a comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولElectron microscopy of ascus formation in the yeast debaryomyces hansenii.
Ascus formation in Debaryomyces hansenii includes fusion of two cells, usually mother and daughter while still attached to each other, through short protuberances developed from the cross wall between them. Nuclear fusion takes place in the channel connecting the two cells; meiosis apparently occurs in the mother cell. Generally, only one lobe of the meiotic nucleus is surrounded by a prospore ...
متن کاملPhysiological basis for the high salt tolerance of Debaryomyces hansenii.
The effects of KCl, NaCl, and LiCl on the growth of Debaryomyces hansenii, usually considered a halotolerant yeast, and Saccharomyces cerevisiae were compared. KCl and NaCl had similar effects on D. hansenii, indicating that NaCl created only osmotic stress, while LiCl had a specific inhibitory effect, although relatively weaker than in S. cerevisiae. In media with low K+, Na+ was able to subst...
متن کاملCopper-zinc superoxide dismutase from the marine yeast Debaryomyces hansenii.
We have isolated the cytosolic form of Cu-Zn superoxide dismutase (SOD) from the marine yeast Debaryomyces hansenii. This enzyme has a subunit mass of 18 kDa. The preparation was found to be heterogeneous by IF electrophoresis with two pI ranges: 5.14-4.0 and 1.6-1.8. The enzyme preparation had a remarkably strong stability at pH 6.0-7.0, surviving boiling for 10 min without losing more than 60...
متن کاملExtrinsic allergic alveolitis induced by the yeast Debaryomyces hansenii.
A 65-yr-old female developed cough, fever and dyspnoea following repeated exposure to a home ultrasonic humidifier. High-resolution computed tomography showed ground-glass opacity in both lung fields. Arterial blood gas analysis gave an oxygen tension of 8.38 kPa (63 Torr). Pulmonary function testing revealed restrictive ventilatory impairment with a reduction in the diffusing capacity. The dia...
