Tricho-rhino-phalangeal syndrome type I (TRPS I) is characterized by a bulbous nose, sparse hair and epiphyseal coning. Autosomal dominant and recessive transmission are suggested. The presence of cone-shaped epiphyses, the major complaint of patients due to swelling over the phalangeal joints, requires differential diagnosis among various syndromes. This paper, describing a ten-year-old girl w...

introduction: tympanoplasty is the standard and well established procedure for closure of tympanic membrane perforations .this paper compares the results of tympanoplasty in terms of hearing improvement and graft incorporation in patients with chronic perforation of the tympanic membrane between two groups with and without active drainage at the time of surgery.  materials and methods: sixty re...

introduction: nodular fasciitis is described as a benign reactive proliferation of myofibroblasts. due to its rapid-growing nature, a precise clinical diagnosis is difficult and the condition is frequently misdiagnosed as malignant lesions.   case report: in this study, we present the case of a young woman with an auricular nodular fasciitis as an example of one of the rarest sites of this tumo...

In this paper, new attitude maneuver using non-holonomic turn is proposed. The essence of this turn is characterized by an under-actuated system which does not have a direct torque device around the intended axis is made through what we call a coning motion. It is well known that falling cat motion utilizes non-holonomic turn. This paper shows the motion structure interpretation, in which a ver...

The problem of a spacecraft tracking a desired trajectory is defined and addressed using adaptive feedback control. The control law, which has the form of a sixth-order dynamic compensator, does not require knowledge of the inertia of the spacecraft. A Lyapunov argument is used to show that tracking is achieved globally. A simple spin about the intermediate principal axis and a coning motion ar...

Neurological deterioration sometimes follows removal of cerebro-spinal fluid by lumbar puncture below a spinal block caused by a tumour. Experience has shown that similar impaction of a spinal intradural tumour may occur following the draining of hydrocephalus. We have used the term "upward spinal coning " to describe this and report four cases in which impaction of an intradural metastasis occ...
