In the context of resource constraints, how different dimensions entrepreneurial alertness affect opportunity recognition new ventures is an important issue worth studying. From cognition theory and bricolage perspectives, we systematically investigate intrinsic relationships among alertness, bricolage, passion, recognition. Further, it explored mechanism role in exploring This study applied stepwise regression analyses Bootstrap method to test hypotheses on a sample 295 questionnaires...
Two observation techniques of internal microstructure, including hole and second particle, micron scale powders have been established applied to frangible tough powders. One is that were embedded in epoxy resin, sectioned by an ultramicrotome, then observed using the transmission electron microscopy (TEM) turn; another fracture scanning (SEM).
ABSTRACT Outsourcing strategy plays an essential role in manufacturing production. Compared to traditional industries, brand spillover behavior from contract manufacturers is more prominent the fashion industry's outsourcing practices. Therefore, we have developed a model for original (OBM) choose under influence of various factors: OBM can outsource production competing manufacturer (CM), non‐competing (NCM), or produce internally. If CM only contractor OBM, it will enhance its power...
The shape of inorganic powder particles, prepared by spray-drying process, is close to sphere, and the dry conditions have greater effect on sphericity. particle normally described words or shown micrographs — these are qualitative imprecise. In order characterize quantitatively, three factors, i.e. aspect ratio (M), roundness (R) concavity (C), proposed describe powders in different aspects. An image process method, that “holes” were filled then clusters separated, was developed applied...
This study dealt with the processing, microstructure and wear behavior of vanadium carbide reinforced iron matrix composite. Powder technology combined in situ synthesis was used to successfully fabricate The composite characterized by X-ray diffraction, scanning electron microscope transmission microscope. microstructural reveals that round VC particles are distributed uniformly matrix, interface between is clean, no precipitates found. Dry-sliding VC-Fe tested using MM-200 testing machine....
(Ti,W)C particles reinforced Fe-based surface composite coatings were fabricated by in-situ synthesis and powder metallurgy route. The microstructure, interface wear properties investigated X-ray diffraction, scanning electron microscopy dry sliding test. results show that carbides form via in situ reaction between titanium, ferrotungsten graphite. morphology of is mainly rectangular form. iron matrix found to be free from cracks deleterious phases. coating possesses higher resistance than...
Determination of particle size and shape factors the corundum powders by SEM image analysis has been reported in our preceding work. However, effect sample preparation processing not investigated. In order to obtain appropriate images, samples was well-dispersed vibrating particles manually up down, then thicker Pt coating well sputter coated on surface samples; compared with magnifications 100 32, magnification 50 more reasonable; for distinguishing from background properly, gray threshold...
Nano-TiO2 coating film is one of the efficient photocatalysts. The particle size distribution TiO2 has important influence on photocatalytic activity. A new method to determine nano-film coated ceramic was developed, by which images acquired Atom force microscope (AFM) were processed, and particles contacted with others separated detected. distributions two nano-films determined.
