In order to improve the efficiency of desulfurization process utilizing mechanical stirring method, effect flux dispersion on hot metal reaction was investigated in 1/8-scale water model and 70 kg-scale experiments.Flux behavior is divided into three stages, i.e., "non-dispersion," "transition," "complete dispersion." The rate increases remarkably from "non-dispersion" dispersion" stage, corresponding change condition particle dispersion.The relationship between impeller position vortex...

We evaluated whether the inclusion of elephant cognition in an education program resulted changes attitudes towards elephants and conservation effect rurality, gender, age on attitudinal change.

Abstract The number of mature job seekers actively pursuing employment is increasing, and it critical to recognize the variety needs desires they want from employment. We hypothesized that would be grouped into meaningful clusters based on their for work these groups differ regarding features were looking in a new job. Using survey data sample 173 over age forty, we identified three clusters: Those who primarily monetary family reasons (which labeled satisficers ), those seek personal...

Hot metal desulfurization behavior with dolomite flux was examined in heat treatment tests of pellets and small-scale commercial-scale hot by mechanical stirring. In the pellets, Mg gas generation ratio at 1673 K increased as CaO/MgO increased. The reached 90% dolomite, which 1.4 times higher than that CaO + MgO same CaO/MgO. With calcined Al ash, efficiency for 20–30%, around double results CaO. slag, sulfur concentrated not Mg, but Ca were found an EPMA analysis detected CaS X-ray...

The focal article by Costanza and Finkelstein (2015) shed a light on the current status of generational research at work that often treats generation as an age grouping variable. Although authors primarily focused applicability findings to workforce, I believe benefits studying understanding generations should not be limited this purpose. goal commentary is twofold. First, would like revisit concept purposes work. Second, given problems with presented Finkelstein, propose potential actions...

The peroxidation of molten steel is a problem that occurred in combined blowing converter with inert gas bottom blowing. It was caused by the relatively weak stirring power blown compared oxygen gas. Although several methods for optimizing conditions have been developed an attempt to resolve this problem, effect equipment such as shape on metallurgical characteristics has not investigated sufficiently. In study, H/D (ratio bath depth H diameter D) reaction rate between slag and metal furnace...

In order to develop an environment-friendly steelmaking process, a slag recycling process for hot metal desulfurization by mechanical stirring was designed. The developed with 70 kg-scale experiments and actual plant tests. recycled has 70% ability compared that of virgin flux (CaO-5%CaF2). lower efficiency the caused SiO2 contamination carried over from previous process. There is no particular size requirement slag, as effect on small. ratio CaO in total should be less than 60% prevent...

This study explored Kentucky employers' preparedness for the aging workforce using focus groups and a survey. Although employers perceived many benefits of older workers, five key challenges an emerged: institutional knowledge loss, workers' dependent care commitments, health safety problems, generation gaps, lack technical skills. The results also suggested potential solutions organizational practices to address each these challenges. These include succession planning, meaningful work,...

Several studies have examined the reduction behavior of manganese ore at high temperature with aim reducing cost in steelmaking process. However, transformation compounds temperatures had not yet been clarified. Therefore, this paper, effects and oxygen partial pressure, as well chemical composition, on melting were investigated by using X-ray diffraction (XRD) thermogravimetry-differential thermal analysis (TG-DTA) order to obtain fundamental information pre-reduction process ore. The main...

The two studies presented describe the revision process that led to development of Awareness Privilege and Oppression Scale–2 (APOS-2) efforts evaluate new measure’s reliability construct validity. In Study 1, a 26-item measure was developed from data gathered sample 484 undergraduate students. An exploratory factor analysis suggested four-factor solution made up awareness racism, sexism, heterosexism, classism appropriate. 2, confirmatory proposed hierarchical best available fit using...
