The objective of this study was to evaluate the strategies for groundwater resources management, including competition groundwater pumping, optimal control in groundwater pumping, groundwater use and tax policy, water users' participation in groundwater pumping control, and cooperation among government and water user associations in Narimany plain located in Khorasan Province. Irrigation wate...
Transgenic maize engineered to express insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) has become widely adopted in U.S. agriculture. In 2009, Bt maize was planted on more than 22.2 million hectares, constituting 63% of the U.S. crop. Using statistical analysis of per capita growth rate estimates, we found that areawide suppression of the primary pest Ostrinia nubilalis (Eu...
The reform of the European Union's sugar regime caused potential decreasing beet prices. Therefore, the Speeding Up Sugar Yield (SUSY) project was initiated. At the start, a 3 × 15 target was formulated: in 2015 the national average sugar yield in the Netherlands equals 15 t/ha (60% of the sugar beet potential) and the total variable costs 15 euro/t sugar beet, aspiring a saving on total variab...
In this article we propose and solve a game-theoretic model of a rank-order tournament with private information. Using the contract settlement data from a poultry company, we estimate a fully structural model of a symmetric Nash equilibrium of this game. We show that growers’ equilibrium effort depends on four factors: the spread in piece rates between the performance brackets, the number of pl...
Information flows are weaker in a heterogeneous population when the performance of a new technology is sensitive to unobserved individual characteristics, preventing individuals from learning from neighbors’ experiences. This characterization of social learning is tested with wheat and rice data from the Indian Green Revolution. The rice-growing regions display greater heterogeneity in growing ...
Several viruses can cause devastating diseases in domestic apple (Malus x domestica Brokh.). Major viruses affecting apple production in New York are apple chlorotic leaf spot virus (ACLSV), apple stem pitting virus (ASPV), apple stem grooving virus (ASGV). These viruses are common and generally latent; in other words, they do not cause acute symptoms on most commercial cultivars. However, when...
The behaviour of some immunologic parameters was studied in order to explain the presence or the lack of symptomatology in subjects with IgE specific to foods. In particular, we compared the levels of serum and salivary IgA and IgE antibody specific to apple in 33 patients allergic to birch and with anti-apple IgE, of whom 24 had oral allergy syndrome after eating apple and nine were apple tole...
Innovative techniques were developed in the Isafruit project in order to create a more ecological sustainable way of fruit growing. Before fruit growers will consider implementation of these innovations they need information concerning their economic sustainability. The economic model ProfitFruit is made to evaluate the profitability of innovative techniques. ProfitFruit includes a database wit...
The effects of apple pomace diets on rumen microbial population, movement of ingesta from the rumen, and water intake were studied in two trials with beef steers. Trial 1 was a 5 • 5 Latin square in which five ruminal fistulated steers were fed either corn silage plus cottonseed meal (CSM), apple pomace plus CSM, apple pomace plus urea, apple pomace plus urea and starch, or apple pomace plus ur...
Both the origin of domesticated apple and the overall phylogeny of the genus Malus are still not completely resolved. Having this as a target, we built a 134,553-position-long alignment including two previously published chloroplast DNAs (cpDNAs) and 45 de novo sequenced, fully colinear chloroplast genomes from cultivated apple varieties and wild apple species. The data produced are free from c...
