    The design and construction of earthquake resistant structures can counter the aspect of the earthquake hazard with effective application of engineering knowledge. Most seismic design codes today include the nonlinear response of a structure implicitly through ‘Response reduction factor’(R) by IS 1893 (Part I):2002.This factor allows a designer to use a linear elastic force-based design while accounting for non-linear behavior and deformation limits. Performance based seismic design method which is recent path of seismic assessment, both efficient and effective to avoid future earthquake losses. In this work, performance based seismic design of buildings by pushover analysis method in four different seismic zones II, III, IV and V studied. For analysis building models of G+12, G+16 and G+20 stories, plan rectangular shaped generated by a computer program SAP 2000(version 19).In this present work attempt is made to study and obtained Response Reduction Factor in different zones II, III, IV and V. Also different parameters like displacement, drift, pushover curves, performance point and plastic hinge mechanism studied

    Implementation of a Portable Learning Management System (PLMS) without Internet for Skill Development in a rural Educational Institute’s

    Skill development initiatives are critical for India's advancement since they reduce unemployment, stimulate economic growth, promote inclusion, and strengthen the country's worldwide competitiveness. By investing in skill development, India can capitalize on its demographic dividend and unleash the potential of its workforce for long-term growth and prosperity. The situation of education in rural India is frequently marked by several problems, particularly when it comes to accessing technology resources such as the internet and Learning Management Systems (LMS). Rural education infrastructure is often less developed than in urban areas, resulting in limited access to new technologies and digital resources. The Present research paper focuses on design and implement portable Learning Management System (PLMS) without internet for skill development in rural education Institutes

    Improper parking can cause several issues and problems, including Reduced Accessibility, Inconvenience for Other Drivers, Public Transportation Disruption, Environmental and Aesthetic Concerns, Public Perception, and Traffic Congestion. Addressing these issues typically calls for a combination of traffic management, public awareness campaigns, law enforcement, smart urban design, and community involvement to preserve the successful and safe usage of public spaces

    Greenhouse Parameters Monitoring and Controlling System Using Arduino and Android

    Get PDF
    Greenhouse parameter monitoring and controlling system is basically designed to monitor and control various parameters of a greenhouse for efficient growth of plants. The system has been designed using Arduino, GSM, ZigBee and Sensors. The temperature, light and soil moisture sensors are used to measure the respective parameters of the greenhouse, further these measured values will be sent to Android app via GSM. As different plants require different moisture, by analyzing the values from the app the user can control the moisture by turning on the water pump via message to GSM. The objective of this project is to provide user full access to greenhouse on a single click through Android

    Effect of High Pressure Coolant on Surface Finish In Turning Operation,

    Abstract: Present study focuses on effect of high pressure coolant on surface finish of EN8 material during turning operation. In industry common practices is to use low pressure coolant up to 10 bar. In the present experimentation, instead of low pressure, high pressure coolant of 10 bar to 70 bar is used. The experimentation is done on CNC machine during turning operation of a particular job of EN8 material. It is concluded that increase of pressure results improved surface finish to considerable level

    Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

    Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection
