abstract introduction: implicit cognitions, especially attentional bias for drug-related stimuli (da), have been shown to play an important role in sustaining of, progression of, and relapsing to substance abuse behaviors. the present research tested the feasibility of attentional retraining with drug attention control training program (dactp). method: participants were a sample of in-treatment...

We hypothesized that the integration of trees into agricultural land-use systems can reduce NO., leaching and increase subsoil N utilization. A field study was conducted on a Kandiudalfic Eutrudox (Ochinga site) and a Kandic Paleustalf (Muange site) in the subhumid highlands of Kenya to measure changes in soil NO, and water to 200-cm depth for one rainy season in four land-use systems (LUS): (i...

With increased cropping intensity, one would expect that more crop residue and C would be added to the Soil C sequestration can improve soil quality and reduce agriculsoil than with a crop-fallow system (Campbell et al., ture’s contribution to CO2 emissions. The long-term (12 yr) effects of tillage system and N fertilization on crop residue production and 1995, 2000b; Janzen et al., 1998a; Pete...

The general intent of these studies is to assess whether or not a slope is considered to be stable and, if not, to provide a “safe” set-back distance from the slope crest behind which structures and other facilities can be constructed. Unstable slopes and the land located between the unstable slope and the set-back line are called “Hazard Lands.” In a broad sense, Hazard Lands are those at risk...

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.

Terminated small grain cover crops are valuable in light textured soils to reduce wind and rain erosion and for protection of young cotton seedlings. A three-year study was conducted to determine the impact of terminated small grain winter cover crops, which are hosts for Meloidogyne incognita, on cotton yield, root galling and nematode midseason population density. The small plot test consiste...
