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) ...
Modeling Alteration Minerals on Mars – Investigating the High Temperature Component
Introduction: Alteration minerals are important indicators of thermochemical environments at the time of their formation – and thus indicators for the potential habitability of a site [1,2]. Therefore, the detection of alteration minerals, especially nontronite [3], on Mars was an important step to understand Mars’ hydrous history. This initial finding was followed by the detection of a wide va...
متن کاملSynthesis and characterization of nanocrystalline CoAPO-5: Structural and morphological analysis by alteration on hydrothermal parameters
Nano-zeolite CoAPO-5 as a member of AFI family, was synthesized via a hydrothermal treatment, and structurally characterized using X-ray diffraction (XRD), scanning electron microscope (SEM), and energy dispersive X-ray analysis (EDAX). The effects of crystallization temperature and time on the structure of these powder products were studied. XRD patterns of the synthesized powders revealed a h...

متن کاملStructural alteration of collagen fibres--spectroscopic and mechanical studies.
Fourier Transform Near Infrared Raman Spectroscopy has been used to monitor the molecular changes of collagen in a tendon subjected to strain. In the Raman spectrum of the unstrained tendon, some protein bands, mainly assigned to collagen, can be observed: amide I (1666 cm-1) and III (1266 and 1248 cm-1) vibrational modes and skeletal (C-C) stretching vibrations (816 and 940 cm-1). The position...
