In order to mark a distinction with the traditional triennial reports, for this legacy issue we have asked our present and past OC members, as well as a few other outstanding members of the Celestial Mechanics community, to write a short essay on “recent highlights and the future of Celestial Mechanics”. Below we collect the contributions of the people who responded to our invitation. As it is natural, each of them interpreted their task differently. Some produced a dissertation on broad and general aspects, others focused on a specific topic of their interest. Some considered that their role was to provide a detailed review, with a list of key references, others preferred to mention the topics for which progress has been significant but without quoting any references, implicitly considering that this progress was possible thanks to the collective efforts of many scientists, and not just a few. This is great, as we appreciate the diversity of attitudes and opinions.

AbstractCOVID-19 is the third spread of animal coronavirus over the past two decades, resulting in a major epidemic in humans after SARS and MERS. COVID-19 is responsible of the biggest biological earthquake in the world. In the global fight against COVID-19 some serious mistakes have been done like, the countries’ misguided attempts to protect their economies, lack of international co-operation. These mistakes that the people had done in previous deadly outbreaks. The result has been a greater economic devastation and the collapse of national and international trust for all. In this constantly changing environment, if we have a better understanding of the host-virus interactions than we can be more prepared to the future deadly outbreaks. When encountered with a disease which the causative is unknown, the reaction time and the precautions that should be taken matters a great deal. In this review we aimed to reveal the molecular footprints of COVID-19 scientifically and to get an understanding of the pandemia. This review might be a highlight to the possible outbreaks.

Volcanic eruptions affect land and humans globally. When a volcano erupts, tons of volcanic ash materials are ejected to the atmosphere and deposited on land. The hazard posed by volcanic ash is not limited to the area in proximity to the volcano, but can also affect a vast area. Ashes ejected from volcano’s affect people’s daily life and disrupts agricultural activities and damages crops. However, the positive outcome of this natural event is that it secures fertile soil for the future. This paper examines volcanic ash (tephra) from a soil security view-point, mainly its capability. This paper reviews the positive aspects of volcanic ash, which has a high capability to supply nutrients to plant, and can also sequester a large amount of carbon out of the atmosphere. We report some studies around the world, which evaluated soil organic carbon (SOC) accumulation since volcanic eruptions. The mechanisms of SOC protection in volcanic ash soil include organo-metallic complexes, chemical protection, and physical protection. Two case studies of volcanic ash from Mt. Talang and Sinabung in Sumatra, Indonesia showed the rapid accumulation of SOC through lichens and vascular plants. Volcanic ash plays an important role in the global carbon cycle and ensures soil security in volcanic regions of the world in terms of boosting its capability. However, there is also a human dimension, which does not go well with volcanic ash. Volcanic ash can severely destroy agricultural areas and farmers’ livelihoods. Connectivity and codification needs to ensure farming in the area to take into account of risk and build appropriate adaptation and resilient strategy.

In any consideration of the future of the states, it is desirable at the outset to recall the circumstances of their development and of their entry into the Union. When the present Constitution was framed and adopted, the states were more than a century and a half old. At that time, and for many years thereafter, it was the states to which the people gave their primary allegiance. Under the Articles of Confederation, the strength of the states was so great that the central government was unable to function; when the Constitution was framed, the people were still greatly concerned about “states' rights.” This priority of the states in the federal system continued through the nineteenth century, down to the period of the Civil War; in the closing decades of that century, state government sank into the depths in an orgy of graft and corruption and inefficiency, which resulted in a wave of state constitutional restrictions, particularly upon legislative powers.At this time, when the prestige and efficiency of the state governments were at their lowest ebb, there began to appear ringing indictments of the whole state system. Most conspicuous of these were the well known writings of Professors John W. Burgess, of Columbia University, and Simon N. Patten, of the University of Pennsylvania.

AbstractAstronomy is connected with the every day experiences of the people, since the observation of simple and repetitive phenomena, as the succesion of days and nights, untill events of high impact, as the total solar eclipses. In this sense, the Astronomy is a fascinating activity and can be used to inspire interest in sciences in general. In this contribution, we introduce the Network of Astronmy School Education as part of the IAU proposals connected with teaching training programs, and we highlight several examples on the specific topic of the eclipses: their importance and connection with the culture, that can capture students attention if we use the workshops as part of the classes.

