Individual Interpretation

One fresh contribution to the contemporary study of fiqh (Islamic jurisprudence) is the theory of limits (nazariyyah al-hudud) promoted by a Syirian liberal Islamic figure, Muhammad Syahrur. Syahrur’s theory of limits solves the epistemological deadlock of previous works. Syahrur asserts that the theory of limits is an approach within ijtihad (individual interpretation) to study the muhkamat verses (clear and direct verses of law) of the Qur’an. The term “limit” (hudud) used by Syahrur refers to the meaning of “the bounds or restrictions of God which should not be violated, contained in the dynamic, flexible, and elastic domain of ijtihad. By using the theory of limit, Syahrur tries to re-constructs both concept poligamy and jilbab as contribution to the contemporary study of Islamic jurisprudence.

Fluorescein Molecule

Electro-optical parameters of fluorescein molecule in the second excited electronic state and information on the interactions with solvents were obtained from a solvatochromic study. Parameters of the solvents such as the refractive index, electrical permittivity and Kamlet-Taft parameters (hydrogen bond acidity and basicity) were related with the experimentally recorded shifts of UV absorption spectral band of fluorescein dissolved in several solvents. Through a variational method, the electric dipole moment and polarizability in excited state of fluorescein molecule were estimated. The calculus requires some parameters of the fluorescein molecule in the ground electronic state, which were determined through a quantum-mechanical study.

AbstractThe mass eigenvalue equation for mesons in nonlinear spinor theory is derived by functional methods. In second order it leads to a spinorial Bethe-Salpeter equation. This is solved by a variational method with high precision for arbitrary angular momentum. The results for scalar mesons show a shift of the first order results, obtained earlier. The agreement with experiment is improved thereby. An excited state corresponding to the η' is found. A calculation of a Regge trajectory is included,too.
