Secular trend of global drought since 1950

Changes in Global Monsoon Circulations Since 1950

We examined changes in several independent intensity indices of four major tropical monsoonal circulations for the period 1950–1998. These intensity indices included observed land surface precipitation and observed ocean surface pressure in the monsoon regions as well as upperlevel divergence calculated at several standard levels from the NCAR/NCEP reanalysis. These values were averaged seasona...

Mariculture A global analysis of production trends since 1950

Aquaculture is one of the fastest growing global food animal production industries and, according to the United Nations Food and Agriculture Organization (FAO), now accounts for nearly half of global food fish supply. This proportion is anticipated to grow in the coming decades as global capture fisheries continue to stagnate and global demand for seafood continues to rise. As the significance ...

Secular Trend in Portugal

This study of secular trend in Portugal has shown that a positive increment in height occurred in Portuguese 18year-old males between 1904 and 2000, and a secular trend in the age at menarche, towards an earliest age, also took place. Mean height increased 8.93 cm, from 1904 to 2000, when reached 172,13 cm. Besides that, in 2000, statistically significant differences (p ≤ 0.001) among the distr...

Growth variation, final height and secular trend

Growth and body height have always been interesting topics in the public opinion. Particularly the stupendous increase of some 15 to 19 cm in final adult height during the last 150 years in most European countries (the “secular trend”), the concomitant changes in body and head proportions, the tendency towards early onset of sexual maturation, the changes in the age when final height is being r...
