Return on Investment (ROI) is one of the most popular performance measurement and evaluation metrics used in business analysis. ROI analysis (when applied correctly) is a powerful tool for evaluating existing information systems and making informed decisions on software acquisitions and other projects. Decades ago, ROI was conceived as a financial term and defined as a concept based on a rigoro...

A small detector or limited gantry rotation angles may cause data truncation, in which case the entire object cannot be completely reconstructed. However, a small region of interest (ROI) may be recoverable in certain truncation situations. Two analytical methods have been proposed for exact ROI reconstruction. Here we evaluate the capability of ROI reconstruction using an maximum-likelihood ex...

the laboratory infection of lymnaea gedrosiana with 2,5 and 10 miracidia of fasciola gigantica resulted in infection rates of 20%, 40% and 69%, respectively, with a prepatent period of 66-88 days. there was a significant difference in infection rate between the snails infected with 2 and those with 10 miracidia (p<0.05). at 92 days post- infection there was 25% to 33.3% of live snails still har...

Medical images show a great interest since it is needed in various medical applications. In order to decrease the size of medical images which are needed to be transmitted in a faster way; Region of Interest (ROI) and hybrid lossless compression techniques are applied on medical images to be compressed without losing important data. In this paper, a proposed model will be presented and assessed...

Introduction: Human Cytomegalovirus (HCMV) or Human Herpes Virus Type-5(HHV-5) is a member of herpesviridae placed in subtype beta herpesvirinae. CMV is a ubiquitous pathogenic virus and can infect humans all through their life. Prevalence of CMV infection in developed countries is about 45% and in developing countries it varies up to 100%. CMV infection during pregnancy is very important, beca...

Seven hundred and sixty-eight blood samples of pregnant cattle from four Holstein dairy herds that are farmed in the vicinity of Tehran were used to evaluate the seroprevalence of Neospora caninum infection by enzyme-linked immunosorbent assay (ELISA). Two hundred and ninety-eight of the 768 blood samples (38.8%) were positive for this infection. The prevalence of infection in the herds varied ...
