1. Percutaneous and endoscopic combined treatment of bladder and renal lithiasis in mitrofanoff conduit
ABSTRACT Introduction and Objectives: Treatment of bulky lithiasis in continent and non-continent urine storage reservoirs has been widely described and debated (1). Less is known about the optimal treatment in patients with a Mitrofanoff conduit. If voiding in these patients is incomplete, leading to recurrent symptomatic bacteriuria, formation of large li

2. LABORATORY INVESTIGATION OF X-RAY PHOTOLYSIS OF METHANOL ICE AND ITS IMPLICATION ON ASTROPHYSICAL ENVIRONMENTS
Methanol (CH3OH) is one of the most abundant organic molecules in astrophysical environments. It has been found in cold regions such as surfaces of comets, ices near young stellar objects and protoplanetary disks, as well as in the gas phase in different regions in space. In this work, we experimentally simulate the methanol ice and its behavior when irradia

3. Tomato seed image analysis during the maturation
Resumo: O potencial fisiológico das sementes está diretamente relacionado à normalidade do processo de formação delas, sob ponto de vista morfológico, estrutural e funcional. Deste modo, o objetivo deste trabalho foi avaliar a morfologia interna de sementes de tomate, híbrido BRS Nagai, em diferentes estádios de maturação, por meio da análise de i

4. UV induced surface modification on improving the cytocompatibility of metallocene polyethylene
ABSTRACT Demand for medical implants is rising day by day as the world becomes the place for more diseased and older people. Accordingly, in this research, metallocene polyethylene (mPE), a commonly used polymer was treated with UV rays for improving its biocompatibility. Scanning electron microscopy (SEM) images confirmed the formation of crests and troughs

5. Influence of Anodization Parameters in the TiO2 Nanotubes Formation on Ti-7.5Mo Alloy Surface for Biomedical Application
In this study, the effects of the parameters such as applied potential difference, time and annealing temperature in the titania nanotubes formation were evaluated. The morphology of the nanotubes was evaluted by using Field Emission Gun - Scanning Electron Microscope (FEG-SEM), Atomic Force Microscope (AFM), contact angle and X-rays diffraction (XRD). Self-

6. Early Devonian (Late Emsian) shark fin remains (Chondrichthyes) from the Paraná Basin, southern Brazil
ABSTRACT We report on the pioneering discovery of Devonian fish remains in the Paraná Basin, which represents the southernmost record of fishes from that period in mainland South America. The material comes from an outcrop at the lower portion of the São Domingos Formation, within Sequence C of the Paraná-Apucarana sub-basin in Tibagi, State of Paraná. M

7. New Flexible and Transparent Solution-Based Germanium-Sulfide Polymeric Materials
New flexible and transparent materials based on germanium sulfide were obtained using GeCl4 and 1,3-propanedithiol as precursors. These materials have transparency in the ultraviolet-visible (UV-Vis) spectral region (about 70%), thermal stability up to 200 °C and glass transition located at temperatures below 0 °C (-37 °C, -56 °C and -59 °C) as shown by

8. Geoquímica orgânica aplicada à formação Irati, área de Herval, Rio Grande do Sul (RS), bacia do Paraná / Organic geochemistry applied to Irati formation, Herval area of Rio Grande do Sul, Paraná basin
The current research had the main focus on the geochemical study of a borehole in the Parana Basin at Herval city (RS), aiming to fill some gaps in the organic geochemistry of the Irati Formation. Ten chemical-stratigraphic units were defined from analytical data of Total Organic Carbon (TOC), total sulfur, insoluble residue, gamma-rays, isotopes of organic

9. DENDROECOLOGIA DE Cedrela fissilis (Vell.) NA REGIÃO DE SANTA MARIA, RS / DENDROECOLOGY OF Cedrela fissilis (Vell.) IN THE SANTA MARIA REGION OF RS
Cedrela fissilis (Vell.) is a species that has a considerable growth and a high quality wood, and because of that it is a potential species for native forests management. However, for the proper handling of this species is necessary the knowledge about its self-ecology and its dynamic in the forest. In order to contribute to the advancement of forest managem

10. Influence of the association between simvastatin and demineralized bovine bone matrix on bone repair in rats
Simvastatin, a drug used to lower blood cholesterol, has been reported to have an anabolic effect on bone. The purpose of this study was to evaluate the influence of simvastatin and demineralized bovine bone matrix (DBBM) on the repair of rat calvarial defects. Defects of 5 mm were created in 64 rats, divided into four groups: no local treatment (control); t

11. Variational calculation of low-energy positron life time in Xe atoms
The least-squares variational method (LSVM) is used for determining trial wavefunctions representing low-energy positron-xenon elastic scattering, which are used to determine the positron lifetime. The trial function is taken to depend on several adjustable parameters, and is improved iteratively by increasing the number of terms. The bound state wavefunctio

12. Caracterização do desenvolvimento ontogênico inicial de Anchoviella vaillanti (Steindachner, 1908)
This study aimed to describe morphologically the ontogenetic initial development of the freshwater anchovy, Anchoviella vaillanti, which is endemic to the São Francisco river basin. We analyzed 132 specimens (SL = 1,3-51 mm) obtained from hauls made with a 500 μm mesh conical-cylindrical plankton net in quarterly samplings in different stretches of the
