A MASTOID GUIDE AND SEPARATOR.

A Dynamic Separator Algorithm

Our work is based on the pioneering work in sphere separators done by Miller, Teng, Vavasis et al, [8, 12], who gave efficient static (fixed input) algorithms for finding sphere separators of size s(n) = O(n d−1 d ) for a set of points in R. We present dynamic algorithms which maintain separators for a dynamically changing graph. Our algorithms answer queries and process insertions and deletion...

Triboelectric Separator with Mixing Chamber and Pre-Separator

A Weighted Planar Graph Separator

Given a weighted planar graph, we construct a simple separating cycle C whose interior and exterior both weigh at most 2/3 of the total weight. The cycle C uses k jumps across the faces and ordinary edges with cost O(1=k) of the total edge cost. This theorem is the main component of a PTAS for the weighted TSP problem 4].

A Simple and Inexpensive Evaporator Entrainment Separator

Use of angle iron separators in two evaporator vessels at Darnall resulted in a marked reduction in entrainment rates. Efficiencies in excess of 90% were observed with negligible pressure differential across the separator. Separator efficiency can be evaluated rapidly by using a centrally based Auto-Analyser. Introduction To avoid sugar losses by entrainment, all evaporator vessels are fitted w...

Congenital Cholesteatoma Localized to the Mastoid Cavity and Presenting as a Mastoid Abscess

Introduction. Congenital cholesteatoma is a pearly white mass that rarely originates from the mastoid process. Case Report. A 21-year-old male patient presented to our department with severe right mastoid pain and postauricular fluctuant swelling for 23 days. There was no preceding history of ear complaints and examination showed a normal right ear drum. Emergency exploration of the mastoid pro...
