This lessens eyestrain.
This leads to deterioration of agriculture and lessens the production.
Indian coal usually contains phosphoric acid, which greatly lessens its value for iron-smelting.
The Mississippi valley tribes are nearly brachycephalic; the index increases around the Great Lakes, and lessens farther east.
The combination of ductility, which lessens the tendency to break when overstrained or distorted, with a very high limit of elasticity, gives it great value for shafting, the merit of which is measured by its endurance of the repeated stresses to which its rotation exposes it whenever its alignment is not mathematically straight.
Manganese by itself rather lessens than increases the malleableness and, indeed, the general merit of the metal, but it is added intentionally, in quantities even as large as 1 5 to palliate the effects of sulphur and oxygen.
The advantage of this combination is that, by simplifying the conditions with which the composition of the pig iron has to comply, it makes the management of the blast furnace easier, and thus lessens the danger of making " misfit " pig iron, i.e.
Not only does it relieve the spasm, but it lessens the amount of secretion - often dangerously excessive - which is often associated with it.
But it undoubtedly prolongs life, lessens suffering, and by checking the growth of bacteria upon the cancer reduces the fetid odour and the symptoms of septic intoxication.
Probably drapery assists by absorbing the sound to some extent, and thus it lessens the echo besides breaking it up. (J.
The quantity obtained from each fir is very variable, depending on the vigour of the tree, and greatly lessens after it has been subjected to the operation for some years.
Ing the dorsal with the ventral sclerites of the Lateral thoracic abdomen, lessens t he capacity of the abdo ternal femoral minal region, while the contraction of the power Longit.
The climbing of ladders from deep mines not only lessens the efficiency of the men by reason of fatigue, but often tends to increase the mortality from diseases of the heart.
North of the apex of the delta and the boundary between the deltaic and inland tracts, the rainfall gradually lessens as far as Minbu, where what was formerly called the rainless zone commences and extends as far as Katha.
As a verb, the word means to stifle or check; hence damped vibrations or oscillations are those which have been reduced or stopped, instead of being allowed to die out naturally; the "dampers" of the piano are small pieces of feltcovered wood which fall upon the strings and stop their vibrations as the keys are allowed to rise; and the "damper" of a chimney or flue, by restricting the draught, lessens the rate of combustion.
As, however, the temperature developed is a function of the time needed to complete the action, the degree of heat attained varies with every form of generator, and while the water in one form may never reach the boiling-point, the carbide in another may become red-hot and give a temperature of over 800° C. Heating in a generator is not only a source of danger, but also lessens the yield of gas and deteriorates its quality.
High, may be that this frictional resistance becomes so great as actually to interrupt the even descent of the charge, parts of which are at times suspended like a ball in the rising jet of a fountain, to fall perhaps with destructive violence when some shifting condition momentarily lessens the friction.
The depth of the small drain at the junction is made about as great as that of the main drain, and it gradually lessens towards the taper to 6 in.
For on the one hand knowledge of the fact that nitrite of amyl lessens blood pressure has led to the successful employment of other nitrites and bodies having a similar action, and on the other the knowledge that increased blood pressure tends to cause anginal pain leads to the prohibition of any strain, any food, any exposure to cold, and also of any medicines which would unduly raise the blood pressure.
A combination of the two kinds of remedy is sometimes useful, and chloral sometimes succeeds when other things fail, because it depresses the circulation as well as lessens the activity of the brain-cells.
During its continuance fat is absorbed from the subcutaneous tissue, and patients become very much thinner, so that it not only lessens flatulence, but reduces obesity.
Alkaline waters containing a little common salt are perhaps even more important than the pure alkaline, as the salt lessens the depressing effect of the alkali.
The whole of the operation must, of course, be completed in the few days - five to ten - during which the capsules are capable of yielding the drug: A cold wind or a chilly atmosphere at the time of collection lessens the yield, and rain washes the opium off the capsules.
During the summer months the general course of the wind along the sea-coast is interrupted about midday by an incoming current of air, the " sea breeze," which gradually increases until about three o'clock in the afternoon, and then gradually lessens until the offshore wind takes its place.
It has in addition a markedly depressing action upon the respiratory centre, it lessens all the secretions except the sweat, and diminishes bowel peristalsis and the size of the pupil.
In Lombardy it has a breadth of 200 yds., and a depth of 10 to 16 ft., but the strength of the current renders its navigation very difficult, and lessens its value as a means of transit between Germany and Italy.
It has an extraordinary power over the pain of acute gout; it lessens the severity and frequency of the attacks when given continuously between them, and it markedly controls such symptoms of gout as eczema, bronchitis and neuritis, whilst it is entirely inoperative against these conditions when they are not of gouty origin.
Annually); elsewhere, in Karamojo and the northern regions, the rainfall lessens to about 20 in.
But if the heat is given at the instant of greatest rarefaction, the increase of pressure lessens the difference from the undisturbed pressure, and lessens the potential energy, so that during the return less kinetic energy is formed and the vibration tends to die away.
If the pitch is raised still further the dissonance lessens, and when there are about 130 beats per second the interval is consonant.
Large size has here, as in most metallurgical operations, not only its usual advantage of economy of installation, labour and administration per unit of product, but the further very important one that it lessens the proportion which the outer heat-radiating and hence heatwasting surface bears to the whole.
It is true that the use of the " mixer " (§ 77) lessens these variations, and that there are convenient ways of mitigating their effects.
- Manganese in many cases, but not in all, opposes the formation of graphite and thus hardens the iron, and it lessens the red shortness (§ 40), which sulphur causes, by leading to the formation of the less harmful manganese sulphide instead of the more harmful iron sulphide.
