Abstract The effects of fly ash, Air Cooled Blast Furnace Slag (ACBFS), and silica fume on cement compressive strength are examined. concrete is studied by the addition air-cooled blast furnace slag fume. effect ACBFS, was investigated. content reduced 25%, 22.50%, 20%, 17.50%, respectively; ash used to replace 40%, 60% coarse aggregate; partially replaced 2.5%, 5%, 7.50% content. Contrarily, l...

We have used new parallax measurements, obtained by the Hipparcos satellite, of fifteen nearby, metal-poor stars to re-define the subdwarf mainsequence. All of these stars have parallaxes determined to an accuracy of at least 12 %. Comparing these measurements against previous ground-based data for nine stars reveals a systematic offset of 5 %, in the sense that the Hipparcos parallaxes are sma...

BACKGROUND The presence of high level DNA microsatellite instability (MSI-H) in colorectal cancer is associated with an improved prognosis, as is the presence of tumour infiltrating lymphocytes (TILs). It is not clear if TILs contribute directly to the survival advantage associated with MSI-H cancers through activation of an antitumour immune response. AIMS To correlate TIL and apoptosis rate...

BACKGROUND Autologous osteochondral transplantation surgery requires an impact force on the graft that may cause chondrocyte death and matrix degradation. This study attempted to determine the degree to which this occurs in a rabbit model shortly after the procedure. HYPOTHESIS Impaction of a press-fit autologous osteochondral graft in vivo results in chondrocyte necrosis, apoptosis, and matr...

This experiment aims to examine the strength characteristics of structural light weight concrete generated by substituting aggregates like Cinder (class-F) and ECA for coarse aggregate in M30 grade concrete. Lightweight is created from cinder ECA, with cement substituted at 40%, 50%, 60%, 100%. The mix design project 1:1.24:0.63. Using aforementioned percentage, we cast 15 brick specimens measu...
