This paper describes the modifications and evolution of a thermal pulse combustionmodel for predicting the combustion oscillations of an aerovalved 250 kW pulse combustorincorporating a soot formation-combustion model. Validation of the model is carried out from theexperimental data of an aerovalved Helmholtz type pulse combustor, where a sinusoidal air inlet massflow coupled with pressure osci...

a 30-year-old woman presented with a palpable subcutaneous nodule in the areolar region of the left breast. sonomammographic examination revealed 2 cystic lesions showing typical “filarial dance” as vigorous twirling movement of multiple curvilinear echoes with mixed red blue color doppler signals that was non-rhythmic, nonpulsatile, and the characteristic pulse doppler trace due to irregular w...

Drug treatment of hypertension reduces systolic and diastolic blood pressure according to a well-established dose-response curve. Whether there is a parallel decrease in mean blood pressure and pulse pressure has not been investigated in the past Recent analysis of the literature and personal work indicates that, during drug treatment of hypertension, a significant decrease in systolic and dias...

Background: The end of 2019, Wuhan experienced an insurgence coronavirus within two months this prolong pandemic. Patients with Covid-19 have chance in suffering a serious damage respiratory system, which then lead to hypoxemia. harmful silent hypoxemia is that either the patients are remain untreated or they will not seek any treatment at all, though their blood oxygen levels (SpO2 levels) slo...
