Information on dissipation kinetics of pesticides in food crops and other plants is a key aspect in current risk and impact assessment practice. This is because human exposure to pesticides is predominantly caused by residues in agricultural crops grown for human and animal consumption. However, modeling dissipation of pesticides in plants is highly uncertain and therefore strongly relies on ex...
In the Caribbean, insecticide resistance is widely developed in Aedes aegypti and represents a serious obstacle for dengue vector control. The efficacy of pyrethroid and organophosphate ultra-low volume space sprays was investigated in Martinique where Ae. aegypti has been shown to be resistant to conventional insecticides. In the laboratory, a wild-field caught population showed high levels of...
Introduction: Radiation therapy planning (RTP) is one of the clinical applications in which both CT scan and MRI are used. MR and CT images are applied to determine the target volume and calculation of dose distribution, respectively. In addition, using two imaging modalities increases the department workload and cost. In this study, an algorithm was presented to create synthet...
one of the applications of nanotechnology is use of carbon nanotubes for the targeted delivery of drug molecules. to demonstrate the physical and chemical properties of biomolecules and identify new material of drug properties, the interaction of carbon nanotubes (cnts) with biomolecules is a subject of many investigations. cnts is a synthetic compound with extraordinary mechanical, thermal, el...
The American leafhopper Erasmoneura vulnerata, detected in Europe the early 2000s, has recently become a pest North-Italian vineyards. Infestations were recorded organic and conventional vineyards despite application of insecticides targeting other pests. vulnerata completes three generations per year, second generation is frequently associated with large populations. selection appropriate acti...
the present study aimed to evaluate the antimicrobial activity of a hetroalkyl oximec synthetic compoundderivative (benzophenone o-4-bromoethyl oxime) against two gram positive and three gram negative bacteria.the antibacterial characteristic of this compound was shown using the circular zone diameter of bacterial growthinhibition by disk-diffusion method. in addition, the random amplified poly...
