Vitamin D supplementation and calcium absorption during caloric restriction: a randomized double blind trial

submitted by: shapses
Background: Weight loss (WL) is associated with a decrease in calcium absorption and may be one mechanism that induces bone loss with weight reduction. Objective: Because vitamin D supplementation has been shown to increase true fractional calcium absorption (TFCA), the goal of this study was to examine the effect of vitamin D during WL or weight maintenance (WM). Design: A randomized, placebo-controlled, double-blind 6-wk study was conducted in 82 postmenopausal women [BMI (in kg/...

Approaches to Evaluating and Improving Lithium-Ion Battery Safety

submitted by: RASEIBoulder
As lithium-ion battery technologies mature, the size and energy of these systems continues to increase for emerging applications in transportation, grid storage, military use and aerospace. In fact, broadening the application space for lithium-ion batteries from the consumer electronics industries to these emerging markets increases their size from 1-50 Wh batteries for smart phones and laptops to >50 kWh for electric vehicles (EVs) and MWh scale for utility storage systems. As these...

When Newlands made an analogy between his Law of Octaves and the musical scale he was laughed at by the members of the English Chemical Society, and his paper describing this law was rejected. But Newlands was not so disparate. Seeking musical patterns in natural phenomena has been a frequent endeavour throughout history. The Greek philosopher and mathematician Pythagoras of Samos argued that celestial bodies in rotation gave off pitched sounds that blended into a cosmic harmony, which he...

According to the Big Bang theory, after inflation stopped, the universe consisted of a quark–gluon plasma, as well as all other elementary particles. A few seconds later, quarks and gluons combined to form baryons such as protons and neutrons. The first nuclei were formed about three minutes after the Big Bang; neutrons combined with protons to form the hydrogen and helium content of the first stars. This process is called Big Bang nucleosynthesis. In the Big Bang nucleosynthesis...
