Zao may refer to:
The James Bond novels and films are notable for their memorable villains and henchmen. Each Bond villain has numerous henchmen to do their bidding.
There is typically one particularly privileged henchman who poses a formidable physical threat to Bond and must be defeated in order to reach the employer. These range from simply adept and tough fighters, such as Donald 'Red' Grant, to henchmen whose physical characteristics are seemingly superhuman, such as Jaws.
Zao /ˈzeɪ.oʊ/ is a metalcore band from Parkersburg, West Virginia. Founded in March 1993, Zao has hosted several musicians and endured numerous roster changes to the point where no original members remain. Former drummer Jesse Smith, singer Daniel Weydant, and guitarists Scott Mellinger & Russ Cogdell are seen by most fans as the "core" of Zao.
Christianity has been a key influence in the band's work; because the founding members claimed to have a strong relationship with God, they were considered a devoted Christian band, which changed as time passed. Former drummer Jesse Smith slowly changed the band's vision. Because only half the band's members identified themselves as Christians, Zao no longer considered itself a Christian band but rather a group of open-minded artists. Lyrics in future productions may or may not include Christian messages, but Zao has stated they would have loved to return to the Christian Cornerstone Festival when it was still active. As of 2015, only one member of the band claims Christianity as their beliefs.
A particle is a minute fragment or quantity of matter. In the physical sciences, the word is used to describe a small localized object to which can be ascribed several physical or chemical properties such as volume or mass; subatomic particles such as protons or neutrons; and other elementary particles. The word is rather general in meaning, and is refined as needed by various scientific fields. Something that is composed of particles may be referred to as being particulate. However, the term particulate is most frequently used to refer to pollutants in the Earth's atmosphere, which are a suspension of unconnected particles, rather than a connected particle aggregation.
The concept of particles is particularly useful when modelling nature, as the full treatment of many phenomena is complex. It can be used to make simplifying assumptions concerning the processes involved. Francis Sears and Mark Zemansky, in University Physics, give the example of calculating the landing location and speed of a baseball thrown in the air. They gradually strip the baseball of most of its properties, by first idealizing it as a rigid smooth sphere, then by neglecting rotation, buoyancy and friction, ultimately reducing the problem to the ballistics of a classical point particle. The treatment of large numbers of particles is the realm of statistical physics.
A particle in the physical sciences is a small localized object to which can be ascribed physical properties.
Particle may also refer to:
In marine and freshwater ecology, a particle is a small object. Particles can remain in suspension in the ocean or freshwater. However, they eventually settle (rate determined by Stokes' law) and accumulate as sediment. Some can enter the atmosphere through wave action where they can act as cloud condensation nuclei (CCN). Many organisms filter particles out of the water with unique filtration mechanisms (filter feeders). Particles are often associated with high loads of toxins which attach to the surface. As these toxins are passed up the food chain they accumulate in fatty tissue and become increasingly concentrated in predators (see bioaccumulation). Very little is known about the dynamics of particles, especially when they are re-suspended by dredging. They can remain floating in the water and drift over long distances. The decomposition of some particles by bacteria consumes a lot of oxygen and can cause the water to become hypoxic.
Particle levels in water (or air) can be measured with a turbidity meter and analyzed with a particle counter. They can also be scanned with an underwater microscope, such as ecoSCOPE. Collected particles of size 20 - 200 micrometers hovering in the free water in the vicinity of a harbor had the following contaminant levels (table). Many of those contaminants are carcinogenic.
