iran is one of the most important rainbow trout (oncorhynchus mykiss) producing countries in the world and fingering production is the key factor for this industry. the present experiment was conducted to determine the role of the coelomic fluid in artificial fertilization and to study the interactive effect of different brood fish coelomic fluid on fertilization process during 60 min storage a...

seed deterioration is loss of seed quality, viability and vigor due to effect of adverse environmental factors. many of our crops are reproduced through seeds, and throughout the world large quantities are produced, stored and transported. seed ageing during storage may cause retardation of field establishment, and may eventually result in seedling abnormalities or even failure of emergence. du...

Due to its advantages over traditional data centers, there has been a rapid growth in the usage of cloud infrastructures. These include public clouds (e.g., Amazon EC2), or private clouds, such as clouds deployed using Open-stack. A common factor in many of the well-known infrastructures, for example Openstack and Cloudstack, is that networked storage is used for storage of persistent data. How...

Magnetic data storage is pervasive in the preservation of digital information and the rapid pace of computer development requires ever more capacity. Increasing the storage density for magnetic hard disk drives requires a reduced bit size, previously thought to be limited by the thermal stability of the constituent magnetic grains. The limiting storage density in magnetic recording is investiga...
