Body Wall Morphology of the Sertellid Cheilostome Bryozoan,Reteporellina evelinae

Surgical treatment of a penetrated metallic foreign body in the oral cavity wall of a mare

One of the reasons of weight loss and poor performance in horses is decrease in food intake. Oral cavity problems can cause malfunctions in prehension and deglutition resulting in dysphagia. There are few published reports about a metallic foreign body disorders in the oral cavity of horses due to an important role of their flexible lip and incisor teeth in food selection and prehension. This r...

Management of an Unusual Tracheoesophageal Party Wall Foreign Body

Introduction: Penetration injury to the neck constitutes 5–10% of all trauma cases. Penetration of a foreign body into the trachea with subsequent impaction into the tracheoesophageal party wall is extremely rare. We present a patient with an unusual penetrating injury of the neck caused by a metallic foreign body embedded into the tracheoesophageal party wall, and its management.   Case Repor...

Molecular Simulations of Knudsen Wall-slip: Effect of Wall Morphology

This work involves a molecular simulation study of the phenomena of wall slip occurring in rarefied gases flowing through microand nano-channels. A simulation strategy that mimics a scattering experiment is developed in order to compute the tangential momentum accommodation coefficient ( f) which governs the degree of slip at the wall surface. Noninteracting gas molecules are bombarded at an at...

Viscoelasticity of Holothurian Body Wall

1. Stress-relaxation tests and creep tests were performed on the bodywall dermis of two sea cucumbers, Actinopyga echinites (Jager) and Holothuria leucospilota Brandt. 2. These viscoelastic connective tissues had mechanical properties which agreed well with those of a four-element mechanical model composed of two Maxwell elements connected in parallel. 3. The elastic stiffness of the dermis of ...
