Tomographic imaging devices, such as PET/SPECT, suffer from their low resolution capabilities and produce images having partial volume error and non- uniform reconstructed resolution across their field of view. This results in quantification errors and hinders the optimum use of these images in diagnostic and therapeutic applications. This writing provides a detailed insight into the tomographic imaging, image reconstruction methods and proposes recovery methods for non-uniform resolution and partial volume errors in Tomographic image reconstruction. Specifically, it details the ...

Spodoptera litura causes enormous losses in many economically important crops. Three years monitoring of conventional and new chemistry insecticides revealed chlorpyrifos, quinalphos, deltamethrin, -cyfluthrin, emamectin and indoxacarb more toxic than other insecticides against most field populations. Cypermethrin and deltamethrin with fipronil showed synergistic effect both at 1:1 and 1:10 in field populations. However, these populations were highly antagonistic to organophosphates when mixed with synthetic pyrethroids. Using single pair crosses for genetics studies, deltamethrin and...

The ordinary acceptance sampling plans are used to accept or reject the submitted product on the basis of random sample taken from the lot. This sampling scheme is used to test the item one by one. In practice, there are testers accommodating multiple items are available. In this situation, group acceptance sampling is used more efficiently. The basic purpose of group acceptance sampling plans is that it can reduce the cost and the time of the experiment than the ordinary acceptance sampling plans.The group acceptance sampling provides the strict inspection of the product under...
