The recovery of iron from the screw classifier overflow slimes by direct flotation was studied.The relative effectiveness of sodium silicates with different silica-to-soda mole ratios as depressants for silica and silicate bearing minerals was investigated.Silica-to-soda mole ratio and silicate dosage were found to have significant effect on the separation efficiency.The results show that an increase of Fe content in the concentrate is observed with concomitant reduction in SiO2 and Al2O3 levels when a particular type of sodium silicate at a proper dosage is used.The concentrate of 58.89wt% Fe,4.68wt% SiO2,and 5.28wt% Al2O3 with the weight recovery of 38.74% and the metal recovery of 41.13% can be obtained from the iron ore slimes with 54.44wt% Fe,6.72wt% SiO2,and 6.80wt% Al2O3,when Na2SiO3 with a silica-to-soda mole ratio of 2.19 is used as a depressant at a feed rate of 0.2 kg/t. 相似文献

A unit cylinder cell model with a body-fitted coordinate system is employed to analyze the hydrodynamics and heat transfer associated with steam condensation on a spray of equal sized water droplets. The droplets are assumed to be moving in the intermediate Reynolds number regime, Reg = O(100). The distance between neighboring droplet centers is allowed to be arbitrary in the plane of motion, but the droplets are assumed to be uniformly spaced in the plane perpendicular to the direction of motion. Furthermore, once a particular configuration of the droplets is set, the subsequent spacings between the droplet centers in that configuration are taken to remain constant during the entire condensation process. The formulation entails a simultaneous numerical solution of the quasi-steady elliptic partial differential equations that describe the flow field in both the dispersed and continuous phases in each cell. In part 1 of this study, the results for the velocity, surface pressure and drag are presented. In part II of this study, the results for the condensation induced velocities, surface shear stress, the Nusselt number and the Sherwood number are provided. In both parts of the study, the interactions between neighboring drops have been examined. 相似文献

Plurimonism is a new philosophy and method of science. It holds that the revolution in computer science and artificial intelligence has reached the point that all the sciences in general can now account for the complex relations of an irreducible plurality of unique observers engaged in describing the same event. Plurimonism seeks to describe the conscious and unconscious relations of the scientific observer during the act of observation of a given event while preserving the historical uniqueness and indivisible identity of each such observer. Using the framework of plurimonism, we mathematically formulate the problem of empathy. This self-reflective mathematical model entails four components of the empathic process involving two observers. They are: 1) the self; 2) the self's-other; 3) the other; and 4) the other's-self. It measures the degree of accuracy of the therapist-observer's empathy, as well as conscious and unconscious processes involved in the patient-observer's idealization and the therapist-observer's confidence in clinical psychotherapy. Ratings are obtained from both patient and therapist from four different points of view. The plural views of the patient's global assessment of functioning (GAF) are from: 1) the therapist's view (TGAF); 2) the patient's view (PGAF); 3) the therapist empathic view (TEGAF), which represents the therapist's estimate of PGAF; and 4) the patient's empathic estimate of the TGAF. The GAF scale is the standard dimensional 100-point-scale measure used in psychiatry for recording a patient's functioning. The patient's estimate of the therapist's degree of accuracy as well as the therapist's confidence in his or her empathic accuracy is also represented. Three formulae are presented that describe the degree of the therapist's empathic accuracy, the patient's over-idealization/under-idealization, and the therapist's over-confidence/under-confidence. The concept of empathy is here restricted to mean the degree to which one observer can take the point of view of another observer when both are observing the same thing. 相似文献

Micromolding technology is widely used for the fabrication of polymer microneedles for transdermal and intradermal drug delivery applications. Geometric features of microneedles in molding are solely determined by geometry of the master mold template. Fabrication of master mold template usually involves costly and cumbersome technologies due to small feature sizes typical of microneedles. In this research, a novel molding platform is designed that is fabricated using low‐cost and simple techniques with flexibility of producing large number of microneedle geometries. The proposed molding platform eliminates need for developing multiple mold templates for fabrication of various geometries of polymer microneedles. Utility of this molding platform is demonstrated in polylactic acid‐based solid thermoplastic microneedles and polyacrylic acid‐based dissolvable microneedles with various aspect ratio settings. Various microneedles fabricated at heights differing with resolution of as low as 100 µm are successfully achieved using specified settings in the molding platform. The suitability of fabricated microneedles for drug delivery applications is evaluated by in vitro and in vivo testing. 相似文献

The formulation for a unit cylinder cell model that was used to analyze the hydrodynamics and heat transfer associated with steam condensation on a spray of equal sized water droplets was presented in part I of this study. In this part II, we report the results and discussions for the condensation induced interfacial velocities, surface shear stress, Nusselt number and the Sherwood number. The heat transport in both phases and the species transport in the continuous phase have been treated as transient processes. The interactions between neighboring drops have been examined. Numerically obtained transport results have been compared with an experimental study. Results for a representative spray show that the use of correlations developed for an isolated drop to predict condensation spray behavior may be inaccurate, although isolated drop studies continue to merit investigations. 相似文献

This paper presents a study of Geography Markup Language (GML), the issues that arise from using GML for spatial applications,
including storage, parsing, querying and visualization, as well as the use of GML for mobile devices and web services. GML
is a modeling language developed by the Open Geospatial Consortium (OGC) as a medium of uniform geographic data storage and
exchange among diverse applications. Many new XML-based languages are being developed as open standards in various areas of
application. It would be beneficial to integrate such languages with GML during the developmental stages, taking full advantage
of a non-proprietary universal standard. As GML is a relatively new language still in development, data processing techniques
need to be refined further in order for GML to become a more efficient medium for geospatial applications.
