honey is the natural sweet substance produced by honey bees from nectar of plants or from secrerations of living parts of plants or excretions of plants sucking insects on the living pans of plants. physico-chemical properties of honeys in each region are related to kind of plant and flower.therefore ,knowing of component is very important. in this study thirty samples of honey were collected f...

The aim of this work is to model a jet diffusion flame, to show the corresponding proof of existence of solutions, and to present numerical results. The model is based on the flamelet equations for the chemistry and on the mixture fraction for the flow. Numerical tests are carried out for Sandia Flame D and the results are found to compare well with available data found in the literature.

We prove a general finite-dimensional reduction theorem for critical equations of scalar curvature type. Solutions of these equations are constructed as a sum of peaks. The use of this theorem reduces the proof of existence of multi-peak solutions to some test-functions estimates and to the analysis of the interactions of peaks.
