The history of cardiac surgery is associated with great surgeons, and their contributions are usually recognized by having their names attached to the innovation. Such is the case for many instruments (DeBakey forceps, Cosgrove retractor, and others), sutures (Lima suture for off-pump coronary artery bypass, Dubost suture for left ventricular aneurysm), and operations (Rastelli, Mustard, Batist...

Brazilian Journal of Cardiovascular Surgery This historical issue kicks off celebrations after 30 years of continuous publication of the Revista Brasileira de Cirurgia Cardiovascular, known today as the Brazilian Journal of Cardiovascular Surgery (BJCVS). These 30 years represent the history of our Society. The journal was founded by idealists led by Dr. Adib Jatene, and they represent the pion...

Braz J Cardiovasc Surg | Rev Bras Cir Cardiovasc he last 12 months have been of deep losses for the Brazilian cardiovascular surgery. Distinguished and competent professionals, fundamental to the consolidation and advancement of the specialty in our country have left us, after serving brilliantly their career in this world. On July 10, 2014, Dr. Geraldo Verginelli died. On November 12, 2014, Dr...

(p. 142); the meaningless Arabic 'rs proves to be a corruption of the name of the Lydian city of Daldis (p. 196); the obvious error of translating pi'sos "peas", as aruzz, "rice", is quite plausibly explained in terms of a corruption in the Greek text available to the Arabic translator (p. 196). One is frequently struck by unexpected ways in which Arabic translators took their own vocabulary to...

In this paper, we consider a multi-server queuing system in which additional servers are allowed for a longer queue to reduce the customer’s balking and reneging behavior. The customers are assumed to arrive in Poisson fashion and their service- times follow exponential distribution. The number of servers in long run depends on the queue-length. We obtain equilibrium queue size distribution. Th...

The object of the investigation is to study reducible $M$-ideals in Banach spaces. It is shown that if the number of $M$-ideals in a Banach space $X$ is $n(<infty)$, then the number of reducible $M$-ideals does not exceed of $frac{(n-2)(n-3)}{2}$. Moreover, given a compact metric space $X$, we obtain a general form of a reducible $M$-ideal in the space $C(X)$ of continuous functions on $X$. The...
