أُجريت الحسابات النظرية باستخدام نظرية التابعية للكثافة و بالطريقتين نصف التقربية و initio-Ab لمادة الصباغ الليـزري البـايرومثيين و المركبـات المرتبطـة بـه chromophore-PM, 4m-PM .PM597, PM567, PM 650, PM546, أجرينا الحسابات النظرية باستخدام DFT, AM1, DFT- TD و CIS للسوية الأرضية و المثـارة الأولى لمواد صبغات ليزر منتقاة. و حصلنا على الهندسة المثلى للجزيئات و طيف UV و IR و الانتقال بين السوية الأرضية S0 و المثارة S1 فضلاً عن HOMO و LOMO و خواص أخرى.
Theoretical calculations using density functional theory (DFT) both on semi empirical and Ab initio levels have been carried out for pyrromethene laser dye and related compounds (PM-chromophore, PM-4m, PM 546, PM650 PM 567 and PM597). We carried out theoretical calculations using DFT, AM1, TDDFT and CIS on ground and excited states for the selected laser dye materials, we obtained the optimized geometry of the molecules, UV, IR spectrum, and the transition between the ground S0 and the first excited S1 states exclusively, the HOMO and LUMO states and other properties.

In this work, theoretical calculation of the ground and excited state of
coumarin compounds are performed using DFT-B3LYP and CIS methods with
6-31G basis set. IR spectrum, UV/Vis spectrum, molecular orbitals and energy
gap are calculated. We use
different solvents ethanol, methanol, water,
acetonitrile (ACN), dimethyl sulfoxide (DMSO), acetone, and dichloromethane
to compare values of UV/Vis absorption spectra. Then the calculated results are
compared with the experimental values.
We have used numerical methods to solve the Kohn-Sham equations of the
Density Functional Theory DFT, within local density approximation LDA
employing different pseudopotentials in order to obtain equilibrium structure
and properties of some mater
ials (namely Si, Cu, and Ni). We used in these
calculations a number of pseudopotentials in order to obtain the most accurate
results, and we varied the computational procedure by choosing different Kpoint
sampling and different numerical methods for the same purpose.
The results we have obtained from these ab initio calculations are in good
agreement with experimental results, which allows us to use the same
techniques for further study of some properties of materials.
In this research, we studied the quantum effect of the electronic
density change effect of some sodium( Nan) clusters properties,
electronic and spectral properties changes.We have been studied
using density functional theory: (DFT/B3LYP(6-311+G(2d))).
Density Functional Theory (DFT) is a computational method that
derives properties of The sodium clusters (neutral and positively)
based on a determination of the electron density of the clusters.
Thirty-two patients with port-wine stain were included in this study. The 585 nm
pulsed dye laser treatment with an air cooling device was repeated 4 times at 8 – week
intervals with a setting of 0.5 ms pulse duration and an average energy fluence
5 - 6.5 J/
cm2, using 7 mm spot size.
The results revealed improvement of port-wine stains after multiple treatments , and
69% of the patients achieved good or excellent clearance after the fourth treatment.
Transient purpura and tolerable pain were noted immediately after each treatment (87.5%),
crusting (25%), hypopigmentation (9%), hyperpigmentation (6%) were also mild and their
occurrence didn’t increase by repeating treatment.
The results of this study indicated that the 585 nm PDL is effective and well tolerated
in the treatment of port wine stain.
The management of electronic documents is considered as one of
the most important problems that have been discussed in this age.
That is due to its effectiveness and significance in providing a
variety of services in different governmental departm
ents. Therefore it was necessary for many countries to rely on an electronic documents management system.
Even such systems have many advantages, but they have also some cons such as the application inability in all foundations, incapability of sharing data between the foundations except through a middleware, difficulty of following up the dealings by their owner, etc. These problems are due to the absence of a generic and uniform structure between foundations. Such structure may lead to an incorporation and collaboration between these foundations. In this paper, we have made an analytical study for some systems showing their cons, then we have proposed an algorithm for following up any dealings regardless of their type or the department which will manage it. Then we proposed a design for a dynamic database which could be expanded according to the foundation's needs.
