Osteochondrosis (OC) is a developmental orthopedic disease that results from a disruption to normal endochondral ossification in the articular-epiphyseal growth complex. In mammals, the hedgehog pathway and growth factor signaling are essential to this process. Previous studies in yearling horses with OC have shown upregulation of Indian hedgehog and insulin-like...
Yellow starthistle (Centaurea solstitialis L.) is an introduced Asteraceae that has become established on 10 million acres in the Pacific Northwest and California.

With the increased variety and use of lining fabrics, consumers
have become concerned over choices for lining fabrics which have
good serviceability properties. The major purpose of this study was
to secure some information on the physical properties of lining fabrics
to help consumers in the selection of lining fabrics...
To assist with risk-assessment with deepwater and ultra-deepwater prospects for offshore energy extraction as well as provide a useful tool for oil spill response, a spatially-explicit model was developed for comprehensive simulations of a blowout event from the wellhead to final fate and degradation. The Blowout and Spill Occurrence Model...
In recent years, non-renewable and non-biodegradable plastic packaging forms the majority of landfilled waste. These products, mainly made from Polyethylene Tetraphlatate (PET) and other polyolefins, have excellent durability and barrier properties, but take hundreds of years to degrade.
Much focus has been put on developing environmentally friendly alternatives to polyolefins...
The purpose of this study was to collect information on relevant sexuality
