Tooth Loss in Birds 116 Million Years Ago
2014/12/30
RIVERSIDE, Calif. — The absence of teeth or “edentulism” has evolved on multiple occasions within vertebrates including birds, turtles, and a few groups of mammals such as anteaters, baleen whales and...
Circumstellar gas and dust emission and mass loss from evolved stars
Orbiting a star Gas Dust emissions Evolution of stars
2014/12/9
This dissertation presents a study of the circumstellar gas and dust emission and their relation to the mass-loss in evolved stars. Considering the physical process of heating and cooling of the dust,...

NEW YORK, NY (January 22, 2014) — Columbia University Medical Center (CUMC) researchers have identified a gene, called matrix metalloproteinase-9 (MMP-9), that appears to play a major role in motor ne...
Assessment of Soil Loss of the Dhalai River Basin, Tripura, India Using USLE
Soil Erosion USLE Rainfall Erosivity Predicted Soil Loss
2013/3/11
Soil erosion is one of the most important environmental problems, and it remains as a major threat to the land use of hilly regions of Tripura. The present study aims at estimating potential and actua...
An extension of solutions to convolution equations with the loss of smoothness
Homogeneous convolution equations mean periodic functions zeros of entire functions
2012/6/19
In the present paper the smoothness loss of an extension of solutions to convolution equations is studied. Also examples for some kinds of convolvers are given.
Watershed land use and river engineering drive wetland formation and loss in the Mississippi River birdfoot delta
Watershed land river engineering drive wetland ation loss the Mississippi River birdfoot delta
2014/4/2
The Mississippi River basin was developed for agriculture at an unprecedented scale and intensity within the last 200 yr. These changes favored erosion and sediment transport, which were subsequently ...
In this work we analyze principle component analysis (PCA) as a deterministic input-output system. We show that the relative information loss induced by reducing the dimensionality of the data after p...
Effectiveness of polymers on improving the fluid loss of Bentonite used in geosynthetic clay liners
Effectiveness polymers improving fluid loss Bentonite used geosynthetic clay liners
2012/3/30
Geosynthetic clay liners (GCLs) are generally used in engineering projects due to their low hydraulic conductivity with water. The bentonite component contributes hydration-induced swelling and impart...
