Propeller planes and small engine aircraft around the United States, legally utilize leaded aviation gasoline. The purpose of this experiment was to collect suspended particulate matter from a university campus, directly below an airport’s arriving flight path’s descent line, and to analyze lead content suspended in the air. Two collection sets of three separate samples were collected on six separate days, one set in July of 2018 and the second set in January 2019.

Acquiring companies prefer growth through acquisitions and mergers rather than growth by direct investment in manufacturing resources. A justification for the large number of take-overs is the belief that abnormal gains are to be obtained so. There is substantial empirical evidence showing this untrue. Take-overs contribute immediate short-term gains, and are preferred to internal expansion where the benefits accrue over the long-term. Managers are usually evaluated on short-term performance criteria and therefore they have a bias for take-overs. Several investigators have studied the decline of the United States economy and the corresponding rise of Japan as industrial leader. The unrestrained take-over activity has been the chief reason for the decline of many industries in the United States. Acquiring companies have contributed to their own downfall by not investing sufficiently in up-to-date manufacturing resources. Take-overs lead to economic decline caused by lower productivity of acquired resources. South African companies are showing a strong preference for growth through take-overs. With the take-over process many local industries have come under the control of a few large conglomerates. South African acquiring companies could benefit by following the Japanese example of direct investments in technologically up-to-date manufacturing resources. More direct investment in manufacturing resources will lead to a more vigorous free-enterprise system and will raise the productivity of local industries. A more stringent Competition Act is necessary if South Africa is to avoid the harm to the economy caused by unrestrained take-over activity.

Abstract Deliberations over the COVID-19 pandemic's long-term effects on the global balance of power have spurred a large and rancorous debate, including speculation about a shift in the definition of national security and prescriptions about where it should focus. That argument will no doubt continue. But we argue that one consequence is already evident: the United States has spent the last seventy years portraying itself as a security provider in all key domains—for many an intrinsic component of its status as a global leader. One reasonable broad conclusion from the US struggle with COVID-19 is that it has further forfeited its broad leadership position on the basis of its behaviour. Yet that, although possibly true, would only portray one element of the story. The more profound insight exposed by COVID-19 is of a new reality: in a world where both naturogenic and anthropogenic threats pose immense national security challenges, decades of mistaken assumptions and policy choices have created a new environment, one where the United States has been redefined as a security consumer, at least in terms of international public health issues associated with the spread of deadly infectious diseases.
