In this paper an intelligent separation system, based on artificial neural networks (ANNs), for classifying four different varieties of Iranian pistachio nuts, namely, Kaleghouchi (Ka), Akbari (Ak), Badami (Ba) and Ahmadagaee (Ah) is presented. To develop the ANN models a total of 3200 pistachio sound signals, 800 samples for each variety, were recorded. Features of pistachio nut varieties were...

T he U.S. pistachio industry, which is located almost exclusively in Califor-nia, has experienced phenomenal growth over the past thirty years. The value of U.S. production of pistachios grew from nearly zero in 1976 to $333 million by 2002. The U.S. share of the rapidly growing global pistachio industry has also increased. Outside California, the main pistachio growing region is the Middle Eas...

While there is an increasing realization of the potential that IT offers for human welfare, IT-induced productivity and growth are confined to the developed world. It is argued that even though the international digital divide is a reality, there are certain specific characteristics of the new technology that leave scope for mitigating, if not totally bridging, the gap when appropriate policies...

Commodities (rural and non-rural) account for a significant proportion of Australia’s exports. Even though tourism and manufactured exports have grown strongly in recent years, earnings from commodities were around two thirds of total export earnings from goods and services in 1991/92. This was despite the cyclically low level of prices. Furthermore, the volatility of commodity prices is an imp...

s for Paper Presentations Margins of Labor Market Adjustment to Trade Rafael Dix-Carneiro (with Brian K. Kovak) We use both longitudinal administrative data and cross-sectional household survey data to study the margins of labor market adjustment following Brazil's early 1990s trade liberalization. We document how workers and regional labor markets adjust to trade-induced changes in local labor...

Iran stands first both in production and export of Pistachio in the world and earns sizable income from its export. Despite such a position in global market, Farmers and traders in the country are suffering from a wide kind of bottlenecks. This study aimed to define the critical constraints and to suggest the best way to reduce them. Necessary data were collected through personal interview of r...

AIMS The aim of this study was to apply polymer films containing silver nanoparticles as a new method for increasing the shelf life and preserving the quality of export/commercial products of Kerman Province and determine the ideal temperature for preserving these products. METHODS After preparing nano-composite films containing silver nanoparticles (3% and 5% by weight), Mazafati dates were ...

Pistachio is a nut with high consumption that can be affected by aflatoxin contamination. Regarding influence of this fungus on global trade, broad studies in this area seem to be necessary. In this research, pistachio nuts were coated with methyl cellulose at different concentrations of 0.1%, 0.5%, 1%, and 2% by immersion method. Samples were stored in an incubator (25°C) for 4 months. Imaging...

cold stress is one of the important factors which will reduce crop yield and fruit production in world. Early spring cooling and freezing weather is mostly. Possible this may considerable damage pistachio productions and farmer will lose most of their profit. Therefore study which show how pistachio plant cope freezing weather is valuable and important. The special role of amino acid in plant r...
