Following transposition and docking, the crew noticed the exterior surface of the Lunar Module was giving off particles from a spot where the LM's skin appeared torn or shredded ; at one point, Charlie Duke estimated they were seeing about five to ten particles per second.

Later they appeared in electrodynamics, when describing the motion of charged particles in electric and magnetic fields.

But while the amounts of radioactive iodine particles detected in the soil at Iitate village appeared to be declining from high levels, the overall situation at Fukushima remained very serious ," with IAEA Director General Yukiya Amano's comment " It would take more time than people think.

The blade whirred and appeared to pass through her body, as ripping sounds were heard, the woman shrieked, and particles were scattered by the whirring blade.

In 1958 he observed a patch of white within the crater, and a spectrum of the area appeared to reveal an emission cloud of carbon particles.

The result was a historic paper which appeared in 1914, in which Einstein and Fokker observed that the Lagrangian for Nordström's equation of motion for test particles,, is the geodesic Lagrangian for a curved Lorentzian manifold with metric tensor.

* Blackboard chalk is a substance used for drawing on rough surfaces, as it readily crumbles leaving particles that stick loosely to these surfaces.

There are about 10 < sup > 80 </ sup > fundamental particles in the observable universe, by rough estimation.

The interior is normally very smooth or lined with fine bubbles ; the exterior is generally coated with rough sand particles and is porous.

The linearity assumption is usually a good rough approximation, although deviations can occur ( especially pronounced for particles heavier than the proton at low energies ).

This is due in part to attrition and abrasion which results from the stones colliding with each other and against the river channel, thus removing the rough texture ( rounding ) and reducing the size of the particles.

A rough picture of this is that pairs of virtual particles emerge from the vacuum near the event horizon, with one member of a pair being captured, and the other escaping the vicinity of the black hole.

Colloidal particles are bigger, and are in the rough vicinity of the size of a wavelength of light.

But, if the colloid particles are spheroid, Tyndall scattering is mathematically analysable in terms of Mie theory, which admits particle sizes in the rough vicinity of the wavelength of light.

The rough surfaces of these particles makes it easy for them to bind with other toxins in the environment, thus increasing the hazards of particle inhalation.

Methods like crushing and cutting are also used for reducing particle diameter, but produce more rough particles compared to the two previous techniques ( and are therefore the early stages of the micronization process ).

Before it begins to develop, the morphological characteristics of a MSC are: a small cell body with a few cell processes that are long and thin ; a large, round nucleus with a prominent nucleolus that is surrounded by finely dispersed chromatin particles, giving the nucleus a clear appearance ; a small amount of Golgi apparatus, rough endoplasmic reticulum, mitochondria, and polyribosomes ; and the cells are widely dispersed within an extracellular matrix that is devoid of every type of collagen except for a few reticular fibrils.

Alumina nanoparticles at 0. 1 % can increase the critical heat flux of water by as much as 70 %; the particles form rough porous surface on the cooled object, which encourages formation of new bubbles, and their hydrophilic nature then helps pushing them away, hindering the formation of the steam layer.

The outer two rings in the stack consist of seven α subunits each, which serve as docking domains for the regulatory particles and the alpha subunits N-termini form a gate that blocks unregulated access of substrates to the interior cavity.

The washing process whereby soils are removed consists basically of applying mechanical action to loosen the dirt particles and dried matter in the presence of water which helps to float off the debris and acts, to some extent, as a dissolving and solvating agent.

Obviously hydrophobic ( oleophilic ) substances such as greases, oils, or particles having a greasy or oily surface are more at home in the center of a micelle than in the aqueous phase.

The charged particles then repel each other and are also repelled from the charged surface, which almost invariably bears a negative charge under washing conditions.

The flux values are for all particles with masses greater than the given mass and are based on an estimate of the numbers of visual meteors.

The natural anatomical and physiological defensive features of the upper respiratory tract, such as the turbinates of the nose and the cilia of the trachea and larger bronchi, are capable of impinging out the larger particles to which we are ordinarily exposed in our daily existence.

