Prolapse of the penis through an iatrogenic incision on the right side of the preputial base in a five year old dromedary camel was handled surgically and the organ was successfully replaced into the preputial cavity. The condition occurred as a result of draining an abscess at the base of the prepuce by a quack about eight months earlier. The reason to report this case lies in its peculiarity ...

Pulpal respiration in second and third premolar dog teeth was measured by a radioisotope tracer determination. Dental amalgam, a zinc oxide and eugenol base, and a calcium hydroxide base were placed into a cavity preparation. Following a two-week period the teeth wer~ extracted intact. The pulp tissue was removed and suspended in a phosphate buffer saline solution (PBS) which 14C-succinic acid ...

Particle beam therapy has been rapidly developed in these several decades. Proton and carbon ion beams are most frequently used in particle beam therapy. Proton and carbon ion beam radiotherapy have physical and biological advantage to the conventional photon radiotherapy. Cancers of the skull base, nasal cavity, and paranasal sinus are rare; however these diseases can receive the benefits of p...

Chondromas are benign tumors that may be found in many parts of the body. Among intracranial neoplasms, tumors of cartilaginous origin are rare. It has been shown that most of these tumors arise from the skull base. Their occurrence in other parts of the intracranial cavity is unusual. Chondroma of falx is a rare neoplasm. In this report we introduce a case of falcine chondroma arose from front...

OBJECTIVE We evaluated postoperative changes in nasal cavity volume and their effects on nasal function and symptoms after endoscopic endonasal transsphenoidal approach for antero-central skull base surgery. STUDY DESIGN Retrospective chart review at a tertiary referral center. METHODS We studied 92 patients who underwent binostril, four-hand, endoscopic endonasal transsphenoidal approach s...

Cavity filters are a necessary component in base stations used for telecommunication. Without these filters it would not be possible for base stations to send and receive signals at the same time. Today these cavity filters require fine tuning by humans before they can be deployed. This thesis have designed and implemented a neural network that can tune cavity filters. Different types of design...

Subfrontal schwannomas are rarely reported. They are usually found only in the subfrontal area, but some extend to the nasal cavity. In these cases, prevention of postoperative cerebrospinal fluid (CSF) leakage through thinned or eroded anterior skull base is important. A 51-year-old female with anosmia and mild nausea was diagnosed as subfrontal extraaxial mass with nasal cavity extension. Thi...

The effects of Single Walled Carbon Nanotube (SWCNT) on mixed convection in a cavity are investigated numerically. The problem is studied for different Richardson numbers (0.1-10), volume fractions of nanotubes (0-1%), and aspect ratio of the cavity (0.5-2.5) when the Grashof number is equal to 103. The volume fraction of added nanotubes to Water as base fluid are lowers than 1% to make dilute ...

A one-pot cyclisation/oxidation process results in a new constrained-cavity Schiff-base dipyrrin macrocycle and allows access to Li, Fe, Zn complexes of this unique chromophore.
