CleanTX Analysis on the Smart Grid
The utility industry in the United States has an opportunity to revolutionize its electric grid system by utilizing emerging software, hardware and wireless technologies and renewable energy sources. As electricity generation in the U.S. increases by over 30% from today’s generation of 4,100 Terawatt hours per year to a production of 5,400 Terawatt hours per year by 2030, a new type of grid is necessary to ensure reliable and quality power. The projected U.S. population increase and economic growth will require a grid that can transmit and distribute significantly more power than it does today. Known as a Smart Grid, this system enables two- way transmission of electrons and information to create a demand-response system that will optimize electricity delivery to consumers. This paper outlines the issues with the current grid infrastructure, discusses the economic advantages of the Smart Grid for both consumers and utilities, and examines the emerging technologies that will enable cleaner, more efficient and cost- effective power transmission and consumption.IC2 Institut
EMR Adoption: A User Perception Study
Despite promise of significant benefits, inadequate user acceptance has frequently limited the impact of EMR implementations. Using an action research approach, our team is participating in an EMR implementation at Aravind Eye Care System (AECS), one of the largest eye hospitals in the world, to observe its current practices, measure user perceptions of EMR, plan interventions, and assess their impact. Our proximate research objective is to develop interventions based on sound conceptual foundations and empirical validation rather than in an ad hoc manner, to facilitate EMR acceptance by AECS hospital staff. The ensuing goal is to learn from the post intervention findings to develop guidelines for EMR implementations, particularly in a developing country context. In this paper we report on the first phase of this study, and these initial results show how even simple analysis of perception patterns can help to customize and shape intervention plans
CO 2 Sequestration of Vehicular Exhaust Using Synthesized Adsorbent
ABSTRACT:Activated Carbon prepared from Sugarcane Bagasse(SC) was selected as the suitable adsorbent for CO 2 sequestration and an experimental analysis was carried out to study the effectiveness of adsorption of the vehicular exhaust on the adsorbent. The adsorbent was prepared by slow pyrolysis of Sugarcane Bagasse at 600 o C. Because of the increasing level of greenhouse gases in the atmosphere due to our dependence on fossil fuels, the need to create a cost efficient,reusable material with a high CO 2 adsorption capacityhas become necessity. In this paper the FTIR analysis of the SC600 o C was carried out. The vehicular exhaust was injected into a thin film reactor after H 2 S removal. The effectiveness of adsorption was tested at an emission testing centre while removal of H 2 S was tested by simple qualitative analysis
Comparative analysis of the effect of ionospheric delay on user position accuracy using single and dual frequency GPS receivers over Indian region
57-61The ionosphere acts as a prominent source of range errors for users of Global Positioning System (GPS) satellite signals requiring accurate position determination. Various models and mathematical formulations have been devised to calculate the absolute range error caused due to ionospheric delay. The present study aims at comparing two methods for calculating delay due to ionosphere: (i) using grid based model at L1 carrier frequency with bilinear interpolation technique; and (ii) using pseudo-range measurements at both L1 and L2 carrier frequency. For analyzing the effect of ionospheric delay on the seasonal behaviour of positional accuracy, a quantitative analysis has been done for all quiet days (Ap index < 50) in 2005 using GPS data for International GNSS Service (IGS) Bangalore (IISc) receiver in January, March and June. Various corrections such as satellite clock bias, transit time, ionospheric delay corrections, etc. are applied to pseudo-ranges to calculate the user coordinates. For single frequency (L1) receivers, ionospheric delay corrections have been applied using IGS total electron content data derived from grid based ionospheric model; and for the dual frequency receivers, pseudo-range measurements at L1 and L2 carrier frequencies have been used. It has been observed that there is an improvement of 1-4 m in the standard deviation of position errors when the ionospheric delay correction is applied using pseudo-range measurements at L1 and L2 frequencies (dual frequency receiver) as compared to L1 frequency only. It has also been observed that some residual errors still remain in the estimated user position even after using dual frequency receivers
Cloning, purification, crystallization and preliminary structural studies of penicillin V acylase from Bacillus subtilis
An unannotated protein reported from B. subtilis has been expressed in E. coli and identified as possessing penicillin V acylase activity. The crystallization and preliminary crystallographic analysis of this penicillin V acylase is presented
The New World of Philanthropy: How Changing Financial Behavior, Public Policies, and COVID-19 Affect Nonprofit Fundraising and Marketing
Evolving financial behavior, an unpredictable public policy atmosphere, and an unparalleled global pandemic have collaborated to disrupt nonprofit fundraising. The COVID-19 pandemic alone exacerbated consumer demands for nonprofit services while curtailing nonprofit organizations\u27 ability to fundraise. Without fundraising, nonprofit organizations cannot achieve their mission or support their causes, leading to a precarious situation for societal well-being. Meanwhile, consumers are changing their financial behaviors, with younger generations often going cashless. At the same time, governments continue to change policies that affect nonprofit organizations. In keeping with the transformative consumer research movement, the present study provides a conceptual framework for the state of nonprofit fundraising amid the challenges associated with changes in financial behavior and public policy, coupled with the effects of the global pandemic. Marketing strategies for fundraising success are presented to aid nonprofits going forward and serve societal interests
