    Barium tungstate films with different Dy3+ doping concentrations, namely 0 wt.%, 1 wt.%, 3 wt.% and 5 wt.%, are deposited on cleaned quartz substrate by radio frequency magnetron sputtering technique and the prepared films are annealed at a temperature of 700{deg}C. The structural, morphological and optical properties of the annealed films are studied using techniques such as x-ray diffraction (XRD), micro-Raman spectroscopy, field emission scanning electron microscopy, atomic force microscopy and photoluminescence spectroscopy. XRD analysis shows that all the films are well-crystallized in nature with a monoclinic barium tungstate phase. The presence of characteristic modes of the tungstate group in the Raman spectra supports the formation of the barium tungstate phase in the films. Scanning electron microscopic images of the films present a uniform dense distribution of well-defined grains with different sizes. All the doped films present a broad emission in the 390-500 nm region and its intensity increases up to 3 wt.% and thereafter decreases due to usual concentration quenching

    Radio frequency (RF) magnetron sputtered silver incorporated indium oxide thin films were prepared and their structural and morphological properties were studied using micro- Raman spectroscopy, Atomic Force Microscopy (AFM), Field Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive Spectroscopy (EDS). Raman modes corresponding to the cubic bixbyite phase of indium oxide were obtained through micro-Raman spectroscopy. AFM images exhibited dense distribution of grains. Elemental analysis using EDS spectra confirmed the presence of indium, silver and oxygen in the prepared films

Comparing two control kidneys with one CSFK by multiplying the demonstrated number found in control kidney by 2 would yield a total glomerular number of 3,072,604+/−1,077,619 for controls and 2,301,441+/−330,670 for CSFKs (p = 0.10).</p

    <p>A. Comparison between number of glomeruli and cortex volume per kidney of congenital solitary functioning kidneys (CSFKs, closed circles) and control kidneys (open circles) at 26 weeks of age with regression line for control kidneys (solid line, R = 0.697, P = 0.082). B. Comparison between number of glomeruli and cortex volume per pig at 26 weeks of age. Pigs with a CSFK are depicted by closed circles, and control pigs by open circles. Values for control pigs are extrapolated from one to two kidneys. Regression lines are shown for control kidneys (solid line, R = 0.697, P = 0.082) and for controls as CSFKs together (dotted line, R = 0.577, P = 0.31). C. Comparison between median number of glomeruli per mm<sup>3</sup> in CSFKs and control kidneys. Median number of glomeruli per mm<sup>3</sup> in CSFKs was 8.95 (range 6.39–10.42) and in control kidneys 11.46 (range 5.97–13.34).</p
