Glen Helen Nature Preserve
The Glen Helen Nature Preserve is a nature reserve immediately east of Yellow Springs, Ohio, United States. The initial 700-acre parcel was given to Antioch College by Hugh Taylor Birch in memory of his daughter Helen Birch Bartlet in 1929, and is the largest private nature preserve in the region. About The Glen is immediately adjacent to the main Antioch College campus (which itself contains restored natural areas managed by The Glen) and stretches in land area for . Together with the of the John Bryan State Park and the of the Clifton Gorge State Nature Preserve, the area comprises a river corridor of over 2,100 contiguous acres that has been rated "exceptional" by the Ohio Department of Natural Resources for its cleanliness and biodiversity. The preserve was designated a National Natural Landmark in 1965. The patches of land now included in Glen Helen previously had a number of different uses. While some were always natural, other areas were farmed, some grazed, and some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ohio
Ohio () is a state in the Midwestern region of the United States. Of the fifty U.S. states, it is the 34th-largest by area, and with a population of nearly 11.8 million, is the seventh-most populous and tenth-most densely populated.

Nature Centers In Ohio
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Protected Areas Of Greene County, Ohio
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servi ...

Wax Thermostatic Element
The wax thermostatic element was invented in 1934 by Sergius Vernet (1899–1968). Its principal application is in automotive thermostats used in the engine cooling system. The first applications in the plumbing and HVAC, heating industries were in Sweden (1970) and in Switzerland (1971). Wax thermostatic elements transform heat energy into mechanical energy using the thermal expansion of waxes when they melt. This wax motor principle also finds applications besides engine cooling systems, including heating system thermostatic radiator valves, plumbing, industrial, and agriculture. Automotive thermostats The internal combustion engine cooling thermostat maintains the temperature of the engine near its optimum operating temperature by regulating the flow of coolant to an air cooled radiator (engine cooling), radiator. This regulation is now carried out by an internal thermostat. Conveniently, both the sensing element of the thermostat and its control valve may be placed at the same ...

COVID-19
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by a virus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Miami Valley
The Miami Valley is the land area surrounding the Great Miami River in southwest Ohio, USA, and includes the Little Miami, Mad, and Stillwater rivers as well. Geographically, it includes Dayton, Springfield, Middletown, Hamilton, and other communities. The name is derived from the Miami Indians. Commonly, however, it refers to the economic and cultural-social region centered on the Greater Dayton area . Middletown and Hamilton both fall under the economic and cultural-social influence of Cincinnati and thus are not commonly included in this sense. Institutions and enterprises in the Dayton area, such as Miami Valley Career Technology Center, Miami Valley HospitalMiami Valley Young Marines Miami Valley Council of the Boy Scouts of America and Miami Valley Storytellers illustrate local usage. History During the mid-twentieth century, among the largest employers in the Valley were Procter & Gamble in Cincinnati, Champion Paper and Fiber in Hamilton, Armco in Middletown, and ...

Mound Builders
A number of pre-Columbian cultures are collectively termed "Mound Builders". The term does not refer to a specific people or archaeological culture, but refers to the characteristic mound earthworks erected for an extended period of more than 5,000 years. The "Mound Builder" cultures span the period of roughly 3500 Common Era, BCE (the construction of Watson Brake) to the 16th century CE, including the Archaic period in the Americas, Archaic period, Woodland period (Calusa culture, Adena culture, Adena and Hopewell cultures), and Mississippian culture, Mississippian period. Geographically, the cultures were present in the region of the Great Lakes, the Ohio River Valley, and the Mississippi River valley and its tributary waters. The first mound building was an early marker of political and social complexity among the cultures in the Eastern United States. Watson Brake in Louisiana, constructed about 3500 BCE during the Archaic period in the Americas, Middle Archaic period, is cu ...

Adena Culture
The Adena culture was a Pre-Columbian Native American culture that existed from 500 BCE to 100 CE, in a time known as the Early Woodland period. The Adena culture refers to what were probably a number of related Native American societies sharing a burial complex and ceremonial system.

Old-growth Forest
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree height ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
