OBJECTIVES The purpose of this study was to determine the origin of the pulmonary venous systolic flow pulse using wave-intensity analysis to separate forward- and backward-going waves. BACKGROUND The mechanism of the pulmonary venous systolic flow pulse is unclear and could be a "suction effect" due to a fall in atrial pressure (backward-going wave) or a "pushing effect" due to forward-propa...

To evaluate the relationship between total organic carbon (TOC) and Rock-Eval S2 (petroleum potential) of petroleum source rocks, atotal of 180 outcrop samples from the black organic matter–rich facies of Mesozoic strata from a locality of southwest of Iran wereinvestigated using Rock-Eval VI pyrolysis and Leco Carbon Analyzer. The linear regression is applied to determine the correlationbetwee...

We consider closed topological 4-manifolds M $M$ with universal cover S 2 × ${S^2\times {S^2}}$ and Euler characteristic χ ( ) = 1 $\chi (M) 1$ . All such manifolds π ≅ Z / 4 $\pi =\pi _1(M)\cong {\mathbb {Z}/{4}}$ are homotopy equivalent. In this case, we show that there four homeomorphism types, propose a candidate for smooth example is not homeomorphic to the geometric quotient. If \cong \ma...

Empirical density plots (Fig A to J) suggest that π̂IBD for pairs of parasite samples within and across clinics loosely follow a mixture distribution over three classes: 1) near zero π̂IBD shown in green; 2) low to intermediate π̂IBD shown in shades of blue; and 3) high π̂IBD, which notably rarefies with distance, and is colored red if sufficiently dense to be visible, and otherwise outlined in bla...

this study was carried out to investigate the direct and indirect responses to selection for four-week body weight (4 week body (wk bw)) and four-week breast weight (4 week breast weight (wk brw)) and to determine the genetic contribution of reminder founders to the last generation. a total number of 351 birds were equally allocated to three lines, including two selected lines (s1 and s2 for bw...
