A linear superposition method was used for modeling the time history of the production blast vibrations and optimizing the blast sequence to reduce vibration levels in Sar-Cheshmeh copper mine, Kerman, Iran. A single-hole blast for modeling and two double-hole blasts with time delays of 25 and 65 ms between two holes for modeling validation were carried out. The generated vibrations were measur...

OBJECTIVES To characterize granulocyte colony-stimulating factor receptor (CD114) expression in normal (n = 20), myelodysplastic (n = 34), and chronic myelogenous leukemia (CML; n = 5) bone marrow by flow cytometry. METHODS Clinical bone marrow samples were analyzed using CD33/CD114/CD34/CD117/CD45. CD114 density (mean fluorescence intensity) and cellular distribution were evaluated on early ...

An analytical relation between burden velocity and ratio of to blasthole diameter is developed in this paper. This found be consistent with the measured velocities all 37 full-scale blasts from published articles. These include single-hole blasts, multi-hole simultaneously-initiated various borehole diameters such as 64 mm, 76 92 115 142 mm 310 mm. All boreholes were fully charged. The agreemen...

Human thymus cells and blasts from some patients with acute lymphoblastic leukemia (ALL) express similar cell surface properties. This suggests that this type of ALL originates in the thymus or alternatively that these properties of ALL blasts reflect changes occurring during blastogenesis. To test these possibilities, we determined whether mitogen-thymus antigens found on blasts from E+ALL an...

Caryotypic analysis of the cells dividing in mouse parent-hybrid MLC showed an F1 hybrid cell proliferation, which varied depending upon the source of lymphoid cells used: strong in spleen MLC (sometimes equal to that of the parental cells), less marked in lymph node cell MLC, and most often absent in MLC between cortisone-resistant (CR) thymocytes. MLC between parental spleen cells and F1 CR t...
