Abstract Carotid artery stenting has become a viable alternative to carotid endarterectomy in the management of carotid stenosis. Over the past 20 years, many trials have attempted to compare both treatment modalities and establish the indications for each one, depending on clinical and anatomic features presented by patients. Concurrently, carotid stenting techniques and devices have evolved and made endovascular management of carotid stenosis safe and effective. Among the most important innovations are devices for distal and proximal embolic protection and new stent designs. This paper reviews these advances in the endovascular management of carotid artery stenosis within the context of the historical background.

World over life was going at its normal pace when an outbreak occurred in Hubei province of China in the later part of the year 2019. This outbreak was soon found to be caused by a virus named coronavirus (COVID-19). Rapidly the virus spread globally leading to a pandemic. The mortality rate was increasing day by day and helplessly everyone was wondering what actually could be done to prevent the spread. Lessons from the past epidemic made it possible to think that maintaining social distancing and adequate hygiene might help to combat the ailment. In India, majorly affected were the people from poor strata and the businessmen who were earning their daily bread by selling things of daily need. The health sector too witnessed an alarming ratio of patients suffering from COVID-19. The second wave, which soon followd the first wave, caused much more havoc. Overall, the COVID-19 pandemic, exposed and challanged the health security system of every country. As the danger of pandemic still prevails, steps to curtail the spread of disease and future management strategies should be formulated from the lessons learnt through the COVID-19 phase.

This chapter focuses on a defunct version of high school girls' basketball known as “six-on-six” and how it expressed community identity in Iowa. Throughout the twentieth century, more than a million Iowa high school girls played the half-court, two-dribble version of basketball known as “six-on-six.” Originally conceived to accommodate girls and women's perceived physical limitations, six-on-six basketball often lent itself to fast-paced, high-scoring, crowd-rallying competitions. This chapter first provides a historical background on six-player basketball in Iowa before discussing how girls' six-on-six basketball has been relegated to the past, yet lives on in many places and memories, thanks in part to new technologies and understandings of community. It argues that the history of Iowa's six-player basketball is alive and thriving in alternative forms, citing the emergence of new, transitory communities to sustain its remembrance. The chapter considers two sites: a 2003 reunion game that gathered former players and supporters, and a Facebook page which fosters a virtual kinship of more than 7,000 members.

During the past twenty-five years, heat transfer enhancement has grown at a rapid rate to the point where it can be regarded as a major field of endeavor, a second-generation heat transfer technology. After some historical background, mention of the driving trends, and a review of the various convective enhancement techniques, four areas of major contemporary interest are discussed: structured surfaces for shellside boiling, rough surfaces in tubes, offset strip fins, and microfin tubes for refrigerant evaporators and condensers. The review concludes with developments in the major areas of application.

The stratigraphic knowledge of Panama was, until now, spread over hundreds of scientific/geologic publications written during the past 120 years. The construction of the Panama Canal during the early twentieth century helped galvanizing the engineering and geological disciplines to understand the tectonic, sedimentation and biodiversity of the Cenozoic Era in this part of the world. Later, few petroleum companies arrived on the scene and contributed to our knowledge of the sub-surface. The past thirty years saw a surge of studies by many institutions in areas away from the Canal, such as in Darien, Azuero Peninsula, Bocas del Toro, and the Burica Peninsula near the Costa Rica Border. Our most recent knowledge came from the widening of the Panama Canal between 2007 and 2016. It is from all these older and recent studies that the present Lexicon draws its content. It provides the historical background of all described geological units in Panama and summarizes the lithological and paleontological knowledge of each units in an easy-to-search format.
