Natural Ventilation of Buildings
Natural ventilation is considered a prerequisite for sustainable buildings and is therefore in line with current trends in the construction industry. The design of naturally ventilated buildings is more difficult and carries greater risk than those that are mechanically ventilated. A successful result relies increasingly on a good understanding of the abilities and limitations of the theoretical and experimental procedures that are used for design. There are two ways to naturally ventilate a building: wind driven ventilation and stack ventilation. The majority of buildings employing natural ventilation rely primarily on wind driven ventilation, but the most efficient design should implement ...
The Alarmist
alarmist (pre 2020): Someone who exaggerates a danger and so causes needless worry or panic.alarmist (post 2020): Someone who justifiably raises the alarm about a global danger to Earth's biosphere.His research was urgent fifty years ago. Now, it' s critical.In the early 1970s, budding Kiwi scientist Dave Lowe was posted at an atmospheric monitoring station on the wind-blasted southern coast of New Zealand' s North Island. On a shoestring salary he measured carbon in the atmosphere, collecting vital data towards what became one of the most important discoveries in modern science.What followed was a lifetime' s career marked by hope and despair. As realisation dawned of what his measurements meant for the future of the planet, Dave travelled the world to understand more about atmospheric gases, along the way programming some of the earliest computers, designing cutting-edge equipment and conducting experiments both dangerous and mind-numbingly dull. From the sandy beaches of California to the stark winters of West Germany, the mesas of the Rocky Mountains and an Atlantic voyage across the equator, Dave has faced down climate deniers, foot-dragging bureaucracy and widespread comp
Ten Generations of the Etheredge-Etheridge-Ethridge Family in America
Caleb Etheredge/Etheridge (1721-1791) was the descendant of Thomas Etheridge (1604-1671) who was the first known generation in America. Caleb married Agnes Clarke before 1752. They had eight children. He died in Halifax County, North Carolina. Descendants lived chiefly in the South.
Heads of Families at the First Census of the United States Taken in the Year 1790
This schedule represents a complete list of the heads of families in North Carolina at the time of the adoption of the Constitution. Under law, the marshals were required to ascertain the number of inhabitants within their respective districts, omitting Indians not taxed, and distinguishing free persons (including those bound to service for a term of years) from all others; the sex and color of free persons; and the number of free males 16 years of age and over. The object of the inquiry last mentioned was, undoubtedly, to obtain definite knowledge as to the military and industrial strength of the country.
A History of Atmospheric CO2 and Its Effects on Plants, Animals, and Ecosystems
Based in extensive research in geology, atmospheric science, and paleontology, this book offers a detailed history of CO2 in the atmosphere, and an understanding of factors that have influenced changes in the past. The text illuminates the role of atmospheric CO2 in the modern carbon cycle and in the evolution of plants and animals, and addresses the future role of atmospheric CO2 and its likely effects on ecosystems.
