Situando-a na nova social no debate torno do caráternarrativo ficcional história, argume...

The purpose of the study was to investigate the mineralogical and Heavy Metals (HMs) present in the granite mining soils in Chimakurthy, India. The mineral exploration of mining soils were identified by X-Ray Diffractometer (XRD) pattern analysis. However, the morphological features and quantitative HMs were detected by Scanning Electron Microscopy/Energy Dispersed Spectroscopy (SEM/...

In the present study, pathogenicity of four native strains of Entomopathogenic fungus; Metarhizium anisopliae, was studied against adult stage of Ixodes ricinus. For this purpose a total number of 180 adult ticks were examined in triplicate. Thirty ticks for each strain and negative and positive controls were immersed in 2.4×107 fungal conidia/ml in vitro. Samples were incubated in separate Pet...

Silicone based oil is heated in the boiler of the diffusion pump and the vaporized oil rises in the central tower and streams out of directional flutes directed downward in the pump throat. This allows air molecules to dissolve in the gaseous oil (gas dissolved in gas). As the oil-air mixture cools (due to water cooling coils wrapped around the pump throat) the oil condenses and returns to liqu...

Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), path analysis, and structural equation modeling (SEM) have long histories in clinical research. Although CFA has largely superseded EFA, CFAs of multidimensional constructs typically fail to meet standards of good measurement: goodness of fit, measurement invariance, lack of differential item functioning, and well-differe...

Correlative optical microscopy and scanning electron microscopy (SEM) combines two techniques enabling the use both optical and electronic analysis techniques on the same sample. For example, optical techniques, such as fluorescence staining, fluorescence in situ hybridization (FISH) could in principle be used with SEM and energy dispersive spectroscopy (EDS) [1]. Optical microscopy provides ef...

Neuronal and mesodermal cell types are generated in separate cell lineages during the larval development of Caenorhabditis elegans. Here we demonstrate that the gene sem-4 is required in both types of lineages for the normal development of neuronal and mesodermal cell types. The sem-4 gene encodes a protein containing seven zinc finger motifs of the C2H2 class, four of which are arranged in two...

PURPOSE To assess the accuracy of the scanning electron microscopy (SEM) and present alternative approaches to quantify surface roughness based on numerical analysis. SETTING Department of Ophthalmology, Maisonneuve-Rosemont Hospital, University of Montreal, Montreal, Quebec, Canada. DESIGN Experimental study. METHODS Lamellar stromal cuts were performed on human corneas using a femtoseco...
