Abstract The parapharyngeal space (PPS) has a special anatomical and clinical importance from the point of view its content, communication vicinity with major vital structures. Tumors are uncommon, most incriminated being salivary gland tumors, neurogenic especially Schwannomas paragangliomas, lymphoreticular lesions. correct diagnosis PPS tumors must include radiologic evaluation represented b...

O presente estudo teve como objetivo a produção de biossurfactantes por Pseudomonas fluorescens ATCC 13525, utilizando-se única fonte Carbono um resíduo da indústria canavieira, o melaço. Diferentes concentrações melaço e tempos fermentação foram avaliados. A foi monitorada meio tensão superficial, concentração ramnose índice emulsificação (IE 24h). Os resultados mostraram máxima ocorreu em 30h...

We investigate the behaviour of galaxy clustering on large scales using the PSCz catalogue. In particular, we ask whether there is any evidence of large-scale fractal behaviour in this catalogue. We find the correlation dimension in this survey varies with scale, consistent with other analyses. For example, our results on small and intermediate scales are consistent those obtained from the QDOT...

A gas diffusion sequential injection system for spectrophotometric determination of free chlorine is described. The detection is based in the colorimetric reaction between free chlorine and a low toxicity reagent o-dianisidine. A gas diffusion unit is used to isolate free chlorine from the sample in order to avoid possible interferences. This feature results from the conversion of free chlorine...

In the assessment of the quality of surface waters, the typical procedure is that the concentration of contaminants in the surface water is monitored and subsequently compared with their respective Maximum Permissible Concentrations (MPCs). If the MPCs are not exceeded the water quality is considered to be safe. But can we be certain that this is true? We compared MPCs to observed and calculate...

Artemisin traditionally cleave the peroxide bond by Fe(II) found in heme proteins, thus generating toxic oxygen radicals. Synthetic peroxides, thus are proving to be useful substitutes for artemisinin. The first-generation ozonide OZ277, known as arterolane [1], has been found to inhibit the growth of chloroquine-resistant (K1) and chloroquine sensitive (NF54) parasite strains. In 2012, the com...

We present near-infrared VLT-UT1+ISAAC spec-troscopy of a sample of 9 extremely red galaxies (ERGs) with R − K > 5 and K < 19.0. Neither strong emission lines (F lim <1–5×10 −16 erg s −1 cm −2) nor continuum breaks are detected. From near-infrared spectrophotometry, complemented with broad-band optical and near-IR photometry, we estimate " spectro-photometric " redshifts to be in the range of 0...

This paper presents results of statistical calculations of single-particle characteristics of nuclei, excitation energies and shape transition in the Sn isotope with neutron number 50, which is the extremely neutron deficient isotope. It is a very rare and unstable isotope which does not occur in nature, but only on the surface of exploding stars for less than a second. The spherical nucleus at...

Adenocalymma bracteatum is a shrub of dense foliage and yellow flowers, easily found on grasslands areas in Central Brazil. The aim of this study was to determine the reproductive biology and the flower visitors of A. bracteatum in a pasture area nearby Ivinhema city, MS (Brazil). The flowering peak occurs in winter. The flower reflects ultraviolet light. Anthesis begins at 6:30h, and pollen an...
