Disputed lands

In this paper we consider the classical problem of dividing a land among many agents so that everybody is satisfied with the parcel she receives. In the literature, it is usually assumed that all the agents are endowed with cardinally comparable, additive, and monotone utility functions. In many economic and political situations violations of these assumptions may arise. We show how a family of...

Egyptian propolis: 3. Antioxidant, antimicrobial activities and chemical composition of propolis from reclaimed lands.

The free radical scavenging effect of two propolis samples collected from reclaimed land, Egypt as well as of vitamin C and caffeic acid in 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical system was determined. The antimicrobial (Staphylococcus aureus; Escherichia coli and Candida albicans) activity was also investigated. The results of the free radical scavenging effect of El-Saff and Ismail...

Rab3 GTPase Lands Bruchpilot

Active zones are the sites of neurotransmitter release, but their assembly mechanisms are poorly understood. In this issue of Neuron, Graf et al. perform a genetic screen in Drosophila and uncover a novel role for the Rab3 GTPase in organizing the active zone at the neuromuscular junction.

loaded and a portion of the nitrate is absorbed by the blood stream as nitrate and nitrite. Some of the nitrate Nitrate contained in forage may pose performance and health risks that is absorbed recycles back to the rumen through to ruminants. With timely and accurate assessment of forage nitrate levels, steps to reduce the risks of excessive nitrate intake by livestock saliva thereby adding ag...
