The structure of composite materials is be usually described as a compound of two structural components called matrix and reinforcement, respectively. A classic, commonly known example is polyester resin reinforced with glass fibres. Composite materials obtained through casting techniques are frequently characterised by irregular distribution and content of reinforcement in the casting volume a...

This study examines the constructs of entrepreneurial orientation (EO) versus small business orientation (SBO), their impact on small business performance, and whether these effects are moderated by longevity. A sample of 267 small business owners from 11 small–medium downtowns was used in structural equation modeling (SEM) testing of the measurement, structural and moderation hypotheses. The m...

in iran’s system of tripartite collective bargaining, does the wage-policy maker consistently react optimally to the best move made by the exchange rate-policy maker (nash-rule) or only to the state of economy (non-nash rule)?. this paper not only investigates the nature of the political game (nash rule against non-nash rule) but also estimates some structural parameters by using 2sls method an...

In this study we have demonstrated the variations of carbohydrates and phenolic compounds present in the leaves and stems of ‘Kinnow’ mandarin (Citrus reticulata Blanco) trees in alternate bearing cycle and the possible involvement of these compounds to flower bud formation process. The amounts of these compounds were determined in the leaves and stems of “on” and “off” trees  monthly  from Nov...

background: with regard to the high prevalence of schizophrenia, research on brain structural changes in this disease has been one of the interesting issues among the medical scientists. in this research, brain mri findings of schizophrenic patients have been compared with non-schizophrenic ones. methods: this study was an analytic-comparative one in which two groups of schizophrenic and non-sc...

Perovskite-type oxides of LaFe(1+x)O(3+δ) (x = 0.0, 0.2, 0.5 and 0.7) were synthesized by citrate sol–gel methodto ensure the formation of nanosized perovskites. The physicochemical properties of these LaFe(1+x)O(3+δ)materials were characterized by thermal gravimetric/differential analyses, Fourier transform infraredspectroscopy, X-ray powder diffraction, scanning electron and...
