The data of the steady rising height of capillary water were obtained, and the regression equation of coarse grained soil on steady height and physical indexes (effective grain dl0 and porosity n) was found. Compared with Hazen's and other expressions that could estimate the steady height of capillary water of coarse grained soil, the proposed method is satisfactory and the defects of the latter were pointed out.展开更多

The factors affecting quality in the construction industry should be assessed. This paper aims to introduce a new model to assess these factors. The model is namely Fuzzy Assessment Model for Quality (FAMQ). Fuzzy set theory provides a useful way to deal with ill-defined and complex problems in a decision-making environment that incorporates vagueness. The proposed model employs the combined effect of both; the factors probability of occurrence and their impacts on the quality of construction. Twenty five logical rules for each factor were implemented in the model. The model was evaluated using data that collected from the infrastructure projects in Egypt. It was applied to many factors that affect the quality of this kind of projects as a case study. The results of the study proved that the proposed model can be used successfully in the assessment of factors affecting quality in the construction industry. In addition, the results provided a platform of useful assessment reference to those infrastructure's finns, who plan to establish their businesses in Egypt.展开更多

However, existing studies mainly focus on a single or several factors and the deviation generated by the factors' effects on each other has been neglected. We aimed to study the comprehensive influences of firm-level factors on Chinese pharmaceutical firms that chose the DPI mode. Student's t tests and Chi Square tests were used to explore the differences between firms with or without DPI modes. Then, logistic regression analysis was used to explore the comprehensive impacts of these 16 variables. Through empirical research, we found the factors influencing the DPI mode of Chinese pharmaceutical enterprises and the firm-level factors that influenced DPI mode selection. This study showed that the capacity of enterprise's innovation and knowledge absorption were related to the mode selection. Moreover, the education of the top management team significantly contributed to the DPI mode selection of pharmaceutical firms. This study also provided theoretical and empirical evidence for pharmaceutical enterprises when choosing their DPI mode. The internationalization of Chinese pharmaceutical firms remained at the early stage. However, the internationalization of drug products from China would affect the international pharmaceutical supply in the long term.展开更多
