Innovation is a necessary requirement for companies to gain and maintain competitive advantage. This is largely due to the rapid development of technologies. In order to survive in the competitive environment, large companies should also strive for innovation in different parts of their organization. Therefore, the issue of adaptability is particularly important in introducing the innovation model. It can be assumed that inter-company collaboration is increasingly important at different stages of business development and that large corporations are willing to engage with startups. This interaction allows start-ups to overcome the problems that emerge in the early stages of business development, and on the other hand, the influx of innovation for large corporations increases the competitive advantage against their rivals, to gain more market share. The purpose of this article is to analyze the methods of collaboration between large corporations and start-ups, especially to examine the needs of innovation in the economy. This partnership can take many forms, and this article reviews the different types of partnerships between large corporations and startups that relate to business acceleration activities, co-creation, co-branding, acquisition, acqui-hiring and open innovation. Finally, by examining each of these methods of cooperation, we conclude that cooperation in any way can be beneficial to both parties and there are important points that must be considered before and during the cooperation process, so that both companies can ultimately benefit from the relationship.

In this study, oxy-combustion is numerically investigated under MILD conditions. This novel combination is ‎simulated in a laboratory-scale furnace with parallel fuel and oxidant jets and a recirculating flow. With nitrogen ‎removal from the oxidant stream, zero NOx emission for gaseous fuel systems is expected. Combustion field is ‎modelled using a well-stirred reactor and computational fluid dynamics. In the CFD modelling, RANS equations ‎are solved using RNG k-ε and EDC model is employed to model the turbulence-chemistry interaction. The effect ‎of oxidizer preheating and CO2 dilution on the combustion field as well as flue gas composition is investigated. ‎The results indicate that the flame maximum temperature does not experience a significant increase when the ‎preheat temperature rises, positively affecting the temperature distribution at the cost of CO emission which is a ‎direct consequence of higher recirculation and mixing rate. Also, a kinetic study on the chemical effect of CO2 ‎presence reveals that CO production path through CH3O radical is more strengthened compared to the main path ‎through formaldehyde when increasing the dilution level. When diluting the oxidant, methylene’s role become ‎more influential in CO formation than when pure oxygen is used, contributing to higher CO emission. CO2 defeats ‎CH4 and O2 to absorb the free H radicals, causing higher levels of CO production.‎

The concept of emotional intelligence and its effect on critical thinking and educational، professional، and health issues have come into interest. On the other hand، based on studies conducted in this regard، emotional intelligence is found to be positively associated with positive attitudes، better adaptation، improvement in relationship with others and better awareness of positive values. Accordingly، this study was performed to Comparison of academic achievement and emotional intelligence among nursing students of Isfahan University of Medical Sciences. This analytic sectional descriptive study was conducted in year 2009 in Isfahan University of Medical Sciences. Study population included all nursing students of sixth semester (both day and night students and N=100). The emotional intelligence questionnaire by Bar et al was used to determine the level of emotional intelligence among the students. Students’ academic achievement was derived based on their scores on previous final examinations recoded by nursing faculty’s chancellery of education. Data was analyzed using descriptive statistics (mean and standard deviation) as well as inferential statistics (ANOVA and t test). The mean of total academic achievement score was 15. 6±2. 92; the mean of academic achievement in theoretical lessons was 15. 2±3. 4; the mean score of academic achievement in clinical lessons was 17. 39±1. 75; and mean score of emotional intelligence was 337±35. 73 for these students. The highest score belonged to responsibility factor (25. 95±2. 84) and the lowest was associated with tension control (19. 74±3. 44). ANOVA showed that there is a statistically significant difference between mean of emotional intelligence factors and academic achievement means in the theoretical lessons (p=0. 02 and f=2. 049) as well as the total mean score of academic achievement (p=0. 015 and f=2. 153). A significant difference was observed between mean score of emotional intelligence and total mean score of academic achievement as well as mean score of academic achievement in theoretical lessons. The majority of studies in this field have approved the relationship between emotional intelligence and professional success. Therefore، recommendations have been proposed for improvement of emotional intelligence، application of findings، and further studies.
