To investigate the properties of phagolysosome (PL) fusion in Acanthamoeba homogenates, it was necessary to develop reliable methods for measuring in vitro PL fusion. The need to distinguish PL fusion from PL adhesion was met by the development of a quantitative electron microscope assay. Initial characterization of the fusion reaction by this method was followed by the development of a more ra...

Abs&act-A 3 x 2 factorial experiment was performed to compare the effects of procedure format (none, internal, or external) with those of comments (absent or present) on the readability of a PL/I program. The readability of six editions of the program, each having a different combination of these factors, was inferred from the accuracy with which students could answer questions about the progra...

We introduce a metric notion of Ricci curvature for PL manifolds and study its convergence properties. We also prove a fitting version of the Bonnet-Myers Theorem, for surfaces as well as for a large class of higher dimensional manifolds.

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...
