Foldscope (Paper Microscope): Inexpensive research tool for farmers to identify plant pathogens

Foldscope: Origami-Based Paper Microscope

Here we describe an ultra-low-cost origami-based approach for large-scale manufacturing of microscopes, specifically demonstrating brightfield, darkfield, and fluorescence microscopes. Merging principles of optical design with origami enables high-volume fabrication of microscopes from 2D media. Flexure mechanisms created via folding enable a flat compact design. Structural loops in folded pape...

a review approaches to identify enteric bacterial pathogens

conclusions therefore, development of rapid diagnostic methods with suitable sensitivity and specificity is very important about this infectious disease. in this review, we will discuss some of the important diagnostic methods. context diarrhea is a common disease across the world. according to who, every year about two billion cases of diarrhea are reported in the world. it occurs mainly in th...

Interdiction problem as a tool to identify an effective budget allocation to quality improvement plans

In the face of budgetary limitations in organizations, identifying critical facilities for investing in quality improvement plans could be a sensible approach. In this paper, hierarchical facilities with specified covering radius are considered. If disruption happens to a facility, its covering radius will be decreased. For this problem, a bi-objective mathematical formulation is proposed. Crit...
