1. Introduction This paper focuses on the properties of Schubert cells as quasi-projective subva-rieties of a generalized ag variety. More speciically, we investigate the problem of distinguishing between diierent Schubert cells using vanishing patterns of generalized Pl ucker coordinates.

the aim of this study was to investigate the effect of three types of resistance training program on girls' physical fitness. 30 girls were divided into 3 groups: plyometric training with vascular occlusion (plo), plyometric training without vascular occlusion (pl) and power-resistance training (pr). training programs were conducted for six weeks. physical fitness tests were conducted befo...

Posttransfusion purpura typically occurs in PL negative blood recipients who have been previously immunized to the PL antigen. Following transfusion. severe thrombocytopenia develops with the formation of anti-PL . Since the patients’ platelets lack the PL antigen. one would not expect this antibody to destroy autologous platelets. In this study we show that PL antigen exists in stored blood an...

The effect of dietary safflower phospholipid (Saf-PL) and soybean phospholipid (Soy-PL) on plasma, liver, and fecal lipids in rats fed a hypercholesterolemic diet was compared with that of triglyceride mixture (controls). Triglyceride mixture (SP-Oil) of safflower oil and palm oil (8:2) contained almost comparable amounts of linoleic acid to safflower phospholipid or soybean phospholipid. Conce...

We investigated native structures and mitogenic properties of pokeweed lectin-D isoforms (PL-D1 and -D2) on human peripheral blood lymphocytes along with other isolectins (PL-A to -C). Both native PL-D isoforms appeared to behave as monomers. PL-D2 proliferated the lymphocytes like PL-C, whereas PL-D1 had no mitogenicity. PL-D1 acquired mitogenic activity after trimming of the C-terminal dipept...

Epigenetic regulatory mechanisms heritably alter patterns of gene expression without changes in DNA sequence. Epigenetic states are often correlated with developmentally imposed alterations in genomic DNA methylation and local chromatin structure. Pl-Blotched is a stable epigenetic allele of the maize anthocyanin regulatory gene, purple plant1(pl). Pl-Blotched plants display a variegated patter...

Although feedback is considered to be an important factor in perceptual learning (PL), its role is normally considered limited to facilitation, rather than direct inducement, of PL. Recent studies, however, have suggested feedback to be more actively involved in the inducement of PL. The current study demonstrates an even more significant role for feedback in PL: feedback can evoke PL of a feat...
