The concentrations of total airborne bacteria, respirable endotoxins, ammonia, and respirable and inhalable particles were monitored in 160 piggery buildings in Australia between autumn 1997 and autumn 1999. The overall mean airborne bacteria, respirable endotoxins, ammonia (NH3), and inhalable and respirable particle concentrations measured were 1.17 x 10(5) cfu m(-3), 33.1 EU m(-3), 3.7 ppm, ...

This research investigated how the presence, basic features, and match of interface input capabilities to a task domain can either stimulate or impede thinking about science. Students’ hypothesis generation in biology was compared while they used: (1) non-digital paper and pencil tools, (2) a digital paper and pen interface, (3) pen tablet interface, and (4) keyboard-based graphical tablet inte...

The effect of apramycin treatment on transfer and selection of an Escherichia coli strain (E. coli 912) in the intestine of pigs was analyzed through an in vivo experiment. The strain was sequenced and assigned to the sequence type ST101 and serotype O11. It carried resistance genes to apramycin/gentamicin, sulphonamide, tetracycline, hygromycin B, β-lactams and streptomycin [aac(3)-IV, sul2, t...

D-Penicillamine (2-amino-3-mercapto-3-methylbutanoic acid), a well-known heavy metal chelator, is the drug of choice in the treatment of Wilson's disease and is also effective for the treatment of several disorders including rheumatoid arthritis, primary biliary cirrhosis, scleroderma, fibrotic lung diseases and progressive systemic sclerosis. The method proposed incorporates a technique, previ...

Super-shedders, cattle shedding at least 104 colony forming units (CFU) of E. coli O157:H7, elevate risks of contaminating the food chain and maintaining the organism in cattle populations. As detecting supershedders in cattle populations is laborious and time-consuming, a study was conducted to evaluate the role of hide and pen-floor contamination by model super shedders (MSS) in transmission ...

Real-Time Whiteboard Capture System captures whiteboard lecture video in real time and extracts newly written pen strokes. Unlike other systems, it does not require special instruments such as electronic pen or whiteboard. The captured video images are classified into pen strokes on the whiteboard, foreground (person in front of the whiteboard) and Whiteboard Background Model (whiteboard withou...

This study examined competition effects on ADG in the feedlot of 1,882 Hereford bulls representing 8 birth years from a selection experiment. Each year, 8 feedlot pens were used to feed bulls in groups, with 2 pens nested within each of the 4 selection lines. Gains were recorded for up to 8 periods of 28 d. Models for analyses included pen effects (fixed or random), fixed effects such as year a...

Pen computing as afield broadly includes computers and applications in which a pen is the main input device. This field continues to draw a lot of attention from researchers because there are a number qf applications where pen is the most convenient form of input. These include: 1 . Preparrng a f i r s t d r a f t o f a d o c u m e n t a n d concentrating on content creation. 2. A sociallv acce...

BACKGROUND The objective of this study was to characterize how successfully patients with diabetes are able to distinguish between pens of the same pen type containing long- and short-acting insulins. METHODS Structured one-on-one interviews were conducted with 400 patients with diabetes in the United States, using either a differentiated (n = 100) or undifferentiated (n = 100) SoloSTAR® (ins...
