El documento describe cómo los científicos ya no dudan que el fenómeno de El Niño afectará las costas de América en los próximos tres meses. Explica que la temperatura del océano Pacífico está aumentando y, si las condiciones oceánicas y climáticas continúan, El Niño podría golpear el continente americano en ese plazo. También menciona algunas organizaciones de apoyo como defensa civil, municipios y la Cruz Roja que podrían ayudar ante las consecuencias del fenómeno.
The document summarizes William Barrett's 1864 experiment where he measured the amount of carbon dioxide in human breath using infrared radiation. He collected expired air in rubber bags from subjects before and after meals or exertion. The air was passed through an insulated cylinder with infrared radiation generated at one end. The heat absorbed by the breath gases was measured and used to calculate the carbon dioxide percentage, which was confirmed with chemical analysis. The experiment demonstrated measuring carbon dioxide in breath using infrared absorption and recognized the potential clinical application of this technique. It was an important early application of infrared spectroscopy.
Mr. Wood won the open division and set a new state record in the senior division of 3D archery shoots in Washington and Idaho without using a traditional peep sight. By developing his style of shooting with the Anchor Sight, Mr. Wood was able to acquire targets faster, shoot accurately to long distances of 90 yards, and edge out competitors to win the tournaments. The document advertises the Anchor Sight as allowing archers freedom from peep sights while developing consistency in their shooting form.

The document discusses the key elements of an effective fundraising offer: specificity, cost, impact, and urgency. It explains that a good offer presents a specific action or item for the donor to fund, assigns a appropriate cost, convinces the donor their donation will have a large impact, and creates a sense of urgency for the donor to act now. The document provides examples of ineffective, non-specific offers and emphasizes that a compelling offer allows donors to directly contribute to change. It concludes by offering assistance from the company, TrueSense Marketing, to help craft strong fundraising offers.
