There are two chain structures consisting of main actors and supporting actors. The structure the first is Farmers → Small Collectors, Large Collectors Exporters. At same time, second is: Farmers, Home Industry, Collecting agents. Areca farmers get an added value IDR 1,647.12/kilogram with ratio 71.80%. collectors 994.46/kilogram 22.10%. Prominent 702.67/kg a value-added 13.01%. home industry o...

In this paper, artificial neural networks (ANNs) and genetic algorithms (GAs) are used for the design of solar flat-plate collectors. It is proved in this paper that by using the Taguchi method for selecting the data required for training the ANN is very effective in allowing the network to learn the behavior of the system satisfactorily. The parameters on which the flat-plate collector design ...

Fish predation interferes with mussel seed population dynamic and is an important limiting factor on seed supply in several areas of mussel farming production. In the present study we assessed the impact of fish predation in a mussel farm sited in the Rıa de Ares-Betanzos (Galicia, NW Spain). To assess fish impact on recruitment, we have quantified mussel recruitment densities with or without e...

The lymphatics lying along the internal thoracic artery and vein, which are termed the "internal mammary lymphatics" (IML), were minutely dissected in 134 adult cadavers (80 males and 54 females, aged 27-94 years) in order to clarify the configuration of IML in the superior mediastinum. On the right side, IML frequently terminated at the brachiocephalic angle (BA) nodes and often at the nodes s...

In this Application Note we show three system configurations for recovery collection with the Agilent 1100 Series purification system. One configuration uses a 12-position/13-port valve 3 in the waste line of the fraction collector, which offers up to twelve recovery locations. Another possibility is to use a third-party fraction collector, controlled by the ChemStation through external contact...

This paper studies the reliability and validity of naturalistic speech errors as a tool for language production research. Possible biases when collecting naturalistic speech errors are identified and specific predictions derived. These patterns are then contrasted with published reports from Germanic languages (English, German and Dutch) and one Romance language (Spanish). Unlike findings in th...

Nonrandom collecting practices may bias conclusions drawn from analyses of herbarium records. Recent efforts to fully digitize and mobilize regional floras online offer a timely opportunity to assess commonalities and differences in herbarium sampling biases. We determined spatial, temporal, trait, phylogenetic, and collector biases in c. 5 million herbarium records, representing three of the m...

outdoor experiments on a once-through single glazed solar air heater with perforated metal absorber plate were conducted to determine the practical effect of absorber plate porosity as well as suction air flow rate on the collector thermal efficiency and its total pressure drop. three aluminum absorber plates were made perforated by drilling circular holes with different diameter/pitch ratios i...

We report the first realization of a charge injection transistor with a complementary collector. The device is implemented using InGaAs/InAlAs/InGaAs heterostructure material grown by molecular beam epitaxy. Real space transfer of hot electrons into the p-type collector leads to a luminescence signal arising from the recombination of the injected electrons with holes in the collector active reg...
