The adequate evaluation of new technologies in productive systems that perform multiple and simultaneous processes, exploring the intense sharing of resources, demands the updating of supervision and control systems. On the other hand, totally infallible systems are unviable, and for a flexible productive system (FPS) does not to suffer interruptions due to component failure, the concept of AFT...

Rapid diagnosis and treatment of acute community-acquired bacterial meningitis reduces mortality and neurological sequelae, but can be delayed by atypical presentation, assessment of lumbar puncture safety, and poor sensitivity of standard diagnostic microbiology. Thus, diagnostic dilemmas are common in patients with suspected acute community-acquired bacterial meningitis. History and physical ...

Although early texts state that 2 “the mechanism of the positive column is fairly well understood”, Chapman warns us 4 that, “We should heed the warning of Cobine (1958) ......., that no sources are infallible, that all proofs should be questioned, and that no discharge phenomena are so well understood that data can be applied precisely.” On the face of it, the Ip-VC curve in our experiments is...

We would like ideally to determine whether power is indeed sexy, or whether sexiness is powerful. We here describe the most rigorous (though hardly infallible) methods for constructing models to answer such a question that we could estimate. The approach used depends on whether we are treating women’s status and sexiness as in question, or men’s, since we found individual status to be related t...

Human brucellosis still presents difficulties in diagnosis and prevention. Townspeople may be infected by drinking raw milk while on holiday. Laboratory tests are still unsatisfactory as indicators of clinically active disease. High titre antibodies may be found without overt symptoms, particularly in persons occupationally exposed to repeated infection. In contrast, cases have been recorded in...

The repeated stresses the capital markets have experienced over the past decade have caused many financial planners to question all they thought they knew about invest­ ment management. Modern portfolio theory (MPT) and its core component strategies. asset allocation and rebalanc­ ing-indeed. any investment strategy not involving cash in mattresses-came under attack. After experiencing Signific...

There are many metrics designed to assist in the performance debugging of large-scale parallel applications. We describe a new technique, called True Zeroing, that permits direct quantitative comparison of the guidance supplied by these metrics on real applications. We apply this technique to three programs that include both numeric and symbolic applications. We compare three existing metrics: ...

Of all the roentgen examinations, that of the chest is best. Its position is the easiest; it seldom requires contrast media, it is by far the most productive in demonstration of abnormalities; and with the exception of bone films it offers the greatest detail. It has been such a tremendously important tool to medicine that there is a tendency to consider it infallible. However, in the compariso...

The electronic and structural properties of pristine and carbon doped (C-doped) boron nitride nano-ribbons(BNNRs) have been studied employing density functional theory (DFT) calculations. Total energies, gapenergies, dipole moments, and quadrupole coupling constants (qcc) have been calculated in the optimizedstructures of the investigated BNNRs. The results indicated that the stability and gap ...
