2005 MLA Sheep Prize Winner

Routine husbandry procedures, such as castration and tail docking, are known to induce pain and distress in lambs (Grant, 2004; Kent et al., 2001). This raises important welfare concerns and has attracted debate on the acceptability of such practices. The most common method of castration and tail docking involves the application of a rubber ring to the scrotum or tail, usually without anesthesi...

The strain-specific modifier Ssm1 is responsible for the straindependent methylation of particular E. coli gpt-containing transgenic sequences.Here,we identifySsm1as theKRAB-zinc finger (ZF) gene 2610305D13Rik located ondistal chromosome4.Ssm1b is amember of a gene family with an unusual array of three ZFs. Ssm1 family members in C57BL/6 (B6) and DBA/2 (D2) mice have various amino acid changes ...

Protoplanetary Disk Masses in the Young Ngc 2024 Cluster

We present the results from a Submillimeter Array survey of the 887 μm continuum emission from the protoplanetary disks around 95 young stars in the young cluster NGC 2024. Emission was detected from 22 infrared sources, with flux densities from ∼5 to 330 mJy; upper limits (at 3σ) for the other 73 sources range from 3 to 24 mJy. For standard assumptions, the corresponding disk masses range from...

The peculiar circumstellar environment of NGC 2024 - IRS 2

We re-examine the nature of NGC 2024 IRS2 in light of the recent discovery of the late O-type star, IRS2b, located 5′′ from IRS2. Using L-band spectroscopy, we set a lower limit of AV = 27.0 mag on the visual extinction towards IRS2. Arguments based on the nature of the circumstellar material, favor an AV of 31.5 mag. IRS2 is associated with the UCH region G206.543–16.347 and the infrared sou...
