25. Facile Preparation and Characterization of Nanostructured BiOI microspheres with certain adsorption-photocatalytic properties
A novel adsorbent based nanostructured bismuth oxyiodide (BiOI) microspheres combining the highly effective adsorption and green photocatalytic regeneration were fabricated by a facile and rapid low-temperature chemical bath method. The resultant products were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), energy dispersive spe

26. Wastewater treatment in a pilot-scale submerged membrane bioreactor: study of hydrodynamics under constant operating pressure
Abstract A pilot-scale Submerged Membrane Bioreactor provided with PEI hollow fiber membranes was operated under constant pressure mode in order to evaluate the effects of hydrodynamic conditions on the process performance, such as air flow rate, module packing density and aeration configuration. For the three different air flow rates studied (2, 5 and 8 L/m

27. Macrófitas aquáticas do Parque Estadual de Itaúnas, Espírito Santo, Brasil
Resumo Macrófitas aquáticas são organismos visíveis a olho nu e que apresentam partes fotossinteticamente ativas, permanente a temporariamente submersas ou flutuantes. Dada a relevância ecológica e fisionômica do grupo, este estudo objetivou determinar a riqueza de macrófitas aquáticas do Parque Estadual de Itaúnas, Espírito Santo, Brasil, e suas

28. The Structure and Composition of Corrosion Product Film and its Relation to Corrosion Rate for Carbon Steels in CO2 Saturated Solutions at Different Temperatures
For carbon steels immersed in CO2 saturated solutions at different temperatures, the structure and the composition of corrosion product film formed on the steel surface were studied by scanning electron microscope (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The corrosion rate of the steel was evaluated by potentiodynamic polari

29. Is Ki-67, keratin 16, involucrin, and filaggrin immunostaining sufficient to diagnose inflammatory linear verrucous epidermal nevus? A report of eight cases and a comparison with psoriasis vulgaris
Abstract: Inflammatory linear verrucous epidermal nevus and linear psoriasis are sometimes hard to differentiate clinically and pathologically. Although immunohistochemical expression of keratin 10 (K10), K16, Ki-67, and involucrin may be useful for differentiating both entities, these results have been reported in only a few cases. We collected data from 8

30. Microstructure Evolution of the Mg-5.8 Zn-0.5 Zr-1.0 Yb Alloy During Homogenization
The influence of homogenization treatment on microstructure evolution of Mg-5.8Zn-0.5Zr-1.0Yb (mass fraction, %) alloy was investigated under different annealing temperatures and holding times. Results indicated a severe dendritic segregation in the as-cast ingot. Zn and Yb segregate remarkably at the grain boundary and Zr appears in the form of precipitates

32. USO DE NANOBASTÕES DE OURO PARA O DESENVOLVIMENTO DE AULAS PRÁTICAS DE NANOTECNOLOGIA
A gold nanoparticles functionalization experiment was conducted in a biotechnology summer course at UFOP as a model for the introduction of the laboratory practice in nanotechnology for postgraduate courses in the areas of chemistry and biotechnology. The gold nanorods were synthesized by the seed method and then, functionalized with anti-IL-6 antibodies usi

34. Growth of Li Doped Bismuth Oxide Nanorods and its Electrochemical Performance for the Determination of L-Cysteine
Li doped bismuth oxide nanorods have been prepared using sodium bismuthate and Li acetate. X-ray diffraction (XRD) pattern shows that the nanorods are composed of monoclinic Bi2O4 and cubic LiBi12O18.50 phases. Scanning electron microscopy (SEM) observation shows that the nanorods have the length and diameter of 1-5 µm and 50-350 nm, respectively. The forma

35. Leiomiossarcoma gástrico associado a hérnia de hiato em cão da raça Shar-pei: relato de caso
RESUMO Os tumores do sistema digestório não são comuns na medicina veterinária e as neoplasias de estômago representam menos de 1% de todos os tumores malignos. O leiomiossarcoma é o segundo tumor que mais acomete o trato gastrointestinal de cães, com predisposição para as regiões de jejuno e ceco, mas qualquer porção pode ser afetada, desde o es

36. Subversion of immunoproteasome subunit expression in dengue virus serotype 2-infected HepG2 cells
Abstract: INTRODUCTION: Infection with all serotypes of dengue virus (DV) results in augmented antigen presentation by MHC class I molecules. However, the upregulation of immunoproteasome subunits only results from infection with two serotypes. This study aims to elucidate changes in the expression of immunoproteasome subunits resulting from infection with
