The Spanish registry of alpha-1 antitrypsin deficiency was founded in 1993 and became a member of the International Registry (AIR) in 1999. We describe the updating process following its incorporation into AIR and compare the data collected in the first period (1993-1999) and the second period (1999-2005), during which time patients were included exclusively by internet. The registry included 3...
Whooping Crane (Grus americana) fecal samples were collected from Matagorda Island National Wildlife Refuge (MINWR) during winter and fall of 1993-94 (Winter-1; n = 59), and Aransas National Wildlife Refuge (ANWR) during winter and fall of 1993-94 (n = 102) and 1994-95 (Winter-2; n = 257) to study crane diets and compare patterns of food use in these areas. Food items varied between areas, acro...
The osprey (Pandion haliaetus) population nesting along the main stem Willamette River and lower Santiam River was first studied to evaluate contaminants and reproductive rates in 1993 when 78 occupied nests were present. By 2001, the population increased to 234 occupied nests, a 13.7% annual rate of population increase. A sample egg was collected from each of a series of nests along the Upper ...
This paper is concerned with the estimation of total factor productivity (TFP) growth for the Iranian electric utilities during the period 1980-1993 on the basis of panel data. A translog cost function is used which accommodates firm - specific variability through a one - way error component model. The results show that the Iranian electricity supply industry experienced increasing returns to s...
New results are presented on the fermion asymmetries, Ab and A,, and the b-branching ratio, &, using a data sample of 150,OOOZ” decays collected by the SLD during 1993 and 1994. The fermion asymmetries exploit the highly polarized electron beam available at the SLC (63.0% f 1.1% during 1993 and increasing to a preliminary value of 78.2% f 2.0% during 1994) to perform direct measurements of Ab a...
To test the hypothesis that the intake of psychotropics may increase the risk of hip fracture, a cohort study was conducted upon elderly Korean women. The Korean Elderly Pharmacoepidemiology Cohort was constructed from members of the Korea Medical Insurance Corporation over 65 yr of age who were living in Busan Metropolitan City in 1993.
