  Organic fertilization has been practiced in Iran due to the shortage of soil organic matter. In recent years, attention has been payed to the organic fertilizers because their commercial production has recently started and demands for their application have increased. The objectives of this study were to investigate the effects of organic fertilizer type, rates and times of application on the...

t—Fault injection is a widely accepted for the evaluation of device and system ty, by mean of dynamic analysis of a digital mplemented in a FPGA. A set of test vectors ed and output vectors are monitored while a of faults are injected deliberately. The fault n strategy in our platform consists of a ed modification of the FPGA’s configuration affecting the targeted netlist nodes. The data sequen...

A search of the current scientific literature yields a limited number of studies that describe the use of Fourier transform infrared (FT-IR) spectroscopic imaging for the analysis of forensic casework, which is likely due to the fact that these instruments are fairly new commodities to the field of analytical chemistry and are therefore not yet commonplace in forensic laboratories. This report ...
