An overview of recent experimental results on instability and dynamics of jets at low Reynolds numbers is given. Round and plane, macro and micro jets are under the consideration. Basic features of their evolution affected by initial conditions at the nuzzle outlet and environmental perturbations are demonstrated.

Activation of β-catenin was shown to be of central importance for hair development and cycling. Recent progress brought more understanding to how Wnt signaling is regulated during hair follicle generation and regeneration, telogen-anagen reentry, and extra-follicular macro-environmental modulation. This new understanding presents multiple possibilities to fine tune Wnt signaling for desired hai...

The article situates a lead poisoning epidemic in Uruguay within recent processes of neoliberal and environmental reform. It argues industrial contamination and its socio-political responses have become prevalent through neoliberal-inspired transformations in production and consumption, the dismantling of state services, and increased social vulnerability to affliction. Contrary to orthodox the...

The potential benefit of drought-tolerant (DT) corn (Zea mays L.) hybrids may depend on drought intensity, duration, crop growth stage (timing), and the array of drought tolerance mechanisms present in selected hybrids. We hypothesized that corn hybrids containing DT traits would produce more consistent yields compared to non-DT hybrids in the presence of drought stress. The objective of this s...

to study the effect of different fertilizing systems on macro and micro nutrients uptake by annual medic (medicago scutellata cv. robinson) an experiment was conducted under dry farming and irrigated conditions at two research stations (sararood dryland agricultural research institute and soil fertility research station in mahidasht) during 2009 growing season. the experimental treatments consi...
