Aircraft engines constitute a comp‌lex system, requiring adequate mon-itoring to ensure flight safety and timely maintenance. The best way to achieve this, is modeling the engine. Therefore, in this paper, a suitable mathematical model from engine controller design point of view, for a specific aero turbine engine is proposed by the aid of MATLAB/Simulink software. The model is capable of reduc...

BACKGROUND Planning the surgical strategy for a gastrointestinal stromal tumor (GIST) at the posterior wall of the lower rectum is difficult, as the procedures for the lower rectum are hampered by poor visualization and may cause anal dysfunction or discomfort. We report a novel procedure to resect a submucosal tumor of the rectum. CASE PRESENTATION A 75-year-old woman presented with metrorrh...

OBJECTIVE To compare laparoscopic distal pancreatectomy (LDP) versus open distal pancreatectomy (ODP) by using meta-analytical techniques. BACKGROUND LDP is increasingly performed as an alternative approach for distal pancreatectomy in selected patients. Multiple studies have tried to assess the safety and efficacy of LDP compared with ODP. METHODS A systematic review of the literature was ...

Reliability of a hybrid renewable energy system (HRES) strongly depends on various uncertainties affecting the amount of power produced by the system. In the design of systems subject to uncertainties, both deterministic and nondeterministic design approaches can be adopted. In a deterministic design approach, the designer considers the presence of uncertainties and incorporates them indirectly...

In a recent edition of this journal, Mannion and Braithwaite provide a succinct analysis of the emergence, and ultimately limited impact, of what they term the current ‘Safety I’ movement in healthcare. They describe the arc of this field from denial, through engagement via mechanisms and approaches imported from other industries, to the current situation where, despite ‘best efforts,’ error ra...

We compared the efficacy and safety of a biosimilar form of beta-interferon-1a (Actovex) versus the reference product in the treatment of relapsing remitting multiple sclerosis (RRMS). In a double blind, randomized phase 3 clinical trial, we evaluated 138 patients with RRMS that were allocated to receive the biosimilar medication and the reference treatment (30 μg intramuscular, weekly for one ...
