Rotaviruses are spherical, double-shelled particles. They have been identified as a major cause of infantile gastroenteritis worldwide. In our earlier studies we determined the three-dimensional structures of double-and single-shelled simian rotavirus embedded in vitreous ice using electron cryomicroscopy and image processing techniques to a resolution of 40Å. A distinctive feature of the rotavirus structure is the presence of 132 large channels spanning across both the shells at all 5- and 6-coordinated positions of a T=13ℓ icosahedral lattice. The outer shell has 60 spikes emanating from its relatively smooth surface. The inner shell, in contrast, exhibits a bristly surface made of 260 morphological units at all local and strict 3-fold axes (Fig.l).The outer shell of rotavirus is made up of two proteins, VP4 and VP7. VP7, a glycoprotein and a neutralization antigen, is the major component. VP4 has been implicated in several important functions such as cell penetration, hemagglutination, neutralization and virulence. From our earlier studies we had proposed that the spikes correspond to VP4 and the rest of the surface is composed of VP7. Our recent structural studies, using the same techniques, with monoclonal antibodies specific to VP4 have established that surface spikes are made up of VP4.

The Brain

A brain tumor is an uncontrolled growth of abnormal brain tissue that can interfere with normal brain function. Although various methods have been developed for brain tumor classification, tumor detection and multiclass classification remain challenging due to the complex characteristics of the brain tumor. Brain tumor detection and classification are one of the most challenging and time-consuming tasks in the processing of medical images. MRI (Magnetic Resonance Imaging) is a visual imaging technique, which provides a information about the soft tissues of the human body, which helps identify the brain tumor. Proper diagnosis can prevent a patient's health to some extent. This paper presents a review of various detection and classification methods for brain tumor classification using image processing techniques.

Field Note

The objectives of this study were to describe the classroom discourse structure, to describe how the classroom discourse is realized by teacher and students and the reasons for the realizations of the ways they are. The source of the data was English teacher and the students while the data are verbal and non verbal utterances of students and teachers. The instruments for collecting data were video tape recorder and researcher’s field note. The data were collected by observing and recording the utterances uttered by the teacher and students. The findings showed that the classroom discourse structures were dominantly realized by Initiation and Response (IR) structure. It was reflected in teacher direct, elicit and information exchanges was found that the classroom discourse structures. The other exchanges occur are boundary (framing and focusing move), directive, informing, check, accept, react, reply, nomination, marker, bid and conclusion acts. The reasons why the realization as the ways they are (1) teacher as a centre of interaction, (2) teacher gives some questions without any caring to the evaluation, appreciation and feedback without any feedback to make dialogue, (3) students have been disciplined not to speak in classes without a teacher’s direction, and most of them are unwilling to speak English.   Keywords: Classroom Discourse Structures, Initiation and Response, Sinclair and Coulthard Theory
