Properties of the spokes in coaxial and parallel - Plate plasma accelerator
Photographic, magnetic, and spectroscopic study of vortex spokes in coaxial and parallel-plate plasma accelerator
The 1980 US/Canada wheat and barley exploratory experiment. Volume 2: Addenda
Three study areas supporting the U.S./Canada Wheat and Barley Exploratory Experiment are discussed including an evaluation of the experiment shakedown test analyst labeling results, an evaluation of the crop proportion estimate procedure 1A component, and the evaluation of spring wheat and barley crop calendar models for the 1979 crop year
Crossover from diffusive to strongly localized regime in two-dimensional systems
We have studied the conductance distribution function of two-dimensional
disordered noninteracting systems in the crossover regime between the diffusive
and the localized phases. The distribution is entirely determined by the mean
conductance, g, in agreement with the strong version of the single-parameter
scaling hypothesis. The distribution seems to change drastically at a critical
value very close to one. For conductances larger than this critical value, the
distribution is roughly Gaussian while for smaller values it resembles a
log-normal distribution. The two distributions match at the critical point with
an often appreciable change in behavior. This matching implies a jump in the
first derivative of the distribution which does not seem to disappear as system
size increases. We have also studied 1/g corrections to the skewness to
quantify the deviation of the distribution from a Gaussian function in the
diffusive regime.Comment: 4 pages, 4 figure

Socio-economic impact of cluster marketing: The case of Ned Landcare Association sweet pepper cluster
Through clustering, opportunities exist for smallholder farmers to organize their output and to sell directly to institutional markets. This paper analyses the experiences of the cluster marketing approach in Barangay Ned, Lake Sebu, South Cotabato. The case demonstrates how farmers in the cluster group developed an enterprise plan, established linkages with a microfinance institution and negotiated sales to downstream market intermediaries. Farmers in the cluster increased their technical and marketing knowledge, improved their farming and marketing practices, improved their access to capital and increased their income. Trust, confidence, commitment and unity among cluster members were established through the cluster marketing approach
