Acquired subglottic stenosis (a SGS) continues to pose great challenge to patients and clinicians due to lack of effective treatment strategies. Our understanding in pathophysiology of a SGS has significantly advanced in the past decades; however, much still remains to be elucidated. The purpose of this review is to describe current state of research in acquired subglottic stenosis, and discuss...

The huge supergiant shell (SGS) LMC4, next to the giant H II region 30Doradus the second most impressive feature of the Large Magellanic Cloud (LMC), has been the subject of many studies and was used to test various models of star forming mechanisms. In this paper we present a B,V photometry of the very centre of this SGS. The new data yield an age of 11(2) Myr and a B−V excess of 0.10(3) mag. ...

We derive a minimal generating set of planar moves for diagrams surfaces embedded in the four-space. These appear as bonded classical unlink diagrams.

One of the recent strategies for increasing the customer’s loyalty in banking industry is the use of customers’ club system. In this system, customers receive scores on the basis of financial and club activities they are performing, and due to the achieved points, they get credits from the bank. In addition, by the advent of new technologies, fraud is growing in banking domain as well. Therefor...

SGS implemented two rules-based fuzzy logic expert applications on two grinding circuits operated by Peñoles Group in Mexico. Both expert systems are based on control strategies that push against process constraints to improve throughput. Based on proven methodologies, the projects also required some new approaches that led to permanent changes to the mill control strategy. This paper provides ...

It is well known, and was first proved by Sylow (1872), that every group of prime-power order p has a presentation of the form {a1, . . . , an | api = vii, 1 ≤ i ≤ n, [ak, aj ] = vjk, 1 ≤ j < k ≤ n}, where vjk is a word in the elements ak+1, . . . , an for 1 ≤ j ≤ k ≤ n . A presentation of this form is now called a power-commutator presentation for the group and written briefly {A | R} . As was...
