This study aimed to evaluate and characterize the chemical properties of soil organic matter under two periodically flooded forest formations on the island of Marambaia, Rio de Janeiro. These formations differ on the degree of soil water saturation, caused by the influence of water table, and in the (F1) formation presents the water table nearer the surface compared to the (F2) formation. Samples were collected in layers from 0.00 to 0.05, 0.05-0.10 and 0.10-0.20 m. The soil properties evaluated were: pH, H+ + Al+ 3, Ca+2, Mg+2, Na+, K+, P, N, total organic carbon (TOC) and base saturation (V%), humin carbon fraction (C-HUM), carbon of humic acid fraction (HAF-C) and fulvic acid fraction carbon (FAF-C). Statistically higher pH values were observed for F1. In F2 there are higher values of Mg+2, P, N and V% value. Correlation was found between the concentrations of Mg+2, N, humic acid and fulvic acid with water table in F1, and water table in F2 with Na+ and K+. Fraction C-HUM was more representative of the total organic carbon, followed by C-HAF and C-FAF. The TOC levels were higher in F1. The C /N ratio was lower in F2, with values ranging between 9 and 12, and F1 were found higher values of this relationship, ranging from 9 to 15. Among the pathways of formation of organic soils in both areas it appears that the major route for organic matter accumulation is the inheritance route.

The usability and accessibility, when applied to digital information environments, provide ease of use and access to information, respectively. Thus, we aim to discuss these concepts and apply them in specific digital environments to the elderly through the documentary and bibliographic study of specific recommendations on projects for elderly users. This study was conducted in conjunction with students at the Universidade Aberta à Terceira Idade (UNATI) - UNESP - Marilia, who assisted in the classification of recommendations for usability and accessibility are essential (Priority 1), important (Priority 2) and optional (Priority 3). The results indicate the importance of this type of study for the digital and social inclusion of older people by facilitating elements of access and use of information, providing the building more inclusive informational architectures. The resulting recommendations can be used as a starting point for the design of digital environments for the elderly in a specific heuristic evaluation, for example. However, it remains important to the application of usability testing with users, including the application to validate these recommendations, since different contexts may arise from the implementation of different elements, resources and information services.

Trabalho trata da síntese e caracterização de quelatos inéditos de prata, paládio e platina contendo proteínas hidrolisadas da clara de ovo. A ideia consiste em preparar e utilizar quelatos metálicos contendo ligantes de origem natural, como metalofármacos. A pesquisa realizada pode ser dividida em três etapas. A primeira, referente à hidrólise e análise do hidrolisado proteico da clara de ovo. Diversos métodos e condições experimentais foram testadas a fim de se encontrar as condições de hidrólise mais adequadas (natureza da enzima, tempo, pH, temperatura, relação enzima:substrato) para a obtenção de aminoácidos livres e/ou pequenos peptídeos. A segunda parte consistiu na obtenção de compostos de coordenação de platina, prata e paládio contendo o hidrolisado proteico. Nessa etapa, diferentes rotas sintéticas e condições experimentais também foram utilizadas. Além disso, a espectroscopia vibracional no infravermelho foi utilizada nessa etapa para investigar as características estruturais (particularmente, os grupos funcionais presentes) dos compostos metálicos obtidos bem como da matéria prima utilizada (clara de ovo). Após inúmeras tentativas de síntese, três amostras promissoras, do ponto de vista da Química de Coordenação, foram obtidas, a saber, CO-Pd2, CO-Pd9 e CO-Ag3. Ensaios biológicos preliminares, que consistiu na terceira e última parte deste trabalho, foram realizados no sentido de avaliar a capacidade inibitória de crescimento das bactérias S. aureus e E. coli, através da determinação da Concentração Inibitória Mínima (CIM) dos compostos metálicos obtidos.

