A novel printed octagonal fractal microstrip antenna with semi-elliptical ground plane is presented for ultra wide band applications. The proposed antenna has a compact size of 20×20×1 mm³. The measured result of the antenna exhibits the ultra wide band characteristics from 2/9 to 14/2 GHz. In this paper, reducing antenna’s size by 35%, the same results were achieved, while small dimension frac...

Drought stress causes severe metabolic dysfunctions by formation of oxidative stress that may lead to damage in DNA, inactivation of enzymes, and lipid peroxidation. Plants have developed different morphological, physiological, and biochemical mechanisms to withstand the drought stress. Plant growth regulators (PGRs) are...

Evening primrose (Oenothera biennis L.) is native to North America, belongs to Onagraceae family, and is a biennial plant. This experiment was performed as factorial based on a completely randomized design in three replications. The main purpose of the study was to evaluate the effect of moist-chilling and GA</s...

Arsenic (As) is a toxic metalloid which is usually found in rice fields as a contamination and has negative effects on the plant growth and reduces the crop yield. Similar to heavy metals, the deleterious effects of As may be due to, at least in part, the amount of absorbed As and disturbance of the plant water status. I...

Cadmium is a main toxic pollutant and poses a considerable threat to human health. In other to study the effect of Cd stress on traits of garden cress and radish, an experiment was conducted based on a completely randomized design in an aeroponic system. In this study CdCl2</sp...
