The present investigation revealed the effect of using silica fume and copper slag as a partial replacement of cement and fine aggregate, respectively on the mechanical properties of the concrete. Due to the depletion of natural sand resource worldwide with the increment of industrial waste, simultaneously, partial replacements of fine aggregate with copper slag have been attempted. Therefore, ...

The effect of pig iron slag particles on soil physico-chemical, biological and certain soil enzyme properties was studied. Contamination of iron slag particles altered physico-chemical, biological and enzyme properties of soil. While soil pH increased slightly, electrical conductivity, carbon, potassium and phosphorus contents increased significantly in polluted soil. Contamination of soil with...

WINNING ABSTRACT: Immune characteristics distinguishing tolerant lung transplant recipients (LTR) from patients with Bronchiolitis obliterans syndrome (BOS) are largely unknown. We compared the effect of dendritic cells (DC) on T-cell activation in healthy LTR (non BOS) and in BOS patients. 30 Non BOS and 14 BOS recipients were studied. Mature dendritic cells were derived from blood monocytes a...

RATIONALE Early diagnosis of bronchiolitis obliterans syndrome (BOS) is critical in understanding pathogenesis and devising therapeutic trials. Although potential-BOS stage (BOS 0-p), encompassing early changes in FEV(1) and forced expiratory flow, midexpiratory phase (FEF(25-75%)), has been proposed, there is a paucity of data validating its utility in single-lung transplantation. OBJECTIVE ...

smelting of hammerable iron and its treatment in antiquity and Medieval produced also by-product: slag. Because of small yields of iron the process produced only small amounts of slag that did not attract attention of smelters concerning its possible use. the use of slag pieces was only accidental. a lot of slag pieces and blocks from slag pit shaft furnaces were used as a material for mound bu...

Alumina-rich iron ore is a widely existed polymetallic deposit in the nature, and it has a high comprehensive utilization value. Because the alumina and iron contents of alumina-rich iron ore vary from each other, there are many different measures and processes to recover iron and alumina from the various kinds of alumina-rich iron ore. In the blast furnace (BF) ironmaking process, the alumina ...

Bronchiolitis obliterans syndrome (BOS) is a severe complication after lung transplantation (LTX). In a retrospective cohort study 12 stable healthy recipients (non-BOS) and eight patients with BOS were enrolled after LTX and matrix metalloproteinases (MMP)-9, TIMP-1 and cell characteristics in bronchoalveolar lavage (BAL) samples (n = 145) were analysed. BALs from patients with BOS were furthe...

STUDY OBJECTIVES Lung transplantation continues to be limited by the development of chronic allograft dysfunction in the form of bronchiolitis obliterans syndrome (BOS). The effect of a transplant operation on patients with BOS has not been well-studied, but patients who undergo double-lung transplantation have better long-term survival. We hypothesized that double-lung transplantation leads to...

–The objective of present work is to use this industrial waste i.e. Slag as particulate filler material to the epoxy matrix composites by molding technique with different weight fractions ( 0%, 5%,10%,15%, 20% ) to study the mechanical behaviour of reinforced polymer composite material. The change in weight is studied for Slag under different tests like, tensile, bending and impact for obtainin...
