are fraught with the greatest danger, owing to the destructive influence exerted upon the lungs by the inhaled particles. The rocky particles in this ring may have originated on Io or from meteoritic or cometary debris. Se-79 decays by emitting a beta particle with no attendant gamma radiation. For in time t the mutual action between two particles at P and Q produces equal and opposite momenta in the line PQ, and these will have equal and opposite moments about the fixed axis. It should be pointed out that no measurements on osmotic pressures or freezing points can do more than tell us that an excess of particles is present; such experiments can throw no light on the question whether or not those particles are electrically charged. Dissociation of core particles into open core and genomic RNA The open core particles devoid of genomic dsRNAs were isolated by centrifugation through CsTFA. Particle. When the displacement is represented by Ahbkc the particles on each side of B are displaced towards it 6 7 ?. Example Similar effects are produced along the boulder-clay cliffs of the Baltic. doughnutre composed of energetic charged particles trapped inside the Earth's magnetic field, which surrounds the Earth like a ring donut. Examples of mineral particles in a sentence, how to use it. Then the actual energy of that body is WV2/2g = Waip2/2g. Basically, Japanese particles define what you’re talking about in a sentence. 는/은 and 가/이 both are used for the subject of a sentence but 는/은 introduces a topic or a subject whereas 가/이 identifies a subject. The water, contained in the interstices of the sand above the mean sea-level, would (except in so far as a film, coating the sand particles, is held up by capillary attraction) gradually sink to the sea-level if there were no rainfall. It was then assumed that each of the two constituents of the neutral fluid had an atomic structure and that the so-called particles of one of the electric fluids, say positive, repelled similar particles with a force varying inversely as a square of the distance and attracted those of the opposite fluid according to the same law. The Japanese language uses a total of 188 particles. A natural electric charge on the particles would oppose this tendency, and tend to increase the free surface and thus promote disintegration and solution. The smaller the limestone particles then the quicker your soil will become more alkaline. These fine-grained materials are at first mixed with broken and more or less weathered rock fragments and coarser mineral particles in the soil and subsoil, but by the action of wind and rain they are swept away and deposited in distant situations. In order to avoid the uncertainty arising from the lack of vowels to distinguish forms consisting of the same consonants (for the vowel-points were not yet invented), the aramaising use of the reflexive conjugations (Hithpa`el, Nithpa`el) for the internal passives (Pu'al, Hoph`al) became common; particles were used to express the genitive and other relations, and in general there was an endeavour to avoid the obscurities of a purely consonantal writing. The graphical methods of determining the moment of inertia of a plane system of particles with respect to any line in its plane may be briefly noticed. How To Use Particles In A Sentence? The mature females lay their eggs in the water, and the newly-hatched larvae provide themselves with cases made of various particles such as grains of sand, pieces of wood or leaves stuck together with silk secreted from the salivary glands of the insect. He remarks that it is impossible to suppose that the particles of mastic are in the form of bubbles. "We can now easily conceive," he says, "that in all rain-water which is collected from gutters in cisterns, and in all waters exposed to the air, animalcules may be found; for they may be carried thither by the particles of dust blown about by the winds.". While in some occasions it's possible that they are interchangeable within a sentence with slightly different meanings, there are many distinct differences between these 2 particles. The conductive particles (nano or micro) may be metallic, coated insulating particles or based intrinsically conductive particles (nano or micro) may be metallic, coated insulating particles or based intrinsically conductive polymers. There is not a particle of truth in what he said. Thomson has demonstrated the existence under many different conditions of particles more minute than anything previously known to science. It must not be forgotten, too, that a very moderate increase of dimensions may carry the particles beyond the reach of our approximations. A proton is an elementary particle of matter. Within the pollen-grain is the granular protoplasm with some oily particles, and occasionally starch. If the particles were away, the wave would pass on unbroken and no light would be emitted laterally. These particles become dust like when they dry out and therefore easily airborne, spreading around the house. To ensure this being properly done, the lumps of lime should be broken up small, and enough water to slake them should be added, the lime then being allowed to rest for about forty-eight hours, when the water changes the particles of quicklime to hydrate of lime, and breaks up the hard lumps into a powder. : The major disadvantage of thoria are the environmental issues due to the exposure to the alpha particles emitted by thorium. Particles do not change. Tom Shelley reports Particles fired in a plasma at supersonic speeds are producing metal matrix composites of superior properties at surprisingly modest cost. Assuming that jkerian is right, that there is only one thematic は in a sentence, so the non-first は will always add a hint of … If in the process of glass manufacture a glass vessel is