Confocal imaging technology utilizes fluorescence optics, where laser light is focused onto a specific spot at a defined depth in the sample. A considerable number of images are produced regularly during the process of research. These images require methods of unbiased quantification to have meaningful analyses. Increasing efforts to tie reimbursement to outcomes will likely increase the need for objective data in analyzing confocal microscope images in the coming years. Utilizing visual quantification methods to quantify confocal images with naked human eyes is an essential but often underreported outcome measure due to the time required for manual counting and e

The margin of dumping was calculated by taking the difference between the normal value and the export price. If it exceeds 2%, then there is dumping. Product dumping in Iraq has increased since 2003, and it is increasing from year to year for many types of agricultural and food commodities. Main reasons are the high rate of imports and the absence of trade policies represented by customs tariffs which in turn control the trade exchange. The research concluded that there is an intentional dumping in the trade of some agricultural commodities with Iraq from neighboring countries. Trade exchange with these countries h
