The fundamental role of ice particle collisions in the separation of electric charge and generation of lightning in thunderclouds is now reasonably well established (Latham, 1981; Williams, 1985; Saunders, 1995). Charge separation and lightning are also prevalent in volcanic eruptions. A recent literature survey by McNutt and Davis (2000), and its recent extension, has shown more than 150 incid...

The purpose of this study is to determine the magnitude of the fisheries sector along the Amazon river in Brazil. Total income and employment was estimated for the principal activities comprising the fisheries sector: fish processing plants, stores selling fishing gear, gas stations, restaurants, ice factories, and boatyards based on interviews conducted with businesses in 15 cities along the A...

RNA polymerase II (RNAPII) transcription has been proposed to occur at transcription factories; nuclear focal accumulations of the active, phosphorylated forms of RNAPII. The low ratio of transcription factories to active genes and transcription units suggests that genes must share factories. Our previous analyses using light microscopy have indicated that multiple genes could share the same fa...

Economic historians tend to explain the rise of the cooperative form in agriculture from the advantage of cooperative over private factories in reducing transaction costs with suppliers. This study provides a first test of this thesis using data on 1130 dairy factories in The Netherlands. Indeed, we find that cooperative factories performed significantly better than private factories. The persi...