suddenly cooled, the constituent particles are unable to arrange themselves and the vessel remains in a state of extreme tension. The use of filters removes larger particles from tobacco smoke, thus reducing deposition in larger airways. In the application to mechanics these coefficients are the masses of particles situate at the respective points, and are therefore all positive. If the equations of motion of each particle be formed separately, each such internal force will appear twice over, with opposite signs for its components, viz, as affecting the motion of each of the two particles between which it acts. The subsequent experiments of Snellen, Senftleben, and, more lately, of Turner, seem to show that if the eyeball be protected from the impingement of foreign particles, an accident to which it is liable owing to its state of anaesthesia, the ulceration may be warded off indefinitely. Even though the particle of dirt was tiny, it stood out like a sore thumb on my grandmother’s white table cloth. From this it will be seen that the desert in Egypt is mainly a rock desert, where the surface is formed of disintegrated rock, the finer particles of which have been carried away by the wind; and east of the Nile this is almost exclusively the case. This additional postulate may be introduced under various forms. In the first place, with a given size of particles, the direction of complete polarization indicated by (23) is a function of the colour of the light, the value of 0 being 3 or 4 times as large for the violet as for the red end of the spectrum. Images include bile canaliculus, glycogen alpha particles, Kupffer cell, liver, rER & mitochondria, sER, and sinusoids. As particular cases: the mass-centre of a uniform thin triangular plate coincides with that of three equal particles at the corners; and that of a uniform solid tetrahedron coincides with that of four equal particles at the vertices. In doing what he did, Descartes actually exemplified that reduction of the processes of nature to mere transposition of the particles of matter, which in different ways was a leading idea in the minds of Bacon, Hobbes and Gassendi. Besides the sedentary Cirripedia, numbers of the smaller forms, especially among the Entomostraca, subsist on floating particles of organic matter swept within reach of the jaws by the movements of the other limbs. III. Synchrotron A type of circular accelerator in which the particles travel in synchronized bunches at fixed radius. Kinetics of a system of discrete particles. When the wind acts on the surface of the sea it drives before it the particles of the surface layer of water, and, as these cannot be parted from those immediately beneath, the internal friction of the fluid causes the propelling impulse to act through a considerable depth, and if the wind continued long enough it would ultimately set the whole mass of the ocean in motion 'right down to the bottom. (A sentence particle just means a particle that goes on the end of a sentence.) This question I have duly considered, and though I am not able to satisfy myself completely I am nearly persuaded that the circumstance depends on the weight and number of the ultimate particles of the several gases.". If the finer earthy sands only are obtainable, they must be rendered sharper by washing away the earthy particles. The change in the use of particles and the comparative rarity of the definite article form, together with the startling divergence in vocabulary, the chief ground of our perplexity" (Church Quarterly Review, 1903, pp. The gold miner shook each particle of sand out of the sifter, leaving only the sparkling nuggets. Particles are Hiragana-characters attached to the end of a word or phrase to signify their grammatical use in a sentence. In one, the bodies are regarded as material particles, no account being taken of their dimensions. The difference in the verbal particles in the different languages is very great. The alkalis are very interesting; often they form 5 or io% of the whole rock; they indicate abundance of white micas or of undecomposed particles of felspar. adsorbent particles, the conveyance of matter takes place in accordance with various mechanisms. He treated the resultant electric force at any point as analogous to the flux of heat from sources distributed in the same manner as the supposed electric particles. The size of the suspended particles in colloidal solutions varies greatly. In addition, the particles can only be recognized as separate objects if their apparent distance from one another is greater than the angular definition of sight. Dry steam is steam free from mechanically mixed water particles; wet steam, on the other hand, contains water particles in suspension. "Difference in vocabulary may be partially explained (though only partially in this case) by difference of subject-matter and of date; but the use of particles is one of the most unfailing of literary tests. (a) Filaments rigid, non-motile, sheathed: - Crenothrix (Cohn), filaments unbranched and devoid of sulphur particles; Thiothrix (Winogr. A force is said to act upon each of two particles forming a pair, its magnitude being the product of mass and component acceleration of the particle on which it acts, and its direction that of this component acceleration. The phenomenon is due to very fine particles of dust suspended in the high regions of the atmosphere that produce a scattering effect upon the component parts of white light. Another word for particles. The female constructs on a stone a series of cells, built of cement, which she compounds of particles of earth, minute stones and her own saliva. That question can only be answered by examining whether or not the particles move in an electric field. ", Such portion, small enough for the position and motion of