cardiac conduction system enables the heart to pulsate continuously by producing electric impulse and conducting it. as the anatomical information about cardiac conduction system in human being and other mammals needed in various fields of sciences, such as anatomy, histology, physiology, pathology and cardiology, the present review article intends to provide this basic information about an imp...

In this article, the first experimental demonstration of a non-iterative electronic dispersion compensation (EDC) solution implemented at transmitter using finite impulse response (FIR) filter optimized with Gerchberg-Saxton (GS) algorithm, is presented, for intensity-modulation and direct-detection (IM/DD) systems. The theoretical framework preliminary simulations have been presented in Part I...

No consensus has been reached on how musculoskeletal system injuries or aging can be explained by a walking plantar impulse. We standardize the plantar impulse by defining a principal axis of plantar impulse. Based upon this standardized plantar impulse, two indexes are presented: plantar pressure record time series and plantar-impulse distribution along the principal axis of plantar impulse. T...

the efficiency of a collar in reducing the scour depth around circular and rectangular piers is studied at different flow intensities (ratio of upstream shear stress to sediment critical shear stress). rectangular piers aligned with the flow as well as skewed at 5º, 10º, 20º were examined. previous studies had shown that with collar the equilibrium time of scouring increases considerably. to re...

A rectangular drawing is a partition of a rectangle into a set of rectangles. Rectangular drawings have many important applications including VLSI layout. Since the size of rectangular drawings may be huge, compact encodings are desired. Several compact encodings of rectangular drawings without degree four vertices are known. In this paper, we design two compact encodings for rectangular drawin...

Due to the special (procedural) nature of the language (verbal communication) ‘knowledge’, the dominant trends in applied linguistics research in the last few decades have been advocating ‘acquisition’ rather than ‘learning’ activities where the main focus in SL & FL education should be on ‘meaning’ while some ‘focus-on-form’ being justified. But the ‘form’ to be ‘focused-on’ is mostly misconce...

background: indian tea industry workers are exposed to various exposures at their workplace. objective: to investigate the respiratory health of indian tea industry workers. methods: we administered a respiratory questionnaire to and measured lung function in workers of 34 tea gardens and 46 tea factories. we used correlation matrices to test the association between their respiratory symptoms a...

abstract:this study examines the significant impact of exchange rate shock on prices of malaysian importsand exports. in methodology, the study adopts vector error correction (vecm) model using monthlydata of nominal exchange rates, money supply, prices of imports and prices of exports covering theperiod of m1:1999 to m12:2006. for further analysis, we adopt an innovation accounting bysimulatin...
