Large leaves in warm, moist environments confer an advantage in seedling light interception efficiency

An Efficient Data Replication Strategy in Large-Scale Data Grid Environments Based on Availability and Popularity

The data grid technology, which uses the scale of the Internet to solve storage limitation for the huge amount of data, has become one of the hot research topics. Recently, data replication strategies have been widely employed in distributed environment to copy frequently accessed data in suitable sites. The primary purposes are shortening distance of file transmission and achieving files from ...

An efficiency measurement model in fuzzy environments, using data envelopment analysis

Data Envelopment Analysis (DEA) is a technique used to compare efficiency in various sectors such as hospitals, chain stores, and dealerships. It represents a set of linear programming techniques and uses deter-ministic data (inputs and outputs), in stable conditions. The DEA technique cannot be used when there is data with indeterministic nature, or when there is an environment with dynamic co...

Light interception and radiation use efficiency response to narrow-wide row planting patterns in maize

The light deficiency in the canopy is not the main factor limiting maize (Zea mays L.) production but the lower radiation use efficiency (RUE). Conservation tillage planting patterns were used to construct a sustainable agricultural system for soil protection and higher RUE. On these bases, we tried to create more uniform light distribution in crop canopy for increasing radiation use efficiency...

Large Meningioma in an Infant

Abstract Background Histologically confirmed meningiomas in first year of life are quite rare. However, review of the sporadic cases in the literature reported meningioma in infants. Those have unique features in common. Case presentation An 11 month-old Iranian male infant presented with a several weeks history of decrease in movement of his right sided upper and lower extremities. Brai...
