Band broadening theory (Van Deemter equation) It is well recognized now that column band broadening originates from three main sources: 1. multiple path of an analyte through the column packing; 2. molecular diffusion; 3. effect of mass transfer between phases. In 1956 J.J. Van Deemter introduced the equation which combined all three sources and represented them as the dependence of the theoretical plate height (HETP) on the mobile phase linear velocity. Originally‚ it was introduced for gas

methods‚ theorems‚ and models for solving equations that can be defined by and/or solved using numerical methods‚ graphical methods‚ or analytical methods. These three methods can solve small equations such as y=mx+b to x=-b±b2-4ac2a. Analytical methods use mathematical theorems to fully predict the implications of a theory. Analytical usually involves the user writing down formulas and follow step by step procedures find an answer. They can be used when equations are not complex and an exact answer is

How did Radical Republicans gain control of Reconstruction politics? The Radical Republicans gained control of Reconstruction with the 1866 election. There was violence against freedmen‚ and the Northerners were outraged. The Republicans came up with the 14th Amendment. It gave anyone born in the United States citizenship. This included freed slaves. Numerous Northerners saw the need for tougher methods‚ and supported them. What impact did federal Reconstruction policy have on the former

else. When President Lincoln proposed a plan in this Reconstruction time‚ this plan was the 10% plan. This meant that about 10% of those who voted would have to pledge to the Union their loyalty. Of course this plan was not much of a success and the radicals (Republicans) did not like this. Soon after there was a bill created by congress that was called the Wade Davis Bill. This bill made many (majority) of the southern states take an oath that would have them say they never had any support towards the

booming economy suddenly hit a brick wall. During this time‚ the U.S. experienced several reconstruction episodes. From the Presidential‚ Federal‚ Radical and State/Local reconstruction‚ the two most important reconstruction actions that tool place in my opinion were the Radical reconstruction period and the State/Local reconstruction period. Under the Radical Reconstruction (1865-1867) there were two different things occurring. President A. Johnson assuming office‚ he had his hands full. Albeit his

Mirror and Magnification Equations The mirror equation expresses the quantitative relationship between the object distance (do)‚ the image distance (di)‚ and the focal length (f). The equation is stated as follows: [pic] The magnification equation relates the ratio of the image distance and object distance to the ratio of the image height (hi) and object height (ho). The magnification equation is stated as follows: [pic] These two equations can be combined to yield information about the

The Radical Republicans of Congress did not agree with Johnson and his plans for Restoration. They had different beliefs about the South and started "Radical Reconstruction which committed to civil rights for blacks. The Radicals refused to seat any Senator or Representative from the old Confederacy. Radical Reconstruction included laws that required states to ratify the Fourteenth Amendment in order to be
