The mechanical behavior of cemented gangue backfill materials(CGBMs)is closely related to particle size distribution(PSD)of aggregates and properties of cementitious ***,the true triaxial compression tests,CT scanning,SEM,and EDS tests were conducted on cemented gangue backfill samples(CGBSs)with various carbon nanotube concentrations(P_(CNT))that satisfied fractal theory for the PSD of *** mechanical properties,energy dissipations,and failure mechanisms of the CGBSs under true triaxial compression were systematically *** results indicate that appropriate carbon nanotubes(CNTs)effectively enhance the mechanical properties and energy dissipations of CGBSs through micropore filling and microcrack bridging,and the optimal effect appears at P_(CNT)of 0.08wt%.Taking PSD fractal dimension(D)of 2.500 as an example,compared to that of CGBS without CNT,the peak strength(σ_(p)),axial peak strain(ε_(1,p)),elastic strain energy(Ue),and dissipated energy(U_(d))increased by 12.76%,29.60%,19.05%,and90.39%,***,excessive CNTs can reduce the mechanical properties of CGBSs due to CNT agglomeration,manifesting a decrease inρ_(p),ε_(1,p),and the volumetric strain increment(Δε_(v))when P_(CNT)increases from 0.08wt%to 0.12wt%.Moreover,the addition of CNTs improved the integrity of CGBS after macroscopic failure,and crack extension in CGBSs appeared in two modes:detour and pass through the ***σ_(p)and U_(d)firstly increase and then decrease with increasing D,and porosity shows the opposite ***ε_(1,p)andΔε_(v)are negatively correlated with D,and CGBS with D=2.150 has the maximum deformation parameters(ε_(1,p)=0.05079,Δε_(v)=0.01990)due to the frictional slip effect caused by coarse *** increasing D,the failure modes of CGBSs are sequentially manifested as oblique shear failure,"Y-shaped"shear failure,and conjugate shear failure.

The t(8;21) translocation is one of the most frequent chromosome abnormalities in acute myeloid leukemia. This translocation creates a fusion between the acute myelogenous leukemia 1 (AML1, a transcription factor) gene on chromosome 21 and the eight-twenty-one (ETO, a zinc finger nuclear protein) gene on chromosome 8, leading to the repression of certain AML1 target genes. We cloned NHR3 domain coding fragment into vector pGEX-6p-1 using PCR and obtained recombinant plasmid pGEX-6p-1-NHR3, which can be induced to stably overexpress fusion protein in E. coli. Through the purification on GST affinity chromatography column and PreScission protease cleavage, a large amount of NHR3 protein with high purity was obtained. In order to avoid possible interference of some strong negative charged molecules, NHR3 protein was further purified by Mono Q anion exchange chromatography. The NHR3 crystals were grown with hanging drop/vapor diffusion method and the first crystals appeared after four weeks at 18 °C in 0.2 M Tris-sodium citrate dihydrate, 0.1 M sodium cacodylate, pH 6.5, and 30% iso-propanol (V/V). ESI mass spectrum showed that the molecular weight of this domain was in agreement with its primary structure sequence prediction, and circular dichroism spectral data (190–250 nm) showed that NHR3 had a well-defined secondary structure of 25.9% α-helix, 23.2% random coil and 50.9% turn, which was consistent with GOV4 software prediction.
