The community of science has a lot of research problems. The researchers are eager to find proper solutions. The solutions are based on investigation and verification. Anyway, the papers should be published to be available for all interests and specialists to keep the scientific wheel running-on. The recognized journals have citations and impact factor (IF) to be qualified in comparison with others. IF is accounted by dividing the citations number per year on the total number of papers for the last two years. IF journals are available within Thomson Reuters Scientific indexation only that is updated every year.
