94. Al-Sharh/The Expansion

I/We begin by the Blessed Name of Allah

The Immensely Merciful to all, The Infinitely Compassionate to everyone.

94:01
a. O The Prophet!
b. Have WE not opened up your heart,

94:02
a. and relieved you of your burden,

94:03
a. which had weighed heavily upon your back/mind?

94:04
a. And WE elevated the mention of your name in eminence and fame.

94:05
a. And so it is that with every hardship, indeed, there would always be ease/relief;

94:06
a. with every hardship, indeed, there would always be ease/relief.

94:07
a. So when you get free from routine work,
b. turn to devotion and exert yourself in worship,

94:08
a. and turn towards your Rabb - The Lord in awe and humbleness,
and let HIM be your quest!

Maulana Muhammad Ali - A Strategic Point in Indo-Muslim Politics (Comment)

‘A great man’, says Justice Oliver Wendell, Jr, ‘represents a great ganglion in the nerves of society, or to vary the figure, a strategic point in the campaign of history, and part of his greatness consists in being there’. (italic ours). And Maulana Muhammad Ali was one such nerve-centre in Indo-Muslim society during the second and third decades of the twentieth century. Indeed, he was one such strategic point in the onward march of Indo-Muslim politics that eventually found culmination and crystallization in the emergence of Pakistan. Actually no one else represented the tone, tenor and temper of the romanticist, Khilafatist era (in the 1910s and 1920s) as he did in his hectic life, his revolutionary activities his numerous discomfitures, and in his tragic death. Whether he led a hectic life, whether he took recourse to a revolutionary path, or whether he goaded himself to die a tragic death outside the frontiers of his motherland cataclysmically, in whatever he did, he, consciously or unconsciously, carried forward the campaign of Indo-Muslim history: the redemption of Islam in India and abroad. In other words, he stood, above all, for an honourable existence for Muslims in India and in the rest of the troubled Muslim world in the existential crisis that convulsed Muslim India and that world.

Theoretical Investigation of Dynamic Processes in Thermally Insulated Liquid Chromatographic Columns of Cylindrical Geometry

Liquid chromatography is a separation and purification process that has attracted attention due to its wide usage in biological, biochemical, fine chemicals, pharmaceutical and food processing industries. The task of this dissertation is focused on the theoretical study of linear and nonlinear liquid chromatographic processes in thermally insulated cylindrical columns packed with either fully-porous or core-shell particles and operating under either isothermal or non-isothermal conditions. Both non-reactive and reactive chromatographic processes are analyzed. In the latter case, separation and conversion of the reactants into products takes place concurrently. A two-dimensional general rate model (2D-GRM) in cylindrical coordinates is formulated to simulate these processes. For the simulation of linear chromatography, the finite Hankel and the Laplace transformations are applied one after another to obtain analytical solutions of the linear model equations for two different sets of boundary conditions. To further elaborate the process, the analytical temporal moments are obtained from the Hankel-Laplace domain solutions. These moments are very useful for analyzing the retention times, band broadenings and front asymmetries of elution profiles. The derived analytical solutions and moments are very useful for diluted or small volume samples. However, to simulate chromatographic process for concentrated or large volume samples, the numerical approximations of nonlinear model equations are needed. In this thesis project, a high-resolution finite volume scheme (HR-FVS) is extended and applied to solve the resulting 2D-model equations in cylindrical coordinates. Several case studies are conducted for a wide range of thermodynamic, kinetic and reaction coefficients. Furthermore, the coupling between concentration fronts and thermal waves are demonstrated through graphs and essential parameters influencing the column (or reactor) performance are pinpointed. A few consistency tests are also conducted for assessing the process performance. The solutions obtained are useful tools for analyzing, optimizing and upgrading the liquid chromatographic processes.
