This is one of the fundamental documents of our time, a period characterized by the concepts of 'information' and 'communica­ tions'. Norbert Wiener, a child prodigy and a great mathematician, coined the term 'cybernetics' to characterize a very general science of 'control and communication in the animal and machine'. It brought together concepts from engineering, the study of the nervous syste...

This paper describes two steam turbine governor valve failures in the same installation, the troubleshooting that determined the root cause, and the new valve designed to prevent similar failures. The original governor valve design had been used successfully for many years in large multistage, multivalve steam turbines, but apparently was not reliable at the high steam pressures employed today....

heat, has been known to man since 2500 BC, when it was already being used by Finnish potters. The Greeks called it asbestos meaning “inextinguishable,” and this is the name still used today in many languages. The first known patent for asbestos was issued in the United States of America in 1828 covering its use as an insulating material in steam engines. The first asbestos textile factory start...

This study examined whether hydrotherapy per formed in bubble baths improves knee range of motion in patients who have undergone total knee arthroplasty. The subjects included 11 patients (two males and nine females) who underwent unilateral total knee arthroplasty. In this study, we measured knee range o f motion test results preand post-bubble bath. The mean di fference in range o f motion te...

Turbine overspeed events lead to the most dangerous and costly of catastrophic turbine failures. Traditionally, overspeed protection systems were designed and provided by the original equipment manufacturers (OEMs)—few options were available either in terms of testing or modifying these systems. With new turbines, and with the retrofit of older systems, it is more common to see third party syst...

A study was carried out to determine if the presence of bacitracin methylene disalicylate (BMD) interfered with the assay of chlortetracycline (CTC) and if the presence of CTC interfered with the assay of BMD when both are combined in a pig feed. In addition, the potential influence of steam pelleting on active concentrations of BMD and CTC was determined. Further, the stability of BMD in the p...

This paper introduces a kind of diagnosis principle and learning algorithm of steam turbine fault diagnosis which based on Elman neural network. Comparing the results of the Elman neural network and the traditional BP neural network diagnosis, the results shows that Elman neural network is an effective way to improve the learning speed , effectively suppress the minimum defects that the traditi...

Performance responses to steam flaking flint corn as well as to the addition of roughage to finishing diets composed of whole flint corn were evaluated. Ninety-six Nellore bulls were stratified by initial BW (373 ± 11 kg) and randomly allotted to 16 feedlot pens (6 bulls/pen) in a randomized complete block design with 4 replicates/treatment. Dietary treatments for the 86-d feeding trial consist...

Pentingnya memberikan ASI telah memiliki bukti kuat(1). Namun kenyataanya, banyak kendala dalam penerapanya(2). Data menunjukkan bahwa pemberian eksklusif di Indonesia sebesar 89,4%(2020). Salah satu penyebabnya stres yang dialami ibu akan menghambat pelepasan hormon oksitosin, jika terjadi refluks oksitosin terhambat akibat adrenalin oleh mempengaruhi produksi ASI(3). Faktor fisik komplikasi a...

In Unani System of Medicine, the concept Zightuddam Qawi (Hypertension) is described under heading Imtila (Congestion fluid in body) by many physicians. Hypertension basically a disease blood vessels which have elevated pressure. The possible causes this mentioned system medicine are Sue Mizaj Damvi (abnormal sanguineous temperament), Sauda-e-Muhatriqa (burnt melanin) and Haar Yabis (hot dry te...
