postnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
X-ray and optical study of the giant radio quasar 4C+74.26
We present the optical and X-ray study of the radioloud quasar 4C +74.26. The ASCA spectrum is rather complex with indications of a reflection component, a neutral iron line and a warm absorber. The underlying power law has a photon index of Γ = 2.03± 0.09. The soft X-ray flux in 1996 is nearly twice as high as that found in a ROSAT observation in 1993 without apparent spectral changes. The X-r...
متن کاملNear-Infrared Observations of Powerful High-Redshift Radio Galaxies: 4C 40.36 and 4C 39.37 1,2
We present near-infrared imaging and spectroscopic observations of two FR II high-redshift radio galaxies (HzRGs), 4C 40.36 (z = 2.3) and 4C 39.37 (z = 3.2), obtained with the Hubble, Keck, and Hale Telescopes. High resolution images were taken with filters both in and out of strong emission lines, and together with the spectroscopic data, the properties of the line and continuum emissions were...
متن کاملdevelopment of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
