Flint corn has a greater proportion of vitreous endosperm than dent corn (Philippeau et al, 1999). Philippeau and Michalet-Doureau (1997) observed that increased kernel vitreousness was associated with decreased ruminal starch degradation. Increased kernel vitreousness may explain the reduction in total-tract starch digestibility observed for mature whole-plant corn silage (WPCS; Bal et al., 19...

al., 1999), caused by environmental toxins or drug administration (Abd-Allah et al., 1999; Puhakka et al., 2002) and some nutritional deficiencies (Giovannelli et al., 2002; Szete et al., 2002; White et al., 2002; Kapiszewska et al., 2005a). It was shown that the comet assay used to study single/double strand breaks and oxidative modifications in the DNA bases was sensitive enough to detect als...

The spatial arrangement of plants in a landscape influences wind flow, but the extent that differences in the density of conspecifics and the height of surrounding vegetation influence population spread rates of wind dispersed plants is unknown. Wind speeds were measured at the capitulum level in conspecific arrays of different sizes and densities in high and low surrounding vegetation to deter...

In 1972, Crawford and Sinclair published evidence that AA and DHA were independent determinants of brain growth and evolution [Crawford and Sinclair 1972; Broadhurst et al., 2002; Enard et al., 2002; Pennisi 2002]. Deficiency studies in rodents [Sinclair and Crawford 1972; Benolken et al., 1973; Galli and Socini, 1983; Weisinger et al., 1999; Catalan et al., 2002], chickens [Budowski et al., 19...

in this paper, we generalize fuzzy banach contraction theorem establishedby v. gregori and a. sapena [fuzzy sets and systems 125 (2002) 245-252]using notion of altering distance which was initiated by khan et al. [bull. austral.math. soc., 30(1984), 1-9] in metric spaces.

Large-scale simulation models are essential tools for scientific research and environmental decision-making because they can be used to synthesize knowledge, predict consequences of potential scenarios, and develop optimal solutions (Clark et al. 2001, Berk et al. 2002, Katz 2002). Modeling is often the only means of addressing complex environmental problems that occur at large scales (Klepper ...

The bacteriae previously known as ‘Burkholderia cepacia’ have been reclassified as nine closely related species, sometimes referred to as ‘genomovars’ (Table 1), (Coenye et al, 2001; Mahenthiralingam et al, 2002). Collectively these are commonly referred to as ‘Burkholderia cepacia complex’ (Bcc). The various genomovars have different pathogenic potential (Keig et al, 1999; Bevivino et al, 2002...

Aflatoxins are compounds with a hepatotoxic, carcinogenic, and teratogenic potential that can affect either humans or animals (MOSS, 2002; SALEEMULLAH et al., 2006; D’MELLO; MACDONALD, 2002). According to an IARC estimates (INTERNATIONAL..., 2002), aflatoxins can be considered carcinogenic to humans (group I). The conditions that promote mycotoxin production are usually more restricted than tho...

fungi also (WiUiams et al. 1990, Xu and Leslie 1996. Kerrigan et al. 1993). Single strand confbrrnation polymorphism (SSCP) is usefuL for the detcction ofpoint mutations in genomic regions and has been applied for mapping known sequence data ofstructurai genes (Hunter et al. 1993, Orita et at. 1989). Two genetic maps have been rcported in L. edodes using RAPD markers (Kwan and Xu 20e2) and AFLP...
