Background Phase-contrast MRI (PC-MRI) can be used to assess valvular heart diseases. It can also measure pulmonarysystemic flow ratio (Qp/Qs) and help identify intracardiac shunts. However, phase offsets in PC-MRI caused by main field inhomogeneity and eddy-current introduce baseline offset errors in flow quantification and hence Qp/Qs. This error can be corrected by surface-fitting [1] or usi...

extended abstract background and objectives sugarcane (saccharum officinarum l.) is from poaceae trible and perennial native plant of asia continent warm areas. ratio fv/fm estimates the maximum quantum yield of photosystem ii. under conditions of stress fv/fm decreased, this decreasing is due to low activity of reaction of photosynthesis centers and reducing of proteins that are responsible fo...

Quetiapine (QP) is a second-generation short-acting antipsychotic drug extensively metabolized in the liver, producing pharmacologically inactive metabolites and leading to diminished bioavailability. Therefore, this study aimed develop an intravenous QP albumin nanoparticles (NPs) system for improving activity brain targeting. QP-loaded NPs were prepared by desolvation method. The fabricated c...

Quartz powder (QP) from mining exploration has increased, and valorisation solutions are sought. QP incorporation in structural concrete is an exciting strategy for the growth sustainable development of industry, waste management environmental protection. This work addresses a Portuguese company on powder-type self-compacting architectural purposes, combining light colour quartz with white ceme...

conclusions we found that ei and qp/qs ratio are significantly and positively associated and qp/qs ratio can be easily estimated by measuring ei in secundum type asd patients. background one of the inclusion criteria for applying atrial septal defect (asd) closing procedure is an increased pulmonary-to-systemic blood flow ratio (qp/qs). eccentricity index (ei) is associated with ventricular dys...

In this paper we deal with the parallel approximabil-ity of a special class of Quadratic Programming (QP), called Smooth Positive Quadratic Programming. This subclass of QP is obtained by imposing restrictions on the coeecients of the QP instance. The Smoothness condition restricts the magnitudes of the coeecients while the positiveness requires that all the coeecients be non-negative. Interest...
