Webtv. The Binocular Site. The Binocular Site Spotting scopes offer a compromise between binoculars and telescopes, as they offer the higher power of a telescope with a more compact size that you would associate with binoculars.
Although their magnifications will be higher than binoculars, they usually have tripods of only 12” to 18” high that can be placed on a table if needed. They are naturally smaller, lighter, and less expensive than full-sized telescopes but maintain high optical quality through the use of glass, coatings, eyepieces, and other elements. Spotting scopes also produce an upright image, whereas larger astronomy telescopes will reverse the image seen.
As you might expect, this is essential for scopes used for birdwatching and other terrestrial activities. Spotting scopes were originally used during target shooting competitions as shooters checked their distant target or where shots hit without leaving the shooting position.

PostNatural Organism of the Month: During the late 1950's a large-scale public works program was initiated to eradicate the live-flesh-eating screwworm plaguing cattle ranches across the American south.
The screwworm is the larval stage of the fly, Cochliomyia hominivorax. Full-scale fly factories were produced in Florida and Texas capable of producing 500 billion sterile male flies per week. The factories were optimized to expedite each stage of the fly's life and to sort them by gender prior to their emergence from the pupae.
Male screwworms, at the age of 5 ½ days, were loaded into metal tubes and carried by a lone worker to the irradiation facility where they were exposed to a radioactive sample of Cobalt 60, permanently ending their reproductive capacity.

During summers in my homestate of Michigan I spent much of my childhood at my maternal grandparents' home a few miles from our house.
They lived across the street from a Nurses' Home, part of a larger hospital complex, which was surrounded by parklike grounds and towering trees. My favorite tree was an old, gnarled oak with wide-spreading branches that grew on a spacious lawn in front of the Nurses' Home. I don't remember seeing fireflies on our side of the street, perhaps because of nearby children and activity. But the hospital grounds were private, quiet, and serene. To reach their residence, the nurses used convenient rear doors that were closer to the hospital beyond; the front area, closest to my grandparents, remained undisturbed, a world apart. Other children sometimes snuck across the street and tried to catch "lightning bugs," as we called them, and put them in Mason jars. Open Society Institute and Soros Foundations Network. VisibleGovernment.ca - Home. About Participle. We believe there needs to be a new settlement between individuals, communities and government - new ways for people to get involved in determining their lives in a meaningful way, new approaches that mean some people do not get stuck at the bottom of the heap for generations and new bonds that mean people can flourish and bring their dreams alive.
We also think that what matters is not just ideas, but real change on the ground, in our communities. On an everyday level this means public service reform - this is where the opportunities lie, to build something different. Participle’s vision is radical: public services which offer all citizens a fair chance to realise their potential. For citizens to have this chance, it is not enough for society to present them merely with opportunities. There must be a shared commitment to developing citizens’ capabilities, so that all can acquire the skills necessary to seize and shape opportunities. Our Inheritance The Future.
