The influence of various cropping sequences on population densities of Meloidogyne hapla and carrot yield was studied in organic soil under microplot-and field conditions. Spinach, radish, barley, oat, and wheat were poor or nonhosts for M. hapla. Population densities of M. hapla were maintained or increased on cabbage, celery, lettuce, leek, marigold, and potato. Marketable percent-age and roo...

We show that the onion-to-vortex switching field in dense arrays of nanostructured ferromagnetic rings is strongly dependent on the angle between the applied magnetic field and the array’s main axis. The variations in switching field of up to 8 mT are connected to the anisotropy produced by dipolar interactions between domain walls in the rings. The interactions stabilize the onion state in ali...

The effects of aqueous extracts of onion and garlic as well as of garlic oil were studied on the process of blood coagulation and fibrinolysis in vitro. Only onion was found to exhibit anti-coagulant and fibrinolytic activity while garlic extract as well as garlic oil were inactive.

Onion routing is a scheme for anonymous communication that is designed for practical use. It has not been modeled formally, however, and therefore its anonymity guarantees have not been rigorously analyzed. We give an IO-automata model of an onion-routing protocol and, under possibilistic definitions, characterize the situations in which anonymity and unlinkability are guaranteed.

Seedling, seedling parts and callus cultures of onion were tested for their antidiabetic activity by feeding the tissue-extracts to diabetic rats. The results indicated much higher antidiabetic activity in callus cultures as compared to natural bulbs of onion. These results may be of pharmaceutical significance since the callus can be used as an alternative source for the isolation of antidiabe...

Scientific name: Xanthomonas axonopodis pv. allii (Roumagnac et al., 2004a,b). Synonyms: Xanthomonas campestris pv. allii (Kadota et al., 2000). Taxonomic position: Proteobacteria: Gammapropteobacteria: Xanthomonadales: Xanthomonasdaceae. Common names: Xanthomonas axonopodis pv. allii is the causal agent of onion bacterial blight (syn. Xanthomonas leaf blight of onion). EPPO code: XANTAA. Phyto...

Many workers assume that tessera terrain—marked by multiple tectonic lineaments and exposed in crustal plateaus—comprises a global “onion skin” on Venus. A growing body of structural, mechanical, magmatic, gravitational-topographic, and geologic evidence indicates that tesserae record the local interaction of individual deep-mantle plumes with an ancient, globally thin Venusian lithosphere, res...

Diesel exhaust particles (DEPs) are particulate matter from diesel exhaust that contain many toxic compounds, such as polyaromatic hydrocarbons (PAHs). Some toxicities of PAH are thought to be expressed via aryl hydrocarbon receptors (AhRs). The male reproductive toxicity of DEPs might depend on AhR activation induced by PAHs. We hypothesized that AhR antagonists protect against the male reprod...
