Materials and Methods The Neely-Kinyon Long-term Agroecological Research (LTAR) site was established in 1998 to study the long-term effects of organic production in Iowa. Treatments at the LTAR site, replicated four times in a completely randomized design, include the following rotations: conventional corn-soybean (C-S), organic corn-soybean-oats/alfalfa (C-S-O/A), organic corn-soybean-oats/alf...

Glyphosate-resistant corn and soybean are grown in rotations in the Midwest, including Nebraska. Volunteer corn is a problematic weed in soybean fields because it causes harvest problems, reduces yield and seed quality, and potentially harbors insects, pests, and diseases. Several pre-packaged herbicides have been registered in soybean in recent years, but response of volunteer corn to these he...

There is documented evidence that infection in laboratory animals can often influence the outcome of experiments. All infections, apparent or inapparent, are likely to increase biological variability. As a research project concerning the diversity and distribution of parasites of rabbit and guinea pig in a conventional laboratory animal house, about 87 rabbits (from 700 ) and 105 guinea pigs (f...

Following a familiar route and finding a novel route in a familiar environment depend on different cognitive processes and representations. A recent study by Hartley et al. begins to identity the neural basis of route following and wayfinding in humans. Their study also raises important questions about the functions of the hippocampus.

Reading a book is also kind of better solution when you have no enough money or time to get your own adventure. This is one of the reasons we show the teaching medical students in primary and secondary care a resource book as your friend in spending the time. For more representative collections, this book not only offers it's strategically book resource. It can be a good friend, really good fri...

The diving beetle genus Neobidessodes Hendrich & Balke, 2009 contains 10 species. Nine of them were considered endemic to Australia, one the Trans Fly Savanna and Grasslands Ecoregion New Guinea island. Here, we provide first report Australian species, mjobergi (Zimmermann, 1922), from same region Guinea. We suggest that more focused research will reveal occurrence far species in

Onion (Allium Cepa) contains high levels of flavonoids. Although there are many studies indicating the inhibitory effects of flavonoids on xanthine oxidase, there is no report on the effect of onion on this enzyme. Therefore, in the present study, the inhibitory effects of onion on xanthine oxidase are investigated. Fresh filtered juice of onion was prepared and its inhibitory effect on guine...

Identifying and using native insect resistance genes is the core of integrated pest management. In this study, 10 experimental corn, Zea mays L., hybrids and 10 inbred lines were screened for resistance to major ear-feeding insects in the southeastern Coastal Plain region of the United States during 2004 and 2005. Ear-feeding insect damage was assessed at harvest by visual damage rating for the...
