E. Afra R. Dashtbani,

One of the main issues of nanotechnology is producing materials with new properties. Nanotechnology, as a powerful tool, has the ability to create evolution in the agricultural system and food–medicinal industries across the world. Producing a high-performance material from reclaimed cellulose material will increase motivation to recycle these materials at all phases of paper production and rem...

During 1998-99, a field experiment was conducted to investigate the effects of residual Processed Municipal Waste Leachate (PMWL) on growth and yield of wheat (variety Roshan). The treatments consisted of residual amounts of 0, 150, 300 and 600 t/ha of PMWL and a residual N, P, K, and Zn fertilizer treatment in a randomized block design with 3 replications. In 1998, rice seedlings were transfer...

Knowledge of virus and replication kinetic is one of the most important issues in the vaccine production. The present study aimed to evaluate the best harvesting time of H9N2 avian influenza virus (AIV) vaccine strain inoculated in specific pathogen free (SPF) embryonated chicken eggs (ECE)s. For this purpose, 10-5 dilution of AIV (A/Chicken/Iran/99/H9N2) was inoculated into 336, 11-day old ECE...
