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) ...
Preparation and NMR, Mass and Mössbauer Studies of Di-and Triorganotin (IV) Derivatives of 3-(2-Furanyl)-2- Propenoic Acid
3-(2-Furanyl)-2-propenoic acid has been used to prepare a new series of organotin complexes of general formula R3SnL (R=Me, Et, n-Bu, Ph and Cy) and R2SnL2 (R=Me and n-Bu). These complexes have been characterized by elemental analyses, IR, 1H-NMR, MASS and Mössbaure spectroscopy.
متن کاملSynthesis , structural characterization and biological studies of copper complexes with 2 - aminobenzothiazole derivatives
Novel copper complexes of 2-aminobenzothiazole derivatives were synthesized by the condensation of knoevengal condensate acetoacetanilide (obtained from substituted benzaldehydes and acetoacetanilide) and 2-aminobenzothiazole. They were thoroughly characterized by elemental analysis, IR, H-NMR, UV-Vis., molar conductance, magnetic moment and electrochemical studies. The UV-Vis., spectral study ...
متن کاملThe Structural, Morphological, Optical and Photoluminescence Studies of Mn2+ Doped CdS/Zn3(PO4)2 Nanocomposites
The present study used a hydrothermal technique to synthesize undoped and Mn 2+ doped CdS/Zn 3 (PO 4 ) 2 semiconducting nanocomposite materials. Powder X-ray diffraction, scanning electron microscopy, UV-Vis diffuse reflectance spectrometer, Fourier transform- Infrared Spectroscopy-FT-IR, and photoluminescence techniques were employed to study structural, optical, and luminescence propertie...
متن کاملStructural Characteristics and Reactivity Relationship of some Thiophene Derivatives
ABSTRACT The application of many hetero-aromatic compounds in pharmaceutical and dye industries make the theoretical study of their dipole moment (µ) oscillator strength (f) and other photo-physical properties worthwhile. These properties determine the solubility of many compounds; predict the relationship between their structures, properties and performance. The f, µ, α, transition dipole mome...
