Combinatorial Interaction Testing for Automated Constraint Repair
In this study presented at IWCT2017, Angelo Gargantini discusses a novel automated approach for finding and fixing conformance faults in software systems using combinatorial models. The goal is to discover and repair faults in the constraints of the model, assuming faults lie in the model and not the system itself.

Practical-7 Mayer s Hematoxylin & Eosin by: Khadija Rashed
It is a general purpose stain or micro-anatomical stain. Mayer's hematoxylin is used because it eliminates the necessity for differentiation and bluing of the section. It can be considered a progressive stain which produces a stained section with clearly defined nuclei while the background is completely colorless. Stain Solutions: Mayer's Hematoxylin Eosin Solutions
