Before we continue, let's agree on some basics:calcium is an element, calcite and dolomite are minerals, and limestone is a sedimentary rock which can turn into the metamorphic rock called marble if the right conditions occur. Igneous rocks cool from molten magma and form the majority of the...

aDifferent gradient operators can be applied to estimate image gradients from the input image or a smoothed version of it. The simplest approach is to use central differences: 不同的梯度算子可以被应用于估计图象梯度从输入图象或一个使光滑的版本的它。 最简单的方法将使用中心差分:[translate] ...
Since wood is a natural material that can be used for a long period of time, it makes sense to think that wooden decks are better for the planet. This may be true some of the time, but not always. For example, the chemicals used to treat wood under pressure are often toxic. Cedar,...
of ichthyosaurs repeatedly over time. The embryos are quite advanced in their physical development; their paddles, for example, are already well formed. One specimen is even preserved in the birth canal. In addition, the shale contains the remains of many newborns that are between 20 and 30 ...
The key example here is Saturn's moon Titan, which boasts an environment that is rich in prebiotic conditions and organic chemistry, which some scientists think could support exotic lifeforms. In the end, scientists search for known biomarkers like water andcarbon dioxidebecause they are associated...
with millions of alveoli, the tiny air sacs where gas exchange occurs. These alveoli have an enormous surface area--90 times greater than that of your skin--so they make it easy for THC and other compounds to enter the body. The smoke is absorbed by the lungs just seconds after inhaling...
