Optimization Model and Pollution Treatment of Sintering Ore Distribution

sintering process plays an important role in iron and steel smelting process. The subsequent production of blast furnace ironmaking is directly affected by the quality of sinter. Among them, the proportion of raw materials and the advanced degree of sintering process are the two main factors affecting the quality of sinter. Because the control parameters of sintering process are too many and the physical and chemical process is too complex, it is difficult to establish and control the model accurately. Therefore, workers have long relied on experience to set temperature and other factors to engage in production, resulting in the quality of sinter is unstable, the cost is not easy to be controlled. Moreover, the flue gas produced in the sintering process will have different effects on the environment. Through the data analysis of the ore distribution scheme and the results of the physicochemical analysis of sinter in a steel plant, two aspects of the work are completed: one is to establish the optimal model of the cost of the sintering process, and the most suitable temperature for the sintering process. The second is the analysis of harmful components produced in sintering process

The Effects on SS, TT, and UU from Higher-Dimensional Fermion Representations

Inspired by a new class of walking technicolor models recently proposed using higher-dimensional technifermions, we consider the oblique corrections from heavy non-degenerate fermions with two classes of higher-dimensional representations of the electroweak gauge group itself. One is chiral SM-like, and the other is vector-like. In both cases, we obtain explicit expressions for $S$, $T$, $U$ in terms of the fermion masses. We find that to keep the $T$ parameter ultraviolet-finite there must be a stringent constraint on the mass non-degeneracy of a heavy fermion multiplet.Comment: 4 page

Evidence that fructose 1,6-bisphosphate specifically protects the α-subunit of pyrophosphate-dependent 6-phosphofructo-1-phosphotransferase against proteolytic degradation

AbstractPyrophosphate-dependent 6-phosphofructo-1-phosphotransferase (PFP) consists of α (regulatory) and β (catalytic) subunits. The α-subunit was previously reported to be much more susceptible to tryptic digestion than the β-subunit. In this study, ligand-induced protection of PFP subunits against proteolysis by subtilisin was investigated in vitro and the data obtained demonstrated that fructose 1,6-bisphosphate (Fru-1,6-P2), while exerting negligible effect on the β-subunit, remarkably protected the α-subunit against proteolytic degradation. Western blot analysis revealed a good correlation between the Fru-1,6-P2 concentration and the degree of corresponding protection on the α-subunit against proteolysis. In contrast, none of other examined ligands including fructose 2,6-bisphosphate, fructose 6-phosphate and pyrophosphate had such protection on the α-subunit. This finding (1) indicates that the stability of the α-subunit can be selectively increased by Fru-1,6-P2, and (2) suggests that Fru-1,6-P2 is likely a special effector of the α-subunit
