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...

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...

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...

background: several studies have showed an increased prevalence of airflow obstruction in first degree relatives of individuals with chronic obstructive pulmonary disease (copd). considering no specific research had evaluated airway resistance in offspring of patients with severe copd, we utilized a spirometry and a impulse oscillometry (io) to evaluate this population. materials and methods: i...

background and aim: the video head-impulse test (vhit) measures the vestibulo-ocular reflex (vor) driven by each semicircular canal, follo­wing high-acceleration head rotations. the main measurable response is the ratio of eye mov­ement velocity to the angular head velocity, which reflects canal function. although norma­tive data is available for vor gain, most studies only report horizontal vo...
