Abstract: The history of Agriculture in India dates back to Indus Valley Civilisation. India ranks second worldwide in farm outputs. As of 2018, agriculture employed more than 50% of the Indian workforce and contributed 17–18% to the country's GDP. India has the largest net cropped area, followed by the US and China, yet mechanization in farming is comparatively low compared to developed countries. The lack of technological development and unaffordability of new and competent machines for the average farmer are the few of the reasons for this encumbrance. The development of the onion harvester intends that it will provide a reliable and affordable alternative to traditional farming practices. The digging and conveying systems are the integrated part of the onion harvester. The design of the blade and conveyor is made by using CATIA V5 and analysis of the parts are done using ANSYS Workbench. During design and analysis, severe factors are considered such as preventing the damage to onion bulbs, size of bulbs, soil condition, onion leaves at a predetermined height and roots of the crops to penetrate. This paper is intended to discuss the results of the design and analysis of the digging and conveying systems under the guidelines of the SAE TIFAN rulebook [1]. Keywords: Onion Harvester, Blade Design, Conveyor Design, FEA Analysis.

The history of humanity is a history of rationality. As a result, mankind has progressed from the Stone Age to the era of modern medicine, genetics, computer science, robotics, and nanotechnology. The life span of a man in ancient times was about twenty years, and today, in highly developed societies, a man lives, on average, to eighty-six years. Advances in science and technology have not always had a positive impact. Suffice to say, the ongoing environmental problems that seriously affect humanity or, for example, the dietary problems that have resulted due to genetic manipulation. Scientific and technological development must be considered in a serious and philosophical manner. Ethics are increasingly becoming an integral part of life. In this paper, we focused on the new coronavirus that has led to the planetary-wide disease called COVID-19. All countries have engaged in their efforts to suppress the resulting pandemic. However, some of the utilized measures have been suspect: whether to lock-down people in quarantine, whether their movement should be restricted, whether they should be forced to vaccinate, and so on. Claiming to act prophylactically, scientists, by adding some DNA, RNA segments (gain of function, GOF) to an innocuous human virus, have created a dangerous artificial influenza virus. Likewise, an artificial, infectious coronavirus was created in a laboratory. Both procedures for creating these dangerous, hybrid viruses have been described in eminent scientific journals. The scientists involved in this research told us that they wanted to find cures and vaccines for these non-natural viruses on the off-chance they ever appeared among humans; when carefully handled, engineered organisms provide a unique opportunity to study biological systems in a controlled fashion. Biotechnology is a powerful tool to advance medical research and should not be abandoned because of irrational fears. But the chance of this type of virus appearing among humans is almost non-existent. However, what if these viruses "escape" from the lab, as has happened in the recent past? What if a terrorist organization start producing these viruses on their own according to detailed instructions and then use them? Finally, since the two great world powers, the US and China, that jointly created the artificial coronavirus, called SHC014-MA15, who can stop them from continuing this practice? Isn't it possible that they also created the current SARS-CoV-2 provoking a death of two and a half million people? Related to these questions, this study deals with the issue of tolerance. A large number of world-renowned scientists really believe that the current cause of the pandemic, SARS-CoV-2, is an artificial, laboratory-created virus, presenting a number of facts for this. It is not disputed that their claims are arguable. This, however, does not mean that their opponents, pharmaceutical companies and some superpowers, who have far greater political and economic power, have to incorrectly and utterly embarrass them all over, morally discredit them, nor ban their texts on the subject. In science, the struggle must be waged by arguments, not by totalitarian Orwellian methods.

AbstractThis chapter introduces the concept and a definition of the “formalization” of banking supervision that is examined in this book and outlines the aim and scope of the book. In addition to providing the reader with an overview of the history of banking supervision in eight developed countries (the US, Japan, Sweden, Germany, Switzerland, Belgium, France, and the UK), the book presents information regarding the formalization process itself. That process is assessed based on three criteria—bank regulation, supervisory authority, and supervisory activity. This approach is intended to provide more detail than a simple assessment based on banking acts that is common in financial regulation research. The aim of the analysis undertaken in this book is to identify why the history of banking supervision in various countries shares many similarities and yet also displays many differences. In Sect. 1.5, we provide an overview of the historiography of the formalization of banking supervision with a special emphasis on comparative and internationally oriented literature, while the growing body of literature on each of the national cases is discussed in subsequent chapters.

This article demonstrates that Russias funding for research and development is less than 2.5 % of global funding, whereas the amount of financing of just three countries, the USA, China, and Japan amounts to 50%. It is argued that the inadequacy of Russias domestic financing for the development of the science sector vis a vis that of developed countries allows the country to prioritize only a limited number of research fields in its scientific and technological development. We have compared and contrasted expenditures on research and development in biomedicine in the USA and Russia. It has been demonstrated that in 2014, basic funding for 27 research centers included in the US National Health Institutes network exceeded the amount of financing for 104 Russian medical scientific and research institutes subordinated to the Russian Ministry of Health and Federal Agency of Scientific Organizations by 173 times. We have concluded that a substantial increase in state funding for fundamental, exploratory, and applied research in the field of biomedicine is required if life sciences are to be preserved as one of the priorities in the scientific-technological and social development of Russia. It is also necessary to eliminate all administrative and tax barriers that prevent active participation of domestic industrial entities in the co-financing of the development of Russian drugs and medical equipment.

The triad of diarrhea, dementia, and dermatitis constitutes the clinical diagnosis of pellagra. However, most reported cases of pellagra have occurred without all components of the triad. Pellagra was declared eradicated in the United States after an outbreak in the 1920s, and is now considered to be an exceedingly rare diagnosis in developed countries. In this article, we present a case of a 56-year-old man who presented with a significant history of alcohol use and chronic diarrhea. Pellagra was clinically diagnosed based on the triad of diarrhea, cognitive dysfunction, and dermatitis in this malnourished, alcoholic patient. The patient was treated and clinically improved with resolution of his diarrhea and cognitive dysfunction.


Migration and Modernities recovers a comparative literary history of migration by bringing together scholars from the US and Europe to explore the connections between migrant experiences and the uneven emergence of modernity. The collection initiates transnational, transcultural and interdisciplinary conversations about migration in the eighteenth and nineteenth centuries, demonstrating how mobility unsettles the geographic boundaries, temporal periodization, and racial categories we often use to organize literary and historical study. Migrants are by definition liminal, and many have existed historically in the spaces between nations, regions or ethnicities. In exploring these spaces, Migration and Modernities also investigates the origins of current debates about belonging, rights, and citizenship. Its chapters traverse the globe, revealing the experiences — real or imagined — of eighteenth- and nineteenth-century migrants, from dispossessed Native Americans to soldiers in South America, Turkish refugees to Scottish settlers. They explore the aesthetic and rhetorical frameworks used to represent migrant experiences during a time when imperial expansion and technological developments made the fortunes of some migrants and made exiles out of others. These frameworks continue to influence the narratives we tell ourselves about migration today and were crucial in producing a distinctively modern subjectivity in which mobility and rootlessness have become normative.

The article is devoted to the problem of the social state as one of the fundamental constitutional principles of the state structure of modern developed countries. The course of historical development of philosophical and legal thought on this problem is considered. The idea of a close connection between the concept of the social state and the ideas of utopian socialism of Thomas More and Henri Saint-Simon is put forward. Liberals also made a significant contribution to the development of the idea of the social state, they argued that the ratio of equality and freedom is a key problem for the classical liberal doctrine. It is concluded that the emergence of the theory of the social state for objective reasons was inevitable, since it is due to the historical development of society.
