Septal Q wave vectors. a tiny negative deflection in one or several of the left lateral leads. This initial negative deflection, or Q wave, may therefore be seen in leads I, AVL, V5, and V6. Sometimes, small Q waves may also be seen in the inferior leads and in V3 and V4.
The year 1921 is a year of the great divide in the demographic history of India when mortality started to decline leading to acceleration in the rate of population growth.During the next three decades (1921-51) the rate of population growth continued at a level of over one per cent per annum.. High rate of birth and Low rate of deaths-High population growth (developing). 3. Low rate of birth and Low rate of deaths-Low population growth (developed). In a country like India, where the children are considered as assets, rate of birth tend to be high.
density of population in India is 324 persons per square kilometre. Over the last 100 years density has increased more than four times. It has increased from 77 in 1901 to 324 in 2001. When we say that the density of population of India is 324 persons per square kilometre, this does not mean that population is exactly 324 persons in each and every square kilometre. In reality, the distribution of population in India is highly uneven. The uneven density of population in India is clear from the fact that in Arunachal Pradesh the average number of population is only 13 persons per square kilometre, whereas it is 9,294 persons per square kilometre in Delhi as per 2001 census.
