Leg problems and resulting mortality can exceed 1% per week in turkey toms starting at approximately 15 wk of age. Dietary supplementation of organic trace minerals (MIN) and 25-hydroxycholecalciferol (HyD) may improve performance, decrease incidence of leg abnormalities, and increase bone strength. Nicholas 85X700 toms were assigned to 4 treatments consisting of a factorial arrangement of 2 co...

The historical total ozone measurements taken with Dobson Spectrophotometer #8 at Longyearbyen, Svalbard, Norway, in the period 1950–1962 have been re-analyzed and homogenized based on the original measurement logs, using updated relevant parameters. In lack of sufficient calibration information, an empirical quality assessment 5 was performed, based on a climatological comparison with ozone me...

In recent years, the risk of health effects caused by the increased exposure to Ultraviolet-B (UVB) due to stratospheric ozone depletion has received wide attention. In the US, there are two ways to accurately measure the UVB. They include: 1) the National Aeronautical and Space Administration (NASA) Nimbus-7 total ozone mapping spectrometer (TOMS), and 2) the United State Department of Agricul...

The meat quality is a result of properties of muscle metabolism and muscle structure at slaughter. Thus, it is a quantitative trait with a large number of genes involved. Moreover, environmental factors are modifying the gene effects at all stages of the ontogenesis. In our approach, we focussed on the expression of a set of genes with potential functions in development and growth of skeletal m...

Once thought to be an infrequent cause of dementia, it is now estimated that FTD is found in 4% of the general dementia population,1 and is present in 20% to 30% of dementia patients younger than 65 years.2,3 This early-onset dementia can initially present in a variety of phenotypes, most commonly as a gradual change in behavior, personality and/or language ability.4 Symp toms may worsen to the...

Remotely sensed spatio-temporal datasets on the order of megabytes to terrabytes are becoming more common. For example, polar-orbiting satellites observe Earth from space, monitoring the Earth’s atmospheric, oceanic, and terrestrial processes, and generate massive amounts of environmental data. The current generation of satellites, such as the National Aeronautic and Space Administration’s (NAS...

Body weight, livability, and feed conversion of a randombred control turkey line (RBC2) started in 1966 at The Ohio State University was compared with that of modern commercial turkeys hatched in 2003 when fed representative 1966- and 2003-type diets from hatch (March 5, 2003) through 196 d of age. Each pen of modern turkeys consisted of 5 birds each of the Nicholas, British United Turkeys of A...

An assimilated data base of total column ozone measurements from satellites has been used to generate a set of indicators describing attributes of the Antarctic ozone hole for the period 1979 to 2003, including (i) daily measures of the area over Antarctica where ozone levels are below 150 DU, below 220 DU, more than 30% below 1979 to 1981 norms, and more than 50% below 1979 to 1981 norms, (ii)...

Society is increasingly concerned about the welfare of animals kept for food production, for this reason, invasive procedures such as toe trimming in turkeys must be studied to assess the corresponding welfare implications and to ensure such procedures are acceptable for continued use. To this end, research was conducted to evaluate the welfare effects of toe trimming on toms raised to 140 d. T...

This paper presents the acados software package, a collection of solvers for fast embedded optimization intended applications. Its interfaces to higher-level languages make it useful quickly designing an optimization-based control algorithm by putting together different algorithmic components that can be readily connected and interchanged. Since core is written on top high-performance linear al...
