13. Effect of pelvimetric diameters on success of surgery in patients submitted to robot-assisted perineal radical prostatectomy
ABSTRACT Objective: Minimally invasive techniques are used increasingly by virtue of advancements in technology. Surgery for prostate cancer, which has high morbidity, is performed with an increasing momentum based on the successful oncological and functional outcomes as well as cosmetic aspects. Materials and methods: Sixty two patients underwent robot-as

15. Easy Epoxidation of Monoterpenes from Common Starting Materials
Epoxidation of monoterpenes, α-pinene, β-pinene, limonene, α-terpinene, and (R)-carvone was carried out by the in situ production of a peroxyacid rather than direct addition of such an expensive and difficult to handle chemical. Previous reports showed use of metal catalysts with high yields, while methodologies without catalysts at high temperature showe

16. Editorial Comment: Robotic versus other nephroureterectomy techniques: a systematic review and meta-analysis of over 87,000 cases
ABSTRACT Purpose Preoperative computed tomography or magnetic resonance (MR) imaging are commonly used for radiological evaluation of renal cell carcinoma (RCC) before radical nephrectomy or nephron sparing surgery(NSS). This study aimed to assess the role of MRI for predicting postoperative renal function by preoperative estimation of renal parenchymal vo

21. Comportamento magnético de materiais por meio da mecânica estatística
Resumo Um problema importante no estudo de materiais magnéticos é saber como esses sistemas se comportam na presença de um campo magnético externo. A resposta para esse problema está na susceptibilidade magnética. Neste trabalho realizamos uma abordagem estatística das propriedades magnéticas dos materiais levando em consideração suas interações

24. Performance eletrocatalítica frente a nitrito de um filme híbrido de fosfomolibdato e sílica organomodificada
RESUMO Materiais híbridos orgânico-inorgânicos nanoestruturados são produzidos com a finalidade de desenvolver e/ou aprimorar uma propriedade de interesse. Uma forma de obtenção de materiais híbridos é através da imobilização de um componente inorgânico em uma rede de sílica organicamente modificada (ormosil). Neste trabalho, um polioxometalato
