integral, principalmente no Estado de São Paulo. Também foram analisados documentos e materiais disponíveis no blog da EE Carolina Augusta Seraphim. Podem ser destacados pontos positivos do Programa, como a dedicação exclusiva da equipe gestora, a valorização dos profissionais envolvidos, a participação mais aproximada da comunidade e família dos alunos, a possibilidade que os estudantes têm de pensar e planejar seu futuro. Existem ainda questões a serem melhor debatidas, analisadas ou até mesmo aprimoradas, devido às particularidades de cada escola e até mesmo inovações tecnológicas que podem ser usadas como ferramentas de ensino. Essas são algumas das questões abordadas e analisadas ao longo do trabalho

O funcionamento de uma escola de ensino integral no município de Rio Claro

EE Prof. Carolina Augusta Seraphim, School of Basic Education Cycle II, located in the municipality of Rio Claro in São Paulo, adopted the new Model School of Integral Education in 2013 from analysis and studies of state and local experiences, as an alternative to the demands of the public. The objective of the study is to characterize the operation of this new teaching model implemented by the Secretary of Education of São Paulo, based on the experiences gained through this school in the city of Rio Claro. This is a documentary research that was grounded on the content analysis of documents relating to the design of the program and the school to be searched. Having the information gathered will be compiled and analyzed using the theoretical framework as bibliographies of authors related to the topic, resulting in discussions about the recovery and casualization of teaching about this new teaching model

Diagnóstico dos casos de aprovação nas disciplinas de cálculo diferencial e integral I e II do curso de licenciatura em química - Unesp de Araraquara

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...

Avaliação microscópica da propriedade biológica e da biocompatibilidade do osso composto e do osso integral de origem bovina

The aim of this study was to evaluate the biological properties and biocompatibility of bovine non-demineralized lyophilized and composite bones implanted in tibiae bone cavities and at the subcutaneous level. Twenty-four rats were used and sacrificed 15 and 45 days later. At the subcutaneous level, after 15 days an inflammatory reaction was seen around biomaterial particles with the presence of giant cells and at 45 days fibrous connective tissue had also developed. No signs of ectopic bone formation were observed at tibiae regions; more bone neoformation was observed at the control group (15 days) with 42.8% of the outer cortex layer against 22.6% at Orthogen and 25% at GenMix groups. At 45 days, correspondent values for bone neoformation were 62.5% at control, 26% at Orthogen, and 35% at GenMix groups, respectively. It can be concluded that both materials tested were biocompatible aiming to bone neoformation by their osteoconductive properties with no ectopic formation sites observed.

A influência da escola de tempo integral sobre a qualidade de vida infantil

This study aims to evaluate the quality of life of students aged 7 to 12 years in two municipal schools in the municipality of Minas Gerais. One offers full-time care to their students with extracurricular activities and other school offers only the normal. We used the questionnaire AUQEI, Autoquestionnaire Qualité de Vie Enfant Image. The questionnaire was administered to 232 children. Through this study, we observed that the proportion of children with a good Quality of Life was higher in school full time (81%), compared to the normal school hours (58%). Therefore, it is concluded that the school offers an extended workday, is set in an area rich able to develop the maximum potential of children and their personal skills, which will reflect positively on their quality of life.

Suco integral de amora (Morus nigra L.) obtido através de prensagem e despolpamento: rendimento e caracterização físico-química

Mulberry (Morus nigra L.) is a fruit with a great potential for technological uses, which could be employed to manufacture of syrups, ice cream, candies, yoghurts, beverages, jam, etc. Only the leaf from mulberry trees is commercially used for silkworm feeding. This tree is cultivated on many agricultural environments such as small rural proprieties and settlements. Small farmers waste a great amount of their production for not knowing about mulberry technology. Thus, the objective of this work was to access extraction yield and physical-chemical properties of mulberry whole juice from ripe, green and a mixture of both by using press and depulper. Statistical analysis of results was carried by media and standard deviation calculations. 173 kg of mulberry were picked being 49.31% ripe and 50.68% green. Press delivered greater extraction yield of whole juice (80.50% to 81.60%) when compared to press (71.43% to 77.50%). Whole juice obtained from both equipments has shown the following values: soluble solids 7.45% - 12.11%, titrable acidity 0.45 – 1.23%, ratio 6.03 – 26.84, pH 3.69 – 4.35, total reducing sugar 4.05% – 9.96%, reducing sugar 3.95% - 9.15%, sucrose 0.00% - 0.04%, turbidity 221.25 NTU - >4,000 NTU. Whole juices obtained from both equipments has shown similar physical-chemical characteristics except turbidity. The authors concluded that press was the best extraction equipment due to its greater yield and whole juice quality regarding turbidity
