PEAR

What's New and Beneficial About Pears For nutritional reasons, we're often advised to consume the skins of fruits. However, it's less often that research provides strong evidence in support of this advice. Recent studies have shown that the skin of pears contains at least three to four times as many phenolic phytonutrients as the flesh. These phytonutrients include antioxidant, anti-inflammatory flavonoids, and potentially anti-cancer phytonutrients like cinnamic acids. The skin of the pear has also been show to contain about half of the pear's total dietary fiber. In recent studies measuring risk of type 2 diabetes in U.S. women, pears have earned very special recognition. Researchers now know that certain flavonoids in food can improve insulin sensitivity, and of special interest in this area have been three groups of flavonoids (flavonols, flavan-3-ols, and anthocyanins). All pears contain flavonoids falling within the first two groups, and red-skinned pe...

Aubauf Method - Building Up

Image
Atoms Are Built Up by Adding Electrons Although the nucleus of an atom is very dense, the electrons around it can take on a variety of positions which can be summarized as an electron configuration. An element's electron configuration can be represented using energy level diagrams, or Aufbau diagrams. The Aufbau principle (from the German Aufbau meaning "building up, construction") describes a model-building method in which an atom is "built up" by progressively adding electrons. As electrons are added, they assume the most stable shells with respect to the nucleus and the electrons already present. Filling in an Aufbau Diagram The order in which orbitals are filled is given by the Madelung rule. The rule is based on the total number of nodes in the atomic orbital, n + ℓ, which is related to the energy. In this context, n represents the principal quantum number and ℓ represents the azimuthal quantum number. The values ℓ = 0, 1, 2, 3 correspo...
