The present investigation was aimed to synthesis of silver nanoparticles (AgNPs) using Dodonaea viscosa (D.viscosa) leaf extract by an eco-friendly method. The leaf extract worked as bioreductant and stabilizer. The biosynthesized AgNPs was characterized by Ultraviolet visible (UV-vis) spectrophotometer, the leaf extract worked as reductant and stabilizer. The surface plasmon resonance (SPR) pe...

Several pest insects of human and livestock habitations are known as vectors of Salmonella enterica; however, the role of plant-feeding insects as vectors of S. enterica to agricultural crops remains unexamined. Using a hemipteran insect pest-lettuce system, we investigated the potential for transmission and retention of S. enterica. Specifically, Macrosteles quadrilineatus and Myzus persicae i...

Ewel, J., Gliessman, S., Amador, M., Benedict, F., Berish, C., BermfJdez, R., Brown, B., Martfnez, A., Miranda, R. and Price, N., 1982. Leaf area, light transmission, roots and leaf damage in nine tropical plant communities. Agro-Ecosystems, 7: 305--326. The vertical distribution of leaf area by species; transmission of photosynthetically active radiation; root biomass and fine-root surface are...

Dose calculations for intensity modulated radiation therapy (IMRT) require an accurate description of the radiation field defined by the multileaf collimator. A previously developed Monte Carlo phase space model has been modified to provide accurate dose verification for IMRT treatments on a Novalis linear accelerator. We have incorporated into the model the effects of the multileaf collimator ...

A light ray, incident at about 50 to the normal, io geometrically plotted through the drawing of the cross section of a soybean leaf using Fresnel's Equations and Snell's Law. The optical mediums of the leaf considered for ray tracing are: air, cell sap, chloroplast and cell wall. The above ray is also drawn through the same leaf cross section considering cell wall and air as the only optical m...
