Universal relationship between crystallinity and irreversibility field of MgB2

open access: yes, 2005
The relationship between irreversibility field, Hirr, and crystallinity of MgB2 bulks including carbon substituted samples was studied. The Hirr was found to increase with an increase of FWHM of MgB2 (110) peak, which corresponds to distortion of ...

Breakdown by a magnetic field of the superconducting fluctuations in the normal state: A simple phenomenological explanation

open access: yes, 2006
We first summarize our recent observations, through magnetization measurements in different low-Tc superconductors, of a rather sharp disappearance of the superconducting fluctuations in the normal state when the magnetic field approaches Hc2(0), the ...

A Possible Indication of Metallic Iron in White Dwarf Dusty Disks from Their “Dirtiness”

open access: yesThe Astrophysical Journal
Polluted white dwarfs provide unique constraints on the elemental compositions of planetary bodies. The tidal disruption of accreting bodies is thought to form circumstellar dusty disks, whose emission spectra could offer additional insights into the ...

Welfare benchmarking and herd health plans on organic dairy farms (OF0343) [PDF]

open access: yes, 2005
Introduction In response to the recommendations of recent studies on the health and welfare of dairy cattle (Whay et al. 2003) and to assist farmers to meet legislative requirements, promoting farm animal welfare and meeting consumer demand, this study ...

Combustion-engine Temperatures by the Sodium Line-reversal Method [PDF]

open access: yes
The sodium line-reversal method has been used in some preliminary measurements of flame temperature. Improvements in the method involving a photographic recorder and a means of correcting for the dirtiness of the windows are described.

Why observers should train clinical scoring [PDF]

open access: yes, 2010
Epidemiological studies often involve clinical scoring of animals by several observers due to the high number of farms to be visited. Detailed written procedures and intensive observer training minimize variation between observers.

Toxic exposure in America: estimating fetal and infant health outcomes [PDF]

open access: yes
We examine the effect of toxic exposure on U.S. infant and fetal mortality rates between 1989 and 2002 from toxic pollution released by facilities reporting to the Toxic Release Inventory (TRI).
