We report a unique case of a 12-year-old girl with unilateral proptosis form orbital extension of an extensive bilateral cephalhematoma. Loss of vision in the left eye due to severe proptosis was reversed by prompt aspiration and tarsorrhaphy.

Orbital chondrosarcomas are extremely rare and are usually an extension of tumours involving the paranasal sinuses. A unique case of dedifferentiated chondrosarcoma arising solely within the orbit is presented.

We study ground state properties of the Kondo lattice model with an electron–phonon interaction. The is proved to be unique; in addition, total spin determined according structure. To prove assertions, extension method reflection positivity given terms order preserving operator inequalities.

We discuss resource-bounded measures on the class of recursive structures and prove that with respect to such measures a random recursive structure is almost surely isomorphic to the unique countable model of the extension axioms.

The unique continuation on quadratic curves for harmonic functions is discussed in this paper. By using complex extension method, the conditional stability of along illustrated. numerical algorithm provided based collocation method and Tikhonov regularization. estimates parabolic hyperbolic are demonstrated by examples respectively.

The study assessed the perceived effectiveness of agricultural extension methods used to disseminate improved technologies to rice farmers in kogi state, Nigeria. The specific objectives were to describe the socio – economic characteristics of the rice farmers, to assessed farmers level of contact with extension agents, perceived level of competence of extension agents to perform agricultural e...

The purpose of this study was to assess the process of extension program development in Iranian Agricultural Extension System (IAES). The research instrument was a structural questionnaire with close-ended questions which its validity and reliability was confirmed by using expert panel and Cranach’s alpha test, respectively. The target population of this research included all extension managers...

for a graph $g$ let $gamma (g)$ be its domination number. we define a graph g to be (i) a hypo-efficient domination graph (or a hypo-$mathcal{ed}$ graph) if $g$ has no efficient dominating set (eds) but every graph formed by removing a single vertex from $g$ has at least one eds, and (ii) a hypo-unique domination graph (a hypo-$mathcal{ud}$ graph) if $g$ has at least two minimum dominating sets...

The limited audio bandwidth of narrowband telephone speech degrades the speech quality. This paper proposes a method that extends the bandwidth of telephone speech to the frequency range 0–300 Hz. The lowest harmonics of voiced speech are generated using sinusoidal synthesis. The energy in the extension band is estimated from spectral features using a Gaussian mixture model. The amplitudes and ...