each to be sufficiently specified by those of a point, are called "particles.". At the other extreme we know that innumerable swarms of minute bodies, probably little more than particles, move round the sun in orbits of every degree of eccentricity, making themselves known to us only in the exceptional cases when they strike the earth's atmosphere. Just as a granite is a conglomerate or mechanical mixture of distinct crystalline grains of three perfectly definite minerals, mica, quartz, and felspar, so iron and steel in their usual slowly cooled state consist of a mixture of microscopic particles of such definite quasiminerals, diametrically unlike. Centrifugal Couples of a Rotating Body.Besides the tendency (if any) of the combined centrifugal forces of the particles of a rotating body to s/lift the axis of rotation, they may also tend to turn it out of its original direction. to represent the velocities of the several particles mi, mi,.. which expresses the internal kinetic energy in terms of the relative velocities of the several pairs of particles. dispersion of q particles hardens the a phase. For instance, the decay of a Tritium atom releases a beta particle. dirt particles into the nozzle of the cleaner. The rival philosopher, who believes water to be continuous and without spaces between its particles, has a greater difficulty in accounting for the disappearance of the sugar; he would probably say that the sugar, and the water also, had ceased to exist, and that a new continuous substance had been formed from them, but he could offer no picture of how this change had taken place. There is generally a tendency in coals towards cleaving into cubical or prismatic blocks, but sometimes the cohesion between the particles is so feeble that the mass breaks up into dust when struck. Comparison is effected by the use of particles. Hall also reaches the interesting conclusion that the plane in question seems to lie near the invariable plane of the solar system, a result which might be expected if the light proceeded from a swarm of independent meteoric particles moving around the sun. My profile. Let us suppose that the force between two particles m and m' at the distance f is F =mm '(0(f) +Cf2), (22) being reckoned positive when the force is attractive. The Galileo-Newton theory of motion is that, relative to a suitably chosen base, and with suitable assignments of mass, all accelerations of particles are made up of mutual (so-called) actions between pairs of particles, whereby the two particles forming a pair have accelerations in opposite directions in the line joining them, of magnitudes inversely proportional to their masses. In regard to the purification of water, filtration was long looked upon as merely a mechanical process of straining out the solid particles, whereby a turbid water could be rendered clear. The cage is certainly readily penetrated by soil (as dust particles) containing virus, bacteria and fungi along with soil arthropods. This pit, generally filled in the living animal with particles of food, is FIG. Each molecule need not radiate with increased energy, but the more brilliant emission of light may be due to the greater number of particles forming similar vibrating systems. 'I'm going to Spain next week'. Beyond this, wrought iron, and certain classes of steel which then were important, necessarily contained much slag or " cinder," because they were made by welding together pasty particles of metal in a bath of slag, without subsequent fusion. The principle can of course be extended to any system of particles or rigid bodies, connected together in any, way, provided we take into account the internal stresses, or reactions, between the various parts. He shows that, supposing the cloud of particles to move around the sun in nearly circular orbits immediately outside the earth, the perturbations by the earth in the motion of the particles will result in their retardation in that part of the orbit nearest the earth, and therefore in their always being more numerous in a given space in this part of the orbit Ethan in any other. It is taken up from the interstices between the particles of soil exclusively by the finest subdivisions of the fibrils, and in many cases by the extremely delicate thread-like cells which project from them and which are known as root-hairs. Faster-moving particles diffusing from A to B carry their momentum with them, and tend to accelerate B; an equal number of slower particles diffusing from B to A act as a drag on A. The particle is attached to the end of the word, without a space in between the word and the particle. This explanation of the action of the solid is equivalent to that by which Gauss afterwards supplied the defect of the theory of Laplace, except that, not being expressed in terms of mathematical symbols, it does not indicate the mathematical relation between the attraction of individual particles and the final result. As food particles pass in through the mouth they become enveloped in a slimy substance (secreted by the endostyle) and conveyed down the gut by the action of the vibratile cilia as a continuous food-rope, the peristaltic movements of the gut-wall being very feeble. The subject was pursued by Thomson and the Cambridge physicists with great mathematical and experimental ability, and finally the conclusion was reached that in a high vacuum tube the electric charge is carried by particles which have a mass only a fraction, as above mentioned, of that of the hydrogen atom, but which carry a charge equal to the unit electric charge of the hydrogen ion as found by electrochemical researches. The most abundant of the terrigenous materials are the finest particles of clay and calcium carbonate as well as fragments derived from land vegetation, of which twigs, leaves, &c., may form a perceptible proportion as far as 200 m. The floors of the Caribbean, Cayman and Mexican Basins in the Central American Sea are covered with a white calcareous ooze, which is clearly distinguished from the eupelagic pteropod and globigerina oozes by the presence of abundant large mineral particles and the remains of land plants. After examining several hypotheses, he decides this to be fine particles of earth. 