Introdouction:Tooth eruption is recognized as an important aspect of human growth and development. It can be influenced by a number of factors, and it may reflect the general development of a child’s body. The purpose of this study was to determine the age at which the first primary tooth erupted and its relationship with height, weight and head circumference in 3-15-month children in the...

High quality water is less available for agriculture and thus farmers often use saline water, that affects crop growth and yield. Snap bean (Phaseolus vulgaris) is sensitive to soil and water salinity, and also to heat stress. The aim of this research is to evaluate if a postponed transplant (high temperature stress) of snap bean can influence growth and yield under saline conditions. Snap bean...

This paper estimates income gap ratios and Gini coefficients of poor Americans and combines them with official U.S. government poverty statistics to create a new time series of Sen indices of poverty. The effects of growth and other determinants of aggregate poverty are investigated over the period 1961-1996. The results indicate that economic growth affects the Sen index and official poverty h...

Fixed operating costs draw a sharp distinction between endogenous growth based on horizontal and vertical innovation: a larger number of product lines puts pressure on an economy’s resources; greater productivity of existing product lines does not. Consequently, the only plausible engine of endogenous growth is vertical innovation whereby progress along the quality or cost ladder does not requi...
