A bioassay of 2-aminoanthraquinone for possible carcinogenicity was conducted using Fischer 344 rats and B6C3F1 mice. 2-Aminoanthraquinone was administered in the feed, at either of two concentrations (except for female rats), to groups of 50 male and 50 female animals of each species. The time-weighted average dietary concentrations used in the chronic bioassay were 0.69 and 0.35 percent for h...

introduction the experts believe that the entrepreneurs are powerful engines of economic growth and producing wealth, and crucial for improving the quality, number and variety of employment opportunities for the poor people as well as the villagers. in this situation, one of the best solutions for unemployment and progress of economic base of villagers is developing small scale businesses in ru...

Mobile devices have found an important place in modern society, with hundreds of millions currently in use. The majority of these use inherently weak authentication mechanisms, based upon passwords and PINs, which can potentially be compromised and thereby allow attackers access to the device and its stored data. A need for stronger authentication is identified and the discussion considers the ...

BACKGROUND Aboriginal and Torres Strait Islander families experience markedly worse maternal and child health outcomes than non-Aboriginal families. The objective of this study was to investigate the experiences of women attending Aboriginal Family Birthing Program services in South Australia compared with women attending mainstream public antenatal care. METHOD Population-based survey of mot...

We consider a multitype branching process with immigration in a random environment introduced by Key in [Ann. Probab. 15 (1987) 344–353]. It was shown by Key that, under the assumptions made in [Ann. Probab. 15 (1987) 344–353], the branching process is subcritical in the sense that it converges to a proper limit law. We complement this result by a strong law of large numbers and a central limit...

An interpenetrating polymer network (IPN) is any material containing two polymers, each in network form. An IPN is a combination of at least two polymers, and IPN can produce synergistic effect by sharing the properties of both the polymers consequently avoiding the limitations of natural as well as synthetic polymers. The present review discusses various types of IPN. Various methods of prepar...

An experiment was carried out to determine the effect of corn silage particle size and fat supplements on performance, solid passage rate through the digestive tract, and chewing behavior in dairy cows. The forages were coarse or fine corn silage with geometric means of 8.8±2.7 and 5.6±2.8 mm, and alfalfa with geometrics means of 7.0±3.3 mm, and fat supplements were neutral fat (palm) and soy-o...
