Solid-State Ac-Conductivity Analysis For The Long Debated Catalytic Activity Of The Boralite Sieve
(
Qatar University
, 1996 , Article)
The ac-phase dependent impedance, capacitance and dielectric loss of boralite are measured and correlated with those of a similar history HZSM-5 as a function of frequency (0.1-100 kHz) and temperature (373-638 K) at 0.8 ...
Two Forms Of The Backlund Transformation Of A Third Order Differential Equation
(
Qatar University
, 1996 , Article)
Two explicit forms of Backlund transformation of third order dispersive differential equation are derived. The method of derivation depends on the use of a transformation that couples the equation with its modified one.

(
Qatar University
, 1996 , Article)
The structure of the digestive tract of Diplometopon zarudnyi was studied by means of light microscopic histology and PAS reaction. The oesophagus is lined with stratified columnar epithelium while the stomach is lined ...
Improvement Of The Piecewise Approximation Methods
(
Qatar University
, 1996 , Article)
A piecewise approximation method is described for planar curves. The order of classical piecewise approximations is improved. The method exploits the freedom in the
choice of the parametrization and rises the approximation ...
