Molten iron is prepared by (1) providing iron oxide and a carbonaceous reducing agent, (2) preparing a shaped product from the carbonaceous reducing agent and the iron oxide, (3) preparing solid reduced iron from the shaped product, wherein the solid reduced iron has a metallization of at least 60%, a specific gravity of at least 1.7, and a carbon content of at least 50% of the theoretical ...

However, this conclusion was drawn only based on the experimental data, and no further experimental research on the catalytic mechanism has been carried out. Generally, a higher CO 2 pressure is beneficial to the dissolution of CO 2 in water to form carbonate (CO 3 2− ) or bicarbonate (HCO 3 − ), which could increase the carbonation degree.

tives of economic agents would produce distur-bances in observed behavior whose properties depended on their source and whether they were known to the agents (Griliches, 1957; Yair Mundlak, 1963; Griliches and Vidar Ringstad, 1970). I began working on these problems in 1962, in …

Apr 03, 2020· Combining a survey of Swiss firms with a quasi-experimental research design finds that the pandemic caused firms to reduce their 2020 investment plans by over one-eighth. Firms in regions more exposed to the virus and industries more sensitive to government-imposed restrictions cut their investments more.

Jun 01, 2015· In this study, the granulated steel slag aggregate made into spherical shape of different sizes with all fine ground steel slag was treated by accelerated carbonation process with a certain temperature, humidity and CO 2 pressure for 4 h,, . 2. Experimental study2.1. Material

In the present study, we have used nitric acid as the leaching agent so that surface and solution complexation reactions are avoided and precipitation reactions are suppressed. Steel slag, which is non-porous and contains RO phase globules embedded in calcium silicate and dicalcium ferrite matrix, was found to release the RO phase globules with ...

A topically used Chinese herbal paste, namely, CDNR, was designed to facilitate fracture healing which is usually not addressed in general hospital care. From our in vitro studies, CDNR significantly inhibited the release of nitric oxide from RAW264.7 cells by 51 to 77%. This indicated its anti-inflammatory effect. CDNR also promoted the growth of bone cells by stimulating the proliferation of ...

A test of tuyere injection of BOF slag into the LKAB Experimental Blast Furnace (hereafter called EBF) also resulted in greatly decreased Si content of hot metal[12] . The reason for injecting fluxes containing CaO and MgO is that the activity of SiO 2 in the tuyere slag is thereby decreased and followed by a decreased generation of SiO gas.

Apr 08, 2021· PARP inhibitors (PARPi) benefit only a fraction of breast cancer patients with BRCA mutations, and their efficacy is even more limited in triple-negative breast cancer (TNBC) due to clinical primary and acquired resistance. Here, we found that the efficacy of the PARPi olaparib in TNBC can be improved by combination with the CDK4/6 inhibitor (CDK4/6i) palbociclib.

Many Gram-negative bacterial pathogens require a type 3 secretion system (T3SS) to deliver effector proteins into eukaryotic cells. Contact of the tip complex of the T3SS with a target eukaryotic cell initiates secretion of the two bacterial proteins that assemble into the translocon pore in the plasma membrane. The translocon pore functions to regulate effector protein secretion and is the ...
