In this work, a mixed integer programming model for the optimal design and production scheduling of an integrated ethanol/yeast supply chain is proposed. The model simultaneously determines the structure of a three-echelon supply chain (raw material sites-production facilities-customer zones), material flows among network nodes, the design of each installed plant, and the corresponding producti...

Plant systems for the production of recombinant immunogens have the potential to overcome obstacles currently impeding the delivery of vaccines to poorer, more remote populations by localizing production and reducing associated costs. The nature of the future plant-derived vaccine candidates will have an important impact on the extent to which universal access to vaccines can be achieved using ...

this experiment was conducted to quantify leaf production and senescence in wheat. the experiment was carried out at research farm of the gorgan university of agricultural sciences and natural resources, gorgan, iran in 2005 using a randomized complete design considering sowing dates as environment. treatments were sowing date (14 december, 20 jan and 21 feb, 2005) and cultivars (aria, atrak, k...

abstract persian shallot (moseer) belongs to alliaceae family, is a perennial medicinal and industrial edible alliums in iran. very little information is available about different aspects of this species particularly on its agronomical production. in order to determine optimum sowing date and plant density in persian shallot, an experiment was conducted as split plot based on complete randomize...

Technology used in controlled environment facilities ranges from simple plastic row covers to sophisticated controlled and automated greenhouse and growth chambers. Crop models that estimate plant responses to climactic, nutritional, and other factors have been used to support controlled environment plant production at many of these technology levels. Such models typically consist of mathematic...

tuberose (polianthes tuberosa l.) is one of the most important cut flowers in tropical and subtropical areas. this flower has forth order in cut flower and second order in bulbous plants production in iran. plant spacing and nitrogen necessity are the most important factors for tuberose quality and quantity. in this study, field experiment carried out as factorial design in randomized complete ...
