UNEXPLORED AND VITAL ASPECTS OF CRYOSURGERY IN DENTISTRY

A better device is the triac, bidirectional thyristor, which allows the full a.c. power to be controlled. It comprises two thyristors connected in parallel and working in opposition but controlled by the same gate. The trigger pulses to a triac are provided by a special device called diac, bidirectional breakdown diode. It is, in effect, two Zener diodes connected back to back. The diac conducts in either direction if the applied voltage reaches the breakdown voltage of about 30 V. This

Dear Students at this level are supposed to have some fundamental knowledge of English grammar. This book helps students to improve their grammar knowledge, expanding their vocabulary, and becoming more confident in following expressing themselves in English.

This study is about people in their formative years. It is about their beliefs and practices. It is about their personality and how it relates to their beliefs. It involves empirical investigation of 1800 college going men (882) and women (918) with an average age of about 20 years. The subjects are predominantly Hindu (85%), with 12% Christian and 3% Muslim student attending colleges in Visakhapatnam urban area. Data were collected from them using the Myers-Briggs Type Indicator (MBTI) and the two specially developed questionnaires that survey religiosity and paranormal beliefs and experiences. Paranormal beliefs and experiences surveyed included sacred as well as secular beliefs, experiences, and practices. While several studies in the West attempted to explore the relationships between personality, paranormal beliefs and religious practices and experiences, there are hardly any investigations in non-Judeo-Christian cultures. The present study can help by throwing light on the cross-cultural relevance of these findings