428 seq.). In yet another, quantum billiard balls exhibit the strange, probabilistic nature of quantum particles. These bubbles arise partly from the air enclosed between the particles of raw materials and partly from the gaseous decomposition products of the materials themselves. finer; while the pro-eutectoid and eutectoid graphite, if they exist, are probably in very fine particles. It is easily seen from (6) that if the configuration of a system of particles be altered by homogeneous strain (see ELASTICITY) the new position of the mass-centre will be at that point of the strained figure which corresponds to the original mass-centre. Cohn long ago showed that certain glistening particles observed in the cells of Beggiatoa consist of sulphur, and Winogradsky and Beyerinck have shown that a whole series of sulphur bacteria of the genera Thiothrix, Chromatium, Spirillum, Monas, &c., exist, and play important parts in the circulation of this element in nature, e.g. To take a simple example, the important subatomic particle called the electron has a negative electrical charge. 2. the solution dilute enough) for the intermolecular forces between the dissolved particles to be inappreciable. If we assume that a certain minimum electric charge must be brought into contact with a group of colloid particles to produce coagulation, twice as many univalent ions must collect to produce the same effect as a number of divalent ions, and three times as many as an effective number of trivalent ions. solid matter in suspension varies so slightly with the temperature that practically it remains constant, the hot liquor rises to the top of the vessel, and the scums 'and particles of solid matter in suspension separate themselves from it and fall to the bottom. The outermost layer of the endosperm consists of square cells larger and more regular in form than those on each side; these contain aleuron grains - small particles of gluten or nitrogenous matter. It lives on dry, welldrained ground, and digs a deep burrow lined with silk to prevent the infall of loose particles of soil. Where the carbon, in thus diffusing inwards, meets particles of the slag, a basic ferrous silicate which is always present in wrought iron, it forms carbonic oxide, FeO+ C = Fe+CO, which puffs the pliant metal up and forms blisters. Where the sac is completely closed it generally contains no solid particles, but in a few Macrura a single otolith secreted by the walls of the sac is present. A deep porous bed in the upper layers is essential, and this should consist of fine particles which lie close to each other without any tendency to stick together and " puddle " after heavy showers. Also, fine particles may be drawn into the respiratory airways where they may adversely affect health. Sentence Examples. Use ‘particles’ in a sentence | ‘particles’ example sentences . Many particles are closely linked to verbs to form multi-word verbs, such as "go away." The final outcome of these investigations was the hypothesis that Thomson's corpuscles or particles composing the cathode discharge in a high vacuum tube must be looked upon as the ultimate constituent of what we call negative electricity; in other words, they are atoms of negative electricity, possessing, however, inertia, and these negative electrons are components at any rate of the chemical atom. We may easily satisfy ourselves that, in every instance in which the sensation of sound is excited, the body whence the sound proceeds must have been thrown, by a blow or other means, into a state of agitation or tremor, implying the existence of a vibratory motion, or motion to and fro, of the particles of which it consists. When the tide is first admitted the heavier particles, which are pure sand, are first deposited; the second deposit is a mixture of sand and fine mud, which, from its friable texture, forms the most valuable soil; while lastly the pure mud subsides, containing the finest particles of all, and forms a rich but very tenacious soil. The solar wind is a stream of electrically charged particlesblown constantly from the sun. If we divide any of the above quadratic moments by the total mass ~(m), the result is called the mean square of the distances of the particles from the respective plane, axis or pole. Here are some examples of that use of ~은/는 (~eun / neun): NASA has used aerogel to trap tiny particles of space dust for research. At a further stage of their growth the particles disperse in the perpendicular direction a light which is no longer fully polarized. cooling the manufactured objects sufficiently slowly to allow the constituent particles to settle into a condition of equilibrium, is of vital importance. (2) As the concentration of the solutions increases, the ionization as measured electrically and the dissociation as measured osmotically might decrease more or less together, though, since the thermodynamic theory only holds when the solution is so dilute that the dissolved particles are beyond each other's sphere of action, there is much doubt whether this second relation is valid through any appreciable range of concentration. 4 c), and has particles of sand adhering to it, as if the vessel had been filled with sand and subjected to heat, and the inside of the neck has the impression of a metal rod (Plate I. The only motion in the air was that of the dripping, microscopic particles of drizzling mist.
