Induced mutation study was carried out to study effect of chemical and physical mutagens on different morphological characteristics in the Brassica napus L. cv. Excel. Physiologically similar and uniform size seeds of Brassica napus L. cv. Excel weretreated with different doses of chemical Ethyl methane sulphonate (EMS) and Sodium azide (SA) andphysical mutagen (gamma radiations). Dry and pre-s...

A very novel phenomenon of morphological variations of cadmium sulfide (CdS) nanorods under the transmission electron microscopy (TEM) beam was observed without structural phase transformation. Environmentally stable and highly crystalline CdS nanorods have been obtained via a chemical bath method. The energy of the TEM beam is believed to have a significant influence on CdS nanorods and may me...

The morphological features of a series of 37 specimens of pulmonary atresia with intact ventricular septum were reviewed with particular emphasis on features which might influence the results of pulmonary valvotomy. The degree of right heart hypoplasia was quantified by measuring right and left heart dimensions and comparing them with 20 normal infant hearts. Right ventricular cavity size was u...

We have investigated the properties of strain-compensated InGaAsP/InGaP superlattices, grown by metalorganic vapor phase epitaxy, with and without InP interlayers inserted in the InGaP barrier. Using cross-sectional scanning tunneling microscopy and spectroscopy, we observe lateral variations in layer thickness and electronic properties. When the number of superlattice periods is increased from...

The hand is a prehensile organ, it is endowed with grasping and precision movements for skilled work and it acts as a chief tactile apparatus. Thus human hand is a revolution in evolution. Indeed the lumbricals of the hand by producing flexion at the metacarpophalangeal joints and extension at the interphalangeal joints helps in writing, stitching and any other forms of precision work. A study ...

Address for Correspondence: Dr. Y. Mamatha, Associate professor, Kodagu Institute of Medical Sciences, Madikeri, Karnataka State, India. E-Mail: [email protected] Background: The lungs are the essential organs of respiration. Fissures are an integral part of human lung. The fissures in lung enhance uniform expansion. These fissures may be complete, incomplete or absent. A detailed knowledge o...

Most commonly occurring predacious fungus Arthrobotrys oligospora showed great variation in size and shape of conidia on some media. The formation of larger conidia was recorded on beef extract and nutrient agar media. The length of conidia in Richard's YPSS, Sabouraud's, PDA and corn meal agar media was of medium size while smaller conidia were produced on Czapek's, Jensen's, Martin's medium. ...
