Exhaust gases emitted by heat sources must be discharged into the atmosphere in the most dependable manner possible without endangering human health. This is possible because the chimneys are connected to the heat source. There are some guidelines for locating chimneys in relation to existing structures, determining the minimum height, and calculating the chimney section. The performance of the heat source is also directly affected by the correct sizing of the chimneys. The large diameter of the chimney at a fixed height causes hot air inside the heat source to be thrown into the atmosphere more than necessary, resulting in …

Engineering: Cleaning Water, Producing Food, Building Shelters, Graham T. Reader Dr.
Windsor Turbulence and Energy Lab
Human survival requires that we drink water, eat food, breath sufficiently oxygenated air, and enjoy a safe shelter. Historically, shelter was perhaps the most important since, as hunter-gathers, wild animals, fish, and uncultivated plants provided the food sources while rivers, streams, lakes, and surface pools supplied the drinking water. Shelter protected against the vagaries of weather, climate, and possible animal attacks, including other humans. In the provision of these needs, artisans, skilled trades, technicians, and engineers have played pivotal roles since erect human beings first populated the Earth. In a global survey seven out of ten people think engineers’ societal …

Mitigate Or Adapt?, Graham T. Reader
Thriving Through Climate Change and Pandemic 2021
Any changes in climate prior to the 19th century are attributed to natural causes, largely due to external factors. However, since 1992 such natural climate changes have been defined as climate variabilities by the United Nations Framework Convention on Climate Change (UNFCCC). Modern changes in climate, using the same framework, are presumed to be caused by human activities, especially from the emissions of Greenhouse Gases (GHG) generated from the combustion of fossil fuels. Subsequently, instead of humans finding ways to adapt to changes in climate by such measures as migration, precipitation harvesting, flood prevention, and irrigation, mitigation has become the …

America Vs. Apple: The Argumentative Function Of Metonyms, Ilon Lauer, Thomas Lauer
OSSA Conference Archive
: Our study of public argumentation surrounding iPhone encryption addresses the argumentative function of the metonym. Metonyms accomplish general and specific argumentative purposes. Generally, metonyms help define and redefine the argumentative framework for a dispute. Within a controversy, metonyms operate as inference generators. We isolate and analyze several metonyms and elaborate their warrant-generating valences. Metonyms are inference generating tools capable of instantiating normative frameworks, invoking flexible and indeterminate senses of causality.
