The current study aims to examine the effect of Hofstede's dimensions of culture on the intention of sharing knowledge in higher education institutions (HEIs) in Jordan. In the literature, researchers have given limited attention to such an effect. Therefore, by adopting Hofstede's framework, the current study attempts to investigate how Jordan's cultural context impacts on the intentions to share knowledge in HEIs. This study applied quantitative research methods to investigate the effect of Hofstede's cultural dimensions on knowledge-sharing intentions. In total, 307 questionnaires were collected from employees in Jordanian universities and, then, tested using descriptive and regression analytical methods. The study results show that culture dimensions influence knowledge-sharing intention and that each dimension plays a different role in enhancing this knowledge-sharing intention. More specifically, it was found that long-term orientation, collectivism and high uncertainty avoidance had a positive effect on knowledge-sharing intention, while cultural masculinity and power distance had no negative effect. Based on these results, the study makes several recommendations, the most important of which is the promotion of cultural values that encourage intention to share knowledge. Also, more qualitative research is needed to explore in depth the effective means that encourage intentions to share different types of knowledge.

The hazardous enterprise has been increasing its relative importance day by day in the economy of our country and the world. However, it's mostly true to have been relatively neglected in the field of technical strategy. This is to provide for methodological frame about the research in this field in the future by researching on what kind of technical and marketing strategies make what kind of effect on the result of hazardous enterprise together with the strategy for success by meeting the necessity of this research. Therefore, the individual variable within this research was divided into three parts like technical strategy, marketing strategy and industrial environment. It used the type division of venture-company(High-tech type, Superior enterprise type, Boutique type, General enterprise type) as a controllable variable and the result of hazardous enterprise as a subordinate variable. The result of this research is that the technical strategy of hazardous enterprise has lots of possibilities to raise the financial result if it raises technical reform and supplementary character and technical integration level in case that newly-established hazardous enterprise with relatively lower capital power than big enterprise pursues technical strategy.

This study analyzed the effects of ICT technical characteristics of agricultural industry on smart farm entrepreneurial intention by using smart farm effort expectation and smart farm acceptance intention as mediators for smart farm pre-founders. Sub-variables of the technical characteristics of agricultural industry ICT were classified into availability, economics, data convergence and scalability. 349 questionnaires collected from pre-founders living in the country were used for empirical analysis. SPSS v22.0 and Process macro v3.4 were used to analyze the data based on serial multiple mediation model. First, economics and scalability had a positive (+) effect on start-up intention. Second, availability, economics and scalability had a significant effect on effort expectation. Third, effort expectation had a significant positive effect on acceptance intention. Fourth, acceptance intention had a significant positive effect on start-up intention. Fifth, the indirect effects of economics on start-up intention were all significant through effort expectation, through acceptance intention and through both effort expectation and acceptance intention. Sixth, the indirect effect of data convergence on start-up intention was significant through acceptance intention. Seventh, the indirect effect of scalability on start-up intention was significant through effort expectation and through both effort expectation and acceptance intention. As a follow-up study, it is necessary to study for the mediating variables other than mediators introduced in the study or the moderated mediation analysis through the conditional process model in which the moderating variable is introduced.

Purpose: This study was to assess clinically the success rates and technical complications of cement-retained implant-supported single crowns and splinted crowns with zirconia frameworks. Materials and methods: 75 (single crowns: 51, splinted crowns: 24) cement-retained implant-supported single crowns and splinted crowns with zirconia frameworks which were restored in 67 patients were investigated for the evaluation of the success rates and technical complications. All restorations were cemented with temporary cement. Age, gender, restoration position, opposing teeth, restoration type were assessed as possible factors affecting technical complications. Results: During the mean observation period of 22.2 months, cumulative success rates of all restorations were 66.9 (73.2 - 60.6)%. Retention loss was found in 16 restorations (single crowns: 14, splinted crowns: 2), abutment screw loosening and veneer porcelain fracture were found in each 2 single crowns, respectively. According to a Kaplan-Meier survival analysis of single crowns and splinted crowns, the cumulative success rates were 58.9 (66.6 - 51.2)%, 87.5 (96.1 - 78.9)%, respectively. There was a statistically significant difference. The other possible factors did not have a significant effect on the technical complications. Conclusion: Retention loss was the most frequent technical complication. Abutment screw loosening and veneer porcelain fracture were found rarely in single crowns only. Age, gender, restoration position, and antagonist did not have significant effect on the technical complications. Splinted crowns had a higher success rate than single crowns.

The magnetic domain-refining techniques such as ball scratching, laser irradiation and plasma have been developed to reduce the domain wall spacing and thus iron losses in Fe-3%Si grain-oriented silicon steels. In view point of magnetic properties, it was supposed that the locally residual stresses change the magnetoelastic energy of the material and thus the spacing between $180^{\circ}$ domain walls decreases in order to reduce the magnetostatic energy. The effect of laser irradiation on iron loss and magnetostriction reduction for Fe-3%Si grain-oriented steel were investigated. Since the local tensile stresses were induced at the surface of Fe-3%Si steel by the laser irradiation, the minimum iron loss caused by reducing eddy current loss was obtained in spiete of the decrease of permeability by hindering eddy current loss was obtained in spite of the decrease of permeability by hindering the domain wall movement around the induced stress field. Furthermore, the laser treated 3%Si steel has lower magnetostriction as compared to non laser-treated steel and is less sensitive to applying pre-stresses due to the volume reduction of $90^{\circ}$ domain in materials.

Research work on removal of fluoride from water, referred to as water defluoridation, has resulted into the development of a number of technologies over the years but they suffer from either cost or efficiency drawbacks. In this work, enhancement effects of phosphate and silicate on defluoridation of water by low-cost Plaster of Paris (calcined gypsum) were studied. To our knowledge, the influence of silicate on defluoridation was not reported. It was claimed, that the presence of some ions in the treated water samples, was decreasing the fluoride removal since these ions compete the fluoride ions on occupying the available adsorption sites, however, phosphate and silicate ions, from its sodium slats, have enhanced the fluoride % removal, hence, precipitation of calcium-fluoro compounds of these ions can be suggested. Percentage removal of $F^-$ by neat Plaster is 48%, the electrical conductance (EC) curve shows the typical curve of Plaster setting which begins at 20 min and finished at 30 min. The addition of phosphate and silicate ions enhances the removal of fluoride to high extent > 90%. Thermodynamics parameters showed spontaneous fluoride removal by neat Plaster and Plaster-silicate system. The percentage removal with time showed second-order reaction kinetics.
