A purified polyclonal antiserum directed against the isolated main 80 kD IROMP (iron-regulated outer-membrane protein) from Pseudomonas aeruginosa PAO1 detected only the 80 kD polypeptide of outer-membrane proteins from PAO1 cells grown in iron deficiency in Western blots. It was also shown to inhibit the uptake of 59Fe pyoverdin by PAO1 cells as well as its binding to purified outer membranes. Immunofluorescence experiments with intact PAO1 cells confirmed that the receptor is present only at the surface of cells grown under conditions of iron deficiency. All these data allow us to conclude that the 80 kD main IROMP of P. aeruginosa is indeed the receptor for the siderophore ferripyoverdin.

The aim of the article is to analyze the influence of corporate social responsibility (CSR) initiatives by firm on firm performance and firm risk. Moreover, the mediating role of firm reputation in CSR/performance and CSR/risk relationship is also examined. Data were collected from European and Asian firms listed on Fortune's Most Admired Countries for the period 2014-2018. Using logit regression model and OLS regressions, we find that CSR has a significant positive influence on firm reputation and firm performance whereas on firm risk it is negative. Based on our results, we also confirm that firm reputation does mediate the relationship between CSR-firm performance and CSR-firm risk. This study adds to CSR related literature by providing more reliable and objective evidence on the role of firm reputation in CSR engagement and also provides direction for future studies in this context.

Highlights Drawbacks of chemical fertilizers have attracted the attention of farmers toward biofertilizers. Nitrogen fixer Azotobacter SR-4 and phosphorus solubilizer Asphergillus Niger were produced and observed to be efficient biofertilzers. A significant increase in yield parameters were observed when these biofertilizers were evaluated on Bottle gourd and okra. In conclusion, biofertilizers or microbial inoculants could be used as an alternate source, which are both cost-effective as well as eco-friendly.

Abstract-Simulations that require massive amounts of computing power and generate tens of terabytes of data are now part of the daily lives of scientists. Analyzing and visualizing the results of these simulations as they are computed can lead not only to early insights but also to useful knowledge that can be provided as feedback to the simulation, avoiding unnecessary use of computing power. Our work is aimed at making advanced visualization tools available to scientists in a user-friendly, web-based environment where they can be accessed anytime from anywhere.In the context of turbulent combustion for example, visualization is used to understand the coupling between turbulence and the turbulent mixing of scalars. Although isosurface generation is a useful technique in this scenario, computing and rendering isosurfaces one at a time is expensive and not particularly well-suited for such a webbased framework. In this paper we propose the use of a summary structure, called contour tree, that captures the topological structure of a scalar field and guides the user in identifying useful isosurfaces. We have also designed an interface which has been integrated with a web-based simulation monitoring system, that allows users to interact with and explore multiple isosurfaces.

Despite the pivotal role of risk management very limited research is carry out on the issue of firm’s risk management capability and value creation. This study aims to analyze the impact of firms risk management capabilities on firm performance and cost. Using panel data technique a sample of 301 non financial firms was analyzed for the time period on five years starting from 2011 to 2015. We assert that effective risk capabilities have positive impact on all stakeholders. The effective risk management capabilities guarantee more resilience to exogenous and endogenous risks. Our findings will have a significant impact on existing literature, by extending the existing knowledge of firm’s risk management capabilities into the domain of diverse stakeholders and resources adjustment.
