A rare case of ankyloglossia in a one-humped camel and its successful surgical correction by horizontal to vertical frenuloplasty is reported. Seven-month-old she-camel calf, with a history of excessive salivation and inability to chew and swallow hay, was referred to Al Qattara veterinary hospital. Solid food was regurgitated, whereas milk and water could be swallowed. On examination; the anim...

during rutting period, the male one humped camels, extrudes a balloon like organ from one side of the mouth. twelve heads of the slaughtered one humped camels from different sexes were examined. air was blown through natural openings: mouth, nares, esophagus and trachea. cross and longitudinal sections were made in frozen and formalin fixed specimens. it was concluded that soft palate in one hu...

Persistence of stationary and traveling single-humped localized solutions in the spatial discretizations of the nonlinear Schrödinger (NLS) equation is addressed. The discrete NLS equation with the most general cubic polynomial function is considered. Constraints on the nonlinear function are found from the condition that the second-order difference equation for stationary solutions can be redu...

We describe a novel class of solitary waves in second-harmonic-generation models with competing quadratic and cubic nonlinearities. These solitary waves exist at a discrete set of values of the propagation constants, being embedded inside the continuous spectrum of the linear system (“embedded solitons”, ES). They are found numerically and, in a reduced model, in an exact analytical form too. W...
