1)The immediate objective of the NPP 2000 is to address the unmet needs for contraception, health care infrastructure, and health personnel, and to provide integrated service delivery for basic reproductive and child health care.Apr 30, 2015
2)Net primary productivity (NPP), which is the residual amount of organic matter produced by vegetation photosynthesis minus its autotrophic respiration consumption, is an important ecological indicator for the status of a terrestrial ecosystem carbon budget [6,7].
3)Occupation structure: The aggregate distribution of occupations in society, classified according to skill level, economic function, or social status.Occupational structure is shaped by factors such as the structure of the economy, technology, bureaucracy, the labour-market, and by status and prestige.
4)An increase in the number of people that reside in a country, state, county, or city. To determine whether there has beenpopulation growth, the following formulais used: (birth rate + immigration) - (death rate + emigration).
5)The sex ratio is the ratio of males to females in a population. In most sexually reproducing species, the ratio tends to be 1:1. This tendency is explained by Fisher's principle. For various reasons, however, many species deviate from anything like an even sex ratio, either periodically or permanently.
Determine the size of the second populationgroup. For example, assume there are 20,000 Hispanics in the total population. Divide the Hispanic population, 20,000, by the Asian population, 10,000, to find the ratio of Hispanics to Asians: 20,000 divided by 10,000 is 2 to 1 -- there are two Hispanics to every Asian.
6)Adolescence is a transitional stage of physical and psychological development that generally occurs during the period from puberty to legal adulthood. Adolescence is usually associated with the teenage years, but its physical, psychological or cultural expressions may begin earlier and end later.
