A giant ragweed population from a glyphosate-resistant (GR) soybean field in Mississippi, USA was suspected to be resistant to glyphosate. Greenhouse and laboratory studies were conducted to confirm and quantify the magnitude of glyphosate resistance in a resistant biotype selected from this population and to elucidate possible physiological and molecular mechanisms of glyphosate resistance. Gl...

giant cell glioblastoma is an extremely rare variant of glioblastoma (who grade iv) which is characterized by a predominance of bizarre, multinucleated giant cells. these tumors comprise of 0.8% of brain tumors and up to 5% of glioblastomas. in pediatric age group, these tumors are still uncommon with only around 53 published cases since 1952. here, we report a case of a 12-year old female pati...

In this article, we review the history, current status, physical mechanisms, experimental methods, and applications of nonlinear magneto-optical effects in atomic vapors. We begin by describing the pioneering work of Macaluso and Corbino over a century ago on linear magneto-optical effects (in which the properties of the medium do not depend on the light power) in the vicinity of atomic resonan...

The effects of nanostructuration on the magneto-optic properties of ultrathin monocrystalline iron films grown on MgO ~001! are investigated through the magneto-optic coefficients, which have a linear and quadratic dependence on the magnetization. The photon energy dependence of such magneto-optic coefficients is determined by measuring the relative variations of the reflectivity (DRpp /Rpp) fo...