Very small particles, however, in a size range of 1 to 4 microns in diameter are capable of passing these impinging barriers and entering the alveolar bed of the lungs.

Certain other properties of small particles, in addition to those already mentioned in connection with penetration of the respiratory tract, are noteworthy in defense considerations.

Examples of such situations are ( aerial ) night reconnaissance, the recording of radioactive tracers in live body tissues, special radiography in medical or industrial applications, track recording of high energy particles, etc..

Then, too, misplaced or jammed-together teeth are prone to trapping food particles, increasing the likelihood of rapid decay.

In turn the other teeth are likely to decay because food particles may become impacted in them.

These balls are moving in great circles and ellipses, and are of course, the electrons, the particles of negative electricity which by their action create the forces that tie this atom of calcium to the neighboring atoms of oxygen and make up the solid structure of my finger bone.

A suggestion from Louis De Broglie, a physicist in France, showed us that these electrons are not point particles but waves.

Water is drawn in through their mouths, which are usually at the bottom of their heads, and passes through branchial food traps between their mouths and their gills where fine particles are trapped in mucus and filtered out.

The crystal lattice of solid americium and its compounds contains intrinsic defects, which are induced by self-irradiation with alpha particles and accumulate with time ; this results in a drift of some material properties.

Thus he overturned the belief that atoms are the indivisible, ultimate particles of matter.

The constituent particles of an atom are the electron, the proton and the neutron.

In the Standard Model of physics, electrons are truly elementary particles with no internal structure.

However, both protons and neutrons are composite particles composed of elementary particles called quarks.

The gluon is a member of the family of gauge bosons, which are elementary particles that mediate physical forces.

Neutrons and protons were found to be hadrons, or composites of smaller particles called quarks.

Though the word atom originally denoted a particle that cannot be cut into smaller particles, in modern scientific usage the atom is composed of various subatomic particles.

A chemical anisotropic filter, as used to filter particles, is a filter with increasingly smaller interstitial spaces in the direction of filtration so that the proximal regions filter out larger particles and distal regions increasingly remove smaller pales, resulting in greater flow-through and more efficient filtration.

A large-scale attack using anthrax would require the creation of aerosol particles of 1. 5 to 5 microns: larger particles would not reach the lower respiratory tract, while smaller particles would be exhaled back out into the atmosphere.

This is a simulation of the Brownian motion of a big particle ( dust particle ) that collides with a large set of smaller particles ( molecules of a gas ) which move with different velocities in different random directions.

Gravity tends to make the particles settle, whereas diffusion acts to homogenize them, driving them into regions of smaller concentration.

Because of the size exclusion, the colloidal particles are unable to pass through the pores of an ultrafiltration membrane with a size smaller than their own dimension.

The smaller the catalyst particle size, the larger the surface area for a given mass of particles.

The general concept of a chemical reaction has been extended to non-chemical reactions between entities smaller than atoms, including nuclear reactions, radioactive decays, and reactions between elementary particles as described by quantum field theory.

This is possibly explained by the fact that he sent out 60 arahants to the known world to spread his teaching ; however it differs in the fact that the Buddha taught that the four elements are false and that form is in fact made up of much smaller particles which are constantly changing.

The smaller particles of clay result in a larger surface area that can hold water.

Larger and higher-velocity rain drops have greater kinetic energy, and thus their impact will displace soil particles by larger distances than smaller, slower-moving rain drops.

Tillage also increases wind erosion rates, by dehydrating the soil and breaking it up into smaller particles that can be picked up by the wind.

* In physics, nuclear fission is a process where a large atomic nucleus ( such as uranium ) is split into two smaller particles.

In particle physics, an elementary particle or fundamental particle is a particle not known to have substructure, thus it is not known to be made up of smaller particles.

In December 1960, he suggested the existence of a shell of visible dust particles around the earth some 600 to in space, beyond which there was a layer of smaller particles, a micrometre or less in diameter, extending 2, 000 to.

Radar studies showed the 1966 storm included a relatively high percentage of smaller particles while 1965's lower activity had a much higher proportion of larger particles.