Introduction: Tuberculosis (TB) is a granulomatous disease caused by Mycobacterium tuberculosis. The genus Mycobacteriumhas two different complexes: M. tuberculosis Complex and M. avium Complex. This is a global health epidemic and remains a major global health problem, besides, the clinical severity of TB is significantly higher in transplanted patients. The detection of these mycobacteria complexes in transplanted patients, by molecular methods, is fundamental for quick treatment of patients and can contribute for rapid and accuracy of diagnosis. Objective: To detect mycobacteria DNA of M. tuberculosis and M. avium Complexes in formalin fixed paraffin-embedded samples (FFPE) of two patients groups: non transplanted and transplanted. Materials and Methods: The study includes 40 FFPE biopsies separated in four groups: NTP – presence of epithelioid granuloma and positive ZN, non-transplanted patients – 9 samples; NTN - presence of epithelioid granuloma and negative ZN, non-transplanted patients – 10 samples; TP – positive ZN, transplanted patients – 9 samples; TN – negative ZN, transplanted patients – 7 samples. Sections were cut for DNA extraction. Samples were submitted to PCR for amplification of: a) β-actin, b) IS6110 insertion and c) IS1245 insertion. DNA evaluation was made by spectrophotometry and efficiency and PCR analysis was made by agarose gels under UV light. Results: In all samples processed, 97.1% were positive for human β-actin gene. In22.2% of NTP group were found the IS6110 insertion sequencebut the IS1245 wasn´t. In the NTN group was not found any sequence. In theTP group, 11.1% of the samples were positive for IS6110 and also 11,1% werepositive for IS1245. In the TN group, 14.3% of the samples were positive forIS6110 and for IS1245, 14.3% was also positive. Conclusion: Although factors such as DNA degradation after formalin fixation and paraffin embedding, were possible to detect DNA from the human gene ...

The civil construction in Brazil has grown a lotover the last years. This has caused a greater competition between companies of the sector. A little difference in quality in service or product a company offers can determine their success in the market. There is a growing demand for tools that optimize processes and bring greater quality to each activity in these companies. Performance measurement systems make it possible to control process efficiency and effectiveness using performance indicators. Considering this need, the paper before you has the objective of creating basic guidelines to introduce performance measurement systems inbuilding installations project companies. A theoretical reference is presented to describe organizational aspects of project companies along with performance measurement systems characteristics. Using a qualitative research methodology, a study case was executed with interviews, observation and document analysis as evidence sources. In the study case, limitations where identified, such as, high degree of product and process flexibility, dependence on subjective analysis for decision making and lack of specialized information systems. Considering the theoretical reference and the study case,the proposed guidelines intend to ease and guarantee greater chances of success when implanting one of these systems

A extensão é compreendida como uma interação entre a Universidade e a comunidade na qual está inserida e como uma via de mão dupla onde a Universidade leva conhecimentos e/ou assistência à comunidade e recebe dela influxos positivos e reais necessidades, ou seja, constitui-se uma relação de troca de conhecimentos. As atividades de extensão desenvolvidas no Instituto de Biociências (IB) da UNESP - Campus Botucatu, por meio de projetos, são diversificadas quanto ao público alvo, quanto ao local de realização e também quanto aos objetivos. Ao longo dos anos, foram realizadas inúmeras atividades de extensão dirigidas aos professores e alunos das escolas de ensino básico, das quais destacamos os projetos de extensão relacionados ao ensino de Ciências e Biologia. Este estudo teve por objetivos identificar as atividades de extensão, desenvolvidas por docentes do IB, voltadas ao ensino básico, e investigar a percepção dos docentes sobre a articulação entre Universidade e escolas de ensino infantil, fundamental e médio. Os dados foram coletados por meio de análise de documentos, questionário e entrevista. Pela análise de documentos, foram identificados os projetos de extensão relacionados ao ensino de Ciências e Biologia e que possuem relação (direta ou indireta) com escolas do ensino básico desenvolvidos pelo IB nos anos 2006, 2007 e 2008, cadastrados na PROEX, vinculados ao Núcleo de Ensino, ao Programa Ciência Na UNESP e ao NADi - Museu Escola.
