In Washington, over fifty percent of the wheat produced under rainfed conditions receives less than 300 mm of annual precipitation. Hence, a winter wheat-summer fallow cropping system has been adopted to obtain adequate moisture for winter wheat production. Current tilled fallow systems are exposed to significant soil degradation from wind and water erosion. As a result, late-planted no-till fa...

In a survey conducted in 1984 in Essex, Lambton, and Middlesex Counties of Ontario, Canada, greater incidences of head blight and greater concentrations of deoxynivalenol in grain were observed in fields of winter wheat planted after corn than in those planted after soybeans, barley, and mixed grains. Neither head blight nor deoxynivalenol level were correlated significantly with soil P, K, or ...

Mass balance performance data from side by side studies of planted and unplanted gravel-bed treatment wetlands with horizontal subsurface-flow are compared. Planted systems showed enhanced nitrogen and initial phosphorus removal, but only small improvements in disinfection, BOD, COD and suspended solids removal. Direct nutrient uptake by plants was insufficient to account for more than a fracti...

The purpose of this experiment was to investigate whether low-intensity pulsed ultrasound (LIPUS) irradiation can inhibit dentoalveolar ankylosis in transplanted rat teeth. LIPUS irradiation (the pulsed ultrasound signal had a frequency of 3.0 MHz, a spatial average intensity of 30 mW/cm2, and a pulse ratio of 1:4) was performed on the face over the re-planted teeth of rats for 4 weeks. After t...

A poplar planted system resulted in the complete removal of at least 19 of the 29 potential polychlorinated biphenyl (PCB) congeners detected in trace amounts (37.9 ng g-1 in total) in a commercial garden soil, while the unplanted soil only had 2 congeners completely removed after 96 days. In addition, the most recalcitrant congener, PCB 52, only decreased by 0.1% in the unplanted reactors whil...

The problem of community detection from noisy observations of interactions between individuals has important applications to diverse areas such as biology, sociology, and computer science. This problem is particularly interesting when the number of interactions is on the order of the size of the populations, that is the graph where two interacting individuals are connected by an edge is sparse....

Tree shelters were used in an ecological restoration effort in 1999 and 2000 to test the decrease in transplant shock and increase in growth and survival of two selected Mediterranean species, carob tree (Ceratonia siliqua L.) and cork oak (Quercus suber L.), planted in a dry degraded region. At plantation, two treatments were established, one planted with 60 cm tall TUBEX MinitubesTM and the o...

Results of an 11 yr study of the growth and survival of planted northern red oak (Quercus rubra L.) seedlings (2-0 bare-root) are presented. More than 4,000 seedlings were planted under shelterwood overstories that were harvested 3 yr after planting. Results are expressed as planted-tree dominance probabilities. Dominance probability is the probability that a planted tree will live to attain a ...

We consider the problem of recovering an unknown $k$-factor, hidden in a weighted random graph. For $k=1$ this is planted matching problem, while $k=2$ case closely related to travelling salesman problem. The inference solved by exploiting information arising from use two different distributions for weights on edges inside and outside sub-graph. argue that, large size limit, phase transition ca...

exiting diversity is the basis of selection in plant breeding programs. diversity in morphological traits is studied by different methods of multivariate analysis. this study was conducted to estimate the genetical diversity of new corn hybrids based on the morphological traits. in this study, 40 new grain and forage corn hybrids with five commercial varieties as control treatments were planted...
