Demanda energética nas operações mecanizadas na silagem de milho no sistema de silo bag

Foi avaliado o consumo energético das operações mecanizadas envolvidas na produção de silagem de planta inteira e silagem de grão úmido de milho, tendo como referência o processamento seco desse cereal. O ensaio foi conduzido na Fazenda Experimental Lageado, pertencente à Faculdade de Ciências Agronômicas, e nas instalações da Faculdade de Medicina Veterinária e Zootecnia - UNESP, localizada no município de Botucatu - SP. O delineamento experimental foi em blocos ao acaso, com parcelas subdivididas no tempo (três épocas de colheita: silagem de planta inteira, silagem de grão úmido e colheita de grãos secos), com 10 repetições. As análises estatísticas foram realizadas por meio do programa ESTAT, pelo teste de média de Tukey, a 5% de probabilidade. A silagem de planta inteira teve o maior consumo de combustível por área. A secagem dos grãos de 15,5% para 13% foi responsável por 87% do gasto de energia por área. A silagem de grão úmido demandou o menor uso de energia por área nas operações mecanizadas.

Noncarious Cervical Lesions and Their Association With Toothbrushing Practices: In Vivo Evaluation

Objectives: This pilot study aims to investigate the prevalence of noncarious cervical lesions (NCCLs) in a student population at the Faculty of Dentistry of Aracatuba-UNESP and to assess the potential relation between buccal hygiene habits and the presence and number of NCCLs.Methods: This study was conducted with a sample of 58 young volunteers (15 men and 43 women; mean age, 23.6 +/- 1.8 years and 22.3 +/- 2.4 years, respectively). The research was divided into three steps: 1) clinical assessment; 2) oral-hygiene practices self-report questionnaire; and 3) analysis of toothbrush filament deformations. After the clinical exam the participants were divided into two groups, a control group (without NCCLs) and a test group (NCCLs), according to NCCL presence. The data were statistically analyzed with SPSS 16.0 software, using t-test, chi(2), Fisher exact test, and Spearman correlation.Results: NCCLs were present in 53% of the subjects. The presence of NCCLs was marginally statistically associated with age (p=0.15) and proportionally more prevalent in male (80%) subjects (p=0.01). NCCLs were more concentrated in the posterior-superior quadrant (93%) in both the right (90%) and left (55%) sides of the mouth. The direct rank correlation was presented between presence of NCCLs and toothbrush firmness; and between number of NCCLs and age and force applied during toothbrushing.Conclusion: Within the limitations of this pilot study, the use of medium and hard toothbrushes and greater force applied during toothbrushing might contribute to the development and/or aggravation of NCCLs.

Estudo da contribuição do espalhamento nuclear não elástico na trajetória mais provável de prótons em alvo homogêneo composto de água

The Therapy with proton beam has shown more e ective than Radiotherapy for oncology treatment. However, to its planning use photon beam Computing Tomography that not considers the fundamentals di erences the interaction with the matter between X-rays and Protons. Nowadays, there is a great e ort to develop Tomography with proton beam. In this way it is necessary to know the most likely trajectory of proton beam to image reconstruction. In this work was realized calculus of the most likely trajectory of proton beam in homogeneous target compound with water that was considered the inelastic nuclear interaction. Other calculus was the analytical calculation of lateral de ection of proton beam. In the calculation were utilized programs that use Monte Carlo Method: SRIM 2006 (Stopping and Range of Ions in Matter ), MCNPX (Monte Carlo N-Particle eXtended) v2.50. And to analytical calculation was employed the software Wolfram Mathematica v7.0. We obtained how di erent nuclear reaction models modify the trajectory of proton beam and the comparative between analytical and Monte Carlo method

Sacralità del testo costituzionale ed eresia interpretativa: la sentenza della corte suprema brasiliana sulle unioni civili omosessuali

The paper provides a close lecture of the arguments and methods of legal construction, employed in the extensive individual opinions written by the Justices of the Brazilian Supreme Court in the case which authorized the same sex civil union. After tracing an outline of the legal problem and his possible solutions, we analyze the individual opinions, showing their methodological syncretism, the use of legal methods and arguments in a contradictory way as well the defciencies in the reasoning. The Justices use legal arguments, but do not meet the requirements of rationality in the decision-making. We have a rhetorical attempt that aims to satisfy the public opinion rather than to ofer a comprehensive and coherent solution according the normative elements of the Brazilian Federal Constitution of 1988.
