Development of carbon ferrochrome smelting technology using high-ash coal
This article presents the results of experimental tests using coal from the Saryadyr deposit as a reducing agent for the smelting of carbonaceous ferrochrome. Large-scale laboratory tests were carried out on the smelting of carbonaceous ferrochrome in an ore-thermal furnace with a capacity of 200 kV 路 A. X-ray diffraction analysis of the obtained alloy and slag on a diffractometer was carried out. The presence of forsterite 2MgO路SiO2 and magnesitochromite Cr2Fe0,2Mg0,8O4 in the slag was revealed, as well as the FeCr compound and the absence of silicide compounds. The optimal percentage of replacing traditional coke with coal up to 30% (by weight) has been found, which can significantly reduce the specific consumption of quartzite in the charge

Association of Common and Rare Variants with Alzheimer鈥檚 Disease in over 13,000 Diverse Individuals with Whole-Genome Sequencing from the Alzheimer鈥檚 Disease Sequencing Project
Alzheimer鈥檚 Disease (AD) is a common disorder of the elderly that is both highly heritable and genetically heterogeneous. Here, we investigated the association between AD and both common variants and aggregates of rare coding and noncoding variants in 13,371 individuals of diverse ancestry with whole genome sequence (WGS) data. Pooled-population analyses identified genetic variants in or near
APOE, BIN1
, and
LINC00320
significantly associated with AD (p < 5脳10
-8
). Population-specific analyses identified a haplotype on chromosome 14 including
PSEN1
associated with AD in Hispanics, further supported by aggregate testing of rare coding and noncoding variants in this region. Finally, we observed suggestive associations (p < 5脳10
-5
) of aggregates of rare coding rare variants in
ABCA7
among non-Hispanic Whites (p=5.4脳10
-6
), and rare noncoding variants in the promoter of
TOMM40
distinct of
APOE
in pooled-population analyses (p=7.2脳10
-8
). Complementary pooled-population and population-specific analyses offered unique insights into the genetic architecture of AD
