    Notes: Electroreflectance (ER) technique has been used to study the effect of growth temperature and source materials on the electronic energy band and crystal structure of zinc sulfide thin films grown using atomic layer epitaxy (ALE). The samples studied were grown by ALE at 300–500 °C from zinc acetate or zinc chloride and hydrogen sulfide. The ER spectra were measured at room temperature and at 77 K. The crystal structure of polycrystalline ZnS thin films grown from zinc acetate at 300–375 °C is mainly cubic, whereas the ZnS layers grown from zinc chloride at 425–500 °C are predominantly hexagonal. The ER spectra of the latter samples show peaks belonging to the cubic structure, too. The crystal structure of zinc sulfide thin films is found to depend both on growth temperature and on source materials.

    Notes: Abstract  The purpose of this study was to demonstrate the histological effects of amniotic fluid on bone healing in the rabbit fetus. Fetal femurs (n=34) were fractured in the diaphysis and two experimental groups were established. In group A fetuses (n=18), the fracture ends were bathed in amniotic fluid through their unsutured skin wounds. In group B fetuses (n=16), the fracture sites were isolated from amniotic fluid by suturing the wound edges. Nonoperated fetuses were used as control group (n=9). The fetuses were sacrificed on the first, third and seventh postoperative days for histological studies. Histological examination of the specimens was performed to detect inflammation, fibroblastic proliferation, bone cellularity, callus and cartilage formation. The results were compared, using the Fisher exact chi square test criteria, where no statistically significant differences were detected between group A and group B ( P〉0.05).

    Natural and Artificial Radionuclides in Selected Lignites from Istanbul (2000)

    Notes: Abstract The radioactivity levels of Istanbul environs lignites were determined. The gamma-spectrometric technique has been used for the determination of activity levels of naturally occurring radionuclides 235+238U, 228+232Th, 40K, 226Ra and fallout radionuclides 137Cs in lignites taken from 7 different parts of Istanbul. Concentration of 238U, 228+232Th, 40K, 226Ra 137Cs and 235U were found up to 1.6 ppm, 1.7 ppm, 4.9 ppm, 56.8 Bq/kg, 34 Bq/kg, 1.8 Bq/kg, 1.6 Bq/kg, respectively. In addition total alpha- and beta-activity levels in lignite samples were found to be 7.6 and 15 eps, respectively.
