We use data from two satellites and a terrestrial carbon model to quantify the impact of urbanization on the carbon cycle and food production in the US as a result of reduced net primary productivity (NPP). Our results show that urbanization is taking place on the most fertile lands and hence has a disproportionately large overall negative impact on NPP. Urban land transformation in the US has ...

A number of S male-sterile plants from several shrunken-2 inbred lines were crossed initially with an R138-TR inbred line pollinator carrying the nonrestoring genotype for S sterile cytoplasm. One such cross, involving a male-sterile female parent from inbred line M825, produced, unexpectedly, a number of male-fertile F(1) progeny, along with the expected male-sterile off-spring. Pollen records...

India, being an agricultural country analysis of soil texture and water resource plays a vital role in increasing the productivity of crops. The area of study is Vellore district in Tamil Nadu where agriculture is the main occupation. Though it is a fact, most of the land remains uncultivated due to the lack of knowledge of soil and water wealth. This paper proposes a method to analyze the suit...

A child's growth achievement is a useful indicator of his well-being and nutritional status. This can easily be assessed by comparing his growth parameters such as weight, length and head ci rcumference, with norms or standards derived from a relatively healthy population of genetically similar children. Such standards are essential to professionals working with children, for example paediatric...

W E appreciate the comments by Mendes de Leon (2007) regarding the challenges involved in using multilevel models to analyze aging effects in samples of older adults that combine multiple birth cohorts. The core argument in the latter portion of his commentary focuses on the advantages of using continuous, rather than categorical, outcome variables when analyzing aging-related change. We are in...
