Conceptual design of Blended Wing Body for Future Air Transportation

Blended wing body is a fixed wing aircraft which are smoothly blended together with no clear dividing line and no distinct wings also be given a wide Aerofoil shaped body. The future transportation is of aircrafts will incline towards the aerodynamically efficient and capable of carrying large number of passengers over long range and environmental benefits is the main paradigm in the design of aircraft BWB has a high lift to drag ratio which increases the CL max and velocity of the airplane with high load factor and high economy compared with traditional aircraft. Evacuation pressure or the cabin pressurization is the major issues in most of the designs with the minimum aerodynamic lift coefficient and drag coefficient. On the other side of the trend is towards the increasing cruise speed. High speed flow is connected with overcoming of intensive drag rise accruing due to existence of intensive shock, closing local area of supersonic flow. Increase of flight Mach number is possible only by using flow control methods and through affecting the shock increases of aspect ratio leads to increase of lift coefficient corresponding to maximal lift to drag. High bypass ratio engines have smaller fuel consumption and lower noise level but have negative effect on flow around airframe including take-off and landing phases. The necessity of solving problem of intensive aerodynamic heating of surface element of flight vehicles and by ensuring of their stability and controllability and also by need of implementing of high-volume tanks for hydrogen fuel and super high bypass ratio engines

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

ABSTRACT: Recommendation algorithms are best known for their use on e-commerce Web sites, where they use input about a customer&apos;s interests to generate a list of recommended items. Many applications use only the items that customers purchase and explicitly rate to represent their interests, but they can also use other attributes, including items viewed, demographic data, subject interests, and favourite artists. Collaborative filtering is one of the most important technologies in electronic commerce. With the development of recommender systems, the magnitudes of users and items grow rapidly, resulted in the extreme sparsity of user rating data set. Traditional similarity measure methods work poor in this situation, make the quality of recommendation system decreased dramatically. Poor quality is one major challenge in collaborative filtering recommender systems. Sparsity of users&apos; ratings is the major reason causing the poor quality. To address these issues we have explored item-based collaborative filtering techniques. Item based techniques first analyze the user-item matrix to identify relationships between different items, and then use these relationships to indirectly compute recommendations for users. This approach predicts item ratings that users have not rated, and then uses Pearson correlation similarity measurement to find the target items&apos; neighbors, lastly produces the recommendations. The experiments are made on a common data set using different recommender algorithms. The results show that the proposed approach can improve the accuracy of the collaborative filtering recommender system

The million tonnes quantity of paper mill sludge produced in the world. The main recycling and disposal routes for paper sludge are land-spreading as agricultural fertilizer, producing paper sludge ash, or disposal to landfill, Hypo sludge is investigated for its use as a partial replacement for cement in Hypo Sludge for strength at 7 &amp;28 days as partial replacement with the cement in the cement mortar 1:3. So it can be used in non-structural elements in the low range compressive strength where strength is not required and low cost temporary structure is prepared

Journal of International Academic Research for Multidisciplinary Editorial Board COLONIAL AND 21 ST CENTURY COLLEGES AND UNIVERSITIES PRESIDENTS: EFFECTS ON CURRENT ADMINISTRATION TRENDS

ABSTRACT The purpose of this paper presidents in both public and private colleges and universities are now more accountable to stakeholders, government and the board of trustees than they were in the colonial era. This paper examined the role of colleges and universities presidents in the politically complex context of the colonial periods and the modern era of higher education. Furthermore, it identified traces of historical perceptions that may remain in today&apos;s educational settings. It was found that several legislative higher education acts helped increase student enrolment and the responsibility of higher education institutions administrators expanded. Administrative bureaucracies began to rise in the modern era and the universities and colleges became much more like a corporate business with wellstructured administrations. As administrative hierarchies and bureaucratic management developed, trustees became corporate directors responsible for institution maintenance and administrators became business managers. Modern era presidents&apos; salaries skyrocketed in the U.S. It was concluded that the modern president&apos;s job has evolved from a cleric to a pure scholar position whose responsibilities span the vast array of functions represented in today&apos;s contemporary universities. The roles of modern college administrators are not only centered on decision-making in developing long-term vision and communicating vision and goals to all stakeholders. Presidents in both public and private colleges and universities are now more accountable to stakeholders, government and the board of trustees. It was recommended that struggling colleges and universities could merge with other institutions that are either flourishing or struggling financially to form a viable institution. Standardizing colleges and universities high college presidents&apos; salaries would be an interesting topic for future research
