There are many kinds of systems that can be analyzed both quantitatively and qualitatively. It tries to overcome its quantitative disadvantage by staying qualitatively superior. Multimodal perception is qualitatively different from unimodal perception. Below the critical temperature, the van der Waals equation seems to predict qualitatively incorrect relationships. Note that one-dimensional and multidimensional cases are qualitatively different. In many physical and biological systems, qualitatively different influences can oppose each other. Nonlinear effects fall into two qualitatively different categories, parametric and non-parametric effects. These results picture an evolution that is qualitatively similar to that, described above. They can give qualitatively different results even for very small systems. Vygotsky described inner speech as being qualitatively different from verbal external speech. Such questions are more likely to be studied qualitatively. In other words, DNA immunization induces a qualitatively superior response. Such data, while relevant to residents are of a qualitatively different type. Turbulent flow causes dephasing and signal loss allowing valvular disease to be qualitatively appreciated. The regulation of state power presented a "qualitatively different" undertaking.