Exploring the roots of four keywords for our times: Europe, the citizen, the individual, and the people, Mariarosaria Gianninoto’s and James Underhill’s Migrating Meanings (2019) takes a broad view of conceptualization by taking on board various forms of English, (Scottish, American, and English), as well as other European languages (German, French, Spanish & Czech), and incorporating in-depth contemporary and historical accounts of Mandarin Chinese. The corpus-based research leads the authors to conclude that the English keywords are European concepts with roots in French and parallel traditions in German. But what happens to Chinese words when they come into contact with migrating meanings from Europe? How are existing concepts like the people transformed? This book goes beyond the cold analysis of concepts to scrutinize the keywords that move people and get them excited about individual rights and personal destinies. With economic, political and cultural globalisation, our world is inseparable from the fates of other nations and peoples. But how far can we trust English to provide us with a reliable lingua franca to speak about our world? If our keywords reflect our cultures and form parts of specific cultural and historical narratives, they may well trace the paths we take together into the future. This book helps us to understand how other languages are adapting to English words, and how their worldviews resist ‘anglo-concepts’ through their own traditions, stories and worldviews.

AS A WAY OF REACHING IMPORTANT POLITICAL DECISIONS, THE referendum is usually regarded as a clumsy and unsatisfactory instrument and quite unimportant as a contribution to political democracy. Yet widespread demands for more participation ‘by the people’ have brought the referendum into new-found favour. Interest has been rekindled too by its application to the issue of membership of the European Community, with the clear possibility of directly comparing the referenda in the four countries involved. This new interest in the referendum comes at a time when many party systems, the traditional supports of a purely parliamentary democracy, appear to be in disarray, and there are signs of increasing volatility within electorates which can foreshadow basic realignments in party systems. Questions now are naturally being raised about the future ordering of democratic politics, and for this reason it seems justifiable to focus an examination of the referendum especially on the problem of political change.

I tend to approach cities from and through their margins because this is the path that makes most sense to me. I grew up on the urban fringe in Elizabeth, a ‘satellite town’ north of Adelaide. Founded along the lines of the British new towns, Elizabeth was named for a queen who, to her credit, always popped out for a visit whenever she was around. By 1960, Elizabeth had a car factory, 30, 000 British migrants and a path into the future that would come to haunt it as its factories were downsized and its public housing was turned first into welfare housing and then — in the picturesque language of new prejudices — into ‘housing of last resort’ for the people no one wanted.

Como consecuencia de la devastación a la que se verá sometida Teruel durante la guerra civil española gran parte del núcleo urbano se verá afectado. Esta dramática situación planteará la necesidad reconstruir la ciudad pero también la posibilidad de renovar la trama urbana. En el presente artículo se estudiaran las distintas propuestas llevadas a cabo durante este proceso, la tensión entre las ideas reformistas que entenderán la situación como una oportunidad renovadora sin prejuicios e ideas mucho más conservacionistas preocupadas por la identidad histórica de la ciudad, enfrentarán a los distintos agentes involucrados y finalmente dará lugar a la definitiva actuación propuesta. Es imprescindible conocer y reflexionar sobre una sucesión de ideas que plasmadas sobre el papel pueden decidir el futuro de un pueblo, pero también la conservación de su pasado, de su memoria.As a result of the devastation which will come under Teruel during the Spanish civil war much of the urban area will be affected. This dramatic situation arises the need to rebuild the city but also the possibility of renewing the urban fabric. In this article, the various proposals made during this process will be evaluated. The tension between reformist ideas to understand the situation as a renewed and unprejudiced opportunity and much more conservationist ideas concerned with the historical identity of the city will create a confrontation between different involved agents and ultimately lead to the final proposed action. It is essential to know and think of a series of ideas that once reflected on paper can decide the future of the people, but also the preservation of their past, their memory.
