conclusions: left ventricular systolic heart failure, may result in inter and intra-atrial asynchrony even in clinically stable patients without significant pulmonary hypertension and diastolic dysfunction. results: in heart failure patients either inter or intra-atrial asynchrony were far more common in comparison with normal subjects (p=0.008 and p=0.007 respectively). patients and methods: t...

This paper surveys the current state-of-the-art in wireless communication technology within vehicles, as well as between vehicles. Different concepts associated with radio frequency bands and wave propagation simulations as they apply to inter-vehicle communication are analyzed. The Medium Access Control (MAC) layer protocols used in inter-vehicle communication are addressed, as are routing pro...

To examine the genetic variation for drought stress in chamomile, eight accessions belonging to four species were evaluated under both field and greenhouse conditions using normal and late season drought stress. In the field experiment drought stress were initiated with irrigation cease at the commencement of flowering time. In greenhouse experiment, irrigation carried out at flower initiation ...

the internal structure of a molecule can be presented in terms of intra-molecular (i.e., inter atomic)and inter-molecular energies such as van der waals, bond and bending, torsion, and inversion energy.in this study, changes in molecular energies of individual asphalt components are evaluated as afunction of physical aging factors. the factors for physical aging such as temperature and pressure...
