Presents the Multicultural Counseling Inventory (MCI), a self-report instrument that measures multicultural counseling competencies. Study 1 comprised 604 psychology students, psychologists, and counselors in a midwestern state. In Study 2, respondents were a national random sample of 320 university counselors. Instrument analysis included exploratory principal-axis factor analysis with oblique rotation, assessment of factor congruence between the factor structures of the 2 samples, LISREL confirmatory factor analysis to test the relative goodness of fit of 6 competing factor models of the MCI, and tests of internal consistency reliabilities. Results indicate that the MCI has 4 factors: Multicultural Counseling Skills, Multicultural Awareness, Multicultural Counseling Relationship, and Multicultural Counseling Knowledge. A higher order, more general multicultural counseling factor is also discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Diverse novel nanomaterials are being developed for a wide range of applications nowadays. Atomic force microscopy (AFM) assumes specific importance for the measurement of size and other related properties for such nanomaterials. The different aspects related to AFM modes of operation, nanopositioning, sensing systems as well as calibration for reliable characterization in order to meet the nanometrology requirements are discussed. The future targets in this context, set by nanometrology institutes, are also highlighted. 相似文献

Carbon onions are found along with carbon nanotubes and other carbon nanoparticles in the cathodic deposit in the arc-vaporization
of graphite. Atomic force microscopy has been used to characterize these particles on the basis of their sizes and shapes.
Onion-like particles have three-dimensional, near spherical structure and are distinct from two-dimensional graphitic particles.
The spherical shape and height to diameter ratios obtained using atomic force microscope, afford a distinction between onion-like
structures and other carbon nanoparticles. 相似文献

In the light of the finding that carbon nanotubes get functionalized on reaction with acid and other oxidizing agents, the structures and shapes of nanotube derivatives resulting from possible reaction between functionalized nanotubes, are obtained by an energy minimization procedure and the structures, so obtained, are compared with the observed microscopic images. The shapes of fullerene -like and nanotupe - like structures containing seven - membered rings, in addition to six and five - membered rings, are depicted along with the structures of bent nanotubes containing similar ring systems. Diamond - graphite hybrid structures which constitute an important class of carbon materials are also investigated. 相似文献

Sodium N-dodecanoyl sarcosinate (SDDS), a novel amino-acid based surfactant, has immense biological and industrial importance. Although
it is being used in a number of cosmetic formulations, systematic analysis of the bulk and interfacial properties of the surfactant
is scarce in the literature. In this study, effects of salt, temperature, and pH on the self-association and related properties
of SDDS have been examined in detail using methods such as tensiometry, conductometry, fluorimetry, pH-metry, spectrophotometry,
calorimetry, and circular dichroism. The nature of amphiphilic packing and the aggregation numbers of the assemblies have
been deciphered. Properties of the acid form of the surfactant have also been explored. The results have been conceptually
rationalized and systematically presented together with associated energetics of the interfacial adsorption and self-aggregation
of the surfactant in the bulk.

The present report studies on the flow pattern transitions during vertical air water downflow through millichannels (0.83 ≤ Eötvös no. ≤ 20.63). Four basic flow patterns namely falling film flow, slug flow, bubbly flow, and annular flow are observed in the range of experimental conditions studied and their range of existence has been noted to vary with tube diameter and phase velocities. Based on experimental observations, phenomenological models are proposed to predict the transition boundaries between adjacent patterns. These have been validated with experimental flow pattern maps from the present experiments. Thus the study formalizes procedure for developing a generalized flow pattern map for gas‐liquid downflow in narrow tubes. © 2016 American Institute of Chemical Engineers AIChE J, 63: 792–800, 2017 相似文献

Hydrogen can be stored in containers or in materials (in molecular or atomic forms). The atomic form can further exist as multiple phases. Molecular hydrogen can be adsorbed on the surface or can be present inside the material. By invoking multiple modes of hydrogen storage, we establish a paradigm shift in the philosophy of hydrogen storage. Using a novel strategy of storage of molecular hydrogen in metal (Pd) nanocontainers, we observe that 18% hydrogen is in molecular form. Interestingly, this is achieved at 25 °C and 1 atm pressure; which is in contrast to storage in MOFs and carbonaceous materials like nanotubes. Enhancement in storage capacity as compared to Pd nanocrystals of the same mass is observed (36% increase at 1 atm & 25 °C), along with fast kinetics (0.5 wt% hydrogen absorption in 5 s). A new mechanism for hydrogen storage involving the dual catalytic role of Pd is established. 相似文献

The present work reports a computational fluid dynamic analysis of core annular flow through return bends. Core annular flow of lubricating oil and water has been simulated using FLUENT 6.3.26. A satisfactory trend matching is observed between numerically obtained phase distribution and experiments. A comprehensive study has been made to generate the profiles of velocity, pressure, and volume fraction over a wide range of oil and water velocities. It has been observed that the oil core may foul the bend wall under certain operating conditions. Through computational simulations the operating zone safe from the risk of fouling has also been identified. 相似文献
