stories, legends and myths in among various nations have similar factors which can be the subject of different researches and analysis. the search of perfection and model of ideal man is one of these factors. truly mantiq al-tair by attar-e-neishaburi is the most beautiful symbolic works of the east in this field (search of perfection) which has been imitated by many of writers and poets in all...

The analogical description of a shape may be helpful in better understanding of anatomical structures during imaging. Seagull is a popular name for a seabird with a heavy body and two long wings. The “seagull sign ”has been used in cardiology for evaluation of the mitral valve and in orthopedics for erosive osteoarthritis.[1-3] On a plain X-ray abdomen, a triradiate collection of a dark shadow ...

The seagull terms for the electric polarizability of the nucleon are shown to vanish indeed, if one introduces fluctuations around the Skyrmion configuration, and after all the origin of the electric polarizability cannot be attributed to the seagull terms in the Skyrme model.

The full Hamiltonian of the soliton models contains no electric seagull terms. Here it is shown that if one restricts the fields to the collective subspace then electric seagull terms are induced in the effective Hamiltonian. These effective seagull contributions are consistent with gauge invariance. They also reproduce the leading nonanalytic behavior of a large Nc chiral perturbation theory c...

Ohta proposed a solution for the well-known difficulty of satisfying the WardTakahashi identity for a photo-meson-baryon-baryon amplitude (γMBB) when a dressed meson-baryon-baryon (MBB) vertex function is present. He obtained a form for the γMBB amplitude which contained, in addition to the usual pole terms, longitudinal seagull terms which were determined entirely by the MBB vertex function. H...

The non-resonant (seagull) contribution to the nuclear Compton amplitude at low energies is strongly influenced by nucleon correlations arising from meson exchange. We study this problem in a modified Fermi gas model, where nuclear correlation functions are obtained with the help of perturbation theory. The dependence of the mesonic seagull amplitude on the nuclear radius is investigated and th...

Efficient information sharing is difficult to achieve in the scenario of emergency and rescue operations because there is no communication infrastructure at the disaster sites. In general, the network condition is relatively reliable in the intra-site environment but relatively unreliable in the inter-site environment. The network partitioning problem may occur between two sites. Although one c...

The aim of this study was to examine antibiotic resistance (AR) dissemination in coastal water, considering the contribution of different sources of fecal contamination. Samples were collected in Berlenga, an uninhabited island classified as Natural Reserve and visited by tourists for aquatic recreational activities. To achieve our aim, AR in Escherichia coli isolates from coastal water was com...
