Introduction: Different surgical techniques used for closure of various oral defects. While each one of these techniques has its limitation; the buccal pad of fat used in last quarter of last century as pedicle or free graft in reconstruction of small to medium, congenital and acquired defects showed good potentials for success. The present study used the BPF as pedicled flap to reconstruct intra oral defects. The study aimed to evaluate of the success of buccal pad of fat pedicled flap in the reconstruction of intra oral defects. Outlining its indications, limitations and complications. Materials and Methods: The study included 19 patients (17 males and 2 females) with age range between (1- 70 years), all patients were treated with pedicled BPF for intra oral defects (8 pts. with oro-antral communications, 5pts. with maxillary alveolar bone defects, 4 pts. with cleft palate, and 2 pts. with carcinoma of buccal mucosa), under general or local anesthesia. Follow-up period was for 3 months post-operatively, Results:The results showed that 94.7% of patients had complete epithelization of flap and complete closure of the defect within 4-6 weeks. Only 1 pt. 5.3% had total flap loss with very small size of the BPF. In postoperative period, 5.3% of pts. complained from pain, trismus, vestibular obliteration, partial flap loss, all disappeared gradually within 1 month from the reconstruction. Conclusion:The BPF is reliable, easy, safe method to reconstruct small and medium size intra oral defects of maximum size 5x4x3 cm, in maxilla from upper canine region to the soft palate, and in buccal mucosa from retro molar area to the commissure of the mouth. Key words: BPF, intra oral defects, reconstruction.

The Lq-HAM is a combined form of q-homotopy analysis method (q-HAM) and Laplace transform. The aim of utilizing the Laplace transform is to outdo the shortage that is mainly caused by unfulfilled conditions in the other analytical methods. The results show that the analytical solution converges very rapidly to the exact solution.
In this study the melting point and hardness of the paraffin wax was improved by mixing it with 1:1 ratio of micro crystalline wax then adding weight percentage wt% of locally produced nano particles (CuO,ZnO,AI2O3 and bentonite ) for each addition to the wax mixture. The results showed an increase in the melting point and hardness values of the prepared samples by increasing the weight percentage of each nano particles additives. . It was found that the addition of nano bentonite to the wax mixture gave high melting point values (122.5°C)and hardness (81.2)followed by melting point value (97°C)and hardness(68.2)resulting from the addition of CuO nano particles to the wax mixture compared to other used nano particles.
As a star explode as a supernova its ejecta will directly interact with relativelylow density interstellar medium with high shock wave velocity, and due to thisinteraction many of forbidden emission lines will give a raise from both theexcitation and ionization of the atom in the region. So, the study of these emissionlines can reveal many physical properties of the region, in this case the remnant ofthe supernova, such as temperature, density, composition, and many other importantphysical processes. In this paper the optical spectrum of the young galacticsupernova remnant which is the Crab Nebula has used, in order to calculate it’selectron temperature (Te) and electron density (ne) by using the [OIII] and [SII]forbidden lines.

Nuclear shell model is adopted to calculate the electric quadrupole moments for some Calcium isotopes 20Ca (N = 21, 23, 25, and 27) in the fp shell. The wave function is generated using a two body effective interaction fpd6 and fp space model. The one body density matrix elements (OBDM) are calculated for these isotopes using the NuShellX@MSU code. The effect of the core-polarizations was taken through the theory microscopic by taking the set of the effective charges. The results for the quadrupole moments by using Bohr-Mottelson (B-M) effective charges are the best. The behavior of the form factors of some Calcium isotopes was studied by using Bohr-Mottelson (B-M) effective charges.
Flexible pipes, such as GRP pipes, serve as effective underground infrastructure especially as sewer pipeline. This study is an attempt for understanding the effects of bedding types on the behavior of large diameter GRP flexible sewer pipes using three dimensional finite element approaches. Theoretical and numerical analyses were performed using both BS EN 1295-1 approach and finite element method (ABAQUS software). The effects of different parameters are studied such as, depth of backfill, bedding compaction, and backfill compaction. Due to compaction, an increase in the bedding compaction modulus (E’1) results in a reduction of both stresses and displacements of the pipe, especially, for well compacted ba
